Description

Technical Field

[0001] This utility model belongs to the field of bearing disassembly technology, and in particular relates to a rapid deformation and disassembly device for deep groove ball bearings. Background Technology

[0002] Deep groove ball bearings are the most widely used type of rolling bearing, characterized by simple structure, low coefficient of friction, and high speed. They are mainly used to bear radial loads or combined radial and axial loads. Their core components include inner and outer rings, steel balls, and a cage, achieving efficient power transmission through rolling friction. "Disassembling" a deep groove ball bearing typically refers to the separation of the inner and outer rings, primarily used for maintenance, replacement, or reassembly of bearing assemblies. This requires first removing the cage (which can only be removed by removing the rivets), and then separating the inner and outer rings.

[0003] Comparing with Chinese Patent CN221018521U, a deep groove ball bearing disassembly fixture is disclosed, including a base plate and four sliding grooves. The four sliding grooves are evenly installed on the upper part of the base plate. One of the sliding grooves has a sliding disassembly structure, and the other three sliding grooves have adjusting and fixing structures. The sliding disassembly structure includes: a first slider, an operating box, a cam, an operating rod, a connecting rod, an installation sleeve, a disassembly rod, a limiting frame, an electric push rod, and a moving limiting component. The bearing is fully fixed by the cooperation of multiple fixing frames and fixing bolts. It can be adjusted and fully fixed according to different bearing specifications. Then, the rivets are removed by the cooperation of the disassembly rod and the limiting sleeve. The overall structure is simple and can be used for deep groove ball bearings with different outer diameters, showing good versatility.

[0004] However, the aforementioned patent requires operating each movement limit individually, which slows down the deformation of different deep groove ball bearings during disassembly, increases labor intensity, and reduces alignment accuracy. Therefore, a new device needs to be designed. Utility Model Content

[0005] The purpose of this invention is to provide a rapid deformation and disassembly device for deep groove ball bearings to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A rapid deformation and disassembly device for deep groove ball bearings includes a frame platform. A rivet removal assembly is mounted on the frame platform for pressing down on and removing rivets. A rotating assembly is also mounted in the middle of the frame platform for supporting the rotation of the retainer to remove rivets one by one. Clamping assemblies are mounted on both sides of the rotating assembly for clamping the outer ring of the deep groove ball bearing from both sides for centering. A drive assembly for providing clamping force is mounted below the clamping assembly. The rivet removal assembly includes a cantilever frame. A telescopic cylinder is mounted on the top of the cantilever frame, and a disassembly head is mounted on the telescopic end of the bottom of the telescopic cylinder. An adjustment mechanism for sliding and adjusting the removed rivets is mounted at the bottom of the cantilever frame. The rotating assembly includes a first motor fixedly mounted on the bottom surface of the frame platform. A drive shaft is mounted on the output end of the first motor, and the drive shaft passes vertically upward through the frame platform and is keyed to a support mechanism. The clamping assembly includes two symmetrically arranged clamping blocks, with V-grooves formed on the opposite surfaces of the two clamping blocks.

[0008] Furthermore: the supporting mechanism includes a supporting platform, a plurality of limiting sleeves are evenly distributed around the circumference of the supporting platform, a connecting sleeve is provided in the middle of the bottom of the supporting platform, and a first locking pin is installed on the side of the connecting sleeve.

[0009] Furthermore: the limiting sleeve penetrates the support platform, and the support platform is disc-shaped.

[0010] Furthermore: the drive assembly includes two limiting slide grooves symmetrically arranged on the frame platform, two support seats symmetrically arranged below the frame platform, a positive and negative threaded screw is installed between the two support seats, a second motor is provided at one end of the positive and negative threaded screw, and two threaded sliders are symmetrically installed on the positive and negative threaded screw.

[0011] Furthermore: the threaded sleeve slider is provided with a connector, the connector is inserted into the bottom of the clamping block and fixed by the second locking pin on the outside of the clamping block, and the threaded sleeve slider slides along the limiting groove.

[0012] Furthermore, the surface of the clamping block is provided with anti-slip texture.

[0013] Furthermore: the adjustment mechanism includes a limiting slider fixedly installed at the bottom of the cantilever frame and a limiting slide rail fixed on the machine frame platform. The limiting slider slides along the limiting slide rail, and a third locking pin is provided on the side of the limiting slide rail.

[0014] Compared with existing technologies, the beneficial effects are:

[0015] Modular design (such as replaceable support platform and adjustable cantilever frame) supports rapid deformation adaptation for different bearing models. Various sizes can be accommodated by changing the support platform and adjusting the disassembly head position, saving time and effort. The V-groove clamping block and anti-slip texture design, combined with a symmetrical clamping mechanism driven by positive and negative threaded screws, ensures precise alignment and secure fixation of the bearing outer ring, preventing damage or errors caused by slippage or offset during disassembly. The matching design of the limiting sleeve and support platform ensures precise positioning of each rivet, with perpendicular force direction during clamping, reducing the risk of off-center loading. The integrated rotating component (first motor drives the support platform to rotate at indexes) and rivet removal component (cylinder automatically presses down) enable continuous automated rivet removal, eliminating the need for repeated manual adjustment of bearing positions and significantly reducing single-operation time, especially suitable for batch processing of bearings with multiple rivets. This achieves efficient, precise, and safe removal of deep groove ball bearing rivets, with significant application value in maintenance, testing, and other fields. Attached Figure Description
