Positioning and cutting device for fireproof door and window machining

Abstract

The invention discloses a positioning cutting device for fireproof door and window machining, and particularly relates to the technical field of door and window machining, the positioning cutting device comprises a machining platen, sliding grooves are formed in the two sides of the top of one end of the machining platen, synchronous seats are arranged in the sliding grooves, and a cutting translation motor is arranged between the two synchronous seats; a translation driving screw rod is fixedly installed at the end of an output shaft of the cutting translation motor, a fixing base is arranged at one end of the translation driving screw rod, a cutting translation base is arranged on the translation driving screw rod, and laser range finders are fixedly installed on the two sides of the top of the end, away from the sliding groove, of the cutting translation base; and a cutting lifting hydraulic cylinder is fixedly mounted at the top of the cutting translation seat. By arranging the structures such as the laser range finder, the positioning controller, the synchronous seat and the reflection seat, the automatic positioning device can automatically position, does not need manual positioning, is high in positioning precision and speed, avoids the problem of incorrect material processing size, and is relatively poor in actual use effect.
