A support frame 3 is mounted on the rear end of the top wall of the workbench 1. A hydraulic cylinder 4 is mounted on the top wall of the support frame 3. The output end of the hydraulic cylinder 4 passes through the top wall of the support frame 3 and is connected to a mounting base 5. A drill bit 6 is mounted on the bottom wall of the mounting base 5. A first motor 7 is mounted on the bottom wall of the workbench 1. The output end of the first motor 7 passes through the top wall of the workbench 1 and is mounted on the testing table 2. The top wall of the testing table 2 has four sets of placement slots 8 arranged in a ring shape. The fixing device is installed in each of the four sets of placement slots 8. The fixing device includes a groove body 9, a bidirectional screw 10, a slider 11, a clamping block 12, a second motor 13, a fixing frame 14, and a threaded rod. 15. A square nut 16, a fixing block 17, a third motor 18, and a V-groove 19. A groove 9 is formed on one side wall of the placement groove 8 near the center of the testing platform 2. A bidirectional screw 10 is rotatably mounted within the groove 9. A second motor 13 is mounted on one end of the bidirectional screw 10. Slider blocks 11 are threaded onto both ends of the bidirectional screw 10. Clamping blocks 12 are fixedly mounted on the side walls of the sliders 11. A fixing frame 14 with a side opening is mounted on the top wall of the testing platform 2 away from the groove 9. A threaded rod 15 is rotatably mounted within the fixing frame 14. A third motor 18 is mounted on the top end of the threaded rod 15, penetrating the top wall of the fixing frame 14. The threaded rod 15 is threaded... The square nut 16 is installed on the groove, and the fixing block 17 is fixedly installed on the side wall of the square nut 16. The inner side walls of the two sets of clamping blocks 12 and the bottom wall of the fixing block 17 are all provided with the V-groove 19. In this embodiment, the cylinder ear ring to be processed is placed in a set of placement slots 8 on the inspection table 2, and then the second motor 13 is started. The second motor 13 drives the bidirectional screw 10 to rotate, so that the two sliders 11 move relative to each other along the track in the groove 9. After adjusting to the appropriate position, it stops until the two sets of clamping blocks 12 fix the left and right ends of the cylinder ear ring. The relative movement of the two sets of clamping blocks 12 can center the position of the cylinder ear ring into the V-groove 19 of the two sets of clamping blocks 12, ensuring the consistency of the drilling position in the later stage. Then start The third motor 18 is activated, and its output drives the threaded rod 15 to rotate.
