Description
Technical field
The present invention relates to milling machine tooling field, and in particular to a kind of power transmission shaft keyseat frock.
Background technology
In power drive system, power transmission shaft plays connection actuating unit and fitness machine as a power transmission component
The effect of structure, when being connected installation with other parts, it is attached frequently with key block, because the connector on power transmission shaft is usual
More than one, thus need to mill out multiple different keyways, in addition, usual not along multiple keyways of drive shaft axis distribution
In same direction, relatively conventional is：Two keyways open up direction and are mutually perpendicular to, and this key grooves conventional machining mode is：First
A certain keyway is processed, then the machining angle of power transmission shaft is adjusted by the dividing head on milling machine, and then milling is carried out to another keyway
Processing is cut, this processing mode significantly increases the occupation rate of lathe, less efficient, and operating personnel need higher clamping
Technical ability, otherwise it cannot be guaranteed that the perpendicularity of keyway, also or using four-shaft numerically controlled milling machine is processed, still, this equipment valency
Lattice are expensive, are unnecessary production burdens for the processing enterprise of Ordinary Work demand.
The content of the invention
It is an object of the invention to provide a kind of power transmission shaft keyseat frock, to solve the axle referred in above-mentioned background technology
On class part orthogonal keyway in milling process caused clamping inconvenience, perpendicularity difference, efficiency is low, cost of labor is high etc.
Problem.
To achieve the above object, the present invention provides following technical scheme：A kind of power transmission shaft keyseat frock, including chuck
Body, drive mechanism and claw, the clamping part of the claw is stepped, and it is V-arrangement to form confined planes and clamping face, the clamping face
Structure, surface are provided with wear-resistant gasket, and radial direction of the clamping face along chuck body is further opened with and keyway phase on workpiece
The positioning spline of cooperation, the claw side are provided with inductor, and corresponding to inductor on the chuck body is provided with limited block.
Drive and make claw close to each other, power transmission shaft is placed in inside the region that claw clamping face formed, power transmission shaft one
End is fixed on confined planes, and workpiece is positioned in claw by key block, drives claw again, clamps power transmission shaft, you can is carried out
The Milling Process of another keyway；
In the moving process close to each other of claw, due to manually-operated uncertainty, in order to prevent maloperation from causing
Claw clamping face produces mutually extruding and influences machining accuracy, the inductor moment set by claw side monitor inductor with
The distance of limited block, when actual range is less than setting value, inductor will alarm, and to remind processing staff, claw has arrived
Extreme position, otherwise, the clamping face of claw will be extruded mutually, destroy the clamping face precision of claw.
Further：The claw upper surface opens up an oil filler point.
It can be needed by corrective maintenance, lubricating oil is injected between claw and drive mechanism, improve the service life of frock.
Further：The drive mechanism includes the dish-shaped bevel gear and cone pinion to cooperate, the dish-shaped umbrella tooth
Wheel surface is provided with screw thread, and the claw spigot surface is provided with the screw thread being engaged with dish-shaped umbrella tooth wheel surface, the chuck body side surface
Four square holes are opened up, the small bevel gear wheel shaft connects a rotational handle through four square holes.
As preferred：The claw sets 3-4.
As preferred：The claw is made using 45# steel.
Compared with prior art, the beneficial effects of the invention are as follows：
（1）The tool structure is reasonable, and use and maintenance is convenient, and volume is light and handy, suitable for the transformation of plain-milling machine；
（2）The self-centering installation way of pawl card, improve the efficiency of clamping；
（3）In a manner of the keyway that completed is positioned, the perpendicularity between another keyway and this keyway can be improved, is reduced
Centering difficulty of the processing staff to workpiece.
