The first pivot 5 of second bevel gear 4 up end fixedly connected with, the one end that second bevel gear 4 was kept away from to first pivot 5 runs through fixedly connected with first gear 6, and first pivot 5 runs through and connects on the roof of workstation 1 in the spacing rotation behind first gear 6.

The first gear 6 is in meshing connection with a second gear 7. The second rotating shaft 8 is fixedly connected to the center of the second gear 7, and one end, far away from the second gear 7, of the second rotating shaft 8 is connected to the top plate of the workbench 1 in a limiting and rotating mode.

Four evenly distributed holes are formed in the second gear 7, the air cylinders 9 are fixedly arranged on the upper end faces of the holes of the second gear 7, piston rods of the four air cylinders 9 penetrate through the holes and then are fixedly connected with the second motors 10, and motor shafts of the four second motors 10 are fixedly connected with the first blades 11, the second blades 19, the third blades 20 and the fourth blades 21 respectively.

The chuck shell 12 is provided with a hole at the center, and a special-shaped convex part and two sliding rods 14 are fixedly arranged inside the chuck shell 12.

One end of the threaded rod 13 far away from the first bevel gear 3 penetrates into the chuck shell 12 and then is rotatably connected in the special-shaped boss. The threaded rod 13 is threaded with a first slide 16 in the portion of the chuck housing 12.

The two sliding rods 14 are both connected with second sliding blocks 17 in a sliding manner, and the two second sliding blocks 17 and the first sliding blocks 16 are uniformly distributed in the chuck shell 12.

The third gear 15 is rotatably arranged at the central position inside the chuck shell 12 in a limiting manner, racks are fixedly arranged on the side walls, facing the third gear 15, of the first sliding block 16 and the second sliding block 17, and the racks on the first sliding block 16 and the second sliding block 17 are meshed with the third gear 15.

The first slider 16 and the second slider 17 are in limited sliding connection with the inner bottom plate of the chuck shell.

Three same T-shaped holes are uniformly formed in the top of the chuck shell 12, clamping jaws 18 are arranged in the three T-shaped holes in a limiting sliding mode, and protruding portions are arranged at the bottoms of the three clamping jaws 18.

The top of the first sliding block 16 and the top of the second sliding block 17 are both provided with a chute. The convex part on one of the jaws 18 is in sliding fit with the inclined groove on the first slide block 16, and the convex parts on the other two jaws 18 are in sliding fit with the inclined grooves on the corresponding second slide blocks 17.

Screws with different sizes are placed in the center positions of the three clamping jaws 18, the first motor 2 is started, the threaded rod 13 drives the first sliding block 16 to move, the third gear 15 drives the two second sliding blocks 17 to move, and finally the three clamping jaws 18 are driven to move towards the center position of the chuck shell 12, so that the screws with different sizes are clamped and fixed;

after the first motor 2 is started, the second bevel gear 4 and the first gear 6 are driven to rotate through the first bevel gear 3, the air cylinder 9, the second motor 10 and the blade synchronously rotate, and finally after the screw is fixed, the blade matched with the screw also rotates right above the screw, so that the requirements of replacing the blade by screws of different sizes are met, and the blade can be automatically replaced without manual operation.

The working principle is as follows:

the device can punch grooves on a first screw, a second screw, a third screw and a fourth screw from small to large, and blades matched with the first screw, the second screw, the third screw and the fourth screw are a first blade 11, a second blade 19, a third blade 20 and a fourth blade 21 in sequence.

As shown in fig. 3, a fourth screw is placed at the center of the three jaws 18, the first motor 2 is started, the first bevel gear 3 and the threaded rod 13 rotate to drive the first slider 16 to move towards the first motor 2, the first slider 16 drives the third gear 15 to rotate counterclockwise through the rack of the first slider 16, and then the two second sliders 17 are driven to move along the rotation direction of the third gear 15.

Since the jaws 18 are mounted in T-shaped holes in the chuck housing 12, the first slider 16 and the second slider 17 move the three jaws 18 toward or away from the center of the chuck housing 12 through their angled slots.

When the threaded rod 13 rotates, the first slider 16 slides a certain distance and drives one of the jaws 18 towards the fourth screw. The first sliding block 16 drives the third gear 15 to rotate, so as to drive the other two second sliding blocks 17 to slide, and the other two second sliding blocks 17 respectively drive the other two claws 18 to move towards the fourth screw. So that the three jaws 18 clamp the fourth screw in place.

Thereafter, the first motor 2 is turned off and the fourth screw is started to be punched.

And starting the air cylinder 9 corresponding to the fourth blade 21, extending downwards, and driving the fourth blade 21 to downwards punch a straight groove on the fourth screw. When a cross groove needs to be punched on the fourth screw, the adjusting cylinder 9 contracts upwards, the fourth blade 21 moves upwards to be separated from the screw, the second motor 10 is started to enable the fourth blade 21 to rotate 90 degrees, then the second motor 10 is turned off, the adjusting cylinder 9 extends downwards, and the fourth blade 21 punches the fourth screw to form the cross groove.

After the fourth screw is punched out, the cylinder 9 is adjusted to restore the fourth blade 21 to the original height, and then the cylinder 9 is turned off.

When the first motor 2 is restarted, the first bevel gear 3 and the threaded rod 13 rotate reversely, the first sliding block 16 and the second sliding block 17 move reversely, and then the three jaws 18 move away from the center of the chuck shell 12.

When the threaded rod 13 is rotated in the reverse direction, the fourth screw is loosened and the pawl 18 returns to the initial position.

When the first bevel gear 3 also rotates reversely, the second gear 7 is driven to rotate reversely, and the cylinder 9, the second motor 10 and the fourth blade 21 are restored to the initial positions.

And finally, the first motor 2 is turned off to finish the tooth-punching groove work of the fourth screw.

When the screws with other sizes are processed into the grooves, the operation can be carried out according to the groove punching process of the fourth screw.

In this embodiment, the first motor 2 rotates to drive the first slider 16 to move, so as to drive the jaws 18 to tighten screws of different sizes, thereby having a smaller transmission ratio. Meanwhile, the first motor 2 drives the second gear 7 to rotate by different angles through the first bevel gear 3, the second bevel gear 4 and the first gear 6, so that cutters at different positions on the second gear 7 correspond to screws with different sizes. In order to meet the requirements, the sizes of the first bevel gear 3, the second bevel gear 4, the first gear 6 and the second gear 7 can be adjusted, so that the transmission ratio formed by the first bevel gear 3 and the second gear 7 is smaller and is matched with the distance for the first motor 2 to drive the jaws 18 to move.

Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
