DETAILED DESCRIPTION

[0023] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with embodiments and drawings. The contents mentioned in the implementation modes are not intended to limit the present invention.

[0025] During actual work, a robot or a human being places the workpiece 103 on the material clamping and rotating device 2. The material clamping and rotating device 2 clamps the workpiece 103 and can drive the workpiece 103 to rotate. The Y-axis driving mechanism 3 drives the material clamping and rotating device 2 to move the workpiece 103 to the position to be processed. When it is necessary to mill the workpiece 103, the mobile driving device 8 and the Y-axis driving mechanism 3 work together. The mobile driving device 8 drives the milling device 6 to move, so that the milling device 6 mills the workpiece 103 clamped and rotated by the material clamping and rotating device 2. At the same time, as the milling device 6 mills the workpiece 103, the Y-axis driving mechanism 3 drives the material clamping and rotating device 2 to move the workpiece 103 to be milled until the milling device 6 completes the milling process of the workpiece 103. When it is necessary to turn the workpiece 103, the mobile driving device 8 and the Y-axis driving mechanism 3 work together. Device 8 drives the turning device 7 to move, so that the turning device 7 turns the workpiece 103 clamped and rotated by the material clamping and rotating device 2. At the same time, as the turning device 7 turns the workpiece 103, the Y-axis driving mechanism 3 drives the material clamping and rotating device 2 to move together with the workpiece 103 being turned, until the turning device 7 completes the turning process of the workpiece 103; when the workpiece 103 needs to be ground, the grinding device 1 grinds the workpiece 103 clamped and rotated by the material clamping and rotating device 2. According to the shape of the workpiece 103, during the process of the grinding device 1 grinding the workpiece 103, the Y-axis driving mechanism 3 and the X-axis driving mechanism 5 work together, the Y-axis driving mechanism 3 drives the material clamping and rotating device 2 to move together with the workpiece 103, and the X-axis driving mechanism 5 drives the grinding device 1 to move close to or away from the workpiece 103, until the grinding device 1 completes the grinding process of the workpiece 103.

[0026] The structural design of the present invention is reasonable. By integrating turning, milling and grinding, the structure is compact, the space is small, and the space utilization rate is improved. At least one processing method among turning, milling and grinding can be selected according to the actual processing requirements of the workpiece 103, so that multiple processes of turning, milling and grinding can be completed on one device. It is flexible to use, has good versatility, and a wide range of applications. It improves the efficiency and quality of processing the workpiece 103, reduces the labor intensity of processing the workpiece 103, and shortens the processing cycle.

[0027] In this embodiment, the grinding device 1 includes a grinding seat 11, a rotation drive mechanism 12 and two grinding mechanisms 13. The rotation drive mechanism 12 is drivingly connected to the output end of the X-axis drive mechanism 5. The two grinding mechanisms 13 are both installed on the grinding seat 11. The two grinding mechanisms 13 are centrally symmetrically arranged. The rotation drive mechanism 12 is used to drive the grinding seat 11 to rotate.

[0028] When the workpiece 103 needs to be ground, the grinding mechanism 13 grinds the workpiece 103. According to the actual grinding requirements, the rotation drive mechanism 12 can drive the grinding seat 11 to drive the two grinding mechanisms 13 to rotate the set angle to change the angle at which the grinding mechanism 13 grinds the workpiece 103. Since the two grinding mechanisms 13 are centrally symmetrically arranged, the two grinding mechanisms 13 work independently without interfering with each other, so the two grinding mechanisms 13 have two usage modes: 1) the two grinding mechanisms 13 grind the two workpieces 103 respectively, that is, one grinding mechanism 13 grinds the workpieces 103 clamped and rotated by the clamping rotating device 2. The workpiece 103 is ground, and the other grinding mechanism 13 grinds the external workpiece 103, thereby improving the efficiency of grinding the workpiece 103; 2), one grinding mechanism 13 is in a grinding state, and the other grinding mechanism 13 is in a standby state. The rotating drive mechanism 12 drives the two grinding mechanisms 13 to rotate 180° to realize the exchange of the positions of the two grinding mechanisms 13. Without stopping the machine, one of the grinding mechanisms 13 can be maintained, which is convenient for maintenance, and in the process of maintaining one grinding mechanism 13, the other grinding mechanism 13 will not be delayed to grind the workpiece 103 normally. Through the central symmetric arrangement of the two grinding mechanisms 13, the grinding angle of the workpiece 103 is adjustable, which not only allows the operator to choose the appropriate use method according to actual needs, but also has various functions, flexible use, good versatility, wide range of use, high grinding efficiency, and can also maintain one of the grinding mechanisms 13 without stopping the machine, which is convenient for maintenance and strong practicality.
