Cylinder sleeve inner hole processing clamp

Abstract

The invention relates to a cylinder sleeve inner hole processing clamp. The cylinder sleeve inner hole processing clamp comprises a clamp main body which is composed of a metal cylindrical housing andan ultrathin metal barrel, wherein two openings of the metal cylindrical housing are symmetrically equipped with circular ring baffle plates; the outer diameters of the circular ring baffle plates are fixedly connected with the metal cylindrical housing; the ultrathin metal barrel is fixedly connected to the inner diameters of the circular ring baffle plates; the inner cavity of the ultrathin metal barrel is equipped with a cylinder sleeve; the outer part of the ultrathin metal barrel is wound with a plastic material; the two ends of the plastic material are fixedly connected to sides of thecircular ring baffle plates; the bottom of the metal cylindrical housing is connected with a base; the bottom of the base is fixedly connected with a supporting plate through a screw; and piston barrels are symmetrically arranged at the two sides of the metal cylindrical housing. The cylinder sleeve inner hole processing clamp is simple in structure, is reasonable in design, can prevent the cylinder sleeve from being deformed and worn in a processing process, also can accurately position, reduces a rejection rate, improves production efficiency, can process cylinder sleeves of different specifications, can perform thick boring and fine boring, and reduces the cost.

Description

technical field [0001] The invention relates to a jig for processing the inner hole of a cylinder liner, which belongs to the technical field of mechanical processing. Background technique [0002] Engine cylinder liner machining is divided into rough boring, rough turning, total length cutting, semi-finish hinge, semi-finish turning, fine boring, finish turning shoulder, grooving, finish turning outer circle, honing and other processes. The inner circle of the inner circle is used as the benchmark of the subsequent finishing outer circle process, which requires high shape accuracy and position accuracy, so the fine boring process is the key connecting process. The process requires that the roundness error of the inner circle of the fine boring should be less than 0.03, and the coaxiality error of the inner circle and the upper and lower belts should be less than 0.1, so as to ensure the size and shape accuracy of the next outer circle finishing process. At the same time, b...

Problems solved by technology

At the same time, because the honing allowance of the inner circle of fine boring is only about 0.05, the roughness of the inner circle is very high, and the amount of cutting tool is very small, so its efficiency has not been improved, making the fine boring process a stuck process , In the traditional technology, claws are generally used to fix. During this processing method, it is easy to cause uneven force on the outside of the cylinder liner and deform it into a waste product. At the same time, fine boring and rough boring cannot be processed on the same fixture, and they must be divided into two fixtures. Higher cost, therefore, needs further improvement
