Dried type clamp for quilting and grinding air cylinder sleeve

Abstract

The invention discloses a dried type clamp for quilting and grinding an air cylinder sleeve. The clamp comprises a fixed outer sleeve, a spring sleeve and a positioning base, wherein the fixed outer sleeve is nested in the positioning base; a spring is mounted in a spring mounting hole which is sleeved outside a lug boss below the inner wall of the fixed outer sleeve; at least one internal conical face is arranged on the inner wall of the fixed outer sleeve; the spring sleeve is mounted in the fixed outer sleeve; the lower end of the spring sleeve is arranged on the spring; the outer circumference face of the spring sleeve is provided with an external conical face matched with the internal conical face on the inner wall of the fixed outer sleeve; and a vertical opening is arranged on the spring sleeve. The inner circumference face of the fixed outer sleeve and the conical face on the outer circumference face of the spring sleeve are in compact contact so that the inner hole of the spring sleeve and the outer circumference of the air cylinder sleeve can be ensured to be in gapless contact; the machining deformation of the air cylinder sleeve is small; and the machining precision is high. Furthermore, a gap is reserved between the inner circumference face of the spring sleeve and the outer circumference of the air cylinder sleeve, so that the scrapping rate of the outer circumference face of the air cylinder sleeve is reduced and the yield is improved.

Description

technical field [0001] The invention relates to a tooling fixture for mechanical processing, in particular to a special fixture for honing the inner hole of a cylinder liner. Background technique [0002] The cylinder liner of an internal combustion engine is one of the most basic components of the engine. It forms a combustion chamber with pistons, piston rings, and cylinder heads. The mixture of gasoline (diesel) and air explodes in it to generate power, and finally drives machinery or vehicles to run. There are two types of cylinder liners: dry cylinder liners and wet cylinder liners. The cylinder liner is generally made of alloy cast iron to ensure high thermal conductivity and wear resistance. [0003] The surface of the inner hole of the cylinder liner supports the up and down movement of the piston and piston ring, so the inner hole of the cylinder liner requires high dimensional accuracy and shape accuracy. Generally, a vertical honing machine is used for the final ...

Problems solved by technology

The advantage of the accompanying sleeve is that it limits the greater deformation of the cylinder liner, but there are also disadvantages: 1) Each cylinder liner needs to be assembled and disassembled once, and due to the small gap, it is difficult to assemble and disassemble and the processing efficiency is low; 2 ) There is only a gap of about 0.05mm between the traveling sleeve and the outer circle of the cylinder liner. Although the larger deformation is limited, the deformation still exists. If the gap is too small, it cannot be loaded and unloaded; Scratch formation on round surface, resulting in scrap
