[0036] The lifting device 3 includes a fine-tuning device 9, a lifting cylinder 10 fixed on the fine-tuning device 9, and a lifting plate 11 connected to the travel rod of the lifting cylinder 10. The lifting cylinder 10 drives the lifting plate 11 to move up and down, and the positioning mold 6 is fixed on the lifting plate 11.

[0037] The positioning mold 6 is in an inverted “T”-shaped structure, and a “T”-shaped slot 12 is provided at the center of the positioning mold 6 .

[0038] The fine-tuning device 9 includes a fine-tuning plate 13 and a fine-tuning structure 14. The fine-tuning plate 13 is moved up and down along the moving direction of the positioning mold 6 by the fine-tuning structure 14. In fact, the fine-tuning structure 14 is similar to a worm gear mechanism.

[0039] The bottom surface of the positioning plate 8 is provided with a positioning groove 15 .

[0040] The rotating device 4 includes a driving cylinder 16, a reducer 17 and a driving plate 18. The driving cylinder 16 can drive the driving plate 18 to move up and down. The reducer 17 is provided with an output shaft 19; the output shaft 19 passes through a bearing 20 provided on the driving plate 18 and extends to the bottom of the driving plate 18, and the rotating mold 7 is fixed to the lower end of the output shaft 19; the rotating mold 7 is driven by the reducer 17 to rotate around its own axis; the output shaft 19 can move up and down along its own axis along with the driving plate 18.

[0041] The clamping device 5 includes a base 21, a clamping cylinder 22 fixed on the base 21, a driving block 23 connected to the stroke rod of the clamping cylinder 22, two clamping blocks 25 arranged in the guide groove 24 of the base 21, and a clamping arm 26 arranged on the clamping block 25. The two ends of the driving block 23 are respectively provided with driving inclined surfaces 27. The two clamping blocks 25 are respectively located on both sides of the driving block 23, and the clamping blocks 25 are provided with force inclined surfaces 28 corresponding to the driving inclined surfaces 27, and a limiting structure is provided between the clamping block 25 and the driving block 23; the driving block 23 is pushed to move by the clamping cylinder 22, so that the driving inclined surface 27 squeezes the force inclined surfaces 28 of the two clamping blocks 25, so that the two clamping blocks 25 are synchronously translated left and right in the guide groove 24, and then the two clamping arms 26 are brought together or opened.

[0042] The guide groove 24 is a T-shaped groove, and the clamping block 25 is provided with a T-shaped block 29 corresponding to the T-shaped groove.

[0043] The limiting structure includes a T-shaped sliding groove 30 arranged on the driving inclined surface 27 and a T-shaped sliding block 31 arranged on the force-bearing inclined surface 28 of the clamping block and corresponding to the T-shaped sliding groove 30 .

[0044] The working principle of the shock absorber rotating device of the present invention is explained below:

[0045] When the shock absorber rotating device of the present invention is in use, the shock absorbing body 32 of the shock absorber 50 is placed on the lifting device 3. Specifically, the lower end of the shock absorbing body 32 is clamped in the "T"-shaped clamping groove 12 of the positioning mold 6, and the spring 33 on the shock absorbing body 32 is located below the positioning plate 8 and faces the positioning groove 15 on the bottom surface of the positioning plate 8. Then, the lifting cylinder 10 pushes the positioning mold 6 to move upward, so that the upper end of the spring 33 abuts against the positioning groove 15. Then, the lifting cylinder 10 stops working. At this time, the nut head 34 on the shock absorbing body 32 reaches the position of the clamping device 5, and the two clamping arms 26 of the clamping device 5 are in an open state. Then, the clamping cylinder 22 of the clamping device 5 causes the driving block 23 to move backward. Since a limiting structure is provided between the driving block 23 and the clamping block 25, and the clamping block 25 is arranged in the guide groove 24, the driving block 23 drives the two clamping blocks 2 5 move towards each other and get close to each other, thereby clamping the nut head 34 and fixing the shock absorbing body 32. During this process, the T-shaped slider 31 on the force-bearing inclined surface 28 of the clamping block 25 moves obliquely in the T-shaped slide groove 30 on the driving inclined surface 27 of the driving block 23, and will never get out of the T-shaped slide groove 30. In addition, the T-shaped block 29 of the clamping block 25 is in the guide groove 24, so that the clamping block 25 can move towards each other in the guide groove 24, and then the clamping arm 26 clamps the nut head 34. Then the rotating device 4 works. We first place the lifting ring 35 in the rotating mold 7, and the driving cylinder 16 pushes the driving plate 18 downward, so that the lifting ring 35 in the rotating mold 7 on the driving plate 18 reaches the upper end position of the shock absorbing body 32. Finally, the reducer 17 rotates the output shaft 19, thereby driving the rotating mold 7 to rotate, and finally the lifting ring 35 is screwed with the upper end of the shock absorbing body 32.

[0046] During the operation of the rotating device 4, since the output shaft 19 and the driving plate 18 are connected by the bearing 20, the output shaft 19 and the driving plate 18 can be understood as an integrated structure. Then, when the driving cylinder 16 pushes the driving plate 18 downward, the output shaft 19 and the rotating mold 7 connected to the lower end of the output shaft 19 move downward as a whole.

[0047] The rotating mold 7 has two structural forms. The first one is: the rotating mold 7 includes a rotating body 37 with a slot 36 on the bottom surface, and two symmetrical elastic structures arranged on both sides of the rotating body 37. The elastic structure includes a positioning shaft 38, a spring 39 and a positioning block 40. The spring 39 is sleeved on the positioning shaft 38, and one end of the spring 39 abuts against the positioning pin 41 at the front end of the positioning shaft 38, and the other end abuts against the inner wall of the slot 36. The front end of the positioning pin is arc-shaped; the positioning block 40 is fixed to the rear end of the positioning shaft 38, and the positioning shaft 38 abuts against the side wall of the rotating body 37. When in use, the eyelet body 35 is inserted into the slot 36 of the rotating body 37 from bottom to top, and is squeezed by the eyelet body 35, so that the positioning shaft 38 of the elastic structure moves axially outward. When the eyelet body 35 is inserted into place, the through hole 42 on the eyelet body 35 is opposite to the two positioning shafts 38. Under the elastic force of the spring 39, the positioning shaft 38 moves axially inward to reset, and the positioning pin 41 at the front end of the positioning shaft 38 matches in the through hole 42. When the eyelet body 35 is pulled out, since the front end of the positioning pin 41 is an arc-shaped structure, the arc-shaped structure of the positioning pin 41 is the part in the through hole 42, which is squeezed by the eyelet body 35 and can be squeezed and pushed smoothly, so that the positioning shaft 38 moves axially outward, thereby smoothly removing the eyelet body 35.

[0048] The second type is: the rotating mold 7 includes a rotating body 37 with a slot 36 on the bottom surface, a pressing block 43 is provided on the inner wall of the slot 36, a guide shaft 44 is provided on the pressing block 43, and the guide shaft 44 is passed through the guide hole 45 of the rotating body 37, and an elastic driving structure for radially moving the pressing block 43 is provided in the rotating body 37, and the elastic driving structure includes an elastic hole 46 arranged on the rotating body 37, a variable spring 47 arranged in the elastic hole 46, and an adjusting screw 48 screwed in the elastic hole 46 and having an extrusion effect on the variable spring 47, and by rotating the adjusting screw 48, the extrusion force on the variable spring 47 is adjusted, thereby adjusting the elastic force of the variable spring 47 on the pressing block 43. Specifically, by adjusting the position of the screw 48 in the elastic hole 46, the squeezing force on the variable spring 47 is changed, and then the force of the pressure block 43 on the eyelet body 35 is changed, so that the pressing force of the pressure block 43 on the eyelet body 35 inserted into the slot 36 is optimized, and the eyelet body 35 can be quickly installed or removed by simply plugging and pulling out the eyelet body 35 with force.

[0049] Two limit plates 49 symmetrically arranged and distributed along the radial direction are further disposed in the slot 36 , and the two limit plates 49 are bakelite boards.

[0050] A fine-tuning device 9 is also provided under the lifting device 3 of the present invention. Since the shock absorber 50 has various specifications, the lifting device 3 has various sizes of upward displacement of the shock absorbing body 32. In order to improve stability, we use a lifting cylinder 10 with a uniform stroke. For shock absorbing bodies 32 of different sizes, we use a fine-tuning device 9 to ensure that the lifting cylinder 10 can lift and lower the shock absorbing body 32 into place. Specifically, the fine-tuning structure 14 is manually adjusted to make the fine-tuning plate 13 move up and down along the moving direction of the positioning mold 6.

[0051] The above is a detailed introduction to the shock absorber rotational installation device provided in the embodiment of the present invention. Specific examples are used in this article to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand the technical solutions disclosed by the present invention. At the same time, for those skilled in the art, according to the ideas of the present invention, there will be changes in the specific implementation methods and application scopes. In summary, the content of this specification should not be understood as a limitation of the present invention.
