Description

Technical Field

[0001] This utility model relates to the technical field of ultrasonic cleaning machines for bearing processing, and specifically discloses a heating component for an ultrasonic cleaning machine for bearing processing. Background Technology

[0002] Bearings, as core supporting components of mechanical transmission systems, primarily function to support rotating shafts, reduce the coefficient of friction, and ensure the rotational accuracy of the shaft system. They are widely used in critical fields such as automobiles, CNC machine tools, industrial motors, and aerospace equipment. The machining accuracy and surface cleanliness of bearings directly determine the operational stability, transmission efficiency, and service life of the main equipment. After machining processes such as cutting, grinding, and heat treatment, contaminants such as cutting oil, metal shavings, rust-preventive grease, and emulsion residues can easily remain on the surface of the bearing, raceways, cage clearance, and inner and outer ring mating surfaces. If these contaminants are not thoroughly removed, they can not only lead to abnormal clearances between the bearing and the journal during subsequent assembly but may also accelerate bearing wear during equipment operation, causing abnormal noises, excessive temperature rise, or even shaft seizure. Therefore, bearings require efficient cleaning methods to ensure cleanliness after machining. Ultrasonic cleaning machines, with their unique "cavitation effect," have become the mainstream cleaning equipment in the bearing machining field.

[0003] In existing technologies, ultrasonic cleaning of bearings involves immersing the bearings into the cleaning tank of the ultrasonic cleaner. However, most ultrasonic cleaners for bearing processing on the market currently only have a single cleaning function and do not integrate a heating and drying mechanism. After cleaning, a large amount of moisture remains on the surface and in the crevices. To prevent moisture from causing corrosion, the bearings must be removed by the operator and transferred to a separate drying oven for heating and drying. However, manual transfer increases the number of steps and labor costs, making the operation cumbersome. Separating the cleaning and drying equipment also increases the workshop floor space and equipment investment costs.

[0004] Therefore, a heating component for an ultrasonic cleaning machine used in bearing processing is needed to solve the above problems. Utility Model Content

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0025] Please see Figure 1-5 A heating assembly for an ultrasonic cleaning machine for bearing processing includes a base plate 1, a cleaning box 2 is arranged above the base plate 1, multiple ultrasonic transducers 4 are installed at the lower end of the cleaning box 2, an ultrasonic generator 3 is installed at the upper end of the base plate 1, two mesh trays 6 are arranged inside the cleaning box 2, the two mesh trays 6 are fixedly connected by a connecting column 7, a handle is fixedly connected to the outer wall of the connecting column 7, and a positioning mechanism is arranged inside the cleaning box 2.

[0026] A heating and drying mechanism is provided above the base plate 1. The heating and drying mechanism includes a wind box 11 located on the upper side of the cleaning box 2. A sealing gasket 12 that abuts against the upper edge of the cleaning box 2 is embedded in the lower end of the wind box 11 through a groove. Multiple air outlets are connected to the lower end of the wind box 11. A mounting shell 13 is connected to the upper end of the wind box 11. A honeycomb electric heater 14 is installed inside the mounting shell 13. A fixing plate is fixedly connected to the upper end of the wind box 11. A fan 15 whose air outlet is connected to the mounting shell 13 is installed on the outer wall of the fixing plate.

[0027] An auxiliary opening and closing mechanism is provided on the right side of the air box 11. The auxiliary opening and closing mechanism includes a hydraulic cylinder 19 installed on the upper end of the base plate 1. A lifting plate 18 is provided on the right side of the cleaning box 2. A tension sensor 20 is fixedly connected between the output end of the hydraulic cylinder 19 and the lifting plate 18. A steel shaft 17 is fixedly connected to the upper end of the lifting plate 18. A movable plate 16 fixedly connected to the air box 11 is rotatably connected to the outer wall of the steel shaft 17 through a bearing. The auxiliary opening and closing mechanism also includes a locking mechanism.

[0028] In this embodiment: During use, the operator places the bearing to be cleaned inside the two mesh trays 6, ensuring they are not stacked but placed in a single layer. The mesh trays 6 are then placed into the cleaning tank 2 using the handles on the outer wall of the connecting column 7. A positioning mechanism supports and limits the two mesh trays 6. After injecting an appropriate amount of water into the cleaning tank 2, the ultrasonic generator 3 on the upper end of the base plate 1 is activated. The generated high-frequency electrical signal is transmitted to multiple ultrasonic transducers 4. The ultrasonic transducers 4 create a cavitation effect in the water within the cleaning tank 2, thoroughly cleaning the bearing inside the mesh trays 6. After cleaning is complete, the hand valve of the drain pipe 5 is opened to drain the water from the cleaning tank 2.

[0029] After the water is drained, the locking mechanism releases the limit on the movable plate 16. The bellows 11 and the movable plate 16 then rotate 180° around the steel shaft 17. At this point, the bellows 11 is directly above the cleaning tank 2, and the two limit posts 25 are aligned with the two limit holes 24. The locking mechanism then prevents the bellows 11 and the movable plate 16 from rotating. Next, the output end of the hydraulic cylinder 19 retracts, causing the lifting plate 18 to descend via the tension sensor 20. When the sealing gasket 12 of the bellows 11 abuts against the upper edge of the cleaning tank 2, the tension sensor 20 monitors the tension value. When the tension reaches a preset value, the controller stops the hydraulic cylinder 19. At this point, the contact force between the upper edge of the cleaning tank 2 and the sealing gasket 12 is just right.

[0030] Outside air is then supplied to the mounting housing 13 by the fan 15. The air is heated as it flows through the honeycomb electric heater 14 inside the housing 13. The heated air then enters the air box 11 and is blown into the bearing inside the cleaning box 2 through multiple air outlets at its lower end. The hot air comes into full contact with the residual moisture in the bearing, accelerating moisture evaporation and achieving the heating and drying process. The used hot air is then discharged from the exhaust pipe 5.

[0031] By combining the above operations, the bearing can be conveniently heated and dried after ultrasonic cleaning without having to remove it from the cleaning equipment and transfer it to a separate drying device. The operation is simple and convenient, effectively reducing the workshop floor space and equipment investment costs.

[0032] As a technical optimization of this utility model, the locking mechanism includes a top plate 21 fixedly connected to the upper end of the steel shaft 17, a sliding disk 22 slidably connected to the outer wall of the steel shaft 17 through a sliding groove and a slider, a compression spring 23 sleeved on the outer wall of the steel shaft 17 fixedly connected between the sliding disk 22 and the top plate 21, two limiting holes 24 are opened at the upper end of the movable plate 16, and two limiting posts 25 are fixedly connected to the lower end of the sliding disk 22.

[0033] In this embodiment: when the sliding disk 22 is pushed upward, the compression spring 23 is compressed, and the two limiting posts 25 are dislodged from the two limiting holes 24, thereby releasing the limitation on the movable plate 16; when the pushing force on the sliding disk 22 is released, the compression spring 23 pushes the sliding disk 22 to slide downward along the groove and slider of the steel shaft 17, so that the two limiting posts 25 at the lower end of the sliding disk 22 are inserted into the two limiting holes 24 at the upper end of the movable plate 16, thereby preventing the bellows 11 and the movable plate 16 from rotating.

[0034] As a technical optimization of this utility model, the positioning mechanism includes a support block 8 fixedly connected inside the cleaning tank 2. The outer walls of the four support blocks 8 are provided with positioning grooves 9. Four insert plates 10 are fixedly connected to the outer wall of the upper mesh disk 6. The four insert plates 10 are respectively inserted into the four positioning grooves 9.

[0035] In this embodiment: when the mesh disk 6 is placed, the four insert plates 10 located on the outer wall of the upper mesh disk 6 are respectively inserted into the four positioning slots 9. The cooperation between the insert plates 10 and the positioning slots 9 restricts the horizontal movement and rotation of the mesh disk 6 in the cleaning box 2, ensuring the stability of the mesh disk 6 and the internal bearings during ultrasonic cleaning.

[0036] As a technical optimization of this utility model, two guide sleeves are fixedly connected to the upper end of the base plate 1, and guide rods that are fixedly connected to the lifting plate 18 are slidably connected inside the two guide sleeves.

[0037] In this embodiment, by setting two guide sleeves and two guide rods, the lifting plate 18 is guided to move up and down, ensuring that the lifting plate 18 moves stably and without deviation.

[0038] As a technical optimization of this utility model, the outer wall of the cleaning tank 2 is connected to a discharge pipe 5 with a hand valve.

[0039] In this embodiment: when the hand valve of the discharge pipe 5 is opened, the water inside the cleaning tank 2 can be discharged, and air can be allowed to escape.

[0040] As a technical optimization of this utility model, a vertical plate is fixedly connected to the upper end of the base plate 1, and an operation panel and controller are installed on the outer wall of the vertical plate.

[0041] In this embodiment: the upright plate provides a mounting carrier for the operation panel and the controller; the operator inputs commands through the operation panel, and the commands are transmitted to the controller; after receiving the signal, the controller coordinates and controls the operation of the honeycomb electric heater 14, the fan 15, and the hydraulic cylinder 19 according to the preset program or real-time feedback.

[0042] As a technical optimization of this utility model, the sealing gasket 12 is made of fluororubber.

[0043] In this embodiment, the sealing gasket 12 is made of fluororubber, which has the characteristics of high temperature resistance, aging resistance and good elasticity, thus improving its service life.

[0044] The working principle and usage process of this utility model are as follows: During use, the operator places the bearing to be cleaned inside the two mesh trays 6. They must be placed in a single layer, not stacked. The mesh trays 6 are then placed into the cleaning tank 2 using the handles on the outer wall of the connecting column 7. The four insert plates 10 on the outer wall of the upper mesh tray 6 are then inserted into the positioning slots 9 of the four support blocks 8, thus supporting and limiting the two mesh trays 6. After injecting an appropriate amount of water into the cleaning tank 2, the ultrasonic generator 3 on the upper end of the base plate 1 is activated. The high-frequency electrical signal generated is transmitted to multiple ultrasonic transducers 4. The ultrasonic transducers 4 cause cavitation in the water inside the cleaning tank 2, thoroughly cleaning the bearing inside the mesh trays 6. After cleaning, the hand valve of the drain pipe 5 is opened to drain the water from the cleaning tank 2.

[0045] After the water is drained, the sliding plate 22 is pushed upward, compressing the compression spring 23 and causing the two limiting posts 25 to disengage from the two limiting holes 24, thus releasing the restriction on the movable plate 16. Subsequently, the bellows 11 and the movable plate 16 rotate 180° around the steel shaft 17. At this point, the bellows 11 is directly above the cleaning box 2, and the two limiting posts 25 are aligned with the two limiting holes 24. Then, the pushing force on the sliding plate 22 is released, and the compression spring 23 pushes the sliding plate 22 downward along the groove and slider of the steel shaft 17, causing the two limiting posts 25 at the lower end of the sliding plate 22 to insert into the two limiting holes 24 at the upper end of the movable plate 16, thereby preventing the bellows 11 and the movable plate 16 from rotating. Then, the output end of the hydraulic cylinder 19 is retracted, and the lifting plate 18 is lowered by the tension sensor 20. When the sealing gasket 12 of the air box 11 comes into contact with the upper edge of the cleaning box 2, the tension value is monitored by the tension sensor 20. When the tension reaches the preset value, the controller controls the hydraulic cylinder 19 to stop moving. At this time, the contact force between the upper edge of the cleaning box 2 and the sealing gasket 12 is just right.

[0046] Outside air is then supplied to the mounting housing 13 by the fan 15. The air is heated as it flows through the honeycomb electric heater 14 inside the housing 13. The heated air then enters the air box 11 and is blown into the bearing inside the cleaning box 2 through multiple air outlets at its lower end. The hot air comes into full contact with the residual moisture in the bearing, accelerating moisture evaporation and achieving the heating and drying process. The used hot air is then discharged from the exhaust pipe 5.

[0047] By combining the above operations, the bearing can be conveniently heated and dried after ultrasonic cleaning without having to remove it from the cleaning equipment and transfer it to a separate drying device. The operation is simple and convenient, effectively reducing the workshop floor space and equipment investment costs.
