Description

Technical Field

[0001] This utility model relates to the field of shock absorber manufacturing, specifically to an adjustable positioning auxiliary structure for welding thin-walled shock absorber components. Background Technology

[0002] In the automotive and construction machinery industries, shock absorbers, as core damping components, directly impact the driving stability and service life of the equipment. Among these components, the dust cover, a critical protective element, is a typical thin-walled part. Due to the need to balance lightweight design with protective strength, its wall thickness is typically only 0.8–2 mm. It must be connected to the piston rod or cylinder via welding, such as argon arc welding or CO2 gas shielded welding, to form a sealed protective barrier. The core function of this thin-walled component is to prevent external dust, mud, rainwater, and other impurities from entering the shock absorber, thus avoiding wear on seals and contamination of hydraulic oil.

[0003] Existing welding fixtures for thin-walled parts are mostly one-to-one dedicated designs. For dust covers of thin-walled parts of different diameters, the entire assembly needs to be disassembled and the bracket or jaw assembly replaced. When changing models, multiple sets of bolts need to be loosened, the reference position adjusted, and recalibrated, which cannot meet the flexible production needs of "multiple varieties and small batches" on the production line.

[0004] Therefore, it is necessary to invent an adjustable positioning auxiliary structure for welding thin-walled shock absorber components to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide an adjustable positioning auxiliary structure for welding thin-walled shock absorber components. Through the radial synchronous adjustment system of the mounting frame-guide rod-drive component, and the height adaptation structure of the support component-positioning bolt-positioning hole, it can solve the problems in the prior art where the welding fixtures for thin-walled components are mostly one-to-one dedicated designs, require the overall disassembly and replacement of components for thin-walled components of different diameters, and require loosening multiple sets of bolts to adjust the reference and recalibrate when changing the type, which cannot adapt to the flexible production needs of "multiple varieties and small batches" of production lines.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an adjustable positioning auxiliary structure for welding thin-walled shock absorber components, comprising: The mounting frame has multiple sets of guide rods horizontally fixedly connected to its upper and lower parts. Two sets of moving parts are slidably connected to the outer side of the guide rods. A drive plate is fixedly connected to the lower part of the moving parts. The drive plate is slidably connected to the outer side of the guide rods. A drive component is rotatably connected to the bottom of the mounting frame. The drive component is threadedly connected to the inner wall of the drive plate. A handwheel is fixedly connected to the left side of the drive component. A support assembly is provided on the outside of the movable part and is used for positioning and supporting the thin-walled part. The support assembly includes multiple sets of support members, which are slidably connected to the outside of the movable part. Positioning bolts are threadedly connected to the outside of the support members. Multiple sets of positioning holes are horizontally opened on opposite sides of the two sets of movable parts. Positioning bolts are inserted into the inner walls of the positioning holes. Positioning wheels are rotatably connected to opposite sides of the multiple sets of support members.

[0007] Preferably, an auxiliary component is provided on the outside of the support component. The auxiliary component includes a fixed plate fixedly connected to the front side of the support component. A connecting rod is slidably connected to the inner wall of the fixed plate. A connecting member is fixedly connected to the front side of the shaft of the positioning wheel. A positioning plate is fixedly connected to the side of the connecting rod near the connecting member. A baffle is fixedly connected to the outside of the connecting rod. A spring is provided between the baffle and the fixed plate.

[0008] Preferably, the auxiliary component further includes an operating element, which is rotatably connected to the side of the connecting rod away from the positioning plate, and a limiting element is fixedly connected to the outside of the support.

[0009] Preferably, the limiting member has a groove on its outer side, and the operating member has a round rod on its front side, and the groove on the outer side of the limiting member and the round rod on the front side of the operating member can be engaged.

[0010] Preferably, the inner wall of the connector is provided with anti-slip texture.

[0011] Preferably, the moving part is T-shaped, and the driving part is a bidirectional threaded rod.

[0012] The technical effects and advantages provided by this utility model in the above technical solution are as follows: This utility model uses a support component that is slidably connected to the outside of the moving part, and is fixed by the insertion of positioning bolts and multiple sets of positioning holes. It is suitable for thin-walled parts of different specifications and meets the flexible production needs of multiple varieties and small batches on the production line. The positioning wheel is made of nylon and rolls against the outer wall of the thin-walled part when it comes into contact with it. Compared with the sliding friction of traditional rigid claws, this can avoid scratches on the outer wall of the thin-walled part.

[0013] This utility model achieves a quick locking or unlocking function by setting the interlocking cooperation between the operating component and the limiting component. During the welding process, the locking of the thin-walled component can be released, allowing the thin-walled component to be folded, thereby facilitating the welding operation.

[0017] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0018] This utility model provides, for example Figure 1 - Figure 3 An adjustable positioning auxiliary structure for welding thin-walled shock absorber components is shown, including a mounting frame 1 and a support assembly 7, specifically; The upper and lower parts of the mounting frame 1 are horizontally fixedly connected to multiple sets of guide rods 2. The mounting frame 1 is welded from 45# steel. The bottom of the mounting frame 1 has pre-set bolt holes, which can be directly fixedly connected to the workbench of the welding production line to ensure that the overall structure does not shake during the welding process of thin-walled parts and shock absorber piston rods / cylinders. The guide rods 2 provide linear sliding tracks for the moving parts 3 and the drive plate 4. Two sets of moving parts 3 are slidably connected to the outside of the guide rods 2. They slide horizontally along the guide rods 2, driving the support components 7 to adjust the radial spacing synchronously, which is suitable for thin-walled parts with a diameter of 30-80mm. By sliding the moving parts 3, the circumferential diameter of multiple sets of positioning wheels 74 can be quickly changed without replacing special components, improving changeover efficiency. The lower part of the moving parts 3 is fixedly connected to the drive plate 4. The lower part of the moving part 3 is supported, and the moving part 5 drives it to move in the opposite direction. The driving plate 4 is slidably connected to the outside of the guide rod 2. The bottom of the mounting frame 1 is rotatably connected to the driving part 5. The driving part 5 is set as a bidirectional threaded rod, which converts the rotational motion into linear motion. When rotating, it pushes the two sets of driving plates 4 to drive the two sets of moving parts 3 to slide in the opposite direction, so as to achieve precise adjustment of the radial spacing of the thin-walled part. It is more stable than manual pushing. At the same time, the inner wall of the driving plate 4 is provided with a threaded groove that cooperates with the driving part 5, which can increase the friction while ensuring the normal operation of the thread's self-locking ability. The driving part 5 is threadedly connected to the inner wall of the driving plate 4. The left side of the driving part 5 is fixedly connected to a handwheel 6, which can be easily rotated by the operator to complete the adjustment without the aid of tools. like Figure 1 and Figure 2 As shown, the support assembly 7 is located on the outside of the movable part 3 and is used for positioning and supporting the thin-walled part. The support assembly 7 includes multiple sets of support members 71. The support members 71 are slidably connected to the outside of the movable part 3 and slide vertically along the movable part 3. They can drive the positioning wheel 74 to adjust the height, with an adjustment range of 20-50mm, to adapt to thin-walled parts of different heights. The support members 71 are threadedly connected to the outside of the support members 71. The height of the support members 71 is locked by inserting the positioning hole 73. Loosening the bolt allows for sliding adjustment of the height. Tightening the bolt allows it to withstand an axial force of ≥50N, preventing the support members 71 from sliding down due to welding vibration. Two sets of support members 71 are also included. On the opposite side of the moving part 3, multiple sets of positioning holes 73 are horizontally opened. The hole diameter is adapted to the positioning bolt 72. The core function is to provide a multi-level height reference. The positioning holes 73 of different heights correspond to different thin-walled parts. The positioning bolt 72 is inserted into the inner wall of the positioning hole 73. On the opposite side of the multiple sets of support parts 71, positioning wheels 74 are rotatably connected. The positioning wheels 74 are made of nylon. Through multiple sets, a multi-point centering structure is formed to reduce the coaxiality error between the thin-walled part and the shock absorber cylinder. At the same time, it avoids the deformation of the thin-walled part due to rigid collision, reduces the shaping process after welding, and adapts to the flexible production needs of multiple varieties and small batches on the production line. like Figure 1 - Figure 3As shown, an auxiliary component 8 is provided on the outside of the support component 7. The auxiliary component 8 includes a fixed plate 81 fixedly connected to the front side of the support component 71, which is used to slide the connecting rod 82, providing installation space for the spring 85 and the baffle 84, ensuring that the components of the auxiliary component 8 are assembled in an orderly manner without looseness or shaking. The connecting rod 82 is slidably connected to the inner wall of the fixed plate 81, transmitting the preload of the spring 85, pushing the positioning plate 83 to press tightly against the connecting component 87, realizing the self-rotation locking of the positioning wheel 74. A connecting component is fixedly connected to the front side of the rotating shaft of the positioning wheel 74. 87. A positioning plate 83, made of nitrile rubber, is fixedly connected to the side of the connecting rod 82 near the connector 87. It is bonded to the end of the connecting rod 82 and prevents the positioning wheel 74 from rotating by frictional contact. A baffle 84 is fixedly connected to the outside of the connecting rod 82. Its function is to compress the spring 85 and transmit the elastic force. A spring 85 is provided between the baffle 84 and the fixing plate 81. It is sleeved on the outside of the connecting rod 82 and its two ends abut against the fixing plate 81 and the baffle 84 respectively, providing continuous pre-tightening force so that the positioning plate 83 is always in close contact with the connector 87.

[0019] like Figure 1 - Figure 3 As shown, the auxiliary component 8 also includes an operating member 86, which is rotatably connected to the side of the connecting rod 82 away from the positioning plate 83. It provides a manual unlocking interface. Pulling the operating member 86 pulls the connecting rod 82 to compress the spring 85, causing the positioning plate 83 to disengage from the connecting member 87 and releasing the lock on the positioning wheel 74. A limiting member 88 is fixedly connected to the outer side of the support member 71 to maintain the unlocked state. When the positioning plate 83 disengages from the connecting member 87, rotating the operating member 86 causes the round rod to engage with the groove, fixing the position of the connecting rod 82 without requiring continuous manual pulling. The limiting member 88 has a groove on its outer side, and the operating member 86 has a round rod on its front side. The groove on the outer side of the limiting member 88 and the round rod on the front side of the operating member 86 can engage. The inner wall of the connecting member 87 has anti-slip textures. The moving member 3 is T-shaped.

[0020] The working principle of this utility model is as follows: The operator turns the handwheel 6, which drives the drive component 5, which is rotatably connected to the bottom of the mounting frame 1, to rotate. The drive component 5 is threadedly connected to the inner wall of the drive plate 4, which can convert the rotational motion into linear motion, pushing the two sets of drive plates 4 to slide synchronously in the opposite direction along the guide rod 2. No special components need to be replaced, and the changeover efficiency is improved by 80%.

[0021] Based on the height of the thin-walled component, loosen the positioning bolts 72 on the outside of the support 71 and slide the support 71 vertically along the moving part 3. When the support 71 drives the positioning wheel 74 to align with the upper center of the thin-walled component, tighten the positioning bolts 72 to fix them in the positioning hole 73. After the moving part 3 drives the positioning wheel 74 to fix the thin-walled component, the positioning wheel 74 fits tightly against the outer wall of the thin-walled component, forming a multi-point centering structure. At this point, the thin-walled component can be welded to the shock absorber piston rod / cylinder to meet the flexible production needs of multiple varieties and small batches on the production line.

[0022] When it is necessary to fine-tune the angle of the thin-walled part, the operator pulls the operating part 86 on the side of the connecting rod 82 away from the positioning plate 83, which causes the connecting rod 82 to compress the spring 85, so that the positioning plate 83 is disengaged from the connecting part 87 and the locking of the positioning wheel 74 is released. At this time, the round rod-shaped structure of the operating part 86 is inserted into the groove of the outer limiting part 88 of the support part 71, which can fix the position of the connecting rod 82. There is no need for continuous manual pulling, freeing up both hands to adjust the angle of the thin-walled part and improving the convenience of operation.

[0023] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
