The connection portion 40 is provided with a blind hole for receiving an output shaft of the motor. The connecting portion 40 is provided with a screw hole, and the center line of the screw hole is perpendicular to the center line of the blind hole. The clamping part is provided with a clamping surface which is of a plane structure. The middle position of the clamping part is provided with a screw hole, the cross section of the screw hole is of a trapezoidal structure and comprises a connecting area 34 provided with internal threads and an expanding area 35 without threads, and the diameter of the screw hole in the connecting area 34 is smaller than that of the screw hole in the expanding area 35. The grinding wheel 38 is a disk structure, and a circular hole is formed in the middle of the grinding wheel 38, and the diameter of the circular hole is the same as that of the screw hole in the expansion area 35. The fastening seat 39 is a disk-shaped structure as a whole, and one side thereof is a clamping surface with a planar structure. The fastening seat 39 is provided with a through hole in the central position, the diameter of which is greater than the diameter of the threaded hole in the connecting region 34, but smaller than the diameter of the threaded hole in the expanded region 35. A limiting bulge 36 is arranged on the fastening seat 39 in the extending direction of the central line of the through hole, the limiting bulge 36 is of a circular structure, and the limiting bulge 36 is positioned on one side of the clamping surface on the fastening seat 39; the outer diameter of the stop protrusion 36 is smaller than the diameter of the screw hole in the expanded region 35.

The output shaft of the motor is extended into the blind hole of the connecting part 40, and then a screw is screwed into the screw hole of the connecting part 40, so that the milling cutter and the motor can be assembled into the first milling assembly 8. Since the diameter of the grinding wheel 38 is greater than the diameter of the fastening seat 39 and also greater than the diameter of the clamping portion 33 of the connecting seat 37, the grinding wheel 38 projects outside the milling cutter; the part of the grinding wheel 38 protruding outside the milling tool is the first milling insert 10 of the first milling assembly 8.

The second milling assembly 9 and the third milling assembly 20 are identical in structure to the first milling assembly 8, but the spatial arrangement of the second milling assembly 9 is identical to that of the first milling assembly 8, and after installation, the second milling assembly 9 is vertically positioned on the milling component and the translation assembly, while the spatial arrangement of the third milling assembly 20 is not identical to that of the first milling assembly 8, and after installation, the third milling assembly 20 is horizontally positioned on the milling component and the translation assembly. The grinding wheels 38 in the second milling assembly 9, i.e. the second milling insert 11, are turned in the same horizontal plane as the first milling insert 10, but at different working heights. The first milling insert 10 and the second milling insert 11 are arranged in succession in the direction of the action of gravity, i.e. the working height of the first milling insert 10 is higher than the working height of the second milling insert 11. The first milling insert 10, the second milling insert 11 are separated in the vertical direction and also in the horizontal direction. The grinding wheel 38, i.e. the third milling insert 21, in the third milling assembly 20 is rotated in a vertical plane, so that the third milling insert 21 is perpendicular to the first milling insert 10, the second milling insert 11; the direction of the linear reciprocating motion of the grinding wheel 38 in the third milling assembly 20 is in parallel relationship with the grinding wheel 38 in the third milling assembly 20, driven by the translation assembly of the milling unit.

One end of the path of the linear reciprocating motion of the first milling insert 10 extends into the first milling station, one end of the path of the linear reciprocating motion of the second milling insert 11 extends into the second milling station and one end of the path of the linear reciprocating motion of the third milling insert 21 extends into the third milling station.

In an initial state, the limiting cylinder 4 contracts; the clamp 2 is positioned in the clamping station and swings to a horizontal state, the clamp 2 is positioned in the groove 7, the opening direction of the clamping plate of the clamp 2 is positioned in the horizontal plane, the front of the opening of the clamping plate of the clamp 2 is just the outlet of the feeding pipe 3, a material in the feeding pipe 3 is already output on the carrying surface 6, and due to the friction force between the output material and the carrying surface 6, the output material blocks other materials in the feeding pipe 3 and cannot move outwards; the first milling insert 10 is disengaged from the first milling station, the second milling insert 11 is disengaged from the second milling station and the third milling insert 21 is disengaged from the third milling station; the first milling insert 10, the second milling insert 11 and the third milling insert 21 are all rotated. Before use, sufficient material, i.e. precision parts, are added to the feed pipe 3, so that the material is arranged one after the other in the feed pipe 3.

During the use, anchor clamps 2 are under the drive of material translation subassembly, move to material position, until the material is in between the splint of anchor clamps 2, and the piston rod of spacing cylinder 4 stretches out, if the position of material is too inclined to the position that then can adjust the material of spacing cylinder 4 position, then, the material is held to the splint of anchor clamps 2 after assembling. The clamp 2 swings ninety degrees after clamping the material, so that the material is placed at a higher position, and meanwhile, the limiting cylinder 4 contracts; other materials in the material pipe are extruded outwards under the action of gravity and are placed on the carrying surface 6. Then, the material translation assembly drives the clamp 2 to enter a first milling station, the central line of the material is located in the horizontal plane and is perpendicular to the linear motion direction of the material, and the material is static at the first milling station. The translation assembly drives the first milling assembly 8, the second milling assembly 9 and the third milling assembly 20 to move, so that the first milling blade 10 enters a first milling station, the second milling blade 11 enters a second milling station, and the third milling blade 21 enters a third milling station; since the material is now located in the first milling station, the material is only subjected to the machining process by the first milling insert 10, which first milling insert 10 is brought into contact with the material in a position above the material, and finally one side of one end of the material is milled. Then, the first milling blade 10 is separated from the first milling station, the second milling blade 11 is separated from the second milling station, the third milling blade 21 is separated from the third milling station, the fixture 2 drives the material to enter the second milling station, the first milling blade 10 enters the first milling station, the second milling blade 11 enters the second milling station, the third milling blade 21 enters the third milling station, the material is only processed by the second milling blade 11, the second milling blade 1 contacts with the material at the position below the material, and finally the other side of one end of the material is milled. This results in a flat structure at one end of the material. Subsequently, the first milling insert 10 is disengaged from the first milling station, the second milling insert 11 is disengaged from the second milling station, and the third milling insert 21 is disengaged from the third milling station; the clamp 2 carries the material into a third milling station. After two times of milling, the formed plane of the surface of the material is in the horizontal plane. The clamp 2 brings the material into a third milling station. The first milling insert 10 enters a first milling station, the second milling insert 11 enters a second milling station and the third milling insert 21 enters a third milling station. Since the grinding wheel 38 in the third milling unit 20 is vertically arranged, it only rotates in a vertical plane, and the direction of the translational movement of the grinding wheel 38 in the third milling unit 20 on the translating unit of the milling unit is parallel to the grinding wheel 38 in the third milling unit 20. The third milling insert 21 is thus brought into contact with the material, which after the milling operation has been carried out forms a distinct notch in the flattened area obtained by milling, after which the first milling insert 10 is removed from the first milling station, the second milling insert 11 is removed from the second milling station and the third milling insert 21 is removed from the third milling station. Thus, the milling operation and the groove milling operation are carried out on the materials; the clamp 2 returns to the clamping station, and after the processed material is taken away, the clamp 2 is opened again and then swings ninety degrees to be in a horizontal state, so that the next processing process is executed. Here the two planes formed by milling are perfectly parallel.

The robot arm is a multi-joint manipulator or multi-freedom-degree robot device in the industrial field, can automatically execute work, and is a machine for realizing various functions by means of self power and control capacity. The end of the robot arm is a portion with a high degree of freedom, and the working portions of the robot arm are concentrated on the end.
