The pull rod connector is a small part with the length of 4-5 mm and the width of 3-4 mm, and is a precise part. The precision component is of a T-shaped structure as a whole and consists of a columnar part and a flat rectangular part. The semi-finished product before the precision part is processed is formed by combining two sections of cylindrical parts, namely one section of the semi-finished product is cylindrical, the other section of the semi-finished product is also cylindrical, and only the radius of the two sections of cylindrical parts is larger and smaller, so that the section of the semi-finished product on the central line is in a convex shape. Milling technology is needed from the semi-finished product to the finished precision part, the section with larger radius of the semi-finished product is milled in the direction vertical to the central line of the semi-finished product, and therefore, a milling device is needed when the precision part is produced.

The milling tool for the precision parts in the prior art only has the function of milling one surface by one-time operation, and because the milling operation of two surfaces of a semi-finished product is needed, the milling operation of the same precision part in the prior art needs to adopt two positioning operations. During operation, the semi-finished product is fixed on the milling device, the grinding wheel firstly mills a plane on the semi-finished product, then the semi-finished product is loosened and rotates one hundred eighty degrees, then the semi-finished product is fixed on the milling device, and the grinding wheel mills another plane on the semi-finished product. Ideally, the two planes should be parallel.

The milling operation is a manual milling mode, a worker needs to place a precise component on a station, mill a plane in one direction firstly, then fix the precise component again and mill a plane in the other direction, and obviously, the defects of manual groove milling operation are low production efficiency and high labor intensity. Meanwhile, in the process, the positioning operation is needed again between the first milling and the second milling, the manual rotating angle is not always the same every time, and the rotating angle cannot be ensured to be consistent with the set angle, so that the flat structure obtained by manual milling is not ideal enough, and the quality of a precision part is lower than the design requirement.

The fastening seat 18 is a disk-shaped structure as a whole, and one side of the fastening seat is a clamping surface with a plane structure. The fastening socket 18 is provided with a through hole in the center, the diameter of which is larger than the diameter of the screw hole in the connecting region 13, but smaller than the diameter of the screw hole in the expansion region 14. A limiting bulge 15 is arranged on the fastening seat 18 in the extending direction of the central line of the through hole, the limiting bulge 15 is of a circular structure, and the limiting bulge 15 is positioned on one side of the clamping surface on the fastening seat 18; the outer diameter of the stop boss 15 is smaller than the diameter of the screw hole in the expanded region 14.

The output shaft of the motor is inserted into the blind hole of the connecting part 19, and then a screw is screwed into the screw hole of the connecting part 19, so that the milling cutter and the motor can be assembled into the first milling assembly 8. Since the diameter of the grinding wheel 17 is larger than the diameter of the fastening seat 18 and also larger than the diameter of the clamping part 12 of the connecting seat 16, the grinding wheel 17 protrudes outside the milling cutter; the part of the grinding wheel 17 protruding outside the milling tool is the first milling insert 10 of the first milling assembly 8.

The second milling assembly 9 has the same structure and the same spatial arrangement as the first milling assembly 8 and is positioned on the translation assembly of the milling unit in a vertical manner after installation.

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, to the position motion of material position, until the material is in between the splint of anchor clamps 2, the piston rod of spacing cylinder 4 stretches out, if the position of material is too inclined to the position that spacing cylinder 4 is located then can adjust the position of material, then, the splint of anchor clamps 2 hold the material after folding, because the material just aforementioned semi-manufactured goods is formed by two sections cylinder parts combination, just one section of semi-manufactured goods is cylindricly, another section of semi-manufactured goods also is the cylinder, two sections cylindric radius is big one little, anchor clamps 2 centre gripping is on this section that the radius is less on the material. 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 and the second milling assembly 9 to move, so that the first milling blade 10 enters a first milling station, and the second milling blade 11 enters a second 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 clamp 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 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 rectangular configuration at one end of the material. Finally, the first milling insert 10 is disengaged from the first milling station and the second milling insert 11 is disengaged from the second milling station; the clamp 2 carries the material to return to the clamping station, and after the processed material is taken away, the clamp 2 is opened again and then swings for ninety degrees to be in a horizontal state, so that the next processing process is executed. Two planes formed by milling are completely parallel.
