[0040] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0041] See Figures 1 to 4 As shown;

[0042] This embodiment provides a vehicle body footrest pocket assembly and a welding deformation control device, the device comprising:

[0043] Tooling support base 1;

[0044] The dimension positioning assembly is fixed to the tooling support base 1. The dimension positioning assembly consists of two symmetrically arranged dimension positioning uprights 2; and

[0045] Multiple clamping mechanisms are arranged on the tooling support base 1. The clamping mechanisms are used to clamp the corresponding positions of the foot pedal pocket 10 in the corresponding process.

[0046] Two size positioning plates 2 are used to abut against the corresponding positions of the foot pedal pocket 10, and an anti-deformation pad is fixed at the position where the tooling support base 1 contacts the foot pedal pocket 10.

[0047] Specifically, this embodiment discloses a device suitable for assembling and welding 10 pedal pockets on a vehicle body, and featuring anti-deformation control. It includes a tooling support base 1 serving as the tooling foundation, and multiple clamping mechanisms. Furthermore, to control the dimensions of the 10 pedal pockets during assembly and welding, a dimensional positioning plate 2 and a dimensional positioning block 3 are designed. Depending on the requirements of different weld seams in different welding processes of the pedal pockets 10, the placement of the pedal pockets 10 can be adjusted, and the corresponding clamping mechanisms can be used to position and fix the bracket 11 and support plate 12, preventing workpiece movement. Simultaneously, the close contact between the dimensional positioning plate 2 and the dimensional positioning block 3 maintains their relative positions, thereby controlling the welding dimensions. Finally, anti-deformation control is achieved through an anti-deformation pad at the bottom of the workpiece.

[0048] Preferably, in this embodiment, both the size positioning plate 2 and the tooling support base 1 are provided with size positioning blocks 3 that abut against the edge of the foot pedal pocket 10.

[0049] Based on the process requirements for welding 10 pairs of foot pedal pockets, first refer to... Figure 1 As shown, Figure 1The structure of the pedal pocket 10 to be processed is shown, which includes a bracket, bracket extensions on both sides of the bracket 11, and a middle area of ​​the bracket 11 that is assembled and welded to the support plate 12. Therefore, based on the structure of the pedal pocket 10, the pedal pocket 10 in this embodiment is divided into two processes: vertical fixing and horizontal fixing.

[0050] See Figure 3 As shown, when the foot pedal pocket 10 is vertically fixed, the two sides of the foot pedal pocket 10 are attached to the two side size positioning plates 2, and the corresponding edge of the foot pedal pocket 10 is respectively abutted and positioned by the size positioning block 3, and pressed by the pressing mechanism located in the middle of the tooling support base 1.

[0051] See Figure 4 As shown, when the foot pedal pocket 10 is fixed horizontally, the two sides of the foot pedal pocket 10 are attached to the two side size positioning plates 2, and the position of the foot pedal pocket 10 bracket 11 and the support plate 12 is pressed by the pressing mechanism located in the middle of the tooling support base 1, while the part of the foot pedal pocket 10 bracket 11 extending to the outside of the size positioning plate 2 is pressed by two symmetrically arranged pressing mechanisms.

[0052] Based on the two arrangement forms mentioned above, and the requirements for positioning, clamping, and fixing, this embodiment divides the clamping mechanism into two categories, namely:

[0053] The clamping mechanism located in the middle of the tooling support base 1 is the first clamping mechanism 401, and the two clamping mechanisms located on the rear side of the tooling support base 1 and arranged symmetrically are the second clamping mechanism 402.

[0054] Two first anti-deformation pads 501 are provided between the two size positioning uprights 2, and the first anti-deformation pads 501 are fixed to the surface of the tooling support base 1.

[0055] A second anti-deformation pad 502 is provided between the size positioning plate 2 and the corresponding second pressing mechanism 402, and the second anti-deformation pad 502 is fixed to the surface of the tooling support base 1.

[0056] Based on the arrangement of the above-mentioned pressing mechanism and the arrangement of the two processes of the foot pedal pocket 10, further, when the foot pedal pocket 10 is vertically fixed in this embodiment, the bottom of the connection part between the bracket 11 and the support plate 12 of the foot pedal pocket 10 is supported on the surface of the first anti-deformation pad 501.

[0057] When the foot pedal pocket 10 is fixed horizontally, the side of the connection between the bracket 11 and the support plate 12 of the foot pedal pocket 10 is supported on the surface of the first anti-deformation pad 501, and the side of the extension of the bracket 11 of the foot pedal pocket 10 is supported on the surface of the second anti-deformation pad 502.

[0058] In this embodiment, the dimensional positioning block located on the tooling support base 1 is arranged between two first anti-deformation pads 501.

[0059] In this embodiment, the pressing end of the first pressing mechanism 401 is located between two first anti-deformation pads 501; the pressing end of the second pressing mechanism 402 is located directly above the corresponding second anti-deformation pad 502.

[0060] The clamping mechanism involved in this embodiment is a conventional tooling fixture, so its structure is not specifically limited. It is only limited to the two different arrangement methods of the clamping mechanism to adapt to the 10 pairs of foot pedal pockets and the welding process.

[0061] Based on the above-mentioned arrangement of the various mechanisms, the processing steps based on this device in the footrest pocket 10 process of this embodiment mainly include:

[0062] S1. First, place the bracket 11 between two size positioning plates 2, and support the middle position of the bracket 11 on the first anti-deformation pad 501. At the same time, the side of the bracket 11 at the corresponding position is in close contact with the corresponding size positioning block 3.

[0063] S2. Place the support plate 12 in the middle of the bracket 11 and position it. Then, press the support plate 12 and the bracket 11 together with the first pressing mechanism 401 and fix them in place.

[0064] S3. Rotate the workpiece after step S2 by 90° and support it on the corresponding anti-deformation pad. At the same time, use the first pressing mechanism 401 and the second pressing mechanism 402 to press the corresponding position of the workpiece and perform welding on that side.

[0065] S4. After the workpiece welded in step S3 has cooled down, loosen the clamping mechanism, rotate it 180°, and then clamp it again using the clamping mechanism before welding the weld seam on that side.

[0066] In the above technical solution, the vehicle body footrest pocket assembly and welding deformation control device provided by this utility model have the following beneficial effects:

[0067] The device of this invention is used to solve the problems of low dimensional accuracy and welding deformation control in the manufacturing process of the footrest pocket 10 of the vehicle body. The manufacturing process of the footrest pocket assembly by this device can be simplified, ultimately ensuring product quality, reducing labor, and improving production efficiency.

[0068] This invention addresses the issues of assembling and welding deformation control of the 10-piece pedal pocket assembly. By using a dimensional positioning block 3 and a dimensional positioning upright plate 2 to position the pedal pocket assembly, it solves the problems of dimensional alignment accuracy and slow assembly process. Furthermore, by using an anti-deformation pad at the bottom of the workpiece and a pressing mechanism above, it solves the welding deformation problem of the 10-piece pedal pocket assembly and eliminates the need for post-weld mechanical adjustment and manufacturing steps. Ultimately, it ensures that product quality meets drawing requirements while reducing labor and improving production efficiency.

[0069] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
