[0016] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0017] See also Figure 1-2The utility model is a hydraulic bearing inner ring parts disassembly device, comprising: a frame 1, a pressing mechanism 2 slidably arranged on the frame, a pressing piece 3 arranged below the pressing mechanism, two sets of detachable cross beams 4 arranged on the frame, and a disassembly base 5 arranged between the two sets of detachable cross beams. The disassembly base is composed of two bottom plates 51 with notches, and the two bottom plates are surrounded to form a cavity 52. ​​The bearing to be disassembled can be placed so that its outer ring parts are supported by the base and its inner ring parts are aligned with the cavity and suspended in the air. The pressing piece is driven by the pressing mechanism to push the bearing inner ring parts out of the cavity and move downward to separate from the bearing outer ring parts, so that the bearing inner ring parts fall from the cavity of the base to the bottom of the frame. The frame of this hydraulic mechanism is a fully welded I-beam main body, and the full welding is for improving the firmness and durability of the main body.

[0018] Specifically, the top pressure mechanism includes a top pressure plate 21 slidably arranged on the frame, a hydraulic jack 22 arranged on the top pressure plate, and two groups of elastic members 23 arranged between the top pressure plate and the top of the frame, wherein the elastic members are two groups of springs, the upper ends of the springs are welded to the top surface of the frame, and the lower ends of the springs are welded to the top pressure plate, which is safe and firm, and can also improve the efficiency of disassembly and assembly. The four corners of the top pressure plate are connected to the limit plate 24 by screws. The limit plate is a "mouth"-shaped structure and is mounted on the frame to keep the position from deviating when pressing down. The top pressure member is a sleeve structure and the upper end is connected to the top pressure plate. The hydraulic jack is fixed to the top pressure plate with screws to keep the descending force uniform during use. The disassembly base is composed of two bottom plates with notches. The distance between the two bottom plates is adjusted according to the size of the bearing to be disassembled, so as to adapt to products of different sizes and facilitate work.

[0019] Specifically, a number of lifting holes 6 are provided on the frame in sequence, and the disassembly beam is installed by inserting the pin into the corresponding lifting hole. The two sets of disassembly beams are connected by two sets of fastening screws 7. The disassembly beam is made of an I-shaped steel plate, which can better withstand pressure. The disassembly beam selects a suitable position through the lifting hole and the beam pin. In order to be as firm and stable as possible during the disassembly process, holes are opened at both ends of the disassembly beam and the beam fastening screws 7 are installed. When we want to disassemble, repair, and install the bearing product 8, the operator places the bearing part on the disassembly base so that its outer ring part is supported by the disassembly base and its inner ring part is aligned with the cavity. Then, the top pressure piece on the mounting frame is operated, and the hydraulic jack drives the top pressure piece of the sleeve structure to move downward, pushing the inner ring part of the bearing into the cavity until the inner ring part of the bearing breaks away from the outer ring part of the bearing and falls below the cavity, while the outer ring part remains on the disassembly base. In this way, the bearing part is disassembled, the operation is simple, and the operation efficiency is high.

[0020] The beneficial effects of the utility model are: when repairing, maintaining and upgrading machine parts, employees can remove the inner ring parts of the bearing more effectively, accurately and safely, reducing some unnecessary secondary damage, making disassembly quick and convenient, improving work efficiency, and bringing great convenience to production use.

[0021] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
