[0002] In machining, we often encounter some special-shaped parts. There is a workpiece whose overall shape is similar to a hexahedron, but there are pits and convex parts on its surface. It is necessary to mill its two end faces to form planes at both ends. Due to its uneven surface, it is inconvenient to clamp; at the same time, the processing requirements are relatively high. The existing technology is to use a universal clamp for clamping, and then perform turning and milling of a single surface. Therefore, it is necessary to clamp twice to complete the milling of two surfaces. The processing efficiency is low. Utility Model Content

[0020] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0021] Example:

[0022] like Figure 1-Figure 3 As shown, the utility model provides a rotary milling tool, including a base 1 and a fixture. The base 1 is used to connect with the operating table of the milling machine, thereby fixing the tool to the milling machine, and further fixing the workpiece 16 to the milling machine. The fixture is arranged on the surface of the base 1. The fixture includes a base 2 and a plurality of clamps arranged on the base 2. The clamps are used to clamp the workpiece 16, and the machine base is used to connect with the base 1. The base 2 and the base 1 are provided with through holes in cooperation with each other, and locking bolts 3 are penetrated in the through holes. The base 2 and the base 1 can be connected by the locking bolts 3. The base 2 is provided with a positioning hole 5, and a positioning pin 4 is provided in the positioning hole 5. The base 1 is provided with a plurality of groups of positioning holes 5 in cooperation with the positioning hole 5 of the base 2. After the positioning holes 5 of the base 2 and the positioning holes 5 of the base 1 are aligned, the relative positions of the two can be fixed by inserting the pins. The plurality of groups of positioning holes 5 of the base 1 correspond to a plurality of positioning angles. When the base 2 is rotated to different angles, the angles of the base 2 and the base 1 can be fixed by the pins.

[0023] When the rotary milling fixture of the utility model is used, the workpiece 16 to be processed is clamped in the fixture. At the same time, the angle of the base 2 relative to the base 1 is adjusted to a suitable value and the latch is inserted. The base 2 is fixedly connected to the base 1 by the locking bolt 3, and then the workpiece 16 is fixed to the base 1. Since the base 1 is fixedly installed on the milling machine, the workpiece 16 is also fixedly installed on the milling machine at this time. The current surface of the workpiece 16 can be milled by the milling machine. Then, the other opposite surface of the workpiece 16 needs to be milled. At this time, loosen the locking bolt 3, so that the base 2 is rotated to a suitable angle, insert the latch for positioning, and then tighten the locking bolt 3. After fixing, the other surface can be processed.

[0024] This milling tool can adjust the processing angle of the workpiece 16 by rotating the base 2, thereby avoiding the need to remove the workpiece 16 for re-clamping. The number of clamping times is reduced, and the processing efficiency is also improved.

[0025] In this embodiment, the clamping plate includes an upper clamping plate 6, a side clamping plate 7, and a transverse fixed clamp 8 and a transverse movable clamp arranged opposite to each other. The transverse fixed clamp 8 is fixedly arranged on the base 2. The transverse movable clamp is slidably arranged on the base 2. The transverse movable clamp moves toward the transverse fixed clamp 8 to clamp the workpiece 16.

[0026] The upper clamping plate 6 is connected to the top of the transverse fixing clamp 8 by screws, and one end of the upper clamping plate 6 extends to the top of the gap between the transverse fixing clamp 8 and the transverse moving clamp. After the workpiece 16 is placed between the transverse fixing clamp 8 and the transverse moving clamp, the workpiece 16 can be clamped from four directions, namely, top, bottom, left, and right, by pressing the workpiece 16 downward by the upper clamping plate 6. The side clamping plate 7 is opposite to the gap between the transverse fixing clamp 8 and the transverse moving clamp and is located on the side of the gap. The rear of the workpiece 16 can be supported by the side clamping plate 7, so that the rear of the workpiece 16 can be supported when the front of the workpiece 16 is processed by the milling machine, thereby ensuring the stability of the workpiece 16 during processing.

[0027] In this embodiment, the transverse movable clamp includes a fixed seat 9 and a movable clamp plate 10. The fixed seat 9 is fixedly arranged on the base 2. The movable clamp plate 10 is provided with a thrust screw 11. The movable clamp plate 10 is arranged at the front end of the thrust screw 11, so that the thrust screw 11 can push the movable clamp plate 10 away from or close to the transverse fixed clamp 8. Specifically, the front end of the thrust screw 11 is embedded in the movable clamp plate 10 and can rotate relative to the movable clamp plate 10. The rotation of the tightening screw can drive the movable clamp plate 10 to extend and retract, thereby driving the movable clamp plate 10 to clamp or loosen the workpiece 16.

[0028] In this embodiment, the base 2 is provided with a pit. The transverse fixing clip 8 and the fixing seat 9 are both arranged inside the pit, and the pit just accommodates the transverse fixing clip 8 and the fixing seat 9. In practice, the transverse fixing clip 8 and the fixing seat 9 are both fixed to the base 2 by screws. The provision of the pit allows the transverse fixing clip 8 and the fixing seat 9 to be just embedded in the pit and cannot be loosened. In combination with the tightening of the screws, the connection between the transverse fixing clip 8 and the fixing seat 9 and the base 2 is stable and reliable. This ensures the processing accuracy.

[0029] In this embodiment, the base 1 is further provided with a side panel 12. The side clamping plate 7 is provided on the side panel 12 so that the side clamping plate 7 faces the gap between the transverse fixing clamp 8 and the movable clamping plate 10. The side panel 12 is provided with a slide groove 13. The side clamping plate 7 is provided inside the slide groove 13 and can slide along the slide groove 13. The side clamping plate 7 is provided with a strip hole 14. The side clamping plate 7 is fixed inside the slide groove 13 by a screw penetrating the strip hole 14.

[0030] When in use, the side clamping plate 7 is slid along the slide slot 13 and adjusted to a suitable position. The side clamping plate 7 is then stably fixed inside the slide slot 13 by the cooperation of the screw and the strip hole 14, and the position of the side clamping plate 7 is adjusted.

[0031] In this embodiment, both the transverse fixing clamp 8 and the movable clamp plate 10 are provided with a clamping panel 15. The clamping panel 15 is connected to the front ends of the transverse fixing clamp 8 and the movable clamp plate 10 by screws. In other words, the clamping panel 15 is replaceable. Since there are many types of workpieces 16, their surface structures are different. Therefore, the part where the clamp contacts the workpiece 16 also changes accordingly. The clamping panel 15 can be designed according to the corresponding workpiece 16, and then it can be adapted to different types of workpieces 16 by replacing the clamping panel 15, making it more compatible.

[0032] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
