Punching device for air conditioner outdoor unit drain hole in assembly type building board

Abstract

The punching device comprises a frame body, a first box body is fixedly connected to the position, close to the top, of the right side of the frame body, a servo motor is fixedly connected to the right side of an inner cavity of the first box body, and a first lead screw is fixedly connected to the left end of a power output shaft of the servo motor; the left end of the first lead screw penetrates through the left side of an inner cavity of the first box body and the right side of the frame body and is inserted into the position, close to the top, of the left side of the inner cavity of the frame body, and dust and smoke generated during punching can be absorbed through mutual cooperation of a dust collection box, a driven rod, fan blades, a dust suction hood, a worm, a worm gear, a double-groove wheel, a single-groove wheel, a first belt and other mechanisms; and through mutual cooperation of a limiting box, a movable rod, an abutting plate, a spring, a second lead screw, a second internal thread block, a second sliding block, a balance abutting ring, a rolling wheel and other mechanisms, the limiting and supporting effects on the periphery of the punched hole can be achieved.

Description

technical field [0001] The invention relates to the technical field of building boards, in particular to a hole opening device for the drainage holes of an air conditioner external unit on a prefabricated building board. Background technique [0002] Prefabricated buildings refer to buildings assembled from prefabricated parts at the construction site. They are mainly divided into five types: block buildings, plate buildings, box buildings, skeleton plate buildings and ascending slab buildings. [0003] Plate refers to a flat rectangular building material plate processed into a certain size and used as a component of walls, ceilings or floors, and also refers to forged, rolled or cast metal plates. According to material categories, it includes metal plates, glass plates And wood board, etc., according to the thickness of the board, including thin board, medium board, thick board and extra-thick board. [0004] Due to the different material and thickness of the plate during ...
