Description

Technical Field

[0001] This invention relates to an outer tube for a motorcycle / automobile shock absorber and a cutting device for its processing. Background Technology

[0002] In recent years, with the continuous rise of the motorcycle industry both domestically and internationally, the number of people who like motorcycles and enjoy riding them has increased significantly. The demographic is also becoming younger and more individualistic, leading to a growing demand for diverse and personalized motorcycle shock absorber performance. Motorcycle shock absorbers typically consist of a shock absorber outer tube, rod core, end cap, and spring. For example, Chinese utility model patent CN219673166U describes a motorcycle front shock absorber preload adjustment mechanism, which includes a fork tube, screw plug, adjusting seat, adjusting sleeve, multiple abutment blocks, spring sleeve, shock absorber spring, assembly hole, screw hole, receiving hole, hollow piston rod, and hydraulic oil resistance adjustment assembly. By combining the torsion sleeve, adjusting seat, adjusting sleeve, abutment blocks, and spring sleeve, the compression length of the shock absorber spring is adjusted. While its structure is simple and less prone to failure, it has the following drawbacks:

[0003] 1. The outer wall of the front fork tube (shock absorber outer tube) is directly exposed to the environment and is easily damaged by external environmental factors. Even if paint is sprayed on its surface before leaving the factory to prevent rust, it is impossible to avoid the shock absorber outer tube from being damaged by collisions with foreign objects.

[0004] 2. The front fork tube (outer shock absorber tube) is a single-layer structure. When it is hit by a foreign object, it cannot effectively disperse the impact, which can easily lead to local inward denting and affect the normal sliding of the inner shock absorber tube in the inner cavity of the outer shock absorber tube. Summary of the Invention

[0005] The present invention aims to solve one of the technical problems existing in the prior art.

[0006] This application provides an outer tube for a motorcycle / automobile shock absorber, comprising:

[0025] A pair of sliding grooves are symmetrically arranged on both sides of the top of the inner peripheral wall of the clamping machine housing;

[0026] The clamping cavity is located between the inner peripheral wall of the clamping machine housing and the top surface of the machine platform. Each floating block can be floatingly inserted into the corresponding slide groove. A pair of flipping blocks can be flipped and installed in a pair of connecting sections through corresponding hinge shafts.

[0027] The linkage unit includes:

[0028] An arc-shaped slider, which can be slidably installed on the left / right side of the arc segment, with its lower end extending into the corresponding connecting segment;

[0029] A sliding groove is located at the end of the arc-shaped slider away from the connecting section;

[0030] A pair of transmission inclined slots are symmetrically arranged on the side wall of the sliding slot;

[0031] A pair of transmission sliders are symmetrically fixed to the outer wall of the floating block, and simultaneously slide in cooperation with the corresponding transmission grooves.

[0032] In each transmission spur groove, the distance between the upper end and the clamping cavity is less than the distance between the lower end and the clamping cavity.

[0033] The drive mechanism includes:

[0034] A pair of lifting housings are fixedly connected to the top of each clamping machine housing, and their inner cavities are connected to the corresponding transmission cavities.

[0035] A pair of lifting sliders, controlled by a lifting unit, can be lifted and lowered in the corresponding lifting housing;

[0036] Two pairs of swing arms, one end of each swing arm is hinged to the upper end of the corresponding arc slider, and the other end is hinged to the lower end of the corresponding lifting slider.

Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0055] The server provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0056] Example 1:

[0057] like Figure 1 As shown, this application embodiment provides an outer tube for a motorcycle / automobile shock absorber, including a tube body 101 with a paint layer on its surface; and a buffer sleeve 102, which wraps around the outside of the tube body 101.

[0058] Furthermore, it also includes an inner liner 103, which is fitted inside the cavity of the pipe body 101; a number of support blocks 104 are fixedly connected to the circumferential wall of the inner liner 103 at intervals along the circumference, and the outer ends of the support blocks 104 abut against the inner circumferential wall of the pipe body 101, forming a buffer cavity 105 between adjacent support blocks 104.

[0059] In this embodiment of the application, due to the above-described structure, the outer shock absorber inner tube can be slidably inserted into the inner cavity of the inner bushing 103. The buffer sleeve 102 is made of rubber, which can effectively absorb impact and resist scratches from foreign objects. With the further dispersion of impact by each buffer cavity 105 and the support block 104, it can be ensured that the impact force acting on the inner bushing 103 is dispersed, thereby improving the durability of the tube body 101.

[0060] Example 2:

[0061] like Figures 2 to 3 As shown, in this embodiment, a cutting device for processing the outer tube of a motorcycle shock absorber is also disclosed, which includes a machine base 201, on the top of which a liftable cutting unit 202 is installed; an assembly clamping mechanism for fixing the tube body 101 on the top of the machine base 201; and a drive mechanism 3 for driving the assembly clamping mechanism to move synchronously.

[0062] Furthermore, the clamping mechanism includes a clamping frame 4, which has a clamping cavity 41, a transmission cavity 42, a pair of floating blocks 43 and a pair of flipping blocks 44 inside; a pair of linkage units 5, which cooperate with the drive mechanism 3 to make the pair of floating blocks 43 and the pair of flipping blocks 44 simultaneously extend into / out of the clamping cavity 41. The transmission cavity 42 is arranged around the outside of the clamping cavity 41, in the shape of an inverted U, and both lower ends are connected to the transmission cavity 42.

[0063] Furthermore, it also includes a discharge port 203, which is located on the top surface of the machine base 201, below the clamping cavity 41; and several rotating rollers 204, which are rotatably mounted on the top surface of the machine base 201 near the cutting unit 202.

[0064] In this embodiment of the application, due to the above-described structure, the blank tube to be cut is fed from between each rotating roller 204 and the cutting device into the clamping cavity 41 of each clamping mechanism. Then, the drive mechanism 3, in conjunction with a pair of linkage units 5, controls each floating block 43 and each flipping block 44 to move towards the outer wall of the blank tube until the surfaces of each floating block 43 and each flipping block 44 abut against the corresponding positions of the outer peripheral wall of the blank tube. At this time, the cutting unit 202 (cutting machine) is activated, and under the action of the hydraulic cylinder or the air cylinder, the tube body 101 is cut off from the blank tube. The drive mechanism 3 is activated again, in conjunction with a pair of linkage units 5, to control each floating block 43 and each flipping block 44 to detach from the surface of the tube body 101. The pairs of flipping blocks 44 located below flip until the distance between them is greater than the diameter of the tube body 101. Under the action of gravity, the tube body 101 falls into the discharge port 203 and is discharged through the discharge port 203.

[0065] Example 3:

[0066] like Figures 2 to 3 As shown, in this embodiment, in addition to the structural features of the aforementioned embodiments, the transmission cavity 42 includes an arc segment 421, which is arranged around the outside of the clamping cavity 41; and a pair of connecting segments 422, which are used to connect the two ends of the arc segment 421 to the left and right sides of the bottom of the transmission cavity 42 respectively.

[0067] Furthermore, the clamping frame 4 includes a clamping housing 45, which is in the shape of an inverted U, with both bottom ends fixed to the top surface of the machine base 201; a pair of sliding grooves 46, symmetrically arranged on the top two sides of the inner peripheral wall of the clamping housing 45; the clamping cavity 41 is located between the inner peripheral wall of the clamping housing 45 and the top surface of the machine base 201; each floating block 43 can be floatingly inserted into the corresponding sliding groove 46; and a pair of flipping blocks 44 can be flipped and installed in a pair of connecting sections 422 through corresponding hinges.

[0068] Furthermore, the linkage unit 5 includes an arc-shaped slider 51, which is slidably mounted on the left / right side of the arc segment 421, and its lower end can extend into the corresponding connecting segment 422; a sliding groove 52, which is disposed at the end of the arc-shaped slider 51 away from the connecting segment 422; a pair of transmission inclined grooves 53, which are symmetrically disposed on the side wall of the sliding groove 52; and a pair of transmission sliders 54, which are symmetrically fixed to the outer wall of the floating block 43, and simultaneously slide in cooperation with the corresponding transmission inclined grooves 53. The distance between the upper end of each transmission inclined groove 53 and the clamping cavity 41 is less than the distance between the lower end and the clamping cavity 41.

[0069] In this embodiment of the application, due to the aforementioned structure, when the floating blocks 43 and the flipping blocks 44 need to move towards the outer surface of the tube 101, the driving device controls a pair of arc-shaped sliders 51 to slide downwards in the arc segment 421. During this process, the lower end face of each arc-shaped slider 51 abuts against the upper sidewall of the corresponding flipping block 44, causing each flipping block 44 to flip around the corresponding hinge axis towards the outer surface of the tube 101 until the sidewall of each flipping block 44, which was originally at the bottom, abuts against the outer wall of the tube 101. At this time, the arc-shaped sliders... Block 51 can continue to descend, and the flipping block 44 flips so that its original top side wall abuts against the inner side wall of the arc slider 51, to ensure that the flipping block 44 is in close contact with the surface of the tube 101. During this process, each transmission slider 54 also moves from the lower end to the upper end of the corresponding transmission groove 53, pushing the corresponding floating block 43 to slide into the clamping cavity 41 in the sliding groove 52 and the sliding groove 46. The end face of each floating block 43 extending into the clamping cavity 41 also abuts against the outer wall of the tube 101, thus completing the fixation of the tube 101.

[0070] When it is necessary to move the floating blocks 43 and the flipping blocks 44 away from the tube body 101, the drive device controls a pair of arc sliders 51 to slide upward in the arc segment 421. During this process, the lower end of each arc slider 51 gradually moves away from the corresponding flipping block 44. Under the action of gravity, each flipping block 44 flips around the corresponding hinge axis in a direction away from the outer surface of the tube body 101. Under the action of gravity, the tube body 101 can fall from the clamping cavity 41 into the discharge port 203. During this process, each transmission slider 54 also moves from the upper end to the lower end of the corresponding transmission inclined groove 53, pushing the corresponding floating block 43 to slide into the sliding groove 52, thus releasing the fixation of the tube body 101.

[0071] Example 4:

[0072] like Figures 2 to 3 As shown, in this embodiment, in addition to the structural features of the aforementioned embodiments, the drive mechanism 3 includes a pair of lifting shells 31, which are respectively fixed to the top of each clamping machine shell 45, and their inner cavities are connected to the corresponding transmission cavities 42; a pair of lifting sliders 32, which are controlled by the lifting unit 6 and can be lifted and lowered in the corresponding lifting shells 31; and two pairs of swing arms 33, one end of each swing arm 33 is hinged to the upper end of the corresponding arc slider 51, and the other end is hinged to the lower end of the corresponding lifting slider 32.

[0073] Furthermore, the lifting unit 6 includes a pair of transmission transverse grooves 61, respectively disposed on each lifting slider 32; a pair of turntables 62, respectively rotatably mounted between each lifting slider 32 and the inner wall of the corresponding lifting housing 31; a pair of push-pull sliders 63, respectively fixed to the eccentric position of each turntable 62 facing the side wall of the corresponding lifting slider 32, and slidingly engaged with the corresponding transmission transverse grooves 61; and a dual-axis motor 64, whose two output shafts are respectively connected to each turntable 62.

[0074] In this embodiment of the application, due to the above-described structure, when it is necessary to control the lifting / lowering of each arc slider 51, the dual-axis motor 64 rotates, driving each turntable 62 to rotate around its own circumference in the corresponding lifting housing 31. Each push-pull slider 63 moves together with the corresponding turntable 62, sliding left / right in the corresponding transmission transverse groove 61 and driving the corresponding lifting slider 32 to rise / fall through the corresponding transmission transverse groove 61. When the lifting slider 32 rises / falls, it pushes the corresponding arc slider 51 to rise / fall through the corresponding swing arm 33.
