A kind of automatic piston ring trimming machine

Abstract

The invention discloses an automatic gap grinding machine for piston rings. The automatic gap grinding machine is composed of gap grinding machine adjusting stands, a machine body, a bedplate, a machine tool electric control device, a horizontal feeding device, a pushing device, a grinding head device, a gap grinding mold and a receiving device. The bedplate and the machine tool electric control device are fixed on the machine body. Automatic operation of the gap grinding machine from feeding, pushing, pressing and head grinding to receiving is realized. According to the technical scheme, the piston rings with the gaps opening upwards are subjected to feeding in a horizontal-hanging type numerical-control pushing mode, manual arranging and centering are omitted, precise positioning can be achieved during pushing, stability and reliability are achieved during pressing, production efficiency is improved, cost is lowered, and machining precision and machining quality of the pistons are guaranteed.

Description

technical field [0001] The invention belongs to processing equipment for piston rings on automobiles, in particular to an automatic piston ring repairing machine. Background technique [0002] During the processing of piston rings for automobiles, the piston rings to be processed are generally loaded first, and then the piston rings to be processed are pushed forward to the designated position, and then the piston rings are pressed into the piston rings for repair. In the equipment of the mouth, the mouth is repaired. After the mouth repair is completed, the finished piston ring is transferred to the finished product box by the material receiving device. At present, in the process of piston ring feeding, the current general method is to adopt the method of inclined feeding, vertical feeding and pushing plate. The problem of poor reliability and low ability to adapt to varieties is likely to cause the wear of the piston ring during the feeding process and the problem of stra...

AI Technical Summary

Problems solved by technology

At present, in the process of piston ring feeding, the current general method is to adopt the method of inclined feeding, vertical feeding and pushing plate. The problem of poor reliability and low ability to adapt to varieties is likely to cause the wear of the piston ring during the feeding process and the problem of straining the end face of the piston ring. In addition, the opening of the piston ring must be turned over manually before feeding. Different piston rings Different positioning needs to be replaced, which increases labor costs; in the process of piston ring pushing, the pushing methods currently used in the world include horizontal thin plate pushing, vertical compound pushing and pneumatic split ring rotating pushing The plate pushing method, these kinds of pushing methods are not accurate, the precision is poor, and it is easy to cause the end face of the piston ring to be strained, and the failure rate is high

When pressing the material, it is difficult to control the pressing speed and the feeding distance at will, and the stability is poor during the pressing process; when the piston ring is repaired, when the grinding head rotates at high speed, the grinding head in the existing equipment The shaft is difficult to ensure stable support operation, and the machining accuracy of the piston ring opening gap is difficult to meet the requirements

Therefore, the piston ring processing equipment currently on the market has many defects. When repairing the piston ring, the precision is poor and the operation is unstable. It is difficult to guarantee the processing accuracy of the piston ring, which affects the processing quality of the piston ring.
