The content of the invention
In view of this, it is an object of the invention to provide a kind of splined shaft groove milling clamping and positioning device, Set and Positioning can be carried out to the splined shaft for being provided with spline tooth, to meet the Milling Process requirement of groove.
To reach above-mentioned purpose, the present invention provides following technical scheme：
A kind of splined shaft groove milling clamping and positioning device, including base, the upper surface of the base is provided with clamping slot, the bottom of the clamping slot is provided with locating piece, the locating piece is provided with spacing with least two spline tooths with merging positioning tooth that the teeth groove of further groove milling will be needed to be alignd with milling cutter, and the clamping slot the hold-down mechanism being respectively provided on two sides with for spline shaft body to be pressed abd fixed on the locating piece and the engagement detent mechanism for being engaged with spline tooth；The engagement detent mechanism includes gear block and the engagement cylinder for driving gear block to be moved along the radial direction of spline shaft body, and the gear block is provided with the engaging tooth engaged with spline tooth.
Further, it is two that the positioning tooth is symmetrical arranged.
Further, the hold-down mechanism include rotatable engagement be arranged on the base on briquetting and for driving the briquetting to rotate and compressing the compression actuating unit of spline shaft body, the rotation axis of the briquetting is parallel with the length bearing of trend of the clamping slot.
Further, the base is provided with the gathering sill for the gear block mobile guide.
The beneficial effects of the present invention are：
Splined shaft groove milling clamping and positioning device of the invention, by setting base, and locating piece is set in clamping slot, when using, main shaft is placed in clamping slot, and positioning tooth and spline tooth are coordinated into positioning, gear block is driven to be engaged with spline tooth, then main shaft is fixed using hold-down mechanism, in this way, can will easily need the teeth groove of further groove milling to be alignd with milling cutter, place splined shaft radial rotary and bounce, to meet the Milling Process requirement of groove, with simple structure, the advantage of easy to operate and clamping stabilization.
Brief description of the drawings
In order that the purpose of the present invention, technical scheme and beneficial effect are clearer, the present invention provides drawings described below and illustrates：
Fig. 1 is a kind of longitudinal section view of existing splined shaft；
Fig. 2 is the structural representation of splined shaft groove milling clamping and positioning device embodiment of the present invention.
Specific embodiment
The invention will be further described with specific embodiment below in conjunction with the accompanying drawings, so that those skilled in the art can be better understood from the present invention and can be practiced, but illustrated embodiment is not as a limitation of the invention.
As shown in Fig. 2 being the structural representation of splined shaft groove milling clamping and positioning device embodiment of the present invention.The splined shaft groove milling clamping and positioning device of the present embodiment, including base 4, the upper surface of the base 4 is provided with clamping slot 5, the bottom of the clamping slot 5 is provided with locating piece 6, the locating piece 6 is provided with spacing with least two spline tooths 2 with merging positioning tooth 7 that the teeth groove of further groove milling will be needed to be alignd with milling cutter 9, and the clamping slot 5 the hold-down mechanism being respectively provided on two sides with for spline shaft body 1 to be pressed abd fixed on the locating piece 6 and the engagement detent mechanism for being engaged with spline tooth 2.The engagement detent mechanism of the present embodiment includes gear block 10 and the engagement cylinder 11 for driving gear block 10 to be moved along the radial direction of spline shaft body 1, and the gear block 10 is provided with the engaging tooth engaged with spline tooth 2.Preferably, the base 1 is provided with the gathering sill for the mobile guide of the gear block 10.
Further, it is two that the positioning tooth 7 of the present embodiment is symmetrical arranged, two positioning tooths 7 respectively with the spacing cooperation of two spline tooths 2, can effectively prevent spline shaft body 1 from rotating.
