Description

A bolt welding fixture

technical field

The utility model relates to a welding jig used in an automatic welding production line of a compressor.

Background technique

Some important equipment in the fields of petrochemical, refrigeration, medicine, solar energy, etc. need to involve high-temperature welding in the manufacture, and the fixtures used in this type of welding need to have the characteristics of high temperature resistance and high pressure resistance. At present, various terminals need to be welded on the compressor production line. Due to the lack of tools to clamp and position the parts to be welded, relative movement between parts often occurs during welding, so the operator needs to constantly adjust the position of each part. This leads to low processing efficiency, and it is also easy to cause inaccurate welding positions.

Utility model content

The purpose of the utility model is to provide a jig used for bolt welding on the compressor production line.

The technical solution adopted by the utility model to solve the technical problem is: a bolt welding jig, including a square bottom plate and a positioning ring fixed on the bottom plate through a cylindrical pin with internal thread, the bottom plate is provided with a circular opening, and the positioning ring A positioning column tangent to the circular opening is provided, and the positioning column is fastened to the bottom plate through a hexagon socket head cap screw.

The beneficial effects of the utility model are as follows: the parts to be welded are placed on the positioning ring and fixed by the positioning column, and then the outer surface of the parts to be welded or the inner surface of the parts to be welded are welded through a circular opening, and finally the bolt welding process is completed, and this jig can replace Workers realize semi-automatic welding, high processing efficiency and good welding quality.

Description of drawings

Fig. 2 is a sectional view along A-A direction in Fig. 1 .

Detailed ways

Below in conjunction with accompanying drawing, the utility model is described in further detail.

Referring to Fig. 1 and Fig. 2, the utility model discloses a bolt welding jig, which includes a square bottom plate 1 and a positioning ring 2 fixed on the bottom plate 1 by internally threaded cylindrical pins 5. The bottom plate 1 is provided with a circular Opening 4, the positioning ring 2 is provided with a positioning column 3 tangent to the circular opening 4, the positioning column 3 is tightly connected with the base plate 1 by a hexagon socket head screw 6, and the parts to be welded 7 are placed on the positioning ring 2 during processing. The positioning column 3 is fixed, and then the outer surface of the part to be welded or the inner surface of the part to be welded is welded through the circular opening 4, and finally the bolt welding process is completed. This fixture can replace workers to realize semi-automatic welding, with high processing efficiency and good welding quality.

What is described above is only the preferred embodiment of the present utility model, and it should be pointed out that for those of ordinary skill in the art, without departing from the premise of the inventive concept of the present invention, some deformations and improvements can also be made, and these all belong to Protection scope of the present utility model.
