[0069] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0070] like Figures 1 to 10As shown, an automatic bearing grease injection and capping machine provided as an embodiment of the present invention includes a machine base 100, the left and right ends of the machine base 100 have different heights, and the left end of the machine base 100 is lower than the right end, and the left and right ends of the machine base 100 are provided with a grease injection mechanism 300 and a capping mechanism 400, the grease injection mechanism 300 is located on one side of the capping mechanism 400, and the grease injection mechanism 300 located on the left end of the machine base 100 and the capping mechanism 400 located on the right end of the machine base 100 are close to each other, the grease injection mechanism 300 is used to grease the bearing, and the capping mechanism 400 is used to press the bearing cover 700 onto the bearing, and also includes:

[0071] The spiral flip slide 500 is tilted and arranged in the middle of the base 100. The highest input end of the spiral flip slide 500 cooperates with the capping mechanism 400 located on the right end of the base 100, and the lowest output end of the spiral flip slide 500 cooperates with the grease injection mechanism 300 located on the left end of the base 100. A spiral groove 510 is provided inside the spiral flip slide 500. The spiral flip slide 500 can adjust the weight of the objects entering the spiral groove by means of a cleverly designed tilt angle and the use of the gravity of the bearing itself. The bearing in 510 is efficiently turned over, thereby realizing the reversal of the bearing, which not only simplifies the operation process, but also enables the grease injection mechanism 300 and the capping mechanism 400 located at both ends of the machine base 100 to more conveniently complete the lubrication and sealing of the two sides of the bearing, thereby greatly improving the overall automation level of the grease injection and capping machine. Compared with the traditional turning device used alone, the integrated spiral turning slide 500 has the advantages of less space occupation, faster turning speed and higher cost-effectiveness, which significantly improves the practicality and work efficiency of the bearing grease injection and capping machine.

[0072] The feeding mechanism 600 is provided with two groups, and the two groups of the feeding mechanism 600 are respectively arranged on one side of the left and right ends of the machine base 100. The feeding mechanism 600 can not only push the bearing that has been greased by the grease injection mechanism 300 to the capping mechanism 400 by moving along the X-axis and the Y-axis, so as to facilitate the capping process of the capping mechanism 400, but also push the bearing that has been capped by the capping mechanism 400 into the spiral turning slide 500, so as to facilitate the spiral turning slide 500 to turn and reverse it, thereby facilitating the grease injection mechanism 300 and the capping mechanism 400 to lubricate and seal the other side of the bearing, thereby realizing the full automation and continuity of the grease injection and capping machine;

[0073] The positioning mechanism 200 includes a workbench 210, a slide groove 211, a connecting groove 212, a shock-absorbing base 220, a control component 230 and a clamping component 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 capping mechanism 400 and is concentric with the two. The workbench 210 is circumferentially distributed with slide grooves 211, and the workbench 210 is 0 are provided with connecting grooves 212 on both sides, a connecting plate 800 is provided between two workbenches 210 at the same height of the machine base 100, and the two ends of the connecting plate 800 are respectively locked in the connecting grooves 212 on the two workbenches 210 by screws, and a control component 230 is provided at the bottom of the workbench 210, one end of the control component 230 is installed on the machine base 100, and the other end of the control component 230 is connected to the clamping components 240 distributed circumferentially 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 frame 241 is equidistantly distributed at the bottom of the workbench 210 according to the distribution track of the slide groove 211 and is fixedly connected to the shock-absorbing base 220. The guide frame 241 is provided with a guide groove 242 with different heights at both ends, and a pulley 243 is slidably installed in the guide groove 242. 3. The pulley 243 is connected to one end of a connecting rod 244, and the other end of the connecting rod 244 is connected to one end of an L-shaped rod 246 rotatably mounted on a clamping slider 247. The clamping slider 247 is slidably mounted in the slide groove 211, and a clamping block 248 is fixed to the other end of the L-shaped rod 246. 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 slide groove 211. The control component 230 pulls the connecting rod 244, and 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 upward 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, so that the clamping block 248 is parallel to the outer wall of the bearing.

[0076] As the connecting rod 244 translates, it can drive the clamping block 248 to rotate 90 degrees to move through the L-shaped rod 246. At the same time, the connecting rod 244 squeezes the spring 245 to put it in a force storage state. Multiple clamping blocks 248 work together and move closer to each other. The bearing on the workbench 210 can be pushed to the center of the workbench 210, and the bearing located at the center of the workbench 210 can be clamped and fixed. This not only simplifies the operating process, but also greatly improves the efficiency and accuracy of the grease injection mechanism 300 and the capping mechanism 400 in lubricating and sealing the bearings, thereby improving the working performance of the entire grease injection and capping 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 without causing additional damage to the outer wall of the bearing, thereby ensuring the aesthetics of the bearing.

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

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

[0080] When the bearing is greased or capped, the positioning motor drives the screw 231 to rotate in the opposite direction, and the screw 231 drives the screw sleeve 232 to move in the opposite direction, and the screw sleeve 232 releases the pull rope 234. At this time, the spring 245 drives the connecting rod 244 to move in the opposite direction and downward through its own elastic force. As the connecting rod 244 moves in the opposite direction, it can drive the clamping block 248 to move away from the bearing, thereby releasing the clamping and fixing of the bearing, so that the bearing is 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 opposite direction, so that the L-shaped rod 246 and the clamping block 248 are hidden in the slide groove 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, thereby improving the working efficiency of the grease injection and capping machine.

[0082] In a preferred embodiment, the distribution quantity and distribution position of the pull rope 234, the guide frame 241 and the slide groove 211 are consistent, and the screw 231, the screw sleeve 232 and the workbench 210 are concentric, so as to ensure that the multiple clamping blocks 248 can effectively push the bearing to the center of the workbench 210 through coordinated movement, and fix it in the center position of the workbench 210, thereby improving the production accuracy of the grease injection and capping machine.

The rotating assembly 330 is connected to the lifting assembly 320. A grease gun 340 is fixed on the output end of the rotating assembly 330. The grease gun 340 is located directly above the workbench 210.

[0084] In this embodiment, when the bearing needs to be greased, 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 grease gun 340 connected thereto to synchronously adjust its position, so that the grease gun 340 moves to the required workstation. The rotating assembly 330 drives the grease gun 340 moved to the required workstation to rotate, so that the positioned grease gun 340 rotates around the bearing for one circle, and in this way, grease is evenly added to the bearing, thereby realizing automatic grease injection of the bearing, effectively completing the lubrication process of the bearing, and improving the production efficiency and production quality of the grease injection and capping machine.

As the rotating assembly 330 moves vertically, it can drive the grease gun 340 connected thereto to synchronously adjust its position, so that the grease gun 340 moves to the required work station, making it convenient for the grease gun 340 to effectively and accurately add lubricating oil into the bearing, thereby completing the lubrication process of the bearing.

The three support columns are evenly distributed circumferentially, which can not only ensure that the multiple bearing caps 700 arranged vertically can be aligned, but also ensure that 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] like Figure 2 , Figure 4 and Fig.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 pressure cover opening 445 and an elastic baffle 446, the translation cylinder 441 is fixed on 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 on 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 therewith, one end of the translation seat 444 is provided with a pressure cover opening 445 whose diameter is larger than that of the bearing cover 700, the inner side of the pressure cover opening 445 is installed with an elastic baffle 446, and the elastic baffle 446 intermittently interferes with the bearing cover 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 move back and forth. When the pressure cover opening 445 on the translation seat 444 moves to the bottom of the stacking frame 420, the bearing cover 700 on the stacking frame 420 enters the pressure cover opening 445, and the elastic baffle 446 supports it and ensures that the bearing cover 700 can be stably on the translation seat 444; when the pressure cover opening 445 on the translation seat 444 moves to the bottom of the pressure cover assembly 450, the bearing cover 700 at the pressure cover opening 445 is located directly below the pressure cover assembly 450, and the other end of the translation seat 444 blocks the remaining bearing cover 700 on the stacking frame 420, so that it can be stable on the translation seat 444;

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

[0096] In a preferred embodiment, the elastic baffle 446 preferably adopts a fan-shaped sheet structure, and 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 gravity of the bearing cover 700 itself, so that in the absence of external force, the elastic baffle 446 can effectively support the bearing cover 700, so that when the translation seat 444 moves, the bearing cover 700 can be effectively and stably located in the pressure cover opening 445, thereby ensuring the packaging accuracy of the pressure cover assembly 450 for the bearing cover 700.

[0097] like Figure 2 , Figure 4 and Fig.10 As shown, as a preferred embodiment of the present invention, the capping assembly 450 includes a capping cylinder 451 and a pressing head 452, the capping cylinder 451 is fixed on the mounting frame 430, the pressing head 452 is installed on the output end of the capping cylinder 451, and the pressing head 452 is located directly above the workbench 210 and concentric therewith.

[0098] In this embodiment, the pressing cylinder 451 drives the pressing head 452 to move downward, and the pressing head 452 can quickly press the bearing cover 700 located in the pressing cover opening 445 into the bearing on the workbench 210 by moving downward. During this process, the pressing head 452 cooperates with the bearing cover 700 to squeeze the elastic baffle 446, so that the elastic baffle 446 is in a bent state, ensuring that the bearing cover 700 can smoothly pass through the pressing cover opening 445 and approach the bearing on the workbench 210, thereby completing the packaging of the bearing, which not only improves the production efficiency of the grease injection and capping machine, but also ensures the consistency and stability of the bearing quality.

[0099] like Figures 1 to 10 As 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 column 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, the 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 feeding slider 630 is fixed with a mounting column 640, the mounting column 640 is horizontally distributed with a feeding plate 650, and 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 moves toward or away from the workbench 210, it can drive the feeding slider 630 to move toward or away from the workbench 210. The feeding slider 630 drives the mounting column 640 and the feeding plate 650 to move toward or away from the workbench 210. When the feeding plate 650 moves away from the workbench 210, the grease injection mechanism 300 and the capping mechanism 400 can be conveniently used to inject grease and cap the bearing, thereby completing the lubrication and packaging 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, and the feeding slider 630 drives the mounting column 640 and the feeding plate 650 to move along the layout trajectory of the X-axis guide rail 620. The feeding plate 650 can not only push the bearing under the grease injection mechanism 300 to the bottom of the capping mechanism 400 by moving, so as to facilitate the capping mechanism 400 to package the greased bearing, but also push the bearing under the capping mechanism 400 into the spiral flip slide 500, so that the bearing that has completed single-side grease injection and capping can be reversed, so as to facilitate the grease injection mechanism 300 and the capping mechanism 400 to grease and cap the other side of the bearing, thereby realizing the continuous automatic operation of the grease injection and capping machine, and significantly improving the production efficiency and production quality of the grease injection and capping machine.

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

[0103] In the initial state, the L-shaped rod 246 and the clamping block 248 are hidden in the slide groove 211, the positioning motor drives the screw 231 to rotate, the screw 231 can drive the screw sleeve 232 to move vertically by cooperating with the guide column 233, the screw sleeve 232 pulls the pull rope 234, 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 in the guide frame 24 1 moves upward and in translation. 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, so that the clamping block 248 is parallel to the outer wall of the bearing; as the connecting rod 244 moves in translation, the clamping block 248 that rotates 90 degrees can be driven to move by the L-shaped rod 246. At the same time, the connecting rod 244 squeezes the spring 245 to put it in a power storage state. Multiple clamping blocks 248 work together and are pressed against each other. The bearing on the workbench 210 can be pushed to the center of the workbench 210 by a close movement method, and the bearing located at the center of the workbench 210 can be clamped and fixed. When the bearing is greased or capped, the positioning motor drives the screw rod 231 to rotate in the opposite direction, and the screw rod 231 drives the screw sleeve 232 to move in the opposite direction. The screw sleeve 232 releases the pull rope 234. At this time, the spring 245 drives the connecting rod 244 to move in the opposite direction and move downward through its own elastic force. As the connecting rod 244 moves in the opposite direction, it can drive the clamping block 2 48 moves in a direction away from the bearing, thereby releasing the clamping and fixing of the bearing, so that the bearing is 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 opposite direction, so that the L-shaped rod 246 and the clamping block 248 are hidden in the slide groove 211 again, which 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 the bearing needs to be greased, the lifting cylinder 321 drives the lifting platform 322 to move vertically on the grease injection frame 310, and the lifting platform 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 injection gun 340 connected thereto to adjust its position synchronously, so that the grease injection gun 340 moves to the required position, so that the grease injection gun 340 can effectively and accurately inject lubricating oil into the bearing; 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 injection gun 340 to rotate, so that the positioned grease injection gun 340 rotates around the bearing for one circle, and in this way, the grease is evenly injected into the bearing, thereby realizing automatic grease injection of the bearing;

[0105] The stacking rack 420 positions and stacks the bearing caps 700 so that they are arranged vertically and placed on the translation assembly 440. 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 move back and forth. When the pressure cover opening 445 on the translation seat 444 moves to the bottom of the stacking rack 420, the bearing cap 700 on the stacking rack 420 enters the pressure cover opening 445, and the elastic baffle 446 supports it and ensures that the bearing cap 700 can be stable on the translation seat 444; when the pressure cover opening 445 on the translation seat 444 moves to the bottom of the pressure cover assembly 450, the bearing cap 700 at the pressure cover opening 445 is located in the pressure cover assembly. The other end of the translation seat 444 blocks the remaining bearing cap 700 on the stacking frame 420, so that it can be stabilized on the translation seat 444; the capping cylinder 451 drives the pressing head 452 to move downward, and the pressing head 452 can quickly press the bearing cap 700 located in the capping opening 445 into the bearing on the workbench 210 by moving downward. In this process, the pressing head 452 cooperates with the bearing cap 700 to squeeze the elastic baffle 446, so that the elastic baffle 446 is in a bent state, ensuring that the bearing cap 700 can smoothly pass through the capping opening 445 and approach the bearing on the workbench 210, thereby completing the packaging of the bearing;

[0106] 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 column 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, the grease injection mechanism 300 and the capping mechanism 400 can be conveniently used to inject grease and cap the bearing, thereby completing the lubrication and packaging of the bearing. 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 column 640 and the feeding plate 650 to move along the layout track of the X-axis guide rail 620. The feeding plate 650 can not only push the bearing located below the grease injection mechanism 300 to below the capping mechanism 400 by moving, so that the capping mechanism 400 can package the greased bearing, but also push the bearing below the capping mechanism 400 into the spiral flip slide 500, so that the bearing that has completed grease injection and capping on one side can be reversed, so that the grease injection mechanism 300 and the capping mechanism 400 can grease and cap the other side of the bearing, thereby realizing automatic lubrication and packaging of both sides of the bearing.

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

[0108] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
