Machine for automatically milling gap of piston ring

Abstract

The invention provides a machine for automatically milling a gap of a piston ring. The machine comprises a panel (1) as well as a feeding assembly (2), a loading assembly (3), a pressing assembly (4) and a guiding and positioning assembly (5) which are arranged on the panel (1), wherein the loading assembly (3) is arranged between the feeding assembly (2) and the guiding and positioning assembly (5), and the pressing assembly (4) is arranged in the middle of the guiding and positioning assembly (5). The machine for automatically milling the gap of the piston ring is convenient to operate, the labor intensity is small, the production efficiency is greatly improved, and the product quality is guaranteed.

Description

technical field [0001] The invention belongs to the field of bearing production equipment, in particular to an automatic milling and lapping machine for piston rings. Background technique [0002] Piston ring is one of the key parts of automobile engine. During the manufacturing process, there is a milling process, that is, a platform is processed on both sides of the opening. The shape is shown in figure 1 shown. The size, thickness, and symmetry of the piston ring milling opening must not only conform to the installation process, but also take into account the sealing performance of the piston ring in the engine cylinder liner to prevent air leakage, blow-by, and early wear. [0003] The processing of the piston ring seam has always been in the traditional processing mode in the industry, that is, using a small milling machine for semi-manual processing, so the positioning accuracy of the workpiece is low, the size of the machined seam is not well controlled, and the unif...

AI Technical Summary

Problems solved by technology

[0003] The processing of the piston ring seam has always been in the traditional processing mode in the industry, that is, using a small milling machine for semi-manual processing, so the positioning accuracy of the workpiece is low, the size of the machined seam is not well controlled, and the uniformity is poor, and the labor of the operator too strong

Domestic piston ring special machine manufacturers have been working hard to develop new automatic piston ring milling and lapping equipment, but due to many technical problems that are difficult to solve, there is no mature special machine product at present.
