Description

Technical Field

[0001] This utility model relates to the field of welding technology for U-shaped fork connecting rods of shock absorbers, and in particular to a single-gun welding machine tooling for U-shaped fork connecting rods of shock absorbers. Background Technology

[0002] In the production of vibration dampers, the U-shaped fork connecting rod is a key component, and its welding quality has a crucial impact on the overall performance and reliability of the damper. Traditional welding processes often employ manual operation or relatively simple tooling equipment, which presents numerous problems. For example, during manual welding, due to factors such as the operator's skill level and fatigue, it is difficult to ensure the consistency and stability of the weld, easily leading to welding defects such as incomplete welds, missed welds, and uneven welds, thereby affecting product quality and production efficiency. Furthermore, for some U-shaped fork connecting rods with complex shapes and high precision requirements, manual welding is insufficient to meet their high-precision assembly and welding requirements.

[0003] With the automotive industry and other sectors continuously raising their requirements for shock absorber performance and expanding their production scale, the market urgently needs an advanced tooling equipment that can improve the welding quality and production efficiency of U-shaped fork connecting rods to meet the demands of large-scale, high-precision production.

[0004] Existing tooling for welding the U-shaped fork and connecting rod of a shock absorber requires multiple welding torches to simultaneously weld the joint between the U-shaped fork and the connecting rod after clamping them separately, increasing costs. Therefore, we propose a single-torch welding tooling for the U-shaped fork and connecting rod of a shock absorber to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to solve the problem that existing tooling requires multiple welding guns to simultaneously weld the joint of the U-shaped fork and connecting rod of a shock absorber when welding them, which increases costs. Therefore, this invention proposes a single-gun welding tooling for the U-shaped fork and connecting rod of a shock absorber.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A single-gun welding fixture for a vibration damper U-shaped fork connecting rod includes: The rotating mechanism includes a rotating seat rotatably mounted on a welding machine base and a carrier fixed on the rotating seat. A rotary motor for driving the rotating seat and the carrier to rotate and adjust is fixed at the bottom of the welding machine base. The welding mechanism includes a welding torch for welding the U-shaped fork of the shock absorber, which is positioned diagonally above the welding position on the vehicle, and a welding torch stand on the welding machine for welding support. The docking mechanism includes a connecting rod positioning sleeve that is vertically and vertically disposed above the welding position of the shock absorber U-shaped fork for docking with the shock absorber connecting rod, and a clamping component that is movably disposed above the welding position of the shock absorber U-shaped fork for multi-directional clamping of the shock absorber U-shaped fork.

[0007] Furthermore, the welding machine platform is equipped with a lifting plate rotatably connected to the connecting rod positioning sleeve, a lifting cylinder fixedly connected to the lifting plate for driving the connecting rod positioning sleeve to move, and a bracket mounted on the welding machine platform for stable support of the lifting cylinder.

[0008] Furthermore, a limiting rod is slidably mounted on the bracket and connected to the lifting plate to limit the movement trajectory of the connecting rod positioning sleeve.

[0009] Furthermore, the clamping assembly includes a fixed column movably mounted on the welding machine platform and a fixing cylinder symmetrically mounted on the welding machine platform and connected to the two fixed columns respectively for driving the fixed columns to fix the U-shaped fork to be welded. A side pressure plate for clamping the side of the U-shaped fork of the shock absorber is movably mounted on the carrier around the welding position of the U-shaped fork of the shock absorber. The clamping cylinder is fixed on the carrier and connected to the side pressure plate.

[0010] Furthermore, the carrier is equipped with a placement seat for placing the U-shaped fork of the shock absorber at the welding position of the shock absorber, and a limiting plate for limiting the U-shaped fork of the shock absorber is fixed on the side of the placement seat away from the side pressure plate.

[0011] Furthermore, the inner opening of the shock absorber U-shaped fork corresponds to the two pads installed on the placement seat, and the pads are provided with positioning holes for the two fixing posts to be inserted and fixed.

[0012] Compared with the prior art, the advantages of this utility model are: 1. In this solution, two fixed cylinders drive the fixed columns to clamp the U-shaped fork, and the pressure cylinder drives the side pressure plate to fix the side of the U-shaped fork, thus achieving multi-directional stable fixation of the U-shaped fork; 2. This solution uses a lifting cylinder to drive the lifting plate to move downwards. Combined with the sliding between the two limit rods and the top plate, it causes the connecting rod positioning sleeve to move vertically downwards, thereby achieving precise vertical docking between the connecting rod and the U-shaped fork. 3. This solution starts a rotary motor, which drives the rotating seat and carrier to rotate. Due to the rotation setting of the connecting rod positioning sleeve, the clamping assembly and the upper connecting rod can rotate synchronously. With the help of a single welding gun, it can achieve full welding of the joint between the shock absorber U-shaped fork and the connecting rod, thus improving welding efficiency and quality.

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Reference Figures 1-5 A single-gun welding fixture for a U-shaped fork connecting rod of a vibration damper, comprising: The rotating mechanism includes a rotating seat 2 rotatably mounted on the welding machine base 1 and a carrier 3 fixed on the rotating seat 2. A rotary motor 201 for driving the rotating seat 2 and the carrier 3 to rotate and adjust is fixed at the bottom of the welding machine base 1. The welding mechanism includes a welding torch 706 for welding the shock absorber U-shaped fork 8, which is positioned diagonally above the welding position on the carrier 3, and a welding torch 706 set 705 for welding support on the welding machine base 1. The docking mechanism includes a connecting rod 9 positioning sleeve 703 that is vertically and vertically mounted above the welding position of the shock absorber U-shaped fork 8 for docking the shock absorber U-shaped fork 8 with the shock absorber connecting rod 9, and a clamping component that is movably mounted above the welding position of the shock absorber U-shaped fork 8 for multi-directional clamping of the shock absorber U-shaped fork 8.

[0018] In this embodiment, the rotating mechanism works in conjunction with the welding gun 706 to achieve full welding at the joint between the U-shaped fork 8 and the connecting rod 9 of the shock absorber, thereby improving welding efficiency and quality. The positioning sleeve 703 of the connecting rod 9 can fix the connecting rod 9 of the shock absorber.

[0019] Reference Figure 1 The welding machine base 1 is equipped with a lifting plate 702 that is rotatably connected to the positioning sleeve 703 of the connecting rod 9, a lifting cylinder 701 that is fixedly connected to the lifting plate 702 to drive the positioning sleeve 703 of the connecting rod 9 to move, and a bracket 7 that is mounted on the welding machine base 1 to provide stable support for the lifting cylinder 701. A limiting rod 704 that is connected to the lifting plate 702 and used to limit the movement trajectory of the positioning sleeve 703 of the connecting rod 9 is slidably installed on the bracket 7.

[0020] In this embodiment, when the lifting cylinder 701 drives the lifting movement up and down, the sliding between the limit rod 704 and the bracket 7 provides a limit for the movement trajectory of the lifting plate 702, thereby improving the stability of the lifting.

[0021] Reference Figure 1 , Figure 2 and Figure 3 The clamping assembly includes a fixed column 401 movably mounted on the welding machine 1 and a fixing cylinder 4 symmetrically mounted on the welding machine 1 and connected to the two fixed columns 401 respectively for driving the fixed columns 401 to fix the U-shaped fork 8 to be welded. A side pressure plate 501 for clamping the side of the U-shaped fork 8 is movably mounted on the carrier 3 around the welding position of the U-shaped fork 8. A clamping cylinder 5 is fixed on the carrier 3 and connected to the side pressure plate 501. A placement seat 6 for placing the U-shaped fork 8 is installed on the carrier 3 corresponding to the welding position of the U-shaped fork 8. A limiting plate 601 for limiting the movement of the U-shaped fork 8 is installed on the side of the placement seat 6 away from the side pressure plate. Two pads are installed on the inner opening of the U-shaped fork 8 corresponding to the placement seat 6. The pads have positioning holes for the two fixed columns 401 to be inserted and fixed.

[0022] In this embodiment, the U-shaped fork 8 can be fixed when the two fixing posts 401 are close to each other, and the side pressure plate 501 can press and fix the side of the U-shaped fork 8 under the drive of the clamping cylinder 5. At the same time, the setting of the limiting plate 601 provides a certain limit when the side pressure plate 501 fixes the U-shaped fork 8, which further improves the stability of clamping. The two gaskets can be placed according to the size of the opening inside the U-shaped fork 8, so that the U-shaped fork 8 will not be damaged by excessive clamping when clamped by the two fixing posts 401.

[0023] The implementation principle of the single-gun welding machine tooling for a U-shaped fork 8 and connecting rod 9 of a vibration damper according to an embodiment of this application is as follows: The U-shaped fork 8 is placed on the placement seat 6. Two fixed cylinders 4 drive two fixed columns 401 to move closer together to clamp the U-shaped fork 8, thereby fixing the fork hole of the U-shaped fork 8. Then, a clamping cylinder drives a pressure plate to move closer to the side of the U-shaped fork 8, achieving the effect of fixing the side of the U-shaped fork 8. Next, the connecting rod 9 is inserted into the positioning sleeve 703 of the connecting rod 9. A lifting cylinder 701 drives a lifting plate 702 to move downwards. Simultaneously, the sliding between the two limit rods 704 and the top plate causes the positioning sleeve 703 of the connecting rod 9 to move vertically downwards, thereby driving the connecting rod 9 to precisely align with the U-shaped fork 8, thus achieving multi-directional fixing of the U-shaped fork and... The connecting rod 9 is precisely aligned with the U-shaped fork 8, ensuring greater stability when welding the joint between the U-shaped fork 8 and the connecting rod 9. When welding the joint between the shock absorber U-shaped fork 8 and the connecting rod 9 is required, welding is performed using the welding torch 706. Then, the rotary motor 201 is started, driving the rotating seat 2 to rotate. The carrier 3 follows the rotation trajectory of the rotating seat 2. Since the positioning sleeve 703 of the connecting rod 9 is rotatably mounted on the lifting plate 702, the rotation of the carrier 3 drives the clamping assembly and the upper connecting rod 9 to rotate synchronously. At the same time, it works in conjunction with the welding torch 706 to perform welding work on the joint to be welded. This allows for comprehensive welding of the joint between the shock absorber U-shaped fork 8 and the connecting rod 9 using a single welding torch 706 after the shock absorber U-shaped fork 8 and the connecting rod 9 have been clamped and aligned separately.

[0024] All structures in this application can be customized in terms of material and length according to actual usage. The attached drawings are schematic structural diagrams, and the actual dimensions can be adjusted accordingly.

[0025] The above description is only a preferred embodiment of this practice, but the scope of protection of this embodiment is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the scope of the technology disclosed in this embodiment, based on the technical solution and the inventive concept of this embodiment, should be covered within the scope of protection of this embodiment.
