According to shift fork special fixture described in the utility model, clamp body front end is provided with two circular holes, and is provided with location axle pin on two circular holes, is provided with two V-shaped grooves above clamp body, is rectangular channel bottom V-shaped groove, the gap be provided with between two V-shaped grooves; Clamp body rear end is a platform, and platform offers screwed hole and fore-set installing hole, and screwed hole is for installing double threaded screw, and fore-set installing hole is for installing fore-set; Offer six installing holes in clamp body bottom, six installing holes are distributed in clamp body low side both sides and every side distributes three, and installing hole is used for the screw of the connection of the concrete and lathe of mounting clamp.Gap between two V-shaped grooves is used for placed shifting fork leg, after placing shift fork leg, utilize the location axle pin be arranged on circular hole and big nut, and flat shim a and flat shim c coordinates the restriction shift fork leg left and right free degree; Utilize location axle pin middle circle cambered surface and shift fork inboard leg arc surface to fit simultaneously and limit shift fork Anterior-Posterior.
According to shift fork special fixture described in the utility model, location axle pin is cylinder pivot pin, mid portion axial plane and shift fork inboard leg cambered surface are fitted, and location axle pin two ends are provided with external screw thread, all big nut is installed at two ends, one end big nut joint jig body, is provided with flat shim a between other end big nut and clamp body.Utilize the big nut at location axle pin two ends to produce pretightning force thus limit the shift fork leg be placed in the middle of two V-shaped grooves.
The utility model has as follows a little:
Advantage one: the utility model structure is simple, reasonable in design, installs and easily manufactured, and the reliability of clamping shift fork is high, ensure that the working (machining) efficiency of shift fork crudy and raising shift fork.
Advantage two: the utility model offers two V-shaped grooves and two circular holes on clamp body, and V-shaped groove defines the placement location of shift fork, the location axle pin that two circular holes are installed controls shift fork four frees degree; And utilize the gap placed shifting fork leg between two V-shaped grooves; Although simplicity of design still meets the positioning requirements of shift fork.
Advantage three: this uses novel low cost of manufacture, dismounting and easy to maintenance; In the processing of shift fork, play key effect, be applicable to promoting the use of.
