Because above-mentioned defect, the design people, actively in addition research and innovation, to founding a kind of processing unit (plant) of pointed tooth trepanning tool of new structure, make it have more value in industry.
Utility model content:
The purpose of this utility model is intended to solve prior art Problems existing, provides the processing unit (plant) of the pointed tooth trepanning tool that a kind of machining accuracy is high, efficiency is high.
The utility model relates to the processing unit (plant) of pointed tooth trepanning tool, comprises dividing head, and also comprise the taper shaft be inserted in described dividing head taper hole, one end of described taper shaft is provided with external splines; Described external splines is arranged with cam mould plate, described cam mould plate offers endoporus, described endoporus is provided with the internal spline coordinated with described external splines; Described cam mould plate has endoporus one end and is connected with cam motherboard by pattern spring, and the other end is fixedly installed workpiece assembling seat; Described cam motherboard and cam mould plate are respectively equipped with the spur tooth cooperatively interacted; Described cam motherboard is fixedly mounted on base, and described workpiece assembling seat is provided with trepanning tool.
Preferred as such scheme, is provided with through hole in the middle part of described base, and described taper shaft is through described through hole.
Preferred as such scheme, described cam motherboard does not contact with taper shaft.
Preferred as such scheme, the center of described trepanning tool, workpiece assembling seat, cam mould plate, cam motherboard, base and taper shaft is all by the axle center of dividing head.
Preferred as such scheme, described workpiece assembling seat is arranged on cam mould plate end face by trip bolt.
Preferred as such scheme, described trepanning tool is arranged on workpiece assembling seat by screw.
By such scheme, the utility model at least has the following advantages: the utility model is by sheathed cam mould plate on the taper shaft at one end with external splines, cam mould flat spring connects cam motherboard, cam mould plate can be rotated with taper shaft and is close to cam motherboard by spring to carry out axis movable, by the effect of pointed tooth cooperatively interacted, cam mould strip is moved trepanning tool and is moved formation pointed tooth relief angle track, thus processes pointed tooth relief angle; The utility model is for trepanning tool processing key, utilize plane cam, pattern process principle, without the need on dividing head change gear hand walk differential processing spiral relief angle, for trepanning tool pointed tooth tool clearance processing reformed new technology, new tool, efficiency and quality are obtained for raising.
Above-mentioned explanation is only the general introduction of technical solutions of the utility model, in order to better understand technological means of the present utility model, and can be implemented according to the content of description, coordinates accompanying drawing to be described in detail as follows below with preferred embodiment of the present utility model.
Accompanying drawing illustrates:
The following drawings is only intended to schematically illustrate the utility model and explain, does not limit scope of the present utility model.Wherein:
Fig. 1 is the side structure schematic diagram of the processing unit (plant) of the utility model pointed tooth trepanning tool;
Fig. 2 is the profile of A-A line in Fig. 1;
Fig. 3 is the side structure schematic diagram of trepanning tool in the utility model;
Fig. 4 is the right view of Fig. 3.
Detailed description of the invention:
Below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is described in further detail.Following examples for illustration of the utility model, but are not used for limiting scope of the present utility model.
See Fig. 1, Fig. 2, the processing unit (plant) of pointed tooth trepanning tool described in the utility model, comprises dividing head (not shown), also comprises the taper shaft 1 be inserted in described dividing head taper hole, and one end of described taper shaft 1 is provided with external splines 11; Described external splines 11 is arranged with cam mould plate 2, described cam mould plate 2 offers endoporus (not shown), described endoporus is provided with the internal spline (not shown) coordinated with described external splines 11; Described cam mould plate 2 has endoporus one end and is connected with cam motherboard 4 by pattern spring 3, and the other end is fixedly installed workpiece assembling seat 5; Described cam motherboard 4 does not contact with taper shaft 1, and described workpiece assembling seat 5 is arranged on cam mould plate 2 end face by trip bolt 6; Described cam motherboard 4 and cam mould plate 2 are respectively equipped with the spur tooth 7 cooperatively interacted; Described cam motherboard 4 is fixedly mounted on base 8, is provided with through hole 81 in the middle part of described base 8, and described taper shaft 1 is through described through hole 81, and described workpiece assembling seat 5 screwing 51 is provided with trepanning tool 9; The center of described trepanning tool 9, workpiece assembling seat 5, cam mould plate 2, cam motherboard 4, base 8 and taper shaft 1 is all by the axle center of dividing head.
