Machine for removing burrs in through hole of gear-shifting oscillating bar of transmission

Abstract

The invention discloses a machine for removing burrs in a through hole of a gear-shifting oscillating bar of a transmission. The machine comprises a base, a supporting column, a driving motor, a feeding and retracting driving cylinder, a rotating hard alloy file and a sliding supporting plate; an automobile oscillating bar sleeve column and an automobile oscillating bar anti-rotation block are fixedly arranged above the sliding supporting plate; a hand-operated oscillating bar is hinged to the middle position of the front sidewall of the sliding supporting plate; two bearings arranged left and right at an interval are arranged on the front and rear sides of the sliding supporting plate to guide the left-and-right movement of the sliding supporting plate; limiting plates are arranged on the left and right sides of the neck of the sliding supporting plate to limit the left-and-right movement of the sliding supporting plate. The machine for removing burrs in the through hole of the gear-shifting oscillating bar of the transmission is novel in design, ingenious in design, convenient to operate, and high in degree of automation, and worthy of wide popularization; besides, the production efficiency and the product consistency are remarkably 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 a through 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 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
