Description

Technical Field

[0001] The present invention relates to the technical field of slewing bearings, and more specifically, it relates to an oiling device for the tooth grooves of a slewing bearing with a synchronous cleaning function. Background Art

[0002] A slewing bearing is a new type of mechanical component, also known as a turntable bearing, rotating bearing or slewing bearing. When in use, the repair and oiling of the slewing bearing are important steps to ensure its normal operation and extend its service life. During the repair process, the waste grease should be cleaned, and then oiling can be carried out.

[0003] After the slewing bearing is used, a large amount of waste grease and impurities will accumulate inside its tooth grooves. At this time, the slewing bearing needs to be repaired, otherwise it will cause wear of the slewing bearing. When cleaning the grease and oiling the slewing bearing, the staff holds a spatula and a cleaning cloth to scrape and wipe, or uses a manipulator to insert the spatula into the tooth grooves to scrape out the residual grease. At the same time, the tooth grooves after scraping the grease are wiped again with a cleaning cloth to avoid the situation of residual impurities inside.

[0004] However, in the existing cleaning method during the operation process, grease is likely to accumulate on the spatula, covering the entire surface of the spatula, and the spatula is largely contaminated. If in order to avoid grease residue when the spatula cleans the next tooth groove, the spatula needs to be cleaned repeatedly. If not cleaned in time, the tooth grooves will be secondarily contaminated due to the grease accumulated on the spatula, leaving grease and impurities inside the tooth grooves. And during the cleaning process, the spatula will also have the situation of incomplete cleaning due to the contamination of the cleaning cloth or too much grease accumulated on the spatula. These residues will affect the entire cleaning process and the cleaning effect. Summary of the Invention

[0005] Aiming at the deficiencies existing in the prior art, the purpose of the present invention is to provide an oiling device for the tooth grooves of a slewing bearing with a synchronous cleaning function.

[0006] To achieve the above purpose, the present invention provides the following technical solution: An oiling device for the tooth grooves of a slewing bearing with a synchronous cleaning function, including a base, an oiling component and a positioning component. The oiling component is installed on one side of the top of the base, and the oiling component is suitable for oiling the tooth grooves of the slewing bearing.

[0007] The positioning component is installed on the other side of the top of the base. The positioning component includes four groups of supports installed on the top of the base and a fixed disk arranged between the four groups of supports. An L-shaped plate for positioning the outer ring of the slewing bearing is arranged around and equidistantly on the top of the fixed disk, and the bottom of the L-shaped plate is clamped on the inner ring of the fixed disk.

[0008] A rotating assembly is installed on the top of the base and between the four groups of supports. The rotating assembly is connected to the inner ring of the slewing bearing tooth groove, and the rotating assembly is adapted to drive the rotation of the inner ring of the slewing bearing tooth groove.

[0009] An oil scraping assembly is installed on the top of the base and between two groups of supports. The oil scraping assembly is used to remove oil from the tooth grooves of the inner ring of the slewing bearing tooth groove.

[0010] The oil scraping assembly includes a fixed frame connected to the base, a connecting block and a fixing plate arranged on the side of the fixed frame close to the fixed disk. A second scraping mechanism is installed on the side wall of the fixing plate. The second scraping mechanism includes a scraper that displaces in the vertical direction. The second scraping mechanism is adapted to initially scrape oil inside the slewing bearing tooth groove. A first scraping mechanism is arranged on the side wall of the connecting block. The first scraping mechanism includes a U-shaped frame that is clamped with the slewing bearing tooth groove and is used for secondary oil scraping.

[0011] A cleaning assembly is installed on the top of the base and between the four supports. The cleaning assembly is located directly below the scraper.

[0012] The present invention is further configured as: the oiling assembly includes a support platform installed on one side of the top of the base and a first electric slide rail horizontally installed on the top of the support platform. A sliding table is slidably connected to the top of the first electric slide rail. One side of the sliding table extends to one end of the first electric slide rail and is installed with a second electric slide rail. The second electric slide rail is vertically installed. A driving motor and a transmission mechanism are slidably installed on the side of the second electric slide rail away from the sliding table. The output end of the driving motor is connected to the input end of the transmission mechanism. The output end of the transmission mechanism is vertically installed with an oil injection box. An oiling head is installed through the bottom of the oil injection box.

[0013] By adopting the above technical solution, when the driving motor drives the driving wheel to rotate, the driving wheel applies the driving force to the synchronous belt, and the synchronous belt transmits the driving force to the driven wheel, causing the driven wheel, the oil injection box and the oiling head to rotate synchronously, so that the oiling head can rotate when oiling the inner ring tooth groove of the slewing bearing, thereby avoiding the situation of dryness or wear at the same position of the oiling head during oiling.

[0014] The present invention is further configured as: a positioning cylinder is horizontally installed on the side wall of each support. The positioning cylinder faces the fixed disk and is located above the fixed disk. The four positioning cylinders are arranged corresponding to the four L-shaped plates. The end of the piston rod of the positioning cylinder penetrates through the corresponding L-shaped plate and is connected with a bearing platform. The side wall and the inner bottom wall of the bearing platform are attached to the side wall and the outer bottom surface of the outer ring of the slewing bearing.

[0015] By adopting the above technical solution, when positioning the slewing bearing, the outer ring of the slewing bearing is placed on four bearing platforms, and then the bearing platforms are pushed by the positioning cylinder to move towards the slewing bearing, so as to horizontally position the slewing bearing, facilitating subsequent cleaning and oiling operations.

[0016] The present invention is further configured as: the rotating assembly includes a first ratchet wheel horizontally arranged below the fixed disk, four limiting frames are arranged equidistantly around the top of the first ratchet wheel, and a hook is connected between the top of the limiting frame and the bottom of the inner ring of the slewing bearing.

[0017] The present invention is further configured as: the rotating assembly further includes four racks installed equidistantly around the top of the base, a second ratchet wheel is rotatably connected to the side wall of each rack, the second ratchet wheel meshes with the bottom of the first ratchet wheel, a rotating motor is installed on the side wall of one of the racks, and the output end of the rotating motor is connected to a second ratchet wheel.

[0018] By adopting the above technical solution, when the rotating motor drives the corresponding second ratchet wheel to rotate, the second ratchet wheel drives the first ratchet wheel to rotate. Since the first ratchet wheel is meshed at multiple points by four second ratchet wheels, the first ratchet wheel rotates self-driven by the driving force, and the four second ratchet wheels assist in supporting the rotating first ratchet wheel. When the first ratchet wheel rotates, it drives the corresponding four limiting frames and hooks to displace synchronously, thereby pulling the inner ring of the slewing bearing to rotate. Since the tooth grooves of the slewing bearing are arranged at the inner ring position, the tooth grooves rotate and displace synchronously when the inner ring rotates. This movement state facilitates subsequent degreasing and oiling operations.

[0019] The present invention is further configured as: a driving cylinder is horizontally installed on one side of the fixed frame, the piston rod of the driving cylinder is connected to the side wall of the connecting block, and the driving cylinder is suitable for adjusting the distance between the first scraping mechanism and the second scraping mechanism and the tooth grooves of the slewing bearing.

[0020] The present invention is further configured as: a groove is formed in the side wall of the connecting block, a connecting rod is horizontally connected inside the groove, a spring is sleeved outside the connecting rod, one end of the spring is connected to the inner wall of the groove, a bearing block is slidably connected to the outer side wall of the connecting rod, one side of the bearing block is connected to one end of the spring, there are two groups of U-shaped frames, and both groups of U-shaped frames are installed on the side of the bearing block close to the connecting block. A gap is arranged between the two groups of U-shaped frames, and an inclined part is formed in the inner wall of the U-shaped frame.

[0021] The present invention is further configured as: the second scraping mechanism further includes a lifting cylinder vertically installed on the side wall of the fixed plate, the bottom of the piston rod of the lifting cylinder is connected to the scraper, and two scraping blocks are symmetrically installed on the side of the scraper close to the inner ring of the slewing bearing. The size of the scraping block is larger than the distance between adjacent tooth grooves of the slewing bearing.

[0022] The present invention is further configured such that: elastic scraping strips are connected to the bottoms of the two scraping blocks, and wedge-shaped protrusions are installed at the bottoms of the elastic scraping strips.

[0023] By adopting the above technical solution, when one of the tooth grooves of the slewing bearing moves to directly below the scraper, the lifting cylinder pushes the scraper downward, the scraper drives the two scraping blocks to move downward, the tooth groove of the slewing bearing adaptively squeezes the elastic scraping strip at the bottom of the scraping block, causing the elastic scraping strip to bend and fit against the side wall of the scraping block, and the wedge-shaped protrusion provided at the bottom of the elastic scraping strip moves to the position of the side wall of the scraping block through the bending of the elastic scraping strip. In this state, the wedge-shaped protrusion is in close contact with the side wall of the tooth groove of the slewing bearing. During the scraping process, the grease only exists below the wedge-shaped protrusion, and the scraper as a whole is not contaminated, greatly improving the functionality of the scraper. When the scraping block protrudes from below the tooth groove of the slewing bearing until the elastic scraping strip separates from the tooth groove of the slewing bearing, the elastic scraping strip returns to the horizontal state, that is, the grease is below the elastic scraping strip. In this state, it is convenient to use the cleaning assembly to clean the grease on the elastic scraping strip.

[0024] When the connecting block moves, the U-shaped frame moves synchronously, causing the U-shaped frame to perform secondary cleaning on the tooth groove after the initial grease cleaning and clean the top and bottom surfaces of the inner ring of the slewing bearing, that is, the U-shaped frame and the inclined portion cooperate to clean the grease on the inner ring tooth groove, top and bottom of the slewing bearing at the same time, avoiding the situation of grease residue.

[0025] The present invention is further configured such that: the cleaning assembly includes a cleaning frame installed on the top of the base, two winding rollers are installed on the top of the cleaning frame, and a cleaning cloth is drivingly connected between the two winding rollers. One of the winding rollers is used for unwinding the cleaning cloth, and the other winding roller is used for winding the cleaning cloth.

[0026] By adopting the above technical solution, when the scraping block moves to the position below the inner part of the tooth groove of the slewing bearing, the wedge-shaped protrusion is in contact with the top of the cleaning cloth. The side wall of the winding roller for winding is connected to an external drive. The external drive can be a servo motor, which is not specifically limited here. The external drive drives the winding roller to rotate, causing the cleaning cloth to be pulled out from the unwinding winding roller and wound by the winding roller for winding. The cleaning cloth wipes at the bottom of the scraping block, causing the grease on the elastic scraping strip and the wedge-shaped protrusion at the bottom of the scraping block to be taken away, thereby ensuring that the cleaning cloth is in a clean state when contacting the elastic scraping strip and the wedge-shaped protrusion, and avoiding secondary pollution.

[0027] In summary, the present application includes at least one of the following beneficial technical effects:

[0028] (1) By setting the second scraping mechanism, when one of the tooth grooves of the slewing bearing moves to directly below the scraper, the lifting cylinder pushes the scraper downward. The scraper drives the two scraping blocks downward, and the tooth groove of the slewing bearing adaptively squeezes the elastic scraping strip at the bottom of the scraping block, causing the elastic scraping strip to bend and fit against the side wall of the scraping block. The wedge-shaped protrusion provided at the bottom of the elastic scraping strip moves to the position of the side wall of the scraping block through the bending of the elastic scraping strip. In this state, the wedge-shaped protrusion is in close contact with the side wall of the tooth groove of the slewing bearing. During the scraping process, the grease only exists below the wedge-shaped protrusion, and the scraper as a whole is not contaminated, greatly improving the functionality of the scraper.

[0029] (2) When the scraping block protrudes from below the tooth groove of the slewing bearing until the elastic scraping strip separates from the tooth groove of the slewing bearing, the elastic scraping strip returns to the horizontal state, that is, the grease is below the elastic scraping strip. In this state, it is convenient to use the cleaning component to clean the grease on the elastic scraping strip.

[0030] (3) By setting the U-shaped frame, when the connecting block moves, the U-shaped frame moves synchronously, causing the U-shaped frame to perform secondary cleaning on the tooth groove after the initial grease cleaning and clean the top and bottom surfaces of the inner ring of the slewing bearing, that is, the U-shaped frame and the inclined part cooperate to clean the grease on the inner ring tooth groove, top and bottom of the slewing bearing at the same time, avoiding the situation of grease residue.

[0031] (4) The driving cylinder adjusts the distance between the first scraping mechanism and the tooth groove of the slewing bearing. When the second scraping mechanism and the first scraping mechanism are adjusted to the appropriate positions, the spring pulls the bearing block to slide on the outer side wall of the connecting rod through its own elastic performance, and the bearing block drives the U-shaped frame to be stuck inside the tooth groove of the slewing bearing. As the inner ring of the slewing bearing rotates, the spring continuously pulls the bearing block and the U-shaped frame, causing the inner wall of the U-shaped frame to always slide inside the tooth groove of the slewing bearing with the inclined part as the guiding inclined surface, gradually switching the tooth grooves after the initial cleaning, and the inner top wall and inner bottom wall of the U-shaped frame cooperate to scrape the grease on the top and bottom of the inner ring of the slewing bearing, thereby improving the cleaning effect.

[0052] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the drawings and in combination with the embodiments.

[0053] It should be pointed out that unless otherwise specified, all technical and scientific terms used in the present application have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present application belongs.

[0054] Please refer to Figures 1 - 13 , the present invention provides the following technical solutions:

[0055] Embodiment 1, a swing bearing tooth groove oiling device with a synchronous cleaning function, including a base 1, an oiling component 2 and a positioning component 3. The oiling component 2 is installed on one side of the top of the base 1, and the positioning component 3 is installed on the other side of the top of the base 1. The positioning component 3 is used for horizontally positioning the swing bearing. The oiling component 2 is suitable for oiling the tooth grooves of the swing bearing after positioning. The specific structure of the positioning component 3 is as follows:

[0056] Refer to Figure 1 and Figure 4 , the positioning component 3 includes four groups of supports 31 installed on the top of the base 1 and a fixed disk 33 arranged between the four groups of supports 31. A positioning cylinder 32 is horizontally installed on the side wall of each support 31. The positioning cylinder 32 faces the fixed disk 33 and is located above the fixed disk 33. The fixed disk 33 is supported by the cooperation of the four positioning cylinders 32 and the four groups of supports 31, so as to maintain its horizontal state.

[0057] Refer to Figures 3 - 6 , an L-shaped plate 34 for positioning the outer ring of the swing bearing is arranged equidistantly around the top of the fixed disk 33. The bottom of the L-shaped plate 34 is clamped on the inner ring of the fixed disk 33. The four positioning cylinders 32 are arranged corresponding to the four L-shaped plates 34. The end of the piston rod of the positioning cylinder 32 penetrates through the corresponding L-shaped plate 34 and is connected with a bearing platform 35. The side wall and the inner bottom wall of the bearing platform 35 are attached to the side wall and the bottom surface of the outer ring of the swing bearing. When the swing bearing needs to be positioned, the outer ring of the swing bearing is placed on the four bearing platforms 35, and then the bearing platform 35 is pushed by the positioning cylinder 32 towards the swing bearing, so as to horizontally position the swing bearing and facilitate subsequent cleaning and oiling operations.

[0058] Refer to Figure 4, a rotating assembly 4 is installed on the top of the base 1 and between four groups of supports 31. The rotating assembly 4 is connected to the inner ring of the slewing bearing tooth groove. The rotating assembly 4 is suitable for driving the rotation of the inner ring of the slewing bearing tooth groove. The specific structure of the rotating assembly 4 is as follows:

[0059] Refer to Figure 4 , in this embodiment, the rotating assembly 4 includes four frames 44 installed equidistantly around the top of the base 1. A second ratchet 46 is rotatably connected to the side wall of each frame 44. The second ratchet 46 meshes with the bottom of the first ratchet 41. A rotating motor 45 is installed on the side wall of one of the frames 44. The output end of the rotating motor 45 is connected to a second ratchet 46. The rotating motor 45 is used to drive the corresponding second ratchet 46 to rotate.

[0060] Refer to Figure 4 and Figure 5 , the rotating assembly 4 further includes a first ratchet 41 horizontally arranged below the fixed disk 33. Four limit frames 42 are arranged equidistantly around the top of the first ratchet 41. A hook 43 is connected between the top of the limit frame 42 and the bottom of the inner ring of the slewing bearing. When the rotating motor 45 drives the corresponding second ratchet 46 to rotate, the second ratchet 46 drives the first ratchet 41 to rotate. Since the first ratchet 41 is meshed at multiple points through four second ratchets 46, the first ratchet 41 rotates under the driving force, and the four second ratchets 46 assist in supporting the rotating first ratchet 41. When the first ratchet 41 rotates, it drives the corresponding four limit frames 42 and hooks 43 to displace synchronously, thereby pulling the inner ring of the slewing bearing to rotate. Since the tooth groove of the slewing bearing is arranged at the inner ring position, the tooth groove rotates and displaces synchronously when the inner ring rotates. This motion state facilitates subsequent degreasing and oiling operations.

[0061] The specific structure of the oiling assembly 2 is as follows:

[0062] Refer to Figure 1 and Figure 2, in this embodiment, the oiling assembly 2 includes a support platform 21 installed on one side of the top of the base 1 and a first electric slide rail 22 horizontally installed on the top of the support platform 21. A slide table 23 is slidably connected to the top of the first electric slide rail 22. One side of the slide table 23 extends to one end of the first electric slide rail 22 and is installed with a second electric slide rail 24. The second electric slide rail 24 is vertically installed. Both the first electric slide rail 22 and the second electric slide rail 24 are stepper motor linear slide rail slider modules, that is, the stepper motor is used to drive the rotation of the lead screw in the linear slide rail, and then drive the slider threadedly connected to the lead screw to move horizontally. The slide table 23 is connected to the slider of the first electric slide rail 22. When the slider of the first electric slide rail 22 moves, the slide table 23 will move synchronously. The slide table 23 drives the second electric slide rail 24 to move synchronously in the horizontal direction. A drive motor 25 and a transmission mechanism 26 are slidably installed on the side of the second electric slide rail 24 away from the slide table 23. The output end of the drive motor 25 is connected to the input end of the transmission mechanism 26. The output end of the transmission mechanism 26 is vertically installed with an oil injection box 27. An oiling head 28 is installed through the bottom of the oil injection box 27. The drive motor 25 and the transmission mechanism 26 are installed on the slider of the second electric slide rail 24. When the slider of the second electric slide rail 24 moves, it drives the drive motor 25 and the transmission mechanism 26 to move vertically. Through the cooperation of the first electric slide rail 22 and the second electric slide rail 24, the oil injection box 27 and the oiling head 28 installed on the transmission mechanism 26 are driven to move synchronously, so that the oiling head 28 can adapt to the position of the tooth groove of the inner ring of the slewing bearing. When the inner ring of the slewing bearing rotates, the oiling head 28 applies grease to the tooth groove of the inner ring of the slewing bearing.

[0063] At the same time, the transmission mechanism 26 is composed of a box body, a driving wheel, a driven wheel and a synchronous belt. The output end of the drive motor 25 is connected to the driving wheel, and the oil injection box 27 is connected to the driven wheel. When the drive motor 25 drives the driving wheel to rotate, the driving wheel applies the driving force to the synchronous belt, and the synchronous belt transmits the driving force to the driven wheel, so that the driven wheel, the oil injection box 27 and the oiling head 28 rotate synchronously, so that the oiling head 28 can rotate automatically when applying oil to the tooth groove of the inner ring of the slewing bearing, thereby avoiding the situation of dryness or wear of the oiling head 28 at the same position when applying oil.

[0064] While the slewing bearing is being oiled, the residual grease inside the tooth groove is cleaned by the cooperation of a manipulator, a scraper and a cleaning block.

[0065] Embodiment 2. In the existing cleaning method, during the operation process, grease is likely to accumulate on the spatula. This grease covers the entire surface of the spatula, and a large area of the spatula is contaminated. If it is necessary to avoid grease residue when the spatula cleans the next tooth groove, the spatula needs to be cleaned repeatedly. If it is not cleaned in time, the tooth groove will be secondarily contaminated due to the grease accumulated on the spatula, leaving grease and impurities inside the tooth groove. Moreover, during the cleaning process of the spatula, the cleaning may not be thorough due to the contamination of the cleaning cloth or excessive grease accumulation on the spatula. These residues will affect the entire cleaning process and the cleaning effect.

[0066] Therefore, an oil scraping assembly 5 is installed on the top of the base 1 and between two groups of supports 31. The oil scraping assembly 5 is used to remove oil from the inner tooth groove of the slewing bearing tooth groove. The specific structure of the oil scraping assembly 5 is as follows:

[0067] Refer to Figure 7 , the oil scraping assembly 5 includes a fixing frame 51 connected to the base 1, a connecting block 53 and a fixing plate 54 arranged on the side of the fixing frame 51 close to the fixing disk 33. A driving cylinder 52 is horizontally installed on one side of the fixing frame 51. The piston rod of the driving cylinder 52 is connected to the side wall of the connecting block 53. The driving cylinder 52 is used to drive the connecting block 53 and the fixing plate 54 to displace synchronously, so as to make the connecting block 53 and the fixing plate 54 displace at the top of the slewing bearing.

[0068] Refer to Figure 7 、 Figure 8 、 Figure 11 and Figure 12 , a second scraping mechanism 56 is installed on the side wall of the fixing plate 54. The driving cylinder 52 is suitable for adjusting the distance between the second scraping mechanism 56 and the slewing bearing tooth groove. The second scraping mechanism 56 includes a scraper 562 that displaces in the vertical direction. The second scraping mechanism 56 is suitable for initially scraping oil from the inside of the slewing bearing tooth groove. The specific structure of the second scraping mechanism 56 is as follows:

[0069] Refer to Figure 7 、 Figure 8 、 Figure 11 and Figure 12The second scraping mechanism 56 includes a lifting cylinder 561 vertically mounted on the side wall of the fixed plate 54. The bottom of the piston rod of the lifting cylinder 561 is connected to the scraper 562. Two scraping blocks 563 are symmetrically installed on one side of the scraper 562 close to the inner ring of the slewing bearing. The size of the scraping blocks 563 is larger than the spacing between adjacent tooth grooves of the slewing bearing. The bottom of the two scraping blocks 563 is connected to an elastic scraping strip 564. The bottom of the elastic scraping strip 564 is installed with a wedge-shaped protrusion. When one of the tooth grooves of the slewing bearing moves to the right below the scraper 562, the lifting cylinder 561 pushes the scraper 562 to move upward. The knife 562 moves downward, and the scraper 562 drives the two scraping blocks 563 to move downward. The tooth groove of the slewing bearing adaptively squeezes the elastic scraping strip 564 at the bottom of the scraping block 563, causing the elastic scraping strip 564 to bend and fit against the side wall of the scraping block 563, and the wedge-shaped protrusion arranged at the bottom of the elastic scraping strip 564 is moved to the side wall position of the scraping block 563 through the bending of the elastic scraping strip 564. In this state, the wedge-shaped protrusion is tightly fitted against the side wall of the tooth groove of the slewing bearing. During the scraping process, grease only exists in the position below the wedge-shaped protrusion until the grease is completely scraped out.

[0070] See also Figure 3 and Figure 13 A cleaning assembly 6 is installed on the top of the base 1 and between the four supports 31. The cleaning assembly 6 is located directly below the scraper 562. The cleaning assembly 6 includes a cleaning frame installed on the top of the base 1. Two rollers 61 are installed on the top of the cleaning frame. A cleaning cloth 62 is connected to the two rollers 61 by transmission. One of the rollers 61 is used to unwind the cleaning cloth 62, and the other roller 61 is used to rewind the cleaning cloth 62. When the scraper block 563 moves to the lower position inside the slewing bearing tooth groove, the wedge-shaped protrusion is aligned with the top of the cleaning cloth 62. The side wall of the winding roller 61 is connected to an external drive, which may be a servo motor and is not specifically limited here. The external drive drives the winding roller 61 to rotate, causing the cleaning cloth 62 to be pulled out from the unwinding winding roller 61 and wound up by the winding roller 61. The cleaning cloth 62 is wiped on the bottom of the scraper block 563, causing the grease on the elastic scraper strip 564 and the wedge-shaped protrusion at the bottom of the scraper block 563 to be taken away, thereby ensuring that the cleaning cloth 62 is in a clean state when in contact with the elastic scraper strip 564 and the wedge-shaped protrusion, thereby avoiding secondary contamination.

[0071] When the scraper block 563 protrudes from under the slewing support tooth groove until the elastic scraper strip 564 is separated from the slewing support tooth groove, the elastic scraper strip 564 returns to a horizontal state, that is, the grease is under the elastic scraper strip 564. In this state, the cleaning component 6 can be used to conveniently clean the grease on the elastic scraper strip 564.

[0072] Embodiment 3. After the grease is scraped out of the tooth groove, part of the grease will be directly pushed away, while the other part of the grease will be pushed onto the bottom surface of the inner ring of the slewing bearing. At the same time, the grease on the top surface of the slewing bearing needs to be cleaned separately, and cleaning the bottom surface or the top surface alone will cause secondary pollution in the tooth groove.

[0073] Refer to Figure 7 and Figure 9 , therefore, a first scraping mechanism 55 is provided on the side wall of the connecting block 53. The first scraping mechanism 55 includes a U-shaped frame 554 that is clamped with the tooth groove of the slewing bearing. When the connecting block 53 moves, the U-shaped frame 554 moves synchronously, causing the U-shaped frame 554 to perform secondary cleaning on the tooth groove after preliminary cleaning of the grease and cleaning the grease on the top and bottom surfaces of the inner ring of the slewing bearing.

[0074] Refer to Figures 7 - 10 , a groove is formed on the side wall of the connecting block 53. A connecting rod 551 is horizontally connected inside the groove. A spring 552 is sleeved outside the connecting rod 551. One end of the spring 552 is connected to the inner wall of the groove. A bearing block 553 is slidably connected to the outer side wall of the connecting rod 551. One side of the bearing block 553 is connected to one end of the spring 552. There are two groups of U-shaped frames 554, and both groups of U-shaped frames 554 are installed on the side of the bearing block 553 close to the connecting block 53. A gap is provided between the two groups of U-shaped frames 554. An inclined portion 555 is formed on the inner wall of the U-shaped frame 554. The driving cylinder 52 is suitable for adjusting the distance between the first scraping mechanism 55 and the tooth groove of the slewing bearing. When the second scraping mechanism 56 is adjusted to the adapted position, the spring 552 pulls the bearing block 553 to slide on the outer side wall of the connecting rod 551 through its own elastic performance, and the bearing block 553 drives the U-shaped frame 554 to be stuck inside the tooth groove of the slewing bearing. As the inner ring of the slewing bearing rotates, the spring 552 continuously pulls the bearing block 553 and the U-shaped frame 554, causing the inner wall of the U-shaped frame 554 to always slide inside the tooth groove of the slewing bearing through the inclined portion 555 as a guiding inclined surface, gradually switching the tooth grooves after the initial cleaning, and the inner top wall and inner bottom wall of the U-shaped frame 554 cooperate to scrape the grease on the top and bottom of the inner ring of the slewing bearing, that is, the U-shaped frame 554 and the inclined portion 555 cooperate to clean the grease in the tooth groove, on the top and bottom of the inner ring of the slewing bearing at the same time, avoiding the situation of grease residue. On the contrary, after the cleaning is completed, the U-shaped frame 554 is pushed away from the slewing bearing by the driving cylinder 52. In this state, only the grease inside the U-shaped frame 554 and the last tooth groove of the slewing bearing needs to be removed.
