[0023] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] Example 1: Please refer to Figs. 1 to 4 This utility model provides a technical solution: a milling machine fixture and a milling machine, comprising: a lower fixed table 1 and an upper fixed table 2, the upper fixed table 1 and the lower fixed table 2 being arranged perpendicularly in the vertical direction, the two sides of the lower fixed table 1 being slidably connected to the lower adjusting frame 3, the two sides of the upper fixed table 2 being slidably connected to the upper adjusting frame 4, a worm gear disk 5 being fixedly installed in the middle of the lower surface of the lower adjusting frame 3 and the upper adjusting frame 4, the worm gear disk 5 being incompletely disc-shaped, a worm 6 being engaged on the lower side of the worm gear disk 5, the worm 6 being rotatably installed between the lower fixed table 1 and the upper fixed table 2, the upper surface of the lower adjusting frame 3 being fixedly connected to the upper fixed table 2, and a placement plate 7 being fixedly connected to the upper surface of the upper adjusting frame 4 for placing workpieces, threaded rods 8 being rotatably installed on both sides of the upper surface of the placement plate 7, a moving block 9 being threadedly sleeved on the threaded rod 8, a clamping frame 10 being fixedly installed on one side of the moving block 9, and a clamping plate 11 being fixedly connected to one side of the clamping frame 10.

[0025] The workpiece is placed on the placement plate 7. Through the cooperation of the threaded rod 8 and the moving block 9, the position of the clamping frame 10 can be quickly adjusted to ensure that the clamping plate 11 can firmly fix the mold, which improves the stability and reliability of the fixture, reduces manual intervention, and improves work efficiency. After the workpiece is clamped stably, the worm gear 6 meshes with the worm wheel 5, which allows the worm wheel 5 to drive the lower adjusting frame 3 and the upper adjusting frame 4 to slide on the lower fixed platform 1 and the upper fixed platform 2. This allows for precise adjustment at multiple angles without frequent disassembly and assembly of the fixture, making it easy to achieve grinding and cutting operations at different angles and meeting the needs of multi-faceted mold processing.

[0026] Example 2: Based on Example 1, the lower surface of the lower fixed table 1 is fixedly connected to the moving table of the milling machine body 12. By adjusting the moving table of the milling machine body 12, the position of the workpiece can be adjusted to facilitate all-round adjustment in accordance with the workpiece angle. Both sides of the top of the lower fixed table 1 and the upper fixed table 2 are provided with arc-shaped grooves 13. The bottom plates of the lower adjusting frame 3 and the upper adjusting frame 4 are slidably connected to the arc-shaped grooves 13. The bottoms of the lower adjusting frame 3 and the upper adjusting frame 4 are both arc-shaped, so that the lower adjusting frame 3 and the upper adjusting frame 4 can be limited by the arc-shaped grooves 13. A motor 14 is fixedly installed on one outer wall of the lower fixed table 1 and the upper fixed table 2. The motor 14 is electrically connected to an external control device. The output end of the motor 14 is fixedly connected to one end of the connecting shaft 15 through a coupling. The other end of the connecting shaft 15 is fixedly connected to the worm gear 6. Both ends of the worm gear 6 are rotatably sleeved in the support seat 16. The support seat 16 provides stable support for the worm gear 6. The support seat 16 is fixedly connected to both the lower fixed table 1 and the upper fixed table 2.

[0027] When the machining angle of the workpiece needs to be adjusted, it is only necessary to control the motor 14 fixedly installed on one side of the lower fixed table 1 and the upper fixed table 2 through the external control equipment. The output end of the motor 14 drives the connecting shaft 15 to move under the connection of the coupling. The connecting shaft 15 drives the worm 6 to rotate under the limit of the support seat 16. The worm 6 then meshes with the worm wheel 5 for transmission. The worm wheel 5 is fixedly installed in the middle of the lower surface of the lower adjusting frame 3 and the upper adjusting frame 4. Thus, the worm wheel 5 can drive the lower adjusting frame 3 and the upper adjusting frame 4 to slide through the arc groove 13 opened on the lower fixed table 1 and the upper fixed table 2 respectively, thereby realizing the angle adjustment of the lower adjusting frame 3 and the upper adjusting frame 4. Without the need for frequent disassembly and assembly of the fixture, grinding and cutting operations at different angles can be easily realized, which meets the needs of multi-faceted processing of molds.

[0028] Example 3: Based on Example 2, limit seats 17 are fixedly connected to the four corners of the upper surface of the placement plate 7. The threaded rod 8 is rotatably sleeved in the limit seats 17 on both sides. The limit seats 17 provide stable support for the threaded rod 8. A handle 18 is fixedly sleeved on one end of the threaded rod 8. The handle 18 facilitates the rotation of the threaded rod 8. The threaded rod 8 has two threads with opposite directions. The moving blocks 9 are symmetrically arranged about the threaded rod 8. A limit plate 19 is provided at the bottom of the threaded rod 8. The lower surface of the limit plate 19 is fixedly connected to the upper surface of the placement plate 7. The limit plate 19 is slidably connected to one end of the limit rod 20. The other end of the limit rod 20 is fixedly connected to the lower surface of the moving block 9. A clamping frame 10 is fixedly installed between the two moving blocks 9 on the same side. The clamping plates 11 are arranged in a linear array about the clamping frame 10, and an anti-slip rubber strip 21 is fixedly connected to one side of the clamping plates 11.

[0029] When it is necessary to clamp and fix the workpiece, the workpiece is placed on the placement plate 7. By synchronously rotating the two handles 18, the threaded rod 8 fixedly connected to them is driven to move. The threaded rod 8 rotates under the limit of the limit seat 17. Since the moving block 9 is threadedly connected to the threaded rod 8, and the two threads on the threaded rod 8 have opposite directions of rotation, the two moving blocks 9 can move towards each other under the sliding limit between the limit plate 19 and the limit rod 20, thereby driving the two clamping frames 10 to move towards each other until the clamping plate 11 on the clamping frame 10 clamps the workpiece. The clamping plate 11 is fixedly connected with anti-slip rubber strips 21, which can increase the wear resistance between the workpiece and the clamping plate 11 and improve the stability of the workpiece placement. After the workpiece is processed, the workpiece can be quickly removed by rotating the threaded rod 8 in the opposite direction. This simplifies the operation steps, reduces the difficulty of operation, reduces the possibility of misoperation, and thus improves the overall safety.

[0030] In actual use, the workpiece is placed on the placement plate 7. By synchronously rotating the two handles 18, the threaded rod 8 fixedly connected to them is driven to move. With the cooperation of the moving block 9, the limiting plate 19, and the limiting rod 20, the two clamping frames 10 are driven to move towards each other until the clamping plate 11 on the clamping frame 10 clamps the workpiece. The motor 14 fixedly installed on one side of the lower fixed platform 1 and the upper fixed platform 2 can be controlled by the external control equipment. The output end of the motor 14 drives the connecting shaft 15 to move under the connection of the coupling. The connecting shaft 15 drives the worm 6 to rotate under the limit of the support seat 16. The worm 6 then meshes with the worm wheel 5 for transmission. The worm wheel 5 is fixedly installed in the middle of the lower surface of the lower adjusting frame 3 and the upper adjusting frame 4. Thus, the worm wheel 5 can drive the lower adjusting frame 3 and the upper adjusting frame 4 to slide through the arc groove 13 opened on the lower fixed platform 1 and the upper fixed platform 2 respectively, thereby realizing the angle adjustment of the lower adjusting frame 3 and the upper adjusting frame 4.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
