Description

Stirring shaft assembling device Technical Field The application relates to the technical field of stirring shaft assembly, in particular to a stirring shaft assembly device. Background The mortar truck is a vehicle for transporting and stirring ready-mixed mortar, and the mortar in the tank body needs to be continuously stirred in the transportation process to prevent the mortar from solidifying. The tank body of the mortar vehicle is provided with a front end plate and a rear end plate, and through holes for installing the stirring shaft are formed in the front end plate and the rear end plate. When the stirring shaft is installed, the shaft end flange is required to be connected with the through holes on the front end plate and the rear end plate in an aligned mode. However, the through-hole apertures in the front and rear end plates are typically large, resulting in difficult alignment of the flange bolt holes with the center of the can through-holes. In the installation process, if the flange is not concentric with the through hole of the tank body, the stirring shaft can be inclined. After the stirring shaft is inclined, friction or clamping stagnation can occur between the stirring shaft and the inner wall of the through hole of the tank body during rotation, and normal operation is affected. At this time, the stirring shaft is required to be detached, the centering is readjusted, and the operation of the process is time-consuming and labor-consuming. Therefore, how to ensure the alignment degree of the flange and the through hole of the tank body while simplifying the installation operation has become a technical problem to be solved. Disclosure of Invention The embodiment of the application provides a stirring shaft assembly device which can simplify the installation operation and ensure the alignment degree of a flange and a through hole of a tank body.
