Technical Field

[0001] The invention relates to the technical field of automobile shock absorber welding, in particular to an automobile shock absorber welding tool provided with a pre-positioning mechanism. Background Art

[0002] During the production and processing of steel pipes and other accessories in automobile shock absorbers, corresponding welding steps need to be adapted. The welding tooling is the equipment for positioning automobile shock absorber pipes and other accessories. The quality of its texture determines the overall welding quality. For example, a tooling fixture for welding a steel pipe of an automobile shock absorber with a publication number of CN116000549B relates to the technical field of welding fixtures, and includes: a mounting portion; the control portion is arranged above the mounting portion; the clamping portion is arranged above the mounting portion; the welding portion is arranged in the middle of the mounting portion; the positioning portion is arranged at the top of the welding portion; a control rod is rotatably connected to the driving block, and is connected to the adjustment plate by a thread, so that the adjustment plate is controlled to move its position under the action of the thread, and its clamping structure is mostly in a fixed state, so that it is not convenient to adjust the shock absorber steel pipe after it is clamped, and it is usually necessary to perform repeated welding during the welding process, which leads to the problem that it needs to be repeatedly clamped to adjust the welding position; Another example is a welding tool for the lug of an oil storage cylinder of an automobile shock absorber with a publication number of CN113878257A. The welding tool for the lug of an oil storage cylinder of an automobile shock absorber comprises: a base, the upper surface of which is fixedly connected to a first hydraulic cylinder, the output end of which is fixedly connected to a connecting plate, the connecting plate being fixedly connected to a lug fixing cover having an open end and used to fix the lug; an oil storage cylinder fixing mechanism, the oil storage cylinder fixing mechanism being connected to the base; a welding gun guiding mechanism, the number of the welding gun guiding mechanisms being two, the two welding gun guiding mechanisms being respectively connected to two opposite surfaces of the lug fixing cover, and the movement directions of the active parts of the two welding gun guiding mechanisms being opposite; the active part of the welding gun guiding mechanism being located above the part to be welded between the lug and the oil storage cylinder bracket; For example, a welding tool for the oil storage cylinder lug of an automobile shock absorber with publication number CN105312817B includes a base and an oil storage cylinder support seat installed on the base, a bracket support plate and a baffle plate for blocking the end of the bracket. The base is also provided with a support column, and the support column is provided with a lug baffle plate for positioning the lug. The entire welding process time of the automobile shock absorber lug is shortened, production efficiency is improved, the position and dimensional accuracy after welding are guaranteed, the first-time qualified rate is improved, rework is reduced, and ordinary welders can also complete the welding operation, reducing the technical ability requirements of welders; Most of the above-mentioned existing technologies have improved their overall structure, and the existing automobile shock absorber welding tooling mostly requires manual assistance from the user during operation. It is impossible to perform pre-positioning operations while welding according to processing requirements, so as to adaptively self-position the contacting workpiece, and thus has certain usage limitations.

[0006] Furthermore, a nested docking piece is nested and docked inside the end of the built-in nested piece, and the nested docking piece and the soft supply pipe are arranged through, and a second reserved liquid bag is bonded and connected to the inner wall of the built-in nested piece, and the second reserved liquid bag and the end of the nested docking piece are connected to each other.

[0007] Furthermore, the movable docking reserved seat forms a sliding structure along the upper end of the preset base, and the movable docking reserved seat is rotationally connected to the built-in nesting part, and the built-in nesting part is docked with the soft supply pipe through the nested docking part.

[0008] Furthermore, the nested docking support member cooperates with the built-in resistance member to form a nested structure along the inner side of the movable docking reserved seat, and the built-in resistance member synchronously applies pressure to the contacted first reserved liquid capsule, and the first reserved liquid capsule forms a pressure supply structure with the inner side of the second reserved liquid capsule through the nested docking member and the soft supply pipe.

[0009] Furthermore, the secondary positioning structure is provided with a transverse accommodating reserved groove, and the transverse accommodating reserved groove is opened on the inner side of the built-in nested part, and a nested fitting docking part is nested and installed on the inner side of the transverse accommodating reserved groove, and a first spring is fixedly connected to the outer side of the nested fitting docking part, and the first spring and the inner side of the built-in nested part are docked with each other.

When welding processing is required, it is only necessary to nest the automobile shock absorber workpiece to be processed and place it horizontally inside the built-in nesting part.

The second spring drives the fitting positioning parts to move downward, and then the end of the workpiece in contact is subjected to secondary self-positioning treatment, so as to avoid looseness during processing and ensure its welding stability and processing quality. Furthermore, the built-in nested parts and the movable docking reserved seat for positioning the workpiece can be moved laterally stably and flexibly along the upper end of the preset base, and the built-in nested parts for positioning the workpiece can be rotated without dead angles along the inner side of the movable docking reserved seat as needed.
