SU1590345A1 - Arrangement for working corners of piston ring lock - Google Patents

Abstract

The invention relates to mechanical engineering and can be used to process the corners of a piston ring lock. The aim of the invention is to improve the quality of processing by eliminating the influence on the accuracy of processing, fluctuations in the size of the ring height and the calibration error of the lock. Base 1 is equipped with a rack 2, a drive 3, a loading and unloading mechanism 4 and grinding heads 5 and 6 for processing, respectively, the inner and outer corners of the lock of the piston ring 40. On the rack 2 there is a transport mechanism 8 in the form of a drum. The reference point of the piston ring has a distance between the side surfaces of the lock more than the lumen. The orientated ring 40 is clamped at the ends on the orientator with spring-loaded clamping levers and in this state leaves the orientator. At the same time, the inside corners of the lock are released and the ring is fed into the treatment area by a grinding head 5 containing a movable grinding belt lying on the forming surfaces of the shaped roller and driven by the driving and tensioning rollers. The inside corners come into contact with the working surfaces of the tape. After grinding the inner corners, a ring 40 is fed to the orientator, where it is reoriented to the outer corners of the lock, the processing of which is carried out similarly to the grinding head 6. 13 Il.
