Technical Field

[0001] The present application relates to the technical field of bearing processing equipment, and in particular to a bearing ring turning and conveying equipment. Background Art

[0002] Bearings are a crucial component in mechanical equipment. Their primary function is to support rotating parts, reduce friction during movement, and ensure rotational accuracy. There are many types of bearings, all of which generally consist of an inner ring, an outer ring, and rolling elements. The inner and outer rings are collectively referred to as bearing rings.

[0003] Taking a ball bearing as an example, the inner ring of the bearing has an arc groove on its circumferential outer wall, and the outer ring has an arc groove on its circumferential inner wall. During the machining process, the bearing rings are turned on a lathe. Typically, the bearing rings are manually mounted on the lathe's triangular chuck, and one end of the bearing ring is turned using a pre-set program. The bearing ring is then removed and reinstalled, and the other end is turned, completing the lathe process.

[0004] This machining method has the following problems: low efficiency in bearing conveying, installation, turning, and disassembly, long manual operation time, and potential safety hazards. Therefore, it is necessary to design an automated equipment that can improve the efficiency, accuracy, and safety of bearing ring turning. Summary of the Invention

[0033] In summary, this application includes at least one of the following beneficial technical effects:

[0034] 1. The first slide drives the pneumatic gripper to grab the bearing ring on the material handling table and move it to the first lathe. The pneumatic gripper facing the chuck removes the processed bearing ring from the chuck. The double-end seat rotates to place the new bearing seat on the chuck and moves it upward. The pneumatic gripper places the bearing ring processed on one end on the relay table. The flip motor drives the pneumatic finger to flip over the relay table to clamp the bearing ring and then flip it to the receiving table. The second slide drives the pneumatic gripper to grab the bearing ring and move it to the second lathe, where it is fixed on the clamping plate for processing on the other end. The completely processed bearing ring is removed and placed on the unloading table, completing the automatic turning process of the bearing ring at both ends.

[0035] 2. When the pneumatic gripper grabs the bearing ring, the detection plate contacts the bearing ring and compresses the compression spring. The pressure sensor contacts the detection plate. The pressure sensor's value is used to monitor whether the pneumatic gripper is stably grasping the bearing ring and whether its state is deviated, thereby improving the gripping effect of the bearing ring.

[0036] 3. The double-end seat setting can realize the position conversion of the two pneumatic grippers, and then can simultaneously realize the removal of the bearing ring on the clamping plate and the installation of the new bearing ring on the chuck, thereby improving processing efficiency;

[0037] 4. The setting of the adjustment plate can realize the position adjustment of the abutment block, thereby being able to clamp bearing rings of different sizes. At the same time, the adjustment groove and the stabilizing bar hole can effectively improve the stability of the abutment block position;

[0038] 5. The protective box not only reduces the impact of debris flying upwards during turning and affecting the normal movement of the pneumatic gripper through the bottom plate, but also provides installation space for the drying plate and chassis. The bearing ring removed from the chuck can be dried and removed from the turning fluid in the protective box. This process is completed during the upward movement of the pneumatic gripper, improving the efficiency and quality of bearing ring turning.

[0039] 6. When the air pipe provides air to the air cavity, the pressure will drive the extension tube to move upward, so that the inner blowing plate moves into the bearing ring, and then the circumferential inner wall of the bearing ring can be dried by the gas ejected from the inner blowing ring groove. In this way, after the base plate is buckled, it is only necessary to slowly drive the pneumatic gripper upward to dry the circumferential inner and outer walls of the bearing ring at the same time, without the need for additional downward movement, which effectively improves the efficiency and effect of removing the turning fluid on the bearing ring.

DETAILED DESCRIPTION

[0048] The following is combined with Figure 1-7 This application is described in further detail.

[0049] The embodiment of the present application discloses a bearing ring turning and conveying device.

[0050] refer to Figure 1 The bearing ring turning and conveying equipment includes a first lathe 1, a second lathe 2, a guide rail beam 3, a mounting platform 4, a material retrieving platform 5, and an unloading platform 6. The first and second lathes 1 and 2 are identical in structure, both being automatic lathes. The chucks of the lathes are vertically positioned, and above the chuck of the first lathe 1 is a feed channel 11 for transporting bearing rings. The guide rail beam 3 is horizontally mounted above the first and second lathes 1 and 2.

[0051] refer to Figure 1 and Figure 2 The retrieving platform 5 is located on the side of the first lathe 1 away from the second lathe 2, for placing unprocessed bearing rings. A first conveyor belt 51 is provided on one side of the retrieving platform 5. The plane of the retrieving platform 5 holding the bearing rings is tilted toward the first conveyor belt 51, so that the bearing rings can slide obliquely onto the first conveyor belt 51. A baffle 52 is fixed at the end of the first conveyor belt 51. The frame of the first conveyor belt 51 near the end is rotatably connected to a shift plate 53. The shift plate 53 is driven by a motor to rotate and can intercept the bearing rings. The unloading platform 6 is set on the side of the second lathe 2 away from the first lathe 1, for placing completely processed bearing rings. The part of the unloading platform 6 holding the bearing rings is a conveyor belt.

[0052] refer to Figure 1 and Figure 3 The guide beam 3 is equipped with a first slide 31 and a second slide 32, both of which are cross-type electric slides. The first slide 31 is located above the first lathe 1 and the reclaiming platform 5, while the second slide 32 is located above the second lathe 2 and the unloading platform 6. The mounting platform 4 is mounted at the bottom end of the vertical sliding portion of the first and second slides 31 and 32. The bottom of the mounting platform 4 is rotatably connected to a double-end seat 41 driven by a motor. The two ends of the double-end seat 41 form a 90° angle and are both equipped with pneumatic grippers 42. The rotation axis of the double-end seat 41 is tilted, with one end of the double-end seat 41 facing downward and the other end capable of facing the chuck of the corresponding lathe. A flip assembly 7 for flipping the bearing ring is installed between the first and second lathes 1 and 2 on the guide beam 3. The first slide 31 can use its own pneumatic gripper 42 to grab the bearing ring from the reclaiming platform 5 and move it to the chuck of the first lathe 1. It can also be moved to the flip assembly 7. The second slide 32 can drive its own pneumatic gripper 42 to move to the flip assembly 7, the chuck of the second lathe 2 and the unloading platform 6. Figure 2 A drying assembly 8 for removing the turning fluid on the bearing ring is provided in the feeding channel 11 of the first lathe 1 and the second lathe 2.

[0053] Multiple bearing rings are placed on the pick-up platform 5 and moved via an inclined surface to the first conveyor belt 51, where they are driven by the first conveyor belt 51 to move toward the baffle 52. By rotating the selector plate 53, only one bearing ring is allowed to pass through and abut against the baffle 52. The first slide 31 drives its downward-facing pneumatic gripper 42 to move above the bearing ring abutting against the baffle 52 and grasp the bearing ring. The first slide 31 then drives the mounting platform 4 through the feed channel 11 to the chuck of the first lathe 1. Another pneumatic gripper 42 on the double-end seat 41 removes the bearing ring, which has been turned on one end, from the chuck. The double-end seat 41 is then rotated to secure a new bearing ring to the chuck. The first slide 31 drives the mounting platform 4 upward, and during this movement, the drying assembly 8 removes the turning fluid from the bearing ring. The first slide 31 drives the mounting platform 4 to the flipping assembly 7, where it lowers the bearing ring. The flipping assembly 7 then flips the bearing ring. The second slide 32 drives its own pneumatic gripper 42 to move to the flipping assembly 7, grab the flipped bearing ring, and move it to the chuck of the second lathe 2. First, another pneumatic gripper 42 on the double-end seat 41 is used to remove the fully turned bearing ring from the chuck. The double-end seat 41 is then rotated to fix the bearing ring with one end turned on the chuck for turning the other end. Finally, the second slide 32 drives the pneumatic gripper 42 to move to the unloading platform 6 to lower the turned bearing ring. As the bearing ring passes through the drying assembly 8, the turning fluid on the bearing ring is dried. This allows the turning process of both ends of the bearing ring to be automatically completed, improving processing efficiency and quality.

[0054] refer to Figure 3 The flipping assembly 7 includes a relay platform 71, a flipping motor 72 and a receiving platform 73. The relay platform 71 is set on one side of the guide rail beam 3 for the bearing ring to be placed horizontally. The flipping motor 72 is installed on one side of the relay platform 71, and the rotating shaft is set horizontally and is equipped with a pneumatic finger 721. The gripper of the pneumatic finger 721 is extended through the frame and can clamp the circumferential outer wall of the bearing ring. The pneumatic finger 721 can clamp and fix the circumferential outer wall of the bearing ring on the relay platform 71. The receiving platform 73 is set on the side of the flipping motor 72 away from the relay platform 71. After the pneumatic finger 721 is flipped, the bearing ring can be placed on the receiving platform 73. In this embodiment, the receiving platform 73 is a conveyor belt structure, and there is a frame structure at the end of the conveyor belt of the receiving platform 73 to intercept the bearing ring. The conveyor belt structure of the receiving platform 73 can ensure that the position where the bearing ring is grasped on the receiving platform 73 maintains a certain distance from the pneumatic finger 721, thereby not affecting the normal flipping of the pneumatic finger 721, and not being affected by the pneumatic finger 721 in grasping the bearing ring.

[0055] refer to Figure 4The pneumatic gripper 42 is a three-claw gripper, and the gripping part of the pneumatic gripper 42 is located on its own driving block. An adjustment slot 422 is provided on the driving block of the pneumatic gripper 42, and the adjustment slot 422 is located at a position where the driving block of the pneumatic gripper 42 is away from the center of the pneumatic gripper 42. An adjustment plate 423 is slidably connected in the adjustment slot 422, and the sliding direction of the adjustment plate 423 is perpendicular to the central axis of the pneumatic gripper 42. Abutment blocks 4232 are fixedly provided on the adjustment plate 423 near the central axis of the pneumatic gripper 42. The abutment blocks 4232 are the part of the pneumatic gripper 42 that grips the bearing ring. The adjustment plate 423 is provided with a plurality of insertion holes 4231, and the inner wall of the adjustment slot 422 is provided with a plurality of mounting holes 4221. The mounting holes 4221 are threaded holes. After the bolts pass through the insertion holes 4231, they are threadedly connected to the mounting holes 4221 and tightly abut against the adjustment plate 423. The pneumatic gripper 42 has a stabilizing bar hole 424 in the middle of its drive block. This hole 424 communicates with the adjustment slot 422 and is located near the center axis of the pneumatic gripper 42. An abutment block 4232 is located on the adjustment plate 423 near the stabilizing bar hole 424 and abuts against the inner wall of the hole. This allows the abutment block 4232 to be adjusted to accommodate bearing rings of varying diameters for stable gripping. The arrangement of the adjustment slot 422 and stabilizing bar hole 424 effectively improves the stability of the abutment block 4232. The pneumatic gripper is equipped with a detection component to monitor the gripping status of the bearing ring.

[0056] The detection assembly includes a mounting plate 4211, a pressure sensor 4212, a compression spring 4213 and a detection plate 4214. There are three mounting plates 4211, which are installed on the base of the pneumatic gripper 42. The mounting plates 4211 are located between the drive blocks that start the gripper. The pressure sensor 4212 is installed on the mounting plate 4211. There are multiple compression springs 4213, which are installed on the mounting plate 4211. The other ends of the multiple compression springs 4213 are fixedly connected to the same detection plate 4214. When the abutment block 4232 is clamped with the circumferential outer wall of the bearing ring, the bearing ring is pressed against the detection plate 4214 and contacts the pressure sensor 4212. In this way, it is possible to detect whether the clamped bearing ring is clamped stably and correctly, thereby reducing the occurrence of bearing ring deviation.

[0057] refer to Figure 5 and Figure 6The drying assembly 8 includes a drying tray 81, a base tray 82, an extension tube 83, and an inner blowing tray 84. The feed channel 11 is equipped with a protective box 111. A bottom plate 112 is slidably connected to the bottom of the protective box 111. The bottom plate 112 is driven to slide horizontally by a telescopic cylinder mounted on one side of the protective box 111. The bottom plate 112 can slide to positions that completely close the bottom of the protective box 111 and completely open the bottom of the protective box 111. Both ends of the bottom plate 112 are tilted downward to form drainage points 1121, which do not contact the protective box 111. The drying tray 81 is mounted within the protective box 111. A drying ring cavity 811 is defined along the inner circumference of the drying tray 81. The width of the drying ring cavity 811 gradually decreases from the inside to the opening and is tilted downward. Multiple air pipes 812 connected to an air pump are mounted on the outer circumference of the drying tray 81. The air pipes 812 are connected to the drying ring cavity 811. The drying tray 81 is passed through by the mounting platform 4.

[0058] refer to Figure 6 and Figure 7 The chassis 82 is mounted on the upper surface of the base plate 112, and an air cavity 821 is provided at the top of the chassis 82. The air pipe 812 is also mounted on the chassis 82 and communicates with the bottom of the air cavity 821. An anti-slip ring plate 831 is fixed at the bottom of the extension tube 83, and the anti-slip ring plate 831 abuts against the inner wall of the air cavity 821 and slides vertically, and the extension tube 83 is arranged vertically. A plurality of limit blocks 8211 are fixed at the top and bottom of the circumferential inner wall of the air cavity 821 to limit the anti-slip ring plate 831. An exhaust hole 8212 communicating with the outside is provided on the inner wall of the air cavity 821 above the limit block 8211 at the top of the air cavity 821, and the connection between the air pipe 812 and the air cavity 821 is located below the limit block 8211 at the bottom of the air cavity 821. The inner blowing plate 84 is mounted on the top of the extension tube 83, and an inner blowing ring groove 841 is provided on the circumferential outer wall of the inner water tray. The inner blowing ring groove 841 gradually decreases in width from the inside out and is tilted downward from the inside out. It communicates with the air cavity 821 via the extension tube 83. After the bottom plate 112 seals the bottom of the protective box 111, the central axes of the inner blowing plate 84 and the drying plate 81 are aligned. The inner blowing plate 84 is positioned below the center of the bearing ring grasped by the upper pneumatic gripper 42. The sidewalls of the protective box 111 are positioned to avoid the inner blowing plate 84 and the extension tube 83.

[0059] The center of the detection plate 4214 extends out of the way of the pneumatic gripper 42. When the air pipe 812 vents the air cavity 821, the inner blow plate 84 moves upward, allowing it to reach a position where the outlet of the inner blow ring groove 841 is located above the upper surface of the bearing ring gripped by the pneumatic gripper 42. The top of the inner blow plate 84 is counterweighted with metal. When the air cavity 821 stops venting, the gravity of the inner blow plate 84 and the extension tube 83 resets the inner blow plate 84.

[0060] After the mounting platform 4 moves onto the protective box 111 and stops, the bearing ring grasped by the pneumatic gripper 42 is now positioned below the drying plate 81 and above the inner blowing plate 84. Air is then supplied by the air pipe 812, and the drying plate 81 ejects the air downward through the drying ring cavity 811. The air from the air pipe 812 lifts the inner blowing plate 84, causing the anti-slip ring plate 831 to abut against the uppermost stopper 8211. The inner blowing plate 84 now passes through the middle of the bearing ring and is positioned above it. The air in the air cavity 821 is blown downward through the inner blowing ring groove 841, and then onto the top of the circumferential inner wall of the bearing ring. The mounting platform 4 then moves upward, driving the bearing ring upward. The gas blown out from the inner blowing ring cavity sweeps across the circumferential inner wall of the bearing ring from top to bottom; the gas blown out from the drying ring groove sweeps across the circumferential outer wall of the bearing ring from top to bottom, thereby achieving the drying process of the bearing ring during the upward movement of the mounting platform 4. The turning fluid in the grooves on the circumferential inner wall or circumferential outer wall of the bearing ring can also be efficiently removed. The blown-away turning fluid falls on the bottom plate 112 and is discharged from the protective box 111 through the drain 1121. The pneumatic gripper 42 grabs the bearing ring and moves it to the corresponding lathe chuck for replacement, and then moves it to the position where the bearing ring needs to be lowered. This takes 30-40 seconds, of which the time in the protective box 111 is 8-10 seconds.

[0061] The implementation principle of the bearing ring turning and conveying equipment of the embodiment of the present application is as follows: the first slide 31 drives the pneumatic gripper 42 to move to the material-retrieving platform 5 to grab the bearing ring, the first slide 31 drives the mounting platform 4 to move upward and move to the top of the feeding channel 11 of the first lathe 1 and then downward, so that the horizontal pneumatic gripper 42 removes the bearing ring from the chuck of the first lathe 1, the double-end seat 41 rotates, and the new bearing ring is placed on the chuck of the first lathe 1 through the pneumatic gripper 42, and then the first slide 31 drives the mounting platform 4 to move upward into the protective box 111. After the pneumatic gripper 42 moves inward to the protective box, it stops moving, the bottom plate 112 extends, and then the air pipe 812 is ventilated to push out the extension pipe 83, and the first lathe 1 drives the pneumatic gripper 42 to gradually move upward, and then the air blown out by the drying plate 81 and the inner blowing plate 84 clears the turning fluid on the outer surface of the bearing ring. Then the first slide 31 drives the pneumatic gripper 42 to be positioned above the relay platform 71 to lower the bearing ring that has been processed at one end.

[0062] The flip motor 72 drives the pneumatic finger 721 to rotate and grab the bearing ring from the relay platform 71 to the receiving platform 73. Then the second slide 32 drives the pneumatic gripper 42 to move to the receiving platform 73 to grab the bearing ring and move it to the chuck of the second lathe 2. The bearing ring with both ends processed on the second lathe 2 is removed by another pneumatic gripper 42 on the second slide 32. The double-end seat 41 rotates and fixes the bearing ring with one end processed to the chuck of the second lathe 2 through the pneumatic gripper 42. Then the second slide 32 drives the pneumatic gripper 42 to move upward, and clears the turning fluid in the protective box 111. Finally, it moves to the unloading platform 6 to put the bearing ring down, completing the automatic double-end turning process of a bearing ring, thereby improving the efficiency of bearing ring turning.

[0063] The embodiments of this specific implementation method are all preferred embodiments of the present application and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
