Pressure maintaining safety detection linkage mechanism

Abstract

The invention relates to the technical field of automobile production equipment, and particularly relates to a pressure maintaining safety detection linkage mechanism. The pressure maintaining safetydetection linkage mechanism overcomes the defects in the prior art. The pressure maintaining safety detection linkage mechanism comprises a base and a hub, wherein a fixing base and a base plate whichare distributed in a triangular shape are fixed to the top of the base through countersunk bolts in sequence; a rotary shaft is rotationally installed on the fixing base; an air pressure pipeline loop is closed through a valve plug and an O-shaped ring, and the pressure is kept at 0.4Mpa; then, after an air path pressure sensor senses the air path pressure, a logic signal is transmitted to a starting circuit, and then detection or machining equipment is started; when the position of the hub vibrates and deviates, due to the fact that the normal pressure is kept in the air pressure pipeline loop, the valve plug is jacked up under the action of the normal pressure, the air path pressure sensor can sense pressure changes, and then the position deviation of the hub is judged; and then the starting circuit is cut off, misoperation is avoided, the machining and detection precision of an automobile can be effectively guaranteed, and the rate of finished products is remarkably increased.

Description

technical field [0001] The invention relates to the technical field of automobile production equipment, in particular to a pressure-holding safety detection linkage mechanism. Background technique [0002] The hub is also called the rim. According to the characteristics and requirements of different models, the surface treatment process of the wheel hub will also adopt different methods, which can be roughly divided into two types: baking paint and electroplating. The appearance of the wheels of ordinary models is less considered. Good heat dissipation is a basic requirement. The process is basically treated with baking paint, that is, spraying first and then electric baking. The cost is relatively economical and the color is beautiful and lasts for a long time. Even if the vehicle is scrapped , the color of the wheel remains unchanged. [0003] The detection and processing accuracy of the wheel hub is extremely high. At present, when the wheel hub is inspected or processe...

AI Technical Summary

Problems solved by technology

[0003] The detection and processing accuracy of the wheel hub is extremely high. At present, when the wheel hub is inspected or processed, the vibration offset sometimes occurs after the wheel hub is fixed. Due to the small vibration amplitude and small offset, it is difficult to detect and process It is detected by personnel during the process, so the equipment will continue to process the hub, which reduces the detection or processing accuracy of the hub, which in turn affects the yield of the hub, and is also prone to false detection
