Abstract
Description
Technical Field
[0001] This utility model relates to the field of spraying equipment, specifically a spraying equipment for an impact-resistant bearing buffer layer. Background Technology
[0002] Impact-resistant bearings, as key components in mechanical equipment, are widely used in high-load, high-impact applications such as heavy machinery, rail transportation, wind power equipment, and industrial robots. To improve the service life and operational stability of bearings, a special buffer coating is often applied to the outer ring surface to enhance impact resistance, corrosion resistance, and wear resistance. The quality of the coating process directly affects the uniformity, adhesion, and final performance of the coating, thus placing high demands on the precision and reliability of the coating equipment.
[0003] However, most common bearing spraying devices use fixed clamping, which makes it difficult to quickly adjust to accommodate bearing outer rings of different diameters, and lacks an effective clamping force control mechanism, which can easily lead to workpiece surface damage or unstable clamping, affecting the spraying quality. Therefore, a spraying device for impact-resistant bearing buffer layer is proposed to address the above problems. Utility Model Content
[0004] To address the shortcomings of existing technologies, such as difficulty in quickly adjusting to accommodate bearing outer rings of different diameters and the lack of an effective clamping force control mechanism, which can easily lead to workpiece surface damage or unstable clamping and affect coating quality, this utility model proposes a spraying device for an impact-resistant bearing buffer layer.
[0005] The technical solution adopted by this utility model to solve its technical problem is: a spraying device for an impact-resistant bearing buffer layer, including a spraying box and a clamping mechanism. A drive source is provided on the rear side of the inside of the spraying box, and a bearing support is provided at the bottom of the inside of the spraying box. The output end of the drive source is set on the bearing support. The clamping mechanism includes a mounting cylinder. One end of the mounting cylinder is provided with a rotating rod, which is connected to the output end of the drive source. The upper and lower parts of the mounting cylinder are respectively provided with sliding holes. Rectangular bars are respectively fitted inside the two sliding holes. One end of the two rectangular bars is respectively provided with a clamping plate. The other end of the mounting cylinder is provided with a sealing plate. A nut is provided on the sealing plate. A threaded rod is fitted inside the nut. One end of the threaded rod is provided with a conical block. The conical surface of the conical block contacts the other end of the rectangular bar.
[0006] Preferably, a knob is provided at the other end of the threaded rod.
[0007] Preferably, the sliding hole has a limiting slider on each side, and the rectangular strip has a limiting groove on each side, with the limiting slider fitting in the limiting groove.
[0008] Preferably, a baffle is provided on one side of each of the two clamps.
[0009] Preferably, the outer clamps of the two clamps hold the outer ring of the bearing.
[0010] Preferably, a storage tank is provided on one side of the spray box, a water pump is provided on the top of the storage tank, a delivery pipe is provided at the outlet of the water pump, one end of the delivery pipe is located inside the spray box, and one end of the delivery pipe is connected to a connecting pipe, and one end of each of the two connecting pipes is provided with a nozzle.
[0011] Preferably, the two nozzles are located on both sides of the clamping mechanism.
[0012] Preferably, rectangular blocks are provided on both sides of the inside of the spray box, and two spray nozzles are respectively installed on the two rectangular blocks.
[0013] The advantages of this utility model are: 1. This utility model, by setting a conical block mechanism driven by a threaded rod, can synchronously control the opposite or reverse movement of two rectangular bars and clamping plates, realizing flexible and stepless adjustment of the clamping distance. It can quickly adapt to bearing outer rings of various diameters. Moreover, through the contact between the conical surface and the inclined surface of the rectangular bar, the rotational force is smoothly converted into a horizontal linear clamping force. The clamping process is stable, effectively avoiding scratches or deformations on the precision surface of the bearing caused by impact or excessive clamping, and ensuring the integrity of the workpiece.
[0014] 2. The clamping mechanism of this utility model is directly connected to the drive source, which can stably drive the outer ring of the bearing to rotate at a uniform speed. Combined with the spray nozzles symmetrically distributed on both sides of the workpiece, it realizes synchronous, bidirectional, circumferential spraying of the bearing outer ring, completely eliminating the shadow effect and uneven thickness problems caused by single-sided spraying, ensuring uniform coverage of the buffer coating on all aspects of the bearing outer ring, and significantly improving the impact resistance and durability of the product.

[0018] 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 scope of protection of the present utility model.
[0019] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail. This application discloses a spraying apparatus for an impact-resistant bearing buffer layer. (See also...) Figure 1 , Figure 2 , Figure 3 and Figure 4A spraying device for an impact-resistant bearing buffer layer includes a spraying box 1 and a clamping mechanism 6. The spraying box 1 serves as the main structure and sealed working chamber of the entire device, housing all core components such as drive, clamping, and spraying. A drive source 5 is located on the rear side of the interior of the spraying box 1, and a bearing support 501 is located at the bottom of the interior of the spraying box 1. The output end of the drive source 5 is mounted on the bearing support 501. The drive source 5 (usually a motor) is the source of rotational power, and its output end provides stable support and transmits torque through the bearing support 501. The clamping mechanism 6 includes a mounting cylinder 601, which is the base of the clamping mechanism 6 and is used to house and mount all clamping parts. One end of the mounting cylinder 601 has a rotating rod 602, which is connected to the output end of the drive source 5. The rotating rod 602 is the interface for power input. Sliding holes 603 are respectively provided in the upper and lower parts of the mounting cylinder 601. The interior of the 3 is fitted with rectangular bars 605. The sliding hole 603 provides a channel for the linear motion of the rectangular bars 605. One end of each of the two rectangular bars 605 is provided with a clamping plate 607. The clamping plate 607 is a component that directly contacts and fixes the workpiece (bearing outer ring 7). The other end of the mounting cylinder 601 is provided with a sealing plate 609. The sealing plate 609 closes the rear end of the mounting cylinder 601 and serves to seal and install the nut 6010. The sealing plate 609 is provided with a nut 6010. The nut 6010 is fitted with a threaded rod 6011. The nut 6010 converts the rotational motion of the threaded rod 6011 into linear motion. One end of the threaded rod 6011 is provided with a conical block 6012. The conical surface of the conical block 6012 contacts the other end of the rectangular bars 605. The conical block 6012 converts the axial thrust of the threaded rod 6011 into a radial component force acting on the two rectangular bars 605, pushing them to move outward synchronously.
[0020] Reference Figure 3 and Figure 4 The other end of the threaded rod 6011 is provided with a knob 6013. The knob 6013 and the threaded rod 6011 are the user's operation interface. Rotating the knob 6013 can drive the threaded rod 6011 forward or backward.
[0021] Reference Figure 3 and Figure 4 The sliding hole 603 has a limiting slider 604 on both sides, and the rectangular bar 605 has a limiting groove 606 on both sides. The limiting slider 604 is fitted in the limiting groove 606. The limiting slider 604 and the limiting groove 606 are an anti-rotation design, which makes the rectangular bar 605 slide strictly in a straight radial direction in the sliding hole 603, but completely restricts its own rotation or sway.
[0022] Reference Figure 3 and Figure 4Each of the two clamping plates 607 has a baffle 608 on one side. The baffle 608 is part of or an additional structure of the clamping plate 607. It increases the contact area with the workpiece and limits the workpiece from the end face to prevent it from moving axially during the rotating spraying process, thus ensuring the stability of the rotation process.
[0023] Reference Figure 1 and Figure 2 The outer clamps of the two clamping plates 607 hold the outer ring 7 of the bearing.
[0024] Reference Figure 1 and Figure 2 A storage tank 2 is provided on one side of the spray box 1. The storage tank 2 is responsible for storing liquid elastomer material. A water pump 3 is provided on the top of the storage tank 2. The water pump 3 is used to extract the paint inside the storage tank 2. A delivery pipe 301 is provided at the outlet of the water pump 3. The delivery pipe 301 is used to deliver the paint. One end of the delivery pipe 301 is located inside the spray box 1. One end of the delivery pipe 301 is connected to a connecting pipe 302. The connecting pipe 302 delivers the paint to the nozzle 303. One end of each of the two connecting pipes 302 is provided with a nozzle 303. The nozzle 303 sprays the paint for spraying.
[0025] Reference Figure 1 and Figure 2 The two nozzles 303 are located on both sides of the clamping mechanism 6.
[0026] Reference Figure 1 and Figure 2 The spray box 1 has rectangular blocks 4 on both sides inside. Two spray nozzles 303 are respectively set on the two rectangular blocks 4. The rectangular blocks 4 are used to install and fix the spray nozzles 303 to ensure that the spray nozzles 303 are firmly and accurately positioned so as to accurately align with the workpiece and optimize the spraying effect.
[0027] Working principle: The operator first places the outer ring 7 of the bearing between the two clamping plates 607, rotates the knob 6013, drives the threaded rod 6011 to move, thereby driving the tapered block 6012 at the front end to move. When the tapered block 6012 moves, the tapered surface of the tapered block 6012 contacts the ends of the two rectangular bars 605 and squeezes the two rectangular bars 605. The squeezed rectangular bars 605 will move along the sliding hole 603, driving the two clamping plates 607 to move closer to the inside of the outer ring 7 of the bearing until the outer ring 7 of the bearing is firmly clamped. The self-locking characteristic of the threaded pair can maintain the clamping force unchanged after the hand is released, and the baffle 608 limits the movement from the side to prevent the workpiece from moving axially.
[0028] After clamping, the drive source 5 is started. The power generated by the drive source 5 is transmitted to the entire clamping mechanism 6 through the output end and the rotating rod 602. The clamping mechanism 6 drives the clamped bearing outer ring 7 to start rotating at a uniform speed. At the same time, the water pump 3 is started to pump the paint in the storage tank 2 out and deliver it to two symmetrically arranged nozzles 303 through the delivery pipe 301 and the connecting pipe 302. The two nozzles 303 spray atomized paint onto the surface of the bearing outer ring 7 from both sides. Because the workpiece is rotating at a constant speed, its entire outer surface is circumferentially and uniformly exposed to the atomization range of the sprayed material, thus achieving 360° uniform spraying without dead angles.
[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
