Description

Technical Field

[0001] This utility model relates to the field of rust removal technology for motor shafts, and in particular to a rust removal device for motor shafts. Background Technology

[0002] An electric motor is an electromagnetic device that converts or transmits electrical energy based on the law of electromagnetic induction. During long-term use, the motor shaft needs to be refurbished. Due to long-term use, rust will appear on the motor shaft. After long-term use, the motor shaft needs to be derusted. Therefore, it is necessary to design a motor shaft derusting device for electric motors.

[0003] Currently, most rust removal of motor shafts is done manually by hand-held grinders. However, since motor shafts are mostly cylindrical, grinding is very inconvenient. In addition, workers need to hold the grinder continuously, which increases the labor intensity of workers, affects the rust removal effect, and reduces the quality of rust removal of motor shafts. Utility Model Content

[0004] The purpose of this utility model is to provide a rust removal device for motor shafts, which facilitates the improvement of the rust removal quality of motor shafts in the later stage, and eliminates the need for operators to hold rust removal and grinding machines, effectively reducing the labor intensity of workers in the later stage and improving the efficiency and convenience of subsequent grinding.

[0005] To achieve the above objectives, a rust removal device for motor shafts is provided, comprising: a U-shaped mounting base, a motor mounted on the top of one side of the U-shaped mounting base, a rotating rod extending to the inner side of the U-shaped mounting base from the output end of the motor, guide rails mounted on the side of the rotating rod away from the motor and the top of the U-shaped mounting base on the side away from the motor, arc-shaped fixing plates extending to the outside slidably mounted on the top and bottom of the two sets of guide rails, and the two sets of arc-shaped fixing plates on the same side cooperating with each other, a bidirectional screw rotatably mounted inside the two sets of guide rails, and the bidirectional screw threads penetrating into the inside of the arc-shaped fixing plates and extending to the top of the outer side of the guide rails, the inner sides of the four sets of arc-shaped fixing plates jointly clamping the motor shaft, a drive assembly provided on the outer side of the rotating rod near the guide rail, and a grinding assembly provided at the middle position of the bottom of the U-shaped mounting base near the motor shaft.

[0006] According to the aforementioned motor shaft rust removal equipment for motors, the drive assembly includes a second bevel gear, a first bevel gear, an incomplete gear, and a first rotating rod. The second bevel gear is installed on the outside of the second rotating rod near the guide rail. The first rotating rod is rotatably installed in the middle position of the bottom of the U-shaped mounting base near the second rotating rod. An incomplete gear is installed on the bottom of the outer side of the first rotating rod, and the first bevel gear is installed on the top of the first rotating rod, and the first bevel gear meshes with the second bevel gear.

[0007] According to the aforementioned rust removal equipment for motor shafts, the grinding assembly includes a connecting rod, a sliding groove, a slider, a spring, an internally threaded sleeve, a threaded rod, an arc-shaped rust removal plate, and toothed blocks. The sliding groove is located at the middle position of the bottom of the U-shaped mounting base near the motor shaft. A slider is slidably mounted inside the sliding groove. A spring connected to the slider is provided on one side inside the sliding groove. An internally threaded sleeve is installed on the top of the slider. A threaded rod extending to the outside of the internally threaded sleeve is threaded inside the internally threaded sleeve. An arc-shaped rust removal plate is rotatably mounted on the top of the threaded rod, and the arc-shaped rust removal plate is in contact with the outside of the motor shaft. A connecting rod is installed on one end of the back of the internally threaded sleeve. Toothed blocks are evenly provided on one end of the front of the connecting rod near the incomplete gear, and the toothed blocks mesh with the incomplete gear.

[0008] According to the aforementioned motor shaft rust removal equipment, the two sets of arc-shaped fixing plates on the same side each have internal threaded holes on opposite sides, and the internal threaded holes cooperate with the bidirectional screw.

[0009] According to the aforementioned motor shaft rust removal equipment, the motor is provided with an external mounting chamber, and the inner side of the mounting chamber is provided with protective cotton.

[0010] According to the aforementioned motor shaft rust removal equipment for motors, a rotating shaft is provided at the middle position of the top of the U-shaped mounting base away from the motor, and the rotating shaft is connected to another set of guide rails.

[0011] The above solution has the following advantages: Through the structural design of the bidirectional screw, arc-shaped fixing plate and guide rail, the motor shaft can be easily fixed and limited without the need for the operator to manually limit it. Compared with manual gripping, this structural design has better stability and is more robust. At the same time, through the design and cooperation of the motor and the rotating rod, the motor shaft can also be rotated, which facilitates the subsequent rotation, grinding and rust removal of the motor shaft.

[0012] Simultaneously, the rotation of the motor shaft can be achieved through the rotating rod two and the motor. In conjunction with the structural design of bevel gear two, bevel gear one, rotating rod one, rotating rod two, tooth block and connecting rod, it can also drive the slider, internal threaded sleeve, threaded rod and arc-shaped rust removal plate to move inside the slide groove to compress the spring. And by moving the arc-shaped rust removal plate and then coordinating with the rotation of the motor shaft, grinding and rust removal work can be carried out at different positions on the outside of the motor shaft. Moreover, due to the structural design of this component, there is no need for the operator to hold the grinder, which effectively reduces the labor intensity of workers in the later stage and increases the convenience and practicality of the equipment in the later stage of use.

[0021] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the description of the textual part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0022] Reference Figure 1-4This utility model discloses a rust removal device for motor shafts, comprising: a U-shaped mounting base 1; a motor 13 is mounted on the top of one side of the U-shaped mounting base 1; a rotating rod 12 extending into the inside of the U-shaped mounting base 1 is provided at the output end of the motor 13; guide rails 16 are mounted on the top of both the rotating rod 12 away from the motor 13 and the side of the U-shaped mounting base 1 away from the motor 13; arc-shaped fixing plates 15 extending outward are slidably provided at the top and bottom of the two sets of guide rails 16, and the two sets of arc-shaped fixing plates 15 on the same side cooperate with each other; the interior of the two sets of guide rails 16... All are rotatably mounted with bidirectional screws 14, and the threads of the bidirectional screws 14 penetrate into the interior of the arc-shaped fixing plate 15 and extend to the top of the outer side of the guide rail 16. The inner sides of the four sets of arc-shaped fixing plates 15 together clamp the motor shaft 11. The outer side of the rotating rod 12 near the guide rail 16 is provided with a drive assembly. The bottom of the U-shaped mounting base 1 is provided with a grinding assembly at the middle position near the motor shaft 11. This facilitates the improvement of the rust removal quality of the motor shaft in the later stage, and eliminates the need for operators to hold a rust removal and grinding machine, effectively reducing the labor intensity of workers in the later stage and improving the efficiency and convenience of the later grinding.

[0023] The drive assembly includes a second bevel gear 18, a first bevel gear 17, an incomplete gear 2, and a first rotating rod 3. The second bevel gear 18 is installed on the outside of the second rotating rod 12 near the guide rail 16. The first rotating rod 3 is rotatably installed in the middle position of the bottom of the U-shaped mounting base 1 near the second rotating rod 12. The incomplete gear 2 is installed on the bottom of the outer side of the first rotating rod 3, and the first bevel gear 17 is installed on the top of the first rotating rod 3. The first bevel gear 17 meshes with the second bevel gear 18, so that when the motor 13 drives the second rotating rod 12 to rotate, the grinding assembly can be moved through the drive assembly, so that one drive component can perform two steps, reducing the wear and tear of parts installation.

[0024] The grinding assembly includes a connecting rod 4, a slide groove 5, a slider 6, a spring 7, an internally threaded sleeve 8, a threaded rod 9, an arc-shaped rust-removing plate 10, and toothed blocks 19. The slide groove 5 is located at the middle position of the bottom of the U-shaped mounting base 1, near the motor shaft 11. The slider 6 is slidably mounted inside the slide groove 5. A spring 7 connected to the slider 6 is located on one side inside the slide groove 5. An internally threaded sleeve 8 is mounted on the top of the slider 6. A threaded rod 9 extending to the outside of the internally threaded sleeve 8 is threaded inside the internally threaded sleeve 8. An arc-shaped rust-removing plate 10 is rotatably mounted on the top of the threaded rod 9, and the arc-shaped rust-removing plate 10 fits against the outside of the motor shaft 11. A connecting rod 4 is mounted on one end of the back of the internally threaded sleeve 8. Toothed blocks 19 are evenly arranged on one end of the front of the connecting rod 4, near the incomplete gear 2, and the toothed blocks 19 mesh with the incomplete gear 2, which facilitates the grinding function on the outside of the motor shaft 11, thereby improving the practicality and flexibility of the equipment in later use.

[0025] Both sets of arc-shaped fixing plates 15 on the same side have internal threaded holes on opposite sides, and these internal threaded holes cooperate with the bidirectional screw 14. This facilitates the threaded engagement design between the arc-shaped fixing plates 15 and the bidirectional screw 14, allowing the bidirectional screw 14 to drive the arc-shaped fixing plates 15 to move away from or towards each other when it rotates. The motor 13 has an external mounting compartment with protective cotton on the inside, facilitating the installation and protection of the motor 13. The U-shaped mounting base 1 has a rotating shaft at the top center of the side away from the motor 13, and this shaft is connected to another set of guide rails 16, facilitating the installation and rotation of the other set of guide rails 16. This also allows the motor shaft 11 to be installed and rotated later.

[0026] Working principle: When in use, the device can be moved to the designated location and the power supply can be connected. Then, the motor shaft 11 is placed inside the arc-shaped fixing plate 15. By rotating the bidirectional screw 14, the two sets of arc-shaped fixing plates 15 can be driven to move closer inside the guide rail 16, thereby completing the fixing and limiting of the motor shaft 11. This facilitates the subsequent rust removal operation of the motor shaft 11 without the need for manual holding by the operator, thus improving the stability of fixing the motor shaft 11 in the later stage.

[0027] Simultaneously, the rotation of the rotating rod 12 and above can be achieved by the drive of the motor 13. Then, the rotation of the motor shaft 11 can be achieved by the connection of the guide rail 16. Finally, the rotation of the rotating rod 3 and the incomplete gear 2 can be achieved by the meshing design of the bevel gear 18 and the bevel gear 17. The meshing design of the incomplete gear 2 and the tooth block 19 can drive the connecting rod 4 to pull the internal thread sleeve 8 and above to move, thereby realizing the movement of the arc-shaped rust removal plate 10 outside the motor shaft 11. At the same time, the internal thread sleeve 8 can also drive the slider 6 to move inside the slide groove 5 to stretch the spring 7. When the incomplete gear 2 continues to rotate and disengages from the tooth block 19, the elastic restoring force of the spring 7 can drive the arc-shaped rust removal plate 10 to return to its original state, so as to facilitate the reciprocating movement and grinding operation of the arc-shaped rust removal plate 10 in the later stage. Thus, the automatic rust removal and grinding function of the equipment can be realized, eliminating the need for operators to manually hold the rust removal and grinding machine and reducing the labor intensity of workers in the later stage.

[0028] Finally, through the structural design of the guide rail 16, the bidirectional screw 14 and the arc-shaped fixing plate 15, it is also possible to fix and clamp motor shafts 11 of different diameters. Then, with the threaded engagement design of the internal threaded sleeve 8 and the threaded rod 9, the height of the arc-shaped rust removal plate 10 can be adjusted to facilitate the rust removal operation of motor shafts 11 of different diameters in the later stage, and increase the flexibility of the equipment in the later use.

[0029] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
