[0002] The nose-shaped piston ring is a commonly used part in the engine piston ring. For the processing of the nose-shaped groove on the nose-shaped piston ring, the traditional processing method is to fix the single-piece nose-shaped piston ring with a clamp on the chuck of the lathe, and manually feed the tool To process the nose groove, this processing method has low production efficiency and can only process one piece at a time. At the same time, the size of the nose groove is difficult to control, resulting in many waste products, resulting in increased production costs, which is not conducive to industrial mass production. Therefore, for the nose groove The special fixture for piston ring processing is the key to solving the problem

Embodiment Construction
[0009] Such as figure 1 As shown, the fixture for processing the nose-shaped piston ring of the present invention is fixed with a pressure plate 5 at one end of the shaft 4, and the other end of the shaft 4 is movable to cover the pressure plate 5, and the processed nose-shaped piston ring is clamped between the two pressure plates 5. 3. Use the fixed nut 6 to fix the movable sleeve pressing plate 5, and fasten the nose-shaped piston ring 3 of the workpiece between the two pressing plates 5, so as to facilitate the cutting process of the turning tool 2 of the machine tool. There is a positioning hole 7 at the center of both ends of the shaft 4, and the machine tool top dust 1 is respectively inserted into the positioning hole 7 at the center of both ends of the shaft 4, and the nose-shaped piston ring 3 of the workpiece is positioned on the machine tool. 2 The nose groove on the nose piston ring 3 is processed, and the fixture is fixed by the self-equipped top of the CNC machi...

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.
