Detailed Description

To make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the drawings of the embodiments of the present invention are combined to clearly and completely describe the technical solutions of the embodiments of the present invention, and obviously, the described embodiments are some embodiments of the present invention, not all embodiments.

Thus, the following detailed description of the embodiments of the present invention, presented in the accompanying drawings, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 3, for the welding piece of the welding position frock that adopts this embodiment to provide, it includes square pipe 2 to and the three pairs of sheetmetal 3 of welding on square pipe 2, the cooperation side of sheetmetal 3 and square pipe 2 is provided with U type bayonet socket, sheetmetal 3 passes through bayonet socket cooperation on square pipe 2, and with both welding together.

As shown in figure 1, the welding and positioning tool comprises a positioning seat 11 and an end plate 12 which is detachably mounted at one end of the positioning seat, wherein the positioning seat 11 is of an H-shaped structure, two opposite surfaces of the positioning seat are respectively provided with a U-shaped groove, the side walls of the U-shaped grooves are respectively provided with a strip-shaped caulking groove 13, and the strip-shaped caulking grooves 13 are perpendicular to the length direction of the U-shaped grooves.

The U-shaped groove is used for placing the square tube 2, and the strip-shaped caulking groove 13 is used for positioning the metal sheet 3.

In order to fix the two ends of the metal sheet 3 and ensure the positioning stability and precision of the metal sheet 3, the strip-shaped caulking grooves 13 on the side walls of the two sides of the same U-shaped groove are oppositely arranged.

In order to increase the applicability of the welding positioning tool, the U-shaped groove comprises an upper U-shaped groove 14 and a lower U-shaped groove 15.

Specifically, in the above U-shaped groove 14 as an example, two corresponding bar-shaped grooves 13 on two side walls are used for positioning the same metal sheet 3, and two pairs of four bar-shaped grooves 13 for positioning a pair of the same metal sheets 3 are a group.

The upper U-shaped grooves 14 and the bar-shaped caulking grooves 13 on the side walls thereof are positioning portions used for applying the welded member of the present embodiment, specifically, the upper U-shaped grooves 14 are fitted with the square pipe 2, and the bar-shaped caulking grooves 13 include three sets corresponding to the positions of the three pairs of metal plates 3, respectively.
