Description

Pin shaft dismounting tool

Technical Field

Background

With the development of the synthetic diamond industry, there is an increasing demand for equipment for synthesizing diamond, i.e., a hexahedral press. A cubic press typically includes a plurality of hinge beams connected by pins, such as hinge beam one and hinge Liang Er of fig. 1 and 2, that connect hinge beam one and hinge Liang Er by pin openings through which the pins pass. In the process of assembling and debugging the hexahedral press, the pin shafts between the hinge beams are often required to be repeatedly disassembled and assembled.

In the prior art, a manual operation disassembly and assembly method is mainly adopted, namely a steel bar is lifted by a plurality of operators together, one end of the steel bar is utilized to continuously strike the pin shaft, the pin shaft is struck into a pin shaft hole on the hinge beam, or the pin shaft is struck out of the pin shaft hole. However, since the hexahedral top press is a large-sized device, the weight is about 100 tons, the height is more than 4.2 meters, the weight of a pin shaft which needs to be disassembled and assembled is about 270Kg, and the pin shaft is heavier and distributed in the upper, middle and lower parts of the whole press; when the pin shafts below the pin shafts are disassembled and assembled, although operators can stand on the ground, a heavy steel bar is lifted by several persons together, the pin shafts are continuously impacted in the same pace and the same rhythm, the labor intensity is high, and the labor efficiency is low due to the fact that the physical strength is limited and the operation is very easy to fatigue; when the pin shaft is assembled and disassembled, referring to fig. 1 and 2, because the place where the upper part of the press can stand is more than 3 meters away from the ground, the space is narrow, the area for the movement of operators is smaller, and the force is applied when the pin shaft is impacted, the gravity center is easy to be unstable, the possibility of falling from a high place exists, and potential safety hazards exist.

the driving device 1 is connected with the hydraulic cylinder 3 for driving a piston cylinder 32 of the hydraulic cylinder to extend and retract in the cylinder tube 31.

In the solution of the present utility model, referring to fig. 4, the piston rod 32 is aligned with the pin 103 on the hexahedral press for connecting the hinge beams (for example, the first hinge beam 101 and the second hinge beam 102), the clamping jaws 43 of the clamp are respectively hooked at the appropriate positions on the hinge beams (for example, the clamping jaws can be respectively hooked on the outer surface of the hinge beam above the pin and the outer surface of the hinge beam below the pin), and then the clamping member 44 is fastened, so that the clamping member 44 and the hooks at the front ends of the clamping jaws clamp and fix the hinge beams (for example, the first hinge beam 101 and the second hinge beam 102). At this time, the driving device 1 is started to drive the piston rod 32 to extend out of the cylinder 31, so that the plug 321 at the front end of the piston rod pushes the pin 103, and the pin 103 is ejected out of the pin hole in the hinge beam, thereby completing the detachment of the pin 103. Therefore, the pin shaft dismounting tool provided by the utility model can be used for easily dismounting the pin shaft, operators do not need to dismount the pin shaft manually, labor force is saved, working efficiency is improved, further, a narrow space is released, and the operators do not need to excessively exert force, so that personnel falling can be avoided, and potential safety hazards are reduced.
