Detailed Description
In order to clearly illustrate the technical features of the present invention, the present invention is explained in detail by the following embodiments in combination with the accompanying drawings. It should be noted that the components illustrated in the figures are not necessarily drawn to scale. Descriptions of well-known components and techniques are omitted so as to not unnecessarily limit the invention.
As shown in fig. 1 and 2, a bearing disassembling tool for disassembling and assembling a bearing in a pipe cavity workpiece comprises a clamping mechanism, a connecting rod mechanism and a force application mechanism; the jaw mechanism is hinged at the front end of the connecting rod mechanism and is used for pushing and pulling the bearing; the force applying mechanism can be sleeved on the connecting rod mechanism in a back-and-forth movement mode and is used for intermittently applying pushing force or pulling force to the jaw mechanism.
The connecting rod mechanism comprises a connecting rod 1, a hinged frame 2 and a handle, the handle is connected to the rear end of the connecting rod 1, and the hinged frame 2 is fixedly connected to the front end of the connecting rod 1. The hinge frame 2 comprises a hinge upper plate, a hinge lower plate and a rear end plate, the rear end plate is fixedly connected with the front end of the connecting rod 1, and the hinge upper plate and the hinge lower plate are respectively arranged at the upper side and the lower side of the rear end plate. The clamp mechanism comprises a left clamp 3, a right clamp 4, a reset spring 5, a jacking screw 6 and a jacking rotating frame 7. The middle parts of the left clamp 3 and the right clamp 4 are hinged in a crossing way, and the hinged parts are hinged with the hinged frame 2. And the outer sides of the front ends of the left forceps holder 3 and the right forceps holder 4 are respectively provided with a push-pull block 12 which is used for applying force to the bearing in the process of dismounting the bearing. A transversely through jacking screw hole is formed in the right forceps holder 4, and a jacking positioning groove is correspondingly formed in the inner side of the left forceps holder 3; the jacking screw 6 is in threaded connection with the jacking screw hole, the inner end of the jacking screw 6 corresponds to the jacking positioning groove, and the jacking rotating frame 7 is installed at the outer end of the jacking screw 6. The return spring 5 is installed between the rear ends of the left jaw 3 and the right jaw 4, and when the return spring 5 is in a return condition, an opening between the front ends of the left jaw 3 and the right jaw 4 is relatively narrow. The front part of the connecting rod 1 is provided with a front force application plate 8, the rear part of the connecting rod is provided with a rear force application plate 9, and the force application mechanism comprises a force application sleeve 10 and a force application rod 11; the force application sleeve 10 can be sleeved on the connecting rod part between the front force application plate 8 and the rear force application plate 9 in a back-and-forth movement mode, and the force application rod 11 is fixedly installed on the outer side of the force application sleeve 10.
