[0044] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0045] like Figure 1-5 As shown, the present invention provides a fully automatic flaw detection equipment for bearing inner rings, including a feeding device 1, a flaw detection device 2 installed at the end of the feeding device 1, a demagnetizing and cleaning device 3 arranged in parallel and staggered with the flaw detection device 2, a transfer detection device 4 installed between the flaw detection device 2 and the demagnetizing and cleaning device 3, and a feeding device 5 arranged at the end of the demagnetizing and cleaning device 3.

[0046] in,

[0047] The feeding device 1 includes a feeding rack 11, a feeding line 12 installed on the feeding rack 11, a plurality of contouring fixtures 13 installed on the feeding line 12, and bearing inner rings are installed in pairs on the contouring fixtures 13 and conveyed to the flaw detection device 2 along with the feeding line 12.

[0048] The flaw detection device 2 includes a flaw detection frame 21, a roller assembly 22 mounted on the flaw detection frame 21 and arranged facing the contour tooling 13, longitudinal coils 23 mounted at both ends of the roller assembly 22, and a through rod 24 that can be inserted into the longitudinal coils 23. A clamping device 6 is also mounted on the flaw detection frame 21 for clamping the bearing inner ring on the contour tooling 13 to the roller assembly 22.

[0049] The demagnetizing and cleaning device 3 includes a demagnetizing frame 31 arranged in parallel with the flaw detector 21, a conveyor line 32 arranged along the length of the demagnetizing frame 31, and a demagnetizing mechanism 33, a cleaning mechanism 34 and a drying mechanism 35 arranged along the conveying direction of the conveyor line 32. A discharge port is provided on one side of the drying mechanism 35, and the discharge port is connected to the unloading device 5. A pushing mechanism 36 is installed on the demagnetizing frame 31 on the opposite side of the discharge port.

[0050] The transfer detection device 4 includes a multi-axis robot 41, a transfer seat 42 mounted on the execution end of the multi-axis robot 41, and detection components 43 and transfer components 44 mounted on both ends of the transfer seat 42.

[0051] The working principle and beneficial effects of the above embodiments are as follows:

[0052] This utility model discloses a fully automatic flaw detection device for bearing inner rings. The bearing inner rings are installed in pairs on the contour tooling 13 of the feeding device 1 and transported to the location of the flaw detection device 2 by the feeding line 12.

[0053] The clamping device 6 clamps the bearing inner ring on the contour tooling 13 onto the roller assembly 22. The roller assembly 22 drives the bearing inner ring to rotate, and the through rod 24 passes through the bearing inner ring. The longitudinal coils 23 at both ends cooperate to perform flaw detection on the bearing inner ring.

[0054] The multi-axis robot 41 of the transfer and inspection device 4 drives the transfer seat 42 to move. The inspection component 43 on one side performs surface inspection on the inner ring of the bearing after flaw detection with the cooperation of the roller assembly 22. The transfer component 44 on the other side transfers the inspected inner ring of the bearing from the roller assembly 22 to the conveyor line 32 of the demagnetizing and cleaning device 3.

[0055] The bearing inner ring on the conveyor line 32 is sequentially conveyed to the demagnetizing mechanism 33, the cleaning mechanism 34 and the drying mechanism 35. After the demagnetizing, cleaning and drying are completed, the pushing mechanism 36 pushes the bearing inner ring from the discharge port to the unloading device 5.

[0056] This utility model features fully automated operation from material loading to flaw detection, inspection, transfer, demagnetization, cleaning, air drying to unloading, reducing manual intervention, improving production efficiency and product quality;

[0057] This utility model provides accurate and reliable flaw detection and testing. Flaw detection is achieved through the cooperation of longitudinal coil 23 and through rod 24, resulting in high accuracy. Combined with the detection of transfer detection device 4, it reduces the rate of missed and false detections.

[0058] The demagnetizing and cleaning device 3 of this utility model integrates demagnetizing, cleaning and air drying functions. The equipment has a compact layout, saves workshop space and simplifies the production process.

[0059] In one embodiment,

[0060] like Figure 6 As shown, the clamping device 6 includes a clamping seat 61 mounted on the flaw detector frame 21, a lead screw 62 mounted on one side of the clamping seat 61, a slider 63 rotatably mounted on the lead screw 62, a first lifting cylinder 64 mounted on the slider 63 and arranged vertically, and a clamping assembly 65 mounted on the telescopic end of the first lifting cylinder 64.

[0061] The clamping assembly 65 includes a clamping plate 651 installed at the telescopic end of the first lifting cylinder 64, a stop block 652 installed at the lower end of the clamping plate 651 and located in the middle, and drag claws 654 installed on both sides of the stop block 652 and driven by the transverse cylinder 653 to move relative to the stop block 652.

[0062] When the lead screw 62 rotates, it drives the slider 63 to move along the axis of the lead screw 62, so that it is aligned with the bearing inner ring of the contour tooling 13. When the first lifting cylinder 64 extends and retracts, it adjusts the vertical position of the clamping assembly 65 to adapt to the picking and placing height of the bearing inner ring.

[0063] When the clamping assembly 65 moves to the position of the inner ring of the bearing, the stop block 652 is located between the two inner rings of the bearing. The transverse cylinders 653 on both sides drive the drag claw 654 to move towards the stop block 652. The drag claw 654 supports the inner ring of the bearing and makes the inner ring of the bearing abut against the stop block 652, thus completing the gripping.

[0064] After the bearing inner ring is grasped, it is moved to the top of the roller assembly 22 by the cooperation of the lead screw 62 and the first lifting cylinder 64. The transverse cylinder 653 moves in the opposite direction to release the drag claw 654, thus completing the placement of the bearing inner ring.

[0065] The stop block 652 is positioned in the center and works in sync with the drag claws 654 on both sides to grip the inner rings of the bearings placed in pairs, preventing them from falling off or shifting during the transfer process.

[0066] In one embodiment,

[0067] like Figure 7 As shown, the above-mentioned detection component 43 includes a detection seat 431 mounted on the transfer seat 42 and a detection camera 432 mounted on the detection seat 431;

[0068] The detection component 43 moves with the transfer seat 42 of the multi-axis robot 41. When the transfer seat 42 is adjusted to be above the roller assembly 22 of the flaw detection device 2, the detection seat 431 drives the detection camera 432 to align with the bearing inner ring that has been flaw-detected on the roller assembly 22. The detection camera 432 acquires images of the bearing inner ring surface. After the detection is completed, the detection component 43 feeds back the result signal to the control system, providing a basis for judgment for the subsequent action of the transfer component 44.

[0069] In one embodiment,

[0070] like Figure 8 As shown, the above-mentioned transfer component 44 includes a transfer seat 441 mounted on the transfer seat 42, a bidirectional cylinder 442 mounted on the lower end of the transfer seat 441, and two inner support heads 443 mounted on the output end of the bidirectional cylinder 442. The two inner support heads 443 clamp the inner hole of the bearing inner ring under the drive of the bidirectional cylinder 442.

[0071] A protrusion is provided on the inner support head 443 on one side, and a groove for sliding the protrusion is provided on the transfer seat 441.

[0072] The aforementioned transfer seat 42 is plate-shaped, which facilitates its insertion into the space on both sides of the idler roller assembly 22 to assist the transfer component 44 in picking up materials;

[0073] The transfer component 44 extends into the space on both sides of the roller assembly 22 along with the transfer seat 42. The multi-axis robot 41 drives the transfer seat 441 to move, so that the two inner support heads 443 are aligned with the inner hole of the bearing inner ring. The bidirectional cylinder 442 is activated, driving the two inner support heads 443 to expand outward synchronously, and to support and fix them from the inside of the inner hole of the bearing inner ring. Among them, the protrusion of one inner support head 443 slides along the groove of the transfer seat 441 to ensure that the expansion action is smooth and precise.

[0074] After clamping is completed, the multi-axis robot 41 drives the transfer seat 42 to move as a whole, transferring the bearing inner ring from the roller assembly 22 to above the conveyor line 32 of the demagnetizing and cleaning device 3;

[0075] The bidirectional cylinder 442 moves in the opposite direction, and the two inner support heads 443 retract and disengage from the inner hole of the bearing inner ring, completing the placement of the workpiece. The transfer component 44 sequentially transfers the two bearing inner rings on the roller assembly 22 to the conveyor line 32.

[0076] The plate-shaped transfer seat 42 can flexibly extend into the narrow space on both sides of the roller assembly 22, solving the problem of limited material picking position; the cooperation structure of the protrusion and groove ensures the stable operation of the inner support head 443 and improves the clamping accuracy.

[0077] In one embodiment,

[0078] like Figure 9 As shown, the above-mentioned demagnetizing mechanism 33 includes a portal frame 331 mounted on the demagnetizing frame 31, a second lifting cylinder 332 mounted on the portal frame 331 and arranged vertically, a guide frame 333 mounted on the extension end of the second lifting cylinder 332 and placed inside the portal frame 331, and a U-shaped magnetic yoke 334 mounted below the guide frame 333 and arranged facing the conveyor line 32.

[0079] The demagnetizing mechanism 33 also includes a U-shaped magnetic yoke 335 mounted on the demagnetizing frame 31 and placed at the lower end of the conveyor line 32. The U-shaped magnetic yoke 334 is pushed vertically through the inner ring of the bearing on the conveyor line 32 by the second lifting cylinder 332 and contacts the U-shaped magnetic yoke 335.

[0080] The conveyor line 32 transports the inspected bearing inner ring to the lower part of the portal frame 331, positioning it directly above the straight magnetic yoke 335. The second lifting cylinder 332 extends, pushing the guide frame 333 and the U-shaped magnetic yoke 334 below it to descend vertically. The U-shaped magnetic yoke 334 passes through the inner hole of the bearing inner ring on the conveyor line 32 until it contacts the straight magnetic yoke 335 below, forming a closed magnetic circuit. When the U-shaped magnetic yoke 334 and the straight magnetic yoke 335 are energized, they generate an alternating magnetic field. By gradually reducing the magnetic field strength, the magnetism of the bearing inner ring gradually disappears, completing the demagnetization. After demagnetization is completed, the second lifting cylinder 332 retracts, driving the U-shaped magnetic yoke 334 to rise and detach from the bearing inner ring. The conveyor line 32 then transfers the demagnetized bearing inner ring to the next process.

[0081] The magnetic yoke's movement is matched with the conveying rhythm of the conveyor line 32. The demagnetization process does not affect the overall assembly line speed, ensuring the equipment's continuous operation efficiency.

[0082] In one embodiment,

[0083] The aforementioned conveyor line 32 is arranged as a chain plate line, and clearance grooves are provided at equal intervals on the chain plate line. The bearing inner ring is placed on the chain plates on both sides of the clearance groove via the transfer component 44. The width of the clearance groove is greater than the thickness of the U-shaped magnetic yoke 334, providing vertical space for the U-shaped magnetic yoke 334 to pass through. When the demagnetizing mechanism 33 is working, the U-shaped magnetic yoke 334 can pass through the clearance groove, accurately enter the inner hole of the bearing inner ring, and connect with the straight magnetic yoke 335 below, ensuring the formation of a closed magnetic circuit and guaranteeing the demagnetizing effect.

[0084] In one embodiment,

[0085] The cleaning mechanism 34 includes a cleaning hood installed on the demagnetizing frame 31 and open at both ends, a spray pipe installed inside the cleaning hood and arranged along the width direction of the conveyor line 32, and a water receiving tray installed at the lower end of the demagnetizing frame 31. A curtain is installed at the two open ends of the cleaning hood.

[0086] After being demagnetized, the inner ring of the bearing enters the cleaning hood along the conveyor line 32. The curtains at both ends of the cleaning hood hang down naturally, forming a relatively enclosed space to reduce the splashing of cleaning fluid. The spray pipes arranged along the width of the conveyor line 32 inside the cleaning hood spray cleaning fluid onto the inner ring of the bearing to rinse away any remaining impurities and oil stains on its surface, ensuring that the surface is clean. After cleaning, the inner ring of the bearing passes through the curtain at the other end along the conveyor line 32, leaves the cleaning area, and enters the next process.

[0087] In one embodiment,

[0088] The aforementioned drying mechanism 35 includes a drying rack mounted on the demagnetizing frame 31, a fan mounted on the top of the drying rack, and the drying rack having openings around its perimeter.

[0089] After cleaning, the inner ring of the bearing enters the drying rack along the conveyor line 32. Since the drying rack is open on all sides, air can circulate freely. The fan installed on the top of the drying rack starts and generates a downward airflow, which accelerates the evaporation of moisture on the surface of the inner ring of the bearing, quickly removes residual moisture, and avoids moisture residue from causing the workpiece to rust or affecting subsequent processes.

[0090] In one embodiment,

[0091] The aforementioned pushing mechanism 36 includes a push plate 361 installed on one side of the demagnetizing frame 31, and a pushing cylinder 362 connected to the push plate 361. The pushing cylinder 362 pushes the inner rings of two bearings placed side by side at the end of the conveyor line 32 onto the unloading device 5.

[0092] After the two parallel bearing inner rings are air-dried, the pusher cylinder 362 extends and drives the pusher plate 361 to move towards the discharge port at the end of the conveyor line 32. After the pusher plate 361 contacts the bearing inner rings, it pushes the two parallel bearing inner rings onto the unloading device 5 simultaneously.

[0093] The pusher cylinder 362 drives the pusher plate 361, which has a rapid response and uniform pushing force, ensuring that the two parallel bearing inner rings enter the feeding device 5 synchronously and smoothly.

[0094] In one embodiment,

[0095] The above-mentioned unloading device 5 includes an unloading frame 51, an unloading line 52 installed on the unloading frame 51, and a V-shaped limiting block 53 installed at the end of the unloading line 52. The bearing inner ring is conveyed to the unloading line 52 and is limited by the V-shaped limiting block 53 at its end.

[0096] The bearing inner ring pushed by the feeding mechanism 36 enters the unloading line 52 and moves towards the end with the conveying power of the unloading line 52, realizing a smooth transition from the demagnetizing and cleaning device 3 to the unloading area. When the bearing inner ring is conveyed to the end of the unloading line 52, the V-shaped limit block 53 guides the bearing inner ring to the center and limit it, ensuring that the workpiece stays stably in the preset position. The bearing inner ring after being limited can be collected manually.

[0097] In summary:

[0098] This utility model discloses a fully automatic flaw detection and testing device for bearing inner rings. From loading to flaw detection, testing, transfer, demagnetization, cleaning, air drying to unloading, the entire process is automated, reducing manual intervention, improving production efficiency, and enhancing product quality.

[0099] This utility model provides accurate and reliable flaw detection and testing. It achieves flaw detection through the combination of longitudinal coil and through rod, resulting in high accuracy. Combined with the detection of the transfer detection device, it ensures that the detection conditions of each bearing inner ring are consistent, reducing the rate of missed and false detections and improving the quality stability of the workpiece.

[0100] This utility model's demagnetizing and cleaning device integrates demagnetizing, cleaning, and drying functions, ensuring continuous and efficient operation of each process. The equipment layout is compact, saving workshop space and simplifying the production process.
