Therefore, there is an urgent market need to develop a fine-tuning clamping device for precision parts processing to help people solve the existing problems. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Please see Figure 1-4 An embodiment of this utility model provides a fine-tuning clamping device for precision parts machining, including a clamping table 1. A fixed plate 4 is fixedly installed on one side of the clamping table 1. A clamping plate 5 is fixedly installed on one side of the fixed plate 4 by bolts. A clamping plate 7 is provided on one side of the clamping plate 5. A movable plate 6 is fixedly installed on one side of the clamping plate 7 by bolts. A fine-tuning box 8 is provided on one side of the movable plate 6. A translation plate 9 is fixedly installed on one side of the fine-tuning box 8. An electric cylinder 19 is fixedly installed inside the fine-tuning box 8. A monitoring block 17 is fixedly installed on the push rod end of the electric cylinder 19. A transmission block 16 is provided on one side of the monitoring block 17. One end of the transmission block 16 slides out of the interior of the fine-tuning box 8 and is fixedly connected to the movable plate 6. A pressure sensor 18 is fixedly installed inside the monitoring block 17. The pressure sensor 18 is a MEMS piezoresistive force sensor. The measuring end of the pressure sensor 18 is fixedly connected to the transmission block 16.

[0024] The electric cylinder 19 inside the fine-tuning box 8 drives the monitoring block 17 to move, which in turn drives the transmission block 16 and the movable plate 6 to make fine adjustments, thus achieving precise control of the position of the clamping plate 7. This allows for fine-tuning of the clamping force, enabling operators to flexibly adjust the clamping force according to the specific needs of precision parts. This avoids deformation of parts due to excessive clamping force or displacement of parts during processing due to insufficient clamping force. At the same time, the pressure sensor 18 installed inside the monitoring block 17 can monitor the clamping force in real time and feed the data back to the control system, further improving the control accuracy of the clamping force, ensuring product quality, and increasing practicality.

[0025] Please see Figure 4 A screw box 3 is fixedly installed at the rear end above the clamping table 1. A ball screw 20 is rotatably installed inside the screw box 3. A drive motor for the ball screw 20 is provided on one side of the screw box 3. A sliding block 21 is slidably installed on the outside of the ball screw 20 through a ball nut. A transmission plate 22 is fixedly installed below the sliding block 21. The transmission plate 22 is fixedly connected to the translation plate 9.

[0026] The screw box 3 and the ball screw 20 are designed so that the sliding block 21 and the transmission plate 22 can drive the translation plate 9 to perform translational movement. This translational movement can adjust the position of the clamping plate 7, thereby realizing the clamping of precision parts and increasing practicality.

[0027] Please see Figure 1A top plate 10 is fixedly installed above the movable plate 6, and a protruding plate 12 is fixedly installed above the fine-tuning box 8. A strip plate 11 is fixedly installed on the side of the top plate 10 facing the protruding plate 12. The end of the strip plate 11 away from the top plate 10 slides through the protruding plate 12. A scale line is provided on the upper surface of the strip plate 11.

[0028] The scale lines on the strip 11 provide an intuitive visual reference for the operator, enabling the operator to know the fine-tuning position of the movable plate 6, thereby achieving precise control over the position of the clamping plate 7. Furthermore, the structural design of the strip 11 sliding through the protruding plate 12 ensures that the movable plate 6 maintains a stable movement trajectory during fine-tuning, improving the stability and reliability of the clamping device.

[0029] Please see Figure 2 The clamping table 1 has a slot 101 inside. A stabilizing plate 13 is fixedly installed below the movable plate 6. The lower end of the stabilizing plate 13 extends to the lower part of the clamping table 1 through the slot 101. Guide columns 14 are symmetrically arranged at the front and rear ends of the clamping table 1. The guide columns 14 slide through the stabilizing plate 13. Plate seats 15 are fixedly installed at both ends of the guide columns 14. The plate seats 15 are fixedly connected to the clamping table 1.

[0030] The slot 101 provides movement space for the stabilizing plate 13, enabling the movable plate 6 to maintain stable and smooth movement during fine-tuning. The sliding through design of the guide post 14 allows the stabilizing plate 13 to be guided during movement, preventing the movable plate 6 from shifting or shaking, thus improving the stability and accuracy of the clamping device. Furthermore, the fixed connection between the plate base 15 and the clamping table 1 makes the entire guiding structure more robust and reliable.

[0031] Please see Figure 1 A mounting bracket 2 is fixedly installed below the clamping table 1, and four mounting brackets 2 are provided, which are respectively located at the four corners below the clamping table 1.

[0032] The mounting bracket 2 facilitates the fixing of the clamping device to the processing equipment, improving the versatility and adaptability of the device. Furthermore, the four mounting brackets 2 are respectively located at the four corners below the clamping table 1, making the entire clamping device more stable during installation and increasing its practicality.

[0033] Working principle: When in use, the precision part is placed against one side of clamping plate 5, and the ball screw 20 is driven to rotate, which drives the sliding block 21 and the transmission plate 22 to move horizontally, so that clamping plate 7 moves horizontally and cooperates with clamping plate 5 to clamp and fix the precision part. Then, the monitoring block 17 can be moved by the electric cylinder 19 in the fine-tuning box 8. The monitoring block 17 drives the transmission block 16 and the movable plate 6 to make fine adjustments, thereby accurately controlling the position of clamping plate 7 and realizing fine adjustment of clamping force. The pressure sensor 18 in the monitoring block 17 monitors the clamping force in real time to improve the adjustment accuracy.
