A water pump impeller press-fitting device and press-fitting method thereof

Abstract

The invention discloses a water pump impeller press-fit device and a press-fit method thereof. The water pump impeller press-fit device comprises a worktable, an operation panel, a locating bar, a rotary bar, a horizontal shaft sleeve, a support, a guide device and a press-fit machine. The press-fit method comprises the following steps: S1, fixing a pump body onto the operation panel, and determining a position of the locating bar; S2, placing an impeller on a pressing head, mounting the guide device, and clamping the impeller by means of the guide device; and S3, starting a motor to start forpress-fit operation, driving the impeller to move toward a pump shaft through the pressing head, setting a movement direction through the guide device till the impeller is divorced from the guide device, and mounting the impeller on the pump shaft in a press-fit manner to finish the press-fit operation. According to the water pump impeller press-fit device and the press-fit method thereof, the impeller can be stably mounted on the pump shaft in a press-fit manner, the acting direction is set, the press-fit operation is simple, and a lubricant can improve the press-fit efficiency and protect the impeller and the pump shaft.

Description

technical field [0001] The invention relates to the technical field of water pump processing, in particular to a water pump impeller press-fitting device and a press-fitting method thereof. Background technique [0002] A pump is a device used to move a liquid, gas or special fluid medium, that is, a machine that does work on a fluid, and a water pump is one of the most commonly used pumps in our daily life. In the production process of the water pump, there will be multiple processing procedures, among which the impeller press-fitting is generally used as the last processing procedure in the water pump assembly. Compared with other components, the impeller is small in size, and its installation method is usually to put the component on the workbench first, put the impeller on the pressure head, and the pressure head contacts the impeller and presses down into the pump shaft, but in the actual operation process , In the process of pressing down the impeller, there is often ...
