Description

Technical Field

[0001] The present invention relates to the technical field of stamping bearing detection, in particular to a stamping bearing precision detection device. Background Art

[0002] Stamping bearing testing is the process of testing and evaluating the quality and performance of stamping bearings. Stamping bearings are widely used in various mechanical equipment. Their main function is to support and rotate mechanical parts to enable the normal operation of mechanical equipment.

[0003] The existing Chinese patent with publication number CN116336982B discloses a detection mechanism for the outer diameter snap ring groove of the outer ring of a bearing. The present invention discloses a detection mechanism for the outer diameter snap ring groove of the outer ring of a bearing, which relates to the technical field of bearing detection equipment. The following scheme is now proposed, including a machine body, a driving mechanism, the driving mechanism is installed on one side of the inner part of the machine body, and a moving mechanism, the moving mechanism is installed on the top of the machine body; the bidirectional threaded rod is driven to rotate by a motor, and the moving frame is driven to move at the same time, and the movement of the moving frame drives the synchronous movement of the clamping plate, and at the same time the motor is started to drive the linkage frame to move downward, and the linkage frame drives the sleeve to move downward while moving downward. The device can not only quickly clamp the bearing through the clamping plate, but also stably handle the bearing through the clamping plate, so as to avoid unsatisfactory detection of the outer diameter snap ring groove of the bearing outer ring due to vibration during testing, and effectively improve the accuracy of the detection of the outer diameter snap ring groove of the bearing outer ring. However, the patent can only clamp the bearing from both sides. When the outer ring accuracy of the bearing is tested, there is nothing above the bearing to press it, which causes an elasticity due to the interaction between the inner ring, outer ring and rolling element during the test.

[0004] Vibration leads to inaccurate precision detection of the bearing outer ring.

The test dial 24 can be fastened to the upper surface of the mounting plate 2 through the cover plate 25 and the mounting column 27.

[0050] Working principle: When the outer ring of the bearing needs to be tested, the bearing is placed flat on the test bench 1, and then the electric telescopic rod 432 is started, and the electric telescopic rod 432 is allowed to carry the rectangular block 433 into the docking groove. Then the motor 11 can be started to allow the bidirectional threaded rod 12 to carry the fixing component 4 to move to both sides respectively. During the movement, because one end of the connecting plate 43 is fixedly connected to the pulling block 44, when one side of the clamping plate 42 reaches the limiting groove 13, the fixing component 4 will stop in the limiting groove 13. At this time, because the bidirectional threaded rod 12 is still rotating, the internal thread A416 of the moving block 41 will move to a place where there is no thread, allowing the fixing component 4 to remain on the side of the limiting groove 13. When the fixing component 4 is not moving, the pulling block 44 will continue to move with the connecting plate 43 until the pulling block 44 is also connected to the test bench 1 When the sliding plate 434 on the side of the connecting plate 43 contacts the inner wall, the sliding plate 434 on the side of the connecting plate 43 will move from the top of the triangular groove 415 to the bottom. When the reset plate 414 is no longer pressed by the sliding plate 434, the reset plate 414 will be bounced up by the spring A413. Because the belt 454 inside the pressure plate 45 is fixedly connected to the reset plate 414, the belt 454 inside the pressure plate 45 will be in a relaxed state while the reset plate 414 rises. At this time, the extension plate 456 and the tension spring 455 are no longer pulled by the belt 454. The tension spring 455 will pop out the extension plate 456, allowing the extension plate 456 to extend with the silicone pad 457. As the card plate 42 is attached to the inner wall of the limit groove 13, the docking plate 424 on the side of the card plate 42 will retract to the inner wall of the card plate 42 due to contact with the inner wall of the bearing inner ring. Because one side of the docking plate 424 is fixedly connected to the inclined slide plate 422, when the docking plate 424 is retracted to the card plate 42 When the bearing is fixed, the extension plate 456 and the silicone pad 457 will firmly press the upper surface of the bearing inner diameter. In the process of the bearing being fixed, the other group of fixing components 4 is longer because the connecting plate 43 is longer. Therefore, the pull block 44 of the fixing component 4 of this group will contact the pressure handle 54 of the air blowing component 5 when moving, so that the gas inside the gas supply rod 52 moves to the inside of the gas pipe 55 and finally blows to the top of the bearing, so that the bearing rotates automatically. After that, it is tested by the test dial 24. When it is necessary to test other matters of the bearing and it also needs to be fixed, the sleeve rod 51 is rotated to allow the block 513 of the sleeve rod 51 to enter the rectangular groove 511. At this time, the air blowing component 5 can be moved to the bottom groove 35. Inside, at this time, when the fixing component 4 is started, the bearing can be fixed. When the test dial 24 needs to be replaced, it is only necessary to rotate the mounting column 27 half a circle to allow the rectangular plate 29 to rotate from the arc groove 23 to the bottom of the mounting groove 22, and then the cover plate 25 can be flipped over.This achieves the effect of fastening the bearing to the test bench 1 to prevent bearing vibration when testing the outer ring of the bearing.
