[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1: Please refer to Figure 1-6This utility model provides the following technical solution: A high-precision rotor spindle machining fixture, comprising a main body 1, a fixed seat 2 slidably mounted on the top of the main body 1, a fixing mechanism for fixing the rotor spindle on the outer wall of the fixed seat 2, the fixing mechanism including a placement block 3 fixedly mounted on the outer wall of the fixed seat 2, and a fixing block 4 fixedly mounted on the outer wall of the placement block 3, a first drive motor 703 fixedly mounted at the end of the placement block 3, and an adjusting screw 7 rotatably connected to the placement block 3 fixedly mounted at the output end of the first drive motor 703, and a driving bevel gear 702 fixedly mounted at the end of the adjusting screw 7, an adjusting block 5 slidably connected inside the placement block 3 and threadedly connected to the adjusting screw 7, and a clamping block 501 fixedly mounted at the top of the adjusting block 5, a transmission shaft 302 rotatably mounted at the end of the placement block 3, and a driven bevel gear 303 fixedly mounted at the end of the transmission shaft 302, two sets of placement blocks 3 symmetrically arranged on the top outer wall of the fixed seat 2, and the length of the placement blocks 3 relative to the fixed seat 2. It should be set, and the spacing between the two sets of placement blocks 3 should correspond to the rotor main shaft. The fixed block 4 has a "U" shaped cross-section, and the end of the fixed block 4 that is in contact with the rotor main shaft is designed with an inclined surface. The fixed blocks 4 are evenly distributed on the outer wall of the placement block 3. The adjusting blocks 5 are evenly distributed on the outer wall of the adjusting screw 7. The outer wall of the placement block 3 has an adjusting groove 301 corresponding to the adjusting range of the adjusting block 5. The outer wall of the adjusting screw 7 has an adjusting thread 701, and the length of the adjusting thread 701 is the same as the adjusting range of the adjusting screw 7. The adjustment range of the segment block 5 is set accordingly, the clamping block 501 is set accordingly and the adjusting block 5 is set accordingly, and the clamping block 501 is designed with an inclined surface at one end that is in contact with the outer wall of the rotor main shaft. The clamping block 501 and the outer wall of the inclined end of the fixed block 4 are both provided with buffer blocks 6 at equal distances, and the buffer blocks 6 are made of rubber. The transmission shaft 302 is located between the two sets of adjusting screws 7, and the driven bevel gear 303 is symmetrically arranged at both ends of the transmission shaft 302, and the driven bevel gear 303 is meshed with the driving bevel gear 702.

[0028] When it is necessary to fix the rotor spindle, first place the rotor spindle on the outer wall of the placement block 3, start the first drive motor 703, and the output end of the first drive motor 703 drives the adjusting screw 7 to rotate. Since the adjusting block 5 and the adjusting screw 7 are connected by threads, and the adjusting block 5 is slidably connected inside the placement block 3, when the adjusting screw 7 rotates, the adjusting block 5 will move along the adjusting groove 301 opened on the outer wall of the placement block 3 under the action of the adjusting screw 7 threads. The movement of the adjusting block 5 drives the clamping block 501 fixedly installed at its top to move. At the same time, the driving bevel gear 702 at the end of the adjusting screw 7 rotates together with the adjusting screw 7. The driving bevel gear 702 and the transmission shaft 30 The driven bevel gears 303 at both ends mesh with each other, thereby driving the driven bevel gears 303 to rotate, causing the transmission shaft 302 to rotate. Because the driven bevel gears 303 are symmetrically arranged at both ends of the transmission shaft 302, the transmission shaft 302 can drive the driven bevel gears 303 at both ends to rotate synchronously, thereby realizing the synchronous rotation of the two sets of adjusting screws 7. In this way, multiple adjusting blocks 5 and clamping blocks 501 can act simultaneously to fix multiple sets of rotor spindles. The fixing block 4 has a "U" shaped cross section, with one end that is in contact with the rotor spindle being an inclined surface. Both the inclined surface of the fixing block 4 and the clamping block 501 are provided with rubber buffer blocks 6, which can better fit the spindle surface, improve the fixing stability, and avoid damage to the spindle.

[0029] Example 2: Based on Example 1, a moving mechanism is also disclosed, the specific structure of which is as follows: The bottom of the fixed base 2 is provided with a moving mechanism for adjusting the position of the fixed base 2. The moving blocks 202 are equidistantly arranged at the bottom of the fixed base 2, and the moving blocks 202 are designed in a dovetail shape. The moving blocks 202 are threadedly connected to the moving screw 8. The sliders 201 are symmetrically arranged at the bottom of the fixed base 2. The device body 1 has a moving groove 101 corresponding to the moving blocks 202 and the sliders 201. The sliders 201 are symmetrically arranged at the bottom of the fixed base 2, and the guide rod 9 is correspondingly arranged to the sliders 201. The device body 1 has a moving groove 101 corresponding to the moving blocks 202 and the sliders 201.

[0030] To adjust the position of the fixed seat 2 to suit different processing requirements, the second drive motor 801 in the moving mechanism can be activated. The output end of the second drive motor 801 drives the moving screw 8 to rotate. Since the moving block 202 at the bottom of the fixed seat 2 is threadedly connected to the moving screw 8, and the moving block 202 has a dovetail design, it slides in the moving groove 101 opened inside the main body 1 of the equipment. Therefore, when the moving screw 8 rotates, the moving block 202 will move along the moving groove 101 under the action of the thread, thereby driving the fixed seat 2 to move. At the same time, the slider 201 symmetrically arranged at the bottom of the fixed seat 2 corresponds to the guide rod 9 fixedly installed inside the main body 1. The slider 201 slides on the guide rod 9 to provide guidance for the movement of the fixed seat 2, ensuring that the fixed seat 2 moves smoothly. The dovetail-shaped moving block 202 design further enhances the stability of the fixed seat 2 when it moves, so that the entire fixture can flexibly adjust the position of the fixed seat 2 according to the actual processing situation, thereby improving the processing efficiency of the rotor spindle.
