A delay ring 504 is fixedly connected to one side of the delay cylinder 501 away from the eccentric disc 3, and a gap is arranged between adjacent delay rings 504. The delay rings 504 are radially notched 13.

Referring to fig. 2, rollers 14 passing through the notches 13 are fixedly connected to bottom ends of two connecting plates 11 on the telescopic arm 403 near the fixed column 7, and the diameter of each roller 14 is smaller than the linear distance between the adjacent delay rings 504, and each roller 14 rolls on the sliding surface and abuts against the delay ring 504. In addition, a speed limiting groove 505 is formed between the innermost delay ring 504 and the fixed column 7 on the sliding surface, and the roller 14 is clamped into the speed limiting groove 505.

The water drop-shaped eccentric block 301 with the mass larger than that of the eccentric disc 3 is fixedly embedded on the eccentric disc 3, the fixed column 7 is fixedly connected to the eccentric block 301, and the center line of the eccentric block 301 passes through the center of the circle of the fixed column 7, so that the center of gravity of the eccentric disc 3 is offset to the side with the larger occupied ratio of the eccentric block 301.

One side of the delay cylinders 501 close to the eccentric disc 3 is fixedly connected with toothed rings, the diameters of the toothed rings are different, and the diameters of the toothed rings are gradually reduced in a direction close to the chassis 6. The inner wall of the main disc 1 is provided with inner teeth 103, the eccentric disc 3 and the eccentric block 301 are provided with a plurality of gears 15 with the same number as that of the toothed rings, the diameters and the heights of the plurality of gears 15 are different, and each gear 15 is respectively meshed with the inner teeth 103 and the corresponding toothed ring. So that the main disc 1 can drive the delay cylinder 501 at the corresponding position to rotate through the cooperation of the gear 15 and the toothed ring after rotating. In addition, several gears 15 are located on the eccentric disc 3 on the side of the eccentric mass 301 that is relatively large.

The principle of implementation of the embodiment of the application is that, before use, the chuck 404 is pulled up by the pull groove so that the chuck 404 is flush with the cartridge 2. At this time, the telescopic arm 403 is extended to deform the return spring 402 until the roller 14 extends into the speed limiting groove 505 and abuts against the inner wall of the speed limiting groove 505. Next, the cartridge 2 is fitted over the chuck 404 and mounted on the main tray 1, and then the chassis 6 is mounted on the machine tool.

It should be noted that, one side of the machine tool is provided with a synchronously rotating extrusion member, which slides toward the tubular member 2 and extrudes one end of the tubular member 2 facing away from the main disc 1, so that the tubular member 2 is fastened between the main disc 1 and the extrusion member.

The machine tool drives the main disc 1 to rotate, and the barrel 2 arranged on the main disc 1 synchronously rotates. In addition, the main disc 1 drives the supporting rod 405 to rotate, the supporting rod 405 drives the chuck 404 to rotate, and the chuck 404 can drive the barrel 2 and the telescopic arm 403 to synchronously rotate.

When the telescopic arm 403 rotates, under the influence of centrifugal force, the roller 14 rolls out of the speed limiting groove 505 and abuts against the innermost delay ring 504.

At this time, the angle between the two connection plates 11 at the bottom of the telescopic arm 403 becomes larger, and the telescopic arm 403 is contracted according to the characteristics of quadrilateral variability, so that the chuck 404 is further slid inwards. At this point, the turning insert extension turns the cartridge 2 along the outer surface of the chuck 404.

Meanwhile, after the main disk 1 rotates, a plurality of delay drums 501 are driven to rotate through the gear 15, and the rotation speed of each delay drum 501 is different due to the fact that the diameters of the gear 15 and the toothed ring for driving the delay drums 501 to rotate are different. The roller 14 continues to squeeze the innermost delay ring 504 under centrifugal force and return spring 402.

The innermost delay ring 504 rotates under the action of the delay cylinder 501, so that when the notch 13 on the delay ring 504 rotates to the position of the roller 14, the roller 14 rapidly slides to the delay ring 504 on the next layer along the notch 13 under the action of centrifugal force and the return spring 402 and collides with the delay ring 504 on the next layer. And the rotation speed of the delay ring 504 of the layer is different from that of the delay ring 504 of the innermost layer, so that the notch 13 of the layer is dislocated from the notch 13 of the innermost layer, and the roller 14 cannot directly run through the delay ring 504 of the layer.

The roller 14 passes through the notches 13 of the delay rings 504 of different layers for a plurality of times according to the above process until the roller 14 collides with the delay ring 504 of the outermost layer.

At the same time, the telescopic arm 403 is retracted inwardly a distance such that the support rod 405 is retracted inwardly a distance in synchronization with the chuck 404, and the cartridge 2 is turned. Meanwhile, each time the roller 14 reaches a layer of delay ring 504, the telescopic arm 403, the chuck 404 and the support rod 405 correspondingly shrink for a certain distance, so that the cylinder 2 can continuously support the turned part of the cylinder 2 during turning.

When the main disk 1 drives the gears 15, the gears 15 are densely arranged on the eccentric disk 3, and the eccentric blocks 301 occupy a relatively large area. The main disk 1 applies thrust forces in all directions to the plurality of gears 15, and most of rotation is the rotation force of the gears 15, so that the eccentric disk 3 and the gears 15 can be kept as motionless as possible when the main disk 1 rotates.

Similarly, when the roller 14 rolls gradually onto the outermost time delay ring 504, the chuck 404, the telescopic arm 403, and the support rod 405 retract into the main disk 1, and the outer side of the chuck 404 is flush with the main disk 1. After retraction, the cartridge 2 lacks support to drop out naturally.

The embodiments of the present application are all preferred embodiments of the present application, and are not intended to limit the scope of the present application, wherein like reference numerals are used to refer to like elements throughout. Therefore, all equivalent changes according to the structure, shape and principle of the present application should be covered in the protection scope of the present application.
