Abstract
The invention relates to a cantilever type circular arc marking device. A vertical rotating shaft is fixedly arranged on a base, and is provided with threads; an auxiliary cantilever beam, a gasket, a main cantilever beam and an adjusting nut are orderly mounted on the rotating shaft from top to bottom; the main cantilever beam and the auxiliary cantilever beam both are capable of swinging relatively to the rotating shaft; and main and auxiliary pointers are respectively and slidingly sleeved to the main cantilever beam and the auxiliary cantilever beam. The cantilever type circular arc marking device is simple in structure, easy to process and fabricate, low in cost and convenient to use.
Description
Technical field
The present invention relates to a kind of circular arc chalker, be particularly suitable for the line of lattice plate opening.
Background technology
Take with drawings print machine by the circle that prints respective diameters at 1: 1 for the production of band circular hole lattice plates (especially more than the diameter 1000mm) more in industry field at present, get off to give the workshop workman with circular arc cutting from the drawing more afterwards, the workman is put into lattice plate relevant position according to the location dimension at circular arc place on the lattice plate with pattern, the relative position of arc-shaped edges dative plate of then prolonging pattern with marking pen makes marks, cut at institute's gauge point afterwards, finally make the required grille-like with circular arc of user.The drawback of this kind production technology is: one owing to there not being at present special circular arc printer, used printer is the printer machine, even drew by 1: 1, the circular arc figure that prints also has error and along with circular diameter increases and increases (when printing diameter 1500mm circular arc time error just more than 6mm).Two because printing paper width 600mm only, surpasses 600mm radius bowlder and can only divide two parts to print and then stick up with glue when printing, and the pattern after sticking up is put a little while will be wrinkling, has a strong impact on the precision of circular arc, and grid easily produces quality accident.Three is more to the line cutting action from making pattern because the paper model is easily damaged aborning, has a strong impact on production efficient, increased quality risk.Four special-purpose drawing paper costs are very high because the paper very irregular after the circular arc cutting and produce used circular arc pattern and be finished after all breakage can only all sell as waste paper, cause the wasting of resources, production cost increases.
Summary of the invention
In order to overcome the shortcoming of prior art, the invention provides a kind of cantilevered circular arc chalker, it is simple in structure, easy processing and fabricating, cost is low, and is easy to use.
The present invention solves the technical scheme that its technical problem takes: fix vertical rotating shaft on the base, screw thread is arranged in the rotating shaft, auxiliary cantilever beam, packing ring, main boom beam and adjusting nut are housed in the rotating shaft from top to bottom successively, main boom beam and auxiliary cantilever beam can relative shaft swings, on main boom beam and the auxiliary cantilever beam respectively slidably cover main and auxiliary pointer is arranged.
The present invention is simple in structure, easy processing and fabricating, and cost is low, and is easy to use.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is front view of the present invention;
Fig. 2 is top view of the present invention;
Fig. 3 is that the present invention uses state reference map.
The specific embodiment
As shown in drawings, fix vertical rotating shaft 8 on the base 7, in the rotating shaft 8 screw thread is arranged, auxiliary cantilever beam 6, packing ring 10, main boom beam 1 and adjusting nut 9 are housed in the rotating shaft 8 from top to bottom successively, mutually countershaft 8 swings of main boom beam 1 and auxiliary cantilever beam 6, overlapping slidably respectively on main boom beam 1 and the auxiliary cantilever beam 6 has main and auxiliary pointer 2,5.
The lower end of described owner pointer 2 is marking pen 4 fixedly.
Difference fixing and locking device on the described main and auxiliary pointer 2,5 is in order to lock main and auxiliary pointer 2,5 respectively and between main boom beam 1 and the auxiliary cantilever beam 6.
On the described main boom beam 1 scale is arranged.
During use, that base 7 of the present invention is fixing with the basis, ground.At first mark starting point and the terminal point of the circular arc of opening at the rectangular grid plate of lattice plate 11, by the mobile main and auxiliary pointer 2,5 of the radius size (will increase the thickness of a bound edge band steel) of opening circular arc to the relevant position, rear locking.Make main and auxiliary pointer 2,5 corresponding on the starting point and terminal point of the arc opening of opening that marks respectively by mobile lattice plate 11, the axle center of rotating shaft 8 this moment namely is the center of circle of the arc opening of opening on the lattice plate 11.Remove auxiliary boom beam 6, rotation main boom beam 1, the arc track that marking pen 4 is drawn is exactly the track of lattice plate 11 round mouth of opening, for follow-up cutting provides accurately line of cut.
By regulating adjusting bolt 9 main and auxiliary cantilever beam 1,6 is moved up and down, and then can adapt with the lattice plate 11 of differing heights.
