A reverse chamfering mechanism 5 is installed in the middle, a touch control screen 6 is installed above the feeding mechanism 3, and a discharge structure is installed on the left side of the front chamfering mechanism 4. The feeding mechanism 3, the reverse chamfering mechanism 5, the front chamfering mechanism 4, the touch control screen 6 and the discharge mechanism 7 are all distributed along the circumference of the indexing table 103. The circumferential structure distribution facilitates the chamfering work of the lever in the later stage. The feeding mechanism 3 includes a frame 301, and a silo 302 is installed on the frame 301. The silo 302 is filled with multiple groups of levers 2. 2 is provided with a stacking area 303, a push plate 304 is movably connected to the left side of the bin 302, a feeding cylinder 305 is fixedly connected to the frame 301, a slide bar 306 is slidably connected in the feeding cylinder 305, the slide bar 306 is fixedly connected to the push plate 304, a limiting cylinder 8 is fixedly connected in the front chamfering mechanism 4 and the back chamfering mechanism 5, a top plate 801 is slidably connected in the limiting cylinder 8, the top plate 801 is in contact with the lever 2, the unloading mechanism 7 includes a support frame 701, the support A conveyor belt 702 is installed on the support frame 701, and a discharge cylinder 703 is installed on the support frame 701. A sliding rod 704 is slidably connected to the discharge cylinder 703, and a base 705 is fixedly connected to the sliding rod 704. A pulling cylinder 706 is fixedly connected to the base 705, and a pulling rod 707 is slidably connected to the pulling cylinder 706. The base 705 is located above the conveyor belt 702. The cooperation between the base 705 and the pulling cylinder 706 is conducive to disengaging the lever 2 on the work station 104, so as to facilitate the subsequent unloading work.

[0021] When the chamfering device for the lever in the copper pipe rack is actually used, the touch control screen 6 sends a work instruction to the relevant mechanism on the workbench 1. First, the loading mechanism 3 starts to work, and the feeding cylinder 305 drives the slide bar 306 to drive the push plate 304 to work. The push plate 304 enters the silo 302 to push out the lever 2 in the silo 302. After being pushed out, the lever 2 enters the position of the workstation 104 in the indexing table 103. At this time, the indexing table 103 is in a stationary state. After the workstation 104 receives the filling of the silo 302, the motor 101 cooperates with the rotor 102 to drive the indexing table 103 to rotate. Both the motor 101 and the feeding cylinder 305 adopt gap operation. The lever 2 on the workstation 104 moves driven by the motor 101 and the rotor 102. When the reverse chamfering mechanism 5 reaches the position, the limit cylinder 8 in the reverse chamfering mechanism 5 drives the top plate 801 to limit and fix the lever 2 in the work station 104. Since the back chamfering cutter head 501 moves to the position of the lever 2 under the control of the driver, the chamfering work on the reverse side of the work is completed. After the reverse chamfering is completed, the back chamfering cutter head 501 is reset and the limit cylinder 8 in the reverse chamfering mechanism 5 drives the top plate 801 to reset. Then the motor 101 drives the indexing table 103 to move to the position of the front chamfering mechanism 4 through the rotor 102 until the lever 2 reaches the bottom of the front chamfering mechanism 4. At this time, the limit cylinder 8 in the front chamfering mechanism 4 drives the top plate 801 to limit the work top in the work station 104, and then the driver drives and controls the downward pressure cylinder 402. The front chamfering cutter head 404 is driven to chamfer the front side of the lever 2 in a rotating state. After the front chamfering is completed, the front chamfering cutter head 404 and the limit cylinder 8 are driven to reset accordingly. The motor 101 drives the lever 2 that has completed double-sided chamfering to reach the position of the unloading mechanism 7. At this time, the unloading cylinder 703 drives the base 705 on the sliding rod 704 to move in the working direction until the base 705 reaches the position directly above the lever 2 and stops working. Then the pulling cylinder 706 drives the pull rod 707 downward until the pull rod 707 is inserted into the work. The unloading cylinder 703 works again to drive the sliding rod 704 to work and drive the pull rod 707 on the base 705 and the lever 2 to disengage from the work station 104. The lever 2 that has disengaged from the work station 104 arrives On the conveyor belt 702, the material leaves the workbench 1 driven by the conveyor belt 702, is collected and processed by the staff, and then is fed for the second time by the feeding mechanism 3, and the chamfering operation is performed in sequence, and the chamfering operation of multiple groups of levers 2 is performed in a reciprocating and orderly manner. By sequentially arranging the feeding mechanism 3, the reverse chamfering mechanism 5, the front chamfering mechanism 4 and the unloading mechanism 7 on the circumference of the rotatable indexing table 103, the lever 2 enters the indexing table 103 from the silo 302 in a semi-automatic manner, and then reaches the reverse chamfering and front chamfering mechanism 4 positions in sequence under the drive of the motor 101, and the corresponding tool head is controlled by the corresponding program to perform chamfering operation on the surface of the lever 2, and finally the unloading cylinder 703 and the pulling cylinder 706 cooperate with each other.The lever 2 is separated from the workstation 104 and reaches the position of the conveyor belt 702, and finally collected and processed uniformly. Compared with the conventional method of manually chamfering the surface of the lever 2 by the staff, the utility model realizes the automatic chamfering operation of the lever, liberating the labor intensity of the staff. The lever processed by the utility model has good quality. The overall structure of the technical solution adopted by the utility model is compact and easy for the staff to install and maintain.

[0022] Example 1

[0023] like Figure 1-3 As shown, the front chamfering mechanism 4 includes a bracket 401, a downward pressure cylinder 402 is fixedly connected to the bracket 401, a telescopic rod 403 is slidably connected in the downward pressure cylinder 402, and the end of the telescopic rod 403 is rotatably connected to a front chamfering cutter head 404, and the reverse chamfering mechanism 5 includes a back chamfering cutter head 501, and the back chamfering cutter head 501 is rotatably connected to the workbench 1 and the back chamfering cutter head 501 can be moved up and down on the workbench 1.

[0024] The effect achieved by the entire embodiment 1 is that, during use, the telescopic rod 403 in the downward-pressing cylinder 402 drives the front chamfering cutter head 404 in a rotating state to move toward the lever 2, and the lever 2 is chamfered according to the instructions of the control program. The back chamfering cutter head 501 can also slide up and down on the workbench 1 in a moving state.

[0025] Working principle: The touch control screen sends work instructions to the relevant mechanisms on the workbench. First, the loading mechanism starts working, and the feeding cylinder drives the slide rod to drive the push plate to work. The push plate enters the hopper and pushes out the lever in the hopper. After being pushed out, the lever enters the workstation position in the indexing table. At this time, the indexing table is in a stationary state. After the workstation receives the filling of the hopper, the motor cooperates with the rotor to drive the indexing table to rotate. Both the motor and the feeding cylinder work intermittently. The lever on the workstation moves to the position of the reverse chamfering mechanism under the drive of the motor and the rotor. The limit cylinder in the reverse chamfering mechanism drives the top plate to limit and fix the lever in the workstation. Since the back chamfering cutter head moves to the lever position under the control of the driver program, the chamfering work on the reverse side of the work is completed. After the reverse chamfering is completed, the back chamfering cutter head is reset and the limit cylinder in the reverse chamfering mechanism drives the top plate to reset. Then the motor drives the indexing table to move to the position of the front chamfering mechanism through the rotor until the lever reaches the positive position. At this time, the limit cylinder in the front chamfering mechanism below the surface chamfering mechanism drives the top plate to limit the working top in the work station, and then the driver drives the downward pressure cylinder to drive the rotating front chamfering cutter head to chamfer the front side of the lever. After the front chamfering is completed, the corresponding front chamfering cutter head and the limit cylinder are reset, and the motor drives the lever that has completed double-sided chamfering to reach the position of the unloading mechanism. At this time, the unloading cylinder drives the base on the sliding rod to move in the working direction until the base reaches the position directly above the lever and stops working. Then the pulling cylinder drives the pull rod downward until the pull rod is inserted into the work. The unloading cylinder works again to drive the sliding rod to drive the pull rod and the lever on the base to detach from the work station. The lever detached from the work station arrives on the conveyor belt and leaves the workbench driven by the conveyor belt. It is collected and processed by the staff, and then the loading mechanism performs secondary feeding, and the chamfering operation is performed in sequence. The chamfering operation of multiple groups of levers is performed in a reciprocating and orderly manner.
