Description
Technical field
The present invention relates to a kind of broaching machine main axle structure.
Background technology
In the prior art the broaching machine main shaft of processing inner hole of workpiece surface keyway drive broaching tool action by movable, it is necessary to
The rotating torques that servomotor is provided are converted to the front and rear thrust required for tool feeding；Broaching tool has fixed structure shape
Shape, is indexed on workpiece, it is impossible to process the special-shaped slots such as helicla flute, inner arc surface, cutter is carried out when interior feeding process is controlled not
Adapt to use demand.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of inside that can adapt to interior feeding tool use demand and moved
The broaching machine main axle structure of power supply.
The broaching machine main axle structure of the present invention, including main shaft, and main shaft are previously used for connecting the spindle end of cutter, and it is special
Levy and be：Main shaft is provided centrally with ball wire bar pair, and ball wire bar pair, which has to be driven by ball wire bar pair, to be moved forward and backward
Ball screw, ball wire bar pair rear end is connected with servomotor and can driven by servomotor movable；Ball screw
Pair is connected by actuating sleeve with servomotor；
Ball wire bar pair is arranged on inside main shaft by ball, is also set up between ball and main shaft inwall limited
Position support set；
Worm Wheel System pair is connected with below main shaft.
The broaching machine main axle structure of the present invention, the torque provided by ball screw adjutant servomotor is converted to tool feeding
Required front and rear thrust, can adapt to the internal motivation supply use demand of interior feeding tool, and the amount of feeding to cutter and
Direction of feed is controlled, and the rotation direction and rotational angle of ball screw are driven by ball screw actuating sleeve, is completed to knife
Direction of feed and the amount of feeding control of tool, simple in construction, convenient processing and manufacture.
