Abstract

The invention discloses a combined pneumatic machining fixture suitable for various shaft sleeves. The shaft sleeves are double-hole shaft sleeves of a gear oil pump. The combined pneumatic machiningfixture comprises a top panel, expanding sleeves arranged on the top panel, a pull rod which is arranged internally, a tensioning cylinder arranged at the lower end of the top panel, a guide plate which is positioned between the tensioning cylinder and the top panel and is connected with the cylinder rod and the pull rod of the tensioning cylinder, and a guide column which passes through a cylindrical through hole in the guide plate and is connected with the top panel, wherein the cylinder body of the tensioning cylinder is connected with the top panel, the expanding sleeves with various sizesare installed on the top panel for clamping various types of shaft sleeves. According to the fixture, expanding sleeves with different sizes are installed on the top panel to be suitable for combinedmachining of various shaft sleeves; and through a pressing plate, the shaft sleeves can undergo positioned adjustment before clamping is completed, so that the appearance and surface machining precision of the shaft sleeves is high.

Description

technical field [0001] The invention relates to the field of shaft sleeve fixtures, in particular to a combined pneumatic machining fixture suitable for multiple varieties of shaft sleeves. Background technique [0002] The shaft sleeve is an important part of the gear oil pump (motor). The double pump needs 4 shaft sleeves, and the triple pump needs 6 shaft sleeves. With the wide application in the field of hydraulic technology, the gear oil pump market continues to expand, and the demand for shaft sleeves grows rapidly. Traditional shaft sleeves have many processing procedures, long production lines, poor product quality stability, single types of jig processing shaft sleeves, and low production efficiency. As a result, it is difficult to greatly increase production capacity, difficult to control product quality, high unit price, and difficult to form efficient market competitiveness. [0003] At present, the machining industry mainly takes automation and process central...
