Description

Technical Field

[0001] The present invention relates to the technical field of motor end - cover processing, and more specifically, it relates to a comprehensive machine for pressing bearings and applying glue to motor end - covers. Background Art

[0002] The motor end - cover is a key component of the motor, which is used to fix and support the motor shaft, protect the internal components, and play a role in sealing and dust - proofing. It is usually made of cast iron, cast steel or aluminum alloy, with good strength and wear resistance. Pressing the bearing and applying glue are important steps in the motor assembly process. Pressing the bearing firmly installs the bearing into the bearing chamber of the motor end - cover to ensure the stable operation of the motor. Applying glue to the motor end - cover is to ensure the sealing between the end - cover and the motor, preventing dust and moisture from entering the motor interior.

[0003] Currently, the operation method for pressing the bearing and applying glue to the motor end - cover is as follows: First, place the motor end - cover on the workbench, then grab the bearing and press it into the bearing chamber in the middle of the motor end - cover. At the same time, apply sealant to the outer ring of the motor end - cover. To enhance the strength of the end - cover and prevent lubricating oil leakage, before pressing the bearing, a glue - throwing machine is used to evenly throw glue into the bearing chamber, and then the bearing is accurately pressed in.

[0004] However, since the glue is first applied to the inside of the bearing chamber and the direction of the bearing entering the inside of the motor end - cover is limited, during the process of pressing the bearing into the motor end - cover, the glue is easily squeezed and pushed into the bearing chamber, and then accumulates at the end position of the bearing chamber. This method will cause the glue to squeeze into the position of the bearing balls, affecting the normal operation of the bearing. Summary of the Invention

[0005] Aiming at the deficiencies of the existing technology, the purpose of the present invention is to provide a comprehensive machine for pressing bearings and applying glue to motor end - covers.

[0006] To achieve the above purpose, the present invention provides the following technical solution: A comprehensive machine for pressing bearings and applying glue to motor end - covers, including a main body assembly. The main body assembly includes a workbench, a placement table installed on one side of the top of the workbench, and an electric turntable installed on the top of the placement table. The top of the electric turntable is provided with an end - cover.

[0007] A first glue - applying component is installed on the top of the workbench. The first glue - applying component includes a carrier frame installed on the top of the workbench and a servo motor installed at the bottom of the carrier frame. The output end of the servo motor is connected to a swing arm. At the bottom of one end of the swing arm, a glue - applying motor is installed. The output end of the glue - applying motor is connected to a cylinder body. A ring body is connected to the outer side wall of the cylinder body. A plurality of glue - applying holes are equidistantly arranged on the outer wall of the cylinder body and above the ring body.

[0008] One side of the workbench is provided with a grasping component and a material pressing component, and on the top of the placing table and on one side of the end cover, a second glue coating component and a cleaning component are provided.

[0009] The present invention is further configured as follows: The grasping component is located between the material pressing component and the workbench. The grasping component includes two legs arranged on one side of the workbench. At the top of the two legs, a first electric slide rail is installed. On one side of the first electric slide rail, a second electric slide rail is slidably connected. On one side of the second electric slide rail, a telescopic cylinder is slidably connected. At the end of the piston rod of the telescopic cylinder, a clamping cylinder is installed.

[0010] By adopting the above technical solution, the servo motor drives the swing arm to swing, so that the cylinder body fits the outer wall of the bearing, and the glue flows out through the glue coating hole and is evenly coated on the outer wall of the bearing. The glue coating motor drives the cylinder body to rotate slowly to ensure that the glue is evenly rolled and coated. After the glue coating is completed, the grasping component moves the bearing above the end cover and places it. Subsequently, the material pressing component presses the bearing into the end cover. This method of pressing the bearing can ensure that the glue will not flow and accumulate inside the end cover.

[0011] The telescopic cylinder and the clamping cylinder can move to an external placement rack to grasp the bearing. After the bearing is grasped, the first electric slide rail and the second electric slide rail are used in cooperation to move the bearing above the end cover. Then, the telescopic cylinder drives the clamping cylinder and the bearing to move directly above the bearing chamber of the end cover. Then, the second electric slide rail controls the bearing to move downward. Then, the clamping cylinder loosens and resets the bearing, and subsequently, the bearing can be pressed into the bearing chamber of the end cover by the material pressing component.

[0012] The present invention is further configured as follows: The material pressing component includes a vertical frame arranged on the side of the first electric slide rail away from the workbench and a bracket installed on the side wall of the vertical frame. At the top of the bracket, a lifting cylinder is vertically installed. At the bottom end of the piston rod of the lifting cylinder, a moving frame is connected. At the bottom of the moving frame, a pressing rod is vertically installed.

[0013] The present invention is further configured as follows: The second glue coating component includes a vertical plate installed on one side of the top of the placing table. The side wall of the vertical plate is connected with a fixing rod. On the outer side wall of the fixing rod, an adjusting frame is installed. On the side wall of the adjusting frame, a glue coating cylinder is installed. At the end of the piston rod of the glue coating cylinder, a positioning frame is connected. On the side of the positioning frame away from the glue coating cylinder, a glue discharging head is installed.

[0014] By adopting the above technical solution, the lifting cylinder drives the moving frame and the pressing rod to move up and down. Before the bearing is placed on the top of the end cover, first, the glue is spun onto the inner wall of the bearing chamber of the end cover by an external glue spinner, and then the bearing is placed. After the placement is completed, the lifting cylinder drives the moving frame and the pressing rod to move down, so that the bearing can be pressed into the bearing chamber on the end cover. The adjusting frame can rotate on the outer wall of the fixed rod, thereby adjusting the angle of the adjusting frame, so that the glue discharging head can face the outer wall of the end cover. Then, the glue applying cylinder drives the positioning frame and the glue discharging head to move, so that the glue discharging head fits on the position of the outer wall of the end cover that needs to be coated with glue. After that, the adjusting frame is fixed by a locking screw. After the adjustment is completed, the external glue supply device discharges the glue through the glue discharging head. At the same time, the electric turntable can drive the end cover to rotate, which is convenient for applying glue to the end cover. And during the rotary glue application process, the bearing can be pressed into the end cover at the same time, that is, the pressing rod fits on the top of the inner ring of the bearing, so that when the end cover rotates, the end cover and the outer ring of the bearing are mutually extruded and rotate synchronously, so that the bearing is pressed into the inside of the end cover without affecting the rotation of the end cover.

[0015] The present invention is further configured as: the cleaning assembly includes a third electric slide rail installed on the top of the placement table and a fourth electric slide rail slidably connected to the top of the third electric slide rail. The fourth electric slide rail is vertically arranged. An L-shaped plate is slidably connected to the side wall of the fourth electric slide rail. A cleaning motor is installed on the top of the L-shaped plate. The output end of the cleaning motor penetrates through the L-shaped plate and is connected to a rotating plate. Two auxiliary motors are installed on the top of the rotating plate. A glue scraping mechanism and a glue cleaning mechanism are arranged at the bottom of the rotating plate. The glue scraping mechanism and the glue cleaning mechanism are arranged corresponding to the two auxiliary motors.

[0016] The present invention is further configured as: the glue scraping mechanism includes a mounting seat installed at one end of the bottom of the rotating plate. A plate body is rotatably connected to the bottom of the mounting seat. One of the auxiliary motors is connected to the plate body. Four U-shaped scraping plates are circumferentially connected to the bottom of the plate body.

[0017] The present invention is further configured as: an inclined portion is provided on the inner wall of each U-shaped scraping plate, and a stop block is arranged on the side wall of the U-shaped scraping plate.

[0018] The present invention is further configured as: the U-shaped scraping plate is hollow, and a plurality of through holes are equidistantly arranged on the inclined portion.

[0019] The present invention is further configured as: the glue cleaning mechanism includes a cross installed at the bottom of the rotating plate and far away from the glue scraping mechanism. Four swing rods are swingably connected to the side wall of the cross. Cleaning blocks are arranged at the ends of the four swing rods.

[0020] The present invention is further configured such that: a worm gear is rotatably connected to a side wall of the cross and at a position corresponding to the swing rod, the worm gear is connected to the corresponding swing rod, a glue cleaning cylinder is hingedly installed on the side wall of each swing rod, the end of the piston rod of the glue cleaning cylinder is hingedly connected to the corresponding cleaning block, and the cleaning block is hingedly connected to the bottom end of the corresponding swing rod. A driving space is formed in the middle of the cross, and all four crosses extend into the driving space. A worm is rotatably connected inside the driving space, the worm is connected to the output end of the corresponding auxiliary motor, and the worm meshes with the four worm gears.

[0021] By adopting the above technical solution, when the glue scraping mechanism cleans the glue on the surface of the bearing, the U-shaped scraper fits the surface of the bearing, the auxiliary motor drives the plate body to rotate, so that the scraper scrapes on the surface of the bearing, the opening of the scraper faces the rotation direction, and the inclined part scrapes up the glue and collects it inside the scraper. When the glue accumulates on the inclined part, it flows into the scraper through the through hole for collection, ensuring that the overflowing glue does not contaminate the bearing.

[0022] When the end cover needs glue cleaning, the cleaning motor drives the rotating plate to rotate, so that the glue scraping mechanism and the glue cleaning mechanism are alternately displaced, and the glue cleaning mechanism is moved above the end cover. Subsequently, the electric slide rail drives the L-shaped plate and related components to move downwards, so that the glue cleaning mechanism penetrates into the bearing chamber of the end cover, and the distance between the cleaning blocks is adjusted to fit the inner wall of the end cover. When the end cover rotates, the cleaning blocks scrape the glue by rubbing against the inner wall. By adjusting the distance between the cleaning blocks multiple times, the glue removal requirements for the stepped side wall of the bearing chamber of the end cover are met.

[0023] By setting the glue cleaning cylinder, the glue cleaning cylinder pushes the cleaning block to swing, and the cleaning block is adjusted to an inclined state, which is convenient for removing glue from the inner fillet position of the bearing chamber of the end cover. The cleaning block continues to swing to a vertical state, which is convenient for removing glue from the inner bottom wall position of the bearing chamber of the end cover. This design meets the glue removal requirements for different sizes, fillets and cross-sections of the end cover.

[0024] In summary, the present application includes at least one of the following beneficial technical effects:

[0025] (1) By setting the cylinder body, the servo motor drives the swing arm to swing, so that the cylinder body fits the outer wall of the bearing, the glue flows out through the glue application hole and is evenly coated on the outer wall of the bearing. The glue application motor drives the cylinder body to rotate slowly to ensure uniform rolling coating of the glue. After the glue application is completed, the grasping component moves the bearing above the end cover and places it. Subsequently, the pressing component presses the bearing into the end cover, and the bearing and the end cover squeeze the glue, and the glue flows outwards along the outer ring of the bearing. This way of pressing the bearing can ensure that the glue does not flow and accumulate inside the end cover.

[0026] (2) By setting a U-shaped squeegee, when the glue scraping mechanism cleans the glue on the bearing surface, the U-shaped squeegee fits the bearing surface. The auxiliary motor drives the plate body to rotate, causing the squeegee to scrape on the bearing surface. The opening of the squeegee faces the rotation direction, and the inclined part scrapes up the glue and collects it inside the squeegee. When the glue accumulates on the inclined part, it flows into the inside of the squeegee through the through hole for collection, ensuring that the overflowing glue does not contaminate the bearing.

[0027] (3) When the end cap needs to be cleaned of glue, the cleaning motor drives the rotating plate to rotate, causing the glue scraping mechanism and the glue cleaning mechanism to alternately displace. The glue cleaning mechanism is moved above the end cap. Subsequently, the electric slide rail drives the L-shaped plate and related components to move downwards, enabling the glue cleaning mechanism to penetrate into the bearing chamber of the end cap. The distance between the cleaning blocks is adjusted to fit the inner wall of the end cap. When the end cap rotates, the cleaning blocks rub against the inner wall to scrape off the glue. By adjusting the distance between the cleaning blocks multiple times, the glue removal requirements for the stepped side walls of the bearing chamber of the end cap are met.

[0028] (4) By setting a glue cleaning cylinder, the glue cleaning cylinder pushes the cleaning block to swing. The cleaning block is adjusted to an inclined state, facilitating glue removal at the internal rounded corner position of the bearing chamber of the end cap. The cleaning block continues to swing to a vertical state, facilitating glue removal at the internal bottom wall position of the bearing chamber of the end cap. This design meets the glue removal requirements for different sizes, rounded corners, and cross-sections of the end cap. Brief Description of the Drawings

[0048] It should be noted that, without conflict, the embodiments and features in the embodiments of the present application may 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.

[0049] 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.

[0050] Please refer to Figures 1 - 10 , the present invention provides the following technical solutions:

[0051] Example 1, refer to Figure 1, A comprehensive machine for pressing bearings and applying glue to the motor end cover, including a main body assembly 1. The main body assembly 1 includes a workbench 11, a placement table 12 installed on one side of the top of the workbench 11, and an electric turntable 13 installed on the top of the placement table 12. The top of the electric turntable 13 is provided with an end cover 7. The electric turntable 13 is used to carry the end cover 7 and can drive the end cover 7 to rotate, thus facilitating the application of glue and bearing pressing to the end cover 7.

[0052] Refer to Figure 1 , On one side of the workbench 11, there is a grasping component 2 and a material pressing component 3. The grasping component 2 is located between the material pressing component 3 and the workbench 11. The grasping component 2 is used to grasp the bearing and transfer the bearing to be placed above the end cover 7. The material pressing component 3 is used to press the bearing into the interior of the end cover 7. The specific structure of the grasping component 2 is as follows:

[0053] Refer to Figure 2 , The grasping component 2 includes two legs 21 arranged on one side of the workbench 11. The top of the two legs 21 is installed with a first electric slide rail 22. One side of the first electric slide rail 22 is slidably connected with a second electric slide rail 23. One side of the second electric slide rail 23 is slidably connected with a telescopic cylinder 24. The end of the piston rod of the telescopic cylinder 24 is installed with a clamping cylinder 25. The first electric slide rail 22 is used to drive the second electric slide rail 23 to slide horizontally. The second electric slide rail 23 is used to drive the telescopic cylinder 24 and the clamping cylinder 25 to slide in the vertical direction. This adjustment method can control the displacement of the telescopic cylinder 24 and the clamping cylinder 25. The telescopic cylinder 24 is used to drive the clamping cylinder 25 to expand and contract in the horizontal direction. The clamping cylinder 25 is used to clamp the bearing from the inner ring position.

[0054] Specifically, the telescopic cylinder 24 and the clamping cylinder 25 can move to an external placement rack to grasp the bearing. After the bearing is grasped, the first electric slide rail 22 and the second electric slide rail 23 are used in cooperation to move the bearing above the end cover 7. Then, the telescopic cylinder 24 drives the clamping cylinder 25 and the bearing to move directly above the bearing chamber of the end cover 7. Then, the second electric slide rail 23 controls the bearing to move down. Then, the clamping cylinder 25 releases the bearing and resets. Subsequently, the bearing can be pressed into the bearing chamber of the end cover 7 through the material pressing component 3.

[0055] Refer to Figure 2 , The specific structure of the material pressing component 3 is as follows:

[0056] The blanking component 3 includes a vertical frame 31 disposed on the side of the first electric slide rail 22 away from the workbench 11 and a bracket 32 mounted on the side wall of the vertical frame 31. A lifting cylinder 33 is vertically installed at the top of the bracket 32. The bottom end of the piston rod of the lifting cylinder 33 is connected to a moving frame 34. A pressing rod 35 is vertically installed at the bottom of the moving frame 34. The vertical frame 31 and the bracket 32 form a main frame. The lifting cylinder 33 is used to drive the moving frame 34 and the pressing rod 35 to move up and down. Before the bearing is placed on the top of the end cover 7, first, glue is applied to the inner wall of the bearing chamber of the end cover 7 by an external spin coater, and then the bearing is placed. After the placement is completed, the lifting cylinder 33 is used to drive the moving frame 34 and the pressing rod 35 to move down, so that the bearing can be pressed into the bearing chamber on the end cover 7.

[0057] Refer to Figure 1 and Figure 6 , on the top of the placement table 12 and on one side of the end cover 7, a second glue application component 5 is provided. The second glue application component 5 is used to apply sealant to the outer wall of the end cover 7 to improve the sealing performance when the end cover 7 is connected to the motor housing. The specific structure of the second glue application component 5 is as follows:

[0058] Refer to Figure 1 and Figure 6 , the second glue application component 5 includes a vertical plate 51 installed on one side of the top of the placement table 12. A fixed rod 52 is connected to the side wall of the vertical plate 51. An adjusting frame 53 is installed on the outer side wall of the fixed rod 52. A glue application cylinder 54 is installed on the side wall of the adjusting frame 53. The end of the piston rod of the glue application cylinder 54 is connected to a positioning frame 55. A glue discharging head 56 is installed on the side of the positioning frame 55 away from the glue application cylinder 54. The adjusting frame 53 can rotate on the outer wall of the fixed rod 52 to adjust the angle of the adjusting frame 53, so that the glue discharging head 56 can face the outer wall of the end cover 7. Then, the glue application cylinder 54 is used to drive the positioning frame 55 and the glue discharging head 56 to move, so that the glue discharging head 56 fits on the position of the outer wall of the end cover 7 that needs to be glued. After that, the adjusting frame 53 is fixed with a locking screw. After the adjustment is completed, an external glue supply device discharges the glue through the glue discharging head 56. At the same time, the electric turntable 13 can drive the end cover 7 to rotate, which is convenient for applying glue to the end cover 7. And during the rotary glue application process, the bearing can be pressed into the end cover 7 at the same time, that is, the pressing rod 35 fits on the top of the inner ring of the bearing, so that when the end cover 7 rotates, the end cover 7 and the outer ring of the bearing are mutually extruded and rotate synchronously, so that the bearing is pressed into the inside of the end cover 7 without affecting the rotation of the end cover 7.

[0059] In the second embodiment, since the glue is first applied to the inside of the bearing chamber and the direction in which the bearing enters the inside of the end cover 7 is limited, during the process of pressing the bearing by the end cover 7, the glue is easily squeezed and pushed into the bearing chamber, and then accumulates at the end of the bearing chamber. This method will cause the glue to squeeze into the position of the bearing balls, affecting the normal operation of the bearing.

[0060] Therefore, a first glue - applying assembly 4 is installed on the top of the workbench 11. The first glue - applying assembly 4 is used to apply glue on the outer wall of the bearing, while no glue is applied inside the bearing chamber of the end - cover 7. That is, when the glued bearing is pressed into the bearing chamber of the end - cover 7, the glue is extruded and flows to the outside of the end - cover 7, not into the inside of the end - cover 7, avoiding the situation that the glue accumulates at the end position of the bearing chamber and contaminates the bearing. The specific structure of the first glue - applying assembly 4 is as follows:

[0061] Refer to Figures 3 - 5 , the first glue - applying assembly 4 includes a carrier 41 installed on the top of the workbench 11 and a servo - motor 47 installed at the bottom of the carrier 41. The output end of the servo - motor 47 is connected to a swing arm 42. At the bottom of one end of the swing arm 42, a glue - applying motor 43 is installed. The output end of the glue - applying motor 43 is connected to a cylinder body 44. A ring body 45 is connected to the outer side wall of the cylinder body 44. A plurality of glue - applying holes 46 are equidistantly arranged on the outer wall of the cylinder body 44 and above the ring body 45. When the clamping cylinder 25 clamps the bearing and transfers it to the position of the first glue - applying assembly 4, the outer ring of the bearing fits on the ring body 45. The ring body 45 is used to perform a preliminary positioning function on the bearing. The servo - motor 47 is used to drive the swing arm 42 to swing, so that the cylinder body 44 can fit on the outer wall of the bearing. The supply pipe of the external glue - supply device is communicated with the cylinder body 44. That is, the external glue - supply device supplies glue into the cylinder body 44 through the supply pipe. Then the glue flows out through the glue - applying holes 46, so that the glue is applied to the outer wall of the bearing. Subsequently, the glue - applying motor 43 is used to drive the cylinder body 44 to rotate slowly, so that the cylinder body 44 rolls the glue onto the outer wall of the bearing. After the bearing is glued, the grasping assembly 2 transfers the bearing to be placed above the end - cover 7, and then the bearing is pressed into the inside of the end - cover 7 through the pressing component 3. This way of pressing the bearing can ensure that the glue does not flow and accumulate into the inside of the end - cover 7.

[0062] However, the method of applying glue on the outer wall of the bearing and then pressing the bearing into the bearing chamber will still cause the glue to be extruded from the end of the bearing far from the bearing chamber, resulting in glue overflow.

[0063] Therefore, refer to Figure 1 , a cleaning assembly 6 is arranged on the top of the placing table 12 and on one side of the end - cover 7. The cleaning assembly 6 is used to clean the glue overflowing from the end of the bearing far from the bearing chamber. The specific structure of the cleaning assembly 6 is as follows:

[0064] Refer to Figures 7 - 9, the cleaning component 6 includes a third electric slide rail 61 installed on the top of the placement table 12 and a fourth electric slide rail 62 slidably connected to the top of the third electric slide rail 61. The fourth electric slide rail 62 is vertically arranged, and an L-shaped plate 63 is slidably connected to the side wall of the fourth electric slide rail 62. A cleaning motor 64 is installed on the top of the L-shaped plate 63. The output end of the cleaning motor 64 penetrates through the L-shaped plate 63 and is connected to a rotating plate 65. Two auxiliary motors 66 are installed on the top of the rotating plate 65. A glue scraping mechanism 67 is arranged at the bottom of the rotating plate 65. The glue scraping mechanism 67 is arranged corresponding to one of the auxiliary motors 66. The third electric slide rail 61 is used to drive the fourth electric slide rail 62 to move horizontally, and the fourth electric slide rail 62 is used to drive the L-shaped plate 63 to move up and down, thereby adjusting the displacement of the cleaning motor 64, the rotating plate 65 and the glue scraping mechanism 67. That is, when the bearing pressing operation is completed, through the cooperation of the third electric slide rail 61 and the fourth electric slide rail 62, the glue scraping mechanism 67 is moved above the bearing and the glue scraping mechanism 67 is attached to the top of the bearing. The glue scraping mechanism 67 is used to clean the glue overflowing from one end of the bearing away from the bearing chamber. The specific structure of the glue scraping mechanism 67 is as follows:

[0065] Refer to Figure 8 and Figure 9 , the glue scraping mechanism 67 includes a mounting seat 671 installed at one end of the bottom of the rotating plate 65. A plate body 672 is rotatably connected to the bottom of the mounting seat 671. One of the auxiliary motors 66 is connected to the plate body 672. Four U-shaped scraping plates 673 are circumferentially connected to the bottom of the plate body 672. An inclined portion 674 is provided on the inner wall of each U-shaped scraping plate 673. A stop block is arranged on the side wall of the U-shaped scraping plate 673. The U-shaped scraping plate 673 is hollow, and a plurality of through holes 675 are equidistantly arranged on the inclined portion 674. When the glue scraping mechanism 67 cleans the glue on the bearing surface, first, the U-shaped scraping plate 673 is attached to the bearing surface, and then the plate body 672 is driven to rotate by the corresponding auxiliary motor 66. The plate body 672 drives the four U-shaped scraping plates 673 to scrape on the bearing surface. The opening direction of the U-shaped scraping plate 673 is set towards the rotating direction. The inclined portion 674 provided on the U-shaped scraping plate 673 scrapes up the glue, and the glue remains inside the U-shaped scraping plate 673. When the glue accumulates at the position of the inclined portion 674, the glue flows into the inside of the U-shaped scraping plate 673 through the through holes 675 for collection, thereby ensuring that the overflowing glue will not contaminate the bearing.

[0066] In the third embodiment, when the bearing inside the end cover 7 is damaged, the bearing needs to be disassembled and replaced. At this time, there will be solidified glue inside the end cover 7, and the glue needs to be processed before a new bearing can be installed. The conventional cleaning method is to manually scrape the glue inside, or directly use a deburring brush to polish. However, the inside of the end cover 7 is stepped, with rounded corners, and different sizes. The conventional deburring brush cannot adapt to the size, and the side wall can be cleaned, but the end face cannot be cleaned.

[0067] Refer to Figure 7 and Figure 10 , for this purpose, a glue cleaning mechanism 68 is provided at the bottom of the rotating plate 65. The glue cleaning mechanism 68 is arranged corresponding to another auxiliary motor 66. The glue cleaning mechanism 68 is used to clean the residual glue inside the end cap 7 that needs to be repaired, facilitating the installation of a new bearing into the inside of the end cap 7. The specific structure of the glue cleaning mechanism 68 is as follows:

[0068] Refer to Figure 10 , the glue cleaning mechanism 68 includes a cross 681 installed at the bottom of the rotating plate 65 and away from one end of the glue scraping mechanism 67. Four swing rods 684 are swing-connected around the side wall of the cross 681. Cleaning blocks 685 are hinged to the ends of the four swing rods 684. A worm gear 683 is rotatably connected to the side wall of the cross 681 at a position corresponding to the swing rod 684. The worm gear 683 is connected to the corresponding swing rod 684. A driving space is opened in the middle of the cross 681, and all four cross 681 extend into the driving space. A worm 682 is rotatably connected inside the driving space. The worm 682 is connected to the output end of the corresponding auxiliary motor 66. The worm 682 meshes with the four worm gears 683. The auxiliary motor 66 corresponding to the glue cleaning mechanism 68 is used to drive the worm 682 to rotate. When the worm 682 rotates, it drives the corresponding four worm gears 683 to rotate. The worm gears 683 drive the corresponding swing rods 684 and cleaning blocks 685 to swing, thereby being able to adjust the distance between the four cleaning blocks 685 to adapt to the need for glue cleaning on the inner walls with different diameters at stepped positions inside the end cap 7.

[0069] Specifically, when the end cap 7 needs glue cleaning, the rotating plate 65 is driven to rotate by the cleaning motor 64. The rotating plate 65 drives the glue scraping mechanism 67 and the glue cleaning mechanism 68 to alternately displace, causing the glue cleaning mechanism 68 to move above the end cap 7. Then, the fourth electric slide rail 62 drives the L-shaped plate 63, the cleaning motor 64, the rotating plate 65, the glue scraping mechanism 67, and the glue cleaning mechanism 68 to move downward, causing the glue cleaning mechanism 68 to penetrate into the bearing chamber of the end cap 7. Then, by adjusting the distance between the four cleaning blocks 685, the cleaning blocks 685 are caused to fit against the inner wall position of the bearing chamber of the end cap 7. Then, the end cap 7 rotates self - sufficiently, and the cleaning blocks 685 rub on the inner wall of the bearing chamber of the end cap 7, causing the glue to be scraped off. Through multiple distance adjustments of the cleaning blocks 685, the glue removal operation on the stepped side wall of the bearing chamber of the end cap 7 is satisfied.

[0070] Refer to Figure 10, a glue cleaning cylinder 686 is hingedly installed on the side wall of each swing rod 684, and the end of the piston rod of the glue cleaning cylinder 686 is hingedly connected to the corresponding cleaning block 685. After the glue removal from the side wall of the bearing chamber of the end cover 7 is completed, the glue cleaning cylinder 686 is used to push the corresponding cleaning block 685 to swing, and the cleaning block 685 is adjusted to an inclined state. In this state, it is convenient for the cleaning block 685 to remove glue from the inner rounded corner position of the bearing chamber of the end cover 7. When the cleaning block 685 continues to swing, it is in a vertical state. In this state, it is convenient for the cleaning block 685 to remove glue from the inner bottom wall position of the bearing chamber of the end cover 7, meeting the glue removal requirements for different sizes, rounded corners, and cross-sections of the end cover 7.

[0071] After the glue removal is completed, the end cover 7 can perform the operation of pressing the bearing and applying glue through the cooperation of the grasping component 2, the material pressing component 3, the first glue application component 4, the second glue application component 5, and the cleaning component 6.

[0072] Obviously, the above-described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.
