[0002] A motor shaft is a rotating shaft in an electric motor or generator that connects the motor to a reducer (if applicable). Its core functions are to transmit torque, support rotating components, and convert electrical energy into mechanical energy. Its material must possess high strength (such as alloy steel or stainless steel) to withstand loads, while also requiring high precision and wear resistance.

[0003] During the machining process, the motor shaft requires surface polishing to improve surface smoothness, reduce frictional resistance, and enhance its mechanical properties and service life. Polishing involves placing both ends on support rollers. However, when the length and cross-sectional diameter of the motor shaft change, the existing support device's two pairs of support rollers cannot be adjusted in position, limiting its applicability.

[0004] Therefore, it is desirable to provide a limiting device for polishing the surface of a motor shaft, in order to solve the above-mentioned technical problems. Utility Model Content

[0032] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0033] Example

[0034] like Figure 2 As shown in the figure, the limiting device for polishing the surface of a motor shaft provided in this embodiment includes a support frame 1, a vertical adjustment mechanism and a horizontal adjustment mechanism.

[0035] The vertical adjustment mechanism includes a vertical moving seat 2 and a driving device; the vertical moving seat 2 is located directly above the support frame 1 and always remains horizontal; the driving device is mounted on the support frame 1 and is used to drive the vertical moving seat 2 to move in the vertical direction.

[0036] In this embodiment, a guide post 3 is fixed at the bottom of the vertical moving seat 2. The guide post 3 is vertically arranged and slides through the top of the support frame 1. This arrangement can effectively ensure the stability and directional accuracy of the vertical moving seat 2 in the vertical direction.

[0037] In this embodiment, as Figure 1 As shown, the driving device includes a first lead screw 4 and a first nut 5; a support plate 6 is provided directly below the center of the lower surface of the support frame 1, and the first nut 5 is horizontally rotatably mounted on the support plate 6; the first lead screw 4 is threadedly connected to the first nut 5 and slides through the support plate 6 and the top of the support frame 1, and the upper end of the first lead screw 4 is connected to the bottom of the vertical moving seat 2; with this configuration, by rotating the first nut 5, the first lead screw 4 moves in the vertical direction, and finally realizes the vertical moving seat 2 to move in the vertical direction, adapting to motor shafts with different cross-sectional diameters, facilitating polishing by external polishing equipment.

[0038] Furthermore, in this embodiment, the side of the first nut 5 is provided with a plurality of handles 7 in a circular array to facilitate the user to rotate the first nut 5.

[0039] Alternatively, the drive device can also be a screw jack (not shown in the figure).

[0040] The horizontal adjustment mechanism includes a second lead screw 8 and a pair of horizontal moving modules; the vertical moving seat 2 is provided with a mounting groove 9, and the second lead screw 8 is horizontally rotatably disposed in the mounting groove 9; the vertical moving seat 2 is also provided with a motor 10 for driving the second lead screw 8 to rotate; two second nuts 11 are threaded onto the second lead screw 8, the two second nuts 11 are symmetrically arranged, and the internal threads of the two second nuts 11 are in opposite directions; the pair of horizontal moving modules includes a mounting base 12 and a pair of support wheels 13; the two mounting bases 12 are respectively fixed on the corresponding second nuts 11. In this embodiment, the mounting bases 12 are detachably fixed on the corresponding second nuts 11 by bolts, which facilitates subsequent replacement of the mounting bases 12 and maintenance; the pair of support wheels 13 are disposed on the inner side of the mounting base 12.

[0041] In this embodiment, the top of the mounting base 12 is recessed downward to form a clearance area 14, which facilitates the end of the placed motor shaft to pass through and more stably supports the motor shaft to be polished.

[0042] In this embodiment, the vertical moving seat 2 is provided with sliding grooves 15 on both sides of the second lead screw 8; the mounting seat 12 is slidably disposed on the two sliding grooves 15, and the mounting seat 12 is provided with a set screw 16 at the position opposite to the sliding groove 15. After the mounting seat 12 moves to the appropriate position, the position of the mounting seat 12 can be effectively fixed by the set screw 16, so as to more stably support the motor shaft.

[0043] like Figure 3 As shown, when it is necessary to polish the motor shaft 17, the motor 10 is started according to the length of the motor shaft 17, so that the second lead screw 8 rotates, thereby changing the distance between the two mounting seats 12 to fit the motor shaft 17. Then, the two ends of the motor shaft 17 are placed on the two pairs of support wheels 13. Then, the first nut 5 is rotated so that the vertical moving seat 2 rises to a suitable height, and the external polishing equipment is started to polish the motor shaft 17.
