Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.

In the description of the present invention, it is to be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", and the like, indicate the orientation or positional relationship indicated based on the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention.

In the present invention, unless otherwise expressly stated or limited, the terms "mounted," "connected," and "fixed" are to be construed broadly and may, for example, be fixedly connected, detachably connected, or integrally formed; can be mechanically or electrically connected; either directly or indirectly through intervening media, either internally or in any other relationship. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.

The V-shaped roller seat comprises a base 1, a front support I11, a rear support I12, a front support II 21, a rear support II 22, a mandrel I13, a mandrel II 23, a roller I14, a roller II 24, a bearing 2 and a locking nut 3, wherein two groups of supports are symmetrically arranged on the base 1, one group of supports comprise the front support I11 and the rear support I12, the other group of supports comprise the front support II 21 and the rear support II 22, the roller I14 is installed on the mandrel I13 through the bearing 2, the mandrel I13 penetrates through the front support I11 and the rear support I12 and is fixed through a gasket 4 and the locking nut 3, the roller II 24 is installed on the mandrel II 23 through the bearing 2, and the mandrel II 23 penetrates through the front support II 21 and the rear support II 22 and is fixed through the gasket 4 and the locking nut 3.

In this embodiment, fore-stock I11, after-poppet I12, fore-stock II 21 and after-poppet II 22 are V type structure, fore-stock I11, after-poppet I12, fore-stock II 21 and after-poppet II 22 welded fastening are on base 1, base 1 and two sets of support together process the completion, run through fore-stock I11 with mandrel I13 earlier, installation bearing 2 and gyro wheel I14, guarantee to rotate and penetrate after nimble after the back-poppet I12 again, with packing ring 4 and lock nut 3 with mandrel I13 fixed can, according to same step installation gyro wheel II 14, two gyro wheels of manual rotation after whole installations are accomplished, it is all nimble to ensure that both ends gyro wheel rotates.

the V-shaped roller seat can be used as an auxiliary rotary table on a vertical and horizontal machining center, can be used on a common boring machine and a drilling machine to reduce clamping time and improve working efficiency, is particularly very practical for machining holes around a cylinder cover, a valve seat and holes with various angles on a diesel engine, takes a cylinder cover of a low-speed diesel engine as an example, as shown in figure 4, the cylinder cover is a ring-shaped forge piece, and the rotating characteristics of an excircle, an inner hole and the like can be ensured by the lathe, but a fuel injector hole, a power indicating valve hole and a pneumatic valve hole are arranged on a large end face, a plurality of cooling water holes are arranged on a small end inclined plane, the holes have high precision requirements and have different angle relations with radial and axial center lines, so that one-time clamping completion cannot be realized even if the machining is carried out on the numerical control four-axis machining center, and the machining of the holes can be realized by aligning the end face angle lines, when the V-shaped roller seat is used for rotating a part, the excircle and the roller rotate through the bearing to drive the part to rotate, so that time and labor are saved, and the excircle is not damaged.

The V-shaped roller seat can reduce multiple clamping time when used on common equipment, can serve as a manual auxiliary rotating shaft on numerical control equipment, can smoothly complete the processing of parts, can greatly reduce the cost, and is very practical.
