Description
Technical field
This utility model belongs to bend pipe manufacturing, especially relates to the line tool of a kind of machine-building.
Background technology
The demand that industrial pipes product is mainly used in the emerging fields such as the industries such as oil, petrochemical industry, chemical industry, natural gas, boats and ships, electric power, medicine, combustion gas, heating power especially shale gas, ocean engineering and nuclear power is more huge, there is specificity strong, surcharge is high, widely used feature, is the indispensable important pressure pipeline element of the national economic development. And bend pipe has greatest relation for links such as turning, shuntings, general elbow to carry out groove process after processing and be easy to better connect other pipeline, but for the large-scale bend pipe without straight length, precisely line is needed during bent tube bevel, strike flat and vertical centering control separated time of method before using looks for an amount scale, cumbersome, and when running into without bend pipe (general more than 1 meter) that straight length radius is big, not having suitable face plate, cannot directly rule carries out groove operation at all.
Rule without the bent tube bevel of straight length and first to draw separated time and a vertical centering control separated time in two levels of bend pipe, and beat datum mark at port 5 centimeters place, in extending level, two end points of separated time are to an intersection point, measure the structure length of both sides bend pipe afterwards respectively, and two chord lengths, according to surveyed data with cosine law calculating and the actual angle verifying bend pipe. Adopt line band or tape measure correspondence vertical centering control separated time to draw respectively a little afterwards, add flat mouth surplus 10, mark circumference line of cut. But there is no suitable face plate for large-scale bend pipe, it is impossible to accurately measure line.
Utility model content
The purpose of this utility model is in that to provide a kind of large-scale bend pipe scribed circle scale, need not calculate and just can directly rule.
The technical solution of the utility model is:
Large-scale bend pipe scribed circle scale, including ruler handle, left branch leg, right supporting leg, the top of left branch leg, right supporting leg top be all rotationally connected with the lower end of ruler handle, left branch leg, right supporting leg are equipped with scale, left branch leg, right supporting leg high scale left branch leg respectively, being uniformly distributed along bearing of trend of right supporting leg, the lower end of left branch leg, right supporting leg lower end be equipped with telescoping section, the telescopic direction of telescoping section is consistent with the bearing of trend of place supporting leg; Described right supporting leg is fixedly connected with one end of angle graduated scale, left branch leg is provided with limited post, angle graduated scale is arc, the centre of angle graduated scale arcuately bearing of trend is provided with locating slot, outer one end of described limited post is positioned at locating slot, and angle graduated scale arcuately direction is provided with angle index.
Limited post and locating slot are slidably connected.
Described limited post is cylindrical.
The top of limited post is provided with limited block.
The projected size of limited block is more than the cross section size of limited post.
Described left branch leg, right supporting leg the upper end of telescoping section be correspondingly positioned at respectively in left branch leg, right supporting leg.
The lower end of described telescoping section is plane, and plane is vertical with the bearing of trend of place left branch leg, right supporting leg.
This utility model provides a kind of large-scale bevel protractor groove scoring tool of compasses-type, and the large-scale bevel protractor equipment of this compasses-type is simple, and cost is low, only with simply welding; Need not calculate during operation, need not specialty face plate, further saving of work and time, it is greatly improved production efficiency, can save the halfhour time with the every bend pipe line of large-scale bevel protractor, more can precisely ensure bend pipe structure length, bend pipe angle and morpheme size, can better carry out groove operation. Adopt 45 degree and 90 degree large-scale compasses-type bevel protractors of the present utility model to have good positioning the bending radius of equal proportion, can complete then along line outside large-scale angle square.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
As shown in Figure 1, large-scale bend pipe scribed circle scale of the present utility model, including ruler handle 1, left branch leg 2, right supporting leg 3, the top of left branch leg 2, right supporting leg 3 top be all rotationally connected with the lower end of ruler handle 1, left branch leg 2, right supporting leg 3 are equipped with scale 4, scale 4 on left branch leg 2, right supporting leg 3 left branch leg 2 respectively, being uniformly distributed along bearing of trend of right supporting leg 3, the lower end of left branch leg 2, right supporting leg 3 lower end be equipped with telescoping section 5, the telescopic direction of telescoping section 5 is consistent with the bearing of trend of place supporting leg; Left branch leg 2, right supporting leg 3 the upper end of telescoping section 5 be correspondingly positioned at respectively in left branch leg 2, right supporting leg 3. The lower end of telescoping section 5 is plane 6, and plane 6 is vertical with the bearing of trend of place left branch leg 2, right supporting leg 3.
Being fixedly connected with the right-hand member of angle graduated scale 7 on right supporting leg 3, left branch leg 2 is provided with limited post 8, and angle graduated scale 7 is arc, and the centre of angle graduated scale 7 arcuately bearing of trend is provided with locating slot 9, and limited post 8 and locating slot 9 are slidably connected.
Outer one end of limited post 8 is positioned at locating slot 9, and angle graduated scale 7 arcuately direction is provided with angle index 10.
Limited post 8 is cylindrical. The top of limited post 8 is provided with limited block 12. The projected size of limited block 12 is more than the cross section size of limited post 8. To prevent angle graduated scale 7 from coming off from limited post 8.
Left branch leg 2, right supporting leg 3 are placed on required groove bend pipe 11.
Use procedure:
In operation, large-scale for compasses-type of the present utility model bevel protractor is placed on bend pipe 11 according to the angle of bend of bend pipe, guarantee that the centrage of bend pipe is consistent with the centrage of bevel protractor, bevel angle according to bend pipe 11, bevel protractor is adjusted corresponding angle, lie in a horizontal plane on bend pipe, then rule can complete along the outside of bevel protractor.
