Problems solved by technology

[0003] At present, the positioning of the welding jig of the automobile body-in-white is mainly performed by a positioning mechanism with a prismatic positioning pin. The positioning method of the prismatic pin is difficult to ensure accuracy, which will eventually affect the welding accuracy. The overall structure of the positioning mechanism is complex and the flexibility is poor.

Embodiment Construction

[0010] Such as figure 1 Shown: 12 is bearing, and 11 is cylinder. The outer end of the piston rod matched with the cylinder 11 is connected with a positioning pin 8, and the positioning pin 8 is a cylindrical structure, that is, the cross section of the positioning pin 8 is circular.

[0011] A fine-tuning sliding mechanism is provided between the support 12 and the cylinder 11. The structure of the fine-tuning sliding mechanism is that a vertical fixed plate 2 is fixed on the support 12 by bolts, and a sliding plate is set between the fixed plate 2 and the moving plate 13. Rail slider type sliding connector, the sliding connector includes a slide rail 14 fixedly connected to the fixed plate 2 and a slider 1 that matches the slide rail 14 and is fixedly connected to the moving plate 13, the sliding connector has two groups and The downward direction is arranged in parallel.

[0012] The two sides of the upper part of the mobile plate 13 are connected with moving blocks 6, th...

Abstract

The invention discloses a positioning structure for a white car body welding production line. The positioning structure for the white car body welding production line comprises a supporting base and an air cylinder, a positioning pin is connected with an outer end head of a piston rod and the piston rod matches with the outer end head of the air cylinder, the positioning pin is in a cylindrical structure, and a fine adjustment sliding mechanism is arranged between the supporting base and the air cylinder. Positioning accuracy of the cylindrical positioning pin is guaranteed, the positioning pin is accurate and firm, the motion is flexible and reliable, and the whole structure is simple.

Description

technical field [0001] The invention relates to a positioning structure, in particular to a positioning structure used in a production line for welding and assembling automobile bodies in white. Background technique [0002] In the automobile manufacturing industry, the quality requirements for various parts of the automobile are getting higher and higher, and the positioning accuracy requirements for the body-in-white parts on the automobile welding production line are also becoming more and more stringent. [0003] At present, the positioning of the welding jig of the automobile body-in-white is mainly performed by a positioning mechanism with a prismatic positioning pin. The positioning method of the prismatic pin is difficult to ensure accuracy, which will eventually affect the welding accuracy. The overall structure of the positioning mechanism is complex and the flexibility is poor. . Contents of the invention [0004] The purpose of the present invention is to prov...
