Clamping device and cutting method for half-side pipe laser cutting

Abstract

The invention provides a clamping device for half-side pipe laser cutting. The clamping device for half-side pipe laser cutting comprises a fixing plate, and a positioning plate, a stop block and a pressing and blocking mechanism which are arranged on the fixing plate, the positioning plate is an arc-shaped plate matched with the diameter of an inner hole of a half-side pipe to be cut, and the half-side pipe to be cut is arranged outside the positioning plate in a covering manner during assembly; and the stop block is arranged at one end of the positioning plate and used for stopping the end wall of an assembled half-side pipe. The pressing and blocking mechanism is arranged on the radial outer side of the positioning plate, a pressing block capable of stretching out and drawing back in the radial direction relative to the assembled half-side pipe is arranged on the pressing and blocking mechanism, and the pressing block is used for pressing the flange edge on the radial outer side of a half-side pipe when stretching out. An arc-shaped positioning plate is arranged to support the interior of the half-side pipe to be cut, and the exterior of the half-side pipe is pressed and limited through the pressing and blocking mechanism and the stop block. According to the clamping device for half-side pipe laser cutting, the structure is simple and reasonable, disassembling and assembling are convenient, the positioning plate is in linear contact with the half-side pipe to be cut, molten slag can be blown away conveniently, cutting quality is guaranteed, positioning is firm, and universality is high.

Description

technical field [0001] The invention belongs to the technical field of positioning devices, and in particular relates to a clamping device and a cutting method for laser cutting of half pipes. Background technique [0002] Laser cutting is an efficient and flexible processing method for removing material allowance, and it is widely used in aerospace sheet metal parts. Taking the stainless steel half pipe as an example, traditional processing adopts wire cutting or manual cutting, which is slow in processing speed and takes up a lot of resources, while laser cutting is fast in processing speed and saves costs. During laser processing, sheet metal parts need to be positioned to ensure cutting accuracy. The positioning tooling usually used in positioning cannot meet the characteristics of small batches and many specifications of aerospace sheet metal parts. Taking the half pipe as an example, there are only dozens or hundreds of pieces in a production batch, and the cost of u...
