The base742is fixed on the rack72and is spaced from the driver73. Two slots746are defined on the base742adjacent to the driver73. The two slots746are spaced from each other and located at two lateral sides of the rack72respectively. A baffle748is protruded from the base742away from the rack72. The baffle748is located between the resetting portion76and the arrester77to limit the arrester77. Please also referring toFIG. 12, the cover744recesses towards the driver73to define a cavity7442. The cavity7442is configured for receiving the support75. The cavity7442defines an inserting hole7445at a sidewall adjacent to the driver73. The inserting hole7445is communicated with the cavity7442. The cavity7442defines a hole7446at a sidewall away from the driver73along the sliding direction of the rotor33. The hole7446is configured for receiving the resetting portion76. In the embodiment, there are two holes7446. The holes7446are opposite to each other and spaced from each other to penetrate the sidewall of the cavity7442away from the driver73.

Please referring toFIGS. 12 and 13, the support75includes a plank752, and a front plate753, a rear pole754, an extension755and a side plate757formed on the plank752towards the rack72and spaced from each other. The front plate753is formed on an end of the plank752away from the driver73. The front plate753forms two tines7532on a surface away from the rack72. The rear pole754is substantially a “” shape. The rear pole754is located on an end of the plank752away from the front plate753. An end of the rear pole754away from the front plate753can penetrate through the inserting hole7445of the cover744. The rear pole754defines a hole7542along the sliding direction of the rotor33. The extension755is substantially a trapeziform shape. The extension755is protruded at a central portion of the plank752. The extension755has two inclined surfaces7552. A distance between the two inclined surfaces7552reduces gradually along a direction away from the driver73. The extension755and the rear pole754define a sliding space756therebetween. The side plate757each are formed on a lateral side of the front plate753and towards the rear pole754. The side plate757has two inclined sidewalls7572corresponding to the inclined surfaces7552.

The guiding block772is slidably received in the guiding passage758. The meshing portion774is coupled on the sliding body771and penetrates through the slot746slidably. The meshing portion774has tooth coupled with the rack72. When the guiding block772moves along the guiding passage758away from the driver73, the meshing portion774moves in the slot746to mesh with the rack72, thereby limiting a movement between the setting element39and the rotor33. When the guiding block772moves along the guiding passage758towards the driver73, the meshing portion774moves in the slot746away from the rack72to dis-mesh with the rack72, thereby maintaining the movement between the setting element39and the rotor33.

Please referring toFIGS. 9, 10 and 12, in the illustrated embodiment, the elastic element79is received in the support7542of the rear pole754and is located between the support75and the arrester77. The detent assembly70further includes a block78. The block78is mounted on the sliding space756slidably and is located between the elastic element79and the arrester77. Two ends of the elastic element79abut against the block78and the support75respectively. Two holding portions782are formed on the block78protruding towards the front plate753. The two holding portions782are spaced from each other. Each holding portion782abuts the guiding block772of the arrester77and the sliding body771at two opposite sides.

When the machining equipment100is assembled, please referring toFIG. 3again, the two stators31are fixed in the seat10in parallel. Each of the two rails35is fixed on a corresponding31. The rotor33is slidably mounted between the two stators31. The slip element37with the setting element39mounted thereon is slidably fixed on a corresponding35. The bar51with the liquid ingoing head55mounted thereon is fixed onto the setting element39. The sleeve52is fixed onto the seat10. One end of the pipe53is slidably penetrated through the sleeve52to expose out of the10, the other end of the pipe53is fixed onto the bar51. The pole54is fixed onto the pipe53and the machining tool58is fixed on the pole54. The first liquid outgoing head56and the second liquid outgoing head57are fixed onto the pole54, and the protrusion5631of the first liquid outgoing head56and the second liquid outgoing head57face the machining tool58laterally. The lid501with the frustum502mounted thereon is fixed onto the pole54.

When the detent assembly70is assembled, please referring toFIGS. 9-12again, the support75is slidably received in the housing744, and the resetting portion76is received in the hole7446. The elastic element79is received in the support7542of the rear pole754. The block78is slidably mounted in the sliding space756. The guiding block772of the arrester77is slidably received in the guiding passage758. The base742and the sliding body771are mounted on the base742at two opposite sides. The meshing portion774is slidably penetrated through the slot746of the base742. The base742and the driver73are fixed on the rack72and spaced from each other. The rack72is fixed onto the setting element39and extends along the direction of the rotor33.

When the machining equipment100is used, one end of the tube59is communicated with the liquid ingoing head55, and the other end of the tube59is communicated with cooling liquid. Power is supplied on the two stators31. The rotor33will slide along the passage313under electromagnetic induction principle. The rotor33drives the setting element39to move and also drives the two slip elements37to slide on the rail35. Meanwhile, the driver73is connected to the housing74to limit a movement of the support75with respect to the housing74towards the resetting portion76. Here, the resetting portion76is in compression. When the support75moves to a predetermined position with respect to the housing74, the baffle748of the housing74slide in the groove759from two tines7532therebetween to abut the arrester77, thereby limiting a movement of the arrester77along with the support75. The support75continues to move towards the resetting portion76under a drive of the driver73. Here, the arrester77moves along the guiding passage758of the support75away from the resetting portion76to make the meshing portion774of the arrester77away from the rack72, thereby smoothing the glide between the setting element39and the rotor33. In addition, the arrester77can press the elastic element79when the arrester77moves along the guiding passage758of the support75away from the resetting portion76. The setting element39drives the machining assembly50under the drive of the rotor33to machining the workpiece with the machining tool58. In the above machining process, the cooling liquid enters into the liquid ingoing head55to flow to the protrusion5631of the first liquid outgoing head56and the protrusion5631of the second liquid outgoing head57through the pipe531continuously and gush over the machining tool58to cool the machining tool58sufficiently.

When the electricity fails for the machining equipment100, the driver73stops to work. The resetting portion76forces the support75to move towards the driver73under elastic recovery, meanwhile, the arrester77is forced to move along the guiding passage758towards the resetting portion76. The meshing portion774of the arrester77moves towards the rack72to mesh with the rack72, thereby limiting the movement between the setting element39and the rotor33. When the resetting portion76drives the arrester77to move towards the driver73along with the support75, the setting element39and the rotor33are driven to move towards the driver73and away from the workpiece.

It is to be further understood that even though numerous characteristics and advantages have been set forth in the foregoing description of exemplary embodiments, together with details of the structures and functions of the exemplary embodiments, the disclosure is illustrative only; and that changes may be made in detail, according in matters of shape, size, and arrangement of parts within the principles of the disclosure to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
