A plurality of evenly distributed vacuum suction cups 2 are fixedly installed on the top of the placing platform 3, and a collecting inclined plate 6 is fixedly installed on the front and rear parts of one side of the frame 1. The collecting inclined plates 6 are respectively arranged directly under the grinding wheels 74 on the same side. The staff places the plate to be chamfered on the placing platform 3 and uses an external power source to control the vacuum suction cup 2. At this time, the vacuum suction cup 2 uses negative pressure to firmly adsorb the plate on the placing platform 3, and then the feeding mechanism 4 moves the fixed plate, and then cooperates with the grinding wheel 74 to grind and chamfer the plate.

[0022] The cam 73 is fixed on the workbench 74, and the cam 73 is fixed on the workbench 74. The cam 73 is fixed on the workbench 74, and the cam 73 is fixed on the workbench 74. With the cooperation of 79, the limit pin 710 will re-engage in the corresponding limit hole 75, so that the use angle of the grinding wheel 74 can be fixed. The front and rear parts of one side of the frame 1 are fixedly installed with a mounting bracket 73, and the middle part of the mounting bracket 73 is rotatably installed with a servo motor 71. The driving end of the servo motor 71 is fixedly installed with a grinding wheel 74, and the middle part of the outer periphery of the adjusting bracket 78 is movably installed on the surface of the servo motor 71 on the same side. Since corresponding gaps are provided between the frame 1, the mounting bracket 73 and the servo motor 71, the adjusting bracket 78 and the servo motor 71 are movably installed, so that the grinding wheels 74 will not interfere with each other when adjusting the angle, thereby affecting the normal use of the chamfering equipment. At the same time, grinding wheels 74 are provided on both sides of the frame 1, which can grind both sides of the plate at the same time, which is beneficial to improving the chamfering efficiency, and the two adjacent limit holes 75 are set at a certain angle, which can improve the adjustment accuracy of the grinding wheel 74 and increase the chamfering quality.

[0023] The feeding mechanism 4 includes a mounting plate 45, which is fixed on the middle of both sides of the frame 1 respectively. The mounting plates 45 are rotated and installed with a threaded rod 46 near the middle of one side.

Under the cooperation of the threads, the connecting plate 9 will drive the placement platform 3 to move along the guide rail 5. During the movement of the placement platform 3, the grinding wheels 74 on both sides of the frame 1 will chamfer both sides of the plate. Moreover, when the stepping motor 41 rotates in the opposite direction, the rotation direction of the threaded rod 46 will change, and the placement platform 3 will be reset along the guide rail 5. Then the staff will turn the plate and repeat the operation to complete the chamfering of the plate, avoiding manual feeding and the staff will not be close to the chamfering equipment, thereby improving safety.

[0024] The servo motor 71 is stopped, the stepper motor 41 is reversed, and the placement platform 3 is reset. Then, the staff turns the plate around and repeats the operation to chamfer the four sides of the plate. After the chamfering is completed, the plate can be removed from the placement platform 3.
