Chamfering device used for vehicle-mounted navigation display screen

Abstract

The invention discloses a chamfering device used for a vehicle-mounted navigation display screen. The chamfering device comprises a chamfering device framework; a display screen limiting cabin is arranged in the chamfering device framework; the bottom part of the display screen limiting cabin is provided with a display screen holding plate; a display screen limiting pad is laid on the upper surface of the display screen holding plate; an L-shaped limiting bar is arranged above the display screen limiting cabin; a limiting lead screw is connected above the L-shaped limiting bar; the limiting lead screw penetrates through the top part of the chamfering device framework and is connected with a connecting loop bar; one side of the connecting loop bar is connected with a limiting handle; and alimiting bar fixing rotary knob is arranged at a position, located at the outer side of the limiting lead screw, on the junction of the limiting lead screw and the top part of the chamfering device framework. The chamfering device disclosed by the invention has the beneficial effects of being compact in structure, simple to operate, and convenient to use; the problem that a display screen cannot be limited when being chamfered in the prior art is solved; meanwhile, the chamfering device can automatically reset after chamfering operation, so that both time and labor are saved, the display screen can be conveniently taken out, and defects in the prior art are solved.

Description

technical field [0001] The invention particularly relates to a chamfering device for a vehicle navigation display screen, which belongs to the technical field of mechanical equipment. Background technique [0002] Chamfering is the process of processing the right-angled sides of parts or objects for easy splicing and storage. Traditional large-scale chamfering machines are time-consuming and labor-intensive, and are not suitable for chamfering processing of small car navigation display screens. Hand-held chamfering machines cannot Limiting the position of the car navigation display is difficult to operate and has a low fault tolerance rate, and the processing time is long, so it is not suitable for chamfering of the car navigation display. Contents of the invention [0003] The object of the present invention is to overcome the defects of the prior art and provide a chamfering device for a car navigation display screen. [0004] The technical solution for achieving the ab...
