Burr removing tool for inner end of positioning pin hole of gear shifting swing rod of automobile transmission

Abstract

The invention discloses a burr removing tool for an inner end of a positioning pin hole of a gear shifting swing rod of an automobile transmission. The burr removing tool comprises a working table and a sliding supporting plate; an automobile swing rod sleeve cylinder and automobile swing rod anti-rotating blocks are fixedly arranged above the sliding supporting plate; a manual swing rod is hinged to the middle position of the front side wall of the sliding supporting plate; the left side and the right side of the sliding supporting plate are each provided with a connecting rod which extends left and right; each connecting rod is sleeved with a return spring. The outer side of each connecting rod is provided with a supporting block for supporting the corresponding connecting rod; the front side and the rear side of the sliding supporting plate are each provided with two bearings; the bearings are arranged at intervals in a left and right manner to guide left and right moving of the sliding supporting plate; and the left side and the right side of the neck of the sliding supporting plate are each provided with a limiting plate for limiting left and right moving of the sliding supporting plate. The burr removing tool is novel in conception, ingenious in design, convenient to operate and high in automation degree; the production efficiency and product consistency are remarkably improved; and the burr removing tool has the wide popularization 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
