Description

Technical Field

[0001] This application relates to the technical field of bearing production equipment, and in particular to a cleaning device for the inner and outer rings of bearings. Background Art

[0002] During the bearing production process, it is necessary to first assemble the various components of the bearing to form semi-finished products, and then clean the semi-finished products to reduce the impact of impurities on the bearing performance. After the semi-finished products are cleaned, they can be called finished products.

[0003] Currently, when cleaning the assembled semi-finished products, an ultrasonic shaking cleaning machine is usually used. The working principle of the ultrasonic shaking cleaning machine is to place multiple semi-finished products in a container and drive the container to move in and out of the cleaning pool filled with cleaning liquid in a shaking manner, so that the multiple semi-finished products in the container can fully contact the cleaning liquid. At the same time, the ultrasonic shaking cleaning machine will generate ultrasonic waves in the cleaning pool to help clean the semi-finished products in the cleaning pool.

[0004] The ultrasonic shaking cleaning machine can clean a large number of semi-finished products at the same time, with high cleaning efficiency and good cleaning effect. However, during the use of the ultrasonic shaking cleaning machine, the multiple semi-finished products placed in the container are prone to bumping against each other during the shaking movement of the container, resulting in wear or damage to the bearing surface of the semi-finished products, thereby reducing the quality of the bearing products obtained after cleaning, and even possibly scrapping the bearing products obtained after cleaning. Moreover, after the bearings are cleaned on the ultrasonic shaking cleaning machine, the process of discharging the bearings is relatively messy, and it is necessary for the staff to take out multiple bearings and arrange them regularly to facilitate the subsequent delivery of the cleaned bearings to the next device for inspection of the cleaning effect. Summary of the Invention

[0005] This application provides a cleaning device for the inner and outer rings of bearings, which can reduce the probability of the bearings being damaged during cleaning while maintaining high cleaning efficiency and good cleaning effect, improve the quality of the bearings after cleaning, and the cleaned bearings can be arranged regularly, facilitating the transportation by the staff.

[0006] This application provides a cleaning device for the inner and outer rings of bearings, adopting the following technical solutions:

[0007] A cleaning device for the inner and outer rings of bearings includes a transportation mechanism, a plurality of cleaning mechanisms, a plurality of air-drying mechanisms, and a plurality of loading units. The plurality of cleaning mechanisms and the plurality of air-drying mechanisms are arranged along the transportation direction;

[0008] The transport mechanism includes two transport tracks and a first drive assembly. Both of the transport tracks pass through a number of the cleaning mechanisms and a number of the air-drying mechanisms along the transport direction. The load-carrying unit can pass between the two transport tracks, and the first drive assembly drives the load-carrying unit to move along the transport direction.

[0009] The load-carrying unit includes a frame body and a plurality of support rods. The support rods are detachably connected to the frame body and are located in the internal space of the frame body. The cross-sectional dimension of the support rod is smaller than the dimension of the inner ring of the bearing.

[0010] By adopting the above technical solution, the first drive assembly drives a plurality of load-carrying units to sequentially pass through a number of cleaning mechanisms and a number of air-drying mechanisms along the transport direction. And a plurality of bearings can be sleeved on each support rod of the load-carrying unit, so that the cleaning equipment can not only clean the inner and outer rings of a relatively large number of bearings simultaneously, maintaining a high cleaning efficiency, but also the bearings can be cleaned first and then air-dried, maintaining a good cleaning effect. And the bearings complete the cleaning process in a state of being sleeved on the support rods all the time, which can not only reduce the damage caused by mutual collision of the bearings during the cleaning process and improve the quality of the final bearing products, but also the cleaned bearings are neatly arranged on the support rods, which is convenient for the staff to transport the cleaned bearings to the next equipment to inspect the cleaning effect.

[0011] Optionally, a number of protruding portions are provided on the circumferential surface of the support rod. The number of the protruding portions are equally spaced along the length direction of the support rod. The bearing is sleeved on the support rod and is located between adjacent protruding portions.

[0012] By adopting the above technical solution, when a plurality of bearings are sleeved on the support rod, the bearings are stuck between adjacent two protruding portions under the action of gravity, which can keep the plurality of bearings on the same support rod at a distance from each other during the cleaning process and reduce the probability of cleaning dead angles on the surfaces of the inner and outer rings of the bearings caused by the bearings being in close contact. And when the staff sleeves the bearings on the support rod, the number of the protruding portions can be used as a reference, which is convenient for the staff to sleeve a plurality of bearings on the support rod one by one.

[0013] Optionally, the protruding portion has two guiding surfaces and a protecting surface. The two guiding surfaces are respectively located at both ends of the protruding portion along the length direction of the support rod. The protecting surface is located between the two guiding surfaces, and the surface of the protecting surface is smooth. The cross-sectional dimension of the guiding surface at one end close to the protecting surface is larger than the cross-sectional dimension of the guiding surface at the other end far from the protecting surface.

[0014] By adopting the above technical solution, when the bearing is placed on the carrier unit in the form of being sleeved on the support rod, errors in the bearing sleeve process or the carrier unit during transportation may cause the bearing to fail to be located between two adjacent protrusions; when one side of the bearing abuts against a guide surface, the guide surface will guide the bearing to be displaced during the transportation of the carrier unit until it is located between two adjacent protrusions; when the inner ring of the bearing abuts against the protective surface, since the protective surface is smooth, the bearing can be displaced during the transportation of the carrier unit until one side of the bearing abuts against a guide surface, thereby improving the position stability of the bearing on the carrier unit, reducing the friction between the protective surface and the inner ring of the bearing, and further reducing the probability of damage to the inner and outer ring surfaces of the bearing during the cleaning process.

[0015] Optionally, the loading unit further includes a paddle, which is located in the internal space of the frame and is slidably connected to the frame, and the sliding direction of the paddle is parallel to the length direction of the support rod; the paddle is located on one side of the support rod, and a plurality of clearance grooves are provided on the paddle, and the plurality of clearance grooves correspond one-to-one to the plurality of support rods; when the bearing is located between adjacent protrusions, the outer ring surface of the bearing is aligned and flush with the groove wall of the clearance groove along the length direction of the support rod.

[0016] By adopting the above technical solution, after multiple bearings are respectively mounted on multiple support rods and multiple support rods are connected to the frame, the control paddle slides through one side of the multiple bearings. The paddle can smoothly pass through one side of the bearing located between adjacent protrusions, and can also move the bearing whose single side is against a guide surface and the bearing whose inner ring is against a protective surface to move between the corresponding two adjacent protrusions, thereby making it convenient for staff to arrange the placement positions of multiple bearings on the loading unit.

[0017] Optionally, when the bearing is located between adjacent protrusions, two sides of the inner ring of the bearing respectively abut against the guide surfaces of two adjacent protrusions;

[0018] The plurality of support rods are rotatably connected to the frame, and the rotation axis of the support rod is parallel to the length direction of the support rod; the loading unit further comprises a transmission gear and a linkage assembly, the transmission gear drives one of the support rods to rotate, the linkage assembly drives the plurality of support rods to rotate in the same direction and synchronously, and the rotation of the support rod drives the inner ring of the bearing to rotate relative to the outer ring;

[0019] A rack is arranged on the transport track, and when the object-carrying unit is located between two transport tracks, the rack is meshed with the transmission gear.

[0020] By adopting the above technical solution, when the bearing is stable at the position between two adjacent convex parts, a distance is always maintained between the inner ring of the bearing and the support rod, so that the inner ring of the bearing can be comprehensively cleaned during the cleaning process, reducing the probability of cleaning dead corners on the surface of the inner ring of the bearing caused by the direct contact between the inner ring of the bearing and the support rod, thereby improving the cleaning effect of the bearing after cleaning; during the process of the loading unit moving and transporting along the transport track under the action of the first driving component, the rack and the transmission gear cooperate to drive multiple support rods to rotate synchronously. While the support rods are rotating, the inner ring of the bearing on the support rods will rotate relative to the outer ring, thereby reducing the cleaning dead corners of the outer ring of the bearing during the cleaning process and further improving the cleaning effect of the bearing placed on the loading unit for cleaning.

[0021] Optionally, both ends of the convex part extend around the surface of the support rod and are connected end to end to form a ring, and the plane where the ring formed by the convex part is located is inclined relative to the length direction of the support rod.

[0022] By adopting the above technical solution, the convex part being a ring structure can enable the bearing located between two adjacent convex parts to remain between the two adjacent convex parts during the rotation of the support rod, improving the position stability of the bearing on the support rod; moreover, the ring structure of the convex part is inclined. When the support rod rotates, the bearing located between two adjacent convex parts will move back and forth slightly along the length direction of the support rod, thereby being able to expand the range and probability of the bearing being cleaned during the transportation and movement on the loading unit, and further improving the cleaning effect of the bearing.

[0023] Optionally, it further includes a housing. The interior of the housing has several first installation spaces for installing the cleaning mechanism and several second installation spaces for installing the air drying mechanism. The transport track penetrates the housing and passes through several of the first installation spaces and several of the second installation spaces;

[0024] The cleaning mechanism includes an ultrasonic cleaning device and a spray cleaning device, and the ultrasonic cleaning device and the spray cleaning device are sequentially arranged in the first installation space along the transport direction.

[0025] By adopting the above technical solution, after multiple bearings are placed on the loading unit, the loading unit moves along the transport track under the action of the first driving component. After the loading unit enters the first installation space, the bearings are first ultrasonically cleaned and then spray cleaned. During the ultrasonic cleaning process, the bearings will be immersed in the cleaning oil and cleaned by ultrasonic waves. During the spray cleaning process, the bearings will be sprayed with the cleaning oil. Multiple different cleaning methods can enhance the cleaning effect of the cleaning mechanism on the bearings, thereby improving the cleaning effect of the bearings.

[0026] Optionally, the cleaning mechanism further includes two partition plates, both of which are vertically arranged in the first installation space and are parallel to each other. The two partition plates divide the first installation space into a liquid collection space, an ultrasonic space, and a spraying space in sequence along the transportation direction; through holes for the transportation track to pass through are formed on the partition plates, and the liquid collection space communicates with the ultrasonic space and the ultrasonic space communicates with the spraying space through the through holes;

[0027] The cleaning mechanism further includes a plurality of flow-stop blocks, which are arranged on the partition plates and located in the through holes, and the flow-stop blocks seal the gap between the transportation track and the partition plates.

[0028] By adopting the above technical solution, the partition plates separate the ultrasonic space from the spraying space, which can reduce the probability of mutual influence between the ultrasonic cleaning device and the spraying cleaning device; when the cleaning oil in the ultrasonic space overflows, the cleaning oil will flow into the liquid collection space and the spraying space through the through holes. At the same time, the flow-stop blocks can effectively prevent the cleaning oil from flowing out of the gap between the transportation track and the partition plates, thereby reducing the probability of cleaning oil overflow, keeping a certain amount of cleaning oil in the ultrasonic space, and further enabling the ultrasonic cleaning device to maintain a high cleaning effect on the bearings.

[0029] Optionally, the cleaning mechanism further includes a number of reflux devices, which are respectively arranged in the liquid collection space and the spraying space. A reflux port is further formed on the partition plate below the through hole, and the reflux device controls the opening and closing of the reflux port.

[0030] By adopting the above technical solution, after the cleaning oil overflows from the ultrasonic space into the liquid collection space and the spraying space, the reflux device can drive the overflowing cleaning oil to flow back into the ultrasonic space through the reflux port, thereby improving the utilization rate of the cleaning oil and reducing the waste of cleaning oil during the use of the cleaning equipment.

[0031] Optionally, the air-drying mechanism includes a cold air device and a hot air device, which are sequentially arranged in the second installation space along the transportation direction.

[0032] By adopting the above technical solution, after the load-carrying unit with a plurality of bearings moves into the second installation space along the transportation track, the cold air device first blows off the cleaning oil, dust and other impurities remaining on the surface of the bearings, and then the hot air device dries the surface of the bearings, thereby further improving the quality of the finally cleaned bearings.

[0033] In summary, the present application includes at least one of the following beneficial effects:

[0034] 1. While maintaining a high cleaning efficiency and a good cleaning effect, it can reduce the probability of the bearing being damaged during the cleaning process, improve the quality of the bearing after cleaning; and the bearings after cleaning can be arranged regularly, facilitating the transportation by the staff;

[0035] 2. It can reduce the cleaning dead corners existing in the cleaning process of the bearing and improve the cleaning effect of the bearing;

[0036] 3. It can enable the bearing to move regularly and reciprocally while being cleaned, increasing the range and probability of the bearing being cleaned, further reducing the cleaning dead corners, and thus further improving the cleaning effect of the bearing. Description of the Drawings

[0045] The following Figures 1-7 further describes the present application in detail.

[0046] Referring to Figure 1 and Figure 2 The embodiment of the present application discloses a cleaning device for the inner and outer rings of a bearing 9, including a transportation mechanism 1, a cleaning mechanism 2, an air drying mechanism 3, a housing 4, and a plurality of carrying units 5. After a plurality of bearings 9 are placed on the carrying units 5, the transportation mechanism 1 drives the plurality of carrying units 5 to sequentially pass through the cleaning mechanism 2 and the air drying mechanism 3. The cleaning mechanism 2 cleans the bearing 9 with a cleaning oil dedicated to bearing 9 cleaning. The air drying mechanism 3 removes the residual cleaning oil and dust and other impurities on the surface of the cleaned bearing 9, and then sends the cleaned bearing 9 to the next device for inspection of the cleaning effect.

[0047] Preferably, the housing 4 is integrally in a cuboid structure. A plurality of first installation spaces 41 for installing the cleaning mechanism 2 and a plurality of second installation spaces 42 for installing the air drying mechanism 3 are opened inside the housing 4. Preferably, the shapes of the first installation space 41 and the second installation space 42 are both cuboids. Preferably, two cleaning mechanisms 2 and one air drying mechanism 3 are installed inside the housing 4. The two cleaning mechanisms 2 and one air drying mechanism 3 are sequentially distributed along the length direction of the housing 4 inside the housing 4, that is, the two first installation spaces 41 and one second installation space 42 are sequentially distributed along the length direction of the housing 4 inside the housing 4.

[0048] At the top of the housing 4, corresponding to two first installation spaces 41 and a second installation space 42, there are three movable cover plates 43 respectively. Preferably, the cover plates 43 are movably connected in a rotational manner. After the cover plates 43 are closed, the corresponding first installation space 41 or second installation space 42 is covered and sealed.

[0049] Referring to Figure 2 , in one embodiment, the cleaning mechanism 2 includes two partition plates 21. Both of the two partition plates 21 are fixedly installed in the first installation space 41, and the bottom of the partition plate 21 abuts against the bottom wall of the first installation space 41. The two partition plates 21 are parallel to each other, and the plane where the partition plates 21 are located is perpendicular to the length direction of the housing 4. The two partition plates 21 divide the first installation space 41 into a liquid collection space 411, an ultrasonic space 412, and a spraying space 413. The liquid collection space 411, the ultrasonic space 412, and the spraying space 413 are sequentially distributed along the length direction of the housing 4 towards the position close to the second installation space 42.

[0050] At a position near the top of the partition plate 21, there is a relief opening 211 penetrating in a direction perpendicular to the plane where the partition plate 21 is located for the carrying unit 5 to pass through. Preferably, the carrying unit 5 is transported and moved inside the housing 4 in a direction parallel to the length direction of the housing 4. The liquid collection space 411 and the ultrasonic space 412 are communicated through the relief opening 211, and the ultrasonic space 412 and the spraying space 413 are also communicated through the relief opening 211.

[0051] The cleaning mechanism 2 further includes an ultrasonic cleaning device 22 and a spraying cleaning device 23.

When the carrying unit 5 is transported and moved through the first installation space 41, the carrying unit 5 will pass above the ultrasonic cleaning device 22 and below the spraying cleaning device 23. Preferably, the ultrasonic cleaning device 22 is an ultrasonic emitter and preferably emits ultrasonic waves vertically upward. Preferably, there is a certain amount of cleaning oil maintained in the ultrasonic space 412, and the liquid level of the cleaning oil is higher than the bottom wall of the relief opening 211. After the carrying unit 5 enters the ultrasonic space 412, a plurality of bearings 9 placed on the carrying unit 5 can be completely immersed in the cleaning oil. Preferably, the spraying cleaning device 23 is a plurality of spraying pipe fittings capable of spraying cleaning oil vertically downward. The spraying pipe fittings are externally connected to a cleaning oil source, and the oil liquid sprayed by the spraying cleaning device 23 forms a cleaning oil circulation with the cleaning oil source after falling to the bottom of the spraying space 413. Since the ultrasonic emitter, the spraying pipe fittings, and the cleaning oil circulation are all common prior arts in the field, they will not be elaborated here.

[0052] When the cleaning device is in use, the oil in the ultrasonic space 412 will overflow from the two relief openings 211 into the liquid collection space 411 and the spraying space 413 respectively, so as to keep a certain amount of oil in the ultrasonic space 412. In one embodiment, the cleaning mechanism 2 further includes two reflux devices 24, and the bottom of the partition 21 is also penetrated with a reflux port 212.

Preferably, the reflux device 24 is an oil pump, and the reflux device 24 can drive the cleaning oil in the liquid collection space 411 and the spraying space 413 to flow back into the ultrasonic space 412 through the reflux port 212 according to the amount of cleaning oil in the ultrasonic space 412. Since the functions of the oil pump and the reflux device 24 are common prior arts, they will not be elaborated here.

[0053] The cleaning mechanism 2 further includes a plurality of flow-stop blocks 25. Correspondingly, preferably, there are eight flow-stop blocks 25 in total. Two flow-stop blocks 25 are fixedly installed at the openings at both ends of the first installation space 41 for the loading unit 5 to enter and exit, and at the positions of the relief openings 211 on the two partitions 21. The flow-stop blocks 25 are used to reduce the overflow of cleaning oil, and the loading unit 5 will pass between the two flow-stop blocks 25 during the transportation and movement. Preferably, the cross-section of the flow-stop block 25 is concave-shaped, and two flow-stop blocks 25 form a group. The openings of the concave-shaped structures of the same group of flow-stop blocks 25 face each other, and preferably, the flow-stop block 25 is made of rubber material.

[0054] In one embodiment, the air-drying mechanism 3 includes a cold air device 31 and a hot air device 32, and both the cold air device 31 and the hot air device 32 are fixedly installed in the second installation space 42. Both the cold air device 31 and the hot air device 32 are located at the top of the second installation space 42. The cold air device 31 is located at one end of the second installation space 42 close to the first installation space 41, and the hot air device 32 is located at the end of the second installation space 42 far from the first installation space 41. When the loading unit 5 passes through the second installation space 42, the loading unit 5 will pass under the cold air device 31 and the hot air device 32 in sequence. Preferably, both the cold air device 31 and the hot air device 32 are blowers. Among them, the cold air device 31 can blow out normal-temperature air downward, and the hot air device 32 can blow out heated air downward. The cold air device 31 is used to blow off the cleaning oil and dust and other impurities remaining on the inner and outer ring surfaces of the bearing 9 after cleaning, and the hot air device 32 is used to dry the inner and outer ring surfaces of the bearing 9. Since the blower is a common prior art, it will not be elaborated here.

[0055] Back to Figure 1 and Figure 2, in one embodiment, the transport mechanism 1 includes two transport tracks 11 and a first drive assembly 12. The transport tracks 11 pass through the housing 4 in a direction parallel to the length direction of the housing 4. Preferably, the cross-section of the transport tracks 11 is concave-shaped. The openings of the concave-shaped structures of the two transport tracks 11 face each other, and one end of the transport track 11 facing away from the opening of its own concave-shaped structure is fixedly connected to the flow-stop block 25. A plurality of flow-stop blocks 25 respectively seal the gaps between the transport track 11 and the housing 4 and between the transport track 11 and the partition 21. The space between the two transport tracks 11 is for the transport and movement of the load-carrying unit 5. During the transport and movement of the load-carrying unit 5, both sides thereof are respectively in contact with and against the two transport tracks 11.

[0056] The first drive assembly 12 is located on one side of the housing 4 in the length direction, and the first drive assembly 12 is located on the side where the feeding end of the housing 4 is located. The first drive assembly 12 drives a plurality of load-carrying units 5 to sequentially move along the transport track 11. Preferably, the first drive assembly 12 includes a cylinder and a push plate. The cylinder drives the push plate to reciprocate in a direction parallel to the length direction of the housing 4. When the cylinder drives the push plate to move away from the housing 4 to the extreme position, a space adapted to the load-carrying unit 5 is formed between the push plate and the transport track 11; when the cylinder drives the push plate to move towards the housing 4 to the extreme position, the push plate can push the load-carrying unit 5 to move into the space between the two transport tracks 11. Since the driving form of the combination of the cylinder and the push plate is a common prior art, it will not be elaborated here.

[0057] Refer to Figure 1 , in one embodiment, the cleaning device further includes a feeding mechanism 6 and a discharging mechanism 7. The feeding mechanism 6 is located on the side of the housing 4 close to the feeding end, and the discharging mechanism 7 is located on the side of the housing 4 close to the discharging end. Preferably, both the feeding mechanism 6 and the discharging mechanism 7 are belt conveyor structures with guide rails. Since the above structures are common prior arts, they will not be elaborated here.

[0058] Preferably, the feeding direction of the feeding mechanism 6 is perpendicular to the transporting direction of the transporting mechanism 1, and after the carrying unit 5 is transported and moved on the feeding mechanism 6, it will be sent to the space between the first driving assembly 12 and the transporting track 11. In an embodiment, preferably, a limiting member 101 and a sensing member 102 are further installed at one end of the feeding mechanism 6 close to the housing 4. When the feeding mechanism 6 transports the carrying unit 5 to the space between the first driving assembly 12 and the transporting track 11, the carrying unit 5 will abut against the limiting member 101, and the limiting member 101 restricts the feeding mechanism 6 from continuing to drive the carrying unit 5 to move along the feeding direction; the sensing member 102 is fixedly installed on the limiting member 101, and the sensing member 102 is signal-connected to the cylinder of the first driving assembly 12. When there is a carrying unit 5 abutting against the limiting member 101, the sensing member 102 can sense the carrying unit 5 and transmit a signal to the cylinder of the first driving assembly 12. After receiving the signal, the cylinder will drive the push plate to move towards the housing 4 to the extreme position; normally, the cylinder of the first driving assembly 12 will drive the push plate to move away from the housing 4 to the extreme position and remain there, that is, the first driving assembly 12 is controlled by the sensing member 102. Preferably, the sensing member 102 is an infrared sensor. Since the infrared sensor is a common prior art, it will not be elaborated here.

[0059] Preferably, the discharging direction of the discharging mechanism 7 is also perpendicular to the transporting direction of the transporting mechanism 1, and the discharging direction of the discharging mechanism 7 is opposite to the feeding direction of the feeding mechanism 6. After the carrying unit 5 leaves the housing 4 along the transporting track 11, it will be sent to the discharging mechanism 7, and then the discharging mechanism 7 transports and moves the carrying unit 5.

[0060] In an embodiment, the cleaning device further includes a discharging platform 8. The discharging platform 8 is located on one side of the end of the discharging mechanism 7 far from the housing 4, and preferably, the discharging platform 8 is located between the feeding mechanism 6 and the discharging mechanism 7. Preferably, a second driving assembly 71, a limiting member 101 and a sensing member 102 are installed at the end of the discharging mechanism 7 far from the housing 4. The structure of the second driving assembly 71 is the same as that of the first driving assembly 12. The second driving assembly 71 drives the carrying unit 5 to move from the discharging mechanism 7 to the discharging platform 8, and the direction in which the second driving assembly 71 drives the carrying unit 5 to move is opposite to the direction in which the first driving assembly 12 drives the carrying unit 5 to move; the working principles of the limiting member 101 and the sensing member 102 are the same as those described above, so they will not be elaborated here.

[0061] Refer to Figure 3, in one embodiment, the loading unit 5 includes a frame body 51 and a plurality of support rods 52. The outer shape of the frame body 51 is in a cuboid structure, and the interior of the frame body 51 has a space for installing the plurality of support rods 52. The frame body 51 has two brackets 511 in its internal space. The length direction of the brackets 511 is parallel to the width direction of the frame body 51, and the two brackets 511 are respectively close to both ends of the frame body 51 in the length direction. A plurality of clamping grooves 5111 are equidistantly arranged along the length direction on the brackets 511, and the number of clamping grooves 5111 on each bracket 511 is equal to the number of support rods 52. The support rod 52 is in a cylindrical structure, and grooves 521 are opened at both ends of the circumferential side of the support rod 52 in the axial direction of itself. The support rod 52 is detachably connected to the frame body 51.

[0062] Preferably, the support rod 52 and the frame body 51 are detachably connected by a clamping method. After the two ends of the support rod 52 respectively enter from the openings of the two opposite clamping grooves 5111 on the two brackets 511, the two grooves 521 are respectively clamped and matched with the two opposite clamping grooves 5111 on the two brackets 511. At this time, the displacement of the support rod 52 in its own axial direction is limited.

[0063] The radial dimension of the support rod 52 is smaller than the radial dimension of the inner ring of the bearing 9. After a plurality of bearings 9 are sleeved on the support rod 52, the support rod 52 is then installed on the frame body 51, so that the plurality of bearings 9 can be placed on the loading unit 5 regularly. After a plurality of support rods 52 are sleeved with bearings 9 and a plurality of support rods 52 are all installed on the frame body 51, when the bearings 9 on the support rod 52 rotate around the sleeved support rod 52, they will always keep a distance from the bearings 9 on the adjacent support rods 52.

[0064] Referring to Figure 2 and Figure 3 , after the plurality of bearings 9 are placed on the loading unit 5, during the process of the loading unit 5 being transported and moved on the feeding mechanism 6, the axis of the support rod 52 is parallel to the feeding direction of the feeding mechanism 6. The position of the support rod 52 relative to the frame body 51 is closer to the feeding mechanism 6, and a distance is kept between the bearing 9 sleeved on the support rod 52 and the feeding mechanism 6; during the process of the loading unit 5 being transported and moved along the transport track 11, the axis of the support rod 52 is perpendicular to the transport direction of the transport mechanism 1, and at this time when the loading unit 5 enters the ultrasonic space 412, all the plurality of bearings 9 placed on the loading unit 5 can be immersed in the cleaning oil in the ultrasonic space 412.

[0065] Referring to Figure 4, In one embodiment, the circumferential side surface of the support rod 52 has a plurality of protrusions 522. The protrusions 522 are in a ring structure, and the axis of the protrusions 522 coincides with the axis of the support rod 52. The plurality of protrusions 522 are equally spaced along the axial direction of the support rod 52, and the plurality of protrusions 522 located at the same axial position on the support rod 52 are circumferentially arrayed with the axis of the support rod 52 as the axis.

[0066] Referring to Figure 5 and Figure 6 , the protrusion 522 includes two guiding surfaces 5221 and a protecting surface 5222. The two guiding surfaces 5221 are respectively located at both ends of the protrusion 522 along the axial direction of the support rod 52. The protecting surface 5222 is located between the two guiding surfaces 5221. The two ends of the guiding surface 5221 are respectively connected to the circumferential side surface of the support rod 52 and the protecting surface 5222. The guiding surface 5221 is an inclined surface and its surface is rough. When the axis of the support rod 52 is horizontal, the end of the guiding surface 5221 close to the protecting surface 5222 is the inclined upper end; the protecting surface 5222 is an arc surface and its surface is smooth. The protecting surface 5222 is symmetric about itself, and the two guiding surfaces 5221 on both sides of the protecting surface 5222 are symmetrically distributed with the symmetry plane of the protecting surface 5222 as the symmetry axis.

[0067] The minimum distance between two adjacent protecting surfaces 5222 on two adjacent protrusions 522 is less than the thickness of the bearing 9, and the maximum distance between two adjacent protecting surfaces 5222 on two adjacent protrusions 522 is greater than the thickness of the bearing 9. After the bearing 9 is sleeved on the support rod 52, with the bearing 9 located between two protrusions 522, and the two sides of the inner ring of the bearing 9 respectively abutting against the guiding surfaces 5221 of the two protrusions 522 and the axis of the bearing 9 being parallel to the axis of the support rod 52 as the standard. When one side of the inner ring of the bearing 9 abuts against a guiding surface 5221 after the bearing 9 is sleeved on the support rod 52, and the other side of the inner ring of the bearing 9 abuts against the circumferential side surface of the support rod 52, applying a little force to the bearing 9 in the direction parallel to the axis of the support rod 52 or the load-carrying unit 5 shakes during the transportation and movement process can cause the bearing 9 to displace, so that the two sides of the inner ring of the bearing 9 respectively abut against the guiding surfaces 5221 of the two protrusions 522 and the axis of the bearing 9 is parallel to the axis of the support rod 52; when the inner side surface of the inner ring of the bearing 9 abuts against the protecting surface 5222 after the bearing 9 is sleeved on the support rod 52, applying a little force to the bearing 9 in the direction parallel to the axis of the support rod 52 or the load-carrying unit 5 shakes during the transportation and movement process can cause the bearing 9 to displace, so that one side of the inner ring of the bearing 9 abuts against a guiding surface 5221 and the other side abuts against the circumferential side surface of the support rod.

[0068] Referring to Figure 4 and Figure 6The loading unit 5 further includes a paddle 55 for adjusting the position of the bearing 9 on the support rod 52. The paddle 55 is in the form of a long strip, and is located in the internal space of the frame 51 and on one side of the plurality of support rods 52. During the transportation of the loading unit 5, the paddle 55 is located above the support rod 52, and the length direction of the paddle 55 is perpendicular to the length direction of the support rod 52. Both ends of the paddle 55 in the length direction are slidably connected to the frame 51, and the sliding direction of the paddle 55 is parallel to the length direction of the support rod 52. A plurality of clearance grooves 551 are provided at one end of the paddle 55 close to the support rod 52, and the plurality of clearance grooves 551 are evenly spaced along the length direction of the paddle 55, and the plurality of clearance grooves 551 correspond to the plurality of support rods 52 one by one.

[0069] Preferably, the yield groove 551 is an arc-shaped groove. When the two sides of the inner ring of the bearing 9 are respectively abutted against the guide surfaces 5221 of the two adjacent protrusions 522 and the axis of the bearing 9 is parallel to the axis of the support rod 52, the paddle 55 can smoothly slide over the bearing 9; when the position of the bearing 9 on the support rod 52 is inaccurate, the sliding of the paddle 55 can push the bearing 9 to move until the position of the bearing 9 on the support rod 52 is accurate, that is, the paddle 55 can slide over the bearing 9.

[0070] Back to Figure 4 and Figure 5 A side frame of the frame 51 is detachably connected to other structures of the frame 51, and preferably the frame and other parts of the frame 51 are detachably connected by plugging. One end of each of the support rods 52 is rotatably connected to the frame, and the rotation axis of the support rod 52 coincides with its own axis.

[0071] The carrier unit 5 also includes a transmission gear 53 and a linkage assembly 54, which is fixedly installed inside the frame 51 and located on the other width side of the frame 51. Preferably, the linkage assembly 54 is a pulley transmission structure, which includes a plurality of rotating wheels and a synchronous belt, wherein the plurality of rotating wheels are rotatably connected to the frame 51, and the rotation axes of the plurality of rotating wheels are parallel to the length direction of the frame 51. The plurality of rotating wheels are evenly spaced along the width direction of the frame 51, and the synchronous belt is wound around the plurality of rotating wheels at the same time, so that the plurality of rotating wheels can rotate in the same direction and synchronously. Since the pulley transmission structure is a common prior art, it will not be described in detail here.

[0072] The number of the rotating wheels is equal to the number of the supporting rods 52 rotatably connected to the detachable frame. After the frame is plugged and connected to other parts of the frame body 51, the multiple supporting rods 52 correspond to the multiple rotating wheels one by one and are connected therebetween. Preferably, the end of the supporting rod 52 away from the detachable frame is also connected to the rotating wheel by plugging. After the supporting rod 52 is connected to the rotating wheel, the supporting rod 52 and the rotating wheel rotate synchronously.

[0073] On the linkage assembly 54, a gear is fixedly connected to one end of a rotating wheel away from the position where the support rod 52 is inserted and connected, and the rotating wheel rotates synchronously with the gear. The transmission gear 53 is rotatably connected to the frame 51. The rotation axis of the transmission gear 53 is parallel to the length direction of the frame 51. The transmission gear 53 is located on one side of the above-mentioned gear and meshes with the above-mentioned gear. Part of the transmission gear 53 is located inside the frame 51 and part is located outside the frame 51. Among the two transport tracks 11, a rack 111 adapted to the transmission gear 53 is fixedly installed along the length direction of one transport track 11. After the load unit 5 enters between the two transport tracks 11, the transmission gear 53 meshes with the rack 111. During the process of the load unit 5 being transported and moving along the transport track 11, the transmission gear 53 rotates under the action of the rack 111. The rotation of the transmission gear 53 drives the multiple rotating wheels on the linkage assembly 54 to rotate synchronously, thereby driving the multiple support rods 52 to rotate synchronously. At this time, if both sides of the multiple bearings 9 sleeved on the support rod 52 are in contact with the guide surface 5221, the rotation of the support rod 52 can drive the inner ring of the bearing 9 to rotate relative to the outer ring, reducing the cleaning dead angle.

[0074] Referring to Figure 7 , in one embodiment, the plane where the annular structure of the convex portion 522 is located is inclined with respect to the axis of the support rod 52, and the multiple convex portions 522 are parallel to each other. When the support rod 52 rotates, the bearings 9 sleeved on the support rod 52 will keep both sides in contact with the guide surface 5221, that is, the rotation of the support rod 52 can drive the inner ring of the bearing 9 to rotate relative to the outer ring. At the same time, the position of the bearing 9 on the support rod 52 along the axis direction of the support rod 52 will change at a certain frequency, so that the position of the bearing 9 relative to the support rod 52 can reciprocate along the axis direction of the support rod 52 with a certain amplitude. After the load unit 5 enters the first installation space 41, the displacement of the bearing 9 along the axis direction of the support rod 52 can promote the contact between itself and the cleaning oil, thereby further improving the cleaning effect of the bearing 9 by the cleaning oil.

[0075] Preferably, the inclination direction and inclination angle of the annular structure of the convex portion 522 on each support rod 52 are the same, and the position of the convex portion 522 on each support rod 52 relative to the support rod 52 where it is located is the same. In other embodiments, the inclination direction and inclination angle of the annular structure of the convex portion 522 on different support rods 52 can be different, and the position of the convex portion 522 on the support rod 52 relative to the support rod 52 where it is located can be staggered from the convex portion 522 on the adjacent support rod 52.

[0076] The implementation principle of an inner and outer ring cleaning device for a bearing 9 according to an embodiment of the present application is as follows:

[0077] After placing multiple bearings 9 on the load-carrying unit 5 in a sleeved manner on the support rod 52, control the loading of the load-carrying unit 5. After the load-carrying unit 5 is loaded to the designated position, the first driving assembly 12 drives the load-carrying unit 5 to move along the transport track 11, so that multiple load-carrying units 5 pass through the housing 4 in a state of being closely attached to each other in sequence; the load-carrying unit 5 first enters the first installation space 41, and the multiple bearings 9 placed on the load-carrying unit 5 are immersed in the cleaning oil in the ultrasonic space 412 and are ultrasonically cleaned by the ultrasonic cleaning device 22. Then, the multiple bearings 9 placed on the load-carrying unit 5 are sprayed and cleaned with cleaning oil by the spray cleaning device 23 in the spray space 413; after the load-carrying unit 5 passes through the cleaning of several cleaning mechanisms 2, it enters the second installation space 42. First, the cold air device 31 blows off the cleaning oil, dust and other impurities remaining on the inner and outer ring surfaces of the multiple bearings 9 placed on the load-carrying unit 5, and then the hot air device 32 dries the multiple bearings 9 placed on the load-carrying unit 5. After the load-carrying unit 5 is cleaned by several air-drying mechanisms 3, it is unloaded, and the bearings 9 are still arranged regularly after being removed from the load-carrying unit 5, which is convenient for sending them to the next device to inspect the cleaning effect of the bearings 9.

[0078] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape and principle of the present application should be covered within the protection scope of the present application.
