Device for removing burr from inner pin hole of gear shifting oscillating bar

Abstract

The invention discloses a device for removing burr from an inner pin hole of a gear shifting oscillating bar. The device for removing the burr from the inner pin hole of the gear shifting oscillating bar comprises a pedestal, a support post, a drive motor, an engaging and retracting drive cylinder, a hard alloy rotary file and a sliding support plate, an automobile oscillating bar sleeve post and an automobile oscillating bar rotation resisting block are firmly arranged above the sliding support plate, a manual oscillating bar is hinged to the middle of the front side wall of the sliding support plate, a connecting bar which extends horizontally is arranged at each of the left and right sides of the sliding support plate, a reset spring sleeves each connecting bar, a support block for supporting the connecting bar is arranged at the outer side of each connecting bar, a left bearing and a right bearing for guiding the horizontal move of the sliding support plate are arranged at each of the front and rear sides of the sliding support plate at intervals, and a limit plate for limiting the horizontal move of the sliding support plate is arranged at each of the left and right sides of the neck of the sliding support plate. The device for removing the burr from the inner pin hole of the gear shifting oscillating bar is novel and smart in design, convenient to operate, high in automatic degree and broad in popularization, and the production efficiency and product consistency are obviously improved.

Description

technical field [0001] The technical field of mechanical processing equipment of the present invention particularly relates to a device for removing burrs in inner pin holes on shift levers of automobile transmissions. 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, and the body A is provided with a shift shaft installation hole D and a positioning pin hole E (also called an inner pin hole) , 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 th...

[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
