Detailed Description
The principles and features of the present utility model are described below with reference to fig. 1 through 4, the examples being provided for illustration only and not for limitation of the scope of the utility model.
A grinding clamp for a brake disc comprises a supporting cylinder 1, a pull rod 2, a fixed disc 4, a positioning sleeve 5, a positioning disc 7 and a supporting shell 8.
The supporting cylinder 1 is conical and is provided with a hollow inner cavity. The support housing 8 has a hollow cylindrical shape. The bottom of support section of thick bamboo 1 is provided with flange portion, the top of support casing 8 is provided with flange portion, support section of thick bamboo 1 and support casing 8 pass through flange portion connects fixedly. The pull rod 2 penetrates through the support cylinder 1 and the support shell 8 and is in sliding connection with the support cylinder 1. One end of the top of the pull rod 2 extending out of the supporting cylinder 1 is provided with an expanding part 3, and the expanding part 3 is a main pressing part. The bottom of fixed disk 4 is connected with the top of support section of thick bamboo 1, fixed disk 4 is used for connecting spacer bush 5 and positioning disk 7. The fixed disk 4 is provided with an annular groove 13, and the bottom of the positioning disk 7 extends into the groove 13. Specifically, guide posts 14 are arranged in the groove 13 along the circumferential array, a guide sleeve 15 is arranged on the bottom surface of the positioning disk 7, the guide posts 14 are inserted into the guide sleeve 15, a gasket 16 is arranged between the guide sleeve 15 and the bottom surface of the groove 13, and the fixing disk 4 and the positioning disk 7 are fixed through bolts. The positioning plate 7 is provided with a top surface B for positioning the workpiece 6, and the relative height of the top surface B can be adjusted by adjusting the thickness of the gasket 16. The pull rod 2 passes through the positioning sleeve 5 and is in sliding connection with the positioning sleeve 5, and the positioning sleeve 5 is provided with a circumferential side wall A for positioning the workpiece 6. Referring to the coordinate system shown in fig. 1, the top surface B is a plane, and three degrees of freedom of the workpiece 6, that is, a rotational degree of freedom in the X direction, a rotational degree of freedom in the Y direction, and a movement degree of freedom in the Z direction, are restricted in the jig; the side wall A is equivalent to a long cylindrical pin, can limit two degrees of freedom of the workpiece 6, namely a moving degree of freedom in the X direction and a moving degree of freedom in the Y direction, and the grinding processing of the disc workpiece 6 does not need to limit the rotating degree of freedom in the Z direction, so that the complete positioning can be satisfied through the positioning sleeve 5 and the positioning disc 7. Referring to fig. 4, the clamping surface C, the first positioning surface D, the second positioning surface E, and the sidewall a contacts the first positioning surface D during positioning; the top surface B is contacted with the second positioning surface E; when clamping, the ground of the expansion part 3 is in contact with the clamping surface C.
