Summary of the invention
The machining tool that the object of the present invention is to provide multidimensional to rotate utilizes this lathe can carry out the processing of the high-grade globoid cam of different size.
To achieve these goals, the present invention adopts following technological means to realize.
A kind of globoid cam machining tool is provided with frame, and the extension of frame is the main spindle box base, on the main spindle box base, is provided with the main spindle box of removable adjusting; Main spindle box is provided with the cutter spindle of mounting cutter; Frame is provided with the workpiece turntable that is horizontally rotated by driven by motor, and this workpiece turntable is provided with the work support of clamping and rotatable workpiece, and the plane of rotation of workpiece is a vertical plane; The workpiece turntable is provided with two closed slides, and work support can move along this guide rail; Work support is provided with the thimble support, through the fixing part to be processed of thimble support.
Be respectively equipped with retaining mechanism at work support and thimble support;
Described work support is provided with the central rotating shaft by the driven by motor rotation;
Be provided with thimble in the described thimble support, thimble and expansion shaft and can move forward and backward on same axis; The workpiece that will be fixed on the expansion shaft through mobile thimble withstands.
Said work support and thimble support are installed on the workpiece turntable through support guide respectively, and work support and thimble support can be moved along guide rail synchronously, and are provided with retaining mechanism work stage is fixed.
Aforesaid work support drives the workpiece that is enclosed within on the central rotating shaft through central rotating shaft and makes vertical rotation, and the workpiece turntable drives work support and horizontally rotates, and the rotation of central rotating shaft and workpiece turntable is undertaken by certain functional relation through motor.This central rotating shaft is a keyway formula expansion shaft.
Aforesaid locked mechanism is the hand screw.
Globoid cam machining tool of the present invention compared with prior art, has following beneficial effect and advantage:
Adopt the design of workpiece turntable and central rotating shaft, workpiece can be rotated with vertical both direction in level simultaneously, and two rotations make workpiece move by certain functional relation by Controlled by Programmable Controller, thereby process high-grade globoid cam.And make the centre of gyration distance of workpiece and workpiece turntable adjustable through slide rail, thereby process the globoid cam of different size.
