Problems solved by technology

[0003] The casting process of the fork involves grinding or milling the fork, and the fork needs to be positioned and clamped during the grinding or milling process. If the positioning and clamping device clamps the fork too much If the fork is too tight, the force on the fork will be too large, which will easily cause the fork to break or be unqualified during the grinding or milling process of the fork; if the positioning clamping device clamps the fork too loosely, the fork will Displacement is prone to occur during the milling process, resulting in unqualified workpiece processing and product scrapping

Abstract

The invention relates to the field of casting processing of shifting forks and discloses a positioning and clamping device for milling a plane on a shifting fork. The positioning and clamping device comprises a substrate, a clamping mechanism, a controller and a pressure sensor. The shifting fork is an A-shaped workpiece with a positioning hole formed at the pointed end and is arranged on a positioning pin through the positioning hole in a sleeving manner, and the two support legs of the A-shaped workpiece are erected on a support table. The clamping mechanism can prop and press the tops of the support legs in the vertical direction. The pressure sensor is arranged on the support table, and the controller is connected with the clamping mechanism and the pressure sensor. The pressure sensor can acquire a pressure signal born by the support legs and transmit the pressure signal to the controller, and the controller can control the clamping mechanism to start or stop according to the threshold value of the pressure signal. The positioning and clamping device is accurate in positioning and appropriate in clamping force, and therefore, guarantees that the shifting fork can neither displace when clamped nor be unqualified due to breakage caused by excessively high stress.

Description

technical field [0001] The invention relates to the field of cast fork processing, in particular to a positioning and clamping device for milling the plane of a shift fork. Background technique [0002] The fork is a part of the car gearbox. It is connected to the shift handle and is located at the lower end of the handle. It toggles the middle shift wheel to change the input / output speed ratio. The shift fork is mainly used for clutch shifting. It is connected with the shift handle and is located at the lower end of the handle. It moves the middle shift wheel to change the input / output speed ratio. Pull the two meshed gears apart, and then shift one of the gears that can slide on the shaft to the other gear to obtain another speed, that is, change the position of the slipping gear of the lathe to achieve speed change; or it can be used to control the clutch In the mechanism of engagement and disconnection, the horizontal or vertical feed can be controlled. [0003] The ca...
