Horizontality calibration device for transverse frame of metal door frame

Abstract

The invention discloses a horizontality calibration device for a transverse frame of a metal door frame. The calibration device comprises a bottom plate, an air pipe and a pressure gauge, wherein sealing rings are arranged on vertical and horizontal sections of the bottom plate, detection blocks are fixed on the sealing rings, the detection blocks are provided with a plurality of air holes, the air pipe is divided into two channels respectively penetrating through the vertical and horizontal sections of the bottom plate to communicate with the air holes, a column and a cylinder are mounted ona horizontal section of the bottom plate, an adjustment rod is hinged at an upper section of the column, a connection rod is hinged at a middle section of the column, one end of the adjustment rod isequipped with a pressing block, the other end of the adjustment rod is hinged with a middle section of the connection rod, one end of the connection rod is equipped with a fastening block, a rubber block is arranged on an inclined surface, an outer wall of the rubber block is equipped with the pressure gauge, and an output end of the cylinder is hinged with the other end of the connection rod. Thecalibration device is advantaged in that through ameliorating existing detection equipment, rapid detection on perpendicularity of the transverse frame can be realized through simply adjusting a working state of the cylinder, and abnormal working hours in the detection process are greatly reduced.

Description

technical field [0001] The invention relates to a detection device, in particular to a levelness calibration device for a horizontal frame of a metal door frame. Background technique [0002] Casement doors and windows refer to two or more parallel or vertical points that are fixed on the sides of holes and openings, and can be opened manually, electrically, chained, twisted, rotated, or magnetically, and have certain ventilation and lighting performances. Doors and windows with locking function are divided into inward opening, outward opening, free, upper hanging, lower hanging, middle hanging, transfer, folding, lifting, etc. Swing refers to the opening form of doors and windows. Doors and windows can be made to open inside, and can also be made to open outside and inside with the function of hanging up! Swing and push-pull just refer to the opening of doors and windows, mainly through hardware to achieve the desired effect. [0003] In the processing and manufacturing p...

Problems solved by technology

And the detection mode of existing verticality of horizontal frame of casement door and window is, by using dial gauge to carry out sampling detection in many places to horizontal frame, because need extremely careful in measuring process, when the sampling error that occurs is bigger, Repeated measurements often occur, so it takes a lot of time to measure the verticality of the horizontal frame, and in order to detect problems in the production equipment in time and reduce waste products, each piece is produced and tested instead of batch Re-inspection after production, which makes the equipment idle for too long, so the production efficiency is low
