Its characteristics are small frictional resistance and high rotational speed. It can be used on parts that can withstand radial loads or combined loads with both radial and axial actions simultaneously, and can also be used on parts that can withstand axial loads, such as small power motors, automotive and tractor gearboxes, machine tool gearboxes, general machinery, tools, etc. The deep groove ball bearing is the most common type among rolling bearings. During the production process of deep groove ball bearings, strength detection is required, and strength detection equipment will be used during the strength detection.

When a component deviating from the central axis of the pressing device is detected, it is easy to generate a bias pressure inside the detection equipment, resulting in deformation or damage of the device. Moreover, the detection equipment does not have a corresponding protection structure, and the broken pieces of the component damaged by the strength detection will fly and cause harm to the surrounding operators, which is not conducive to people's use. Therefore, the technical personnel in this field have provided a strength detection device for deep groove ball bearings to solve the problems raised in the above background technique.

Specific implementation manners
[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.
[0022] Please refer to Figures 1 to 4 , in the embodiment of the present utility model, a strength detection device for deep groove ball bearings includes an equipment box 1. The four corners of the top of the equipment box 1 are connected with a pressurizing component through round rods 2. A column 3 is installed at the center of the top of the equipment box 1. The top of the column 3 is welded with a detection table 4 corresponding to the pressurizing component. A protective net 5 for sleeving around the outer circle of the detection table 4 is detachably connected to the pressurizing component. A disc-shaped support plate 6 is installed on the outer circle of the column 3. A plurality of deviation correction members that are slidably installed inside the disc-shaped support plate 6 and are arranged at equal circumferential intervals around its central axis and whose tops are telescopic are provided. The tops of the deviation correction members extend above it through a first chute 7 opened inside the detection table 4. A driving member for controlling the simultaneous movement of a plurality of deviation correction members is rotatably installed on the outer circle of the support plate 6.
[0023] When the strength detection device for deep groove ball bearings is in use, the deep groove ball bearing components to be detected are placed on the top of the detection table 4. The driving member is started to drive the deviation correction members to displace. A plurality of deviation correction members can conveniently correct the components to the center of the top of the detection table 4. The downward pressing component is started. The downward pressing component can drive the protective net 5 to move simultaneously. When the downward pressing component contacts the tops of the deviation correction members and continues to displace, the bottoms of the deviation correction members can be moved downward. The downward pressing component can pressurize the components for strength detection. The protective net 5 is sleeved around the outer circle of the detection table 4, which can effectively prevent the broken component debris from splashing everywhere.
[0024] In one embodiment, a plurality of second chutes 8 for the bottom ends of the deviation rectifying members to slide are formed inside the support plate 6. The second chutes 8 can limit the movement of the bottom ends of the deviation rectifying members, facilitating the improvement of the stability of the movement of the deviation rectifying members. Specifically, the deviation rectifying member includes a support rod 9 slidably installed inside the second chute 8. An active rod 10 is slidably installed up and down inside the support rod 9. The top end of the active rod 10 is connected to a deviation rectifying rod 11 that slidably penetrates the first chute 7. A spring 12 sleeved on the outer circle of the active rod 10 is installed between the bottom end of the deviation rectifying rod 11 and the top end of the support rod 9.
[0025] The driving member drives the support rod 9 to move. The support rod 9 can drive the deviation rectifying rod 11 to slide inside the first chute 7 through the active rod 10. After the top end of the deviation rectifying rod 11 contacts the pressurizing component, the deviation rectifying rod 11 drives the active rod 10 to slide up and down inside the support rod 9. The deviation rectifying rod 11 simultaneously drives the spring 12 to expand and contract. When the pressurizing component resets, the elastic force of the spring 12 can make the deviation rectifying rod 11 reset upward.
[0026] Among them, the driving member includes a push-pull rod 13 rotatably connected to one end of the support rod 9. A connecting ring 14 is rotatably connected to the outer circle of the support plate 6. A fixed block 15 hinged to the other end of the push-pull rod 13 is welded to the inner circle of the top end of the connecting ring 14. A rotating member for controlling its rotation is connected to the outer circle of the connecting ring 14. Specifically, the rotating member includes a servo motor 16 fixedly installed on the top of the equipment box 1. The output shaft of the servo motor 16 is connected to a gear 17. A toothed ring 18 meshing with the gear 17 is installed on the outer circle of the connecting ring 14.
[0027] Start the servo motor 16. The servo motor 16 drives the gear 17 to rotate. The gear 17 drives the connecting ring 14 to rotate on the outer circle of the support plate 6 through the toothed ring 18. The connecting ring 14 drives the fixed block 15 to move. The fixed block 15 drives the support rod 9 to slide inside the second chute 8 through the push-pull rod 13.
[0028] In one embodiment, specifically, the pressurizing component includes a top plate 19 connected to the top ends of the four round rods 2. A hydraulic rod 20 is provided at the center of the top plate 19. The bottom end of the hydraulic rod 20 is connected to a connecting plate 21 that can slide up and down on the surfaces of the four round rods 2. A lower pressing plate 22 is installed at the bottom of the connecting plate 21. A protective net 5 that can be sleeved on the outer circle of the detection table 4 is detachably installed on the outer circle of the lower pressing plate 22.
[0029] Start the hydraulic rod 20. The hydraulic rod 20 drives the connecting plate 21 to slide up and down on the surface of the round rod 2. The connecting plate 21 drives the lower pressing plate 22 to move. The lower pressing plate 22 can be used to press the components on the top of the detection table 4. The lower pressing plate 22 also drives the protective net 5 to move, so that when the components are detected, the protective net 5 can provide shielding protection around the components. Among them, multiple groups of connecting blocks 23 are welded to the outer ring of the top end of the protective net 5. The connecting blocks 23 and the lower pressing plate 22 are detachably connected by bolts, which is convenient for the installation, disassembly and replacement of the protective net 5.
