Technical Field

[0001] The present invention belongs to the technical field of shock absorbers, and particularly relates to a universal seam welding tooling for dust covers. Background Art

[0002] With the development of the shock absorber industry, the requirements for track shock absorbers are getting higher and higher. In order to ensure the shock absorption effect of the track shock absorber, it is usually necessary to weld a dust cover on the track shock absorber.

[0003] At present, for the welding of the dust cover, it is usually welded on the shock absorber through a four-point welding process. However, there is a situation where the un-welded part of the dust cover welded by the four-point welding process leaks water and rusts. To solve this problem, the dust cover welding process is optimized from four-point spot welding to two steps of four-point spot welding + seam welding, thereby greatly avoiding such risks for the dust cover.

[0004] However, at the present stage, due to the problems of the equipment stroke and the length of the shock absorber, basically, a unique tooling fixture needs to be made for each equipment according to each product model to realize the welding of the dust cover and the shock absorber. On the one hand, it greatly wastes resources, and on the other hand, it also reduces the welding efficiency. Summary of the Invention

[0019] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention 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 only used to explain the present invention and are not used to limit the present invention.

[0020] In order to effectively illustrate the embodiments of the present invention, the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0021] See Figures 1 to 3 As shown, this application discloses a universal seam welding tooling for a dust cover, which is used to fix a shock absorber and a dust cover arranged on a frame, so as to facilitate seam welding of the shock absorber and the dust cover. Specifically, it can be described with reference to the following implementation manners.

[0022] As Figure 1 shown, the universal seam welding tooling for a dust cover 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 in cooperation. Generally, the adjustable base assembly is fixed to a frame, and the frame mainly refers to a frame body or a welding platform for fixing a shock absorber and a dust cover, so that the adjustable base assembly fixes the shock absorber cylinder body. The adjustable pressure head assembly can be fixed to a mechanical claw at the top of the frame or a telescopic rod that can move up and down, so that the adjustable pressure head assembly fixes the dust cover. In the specific implementation process, the adjustable pressure head assembly and the adjustable base assembly are corresponding up and down. Thus, when the adjustable pressure head assembly fixes the dust cover and the adjustable base assembly fixes the shock absorber, when the adjustable pressure head assembly moves downward, the basic docking of the dust cover and the shock absorber can be realized, so that the stability of the dust cover and the shock absorber can be ensured during the seam welding process. Moreover, the adjustable pressure head assembly and the adjustable base assembly are of a lead screw telescopic structure, which can realize the length telescopic function of the adjustable pressure head assembly and the adjustable base assembly, so as to adapt to different stroke devices and different length shock absorbers, and facilitate the efficiency and versatility of seam welding.

[0023] In the specific implementation process, it can be combined with Figure 2As shown in the figure, the adjustable pressure head assembly includes a pressure head 3, an adjustable pressure column 2, and a first locking nut 1. Among them, the first locking nut 1 is arranged at the top end of the adjustable pressure column 2, and the pressure head 3 is arranged at the bottom end of the adjustable pressure column 2; the adjustable pressure column 2 is a 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 for fixing the dust cover. As Figure 3 shown, the pressure head 3 is composed of two oppositely arranged limiting plates 31 and a V-shaped block 32. The V-shaped block 32 is arranged between the two limiting plates 31, and the arc-shaped outer walls of the limiting plates 31 face outward, so that the two limiting plates 31 can be inserted into the dust cover to fix the dust cover.

[0024] Of course, in the specific implementation process, the size of the pressure head 3, that is, the two limiting plates 31, is equal to the minimum inner diameter of the dust cover. The minimum inner diameter of the dust cover is usually the inner diameter of the smallest dust cover used for the welding of the shock absorber. In this way, it can also ensure that the pressure head 3 can fix other dust covers, and can also ensure avoiding interference with the seam welding pad and ensure universality. In the specific implementation process, the two limiting plates 31 can also move in opposite or opposite directions along the V-shaped block 32, and the limiting plates 31 can be locked and fixed on the bottom plate, so as to fix dust covers of different sizes. The specific situation will not be elaborated in detail again, and relevant prior art can be referred to.

[0025] In addition, in the specific implementation process, in combination with Figure 3 shown, the adjustable base assembly includes a base 4, an adjustable bracket 5, and a second locking nut 6. The base 4 is fixed at the top of the adjustable bracket 5, and the second locking nut 6 is fixed at the bottom of the adjustable bracket 5; the adjustable bracket 5 is a screw telescopic bracket, the second locking nut 6 is used for adjusting and locking the adjustable bracket 5, and the base 4 is used for fixing the shock absorber. And the base 4 is a V-shaped universal base, which can realize the fixation of shock absorbers of different models.

[0026] Through the dust cover universal seam welding tooling provided by the embodiment of the present application, the pressure head 3 is adapted to the size of the shock absorber, and universality is ensured on the premise of not affecting the function (not interfering with the seam welding pad). The length can be adjusted by the screw, and for different stroke devices and shock absorbers of different lengths, the seam welding effect can be achieved.

[0027] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
