DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example 1: Please refer to Figure 1-5The utility model provides a technical solution: a pneumatic bore milling machine clamp. In the traditional clamp, each time the material is clamped, it is necessary to manually rotate the screw to push the clamping plate 10 to clamp and fix the material. This operation requires a certain degree of proficiency and is troublesome to operate. Excessive manual clamping force can easily cause material damage. The utility model comprises a milling machine body 1; a control panel 2 is arranged on the left side of the milling machine body 1, and two support platforms 3 are arranged below the inner wall of the milling machine body 1. Two support plates 4 are installed on the upper surfaces of the two support platforms 3, and the upper surfaces of the two support plates 4 are connected together. An engraving table 5 is installed, and two fixing plates 6 are installed on the upper surface of the engraving table 5. Drive motors 7 are installed on the opposite side surfaces of the two fixing plates 6. Clamping components are provided at the output ends of the two drive motors 7. Buffer components are provided on the opposite side surfaces of the two fixing plates 6. The clamping components include a threaded rod 8, one end of the threaded rod 8 is fixed to the output end of the drive motor 7, a threaded cylinder 9 is threadedly installed on the rod wall of the threaded rod 8, and a clamping plate 10 is installed at one end of the threaded cylinder 9. Two limit blocks 13 are installed on the lower surface of the clamping plate 10, and two limit grooves 13 are provided below the inner wall of the fixing plate 6. 4, two limit blocks 13 are respectively slidably mounted on the inner walls of the corresponding limit grooves 14, a groove 11 is opened on one side of the outer wall of the clamping plate 10, and a pressure sensor 12 is arranged on the inner wall of the groove 11. The buffer assembly includes two limit cylinders 19, one end of each of the two limit cylinders 19 is fixed to one side of the outer wall of the fixed plate 6, a buffer spring 17 is installed on one side of the inner wall of the two limit cylinders 19, and a sliding plate 16 is installed on the other end of each of the two buffer springs 17, and a limit rod 15 is installed on one side of the outer wall of each of the two sliding plates 16, and the other ends of the two limit rods 15 pass through one side of the outer wall of the fixed plate 6. A plurality of sliding plates 16 are fixed to the outer wall of the clamping plate 10 and are slidably installed on the inner walls of the corresponding limit cylinders 19. The material is clamped and fixed by the clamping assembly in cooperation with the pressure sensor 12. The process is automatically clamped and fixed without manual adjustment. The size of the material clamping force is judged by the pressure sensor 12, which makes it more convenient to fix the material next time. The clamping operation is simple and the possibility of damage to the material during the clamping process is prevented. The buffer space during the clamping process of the clamping plate 10 is controlled by the buffer assembly, which enhances the clamping stability and further reduces the possibility of damage to the material clamping.

[0025] The working principle is as follows: in order to improve the diversity of the functions of the milling machine fixture, the device can fix materials of different specifications while fixing the materials, thereby improving the practicality of the device. Before the milling machine body 1 is started, the materials are first placed together inside the fixed plate 6. After the materials are neatly stacked, the driving motor 7 is controlled by the control panel 2 to start rotating, and the threaded rod 8 is also driven to rotate together. While rotating, the threaded rod 8 is driven to rotate along the inner wall of the threaded cylinder 9. While rotating, the moving position of the clamping plate 10 is limited by the limit block 13, so that the two clamping plates 10 move to the opposite side. While moving, the corresponding limit rod 15 and the sliding plate 16 are also moved together, and the buffer spring 17 is compressed at the same time, which plays a good buffering role to prevent the possibility of damage to the equipment caused by moving too fast. While moving, the sliding plate 16 is further limited by the limit cylinder 19, thereby improving the stability of the material fixation, thereby realizing the clamping and fixing of the material. While clamping and fixing, the pressure data is received by the pressure sensor 12, so that it is convenient to process the same specification material next time, and it is convenient to fix the material quickly, thereby improving the processing efficiency.

[0026] Example 2: Figure 5 As shown, in order to further improve the diversity of material processing specifications, two mounting plates 20 are commonly installed on the upper surfaces of the two support platforms 3, and two bidirectional screw rods 21 are rotatably installed on the opposite side surfaces of the two mounting plates 20. The rod walls of the two bidirectional screw rods 21 are threadedly installed with two threaded blocks 22. The lower surfaces of the plurality of threaded blocks 22 are each installed with a slider 26, and a slide rail 27 is slidably installed on the inner wall of a corresponding group of sliders 26. The lower surfaces of the two slide rails 27 are respectively fixed to the upper surfaces of the corresponding support platforms 3. An adjusting motor 25 is installed on the right end of the front bidirectional screw rod 21, and a driving wheel 23 is installed on the left ends of the two bidirectional screw rods 21 through a first rotating shaft. The two driving wheels 23 are rotatably connected together through a gear belt 24. The two mounting plates The upper surface of 20 is fixed to the lower surface of the engraving table 5. Two limit openings 28 are provided on the upper surface of the engraving table 5. The upper parts of the outer walls of the plurality of threaded blocks 22 are slidably mounted on the inner walls of the corresponding limit openings 28. The two bidirectional screws 21 are driven to rotate together by the control and adjustment motor 25, thereby driving the threaded blocks 22 on both sides to move along the rod wall of the bidirectional screw 21 in the opposite direction or to the opposite side, thereby driving the fixed plates 6 and the clamping plates 10 on both sides to move together. While moving, the slider 26 slides on the slide rail 27 for limiting, thereby further improving the stability of the clamping and fixing of the device. While moving, the clamping space of the material discharging table is also expanded, the diversity of processing specifications is increased, and thus the diversity of product processing is also improved.
