Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of splicing tooling, and particularly relates to a double-layer double-parallel frame splicing tooling BACKGROUND

[0002] Tooling, i.e. process equipment: refers to various tools used in the manufacturing process. When preparing a profile into a certain frame structure, the profiles need to be clamped and fixed by using tooling fixtures, and then the point welding splicing work between the profiles is realized, and then the profiles are taken out from the tooling. The long strip type welding connection is fixed by using machines or manual work.

[0003] Generally, the frame splicing is mostly only in a horizontal plane, and the frame profiles are spliced and positioned based on the bottom surface of the tooling. The positioning seat and clamping components of the tooling are used to position and clamp the frame.

[0004] Most of the existing splicing tooling can only be positioned based on the tooling. However, in order to facilitate mass production, some existing double-layer combined connection type frame structures are first welded in the tooling, and then transferred to another tooling for splicing and combined welding. However, such a form cannot be used to weld the frame structure which is fixed by the upper and lower double-layer frames. In addition, the tooling for the upper and lower stacked frames not only needs to be accurately and firmly positioned and clamped, but also needs to have enough space to place the corresponding clamps of the upper frame. Therefore, the structure of the lower clamp needs to be simplified, reasonably planned, and quickly positioned and fixed. In addition, the position arrangement of the upper clamp and the displacement interference of the clamping components also need to be reasonably planned.

[0005] Therefore, a double-layer frame splicing tooling which can not only be accurately positioned and clamped, but also be easily assembled, and the clamping process and the welding process are not interfered with, is needed. SUMMARY
