Description
Technical field:
[0001] The utility model relates to a full-load-bearing frame independent suspension positioning welding tool, which belongs to the technical field of welding positioning tooling. Background technology:
[0002] The front independent suspension of the vehicle frame is not a whole part, but is composed of five independent parts. Traditional positioning tooling is to use specific tooling for positioning welding after the frame welding is completed. There are problems such as poor positioning consistency and positioning errors caused by human factors.
[0003] Therefore, it is necessary to improve the existing technology to solve the shortcomings of the existing technology. Utility model content:
[0004] The utility model is to solve the problems existing in the above-mentioned prior art and provide a full-load-bearing frame independent suspension positioning welding tool, which integrates the independent suspension positioning tool and the frame welding tool, and adds an error-proofing function to avoid the problems of secondary positioning and erroneous operation caused by human factors.
[0005] The utility model adopts the following technical scheme: a full-load-bearing frame independent suspension positioning welding tool, including a base plate and a mounting groove formed on the base plate, an upper cross arm support positioning plate, a rocker arm support assembly positioning plate and a lower A-type arm support assembly positioning plate are welded and fixed in the mounting groove, the upper cross arm support positioning plate includes two spaced apart and oppositely arranged, a first pad is installed on the opposite surfaces of the two upper cross arm support positioning plates respectively through positioning pins, the rocker arm support assembly positioning plate includes two spaced apart and oppositely arranged, a second pad is installed on the opposite surfaces of the two rocker arm support assembly positioning plates respectively through positioning pins, the lower A-type arm support assembly positioning plate includes two spaced apart and third pads are installed on the opposite surfaces of the two lower A-type arm support assembly positioning plates respectively through positioning pins.
[0006] Furthermore, the rocker arm support assembly positioning plate and the lower A-arm support assembly positioning plate are located between the two upper cross arm support positioning plates.
[0007] Furthermore, a first reinforcing rib is fixed on the surface of the upper cross arm support positioning plate on which the first pad is not installed.
[0008] Furthermore, a second reinforcing rib is fixed on the surface of the rocker arm support assembly positioning plate on which the second pad is not installed.
[0009] Furthermore, a third reinforcing rib is fixed on the surface of the lower A-arm support assembly positioning plate on which the third pad is not installed.
[0010] The utility model has the following beneficial effects:
[0011] 1. The positioning and welding tooling for the independent suspension of the full - load - bearing vehicle frame of the present utility model can accurately position, ensuring the relative position accuracy between the rocker arm support assembly, the upper cross - arm support, and the lower A - type arm support assembly;
[0012] 2. The 8 - mm backing plates between the positioning plates of the rocker arm support assembly, the upper cross - arm support positioning plate, the lower A - type arm support assembly positioning plate and the skeleton can ensure smooth demolding. Description of the Drawings:
[0013] Figure 1 It is a schematic diagram of the positioning and welding tooling for the independent suspension of the full - load - bearing vehicle frame of the present utility model. Specific Embodiments:
[0014] The following further describes the present utility model with reference to the drawings.
[0015] The positioning and welding tooling for the independent suspension of the full - load - bearing vehicle frame of the present utility model includes a bottom plate 1 and an installation groove formed on the bottom plate 1. In the installation groove, an upper cross - arm support positioning plate 2, a rocker arm support assembly positioning plate 3, and a lower A - type arm support assembly positioning plate 4 are welded and fixed. The upper cross - arm support positioning plate 2 includes two spaced - apart and relatively - arranged ones. On the opposite surfaces of the two upper cross - arm support positioning plates 2, first backing plates 5 are respectively installed through positioning pins. The rocker arm support assembly positioning plate 3 includes two spaced - apart and relatively - arranged ones. On the opposite surfaces of the two rocker arm support assembly positioning plates 3, second backing plates 6 are respectively installed through positioning pins. The lower A - type arm support assembly positioning plate 4 includes two spaced - apart ones. On the opposite surfaces of the two lower A - type arm support assembly positioning plates 4, third backing plates 7 are respectively installed through positioning pins.
[0016] Among them, the rocker arm support assembly positioning plate 3 and the lower A - type arm support assembly positioning plate 4 are located between the two upper cross - arm support positioning plates 2.
[0017] On the surface of the upper cross - arm support positioning plate 2 where the first backing plate 5 is not installed, a first reinforcing rib 8 is fixed. On the surface of the rocker arm support assembly positioning plate 3 where the second backing plate 6 is not installed, a second reinforcing rib 9 is fixed. On the surface of the lower A - type arm support assembly positioning plate 4 where the third backing plate 7 is not installed, a third reinforcing rib 10 is fixed.
[0018] The working principle of the positioning welding tooling of the full-load-bearing frame independent suspension of the present invention is as follows: the various components of the independent suspension are positioned and fixed by positioning threaded pins and the upper cross arm support positioning plate 2, the rocker arm support assembly positioning plate 3 and the lower A-type arm support assembly positioning plate 4. At the same time, in order to ensure smooth demolding without squeezing the upper cross arm support positioning plate 2, the rocker arm support assembly positioning plate 3 and the lower A-type arm support assembly positioning plate 4, a first pad 5, a second pad 6 and a third pad 7 of 8mm are added between the upper cross arm support positioning plate 2, the rocker arm support assembly positioning plate 3 and the lower A-type arm support assembly positioning plate 4 and the various components of the independent suspension. When the welding is completed and the demolding is completed, the first pad 5, the second pad 6 and the third pad 7 are first taken out, and then the entire welded component is removed as a whole.
[0019] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements can be made without departing from the principles of the present invention. These improvements should also be regarded as the scope of protection of the present invention.
