Description

Technical Field

[0001] The invention relates to the field of painting, and in particular to a rotor core outer surface protection treatment device. Background Art

[0002] The rotor core is a rotating component inside the brake motor. The rotor core and the stator together constitute an important part of the brake motor. In order to prevent moisture and corrosion, and to strengthen the insulation performance between the windings, it is generally necessary to paint the surface of the rotor core. The existing painting method generally uses a coating roller to fit the rotor core curved surface to the coating roller, and then the rotor core rotates. The rotation of the rotor core causes the entire curved surface to rotate one circle, so that the coating roller can completely paint the curved surface of the rotor core. However, since the rotor core is not all regular cylinders, some of the rotor cores are cylinders with cross-sections on the curved surface. When painting this rotor core, since the distance between the rotor core and the coating roller is fixed, the extrusion force of the coating roller when in contact with the rotor core curved surface is fixed, but the coating When the roller contacts the cross-section of the rotor core curved surface, since the cross-section is formed by cutting out part of the volume of the rotor core curved surface, the distance between the cross-section and the coating roller becomes larger, and the extrusion pressure of the coating roller decreases when it contacts the cross-section of the rotor core curved surface. When the coating roller outputs the same amount of paint, a large extrusion pressure means that the paint surface is subjected to extrusion pressure, which will make the paint surface thinner and more uniform, while a reduced extrusion pressure means that the paint surface is relatively thick. As a result, when the coating roller paints the rotor core with a cross-section on the curved surface, the paint surface will be uneven.

[0003] In view of the above problems existing in the prior art, we have designed a rotor core outer surface protection treatment device with uniform paint coating. Summary of the invention

[0004] In order to overcome the shortcomings of the prior art, the present invention provides a rotor core outer surface protection treatment device with uniform paint coating.

[0014] Furthermore, the pulling frame is sleeved on the rotating assembly, and the pulling frame is used to drive the rotating assembly to move.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: the present invention is provided with a distance sensor. When the distance sensor detects that the distance between the distance sensor and the rotor core is consistent at multiple points, it indicates that the cross-section of the rotor core has rotated to be parallel to the distance sensor. At this time, the distance sensor sends a signal, so that the control module controls the brake motor to stop rotating, and at the same time controls the electric slide rail to start, so that the electric slide rail drives the movable frame to move to the left, thereby driving the scraper to move to the left, and scraping off the excessively thick paint on the cross-section of the rotor core, thereby ensuring the uniformity of the paint surface of the entire rotor core; the friction frame first contacts the painted cross-section of the rotor core, and since the outer edge of the friction frame is a slope, it can accommodate part of the paint. During the movement of the friction frame, the paint accommodated in the slope part will be squeezed, so that the paint on the cross-section after the friction frame moves is tighter, and then the excess paint is scraped off by the scraper, so that the overall paint surface of the rotor core remains uniform.

Any numerical designations such as first or second are merely exemplary and are not intended to limit the scope of the present invention in any way.

[0033] Embodiment 1: A rotor core outer surface protection treatment device, see Figure 1-Figure 12As shown, it includes a frame 1, on which a rotating component 11 is slidably arranged, the rotating component 11 includes a transmission motor, a transmission belt and a transmission wheel, the transmission wheel is connected through a transmission belt transmission, and the transmission motor controls the rotation of the transmission wheel. A coating rack 12 for painting the rotor core 13 is installed on the frame 1, and the coating rack 12 can discharge paint at a uniform speed. The frame 1 is provided with a clamping component for clamping and fixing the rotor core 13, and the clamping component is provided with symmetrically distributed support frames 14, and the support frame 14 is used to fix the rotor core 13. An electric slide rail 15 is installed on the side of the frame 1 away from the coating rack 12, and a moving frame 16 is slidably connected to the electric slide rail 15. A scraper 18 is fixedly connected to the side of the moving frame 16 close to the rotor core 13, and the scraper 18 is used to scrape off excess paint on the cross section of the rotor core 13. A scraping component for scraping off and compacting the paint is provided on the frame 1.

[0034] The scraping assembly includes a convex plate frame 2, which is fixed to the frame 1. The top of the convex plate frame 2 is provided with evenly distributed tooth-shaped protrusions. A symmetrically distributed connecting frame 21 is slidably connected to the movable frame 16. A friction frame 22 is fixedly connected to the side of the connecting frame 21 close to the rotor core 13. The side of the friction frame 22 away from the scraper 18 is an inclined surface. A spring 23 is connected between the connecting frame 21 and the movable frame 16. Staggered inclined blocks 24 are provided on the convex plate frame 2. A limiting top block 25 is slidably connected to the side of the connecting frame 21 close to the inclined block 24. The limiting top block 25 is extruded and matched with the adjacent inclined block 24, and the limiting top block 25 is extruded and matched with the tooth-shaped protrusion of the convex plate frame 2.

[0035] The clamping assembly includes a symmetrically distributed pulling frame 31, which is slidably connected to the frame 1. The pulling frame 31 is retractable, and a scale is set on the pulling frame 31. The telescopic end of the pulling frame 31 has a hole, and the telescopic end and the fixed end of the pulling frame 31 are fixed by a clamping rod. The support frame 14 is fixedly connected to the adjacent pulling frame 31, and the frame 1 is fixedly connected with symmetrically distributed springs 32. A brake motor 33 is installed on the frame 1, and the output shaft of the brake motor 33 is connected with A rope winding drum 34 is provided with symmetrically distributed pull ropes 35, and the pull ropes 35 are connected to the adjacent pulling frame 31. A distance sensor 17 is installed on the moving frame 16, and the distance sensor 17 is a multi-point sensing. The brake motor 33 and the electric slide rail 15 are electrically connected to the distance sensor 17. When the distance sensor 17 senses that the distance between the rotor core 13 and multiple points is consistent, the brake motor 33 will be controlled to stop moving, and the electric slide rail 15 will be controlled to start.

[0036] It also includes a lifting assembly for supporting the rotor core 13, the lifting assembly includes a symmetrically distributed first air cylinder 41, the first air cylinder 41 is slidably connected to the adjacent pulling frame 31, the first air cylinder 41 is connected to an air guide pipe 42, the frame 1 is connected to a symmetrically distributed second air cylinder 43, the second air cylinder 43 is connected to the adjacent air guide pipe 42, the air guide pipe 42 is provided with an expansion air block 44, the expansion air block 44 is used for emergency buffering, and the symmetrically distributed second air cylinders 43 are slidably connected to a placement frame 4 for supporting the rotor core 13.

[0037] When the rotor core 13 needs to be painted for protection, the rotor core 13 is placed between the support frames 14 on both sides, and then the brake motor 33 is started, so that the brake motor 33 drives the rope drum 34 to rotate, and the rope drum 34 pulls the pull rope 35, so that the pulling frame 31 moves toward each other, and the spring piece 32 is deformed, thereby driving the support frame 14 to move toward each other and clamp the rotor core 13, and the pulling frame 31 moves toward each other to squeeze the first air cylinder 41, so that the gas in the first air cylinder 41 enters the second air cylinder 43 along the air guide pipe 42, thereby pushing the placement frame 4 to move downward, and then the operator starts the rotating component 11, and the rotation of the rotating component 11 drives the support frame 14 to rotate, thereby driving the rotor core 13 to rotate continuously, and the coating frame 12 will be close to the surface of the rotor core 13 to paint the rotor core 13.

[0038] After the painting is completed, the operator controls the brake motor 33 to reverse, so that the brake motor 33 drives the rope drum 34 to reverse, the rope drum 34 releases the pull rope 35, the spring piece 32 is reset, and the pulling frame 31 is driven to move backward and reset, so that the support frame 14 moves backward to release the rotor core 13, and because the pulling frame 31 moves backward to pull the first air cylinder 41, the gas in the second air cylinder 43 enters the first air cylinder 41 along the air guide pipe 42, thereby driving the placement frame 4 to move upward to receive the painted rotor core 13. The operator can pre-place the unpainted rotor core 13 on the top and start the brake motor 33. Because the brake motor 33 can stop quickly and accurately position, after starting the brake motor 33, the brake motor 33 can immediately make the pulling frame 31 drive the support frame 14 to move inward. At this time, the placement frame 4 will move downward at the same time to send the painted rotor core 13 downward, so that the entire process of painting the rotor core 13 is smooth and unstuck, which can improve the overall work efficiency.

[0039] Since some rotor cores 13 are not smooth cylinders but cylinders with side cut surfaces, and the coating rack 12 cannot be adjusted according to the cut surface when painting, the coating rack 12 keeps the same distance from the curved surface of the rotor core 13 during painting, and the painting is relatively uniform, while the distance from the cut surface of the rotor core 13 is relatively long, and the thickness of the paint is thicker than the curved surface, resulting in an irregular overall paint surface of the rotor core 13. Therefore, when the distance sensor 17 detects that the distance between the coating rack 12 and the entire cut surface of the rotor core 13 to be painted is consistent, it indicates that the cut surface of the rotor core 13 rotates to be parallel to the distance sensor 17. At this time, the distance sensor 17 sends a signal, so that The control module controls the brake motor 33 to stop rotating. The brake motor 33 can immediately stop the section of the rotor core 13 that needs to be painted without generating inertial offset, so that the section of the rotor core 13 remains parallel to the scraper 18. At the same time, the electric slide rail 15 is controlled to start, so that the electric slide rail 15 drives the movable frame 16 to move to the left, thereby driving the scraper 18 to move to the left, and scraping off the excessively thick paint on the section of the rotor core 13, thereby ensuring the uniformity of the paint surface of the entire rotor core 13. When the scraper 18 moves to the far left and separates from the rotor core 13, the distance sensor 17 controls the brake motor 33 to start again through the control module, and controls the electric slide rail 15 to stop moving.

[0040] Since the distance between the coating rack 12 and the curved surface of the rotor core 13 is shorter than the distance between the cut surfaces, the coating rack 12 exerts a stronger squeezing force on the curved surface of the rotor core 13 during painting, and the paint surface of the curved surface of the rotor core 13 is more compact. Therefore, in order to further maintain the uniformity of the overall paint surface of the rotor core 13, when the movable rack 16 moves to the left and drives the scraper 18 to move to the left, the connecting rack 21 will also move to the left, so that the friction racks 22 on both sides move to the left, so that the friction rack 22 on the left side first contacts the painted cut surface of the rotor core 13. Since the outer edge of the friction rack 22 is a slope, it can accommodate part of the paint. During the process of moving to the left, the friction rack 22 will squeeze the paint accommodated in the slope part, so that the paint on the cut surface after the friction rack 22 moves is more compact, and then the excess paint is scraped off by the scraper 18, so that the overall paint surface of the rotor core 13 remains uniform, and when the connecting rack 21 moves to the left The limit top block 25 on the right side moves to the left and contacts the convex plate frame 2, and continuously moves up and down under the action of the spring 23, so that the right movable frame 16 and the friction frame 22 move up and down, and the paint surface scraped by the scraper 18 is rubbed smooth; when the scraper 18 moves to the leftmost side and disengages from the rotor core 13, the connecting frame 21 is driven to move to the left until the limit top block 25 is squeezed by the inclined block 24 on the left side, so that the two limit top blocks 25 are squeezed and move forward, so that the limit top block 25 on the left side and the adjacent inclined block 24 are located in the same straight line, and the limit top block 25 on the right side is located in front of the adjacent inclined block 24. When the scraper 18 on the next side moves to the right to scrape off excess paint, the cut surface paint is squeezed by the inclined surface of the right friction frame 22, and the left friction frame 22 continuously moves up and down through the left limit top block 25 and the convex plate frame 2 to achieve the smooth polishing of the paint surface.

[0041] Embodiment 2: Based on embodiment 1, see Figure 13-Figure 15 As shown, a heating component for accelerating the solidification of the paint is also included. The heating component includes a controller 5. The controller 5 is arranged on the support frame 14. A heating tube 51 is connected to the side of the support frame 14 close to the rotor core 13. The controller 5 is used to control the heating tube 51.

[0042] In order to accelerate the drying speed of the paint surface, the controller 5 drives the heating tube 51 to start and heat the paint surface of the rotor core 13.

[0043] It also includes symmetrically distributed connecting frames 61, which are slidably connected to adjacent pulling frames 31 respectively. A pulling frame 6 is fixedly connected to one side of the connecting frame 61 close to the rotor core 13. The pulling frame 6 is sleeved on the rotating assembly 11 and is used to drive the rotating assembly 11 to move.

[0044] When the rotor core 13 is released by the support frame 14, in order to prevent the rotor core 13 from hitting the rotating assembly 11, the support frame 14 moves away from each other, which will drive the pulling frame 6 and the connecting frame 61 to move away from each other, thereby driving the rotating assembly 11 to move away from each other, so that the rotating assembly 11 is away from the rotor core 13, and the rotor core 13 falls on the placement frame 4.

[0045] The above embodiments are provided for persons familiar with the art to implement or use the present invention. Personnel familiar with the art can make various modifications or changes to the above embodiments without departing from the inventive concept of the present invention.
