[0037] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0038] Please also read Figure 1 to Figure 2Now, the motor shaft straightening device provided by the utility model is described. The motor shaft straightening device comprises: a frame 10, a clamping mechanism 20, a straightening mechanism 30 and a detection mechanism 40. The clamping mechanism 20 is arranged on the frame 10, and is used to clamp the motor shaft to be processed. The axial direction of the clamped motor shaft is set as the first direction. The straightening mechanism 30 is slidably arranged on the frame 10 along the first direction, and has a correction part that can be extended and retracted along the radial direction of the motor shaft to be processed. The straightening mechanism 30 is used to correct the motor shaft to be processed. There are two detection mechanisms 40, and the two detection mechanisms 40 are both slidably arranged on the frame 10 along the first direction. The two detection mechanisms 40 are located on both sides of the straightening mechanism 30, and each detection mechanism 40 has a detection cavity that can be sleeved on the motor shaft. The detection mechanism 40 is used to monitor the deformation data of the motor shaft to be processed.

[0039] Compared with the prior art, the motor shaft straightening device provided in this embodiment is provided with a frame 10, on which a clamping mechanism 20 is provided, which can clamp the motor shaft to be processed and drive the motor shaft to be processed to rotate. A straightening mechanism 30 is provided, and the motor shaft to be processed can be corrected by the correction part extending and contracting along the radial direction of the motor shaft to be processed. Two detection mechanisms 40 are provided, which can be slidably sleeved on both sides of the straightening mechanism 30, and can monitor the deformation data of the motor shaft to be processed, with high straightening efficiency, high straightening accuracy, good adaptability and good practicality.

[0040] In some embodiments, the detection mechanism 40 may be implemented as follows: Figure 1 , Figure 2 See the structure shown. Figure 1 , Figure 2 Each detection mechanism 40 includes: a sliding base 41, a detection ring 42 and a detection unit 43. The sliding base 41 is slidably disposed on the first slide rail 11 disposed on the frame 10 along a first direction. The detection ring 42 is fixed on the sliding base 41 and sleeved on the motor shaft to be processed. The detection ring 42 is coaxially disposed along the axis of the motor shaft to be processed. A plurality of detection units 43 are provided, and a plurality of detection units 43 are arranged on the detection ring 42 at annular intervals along the axis of the detection ring 42. Each detection unit 43 has a detection probe extending radially from the detection ring 42 and capable of abutting against the motor shaft.

[0041] The sliding base 41 can be slidably arranged on the first slide rail 11 arranged on the frame 10 along the first direction. The detection ring 42 can be sleeved on the motor shaft to be processed and arranged coaxially with the motor shaft to be processed. The detection unit 43 can detect the deformation of the motor shaft through a detection probe that extends radially along the detection ring 42 and can abut against the motor shaft.

[0042] In some embodiments, the detection ring 42 may be configured as follows: Figure 2 , Figure 3 See the structure shown. Figure 2 , Figure 3 The detection ring 42 includes: a fixed half ring 421 and a rotating half ring 422. The fixed half ring 421 is fixed on the sliding base 41, and the axis of the fixed half ring 421 is coaxially arranged along the axis of the motor shaft to be processed. One end of the rotating half ring 422 is hinged to one end of the fixed half ring 421, and the hinge axis is arranged along the first direction, and the other end is used for detachable connection with the other end of the fixed half ring 421. The rotating half ring 422 and the fixed half ring 421 are matched to form a detection cavity.

[0043] The fixed half ring 421 can be understood as being fixed on the sliding base 41, and the fixed half ring 421 can be tilted to facilitate the entry of the motor shaft. The rotating half ring 422 can be hinged to the fixed half ring 421, and can be pitched and rotated with the first direction as the hinge axis. The rotating half ring 422 and the fixed half ring 421 can form a detection cavity after being matched.

[0044] In some embodiments, the detection unit 43 may be configured as follows: Figure 2 , Figure 3 See the structure shown. Figure 2 , Figure 3 Each detection unit 43 includes: a fixed block 431, a detection member 432 and a damping bolt 433. The fixed block 431 is fixed on the detection ring 42. The detection member 432 slides on the fixed block 431 along the radial direction of the detection ring 42. The damping bolt 433 is used to fix the position of the detection member 432 on the fixed block 431.

[0045] The fixed block 431, the detection member 432 and the damping bolt 433 can make each detection member 432 slide radially on the fixed block 431 along the detection ring 42, and the position of the detection member 432 on the fixed block 431 is fixed by the damping bolt 433, which can adapt to the correction of motor shafts of different sizes and has good adaptability.

[0046] In some embodiments, the detection element 432 may be used as follows: Figure 2 , Figure 3 See the structure shown. Figure 2 , Figure 3 , the detection part 432 is a micrometer.

[0047] The working principle of the micrometer is mainly to convert the linear displacement into the rotational motion of the pointer through gears or levers, and then read the value on the dial. Its indication range is generally 0 to 10 mm, and some models can reach 100 mm. The micrometer is a comparative measuring tool, which can only measure relative values, not absolute values ​​directly. Therefore, it is mainly used to check the dimensional accuracy and shape position error of parts.

[0048] In some embodiments, the straightening mechanism 30 may be implemented as follows: Figure 1 , Figure 2 See the structure shown. Figure 1 , Figure 2 The straightening mechanism 30 includes: a moving slider 31, a telescopic mechanism 32, a limiting slider 33 and a connecting rod 34.

The telescopic mechanism 32 has a fixed end fixed on the moving slider 31, and the telescopic end of the telescopic mechanism 32 extends downward along a vertical direction. The limiting slider 33 is slidably arranged on the first slide rail 11, is located below the motor shaft to be processed, and is spaced apart from the moving slider 31 along a vertical direction. The connecting rod 34 connects the moving slider 31 and the limiting slider 33, and is used to make the moving slider 31 and the limiting slider 33 move synchronously.

[0049] The frame 10 is provided with a second slide rail 12 for the movable slider 31 to slide, and the second slide rail 12 is spaced apart from the first slide rail 11 in the vertical direction.

[0050] The movable slider 31, the telescopic mechanism 32 and the limit slider 33 can be connected with the connecting rod 34 to make the movable slider 31, the telescopic mechanism 32 and the limit slider 33 move synchronously, so that the limit slider 33 is always located at the bottom of the telescopic mechanism 32 and can abut against the bottom of the motor shaft to prevent the correction force of the motor shaft from being too large and causing deviation.

[0051] In some embodiments, the clamping mechanism 20 may be configured as follows: Figure 1 See the structure shown. Figure 1 The clamping mechanism 20 includes: a chuck 21 and a center 22. The chuck 21 is used to clamp one end of the motor shaft to be processed and drive the motor shaft to be processed to rotate along its axis direction. The center 22 is used to connect one end of the motor shaft to be processed.

[0052] The chuck 21 is an important mechanical device for clamping the workpiece on the machine tool. It ensures the stability and precise positioning of the workpiece during the processing. The chuck 21 can drive the motor shaft to be processed to rotate. The chuck 21 is a prior art and will not be described in detail here. The top 22 is an important machine tool component in the field of mechanical processing. It is used to position and support the workpiece to ensure the accuracy of the processing. The top 22 is a prior art and will not be described in detail here.

[0053] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
