In order to enable those skilled in the art to better understand the solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

Please refer to Figure 1 and Figure 2, Figure 1 is a schematic front view of a specific embodiment of the assembly tooling provided by the present invention for operating support after assembly; A schematic top view of a specific embodiment of the pair tooling for operation support.

The pairing tooling provided for operation support after assembly in the specific embodiment of the present invention includes a positioning plate 4, a first limiting plate 1, a second limiting plate 2 and a third limiting plate 3, wherein the first limiting plate The positioning plate 1 and the second limiting plate 2 are installed on the positioning plate 4 and the plate surface is perpendicular to the positioning plate 4, and the first limiting plate 1 and the second limiting plate 2 are perpendicular to each other. A third limiting plate 3 is arranged on the upper part of the first limiting plate 1 , the surface of the third limiting plate 3 is parallel to the positioning plate 4 , and the third positioning plate 3 has an arc-shaped notch.

When operating the support after pairing, place the surface of the bottom plate that needs to be welded with positioning pins on the positioning plate 4, put the edge of the bottom plate close to the first limiting plate 1 and the second limiting plate 2, and pass through the first limiting plate 1 The bottom plate is positioned at right angles between the second limiting plate 2. Then the positioning pin is placed on the base plate, and the positioning pin is close to the arc-shaped gap 5 on the third limiting plate 3, the position of the positioning pin is positioned, and finally welding is performed. The distance between the positioning pin and the edge of the bottom plate is determined by the vertical distance between the arc-shaped notch 5 and the first limiting plate 1 and the second limiting plate 2 .

Through the above positioning method, the grouping of the rear operation support is carried out on the same tooling, ensuring the positioning of the positioning pins, the spacing of the positioning pins, and the positioning of the pin holes on the bottom plate are accurate, meeting the needs of the product, and improving in mass production. work efficiency.

When two positioning pins need to be welded for the rear operation support that needs to be paired, two third limit plates 3 can be set according to the positions of the two positioning pins, and the opening directions of the two arc-shaped notches 5 are the same, and through the two arcs The distance between the shaped gaps 5 determines the distance between the two positioning pins, and the two positioning pins are positioned. The quantity of the third limiting plate 3 can also be set according to the needs of the actual situation, as long as the pairing of the rear operation support is ensured, it is within the scope of protection of the present invention.

In the assembly tooling provided by the specific embodiment of the present invention, two third limiting plates 3 are arranged on the upper part of the first limiting plate 1, and the third limiting plates 3 can be installed on the first limiting plate according to the size requirements 1, and the middle area of the first limiting plate 1 can be removed, thereby saving materials. The third limiting plate 3 can also be installed on the positioning plate 4, as long as the position of the arc-shaped notch 5 is correct, it is within the scope of protection of the present invention. And when the first limiting plate 1 is a whole plate, it does not affect the use of the pair of tooling, and it is also within the protection scope of the present invention.

In the assembly tooling provided by the specific embodiment of the present invention, the first limiting plate 1 and the second limiting plate 2 function to limit the position of the bottom plate, therefore, the first limiting plate 1 and the second limiting plate can be 2 are installed on two adjacent edges of the positioning plate 4. This not only ensures that the first limiting plate 1 and the second limiting plate 2 are perpendicular to each other, but also saves the material of the positioning plate 4 .
