Description

Device convenient to integral key shaft secondary machining hole and groove Technical Field The utility model relates to the technical field of secondary machining of spline shafts, in particular to a device for facilitating secondary machining of holes and grooves of spline shafts. Background The spline shaft is mechanically driven, and has the same function as that of flat key, semi-circular key and inclined key, and is used to transmit mechanical torque. While rotating, some may also slide longitudinally on the shaft, such as a gearbox shift gear or the like. When the spline shaft is subjected to secondary machining of holes and grooves, in order to ensure the machining precision, the spline shaft needs to be firmly clamped, the holes and the grooves are ensured to be stable enough, the machining effect is ensured, the clamping tool used at present is inflexible to use, the position of the end face of the spline shaft, which is easy to block, of the groove on the outer surface of the spline shaft is clamped, and the machining is prevented. Disclosure of utility model The present utility model aims to solve one of the technical problems existing in the prior art or related technologies. The technical scheme adopted by the utility model is as follows: The utility model provides a device convenient to integral key shaft secondary operation hole and groove, includes supporting mechanism and fastening mechanism, supporting mechanism include the integral key shaft, the activity cup joint in two supporting seats at integral key shaft both ends, fastening mechanism including slip run through in a plurality of threaded rods of supporting seat, with two nuts of threaded rod spin joint, with guide shell that threaded rod one end is connected, slidable mounting in inside the slider of guide shell, spin joint in a plurality of bolts of guide shell one side, with the fixture block that the slider is connected, fixture block and integral key shaft activity joint. Through adopting above-mentioned technical scheme, along the position of supporting seat removal threaded rod, the guide shell that is connected with the threaded rod on the integral key shaft is adjusted, makes it avoid processing hole and groove, then screws the nut to remove the slider along the guide shell, make the notch that has seted up on fixture block and the integral key shaft align, then screw the bolt for fixed slider is whole, then the supporting seat cover is in the integral key shaft outside, a plurality of fixture block cooperation, firm locking integral key shaft avoids the integral key shaft to displace in secondary processing, makes the processing operation more smooth.
