Cylinder coaxiality automatic detection machine with controllable compacting force

Abstract

The application discloses an automatic detection machine for cylinder coaxiality with controllable pressing force, which includes a detection table, a left fixed column, a right fixed column, two plug gauges, a reference plate, three displacement sensors, a PLC, two Arc-shaped pressure claws, pressure sensors and lifting displacement sensors; there is an arc-shaped reference groove on the detection table that can place the cylinder; each plug gauge can match the inner hole of the cylinder; the reference plate is set on the arc-shaped reference Directly above the groove, three displacement sensors are arranged on the bottom of the reference plate from left to right, and the top of each arc-shaped pressure jaw is fixedly connected with the reference plate through a lifting rod; the bottom of one of the arc-shaped pressure jaws is provided with a pressure sensor, wherein a lifting rod is provided with a lifting displacement sensor. In the detection process of this application, the displacement sensor is not in direct contact with the oil cylinder, the displacement sensor has a long service life, and will not scratch the surface of the oil cylinder, the detection accuracy is high, the detection rate is high, the detection is convenient, and it can automatically reading.

Description

technical field [0001] The application relates to an auxiliary inspection device in the production process of oil cylinders, in particular to an automatic inspection machine for cylinder coaxiality with controllable pressing force. Background technique [0002] During the production process of the oil cylinder, there is a high requirement for the coaxiality of the left and right ends of the cylinder. For a longer cylinder, deformation, ellipse or left and right misalignment are more likely to occur during production. Therefore, in the production process, it is necessary to detect the coaxiality of the cylinder. Most of the existing methods are manual visual inspection, the detection rate is low, and the detection has been missed. There is also a method of using the left and right ends of the plug gauge to carry out the plug sleeve, but the detection is cumbersome, the workload is large, and the specific data of the deformation cannot be read out, which is not convenient for ...

Problems solved by technology

[0002] During the production process of the oil cylinder, there is a high requirement for the coaxiality of the left and right ends of the cylinder barrel. For a longer cylinder barrel, deformation, ellipse or left and right misalignment are more likely to occur during production.

Therefore, in the production process, it is necessary to detect the coaxiality of the cylinder. Most of the existing methods are manual visual inspection, the detection rate is low, and the detection has been missed.

There is also a method of using the left and right ends of the plug gauge for plugging, but the detection is cumbersome, the workload is heavy, and the specific data of the deformation cannot be read out, which is not convenient for analysis
