Description

Technical Field

[0001] This utility model relates to the field of mechanical technology, specifically to a testing device for machining motor shafts. Background Technology

[0002] The working principle of an electric motor is that a magnetic field exerts a force on an electric current, causing the motor to rotate. During the production process of an electric motor, the surface of the motor shaft needs to be inspected. However, ordinary inspection agencies cannot completely detect the rotation of the shaft.

[0003] According to a public notice (Announcement No.: CN212748286U) of a testing device for machining motor shafts, the above application includes a first conveyor belt and a second conveyor belt, a buffer slide plate is connected between the first conveyor belt and the second conveyor belt, a bracket is fixedly connected to the front and rear sides of the upper opposite sides of the first conveyor belt and the second conveyor belt, a connecting plate is fixedly connected to the upper end of the bracket, and a lead screw is fixedly connected to the lower end of the connecting plate.

[0004] However, in actual use, the above-mentioned testing equipment relies on the spontaneous rotation of the motor shaft. This method is unpredictable and has the risk of starting failure or insufficient rotation. Its rotation speed and angular velocity fluctuate. If the rotation speed is too fast or there is slippage, some areas will not be fully scanned or tested, resulting in blind spots. This makes it difficult for the testing device to stably capture the surface features of the shaft, and it is easy to have false detections or missed detections. In view of this, we propose a testing equipment for motor shaft processing. Utility Model Content

[0005] The purpose of this invention is to provide a testing device for machining motor shafts, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a testing device for machining motor shafts, comprising a trapezoidal frame, a frame body fixedly connected to the side wall of the trapezoidal frame, a detection sensor fixedly connected to the inner bottom surface of the frame body, and a rotating assembly provided on the side wall of the frame body, the rotating assembly comprising:

[0007] The motor has a rotating shaft fixedly connected to its output end, a sun gear fixedly connected to the end face of the rotating shaft, and an internal gear ring fixedly connected to the side wall of the frame.

[0008] A planetary gear, wherein a rotating rod is fixedly connected to the side wall of the planetary gear, a magnet is fixedly connected to the end face of the rotating rod, a magnetic component is inserted into the end face of the rotating rod, a planet carrier is rotatably connected to the side wall of the rotating rod, an output shaft is fixedly connected to the side wall of the planet carrier, and a turntable is fixedly connected to the side wall of the output shaft.

[0009] Preferably, the motor is fixedly connected to the side wall of the frame, the sun gear meshes with the planetary gear, and the planetary gear meshes with the internal gear ring.

[0010] Preferably, the magnet is inserted into the magnetic component, and a rubber pad is fixedly connected to the end of the magnetic component away from the magnet. The outer wall of the rubber pad is provided with a strip groove, which increases the friction between the rubber pad and the shaft, thereby causing the magnetic component to rotate and drive the shaft to rotate.

[0011] Preferably, the number of turntables is set to several groups, and the several groups of turntables are equally spaced on the outer wall of the output shaft.

[0012] Preferably, the turntable has arc-shaped grooves on its side wall, and the number of arc-shaped grooves is set in several groups. The several groups of arc-shaped grooves are equally spaced on the side wall of the turntable. The number of arc-shaped grooves is equal to the number of magnetic components. The arc-shaped grooves are movably connected to the shafts, and the shafts are transferred one by one by rotating the turntable.

[0013] Preferably, a shuttle-shaped frame is fixedly connected to the inner wall of the frame, the shuttle-shaped frame is movably connected to the planetary frame, and the shuttle-shaped frame is movably connected to the magnetic component.

[0014] Preferably, a rotating shaft is inserted into the inner wall of the turntable, a clamping member is sleeved on the side wall of the rotating shaft, and a torsion spring is sleeved on the side wall of the rotating shaft, with both ends of the torsion spring fixedly connected to the side wall of the clamping member.

[0015] Compared with the prior art, this utility model provides a testing device for machining motor shafts, which has the following advantages:

[0016] 1. The inspection equipment for motor shaft processing uses a rotating assembly. The rotation of the turntable transports the shafts one by one, allowing them to pass uniformly under the inspection sensor. This facilitates continuous and accurate scanning of the entire shaft surface by the inspection sensor. The rotation of the planetary gear drives the magnetic components and rubber pads to rotate, which in turn drives the shaft to rotate. This ensures that the inspection system can cover the circumference of the shaft, eliminating blind spots and improving the completeness of surface defect identification. The outer wall of the rubber pad has a groove, which increases the friction between the rubber pad and the shaft, preventing relative slippage when the rubber pad drives the shaft to rotate, and ensuring that the shaft can rotate synchronously and stably.

[0017] 2. The testing equipment used for machining the motor shaft, through the set clamping parts, ensures that the shaft is located in the center of the arc groove. When the rubber pad is in contact with the shaft surface, it can fully contact the most effective position, avoiding eccentricity or insufficient contact. This ensures that the rotational driving force can be transmitted to the shaft to the maximum extent, preventing the shaft from rotating eccentrically or shaking, and ensuring uniform rotation.

Detailed Implementation

[0027] like Figures 1-8 As shown, this utility model provides a technical solution: a testing device for machining motor shafts, including a trapezoidal frame 1, a frame body 2 fixedly connected to the side wall of the trapezoidal frame 1, a detection sensor 3 fixedly connected to the inner bottom surface of the frame body 2, and a rotating assembly 4 provided on the side wall of the frame body 2. The rotating assembly 4 includes a motor 401, a sun gear 402, an internal gear ring 403, a planetary gear 404, a rotating rod 405, a magnet 406, a magnetic component 407, a rubber pad 408, a planetary carrier 409, an output shaft 410, a turntable 411, and a shuttle frame 412.

[0028] In one embodiment of this utility model, a motor 401 is fixedly connected to the side wall of the frame 2. A rotating shaft is fixedly connected to the output end of the motor 401. A sun gear 402 is fixedly connected to the end face of the rotating shaft. An internal gear ring 403 is fixedly connected to the side wall of the frame 2. The sun gear 402 meshes with a planetary gear 404, and the planetary gear 404 meshes with the internal gear ring 403. A rotating rod 405 is fixedly connected to the side wall of the planetary gear 404. A magnet 406 is fixedly connected to the end face of the rotating rod 405. A magnetic component 407 is inserted into the side of the rotating rod 405. A planetary carrier 409 is rotatably connected to the side wall of the planetary carrier 409. An output shaft 410 is fixedly connected to the side wall of the output shaft 410. A turntable 411 is fixedly connected to the side wall of the output shaft 410. A magnet 406 is inserted into the magnetic component 407. A rubber pad 408 is fixedly connected to the end of the magnetic component 407 away from the magnet 406. A strip groove is formed on the outer wall of the rubber pad 408. The strip groove increases the friction between the rubber pad 408 and the shaft, thereby causing the magnetic component 407 to rotate and drive the shaft to rotate.

[0029] The number of turntables 411 is set in several groups, and the several groups of turntables 411 are equally spaced on the outer wall of the output shaft 410. The side wall of the turntable 411 is provided with arc-shaped grooves, and the number of arc-shaped grooves is set in several groups, and the several groups of arc-shaped grooves are equally spaced on the side wall of the turntable 411. The number of arc-shaped grooves is equal to the number of magnetic components 407. The arc-shaped grooves are movably connected to the shaft. The shaft is transferred one by one by rotating the turntable 411. The inner wall of the frame 2 is fixedly connected with a shuttle-shaped frame 412, which is movably connected to the planetary frame 409 and the magnetic components 407.

[0030] The shaft slides along the inclined surface of the trapezoidal frame 1. The motor 401 drives the rotating shaft and the sun gear 402 to rotate, which in turn drives the planetary gear 404 to rotate. The planetary gear 404 revolves around the sun gear 402 while simultaneously rotating on its own axis. The revolution of the planetary gear 404 drives the planetary carrier 409 and the output shaft 410 to rotate, which in turn drives the turntable 411 to rotate. Through the rotation of the turntable 411, the shafts are transported one by one, so that the shafts pass under the detection sensor 3 at a uniform speed, which is conducive to the detection sensor 3 continuously and accurately scanning the entire surface of the shaft.

[0031] When the magnetic component 407 rotates to contact the shuttle frame 412, the shuttle frame 412 pushes the magnetic component 407 to move away from the planetary frame 409, thereby causing the rubber pad 408 to abut against one end of the shaft. At this time, the other end of the shaft abuts against the inner wall of the frame 2. The rotation of the planetary gear 404 drives the magnetic component 407 and the rubber pad 408 to rotate, thereby driving the shaft to rotate. This ensures that the detection system can cover the circumferential surface of the shaft, eliminates blind spots in detection, and improves the completeness of surface defect identification. The outer wall of the rubber pad 408 is provided with a strip groove. The strip groove increases the friction between the rubber pad 408 and the shaft, preventing the rubber pad 408 from slipping relative to the shaft when it drives the shaft to rotate, and ensuring that the shaft can rotate synchronously and stably.

[0032] In addition, a rotating shaft 5 is inserted into the inner wall of the turntable 411, a clamping member 6 is sleeved on the side wall of the rotating shaft 5, and a torsion spring 7 is sleeved on the side wall of the rotating shaft 5. The two ends of the torsion spring 7 are fixedly connected to the side wall of the clamping member 6. The torsion spring 7 clamps the shaft through the elastic deformation of the clamping member 6, ensuring that the shaft is located in the center of the arc groove. When the rubber pad 408 is in contact with the most effective position of the shaft surface, it avoids eccentricity or insufficient contact, thereby ensuring that the rotation driving force can be transmitted to the shaft to the maximum extent, preventing the shaft from rotating eccentrically or shaking, ensuring the uniformity of rotation, making it rotate stably and synchronously, and improving the concentricity and stability of the shaft rotation.

[0033] In this invention, during use, the motor 401 drives the rotating shaft and the sun gear 402 to rotate, which in turn drives the planetary gear 404 to rotate. The planetary gear 404 revolves around the sun gear 402 while simultaneously rotating on its own axis. The revolution of the planetary gear 404 drives the planet carrier 409 and the output shaft 410 to rotate, which in turn drives the turntable 411 to rotate. Through the rotation of the turntable 411, each transport shaft passes at a constant speed below the detection sensor 3. When the magnetic component 407 rotates to contact the shuttle frame 412, the shuttle frame 412... 12. The magnetic component 407 is pushed to move away from the planetary carrier 409, thereby causing the rubber pad 408 to abut against one end of the shaft. At this time, the other end of the shaft abuts against the inner wall of the carrier 2. The rotation of the planetary gear 404 drives the magnetic component 407 and the rubber pad 408 to rotate, thereby driving the shaft to rotate. This ensures that the detection system can cover the circumferential surface of the shaft, eliminates detection blind spots, and improves the integrity of surface defect identification. The strip groove increases the friction between the rubber pad 408 and the shaft, preventing the rubber pad 408 from slipping relative to the shaft when it rotates.

[0034] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
