Problems solved by technology

The problem existing in the existing magnetic ground gauge is that since the circular sheet to be cut is cut with the magnetic base as the center of the circle, every time a circular sheet is cut and the next circular sheet is cut, the magnetic The seat is removed and moved to the center of another plate to be cut, so that the cutting of circular plates cannot be carried out continuously, resulting in low cutting efficiency

Embodiment Construction

[0016] The implementation of land regulations such as figure 1 Shown: include magnetic base 1, magnetic base 1 includes the magnet installation groove that its lower end offers and the magnet 1-1 that is installed in the magnet installation groove. The magnetic base 1 is rotatably equipped with a vertical column 3 whose axis of rotation extends vertically, and the magnetic base 1 is threaded with a column locking screw 2 for locking and fixing the vertical column 3 . The upper end of the vertical column 3 is slidingly inserted with a transverse cantilever 5, and the insertion direction of the transverse cantilever 5 is consistent with the radial extension direction of the rotating shaft of the vertical column 3. Tighten the fixed cantilever locking screw 4. The end of the horizontal cantilever 5 away from the magnetic base 1 is rotatably equipped with a center positioning structure 6 whose axis of rotation extends vertically. The centering cone 6-1 below the rotating connect...

Abstract

The invention relates to ground compasses, which comprise a magnetic base and a compass arm with a vertically extending rotary shaft. A transverse suspension arm is connected onto the magnetic base, the extending direction of the transverse suspension arm is consistent with the radial direction of the rotary shaft of the compass arm, the compass arm is rotatably assembled at one end of the transverse suspension arm far away from the magnetic base, and a gap for making way for the magnetic base when the compass arm vertically rotates is reserved between each of two ends of the compass arm and the magnetic base. The magnetic base is not positioned on a to-be-cut plate by the aid of the transverse suspension arm, so that a next plate can be cut without detaching the magnetic base from the cut plate, operation is simple and convenient, and cutting efficiency is high.

Description

technical field [0001] The invention relates to a ground gauge used for mechanical fitters and gas cutters. Background technique [0002] Before processing circular sheet metal, it is necessary to draw a circle on the steel plate with a compass to determine the cutting trajectory, and then use gas cutting to carry out the cutting operation. Due to the different proficiency of workers in gas cutting, the processing accuracy of the steel plate is also different. Especially when the operation is unskilled, the outer edge of the cut steel plate has a large roughness, and secondary processing is required. Sometimes the size of the cut steel plate is seriously smaller than required. The size not only causes material waste, but also increases the workload. [0003] For this reason, Chinese patent CN2747029Y discloses a kind of "magnetic ground gauge", which includes a magnetic base and a rotating gauge head that is rotatably assembled on the magnetic base. Gas cutting torch head ...
