Embodiment Construction

[0014] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0015] The manufacturing process of the beam member to be processed is divided into two separate processes: the beam body manufacturing and the connecting seat manufacturing. The beam body 4 is manufactured according to the general production method, and the connecting seat 3 is manufactured on conventional equipment; the combination platform is the benchmark when combining various components on site platform.

[0016] like figure 1 , the processing method of the large-scale cross-beam member with connecting seat of the present invention relies on the special tooling structure, including two tooling supports 1 arranged on the combined platform, and each tooling support 1 is provided with two upwards Tooling cover 2 and a support frame 5. The two tooling sleeves 2 on each side of the tooling support 1 are used for hinged connection with the tw...

Abstract

The invention discloses a method for processing a large beam member with connecting seats, which comprises the following steps of: firstly, determining the axis distance A between two tool sleeves on a tool support on each side, the height B between a central line of a beam body and the centers of lug holes of the connecting seats, the horizontal positioning size C of the central line of the beambody, and the size D of an opening between two connecting seats according to the product sizes of the beam body and the connecting seats; secondly, arranging two tool supports on a combined platform according to size data determined in the previous step, arranging the tool sleeves and support frames, hinging the two tool sleeves of the tool support on each side with two lugs of one connecting seat, and arranging the beam body on the two support frames; and finally, assembling and welding the beam body and the connecting seats to finish the processing of the large beam member with the connecting seats. By the method, the problems that the connecting seats of the large beam member with the connecting seats have a long hole distance, are needed to be coaxial, and are difficultly processed bygeneral equipment are solved.

Description

technical field [0001] The invention belongs to the technical field of manufacturing structural parts, and relates to a processing method of a large-scale cross-beam member with a connecting seat. Background technique [0002] The processing of large-scale beams with connecting seats has always been a technical problem in the production of structural parts, especially large-scale components of oil drilling equipment are common. The girder beam is a key component in the derrick of an oil drilling rig, and plays a vital role in the working process of the drilling rig. Due to the particularity of this type of large beam structure, the overall processing method cannot be used to ensure the shape, position and size requirements of each group of holes, and the manufacturing accuracy is only medium and low. How to effectively realize the manufacture of similar large-scale hole-group components has become an urgent problem to be solved in production. SUMMARY OF THE INVENTION [...
