Abstract
The utility model belongs to the field of measurer, which provides a drawing ruler special for positioning a hole for solving the problem that larger error is easy to happen in the central position of the hole in process of drawing operation and the central position of the hole is needed to adjust repeatedly to halve, which takes more time. The drawing ruler special for positioning a hole comprises a main ruler, a positioning block, a centering block, an angle measuring ruler and a hole positioning block. The positioning block and the centering block are sleeved on the main ruler, the centering block is provided with a fan-like angle measuring area and the angle measuring ruler is in rotating connection with the centering block through a bolt. The hole positioning block is sleeved on the angle measuring ruler. The utility model is simple to operate and convenient to use. The position of the hole can be obtained by calculation after an edge is positioned during hole positioning, thereby reducing the calculation error, saving the positioning time and improving the work efficiency.
Description
Technical field
The utility model belongs to the measuring appliance field, and special-purpose marking-out rule is located in especially a kind of hole.
Background technology
In factory's actual production process; Some dish types (annular) workpiece need carry out drilling machine boring processing; Must accurately locate the hole via the line pincers worker before the processing; The conventional positioning mode is to make the position of the center in hole to the center of circle earlier according to drawing, again according to the center in hole to the distance in the center of circle and the utilization of the angle between two holes cosine law calculate between the center, two holes apart from d, will plan again to be adjusted to and wait the graduation hole apart from d.But in actual computation, the value of d often is not an integer, has so just caused the center of line operating process mesopore to exist than mistake, needs the five equilibrium of adjustment ability repeatedly, has wasted a large amount of production times, has brought inconvenience.
The utility model content
The utility model is intended to address the above problem, and provides a kind of hole to locate special-purpose marking-out rule and has obtained certain beneficial effect, and its technical scheme that adopts is following:
A kind of hole is located special-purpose marking-out rule and is comprised main scale, deckle piece, center bridge, angle square, hole locating piece, and said deckle piece and center bridge are sleeved on the main scale, can slide along main scale;
Said center bridge is provided with fan-shaped measurement of angle district, is rotationally connected through bolt between said angle square and the center bridge, and angle square can rotate around center bridge;
Said hole locating piece is sleeved on the angle square, can slide along angle square.
On the technique scheme basis, the position of the back side zero graduation line of said main scale is connected with a thimble, is convenient to the location;
Said deckle piece 2 center positions are connected with a thimble, and thimble can be fixed on the deckle piece on the main scale through screwing;
The center position of said hole locating piece 5 is connected with a thimble, is convenient to the location of central point of hole.
On the technique scheme basis, the forward, central part of said center bridge has a groove, and said angle square has a groove in the position that overlaps with center bridge angle index line, is convenient to reading of scale.
On the technique scheme basis, said hole is located all parts of special-purpose marking-out rule and is all adopted steel No. 45.
Compared with prior art, the utlity model has following advantage: simple to operate, easy to use, the hole only needs once to calculate the position that just can obtain the hole behind the deckle during location, has reduced the error of calculation, has saved positioning time, has improved work efficiency.

Embodiment
Below in conjunction with accompanying drawing and instance the utility model is described further:
Extremely shown in Figure 6 like Fig. 1; Special-purpose marking-out rule is located in a kind of hole of the utility model; Comprise main scale 1, deckle piece 2, center bridge 3, angle square 4, hole locating piece 5, said deckle piece 2 is sleeved on the main scale 1 with center bridge 3, and said center bridge 3 is provided with fan-shaped measurement of angle district; Be rotationally connected through bolt between said angle square 4 and the center bridge 3, said hole locating piece 5 is sleeved on the angle square 4.
Preferably, the position of the back side zero graduation line of said main scale 1 is connected with a thimble, and said deckle piece 2 center positions are connected with a thimble, and the center position of said hole locating piece 5 is connected with a thimble.
Preferably, the forward, central part of said center bridge 3 has a groove, and said angle square 4 has a groove in the position that overlaps with center bridge 3 angle index lines.
Utilize main scale 1 and deckle piece 2 can fix workpiece and measure diameter of work during use; Slide with center bridge 3 definite workpiece centre positions according to diameter; Utilize the thimble on the hole locating piece 5 to make the center of circle that the hole belongs to according to drawing requirement, can obtain the exact position in each hole again by the angle swinging angle square 4 between two holes.
With way of example the utility model is illustrated above, but the utility model is not limited to above-mentioned specific embodiment, all any changes done based on the utility model or modification all belong to the utility model and require the scope protected.
