Description
Technical field
The present invention relates to machine-building, particularly a kind of scoring tool to large-scale circular part concentric circular arc.
Background technology
In mechanical manufacturing field and engineering field, a lot of occasions relate to the large-scale circular part, these circular pieces are added need process interior circular arc man-hour.So just need special instrument or special method to carry out the line operation of interior circular arc, reach concrete application purpose.
Prior art comprises following several in the cylindrical or the endoporus alignment method of circular parts: the axle center of small-sized axial workpiece is to draw the axle center cross hairs or alignment cross hairs on " V " type piece by the central cross chi.Bigger circular pieces is then used the scriber clamp, drawing " # " font on four points of circumference, then at the center centre punch of " # " font, rush to central point, be the center of circle with the central point, utilize scriber clamp inspection outer arc all around, see that whether central point is at the center.Then correct if any deviation, and then check the center, till correct with remedy.
For ring-shaped work pieces, can at first form a central portion, and then utilize said method to find central point accurately with stuffing process.It then is to utilize geometrical principle that major diameter is lacked ring-shape accessory, and the method for the three-point circle heart is found out central point.To ultra-large type part circle diameter or radius, the scribble method in the past then method with the front is similar, only used tool is amplified lengthening.
The location determining method of the screw hole around on ultra-large annular part such as cutting ring of shield, the ring, utilize the formula of " circumference in equal parts chord length factor table ": a=R * K obtains the distance of chord length, a is that chord length, R are that radius, K are the coefficient of circumference in equal parts in the formula, utilizes this formula to mark bisector on the circumference of any five equilibrium.On the circle diameter of ultra-large type part, radius, the arc radius rule in the position in hole, at first will find the central point of circle or circular arc, uses the compasses greater than radius, two people to cooperate and radius arc could be marked then.
But draw such radius, tend to be subjected to the restriction of condition and be difficult for finding central point accurately and do not have suitable scoring tool, thereby seem difficult.
Summary of the invention
The objective of the invention is to overcome above-mentioned the deficiencies in the prior art, a kind of scoring tool of concentric circular arc of large-scale circular part is provided.Utilize scoring tool of the present invention to draw inside and outside circular arc operation, reach easy to use, line precision height, and the purpose of highly versatile circle or circular arc and ring-shape accessory.
The making principle of instrument of the present invention:
When on general circular pieces, drawing, can directly adopt large-scale compasses to mark this concentric circles with circular arc.But, perhaps run into ring-shaped work pieces or when being non-full circle shape part, just be inconvenient to adopt the tradition of compasses to draw concentrically ringed method along with the increase of circular pieces size.The present invention is on the basis that large-scale circular part outer circular edge or interior circular arc are determined, adopt the thinking opposite with prior art, abandon the method that instruments such as utilizing compasses behind original definite center of circle is drawn the concentric circular arc, adopting with cylindrical or interior circle is benchmark, draws the circular arc of concentric around the outside.
In view of the above, we adopt following technical scheme:
A kind of scoring tool of large-scale circular part concentric circular arc, the structure of this instrument mainly comprises basic body, be connected in described base pipe shaft on one's body, be through at scribing block and micropositioning stage on the described pipe shaft, the bottom of described basic body is provided with action roller, one end of described pipe shaft is fixed on one's body the described base rotationally by a connecting bolt, the other end of pipe shaft can this connecting bolt be that rotate up and down in the center of circle, described scribing block and micropositioning stage link into an integrated entity by a fine setting screw rod, be installed with a minitrim wheel that is stuck in the micropositioning stage on the described regulating rod, the bottom of described scribing block is provided with a scriber, described scribing block and micropositioning stage can be free to slide on body, and can be fixed in the optional position of pipe shaft respectively by the screw on scribing block and the micropositioning stage.
Described pipe shaft is that the aluminum pipe of lightweight is made.
Described basic body is adjusted bolt by two splits by a matrix circular arc and is linked into an integrated entity rotationally.
The action roller of described basic body bottom is symmetrically arranged four rolling, and two basic status body bottoms are respectively established two.
The elongation of described scriber can be adjusted.
Technique effect of the present invention:
Adopt the scoring tool of big circular pieces concentric circular arc of the present invention, can on the part of various circles, semicircle or arc, mark circular arc, radius or diameter.Adopt light-duty hard aluminium alloy tubing, mix movably active scriber.When doing benchmark with cylindrical or endoporus, the pipe shaft upset, micropositioning stage and scribing block are all rotatable, flexible Application.
