The utility model solves the technical scheme that its technical problem adopted:
A kind of globoid cam numerical control milling special plane; Comprise lathe bed, said lathe bed upper edge directions X is provided with crossbeam, and the front end of said crossbeam is provided with X to slide plate; Said X is relatively set with workpiece spindle box and tailstock to slide plate upper edge directions X; Be provided with work spindle in the said workpiece spindle box, be positioned on the said lathe bed X to a side of slide plate along Y to being provided with Y to slide plate, said Y is provided with a panoramic table to slide plate; Said panoramic table is provided with tool head, is provided with cutter spindle in the said tool head.
The utility model also can be done following improvement:
As the improvement of technique scheme, said crossbeam is across being arranged on the lathe bed, and said Y can be along Y to sliding into the crossbeam front and back to slide plate.
As the further improvement of technique scheme, said tool head is slidingly arranged on the panoramic table, and axle is mobile along a straight line on panoramic table for it.
Further improvement as technique scheme also comprises a dresser.
As the further improvement of technique scheme, said dresser is mounted on the workpiece spindle box.
As the further improvement of technique scheme, said tool head is slidingly connected on panoramic table through the panoramic table slide block that is fixed on panoramic table guide rail on the said panoramic table, be slidingly matched with the panoramic table guide rail.
Compared with prior art, the beneficial effect of the utility model is: the work spindle of the utility model is in order to install workpiece (globoid cam), and its cutter spindle is in order to install emery wheel or milling cutter.Globoid cam is being added man-hour, and it is motionless earlier X to be moved to suitable fixed-site to slide plate and Y to slide plate, falls on the pivot axis of panoramic table with the cambered surface center of circle of assurance workpiece (globoid cam).Because the emery wheel or the milling cutter that are installed on the cutter spindle can be when the axis of cutter spindle be done rotation, again can be along with the revolution of panoramic table the central axis of wraparound turntable swing back and forth.Like this, in the whole machining process process, emery wheel or milling cutter are equivalent to the roller of globoid cam clutch plate.Simultaneously, in this process, workpiece (globoid cam) only needs rotatablely moving of work spindle and panoramic table then by the work spindle driven rotary in the whole machining process process, promptly only needs two-axle interlocking just can realize the continuous milling processing of globoid cam internal channel.
Description of drawings
In order to be illustrated more clearly in the technical scheme among the utility model embodiment, the accompanying drawing of required use is done simple declaration in will describing embodiment below:
Fig. 1 is the structural representation of an embodiment of the utility model globoid cam numerical control milling special plane;
Fig. 2 is the front elevational schematic of embodiment among Fig. 1;
Fig. 3 is the schematic top plan view of embodiment among Fig. 1.
The specific embodiment
Below will combine embodiment and accompanying drawing that the technique effect of design, concrete structure and the generation of the utility model is carried out clear, intactly description, with purpose, characteristic and the effect of understanding the utility model fully.
Require emphasis, position relations such as alleged upper and lower, forward and backward a, left side and the right side all are based on the accompanying drawing of the utility model in the utility model, are not to be understood that to be the restriction to the utility model.
With reference to Fig. 1, Fig. 2 and Fig. 3, the structural representation of all angles of an embodiment of the globoid cam numerical control milling special plane of the utility model, it comprises lathe bed 1, and said lathe bed 1 upper edge directions X is provided with crossbeam 2, and the front end of said crossbeam 2 is provided with X to slide plate 3.In the present embodiment, said X is slidingly connected on crossbeam 2 to slide block 22 to the X that guide rail 21 is slidingly matched to guide rail 21, with X through the X that is fixed on the crossbeam 2 to slide plate 3.Said X is relatively set with workpiece spindle box 4 and tailstock 5 to slide plate 3 upper edge directions Xs; Be provided with work spindle 41 in the said workpiece spindle box 4; Be positioned on the said lathe bed 1 X to a side of slide plate 3 along Y to being provided with Y to slide plate 6, said Y to slide plate 6 through the Y on the fixing lathe bed 1 to guide rail, be slidingly connected on lathe bed 1 to slide block to the Y that guide rail is slidingly matched with Y.Said Y is provided with a panoramic table 7 to slide plate 6, and said panoramic table 7 is provided with tool head 8, is provided with cutter spindle 81 in the said tool head 8.Through above-mentioned configuration, X to slide plate 3 along X to move can adjust workpiece X to the position; The rotation of cutter spindle 41 can drive workpiece (globoid cam) rotation; Y to slide plate 6 along Y to move and can adjust the centre-to-centre spacing of panoramic table 7 and cutter spindle 41; The central axis that the revolution of panoramic table 7 can drive cutter spindle 81 wraparound turntables 7 swings back and forth; The rotation of work spindle 81 can drive emery wheel or milling cutter rotation.
