Title: Waxing device

Description:
BACKGROUND 
     1. Technical Field 
     The present disclosure relates a waxing device, generally to a waxing device of a polishing machine. 
     2. Description of Related Art 
     The housings of electronic devices need polishing to achieve a mirror finish. Polishing wheels of polishing machines may need a waxing treatment before using. Manual waxing is one method or procedure for such waxing treatment, but the whole procedure of manual waxing is both time and labor consuming. In addition, the waxing quality depends on the expertise and effort of the operators. In related art, waxing devices are applied to polishing wheels. However, pressures applied to the polishing wheels are non-uniform during the waxing process, which results in undue wear of the polishing wheels. Furthermore, such waxing devices need to adjust cutting tool after changing each new wax, and this consumes more time. 
     Therefore, there is room for improvement within the art.

In an alternative embodiment, the adjusting wire  47  could be designed to be an endless wire loop, and the adjusting wire  47  connects the bolt  435  and the pulley wheel  45 . 
     The driving mechanism  50  is positioned on the first sidewall  411 . In illustrated embodiment, the driving mechanism  50  is a cylinder. The driving mechanism  50  includes a basing body  51  and a pushing member  53  movably positioned on the basing body  51 . The basing body  51  is mounted on the first sidewall  411 . The basing body  51  can drive the pushing member  53  into a reciprocating motion vertically with the sliding rail  17 . The pushing member  53  includes a first connecting portion  531  and a second connecting portion  533 . The first connecting portion  531  is movably positioned on the basing body  51 . The second connecting portion  533  is substantially perpendicularly extending from an edge of the first connecting portion  531 . The second connecting portion  533  is away from the mounting block  43 . 
     The mounting assembly  60  is assembled with the second connecting portion  533 . The mounting assembly  60  includes a mounting member  61  and a clamping element  65 . The mounting member  61  is substantially a planar board. The mounting member  61  is installed on the second connecting portion  533 . The mounting member  61  includes a first mounting surface  611  and a second mounting surface  613  positioned opposite to the first mounting surface  611 .

An installing hole  651  is defined through the middle of the clamping element  65 . 
     The motor  70  which includes a rotating shaft  71  is installed on the first mounting surface  611 . The wax block  80  is substantially a thick disc with a through hole  83  in the middle thereof, and the periphery thereof is a round surface  81 . The first rotating shaft  71  passes through the shaft hole  615  of the mounting member  61 , the through hole  83  of the wax block  80 , and finally assembles with the installing hole  651  of the clamping element  65 . The wax block  80  rotatably sleeves on the first rotating shaft  71 . The clamping element  65  sleeves on the first rotating shaft  71  and secures the wax block  80  in place. 
     The detecting assembly  90  is assembled with the mounting member  61  for detecting the consumption of the wax block  80 . The detecting assembly  90  includes a detecting rod  91 , a triggering end  93 , a second rotating post  94 , a detecting roller  95 , and a detector  97 . The detecting rod  91  includes a mounting end  911  and a detecting end  913 . A rotating hole  915  is defined in the mounting end  911  and in the detecting end  913 , respectively. The second rotating post  94  passes through the rotating holes  915  of the mounting end  911 , the mounting hole  617  and the triggering end  93  for installing the detecting rod  91  on the second mounting surface  613  and the triggering end  93  on the first mounting surface  611 . The triggering end  93  is able to rotate a same angle with the detecting rod  91  thereof. The detecting roller  95  is rotatably assembled with the detecting end  913  and rests lightly against the round surface  81 . The detector  97  is positioned on the first mounting surface  611  between the motor  70  and the triggering end  93 . A receiving groove  971  is formed in the detector  97  to receive the triggering end  93 . 
     In assembly, the sliding rail  17  is fixed on the supporting base  13 . The resisting mechanism  20  is positioned on the supporting base  13 . The fixing block  15  is fixed on the supporting base  13 . The adjusting base  41  and the pulley wheel  45  are assembled onto the sliding rail  17  and the fixing block  15 , respectively. The mounting block  43  is mounted on the adjusting base  41 . The extendable portion  23  resists the sensor  44 . The driving mechanism  50  is connected with the first sidewall  411 . The mounting member  61  is positioned on the second connecting portion  533 . The motor  70  is positioned on the first mounting surface  611  so that the first rotating shaft  71  passes through the shaft hole  615 . The wax block  80  and the clamping element  65  sleeve on the first rotating shaft  71 . The wax block  80  is clamped between the clamping element  65  and the second mounting surface  613 . The adjusting wire  47  hangs around the pulley wheel  45 , and one end of the adjusting wire  47  is connected with the bolt  435 . The hanging weight  49  hangs from the other end of the adjusting wire  47 . 
     The wax block  80  is distant from the waxing wheel  200  at the beginning of the wax procedure. When the polishing wheel  200  needs to be waxed, the extendable portion  23  begins to draw or move backward, but doesn&#39;t leave the resisting groove  431 . The sensor  44  detects action of the extendable portion  23  and begins to measure the waxing time. The adjusting base  41  also begins to move toward the polishing wheel  200  because of the decreasing resistance effect between the extendable portion  23  and the sensor  44 . The driving mechanism  50 , the mounting assembly  60 , the motor  70  and the wax block  80  are also driven to move toward the polishing wheel  200  by the adjusting base  41 . 
     The round surface  81  presses lightly on the surface of the polishing wheel  200  when the adjusting base  41  arrives at a preset position. The pushing member  53  begins to undergo a reciprocating motion when plumbed on the sliding rail  17 . The wax block  80  is driven to rotate by the motor  70  and rotates the polishing wheel  200 . The wax will be coated uniformly on the polishing wheel  200  by means of the friction between the wax block  80  and the polishing wheel  200 . The extendable portion  23  pushes the mounting block  43  back to its initial position after the preset waxing time. 
     The detecting roller  95  resists against the round surface  81 . The detecting rod  91  tilts with the decreasing diameter of the wax block  80 . The triggering end  93  tilts accordingly toward the detector  97 . The detector  97  issues a warning when the triggering end  93  arrives at within the receiving groove  971 , which signifies that the wax block  80  needs to be changed or replaced. A new polishing wheel  200  is also needed when the wax block  80  becomes so worn out to the point that it cannot make contact with the polishing wheel  200  when the adjusting base  41  arrives at the preset position. 
     The waxing device  100  has a very simple arrangement and configuration. The adjusting base  41  slidably sleeves on the sliding rail  17 . The resisting mechanism  20  resists the mounting block  43  for adjusting the pressure of the wax block  80  applied to the polishing wheel  200  during the waxing treatment procedure. The driving mechanism  50 , the motor  70  and the wax block  80  are driven to move toward the polishing wheel  200  through the adjusting base  41 . This means that the cutting tool adjusting process is not necessary when a new wax block  80  is substituted for a worn wax block  80 . In addition, the circular wax block  80  replaces the traditional strip-shaped wax block. The wax block  80  retains a circular shape during this process. The wax block  80  is driven to move in two perpendicular directions, and this has the net result that allows for the wax to be coated uniformly on the polishing wheel  200 . Furthermore, efficient consumption of the wax block  80  will be improved upon because the clamping of the wax block  80  requires the smallest possible area. 
     It is believed that the present embodiments and their advantages will be understood from the foregoing description, and it will be apparent that various changes may be made thereto without departing from the spirit and scope of the disclosure or sacrificing all of its material advantages.
