[0001] The utility model relates to the technical field of motor shaft rust removal, in particular to a motor shaft rust removal device. Background Art

[0002] At present, during the use of a motor, rust will occur on the motor shaft, and the staff needs to renovate the motor shaft. In the prior art, the rust removal of the motor shaft is mostly carried out by manually holding a grinding machine to grind and remove the rust on the motor shaft. Due to the poor effect of manual rust removal and large limitations, after long-term work, due to the fatigue of the staff, the grinding accuracy is likely to become low, and then the motor shaft is damaged. Therefore, a machine is used to replace manual labor to remove rust from the motor shaft. However, before the machine removes rust from the motor shaft, it is necessary to adjust the axis of the motor shaft to be consistent with the axis of the machine grinding assembly, which is difficult to construct and results in low efficiency of motor shaft rust removal. Summary of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0019] Embodiment 1: Refer to Figures 1-4, a motor shaft rust removal device, including a base 1. On one side of the top of the base 1, a hydraulic telescopic component 2 is arranged. On the hydraulic telescopic component 2, a connecting plate 3 is arranged. On both sides of the connecting plate 3, connecting blocks 4 are installed. On both of the two connecting blocks 4, moving bars 5 are placed. The two connecting blocks 4 are both inclined. The two moving bars 5 both penetrate through the two connecting blocks 4. On the other side of the top of the base 1, a grinding component 6 is arranged. In the middle of the top of the base 1, a placement plate 7 is arranged. The inclination angles of the two moving bars 5 both face the placement plate 7. A moving mechanism is arranged between the placement plate 7 and the base 1. The moving mechanism includes a first groove 8 opened on the top of the base 1. The placement plate 7 is placed in the first groove 8. On one side of the placement plate 7, a fixed block 9 is arranged. On the first groove 8, a second groove 10 is opened. One end of the fixed block 9 is slidably arranged in the second groove 10. At the first groove 8, a threaded rod 11 is installed through a bearing. The threaded rod 11 threadedly penetrates through the placement plate 7.

[0020] Combined with the attached Figures 3-4 , on one side of the set base 1, a servo motor 14 is arranged. The output shaft of the servo motor 14 is connected to one end of the threaded rod 11; the grinding head of the set grinding component 7 is sleeve-shaped, and an electric telescopic rod is used to drive the grinding component 6 to move.

[0021] After placing the motor to be polished on the placement plate 7, align the motor shaft with the grinding component 6, and then start the hydraulic telescopic component 2. The hydraulic telescopic component 2 drives the connecting plate 3 to move towards the motor. During the movement of the connecting plate 3, the moving bars 5 on both sides of the connecting plate 3 will first contact the shell of the motor. During the process of the two moving bars 5 contacting the shell of the motor, one of the moving bars 5 will contact the shell of the motor first, so as to know that the axis of the motor shaft is offset from the axis of the grinding component 6. At this time, start the servo motor 14. The output shaft of the servo motor 14 will drive the threaded rod 11 to rotate. During the rotation of the threaded rod 11, it will drive the placement plate 7 to move in the first groove 8, so that the motor on the placement plate 7 is adjusted relative to the grinding component 6 together. When the hydraulic telescopic component 2 drives the connecting plate 3 to press the motor, after the two moving bars 5 move the same distance on the two connecting blocks 4, after the connecting plate 3 presses the motor, the axis of the motor shaft will be collinear with the axis of the grinding component 6. Thus, after the motor is fixed, the difficulty of making the axis of the motor shaft collinear with the axis of the grinding component 6 is reduced, and the polishing efficiency of the motor shaft is improved.

[0022] Embodiment 2: Optimized on the basis of Embodiment 1, refer to Figures 1-4 , wear-resistant coatings are arranged on both the fixed block 9 and the second groove 10. The grinding head of the grinding component 6 is located in the first groove 8, and there is a gap between the bottom of the placement plate 7 and the bottom of the first groove 8.

[0023] The provided wear-resistant coating is formed by nitriding treatment, thereby improving the mechanical properties of the base 1 at the fixing block 9 and the second groove 10, making the base 1 at the fixing block 9 and the second groove 10 more wear-resistant; there is a gap between the placement plate 7 and the bottom of the first groove 8, and the grinding head of the grinding assembly 6 is located in the first groove 8. Thus, during the process of the grinding assembly 6 grinding the motor shaft, the generated waste chips and coolant will flow back into the first groove 8, so that during the grinding process of the motor shaft, it is not easy to generate sewage near the device, improving the safety of the operator.

[0024] Embodiment 3: Optimized on the basis of Embodiment 1, referring to Figures 1-4 , scale grooves 12 are provided on both of the two moving bars 5, and a pressing block 13 is provided at the bottom of the connecting plate 3.

[0025] By providing scale grooves 12 on the two moving bars 5, it is easier to know the length of the movement of the two moving bars 5 on the two connecting blocks 4, thereby making it easier to adjust the position of the placement plate 7 in Embodiment 1; the provided pressing block 13 makes the motor less likely to move when it is fixed, making the fixation of the motor more stable.

[0026] The above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
