Problems solved by technology

[0004] The present invention designs an anti-error mechanism for automobile welding fixtures, which solves the technical problem that in the existing automobile welding process, the parts directly contact the lever valve in the anti-error mechanism, and the probability of damage to the lever valve caused by this contact If it is very large, it will cause the error prevention effect of the lever valve to fail, resulting in the occurrence of error events

Embodiment Construction

[0025] Combine below figure 1 and figure 2 , the present invention is further described:

[0026] The error prevention mechanism of the automobile welding jig of the present invention includes a positioning pin 1 , a first connecting plate 2 , a second connecting plate 3 , a lever valve 8 and a spring 9 .

[0027] Locating pin 1 is free to set and process according to the required length of the link mechanism. Assemble the Z-direction adjustment of the first connecting plate 2 and the Y-direction adjustment of the second connecting plate 3, then assemble the spring 9 and the bearing in the telescopic hole of the first connecting plate 2, and install the positioning pin 1 from the top Into the telescopic hole, the position of the lever valve 8 and the base position of the positioning pin 1 can be adjusted in the Z direction and the X direction through the connecting plate.

[0028] Compared with the anti-error mechanism of the traditional automobile welding fixture, the ant...

Abstract

The present invention relates to an error-proofing mechanism of an automobile welding fixture. The error-proofing mechanism comprises a positioning pin (1) and a lever valve (8). The error-proofing mechanism is characterized in that: an automobile welding part opens the lever valve (8) through the positioning pin (1). The error-proofing mechanism of the automobile welding fixture in present invention no longer uses the part to directly contact the lever valve, but uses a positioning pin contact method to control the lever valve. Direct contact between the part and the lever valve is converted into indirect contact such that protection of use of the lever valve can be achieved.

Description

technical field [0001] The invention relates to an error prevention mechanism, in particular to an error prevention mechanism for an automobile welding fixture. Background technique [0002] In the automobile manufacturing industry, the application of error proofing technology is very common. The production of automobiles needs to weld thousands of parts to form the body-in-white of the car. These parts are large and small, and errors may occur at any time during the entire welding process. To solve such problems, some error prevention is often done on the welding fixture mechanism, but the current type of error-proofing uses the lever valve through air interlocking. The contact method of the error-proofing mechanism is that the parts are in direct contact with the lever valve. This kind of contact has a very high probability of damage to the lever valve. It will lead to the failure of the anti-error effect of the lever valve, resulting in the occurrence of error events. F...
