Description

Technical Field

[0001] This utility model belongs to the field of vibration damper technology, and in particular relates to a universal welding fixture for dust covers. Background Technology

[0002] With the development of the vibration damper industry, the requirements for track vibration dampers are becoming increasingly stringent. To ensure the vibration damping effect of track vibration dampers, dust covers are usually welded onto them.

[0003] Currently, dust covers are typically welded to vibration dampers using a four-point welding process. However, dust covers welded using this process are prone to leaks and rust at the unwelded areas. To address this issue, the dust cover welding process has been optimized from four-point spot welding to a two-step process of four-point spot welding followed by seam welding, thus significantly mitigating these risks.

[0004] However, due to the limitations of equipment stroke and vibration damper length at present, each piece of equipment basically needs to be made with a unique tooling fixture according to each product model in order to weld the dust cover and vibration damper. This not only wastes a lot of resources, but also reduces welding efficiency. Utility Model Content

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0026] To effectively illustrate the embodiments of this utility model, the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0027] See Figures 1 to 3 As shown, this application discloses a universal seam welding fixture for dust covers, used to fix vibration dampers and dust covers mounted on a machine frame, thereby facilitating seam welding of the vibration dampers and dust covers. Specific details can be found in the following embodiments.

[0028] like Figure 1 As shown, the universal seam welding fixture for dust covers disclosed in this application includes an adjustable pressure head assembly and an adjustable base assembly. The adjustable pressure head assembly and the adjustable base assembly are used together. Typically, the adjustable base assembly is fixed to a frame, which mainly refers to a frame or welding platform used to fix the vibration damper and the dust cover, thereby allowing the adjustable base assembly to fix the vibration damper cylinder. The adjustable pressure head assembly can be fixed to a mechanical claw on the top of the frame or a telescopic rod that can move up and down, thereby allowing the adjustable pressure head assembly to fix the dust cover. In specific implementation, the adjustable pressure head assembly and the adjustable base assembly are vertically aligned. Thus, when the adjustable pressure head assembly fixes the dust cover and the adjustable base assembly fixes the vibration damper, the dust cover and the vibration damper can be fundamentally connected when the adjustable pressure head assembly moves downward, thereby ensuring the stability of the dust cover and the vibration damper during the seam welding process. Furthermore, the adjustable pressure head assembly and the adjustable base assembly are screw telescopic structures, which can realize the length extension and retraction functions of the adjustable pressure head assembly and the adjustable base assembly, thereby adapting to equipment with different strokes and vibration dampers of different lengths, facilitating the efficiency and versatility of seam welding.

[0029] In the specific implementation process, it can be combined with Figure 2As shown, the adjustable pressure head assembly includes a pressure head 3, an adjustable pressure column 2, and a first locking nut 1. The first locking nut 1 is located at the top of the adjustable pressure column 2, and the pressure head 3 is located at the bottom of the adjustable pressure column 2. The adjustable pressure column 2 is a lead screw telescopic pressure column. The first locking nut 1 is used for adjusting and locking the adjustable pressure column 2, and the pressure head 3 is used to fix the dust cover. Figure 3 As shown, the pressure head 3 consists of two opposing limiting plates 31 and a V-shaped block 32. The V-shaped block 32 is disposed between the two limiting plates 31, and the arc-shaped outer wall of the limiting plates 31 faces outward, so that the two limiting plates 31 can be inserted into the dust cover to fix the dust cover.

[0030] Of course, in the specific implementation process, the size of the pressure head 3, i.e., the two limiting plates 31, is equal to the inner diameter of the smallest dust cover. This smallest dust cover inner diameter is usually the size of the smallest dust cover used for welding the vibration damper. This also ensures that the pressure head 3 can fix other dust covers and avoids interference with the weld seam pads, ensuring versatility. In the specific implementation process, the two limiting plates 31 can also move in opposite directions along the V-block 32, and the limiting plates 31 can be locked and fixed on the base plate, thereby fixing dust covers of different sizes. The specific details will not be elaborated again, but can be referred to the relevant existing technology.

[0031] In addition, in the specific implementation process, combined with Figure 3 As shown, the adjustable base assembly includes a base 4, an adjustable bracket 5, and a second locking nut 6. The top of the adjustable bracket 5 is fixed to the base 4, and the bottom of the adjustable bracket 5 is fixed to the second locking nut 6. The adjustable bracket 5 is a lead screw telescopic bracket, and the second locking nut 6 is used for adjusting and locking the adjustable bracket 5. The base 4 is used to fix the shock absorber. Furthermore, the base 4 is a V-shaped universal base, which can achieve the fixing of different models of shock absorbers.

[0032] The universal seam welding fixture for dust covers provided in this application embodiment has a pressure head 3 that is compatible with the size of the vibration damper, ensuring versatility without affecting functionality (no interference with the seam welding pad). The length can be adjusted via a lead screw, achieving seam welding effects for different stroke equipment and vibration dampers of different lengths.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
