[0044] Referring to Figure 4 As shown in the drawings, the fixed disc comprises an open slot and a through slot arranged on the open slot, the movable disc is arranged in the open slot, and the inclined block is at least partially arranged in the through slot. Through the above scheme, the inclined block is driven by the output shaft to slide along the first guide rail, thereby driving the movable disc to move along the second guide rail, so as to realize the linear reciprocating motion of the movable disc along the open slot driven by the extension and retraction of the output shaft, and realize the planar machining.

[0045] Referring to Figure 5 As shown in the drawings, the flat rotary disc further comprises a chip retaining plate fixedly connected to the edge of the open slot, and the chip retaining plate is arranged in the vertical direction of the second guide rail assembly.

Through the above scheme, it is helpful to improve the stability of the flat rotary disc structure while reducing the use cost of structural materials.

[0047] The flat rotary disc further comprises a first bearing sleeved on the first step, a second bearing sleeved on the second step, a third bearing sleeved on the third step, and a slotted nut sleeved on the fourth step, and the outer wall of the first bearing, the second bearing and the third bearing is in contact with the inner wall of the fixed sleeve. Through the above scheme, it is helpful to realize the stability of the structure.

[0048] Referring to Figure 7 As shown in the drawings, the embodiment further provides a machining machine tool comprising a bed, a column, a ram, a main shaft and a flat rotary disc according to the above scheme. The column is arranged on the bed, the ram is arranged on the column and connected to the column, and the main shaft is arranged on the ram to output power to drive the flat rotary disc to machine. Further, the embodiment provides a boring machine comprising a flat rotary disc according to the above scheme.

[0049] When the planar machining is carried out, the basic working principle of the embodiment is that the main shaft drives the output shaft to rotate to drive the spline sleeve to rotate, the spline sleeve drives the fixed disc to rotate, the movable disc is arranged in the open slot of the fixed disc and rotates with the fixed disc due to the limiting action of the two sides of the open slot, thereby driving the boring tool holder arranged on the movable disc to rotate, finally the boring tool holder rotates to drive the boring tool to rotate, and the boring hole machining is realized through the machine tool.

[0050] When the boring hole machining is carried out, the basic working principle of the embodiment is that the main shaft drives the output shaft to rotate to drive the spline sleeve to rotate, the spline sleeve drives the fixed disc to rotate, the movable disc is arranged in the open slot of the fixed disc and rotates with the fixed disc due to the limiting action of the two sides of the open slot, thereby driving the boring tool holder arranged on the movable disc to rotate, finally the boring tool holder rotates to drive the boring tool to rotate, and the boring hole machining is realized through the machine tool.

[0051] It should be noted that when the planar or boring hole machining is carried out, the rotation movement of the boring tool holder is mainly realized through the output shaft driving the spline sleeve to rotate, the spline sleeve driving the fixed disc to rotate, the fixed disc driving the movable disc to rotate, and finally the movable disc driving the boring tool holder to rotate to realize the rotation of the boring tool. Since the output shaft, the first connecting seat, the inclined block and the movable disc are sequentially fixedly connected in the rotation transmission route, the rotation transmission route can also be realized through the first sliding block seat, the inclined block and the movable disc. However, since the output shaft and the first sliding block seat are connected through screws, the connection strength is insufficient to stably drive the boring tool holder to rotate for machining, so the latter power transmission route only plays an auxiliary role and cannot be used as a separate driving mode for rotating machining of the boring tool.

[0052] The planar-rotary disc provided by the utility model has the advantages that the output shaft can drive the movable disc to rotate and realize boring hole machining or planar machining, which helps to realize the extension and retraction of the output shaft while transmitting torque, boring tool rotation and linear reciprocating movement, the structure is simpler and more reasonable, the convenience of use and the stability of operation of the planar-rotary disc are improved, and the machining requirement of a position with a large depth can be realized.

[0053] As is apparent to those skilled in the art, various modifications and changes can be made to the above-described exemplary embodiments of the present application without departing from the spirit and scope of the present application. Therefore, it is intended that the present application cover modifications and changes as long as they come within the scope of the appended claims and their equivalents.
