[0021] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0022] This application discloses a device for cutting the outer tube of a motorcycle shock absorber. For example... Figure 1 As shown, the device includes a workbench 1, on which a cutting machine 2 is mounted. V-shaped plates 3 are mounted on both sides of the workbench 1 of the cutting machine 2. The V-shaped design can automatically align with outer tubes of different diameters. The inner wall of the V-shaped plate 3 is provided with anti-slip texture. The surface of the V-shaped plate 3 is coated with a layer of hard alloy to improve wear resistance. A scale is provided on the front side of the V-shaped plate 3. A lifting plate 4 is provided above both V-shaped plates 3.

[0023] See Figure 1 , Figure 4 As shown, a lifting mechanism is provided between the lifting plate 4 and the worktable 1. The lifting mechanism includes lead screws 11. Multiple lead screws 11 are provided and are symmetrically arranged on both sides of the lifting plate 4. The two ends of the lead screws 11 are rotatably connected to the worktable 1. The lead screws 11 are vertically arranged. There are four lead screws 11, which are located at the four corners of the lifting plate 4. The lead screws 11 are threadedly connected to the lifting plate 4. A worm gear 12 is provided at the lower end of the lead screw 11, and a worm 13 is provided on one side of the worm gear 12.

[0024] See Figure 1 , Figure 4 As shown, the worm gear 13 on the same side is fixedly connected by the drive rod 14. The drive rod 14 is rotatably mounted on the worktable 1. One end of one of the drive rods 14 is equipped with a servo motor, which is mounted on the bottom of the worktable 1. A transmission rod 15 is provided between the two drive rods 14. The transmission rod 15 is rotatably mounted on the worktable 1. Both ends of the transmission rod 15 and the drive rod 14 are equipped with bevel gears 16. The bevel gears 16 on the transmission rod 15 mesh with the bevel gears 16 on the drive rod 14. Through the mutual cooperation between the bevel gears 16 and the transmission rod 15, the two drive rods 14 can rotate synchronously.

[0025] See Figure 1 , Figure 2 As shown, multiple V-shaped blocks 5 are arranged between the V-shaped plate 3 and the lifting plate 4. An adjustment assembly is arranged between the V-shaped blocks 5 and the lifting plate 4. The adjustment assembly includes a screw 6, which is rotatably mounted on the lifting plate 4. The screw 6 is threadedly connected to one of the V-shaped blocks 5 and is slidably arranged with the other V-shaped blocks 5.

[0026] See Figure 2 , Figure 3 As shown, an elastic element is provided between two adjacent V-shaped blocks 5. The elastic element includes a spring 7, which is sleeved on the screw 6. The two ends of the spring 7 are fixedly connected to the two adjacent V-shaped blocks 5. A fixing element is provided between the V-shaped blocks 5 and the lifting plate 4. The fixing element includes a fixing rod 8, one end of which is installed on the V-shaped block 5. A sliding groove 10 is provided on the lifting plate 4.

[0027] See Figure 2 , Figure 3 As shown, one end of the fixing rod 8 passes through the slide groove 10. A fastening handle 9 is provided on the fixing rod 8. The fastening handle 9 is threadedly connected to the fixing rod 8. By driving the fastening handle 9 to rotate on the fixing rod 8, the fastening handle 9 moves towards the lifting plate 4, thereby fixing the corresponding V-block 5. By driving the fastening handle 9 to rotate in the opposite direction, the fixing of the V-block 5 is released.

[0028] The implementation principle of the motorcycle shock absorber outer tube cutting device in this embodiment is as follows: When it is necessary to adjust the distance between V-blocks 5 according to the size of the shock absorber outer tube, the operator first drives the fastening handle 9 to rotate, releasing the fixation of the V-blocks 5, leaving the fastening handle 9 on the V-shaped plate 3 away from the threaded end connected to the screw 6 stationary. Then, the screw 6 is driven to rotate, and the screw 6 drives one end of the V-block 5 to move. The V-block 5 moves the adjacent V-block 5 through the spring 7, thereby achieving equidistant adjustment between the V-blocks 5. After the adjustment is completed, the shock absorber outer tube is cut from the V-block 5 to the V-shaped plate 3. The plate passes between plates 3; then the servo motor is started, and the servo motor drives one of the drive rods 14 to rotate. The drive rod 14 drives the transmission rod 15 to rotate through the meshing of the bevel gears 16. The transmission rod 15 drives the other drive rod 14 to rotate. The two drive rods 14 drive the corresponding worm gear 13 to rotate. The worm gear 13 drives the worm wheel 12 to rotate. The worm wheel 12 drives the lead screw 11 to rotate. The lead screw 11 drives the lifting plate 4 to move downward. The lifting plate 4 drives the V-block 5 to move downward and cooperates with the V-block 3 to clamp the outer cylinder of the shock absorber. After fixing, the outer cylinder of the shock absorber is cut by the cutting machine 2.

[0029] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
