[0054] The working principle of the present invention is:

[0055] Before drilling, the worker mounts the workpiece 8 on the jaws 63 of the jaw cylinder 62, and the jaw cylinder 62 drives the multiple jaws 63 to close, thereby clamping the workpiece 8. In addition, the worker rotates the clutch handle 462 in the positive direction, and the push rod 461 pushes the clutch rotating wheel 45 to slide rightward, and the transmission shaft hole 452 is sleeved on the driven block 410, and the clutch rotating wheel 45 is in transmission cooperation with the rotating shaft 41.

[0056] Then, the main motor 2 of the present invention starts to start, and the main motor 2 drives the first pulley to rotate. The first pulley drives the first driven pulley 22 and the second driven pulley 25 to rotate through the first belt 23 and the second belt 24, respectively, thereby driving the reducer 44 and the rotating main shaft 50 to rotate. Then, the first sprocket 26 at the output end of the reducer 44 drives the second sprocket 29 to rotate through the chain, thereby driving the rotating shaft 41 and the lifting cam 42 thereon to rotate. Under the action of the spring 411, the lifting follower wheel 43 will rise and fall with the rotation of the lifting cam 42, and the lifting cam 42 will drive the lifting follower wheel 43 to descend, thereby driving the lifting seat 40 to descend, and the gear seat 54, the rotating driven shaft 51, the multiple drill bit fixing shafts 55 and the multiple drill bits 56 on the lifting seat 40 will also descend. At the same time, the rotating main shaft 50 drives the rotating driven shaft 51 to rotate. During the descending process of the rotating driven shaft 51, it still cooperates with the rotating main shaft 50 in rotation transmission. The driving gear 52 at the lower end of the rotating driven shaft 51 drives the multiple driven gears 53 to rotate, thereby driving the multiple drill bit fixing shafts 55 and the multiple drill bits 56 thereon to rotate, so that the multiple drill bits 56 rotate and drill holes while descending. The multiple drill bits 56 start drilling holes on the end surface of the workpiece 8. When the lifting base 40 descends to the lowest point, the multiple drill bits 56 have already drilled the group of holes 81.

[0057] After that, the lifting cam 42 continues to rotate, and the lifting follower wheel 43 begins to roll toward the nearest point of the contour of the lifting cam 42. The lifting follower wheel 43 rises under the action of the spring 411, and the lifting seat 40 and the plurality of drill bits 56 also rise, and the plurality of drill bits 56 are always rotating. When the lifting seat 40 rises to the highest point, the plurality of drill bits 56 have completely separated from the workpiece 8 and rise above the workpiece 8.

[0058] During the process of the lifting seat 40 and the multiple drill bits 56 rising, the workpiece 8 rotates and the servo motor 3 starts to drive the turntable 61, the clamping cylinder 62 and the workpiece 8 to rotate to a set angle. After that, the lifting cam 42 drives the lifting seat 40 and the multiple drill bits 56 to descend again, and then continue to drill a group of holes on the end face of the workpiece 8, until a circle of holes on the end face of the workpiece 8 is drilled, and the drilling work of the workpiece 8 is completed.

[0059] When the worker wants to drill the next workpiece 8, after the multiple drill bits 56 rise and detach from the workpiece 8, the worker controls the clamping cylinder 62 to release the workpiece 8 with a hole drilled, and the worker or the manipulator quickly takes away the workpiece 8 with a hole drilled, and puts the next workpiece 8 to be drilled on the clamping claw of the clamping claw cylinder 62, and then the clamping claw cylinder 62 clamps the workpiece 8 and waits for drilling. The workpiece described in the present invention is the front load block of the ultrasonic welding gun.

[0060] When the worker needs to debug the machine, for example, to adjust the drilling depth of the drill bit, the worker reversely rotates the clutch handle 462 after the multiple drill bits 56 rise and separate from the workpiece 8, and the push rod 461 pushes the clutch rotating wheel 45 to slide to the left, the transmission shaft hole 452 separates from the driven block 410, the clutch rotating wheel 45 separates from the rotating shaft 41, and the clutch rotating wheel 45 idles. Therefore, the rotating shaft stops rotating, the lifting cam 42 also stops rotating, the lifting seat 40 and the multiple drill bits 56 also stop rising, and the worker can then rotate the manual lifting handle 7, the manual lifting gear 71 drives the driven gear 47 to rotate, and then drives the rotating shaft 41 and the lifting cam to rotate, thereby driving the lifting seat and the drill bit to rise and fall, and realizing manual debugging of the drilling depth of the multiple drill bits.
