Abstract

The utility model discloses a foldable cutting compass. The foldable cutting compass is characterized by comprising two transverse rods, the tail portions of the transverse rods are hinged together, a centering cone is arranged at the front end of the first transverse rod, a shaft sleeve is connected to the front end of the second transverse rod through a connecting sleeve, a rotary shaft is arranged in the shaft sleeve, the rotating shaft is located at a needed angle through a locating pin, a cutting torch sleeve is fixed to the front end of the rotary shaft, and a guide wheel is further arranged on the second transverse rod. Standard linear workpieces, standard groove workpieces and standard round workpieces can be cut through the foldable cutting compass, and the foldable cutting compass is easy to operate, and convenient to use and carry.

Description

A kind of folding type cutting gauge

Technical field

The utility model designs a kind of folding type cutting gauge, and it is the aid cutting at surface of the work with burning torch in machine-building.

Background technology

Gas cutting metallic article becomes parts, institute's use gas cutting machine in specialization is produced, although gas cutting machine cutting efficiency is high, operation labour intensity is little, cut quality is good, but this machine is applicable to producing by batch, continuous productive process and processing in enormous quantities, because of equipment larger, cost of manufacture is higher, the mobile machined gas cutting of part is used to just inconvenience, thereby mostly be at present manual operations cutting, cutting rule is a kind of aids of cutting steel plate hand-manipulated.Existingly cut rule, its structure is, at the two ends of cross bar, be respectively equipped with centering cone and cut and chew cover, during use, the centering cone of usining is located as the center of circle, and the length of cross bar is as radius, make to cut to chew and move in a circle, thisly cut rule and only have a function, and can only, for the circle on cutting planes, for the straight line of all multi-work pieces and the cutting processing of groove, can not play booster action.

Summary of the invention

The utility model, for solving the existing single technical problem of rule purposes of cutting, provides a kind of to be easy to carry, and is convenient to cut out the straight line of standard and the folding type cutting gauge of round piece and groove.

For achieving the above object, structure of the present utility model is: a kind of folding type cutting gauge, it is characterized in that, it comprises two cross bars that afterbody is hinged, the front end of first cross bar is provided with centering cone, and the front end of second cross bar connects an axle sleeve by adapter sleeve, is provided with rotating shaft in axle sleeve, rotating shaft is positioned in the angle needing by alignment pin, and rotating shaft front end is fixed with to cut chews cover; On second cross bar, be also provided with a directive wheel.

The utility model has the advantages that 1, utilize collapsible cross bar setting, during operation, the centering cone of usining is located as the center of circle, adjust angle between two cross bars and make centering cone and cut the distance of chewing inner room and equal radius of circle, rotation is cut and is chewed chuck and rotate around the center of circle, is convenient to cut the round pieces of different sizes.2, cut and chew cover and two axle sleeves and be used in conjunction with and can realize two latitudes and rotate, be conducive to the cutting processing of groove workpiece.3, take guide support wheel as fulcrum, adjust and to cut that to chew cover consistent with rectilinear direction to be cut, be conducive to the straight cuts of workpiece.4, the utility model cuts rule by existing pull bar and improves, and can cut out straight line, groove and the round piece of standard, simple to operate, easy to use, be easy to carry.

Accompanying drawing explanation

Fig. 1 is the utility model schematic diagram:

In figure: 1a-the first cross bar, 1b-the second cross bar, 2-centering cone, 3-cuts and chews cover, 4-bolt, the horizontal axle sleeve of 5-, 6-adapter sleeve, 7-support, 8-directive wheel, 9-back shaft, 10-rotating shaft, the vertical axle sleeve of 11-.

The specific embodiment

Below in conjunction with accompanying drawing, further illustrate structure of the present utility model.

As shown in Figure 1, it comprises that two afterbodys are by the hinged cross bar of bolt 4, the front end of first cross bar 1a is provided with centering cone 2, the front end of second cross bar 1b connects a horizontal axle sleeve 5 by adapter sleeve 6, in horizontal axle sleeve 5, be provided with rotating shaft 10, rotating shaft 10 is positioned at by alignment pin in the angle needing, and rotating shaft 10 front ends are fixed with to cut chews cover 3; On second cross bar, 1b is also provided with a directive wheel 8.

The mounting structure of above-mentioned directive wheel is: on the medium position of second cross bar 1b, be provided with a vertical axle sleeve 11, vertically the bottom of axle sleeve 11 is provided with back shaft 9, and back shaft 9 lower ends are provided with support 7, and directive wheel 8 is arranged on support 7.
