A restraint device for engine shaft parts

Abstract

The invention discloses a constraint device of an engine shaft part, The restraining device of the engine shaft part comprises a hoop ring, a through hole is formed in the hoop ring, an end face of one end of the hoop ring is a plane, and the hoop ring is provided with a plurality of clamping devices; each clamping device comprises a pressing plate, a sliding block, an elastic piece and a first bolt, wherein deformation sections are further arranged in the middles of the elastic pieces, a hole channel is formed in the hoop ring, the sliding blocks are partially located in the hole channel, andthe sliding blocks can slide along the hole channel; the pressing plate is fixed at one ends, close to the through hole, of the sliding blocks, one ends of the elastic pieces are fixed to one ends, far away from the through hole, of the sliding blocks, and the other ends of the elastic pieces are fixedly connected with the hoop ring; and a first bolt is in threaded connection with the hoop ring,one end of the first bolt extends into the hole channel, and the end part of the first bolt extending into the hole channel acts on outer convex sides of the deformation sections. According to the constraint device, the relation between the axis of the shaft part and the axis of the constraint device can be conveniently controlled.

Description

technical field [0001] The invention relates to the technical field of automobile and motorcycle engine manufacturing, in particular to a constraining device for engine shaft parts. Background technique [0002] In the prior art, along with the development of my country's economy, society's demand for automobiles and motorcycles and the amount of automobiles and motorcycles on the market gradually increase. At the same time, my country's automobile manufacturing technology has also developed rapidly. Engines for automobiles and motorcycles generally include crankshafts, connecting rods, pistons, cylinders, intake ports, intake valves, fuel injectors, exhaust valves, exhaust ports and housings. Among these parts, there are shaft parts on the connecting rod, piston, intake valve and exhaust valve. [0003] For the manufacture of the above-mentioned shaft parts, the existing manufacturing process includes related dimension forming process, welding process, electroplating proc...
