Description
Technical field
This utility model belongs to mechanical frock clamp art, is specifically related to a kind of gear shaft groove milling positioning and clamping device.
Background technology
As it is shown in figure 1, be the longitudinal section view of existing a kind of gear shaft.This gear shaft includes gear shaft body 1, and the periphery wall of gear shaft body 1 is toothed around 2, and teeth groove place between two gear teeth 2 is further provided with the groove 3 widened wherein.The gear teeth 2 can be involute gear tooth, naturally it is also possible to for the gear teeth of other structures.In prior art, in order to meet the status requirement between groove 3 and the gear teeth 2, it is generally required to the present processing gear teeth 2 on gear shaft body 1, then working groove between two gear teeth 2 wherein.Due to the construction features of this gear shaft, prior art is not specifically designed for its frock clamp when working groove 3.
Summary of the invention
In view of this, the purpose of this utility model is in that to provide a kind of gear shaft groove milling positioning and clamping device, it is possible to the gear shaft being toothed around is carried out Set and Positioning, to meet the Milling Process requirement of groove.
For reaching above-mentioned purpose, this utility model provides following technical scheme:
A kind of gear shaft groove milling positioning and clamping device, including base, the upper surface of described base is provided with the clamping groove for holding gears axle body, described clamping groove be respectively provided on two sides with the hold-down mechanism for gear shaft body is fixed and be used for gear teeth meshing positioning tooth wheel shaft body engage detent mechanism；Described engagement detent mechanism includes gear block and the engagement cylinder for driving gear block to move along the radial direction of gear shaft body, and described gear block is provided with the engaging tooth with gear teeth meshing.
Further, described hold-down mechanism includes rotatable engagement and is arranged on the briquetting on described base and for driving described briquetting to rotate and compressing the compression actuating unit of gear shaft body, and the rotation axis of described briquetting is parallel with the length bearing of trend of described clamping groove.
Further, described base is provided with the gathering sill for described gear block mobile guide.
The beneficial effects of the utility model are in that:
Gear shaft groove milling positioning and clamping device of the present utility model, by being respectively provided with hold-down mechanism and engagement detent mechanism in the both sides of clamping groove, utilize the meshing relation between gear block and the gear teeth, can positioning tooth wheel shaft body, and prevent gear shaft body from rotating along its axis；Hold-down mechanism is utilized to be pressed abd fixed on clamping groove or gear block by gear shaft body, it is possible to prevent gear shaft body circular runout；So, the Set and Positioning requirement to gear shaft can be realized, to meet the Milling Process requirement of groove, and there is simple in construction, the advantage that easy to operate and clamping consolidates.
Accompanying drawing explanation
In order to make the purpose of this utility model, technical scheme and beneficial effect clearly, this utility model provides drawings described below to illustrate:
Fig. 1 is the longitudinal section view of existing a kind of gear shaft；
Fig. 2 is the structural representation of this utility model gear shaft groove milling positioning and clamping device embodiment.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, so that those skilled in the art can be better understood from this utility model and can be practiced, but illustrated embodiment is not as to restriction of the present utility model.
As in figure 2 it is shown, be the structural representation of this utility model gear shaft groove milling positioning and clamping device embodiment.The gear shaft groove milling positioning and clamping device of the present embodiment, including base 4, the upper surface of described base 4 is provided with the clamping groove 5 for holding gears axle body 1, being respectively provided on two sides with the hold-down mechanism for being fixed by gear shaft body 1 and be used for engaging with the gear teeth 2 and the engagement detent mechanism of positioning tooth wheel shaft body 1 of described clamping groove 5.The described engagement detent mechanism of the present embodiment includes gear block 6 and the engagement cylinder 7 for driving gear block 6 to move along the radial direction of gear shaft body 1, and described gear block 6 is provided with the engaging tooth engaged with the gear teeth 2.
Further, the hold-down mechanism of the present embodiment includes rotatable engagement and is arranged on the briquetting 8 on described base 4 and for driving described briquetting 8 to rotate and compressing the compression actuating unit of gear shaft body 1, and the rotation axis of described briquetting 8 is parallel with the length bearing of trend of described clamping groove 5.Compressing actuating unit can adopt existing various structures mode to realize, and as adopted air cylinder driven briquetting 8 to rotate, its principle is suitable, is not repeated.By being respectively provided with briquetting 8 in the both sides of clamping groove 5, it is possible to avoid gear shaft body 1 that circular runout occurs in Xiyanping injection process.
Further, described base 4 is provided with the gathering sill for described gear block 6 mobile guide, guiding gear block 6 slide meanwhile, it is capable to gear block 6 is carried out spacing, accurate to guarantee that its position of engagement with gear shaft body 1 is stablized.
The gear shaft groove milling positioning and clamping device of the present embodiment, by being respectively provided with hold-down mechanism and engagement detent mechanism in the both sides of clamping groove, utilizes the meshing relation between gear block and the gear teeth, can positioning tooth wheel shaft body, and prevent gear shaft body from rotating along its axis；Hold-down mechanism is utilized to be pressed abd fixed on clamping groove or gear block by gear shaft body, it is possible to prevent gear shaft body circular runout；So, the Set and Positioning requirement to gear shaft can be realized, to meet the Milling Process requirement of groove, and there is simple in construction, the advantage that easy to operate and clamping consolidates.
Embodiment described above is only the preferred embodiment lifted for absolutely proving this utility model, and protection domain of the present utility model is not limited to this.Equivalent replacement that those skilled in the art make on this utility model basis or conversion, all within protection domain of the present utility model.Protection domain of the present utility model is as the criterion with claims.
