[0024] 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.

[0025] Please see Figure 1-5 The present invention provides the following technical solution:

[0026] A precision grinding machine tool for rotor shafts includes a base 1, a grinding assembly 4 is provided on the right side of the top of the base 1, and a fixing assembly 5 is provided on the left side of the top of the base 1.

[0027] The grinding assembly 4 includes slide rails 401 fixedly connected to both sides of the base 1. A bracket 402 is slidably connected to the outer side of the slide rails 401. A servo motor 403 is fixedly connected to the outer side of the bracket 402. A horizontal axis lead screw 404 is fixedly connected to the output end of the servo motor 403. A support seat 405 is threadedly connected to the outer side of the horizontal axis lead screw 404. A hydraulic cylinder 406 is fixedly connected to the top of the support seat 405. A fixed seat 407 is fixedly connected to the output end of the hydraulic cylinder 406. The fixed seat 407 is slidably connected to the support seat 405. A grinding head 408 is fixedly connected to the outer side of the fixed seat 407.

[0028] In this embodiment: by starting the drive motor 3 on the bottom fixing block 2 of the base 1, the drive motor 3 drives the longitudinal axis lead screw 6 to rotate, and the movable seat 7, which is threadedly connected to the longitudinal axis lead screw 6, moves accordingly. Since the movable seat 7 and the bracket 402 are fixedly connected, the bracket 402 will slide left and right on the slide rails 401 on both sides of the base 1, thereby driving the entire grinding assembly 4 to move laterally, thereby adjusting the relative position of the grinding head 408 and the rotor shaft in the horizontal direction and determining the grinding start position. Then, the servo motor 403 on the outside of the bracket 402 is started, and the horizontal axis lead screw 404 at the output end of the servo motor 403 rotates, driving the support seat 405 threadedly connected to it to move back and forth, adjusting the longitudinal position of the grinding head 408. Then, the hydraulic cylinder 406 is started, and the output end of the hydraulic cylinder 406 pushes the fixed seat 407 to slide along the support seat 405, so that the grinding head 408 on the outside of the fixed seat 407 moves closer to or further away from the rotor shaft, and precisely adjusts the grinding depth.

[0029] Specifically, such as Figure 3 As shown, the fixing component 5 includes a frame 501 fixedly connected to the top of the base 1, a support block 502 fixedly connected to the front side of the top of the frame 501, and an electric telescopic rod 503 fixedly connected to the top of the support block 502.

[0030] Specifically, such as Figure 3 As shown, a rotating center 504 is fixedly connected to the output end of the electric telescopic rod 503. A limiting plate 505 is fixedly connected to the outer side of the rotating center 504. A limiting rod 506 is fixedly connected to the outer side of the limiting plate 505. The limiting rod 506 is slidably connected to the frame 501.

[0031] Specifically, such as Figure 3 As shown, a fixed tip 507 is fixedly connected to the rear side of the frame 501. The fixed tip 507 is located behind the rotating tip 504, and a rotor shaft body 508 is provided on the outer side of the fixed tip 507.

[0032] In this embodiment: When operating the precision grinding machine for rotor shafts, the rear end of the rotor shaft body 508 is first placed against the fixed center 507 on the rear side of the frame 501. The electric telescopic rod 503 is then activated, and the rotary center 504 connected to its output end moves accordingly. When the rotary center 504 moves forward, it presses against the front end of the rotor shaft body 508, thus achieving initial fixation of the rotor shaft body 508. During the movement of the rotary center 504, the outer limiting plate 505 and the limiting rod 506 play a key role. The limiting rod 506 slides along the frame 501 to restrict the rotary center 504 to move only in a specific direction, ensuring the stability of its movement and preventing accidents caused by excessive movement of the rotary center 504. The position of the rotary center 504 can be flexibly adjusted according to the length of the rotor shaft body 508, so that rotor shaft bodies 508 of different lengths can be stably fixed between the fixed center 507 and the rotary center 504.

[0033] Specifically, such as Figure 4 As shown, a fixing block 2 is fixedly connected to the bottom plate of the base 1, a drive motor 3 is fixedly connected to the outside of the fixing block 2, a longitudinal lead screw 6 is fixedly connected to the output end of the drive motor 3, a movable seat 7 is threadedly connected to the outside of the longitudinal lead screw 6, and the movable seat 7 is fixedly connected to the bracket 402.

[0034] Specifically, such as Figure 4 As shown, a laser displacement sensor 8 is bolted to the outside of the mounting base 407, and a transmitter 9 is electrically connected to the outside of the laser displacement sensor 8.

[0035] In this embodiment: By setting a fixed block 2, a drive motor 3, a longitudinal lead screw 6, and a movable seat 7, when preparing for grinding, the drive motor 3 is started, and the drive motor 3 rotates, driving the longitudinal lead screw 6 at its output end to rotate. Since the longitudinal lead screw 6 is threadedly connected to the movable seat 7, and the movable seat 7 is fixedly connected to the bracket 402, as the longitudinal lead screw 6 rotates, the movable seat 7 will move along the direction of the lead screw, thereby pushing the bracket 402 to slide left and right on the slide rail 401. By controlling the operation of the drive motor 3, the position of the bracket 402 is precisely adjusted, thereby causing the grinding assembly 4 mounted on the bracket 402 to move laterally as a whole, adjusting the grinding head 408 to a suitable horizontal relative position with the rotor shaft body 508. By setting a laser displacement sensor 8 and a transmitter 9, when the grinding head 408 is grinding the rotor shaft body 508, the laser displacement sensor 8 uses laser measurement... Based on the principle of distance measurement, the distance between the grinding head 408 and the rotor shaft body 508 is measured in real time, and the collected distance data is transmitted to the electrically connected transmitter 9 in the form of an electrical signal. After receiving the signal, the transmitter 9 first converts the signal into a format more suitable for transmission and processing, then amplifies the signal to enhance the signal strength and reduce the loss during transmission, and finally processes the data. The processed standard signal is wirelessly transmitted to the machine tool's control system through an internal wireless module. Based on the received data, the control system analyzes and judges the deviation between the current position of the grinding head 408 and the ideal position, and then precisely controls the operation of the drive motor 3, servo motor 403 and hydraulic cylinder 406, dynamically adjusting the position of the grinding head 408 and the grinding parameters. The combination of the laser displacement sensor 8 and the transmitter 9 realizes real-time monitoring and precise control of the grinding process.

[0036] Specifically, such as Figure 5 As shown, a collection box 10 is slidably connected to the inner side of the frame 501, and a pull rod 11 is fixedly connected to the outer side of the collection box 10.

[0037] Specifically, such as Figure 5 As shown, an anti-slip pad 12 is attached to the bottom of the base 1. The anti-slip pad 12 is made of rubber.

[0038] In this embodiment: By setting up a collection box 10 and a pull rod 11, a large amount of debris will be generated during the grinding process of the rotor shaft. Under the action of gravity, these debris will fall into the collection box 10 inside the frame 501. After the grinding process is completed, the operator holds the pull rod 11 fixedly connected to the outside of the collection box 10 and pulls the pull rod 11 along the slide groove of the frame 501 to make the collection box 10 slide out of the frame 501. Then, the debris in the collection box 10 is cleaned, and the collection box 10 is pushed back into the frame 501 to prepare for the next processing. By setting up an anti-slip pad 12, the rubber anti-slip pad 12 effectively prevents the machine tool from shifting due to vibration or external force during the processing, ensuring that the machine tool always maintains a stable working state and avoiding grinding errors caused by machine tool displacement.

[0039] Working Principle: In the process of using a precision rotor shaft grinding machine, the rotor shaft body 508 to be processed is first placed on a fixed center 507, which supports the rear end of the rotor shaft body 508 and provides a stable positioning reference. Next, the electric telescopic rod 503 is activated, which then drives the rotating center 504 at its output end to move. The rotating center 504 presses against the front end of the rotor shaft body 508. At this time, the limiting plate 505 and limiting rod 506 on the outer side of the rotating center 504 are slidably connected to the frame 501, ensuring smooth movement of the rotating center 504 and enabling… The length of the rotor shaft body 508 is flexibly adjusted to stably clamp the rotor shaft body 508 between two centers. Then, the drive motor 3 is started, and the longitudinal lead screw 6 at its output end rotates accordingly. The movable seat 7, threadedly connected to the longitudinal lead screw 6, moves along the direction of the lead screw due to its rotation. The movable seat 7 is fixedly connected to the bracket 402. The bracket 402 then slides left and right on the slide rail 401, realizing the lateral movement of the entire grinding assembly 4. This adjusts the relative position of the grinding head 408 and the rotor shaft body 508 in the horizontal direction, determining the starting position of the grinding process. The servo motor 403 on the outer side of the start-up bracket 402 is activated. The horizontal axis lead screw 404 at the output end of the servo motor 403 rotates, and the support seat 405, which is threadedly connected to the horizontal axis lead screw 404, moves back and forth under the drive of the lead screw. Then, the hydraulic cylinder 406 is activated, and its output end pushes the fixed seat 407 to slide along the surface of the support seat 405. Then, the grinding head 408 mounted on the outer side of the fixed seat 407 moves closer to or further away from the rotor shaft body 508 as the fixed seat 407 moves, so as to precisely adjust the longitudinal position and grinding depth of the grinding head 408 to meet different processing requirements. During the grinding process, the laser position... The displacement sensor 8 monitors the distance between the grinding head 408 and the rotor shaft body 508 in real time and transmits the collected distance data to the transmitter 9, which is electrically connected to it. The transmitter 9 is equipped with a wireless module. Then, the transmitter 9 converts, amplifies and processes the received signal, turning it into a standard signal that is easier to transmit and process, and then transmits it to the machine tool's control system. Based on this data, the control system precisely controls the operation of the drive motor 3, servo motor 403 and hydraulic cylinder 406, and adjusts the position of the grinding head 408 and the grinding parameters in real time to ensure that the machining accuracy meets the requirements.

[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
