Description

Technical Field

[0001] The present invention relates to the field of machine tools, and in particular to a fully automatic right-angle milling head with one degree and one minute division and a machine tool including the above-mentioned fully automatic right-angle milling head with one degree and one minute division. Background Art

[0002] For right-angle milling heads positioned by tooth discs, 5° one-minute or 2.5° one-minute are currently used more frequently. This is because when directly using one degree and one minute division, since the teeth on the tooth disc are very dense, the distance between the tooth tip 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 relatively long, and there are gaps, errors, and resistances in the transmission, resulting in the tooth tip of the lower tooth disc and the tooth root of the upper tooth disc touching each other, and the clamping is not tight, affecting the indexing accuracy. Summary of the Invention

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

[0004] In order to overcome the deficiencies of the prior art, the second purpose 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 adopting the following technical solutions:

[0006] A fully automatic right-angle milling head with one degree and one minute division, including an angle encoder, an upper tooth disc assembly, and a lower tooth disc assembly. The upper tooth disc assembly includes a connection disc, an upper tooth disc, an upper mounting seat, and a male socket. The upper tooth disc and the upper mounting seat are both mounted on the connection disc, and the male socket is mounted on the upper mounting seat. The lower tooth disc assembly includes a lower tooth disc, a lower mounting seat, a female socket, and an elastic member. The angle encoder includes a reading head, and the reading head is arranged on one side of the lower tooth disc. The lower tooth disc is located below the upper tooth disc and meshes with the upper tooth disc. The female socket is mounted on the lower mounting seat, and the elastic member is arranged on the lower mounting seat. The elastic member expands and contracts to connect the male socket and the female socket, and the female socket is electrically connected to the reading head.

[0007] Further, the lower tooth disc assembly further includes a guide post. The guide post is mounted on the lower mounting seat. One end of the guide post abuts against the elastic member, and the other end of the guide post abuts against the upper mounting seat.

[0008] Further, the angle encoder further includes an encoder scale body and a scale body mounting seat. The scale body mounting seat is located below the lower tooth disc, and the encoder scale body is mounted on the scale body mounting seat.

[0009] Further, the lower gear disc assembly further includes a housing, the lower gear disc is mounted on the body mounting seat, and the body mounting seat is fixedly connected to the housing.

[0010] Further, the angle encoder further includes a mounting sleeve, and the reading head is mounted on the mounting sleeve.

[0011] Further, the angle encoder further includes a gland, and the gland is mounted on the mounting sleeve.

[0012] Further, the upper gear disc and the lower gear disc rotate relative to each other for indexing.

[0013] The second object of the present invention is achieved by the following technical solution:

[0014] A machine tool includes a ram and a spindle. The spindle is mounted on the ram, and further includes any one of the above-mentioned full-automatic right-angle milling heads with one-degree-one-minute division. The connecting disc is mounted on the ram.

[0015] Compared with the prior art, the full-automatic right-angle milling head with one-degree-one-minute division of the present invention includes an angle encoder, an upper gear disc assembly, and a lower gear disc assembly. The upper gear disc assembly includes a connecting disc, an upper gear disc, an upper mounting seat, and a male socket. The upper gear disc and the upper mounting seat are both mounted on the connecting disc, and the male socket is mounted on the upper mounting seat. The lower gear disc assembly includes a lower gear disc, a lower mounting seat, a female socket, and an elastic member. The angle encoder includes a reading head, and the reading head is arranged on one side of the lower gear disc. The lower gear disc is located below the upper gear disc and meshes with the upper gear disc. The female socket is mounted on the lower mounting seat, and the elastic member is arranged on the lower mounting seat. The elastic member expands and contracts to connect the male socket and the female socket, and the female socket is electrically connected to the reading head. In this application, an angle encoder is installed on the right-angle milling head to feedback the actual position of the right-angle milling head during the indexing process, achieve accurate indexing of the right-angle milling head, ensure accurate meshing of the upper gear disc and the lower gear disc, and prevent the situation of insufficient clamping, so as to achieve one-degree-one-minute division. After installing the angle encoder, the signal of the angle encoder needs to be transmitted from inside the ram to the reading head mounted on the right-angle milling head. When the right-angle milling head is indexing, the lower gear disc on the right-angle milling head and the upper gear disc on the ram will disengage. In order to transmit the signal, male and female sockets that can float up and down are designed to ensure normal signal transmission after the C-axis is released, and the use is reliable.

[0026] Figures 1-6The present invention relates to a fully automatic right-angle milling head with one-degree-one-minute division, which includes an upper gear disc assembly 10, a lower gear disc assembly 20, and an angle encoder 30.

[0027] The upper gear disc assembly 10 includes a connection disc 11, an upper gear disc 12, an upper mounting seat 13, and a male socket 14.

[0028] The upper gear disc 12 and the upper mounting seat 13 are both installed on the connection disc 11, the male socket 14 is installed on the upper mounting seat 13, and the cable of the male socket 14 is introduced into the inside of the ram 40 from the machine tool electrical cabinet and connected to the male socket 14 through the slot on the connection disc 11 to transmit the signal of the reading head 31 of the angle encoder 30.

[0029] The lower gear disc assembly 20 includes a lower gear disc 21, a lower mounting seat 22, a female socket 23, an elastic member 24, a housing 25, and a guide post 26.

[0030] The lower gear disc 21 is located below the upper gear disc 12 and meshes with the upper gear disc 12 to achieve the purpose of positioning; the female socket 23 is installed on the lower mounting seat 22, the elastic member 24 is arranged on the lower mounting seat 22, and the elastic member 24 expands and contracts to connect the male socket 14 with the female socket 23. Specifically, the elastic member 24 props up the lower mounting seat 22 and brings the female socket 23 into combination with the male socket 14 to transmit the signal; the female socket 23 is electrically connected to the reading head 31. In this embodiment, there is a signal line under the female socket 23 leading to the reading head 31.

[0031] The guide post 26 is installed on the lower mounting seat 22, one end of the guide post 26 abuts against the elastic member 24, and the other end of the guide post 26 abuts against the upper mounting seat 13.

[0032] The angle encoder 30 includes a reading head 31, an encoder scale body 32, a scale body mounting seat 33, a mounting sleeve 34, and a gland 35. The reading head 31 is arranged on one side of the lower gear disc 21, the scale body mounting seat 33 is located below the lower gear disc 21, the encoder scale body 32 is installed on the scale body mounting seat 33, the reading head 31 is installed on the mounting sleeve 34, the lower gear disc 21 is installed on the scale body mounting seat 33, the scale body mounting seat 33 is fixedly connected to the housing 25, and the gland 35 is installed on the mounting sleeve 34. When the machine tool uses the right-angle milling head for indexing, the entire right-angle milling head moves downward, and the upper gear disc 12 and the lower gear disc 21 are also disengaged, and the upper gear disc 12 and the lower gear disc 21 rotate relative to each other so as to perform indexing. Due to the action of the elastic member 24, the female socket 23 is lifted, and the female socket 23 still combines with the male socket 14, and signal interruption will not occur. When indexing the C-axis, the lower gear disc 21, the encoder scale body 32, the scale body mounting seat 33, and the housing 25 will rotate as a whole, and the mounting sleeve 34 and the reading head 31 are fixed, so that the actual angle of C-axis indexing can be clearly recorded, and the tooth root of the upper gear disc 12 and the tooth top of the lower gear disc 21 can be completely aligned, and there will be no tooth jamming phenomenon during clamping.

[0033] This application also relates to a machine tool including the above-mentioned full-automatic right-angle milling head with one-degree-one-minute division, which includes a ram 40 and a spindle 50. The spindle 50 is installed on the ram 40, and the connecting plate 11 is installed on the ram 40.

[0034] In this application, an angle encoder 30 is installed on the right-angle milling head to feedback the actual position of the right-angle milling head during the indexing process, achieving precise indexing of the right-angle milling head, ensuring that the upper tooth disc 12 and the lower tooth disc 21 can be accurately meshed without the situation of being unable to clamp tightly, thereby realizing one-degree-one-minute division. After installing the angle encoder 30, the signal of the angle encoder 30 needs to be transmitted from inside the ram 40 to the reading head 31 installed on the right-angle milling head. When the right-angle milling head is indexed, the lower tooth disc 21 on the right-angle milling head and the upper tooth disc 12 on the ram 40 will disengage. In order to transmit the signal, a male socket 14 and a female socket 23 that can float up and down are designed to ensure that the signal can be normally transmitted after the C-axis is released, and the use is reliable.

[0035] The above embodiments only represent several implementation manners of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can be made. These are all equivalent modifications and evolutions made to the above embodiments based on the essence of the present invention, and all belong to the protection scope of the present invention.
