[0002] The right-angle milling heads with gear disc positioning currently mostly use 5° or 2.5° per minute. This is because when one degree per minute is directly used, the teeth on the gear disc are very dense, the distance between the tooth top and the tooth root is very small, and the angle encoder is installed on the machine tool. The transmission chain on the machine tool is long, and there are gaps, errors, and resistance in the transmission, which causes the tooth tops of the lower gear disc and the tooth roots of the upper gear disc to press against each other, resulting in a situation where the clamping is not tight, affecting the accuracy of the division. Summary of the invention

[0003] In order to overcome the deficiencies of the prior art, one of the objectives of the present invention is to provide a fully automatic right-angle milling head that can achieve accurate indexing and is reliable to use.

[0004] In order to overcome the deficiencies of the prior art, a second object of the present invention is to provide a machine tool that can achieve precise indexing and is reliable in use.

[0005] One of the purposes of the present invention is achieved by the following technical solution: A one-degree-one-minute fully automatic right-angle milling head comprises an angle encoder, an upper toothed disc assembly, and a lower toothed disc assembly, wherein the upper toothed disc assembly comprises a connecting disc, an upper toothed disc, an upper mounting seat, and a male socket, wherein the upper toothed disc and the upper mounting seat are both mounted on the connecting disc, and the male socket is mounted on the upper mounting seat, and the lower toothed disc assembly comprises a lower toothed disc, a lower mounting seat, a female socket, and an elastic member, wherein the angle encoder comprises a reading head, and the reading head is arranged on one side of the lower toothed disc, the lower toothed disc is located below the upper toothed disc and meshes with the upper toothed disc, the female socket is mounted on the lower mounting seat, and the elastic member is arranged on the lower mounting seat, and the elastic member is retracted to connect the male socket to the female socket, and the female socket is electrically connected to the reading head.

[0006] Furthermore, the lower gear plate assembly also includes a guide column, which is mounted on the lower mounting seat, one end of the guide column abuts against the elastic member, and the other end of the guide column abuts against the upper mounting seat.

[0020] The upper gear plate assembly 10 includes a connecting plate 11 , an upper gear plate 12 , an upper mounting seat 13 , and a male socket 14 .

[0021] The upper gear plate 12 and the upper mounting seat 13 are both mounted on the connecting plate 11, and the male socket 14 is mounted on the upper mounting seat 13. The cable of the male socket 14 is introduced into the interior of the slide 40 from the machine tool electrical cabinet, and is connected to the male socket 14 through the groove on the connecting plate 11 to transmit the signal of the reading head 31 of the angle encoder 30.

[0022] The lower gear plate assembly 20 includes a lower gear plate 21 , a lower mounting seat 22 , a female socket 23 , an elastic member 24 , a housing 25 , and a guide column 26 .

[0023] The lower toothed disc 21 is located below the upper toothed disc 12 and meshes with the upper toothed disc 12 to achieve the purpose of positioning; the female socket 23 is installed on the lower mounting seat 22, and the elastic member 24 is arranged on the lower mounting seat 22.
