Description

Device for disassembling ceramic bearing Technical Field The application relates to the technical field of disassembly tools, in particular to a device for disassembling a ceramic bearing. Background The bearing is an important part in modern mechanical equipment, and has the main functions of supporting a mechanical rotating body, reducing friction in the motion process of the mechanical rotating body, ensuring the rotation precision of the mechanical rotating body and being widely applied to the mechanical equipment. In the related art, a main shaft-ceramic bearing transmission structure is often applied, and an interference fit mode is used for the main shaft and the ceramic bearing, so that when the main shaft and the ceramic bearing are separated, the interference fit relation needs to be relieved. However, when dismantling the ceramic bearing that damages in the pivot, often dismantle through the method of beating, such ceramic bearing dismantles the mode, often can damage pivot and ceramic bearing at ceramic bearing dismantles the in-process, and then leads to pivot and ceramic bearing to scrap, has increased manufacturing cost. There is a need for an apparatus for ceramic bearing disassembly to address the above-described problems. Disclosure of Invention In view of the above, the present application aims to provide a device for disassembling a ceramic bearing, so as to solve the problem that the ceramic bearing and a rotating shaft are damaged when the ceramic bearing is disassembled in the related art. The device for disassembling the ceramic bearing comprises a first clamping assembly, a second clamping assembly, a displacement driving assembly and a second clamping assembly, wherein the first clamping assembly is used for clamping the ceramic bearing and can move relatively to the first clamping assembly along the axial direction of the main shaft, the second clamping assembly comprises a fixing seat, a first clamping jaw, a second clamping jaw, a first connecting rod, a second connecting rod and a driving mechanism, the first clamping jaw and the second clamping jaw are oppositely arranged, the first connecting rod and the second connecting rod are both connected with the fixing seat in a rotating mode, two ends of the first connecting rod are respectively connected with the first clamping jaw and the driving mechanism, two ends of the second connecting rod are respectively connected with the second clamping jaw and the driving mechanism, when the driving mechanism drives the first connecting rod and the second connecting rod to rotate, the first clamping jaw and the second clamping jaw are driven to move oppositely to clamp the ceramic bearing, or the first clamping jaw and the second clamping jaw are driven to move oppositely to release the ceramic bearing, clamping grooves matched with the ceramic bearing are formed in the first clamping jaw and the second clamping jaw are respectively connected with the second clamping assembly in the axial direction of the main shaft in a reciprocating mode. When the ceramic bearing is in operation, the main shaft where the ceramic bearing is positioned is clamped by the first clamping component, so that the main shaft is prevented from rotating or moving along with the ceramic bearing during disassembly. The second clamping assembly moves to the position of the ceramic bearing, the driving mechanism pushes the first connecting rod and the second connecting rod to rotate around the fixed seat and drives the first clamping jaw and the second clamping jaw to move in opposite directions, and the clamping grooves are uniformly contacted with the outer ring of the ceramic bearing, so that symmetrical clamping is realized. After clamping, the ceramic bearing is stably fixed by the second clamping assembly. Finally, the displacement driving assembly drives the second clamping assembly to drive the clamped ceramic bearing to axially move away from the first clamping assembly along the main shaft, and the main shaft cannot move together with the ceramic bearing due to the limitation of the first clamping assembly, so that the ceramic bearing can be thoroughly separated from the main shaft after the ceramic bearing rises to a certain height, and at the moment, the driving mechanism acts again to open the clamping jaw and take out the ceramic bearing, so that the whole process of separating the ceramic bearing from the main shaft can be completed. In the technical scheme, the ceramic bearing receives two symmetrical clamping forces, resultant force passes through the center of the ceramic bearing and no unbalanced load is generated, the connecting rod mechanism is purely mechanically driven, no sharp part contacts the ceramic bearing, and the risk of damage can be reduced by matching with the smooth design of the clamping groove. In some technical schemes, optionally, the driving mechanism comprises a cylinder body, a piston, a telescopic pull rod, an air source and
