The machining efficiency is also low. To solve this problem, a mandrel positioning fixture device for milling parts has been designed. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, this utility model provides a positioning fixture device for milling mandrels. This device solves the problems of time-consuming alignment and difficult processing in traditional processing methods, ensures product quality, improves processing efficiency, and reduces labor intensity.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a positioning fixture device for milling mandrels, including a screw, a positioning seat, a positioning pin, a washer and a nut. The positioning seat is a block in the shape of a boss, and a circular through hole is provided in the center of the positioning seat. On one side of the through hole, a pin hole in the boss part of the positioning seat is provided in a vertical direction.

[0005] The screw includes an end, rod body I, and rod body II. Rod body I is located between the end and rod body II, and the end, rod body I, and rod body II are an integral structure.

[0006] After the workpiece is placed in the positioning seat, the positioning pin passes through the corresponding round hole on the workpiece and is installed in the pin hole. A washer is placed at the center of the top of the workpiece. The screw passes through the workpiece and the washer from bottom to top. The rod body II protrudes from the washer and is threadedly connected to the nut.

[0007] Furthermore, the diameter of rod I is smaller than the diameter of the end and rod II.

[0008] The beneficial effects of this utility model are as follows: This utility model overcomes the difficulties of time-consuming alignment and difficult processing in traditional processing methods, ensuring product quality, improving processing efficiency, reducing labor intensity, and providing a solid guarantee for the completion of production nodes; the milling mandrel positioning fixture device can prevent workpiece deformation and improve workpiece quality; it is easy to clamp and accurately position, simplifying complex problems and lowering the processing threshold; practical verification shows that using the milling mandrel positioning fixture device can effectively guarantee the drawing requirements, reduce the scrap rate to almost 0, and greatly increase economic benefits; moreover, the manufacturing cost of the milling mandrel positioning fixture device is low, making processing simple and fast, and effectively ensuring processing accuracy.

[0017] like Figure 1 As shown in Figure 6, a milling spindle positioning fixture device includes a screw 1, a positioning seat 2, a positioning pin 3, a washer 4, and a nut 5. The positioning seat 2 is a boss-shaped block, and a circular through hole 201 is provided at the center of the positioning seat 2. On one side of the through hole 201, a vertical pin hole 202 is provided in the boss part of the positioning seat 2.

[0018] The screw 1 includes an end 101, a rod body I 102 and a rod body II 103. The rod body I 102 is disposed between the end 101 and the rod body II 103. The diameter of the rod body I 102 is smaller than the diameter of the end 101 and the rod body II 103. The end 101, the rod body I 102 and the rod body II 103 are an integral structure.

[0019] After the workpiece 6 is placed in the positioning seat 2, the positioning pin 3 passes through the corresponding round hole on the workpiece 6 and is installed in the pin hole 202. The washer 4 is placed at the center of the top of the workpiece 6. The screw 1 passes through the workpiece and the washer 4 from bottom to top. The rod body II 103 protrudes from the washer 4 and is threadedly connected to the nut 5.

[0020] In use, the end 101 and the rod body I 102 of the screw 1 are both placed in the T-slot on the milling machine table and positioned by the T-slot on the milling machine table; the workpiece 6 is inverted and fitted into the through hole 201 of the positioning seat 2, and the positioning pin 3 is fitted through the corresponding round hole on the workpiece 6 and installed in the pin hole 202 of the positioning seat 2; the screw 1 passes through the workpiece 6, the positioning seat 2 and the washer 4, clamping the workpiece 6 together with the positioning seat 2 through the screw 1, and positioning the position of the workpiece 6 in the positioning seat 2 by the positioning pin 3; then the nut 5 is threadedly connected to the rod body II 103 of the screw 1, assembling, clamping and installing the workpiece 6 with the fixture on the machine tool. The fixture effectively supports the inner hole and outer circle.
