Special purpose machine tool for mounting piston copper bush

Abstract

The invention relates to a special purpose machine tool for mounting a piston copper bush. The machine tool comprises a lathe bed and a pre-positioning mechanism, wherein the pre-positioning mechanism is arranged in the middle of the lathe bed and slides along a longitudinal slide rail. A clamping mechanism is arranged above the pre-positioning mechanism, an angular positioning mechanism is arranged on one side of the longitudinal slide rail at the back of the lathe bed, and two sets of mechanisms which are used for mounting the piston copper bush by the machine tool are symmetrically arranged on both sides of the longitudinal slide rail in front of the lathe bed, wherein the two sets of the mechanisms which are used for mounting the piston copper bush by the machine tool can slide along a transverse slide rail. An electrical control system for controlling operations of various mechanisms is further arranged. The machine tool provided in the invention is applied in a technical field of manufacture of internal combustion engine components. The special purpose machine tool for mounting the piston copper bush provided in the invention has the following advantages of convenient adjusting and fast motion during use, and is capable of rapid installation of the copper bush. With the machine tool, precision of the mounting position of the copper bush is guaranteed. With installation of the piston copper bush by using the machine tool, yield can be improved by 50%, and efficiency of the machine tool is 3-5 times the efficiency of handwork or utilization of auxiliary tools to assistantly mounting the piston copper bush.

Description

technical field [0001] The invention relates to the technical field of manufacturing internal combustion engine parts, in particular to a special machine tool for quickly inlaying copper sleeves of pistons. Background technique [0002] The piston is an important component of the internal combustion engine. Known as the "heart" of the internal combustion engine. The piston bears repeated alternating mechanical and thermal loads under the conditions of high temperature, high pressure and high speed. With the continuous improvement of engine power, higher requirements are put forward for the wear resistance and bearing capacity of the piston pin hole. Copper is a wear-resistant material. Using copper sleeves inlaid on the inner wall of the piston pin hole can improve the wear resistance of the piston pin hole. and bearing capacity to prevent engine failure caused by pin seat cracking. In the past, in the processing of the copper sleeve inlaid with the piston pin hole, the c...
