Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] In the description of the utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the utility model can be understood according to specific circumstances.

[0021] Please see all instructions drawings:

[0022] A lathe-milling shaft positioning device comprises a milling machine body 1, on which a motor 2 is arranged, and the motor 2 is a key component for carrying out work as a driving component of the whole; an efficient and convenient positioning component is arranged on the output end of the motor 2; the efficient and convenient positioning component comprises a fixing plate 3 located on the output end of the motor 2, and a groove 4 is arranged on the lower side of the fixing plate 3, and the groove 4 is an arc-shaped groove; a gear 1 5 is rotatably arranged on the inner bottom surface of the groove 4, and an annular gear row 1 6 is arranged on the inner side surface of the gear 1 5, and a plurality of gears 2 7 are arranged on the inner bottom surface of the groove 43 to rotate evenly around the gear 1 5, a connecting rod 8 is arranged on the connecting rod 8, and a clamping block 9 is arranged on the connecting rod 8, and the gear 2 7 and the annular gear row 1 6 are meshed with each other, and through holes 10 are symmetrically arranged on both sides of the fixing plate 3, and a gear 3 is rotatably arranged in the through hole 10 11, gear three 11 is meshed with gear one 5, and a control ring 12 is provided on the outer rotation of the fixed plate 3. When the control ring 12 is controlled to rotate, it will drive gear three 11 to rotate, and the gear three 11 drives gear one 5 to rotate, drives the annular gear row 1 6 to rotate, drives gear two 7 to rotate, drives several connecting rods 8 to rotate clockwise or counterclockwise at the same time, and drives the clamping block 9 to clamp the milling shaft; annular gear row 2 13 is provided in the control ring 12, and the annular gear row 2 13 is meshed with gear three 11. The fixed block 3 is symmetrically provided with protrusions 14, and a screw 15 is threadedly connected on the protrusion 14. A rotating block 16 is provided on the upper end of the screw 15. Rotating the rotating block 16 can drive the screw 15 to move, so that the screw 15 fixes the control ring 12 and prevents the control ring 12 from rotating.

[0023] Furthermore, an anti-skid plate 17 is provided on the inner bottom surface of the groove 4, which can increase the friction force of the clamped milling spindle.

[0024] Furthermore, a polygonal groove 18 is provided on the upper side of the rotating block 16. The polygonal groove 18 is specifically a regular hexagonal groove, which is convenient for rotating with a regular hexagonal wrench from the outside, and the fixing effect is better.

[0025] Furthermore, the control ring 12 is provided with an anti-slip ring 19 corresponding to the screw rod 15, which can increase the friction between the screw rod 15 and the control ring 12, so as to achieve a better fixing effect.

[0026] Furthermore, a safety plate 20 is provided at the opening of the fixing plate 3 corresponding to the groove 4. The safety plate 20 can block a part of the debris generated during the milling machine processing to prevent damage to the internal gears or annular gear rows.

[0027] Furthermore, the clamping block 9 is cylindrical, which is convenient for clamping and fixing milling spindles of more sizes.

[0028] Furthermore, the clamping block 9 is provided with anti-slip protrusions 21, so that the overall friction force is greater and the clamping effect is better.

[0029] Working principle:

[0030] The worker inserts the milling shaft into the groove 4 and rotates the control ring 12, so that the internal gear 1 5, gear 2 7, annular gear row 1 6 and annular gear row 2 13 rotate relative to each other, driving the clamping block 9 to clamp the milling shaft at the same time, and then fixes the movement of the control ring 12 by the screw 15. The symmetrical design here can ensure that the weight distribution on the fixed plate 3 is always located at the center of the output end of the motor 2, avoiding eccentric design.

[0031] The above describes the utility model and its implementation methods, which are not restrictive. The specific implementation method is only one of the implementation methods of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it, without departing from the purpose of the invention of the utility model, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the utility model.
