Description

Technical Field

[0001] This utility model relates to the field of welding technology, and in particular to a welding positioning fixture. Background Technology

[0002] Welding positioning fixtures are specialized equipment or devices used in welding processes. Their core function is to achieve precise positioning and reliable clamping of weldments, thereby ensuring welding quality and improving production efficiency. Currently, existing technologies typically use measuring tapes, steel tape measures, or chalk lines to initially determine the position of parts, and then use conventional right-angle rulers and angle plates to position the parts. However, using measuring tapes and steel tape measures to determine dimensions is prone to significant deviations due to varying techniques. Furthermore, the thickness, straightness, and curvature of chalk lines can all affect the subsequent positioning of parts. Right-angle rulers and angle plates cannot reliably and stably assist in assembling and positioning parts. Therefore, we propose a welding positioning fixture. Utility Model Content

[0003] The purpose of this utility model is to solve at least one of the technical problems existing in the prior art, and to provide a welding positioning fixture that can accurately position parts without being affected by human factors. It also solves the problems of difficulty and instability in using conventional right-angle rulers and angle plates by designing a special mechanism.

[0004] To achieve the above objectives, a welding positioning fixture is provided, comprising: a base plate, wherein a recessed groove and a through hole are provided on the base plate, and a positioning post is provided in the recessed groove and the through hole, the positioning post is provided with a threaded hole, and the positioning post is connected to the base plate through the threaded hole by a bolt, the positioning post is provided with a plurality of positioning holes and part holes, and positioning pins are provided in the positioning holes and part holes.

[0005] According to the aforementioned welding positioning fixture, a pad and a nut are fitted on the positioning pin, and a plurality of positioning holes on the positioning pin are positioned in conjunction with the holes in the part by the positioning pin, and then fastened by the pad and the nut.

[0006] According to the aforementioned welding positioning fixture, the recessed groove and through hole on the substrate are used to position the positioning post, and the threaded hole on the positioning post is connected to the substrate by bolts.

[0007] According to the welding positioning fixture, a counterweight is provided on the left side of the substrate, a connecting piece is provided on the counterweight, and a connecting hole is provided on the connecting piece.

[0008] According to the welding positioning fixture, the top of the connecting piece is respectively connected to a first mating piece and a second mating piece.

[0009] The above solution has at least one of the following beneficial effects: the substrate, positioning post and positioning pin of this technical solution are convenient and simple to assemble and use, which can effectively reduce the manual assembly time. Compared with the traditional marking and layout positioning operation process, it is nearly 70% faster, and it reduces the risk of assembly errors and the inspection frequency of inspection personnel, which greatly improves production efficiency and reduces production costs.

[0010] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description
