Description

Technical Field

[0001] This utility model mainly relates to the field of bearing processing technology, specifically a bearing surface treatment device. Background Technology

[0002] As a key component in mechanical equipment, the surface treatment quality of bearings directly affects their performance, lifespan, and reliability. In the bearing production process, spraying is a common surface treatment method, which aims to provide a protective coating to the bearing surface and enhance its wear resistance, corrosion resistance, and other properties.

[0003] In actual use, most existing bearing surface treatment devices can only spray one surface of the bearing. If the other side of the bearing needs to be sprayed, it is necessary to manually rotate the bearing. This not only increases the labor intensity of the operators, but also easily leads to the interruption of the spraying operation, affecting production efficiency. At the same time, manual rotation makes it difficult to ensure the consistency of bearing positioning each time, thus affecting the stability of the spraying quality. Utility Model Content

[0004] The purpose of this invention is to solve the problems of existing bearing surface spraying devices being unable to automatically spray both sides of the bearing, resulting in high labor intensity, low production efficiency, and unstable spraying quality, and to propose a bearing surface treatment device.

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

[0006] A bearing surface treatment device includes a housing, a reciprocating lead screw rotatably mounted inside the housing, a movable block on the reciprocating lead screw, a spraying mechanism on the movable block, a trigger rod fixedly connected to the lower end of the movable block, a support tube fixedly mounted inside the housing, a rotating mechanism on the support tube, the rotating mechanism including a support plate rotatably mounted on the support tube, a transmission rod at the lower end of the support plate capable of adjusting the rotation of the support plate, the transmission rod being positioned directly below the trigger rod, and the transmission rod and the trigger rod having a partial overlap area on the horizontal projection plane.

[0007] As a further description of the above technical solution, the rotating mechanism also includes a rotating block rotatably installed inside the support tube. The rotating block is fixedly connected to the lower end of the support plate. A rotating groove is formed on the outer surface of the rotating block. The rotating groove is composed of two L-shaped grooves connected end to end. Each L-shaped groove is composed of an oblique groove and a vertical groove. The two L-shaped grooves are centrally symmetrically arranged along the circumference of the rotating block on the outer surface of the rotating block. Sliding holes are formed on the support tube at positions corresponding to the two vertical grooves. Sliding blocks are slidably installed in each of the two sliding holes. The ends of the two sliding blocks that are close to each other extend into the rotating groove and are slidably connected to the rotating groove. Support rods are fixedly connected to the ends of the two sliding blocks that are far apart from each other. The transmission rod is fixedly connected to the support rod. A spring is fixedly installed between the rotating block and the bottom end of the housing.

[0008] As a further description of the above technical solution, a motor is fixedly installed at the upper end of the housing, the output end of the motor passes through the housing and is fixedly connected to a reciprocating lead screw, a limit rod is fixedly installed inside the housing, and the limit rod passes through a moving block and is slidably connected to the moving block.

[0009] As a further description of the above technical solution, the spraying mechanism includes a spray gun fixedly installed on a movable block, a paint bucket fixedly installed on the outside of the housing, a filling port on the paint bucket, and a flexible conduit connecting the paint bucket and the spray gun.

[0010] As a further description of the above technical solution, the feeding port is provided with a screw cap, and the screw cap is threadedly installed on the feeding port.

[0011] As a further description of the above technical solution, the support plate is provided with a fixing mechanism, the fixing mechanism includes a fixing plate, both ends of the fixing plate are provided with threaded rods, both threaded rods pass through the fixing plate and extend into the support plate, the two threaded rods are threadedly connected to the fixing plate and the support plate respectively, and the upper ends of the two threaded rods are fixedly connected with knobs.

[0012] As a further description of the above technical solution, a door is provided on one side of the box body, and glass plates are provided on both the side of the box body adjacent to the door and on the door.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. In this utility model, due to the cooperation between the trigger rod and the transmission rod, when the spraying mechanism descends to the bottom of the bearing, the trigger rod at the lower end of the moving block will contact the transmission rod in the rotating mechanism and drive it to move down, causing the support plate in the rotating mechanism to rotate, thereby realizing the automatic rotation of the bearing. No manual operation is required, which greatly reduces labor intensity and improves production efficiency.

[0015] 2. In this utility model, since the bearing is rotated automatically through a precisely designed mechanical structure, compared with manual rotation, it can better ensure the consistency of bearing positioning each time, thereby effectively improving the stability of spraying quality and ensuring the uniformity and integrity of the bearing surface coating.

[0022] To facilitate understanding of this utility model, a more comprehensive description of the utility model will be given below with reference to the accompanying drawings, which show several embodiments of the utility model. However, the utility model can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the disclosure of the utility model more thorough and comprehensive.

[0023] Please refer to the appendix carefully. Figures 1-4As shown, this utility model provides a technical solution: a bearing surface treatment device, including a housing 10, a reciprocating screw 11 rotatably installed inside the housing 10, a moving block 14 on the reciprocating screw 11, a spraying mechanism on the moving block 14, a trigger rod 141 fixedly connected to the lower end of the moving block 14, a support tube 20 fixedly installed inside the housing 10, a rotating mechanism on the support tube 20, the rotating mechanism including a support plate 22 rotatably installed on the support tube 20, a transmission rod 24 at the lower end of the support plate 22 capable of adjusting the rotation of the support plate 22, the transmission rod 24 being located directly below the trigger rod 141, and the transmission rod 24 and the trigger rod 141 having a partial overlap area on the horizontal projection plane. When the reciprocating screw 11 rotates and drives the moving block 14 to descend, no additional manual operation is required; the trigger rod 141 descends to a specific position and interacts with the transmission rod 24. This process automatically triggers the rotation of the support plate 22, realizing the rotation of the bearing, with fully automated operation, greatly reducing manual intervention and labor intensity.

[0024] In one embodiment of this utility model, such as Figure 2 and Figure 3 As shown, the rotating mechanism also includes a rotating block 21 rotatably installed inside the support tube 20. The rotating block 21 is fixedly connected to the lower end of the support plate 22. A rotating groove 211 is formed on the outer surface of the rotating block 21. The rotating groove 211 is composed of two L-shaped grooves connected end to end. Each L-shaped groove is composed of an oblique groove and a vertical groove. The two L-shaped grooves are centrally symmetrically arranged on the outer surface of the rotating block 21 along the circumference of the rotating block 21. This unique shape design allows the linear motion of the transmission rod 24 to be accurately converted into the rotation of the support plate 22 through the cooperation of the slider 231 and the rotating groove 211. The support tube 20 has sliding holes 201 at the corresponding positions of the two vertical slots. Sliding blocks 231 are slidably installed in the two sliding holes 201. The ends of the two sliding blocks 231 that are close to each other extend into the rotating groove 211 and are slidably connected to the rotating groove 211. The ends of the two sliding blocks 231 that are far apart from each other are fixedly connected to the support rod 23. The transmission rod 24 is fixedly connected to the support rod 23. A spring 25 is fixedly installed between the rotating block 21 and the bottom end of the housing 10. When the trigger rod 141 moves upward and the transmission rod 24 no longer applies downward force, the rotating block 21 can be restored to its initial position.

[0025] Specifically, when the trigger rod 141 moves down and drives the transmission rod 24 to move vertically downward, the support rod 23 drives the two sliders 231 to slide in the rotating groove 211. First, the rotating block 21 rotates 180 degrees along the inclined groove, and then the position of the rotating block 21 is kept stable along the vertical groove. The support plate 22 on the rotating block 21 is further rotated 180 degrees, realizing the automatic flipping of the bearing. This facilitates the spraying of the other side of the bearing without manual intervention, greatly improving the continuity and efficiency of the spraying operation.

[0026] In one embodiment of this utility model, such as Figure 1 and Figure 2 As shown, a motor 13 is fixedly installed at the upper end of the housing 10. The output end of the motor 13 passes through the housing 10 and is fixedly connected to the reciprocating lead screw 11. The motor 13 can drive the reciprocating lead screw 11 to rotate. A limit rod 12 is fixedly installed inside the housing 10. The limit rod 12 passes through the moving block 14 and is slidably connected to the moving block 14. The function of the limit rod 12 is to restrict the moving block 14 to move linearly only along the direction of the limit rod 12, ensuring that the moving block 14 will not shake or deviate during the up and down movement, thus ensuring the stability and accuracy of the spraying mechanism's movement.

[0027] In one embodiment of this utility model, such as Figure 1 and Figure 2 As shown, the spraying mechanism includes a spray gun 15 fixedly mounted on a movable block 14. A paint bucket 17 is fixedly mounted on the outside of the housing 10. The paint bucket 17 is provided with a feeding port 171. The paint bucket 17 and the spray gun 15 are connected by a flexible conduit 16. The spray gun 15 is fixedly mounted on the movable block 14. The movable block 14 can move with the reciprocating screw 11, which can flexibly adjust the position of the spray gun 15 to spray different parts of the bearing. At the same time, the flexible conduit 16 connects the paint bucket 17 and the spray gun 15, which not only ensures the supply of paint, but also does not hinder the movement of the spray gun 15, allowing the spray gun 15 to move freely within a certain range to ensure uniform spraying of the bearing surface.

[0028] In one embodiment of this utility model, such as Figure 2 and Figure 4 As shown, a cap 18 is provided on the feeding port 171. The cap 18 is threaded onto the feeding port 171. By setting the cap 18, the spraying material or other substances used for bearing surface treatment inside the housing 10 can be prevented from leaking. At the same time, external dust, impurities and other contaminants can be prevented from entering the housing 10 and affecting the treatment effect.

[0029] In one embodiment of this utility model, such as Figure 2 and Figure 3 As shown, a fixing mechanism is provided on the support plate 22. The fixing mechanism includes a fixing plate 26, and threaded rods 27 are provided at both ends of the fixing plate 26. Both threaded rods 27 pass through the fixing plate 26 and extend into the support plate 22. The two threaded rods 27 are threadedly connected to the fixing plate 26 and the support plate 22, respectively. A knob 28 is fixedly connected to the upper end of each threaded rod 27. By rotating the knob 28, the threaded rods 27 are driven to rotate. Since the threaded rods 27 are threadedly connected to the fixing plate 26 and the support plate 22, the threaded rods 27 will move up and down under the action of the threads when rotating, thereby driving the fixing plate 26 to move closer to or away from the support plate 22. This can vertically clamp and fix the bearing between the fixing plate 26 and the support plate 22, ensuring that the bearing will not move or shake when the bearing is surface treated, and ensuring the consistency and stability of the treatment effect.

[0030] In one embodiment of this utility model, such as Figure 1 As shown, a door 19 is provided on one side of the box 10. A glass plate 101 is provided on the side of the box 10 adjacent to the door 19 and on the door 19. The glass plate 101 provides the operator with a window to observe the inside of the box 10.

[0031] The present invention has been described above by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvement made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, shall be within the protection scope of the present invention.
