[0001] This utility model relates to the field of angle calibration technology, and in particular to a dial machining angle calibration device. Background Technology
[0002] In precision instrument manufacturing, machining, aerospace, and many other fields requiring high-precision angle measurement, the dial, as a key angle indicator and measuring element, directly determines the performance and quality of the final product through its machining accuracy and angle calibration precision.
[0003] During angle calibration, the dial needs to maintain a stable posture to ensure the accuracy of the measurement results. However, due to the lack of an effective clamping mechanism in existing devices, the dial is prone to shaking, shifting, or tilting during placement and rotation. This unstable posture will cause deviations in the angle data collected by the sensor, thereby affecting the accuracy of the calibration results. Utility Model Content
[0004] The technical problem to be solved by this utility model is that the existing effective clamping mechanism is prone to shaking, displacement or tilting during the placement and rotation of the dial. To address this, we propose a dial processing angle calibration device.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.
[0021] Reference Figures 1-5As shown, this utility model provides a technical solution: a dial processing angle calibration device, including a calibration platform 1, a calibration mechanism 2 installed on the top of the calibration platform 1, a platform 3 installed on the top of the calibration platform 1, adjusting arms 4 fixedly connected to both sides of the platform 3, an adjusting column 5 fixedly connected to the side of the adjusting arm 4 near the platform 3, an adjusting groove 6 opened inside the adjusting column 5, an arc block 7 fixedly connected to both ends of the adjusting groove 6, a rotating column 8 rotatably connected inside the arc block 7, a control groove 9 opened at both ends of the rotating column 8, a push block 10 slidably connected inside the control groove 9, and a fixedly connected [unclear text - possibly a component or component] on the side of the push block 10 away from the arc block 7. The insert rod 11 and the rotating column 8 are equipped with a clamping rod 14 inside. The clamping rod 14 has several insertion holes 16 inside. A clamping block 15 is fixedly connected to the side of the clamping rod 14 away from the adjusting column 5. The operator adjusts the position of the clamping rod 14 so that the clamping block 15 fits the scale of different sizes. At the same time, the rotating column 8 is rotated to drive the push block 10 and the insert rod 11 to move synchronously. This causes the push block 10 to release from the thicker end of the arc block 7, so that the arc block 7 squeezes the push block 10 and drives the insert rod 11 to be inserted into the insertion hole 16 for fixation. Through the above settings, the calibration stability is improved and the scale movement is prevented during calibration.
[0022] Reference Figure 5 As shown in this embodiment: the size of the insertion rod 11 is adapted to the size of the insertion hole 16, and the surface of the insertion rod 11 is inserted into the interior of the insertion hole 16. By adapting the size of the insertion rod 11 to the size of the insertion hole 16, the insertion rod 11 can be stably inserted into the insertion hole 16, avoiding the phenomenon of shaking or displacement of the rotating column 8 during use, and improving the stability and reliability of the overall structure.
[0023] Reference Figure 5 As shown in this embodiment: a return spring 17 is fixedly connected to the side of the push block 10 near the insertion rod 11, and the side of the return spring 17 away from the push block 10 is fixedly connected to the inside of the control groove 9. When the operator makes the push block 10 contact the thicker side of the arc block 7, the push block 10 pushes the return spring 17 to compress and store force, and drives the insertion rod 11 to insert into the inside of the insertion hole 16 to limit the clamping rod 14. When the operator cancels the contact between the push block 10 and the arc block 7, under the action of the rebound force of the return spring 17, the insertion rod 11 automatically moves out from the inside of the insertion hole 16, releasing the limit on the clamping rod 14, so that the operator can easily adjust the position of the clamping rod 14 to adapt to different sizes of dials.
[0024] Reference Figure 5As shown in this embodiment, the clamping block 15 is made of silicone. By making the clamping block 15 of silicone material, the friction between the clamping block 15 and the dial can be increased, thereby improving the clamping effect of the clamping block 15 on the dial and preventing the dial from sliding during processing. At the same time, the silicone material of the clamping block 15 has a certain degree of softness, which can better fit the surface of the dial and further improve the clamping stability of the clamping block 15 on the dial.
[0025] Reference Figure 5 As shown in this embodiment: sliding grooves 12 are provided on both sides of the control slot 9, and sliders 13 are fixedly connected to both sides of the push block 10. The surface of the slider 13 is slidably connected to the inside of the sliding groove 12. When the operator moves the push block 10, the push block 10 drives the slider 13 to slide inside the sliding groove 12. Through the above settings, the movement of the push block 10 can be made more stable, avoiding shaking or deviation of the push block 10 during the movement, thus improving the overall stability and reliability.
[0026] Reference Figure 5 As shown in this embodiment: the inner wall of the adjusting groove 6 is provided with two annular grooves 19, and two annular blocks 20 are fixedly connected to the outer diameter surface of the rotating column 8. The surface of the annular blocks 20 is slidably connected to the inside of the annular grooves 19. When the operator rotates the rotating column 8 inside the adjusting groove 6, the rotating column 8 drives the annular blocks 20 to slide inside the annular grooves 19. Through the above setting, the rotation of the rotating column 8 inside the adjusting groove 6 is more stable, reducing the shaking caused by rotation and improving the stability of the overall structure. At the same time, the sliding of the annular blocks 20 inside the annular grooves 19 also plays a guiding role, making the rotation trajectory of the rotating column 8 more accurate and further improving the operating efficiency of the equipment.
[0027] Reference Figure 5 As shown in this embodiment: a storage spring 18 is fixedly connected to the side of the adjustment groove 6 away from the clamping block 15. The side of the storage spring 18 away from the inside of the adjustment groove 6 is fixedly connected to the annular groove 19. When the operator rotates the rotating column 8, the rotating column 8 drives the annular block 20 to twist the storage spring 18 to store force, thereby canceling the contact between the push block 10 and the arc block 7, and simultaneously releasing the fixation between the insertion rod 11 and the insertion hole 16. When the operator releases the rotating column 8, under the action of the rebound force of the storage spring 18, the push block 10 will quickly move closer to the arc block 7 and make close contact, and at the same time, the insertion rod 11 will also be re-fixed to the insertion hole 16 under the action of the rebound force.
[0028] Working principle: By adjusting the position of the clamping rod 14, the operator aligns the clamping block 15 with dials of different sizes. Simultaneously, rotating the rotating column 8 causes the push block 10 and the insertion rod 11 to move synchronously, bringing the push block 10 into contact with the thicker end of the arc block 7. This causes the arc block 7 to press against the push block 10, thus inserting the insertion rod 11 into the insertion hole 16 for fixation. This setup improves calibration stability, preventing dial movement during calibration. The matching size of the insertion rod 11 with the insertion hole 16 ensures stable insertion, preventing the rotating column 8 from wobbling or shifting during use, thus enhancing the overall structural stability and reliability. When the operator brings the push block 10 into contact with the thicker side of the arc block 7, the push block 10 compresses and stores the return spring 17, causing the insertion rod 11 to insert into the insertion hole 16 and limit the clamping rod 14. When the operator cancels the contact between the push block 10 and the arc block 7, the insertion rod 11 automatically moves out of the insertion hole 16 under the rebound force of the return spring 17, releasing the limit on the clamping rod 14. This allows the operator to easily adjust the position of the clamping rod 14 to accommodate different scale dials. The use of silicone material for the clamping block 15 increases the friction between the clamping block 15 and the scale dial, improving the clamping effect of the clamping block 15 on the scale dial and preventing the scale dial from slipping. During processing, slippage occurs. Simultaneously, the silicone clamping block 15 possesses a certain degree of flexibility, allowing it to better conform to the surface of the dial, further improving the clamping stability of the dial. When the operator moves the push block 10, the push block 10 drives the slider 13 to slide within the slide groove 12. This configuration makes the movement of the push block 10 more stable, preventing wobbling or deviation during movement, thus improving overall stability and reliability. When the operator rotates the rotating column 8 within the adjusting groove 6, the rotating column 8 drives the ring block 20 to slide within the annular groove 19. This configuration further enhances the rotation of the rotating column 8 within the adjusting groove 6. Stability is improved by reducing shaking caused by rotation and enhancing the overall structural stability. Simultaneously, the sliding of the ring block 20 within the ring groove 19 also serves as a guide, making the rotation trajectory of the rotating column 8 more precise and further improving the equipment's operating efficiency. When the operator rotates the rotating column 8, the rotating column 8 drives the ring block 20 to twist and store energy in the energy storage spring 18, causing the contact between the push block 10 and the arc block 7 to be canceled. At the same time, the fixation between the insertion rod 11 and the insertion hole 16 is released. When the operator releases the rotating column 8, under the rebound force of the energy storage spring 18, the push block 10 will quickly approach and tightly contact the arc block 7, while the insertion rod 11 will also be re-fixed to the insertion hole 16 under the rebound force.
