Assembly error-proof device and method

Abstract

The invention relates to an assembly error-proof device and method. The assembly error-proof device comprises a supporting seat, a first limiting stop and a detecting pin. The detecting pin is rotationally connected to the supporting seat through a rotary shaft. One end of the detecting pin is connected to the rotary shaft, and the other end of the detecting pin is provided with a cantilever. Thedetecting pin can rotate around the supporting seat. The first limiting stop is mounted on the supporting seat and used for limiting the detecting position of the detecting pin in the detecting state.During assembly, the detecting pin is inserted into an open hole of a workpiece correspondingly to achieve error-proof detecting. According to the assembly error-proof device and method, the error-proof function during workpiece assembly is achieved through the simple structural design, assembly operation is not influenced, after the assembly operation is completed, the workpiece can be transported away directly, and thus, tedious tool dismounting work is avoided; and meanwhile, after the workpiece is transported away from a station, the detecting pin can further automatically fall and returnto the detecting position, manual homing is not needed, and thus the problem of using omitting due to personnel negligence is eliminated thoroughly.

Description

technical field [0001] The invention relates to an error prevention device, in particular to an assembly error prevention device and an assembly error prevention method. Background technique [0002] The bogie is one of the most important components of a rolling stock, and the welded frame, as the skeleton of the bogie, has very strict quality requirements. The two ends of the side beam of the core component are assembled and welded by the shock absorber seat (left), (right) and the beam body of the side beam. Since the overall structure of the shock absorber seat (left) and (right) is exactly the same, the difference between the two The difference is only in the symmetry of the eyelets. When assembling the side beams, it is easy for employees to confuse the two and cause quality problems of assembly errors, which are difficult to find and cause major quality problems in the subsequent driving process. Contents of the invention [0003] The main technical problem to be so...
