Abstract
Description
Technical Field
[0001] This utility model relates to the field of electric spindle measurement technology, specifically to an electric spindle measurement fixture. Background Technology
[0002] With the continuous development of high-speed cutting technology and high-speed machine tools, the performance and precision requirements of electric spindles are constantly increasing. Magnetic ring encoders, as a commonly used angle measurement device, play a crucial role in electric spindle measurement fixtures. To ensure accurate installation and efficient operation of the magnetic ring encoder, the height of the mounting surface needs to be measured in advance, and the installation height of the disc motor calculated accordingly.
[0003] Existing electric spindle measuring fixtures are often equipped with multiple sensors, such as laser rangefinders and displacement sensors, to measure the height of the mounting surface and calculate the subsequent motor mounting height. While these sensors can provide high-precision measurement results, the use of multiple sensors also significantly increases the cost of the measuring fixture. In addition, the integration of multiple sensors increases the complexity and maintenance difficulty of the fixture, reducing its efficiency and reliability. Therefore, we propose an electric spindle measuring fixture to solve the above problems. Utility Model Content
[0004] (a) Technical problems to be solved
[0005] To address the shortcomings of existing technologies, this utility model provides an electric spindle measuring fixture, which solves the problems mentioned in the background section.

An adjusting plate is threaded onto the lead screw. A U-shaped plate is fixedly connected to one side of the adjusting plate. A first screw rod is rotatably connected between the two inner walls of the U-shaped plate. A connecting rod is threaded onto the first screw rod. The end of the connecting rod extends outside the U-shaped plate and is welded to a contact block. A scale plate is fixedly connected to one side of the U-shaped plate. A pointer is fixedly connected to one side of the connecting rod. The end of the first screw rod extends outside the U-shaped plate and is welded to a second knob.
[0009] Furthermore, limit holes are provided on both the front and rear inner walls of the spiral plate, and limit blocks are slidably connected to the limit holes. One side of the limit block is fixedly connected to the other side of the connecting rod.

[0014] (III) Beneficial Effects
[0015] Compared with the prior art, this utility model provides an electric spindle measuring fixture, which has the following beneficial effects:
[0016] This invention fixes an L-shaped plate to the electric spindle body. Rotating the second knob in the forward direction moves the connecting rod via the first screw, which in turn moves the contact block and pointer. When the contact block contacts the first measuring surface, the data indicated by the pointer on the scale is recorded. Rotating the second knob in the reverse direction resets the contact block via the first screw and connecting rod. Rotating the first knob then moves the adjusting plate via the lead screw, which in turn moves the contact block via the U-shaped plate, moving it to one side of the second measuring surface. Rotating the second knob in the forward direction again moves the connecting rod via the first screw, which in turn moves the contact block and pointer. When the contact block contacts the second measuring surface, the data indicated by the pointer on the scale is recorded. By comparing the pointer data on the scale during the two measurements, the distance between the first and second measuring surfaces can be calculated, thus determining the height of the mounting disc motor. This achieves accurate measurement with a simple structure and low cost. Attached Figure Description

The end of the lead screw 6 extends outside the L-shaped plate 4 and is fixedly connected to a first knob 7. An adjusting plate 8 is threadedly connected to the lead screw 6. A U-shaped plate 9 is fixedly connected to one side of the adjusting plate 8. A U-shaped plate 9 is rotatably connected between the two inner walls of the U-shaped plate 9. A first screw 10 is provided, with a connecting rod 11 threaded onto it. The end of the connecting rod 11 extends beyond the U-shaped plate 9 and is welded with a contact block 13. A scale plate 14 is fixedly connected to one side of the U-shaped plate 9, and a pointer 15 is fixedly connected to one side of the connecting rod 11. A second knob 12 is welded to the end of the first screw 10, extending beyond the U-shaped plate 9. The L-shaped plate 4 is fixed to the electric spindle body 1. Then, the second knob 12 is rotated in the forward direction. The second knob 12 drives the connecting rod 11 to move via the first screw 10. The connecting rod 11 drives the limiting block 17 to the corresponding limiting hole 16. Sliding upwards, the connecting rod 11 drives the contact block 13 and pointer 15 to move. When the contact block 13 contacts the first measuring surface 2 on the electric spindle body 1, the data indicated by the pointer 15 on the scale plate 14 is recorded. Then, the second knob 12 is rotated in the reverse direction. The second knob 12 resets the contact block 13 through the first screw 10 and the connecting rod 11. After resetting, the first knob 7 is rotated. The first knob 7 drives the adjusting plate 8 to move through the lead screw 6. The adjusting plate 8 drives the contact block 13 to move through the U-shaped plate 9, so that the contact block 13 moves to one side of the second measuring surface 3. Then, the second knob is rotated in the forward direction. 12. The second knob 12 drives the connecting rod 11 to move via the first screw 10. The connecting rod 11 drives the limiting block 17 to slide on the corresponding limiting hole 16. The connecting rod 11 drives the contact block 13 and the pointer 15 to move. When the contact block 13 contacts the second measuring surface 3 on the electric spindle body 1, the data of the pointer 15 pointing to the scale plate 14 is recorded. By comparing the data of the pointer 15 on the scale plate 14 during the two measurements, the distance between the first measuring surface 2 and the second measuring surface 3 can be calculated, and the height of the mounting disc motor can be obtained. This achieves accurate measurement and has a simple structure and low cost.

[0026] In some embodiments, a groove 18 is provided on the bottom inner wall of the L-shaped plate 4, and a second screw 19 is rotatably connected to the inner walls on both sides of the groove 18. The L-shaped plate 4 serves as a support.
[0027] In some embodiments, the ends of the two second screws 19 that are close to each other are fixedly connected, and the threads of the two second screws 19 are in opposite directions.

[0029] In some embodiments, the end of one of the two second screws 19 extends out of the L-shaped plate 4 and is welded with a round block 22, the round block 22 serving as a connection.
[0030] Working principle or structural principle: In use, the L-shaped plate 4 is separated from the electric spindle body 1. For fixing, the clamping plates 21 on the L-shaped plate 4 are placed on both sides of the electric spindle body 1. Then, the circular block 22 is rotated, causing the second screw 19 to rotate. The second screw 19 moves the corresponding rectangular plate 20, which in turn moves the corresponding clamping plate 21. The L-shaped plate 4 is fixed to the electric spindle body 1 by the two clamping plates 21. Next, the second knob 12 is rotated forward. The second knob 12 moves the connecting rod 11 via the first screw 10. The connecting rod 11 moves the limiting block 17 on the corresponding limiting hole 16. The connecting rod 11 moves the contact block 13 and the pointer 15. When the contact block 13 contacts the first measuring surface 2 on the electric spindle body 1, the data indicated by the pointer 15 on the scale plate 14 is recorded. Then, the second knob 12 is rotated in the reverse direction. The second knob 12 moves the first screw 10... Rod 10 and connecting rod 11 reset the contact block 13. After reset, the first knob 7 is rotated. The first knob 7 drives the adjusting plate 8 to move through the lead screw 6. The adjusting plate 8 drives the contact block 13 to move through the U-shaped plate 9, so that the contact block 13 moves to one side of the second measuring surface 3. Then, the second knob 12 is rotated in the forward direction. The second knob 12 drives the connecting rod 11 to move through the first screw 10. The connecting rod 11 drives the limiting block 17 to slide on the corresponding limiting hole 16. The connecting rod 11 drives the contact block 13 and the pointer 15 to move. When the contact block 13 contacts the second measuring surface 3 on the electric spindle body 1, the data of the pointer 15 pointing to the scale plate 14 is recorded. By comparing the data of the pointer 15 on the scale plate 14 during the two measurements, the distance between the first measuring surface 2 and the second measuring surface 3 can be calculated, and the height of the installed disc motor can be obtained. This achieves accurate measurement and has a simple structure and low cost.
