Specific embodiment
It is described in detail below in conjunction with embodiment of the attached drawing to technical solutions of the utility model.Following embodiment is only
For clearly illustrating the technical solution of the utility model, therefore it is only used as example, and it is originally practical to cannot be used as a limitation limitation
Novel protection scope.
As shown in Figure 1, Figure 2 and Figure 3, the circle of contact device locator of the present embodiment, including determine made of transparent acrylic material
Position plate 1 has been arranged concentrically several setting circles 11 on the positioning plate 1, and the side of the positioning plate 1 is provided with L-shaped first positioning
The contour convergence of the second positioning surface 21 on face 12, first positioning surface 12 and circle of contact device 2, specifically, the first positioning surface 12
Profile only be overlapped with the partial contour of the second positioning surface 21；The circle of contact device locator of the present embodiment further includes fixed plate 3, this is solid
The side of fixed board 3 is formed with L-shaped confined planes 31, which can be fitted tightly on first positioning surface 12 and second
On positioning surface 21；Wherein, make fixed plate 3 and positioning plate 1 in horizontal plane after the confined planes 31 and the fitting of the first positioning surface 12
It is interior that there is unique relative positional relationship, and after the second positioning surface 21 and the fitting of confined planes 31 circle of contact device 2 and fixed plate 3 are existed
There is unique relative positional relationship in horizontal plane；Also, the setting circle 11 after confined planes 31 and the fitting of the first positioning surface 12
The circle of contact center location of center location, the circle of contact device 2 after being bonded with the second positioning surface 21 and confined planes 31 is overlapped.
When in use, circular center location to be cut is found accurately first with the setting circle 11 on positioning plate 1, then will fix
The confined planes 31 of plate 3 are fitted on the first positioning surface 11 of positioning plate 1, so that the relative position of the two in the horizontal plane is unique,
Then positioning plate 1 is removed, the position for being kept fixed plate 3 is constant, the second positioning surface 21 of circle of contact device 2 is bonded with confined planes 31,
So that circle of contact device 2 and the relative positional relationship of fixed plate 1 in the horizontal plane are unique, at this point, the circle of contact center of circle of circle of contact device 2
Position is overlapped with the center of circle of the setting circle 11 of positioning plate 1 just, i.e., is overlapped, is then adjusting with circular center location to be cut
The circle of contact can be easily realized after the radius of circle of contact device 2；When needing to cut annulus, it is only necessary to maintain fixed plate in cutting process
3 position is constant, and the radius by adjusting circle of contact device 2 twice can be cut into concentric loop to fast and high quality.
It should be noted that the positioning plate 1 of the present embodiment is not accurately to find, that is, is not necessarily to when finding the cutting center of circle
So that the position in the center of circle is accurate relative to the boundary position of material, but can by by setting circle 11 in material to be cut
It is compared, so that its position between the adjacent circular hole cut meets the smallest cutting requirement, thus by be cut
Circular product make rational deployment in material, it is more round to be cut into as much as possible in the material to be cut, prevent
Material is caused to waste, traditional circle of contact device then cannot achieve this function, and can only be judged according to the naked eyes of operator can
For the space of cutting, the waste that will lead to material is excessively securely judged, and excessively bold judgement then will appear cutting room
Inadequate situation generates the waste product of circular boundary incompleteness.
In addition it is also necessary to explanation, the circle of contact device locator of the present embodiment is only applicable in applicant's application before
Circle of contact device structure disclosed in state's utility model patent (notification number CN206357325U), and can not be suitable for other shapes of
Circle of contact device structure.
