Description

Technical Field

[0001] This utility model belongs to the field of welding processing technology, and in particular relates to a guide rail parallelism welding positioning tool. Background Technology

[0002] The existing structure of a certain part is as follows Figure 1 As shown, its structure is relatively complex and has two guide rails welded on. This part has high requirements for the spacing and parallelism of the two guide rail surfaces. The current process is to process the two guide rail surfaces after welding to ensure their spacing and parallelism. However, due to the special structure of the part, this method has high processing cost and low processing efficiency, and cannot meet the on-site production needs of the product. Utility Model Content

[0003] The technical problem this invention aims to solve is that processing the two guide rail surfaces after welding results in high processing costs, low processing efficiency, and an inability to meet the on-site production requirements of the product.

[0004] To solve the above-mentioned technical problems, the specific technical solution of this utility model is as follows:

[0005] A guide rail parallelism welding positioning tool includes a support rod 1 and two positioning blocks 2. The bottom side of the positioning block 2 is set as a positioning surface, and the two positioning blocks 2 are arranged side by side. The positioning surfaces on the two positioning blocks 2 respectively cooperate with the guide rail grooves of the two guide rails. The two ends of the support rod 1 are fixedly connected to the upper ends of the two positioning blocks 2 respectively.

[0006] Furthermore, the support rod 1 is welded to the positioning block 2.

[0007] Furthermore, the length of the support rod 1 is the same as the distance between the two guide rails.

[0008] Furthermore, the bottom cross-section of the positioning block is a convex structure, and its two sides are positioning surfaces.

[0009] Furthermore, the fit clearance between the positioning surface and the guide rail groove is between 0.01 and 0.03 mm.

[0010] Furthermore, two sets of positioning tools are used together and are respectively set at both ends of the guide rail.

[0011] This utility model has the following advantages: by using the guide rail groove of the part for positioning, the distance and parallelism requirements of the two guide rail grooves can be guaranteed directly after welding. Only the upper surface of the guide rail needs to be machined after welding, which reduces the production cost. Attached Figure Description

[0015] To better understand the purpose, structure, and function of this utility model, a more detailed description of this utility model is provided below with reference to the accompanying drawings.

[0016] like Figure 2-Figure 3 As shown, the guide rail parallelism welding positioning tool of this utility model includes a support rod 1 and a positioning block 2. The upper ends of the support rod 1 and the positioning block 2 are fitted together and welded. The two sides of the lower end boss of the positioning block 2 are respectively fitted with the two sides of the guide rail groove of the part, with the fitting clearance controlled between 0.01-0.03mm. During welding, the two sets of positioning devices are placed at both ends of the guide rail to fix the relative positions of the two guide rails, which can ensure the spacing and parallelism requirements of the two guide rails after welding. After welding, only the upper surface of the guide rail needs to be machined to meet the product requirements. This effectively reduces the production cost of the product.

[0017] Although the embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and improvements without departing from the principles of the present invention, and these modifications and improvements should also be considered to fall within the protection scope of the present invention.
