Horizontal machining tool and machining method for special-shaped cabin section with non-circular section

Abstract

The horizontal machining tool comprises a front flange plate, a positioning plate, a top block, a detachable pull rod, a fixed limiting block and a rear flange plate, the front flange plate and the rear flange plate are connected through the detachable pull rod, the inner end face of the front flange plate and the inner end face of the rear flange plate are oppositely arranged, and the positioning plate is an annular plate; the positioning plate is mounted on the inner end face of the front flange plate through screws and positioning pins, a plurality of ejector blocks connected through screws are arranged on the peripheral face of the positioning plate, the extending length of the ejector blocks is adjusted by rotating the length of the screws screwed into the positioning plate, one end of a to-be-machined cabin section is positioned by the rear flange plate, and the inner wall of the other end of the to-be-machined cabin section is supported and positioned by the ejector blocks. Compared with vertical clamping, horizontal clamping of the part is more stable through the tool, machining vibration can be reduced, all machining contents can be completed through one-time horizontal clamping, and the part does not need to be turned around for secondary clamping.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing technology, and relates to a horizontal processing tool and a processing method for non-circular cross-section special-shaped cabins. Background technique [0002] The non-circular cross-section special-shaped cabin section has a non-circular cross-section, which has the characteristics of special-shaped, thin-walled, and difficult to clamp. The size of the parts is large. The maximum shape of the cross-section is 610×500, and the length is 1490. It is a multi-section tailor-welded structure. The traditional clamping method is vertical clamping, but it is difficult to achieve stable clamping when processing with this method. Improper clamping will cause a lot of processing vibration, and its supporting effect will affect the processing efficiency, clamping and deformation of parts The control brings great difficulty, limited by the Y-axis stroke of the machine tool, it is necessary t...

Problems solved by technology

[0004] The shape of the part and the structure of the end are complex, especially the irregular front end of the heading. It must be designed as an adjustable mechanism and can reliably clamp the heading front end
