Description

Clamp for processing piston ring

Technical Field

The utility model relates to a piston ring production and processing technology field especially relates to an anchor clamps for processing piston ring.

Background

The piston ring is a metal ring embedded in the piston groove and is divided into two types, namely a compression ring and an oil ring. The compression ring can be used for sealing the combustible mixed gas in the combustion chamber; the oil ring is used to scrape off the excessive oil on the cylinder. The piston ring is a metal elastic ring having a large outward expansion deformation, which is fitted into a ring groove having a cross section corresponding thereto. The reciprocating and rotating piston rings form a seal between the outer circumferential surface of the ring and the cylinder and one side of the ring and the ring groove by means of a pressure difference of gas or liquid. The piston ring is in production and processing process, need polish to the surface of piston ring to get rid of the burr on its surface, under prior art, when polishing the piston ring, because the volume of piston ring is less, and thickness is thinner, is difficult to fix the piston ring, thereby is difficult to polish it, influences its efficiency of polishing, consequently, we have provided a anchor clamps for processing piston ring and have solved above-mentioned problem.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the existing anchor clamps that are used for processing the piston ring that exist among the prior art when polishing the piston ring because the volume of piston ring is less, and thickness is thinner, is difficult to fix the piston ring to be difficult to polish to it, influence its shortcoming of efficiency of polishing, and the proposed.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides an anchor clamps for processing piston ring, includes the base, the vertical welded fastening in upper end of base has first splint, one side of first splint is provided with second splint, second splint slidable mounting be in on the base, first splint are kept away from one side of second splint is fixed with the fixed block, welded fastening has the connecting axle on the fixed block, the connecting axle runs through in proper order first splint, second splint, and the outer end of connecting axle rotates and installs the cam handle, the connecting axle with sliding fit between the second splint.

Preferably, the upper end screw fixation of base has the forked tail slide rail, the spout rather than the looks adaptation is seted up to the bottom of second splint, second splint slidable mounting be in on the forked tail slide rail.

Preferably, one end of the dovetail slide rail, which is far away from the first clamping plate, is fixed with a limiting block.

Preferably, the first splint with be provided with the spring between the second splint bottom, the one end welded fastening of spring is on first splint, and the other end welded fastening of spring is on the second splint.

Preferably, the arc-shaped fixing grooves are formed in the side, close to each other, of the upper end of the first clamping plate and the upper end of the second clamping plate.

The utility model has the advantages that:

drive the second splint through the spring and be close to first splint to in tentatively fix the piston ring, and through rotating the cam handle, by the protruding department extrusion second splint of cam handle, make the second splint be close to first splint direction on the forked tail slide rail, thereby make the piston ring fixed, be convenient for polish it, be convenient for to the fixed of piston ring with dismantle, the operation is convenient, the practicality is strong.
