Abstract

The invention discloses a press-fitting positioning device for gear selecting and shifting waveform block of manual transmission. The press-fitting positioning device comprises a base, a U-shaped positioning block and a guide rod, the U-shaped positioning block and the guide rod are installed on the base, a positioning hole is formed in the base, the positioning hole is used for fixing the end part of a gear selecting and shifting shaft, the U-shaped positioning block matches with a shifting block on the gear selecting and shifting shaft and used for limiting the shifting block to rotate around the axis of the gear selecting and shifting shaft, and a cylindrical surface is arranged on the guide rod, matches with the waveform area of the waveform block and is used for carrying out radial positioning and axial guiding on the waveform block. Therefore, according to the press-fitting positioning device for the gear selecting and shifting waveform block of the manual transmission, axial direction limiting is conducted through the waveform block working area in the press-fitting process, the problem that the coaxiality of the gear selecting and shifting shaft and the pressing head is poor can be solved, axial whole-process positioning can be further conducted on the waveform block, the coaxiality of the gear selecting and shifting rod and the pressing head in the pressing process of the waveform block can be reliably ensured, and the pressing precision of the waveform block is ensured.

Description

Technical field[0001]The present invention relates to the field of automotive assemblies, and more particularly to a manual transmission to select a shifting waveform block pressing positioning device.Background technique[0002]The manual transmission is one of the automotive transmission, and the selection of the modified waveform block is an important component in the manual transmission.[0003]Such asPicture 1-1 withFigure 1-2 As shown, the selection of the modulation wave block 2 and the gripper 3 simultaneously fix the sleeve on the selected stop shaft 1 to achieve the operation of the selected gear, the waveform region 2-1 of the shifting wave block 2 is generally located. The two sides opposite the baffle shaft 1 are selected, and there is a V-recess on the right side of the waveguide block 2. During the specific selection process, the working position of the header 3 relates to the axial displacement of the shifting shaft 1, and the other aspect relates to the rotation of the ...
