Description

Technical Field

[0001] This utility model relates to the field of motor manufacturing equipment technology, specifically to an insulating paint spraying device for a cast aluminum rotor production line. Background Technology

[0002] In the motor manufacturing process, the spraying of insulating varnish on cast aluminum rotors is one of the key steps. Traditional manual painting methods are inefficient, struggle to guarantee uniform varnish thickness and quality stability, and are labor-intensive. Existing automated spraying equipment suffers from problems such as insufficient targeting of cast aluminum rotors, significant varnish waste and environmental pollution, and high maintenance costs. With the rapid development of the motor industry, there is an urgent need for a high-efficiency, high-quality, environmentally friendly, and low-cost insulating varnish spraying device for cast aluminum rotors.

[0003] Existing spraying equipment uses a fixed-point spraying method, which limits the overall spraying angle and makes it difficult to evenly coat the surface of the cylindrical rotor. In addition, existing spraying equipment requires clamping equipment to clamp and limit the rotor. When dealing with rotor structures with special shapes, the clamping part is prone to covering the area to be sprayed with insulating varnish, resulting in uneven varnish layer and affecting the insulation performance and overall quality of the rotor. Utility Model Content

[0004] The purpose of this utility model is to provide an insulating varnish spraying device for a cast aluminum rotor production line, so as to solve the problems mentioned in the background art, which are that the fixed-point spraying method is used for operation, which limits the overall spraying angle and makes it difficult to uniformly coat the surface of the cylindrical rotor. In addition, when the traditional clamping structure is used for rotor structure with special shape, the clamping part is easy to cover the insulating varnish spraying position, resulting in uneven varnish layer.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an insulating paint spraying device for a cast aluminum rotor production line, including a base, which is configured as a rectangular platform structure. A displacement frame is slidably connected to the upper end of the base, and two electrically driven turntables are symmetrically arranged on the upper end of the displacement frame. A positioning column is provided on the upper end of the electrically driven turntable, and the positioning column provides a limit for the spraying operation of the cast aluminum rotor.

[0006] The upper end of the base is provided with a strip-shaped opening, and an electric gear rod is horizontally arranged in the strip-shaped opening of the base. The electric gear rod is meshed with the tooth block at the bottom of the displacement frame. The two sides of the displacement frame are provided with protruding structures that are slidably connected to the strip-shaped opening of the base. The positioning column is installed with the limiting component to provide vertical limiting for the spraying operation of the cast aluminum rotor.

[0007] The base is equipped with a protective plate, which is an arc-shaped plate structure and is symmetrically arranged on both sides of the displacement frame. The inner wall of the protective plate is slidably connected to the annular slide rail frame, and a lifting column is installed at the upper end of the annular slide rail frame. An annular guide rail slide is provided in the slide rail of the annular slide rail frame, and a high-pressure airless nozzle assembly is provided on one side of the annular guide rail slide, and the high-pressure airless nozzle assembly is connected to the paint high-pressure pump.

[0008] By adopting the above technical solution and optimizing the spraying path, it is ensured that the insulating varnish forms a uniform coating on the surface of the cast aluminum rotor.

[0009] Preferably, the limiting component includes:

[0010] A lifting rod sleeve is installed on the upper end of the positioning column, and the lifting rod sleeve is aligned with the axis of the positioning column;

[0011] A flexible rubber tube, with its two ends respectively penetrated by the positioning post and the lifting rod sleeve, and the flexible rubber tube is set in a cylindrical shape;

[0012] Rubber sheets are installed on the outer wall of the flexible rubber tube, and the rubber sheets are equidistantly arranged on the outer wall of the flexible rubber tube.

[0013] The pressing frame is engaged with the top end of the lifting rod sleeve, and the pressing frame is configured as a T-shaped structure.

[0014] Using the above technical solution, the limiting component adopts a structure that contacts the inner hole of the cast aluminum rotor to limit the cast aluminum rotor and avoids intercepting the position of the insulating varnish spraying on the cast aluminum rotor.

[0015] Preferably, a spring structure is provided between the lifting rod sleeve and the positioning column, and the lifting rod sleeve and the flexible rubber tube are connected in a concentric circle.

[0016] The above technical solution enables the lifting rod sleeve and the positioning column to guide each other during use.

[0017] Preferably, a positioning plate is installed at the upper end of the protective plate, and a high-pressure paint pump is installed inside the positioning plate, wherein there are four high-pressure paint pumps.

[0018] Using the above technical solution, a structure is constructed by assembling protective plates and positioning plates to intercept splashed paint.

[0019] Preferably, the bottom end of the positioning plate is installed with the lifting column, and the lifting column is a three-section sliding connection sleeve rod.

[0020] By adopting the above technical solution, the positioning plate is installed with the lifting column to limit the position of the lifting column.

[0021] Preferably, the upper end of the high-pressure paint pump is connected to the paint tank, and the high-pressure paint pump is connected to the high-pressure airless nozzle assembly through a pipeline.

[0023] Preferably, the high-pressure airless nozzle group consists of identical nozzles stacked vertically, and the spraying direction of the high-pressure airless nozzle group is towards the positioning column.

[0024] Using the above technical solution, the number of high-pressure airless nozzle groups can be further expanded according to the installation environment required by the cast aluminum rotor.

[0025] Compared with the prior art, the beneficial effects of this utility model are: the insulating paint spraying device used in this aluminum casting rotor production line:

[0026] 1. The device uses positioning posts and limiting posts to construct a limiting structure that penetrates the middle hole of the cast aluminum rotor. Through the structure of the rubber sheet abutting against the hole of the cast aluminum rotor, the rubber sheet adjusts the shape of the gas inside the flexible rubber tube according to the change of the inner diameter of the cast aluminum rotor, making the flexible rubber tube narrower and longer. This causes the lifting rod sleeve to rise and maintain the limiting clamping between it and the cast aluminum rotor, reducing excessive contact with the outer layer of insulating paint spraying position of the cast aluminum rotor. When used with cast aluminum rotors with larger inner holes, the pressing frame squeezes the flexible rubber tube connected to the top of the lifting rod sleeve, causing the positioning post and the lifting rod sleeve to move closer to each other and compress the height of the flexible rubber tube, increasing the diameter of the flexible rubber tube and allowing the rubber sheet to contact the inner hole of the cast aluminum rotor to achieve limiting clamping.

[0027] 2. A circular slide rail frame and a circular guide rail slide table are used to form a spraying path around the outer layer of the cast aluminum rotor. The height of the circular slide rail frame can be adjusted to create an environment for vertical and circular spraying. This makes the spraying operation of the high-pressure airless nozzle group more precise, reduces paint splashing and waste, and further optimizes the spraying effect. It can ensure that the insulating varnish forms a uniform coating on the surface of the cast aluminum rotor, avoiding the problem of inconsistent paint layer thickness that may be caused by manual painting. This improves the insulation performance of the rotor and ensures the stable operation of the motor. Attached Figure Description

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] Please see Figure 1-6 This utility model provides a technical solution: an insulating paint spraying device for a cast aluminum rotor production line, comprising a base 1, a displacement frame 2, an electric gear rod 3, an electric drive turntable 4, a positioning column 5, a lifting rod sleeve 6, a flexible rubber tube 7, a rubber sheet 8, a pressing frame 9, a protective plate 10, an annular slide rail frame 11, a lifting column 12, a positioning plate 13, a paint high-pressure pump 14, a high-pressure airless nozzle assembly 15, and an annular guide rail slide table 16;

[0037] Among them, the base 1 is set as a rectangular platform structure. The upper end of the base 1 is slidably connected to the displacement frame 2, and two electric drive turntables 4 are symmetrically arranged on the upper end of the displacement frame 2. The upper end of the electric drive turntable 4 is provided with positioning columns 5, which provide a limit for the aluminum rotor spraying operation.

[0038] The upper end of the base 1 is provided with a strip-shaped opening, and an electric gear rod 3 is horizontally arranged in the strip-shaped opening of the base 1. The electric gear rod 3 is meshed with the tooth block at the bottom of the displacement frame 2. The two sides of the displacement frame 2 are provided with protruding structures that are slidably connected to the strip-shaped opening of the base 1. The positioning column 5 is installed with the limiting component to provide vertical limiting for the spraying operation of the cast aluminum rotor.

[0039] The base 1 is equipped with a protective plate 10, which is an arc-shaped plate structure. The protective plates 10 are symmetrically arranged on both sides of the displacement frame 2. The inner wall of the protective plate 10 is slidably connected to the annular slide rail frame 11. A lifting column 12 is installed on the upper end of the annular slide rail frame 11. A positioning plate 13 is installed on the upper end of the protective plate 10. A high-pressure paint pump 14 is installed inside the positioning plate 13. The high-pressure paint pump 14 has four positioning plates 13. The bottom end of the positioning plate 13 is installed with the lifting column 12. The lifting column 12 is a three-section sliding plate. The sleeve rod of the movable connection, the slide rail frame 11 is provided with an annular guide rail slide table 16 in the slide rail, and a high pressure airless nozzle group 15 is provided on one side of the annular guide rail slide table 16. The high pressure airless nozzle group 15 is connected to the paint high pressure pump 14. The upper end of the paint high pressure pump 14 is connected to the paint tank, and the paint high pressure pump 14 is connected to the high pressure airless nozzle group 15 through the pipeline. The high pressure airless nozzle group 15 is installed by stacking the same nozzles in a vertical direction, and the spraying direction of the high pressure airless nozzle group 15 is towards the positioning column 5.

[0040] Referring to the attached diagrams in the instruction manual Figure 1-6 As shown, the base 1 limits the movement of the displacement frame 2 through a strip-shaped opening. An electric gear rod 3, connected to the bottom of the displacement frame 2 and powered by the production workshop's electrical system, pushes the displacement frame 2 left and right, enabling uninterrupted spraying operations. The cast aluminum rotor at the top of the moved displacement frame 2 is rotated by an electrically driven turntable 4 to adjust the material-picking angle, facilitating the removal of the cast aluminum rotor from the top of the positioning post 5. The protective plate 10 located at the top of the base 1... Figure 1-2 As shown, during spraying, insulating varnish is added to the paint tank connected to the high-pressure paint pump 14. The high-pressure paint pump 14 then delivers the insulating varnish to the connected high-pressure airless nozzle assembly 15. The high-pressure airless nozzle assembly 15 moves along the same trajectory as the annular guide rail slide 16. The annular guide rail slide 16 moves along the annular track of the annular slide rail frame 11. After each rotation, it moves in the opposite direction. The height of the annular slide rail frame 11 is adjusted by the lifting column 12 to facilitate uniform spraying on the surface of the cast aluminum rotor. The number of high-pressure airless nozzle assemblies 15 can be adjusted and disassembled as needed to adapt the high-pressure airless nozzle assemblies 15 to work with cast aluminum rotors of different lengths and models. The positioning plate 13 restricts the installation position of the lifting column 12. At the same time, the positioning plate 13 is installed with the protective plate 10 to intercept the paint splashed outward during spraying.

[0041] The limit components include:

[0042] The lifting rod sleeve 6 is installed on the upper end of the positioning column 5, and the lifting rod sleeve 6 is aligned with the axis of the positioning column 5. A spring structure is provided between the lifting rod sleeve 6 and the positioning column 5, and the lifting rod sleeve 6 and the flexible rubber tube 7 are connected in a concentric circle.

[0043] The flexible rubber tube 7 is penetrated at both ends by the positioning post 5 and the lifting rod sleeve 6, and the flexible rubber tube 7 is cylindrical.

[0044] Rubber sheet 8 is installed on the outer wall of flexible rubber tube 7, and the rubber sheet 8 is equidistantly arranged on the outer wall of flexible rubber tube 7.

[0045] The pressing frame 9 is engaged with the top end of the lifting rod sleeve 6, and the pressing frame 9 is configured as a T-shaped structure;

[0046] Referring to the attached diagrams in the instruction manual Figure 1-6 As shown, the lifting rod sleeve 6 and the positioning column 5 form a column structure perpendicular to the upper end of the electric drive turntable 4. When used with a cast aluminum rotor, the inclined structure at the top of the rubber sheet 8 allows for... Figure 2-5 As shown, the cast aluminum rotor is guided to slide down through the middle hole, and the distance between the rubber sheets 8 decreases. After being squeezed, the flexible rubber tube 7 becomes narrow and long, which increases the distance between the lifting rod sleeve 6 inside the flexible rubber tube 7 and the positioning post 5. When the diameter of the middle hole of the cast aluminum rotor is larger than the diameter of the flexible rubber tube 7, a pressing frame 9 of appropriate length is selected and inserted from the upper end of the hole of the cast aluminum rotor. The pressing frame 9 squeezes the lifting rod sleeve 6 down to be close to the positioning post 5. At this time, the flexible rubber tube 7 expands outward and increases its diameter due to the change in the height distance between the positioning post 5 and the lifting rod sleeve 6. This makes the rubber sheet 8 stick tightly to the inner wall of the rotor during the insertion of the cast aluminum rotor, thereby achieving the limitation of the stator.

[0047] Working principle: When using the insulating paint spraying device for the cast aluminum rotor production line, the electric gear rod 3 pushes out one end of the displacement frame 2, and the middle hole of the cast aluminum rotor is inserted from the upper end of the lifting rod sleeve 6. The cast aluminum rotor is guided to descend by the conical setting at the upper end of the rubber sheet 8. As the diameter of the inner hole of the cast aluminum rotor affects the spacing between the constricting rubber sheets 8, the flexible rubber tube 7 inside the rubber sheet 8 becomes narrow and elongated, pushing up the lifting rod sleeve 6 and passing through the top of the cast aluminum rotor. After the appropriate diameter pressing frame 9 is inserted, the position of the cast aluminum rotor is restricted. As the displacement frame 2 enters the center of the base 1, the lifting column 1... 2. The annular slide rail frame 11 is pushed down, so that the height of the lowest nozzle of the high-pressure airless nozzle group 15 is aligned with the lowest spraying position of the insulating varnish on the cast aluminum rotor. The high-pressure pump 14 and the high-pressure airless nozzle group 15 start spraying. During spraying, four annular guide rail slides 16 rotate along the track of the annular slide rail frame 11, surrounding the cast aluminum rotor. As the annular slide rail frame 11 slowly rises, the four annular guide rail slides 16 rotate one revolution and then rotate in the opposite direction to perform reciprocating rotation, thereby realizing the spraying operation of insulating varnish on the surface of the cast aluminum rotor and increasing the overall practicality.

[0048] 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.
