Specifically, after the motor stator 110 is energized with current, the motor stator 110 will excite the toroidal magnetic field and generate a magnetic force action on the motor rotor 220 placed in the toroidal magnetic field, so that the motor rotor 220 rotates in the toroidal magnetic field relative to the motor stator 110, and thus the motor rotor 220 will further drive the tail end support shaft 210 to rotate, and when the tail end support shaft 210 rotates, the turntable bearing 120 drives the working disc 230 and the fixture or the workpiece disposed on the working disc 230 to rotate, so as to process the workpiece.
In one embodiment, the fixing device 100 includes a bearing seat 130 engaged with the turntable bearing 120, a housing 140, and a cover plate 150, the housing 140 surrounds the motor stator 110, one end of the housing 140 is bolted to the bearing seat 130, the other end of the housing 140 is bolted to the hydraulic cylinder end cover 330, and the cover plate 150 is bolted to an end of the hydraulic cylinder end cover 330 facing away from the housing 140. The bearing seat 130 is used for supporting the turntable bearing 120, so as to avoid the problem of reliability reduction of the connection between the tail end supporting shaft 210 and the working disc 230 caused by the shaking of the turntable bearing 120. The housing 140 is used to package the motor stator 110, the motor rotor 220, the tail end support shaft 210, the hydraulic brake 300 and other components into a whole, so as to support and protect the components. In one embodiment, the bottom of the housing 140 is integrally formed with a frame fixing plate 160, and the frame fixing plate 160 is connected to the machine tool body through a bolt, so as to realize the positioning and installation of the numerical control turntable on the machine tool body. In an embodiment, a cooling water path is further laid between the inner surface and the outer surface of the housing 140, one end of the cooling water path is used for being communicated with an external cold water pipe and being used for accessing cooling water, and the other end of the cooling water path is used for discharging the cooling water heated after use, so that all the components in the housing 140 are cooled by the cooling water with sufficient quantity all the time in the cooling water path, and the effective use of the numerical control turntable is facilitated.

Specifically, during the operation of the numerical control turntable, the electromagnetic valve controls the operation of the external oil pump, and sends pressure oil into the oil release chamber 342 through the oil release passage 332, so that the oil pressure in the oil release chamber 342 is higher than the oil pressure in the oil brake chamber 341, the piston rod 310 moves toward one side of the oil brake chamber 341 under the pushing of the pressure oil on one side of the oil release chamber 342, in other words, the piston rod 310 moves toward the direction close to the end cover 330 of the hydraulic cylinder, so that the conical outer friction ring 320 is driven by the piston rod 310 to be away from the brake part 211 of the tail end support shaft 210 until the annular conical surface is separated from the brake part 211, i.e., the constraint on the tail end support shaft 210 is removed, and thus the tail end support shaft 210 continuously rotates under the driving of the motor rotor 220, so as to drive the work disc 230 and the workpiece or jig arranged on the work disc 230 to rotate.

It should be noted that, it is common knowledge in the art that the electromagnetic valve controls the on/off of the pressure oil of the numerical control rotary table and the flow path or direction of the pressure oil, and for those skilled in the art, while knowing the flow path of the pressure oil controlled by the electromagnetic valve, it is necessary to know that the information of using a corresponding control circuit or controller to implement the action of the electromagnetic valve is hidden in the technical solution, but in the present invention, any control circuit and corresponding controller used for controlling the action of the electromagnetic valve to adjust the output of the oil pump are used in the market or in the field, and details are not repeated herein.

The deep groove ball bearing 170 is arranged between the hydraulic cylinder end cover 330 and the tail end supporting shaft 210, so that the tail end supporting shaft 210 is arranged on the hydraulic cylinder end cover 330, the shaking of the tail end supporting shaft 210 caused by uneven stress is weakened, and the working reliability of the numerical control turntable is further ensured.
Referring to fig. 3, in an embodiment, the hydraulic brake 300 further includes a guide catch 350 disposed on the hydraulic cylinder block 340, for example, the guide catch 350 is disposed on a surface of the hydraulic cylinder block 340 facing the working disc 230, the outer surface of the tapered outer friction ring 320 is provided with a catch 321 engaged with the guide catch 350, and the guide catch 350 is used for defining a movement path of the tapered outer friction ring 320. Specifically, when the limiting disc 311 of the piston rod 310 moves in the oil chamber and drives the conical outer friction ring 320 to move, the conical outer friction ring 320 moves along the length extending direction of the guide clamping plate 350 all the time under the matching of the clamping groove 321 and the guide clamping plate 350, so that the possibility that the piston rod 310 drives the conical outer friction ring 320 to rotate relative to the conical outer friction ring 320 is avoided, the stability of the structure of the numerical control turntable is improved, the effective action of the numerical control turntable is facilitated, and the service life of the numerical control turntable is prolonged.
In an embodiment, a sealing mechanism 180a is disposed at a connection portion between the cover plate 150 and the hydraulic cylinder end cover 330, and a sealing mechanism 180b is disposed at a connection portion between the working disc 230 and the turntable bearing 120, preferably, the sealing mechanism 180a and the sealing mechanism 180b are labyrinth structures, for example, a plurality of sealing grooves are formed at intervals on the hydraulic cylinder end cover 330, a plurality of flange portions inserted into the sealing grooves are disposed on the cover plate 150, and the flange portions are correspondingly clamped in the sealing grooves to form a labyrinth passage, so that the shaft seal connection between the cover plate 150 and the hydraulic cylinder end cover 330 is realized, thereby extending a flow distance when lubricating oil in the numerical control turntable leaks, and preventing dust in an environment from entering an inner cavity of the housing 140 through the labyrinth passage, further causing excessive wear of equipment, so as to further extend the service life of the numerical control turntable.
In one embodiment, an encoder 190 is disposed between the cover plate 150 and the hydraulic cylinder end cover 330 for obtaining and feeding back angle information of the fixture or the workpiece. Specifically, the encoder 190 detects rotation information of the jig or the workpiece by an optical principle, forms the rotation information into digital pulse signals, and obtains the rotation speed of the motor rotor 220 by calculating the number of the digital pulse signals.
