This device features a compact overall structure and an automated polishing process, eliminating the need for manual polishing of the motor shaft, saving labor and improving polishing efficiency. The use of hydraulic lifting columns effectively polishes the motor shaft comprehensively, improving polishing quality. However, the device lacks an intercepting mechanism, allowing burrs to scatter in the surrounding environment, increasing the cleaning area and potentially causing harm to the operator.

[0021] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0022] like Figures 1 to 3 As shown, an automatic polishing device for a motor shaft includes a processing table 1 and a transparent visual panel 3. A protective cover 2 is installed on the top of the processing table 1, and an interception assembly 7 is installed in the middle of the top rear of the processing table 1. The interception assembly 7 includes a second cylinder 701, a rack 702, a gear 1 703, a gear 2 704, a transmission shaft 1 705, a pulley 1 706, a belt 707, a pulley 2 708, a transmission shaft 2 709, a side plate 710 and a support base 711. The top of the second cylinder 701 is connected to the rack 702, and the two sides of the rack 702 are respectively provided with a gear 1 703 and a gear 2 704. A transmission shaft 1 705 is passed through the middle of gear 1 703 and gear 2 704, a pulley 1 706 is sleeved on the outside of the transmission shaft 1 705, and the outside of the pulley 1 706 is connected to the pulley 2 708 through a belt 707, a transmission shaft 2 709 is passed through the middle of the pulley 2 708, and the outside of the transmission shaft 2 709 is connected to the side plate 710, support seats 711 are provided on both sides of the front and rear surfaces of the processing table 1, a transparent visual panel 3 is provided through the opening on the surface of the protective cover 2, a cylinder 1 4 is installed on the lower inner side of the protective cover 2, and a clamping member 5 is provided at the end of the cylinder 1 4.

[0023] The specific operation is as follows: the cylinder 2 701 retracts to drive the rack 702 to move downward, and the rack 702 drives the gear 1 703 and the gear 2 704 to rotate, and the friction between the belt 707 and the pulley 1 706 and the pulley 2 708 is used to transmit power to make the drive shaft 2 709 and the side plate 710 rotate synchronously with the drive shaft 1 705. Since the rotation directions of the gear 1 703 and the gear 2 704 are opposite, the two side plates 710 are rotated in the clockwise and counterclockwise directions respectively until the side plates 710 are tightly attached to the two sides of the protective cover 2, so that the polishing work is carried out in a sealed space to avoid burrs flying and causing harm to the operator.

[0024] like Figure 3 As shown, an adjustment component 6 is installed at the top middle end of the protective cover 2, and the adjustment component 6 includes a drive motor 601 and a drive rod 602, the output end of the drive motor 601 passes through the top of the protective cover 2 and is connected to the drive rod 602, the adjustment component 6 also includes a rotating frame 603, an electric telescopic rod 604 and a lifting plate 605, and the bottom of the drive rod 602 is installed with a rotating frame 603, the inner top of the rotating frame 603 is provided with an electric telescopic rod 604, and the outer end of the electric telescopic rod 604 is connected to the lifting plate 605, the adjustment component 6 also includes a swing arm 1 606, a mounting plate 607 and a swing arm 2 608, and both sides of the lifting plate 605 are connected to the swing arm 1 606 through a rotating shaft, and the other end of the swing arm 1 606 is connected to The mounting plate 607 is provided, and a swing arm 2 608 is connected to the surface of the mounting plate 607 via a rotating shaft. The adjustment component 6 also includes a swing arm 3 609 and a polishing roller 610, and a swing arm 3 609 is connected to the surface of the mounting plate 607 via a rotating shaft. A polishing roller 610 is provided at the bottom of the mounting plate 607. The swing arm 2 608 and the swing arm 3 609 are parallel to each other, and the end of the swing arm 2 608 away from the mounting plate 607 is rotatably connected to the rotating frame 603, and the end of the swing arm 3 609 away from the mounting plate 607 is rotatably connected to the rotating frame 603. The gear 1 703 and the gear 2 704 rotate in opposite directions, and two transmission shafts 1 705 and 709 are provided respectively, and the transmission shaft 2 709 is rotatably connected to the support seat 711.

[0025] The specific operation is as follows: the electric telescopic rod 604 retracts to drive the lifting plate 605 to rise. During the rising process of the lifting plate 605, the swing arm 1 606 will rotate, and the swing arm 2 608 and the swing arm 3 609 provide support force to move the mounting plate 607 toward the direction close to the rotating frame 603, thereby adjusting the distance between the polishing rollers 610, improving the adaptability of the device to motor shafts of different diameters, and making the device highly versatile.

[0026] In summary, when the motor shaft automatic polishing device is used, the motor shaft is first placed between the clamping members 5. Since the clamping member 5 is provided with a notch on one side close to the vertical central axis of the processing table 1, the notch is an isosceles trapezoidal structure when viewed from above, so that the control cylinder 1 4 can be extended to clamp the motor shaft using the clamping member 5;

[0027] Then, the control cylinder 2 701 is retracted to drive the rack 702 to move downward, and the rack 702 drives the gear 1 703 and the gear 2 704 to rotate the two transmission shafts 1 705. The friction between the belt 707 and the pulley 1 706 and the pulley 2 708 transmits power to make the transmission shaft 2 709 rotate synchronously with the transmission shaft 1 705. Since the rotation directions of the gear 1 703 and the gear 2 704 are opposite, the two side plates 710 are rotated in the clockwise and counterclockwise directions respectively until the side plates 710 are tightly attached to the two sides of the protective cover 2.

[0028] Then, the electric telescopic rod 604 is controlled to retract and drive the lifting plate 605 to rise. The lifting plate 605 drives the swing arm 1 606 to rotate, causing the mounting plates 607 to move closer to each other. The mounting plates 607 are kept vertical based on the support force provided by the swing arm 2 608 and the swing arm 3 609. When the polishing roller 610 is in contact with the outer surface of the motor shaft, the drive motor 601 is started to drive the drive rod 602 and the rotating frame 603 to rotate, and the motor shaft is polished by the polishing roller 610. Since the side plate 710 and the protective cover 2 form a sealed space, the polishing work is carried out in the sealed space, so that burrs can be intercepted, which not only reduces the cleaning range but also prevents burrs from splashing and causing harm to the operator.

[0029] After polishing is completed, the control cylinder 2 701 extends to drive the rack 702 to move upward, and the rack 702 drives the gear 1 703 and the gear 2 704 to rotate the two transmission shafts 1 705. The friction between the belt 707 and the pulley 1 706 and the pulley 2 708 is used to transmit power to make the transmission shaft 2 709 rotate synchronously with the transmission shaft 1 705. Since the rotation directions of the gear 1 703 and the gear 2 704 are opposite, the two side plates 710 rotate counterclockwise and clockwise respectively, that is, they are unfolded at the same time, which makes it easier to remove the motor shaft.

[0030] The embodiments of the present invention are provided for purposes of illustration and description and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for specific applications.
