Abstract
The invention relates to the mechanical machining technical field, particularly to a clamp for machining a nose-shaped piston ring. A pressing plate 5 is fixedly arranged at one end of a shaft 4; a pressing plate 5 is flexible arranged at the other end of the shaft in a sleeving mode; a machining part nose-shaped piston ring 3 is arranged between the two pressing plates 5 in a clamped mode; the flexible sleeving pressing plate 5 is fixed through a fixing nut 6; the center of each end of the shaft 4 is provided with a positioning hole 7; each positioning hole 7 which is formed at the corresponding end of the shaft 4 is ejected into a machine tool tip 1 to be positioned. According to the clamp for machining the nose-shaped piston ring, the clamp is fixed through the self-assembled tips of a numerical control machine tool, a plurality of pieces of products can be machined simultaneously through the numerical control programming, and accordingly the automatic feeding of cutting is implemented and meanwhile the size of a nose-shaped groove can completely conform to the technical requirements of the products due to the automatic compensation effect of a numerical control system and accordingly the rejection rate drops to 5% from 35% and the production efficiency is improved by more than 5 times.
Description
Technical field
The present invention relates to Machining Technology field, particularly a kind of fixture of processing nose shape piston ring.
Background technology
Nose shape piston ring is a kind of part conventional in engine piston ring, for the processing of nose shape groove on nose shape piston ring, traditional diamond-making technique is the fixing monolithic nose shape piston ring of fixture adopting on lathe dog, by manual feed, nose shape groove is processed, this processing mode production efficiency is low, can only process one at every turn, nose shape groove size is difficult to control simultaneously, generation waste product is many, cause production cost to increase, be unfavorable for industrialized mass production, so be the key of dealing with problems for the special fixture of nose shape piston ring processing.
Summary of the invention
The object of the present invention is to provide one simple in structure, cost is low, the fixture of the processing nose shape piston ring that production efficiency is high.
The object of the invention is to realize by following approach: the fixture of processing nose shape piston ring is, in one end of axle 4, pressing plate 5 is fixedly housed, at the other end movable set pressing plate 5 of axle 4, between two block pressur plates 5, clamp workpiece nose shape piston ring 3, with the fixing movable set pressing plate 5 of hold-down nut 6, have locating hole 7 in the center, two ends of axle 4.The locating hole 7 at described axle 4 two ends is to withstand on respectively wherein location by lathe top dirt 1.
The present invention processes the good effect of the fixture of nose shape piston ring: utilize the top of Digit Control Machine Tool autogamy that fixture is fixed, pass through numerical control programming, can process by logarithm flake products simultaneously, realize the auto-feed of cutting, while is due to the auto-compensation effect of digital control system, make the size of nose shape groove meet product technology requirement completely, percent defective drops to 5% by original 35%, and production efficiency improves more than 5 times.
