Abstract

A camshaft oil hole plug pressure resistance testing device is characterized in that it includes a base plate and a pressure test rod, the base plate is provided with a camshaft positioning device and a detection oil cylinder, and the length of the pressure test rod is the same as that of the cam The length of the shaft is matched, and the detection cylinder is equipped with a pressure sensor and a position sensor connected with the PLC. The data collected by the PLC is used to determine whether the pressure resistance performance of the camshaft oil hole plug is qualified. The invention has the advantages of simple structure, safe and convenient operation, more than 2 times the efficacy of the traditional oil injection and pressure measurement method, high accuracy of detection results, and can avoid manual misjudgment caused by oil injection and pressure measurement.

Description

Technical field [0001] The invention relates to a detection device in the process of camshaft processing, in particular to a pressure resistance detection device for a camshaft oil hole plug. Background technique [0002] The prior art camshaft processing technology is to first process the oil passage hole, and then press-fit the plug on the shaft end. Since there is pressure oil in the oil passage hole when the camshaft is working, it is necessary to test the pressure resistance of the press-fit plug. The existing detection process is carried out by means of oil injection and pressure measurement, which is inconvenient and time-consuming. In production, there is an urgent need for a device that can facilitate the detection of the pressure resistance of the camshaft oil hole plug. Summary of the invention [0003] The problem to be solved by the present invention is to provide a camshaft oil hole plug pressure resistance detection device, which has a simple structure, convenient...
