Title: Deburring machine

Description:
BACKGROUND 
     1. Technical Field 
     The present disclosure relates to a deburring machine, and particularly to a deburring machine for removing burrs from workpieces mechanically and in massive quantities. 
     2. Description of Related Art 
     Metal workpieces have burrs that have been leftover during a mechanical machining process. Removal of such burrs helps to prevent injury to workers and improves the workpieces appearance. The burrs left in the side walls of holes or grooves of the metal workpieces, especially on some small workpieces, are removed by manual deburring one at a time. However, the whole procedure of manual deburring is both time and labor consuming. In addition, the workpieces are easily damaged during the manual deburring treatment procedure. 
     Therefore, there is room for improvement within the art.

In the illustrated embodiment, the fourth driver  83  is a motor; the fifth driver  87  is a cylinder. 
     The three deburring units  89  are positioned parallely on the second pushing member  85  and spaced from each other. Each deburring unit  89  includes a supporting member  891 , a sixth driver  893  and a deburring head  895 . The supporting member  891  is perpendicularly positioned on the second pushing member  85 . The sixth driver  893  is mounted on an end of the supporting member  891  away from the second pushing member  85 , and facing the transport mechanism  30  for driving the deburring head  895  to rotate under high speed. The deburring head  895  is rotatably mounted on the sixth driver  893 , between the sixth driver  893  and the second pushing member  85 . In the illustrated embodiment, the sixth driver  893  is a motor; the deburring head  895  is a polishing wheel. 
     The controlling device  90  is mounted on the framework  10  above of the transport mechanism  30  and the rotating mechanism  50 . The controlling device  90  is electrically connected with the transport mechanism  30 , the rotating mechanism  50 , and the deburring mechanism  80  so as to control the operation of the deburring machine  100 . 
     In assembly, the transport mechanism  30  is first mounted on the framework  10 . The first, second mounting members  51  and  52  are positioned on the loading plate  35 . Then the second driver  54  is positioned on the loading disc  35 , between the first and second mounting members  51 ,  52 . The rotating assembly  57  is assembled with the sliding seat  53 . The sliding seat  53  is movably assembled with the first and second mounting members  51 ,  52 . The second driver  54  is connected with the top board  531 . Alter that, the third driver  55  is positioned on the top board  531  and extends inward into the receiving space  530 . The four guiding rails  70  are positioned on the support table  13  adjacent to the rotating assembly  57  and away from the counter  15 . The fourth driver  83  is positioned on the supporting table  13 . The first pushing member  81  is slidably positioned on the four guiding rails  70  and connected with the fourth driver  83 . The second pushing member  85  and the fifth driver  87  are mounted on the first pushing member  81 , respectively. The three deburring units  89  are assembled with the second pushing member  85 . The controlling device  90  is finally positioned above of the framework  10 . 
     When the deburring machine  100  is in use, the workpieces  200  needing or requiring deburring treatment are sleeved on each first rotating member  337  of the first loading member group  371 , respectively. The workpieces  200  are transported to the deburring mechanism  80  and placed under the rotating assembly  57  when the muti-station rotating plate  33  rotates anticlockwise or clockwise  120  degrees. The second driver  54  drives the sliding seat  53  to move toward the loading plate  35 . Each second rotating member  577  moves down and connects with the workpiece  200  configured under each second rotating member  577 . The third driver  55  drives the second rotating members  577  to rotate. Each workpiece  200  connecting with each second rotating member  577  is driven to rotate. The first pushing member  81  is driven to move towards the rotating assembly  57  along the guiding rails  70 . The deburring heads  895  are driven to rotate by the sixth driver  893 . The deburring heads  895  remove the burrs of the workpieces  200  when the first pushing member  81  reaches the preset position. The second pushing member  85  is driven to reciprocate along the first pushing member  81 . The workpieces  200  are transported to the third loading member group  375  when the preset deburring time arrives or reached. At the same time, a new batch of workpieces  200  are transported for receiving the deburring process treatment, and the workpieces  200  that have been debarred are taken down. 
     The transport mechanism  30  includes multi-stations. Therefore, the uploading, deburring and unloading procedures of workpieces  200  can be done at the same time. The transport mechanism  30  and the rotating mechanism  50  position the workpieces  200  accurately during the deburring process treatment. The workpieces  200  are driven to rotate by the rotating shaft  574 ; the deburring head  895  is driven to perform a cycling motion along the first pushing member  81 . So the deburring head  895  removes the burrs of the workpieces  200  totally and cleanly. The deburring machine  100  mechanically removes massive quantities of burrs from the workpieces  200  because of the cooperation of the transport mechanism  30 , the rotating mechanism  50 , the deburring mechanism  80  and the control of the controlling device  90 . 
     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.
