Description

Technical Field

[0001] This utility model relates to a welding device, and more specifically to a positioning mechanism, specifically a welding positioning device for a shock absorber dust cover. Background Technology

[0002] As a key component in mechanical equipment, the dust cover is an indispensable part of the shock absorber. Its main function is to protect the internal precision components such as the piston rod and oil seal of the shock absorber from the corrosion of dust, mud, water and other impurities, thereby extending the service life of the shock absorber and maintaining its optimal working condition.

[0003] During the manufacturing process of shock absorbers, dust covers are typically fixed to the shock absorber body or its accessories by welding. Traditional welding techniques, especially spot welding, are often used for this connection to ensure the dust cover's strength and airtightness.

[0004] However, the welding positioning of dust covers generally presents several challenges in existing technologies. For example, on many production lines, dust covers still require manual initial positioning and clamping before welding, or the use of relatively simple general-purpose fixtures. This method has low precision and is prone to inaccurate positioning due to factors such as operator fatigue and differences in skill level, which in turn affects welding quality and product consistency. Manual operation is inefficient and cannot meet the requirements of modern large-scale industrial production in terms of cycle time and capacity.

[0005] Furthermore, due to the varying sizes and shapes of dust covers for different models of shock absorbers, traditional fixtures often lack sufficient flexibility, making it difficult to quickly adapt to changes in product specifications. This results in lengthy production line adjustment times and increased production costs. Inaccurate positioning can also lead to defects such as weld misalignment, incomplete welds, and missing welds, affecting not only the sealing and protective effect of the dust cover but also potentially causing product rework or scrapping, further increasing production costs. The repetitive positioning and clamping work over extended periods also increases the labor intensity for workers and may pose certain safety hazards.

[0006] Therefore, developing a welding positioning device that can achieve high-precision, automated, and rapid positioning of shock absorber dust covers and adapt to various sizes is of great significance for improving the welding quality, production efficiency, and reducing production costs of shock absorber dust covers.

[0021] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0022] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0023] like Figure 1-5 As shown, a shock absorber dust cover welding and positioning device includes a workbench 1, a positioning mechanism 2 is provided in the middle of the workbench 1, and support legs 10 are welded to the four corners of the bottom of the workbench 1. The positioning mechanism 2 includes a support plate 201 embedded inside the workbench 1. Several cranks 203 are arranged circumferentially on the outer side of the support plate 201. Rollers 207 are movably installed at the upper end of the cranks 203. A first servo cylinder 209 is fixedly installed in the middle of the bottom of the support plate 201. The output end of the first servo cylinder 209 is connected to a lifting plate 211. The bottom end of the cranks 203 is circumferentially connected to the edge of the lifting plate 211 through a connecting rod 208.

[0024] In this embodiment, preferably, the workbench 1 has a mounting groove 8 in the middle, and an adjustment groove 9 is provided on the outer circumferential side of the mounting groove 8. The support plate 201 is fixedly installed inside the mounting groove 8. It should be noted that by setting the mounting groove 8 in the middle of the workbench 1 and fixing the support plate 201, and opening the adjustment groove 9 on its outer circumferential side, a solid and flexible base is provided for the entire positioning mechanism 2. The setting of the mounting groove 8 ensures the stable installation of the core support plate 201, effectively suppressing vibration and displacement during operation, thereby ensuring the high-precision positioning of the shock absorber dust cover before welding. The ingenious design of the circumferential adjustment groove 9 provides convenient space for subsequent connection and adjustment with linkage components such as the crank 203, enabling the positioning mechanism 2 to better adapt to the clamping requirements of dust covers of different sizes and models, greatly improving the product compatibility and rapid changeover capability of the device.

[0025] In this embodiment, preferably, the upper surface of the support plate 201 is provided with a placement groove 214, and a first connector 202 is provided on the outer circumferential side of the support plate 201. The first connector 202 is disposed inside the adjustment groove 9. It should be noted that the placement groove 214 on the upper surface of the support plate 201 provides initial, stable support and precise pre-positioning for the shock absorber dust cover; ensuring that the dust cover can reliably fall into place and be initially aligned before entering the final clamping state, effectively avoiding placement deviation; the first connector 202 circumferentially arranged on the outer side of the support plate 201 is cleverly embedded in the adjustment groove 9, which not only serves as a stable pivot point for the subsequent precise clamping action of the crank rod 203, ensuring the reliability and repeatability of the positioning mechanism 2, but also ensures the working space and protection of the crank rod 203, ensuring the smoothness and non-interference of the crank rod 203 when it adaptively adjusts to clamp dust covers of different sizes.

[0026] In this embodiment, preferably, a roller frame 206 is fixedly provided at the upper end of the crank 203, and a roller 207 is movably installed inside the roller frame 206. An inner protrusion 204 is fixedly provided on one side of the lower part of the crank 203, and the inner protrusion 204 is movably connected to the inside of the first connector 202 through a pin 213. It should be noted that the roller frame 206 fixedly mounted on the upper end of the crank 203 and the movably mounted roller 207 together form a highly efficient clamping end that directly contacts the dust cover of the shock absorber. The movable mounting design of the roller 207 allows for smooth contact with the outer wall of the dust cover, reducing friction and potential damage. It also provides a certain degree of flexibility during clamping to accommodate slight tolerances of the workpiece. Meanwhile, the inner protrusion 204 at the lower part of the crank 203 is movably connected to the first connector 202 via the pin 213, which is the core pivot point of the entire linkage clamping mechanism. This ensures that the crank 203 can swing or rotate stably and accurately around the core pivot point, efficiently converting the driving force of the first servo cylinder 209 into the circumferential adaptive clamping force of the roller 207 on the dust cover.

[0027] In this embodiment, preferably, the lower part of the support plate 201 is fixedly provided with an installation frame 210, the first servo electric cylinder 209 is fixedly installed inside the installation frame 210, the outer circumferential side of the lifting plate 211 is provided with a second connector 212, the bottom side of the crank rod 203 is fixedly provided with an outer protrusion block 205, the outer protrusion block 205 is movably connected to one end of the connecting rod 208 through a pin 213, and the other end of the connecting rod 208 is movably connected to the second connector 212 through a pin 213; It should be noted that the mounting frame 210 fixed at the lower part of the support plate 201 and the first servo electric cylinder 209 installed inside it provide the entire positioning mechanism 2 with a precise, programmable and responsive driving force. The use of the first servo electric cylinder 209 ensures the high precision and repeatability of the clamping action, and can accurately adjust the clamping force and stroke according to different workpiece requirements. The second connector 212 on the lifting plate 211 cleverly forms an efficient mechanical linkage transmission system through the connecting rod 208 and the protruding block 205 at the bottom of the crank rod 203. The linear reciprocating motion of the first servo electric cylinder 209 is accurately converted into the pulling adjustment of the crank rod 203, thereby driving the roller 207 to achieve circumferential clamping or loosening of the shock absorber dust cover. The pin shaft 213 is movably connected at each key node, ensuring smooth transmission without jamming, low friction and precise movement.

[0028] In this embodiment, preferably, an L-shaped frame 3 is fixedly provided at the middle tail of the workbench 1, a second servo electric cylinder 4 is fixedly installed on the L-shaped frame 3, the output end of the second servo electric cylinder 4 is connected to an installation head 5, a guide cylinder 6 is fixedly provided on one side of the installation head 5, and an electric welding head 7 is fixedly installed at the bottom of the installation head 5. It should be noted that the L-shaped frame 3 fixed at the rear of the middle of the worktable 1 provides a solid and stable base for the entire welding actuator, ensuring the mechanical stability of the welding process; the second servo electric cylinder 4 is the core drive unit, capable of high-precision, programmable displacement control; the precise output end of the second servo electric cylinder 4 is connected to the mounting head 5, which allows the movement path, speed, and stopping position of the welding head 7 to be precisely preset and repeatedly executed, ensuring positioning accuracy and weld consistency when welding the shock absorber dust cover; the mounting head 5 cleverly integrates the side-mounted guide cylinder 6 and the bottom welding head 7; the guide cylinder 6 ensures the precise introduction and stable supply of welding material, which is crucial for ensuring weld quality and welding process stability; while the bottom welding head 7 directly performs efficient and reliable welding operations.

[0029] The specific operational procedures for this application are as follows: The operator places the shock absorber dust cover in the placement groove 214 on the upper surface of the support plate 201 of the positioning mechanism 2. The placement groove 214 provides initial bearing and pre-positioning, ensuring that the dust cover is reliably placed and initially aligned, avoiding placement deviation. The control system issues a command to drive the first servo cylinder 209 installed inside the mounting frame 210 to start working. The output end of the first servo cylinder 209 drives the lifting plate 211 to perform linear reciprocating motion. The second connecting head 212 on the outer circumferential direction of the lifting plate 211 is movably connected to the connecting rod 208 through the pin 213. The other end of the connecting rod 208 is also movably connected to the outer protrusion 205 at the bottom of the crank rod 203 through the pin 213. With the movement of the lifting plate 211, this linkage system accurately converts the linear motion of the first servo cylinder 209 into the stable and precise adjustment of several circumferentially arranged crank rods 203. The inner protrusion 204 at the lower part of the crank 203 is movably connected to the inside of the first connecting head 202 on the outer circumferential direction of the support plate 201 via a pin 213, forming a core pivot point. When the crank 203 swings, the roller frame 206 fixed at its upper end and the movably mounted roller 207 will smoothly contact the outer wall of the dust cover and apply a circumferential adaptive clamping force to gently and accurately clamp and fix the dust cover in the preset welding position, while reducing friction and potential damage and accommodating the slight tolerance of the workpiece. The adjusting groove 9 provides an interference-free working space for the movement of the crank 203. The control system issues a command to drive the second servo cylinder 4, which is mounted on the L-shaped frame 3, to start working. The mounting head 5, connected to the output end of the second servo cylinder 4, drives the welding head 7 at its bottom and the guide cylinder 6 on the side to move precisely along the preset welding path. During the welding process, the guide cylinder 6 ensures the accurate introduction and stable supply of welding materials to guarantee the quality of the weld, or guides the cable through the weld. Under the high-precision control of the second servo cylinder 4, the welding head 7 performs efficient and reliable welding operations on the clamped and positioned shock absorber dust cover. After welding is completed, the control system drives the first servo electric cylinder 209 to move in the opposite direction; the lifting plate 211 moves in the opposite direction, and through the linkage of the connecting rod 208 and the crank rod 203, the roller 207 releases its grip on the dust cover; the operator removes the welded dust cover from the device.
