Auxiliary positioning tool for milling double planes of reverse-gear shifting fork

Abstract

The invention discloses an auxiliary positioning tool for milling double planes of a reverse-gear shifting fork. The auxiliary positioning tool comprises a rack, a tool baseplate, supporting blocks, a left standing plate and a right standing plate; when a round hole of a revere-gear shifting fork sleeves a right sleeving cylinder and a right positioning block extends into the fork entry of the reverse-gear shifting fork, the ejector rod of a middle vertical cylinder upwardly extends out to exactly support the lower end surface of the reverse-gear shifting fork, and the ejector rod of a right vertical cylinder upwardly extends out to exactly support the waist of the reverse-gear shifting fork; after the reverse-gear shifting fork rotates by 180 degrees counterclockwise, the round hole of the reverse-gear shifting fork sleeves a left sleeve cylinder, a left positioning block extends into the fork entry of the reverse-gear shifting fork, and a left supporting block supports the lower part of the upper end surface of the reverse-gear shifting fork, an ejector rod of a left vertical cylinder upwardly extends out to exactly support the waist of the reverse-gear shifting fork. When used together with a vertical milling machine, the auxiliary positioning tool can complete processing of the upper plane of one workpiece and the lower plane of another workpiece at a time, clamping is convenient and quick, and the production efficiency and the machining precision are greatly improved.

Description

technical field [0001] The technical field of mechanical processing equipment of the present invention particularly relates to a positioning tool used for milling the upper and lower planes of a reverse gear shift fork. Background technique [0002] The reverse gear shift fork is one of the important parts of the automobile transmission. It is a cast-shaped part. It is necessary to use a milling machine to finish the upper and lower planes of the shift fork. The round shaft is clamped, and then processed by a horizontal milling machine. Since the upper and lower planes of the reverse gear fork are milled, two clamping and alignment are required, which is very troublesome, resulting in low machining accuracy and low production efficiency. Contents of the invention [0003] In view of the above technical problems, it is proposed to provide an auxiliary positioning tool for milling the double planes of the reverse gear shift fork. When the upper and lower planes of the shift...
