Abstract

The utility model discloses an angle graduation appearance including angle ring, its technical characteristic is that it still includes the reference block of taking the sucking disc, is fixed in the one minute pointer of reference block center department, two minute pointers, three minute pointers, the top insert one minute pointer afterbody guide way second in move fixed connection, two bottoms are fixed in the reference block respectively and the connecting rod on the two minute pointers, be fixed in the guide bar of two minute pointer tail ends, insert guide way first, third and afterbody guide way second, the crossing department of butyl moves fixed handle even as an organic whole. Has the characteristics of simple, convenient, rapid and accurate operation, and the like.

Description

Angle deviding instrument

The utility model relates to the instrument of a kind of angular divisions and tolerance, and it is suitable for need such as pincers worker, panel beating worker the angle of workpiece is carried out two, three and the occasion of integral multiple five equilibrium.

In background technology, need such as pincers worker, panel beating worker adopt ruler, compasses, protractor to carry out to the angle five equilibrium and the tolerance of workpiece always, cause that operation is very cumbersome, time-consuming, the not high defective of the degree of accuracy,, angular divisions and tolerance are developed for overcoming these defectives.

The purpose of this utility model provides the angle-differentiated instrument of a kind of easy and simple to handle, quick, accurate, five equilibrium and tolerance angle.

The purpose of this utility model is achieved in that

It comprises the reference block of being with sucker, be fixed in one fen pointer of the difference magnetic tape trailer portion gathering sill second and the fourth of reference block center, three fens pointers, be fixed in two fens pointers of tape guide groove third on the middle plumbing bar between center and the tail end of reference block center, the top is inserted and was moved fixedly connected in the pointer afterbody gathering sill second in one minute, two bottoms are individually fixed in the connecting rod on reference block and the two fens pointers, be fixed in the guide post of the tape guide groove first of two fens pointer tail ends, insert the gathering sill first, third and afterbody gathering sill second, the handle that fixedly is connected as a single entity is moved in the fourth intersection, is fixed in the angle ring at reference block two ends.One fen pointer, two fens pointers, the pointer end of three fens pointers is provided with marking groove.

Fig. 1 is an enforcement structure chart of the present utility model.

Fig. 2 is a schematic diagram of the present utility model.

Below in conjunction with accompanying drawing, the utility model is done to describe further:

Because NP is the middle plumbing bars 9 of two fens pointers 1 between reference block 5 centers 0 and pointer 1 tail end E, ON=NE then, the vertical OE of NP, NP is public limit, so right angled triangle PON is congruent to right angled triangle PEN, thereby angle PON equals angle PEN, and the included angle A OB of angle PON and three fens pointers 14 and two fens pointers 1 is vertical angles, angle PEN and angle BOD are angle of circumference and the central angle with arc BCD, then NEP=1/2 angle, angle AOB=angle BOD.Because OC is one fen pointer 2, and promptly OC is an angle BOD bisector, angle BOC=angle COD then, thereby BOC=angle, BOD=angle, AOB=1/2 angle, angle COD are so can as if halving, use one fen pointer 2 and two fens pointers 1 just can angle AOD trisection again.If halve, the integral multiple five equilibrium of trisection, halve in an angle of only need to halve, trisection is later, trisection just can again.

Earlier with one fen pointer 2, pointer 1 in two minutes, three fens pointer 14 usefulness glue or screw etc. are fixed in the center of reference block 5, the top of connecting rod 13 is moving to be fixed in one fen pointer 2 afterbody gathering sill second 8, two bottoms are fixed on two fens pointers 1 and the reference block 5 with glue or screw etc., one usefulness glue of guide post 4 or screw etc. are fixed in the tail end of two fens pointers 1, handle 12 is inserted afterbody gathering sill second, fourth and gathering sill first, third intersection, allow it nimbly and freely, again angle ring 3 usefulness glue or screw etc. are fixed in the two ends of reference block 5, just can constitute angle-differentiated instrument of the present utility model.

Wait to need five equilibrium or and during tolerance workpiece angle, reference block 5 one side with the workpiece angle is overlapped, utilize its sucker 16 to be positioned on the workpiece, shake handle 12, affect two

fens pointers

1 and 14, two fens pointers 1 of three fens pointers also to affect guide post 4 and connecting rod 13 simultaneously by it, affect pointer 2 motions in a fen by connecting rod 13 again, when two fens pointers 1 and quilt wait the another side at branch workpiece angle to overlap,, just can realize bisection and measure in marking groove 15 line of one fen pointer 2, two fens pointers 1; When three fens pointers and quilt wait the another side at branch workpiece angle to overlap, rule at the division groove 15 of one fen pointer 2, two fens pointers 1, three fens pointers 14, just can realize trisection and tolerance thereof.If need again quilt waited that branch workpiece angle carries out two, during branches such as the integral multiple tolerance of trisection, only need will carry out two, the later angle of trisection carries out two again, trisection just can realize.

The utility model is compared the good effect that produces with background technology:

1, easy and simple to handle.

2, speed is fast.

3, degree of accuracy height.
