Abstract
The utility model relates to a circle drawing device, which provides a circle drawing tool with an unrestricted diameter to industry. The circle drawing tool is composed of a center positioner and a scribing device which can be rotated around the center positioner which comprises a magnetic base and a ruler groove block with a shaft, and the center of the magnetic base is provided with a blind hole. The scribing device comprises two rolling wheels and a pen groove, wherein, the lower end of which is provided with a ruler groove corresponding to a ruler groove of the center positioner. When the utility model is used, a scribing slate pencil is fixed by two nuts on the pen groove, a ruler strip (a steel band tape) is respectively arranged in the two corresponding ruler grooves, the scribing device is pushed to be rotated around the center positioner after the ruler strip is pulled straightly, and circle or circular arc drawing can be completed.
Description
The utility model belongs to draws sired results tool, specifically a kind of industrial major diameter round drawing device.
The workpeople in routine duties, often using plans draws the circle or the circular arc of various sizes diameter on drawing material, but the existing circle or the circular arc of planing and being only limited to minor diameter, just seem powerless more than 1 meter when diameter surpasses, particularly to run into several meters, tens meters, tens meters circle just more can make us anxious even.In this case, often can only finish by the reinforcing bar that rotates a certain size, this not only stupid but also inconvenient, particularly draw the process that the not high circle method of drawing of circle and arc size precision has seriously influenced work.
The purpose of this utility model is intended to overcome above-mentioned difficulties, and a kind of precision height is provided, and diameter is unrestricted, and industrial major diameter round drawing device easy to use is installed simply.
For achieving the above object, the utility model has adopted following technical scheme: this round drawing device comprises centralized positioning device and the scriber two parts that can rotate around it, it is characterized in that: the centralized positioning device comprises that a center has the magnetic bases of a circular blind hole, the movable chi groove that a tape spool is installed above magnetic bases; Scriber is made up of a scroll wheel and a groove, and a groove is installed in the centre of two scroll wheel connecting axles, and the used slate pencil of ruling is fixed by two nuts on the groove, this external groove bottom behind also have one with the corresponding chi groove of centralized positioning device chi groove; The centralized positioning device is with measurer such as the steel tape of scale to be connected by chi groove separately by one with scriber.
As mentioned above, the center position of industry major diameter round drawing device magnetic bases lower surface is provided with the steel point in a definite center of circle, it is characterized in that, earlier this steel point is embedded during line with in the central recess of sample under in a state of excitement, so that the centralized positioning device can be adsorbed on the center of being drawn material securely, can not arbitrarily slide.
Aforesaid industrial major diameter round drawing device, it is characterized in that described magnetic bases around be provided with four equidistant groove grooves, so that above-mentioned steel point can successfully enter with the central recess of sample under in a state of excitement, this has just avoided the drawback that the centralized positioning device is blindly looked for the center of circle.
After the center of circle is determined, earlier in the chi bar two ends difference centering locator and scriber chi groove with required size, and then the used slate pencil of will ruling is fixed by two nuts in a groove of scriber, promote scriber and rotate around the centralized positioning device under the state that the chi bar is straightened, institute draws and justifies and circular arc can be finished.
Because the chi bar can replace by means of existing measurer steel tape, again because the steel tape specification is many, and size is changeable, thereby also just successfully solved existing circle and the limited problem of arc diameter of drawing of planing, particularly industrial major diameter is drawn round problem.
Following accompanying drawing provides embodiment of the present utility model:

Below in conjunction with accompanying drawing the utility model is described further:
As shown in Figure 1, be connected by a chi bar (3) between centralized positioning device (1) and the scriber (2).Elder generation's fixed center locator (1) is fixed on chi bar zero-bit in the chi groove (4) of scriber (2) again during use, simultaneously the fixed size of the required usefulness of chi bar (3) is located in (15) of centralized positioning device (1) chi groove (16).Under the stretching situation of chi bar, promote scriber (2) and rotate around centralized positioning device (1), the circle of required diameter or circular arc can be divided into.
As shown in Figure 3, plate shaft (11) is made of the good steel of magnetic conductivity, and with the base of annular permanent magnet (12) organization center locator (1).The centre bottom of centralized positioning device (1) has one highly to be the steel point (5) of 2mm, purpose is earlier its to be embedded in when line with in the central recess of sample under in a state of excitement, its material selection magnetic material is so that centralized positioning device (1) can be adsorbed on the center of being drawn material securely, can not arbitrarily slide.
As Fig. 4 around centralized positioning device (1), have four equidistant, and the groove groove (14) vertical with the upper and lower end face of centralized positioning device (1).During use, standardized cross wire on drawing material goes out central recess in a state of excitement with sample on the crosspoint earlier, then four grooves (14) is aimed at the cross hairs of the material of drawing.At this moment, the steel point (5) of centralized positioning device (1) bottom also just naturally and understandably smoothly the central recess of insert material suffered the drawback that this has just been avoided the centralized positioning device blindly to look for the center of circle.
In plate shaft (11) center one circular blind hole is arranged as Fig. 3, in the central shaft (9) of flexible rotation is housed, this is to consider because of centralized positioning device (1) has adopted magnetic material for blind hole, and in use adsorbing some tiny iron ends has unavoidably influenced central shaft (9) to embed in the central shaft slit flexible rotation is established.Central shaft (9) is an one with chi geosynclinal block (10), and material selection brass is made.Because of brass has not magnetic conductivity,, guaranteed the flexible rotation of central shaft (9) so can not adsorbed by magnet part.One chi groove (16) is arranged on the chi geosynclinal block (10), and there is a vertical with it groove (15) its center, during use the chi bar is embedded chi groove (16), make used size aim at groove (15), and clamp nut (19) gets final product.
Shown in Fig. 1 scriber (2), it is made up of two scroll wheels (7), wheel shaft (8), chi groove (4), a groove (18), wing nut (20), (21) for another example.
As shown in Figure 7: a groove (18) is arranged on this scriber (2), and I side nation is provided with two wing nuts (20), (21), in order to clamp metal marker.A groove (18) is opened a chi groove (4) in the bottom behind as shown in Figure 5, and this chi groove (4) is the level of state perpendicular to a groove (18), is used for putting into chi bar zero-bit.Be processed with a pair of zero reference level (6) in the II of groove side nation one end bottom, require to be in together in the plane with the medial surface of a groove II side nation.During use, earlier metal marker (slate pencil) is cut the territory single-blade; When single-blade one side was close to the medial surface of a groove II side, also just nature and zero reference level (6) be on the line together a sword.When the zero-bit on the chi bar was aimed at zero reference level (6), a sword also just in time was on the zero starting point of chi bar (3), screwed nut (20), (21) get final product.
As set two scroll wheels (7) of Fig. 6 scriber (2), have only these two scroll wheels to contact with drawing material during line with a sword in the groove (18), constitute a leg-of-mutton rock-steady structure, made metal marker be difficult for rocking back and forth, thereby guaranteed the dimensional accuracy of circle and circular arc line.
