Assembling tool for assembling pump valve bearing and working method thereof

Abstract

The invention discloses an assembling tool for assembling a pump valve bearing and a working method thereof. A pressing ring is fixedly arranged at the bottom end of a piston rod, when a clamping mechanism clamps the bearing to be assembled on a pump valve fixed on a support table, a hydraulic cylinder pushes the piston rod to move downwards, so that the piston rod drives a movable plate to move downwards, the pressing ring presses the bearing to be assembled downwards into the pump valve, and the bearing is clamped to the upper end of the pump valve before being assembled. Furthermore, in theprocess of pressing the bearing into the pump valve by the pressing ring, no extra clamp is arranged on the bearing, so that the bearing to be assembled cannot generate axial force with the pump valve in the downwards pressing process of the pressing ring, after the bearing is pushed into the pump valve by the pressing ring to complete assembly, the bearing cannot have staggered force with the pump valve, the assembly efficiency of the pump valve is greatly improved, the operation safety of the bearing after assembly is improved, and the service life of the pump valve is prolonged.

Description

technical field [0001] The invention relates to the field of assembly tooling, in particular to an assembly tooling used for pump valve bearing assembly and a working method thereof, belonging to the technical field of assembly tooling application for pump valve bearing assembly. Background technique [0002] Pump valve is a general term for pumps and valves. The reason why pumps and valves are often linked is the use of occasions. That is to say, where there are pumps, there are generally valves, and some places often require pumps, and they are all used for liquid transportation. When the pump valve is in use, it needs to use the bearing for power transmission. The bearing assembly quality of the pump valve is one of the important factors affecting the use of the pump valve. The existing pump valve bearing assembly mostly adopts the horizontal assembly, that is, by assembling the pump valve to be installed. The shaft to be assembled is positioned at the station by the ass...

AI Technical Summary

Problems solved by technology

[0003] The object of the present invention is to provide an assembly tool for pump valve bearing assembly and its working method, to solve the problem that the existing pump valve bearing assembly mostly adopts horizontal assembly, that is, by passing the assembly shaft of the pump valve to be installed The tooling is positioned on the station, and the bearing is pushed horizontally into the position of the pump valve to be assembled through the material return mechanism. When the bearing is in contact with the pump valve, the force is uneven, causing the bearing to generate axial force with the pump valve after assembly, which in turn affects the normal operation of the pump valve; and the existing bearing assembly tooling cannot meet the requirements of the bearing and bearing seal. Continuous installation, so that the bearing needs to be assembled with bearing seal after assembly, which greatly reduces the technical problem of bearing assembly efficiency
