Description
Technical field
The present invention relates to machinery processing apparatus, particularly a kind of machinery processing apparatus that band tangent line circular arc is processed.
Background technology
Relate at shipbuilding and other in industry such as steel plate processing, usually need steel plate is processed into the shape that has one section tangent line on the circular-arc and circular arc with certain specification, to be used for the manufacturing of particular component.Because the internal diameter of the circular arc of being processed does not wait or internal diameter equates that the arc length of band tangent line does not wait, so must make processing model, the batten of the wooden or irony of various adaptation workpiece requirement before the processing, what promptly common processing technology was said processes according to sample.
In the prior art, single circular arc processing has all size circular arc processing batten.But when processing the circular arc one or both ends and having the workpiece of suitable length tangent line, add batten only according to circular arc and will determine accurately that point of contact and tangent line acquire a certain degree of difficulty.Be the circular arc processing batten that adopts a band of the system of striking point of contact tangent line at present, make band point of contact batten as the processing foundation in strict accordance with the radius of arc plate to be processed.The shortcoming that exists in the prior art is like this:
1. the circular arc of different radii need be made different band point of contact battens, does not have repeatedly application, the inefficiency that causes the circular arc part to make, and also waste is serious simultaneously.
When 2. processing the band tangent line circular arc of same radius, also must strike the corresponding batten of system when causing and could satisfy process requirements when the circular arc that will process is different in size, this has just increased the cost of making.
3. the maximization of making along with arc plate, the thickness of the band tangent line circular arc spare of being processed increases, and the point of contact that has after batten is processed is incorrect, and circular arc tangential line is less than sample, that gives next procedure correct installation or closing up of parts brings inconvenience, serious meeting to influence the crudy of circular arc part.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, a kind of circular arc tangential line apparatus that can cooperate different circular arc splines to use is provided, the circular arc spline of circular arc spline thread cutter of the present invention and different radii is used point of contact and the tangent position of determining band tangent line part, can make and check the band tangent line circular arc part of different radii, have reusable, convenient and swift, the efficient advantages of higher.
Basic principle of the present invention:
As shown in Figure 1, with O
1A is that the A point on first circular arc of radius is the point of contact, makes tangent line AP, and the length of establishing AP is certain value, crosses the P point again and makes the vertical line of AP and hand over first circular arc in K
1Point is crossed K
1Point is made O
1The vertical line of A is handed over O
1A is in A
1Point by known radius and definite value PA, can calculate and obtain AA so

2Be O
2Second circular arc is made in the center of circle of A, the PK on the tangent section PA
1Point hands over second circular arc in K
2Point then can utilize radius O
2The value of A and tangent line PA is determined PK
2Value.With the A on the straight line PA is the point of contact, hangs down that to get random length as for PA be that radius is made circular arc crossing A point, as long as the mistake P point vertical line of tangent section PA can hand over circular arc in K
