Curvature online detection device and method for automobile part machining

Abstract

The invention discloses a curvature online detection device and detection method for automobile part machining in the technical field of automobile part machining. The device comprises a detection platform assembly which comprises an L-shaped installation platform which is provided with a detection platform body; an online detection assembly, wherein a detection frame is movably arranged on the front wall of a guide plate, a guide rail is arranged in the detection frame, and a detection disc is movably arranged in the guide rail; an alternate driving assembly which comprises a driving rod fixedly connected with the detection frame. The detection disc is in close contact with the curved surface of a to-be-detected part and slides along the curved surface of the to-be-detected part, the angle between the detection rod and a linkage rod is driven to change according to the change of the curved surface, and the curvature value of the part can be quickly obtained through positioning of a plurality of detection points; a cam drives the driving rod and the detection frame to move, a missing-tooth bevel gear and a full-tooth bevel gear are matched to enable the part to move to the detection position, the detection process is conducted in sequence, non-stop operation is achieved, and the detection efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of auto parts processing, in particular to an online curvature detection device and detection method for auto parts processing. Background technique [0002] Machining refers to the process of changing the shape or performance of a workpiece through a mechanical device. According to the difference in processing methods, it can be divided into cutting processing and pressure processing. The production process of the machine refers to the whole process of making products from raw materials. For machine production, it includes transportation and storage of raw materials, production preparation, blank manufacturing, processing and heat treatment of parts, product assembly, debugging, painting and packaging, etc. The content of the production process is very extensive. Modern enterprises use the principles and methods of systems engineering to organize and guide production, and regard the production process as a...

AI Technical Summary

Problems solved by technology

[0003] Auto parts need to be tested for curvature after processing to determine whether the quality is qualified. At present, the detection of the curvature of parts is mostly done manually or by laser. Manual detection is low in efficiency, labor-intensive, and low in accuracy. , the cost of laser detection is high, and parts need to be replaced manually, and the detection efficiency is low. Therefore, we propose an online curvature detection device and detection method for auto parts processing
