As shown in fig. 1 and fig. 2, the utility model provides a special frock of sphere processing to solve above-mentioned problem. This special frock includes: the lathe tool comprises a tailstock 1, a taper sleeve 2, a rotating shaft 3, a turning tool 4, a gear 5 and a rack 6.

One end of the taper sleeve 2 is arranged in a sleeve of the tailstock 1, the rotating shaft 3 is arranged at the other end of the taper sleeve 2, and the rotating shaft 3 is longitudinally arranged, namely the rotating shaft 3 is vertical to the taper sleeve 2. The turning tool 4 and the gear 5 are both arranged on the rotating shaft 3. The rack 6 is arranged on the tool rest 7, the rack 6 corresponds to the gear 5 in position and is meshed with the gear 5. When the lathe tool is used, the tool rest 7 is arranged on a middle carriage 8 of a lathe, and when the middle carriage 8 moves, the rack 6 on the tool rest 7 is driven to move, so that the rack 6 drives the gear 5 to rotate, and then the gear 5 drives the rotating shaft 3 and the turning tool 4 arranged on the rotating shaft 3 to rotate so as to machine a workpiece 9.

Furthermore, a supporting block 20 is installed at one end of the taper sleeve 2 far away from the tailstock 1, and the supporting block 20 is installed at the left side of the middle carriage 8 of the machine tool. The rotating shaft 3 is mounted on the taper sleeve 2 through a bearing block 20, that is, the rotating shaft 3 is positioned and coupled through the bearing block 20 fixed at one end of the taper sleeve 2. The taper sleeve 2 and the supporting block 20 are welded into an integral structure. In an embodiment, a connecting rod 21 is further disposed between the taper sleeve 2 and the support block 20, one end of the connecting rod 21 is fixedly connected with the taper sleeve 2, and the other end is fixedly connected with the support block 20.

Specifically, the rotating shaft 3 is mounted on the bearing block 20 through a single-row radial ball bearing 30, that is, two rings of the single-row radial ball bearing 30 are arranged at the end of the bearing block 20. The gear 5 is mounted on the outer circle of the extension 31 of the rotating shaft 3, i.e. one end of the rotating shaft 3 extends out of the supporting block 20 and the gear 5 is fixedly mounted on the extended outer circle of the rotating shaft 3. The rack 6 is arranged on the middle carriage 8 through a tool rest 7, the tool rest 7 is of a square structure, the position of the rack 6 corresponds to the gear 5, and the gear 5 is meshed with the rack 6.

Further, lathe tool 4 passes through cutter arbor 40 and installs on pivot 3, and cutter arbor 40 is installed in 3 middle part positions of pivot department, and lathe tool 4 is fixed in on cutter arbor 40 through lathe tool anchor clamps 41, and lathe tool 4 is fixed a position by lathe tool anchor clamps 41 promptly, and lathe tool 4 is mutually perpendicular with pivot 3, can process the sphere of different diameters through the extension length of adjustment lathe tool 4.

When the lathe tool is used, a workpiece 9 rotates at a high speed along with a main shaft of the lathe to form main cutting motion, the middle planker 8 drives the tool rest to move, the tool rest 7 drives the rack 6 to move radially, the rack 6 drives the gear 5 to rotate, and the gear 5 drives the rotating shaft 3 and the lathe tool 4 installed on the rotating shaft 3 to rotate so as to machine the workpiece 9. The lathe tool and the spherical workpiece are in combined rotary motion, so that the spherical part is machined, and the feed amount can be adjusted by adjusting the rotating speed of a lathe spindle for the cutting amount of the spherical workpiece; the size of the diameter of the turning spherical surface can be adjusted slightly by adjusting the extension of the turning tool 4. The tool is not only suitable for processing the ball cover ball bowl with a small size, but also can be used for processing the ball cover ball bowls with large sizes and different shapes. Due to the adoption of gear and rack transmission, the automatic feed can be converted into the automatic feed of a turning tool, so that a product with low roughness can be processed, and the structure is simple, the manufacturing cost is low, and the product is easy to manufacture.

The present embodiment is not described in detail, and is a technique known in the art.

The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily think of various changes or substitutions within the technical scope of the present invention, and these should be covered by the scope of the present invention.
