[0026] The upper surface of the slide seat 12 is welded with a first clamping plate 16. A chute 15 is opened on one side of the first clamping plate 16. A second clamping plate 17 is slidably connected in the chute 15. A threaded hole is opened on the upper surface of the slide seat 12. A lead screw 14 is threadedly connected in the threaded hole. The top end of the lead screw 14 passes through the second clamping plate 17 and is welded with a baffle.
[0027] Move the plurality of slide seats 12 along the plurality of slide rails 10 respectively. When the slide seat 12 moves to a suitable position, place the cam on the plurality of slide seats 12. Then move the plurality of slide seats 12 along the plurality of slide rails 10 again so that the first clamping plate 16 on the slide seat 12 contacts the cam. Then the insertion assembly fixes the slide seat 12, so that the first clamping plate 16 clamps the cam flatly. Then rotate the lead screw 14 to make the lead screw 14 move into the threaded hole. At this time, the lead screw 14 drives the second clamping plate 17 to move downward along the chute 15 through the baffle, so that the second clamping plate 17 clamps and limits the cam up and down in cooperation with the slide seat 12. Then punch the cam through the drilling device 2, so as to prevent the cam from moving during the punching process and avoid punching deviation.
[0028] The insertion assembly includes two pins 13. Two sliding holes penetrating through the sliding seat 12 are formed on the upper surface of the sliding seat 12. The two pins 13 are respectively inserted into the two sliding holes. On the upper surface of the bottom plate 1, a plurality of second pin openings 9 are formed at positions on both sides of the plurality of sliding rails 10, and the pins 13 are inserted into the second pin openings 9 to fix the position of the sliding seat 12 by inserting the pins 13 into the corresponding second pin openings 9.
[0029] In the utility model, the adjusting assembly includes a base 6. A dovetail groove is formed on one side of the bottom plate 1. The base 6 is slidably connected in the dovetail groove. A hydraulic cylinder 5 is fixed on the upper surface of the base 6 by bolts. One end of the hydraulic rod of the hydraulic cylinder 5 is fixed with a sliding sleeve 20 by bolts. A sliding rod 3 is slidably connected in the sliding sleeve 20. The drilling device 2 is fixed to the sliding rod 3. A driving assembly for moving the sliding rod 3 is arranged in the sliding sleeve 20. A fixing assembly for limiting the base 6 is arranged on the upper surface of the bottom plate 1.
[0030] The driving assembly includes a threaded port. The threaded port is formed on one side of the sliding sleeve 20. A threaded rod 19 is threadedly connected in the threaded port, and the threaded rod 19 is rotatably connected to the sliding rod 3.
[0031] The fixing assembly includes a plurality of first pin openings 7. The plurality of first pin openings 7 are all formed on the upper surface of the bottom plate 1 near the bottom plate 1. A bayonet is formed on the upper surface of the base 6. A U-shaped rod is clamped in the bayonet, and the U-shaped rod is clamped with the first pin opening 7.
[0032] Pull the base 6 to move along the dovetail groove. The base 6 will drive the sliding sleeve 20 to move through the hydraulic cylinder 5. The sliding sleeve 20 will drive the sliding rod 3 to move. The sliding rod 3 will drive the drilling device 2 to move. Then, the U-shaped rod is clamped into the bayonet and the first pin opening 7 to fix the position of the base 6, thereby fixing the position of the drilling device 2. At the same time, the position of the drilling device 2 can be adjusted by rotating the threaded rod 19 to drive the sliding rod 3 to move inside or outside the sliding sleeve 20.

[0033] Two first guide rods 4 are fixed on the upper surface of the base 6 by bolts. The two first guide rods 4 both pass through the sliding sleeve 20. Two second guide rods 11 are welded on the upper surface of the sliding seat 12, and the second guide rods 11 pass through the second clamping plate 17. Two rubber pads 18 are bonded to the upper surface of the sliding seat 12 and the bottom of the second clamping plate 17. The rubber pads 18 can prevent the second clamping plate 17 and the sliding seat 12 from damaging the surface of the cam when the second clamping plate 17 and the sliding seat 12 clamp the cam, improving the safety of clamping the cam.
[0034] Working principle: When in use, move multiple slide seats 12 along multiple slide rails 10 respectively. After the slide seats 12 are moved to appropriate positions, place the cams on the multiple slide seats 12, and then move the multiple slide seats 12 along the multiple slide rails 10 again so that the first clamping plates 16 on the slide seats 12 contact the cams. Then insert the pins 13 into the corresponding second pin holes 9 to fix the positions of the slide seats 12, so that the first clamping plates 16 clamp the cams in a planar manner. Then rotate the lead screw 14 to make the lead screw 14 move into the threaded holes. At this time, the lead screw 14 will drive the second clamping plate 17 to move downward along the chute 15 through the baffle, so that the second clamping plate 17 clamps and limits the cams up and down in cooperation with the slide seats 12. Then use the drilling device 2 to drill the cams, which can prevent the cams from moving during the drilling process, avoid drilling deviations, and improve the accuracy of the drilling device.
