Background

In the process of machining the shifting fork, the drilling clamp plays an important role, Chinese invention patent CN 107344298A discloses a shifting fork drilling clamp which comprises a base, wherein two side edges of the upper surface of the base are respectively and fixedly provided with a stand column and a clamping cylinder, a vertical lifting screw rod is arranged in the stand column, a guide sleeve is arranged on the lifting screw rod through threaded connection, a through hole is formed in the base corresponding to the position under the guide sleeve, a cushion cover is nested on the inner side wall of the through hole, a top head is fixedly arranged at the position of the end head of a piston of the clamping cylinder, a V-shaped block is fixedly arranged on one side, close to the stand column, of the upper surface of the base, and the opening of the V-shaped block points. This kind of anchor clamps for shifting fork spare drilling are through placing the shifting fork work piece on filling up the platform, and the cooperation is filled up and is kept each part of work piece and keep the level to adopt the uide bushing to carry out drilling guiding orientation, compress tightly fixedly the drilling position simultaneously, the phenomenon of forging a knife can not appear, improves drilling accuracy, still has following defect: during drilling operation, shifting fork atress easily takes place the displacement, and prior art generally only realizes compressing tightly fixed of shifting fork, can only realize the fixed of two directions, and the precision still is difficult to guarantee during drilling.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that a shift fork boring grab is provided to solve the defect that exists among the prior art.

The utility model provides an above-mentioned technical problem's technical scheme as follows:

a shifting fork drilling clamp comprises a base and a supporting column located on the base, wherein a transverse support is fixed above the supporting column through a first positioning pin and a hexagon socket head cap screw in a matched mode, a drilling template is arranged on the transverse support, a drilling sleeve is arranged in the center of the drilling template, a fixed V-shaped block is fixed on the supporting column through a second positioning pin and a straight-line groove flat-head screw, a pressing block is arranged on one side, opposite to the fixed V-shaped block, of the pressing block and a handle are connected through a screw rod, the handle is rotated to move the screw rod so as to drive the pressing block to move forward or backward, and the; a stop pin is arranged on the base in the direction vertical to the middle point of the connecting line of the fixed V-shaped block and the pressing block;

furthermore, a lining with a buffering function is arranged between the drill plate and the drill bushing;

further, the screw is matched with the stud through a nut and fixed on the support; a liftable supporting plate is arranged below the hole drilled in the base and used for supporting a shifting fork;

the utility model has the advantages that: the multi-degree-of-freedom fixing of the shifting fork is realized through the matching of the fixed V-shaped block, the screw rod and the stop pin, the processing precision can be improved, the screw rod is controlled through the handle to facilitate the mounting and dismounting of the shifting fork, meanwhile, the lifting support plate on the base can realize the flexible adjustment of the shifting forks with different sizes, and the application range is wide.
