Described hold-down mechanism comprises that rotation coordinates and is arranged on briquetting on described base and for driving described briquetting to rotate and compressing the compression actuating unit of main shaft body, the rotation of described briquetting is parallel with the length bearing of trend of described clamping groove; Described compression actuating unit comprises the compression cylinder being fixedly mounted on described base, and the piston rod of described compression cylinder and described briquetting are articulated and connected.

Further, to be symmetrical arranged be two to described positioning tooth.

The beneficial effects of the utility model are:

Main shaft groove milling clamping positioning tool of the present utility model, by base is set, and in clamping groove, locating piece is set, when use, main shaft is placed in clamping groove, and positioning tooth is coordinated to location with the gear teeth, then utilize hold-down mechanism that main shaft is fixed, so, can easily the teeth groove of the further groove milling of needs be alignd with milling cutter, to meet the Milling Process requirement of groove, have simple in structure, the easy to operate and stable advantage of clamping.

Brief description of the drawings

In order to make the purpose of this utility model, technical scheme and beneficial effect clearer, the utility model provides following accompanying drawing to describe:

Fig. 1 is the longitudinal section view of existing a kind of main shaft;

Fig. 2 is the structural representation of the utility model main shaft groove milling clamping positioning tool 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 better understand the utility model being implemented, but illustrated embodiment is not as to restriction of the present utility model.

As shown in Figure 2, be the structural representation of the utility model main shaft groove milling clamping positioning tool embodiment. The main shaft groove milling clamping positioning tool of the present embodiment, comprise base 4, the upper surface of described base 4 is provided with clamping groove 5, the bottom of described clamping groove 5 is provided with locating piece 6, described locating piece 6 is provided with and the spacing positioning tooth 7 that coordinates and the teeth groove of the further groove milling of needs is alignd with milling cutter 9 of at least two gear teeth 2, and the both sides of described clamping groove 5 are respectively equipped with for main shaft body 1 being pressed abd fixed on to the hold-down mechanism on described locating piece 6.

The hold-down mechanism of the present embodiment comprises that rotation coordinates and is arranged on briquetting 8 on described base 4 and for driving described briquetting 8 to rotate and compress the compression actuating unit of main shaft body 1, the rotation of described briquetting 8 is parallel with the length bearing of trend of described clamping groove 5. The compression actuating unit of the present embodiment comprises the compression cylinder 10 being fixedly mounted on described base 4, the piston rod of described compression cylinder 10 and described briquetting 8 are articulated and connected, and the piston rod of the compression cylinder 10 of the present embodiment and described briquetting 8 are articulated and connected and are provided with eccentric throw between position and the rotation of briquetting 8. By the both sides at clamping groove 5, briquetting 8 is all set, can avoids main shaft body 1, in groove milling process, circular runout occurs.

Further, it is two that the positioning tooth 7 of the present embodiment is symmetrical arranged, two positioning tooths 7 respectively with two spacing cooperations of the gear teeth 2, can effectively prevent that main shaft body 1 from rotating.

The main shaft groove milling clamping positioning tool of the present embodiment, by base is set, and in clamping groove, locating piece is set, when use, main shaft is placed in clamping groove, and positioning tooth is coordinated to location with the gear teeth, then utilize hold-down mechanism that main shaft is fixed, so, can easily the teeth groove of the further groove milling of needs be alignd with milling cutter, to meet the Milling Process requirement of groove, have simple in structure, the easy to operate and stable advantage of clamping.

The above embodiment is only the preferred embodiment for absolutely proving that the utility model is lifted, and protection domain of the present utility model is not limited to this. What those skilled in the art did on the utility model basis is equal to alternative or conversion, all within protection domain of the present utility model. Protection domain of the present utility model is as the criterion with claims.
