The first ball screw 62 is provided with guide rods 67 on the front and rear sides. The two ends of the two guide rods 67 are fixedly connected to the inner wall of the fixed column 61. The surface of the guide rod 67 is slidably connected to the cross plate 63. The upper and lower sides of the ends of the two arc plates 66 close to the fixed column 61 are fixedly connected with guide blocks 68. The ends of the guide blocks 68 close to the fixed column extend to the inside of the fixed column 61. The ends of the two arc plates 66 away from the fixed column 61 are both provided with anti-slip glue, the surface of the fixed column 61 is penetrated with a through groove for the push block 64 and the guide block 68 to move, and a sealing ring is provided inside the through groove. A rotating rod 69 is provided above the fixed column 61, and the bottom end of the rotating rod 69 penetrates the fixed column 61 and is fixedly connected to the first ball screw 62.

The design of the sealing ring can effectively isolate the coolant from entering the interior of the fixed column 61 to improve the stability of the equipment operation. The design of the guide block 68 is to improve the stability of the arc plate 66 when it moves.

[0027] When the earring part of the cylinder earring is sleeved on the fixing mechanism 6, the fixing seat 60, the fixing column 61 and the arc plate 66 play a preliminary fixing role on the cylinder earring, and then the handwheel 612 is pulled, the positioning column 614 releases the restriction on the handwheel 612, and the spring 613 is deformed by force, and then the handwheel 612 is turned, and the handwheel 612 drives the rotating rod 69 to rotate under the action of the resistance of the block 610, and then the rotating rod 69 drives the first ball screw 62 to rotate, so that the two cross plates 63 on the first ball screw 62 are close to and away from each other, and the two cross plates 63 push the two propulsion blocks 64 to move horizontally through each two driving arms 65 on the same side The two pushing blocks 64 push the two arc plates 66 towards and away from each other. When the two arc plates 66 move away from each other, they press against the inner wall of the earring. At this time, the handwheel 612 is moved downward for a certain distance, and the positioning column 614 enters the positioning groove to lock the handwheel 614. Under the action of the spring 613 restoring the deformation, the handwheel 612 is not easy to move out of the restriction of the positioning column 614, so that the two arc plates 66 no longer move, thereby achieving the fixing effect of the earring and ensuring that the earring will not deviate during the punching process. The surfaces of the two arc plates 66 are provided with anti-skid pads to achieve a better fixing effect. At the same time, the anti-skid pads are made of soft material to protect the inner wall of the earring when pressed.

A second ball screw 71 is arranged above the guide rail 70, and the surface of the second ball screw 71 is movably matched with the moving block 5. One end of the second ball screw 71 is rotatably connected to the baffle 202. A servo motor 72 is longitudinally fixedly installed on the top of the workbench 1 outside the drilling cover 2, and the output end of the servo motor 72 is connected to the second ball screw 71.

The V-shaped design of the top of the guide rail 70 allows the coolant and waste chips to effectively flow into the waste box 102 without accumulating on the guide rail 70. At the same time, the setting of the cleaning ring 501 can effectively remove the waste chips on the first ball screw 62 to ensure the normal operation of the equipment. The baffle 202 is designed to be L-shaped, which is located on the rear side of the coolant pipe 4, can effectively isolate the coolant and waste chips so that they can better enter the debris box and the height of the baffle 202 will not hinder the normal operation of the drilling platform 3.

[0029] The second ball screw 71 is driven to rotate by the servo motor 72, so that the moving block 5 can reciprocate on the guide rail 70, and then the moving block 5 drives the cylinder earring through the fixing mechanism 6 to perform positioning processing. After the processing is completed, the second ball screw 71 drives the fixing mechanism 6 and the processed cylinder earring through the moving block 5 to move away from the drilling cover 2. During the movement, it will pass through the cleaning brush 201, and the cleaning brush 201 can clean the waste chips remaining on the moving block 5, the fixing mechanism 6 and the processed earring.
