Abstract

The invention discloses a processing method of a low-rigidity polymer material sealing ring. Rough-turning and fine-turning the inner and outer circular surfaces of the sealing ring are carried out on a cylindrical blank; The vacuum suction cup fixture is used for positioning and clamping, and CNC programming is used to process the incision and surface structure on the end face of the sealing ring at one time. The incision and surface structure on the other end face are machined. The present invention can complete all the processing steps of one end face by one clamping and positioning, and can obtain the finished sealing ring through the processing of two stations. The clamping and processing process of the invention is simple to operate, ensures the processing efficiency, avoids multiple clamping and positioning, and improves the processing accuracy. The invention adopts a special vacuum suction cup fixture for positioning and clamping, which avoids the deformation of the sealing ring caused by the traditional mechanical clamping method, and improves the machining accuracy of the sealing ring.

Description

technical field [0001] The invention belongs to the field of mechanical processing of sealing parts, and in particular relates to a processing method of a low-rigidity macromolecular material sealing ring. Background technique [0002] Expanding ring type rotary sealing ring is an important part of the vehicle transmission. It is usually a circular ring with a rectangular cross-section and a cutout in the circumferential direction. It is installed in the annular groove on the rotating shaft and rotates tightly under the pressure of the sealing medium. Shaft and housing, to achieve the sealing effect. The diameter of the sealing ring is usually large, about tens to hundreds of millimeters, but due to the compact installation space, the difference between the inner and outer diameters and the thickness of the sealing ring are only a few millimeters, which leads to a decrease in the stiffness of the sealing ring, and improper clamping during processing is easy to produce Large...
