All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
As shown in fig. 1 to 9, the invention provides a polishing device for producing an automobile bearing, which comprises a workbench 100, wherein one side of the top of the workbench 100 is slidably connected with a movable plate 200, an electric clamp 300 is adjustably arranged in the middle of the movable plate 200, and a U-shaped frame 400 is fixedly connected with the other side of the workbench 100, and the polishing device further comprises:
The multi-surface polishing mechanism 500, wherein the multi-surface polishing mechanism 500 is positioned at the inner side of the U-shaped frame 400;
The dredging mechanism 600 is connected with the multi-surface polishing mechanism 500;
Wherein, the multi-surface polishing mechanism 500 comprises a fixed plate 550 fixedly connected to the inner side of the U-shaped frame 400, two sides of the fixed plate 550 are respectively and slidably connected with an inner ring polishing block 570 and an outer ring polishing block 5180 through a long sliding chute 5100, the middle part of the fixed plate 550 is slidably connected with a telescopic block 540 through a middle groove 590, and the end part of the telescopic block 540 is fixedly connected with a pair of side polishing blocks 560;
By adopting the scheme, the movable plate 200 is externally connected with an electric push rod for driving, and the turntable end part of the electric clamp 300 is driven to rotate by a driving motor and is used for driving the bearing to rotate at a high speed so as to facilitate grinding operation. The moving plate 200 on the table 100 cooperates with the electric jig 300 to ensure that the bearing is firmly and precisely clamped. The moving plate 200 is connected to the U-shaped frame 400 by sliding so that the entire polishing mechanism can be stably operated. The multi-faceted grinding mechanism 500 is located inside the U-shaped frame 400 and precisely mates with the inner and outer ring grinding blocks 570 and 5180 via the fixing plate 550. The long runner 5100 of the retainer plate 550 enables both the inner ring grinding blocks 570 and the outer ring grinding blocks 5180 to slide in an axial direction to accommodate bearings of different sizes. The telescoping block 540 is connected to the fixed plate 550 through the middle groove 590 so that the side grinding block 560 can precisely contact the edge of the bearing, thereby completing the full grinding of the inner and outer rings and the end side walls of the bearing. In addition, the dredging mechanism 600 is connected with the multi-surface polishing mechanism 500, so that generated metal particles and impurities are ensured to be removed in time in the polishing process, and the polishing precision is maintained. Through the cooperation of each mechanism, the whole device can realize high-efficient, even bearing polishing.
As shown in fig. 2 to 6 and 9, the multi-surface polishing mechanism 500 further includes a push plate 520 fixedly connected to an output end of a cylinder 510 of the cylinder 510 at the inner side of the middle of the U-shaped frame 400, oblique pressing plates 530 symmetrically fixedly connected to two sides of the push plate 520, T-shaped sliding grooves 5120 formed at inner sides of the oblique pressing plates 530, outer walls of the oblique pressing plates 530 slidably sleeved on the fixing plates 550, exhaust grooves 5170 formed through the fixing plates 550, T-shaped blocks 5130 slidably connected to the pair of oblique pressing plates 530 through the T-shaped sliding grooves 5120, end portions of the pair of T-shaped blocks 5130 fixedly connected to corners of the inner ring grinding blocks 570 and the outer ring grinding blocks 5180, movable grooves 5110 formed at one sides of the inner ring grinding blocks 570 and the outer ring grinding blocks 5180 close to the telescopic blocks 540, and first shaft grooves 5140 formed at two sides of the inner wall of the movable grooves 5110.
As shown in fig. 6 and 7, a U-shaped through groove 5150 is formed in the middle of the telescopic block 540, a pair of second shaft grooves 5160 are formed on two sides of the inner wall of the U-shaped through groove 5150, a pair of angle guiding grinding blocks 580 are rotatably connected to the telescopic block 540 through the U-shaped through groove 5150 and the second shaft grooves 5160, and the end parts of the pair of angle guiding grinding blocks 580 are movably connected to the first shaft grooves 5140 through rotating shafts respectively.
With the above-described arrangement, first branch pipe 640 and second branch pipe 650 are each provided as a hose, and do not hinder movement of push plate 520. Prior to sanding, cylinder 510 is activated to push plate 520 in the direction of the bearing. The inclined pressing plates 530 fixedly connected to the two sides of the push plate 520 move along with the push plate 520 and slide in cooperation with the T-shaped blocks 5130 through the T-shaped sliding grooves 5120, so that the inner ring grinding blocks 570 and the outer ring grinding blocks 5180 connected to the end parts of the T-shaped blocks 5130 are synchronously close to each other and centered, and accurate grinding of the inner ring and the outer ring of the bearing by the grinding blocks is ensured. In addition, during pushing of push plate 520, telescoping block 540 also moves toward the bearing until side blocks 560 at its ends come into close contact with the edge side walls of the bearing. At this time, the inner ring grinding block 570 and the outer ring grinding block 5180 are respectively contacted with the surfaces of the inner ring and the outer ring of the bearing, and are integrally formed into a U-shaped shape and firmly clamped on the outer wall of the bearing. When the bearing starts to rotate at a high speed, the polishing actions of the inner ring, the outer ring and the side wall of the end part are synchronously performed, so that the bearing is polished comprehensively. As the telescoping block 540 moves toward the bearing, the inner ring grinding block 570 and the outer ring grinding block 5180 approach each other centrally and the articulating chamfer grinding blocks 580 on both sides come into play. The chamfer block 580 can slide within the first shaft groove 5140 and the second shaft groove 5160 to accommodate bearings of different thicknesses by varying the included angle. The device can polish the inner ring, the outer ring, the guide angle and the end side wall of the bearing simultaneously, so that the traditional operation of replacing the grinding head for multiple times is greatly simplified, and the polishing speed and the polishing efficiency are improved. When the bearing is thicker, the included angle of the lead angle grinding block 580 is relatively enlarged, the lead angle becomes more gentle, and when the bearing is thinner, the included angle of the lead angle grinding block 580 is tightened to form a sharper angle so as to accurately grind the edge of the bearing. The self-adaptive adjustment mechanism of the lead angle grinding block 580 can effectively adjust the angle according to the actual thickness of the bearing, and ensure that the bearing can be matched with either a thick bearing or a thin bearing.
As shown in fig. 6 to 9, the dredging mechanism 600 includes an air bag 610 fixedly connected to the inner side wall of the U-shaped frame 400, one side of the air bag 610 is provided with a pair of unidirectional air inlets 620, the other side of the air bag 610 is fixedly connected with an air outlet pipe 630 through a unidirectional valve, the outer wall of the air outlet pipe 630 is fixedly connected to the push plate 520, one end of the air outlet pipe 630 is fixedly connected with a first branch pipe 640, the other end of the air outlet pipe 630 is fixedly connected with a second branch pipe 650, the end of the first branch pipe 640 is fixedly penetrated through the side wall of the telescopic block 540, the first branch pipe 640 is communicated with the U-shaped through groove 5150, the end of the second branch pipe 650 is fixedly connected to the side wall of the lower end of the fixed plate 550, the middle part of the lower inclined pressure plate 530 is provided with a side air outlet 660, and the bottom of the inclined pressure plate 530 is provided with a lower air outlet 670.
By adopting the scheme, part of powdery metal particles are necessarily generated in the polishing process and fall into each groove in the device. In order to ensure long-term stable operation of the polishing apparatus, timely removal of these impurities is critical. After finishing the polishing, the actuating cylinder 510 is quickly retracted, and the air bag 610 is instantaneously compressed to push the air therein to be discharged, and is branched to the first branched pipe 640 and the second branched pipe 650 through the exhaust pipe 630. After entering the first branch pipe 640, the air flow impacts the U-shaped through groove 5150 at a high speed, and the metal particles in the groove are blown out. The air flow in the second branch pipe 650 enters the T-shaped chute 5120 through the side air vent 660 on the outer wall of the inclined pressing plate 530, thereby effectively avoiding the accumulation of metal particles in the inclined pressing plate 530 and ensuring the smooth sliding of the T-shaped chute 5120. Through the cooperation of first branch pipe 640 and second branch pipe 650, can in time clear away the hole inslot wall that the device downside is easy to block up after polishing at every turn, prevent impurity and store up to keep the steady operation of equipment, ensure stability and the high efficiency in the polishing process at every turn. In addition, the lubricant can be communicated with the pipe orifice, and is sprayed into the groove for lubrication through air pressure, and even if part of scraps in the groove are not blown away, the connecting part can be extruded along the lubricant, so that the movement of the structure is not hindered.
The working principle and the using flow of the invention are as follows:
Firstly, the vertical side of the bearing is abutted against the electric clamp 300, so that the inner ring and the outer ring of the bearing are firmly clamped, then the moving plate 200 is pushed to move towards the direction of the U-shaped frame 400 by an external electric push rod, so that the side wall of the bearing passes through and is sleeved on the outer side of the inner ring grinding block 570, and at the moment, the inner ring grinding block 570 and the outer ring grinding block 5180 are respectively positioned on the inner side and the outer side of the bearing. Then, the cylinder 510 is started to move the push plate 520 towards the direction of the bearing, and the inclined pressing plates 530 fixedly connected to the two sides of the push plate 520 move along with the push plate 520 and squeeze the T-shaped blocks 5130 to slide through the T-shaped sliding grooves 5120, so that the inner ring grinding blocks 570 and the outer ring grinding blocks 5180 connected with the end parts of the T-shaped blocks 5130 are synchronously centered and close. Meanwhile, under the pushing of the push plate 520, the telescopic block 540 moves towards the bearing until the side grinding block 560 at the end part of the telescopic block abuts against the edge side wall of the bearing, at this time, the inner ring grinding block 570 and the outer ring grinding block 5180 also abut against the inner ring surface and the outer ring surface of the bearing respectively, the U-shaped clamping is integrally formed on the outer wall of the bearing, and when the bearing rotates at a high speed, the inner ring, the outer ring and the end side wall of the bearing are polished simultaneously. In the bearing positioning process, the electric clamp 300 and the moving plate 200 move cooperatively through the intelligent control system, so that the inner ring grinding block 570 and the outer ring grinding block 5180 are smoothly centered;
Secondly, since the telescopic block 540 moves towards the bearing, the inner ring grinding block 570 and the outer ring grinding block 5180 are close to each other in the middle, so that the pair of angle guiding grinding blocks 580 movably connected at two sides respectively squeeze and slide in the first shaft groove 5140 and the second shaft groove 5160, the included angle is reduced, and the edge angle guiding of the bearing can be ground through the angle guiding grinding blocks 580. And according to the width size of the bearing, the rotating angles of the guide angle grinding blocks 580 are different, when the bearing is thicker, the included angle of the guide angle grinding blocks 580 is relatively enlarged, the guide angle is more gentle, when the bearing is thinner, the included angle adduction of a pair of guide angle grinding blocks 580 is smaller, and the bearing edge at the moment is more attached, so that the bearing polishing machine can effectively adapt to bearing polishing with different thicknesses through the angle change of the automatically-adjusted guide angle grinding blocks 580. And the polishing direction is matched, the device can polish the guide angle, the inner ring, the outer ring and the end side wall of the bearing simultaneously, so that the polishing process is simplified, and the polishing speed is improved. After one side is polished, the bearing is taken down, turned over and polished once again, so that the whole bearing can be polished in all directions, and the polishing of each surface is not required to be switched to different grinding heads;
Again, during the polishing process, some of the powder metal particles fly away and fall into the grooves inside the device, after polishing, the starting cylinder 510 is retracted at high speed, and the air bag 610 is instantaneously extruded by the larger extrusion force, so that the air in the air bag 610 is pressurized to push out of the exhaust pipe 630, and then enters the first branch pipe 640 and the second branch pipe 650 respectively. The air flow entering the first branch pipe 640 enters the U-shaped through groove 5150 to impact at a high speed, as shown by the tip of fig. 7, metal particles possibly falling into the inner corners are blown out along the notch, and the air can be dispersed and guided into other hole grooves to remove impurities by the long sliding groove 5100 communicated with the fixing plate 550. The air flow entering the second branch 650 passes through the long sliding groove 5100 at the bottom of the fixing plate 550 through the air exhaust groove 5170, and is exhausted outside the device, and the direction of the air flow is shown as an arrow direction in fig. 9. At this time, the inclined pressing plate 530 dynamically moves in the fixing plate 550, so that air flow can enter the T-shaped chute 5120 through the side air vent 660 on the outer wall of the inclined pressing plate 530 to blow, and the arrangement of the lower air vent 670 effectively avoids the accumulation of metal particles and impurities in the inclined pressing plate 530 below, which affects the sliding effect of the T-shaped chute 5120. In this way, the first branch pipe 640 and the second branch pipe 650 can impact the high-speed air flow on the device to easily store the impurity, so that the impurity can be automatically cleaned in time after polishing each time, and the operation of the device is prevented. The lubricant can be connected to the two pipe orifices and sprayed into the groove along with the airflow, so that the lubrication degree is increased;
Finally, each time the push plate 520 moves toward the bearing direction, the compressed air bag 610 may be driven to stretch and reset, and the air is supplemented through the unidirectional air inlet 620, and the unidirectional valve at the end of the exhaust pipe 630 cannot absorb the air into the air bag 610, and only the air can be discharged outwards, so that the stable unidirectional air inlet and exhaust process of the air bag 610 is maintained.
