Special automatic welding rotation equipment of concrete mixer chassis

Abstract

The invention discloses special automatic welding rotation equipment of a concrete mixer chassis, which comprises a workbench as well as a driving device and a driven device which are respectively arranged at two ends of the workbench, wherein the driving device is used for providing power, and the driven device is used for supporting; the driving device and the workbench as well as the driven device and the workbench are connected and fixed through connecting seats; the driving device comprises a base and also comprises a shaft seat a flange plate, a transmission shaft and a power device which are fixed on the base; the transmission shaft is arranged in the shaft seat; one end of the transmission shaft is connected with the flange plate, while the other end is connected with the power device; and the flange plate is fixedly connected with the workbench through a connecting seat. In the invention, a hydraulic system is used for providing power, and the free rotation of the mixed chassis can be realized through simple operations to obtain optimal welding angles of various welding lines. The mechanism has the advantages of compact structure, stable and reliable working state and simple operation, can improve the welding quality and the welding efficiency of the chassis and is beneficial to reducing the welding labor intensity of the mixer chassis and realizing automatic operations.

Description

technical field [0001] The invention relates to a device used in the welding process of the underframe of a concrete mixer truck to rotate the angle of the underframe so as to complete the welding operation. Background technique [0002] The concrete mixer truck is a special vehicle used to transport commercial concrete, and the underframe carrying the mixer truck tank and other accessories is one of the important parts of the mixer truck. The underframe is composed of sub-frame, front desk, backstage, tie bars, supporting components, etc. The connection is mainly a welding structure, the structure is complex, the welding volume is huge, there are many vertical welds, upward welds, welding is difficult, and the underframe The weld seam between the tie bars of the main stress-bearing parts and the longitudinal beam of the sub-frame cannot be welded during flat welding, and welding cannot be carried out under normal conditions. Many manufacturers use crane ropes for hoisting ...

AI Technical Summary

Problems solved by technology

[0003] In order to solve the problems existing in the prior art field, the welds between the underframe tie bars and the subframe cannot be welded, and most of the underframe welds are difficult to weld, the present invention provides a simple, practical, safe and reliable concrete mixer truck underframe Special equipment for automatic welding rotation, adjust the position of the welding seam of the chassis, change the angle of the welding seam, and solve the problem that the welding seam cannot be welded and the welding is difficult
