Description

Technical Field

[0001] The present application relates to the technical field of sliding bearings, and specifically to a tooling for cleaning the oil groove of a sliding bearing bushing. Background Art

[0002] The bushing, also known as the part of the sliding bearing in contact with the journal, plays a very important role in linking and supporting in the sliding bearing. It can ensure a stable connection between the shaft and the seat hole and support the rotation of the journal. When the bushing is working, a very thin oil film will be formed between it and the journal. This oil film can not only play a lubricating role, reduce friction and wear, but also take away the heat generated during the operation of the bushing, playing a role in cooling the bearing. And oil grooves are provided on the surface of the bushing to enable the lubricating oil to be evenly distributed on the surface of the bushing, avoiding excessive friction caused by insufficient lubricating oil. In this way, the service life of the bushing is extended, and the maintenance cost of the machine is also reduced, thereby improving production efficiency. After the oil groove is used for a period of time, its surface will become blocked by dirt. If not cleaned in time, it will cause difficulties in the flow of the lubricating oil and even affect the normal operation of the bearing.

[0003] Patent No. CN 117548392 A discloses a tooling for cleaning the oil groove of a sliding bearing bushing, including a limit piece, a cleaning plate, a cleaning cloth, a spoon head, etc. This invention combines the functions of removing and cleaning, and can solve the problems of inconvenient on-site cleaning of the oil groove, low cleaning efficiency and poor cleaning effect. The tooling of this design has a simple structure and is easy to use. During the use of the oil groove cleaner, under the action of two limit pieces, the cleaning plate can tilt up and down at a certain angle, which conforms to ergonomics, is more conducive to the operator to clean the waste residue in the oil groove of the bushing, is more labor-saving, and reduces the cleaning difficulty.

[0004] However, in use, it has the following defects:

[0005] Although the waste residue is pushed to the outer end of the oil groove by the tapered tooth groove and then cleaned out with a spoon head, during the cleaning process, since the waste residue is pushed too close to the edge of the outer side of the oil groove, the spoon head cannot fully contact the inner wall of the oil groove when scraping the waste residue, so that waste residue will remain in the dead corner of the oil groove edge line during scraping and is difficult to clean out. Utility Model Content

[0006] The purpose of the present application is to provide a tooling for cleaning the oil groove of a sliding bearing bushing, which solves the problem proposed in the background technology that although the waste residue is pushed to the outer end of the oil groove by the bevel gear groove and then cleaned out with a spoon head, during the cleaning process, since the waste residue is pushed too close to the edge of the outer side of the oil groove, the spoon head cannot fully contact the inner wall of the oil groove when scraping the waste residue, resulting in waste residue remaining in the dead corner of the oil groove edge line and being difficult to clean out.

[0007] To achieve the above object, the present application provides the following technical solution: A tooling for cleaning the oil groove of a sliding bearing bushing, including a bushing main body, an oil groove main body, a main frame, a sliding plate and a threaded rod. Side grooves are provided on the left and right inner side walls of the main frame, and both ends of the sliding plate are horizontally slidably connected inside the side grooves on both sides. A central groove is provided on the surface of the sliding plate, and a slider is horizontally slidably connected inside the central groove. The top surface of the slider is threadedly connected through the threaded rod, the top of the threaded rod is fixedly connected to the handle, the bottom of the threaded rod is fixedly connected to the center of the top of the bevel gear cylinder, and a sponge is fixedly connected to the bottom of the bevel gear cylinder.

[0008] In this technical solution, place the main frame on the surface of the bushing main body outside the oil groove main body and fit it. Then twist the extrusion bolt to drive the extrusion pad to move towards the bushing main body, and cooperate with the support block to squeeze the bushing main body tightly from both sides to maintain stability. Through the side groove, sliding plate, central groove, handle, bevel gear cylinder and sponge, the oil groove main body can be cleaned. Hold the handle by hand and drive the bevel gear cylinder below to slide along the edge line of the oil groove main body. During the movement of the bevel gear cylinder, the dirt and waste residue above the inner side wall of the oil groove main body will be scraped up, and the sponge below will scrape out the dirt and waste residue in the dead corner of the edge line. After walking around the edge line, these dirt and waste residue will be taken out, thereby improving the cleaning effect and the practicality of the device. After the cleaning is completed, loosen the extrusion bolt, move the main frame to another oil groove main body for continuous cleaning, and the cleaning brush can be removed to further brush and clean the inside of the previous oil groove main body. Since the cleaning brush is relatively fluffy, it can adapt to oil groove main bodies of various sizes during cleaning and can fit the inner wall of the oil groove main body. At the same time, through the threaded rod, handle and slider, it can adapt to the depths of different oil groove main bodies. When facing oil groove main bodies with different depths, only need to hold the handle and rotate the threaded rod to make the threaded rod lift and lower on the surface of the slider, driving the bevel gear cylinder below to move together, so that the sponge at the bottom of the bevel gear cylinder can contact the inner bottom of the oil groove main body in a compressed state, so that the sponge can be fully squeezed into the dead corner of the edge line for cleaning during the subsequent cleaning process, thus adapting to the cleaning requirements of oil grooves of various sizes and improving the adaptability and practicality of the device.

[0009] As an alternative embodiment of the technical solution of the present application, an extrusion bolt is threadedly connected through the center of one side surface of the main frame located outside the bearing shell body. One end of the extrusion bolt located inside the main frame is fixedly connected with an extrusion cushion block, and the orientation of the extrusion bolt is perpendicular to the sliding plate.

[0010] As an alternative embodiment of the technical solution of the present application, a clamping plate is movably clamped at the top end of the surface of the main frame on the opposite side of the extrusion bolt. The clamping plate is threadedly connected to the main frame through screws, and a cleaning brush is fixedly connected to one side of the clamping plate located outside the main frame.

[0011] As an alternative embodiment of the technical solution of the present application, support blocks are fixedly connected to the lower left and right sides of the inner wall of the main frame on one side of the clamping plate.

[0012] As an alternative embodiment of the technical solution of the present application, the diameter of the bevel gear cylinder is the same as the diameter of the lower sponge.

[0013] As an alternative embodiment of the technical solution of the present application, an anti-slip pad is fixedly connected to the surface of the side of the extrusion cushion block facing the bearing shell body.

[0014] Compared with the prior art, the beneficial effects of the present application are as follows:

[0015] 1. Through the side groove, sliding plate, central groove, handle, bevel gear cylinder and sponge, the present application can clean the oil groove body. Hold the handle by hand to drive the lower bevel gear cylinder to slide along the edge line of the oil groove body. During the movement of the bevel gear cylinder, the dirt and waste on the upper inner wall of the oil groove body will be scraped up, and the lower sponge will scrape out the dirt and waste in the dead corner of the edge line. After walking around the edge line, these dirt and waste will be taken out, thus improving the cleaning effect and the practicability of the device.

[0016] 2. Through the threaded rod, handle and slider, the present application can adapt to the depths of different oil groove bodies. When facing oil groove bodies with different depths, only need to hold the handle and rotate the threaded rod to make the threaded rod lift on the surface of the slider, drive the lower bevel gear cylinder to move together, so that the sponge at the bottom of the bevel gear cylinder can contact the inner bottom of the oil groove body in a compressed state. In this way, in the subsequent cleaning process, the sponge can be fully squeezed into the dead corner of the edge line for cleaning, thus adapting to the cleaning requirements of oil grooves of various sizes and improving the adaptability and practicability of the device.

[0021] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the following will be further elaborated in combination with specific implementation manners.

[0022] As Figure 1 shown, a tooling for cleaning the oil groove of a sliding bearing bushing includes a bushing body 1, an oil groove body 2, a main frame 3, a sliding plate 8 and a threaded rod 11. The surface of the bushing body 1 is equidistantly provided with oil groove bodies 2 in a circumferential array, and the main frame 3 is located on the surface of the bushing body 1 outside the oil groove body 2.

[0023] As Figure 1 shown, a clamping plate 14 is movably clamped at the top end of the surface of the main frame 3 on the opposite sides of the extrusion bolt 4. The clamping plate 14 is threadedly connected to the main frame 3 through a screw, and a cleaning brush 15 is fixedly connected to one side of the clamping plate 14 located outside the main frame 3. The cleaning brush 15 can be removed to brush the oil groove body 2. Since the cleaning brush 15 is relatively fluffy, it can adapt to the cleaning of oil groove bodies 2 of various sizes.

[0024] As Figure 2 shown, side grooves 7 are opened on the left and right inner side walls of the main frame 3, and both ends of the sliding plate 8 are horizontally slidably connected inside the side grooves 7 on both sides respectively. A central groove 9 is opened on the surface of the sliding plate 8, and a slide block 10 is horizontally slidably connected inside the central groove 9. The settings of the side grooves 7 and the central groove 9 enable the slide block 10 to move freely inside the main frame 3. The top surface of the slide block 10 is threadedly connected through the threaded rod 11. The top end of the threaded rod 11 is fixedly connected to the handle 111, and the bottom of the threaded rod 11 is fixedly connected to the center of the top end of the bevel gear cylinder 12. The bottom of the bevel gear cylinder 12 is fixedly connected to a sponge 13. The diameter of the bevel gear cylinder 12 is the same as the diameter of the sponge 13 below, so that when the inner wall of the bevel gear cylinder 12 is cleaned, the sponge 13 below can simultaneously clean the dead corners of the edge line.

[0025] As Figure 1 and Figure 2As shown in the figure, a pressing bolt 4 is threadedly connected through the center of one side surface of the main frame 3 located outside the bearing shell body 1. One end of the pressing bolt 4 located inside the main frame 3 is fixedly connected with a pressing cushion block 5. A non-slip pad 501 is fixedly connected to one side surface of the pressing cushion block 5 facing the bearing shell body 1. And the orientation of the pressing bolt 4 is perpendicular to the sliding plate 8. The non-slip pad 501 can ensure that the main frame 3 will not sway randomly and cause deviation during the cleaning process.

[0026] As Figure 2 As shown in the figure, support blocks 6 are fixedly connected to the lower parts of the left and right sides of the inner wall of the main frame 3 on one side of the clamping plate 14. The support blocks 6 are made of rubber and are relatively soft, which can provide protection for the surface of the bearing shell body 1 during the extrusion and fixation process.

[0027] During actual use, place the main frame 3 on the surface of the bearing shell body 1 outside the oil tank body 2 to fit. Then twist the pressing bolt 4 to drive the pressing cushion block 5 to move towards the bearing shell body 1, and cooperate with the support blocks 6 to squeeze the bearing shell body 1 tightly from both sides, so as to maintain stability. Through the side groove 7, the sliding plate 8, the central groove 9, the handle 111, the bevel gear cylinder 12 and the sponge 13, the oil tank body 2 can be cleaned. Hold the handle 111 by hand and drive the lower bevel gear cylinder 12 to slide along the edge line of the oil tank body 2. The bevel gear cylinder 12 will scrape up the dirt and waste residues on the upper inner wall of the oil tank body 2 during the movement, and the lower sponge 13 will scrape out the dirt and waste residues in the dead corners of the edge line. After walking around the edge line, these dirt and waste residues will be taken out, thus improving the cleaning effect and the practicability of the device. After the cleaning is completed, loosen the pressing bolt 4, move the main frame 3 to another oil tank body 2 for continuous cleaning, and the cleaning brush 15 can be taken down to further brush and clean the inner side of the previous oil tank body 2.
