Description

Technical Field

[0001] This utility model belongs to the field of motor shaft technology, specifically relating to a high-precision detection device for motor shafts. Background Technology

[0002] In the field of motor manufacturing, the dimensional accuracy of the motor shaft directly affects the assembly quality and performance of the motor. Therefore, high-precision inspection of the geometric parameters of the motor shaft is a crucial step in ensuring motor quality. Currently, common motor shaft inspection devices typically employ contact or non-contact measurement methods, such as micrometers, laser rangefinders, or optical image measuring instruments.

[0003] In actual testing, especially when measuring the length of slender shafts, the shafts are prone to tilting or shifting due to their own weight or unstable clamping, leading to increased measurement errors and affecting the accuracy of the test results. Some testing devices use fixed support structures, which cannot flexibly adjust the testing height and are difficult to adapt to the measurement needs of shafts of different lengths, increasing the complexity of the testing operation. To address this, we have designed a high-precision testing device for motor shafts to provide an alternative technical solution to the above-mentioned technical problems. Utility Model Content

[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] Reference Figure 1-8 A high-precision detection device for motor shaft includes a U-shaped support 1, a detection probe 2 is provided at the top of the U-shaped support 1, a circular rotating block 3 is rotatably connected to the bottom of the U-shaped support 1 through a bearing, a U-shaped mounting base 5 is provided at the top of the circular rotating block 3, a height detector 8 is provided inside the U-shaped mounting base 5, and a clamping mechanism for clamping the shaft is provided inside the U-shaped mounting base 5.

[0028] The bottom of the U-shaped support 1 is also equipped with an adjustment mechanism for adjusting the position and height of the U-shaped mounting base 5;

[0029] The height detector 8 can transmit the real-time height of the bottom of the motor shaft. By setting the detection probe 2, the length of the motor shaft can be detected when the detection probe 2 contacts the top of the motor shaft.

[0030] The adjustment mechanism includes a vertical threaded rod 4, the internal thread of the circular rotating block 3 is connected to the vertical threaded rod 4, the top of the vertical threaded rod 4 is fixedly connected to the U-shaped mounting base 5, and the internal sliding connection of the vertical threaded rod 4 is a vertical limiting post 6, which is located inside the U-shaped support 1 and is fixedly connected to the U-shaped support 1.

[0031] Multiple circular levers 7 are evenly distributed and fixed on the outer side of the circular rotating block 3. By moving the circular levers 7, the circular rotating block 3 can rotate inside the U-shaped support 1. The rotation of the circular rotating block 3 is connected to the vertical threaded rod 4 by the circular rotating block 3, so that the position and height of the vertical threaded rod 4 can be adjusted.

[0032] Multiple rectangular sliding grooves are evenly distributed and fixed on the outer side of the vertical limiting post 6. A rectangular slider that matches the rectangular sliding groove is fixed inside the vertical threaded rod 4. The vertical limiting post 6 and the vertical threaded rod 4 are slidably connected through the cooperation of the rectangular sliding groove and the rectangular slider. Through the setting of the vertical limiting post 6 and the vertical threaded rod 4, the vertical threaded rod 4 can slide vertically on the outer side of the vertical limiting post 6 and prevent the rotation of the vertical threaded rod 4, so that the vertical threaded rod 4 can move up and down along the axial direction of the vertical limiting post 6.

[0033] The U-shaped support 1 has a vertical through hole inside, and the diameter of the vertical through hole is larger than the diameter of the vertical threaded rod 4, so that the vertical threaded rod 4 can slide vertically inside the U-shaped support 1.

[0034] Here, by moving the circular lever 7, the circular rotating block 3 can rotate inside the U-shaped support 1. The rotation of the circular rotating block 3 is connected to the vertical threaded rod 4 by the thread, so that the vertical threaded rod 4 can slide vertically outside the vertical limit post 6, and thus the vertical threaded rod 4 can move vertically up and down inside the U-shaped support 1. The position and height of the vertical threaded rod 4 can be adjusted, so that the vertical threaded rod 4 can drive the U-shaped mounting base 5 to move vertically up and down, and thus the height of the motor shaft inside the U-shaped mounting base 5 can be adjusted.

[0035] The adjustment mechanism includes a circular rotating component 15, which is sleeved on the outside of the vertical threaded rod 4 and threadedly connected to the vertical threaded rod 4. A circular lifting plate 11 is provided on the top of the circular rotating component 15. The circular lifting plate 11 is sleeved on the outside of the vertical threaded rod 4 and slidably connected to the vertical threaded rod 4. Multiple oblique rotating columns 12 are rotatably connected to the outside of the circular lifting plate 11. A transverse sliding column 13 is rotatably connected to the top of the oblique rotating column 12 through a pin. The transverse sliding column 13 is located inside the U-shaped mounting base 5 and slidably connected to the U-shaped mounting base 5. A rectangular clamping block 14 is fixed to one end of the transverse sliding column 13.

[0036] A rectangular limiting block is fixed to one end of the circular lifting plate 11 near the vertical threaded rod 4. A rectangular limiting groove adapted to the rectangular limiting block is opened on the outer side of the vertical threaded rod 4. The circular lifting plate 11 and the vertical threaded rod 4 slide vertically through the cooperation of the rectangular limiting block and the rectangular limiting groove. Through the cooperation of the rectangular limiting block and the rectangular limiting groove, the circular lifting plate 11 can slide vertically on the outer side of the vertical threaded rod 4. The movement of the circular lifting plate 11 causes the horizontal sliding column 13 to slide inside the U-shaped mounting base 5 through the oblique rotating column 12, thereby allowing the rectangular clamping block 14 to clamp towards the motor shaft.

[0037] The circular rotating component 15 is rotatably connected to a T-shaped rotating ring 16 inside. The top of the T-shaped rotating ring 16 is fixedly connected to the circular lifting plate 11, thereby enabling the circular rotating component 15 to rotate at the bottom of the circular lifting plate 11.

[0038] A vertical sliding plate 10 is fixed to one end of the outer side of the circular lifting plate 11. A vertical light rod 9 is slidably connected inside the vertical sliding plate 10. The vertical light rod 9 is located inside the U-shaped support 1 and is fixedly connected to the U-shaped support 1. The setting of the vertical light rod 9 allows the vertical sliding plate 10 to slide vertically on the outside of the vertical light rod 9, thereby entering the vertical guide trajectory of the circular lifting plate 11.

[0039] Here, the circular rotating component 15 is rotated, allowing it to rotate outside the T-shaped rotating ring 16. The circular rotating component 15 is threadedly connected to the vertical threaded rod 4, allowing the circular lifting plate 11 to slide vertically outside the vertical threaded rod 4. The sliding of the circular lifting plate 11 is achieved through the oblique rotating column 12, allowing the transverse sliding column 13 to move laterally inside the vertical threaded rod 4. This allows the transverse sliding column 13 to drive the rectangular clamping block 14 to clamp the motor shaft, preventing the motor shaft from tilting or changing position during testing, which could lead to inaccurate testing.

[0040] The clamping mechanism can stably fix motor shafts of different diameters, preventing them from rolling or shifting during length detection, thereby improving measurement accuracy. The adjustment mechanism can flexibly adjust the position and height of the U-shaped mounting base 5 to accommodate motor shafts of different lengths, ensuring that the measuring probe 2 is always in the optimal detection position and improving detection accuracy.

[0041] Working principle: By moving the circular lever 7, the circular rotating block 3 can rotate inside the U-shaped support 1. The rotation of the circular rotating block 3 is connected to the vertical threaded rod 4 by the thread, which allows the vertical threaded rod 4 to slide vertically outside the vertical limit post 6. This allows the vertical threaded rod 4 to rise and fall vertically inside the U-shaped support 1, thus adjusting the position and height of the vertical threaded rod 4. This allows the vertical threaded rod 4 to drive the U-shaped mounting base 5 to rise and fall vertically, thereby adjusting the height of the motor shaft inside the U-shaped mounting base 5.

[0042] The circular rotating component 15 is rotated, allowing it to rotate outside the T-shaped rotating ring 16. The circular rotating component 15 is threadedly connected to the vertical threaded rod 4, allowing the circular lifting plate 11 to slide vertically outside the vertical threaded rod 4. The sliding of the circular lifting plate 11 is achieved through the oblique rotating column 12, allowing the transverse sliding column 13 to move laterally inside the vertical threaded rod 4. This allows the transverse sliding column 13 to drive the rectangular clamping block 14 to clamp the motor shaft, preventing the motor shaft from tilting or shifting during testing, which could lead to inaccurate testing.
