Rapid clamping device for shifting fork of transmission

Abstract

The invention discloses a rapid clamping device for a shifting fork of a transmission. A front supporting base and a rear supporting base are installed on a base board. The front end of a horizontal positioning shaft is installed on the front supporting base, the rear end of the horizontal positioning shaft is installed on the rear supporting base, and a step face is arranged in the middle of the horizontal positioning shaft. The rear supporting base is further horizontally provided with a positioning plate mandrel; the front end of the positioning plate mandrel is fixedly sleeved with a positioning plate; the positioning plate is a conical plate with the small front portion and the large rear portion; screws penetrate through the second supporting base from back to front to be fixed to the positioning plate together, the screws are sleeved with springs, and accordingly floating installation of the positioning plate is achieved. An oil hydraulic cylinder is installed on the front supporting base and acts on the front end of the horizontal positioning shaft so as to push the horizontal positioning shaft to move forwards and compress a workpiece. The horizontal positioning shaft is supported and compressed bilaterally and combined with the conical positioning plate installed in a floating mode, so that product stress is good, and the percent of pass is above 98%; the oil hydraulic cylinder is used for compression, the speed is high, operation is easy and fast, and the occupied space is small.

Description

technical field [0001] The invention relates to a processing and clamping device for a shift fork of a transmission, in particular to a quick clamping device for a shift fork of a transmission. Background technique [0002] Such as Image 6 As shown, the shift fork shaft of the transmission is usually molded by casting, including the semicircular shift fork body A, the installation shaft hole B and the fork port C, the three are connected as one, and the installation shaft hole B and the fork port C are set outside of the fork body. [0003] At present, the end face D of the fork opening C of the shift fork shaft of the transmission is milled on the vertical machining center, and the clamping device is manually pressed, which is slow and difficult to operate; at the same time, the aperture of the workpiece is long, and the positioning mandrel is too long to press. The tight force is not good, the product moves during processing, and the size processing is unstable, so that ...

Problems solved by technology

[0003] At present, the end face D of the fork opening C of the shift fork shaft of the transmission is milled on the vertical machining center, and the clamping device is manually pressed, which is slow and difficult to operate; at the same time, the aperture of the workpiece is long, and the positioning mandrel is too long to press. The stress after tightening is not good, the product moves during processing, and the size processing is unstable, so that the qualified rate of the product can only reach 85%.
