Description

Technical Field

[0001] This utility model relates to the field of polishing equipment technology, specifically to an auxiliary device for polishing the side surface of a motor housing. Background Technology

[0002] Small and medium-sized motor housings are typically manufactured using die casting. During the high-pressure casting process, a small number of motor housings develop randomly distributed flash defects on their side surfaces due to factors such as mold parting line gaps, overflow from venting channels, or fluctuations in process parameters. Because these defective parts are few in number and their locations are irregular, fully automated grinding equipment is not suitable (as the equipment itself and its maintenance costs are high). Currently, the removal of these irregular flash defects mainly relies on manual operation: operators must hold the motor housing by hand and align the burr-covered areas with a high-speed rotating grinding wheel or grinder for localized grinding.

[0003] However, this method has significant drawbacks: First, the operator's hands are too close to the rotating grinding tool, posing a safety hazard of mechanical entanglement or flying debris; second, the motor housing has a certain weight, and the position of the flash is highly random. When manually adjusting the angle, it is necessary to rotate the motor housing by hand. Holding it for a long time can easily lead to muscle fatigue for the operator, resulting in high labor intensity and low work efficiency. Utility Model Content

By having a person hold the handle, the motor housing on the fixed component can be adjusted vertically, horizontally, and circumferentially through the cooperation of a vertical moving component, a horizontal telescopic component, and a rotating component. The hands are kept away from the polishing mechanism, ensuring work safety. The adjustment range is small, reducing the labor intensity of personnel and improving work efficiency and quality.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary device for grinding the side surface of a motor housing, comprising a base plate, a vertical rod, a vertical moving component, a horizontal telescopic component, a rotating component, a fixing component, a handle, a grinding mechanism, and a support component.

The vertical moving component is mounted on the vertical rod, and its moving end can move vertically and rotate on the vertical rod. One end of the horizontal telescopic component is fixedly connected to the moving end of the vertical moving component, and the other end of the horizontal telescopic component is fixedly mounted on... The device includes a mounting plate, and a horizontal telescopic component that allows the mounting plate to move horizontally.

The grinding mechanism 7 is installed at the upper end of the support component, and the grinding end of the grinding mechanism 7 is located within the adjustment range of the vertical moving component, the horizontal telescopic component, and the rotating component. The vertical moving component includes a pair of first limiting plates 13 and a first sleeve 15. The first limiting plates 13 are fixedly installed on the upper part of the upright 14, and the distance between the pair of first limiting plates 13 is greater than that of the motor. The shell 9 has its own height. The first sleeve 15 is movably fitted onto the upright 14 and located between a pair of first limiting plates 13. The first sleeve 15 can move and rotate vertically on the upright. The horizontal telescopic assembly adopts a telescopic rod 12. One end of the telescopic rod 12 is fixedly connected to the side surface of the first sleeve 15 through a mounting base 16, and the other end of the telescopic rod 12 is fixedly connected to the side wall of the mounting plate 18. The rotating assembly includes a pair of second limiting plates 8, a second sleeve 17, and a rotating column 11. The side surface of the second sleeve 17 is fixedly connected to the side wall of the mounting plate 18. The rotating column 11 movably passes through the second sleeve 17. A pair of second limiting plates 8 are respectively arranged at the upper and lower ends of the rotating column 11. The diameter of the second limiting plates 8 is... The inner diameter of the rotating column 11 is larger than that of the second sleeve 17, and the rotating column 11 can rotate inside the second sleeve 17. The center position of the lower bottom surface of the second limiting plate 8 at the lower end of the rotating column 11 is fixedly connected to the handle 21. The fixing component 10 is set on the upper surface of the second limiting plate 8 at the upper end of the rotating column 11. The support component includes a support cylinder 1, a support plate 5 and a pair of bolts 3. The lower end of the support cylinder 1 is fixedly connected to the upper surface of the base plate 2. The support plate 5 is inserted into the support cylinder 1 from top to bottom. A plurality of adjustment holes 4 are evenly arranged on the support plate 5. The support plate 5 and the support cylinder 1 are fixed by a pair of bolts 3 passing through the support cylinder 1 and the adjustment holes 4. A support seat 6 is horizontally arranged at the upper end of the support plate 5. The grinding mechanism 7 is set on the support seat 6.The fixing component 10 is fixed by a motor drive. A switch 20 is provided on the handle 21, which controls the fixing component 10 to be fixed. A rubber sleeve 19 is provided on the handle 21.

[0019] Its detailed connection methods are well-known technologies in this field. The following mainly introduces the working principle and process, as follows:

[0020] According to the instruction manual Figure 1 It is understood that during operation, the operator vertically places the motor housing 9 onto the fixing component 10 and secures its inner wall by pressing against it using the fixing component 10. The fixing component 10 employs existing technology. The grinding mechanism 7 on the support component is also existing technology. Since the moving end of the vertical moving component can move vertically and rotate on the upright 14, the horizontal telescopic component can drive the mounting plate 18 to move horizontally, and the rotating end of the rotating component can rotate around the vertical axis, when the operator holds the handle 21 and rotates it, the rotating component can drive the fixing component 10 and the motor housing 9 to rotate. When the operator pushes the handle 21 horizontally, the motor housing 9 can be moved horizontally by the rotation of the vertical moving component on the upright 14 and the extension and retraction of the horizontal telescopic component. When the operator pushes the handle 21 vertically, the motor housing 9 can be moved vertically by the vertical movement of the vertical moving component on the upright 14. The coordination of the vertical moving component, horizontal telescopic component, and rotating component allows for adjustment of various positions on the side surface of the motor housing 9, enabling it to work with the grinding mechanism 7 to grind the burrs on the side surface. Personnel keep their hands away from the grinding mechanism 7, ensuring work safety. The initial position of the motor housing 9 after installation on the fixed component 10 is achieved. Grinding can be performed at various positions within the adjustment range of the vertical moving component, horizontal telescopic component, and rotating component. This eliminates the need for personnel to raise and lower their hands extensively to adjust the position, and the adjustment range is much smaller compared to completely manual operation. Furthermore, the support provided by the vertical moving component, horizontal telescopic component, and rotating component during adjustment reduces labor intensity and improves work efficiency and quality.

[0021] The vertical moving component includes a pair of first limiting plates 13 and a first sleeve 15. The first limiting plates 13 are fixedly installed on the upper part of the upright 14, and the distance between the pair of first limiting plates 13 is greater than the height of the motor housing 9 itself, ensuring that the adjustment range can cover all positions in the height direction of the side surface of the motor housing 9. The first sleeve 15 is movably sleeved on the upright 14 and located between the pair of first limiting plates 13. The first sleeve 15 can move and rotate vertically on the upright. The structure is simple, easy to disassemble and install, and has low maintenance costs.

[0022] The horizontal telescopic component uses a telescopic rod 12. One end of the telescopic rod 12 is fixedly connected to the side surface of the first sleeve 15 via a mounting base 16. The mounting base 16 is existing technology and enhances the stability of the telescopic rod 12. The other end of the telescopic rod 12 is fixedly connected to the side wall of the mounting plate 18. Here, it is necessary to consider the load-bearing capacity of the telescopic rod 12 in the non-axial direction to ensure support for the rotating component, the fixed component 10, and the motor housing 9. Of course, it is also possible to set multiple telescopic rods 12 in the same direction to increase its vertical load-bearing capacity, or to use a slide rail slider with a stronger vertical load-bearing capacity. Those skilled in the art can understand this.

[0023] The rotating assembly includes a pair of second limiting plates 8, a second sleeve 17, and a rotating column 11. The side surface of the second sleeve 17 is fixedly connected to the side wall of the mounting plate 18. The rotating column 11 is movably inserted through the second sleeve 17. The pair of second limiting plates 8 are respectively set at the upper and lower ends of the rotating column 11. The diameter of the second limiting plate 8 is larger than the inner diameter of the second sleeve 17 to ensure the vertical stability of the rotating column 11 and to allow the rotating column 11 to rotate within the second sleeve 17. The center position of the bottom surface of the second limiting plate 8 at the lower end of the rotating column 11 is fixedly connected to the handle 21. The fixing assembly 10 is set on the upper surface of the second limiting plate 8 at the upper end of the rotating column 11. The entire rotating assembly has a simple structure, is easy to disassemble and install, and has low maintenance costs.

[0024] The support assembly includes a support cylinder 1, a support plate 5, and a pair of bolts 3. The lower end of the support cylinder 1 is fixedly connected to the upper surface of the base plate 2. The support plate 5 is inserted into the support cylinder 1 from top to bottom. Multiple adjustment holes 4 are evenly arranged on the support plate 5. The support plate 5 and the support cylinder 1 are fixed by a pair of bolts 3 passing through the support cylinder 1 and the adjustment holes 4. A support seat 6 is horizontally arranged at the upper end of the support plate 5. The grinding mechanism 7 is arranged on the support seat 6. This design achieves the purpose of adjusting the vertical height of the grinding mechanism 7. According to the model of the motor housing 9, that is, motor housings 9 of different heights, the vertical position of the grinding mechanism 7 can be adjusted to be closer to the motor housing 9, so that the range of adjustment of the motor housing 9 by the personnel is smaller and more labor-saving.

[0025] The fixing component 10 is fixed by motor drive. A switch 20 is provided on the handle 21. The switch 20 controls the fixing component 10 to fix it, which improves the degree of automation and makes it more convenient to fix the motor housing 9.

[0026] The handle 21 is equipped with a rubber sleeve 19 to increase the comfort of the person holding the handle 21.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
