According to novel clamp described in the utility model, drill bushing is circular, and it is flange that centre is provided with through hole outer ring, and the sub-fraction thickness in flange is less than all the other thickness of flange; The part utilizing thickness different and drill bushing screw fit, well limit drill bushing, prevents drill bushing rotation in the horizontal direction, ensure that the smooth processing in shift fork hole.
According to novel clamp described in the utility model, clamping part comprises pressing plate, pressing plate platform and semicircle limited block; Pressing plate platform is connected with base by welding manner or bolt connecting mode, is connected, and arranges sphere armed nut at pressing plate top, utilize sphere armed nut and studs to rotate the pretightning force fixation clip produced above pressing plate platform by studs with pressing plate; Be provided with cylindroid helical-coil compression spring in the middle of pressing plate and pressing plate platform, add part in cylindroid helical-coil compression spring and be enclosed within studs.
According to novel clamp described in the utility model, semicircle limited block top is boss, and the boss left and right sides is the arc surface matched with shift fork leg.Utilize the arc surface of the cambered surface of shift fork leg and the boss left and right sides to fit and limit the rotation of shift fork.
The utility model tool has the following advantages:
Advantage one: the utility model is reasonable in design, structure is simple, easily manufactured, and assembling is simple, safeguards and is also easy to, while well ensureing machining hole quality, also improve operating efficiency.
A little two: the utility model, by designing cylindroid helical-coil compression spring cleverly in the middle of pressing plate and pressing plate platform, provides the strength of upwards pushing up for during pressing plate pressure shift fork cleverly.
A little three: the utility model adopts semicircle limited block and in boss both sides design cambered surface, recycling cambered surface and shift fork leg are fitted, and limit shift fork left rotation and right rotation cleverly.
