The lifting assembly then moves the mounting frame up and down, and the mounting frame moves the laser emitter up and down. When the laser emitter and laser receiver are aligned, the laser receiver transmits a signal to the control panel. The control panel stops the lifting motor. At this point, the motor shaft is coaxial with the center of the straightening block. A tension spring pulls the fixing plate, causing the baffle to adhere to the lower end of the motor shaft.

Description

Technical Field

[0001] This utility model relates to the field of shaft straightening fixture technology, specifically a motor shaft straightening fixture. Background Technology

[0002] A motor shaft straightening fixture is a precision device used to repair bent or deformed motor shafts caused by various reasons. This fixture ensures that the motor shaft achieves precise straightness after repair, thereby improving the motor's operating efficiency and stability. Place the motor shaft on the straightening fixture and secure it. Use a measuring system to detect the degree and location of the shaft's bending. Based on the measurement results, set the pressure or tension parameters of the straightening device. Begin the straightening process; the straightening device applies pressure or tension to the shaft. After straightening, check the straightness of the shaft to ensure it meets the requirements. Clean and maintain the equipment to prepare it for the next use.

[0003] Existing technology provides a motor shaft straightening fixture (publication number: CN220880007U). This device includes a support mechanism, a fixing mechanism fixedly connected to one side of the top of the support mechanism, and a straightening mechanism fixedly connected to the other side of the top of the support mechanism. This invention activates a laser emitter, which, under the action of multiple laser emitters, forms a crosshair positioning line at one end of a fixed frame. Based on the position of the crosshair positioning line, a cylinder is activated again to fine-tune the position of the motor shaft. Subsequently, a hydraulic cylinder is activated, causing multiple sets of straightening clamps to simultaneously approach the shaft from four directions, compressing and straightening it. By setting the length of the straightening clamps to be longer than the shaft, the straightening clamps can straighten the entire shaft in a single operation, making it easier to use and solving the problems of not being able to straighten the entire motor shaft in a single operation and the difficulty in positioning the motor shaft.

[0004] However, the device still has the following drawbacks: When using this device, a cylinder is used to adjust the height of the motor shaft, and a laser is used to form a crosshair positioning line at one end of the fixed frame. The position of the motor shaft is fixed according to the crosshair positioning line. However, manually fixing the position is prone to errors and affects the processing effect of the device. Therefore, we need to propose a motor shaft straightening fixture. Utility Model Content

[0016] 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.

[0017] Please see Figure 1-5 This utility model provides a technical solution: A motor shaft straightening fixture includes a base plate 1, a mounting frame 4 on the base plate 1, and a lifting assembly 3 on the base plate 1 for adjusting the position of the mounting frame 4. The mounting frame 4 is equipped with a detection motor 6, the detection motor 6 is equipped with a motor shaft 7, and the base plate 1 is equipped with a position detection component 8 for detecting the position of the motor shaft 7. The position detection component 8 includes a fixed plate 81 fixedly installed at the lower end of the mounting frame 4. A slide rod 82 is slidably connected inside the fixed plate 81. A tension spring 83 is sleeved on the outside of the slide rod 82. A fixed plate 84 is fixedly connected to the lower end of the slide rod 82. A laser emitter 85 is fixedly connected to the outside of the slide rod 82. A baffle 86 is fixedly connected to the upper end of the slide rod 82. The baffle 86 is in contact with the motor shaft 7. A mounting platform 9 is fixedly connected to the upper end of the base plate 1, and a laser receiver 10 for use with the laser emitter 85 is provided on the upper end of the mounting platform 9.

[0018] The lifting assembly 3 includes a lifting motor 31 fixedly installed on the upper end of the base plate 1. A screw 32 is fixedly connected to the output shaft of the lifting motor 31. An internal threaded ring 33 is threadedly connected to the outer side of the screw 32. The internal threaded ring 33 is fixedly connected to the mounting frame 4. Two symmetrically distributed guide frames 34 are fixedly connected to the lower end of the mounting frame 4. A fixed seat 35 is slidably connected to the outer side of each of the two guide frames 34. The fixed seat 35 is fixedly connected to the base plate 1.

[0019] For example, when the lifting motor 31 is turned on, it drives the screw 32 to rotate. The screw 32 and the internal threaded ring 33 have threaded movement, which controls the internal threaded ring 33 to rise and fall. The internal threaded ring 33 drives the mounting frame 4 to rise and fall. When the mounting frame 4 rises and falls, the guide frame 34 slides inside the fixed seat 35, which plays a guiding role for the mounting frame 4.

[0020] The mounting frame 4 has a fixing component 5 for fixing the detection motor 6 inside. The fixing component 5 includes a support base 51 fixedly installed inside the mounting frame 4, which contacts the detection motor 6. Two symmetrically distributed mounting plates 52 are fixedly connected inside the mounting frame 4. A first telescopic rod 53 is provided on the side wall of each mounting plate 52. A first pressure block 54 is fixedly connected to the output end of each first telescopic rod 53, which contacts the detection motor 6. A second telescopic rod 55 is fixedly connected to the inner top of the mounting frame 4. A second pressure block 56 is fixedly connected to the output end of each second telescopic rod 55, which contacts the detection motor 6.

[0021] For example, the detection motor 6 is placed on the upper end of the support base 51, and the first telescopic rod 53 and the second telescopic rod 55 are opened, and the first pressure block 54 and the second pressure block 56 fix the detection motor 6.

[0022] The upper end of the mounting platform 9 is provided with a straightening assembly 11 for straightening the motor shaft 7. The straightening assembly 11 includes a straightening block 111 fixedly installed on the upper end of the mounting platform 9. The straightening block 111 has multiple hydraulic cylinders 112 arranged in a ring inside. A straightening plate 113 is fixedly connected to the output end of the hydraulic cylinder 112 and contacts the motor shaft 7.

[0023] For example, the motor shaft 7 is inserted into the straightening block 111, and multiple hydraulic cylinders 112 are activated, and multiple straightening plates 113 press and straighten the motor shaft 7.

[0024] A control panel 2 is fixedly connected to the upper end of the base plate 1. The control panel 2 is electrically connected to the lifting motor 31, the first telescopic rod 53, the second telescopic rod 55, the laser emitter 85, the laser receiver 10, and the hydraulic cylinder 112.

[0025] For example, control panel 2 controls the starting and stopping of electrical appliances inside the device.

[0026] Working principle: When using this utility model, the detection motor 6 is placed on the upper end of the support base 51. The first telescopic rod 53 and the second telescopic rod 55 are opened, and the first pressure block 54 and the second pressure block 56 fix the detection motor 6. The motor shaft 7 is inserted into the interior of the straightening block 111. The lifting motor 31 is turned on, driving the screw 32 to rotate. The screw 32 and the internal thread ring 33 have threaded movement, controlling the internal thread ring 33 to rise and fall. The internal thread ring 33 drives the mounting frame 4 to rise and fall. When the mounting frame 4 rises and falls, the motor shaft 7 is made coaxial with the center of the straightening block 111. Multiple hydraulic cylinders 112 are turned on, and multiple straightening plates 113 press and straighten the motor shaft 7. As the diameter of the motor shaft 7 varies, the motor shaft 7 presses down on the baffle 86 to different degrees. The baffle 86 drives the slide bar 82 to descend, and the slide bar 82 drives the laser emitter 85 to descend. The laser emitter 85 is misaligned with the laser receiver 10. The lifting assembly 3 drives the mounting frame 4 to rise and fall, and the mounting frame 4 drives the laser emitter 85 to rise and fall. When the laser emitter 85 is aligned with the laser receiver 10, the laser receiver 10 transmits a signal to the control panel 2. The control panel 2 stops the lifting motor 31. At this time, the motor shaft 7 is coaxial with the center of the straightening block 111. The tension spring 83 pulls the fixing plate 84, causing the baffle 86 to stick to the lower end of the motor shaft 7.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
