Technical Field

[0001] The invention relates to a non-standard welding fixture for automobile chassis parts, in particular to an integrated welding fixture for automobile shock absorbers. Background Art

[0002] like Figure 1 The figure shows the shock absorber, an automotive chassis component involved in the present invention, comprising a support 01, an outer panel 02 located in the middle of support 01, and an inner panel 03 located at the bottom of support 01. The support is a U-shaped structure consisting of two side panels and a center panel. The welding method for these three components is to first secure the support and inner panel using a first fixture, then weld the inner panel to the support. Next, remove the semi-finished weldment from fixture 1, secure the support and outer panel using a second fixture, and weld the outer panel to the support according to product requirements.

[0003] The aforementioned split-part welding method for shock absorbers requires repeated component positioning, increasing cumulative tolerances and resulting in low weld precision. This makes the process complex and challenging for operators. Furthermore, the outer panel tilt adjustment and the gap between the outer and inner panels are difficult to control during welding. Summary of the Invention

An inner plate mounting seat is arranged between the two control plates, and a pushing slider is movably provided on one side of the inner plate mounting seat. A clamping block acting on the inner plate is provided at the bottom of the pushing slider, and an adjustable support block assembly is provided on the surface of the pushing slider. The outer plate is installed on the pushing slider by adjusting the support block assembly. Adjusting the support block assembly will change the height and inclination angle of the outer plate.

[0006] A further preferred solution of the present invention is that the right side of the positioning plate is a reference surface, and the middle panel of the support is attached to the reference surface.

[0007] A further preferred solution of the present invention is that the side panel of the support is located inside the control panel, the output shaft of the stroke adjustment cylinder acts on the side panel of the support, and the operation of the stroke adjustment cylinder will control the opening size of the support.

[0008] A further preferred solution of the present invention is that a fixing assembly and a positioning pin for connecting the power assembly are provided on the left side of the positioning plate, and the positioning pin passes through the positioning plate and the support during operation.

[0009] A further preferred solution of the present invention is that a quick clamp is provided on the upper portion of the positioning plate, the quick clamp is connected to the pressure plate, and the quick clamp drives the pressure plate to be pressed and fixed to the middle panel of the support.

[0010] A further preferred solution of the present invention is that the pushing slider is located on the right side of the positioning plate, and the pressing block is in a T-shaped structure. The movement of the pushing slider drives the pressing block to move, and the moving pressing block presses the inner plate.

[0011] A further preferred solution of the present invention is that openings are provided on the front and rear sides of the base, and the control panel is suspended above the openings so as to be in contact with the side edges of the inner panel through the openings.

[0012] A further preferred solution of the present invention is that the pushing slider is installed on the slide rail and connected to the power component. A positioning pin connected to the power component is provided on the surface of the pushing slider. When the power component works, the positioning pin can be driven to move up and down and pass through the support.

[0013] A further preferred solution of the present invention is that a rotary cylinder is further provided on the base, and the rotary cylinder can act on the surface of the outer plate installed on the pushing slider.

[0015] Compared with the prior art, the advantage of the present invention is that the inner panel is first installed through the inner panel mounting seat, and then the support is positioned and installed through the positioning plate. The control panels on both sides of the positioning plate realize the regulation of the opening size of the U-shaped support. The outer panel is then installed on the pushing slider. The movement of the pushing slider will drive the outer panel to move to the predetermined position. In addition, a clamping block acting on the inner panel is provided at the bottom of the pushing slider. The movement of the pushing slider will also realize the compression of the inner panel. That is, after the pushing slider moves, both the inner panel and the outer panel will be transported to their positions and fixed. At this time, the inner panel, outer panel and support are all fixed in place, and the overall welding process can be carried out. An adjustable support block assembly is provided on the surface of the pushing slider. Adjusting the support block assembly will change the inclination angle of the outer panel and the height of the outer panel, that is, adjust the opening distance between the inner panel and the outer panel. The present invention solves the problem of product stability caused by multiple changes in the reference surface, and realizes the adjustability of the outer panel.

A pressure block 7 is located at the bottom of the push slider 6, acting on the inner plate 03. An adjustable support block assembly is mounted on the push slider 6. Adjusting the support block assembly changes the height and tilt angle of the outer plate 02. For welding the outer plate 02, a welding gun can be inserted directly from above. For welding the inner plate 03, the base 1 can be designed with slots for insertion or by modifying the base 1 (not a simple rectangular block) to expose the edges of the inner plate 03 for welding. Locating pins 16 are provided on the inner plate mounting base 5 to position the inner plate 03. The right side of the positioning plate 2 is the reference surface, and the middle panel of the support 01 is attached to the reference surface.

[0025] The side panel of the support 01 is located inside the control panel 3 , and the output shaft of the stroke adjustment cylinder 4 acts on the side panel of the support 01 . The operation of the stroke adjustment cylinder 4 will control the opening size of the support 01 .

[0026] The left side of the positioning plate 2 is provided with a fixing assembly 9 and a positioning pin 8 for connecting the power assembly. The positioning pin 8 will pass through the positioning plate 2 and the support 01. The positioning pin 8 will position the support 01 and ensure its position. The support 01 is then pressed and fixed by a fixing tool such as a quick clamp 10. The positioning pin 8 is provided for easy installation.

[0027] A quick-release clamp 10 is provided on the upper portion of the positioning plate 2. The quick-release clamp 10 is connected to a pressure plate 11. The quick-release clamp 10 is driven to press the pressure plate 11 against the middle panel of the support 01. The quick-release clamp 10 presses the support 01 to ensure that the support 01 can fit on the positioning plate 2.

[0028] Pushing slider 6 is located to the right of positioning plate 2, and holding block 7 is T-shaped. The movement of pushing slider 6 drives holding block 7 to move, which then compresses and secures inner panel 03. When inner panel 03 is installed, pushing slider 6 is away from support 01, leaving inner panel mounting base 5 exposed, facilitating installation of inner panel 03. Once inner panel 03 and support 01 are in place, outer panel 02 is mounted on pushing slider 6. The present invention operates, and pushing slider 6 moves, transporting outer panel 02 to the desired position while simultaneously securing inner panel 03.

[0029] The front and rear sides of the base 1 are provided with openings, and the control board 3 is suspended on the openings, through which the side of the inner plate 03 can be contacted. The structural setting of the present invention here is convenient for welding the inner plate 03.

[0030] The push slider 6 is mounted on the slide rail and connected to the power assembly. A positioning pin 15 connected to the power assembly is provided on the surface of the push slider 6. The power assembly operates to drive the positioning pin 15 up and down to pass through the support 01. In the present invention, the outer panel 02 is installed using an insert-and-clip method. Once the outer panel 02 is in place, only the positioning pin 15 needs to be activated to secure the outer panel 02.

[0031] A rotating cylinder 12 is also provided on the base 1, and the rotating cylinder 12 can act on the surface of the outer plate 02 mounted on the pushing slide 6. The present invention further presses the outer plate 02 by rotating the cylinder 12.

[0032] The support block assembly includes multiple shims 13 with adjustable thickness and two front and rear height-adjustable adjustment blocks 14. The shims 13 are arranged in two rows, with the outer panel 02 mounted on the shims 13, and the ends of the support 01 resting on the adjustment blocks 14. In this embodiment, the tilt of the support 01 can be varied by adjusting the height of the adjustment blocks 14. By varying the thickness of the shims 13 at different locations, the height and inclination of the outer panel 02 can be altered. This support block assembly arrangement meets the welding requirements of automotive shock absorbers.
