Description

Technical Field

[0001] This utility model relates to the technical field of bearing cleaning machines, and in particular to a tapered roller bearing cleaning machine. Background Technology

[0002] A tapered roller bearing comprises an inner ring with tapered raceways on its outer circumferential surface, an outer ring with tapered raceways on its inner circumferential surface, tapered rollers rolling within the tapered raceways of the inner and outer rings, and a cage that evenly separates the tapered rollers and guides their rolling direction. The tapered raceway design of the inner and outer rings allows the contact force between the rollers and the raceways to be decomposed into radial and axial components, thus enabling it to withstand two loads simultaneously.

[0003] The manufacturing process of tapered roller bearings is generally as follows: 1. Material preparation: Select suitable bearing materials according to design requirements and process them, such as cutting and heat treatment; 2. Cold extrusion: Place the heat-treated bearing material into a cold press to form a conical shape, and then cut the conical blank into appropriate lengths using a cutting process; 3. Precision grinding: Precision grind the cut conical blank; 4. Assembly: Apply an appropriate amount of lubricating oil to the inner and outer rings, then evenly separate the tapered rollers using a cage, and finally install the inner and outer rings; 5. Cleaning and dust removal: Currently, ultrasonic cleaning machines are commonly used to clean and remove dust from the assembled tapered rollers to ensure a smooth bearing surface and the absence of internal impurities; 6. Lubrication and sealing: Lubricate the bearing first, then seal it; 7. Inspection and testing: Conduct various quality inspections and tests on the manufactured tapered roller bearings; 8. Packaging and storage: Pack the qualified tapered roller bearings and then place them in the designated storage area.

[0004] The existing Chinese patent with authorization announcement number CN216174846U discloses an ultrasonic cleaning machine for bearing production and processing, including a cleaning machine housing, a cleaning chamber for cleaning bearings opened in the cleaning machine housing, an equipment cavity opened in the cleaning machine housing, an ultrasonic generator installed in the equipment cavity, and a transducer installed on the lower surface of the inner wall of the cleaning cavity.

[0005] When this ultrasonic cleaning machine for bearing manufacturing is working, the high-frequency oscillation signal emitted by the ultrasonic generator is converted into high-frequency mechanical oscillation by the transducer and propagated into the cleaning medium (cleaning solvent). The ultrasonic waves radiate forward in the cleaning liquid in alternating dense and rarefaction patterns, causing the liquid to flow and generating tens of thousands of tiny bubbles with a diameter of 50-500μm. These tiny bubbles in the liquid vibrate under the influence of the sound field. These bubbles form and grow in the negative pressure zone where the ultrasonic waves propagate longitudinally, while in the positive pressure zone, when the sound pressure reaches a certain value, the bubbles rapidly increase in size and then suddenly collapse, generating shock waves when the bubbles collapse. This generates thousands of atmospheres of pressure around the bubbles, breaking down insoluble dirt and dispersing it in the cleaning liquid. When aggregated particles are coated with oil and adhere to the surface of the parts being cleaned, the oil is emulsified, and the solid particles detach, thereby achieving the purpose of cleaning the parts.

[0006] The existing technical solutions mentioned above have the following drawbacks: Although the ultrasonic cleaning machine for bearing production and processing can clean the bearings, it requires manual insertion and removal of the bearings, which is labor-intensive and has low work efficiency.

[0023] To make the technical means, creative features, objectives and effects of this utility model clearer and easier to understand, the present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0024] like Figure 1 and 3 As shown, this utility model proposes a tapered roller bearing cleaning machine, including an ultrasonic cleaner 1, a bearing housing 3, and a housing transfer device 9.

[0025] like Figure 1 and 2 As shown, in this embodiment, there are four ultrasonic cleaners 1 arranged side by side. The top surface of each ultrasonic cleaner 1 has a cleaning chamber 2. The ultrasonic cleaner 1 can use ultrasonic waves to clean the tapered roller bearing placed in the cleaning chamber 2.

[0026] like Figure 2 As shown, the bearing housing 3 includes a housing 5 and a gripping head 4 fixed to the top surface of the housing 5.

[0027] In this embodiment, the gripping head 4 includes a disk at the top and a cylinder at the bottom, with the diameter of the cylinder being smaller than the diameter of the cylinder.

[0028] In this embodiment, five bearing grooves 6 for mounting tapered roller bearings are spaced apart on the outer wall of the housing 5. The tapered roller bearings are laid flat on the bottom of the bearing grooves 6. Each opening of the bearing groove 6 is fixedly connected to a baffle 7. The height of the baffle 7 is greater than the thickness of the tapered roller bearing. The baffle 7 is used to prevent the tapered roller bearing from running out of the bearing groove 6.

[0029] In this embodiment, each baffle 7 has a row of plate openings 71 communicating with the bearing groove 6, and five rows of box openings 8 are provided on the two opposite outer side walls of the housing 5, with the box openings 8 communicating with the bearing groove 6. When the bearing housing 3 containing the tapered roller bearing is placed into the cleaning chamber 2 of the ultrasonic cleaner 1, the cleaning solvent can enter the bearing housing 3 through the plate openings 71 and the box openings 8, allowing the cleaning solvent to come into more thorough contact with the tapered roller bearing, which is beneficial for improving the cleaning effect.

[0030] like Figure 3 and 4 As shown, the gripping device is used to grip the bearing housing 3 and drive the bearing housing 3 to perform horizontal and vertical reciprocating linear motion. The gripping device includes a worktable 10, a smooth seat 17, and a vertical slide seat 31.

[0031] In this embodiment, the workbench 10 includes three supports 11 arranged side by side at intervals and a platform 12 fixedly installed on the top of the three supports 11. The supports 11 include four vertically arranged uprights 111 and crossbars 112 fixedly connected between adjacent uprights 111.

[0032] In this embodiment, a pair of flat guide rails 13 are screwed onto the top surface of the workbench 10, and a smooth seat 17 is slidably disposed above the workbench 10. Four smooth blocks 14 that slide in cooperation with the flat guide rails 13 are screwed onto the bottom surface of the smooth seat 17.

[0033] like Figure 4 and 5 As shown, a rack and pinion track 15 is provided on the top surface of the workbench 10. The rack and pinion track 15 is located between two flat guide rails 13. Side plates 16 are fixedly connected to both sides of the rack and pinion track 15. The rack and pinion track 15 is connected to the top surface of the workbench 10 by screws through the side plates 16.

[0034] like Figure 4 and 5 As shown, a seat cavity 171 is provided on the bottom surface of the smooth seat 17, and a rack through hole 18 is provided on the outer side wall of the smooth seat 17 along the length direction of the worktable 10. The rack through hole 18 is used for the rack track 15 to pass through.

[0035] like Figure 4 and 5 As shown, a smooth drive motor 19 is fixedly mounted on the top surface of the smooth seat 17. The output shaft of the smooth drive motor 19 passes through the smooth seat 17 and extends into the seat cavity 171. A main bevel gear 20 is coaxially arranged at the end of the output shaft of the smooth drive motor 19 that extends into the seat cavity 171. A main groove 21 is provided on the top wall of the seat cavity 171, and a main bearing 22 fitted on the output shaft of the smooth drive motor 19 is embedded in the main groove 21.

[0036] like Figure 4 and5 As shown, a horizontally mounted flat shaft 23 is rotatably installed inside the seat cavity 171. A driven bevel gear 24, which meshes with the main bevel gear 20, is coaxially mounted on the flat shaft 23 via a key. An output gear 25, which meshes with the rack and pinion track 15, is also coaxially mounted on the flat shaft 23 via a key. Two side grooves 26 are symmetrically formed on the side wall of the seat cavity 171, and each side groove 26 is fitted with a side bearing 27, which is respectively fitted at both ends of the flat shaft 23.

[0037] like Figure 3 and 4 As shown, four columns 28 are vertically arranged on the top surface of the smooth seat 17. The columns 28 are welded to the top surface of the smooth seat 17. The four columns 28 are respectively arranged at the four corners of the smooth seat 17. A top plate 29 is welded and fixed to the top of the four columns 28.

[0038] like Figure 3 and 4 As shown, each column 28 has a vertical guide rail 30 screwed onto its sidewall facing both sides of the worktable 10. A vertical slide block 31 is slidably mounted on each of the two columns 28 on the same side, with the two slide blocks 31 being symmetrical. A vertical slider 32, which slides along the vertical guide rail, is screwed onto the end face of the vertical slide block 31. A connecting plate 33 is fixedly connected between the two vertical slide blocks 31. A pair of cylinders 34 are fixedly mounted on the top surface of the smooth seat 17, with the top of the piston rod of the cylinder 34 connected to the bottom surface of the connecting plate 33.

[0039] like Figure 3 and 4 As shown, a mounting plate 35 is fixedly connected to the bottom of the end face of the vertical slide 31 near the ultrasonic cleaner 1. A reinforcing plate 36 is fixedly connected between the top surface of the mounting plate 35 and the side wall of the vertical slide 31. The reinforcing plate 36 is used to improve the connection strength between the mounting plate 35 and the vertical slide 31.

[0040] like Figure 2 As shown, a gripping mechanism 37 is provided on the bottom surface of the mounting plate 35. The gripping mechanism 37 grips the bearing housing 3 by gripping and fixing the gripping head 4. The gripping mechanism 37 includes a gripping seat 38, a gripping clamp 40, and a clamp control assembly.

[0041] The gripping seat 38 is welded and fixed to the bottom surface of the mounting plate 35, and a T-shaped slide rail 39 is fixedly connected to the bottom surface of the gripping seat 38. A pair of gripping blocks 40 are slidably arranged on the T-shaped slide rail 39. The gripping blocks 40 are slidably arranged on the T-shaped slide rail 39 through a T-shaped groove 41 that slides with the T-shaped slide rail 39. A central screw hole 42 is provided on the side wall of the gripping block 40 along the length direction of the gripping seat 38.

[0042] The clamping block control assembly is used to drive the gripping blocks 40 to move closer to each other to grip and fix them. The clamping block control assembly includes a bearing seat 43, a double-ended screw 44, and a working motor 45.

[0043] In this embodiment, there are two bearing seats 43. The bearing seats 43 are screwed to the bottom surface of the gripping seat 38, and the two bearing seats 43 are respectively set at both ends of the T-shaped slide rail 39.

[0044] The double-ended screw 44 is rotatably mounted on two bearing seats 43. The double-ended screw 44 is a screw with two threads. The two threads of the double-ended screw 44 are respectively threaded to the gripping block 40 through the central screw hole 42. Since the gripping block 40 is slidably mounted on the T-shaped slide rail 39 through the T-shaped slide groove 41 that slides with the T-shaped slide rail 39, the rotation of the double-ended screw 44 will drive the two gripping blocks 40 to move closer or further apart.

[0045] The double-ended screw 44 passes through the bearing housing 43 and is connected to the output shaft of the working motor 45. The working motor 45 is screwed to the bottom surface of the gripping seat 38. The working motor 45 is used to drive the double-ended screw 44 to rotate forward or in reverse.

[0046] After the bearing housing 3 is loaded with tapered roller bearings, it is transported to the loading position by the loading conveyor 46. The box grabbing device places the bearing housing 3 loaded with cleaned tapered roller bearings onto the unloading conveyor 47, and the unloading conveyor 47 sends the bearing housing 3 loaded with cleaned tapered roller bearings to the next process.

[0047] When this tapered roller bearing cleaning machine is in operation:

[0048] S1: The feeding conveyor 46 transports the bearing housing 3 containing tapered roller bearings to the feeding position;

[0049] S2: Cylinder 34 drives vertical slide 31 to move downward until the top of gripper head 4 is between two gripping blocks 40. Working motor 45 drives double-headed screw 44 to rotate. The rotation of double-headed screw 44 will drive the two gripping blocks 40 to move closer to each other and clamp and fix gripper head 4. Then cylinder 34 drives vertical slide 31 to move upward.

[0050] S3: The flat drive motor 19 drives the driven bevel gear 24 to rotate through the main bevel gear 20. Then the output gear 25, which is coaxially connected to the driven bevel gear 24 through the flat shaft 23, rotates accordingly. Since the output gear 25 meshes with the rack and pinion track 15, the smooth seat 17, which is slidably set on the worktable 10, drives the bearing housing 3 loaded with tapered roller bearings to move above the cleaning chamber 2 of the ultrasonic cleaner 1.

[0051] S4: Cylinder 34 drives vertical slide 31 to move downward, which will drive bearing box 3 to move downward and put it into the cleaning chamber 2 of ultrasonic cleaner 1.

[0052] This tapered roller bearing cleaning machine can automatically clean tapered roller bearings, which helps reduce the labor intensity of workers and improve processing efficiency.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
