Description

Technical Field

[0001] This utility model relates to the field of bearing processing equipment technology, and in particular to an insulating bearing spraying fixture. Background Technology

[0002] In motors or high-voltage equipment, uneven voltage can generate current across the bearing. This current can create a short circuit through the bearing's outer diameter, causing the bearing to overheat, deteriorate the lubricating grease, and accelerate bearing aging. To address this, a high-quality coating needs to be sprayed onto the outer surface of the bearing. This coating has strong adhesion to the substrate and good insulation properties, which can prevent the induced current from causing electro-erosion on the bearing, prevent damage to the lubricating grease, rolling elements, and raceways, and improve the bearing's service life.

[0003] To ensure coating quality, existing bearings need to be fixed in place using a fixture to prevent them from shaking or shifting during the coating process. However, in actual use, the clamping blocks of traditional fixtures can obstruct the bearing surface after clamping, requiring repositioning after coating. This makes it impossible to complete the coating evenly and effectively. Therefore, an insulated bearing coating fixture is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an insulating bearing spraying fixture, which aims to improve the problem that the clamping blocks in the prior art can obstruct the bearing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An insulating bearing spraying fixture includes a base, a drive assembly installed inside the base, a round rod installed on the top of the drive assembly, a support plate fixedly connected to the top of the round rod, a slide rod fixedly connected to the outside of the support plate, a connecting plate slidably connected to the outer periphery of the slide rod, a bearing body slidably connected to the outside of the connecting plate, a locking block fixedly connected to the outside of the connecting plate, and an elastic component installed between the support plate and the connecting plate.

[0007] The elastic component includes a stop block, which is fixedly connected to the end of the slide rod away from the support plate, and a compression spring is sleeved on the outer periphery of the slide rod;

[0008] As a further description of the above technical solution:

[0009] The base has a groove in the middle, a toothed ring is fixedly connected to the middle of the groove, and a gear is fixedly connected to the outer periphery of the round rod, the gear meshing with the toothed ring;

[0010] As a further description of the above technical solution:

[0011] The drive assembly includes a rotary motor, which is fixedly connected inside the base. A rotating plate is rotatably connected to the center of the groove. The rotating plate is fixedly connected to the output end of the rotary motor. The round rod is rotatably connected to the top of the rotating plate.

[0012] As a further description of the above technical solution:

[0013] Both the connecting plate and the card block have through holes in their middle parts, and the blocking block is slidably connected to the middle part of the through holes;

[0014] As a further description of the above technical solution:

[0015] The card block is triangular in shape;

[0016] As a further description of the above technical solution:

[0018] As a further description of the above technical solution:

[0019] The round rod is rotatably connected to the off-center position of the rotating plate;

[0020] As a further description of the above technical solution:

[0021] The toothed ring is located above the rotating plate.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the bearing body is first pressed down from above the connecting plate. Under the action of the inclined surface of the locking block, the bearing body will push the locking block, thereby causing the connecting plate to slide around the slide rod and squeeze the compression spring. When the bearing body slides between the two locking blocks, the compression spring will push the connecting plate to fix the bearing body on the outer periphery of the connecting plate, so as to prevent the fixture from obstructing the surface of the bearing body and ensure the spraying effect.

[0024] 2. In this utility model, when the drive motor rotates the rotating plate, the rotating plate rotates the round rod together, so that the multiple bearing bodies fixed on the top of the rotating plate can rotate around the rotating motor. At the same time, under the action of the gear ring, the gear can be driven to rotate. The gear drives the bearing body to rotate through the round rod, so that the bearing body can rotate on its own axis while revolving around the central axis, thereby further improving the uniformity of the spraying.

[0031] 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.

[0032] Reference Figures 1-3An embodiment of this utility model provides an insulating bearing spraying fixture, comprising a base 1, a drive assembly installed inside the base 1, a round rod 8 installed on the top of the drive assembly, a support plate 4 fixedly connected to the top of the round rod 8, a slide rod 13 fixedly connected to the outside of the support plate 4, a connecting plate 10 slidably connected to the outer periphery of the slide rod 13, a bearing body 3 slidably connected to the outer periphery of the connecting plate 10, a locking block 7 fixedly connected to the outer periphery of the connecting plate 10, an elastic component installed between the support plate 4 and the connecting plate 10, the elastic component including a blocking block 15, the blocking block 15 fixedly connected to the end of the slide rod 13 away from the support plate 4, a compression spring 14 sleeved on the outer periphery of the slide rod 13, through holes 9 opened in the middle of both the connecting plate 10 and the locking block 7, the blocking block 15 slidably connected in the middle of the through holes 9, the locking block 7 being triangular in shape, and a locking groove provided between the locking block 7 and the connecting plate 10. First, the bearing body 3 is pressed downwards from above the connecting plate 10. Supported by the support plate 4, the bearing body 3 will press against the inclined surface of the locking block 7, thereby causing the connecting plate 10 to slide around the outer periphery of the slide rod 13 and press against the compression spring 14. When the bearing body 3 slides between the two locking blocks 7, the compression spring 14 is no longer compressed and pushes the connecting plate 10 to reset, thereby fixing the bearing body 3 in the slot between the connecting plate 10 and the two locking blocks 7, and locking the bearing body 3 between the two locking blocks 7. When the connecting plate 10 and the locking blocks 7 slide, the slide rod 13 will drive the blocking block 15 to slide in the middle of the through hole 9. When the compression spring 14 drives the connecting plate 10 to reset, the blocking block 15 and the through hole 9 can prevent the connecting plate 10 from falling off the slide rod 13, so as to prevent the fixture from obstructing the surface of the bearing body 3 and ensuring the spraying effect.

[0033] Reference Figure 1 and Figure 4 The drive assembly includes a rotary motor 12, which is fixedly connected inside the base 1. A rotating plate 2 is rotatably connected to the center of a groove 11, and the rotating plate 2 is fixedly connected to the output end of the rotary motor 12. A round rod 8 is rotatably connected to the top of the rotating plate 2. A groove 11 is provided in the center of the base 1, and a gear ring 6 is fixedly connected to the center of the groove 11. A gear 5 is fixedly connected to the outer periphery of the round rod 8, and the gear 5 meshes with the gear ring 6. The round rod 8 is rotatably connected at an off-center position of the rotating plate 2, and the gear ring 6 is located above the rotating plate 2. When the rotary motor 12 drives the rotating plate 2 to rotate, the rotating plate 2 will drive the round rod 8 to rotate together, so that the multiple bearing bodies 3 fixed on the top of the rotating plate 2 can rotate around the rotary motor 12. Since the gear 5 and the gear ring 6 are in a meshing state, the round rod 8 rotates while the gear ring 6 pushes the gear 5, so that the gear 5 drives the round rod 8 to rotate. The bearing bodies 3 installed on the top of the round rod 8 will rotate together, so that the bearing bodies 3 can rotate on their own axis while revolving around the central axis, thereby further improving the uniformity of the spraying.

[0034] Working principle: First, the bearing body 3 is pressed downward from above the connecting plate 10. Under the action of the inclined surface of the locking block 7, the bearing body 3 will push the locking block 7, thereby causing the connecting plate 10 to slide around the slide rod 13 and squeeze the compression spring 14. When the bearing body 3 slides between the two locking blocks 7, the compression spring 14 is no longer squeezed, and at the same time, it pushes the connecting plate 10 to reset, thereby fixing the bearing body 3 on the outer periphery of the connecting plate 10 and locking the bearing body 3 between the two locking blocks 7, so as to prevent the fixture from obstructing the surface of the bearing body 3 and ensuring the spraying effect.

[0035] When the drive motor 12 drives the rotating plate 2 to rotate, the rotating plate 2 drives the round rod 8 to rotate together, so that the multiple bearing bodies 3 fixed on the top of the rotating plate 2 can rotate around the rotating motor 12. While rotating, the round rod 8 can move the gear 5 under the action of the gear ring 6, so that the gear 5 drives the round rod 8 to rotate. The bearing bodies 3 installed on the top of the round rod 8 will rotate together, so that the bearing bodies 3 can rotate on their own axis while revolving around the center, thereby further improving the uniformity of the spraying.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
