[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.
[0023] Reference Figures 1-4 A motor shaft straightening and testing device for motor shaft production and processing includes a pipe fitting 1, specifically a thin-walled circular hollow tube. A slot 101 is formed through the top of the pipe fitting 1, and a mounting plate 10 is slidably fitted onto the slot 101. A thin-walled wedge-shaped shell 9 is fixedly attached to the upper surface of the mounting plate 10. A reflector 24 is fixedly attached to the inner wall of the wedge-shaped shell 9. A corrugated pipe 8 is horizontally fixed to one side of the wedge-shaped shell 9, and the corrugated pipe 8 communicates with the wedge-shaped shell 9. The reflector 24 reflects light parallel to the axis of the corrugated pipe 8. A first baffle 2 is fixedly attached to one end of the pipe fitting 1, and the first baffle 2 is connected via a connecting structure. The device includes a CCD camera 5 and a connecting structure comprising a frame 3, multiple horizontal springs 6, and multiple vertical springs 7. The frame 3 is fixed to the outer wall of the first baffle 2. One end of each of the multiple horizontal springs 6 is horizontally fixed to the side wall of the CCD camera 5, and the other end of each of the horizontal springs 6 is fixed to the two inner side walls of the frame 3. One end of each of the vertical springs 7 is fixed to the top of the inner side of the frame 3, and the other end of each of the vertical springs 7 is fixed to the top of the CCD camera 5. Both the multiple horizontal springs 6 and the multiple vertical springs 7 are always in a stretched state. The lens of the CCD camera 5 is inserted into the bellows 8, and the lens of the CCD camera 5 is coaxially arranged with the bellows 8.
[0024] When inspecting the motor shaft, the CCD camera 5 indirectly captures an image of the motor shaft inside the tube 1 through the refraction of the reflector 24, in order to prevent oil and impurities on the surface of the motor shaft from contaminating the lens during operation.
[0025] The CCD camera 5 is elastically connected to the frame 3 by multiple horizontal springs 6 and vertical springs 7 in a tensile state, so as to reduce the impact of external vibrations on the CCD camera 5 during operation.
[0026] like Figure 4 and Figure 5 As shown, a conduit 11 is vertically arranged on the bottom surface of the mounting plate 10. The conduit 11 is rotatably connected to the mounting plate 10. The top of the conduit 11 is connected to the inside of the wedge-shaped housing 9. A lens 14 made of transparent material is fixed to the bottom of the conduit 11.
[0027] The reflector 24 captures an image of the motor shaft through the transparent lens 14. The lens 14 protects the reflector 24 to prevent oil and impurities from contaminating the surface of the motor shaft.
[0028] like Figures 4-6 As shown, an incomplete gear 13 is fixed to the outer wall of the conduit 11, and long racks 18 are fixed to both sides of the inner wall of the slot 101. The incomplete gear 13 matches the long racks 18. A bearing seat 15 is fixed to the bottom surface of the mounting plate 10. A spline shaft 16 is rotatably mounted in the bearing seat 15. A drive gear 17 is fixed to the end of the spline shaft 16. An end face gear 12 is fixed to the outer wall of the conduit 11. The drive gear 17 matches the end face gear 12. A second baffle 4 is fixed to the end of the pipe fitting 1. An inner spline tube 19 is rotatably mounted on the top of the second baffle 4. The spline shaft 16 is slidably fitted in the inner spline tube 19. The end of the spline shaft 19 is connected to the main shaft 20.
[0029] When the main spindle 20 rotates, it drives the inner spline tube 19 to rotate. The rotation of the inner spline tube 19 drives the spline shaft 16 to rotate. The rotation of the spline shaft 16 drives the drive gear 17 to rotate. The rotation of the drive gear 17 drives the end face gear 12 to rotate. The rotation of the end face gear 12 drives the guide tube 11 to rotate synchronously. The rotation of the guide tube 10 drives the bottom lens 14 to rotate. During the rotation process, the oil and impurities on the surface of the lens 14 will be thrown off under the action of centrifugal force, thereby preventing the oil and impurities on the surface of the lens 14 from affecting the image quality of the CCD camera 5.
[0030] During the rotation of the guide tube 10, the incomplete gear 13 will also be driven to rotate. When the incomplete gear 13 rotates between two oppositely arranged long racks 18, it will drive the mounting plate 10 to make linear reciprocating motion in the slot 101, thereby driving the reflector 24 and the lens 14 to make scanning motion along the motor axis.
[0031] like Figure 4 As shown, a large gear 22 is rotatably mounted on the second baffle 4, and a small gear 21 is fixedly connected to the outer wall of the inner spline tube 19. The large gear 22 matches the small gear 21, and a three-jaw chuck 23 is fixedly connected to the end face of the large gear 21 for clamping the motor shaft to be tested.
[0032] During the rotation of the inner spline tube 19 driven by the spindle 20, the small gear 21 on the outer wall of the inner spline tube 19 drives the large gear 22 to rotate. The rotation of the large gear 22 drives the three-jaw chuck 23 to rotate. The rotation of the three-jaw chuck 23 drives the motor shaft to be inspected to rotate, thereby completing the comprehensive imaging of the motor shaft.
[0033] Working principle: When inspecting the motor shaft, the motor shaft to be inspected is clamped in the three-jaw chuck 23.
[0034] The main shaft 20 drives the inner spline tube 19 to rotate as the power shaft. During the rotation of the inner spline tube 19, the small gear 21 on the outer wall of the inner spline tube 19 drives the large gear 22 to rotate. The rotation of the large gear 22 drives the three-jaw chuck 23 to rotate. The rotation of the three-jaw chuck 23 drives the motor shaft to be tested to rotate.
[0035] The rotation of the inner spline tube 19 drives the spline shaft 16 to rotate, the rotation of the spline shaft 16 drives the drive gear 17 to rotate, the rotation of the drive gear 17 drives the end face gear 12 to rotate, the rotation of the end face gear 12 drives the guide tube 11 to rotate synchronously, and the rotation of the guide tube 10 drives the bottom lens 14 to rotate. During the rotation process, the oil and impurities on the surface of the lens 14 will be thrown off under the action of centrifugal force, thereby preventing the oil and impurities on the surface of the lens 14 from affecting the image quality of the CCD camera 5.
[0036] During the rotation of the guide tube 10, the incomplete gear 13 will also be driven to rotate. When the incomplete gear 13 rotates between two oppositely arranged long racks 18, it will drive the mounting plate 10 to make linear reciprocating motion in the slot 101, thereby driving the reflector 24 and the lens 14 to make scanning motion along the motor axis.
[0037] Compared with the prior art, the present invention provides a motor shaft straightening and inspection device for motor shaft production and processing, which uses a reflector 24 to project the image of the rotating motor shaft to be inspected onto a CCD camera 5, so that the CCD camera 5 can indirectly complete the image acquisition of the motor shaft, thereby preventing the lens of the CCD camera 5 from being contaminated by oil and impurities on the surface of the motor shaft.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
