Thin-walled vessel head processing and fixing device and application method thereof

Abstract

The invention provides a thin-walled vessel head processing and fixing device and an application method thereof, belongs to the field of vessel head processing in the mechanical manufacturing industry, and aims at overcoming the defect that a thin-walled vessel head is easy to deform in processing. The thin-walled vessel head processing and fixing device structurally comprises vessel head support lugs 2, hexagon socket screws 3, a slide block 4, a slide block nut 5, a slideway 6, a fixed shaft 7 and a rack nut 8, wherein holes are formed in the vessel head support lugs 2 in the axial direction; the vessel head support lugs 2 can be inserted into the slide block; matching holes are transversely formed in the vessel head support lugs 2 and the slide block 4; the slide block 4 is connected to the vessel head support lugs 2 through the hexagon socket screws 3 via the transverse matching holes; the slide block 4 can slide on the slideway 6; the fixed shaft 7 and the slideway 6 are welded into a whole; the two vessel head support lugs 2 are symmetrically welded at two sides of the outer wall edge of the thin-walled vessel head 1 in use; a screw thread at the tail part of the fixed shaft 7 is fixed on a drilling machine processing rack 9 through the rack nut 8; the hexagon socket screws are inserted into the transverse holes of the vessel head support lugs 2 and the slide block 4; and the slide block nut 5 is screwed down. The thin-walled vessel head processing and fixing device is simple in structure, convenient and fast to operate and accurate in size positioning; and the processing quality of the thin-walled vessel head is ensured.

Description

technical field [0001] The invention belongs to the field of head processing and manufacturing in machinery manufacturing industry. Background technique [0002] There are more and more thin-walled products in refining and chemical equipment, especially large-diameter thin-walled stainless steel equipment. The main difficulty in manufacturing thin-walled products is that they are prone to deformation during machining and welding, which affects the subsequent assembly and use quality of products. In general, thin-walled products are characterized by the need to assemble more joints on the head, which requires drilling more holes on the head and processing welding grooves, and the head is not fixed when drilling thin-walled heads. If it is in place or fixed unstable, there will be problems such as poor machining accuracy, eccentric drilling, and large ellipticity of the head port, resulting in more grinding and repair work, and the deformation of the head port will cause great...

Problems solved by technology

[0002] There are more and more thin-walled products in refining and chemical equipment, especially large-diameter thin-walled stainless steel equipment. The main difficulty in manufacturing thin-walled products is that they are prone to deformation during machining and welding, which affects the subsequent assembly and use quality of products.

In general, thin-walled products are characterized by the need to assemble more joints on the head, which requires drilling more holes on the head and processing welding grooves. The head is not fixed when drilling thin-walled heads. If it is in place or fixed unstable, there will be problems such as poor machining accuracy, eccentric drilling, and large ellipticity of the head port, resulting in more grinding and repair work, and the deformation of the head port will cause great difficulty in subsequent assembly.
