Abstract
The utility model belongs to a tool for cutting a circular plate or a circular hole on a steel plate by means of a cutting torch in factory or construction sites, particularly relating to a tool for cutting circles on the steel plate. The tool consists of a positioning cone and a scale rod which is matched with the positioning cone; the positioning cone has a structure that the lower part of a cylindrical base body is connected with a cone tip; the base body is provided with a guide hole vertical to the axis of the base body; the cylindrical surface of the base body is provided with an axle hole which is vertical to the guide hole and is communicated with the guide hole; the surface of the scale rod of which one end is provided with a positioning sleeve is provided with scales; the cylinder of a cutting torch nozzle is movably matched with the positioning sleeve; the scale rod is movably matched with the guide hole of the positioning cone; and the scale rod is positioned by means of a positioning shaft bolt arranged in the axis hole. The tool has the advantages of reasonable structure, convenience for operation, high precision of cutting the circular plate or the circular hole on the steel plate, high flatness of cut surfaces, convenience for determination of cutting sizes, small volume and convenience for carrying.
Description
Technical field
the utility model belongs to factory or job site and uses cutting torch on steel plate, cut the instrument of plectane or circular hole, particularly a kind of instrument that cutting is justified on steel plate.
Background technology
use cutting torch on steel plate, to cut plectane or circular hole in factory or job site, and traditional method is to utilize compasses on steel plate, to draw to need the circle of cutting, and the hand-held cutting torch of operative employee cuts according to the circular lines of drawing then.Its weak point is that the precision of hand cut plectane or circular hole is low, and the flatness of cut surface is low, and inconvenient operation, will utilize Steel Ruler to confirm the radius of compasses at the steel plate upper drawing circle earlier, uses the compasses of confirming good radius at the steel plate upper drawing circle again.
Summary of the invention
The purpose of
the utility model is to provide a kind of instrument that on steel plate, cuts circle, and it is rational in infrastructure, and is easy to operate; The precision of cutting plectane or circular hole is high on steel plate, and the flatness of cut surface is high, and definite cut lengths are very convenient; Volume is little, is easy to carry.
The purpose of
the utility model is achieved in that a kind of instrument that on steel plate, cuts circle; Be made up of locating cone and the scale bar that matches with locating cone, the structure of locating cone is that the bottom of cylindric matrix is connecting the awl point, on matrix, is being provided with and the perpendicular pilot hole of matrix axis; On the matrix face of cylinder, be provided with perpendicular with pilot hole; And its chi face of scale bar that the axis hole that is communicated with pilot hole, an end are provided with locating sleeve is provided with scale, and the cylinder of nozzle of cutting torch and locating sleeve are movingly; The pilot hole of scale bar and locating cone makes the scale bar location through the locating shaft bolt of installing in the axis hole movingly.
When
the utility model uses, confirm the radius of required plectane between locating cone to the locating sleeve or circular hole, tighten bolt then scale bar and locating cone are located each other through regulating scale bar.Use weight to knock locating cone and locate, regulate cutting torch flame being applicable to cutting, cutting torch is packed in the cutting torch locating sleeve, pin the locating cone of the utility model on the other hand, use cutting torch cutting on the other hand at circle centre position.
The use of the utility model has the following advantages:
1, volume is little, is easy to carry;
2, the precision of cutting plectane or circular hole is higher than hand cut;
3, the flatness of cut surface is higher than hand cut;
4, the scale bar that carries scale can directly be used for confirming size.
the utility model is rational in infrastructure, easy to operate, and the precision of cutting plectane or circular hole is high on steel plate, and the flatness of cut surface is high, and definite cut lengths are very convenient, and volume is little, is easy to carry.
Description of drawings
To combine accompanying drawing that the utility model is done further to describe below,
Fig. 1 is the utility model cuts circle on steel plate a main TV structure sketch map;
Fig. 2 removes the plan structure sketch map of cutting torch for Fig. 1.
The specific embodiment
a kind of on steel plate instrument of cutting circle, like Fig. 1, shown in Figure 2, form by locating cone 2 and the scale bar 1 that matches with locating cone 2; The structure of locating cone 2 is that the bottom of cylindric matrix is connecting the awl point; On matrix, be provided with and the perpendicular pilot hole of matrix axis, on the matrix face of cylinder, be provided with pilot hole perpendicular, and the axis hole that is communicated with pilot hole; Scale bar 1 its chi face that one end is provided with locating sleeve 5 is provided with scale; The cylinder of cutting torch 4 nozzles and locating sleeve 5 movingly, the pilot hole of scale bar 1 and locating cone 2 makes scale bar 1 location through the locating shaft bolt of installing in the axis hole 3 movingly.The locating cone 2 of the utility model is positioned on the center of circle of steel plate 7 circle of contacts, and the below of cutting torch 4 is the cutting seam 6 on the steel plate 7.
