A tool for deburring the inner end of the positioning pin hole of the shift lever of the automobile transmission

Abstract

The invention discloses a tool for deburring the inner end of a positioning pin hole of a gearshift swing rod of an automobile transmission, which includes a workbench, a sliding support plate, and an automobile swing rod set cylinder and an automobile swing rod anti-rotation block are fixed above the sliding support plate. A manual swing rod is hinged at the middle position of the front side wall of the sliding pallet, and a connecting rod extending left and right is respectively arranged on the left and right sides of the sliding pallet, and a return spring is set on the connecting rod, and the outside of each connecting rod is provided with a There are support blocks for supporting the connecting rods. Two bearings arranged at intervals on the left and right are arranged on the front and rear sides of the sliding pallet to guide the left and right movement of the sliding pallet. There is a limit position on the left and right sides of the neck of the sliding pallet The plate is the left and right movement limit of the sliding pallet. The concept is novel, the design is ingenious, the operation is convenient, the degree of automation is high, the production efficiency and product consistency are significantly improved, and it has extensive promotion value.

Description

technical field [0001] The technical field of mechanical processing equipment of the present invention particularly relates to a tool for removing burrs at the inner end of a positioning pin hole on a shift lever of an automobile transmission. Background technique [0002] The shift lever is one of the important parts of the automobile transmission, combined with figure 1 , figure 2 As shown, the shift lever includes a body A. One end of the body 1 is a ball head B, and the other end is a steel ball groove C. A large shift shaft installation hole D and a small positioning pin hole E are opened on the body A. The positioning pin hole E is perpendicular to the shift shaft mounting hole D. [0003] The positioning pin hole E runs through the entire body A. After the positioning pin hole E is machined, burrs will be left on the two inner ends, which will affect the installation of the shift shaft. The conventional method of deburring is to manually use a file and extend the f...

[0003] The positioning pin hole E runs through the entire body A. After the positioning pin hole E is machined, burrs will be left on the two inner ends, which will affect the installation of the shift shaft. The conventional method of deburring is to manually use a file and extend the file into the shift shaft. Deburring in mounting hole D

This deburring method is inefficient and has poor product consistency
