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

The invention discloses a detection tool for detecting the deformation degree of a circular cylinder. The detection tool comprises a detection table, a left fixing column, a right fixing column, two plug gauges, a reference flat plate, three displacement sensors and a PLC (programmable logic controller). An arc-shaped reference groove capable of containing the cylinder is formed in the detection table. The height of a left telescopic cross rod is equal to the height of a right telescopic cross rod, and the height of the two telescopic cross rods is equal to the height of the cylinder placed in the arc-shaped reference groove. Each plug gauge is matched with the inner hole of the cylinder. The reference flat plate is arranged right above the arc-shaped reference groove. Three displacement sensors, which are connected with the PLC, are sequentially arranged at the bottom of the reference flat plate from left to right. The connecting line of the three displacement sensors is parallel to the length direction of the arc-shaped reference groove. According to the technical scheme of the invention, during the detection process, the displacement sensors are not in direct contact with the cylinder body of an oil cylinder, thus being long in service life. Meanwhile, the generation of scratches on the surface of the cylinder body of the oil cylinder is avoided. The detection tool is high in detection accuracy, high in detection rate, convenient in detection and capable of automatically reading.
Description
technical field [0001] The application relates to an auxiliary inspection device in the production process of an oil cylinder, in particular to a detection tool for the degree of deformation of a circular cylinder. 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 analysis.
