Description

Technical Field

[0001] This utility model belongs to the technical field of spraying devices, specifically relating to a spraying device for bearing processing. Background Technology

[0002] The main reason for spraying bearings is to improve their wear resistance, corrosion resistance, and extend their service life. Spraying is a surface treatment technology that forms a protective film on the bearing surface, effectively preventing corrosive substances in the external environment from damaging the internal structure of the bearing, thereby reducing wear and corrosion and maintaining smooth operation of the bearing. Furthermore, the bearing spraying equipment can precisely control the flow rate, pressure, and temperature of the spraying material to ensure the uniformity and quality of the coating. It helps to improve the wear resistance of the bearing, reduce the coefficient of friction, extend its service life, and to a certain extent prevent the bearing from rusting or corroding in harsh environments.

[0003] Currently, although bearing spraying devices on the market can clamp the bearing surface for spraying, the claw part often obstructs the bearing surface. Common spraying devices have difficulty fixing bearings of different diameters, which may cause the bearing to shake during the spraying process, resulting in uneven coating thickness on the bearing surface and affecting the quality of bearing spraying. Utility Model Content

[0004] The purpose of this invention is to provide a spraying device for bearing processing. This device can fix the inner diameter of different bearings, ensuring that they do not shake during the bearing spraying process, thereby improving the uniformity of the spraying on the outer surface of the bearing and thus improving the quality of the bearing spraying.

[0005] The specific technical solution adopted by this utility model is as follows:

[0006] A spraying device for bearing processing includes a housing, a spray pipe installed on one side of the inner wall of the housing with the top end of the spray pipe penetrating the housing and extending upward, a plurality of spray nozzles connected sequentially along one side of the spray pipe in the vertical direction, a controller fixedly connected to one side of the front of the housing, a glass door hinged to the other side of the front of the housing, and a limit component provided inside the housing.

[0007] Preferably, the limiting component includes a rotating shaft rotatably connected to the bottom of the inner cavity of the housing. A motor is fixedly connected to the bottom of the housing, and the output end of the motor is fixedly connected to the bottom end of the rotating shaft. A turntable is fixedly connected to the top end of the rotating shaft. A base is fixedly connected to the top end of the turntable. Multiple sliding grooves are evenly distributed on the top of the base. A sliding rod is fixedly connected to one side of the inner wall of each of the multiple sliding grooves. A fixing block is fixedly connected to one end of each sliding rod, and the bottom end of the fixing block is fixedly connected to the top of the turntable. A fixing ring is slidably connected to the surface of the sliding rod. A sliding frame is fixedly connected to the top end of the fixing ring. The sliding frame is slidably disposed in the sliding groove. A first spring is fixedly connected to the side of the fixing block and the fixing ring that are close to each other, and the first spring is sleeved on the sliding rod. A connecting block is fixedly connected to the end of the sliding frame that is away from the base. A telescopic rod is fixedly connected to the bottom end of the connecting block. A manual suction cup is fixedly connected to the bottom end of the telescopic rod, and the bottom of the manual suction cup is attached to the turntable. A second spring is fixedly connected to the side of the connecting block and the manual suction cup that are close to each other, and the second spring is sleeved on the telescopic rod.

[0008] Preferably, a positioning rod is inserted on the side of the top of the sliding frame away from the chassis, and multiple sets of limiting sleeves that cooperate with the positioning rod are fixed on the top of the turntable.

[0009] Preferably, the sliding frame has an overall L-shaped structure, and the bending part of the sliding frame is fitted with an anti-slip sleeve.

[0010] Preferably, there are at least three sets of the grooves.

[0011] Preferably, each group of nozzles is equipped with a solenoid valve at the end near the nozzle pipe.

[0012] The technical effects achieved by this utility model are as follows:

[0013] This utility model discloses a bearing processing spraying device. By setting a limiting component, the elasticity of the first spring allows the sliding frame to slide freely within the slide groove, enabling rapid pulling and positioning of the inner ring according to the diameter of the bearing ring. The rebound characteristic of the second spring stretches the telescopic rod, causing the manual suction cup to adhere tightly to the turntable, allowing for rapid adsorption of the manual suction cup onto the top of the turntable. This facilitates limiting the movement of the sliding frame and ensures the stability of the bearing ring placed on the top of the chassis. This device achieves stable fixation for bearings with different inner diameters, ensuring that the bearing does not shake during spraying, thereby improving the uniformity of the spraying on the outer surface of the bearing and ultimately enhancing the quality of the bearing spraying.

[0019] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0020] like Figure 1 As shown, a spraying device for bearing processing includes a housing 1. A spray pipe 2 is installed on one side of the inner wall of the housing 1, and the top end of the spray pipe 2 passes through the housing 1 and extends upward. Multiple sets of spray nozzles 3 are connected sequentially along the vertical direction on one side of the spray pipe 2. A controller is fixedly connected to one side of the front of the housing 1, and a glass door is hinged to the other side of the front of the housing 1. A limit component is provided inside the housing 1.

[0021] Specifically, the coating material is input through the flange at the top of the spray pipe 2, and then delivered to multiple sets of nozzles 3 through the spray pipe 2. The solenoid valve is controlled by the controller. In this way, the number and position of the nozzles 3 can be manually adjusted according to the width of the bearing, so that the coating material can be evenly sprayed on the outer ring of the bearing ring according to the diameter of the bearing ring. In addition, the design of the glass door makes it easy for users to observe the internal spraying process, thereby improving the transparency and controllability of the spraying operation.

[0022] like Figure 1 - Figure 3As shown, the limiting assembly includes a rotating shaft 4 rotatably connected to the bottom of the inner cavity of the housing 1. A motor 5 is fixedly connected to the bottom of the housing 1, and the output end of the motor 5 is fixedly connected to the bottom end of the rotating shaft 4. A turntable 6 is fixedly connected to the top of the rotating shaft 4, and a base plate 7 is fixedly connected to the top of the turntable 6. Multiple sliding grooves 8 are evenly opened on the top of the base plate 7. A sliding rod 9 is fixedly connected to one side of the inner wall of each of the multiple sliding grooves 8. A fixing block 10 is fixedly connected to one end of each sliding rod 9, and the bottom end of the fixing block 10 is fixedly connected to the top of the turntable 6. A fixing ring 11 is slidably connected to the surface of the sliding rod 9, and the top end of the fixing ring 11 is fixedly connected to... A sliding frame 13 is attached, which is slidably disposed in the slide groove 8. A first spring 12 is fixedly connected to the side of the fixed block 10 and the fixed ring 11 that are close to each other, and the first spring 12 is sleeved on the slide rod 9. A connecting block 16 is fixedly connected to the end of the sliding frame 13 away from the chassis 7. A telescopic rod 17 is fixedly connected to the bottom end of the connecting block 16. A manual suction cup 18 is fixedly connected to the bottom end of the telescopic rod 17, and the bottom of the manual suction cup 18 is attached to the turntable 6. A second spring 19 is fixedly connected to the side of the connecting block 16 and the manual suction cup 18 that are close to each other, and the second spring 19 is sleeved on the telescopic rod 17.

[0023] Specifically, the output of motor 5 drives the rotation of shaft 4, which in turn drives the limiting component and bearing ring to rotate as a whole. This allows the bearing ring to evenly receive the spray material sprayed from nozzle 3 when rotating on the limiting component, thereby improving the uniformity of the coating. At the same time, the rebound effect of the first spring 12 is used to drive the sliding frame 13 to slide in the slide groove 8, ensuring that the sliding frame 13 can be effectively and securely fixed according to the inner diameter of bearings of different sizes. Then, under the elastic force of the second spring 19, the bottom of the manual suction cup 18 will contact the top of the turntable 6 in real time when it moves with the sliding frame 13. When the sliding frame 13 moves to a suitable position, the user can quickly and manually attach the manual suction cup 18 to the turntable 6, which will limit the sliding frame 13 after fixing the bearing and ensure that the bearing will not shake during the coating process, further improving the uniformity of the coating on the outer surface of the bearing.

[0024] like Figure 2 As shown, a positioning rod 14 is inserted on the top side of the sliding frame 13 away from the chassis 7, and multiple sets of limiting sleeves 15 that cooperate with the positioning rod 14 are fixed on the top of the turntable 6.

[0025] The positioning rod 14 is used in conjunction with the limiting sleeve 15 to initially tighten the multiple sliding frames 13 inward. Then, the bearing is placed on the top of the sliding frame 13. After that, the positioning rod 14 is removed. Under the elastic force of the first spring 12, the sliding frame 13 quickly fixes the bearing on the top of the chassis 7. During the spraying process, the positioning rod 14 needs to be removed from the sliding frame 13 to avoid obstructing the spray nozzle 3.

[0026] like Figure 2As shown, the sliding frame 13 has an overall L-shaped structure, and anti-slip sleeves are fitted at the bends of the sliding frame 13.

[0027] Specifically, the L-shaped structure is used to restrict the movement of the bearing rings and serves a positioning function; the anti-slip sleeve is used to protect the bearing rings and prevent wear.

[0028] like Figure 2 As shown, there are at least three sets of slides 8.

[0029] The limitation on the number of grooves 8 is designed to enable multi-directional positioning of the inner ring of the bearing ring, thereby improving the stability of the bearing ring during initial positioning.

[0030] like Figure 1 As shown, each set of nozzles 3 is equipped with a solenoid valve at one end near the nozzle pipe 2.

[0031] Specifically, the solenoid valve can control the opening and closing of the nozzle 3, so that the position and number of nozzles 3 can be freely selected according to the size of the bearing ring.

[0032] The working principle of this utility model is as follows: The initial state of the sliding frame 13 is in an inwardly contracted state, the first spring 12 is in a stretched state, and at this time, the positioning rod 14 is in the limit sleeve 15 insertion state. At this time, the user places the bearing ring on the sliding frame 13, and then pulls out the positioning rod 14. At this time, the elastic rebound of the first spring 12 causes the sliding frame 13 to move outward until the vertical bend of the sliding frame 13 contacts the inner ring of the bearing and performs preliminary positioning of its inner ring. Under the elastic force of the second spring 19, the manual suction cup 18 moves with the sliding frame 13. The bottom of the manual suction cup 18 will be in constant contact with the top of the turntable 6. When the sliding frame 13 moves to the appropriate position, the user can quickly and manually attach the manual suction cup 18 to the turntable 6 to limit the movement of the sliding frame 13 and prevent it from shaking during bearing spraying. After that, the user closes the glass door and uses an external spraying device to deliver paint through the spray pipe 2 into the nozzle 3. At this time, the user drives the motor 5 through the controller. The motor 5 drives the bearing ring to rotate with the help of the turntable 6. The paint sprayed from the nozzle 3 can then fully coat the rotating bearing ring.

[0033] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
