Summary of the invention
The purpose of this utility model is to provide a kind of frock of line, utilizes the frock of this line accurately can mark the string of distance center of circle set a distance on known circle as required, on the known circle with certain altitude, especially accurately marks the string apart from center of circle set a distance.
The purpose of this utility model is achieved through the following technical solutions:
This scribing tooling, comprises crossbeam, column, litter and thimble; Uprights vertical in prismatic crossbeam center line, to move along column center line and be arranged on crossbeam; Litter perpendicular to column center line and crossbeam center line, to move along litter center line and be arranged on column lower end; Thimble is parallel to column center line and moves and arrange on litter; The generatrix direction of litter is carved with graduation mark.
The beneficial effects of the utility model are:
Use above-mentioned scribing tooling, make the side of crossbeam (benchmark) also crossing with thimble axes normal, and thimble axis is overlapped with the pitch circle center of circle; At this moment, litter has a corresponding scale, quantitatively (△ a1) slip litter, also has △ a2 distance, △ a1=△ a2 between crossbeam and the pitch circle center of circle.Rule on workpiece with reference to crossbeam benchmark side (line ruler), be the string apart from center of circle set a distance △ a2 on known circle.
This apparatus structure is simple; Can be suitable for differing heights within the specific limits, different pitch radius, different string apart from pitch circle distance of center circle from string, there is applicability comparatively widely.
As to improvement of the present utility model, crossbeam offers perpendicular to crossbeam center line, the leghole that can limit the column revolving free degree, the column matched with leghole moves and is arranged in leghole; Offer in the lower end of column perpendicular to column center line, the litter hole that can limit the litter revolution free degree, the litter matched with litter hole moves and is arranged in litter hole; Offer the centre hole being parallel to column center line in the outer end of litter, thimble moves and is arranged in centre hole.
Above-mentioned improvement, the structure of further clear and definite scribing tooling, than the frock of aforesaid line, is easier to implement.
As the further improvement to above-mentioned scribing tooling, each cross section of crossbeam is identical rectangle; Each cross section of leghole is identical rectangle; Each cross section in litter hole is identical rectangle.
These improve, and ensure the functional realiey of crossbeam as line ruler, more easily ensure the spatial relation of crossbeam, column, litter, thimble.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail, and be described further use of the present utility model in conjunction with specific embodiments:
See the scribing tooling shown in Fig. 1, Fig. 2, Fig. 3, on the whole, its structure is:
This scribing tooling, comprises crossbeam 1, column 2, litter 3 and top 4; Column 2 perpendicular to prismatic crossbeam 1 center line, to move along column 2 center line and be arranged on crossbeam 1; Litter 3 perpendicular to column 2 center line and crossbeam 1 center line, to move along litter 3 center line and be arranged on column 2 lower end; Top 4 are parallel to column 2 center line moves and is arranged on litter 3; The generatrix direction of litter 3 is carved with graduation mark 5.
Specifically:
Shown in Fig. 4, Fig. 5, each cross section of crossbeam 1 is identical rectangle, crossbeam 1 offers perpendicular to crossbeam 1 center line, can limit the leghole 8 that column 2 turns round the free degree.Each cross section of leghole 8 is now taked to be identical rectangle.In the side of crossbeam 1, also offer the screwed hole 9 communicated with leghole 8, for arranging fastening bolt 6, screwed hole 9 is preferably vertical with leghole 8.
Shown in Fig. 6, Fig. 7, Fig. 8, each cross section of column 2 is identical rectangle, and its object is to column 2 is matched with leghole 8, namely leghole 8 precisely leads for column 2; Offer in the lower end of column 2 perpendicular to column 2 center line, the litter hole 11 that litter 3 turns round the free degree can be limited; Each cross section in litter hole 11 is identical rectangle.In the side of column 2, also offer the screwed hole 10 communicated with litter hole 11, for arranging fastening bolt 7, screwed hole 10 is preferably vertical with litter hole 11.
Shown in Fig. 9, Figure 10, litter 3 is made up of bar handle 15 and center sleeve 16 two parts, and bar handle 15 matches with litter 3 hole; Offer in the outer end (on center sleeve 16) of litter 3 center hole 12 being parallel to column 2 center line, consider from processing technology, center hole 12 is cylindrical hole.Graduation mark 5 is carved with along on the axis direction of bar handle 15 in the side of litter 3 bar handle 15.
Shown in Figure 11, top handle is the cylinder matched with center hole 12, and according to the service condition of this scribing tooling, top handle takes slight interference to coordinate with center hole 12.
Position relationship and the connected mode of above-mentioned each part are:
