Description
Technical field
The utility model relates to field of machining, particularly relates to the alignment mechanism of circle hole centreline.
Background technology
During general machining, when we need with the round center processed for benchmark time, usual needs are looked for by Digit Control Machine Tool, general way is difficult to precisely find out center, or when performing secondary machining, originally benchmark is more difficult looks for, when wanting to use existing more accurate circular hole as benchmark, the center of circle is also more difficult to be looked for, and adds workload, reduces the reliability of work.
Utility model content
The utility model, for above problem, provides a kind of structure simple, easy to use, the circle hole centreline alignment mechanism that reliability is high.
The technical solution of the utility model is: comprise crossfoot, perpendicular chi and a pair mandrel, described crossfoot is tabular, and the side, center of described crossfoot is provided with storage tank, is provided with connecting hole one in described storage tank,
Described perpendicular chi is tabular, and described perpendicular chi is provided with the connecting hole two corresponding with described connecting hole one,
Described perpendicular chi is fixedly located in the storage tank of described crossfoot, described perpendicular chi is perpendicular to described crossfoot, one side of described perpendicular chi is fitted the center line of described crossfoot, the described end face of perpendicular chi and the end face of crossfoot are in same plane, and the connecting hole one of described crossfoot and the connecting hole two of perpendicular chi are connected by screw;
Vertical and the symmetry of described a pair mandrel is located on described crossfoot.
Described perpendicular chi is provided with cross section breach triangular in shape towards one end of the center line of described crossfoot, and described breach and described a pair mandrel lay respectively at the both sides of described crossfoot.
The utility model is made up of crossfoot, perpendicular chi and mandrel, utilizes theorem of diameter perpendicular to a chord inference, utilize the cylindrical of mandrel and circular hole tangent, and perpendicular chi is vertical and divide crossfoot equally, then a side of perpendicular chi is center line.In use, a pair mandrel is placed in circular hole, up shifts onto with endoporus tangent, like this, conveniently find center line.The utility model does not need to use Digit Control Machine Tool alignment line, especially looks for benchmark to bring great convenience for secondary operations.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model,
Fig. 2 is the top view of Fig. 1,
Fig. 3 is working state figure of the present utility model;
In figure, 1 is crossfoot, and 10 is storage tanks, and 2 is perpendicular chis, 3 mandrels, and 4 is breach, and 5 is circular holes.
Detailed description of the invention
The utility model as Figure 1-3, comprises crossfoot 1, perpendicular chi 2 and a pair mandrel 3, and described crossfoot 1 is in tabular, and the side, center of described crossfoot 1 is provided with storage tank 10, is provided with connecting hole one in described storage tank 10,
Described perpendicular chi 2 is in tabular, and described perpendicular chi 2 is provided with the connecting hole two corresponding with described connecting hole one,
Described perpendicular chi 2 is fixedly located in the storage tank 10 of described crossfoot 1, described perpendicular chi 2 is perpendicular to described crossfoot 1, one side of described perpendicular chi 2 is fitted the center line of described crossfoot 1, the described end face of perpendicular chi 2 and the end face of crossfoot are in same plane, and the connecting hole one of described crossfoot 1 and the connecting hole two of perpendicular chi 2 are connected by screw;
Vertical and the symmetry of described a pair mandrel 3 is located on described crossfoot 1.
Described perpendicular chi 2 is provided with cross section breach triangular in shape 4 towards one end of the center line of described crossfoot 1, and described breach 4 and described a pair mandrel 3 lay respectively at the both sides (i.e. the top of crossfoot, bottom surface) of described crossfoot 1; Breach is set, is convenient to the operation of scriber line.
The utility model operationally, utilizes and to divide equally and perpendicular to string in circle, must through the principle at center, and a pair mandrel of crossfoot is tangent with the endoporus of tested circular hole 5, and crossfoot is equivalent to a string of circle, and perpendicular chi is just equivalent to the vertical and center line of the string divided equally.
