Oil cylinder ovality correction device

Abstract

The application discloses a device for correcting the ellipticity of an oil cylinder barrel, which includes a conveying track and an ellipticity correcting device; the conveying track is provided with several arc-shaped grooves parallel to each other and capable of placing the barrel of the oil cylinder. The groove is the correcting station; the length of the arc-shaped groove is less than the length of the cylinder barrel; the ellipticity correcting device includes a left sliding column, a positioning plug gauge, a correcting head, a correcting sleeve and a right sliding column; the positioning plug gauge is fixed on the On the right side of the left sliding column, the positioning plug gauge can extend into the cylinder barrel on the straightening station; the straightening head is fixed on the left side of the right sliding post, and the straightening head is cylindrical and can rotate axially; There is an orthotic sleeve inside the head, and the orthotic sleeve is also in the shape of a cylinder and can rotate freely in the radial direction; the cylinder barrel at the orthotic station can be freely inserted into the orthotic sleeve. The application can automatically correct the oil cylinders with deviations in the coaxiality, greatly improve the qualified rate of products, and reduce production costs.

technical field [0001] The application relates to an auxiliary inspection device in the production process of an oil cylinder, in particular to a device for correcting the ellipticity of the cylinder barrel of an oil cylinder.

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

[0003] The important thing is that the detected cylinders with poor coaxiality are basically discarded at present. If they can be corrected, the pass rate will be greatly improved and the production cost will be reduced.
