Multifunctional arc plate assembly machine

Abstract

The invention discloses a multifunctional assembly machine of arc plates. A driving spindle transversely arranged is mounted on a frame and is driven by a motor; the driving spindle is located below a driven spindle transversely arranged; the driven spindle is mounted below a lift slide; the upper end of the lift slide is connected with the lower end of a piston rod of a hydraulic cylinder; the lift slide can move up and down; the hydraulic cylinder is mounted on an upper support arranged at the top of the frame; two ends of the driven spindle are sleeved with positioning tubes which can axially move on the driven spindle to be positioned; the outer peripheral wall of each positioning tube is provided with a positioning ring groove; inner roll shafts located below the insides of the positioning tubes and transversely adjustable are mounted on the lift slide; outer roll shafts located below the outsides of the positioning tubes and transversely adjustable are mounted on two sides of the frame. The multifunctional assembly machine is suitable for welding and assembling arc plates and face plates, basically in a mechanical manner; welding quality and production efficiency of the arc plates and face plates are evidently improved.

Description

technical field [0001] The invention relates to an arc plate assembly device, in particular to a multifunctional arc plate assembly machine with hydraulic positioning and motor-driven movement. Background technique [0002] Arc plates are commonly used in engineering, such as for trolleys, which are also called lining trolleys, and are mainly used for concrete pouring of secondary lining (secondary lining) such as tunnels and water diversion tunnels, including walk-through and needle beam structures . The formwork of the trolley is welded by two arc plates, one panel, two head plates and several support panels. However, the most important and most important process in the welding process is the welding of the two arc plates and the panel, that is, the process of assembling the arc plates is the most important and labor-intensive. [0003] At present, the arc plate assembly of the formwork of the trolley adopts pure manual or simple tooling assembly method. The efficiency o...

However, the most important and most important process in the welding process is the welding of the two arc plates and the panel, that is, the process of assembling the arc plates is the most important and labor-intensive process.

[0003] At present, the arc plate assembly of the formwork of the trolley adopts pure manual or simple tooling assembly method. The efficiency of the pure manual method is too low and the quality is too poor, so it has been used less and less; the method of simple tooling assembly is: first use the connection Fix the two arc plates on the four columns of the tooling with bolts, and then lift the panel to coincide with the lower edges of the two arc plates at the lower ends of both sides of the panel, and then perform welding

This simple tooling and assembly method is also inefficient. Three people can assemble less than 3 arc panels in one working day, and the appearance and quality of the assembled arc panels cannot be effectively guaranteed.
