Problems solved by technology

[0002] The traditional bearing bush processing is to weld the split bearing bush as a whole and then put it on the lathe to process the inner and outer circles. After the processing is completed, boil the tin with hot water and separate them. This is inconvenient and time-consuming operation, and the work efficiency...

Embodiment Construction

[0012] The present invention includes a three-jaw chuck, a split-and-close fixture composed of two semicircular cross-sections, and a top-pressure fixture that cooperates with the outer flange of the bearing bush; The end is turned downwards to form a snap ring to clamp the outer flange of the bearing bush.

[0013] A bearing bush processing method is carried out according to the following steps:

[0014] 1) Fix the split two bearing shells with combined fixture and three-jaw chuck, and then process the inner circle and outer flange;

[0015] 2) After the inner circle and outer flange are processed, use the top pressure fixture to clamp the outer flange of the bearing bush, and then disassemble the split fixture to process the outer circle;

[0016] 3) After the machining is completed, disassemble the bearing bush from the three-grip chuck and the top-pressing fixture to complete the machining.

Abstract

The invention relates to a combination fixture used for bearing bush machining and a machining method of the combination fixture. According to the combination fixture and the machining method, through ingenious match among all fixture bodies, the purpose of changing bearing bush machining orders is achieved. According to the machining method, two bearing bushes are located through the combination fixture and a three-jaw chuck, and outer flange machining and inner circle machining are conducted. Then, the three-jaw chuck is matched with the abutting type fixture body to conduct outer circle machining, the welding step and the final split step in a traditional bearing bush machining process are avoided, and therefore deformation of the combination fixture is small, and accuracy is effectively guaranteed.

Description

technical field [0001] The invention relates to a combined fixture for bearing pad type processing and a processing method thereof, which improves the processing accuracy of the bearing pad by changing the processing sequence of the bearing pad. Background technique [0002] The traditional bearing bush processing is to weld the split bearing bush as a whole and then put it on the lathe to process the inner and outer circles. After the processing is completed, boil the tin with hot water and separate them. This is inconvenient and time-consuming operation, and the work efficiency is low. At the same time, it cannot guarantee Product quality, the reason is that during the welding process and the final cutting process, because it involves changes in heat and due to the nature of the material, there will always be a certain degree of deformation, and its accuracy will be affected to a certain extent. Contents of the invention [0003] In view of the above defects, the present...
