Description

Technical Field

[0001] The present invention relates to the technical field of bearing manufacturing, and particularly relates to a double inner ring bearing cleaning device. Background Art

[0002] As shown in the instruction manual appendix Figure 1 Some bearings include two inner rings. During the assembly process of such bearings, the clearance needs to be measured. Since during the production and measurement processes, the parts will carry impurities such as iron filings, before installing the brake ring, the parts need to be cleaned and then the final assembly operation is completed. The existing cleaning equipment all performs cleaning work on the surface of the entire bearing, but it is very difficult to clean the impurities attached to the gap between the two inner rings, resulting in incomplete cleaning and affecting the later use of the bearing. Summary of the Invention

[0003] The purpose of the present invention is to provide a double inner ring bearing cleaning device. After the rubber extrusion ring is extruded, it closely adheres to the two inner rings of the bearing, which can drive the two inner rings to move away from each other; through high-pressure cleaning liquid, the gap can be flushed, so that the gap between the two inner rings can be flushed;

[0004] Through the inner and outer ring cleaning mechanism, the outer surface of the bearing can be flushed, which can effectively improve the bearing cleaning quality.

[0005] The above technical purpose of the present invention is achieved through the following technical solutions:

[0006] A double inner ring bearing cleaning device includes a cleaning platform fixed on a frame. Above the cleaning platform, there are an inner ring gap cleaning mechanism and an inner and outer ring cleaning mechanism;

[0007] A circular convex platform is formed on the cleaning platform; the inner ring gap cleaning mechanism includes an upper stepped mandrel with a large upper part and a small lower part and a lower stepped mandrel with a small upper part and a large lower part. Grooves are formed at the small ends of the upper stepped mandrel and the lower stepped mandrel near the corresponding stepped surfaces. A rubber extrusion ring is sleeved in the grooves, and the outer wall of the rubber extrusion ring is higher than the outer walls of the large ends of the upper stepped mandrel and the lower stepped mandrel;

[0008] The small ends of the upper stepped mandrel and the lower stepped mandrel are respectively inserted into the corresponding extrusion sleeves, and the end surfaces of the extrusion sleeves press against the corresponding rubber extrusion rings; the extrusion sleeves are formed with first convex platforms, and the first convex platforms of the two extrusion sleeves are inserted into both ends of the spraying sleeve, and a plurality of spraying holes are formed in the middle of the spraying sleeve;

[0009] The first convex platform is formed with stepped through holes. The two stepped through holes are symmetrically arranged. The large-end holes of the two stepped through holes are respectively inserted and sleeved at both ends of the isolation sleeve. A push rod is sleeved in the small-end holes of the two stepped through holes. One end of the push rod is fixedly connected to the telescopic rod of the first telescopic cylinder fixed inside the upper stepped core shaft. The other end of the push rod is inserted and fixed inside the lower stepped core shaft.

[0010] The injection sleeve, the two extrusion sleeves and the isolation sleeve enclose a high-pressure cleaning liquid cavity, and the high-pressure cleaning liquid cavity is connected with a cleaning liquid inlet mechanism; the isolation sleeve, the push rod and the two stepped through holes enclose a hydraulic cavity, and the hydraulic cavity is connected with a hydraulic oil inlet and outlet mechanism.

[0011] A stepped sleeve is fixed at the upper end of the upper stepped core shaft. The stepped sleeve is inserted and sleeved on the piston rod of the second telescopic cylinder. A stop block is fixed at the end of the piston rod of the second telescopic cylinder. The stop block is inserted and sleeved in the large-end hole of the stepped sleeve; the second telescopic cylinder is fixed on the machine frame.

[0012] The first telescopic cylinder and the second telescopic cylinder are controlled by a controller.

[0013] Through the above technical solution, the bearing workpiece to be cleaned is placed on the circular convex platform. Then, the telescopic rod of the second telescopic cylinder extends downward, and the stepped sleeve automatically moves downward, thereby driving the upper stepped core shaft, the lower stepped core shaft, etc. to move downward. The lower stepped core shaft is inserted into the middle of the bearing workpiece, and there is a certain gap between the bottom of the lower stepped core shaft and the circular convex platform.

[0014] Then, the hydraulic oil inlet and outlet mechanism pumps hydraulic oil into the hydraulic cavity. The hydraulic oil in the hydraulic cavity pushes the two extrusion sleeves towards the corresponding upper stepped core shaft or lower stepped core shaft direction; the extrusion sleeves extrude the rubber extrusion rings. The two rubber extrusion rings bulge outwards and tightly adhere to the two inner rings of the bearing workpiece. At this time, the two inner rings, the two extrusion sleeves, the two rubber extrusion rings and the injection sleeve enclose a first cavity.

[0015] Then, the telescopic rod of the first telescopic cylinder extends, and the lower stepped core shaft is pushed away from the upper stepped core shaft through the push rod, so that the upper stepped core shaft and the lower stepped core shaft move away from each other. The upper stepped core shaft and the lower stepped core shaft drive the corresponding rubber extrusion rings to move. The rubber extrusion rings drive the two inner rings to move away from each other through the friction force with the inner rings, and a gap is formed between the two inner rings.

[0016] Then, the cleaning liquid inlet mechanism pumps the cleaning liquid into the high-pressure cleaning cavity. The cleaning liquid in the high-pressure cleaning cavity enters the first cavity through the injection holes. The cleaning liquid in the first cavity sprays out through the gap between the two inner rings and passes through the two rows of rollers, and the cleaning liquid thus completes the cleaning work of the joint of the bearing inner ring and the cleaning work of the area between the outer ring and the inner ring of the bearing workpiece and the rollers.

[0017] The present invention is further configured such that: a circle of first hemispherical tops is fixed on the cleaning platform, and the first hemispherical tops are located on the right side of the circular convex platform;

[0018] The inner and outer ring cleaning mechanism includes a lifting seat, and a circle of second hemispherical tops is fixed on the bottom surface of the lifting seat;

[0019] A sunken hole with an open lower side is formed in the middle of the lifting seat, and an inner ring spray washing part is sleeved in the sunken hole. A second cleaning liquid cavity is formed in the inner ring spray washing part, and a plurality of second liquid spraying holes are formed at the outer edge of the second cleaning liquid cavity and are arranged obliquely downward; the second cleaning liquid cavity is connected with a second liquid inlet pipe. The inner ring spray washing part is fixed at the end of the telescopic rod of a third telescopic cylinder, the third telescopic cylinder is fixed on the lifting seat, and the lifting seat is fixed at the end of the telescopic rods of two fourth telescopic cylinders;

[0020] An outer ring spray washing part is arranged outside the lifting seat, and the outer ring spray washing part is in the shape of an inverted bucket; a horizontal cavity and a vertical cavity which communicate with each other are formed in the outer ring spray washing part. A plurality of third liquid spraying holes which are circumferentially and uniformly distributed are formed on the bottom surface of the horizontal cavity, and a plurality of fourth liquid spraying holes which are circumferentially and uniformly distributed and are arranged obliquely downward and inward are formed at the lower end of the vertical cavity; the outer ring spray washing part is fixed at the end of the telescopic rods of two fifth telescopic cylinders; the vertical cavity is connected with a third liquid inlet pipe;

[0021] The fourth telescopic cylinder and the fifth telescopic cylinder are fixed on the machine frame.

[0022] The second liquid inlet pipe and the third liquid inlet pipe are connected with a pump body, and electromagnetic valves are respectively arranged on the second liquid inlet pipe and the third liquid inlet pipe. The electromagnetic valves are electrically connected with the controller.

[0023] Through the above technical solution, the bearing cleaned by the inner ring cleaning mechanism is transferred to a plurality of first hemispherical tops by a manipulator or other clamping and transferring devices;

[0024] Then the fourth telescopic cylinder drives the lifting seat to move downward. The lifting seat drives a circle of second hemispherical tops to move downward and press against the inner ring of the bearing. The two inner rings of the bearing can be closely attached together by the first hemispherical tops and the second hemispherical tops, so as to prevent impurities from entering the joint of the two inner rings during the subsequent cleaning process;

[0025] Then the third telescopic cylinder and the fifth telescopic cylinder work, the third telescopic cylinder drives the inner ring spraying part to move down and insert into the inner ring, the cleaning liquid is pumped into the second cleaning chamber from the second liquid inlet pipe through the corresponding pump, and then the cleaning liquid in the second cleaning chamber is sprayed to the inner ring through multiple second liquid spray holes, so as to spray the inner ring; at the same time, the fifth telescopic cylinder drives the outer ring spraying part to move down, when the lower end of the outer ring spraying part is close to the bearing workpiece, the cleaning liquid enters the vertical cavity from the third liquid inlet pipe through the corresponding pump, so that the cleaning liquid fills the vertical cavity and the horizontal cavity, and the cleaning liquid is sprayed out from the third spray hole and the fourth spray hole, the cleaning liquid sprayed from the third spray hole is sprayed into the area between the outer ring and the inner ring of the bearing and cleans the area, and the cleaning liquid sprayed from the fourth spray hole mainly cleans the outer ring of the bearing. After the cleaning is completed, the supply of the cleaning liquid is closed by the solenoid valve, and then the lifting seat, the inner ring spraying part, and the outer ring spraying part are moved up and reset, so as to complete the cleaning of the bearing workpiece.

[0026] The present invention is further configured as follows: the upper step mandrel is formed with an I-shaped hole; the first boss of the upper extrusion sleeve is formed with a liquid through hole that runs through from top to bottom, and the liquid through hole is communicated with the high-pressure cleaning liquid chamber;

[0027] The cleaning liquid inlet mechanism includes a first liquid inlet pipe and a liquid through pipe which are inserted and fixed at both ends of the "I"-shaped hole, the lower end of the liquid through pipe is inserted in the liquid through hole, a first sealing ring is arranged between the liquid through pipe and the liquid through hole, and the first sealing ring is inserted in the upper end of the liquid through hole. The first liquid inlet pipe is connected to a pump, and a solenoid valve is arranged on the first liquid inlet pipe, and the solenoid valve is electrically connected to the controller.

[0028] Through the above technical solution, when the two inner rings are pushed apart by the rubber extrusion ring, the solenoid valve opens, and the pump body allows the cleaning liquid to enter the high-pressure cleaning chamber through the first liquid inlet pipe. When the cleaning is completed, the solenoid valve closes the passage of the first liquid pipe.

[0029] The present invention is further configured as follows: a plug hole is formed at the lower end of the push-pull rod, an axial oil inlet and outlet hole is formed on the bottom surface of the plug hole, and a radial oil inlet and outlet hole connecting the axial oil inlet and outlet hole and the hydraulic chamber is formed in the middle of the push-pull rod;

[0030] The hydraulic oil inlet and outlet mechanism comprises a connecting sleeve inserted and fixed in the middle of the circular boss and a tension spring arranged in the hydraulic cavity; the end of the connecting sleeve whose upper end is higher than the circular boss is inserted in the insertion hole, the lower end of the connecting sleeve is connected to an oil pipe, the other end of the oil pipe is connected to the second solenoid valve, and the second solenoid valve is also connected to an oil inlet pipe and an oil return pipe;

[0031] The two ends of the tension spring are respectively fixed on the step surfaces of the two step through holes.

[0032] The oil inlet pipe and the oil return pipe are connected to the hydraulic station, and the second solenoid valve is electrically connected to the controller.

[0033] Through the above technical solution, when the telescopic rod of the second telescopic cylinder extends to drive the lower step mandrel to move downward, the insertion hole of the push-pull rod on the lower step mandrel is inserted into the connecting sleeve, and then the solenoid valve works to open the path between the oil inlet pipe and the oil through pipe. The hydraulic station pumps out hydraulic oil, and the hydraulic oil sequentially passes through the oil inlet pipe, the second solenoid valve, the oil through pipe, the insertion hole, the axial oil inlet and outlet hole, and the radial oil inlet and outlet hole and then enters the hydraulic cavity. As the hydraulic oil in the hydraulic cavity increases, the two extrusion sleeves are pushed away from each other, and the extrusion sleeves apply pressure to the rubber extrusion ring to make it bulge and deform outward. The rubber extrusion ring abuts against the inner wall of the corresponding inner ring;

[0034] When the cleaning is completed, the solenoid valve cuts off the path between the oil inlet pipe and the oil through pipe, opens the path between the oil through pipe and the oil return pipe, and the two extrusion sleeves are reset by the action of the tension spring, and the hydraulic oil in the hydraulic cavity returns to the hydraulic station through the oil return pipe.

[0035] The present invention is further arranged as follows: A plurality of circumferentially evenly distributed positioning rods are arranged on the outer side of the circular convex platform. The plurality of positioning rods pass through the lower extending end of the cleaning platform and are fixed on the lifting ring plate. The lifting ring plate is on the cylinder body of the sixth telescopic cylinder, and the telescopic rod of the sixth telescopic cylinder is fixedly connected with the circular convex platform;

[0036] A guiding conical part is formed at the upper end of the positioning rod.

[0037] Through the above technical solution, when the manipulator or the clamping and transferring device places the bearing workpiece on the anti-theft circular convex platform, the sixth telescopic cylinder drives the lifting ring plate to move upward, the lifting ring plate drives the plurality of positioning rods to move upward, and the positioning cylinder surrounds the bearing workpiece, thereby limiting the bearing workpiece within a certain range, which is convenient for the insertion work of the lower step mandrel.

[0038] The present invention is further arranged as follows: A lifting baffle is sleeved on the cleaning platform, and the lifting baffle is located at the middle position between the circular convex platform and the first hemispherical top in a circle;

[0039] A rack is formed on the lifting baffle, and a driving gear is engaged with the lower end of the rack. The driving gear is fixed on the motor shaft of the second motor, and the second motor is fixedly connected with the cleaning platform.

[0040] Through the above technical solution, when the bearing workpieces on the circular convex platform and the first hemispherical top in a circle are being cleaned, the lifting baffle is in the upward moving state, which can reduce the mutual influence of the cleaning work of the two bearing workpieces. After the cleaning is completed, the second motor drives the driving gear to rotate, and the driving gear drives the lifting baffle to move downward through the rack, which is convenient for the bearing workpiece on the circular convex platform to be transferred to the first hemispherical top in a circle.

[0041] The present invention is further arranged as follows: A plurality of water drainage holes are formed on the cleaning platform, and a cleaning liquid confluence box is fixed at the bottom of the cleaning platform.

[0042] Through the above technical solution, the cleaning liquid and impurities after cleaning the bearing workpiece enter the cleaning liquid confluence box through the water dropping holes for collection, and the cleaning liquid can be used to clean the bearing workpiece again after filtration later.

[0043] The present invention is further configured as: an annular convex block is formed on the cleaning platform, and a plurality of water dropping holes, circular convex platforms and a circle of first hemispherical tops are located within the annular convex block.

[0044] Through the above technical solution, it can prevent the cleaning liquid from flowing out of the annular convex block, causing waste of the cleaning liquid, and can also ensure the dryness of the environment around the cleaning device.

[0045] The prominent effect of the present invention is:

[0046] Compared with the prior art, by squeezing the rubber extrusion ring with the extrusion sleeve, the rubber extrusion ring can be deformed and closely attached to the corresponding inner ring, thereby forming a certain sealing property, which can improve the quality of the subsequent cleaning liquid for cleaning the gap;

[0047] Through the frictional force between the extrusion rubber ring and the inner ring and the extension of the first telescopic cylinder, the two inner rings can be driven to move away from each other, facilitating the subsequent cleaning liquid to wash the impurities in the gap, and effectively improving the cleaning quality;

[0048] Through the first hemispherical top and the second hemispherical top, the two inner rings can be closely contacted to prevent impurities from entering the gap between the two inner rings when the cleaning liquid flushes the bearing surface. BRIEF DESCRIPTION OF THE DRAWINGS

Grooves 3001 are formed at the small ends of the upper stepped mandrel 301 and the lower stepped mandrel 302 near the corresponding stepped surfaces. A rubber extrusion ring 303 is sleeved in the grooves 3001, and the outer wall of the rubber extrusion ring 303 is higher than the outer walls of the large ends of the upper stepped mandrel 301 and the lower stepped mandrel 302;

[0075] The small ends of the upper stepped mandrel 301 and the lower stepped mandrel 302 are respectively inserted into the corresponding extrusion sleeves 304, and the end surfaces of the extrusion sleeves 304 are pressed against the corresponding rubber extrusion rings 303; the extrusion sleeves 304 are formed with first convex platforms 3041, and the first convex platforms 3041 of the two extrusion sleeves 304 are inserted into both ends of a spray sleeve 305, and a plurality of spray holes 3051 are formed in the middle of the spray sleeve 305;

[0076] The first convex platform 3041 is formed with a stepped through hole 3042, the two stepped through holes 3042 are symmetrically arranged, the large end holes of the two stepped through holes 3042 are respectively inserted into both ends of an isolation sleeve 306, and a push-pull rod 307 is sleeved in the small end holes of the two stepped through holes 3042. One end of the push-pull rod 307 is fixedly connected to the telescopic rod of a first telescopic cylinder 308 fixed in the upper stepped mandrel 301, and the other end of the push-pull rod 307 is inserted and fixed in the lower stepped mandrel 302;

[0077] The spray sleeve 305, the two extrusion sleeves 304 and the isolation sleeve 306 enclose a high-pressure cleaning liquid cavity 3002, and the high-pressure cleaning liquid cavity 3002 is connected to a cleaning liquid inlet mechanism 50; the isolation sleeve 306, the push-pull rod 307 and the two stepped through holes 3042 enclose a hydraulic cavity 3003, and the hydraulic cavity 3003 is connected to a hydraulic oil inlet and outlet mechanism 60;

[0078] A stepped sleeve 309 is fixed to the upper end of the upper stepped mandrel 301. The stepped sleeve 309 is inserted over the piston rod of the second telescopic cylinder 310. A stop block 311 is fixed to the end of the piston rod of the second telescopic cylinder 310. The stop block 311 is inserted into the large-end hole of the stepped sleeve 309.

Then, the telescopic rod of the second telescopic cylinder extends downward, and the stepped sleeve automatically moves downward, thereby driving the upper stepped mandrel 301, the lower stepped mandrel 302, etc. downward. The lower stepped mandrel is inserted into the middle of the bearing workpiece, and there is a certain gap between the bottom of the lower stepped mandrel and the circular convex platform.

[0081] Then, the hydraulic oil inlet and outlet mechanism pumps hydraulic oil into the hydraulic cavity.

A horizontal cavity 4071 and a vertical cavity 4072 which communicate with each other are formed in the outer ring spraying and washing part 407. A plurality of third liquid spraying holes 4073 are formed on the lower bottom surface of the horizontal cavity 4071 and are circumferentially and evenly distributed. A plurality of fourth liquid spraying holes 4074 which are arranged obliquely downward and inward are formed at the lower end of the vertical cavity 4072. The outer ring spraying and washing part 407 is fixed at the end of the telescopic rods of two fifth telescopic cylinders 408. The vertical cavity 4072 is connected with a third liquid inlet pipe.

[0088] The fourth telescopic cylinders 406 and the fifth telescopic cylinders 408 are fixed on the machine frame 10.

[0092] Then the third telescopic cylinder and the fifth telescopic cylinder work, the third telescopic cylinder drives the inner ring spraying part to move down and insert into the inner ring, the cleaning liquid is pumped into the second cleaning chamber from the second liquid inlet pipe through the corresponding pump, and then the cleaning liquid in the second cleaning chamber is sprayed to the inner ring through multiple second liquid spray holes, so as to spray the inner ring; at the same time, the fifth telescopic cylinder drives the outer ring spraying part to move down, when the lower end of the outer ring spraying part is close to the bearing workpiece, the cleaning liquid enters the vertical cavity from the third liquid inlet pipe through the corresponding pump, so that the cleaning liquid fills the vertical cavity and the horizontal cavity, and the cleaning liquid is sprayed out from the third spray hole and the fourth spray hole, the cleaning liquid sprayed from the third spray hole is sprayed into the area between the outer ring and the inner ring of the bearing and cleans the area, and the cleaning liquid sprayed from the fourth spray hole mainly cleans the outer ring of the bearing.

[0098] Both ends of the tension spring 602 are respectively fixed on the stepped surfaces of the two stepped through holes 3042.

[0099] The inlet pipe and the return pipe are communicated with the hydraulic station, and the second solenoid valve is electrically connected to the controller.

[0100] When the telescopic rod of the second telescopic cylinder extends to drive the lower stepped mandrel 302 to move downward, the insertion hole of the push-pull rod on the lower stepped mandrel is inserted into the connecting sleeve. Then the solenoid valve works to open the path between the inlet pipe and the through pipe, and the hydraulic station pumps out the hydraulic oil. The hydraulic oil sequentially passes through the inlet pipe, the second solenoid valve, the through pipe, the insertion hole, the axial oil inlet and outlet holes, and the radial oil inlet and outlet holes and then enters the hydraulic cavity. As the hydraulic oil in the hydraulic cavity increases, the two extrusion sleeves 304 are pushed away from each other, and the extrusion sleeves apply pressure to the rubber extrusion ring to make it bulge and deform outward, and the rubber extrusion ring abuts against the inner wall of the corresponding inner ring;

[0101] When the cleaning is completed, the solenoid valve cuts off the path between the inlet pipe and the through pipe, opens the path between the through pipe and the return pipe, and the two extrusion sleeves are reset by the action of the tension spring, and the hydraulic oil in the hydraulic cavity returns to the hydraulic station through the return pipe.

[0102] A plurality of circumferentially evenly distributed positioning rods 21 are arranged on the outer side of the circular convex platform 201. The plurality of positioning rods 21 pass through the lower extending end of the cleaning platform 20 and are fixed on the lifting ring plate 22. The lifting ring plate 22 is on the cylinder body of the sixth telescopic cylinder 23, and the telescopic rod of the sixth telescopic cylinder 23 is fixedly connected to the circular convex platform 201;

[0103] A guiding conical portion 211 is formed at the upper end of the positioning rod 21.

[0104] When the manipulator or the clamping and transferring device places the bearing workpiece on the anti-theft circular convex platform, the sixth telescopic cylinder drives the lifting ring plate to move upward, the lifting ring plate drives the plurality of positioning rods to move upward, and the positioning cylinder surrounds the bearing workpiece, thereby limiting the bearing workpiece within a certain range, which is convenient for the insertion work of the lower stepped mandrel.

[0105] A lifting baffle 24 is sleeved on the cleaning platform 20, and the lifting baffle 24 is located at the middle position between the circular convex platform 201 and the first hemispherical top 202 in a circle;

[0106] A rack 241 is formed on the lifting baffle 24, and the lower end of the rack 241 meshes with a driving gear 25. The driving gear 25 is fixed on the motor shaft of the second motor 26, and the second motor is fixedly connected to the cleaning platform 20.

[0107] When the bearing workpieces on the circular boss 201 and the first hemispherical tops 202 in a circle are being cleaned, the lifting baffle is in the upward movement state, which can reduce the mutual influence of the cleaning work of the two bearing workpieces. After cleaning, the second motor drives the driving gear to rotate, and the driving gear drives the lifting baffle to move downward through the rack, facilitating the transfer of the bearing workpiece on the circular boss to the first hemispherical tops in a circle.

[0108] A number of water drainage holes 203 are formed on the cleaning platform 20, and a cleaning liquid confluence box 27 is fixed to the bottom of the cleaning platform 20.

[0109] Through the above technical solution, the cleaning liquid and impurities after cleaning the bearing workpieces enter the cleaning liquid confluence box through the water drainage holes for collection, and the cleaning liquid can be filtered and then continue to clean the bearing workpieces later.

[0110] A circular convex baffle 204 is formed on the cleaning platform 20, and a number of water drainage holes 203, the circular boss 201 and the first hemispherical tops 202 in a circle are located within the circular convex baffle 204.

[0111] Through the above technical solution, it can prevent the cleaning liquid from flowing out of the circular convex baffle, causing waste of the cleaning liquid, and can also ensure the dryness of the environment around the cleaning device.

[0112] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and modifications can be made. These improvements and modifications made under the above assumptions should also be regarded as the protection scope of the present invention.
