Description

Technical Field

[0001] This utility model relates to the field of bearing ring processing technology, specifically a cleaning device for bearing ring processing. Background Technology

[0002] Bearing rings are one of the core components of a bearing, and their machining quality directly affects the bearing's precision, lifespan, and performance. They are commonly made of high-carbon chromium bearing steel, carburized steel, or stainless steel. The process involves sawing, forging, or bar cutting to form a ring-shaped blank, heating it to 1100-1200°C, and then forging it to refine the grains, improve mechanical properties, eliminate forging stress, and improve machinability. Rough turning forms the initial shape, and finish turning ensures dimensional accuracy. Quenching and low-temperature tempering improve hardness and wear resistance. Carburizing heat treatment, suitable for low-carbon steel, hardens the surface. Fine grinding is a critical process to ensure dimensional accuracy. Cleaning removes grinding oil and provides rust prevention. The cleaning device for bearing ring machining is a specialized piece of equipment used to remove residual cutting oil, metal shavings, dust, scale, and other contaminants from turning, grinding, and heat treatment processes, ensuring the cleanliness of the rings before assembly meets industry standards.

[0003] In some existing bearing ring cleaning devices, the bearing rings are fixed on the upper end of a fixture, then placed inside a cleaning tank containing cleaning fluid, and then cleaned by ultrasonic waves.

[0004] Existing cleaning devices for bearing ring processing have the following problems: when cleaning bearing rings, the fixture can only hold bearing rings of a single size. When bearing rings of different sizes are present, the fixture needs to be changed, which wastes time and reduces the efficiency of bearing ring cleaning. Therefore, we propose a cleaning device for bearing ring processing. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide a cleaning device for bearing ring processing. When cleaning bearing rings, the fixture can hold bearing rings of different sizes without the need to change the fixture, thus avoiding wasting time and improving the working efficiency of cleaning bearing rings. This can effectively solve the problems in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a cleaning device for processing bearing rings, comprising a cleaning table, a cleaning pool at the upper end of the cleaning table, a vibrating steel plate at the lower end of the cleaning pool, ultrasonic transducers evenly distributed at the lower end of the vibrating steel plate, a support frame at the upper end of the cleaning pool, a cover plate in the middle of the support frame, and evenly distributed brackets at the lower end of the cover plate, and also includes a clamping mechanism.

[0007] Clamping mechanism: It includes a support cylinder, a circular cylinder, a support rod, and an arc-shaped support plate. The lower end of the bracket is provided with a support cylinder, and a circular cylinder is provided in the circular hole on the outer surface of the support cylinder. The support rod is slidably connected inside the circular cylinder, and the opposite ends of the support rod are fixedly connected with arc-shaped support plates. When cleaning bearing rings, the clamp can clamp bearing rings of different sizes without the need to change the clamp, avoiding wasting time and improving the work efficiency of cleaning bearing rings.

[0008] Furthermore, an ultrasonic generator is provided at the right end of the cleaning station, and a control switch group is provided at the rear of the upper end of the ultrasonic generator. The input end of the control switch group is electrically connected to an external power source, and the input ends of the ultrasonic transducers are all electrically connected to the output ends of the ultrasonic generator. The input ends of the ultrasonic generator are electrically connected to the output ends of the control switch group, providing electrical connections for each electrical component.

[0009] Furthermore, the clamping mechanism also includes trapezoidal blocks, internal threaded cylinders, trapezoidal push blocks, and threaded rods. Trapezoidal blocks are fixedly connected to the opposite ends of the support rods. The sliding grooves on the inner wall of the support cylinder are slidably connected to the sliding strips on the outer wall of the adjacent internal threaded cylinders. Evenly distributed trapezoidal push blocks are fixedly connected to the outer surfaces of the internal threaded cylinders. The inclined surfaces of the trapezoidal blocks are slidably connected to the inclined surfaces of adjacent trapezoidal push blocks located inside the same support cylinder. Threaded rods are rotatably connected to the front walls of the support cylinders. The threaded rods are threadedly connected to the internal threaded cylinders located inside the same support cylinder, providing a rotatable connection.

[0010] Furthermore, the clamping mechanism also includes springs, and springs are respectively fitted on the outer wall of the support rod between the inner wall of the support cylinder and the opposite ends of the trapezoidal block located inside the same support cylinder, so as to facilitate rebound.

[0011] Furthermore, the front end of the support cylinder is rotatably connected to an inner four-corner cylindrical head via a sealed bearing, and the front end of the threaded rod is fixedly connected to the rear end of the longitudinally adjacent inner four-corner cylindrical head. An adjusting wrench is provided on the outside of the cleaning table, and the adjusting wrench is installed in conjunction with the inner four-corner cylindrical head for easy adjustment.

[0012] Furthermore, the upper end of the support frame is provided with an electric push rod, the telescopic end of which is fixedly connected to the upper end of the cover plate, and the input end of the electric push rod is electrically connected to the output end of the control switch group to provide lifting drive.

[0013] Furthermore, a water pipe is provided on the upper side of the inner wall of the cleaning pool, and evenly distributed nozzles are provided on the outer surface of the water pipe. A water inlet pipe is provided at the water inlet at the left end of the cleaning pool, and a water outlet pipe is provided at the water outlet at the left end of the cleaning pool to facilitate water inflow and outflow.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This cleaning device for bearing ring processing has the following advantages:

[0015] By adjusting the wrench and the inner four-corner cylindrical head, the threaded rod and the threaded inner cylinder drive the inclined surface of the trapezoidal push block to squeeze the inclined surface of the trapezoidal block.

When cleaning bearing rings, the fixture can clamp bearing rings of different sizes without the need to change the fixture, avoiding wasted time and improving the work efficiency of cleaning bearing rings.

[0021] 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.

[0022] Please see Figure 1-4This embodiment provides a technical solution: a cleaning device for processing bearing rings, including a cleaning table 1, a cleaning pool 2 at the upper end of the cleaning table 1, a vibrating steel plate 3 at the lower end of the cleaning pool 2, uniformly distributed ultrasonic transducers 4 at the lower end of the vibrating steel plate 3, a support frame 6 at the upper end of the cleaning pool 2, a cover plate 7 in the middle of the support frame 6, and uniformly distributed brackets 8 at the lower end of the cover plate 7. It also includes a clamping mechanism 9. An ultrasonic generator 5 is located at the right end of the cleaning table 1, and a control switch group 18 is located on the rear side of the upper end of the ultrasonic generator 5. The input end of the control switch group 18 is electrically connected to an external power supply. The input ends of the ultrasonic transducers 4 are uniformly distributed... The output of the ultrasonic generator 5 is electrically connected, and the input of the ultrasonic generator 5 is electrically connected to the output of the control switch group 18. An electric push rod 13 is located on the upper end of the support frame 6. The telescopic end of the electric push rod 13 is fixedly connected to the upper end of the cover plate 7. The input of the electric push rod 13 is electrically connected to the output of the control switch group 18. A water pipe 14 is located on the upper side of the inner wall of the cleaning tank 2. Evenly distributed nozzles 15 are located on the outer surface of the water pipe 14. An inlet pipe 16 is located at the water inlet at the left end of the cleaning tank 2, and an outlet pipe 17 is located at the water outlet at the left end of the cleaning tank 2. Then, through the control switch group 18, the electric push rod 13 operates, and the telescopic end of the electric push rod 13 extends... The extended drive cover plate 7 and the clamping mechanism 9 below it descend, completely immersing the clamped bearing rings in the cleaning fluid in the cleaning tank 2 (the cleaning fluid is pre-injected through the water inlet pipe 16). Then, the ultrasonic generator 5 operates, converting electrical energy into a high-frequency electrical signal, which is transmitted to the ultrasonic transducer 4 at the lower end of the vibrating steel plate 3. The ultrasonic transducer 4 converts the electrical signal into high-frequency mechanical vibration, which is transmitted to the cleaning fluid through the vibrating steel plate 3 and the bottom wall of the cleaning tank 2. This causes the liquid to generate a large number of tiny bubbles. When the bubbles rapidly collapse, they release instantaneous impact force, peeling away iron filings, oil stains, and other contaminants from the surface, grooves, and inner holes of the bearing rings. After cleaning for a certain period of time... By adjusting the control switch group 18, the ultrasonic generator 5 stops operating, the electric push rod 13 operates, and the telescopic end of the electric push rod 13 pulls the cover plate 7 upward, which drives the bearing ring through the bracket 8 and the clamping mechanism 9 to a position at the horizontal line of the nozzle 15. Then, the water pipe 14 is connected to an external cleaning water source with a certain water pressure (an external water pump can also be connected) to ensure that the nozzle 15 can spray water normally, thereby spraying and rinsing the surface of the bearing ring, washing away the dirt stripped by the ultrasonic waves in time to avoid secondary adhesion. The waste liquid after cleaning is discharged through the water outlet pipe 17 (a butterfly valve of existing technology can be installed at the water outlet pipe 17), completing one cleaning cycle.

[0023] Clamping mechanism 9: It includes a support cylinder 91, a circular cylinder 92, a support rod 93, and an arc-shaped support plate 94. The lower end of the bracket 8 is provided with a support cylinder 91. A circular cylinder 92 is provided in a circular hole on the outer surface of the support cylinder 91. The support rod 93 is slidably connected inside the circular cylinder 92. The opposite ends of the support rod 93 are fixedly connected with the arc-shaped support plate 94. (A rubber corrugated sleeve can be provided between the inner arc surface of the arc-shaped support plate 94 and the edge of the outer surface of the adjacent circular cylinder 92, so that the rubber corrugated sleeve is respectively fitted on the outside of the support rod 93 extending outside the support cylinder 91. The rubber corrugated sleeve prevents cleaning fluid from seeping into the interior of the support cylinder 91 and protects the connecting parts inside the support cylinder 91.) The clamping mechanism 9 also includes a trapezoidal block 96, an internally threaded cylinder 97, and a trapezoidal push block. 98 and threaded rod 99, trapezoidal blocks 96 are fixedly connected to the opposite ends of support rod 93, sliding grooves on the inner wall of support cylinder 91 are slidably connected to the slide strips on the outer wall of adjacent internal threaded cylinder 97, evenly distributed trapezoidal push blocks 98 are fixedly connected to the outer surface of internal threaded cylinder 97, the inclined surfaces of trapezoidal blocks 96 are slidably connected to the inclined surfaces of adjacent trapezoidal push blocks 98 located inside the same support cylinder 91, threaded rods 99 are rotatably connected to the front wall of support cylinder 91, threaded rods 99 are threadedly connected to internal threaded cylinders 97 located inside the same support cylinder 91, clamping mechanism 9 also includes springs 95, springs 95 are sleeved on the outer wall of support rod 93 between the inner wall of support cylinder 91 and the opposite ends of trapezoidal blocks 96 located inside the same support cylinder 91. 5. (Spring 95 needs to be replaced periodically to prevent aging and loss of elasticity. When spring 95 needs to be replaced, the entire clamping mechanism 9 should also be replaced.) The front end of the support cylinder 91 is rotatably connected to an inner quadrangular cylindrical head 11 via a sealed bearing 10. The front end of the threaded rod 99 is fixedly connected to the rear end of the longitudinally adjacent inner quadrangular cylindrical head 11. An adjusting wrench 12 is provided on the outside of the cleaning table 1. The adjusting wrench 12 is installed in conjunction with the inner quadrangular cylindrical head 11. (The outer surface of the outer ring of the sealed bearing 10 is fixedly connected to the inner wall of the clearance hole at the front end of the support cylinder 91, and the inner wall of the inner ring of the sealed bearing 10 is fixedly connected to the outer wall of the inner quadrangular cylindrical head 11. The sealed bearing 10 prevents cleaning fluid from leaking from the adjustment part.) The outside of the cleaning table 1 An adjusting wrench 12 is provided, which is installed in conjunction with the inner square cylindrical head 11. When cleaning the bearing rings, the electric push rod 13 is operated by controlling the control switch group 18. The telescopic end of the electric push rod 13 will drive the cover plate 7 to move upward, which in turn will drive the support cylinder 91 to move upward through the bracket 8. Then, the bearing rings are placed on the upper end of the upper arc-shaped support plate 94. Next, the adjusting wrench 12 is inserted into the insertion hole at the front end of the inner square cylindrical head 11. Then, the adjusting wrench 12 is rotated, which will drive the threaded rod 99 to rotate through the inner square cylindrical head 11. The inner threaded cylinder 97 moves axially through the sliding groove of the slide bar and the support cylinder 91. The trapezoidal push block 98 on the inner threaded cylinder 97 moves backward accordingly.The inclined surface of trapezoidal push block 98 slides into contact with the inclined surface of trapezoidal block 96, pushing trapezoidal block 96 to drive support rod 93 to extend and retract radially along cylindrical cylinder 92. At this time, spring 95 is compressed, and arc-shaped support plate 94 at the end of support rod 93 opens simultaneously, achieving stable clamping of bearing rings of different sizes (clamping the bearing rings on the outside of each support cylinder 91 in sequence). Then, the adjusting wrench 12 is inserted into the insertion hole at the front end of the inner four-corner cylindrical head 11, and then the adjusting wrench 12 is rotated counterclockwise. The adjusting wrench 12 will cause the inner threaded cylinder 97 to move the trapezoidal push block 98 forward through the inner four-corner cylindrical head 11 and threaded rod 99. The inclined surface of trapezoidal push block 98 disengages from the inclined surface of trapezoidal block 96. At this time, spring 95 rebounds, and arc-shaped support plate 94 at the end of support rod 93 retracts simultaneously. Then, the bearing ring is removed.

[0024] The working principle of the bearing ring cleaning device provided by this utility model is as follows: When cleaning the bearing rings, the electric push rod 13 is operated by adjusting the control switch group 18. The telescopic end of the electric push rod 13 will drive the cover plate 7 to move upward, which in turn will drive the support cylinder 91 to move upward through the bracket 8. Then, the bearing rings are placed on the upper end of the upper arc-shaped support plate 94. Next, the adjusting wrench 12 is inserted into the insertion hole at the front end of the inner four-corner cylindrical head 11. Then, the adjusting wrench 12 is rotated, which will drive the threaded rod 99 to rotate through the inner four-corner cylindrical head 11. The inner threaded cylinder 97 moves axially through the sliding groove of the slide bar and the support cylinder 91. The trapezoidal push block 98 on the inner threaded cylinder 97 moves accordingly. The device moves backward, and the inclined surface of the trapezoidal push block 98 slides into contact with the inclined surface of the trapezoidal block 96, pushing the trapezoidal block 96 to drive the support rod 93 to extend and retract radially along the circular cylinder 92. At this time, the spring 95 is compressed, and the arc-shaped support plate 94 at the end of the support rod 93 opens synchronously, realizing stable clamping of bearing rings of different sizes (clamping the bearing rings on the outside of each support cylinder 91 in sequence). Then, through the control switch group 18, the electric push rod 13 operates, and the extension end of the electric push rod 13 extends, causing the cover plate 7 and the clamping mechanism 9 below to descend, so that the clamped bearing rings are completely immersed in the cleaning fluid in the cleaning tank 2 (the cleaning fluid is pre-injected through the water inlet pipe 16). Then, the ultrasonic generator 5 operates, and the ultrasonic generator 5 converts electrical energy into high-frequency electrical signals. The ultrasonic transducer 4, located at the lower end of the vibrating steel plate 3, converts the electrical signal into high-frequency mechanical vibration. This vibration is transmitted through the vibrating steel plate 3 and the bottom wall of the cleaning tank 2 to the cleaning fluid, causing the fluid to generate a large number of tiny bubbles. When these bubbles rapidly collapse, they release instantaneous impact force, peeling away iron filings, oil stains, and other contaminants from the surface, grooves, and inner holes of the bearing rings. After a certain cleaning time, the ultrasonic generator 5 stops operating by adjusting the control switch group 18, and the electric push rod 13 operates. The telescopic end of the electric push rod 13 pulls the cover plate 7 upward, which, through the bracket 8 and clamping mechanism 9, moves the bearing rings to a position level with the nozzle 15. Then, the water pipe 14 is connected to an external cleaning water source with a certain water pressure (an external water pump can also be connected). To ensure that the nozzle 15 can spray water normally, the surface of the bearing ring will be sprayed and rinsed to remove the dirt removed by the ultrasonic waves and prevent secondary adhesion. The waste liquid after cleaning is discharged through the water outlet pipe 17 (a butterfly valve of existing technology can be installed at the water outlet pipe 17). After completing one cleaning cycle, the adjusting wrench 12 is inserted into the insertion hole at the front end of the inner four-corner cylindrical head 11. Then, the adjusting wrench 12 is turned counterclockwise. The adjusting wrench 12 will cause the inner threaded cylinder 97 to move forward through the inner four-corner cylindrical head 11 and the threaded rod 99, which will drive the trapezoidal push block 98 forward. The inclined surface of the trapezoidal push block 98 will disengage from the inclined surface of the trapezoidal block 96. At this time, the spring 95 will rebound, and the arc-shaped support plate 94 at the end of the support rod 93 will retract synchronously. Then, the bearing ring is removed.

[0025] It is worth noting that the ultrasonic generator 5 and the electric push rod 13 disclosed in the above embodiments can be either CS-4000 or SM-38STG-1000N. The control switch group 18 is provided with switch buttons that correspond one-to-one with the ultrasonic generator 5 and the electric push rod 13 and are used to control their switching operation.
