Abstract
The utility model discloses a circle center positioner, particularly relates to a shaped manual positioning tool. The circle center positioner comprises a round dial (1), which is provided with a plurality of concentric circle marks (3) based on the center of the round dial (1), the marks (3) are intersected with a plurality of radial long round holes (4), a hollow control tube (5) which is perpendicular to the dial surface is arranged at the center of the dial (1), a punch (2) is mounted in the control tube (5), and can slide along the inner surface of the control tube (5), and a striker (6) is arranged at the center of the lower end of the punch (2). During use, when a circular arc on a steel plate is aimed at corresponding points on the concentric circle marks (3) on the dial (1) by means of the long round holes (4), the punch (2) can be struck, and thereby makes a central hole on the steel plate, the process is convenient and accurate, and operation is simple.
Description
Technical field
The utility model relates to a kind of machine tools field, is specifically related to a kind of manual positioning instrument of moulding.
Background technology
About existing center of circle locator, there is the circular arc of engineering design of being applicable to and teaching to ask center of circle chi at present, but its complex structure, and be not suitable for concrete workmen; The center of circle locator that also has can only be determined the position in the center of circle earlier, holes, and can not just concrete camber line make the center of circle of this camber line very easily.In a word, the center of circle tool operation process more complicated that present skilled worker uses is brought a lot of inconvenience to operating personnel.
Summary of the invention
The technical problems to be solved in the utility model is the defective that overcomes existing center of circle locator, and center of circle locator a kind of easy to use, simple to operate is provided.
In order to solve the problems of the technologies described above, the technical scheme that the utility model provides is:
Center of circle locator, a circular dial is arranged, this has a plurality of concentric circles tag lines based on its center above dial, and with above the dial along a plurality of slotted holes of radial direction, every circle tag line and a plurality of slotted hole intersect, described dial center has a hollow control valve vertical with card, a drift is housed in this control valve, drift and control valve inner surface are slidingly matched, be equipped with a striker at drift lower end centre bit, and the height of the upper surface of drift to dial bottom surface is greater than the height of control valve.
The handwheel of a radius greater than the control valve radius arranged at described drift top.
Described tag line is that the bottom is 90 ° groove, or line or indentation.
When camber line is aimed on the dial respective point in a plurality of concentric circles tag lines on the workpiece of seeing the slotted hole from dial in the concrete operations, can hit drift, drift is fallen and on workpiece, stay the indentation of striker, be the home position of being sought, the utlity model has beneficial effect:
The home position that obtains is accurate; The whole operation process is simple and efficient; For preventing to cause construction inconvenience owing to the dynamics of hitting drift is excessive, the handwheel at drift top can prevent that drift from snapping in the control valve.
Description of drawings
Fig. 1 is the cutaway view of center of circle locator front view;
Fig. 2 is the vertical view of center of circle locator.
The specific embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described.
Embodiment 1
Center of circle locator, a circular dial 1 is arranged, this has a plurality of concentric circles tag lines 3 based on its center above dial 1, this tag line 3 is 90 ° groove for the bottom, tag line 3 intersects with four slotted holes 4 along radial direction above the dial 1, described dial 1 center has a hollow control valve 5 vertical with card, a drift 2 is housed in this control valve 5, drift 2 is slidingly matched with control valve 5 inner surfaces, the handwheel 7 of a radius greater than control valve 5 radiuses arranged at described drift 2 tops, the height of the upper surface of drift 2 to dial 1 bottom surface is equipped with a striker 6 greater than the height 10-15mm of control valve 5 at drift 2 lower end centre bits.
Embodiment 2
This tag line 3 is line, and all the other features are identical with embodiment 1.
This tag line 3 is an indentation, and all the other features are identical with embodiment 1.
Claims (3)
1. center of circle locator, it is characterized in that, a circular dial (1) is arranged, a plurality of concentric circles tag lines (3) based on its center are arranged above this dial (1), this tag line (3) intersects with a plurality of slotted holes (4) along radial direction above the dial (1), described dial (1) center has a hollow control valve (5) vertical with card, a drift (2) is housed in this control valve (5), drift (2) is slidingly matched with control valve (5) inner surface, described drift (2) lower end centre bit is equipped with a striker (6), and the height of the upper surface of this drift (2) to dial (1) bottom surface is greater than the height of control valve (5).
2. the center of circle according to claim 1 locator is characterized in that, the handwheel (7) of a radius greater than control valve (5) radius arranged at described drift (2) top.
