The invention discloses a pressure tap for a hydraulic oil cylinder of an automatic machine tool. The pressure tap comprises a tap body connected to a hydraulic oil cylinder body in a screwed mode, and a first sealing rubber ring is arranged between the outer wall of the tap body and the inner wall of the hydraulic oil cylinder body. A communicating pipe and a cavity are arranged in the tap body, and the cavity is communicated with the hydraulic oil cylinder body through the communicating pipe. A pressure measuring spring, a steel ball and a pressure measuring push rod are arranged in the cavity, one end of the pressure measuring spring abuts against the communicating pipe, the other end of the pressure measuring spring is connected with the pressure measuring push rod through the steel ball, the pressure measuring push rod is embedded in the cavity, the tap body extends out of the outer end of the pressure measuring push rod, a second sealing rubber ring is arranged between the outer wall of the pressure measuring push rod and the inner wall of the tap body, and a displacement sensor is connected to the rear end of the pressure measuring push rod. According to the pressure tap, the pressure measuring spring is connected into an oil path of the hydraulic oil cylinder and pushes the pressure measuring push rod to move, displacement is set through the displacement sensor, and thus the pressure value of the hydraulic oil cylinder of the automatic machine tool is obtained; the pressure tap has good application prospects.
Description
technical field [0001] The invention relates to a pressure measuring joint used for a hydraulic oil cylinder of an automatic machine tool, belonging to the technical field of machine tool components. Background technique [0002] Hydraulic cylinders can provide power for automatic processing machine tools, so they are widely used. At present, the hydraulic cylinders on the market need external pressure measuring equipment to test the pressure of the hydraulic cylinder. When the pressure is insufficient, it is convenient to replenish oil in time to ensure reliable things. , very inconvenient to use, time-consuming and labor-intensive. Contents of the invention [0003] The purpose of the present invention is to overcome the problems of inconvenient use, time-consuming and labor-intensive use of the existing hydraulic cylinders when external pressure measuring equipment is used to test the hydraulic cylinders. The pressure measuring joint used for the hydraulic oil cylinde...
