Technical Field

[0001] The invention relates to the technical field of bearing processing, and in particular to a high-efficiency bearing processing device. Background Art

[0002] Bearings are components that fix and reduce the load friction coefficient during mechanical transmission. When other parts move relative to each other on the shaft, they are used to reduce the friction coefficient during power transmission and keep the center position of the shaft fixed.

[0003] When processing bearings, the blank material needs to be turned into inner sleeves, outer sleeves, and bead blanks, heat treated, ground into finished products (grinding processes include internal grinding, external grinding, and centerless grinding), and assembled into finished products. In the existing technology, grinding is a type of surface modification technology, the main purpose of which is to obtain a specific surface roughness. Grinding the bearing can remove burrs or chamfers on the bearing surface, which can improve the quality of the bearing.

Not only that, it is also necessary to manually position the bearing to confirm that the installation position of the bearing is appropriate and can cooperate with the grinding knife. After the bearing grinding and processing is completed, the bearing needs to be removed. Therefore, the existing grinding and processing device has a long processing time and low production efficiency. In addition, the metal scraps generated when grinding the bearing are small and numerous. Not only is it difficult to collect and reuse the scraps, which is a serious waste of materials, but it also needs to be cleaned regularly, affecting production efficiency. Summary of the invention

[0006] A second object of the present invention is to provide a processing method.

[0007] To achieve one of the above-mentioned purposes, the present invention adopts the following technical scheme: a high-efficiency bearing processing device, which includes: a positioning and clamping converter; an external control mechanism, one end of which can be rotatably installed on the side end of the positioning and clamping converter, and the external control mechanism is evenly distributed on the side end of the positioning and clamping converter around the center position of the positioning and clamping converter, and the external control mechanism has: a working chamber, the working chamber transversely passes through the external control mechanism, and the diameter of the working chamber is larger than the outer circle of the bearing; a positioning and clamping part, the positioning and clamping part is arranged at the other end of the external control mechanism, and the positioning and clamping part includes: a connecting piece, the connecting piece is movably connected to the external control mechanism; a limiting piece, the limiting piece is connected to one end of the connecting piece, and the limiting piece is located at the edge of the working chamber; a clamping piece, the clamping piece is connected At the other end of the connecting member, the clamping members are evenly distributed around the external control mechanism outside the external control mechanism; a pushing device, the pushing device is dynamically connected to the positioning clamping part; an internal control mechanism, the internal control mechanism penetrates into the working chamber and is connected to the positioning clamping converter, the internal control mechanism and the external control mechanism are on the same axis, and the diameter of the internal control mechanism is smaller than the inner circle (hollow area) of the bearing; a driving device, the driving device is connected to the positioning clamping converter; a feeding mechanism, the feeding mechanism is arranged below the positioning clamping converter; a grinding mechanism, the grinding mechanism is arranged above the positioning clamping converter; an unloading mechanism, the unloading mechanism is arranged on the left side of the positioning clamping converter, and the feeding mechanism, the grinding mechanism, and the unloading mechanism correspond to the external control mechanism respectively.

[0008] In the above technical scheme, the embodiment of the present invention first inserts the bearing into the internal control mechanism through the feeding mechanism, and then uses the limiting piece on the limiting clamping part to press against the bearing inserted into the internal control mechanism for positioning, and then starts the pushing device to drive the limiting clamping part to rotate, so that the clamping piece on the limiting clamping part clamps the outer circle of the bearing to fix it; then starts the driving device to drive the positioning clamping converter to rotate, so that the clamped bearing rotates to the position of the grinding mechanism, and starts the grinding mechanism to grind the bearing; finally, starts the driving device to drive the positioning clamping converter to rotate, so that the polished bearing rotates to the unloading mechanism, at this time, starts the pushing mechanism to make the limiting clamping part rotate to loosen the polished bearing, and then makes the unloading mechanism unload the polished bearing, and then starts the driving device again to rotate to the feeding mechanism to repeat the above steps to realize automatic operation.

[0009] Furthermore, in an embodiment of the present invention, there is a gap between the inner control mechanism and the outer control mechanism, and the positioning and clamping converter comprises: a collecting channel, and the collecting channel is connected to the gap.

[0010] When grinding the bearing, the grinding direction is from outside to inside, so the debris is easy to concentrate in the working chamber. The debris can be discharged into the collection channel through the working chamber for centralized collection. It is not only easy to collect the waste chips for reuse, but also does not need to be cleaned regularly, which is conducive to improving production efficiency.

[0015] When grinding the bearing, first grind the inner circle of the bearing. After grinding the inner circle of the bearing, start the rotating device to drive the abutment to rotate, so that the abutment rotates around the position connected to the fixed ring, and then the abutment is tilted to abut the inner circle of the bearing. At this time, start the pushing mechanism to rotate the limit clamping part away from the outer circle of the bearing, and then the grinding mechanism grinds the outer circle of the bearing. Finally, according to the grinding needs, the outer circle of the bearing is clamped again by the limit clamping part. This is conducive to maintaining stable clamping when completely grinding the inner and outer circles of the bearing.

[0016] Furthermore, in an embodiment of the present invention, the feeding mechanism comprises: a feeding channel, which is arranged obliquely; a limiting bin, which is perpendicular to the feeding channel and connected to the feeding channel; a limiting machine, which is installed in the limiting bin; a baffle, which is perpendicular to the limiting machine, and there are at least three baffles, which are evenly distributed on the side ends of the limiting machine, and an angle is formed between the baffles, which is used to limit a bearing; an alignment bin, the left end of the alignment bin is perpendicular to the feeding channel, and the rear end of the alignment bin corresponds to the external control mechanism; a pushing cylinder, which is arranged at the front end of the alignment bin, and the telescopic end of the pushing cylinder extends into the alignment bin.

[0017] The bearings in the feeding mechanism are restricted by the baffle that forms an angle in the limiting bin. The limiting machine is started to drive the baffle to rotate and push a single bearing into the alignment bin so that the inner circle of the bearing is opposite to the inner control mechanism. Then the pushing cylinder is started to push the bearing into the inner control mechanism so that the bearing is inserted into the inner control mechanism. Each time the previous bearing is pushed by the baffle, the next bearing will roll in the inclined feeding channel of the feeding mechanism and re-enter the angle formed by the baffle.

[0018] Furthermore, in an embodiment of the present invention, the high-efficiency bearing processing device further comprises: a detection mechanism, which is arranged on the right side of the positioning and clamping converter to detect whether there is a bearing on the internal control mechanism to avoid affecting production efficiency.

[0019] Further, in an embodiment of the present invention, the grinding mechanism comprises: a mounting seat, on which a guide rail is provided; a grinding motor, on which the grinding motor is mounted; a pusher, which is connected to the grinding motor, and on which a jacket is provided, on which a directional tooth is distributed on the outer surface of the jacket;

[0021] Before grinding the bearing, start the grinding motor to drive the pusher to rotate forward, and then drive the outer grinding cylinder to move forward along the guide rail to grind the outer circle of the bearing. After the outer circle is polished, start the grinding motor to drive the pusher to rotate in the opposite direction. At this time, the outer grinding cylinder is reset, and the inner grinding cylinder moves forward along the guide column to grind the inner circle of the bearing. It is conducive to grinding the outer and inner circles of the bearing. During the grinding process, there is no need to readjust the position of the grinding knife according to the position of the outer and inner circles of the bearing, which speeds up production efficiency.

[0022] Furthermore, in an embodiment of the present invention, the unloading mechanism comprises: a cam, which is arranged at upper and lower positions in the unloading mechanism, and the cam is driven by a power device; a guide plate, which is arranged on the left side of the cam, the height of the guide plate is lower than the cam, and the guide plate is inclined; and a conveyor belt, which is arranged below the guide plate.

[0023] During the unloading process of the bearing, the power device is first started to drive the cam to rotate, and the cam squeezes the bearing and drives the bearing to separate from the internal control mechanism and the external control mechanism, so that the bearing falls onto the inclined guide plate, and then the bearing lies flat along the guide plate and falls onto the conveyor belt.

[0024] Furthermore, in an embodiment of the present invention, the high-efficiency bearing processing device also includes: an anti-rust treatment mechanism, the anti-rust treatment mechanism is arranged on the left side of the unloading mechanism, the conveyor belt passes through the anti-rust treatment mechanism, and the anti-rust treatment mechanism has: an anti-rust liquid tank, the anti-rust liquid tank has: a nozzle, the nozzle is connected to the anti-rust liquid tank, and the nozzle is located above the conveyor belt; a drying tank, the drying tank is arranged at the left end of the anti-rust liquid tank, and the drying tank has: a heater, and the heater is arranged above the conveyor belt.

[0025] After the bearing falls onto the conveyor belt, it is transported to the anti-rust liquid tank in the anti-rust treatment mechanism through the conveyor belt, and the anti-rust liquid is sprayed on the bearing through the nozzle.

[0026] Furthermore, in an embodiment of the present invention, the high-efficiency bearing processing device further includes: an air supply mechanism, which is arranged at a side end of the polishing mechanism and is used to supply air to the external control mechanism and the internal control mechanism.

[0027] The beneficial effects of the present invention are:

[0028] The present invention blocks the bearing through the limit piece of the limit clamping part, so that the bearing can be guaranteed to be in the same position each time it is installed. Then, on this basis, the limit clamping part is rotated so that the clamping piece thereon can clamp and fix the bearing, avoiding the manual operation problem of manual positioning and fixing, which is conducive to speeding up production efficiency. In addition, positioning and clamping in this way can ensure the consistency of the bearing after each installation, which is conducive to the mutual cooperation of the grinding mechanism and the unloading mechanism (no need to re-align) after the present invention rotates the positioning clamping converter, and the position is changed by rotating the positioning clamping converter, which is conducive to repeating the installation, grinding, and unloading operations of the bearing, realizing automation, and greatly improving production efficiency.

[0029] To achieve the second of the above objectives, the present invention adopts the following technical solution: a processing method, comprising the following steps:

[0030] Feeding: inserting the bearing into the internal control mechanism through the feeding mechanism;

[0031] Positioning and clamping: after the bearing is inserted into the inner control mechanism, it is pressed against the limit piece in the limit clamping part on the outer control mechanism for positioning; then the pushing device is started to drive the limit clamping part to rotate, and the limit piece presses against the bearing and is transferred to the clamping piece on the limit clamping part to clamp the outer surface of the outer circle of the bearing for fixing;

[0032] For position-changing grinding, the driving device is started to drive the positioning clamping converter to rotate, so that the clamped bearing rotates to the grinding mechanism position, and the grinding mechanism is started to grind the bearing;

[0033] To unload by changing position, start the driving device to drive the positioning clamping converter to rotate, so that the polished bearing rotates to the unloading mechanism. At this time, start the pushing mechanism to rotate the limit clamping part to release the polished bearing, and then unload the polished bearing through the unloading mechanism. Then start the driving device again to rotate to the feeding mechanism and repeat the above steps to realize automated operation.

[0034] Furthermore, in an embodiment of the present invention, when grinding a bearing, the inner circle of the bearing is ground first. After the inner circle of the bearing is ground, the rotating device is started to drive the clamping member to rotate, so that the clamping member rotates around the position connected to the fixing ring, and then the clamping member is tilted up and pressed against the inner circle of the bearing. At this time, the pushing mechanism is started to rotate the limit clamping part to disengage from the outer circle of the bearing, and then the grinding mechanism grinds the outer circle of the bearing. Finally, the outer circle of the bearing is clamped again by the limit clamping part as needed.

[0035] Furthermore, in an embodiment of the present invention, during the process of grinding the outer circle and the inner circle of the bearing, air is blown to the grinding area through the air supply mechanism, so that the debris generated by the grinding is blown through the working chamber and falls into the collection channel of the positioning and clamping converter.

[0036] Furthermore, in an embodiment of the present invention, in the feeding step, the bearings in the feeding mechanism are restricted by the baffle that forms an angle in the limiting bin, and the baffle is driven to rotate by starting the limiting machine to push a single bearing into the alignment bin so that the inner circle of the bearing corresponds to the inner control mechanism, and then the pushing cylinder is started to push the bearing into the inner control mechanism so that the bearing is inserted into the inner control mechanism, wherein each time the previous bearing is pushed by the baffle, the next bearing will roll in the inclined feeding channel of the feeding mechanism and re-enter the angle formed by the baffle.

[0037] Furthermore, in an embodiment of the present invention, before grinding the bearing, the grinding motor is started to drive the pusher to rotate forward, thereby driving the outer grinding cylinder to move forward along the guide rail to grind the outer circle of the bearing. After the outer circle is ground, the grinding motor is started to drive the pusher to rotate in the opposite direction. At this time, the outer grinding cylinder is reset, and the inner grinding cylinder moves forward along the guide column to grind the inner circle of the bearing.

[0038] Furthermore, in an embodiment of the present invention, during the process of unloading the bearing by the unloading mechanism, the power device is first started to drive the cam to rotate, thereby squeezing the bearing through the cam and driving the bearing to separate from the internal control mechanism and the external control mechanism, so that the bearing falls onto the inclined guide plate, and then the bearing lies flat along the guide plate and falls onto the conveyor belt.

[0039] Furthermore, in an embodiment of the present invention, after the bearing falls onto the conveyor belt, the bearing is conveyed to the anti-rust liquid tank in the anti-rust treatment mechanism through the conveyor belt, the anti-rust liquid is sprayed on the bearing through a nozzle, and then the sprayed bearing is conveyed to the drying tank through the conveyor belt, and the bearing is dried by a heater.

[0056] like Figure 2-4 As shown, one end of the external control mechanism 20 can be rotatably mounted on the side end of the positioning and clamping converter 10, and the external control mechanism 20 is evenly distributed on the side end of the positioning and clamping converter 10 around the center position of the positioning and clamping converter 10. The external control mechanism 20 has: a working chamber 21, a positioning and clamping portion 22, and a pushing device 27.

[0057] like Figure 4 , 5 As shown, the working cavity 21 transversely penetrates the outer control mechanism 20, and the diameter of the working cavity 21 is larger than the outer circle of the bearing. The positioning clamping part 22 is arranged at the other end of the outer control mechanism 20, and the positioning clamping part 22 includes: a connecting member 221, a limiting member 222 and a clamping member 223.

[0058] The connecting member 221 is movably connected to the external control mechanism 20. The limiting member 222 is connected to one end of the connecting member 221, and the limiting member 222 is located at the edge of the working chamber 21. The clamping member 223 is connected to the other end of the connecting member 221, and the clamping member 223 is evenly distributed outside the external control mechanism 20 around the external control mechanism 20. The pushing device 27 is dynamically connected to the positioning clamping portion 22.

[0059] The inner control mechanism 30 penetrates into the working chamber 21 and is connected to the positioning and clamping converter 10 . The inner control mechanism 30 and the outer control mechanism 20 are on the same axis. The diameter of the inner control mechanism 30 is smaller than the inner circle (hollow area) of the bearing.

[0060] like Figure 3 As shown, the driving device 40 is connected to the positioning and clamping converter 10 .

[0061] like Figure 1As shown, the feeding mechanism 50 is arranged below the positioning and clamping converter 10. The grinding mechanism 80 is arranged above the positioning and clamping converter 10. The unloading mechanism 100 is arranged on the left side of the positioning and clamping converter 10, and the feeding mechanism 50, the grinding mechanism 80, and the unloading mechanism 100 correspond to the external control mechanism 20 respectively.

[0062] Implementation steps: First, insert the bearing into the internal control mechanism 30 through the feeding mechanism 50, and then use the limiting member 222 on the limiting clamping part to press against the bearing inserted into the internal control mechanism 30 for positioning, and then start the pushing device 27 to drive the limiting clamping part to rotate, so that the clamping member 223 on the limiting clamping part clamps the outer circle of the bearing to fix it. Then start the driving device 40 to drive the positioning clamping converter 10 to rotate, so that the clamped bearing rotates to the position of the grinding mechanism 80, and start the grinding mechanism 80 to grind the bearing. Finally, start the driving device 40 to drive the positioning clamping converter 10 to rotate, so that the polished bearing rotates to the unloading mechanism 100. At this time, start the pushing mechanism to make the limiting clamping part rotate to loosen the polished bearing, and then make the unloading mechanism 100 unload the polished bearing, and then start the driving device 40 again to rotate to the feeding mechanism 50 to repeat the above steps to achieve automatic operation.

[0063] The present invention blocks the bearing through the limit piece 222 of the limit clamping part, so that the bearing can be ensured to be in the same position each time it is installed. Then, on this basis, the limit clamping part is rotated so that the clamping piece 223 thereon can clamp and fix the bearing, avoiding the manual operation problem of manual positioning and fixing, which is conducive to accelerating production efficiency. In addition, positioning and clamping in this way can ensure the consistency of the bearing after each installation, which is conducive to the mutual cooperation of the grinding mechanism 80 and the unloading mechanism 100 (without re-alignment) after the present invention rotates the positioning clamping converter 10, and the position is changed by rotating the positioning clamping converter 10, which is conducive to repeating the operation of installing, grinding, and unloading the bearing, realizing automation, and greatly improving production efficiency.

[0065] When grinding the bearing, the grinding direction is from outside to inside, so the debris is easy to gather in the working chamber 21. The debris can be discharged into the collection channel 11 through the working chamber 21 for centralized collection. It is not only easy to collect the waste chips for reuse, but also does not need to be cleaned regularly, which is conducive to improving production efficiency.

The rotating device 34 and the inner control mechanism 30 are on the same axis, and the rotating device 34 is movably connected to the first slide groove 331.

[0072] When grinding the bearing, first grind the inner circle of the bearing, after grinding the inner circle of the bearing, start the rotating device 34 to drive the abutting member 33 to rotate, so that the abutting member 33 rotates around the position connected with the fixing ring 32, and then the abutting member 33 tilts up and abuts against the inner circle of the bearing, at this time, start the pushing mechanism to rotate the limit clamping part away from the outer circle of the bearing, and then the grinding mechanism 80 grinds the outer circle of the bearing, and finally re-clamps the outer circle of the bearing through the limit clamping part according to the grinding needs. This is conducive to maintaining stable clamping when the inner and outer circles of the bearing are completely ground.

[0073] Preferably, if Figure 1 , 7As shown in FIG. 8 , the feeding mechanism 50 comprises: a feeding channel 51 , a limiting bin 52 , a limiting machine 53 , a baffle 531 , a positioning bin 54 , and a pushing cylinder 60 .
