Embodiment Construction

[0010] The fixture used in the honing process is shown in the figure, the base (1) and the clamp body (7) can be fastened and connected with bolts, and the lower rubber bushing (2) and the upper rubber bushing (5) are installed on the lower bushing (3) and the upper bushing (3) respectively. On the bushing (6), there is a spacer ring (4) and a gland (8) to form a closed cavity at the same time, and the cylinder liner (9) is placed in the inner cavity of the lower rubber sleeve (2) and the upper rubber sleeve (5). Honing adopts rough honing and fine honing. The function of rough honing is to remove the machining allowance of the inner hole and eliminate the cylindricity error of the inner hole in the previous process. The rough grinding is made of diamond grit, the number of mesh is 180 mesh, and the processing pressure is 1.4Mpa. The double-feed honing head is used for fine honing, the double-feed coarse honing grinding rod is diamond 150 mesh, the pressure is 0.8-1.0Mpa, the ...

Abstract

The invention relates to a high-precision internal grinding processing procedure. A clamp which is used for a honing procedure of a technology of the high-precision internal grinding processing procedure is as shown in the figure that a base (1) and a clamp body (7) are connected in a fastening mode through bolts, a lower rubber sleeve (2) and an upper rubber sleeve (5) are respectively installed on a lower bush (3) and an upper bush (6), and meanwhile a closed chamber is formed by a space ring (4) and a gland (8), and a cylinder sleeve (9) is placed in inner chambers of the lower rubber sleeve (2) and the upper rubber sleeve (5). Honing adopts rough honing and fine honing. The rough honing adopts an adamas sanding belt, wherein the mesh number of the sanding belt is 180, and machining pressure of the sanding belts is 1.4 Mpa. The fine honing adopts a double feeding honing head. The mesh number of an adamas sanding belt of the double feeding honing head is 150, and machining pressure of the adamas sanding belt of the double feeding honing head is 0.8-1.0 Mpa. A particle size of a silicon carbide sanding belt adopted by the double feeding honing head is 400, and honing pressure of the silicon carbide sanding belt adopted by the double feeding honing head is 0.5 Mpa. Space cylinder sleeve machining is alternate machining of corotation and inversion, and parameters of inner bore cobwebbing are kept that Rpk is smaller than 0.25 micrometer, Rvk is equal to 1.0-2.0 micrometers, and Rk is equal to 0.4-1.2 micrometers.

Description

Technical field [0001] The invention relates to a honing process for the inner hole of a cylinder liner, in particular to a high-precision platform honing process for the inner hole of the cylinder liner. Background technique [0002] The cylinder liner is the core part of the engine, but the traditional honing process and tooling configuration cannot guarantee the dimensional accuracy, shape accuracy and surface quality of the inner hole of the cylinder liner. With the increase of society's requirements for automobile emissions, it cannot meet the requirements of product design. Contents of the invention [0003] The invention provides a new platform honing process, which can ensure the quality requirements of the product and meet the requirements of the engine's emission and power. [0004] The technical method adopted by the present invention to solve the technical problem is to use outsourcing honing fixtures, specific sand bars and special honing technical parameters ...
