H-shaped beam fitting up device and fitting up method

Abstract

The invention discloses an H-shaped beam fitting up device and a fitting up method. The body of the device comprises a work bench; both sides of one end of the work bench are respectively provided with a support; the upper part of the support is connected with a pin shaft in a penetrating way; the pin shaft is pivoted with a bearing which is fixedly connected with a round tube; the end part of the round tube is connected with two positioning plates arranged in parallel and provided with laser openings by an end plate; the upper part of the end plate is articulated with one end of an actuating arm; and the other end of the actuating arm is connected with a threaded rod provided with a hand wheel on the top part in a penetrating way. When fitting up, a rib plate is vertically inserted into the laser opening of the positioning plate, and an H-shaped steel is levelly laid on the rid plate, the actuating arm is erected straightly, the H-shaped steel is tightly compressed and fixed by screwing off the threaded rod by screwing the hand wheel; and finally, point welding is completed by converting the device by screwing a handle. The invention can better ensure product accuracy, meanwhile, is convenient for workers to carry out fitting up and welding, thereby improving the working efficiency and providing strong guarantee for enterprises to carry out volume production of H-shaped beams with different types and line production.

Description

technical field [0001] The present invention relates to a pairing device and method for H-shaped beams, in particular to a pairing device and method for spot-welding H-shaped steel and ribs when making H-shaped beams. Background technique [0002] In recent years, as my country's steel production has increased year by year, the related manufacturing industries of steel structures have also become increasingly prosperous. In the process of processing steel structures, ribs are often welded on H-shaped steel webs to form H-shaped beams as required. At present, when assembling various forms of H-shaped beams, it is generally used to make different simple tools to fix the ribs and the middle partition. Such a simple assembly of H-beams is not only a waste of manpower, material resources and working time, it is also not conducive to ensuring the dimensional accuracy and vertical accuracy of the H-beam ribs during butt welding, and it is often easy to install wrong sizes.

Problems solved by technology

Such a simple assembly of H-beams is not only a waste of manpower, material resources and working time, but also not conducive to ensuring the dimensional accuracy and vertical accuracy of the H-beam ribs during butt welding, and it is often easy to install the wrong size

Especially when carrying out mass production, the above-mentioned methods reflect many problems such as wasting raw materials, consuming manpower and material resources, not being able to guarantee the production accuracy, and having hidden dangers of accidents.
