Description

Technical Field

[0002] A bearing is an important component in modern mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. During the manufacturing process of a bearing, for a sealed bearing, grease needs to be injected between the inner and outer rings of the bearing, and then after the grease injection is completed, a cover needs to be added between the inner and outer rings of the bearing to ensure the sealing of the grease and prevent the grease from leaking out.

[0003] The existing bearing grease injection and capping machine includes a bracket. A workbench is arranged on the bracket. A bearing grease injection device and a bearing capping device are sequentially arranged on the workbench. A bearing transfer and handling device is arranged corresponding to the bearing grease injection device and the bearing capping device, which better realizes the automation of bearing grease injection and capping, reduces the high labor intensity, improves the efficiency of bearing grease injection and capping, and ensures the quality of grease injection and capping.

[0004] Although the existing bearing grease injection and capping machine realizes the positioning and commutation of the bearing through the handling device, this handling device not only occupies a large area and has a high cost, but also increases the maintenance cost of the bearing grease injection and capping machine. Moreover, during the grease injection and capping processes, the handling device needs to release the fixation of the bearing, which causes the bearing to be easily offset due to vibration or other external forces during the movement of the bearing grease injection device and the bearing capping device to the working positions, thus affecting the accuracy of grease injection and capping.

[0068] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention

[0069] The following describes the specific implementation of the present invention in detail with reference to specific embodiments

[0070] Such as Figures 1 to 10As shown in the figure, an automatic bearing greasing and capping machine provided as an embodiment of the present invention includes a machine base 100. The heights of the left and right ends of the machine base 100 are different, and the height of the left end of the machine base 100 is lower than that of the right end. Greasing mechanisms 300 and capping mechanisms 400 are provided at both the left and right ends of the machine base 100. The greasing mechanism 300 is located on one side of the capping mechanism 400, and the greasing mechanism 300 on the left end of the machine base 100 is close to the capping mechanism 400 on the right end of the machine base 100. The greasing mechanism 300 is used to grease the bearing, and the capping mechanism 400 is used to press-fit the bearing cover 700 onto the bearing. It further includes:

[0071] A spiral flipping chute 500, which is inclined and arranged in the middle of the machine base 100. The input end at the highest position of the spiral flipping chute 500 is matched with the capping mechanism 400 on the right end of the machine base 100, and the output end at the lowest position of the spiral flipping chute 500 is matched with the greasing mechanism 300 on the left end of the machine base 100. A spiral groove 510 is formed inside the spiral flipping chute 500. Through the ingeniously designed inclination angle and by utilizing the gravity of the bearing itself, the spiral flipping chute 500 can efficiently flip the bearings entering the spiral groove 510, thereby realizing the commutation process of the bearings. This not only simplifies the operation process but also enables the greasing mechanisms 300 and capping mechanisms 400 at both ends of the machine base 100 to more conveniently complete the lubrication and sealing processes on both sides of the bearings, thus greatly improving the overall automation level of the greasing and capping machine. Compared with the traditional separately used flipping device, this integrated spiral flipping chute 500 has the advantages of less occupied space, fast flipping speed, and high cost-effectiveness, significantly enhancing the practicability and working efficiency of the bearing greasing and capping machine;

[0072] A feeding mechanism 600. Two sets of the feeding mechanism 600 are respectively arranged on one side of both the left and right ends of the machine base 100. By moving along the X-axis and Y-axis, the feeding mechanism 600 can not only push the bearings that have been greased by the greasing mechanism 300 to the capping mechanism 400 for capping, but also push the bearings that have been capped by the capping mechanism 400 into the spiral flipping chute 500 for flipping and commutation, thereby facilitating the greasing mechanism 300 and capping mechanism 400 to perform lubrication and sealing processes on the other side of the bearings, realizing the full automation and continuity of the greasing and capping machine;

[0073] Positioning mechanism 200, the positioning mechanism 200 includes a workbench 210, a chute 211, a connection groove 212, a shock-absorbing base 220, a control assembly 230 and a clamping assembly 240. The bottom of the workbench 210 is fixed to the left and right ends of the machine base 100 through the shock-absorbing base 220, and the workbench 210 is respectively located directly below the grease injection mechanism 300 and the gland pressing mechanism 400 and is concentric with both. The workbench 210 is circumferentially distributed with chutes 211, and connection grooves 212 are opened on both sides of the workbench 210. A connecting plate 800 is provided between two workbenches 210 at the same height of the machine base 100. The two ends of the connecting plate 800 are respectively locked in the connection grooves 212 on the two workbenches 210 by screws. The bottom of the workbench 210 is provided with a control assembly 230. One end of the control assembly 230 is installed on the machine base 100, and the other end of the control assembly 230 is connected to the clamping assembly 240 circumferentially distributed at the bottom of the workbench 210;

[0074] The clamping assembly 240 includes a guide frame 241, a guide groove 242, a pulley 243, a connecting rod 244, a spring 245, an L-shaped rod 246, a clamping slider 247 and a clamping block 248. The guide frames 241 are equidistantly distributed at the bottom of the workbench 210 according to the distribution track of the chute 211 and are fixedly connected to the shock-absorbing base 220. The guide frames 241 are provided with guide grooves 242 with different heights at both ends. A pulley 243 is slidably installed in the guide groove 242. The pulley 243 is connected to one end of the connecting rod 244. The other end of the connecting rod 244 is connected to one end of an L-shaped rod 246 rotatably installed on the clamping slider 247. The clamping slider 247 is slidably installed in the chute 211. The other end of the L-shaped rod 246 is fixed with a clamping block 248. The connecting rod 244 is connected to the other end of the control assembly 230, and a spring 245 is installed between one side of the connecting rod 244 and the inner wall of one end of the guide groove 242;

[0075] In the initial state, the L-shaped rod 246 and the clamping block 248 are both hidden in the chute 211. The control assembly 230 pulls the connecting rod 244. The connecting rod 244 drives the pulley 243 to move in the guide groove 242. The pulley 243 can drive one end of the connecting rod 244 to move up and translate on the guide frame 241 by cooperating with the guide groove 242. As the connecting rod 244 moves upward, it can cause the L-shaped rod 246 to rotate 90 degrees on the clamping slider 247. The L-shaped rod 246 drives the clamping block 248 to rotate 90 degrees, so that the clamping block 248 is parallel to the outer wall of the bearing;

[0076] With the translation of the connecting rod 244, it can drive the clamping block 248 rotated by 90 degrees to move through the L-shaped rod 246. At the same time, the connecting rod 244 squeezes the spring 245 to make it in a state of storing energy. Multiple clamping blocks 248 work together and can push the bearing on the workbench 210 to the center of the workbench 210 and clamp and fix the bearing located at the center of the workbench 210 by moving closer to each other, which not only simplifies the operation process, but also greatly improves the efficiency and precision of the grease injection mechanism 300 and the glanding mechanism 400 when lubricating and sealing the bearing, thereby improving the working performance of the entire grease injection and glanding machine.

[0077] In this embodiment, the clamping block 248 preferably adopts a block structure made of rubber, which can effectively clamp and fix the outer wall of the bearing and will not cause additional damage to the outer wall of the bearing, ensuring the aesthetic appearance of the bearing.

[0078] As Figures 3 to 7 shown, as a preferred embodiment of the present invention, the control assembly 230 includes a positioning motor, a screw rod 231, a nut sleeve 232, a guide post 233 and a pull rope 234. The positioning motor is fixed on the machine base 100, and the screw rod 231 is fixed on the output end of the positioning motor. One end of the screw rod 231 penetrates through the shock-absorbing base 220 and is threadedly connected to the nut sleeve 232. The nut sleeve 232 is located at the bottom of the workbench 210, and the nut sleeve 232 is vertically slidably installed on the shock-absorbing base 220 through the guide post 233. The nut sleeve 232 is circumferentially distributed with pull ropes 234, and one end of the pull rope 234 penetrates through the guide frame 241 and is connected to the connecting rod 244.

[0079] In this embodiment, the positioning motor drives the screw rod 231 to rotate. The screw rod 231 can drive the nut sleeve 232 to move vertically by cooperating with the guide post 233. The nut sleeve 232 pulls the pull rope 234, and the pull rope 234 pulls the connecting rod 244, so as to complete the centering clamping and fixing of the bearing by multiple clamping blocks 248 and ensure the production precision of the bearing;

[0080] When the bearing is completed with grease injection or glanding, the positioning motor drives the screw rod 231 to rotate in the reverse direction. The screw rod 231 drives the nut sleeve 232 to move in the reverse direction. The nut sleeve 232 releases the pull rope 234. At this time, the spring 245 drives the connecting rod 244 to translate and move downward in the reverse direction through its own elastic force. With the reverse translation of the connecting rod 244, it can drive the clamping block 248 to move away from the bearing, so as to release the clamping and fixing of the bearing and make the bearing in a free state on the workbench 210;

[0081] As the connecting rod 244 moves downward, the connecting rod 244 can drive the L-shaped rod 246 and the clamping block 248 to rotate 90 degrees in the reverse direction, so that the L-shaped rod 246 and the clamping block 248 are hidden in the chute 211 again. This not only facilitates the free movement of the bearing on the workbench 210, but also ensures that the feeding mechanism 600 can smoothly push the bearing to the next production step, improving the working efficiency of the grease injection capping machine.

[0082] In a preferred embodiment, the distribution quantity and distribution positions of the pull rope 234, the guide frame 241 and the chute 211 are all the same, and the screw rod 231, the screw sleeve 232 and the workbench 210 are all concentric. In this way, it is ensured that multiple clamping blocks 248 can effectively push the bearing to the center of the workbench 210 and fix it at the central position of the workbench 210 through the way of coordinated movement, improving the production precision of the grease injection capping machine.

[0083] As Figure 2 , Figure 4 and Figure 9 shown, as a preferred embodiment of the present invention, the grease injection mechanism 300 includes a grease injection frame 310, a lifting assembly 320, a rotating assembly 330 and a grease injection gun 340. The grease injection frame 310 is symmetrically fixed at the left and right ends of the machine base 100. The grease injection frame 310 is located on one side of the workbench 210. A lifting assembly 320 is installed on one side of the grease injection frame 310. A rotating assembly 330 is arranged on the other side of the grease injection frame 310. The rotating assembly 330 is connected with the lifting assembly 320. A grease injection gun 340 is fixed on the output end of the rotating assembly 330. The grease injection gun 340 is located directly above the workbench 210.

[0084] In this embodiment, when it is necessary to inject grease into the bearing, the lifting assembly 320 drives the rotating assembly 330 to move vertically on the grease injection frame 310. As the rotating assembly 330 moves vertically, it can drive the connected grease injection gun 340 to synchronously adjust its position, so that the grease injection gun 340 moves to the required working position. The rotating assembly 330 drives the grease injection gun 340 that has moved to the required working position to rotate, so that the positioned grease injection gun 340 rotates around the bearing for one week, and lubricating grease is evenly injected into the bearing in this way, thereby realizing the automatic grease injection of the bearing, effectively completing the lubrication treatment of the bearing, and improving the production efficiency and production quality of the grease injection capping machine.

[0085] As Figure 2 , Figure 4 and Figure 9As shown, as a preferred embodiment of the present invention, the lifting assembly 320 includes a lifting cylinder 321 and a lifting table 322. The lifting cylinder 321 is fixed on the machine base 100, and a lifting table 322 is fixed on the output end of the lifting cylinder 321. The lifting table 322 is vertically slidably arranged on the grease injection frame 310, and a rotating assembly 330 is fixed on one side of the lifting table 322.

[0086] In this embodiment, when grease needs to be injected into the bearing, the lifting cylinder 321 drives the lifting table 322 to move vertically on the grease injection frame 310. The lifting table 322 drives the rotating assembly 330 to move vertically on the grease injection frame 310. As the rotating assembly 330 moves vertically, it can drive the grease gun 340 connected thereto to synchronously adjust the position, so that the grease gun 340 moves to the required working position, facilitating the grease gun 340 to effectively and accurately inject lubricating oil into the bearing, thereby completing the lubrication treatment of the bearing.

[0087] As shown in Figure 2 , Figure 4 and Figure 9 As a preferred embodiment of the present invention, the rotating assembly 330 includes a grease injection motor 331, a transmission member 332, and a rotating shaft 333. The grease injection motor 331 is fixed on one side of the lifting table 322. The rotating shaft 333 is rotatably installed on the lifting table 322 and is concentric with the workbench 210. The output end of the grease injection motor 331 is connected to the rotating shaft 333 through the transmission member 332, and a grease gun 340 is fixed at one end of the rotating shaft 333.

[0088] In this embodiment, the grease injection motor 331 drives the rotating shaft 333 to rotate through the transmission member 332, and the rotating shaft 333 drives the grease gun 340 to rotate, so that the positioned grease gun 340 rotates around the bearing for one week, and in this way, the lubricating grease is evenly injected into the bearing, thereby realizing the automatic grease injection of the bearing, effectively completing the lubrication treatment of the bearing, and improving the production efficiency and production quality of the grease injection capping machine.

[0089] In a preferred embodiment, the transmission member 332 preferably adopts a transmission structure composed of a synchronous belt and a synchronous pulley.

[0090] As shown in Figure 2 , Figure 4 and Figure 10As shown, as a preferred embodiment of the present invention, the gland mechanism 400 includes a gland frame 410, a stacking frame 420, a mounting frame 430, a translation assembly 440 and a gland assembly 450. The gland frames 410 are symmetrically fixed to the left and right ends of the machine base 100. A stacking frame 420 is movably installed on one side of the gland frame 410. A mounting frame 430 is fixed to the other side of the gland frame 410. One end of the translation assembly 440 is fixed to the machine base 100, and the other end of the translation assembly 440 is located below the stacking frame 420 and intermittently cooperates with the workbench 210. The gland assembly 450 is installed on the mounting frame 430 and is located directly above the workbench 210.

[0091] In this embodiment, the stacking frame 420 positions and stacks the bearing caps 700, arranging them vertically and placing them on the translation assembly 440. The translation assembly 440 can intermittently convey the bearing caps 700 to directly below the gland assembly 450 by means of reciprocating movement. The gland assembly 450 can press the bearing caps 700 into the bearing by means of vertical movement, thereby completing the glanding process of the bearing and realizing the encapsulation of the bearing, which not only improves the production efficiency of the grease-injecting glanding machine but also ensures the consistency and stability of the bearing quality.

[0092] In a preferred embodiment, the stacking frame 420 preferably adopts a stacking structure composed of a disc and three support columns. The three support columns are circumferentially and equidistantly fixed on the disc. Through the three circumferentially and equidistantly distributed support columns, not only can multiple vertically arranged bearing caps 700 be aligned, but also the bearing caps 700 can be accurately matched with the translation assembly 440, thereby facilitating the translation assembly 440 to efficiently push the bearing caps 700.

[0093] As Figure 2 、 Figure 4 and Figure 10 As shown, as a preferred embodiment of the present invention, the translation assembly 440 includes a translation cylinder 441, a translation slider 442, a translation guide rail 443, a translation seat 444, a gland opening 445 and an elastic baffle 446. The translation cylinder 441 is fixed to the machine base 100. The output end of the translation cylinder 441 is connected to the translation slider 442. The translation slider 442 is horizontally slidably installed on the translation guide rail 443. The translation guide rail 443 is fixed to the machine base 100. A translation seat 444 is fixed on the translation slider 442. The translation seat 444 is located below the stacking frame 420 and cooperates with it. One end of the translation seat 444 is provided with a gland opening 445 with a diameter larger than the diameter of the bearing cap 700. An elastic baffle 446 is installed inside the gland opening 445, and the elastic baffle 446 intermittently abuts against the bearing cap 700.

[0094] In this embodiment, the translation cylinder 441 drives the translation slider 442 to slide on the translation guide rail, and the translation slider 442 drives the translation seat 444 to reciprocate. When the gland mouth 445 on the translation seat 444 moves below the stacking rack 420, the bearing cover 700 on the stacking rack 420 enters the gland mouth 445, and the elastic baffle 446 supports it and ensures that the bearing cover 700 can be stable on the translation seat 444; when the gland mouth 445 on the translation seat 444 moves directly below the gland assembly 450, at this time, the bearing cover 700 at the gland mouth 445 is directly below the gland assembly 450, and the other end of the translation seat 444 blocks the remaining bearing covers 700 on the stacking rack 420, so that they can be stable on the translation seat 444;

[0095] The gland assembly 450 quickly presses the bearing cover 700 at the gland mouth 445 onto the bearing on the workbench 210 by pressing down. During this process, the squeezed elastic baffle 446 is in a bent state, so that the bearing cover 700 can smoothly pass through the gland mouth 445 and approach the bearing on the workbench 210, thereby completing the encapsulation of the bearing, which not only improves the production efficiency of the grease injection glanding machine, but also ensures the consistency and stability of the bearing quality.

[0096] In a preferred embodiment, the elastic baffle 446 is preferably a fan-shaped sheet structure, the elastic baffle 446 is preferably made of a rubber material with good elasticity, and the elastic force of the elastic baffle 446 is greater than the self-gravity of the bearing cover 700. In this way, in the absence of external force, the elastic baffle 446 can effectively support the bearing cover 700, so that during the movement of the translation seat 444, the bearing cover 700 can be effectively and stably located in the gland mouth 445, thereby ensuring the encapsulation accuracy of the gland assembly 450 for the bearing cover 700.

[0097] As Figure 2 、 Figure 4 and Figure 10 shown, as a preferred embodiment of the present invention, the gland assembly 450 includes a gland cylinder 451 and a pressing head 452. The gland cylinder 451 is fixed on the mounting rack 430, and a pressing head 452 is installed on the output end of the gland cylinder 451. The pressing head 452 is located directly above the workbench 210 and is concentric with it.

[0098] In this embodiment, the gland cylinder 451 drives the gland head 452 to move downward. By moving downward, the gland head 452 can quickly press-fit the bearing cover 700 located in the gland port 445 onto the bearing on the workbench 210. During this process, the gland head 452 and the bearing cover 700 cooperate to squeeze the elastic baffle 446, causing the elastic baffle 446 to be in a bent state, ensuring that the bearing cover 700 can smoothly pass through the gland port 445 and approach the bearing on the workbench 210, thereby completing the encapsulation of the bearing. This not only improves the production efficiency of the grease injection glanding machine but also ensures the consistency and stability of the bearing quality.

[0099] As Figures 1 to 10 shown, as a preferred embodiment of the present invention, the feeding mechanism 600 includes a Y-axis cylinder, a Y-axis guide rail 610, an X-axis cylinder, an X-axis guide rail 620, a feeding slider 630, a mounting post 640, and a feeding plate 650. The Y-axis cylinder and the Y-axis guide rail 610 are both fixed on the machine base 100. The X-axis guide rail 620 is horizontally slidably mounted on the Y-axis guide rail 610. The output end of the Y-axis cylinder is connected to the X-axis guide rail 620. An X-axis cylinder is mounted on the X-axis guide rail 620. The output end of the X-axis cylinder is connected to the feeding slider 630 slidably mounted on the X-axis guide rail 620. The mounting post 640 is fixed on the feeding slider 630. The feeding plate 650 is horizontally distributed on the mounting post 640. The bottom of the feeding plate 650 is higher than the top of the workbench 210.

[0100] In this embodiment, the Y-axis cylinder drives the X-axis guide rail 620 to move toward or away from the workbench 210. As the X-axis guide rail 620 approaches or moves away from the workbench 210, it can drive the feeding slider 630 to approach or move away from the workbench 210. The feeding slider 630 drives the mounting post 640 and the feeding plate 650 to approach or move away from the workbench 210. When the feeding plate 650 moves away from the workbench 210, it is convenient for the grease injection mechanism 300 and the glanding mechanism 400 to inject grease and gland the bearing, thereby completing the lubrication and encapsulation of the bearing.

[0101] When the feeding plate 650 approaches the workbench 210, the X-axis cylinder drives the feeding slider 630 to slide on the X-axis guide rail 620. The feeding slider 630 drives the mounting post 640 and the feeding plate 650 to move along the layout track of the X-axis guide rail 620. By moving in this way, the feeding plate 650 can not only push the bearing located under the grease injection mechanism 300 to the lower part of the gland pressing mechanism 400, facilitating the gland pressing mechanism 400 to package the bearing after grease injection, but also push the bearing under the gland pressing mechanism 400 into the spiral turning chute 500, enabling the bearing that has completed single-sided grease injection and gland pressing to be reversed, facilitating the grease injection mechanism 300 and the gland pressing mechanism 400 to perform grease injection and gland pressing on the other side of the bearing, thereby realizing the continuous automatic operation of the grease injection and gland pressing machine, and significantly improving the production efficiency and production quality of the grease injection and gland pressing machine.

[0102] The working principle of the present invention is:

[0103] In the initial state, both the L-shaped rod 246 and the clamping block 248 are hidden in the chute 211. The positioning motor drives the screw rod 231 to rotate. The screw rod 231 can drive the nut sleeve 232 to move vertically by cooperating with the guide post 233. The nut sleeve 232 pulls the pull rope 234, and the pull rope 234 pulls the connecting rod 244. The connecting rod 244 drives the pulley 243 to move in the guide groove 242. The pulley 243 can drive one end of the connecting rod 244 to move up and translate on the guide frame 241 by cooperating with the guide groove 242. As the connecting rod 244 moves upward, it can cause the L-shaped rod 246 to rotate 90 degrees on the clamping slider 247, and the L-shaped rod 246 drives the clamping block 248 to rotate 90 degrees, making the clamping block 248 parallel to the outer wall of the bearing. As the connecting rod 244 translates, it can drive the clamping block 248 that has rotated 90 degrees through the L-shaped rod 246 to move. At the same time, the connecting rod 244 squeezes the spring 245, putting it in a state of storing energy. Multiple clamping blocks 248 work together and can push the bearing on the workbench 210 to the center of the workbench 210 by moving closer to each other, and clamp and fix the bearing located at the center of the workbench 210. When the bearing is completed with greasing or capping, the positioning motor drives the screw rod 231 to rotate in the reverse direction. The screw rod 231 drives the nut sleeve 232 to move in the reverse direction. The nut sleeve 232 releases the pull rope 234. At this time, the spring 245 drives the connecting rod 244 to translate and move downward in the reverse direction through its own elastic force. As the connecting rod 244 translates in the reverse direction, it can drive the clamping block 248 to move away from the bearing, thus releasing the clamping and fixing of the bearing and making the bearing in a free state on the workbench 210. As the connecting rod 244 moves downward, the connecting rod 244 can drive the L-shaped rod 246 and the clamping block 248 to rotate 90 degrees in the reverse direction, making the L-shaped rod 246 and the clamping block 248 hidden in the chute 211 again. This not only facilitates the free movement of the bearing on the workbench 210 but also ensures that the feeding mechanism 600 can smoothly push the bearing to the next production step;

[0104] When greasing the bearing is required, the lifting cylinder 321 drives the lifting table 322 to move vertically on the greasing frame 310. The lifting table 322 drives the rotating assembly 330 to move vertically on the greasing frame 310. As the rotating assembly 330 moves vertically, it can drive the grease gun 340 connected to it to synchronously adjust the position, so that the grease gun 340 moves to the required working position, facilitating the grease gun 340 to effectively and accurately inject lubricating oil into the bearing. The greasing motor 331 drives the rotating shaft 333 to rotate through the transmission member 332. The rotating shaft 333 drives the grease gun 340 to rotate, making the positioned grease gun 340 rotate around the bearing for one week, and in this way, evenly inject the grease into the bearing, thus realizing the automatic greasing of the bearing;

[0105] The stacking rack 420 positions and stacks the bearing caps 700 in a vertical arrangement and places them on the translation assembly 440. The translation cylinder 441 drives the translation slider 442 to slide on the translation guide rail. The translation slider 442 drives the translation seat 444 to move reciprocally. When the gland mouth 445 on the translation seat 444 moves below the stacking rack 420, the bearing caps 700 on the stacking rack 420 enter the gland mouth 445. The elastic baffle 446 supports them and ensures that the bearing caps 700 can be stable on the translation seat 444. When the gland mouth 445 on the translation seat 444 moves directly below the gland assembly 450, at this time, the bearing caps 700 at the gland mouth 445 are directly below the gland assembly 450. The other end of the translation seat 444 blocks the remaining bearing caps 700 on the stacking rack 420, making them stable on the translation seat 444. The gland cylinder 451 drives the pressing head 452 to move downward. The pressing head 452 can quickly press-fit the bearing caps 700 located in the gland mouth 445 into the bearings on the workbench 210 by moving downward. During this process, the pressing head 452 cooperates with the bearing caps 700 to squeeze the elastic baffle 446, making the elastic baffle 446 in a bent state, ensuring that the bearing caps 700 can smoothly pass through the gland mouth 445 and approach the bearings on the workbench 210, thus completing the encapsulation of the bearings.

[0106] The Y-axis cylinder drives the X-axis guide rail 620 to move towards or away from the workbench 210. As the X-axis guide rail 620 approaches or moves away from the workbench 210, it can drive the feeding slider 630 to approach or move away from the workbench 210. The feeding slider 630 drives the mounting post 640 and the feeding plate 650 to approach or move away from the workbench 210. When the feeding plate 650 moves away from the workbench 210, it is convenient for the grease injection mechanism 300 and the glanding mechanism 400 to inject grease and gland the bearings, thus completing the lubrication and encapsulation of the bearings. When the feeding plate 650 approaches the workbench 210, the X-axis cylinder drives the feeding slider 630 to slide on the X-axis guide rail 620. The feeding slider 630 drives the mounting post 640 and the feeding plate 650 to move along the layout track of the X-axis guide rail 620. By moving in this way, the feeding plate 650 can not only push the bearings located below the grease injection mechanism 300 to below the glanding mechanism 400, facilitating the glanding mechanism 400 to encapsulate the bearings after grease injection, but also push the bearings below the glanding mechanism 400 into the spiral flipping chute 500, enabling the bearings that have completed single-sided grease injection and glanding to be reversed, facilitating the grease injection mechanism 300 and the glanding mechanism 400 to inject grease and gland the other side of the bearings, and thus realizing the automatic lubrication and encapsulation of both sides of the bearings.

[0107] The above is the working principle of this automatic bearing grease injection and glanding machine.

[0108] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
