Abstract
Provided is an angle measuring instrument of a bolt-sphere. A grid structure is realized by connection of steel pipes and bolt-sphere nodes. A bolt-sphere is an important component of the structure. Using a conventional method to measure angles of the bolt-sphere is troublesome, wastes time and efforts, and measuring efficiency is low. The angle measuring instrument comprises a base (1), the base (1) is provided with a horizontal rotating disk (2). The horizontal rotating disk is connected with an arc-shaped arm support (6). The center of the horizontal rotating disk is provided with a lower thread core bar (11). The arc-shaped arm support is connected with an upper thread core bar (9). The arc-shaped arm support is connected with a rotary guiding hand wheel (8). The rotary guiding hand wheel is connected with a locating rod component (7). The arc-shaped arm support is embedded with a dial (4). The base is embedded with a vernier (3). The base is provided with a group of connecting rods (12). The base is provided with a locking hand wheel (5). The angle measuring instrument is used for measurement of bolt-sphere angles.
Description
technical field:
the utility model relates to a kind of bolt sphere angle measuring instrument.
background technology:
a kind of novel grid structure of building trade is popularized, and is characterized in that part easily processes, convenient and flexible installation, exotic shape.Grid structure is applied mechanics principle, and gravity is carried out to peptizaiton by certain angle, and it is connected realization with bolted spherical node by steel pipe.Bolt sphere is the strength member of this structure, and its crudy directly affects the mechanical property of grid structure.The quality control of bolt sphere has six indexs: 1. ball blank diameter; 2. the circularity of ball; 3. bolt sphere end surface of screw hole and centre of sphere distance; 4. the two end surface of screw hole depth of parallelisms on same axis; 5. angle between adjacent two screw axis; 6. the verticality of end surface of screw hole and axis.Between adjacent two screw axis, angle requires ± 30 ＇, and this parameter is very important, but very loaded down with trivial details with traditional method measurement, wastes time and energy, and measures efficiency low.
utility model content:
the purpose of this utility model is to provide a kind of bolt sphere angle measuring instrument.
above-mentioned object realizes by following technical scheme:
a kind of bolt sphere angle measuring instrument, its composition comprises: base, on described base, horizontal rotating disc is installed, described horizontal rotating disc is connected with arc jib, at described horizontal rotating disc center, lower screw thread core bar is installed, described arc jib is connected with upper screw thread core bar, and described arc jib is connected with rotation guiding handwheel, described rotation guiding handwheel is connected with backstay parts, on described arc jib, studs with scale.On described base, stud with vernier, described base has one group of connecting link, and locking handwheel is installed on described base.
beneficial effect:
1. on base of the present utility model, be provided with rotating disk, the effect of these two parts is to form a Plane Angle rotation system.Rotation axis system can adopt roll structure, and rotation precision is higher, and load-bearing capacity also can reach requirement.Scale division value has been installed on base is the vernier of 2 ＇ simultaneously, is also provided with locking handwheel.On horizontal rotating disc excircle, studding with scale division value is the scale of 360 degree of 30'.Whole horizontal rotating disc system accuracy index is controlled at 3 ＇～4 ＇.On horizontal rotating disc, fix arc jib, on jib, studded with gear and tooth bar, rotated guiding handwheel, by rack-and-pinion effect, driven backstay parts on arc jib, to move together.On arc jib and backstay parts, also stud with scale and vernier in addition, its horizontal axis by the bolt centre of sphere is 0 scale, is upwards positive scale, is negative scale downwards, and measurement range is ± 75 °, and precision is controlled at 3 ＇～4 ＇.Upper and lower screw thread core bar can inside and outside pull respectively on circular arc jib and pedestal, and can fix.Require two screw thread core bars on same axis, and core bar axis direction is carved with circumference index line millimeter scale.
2. the measuring method of this bolt sphere angle measuring instrument is as follows, the bolt sphere of first screwing on lower screw thread core bar, and fixed, be then screwed into core bar, and adjust the equally size of indicating graduation of upper and lower core bar.The object of doing is like this, by standard core bar end face location, to make the horizontal axis of bolt sphere by reality 0 scale mark of arc jib.This being adjusted under same specification measure batch, lower core bar can be motionless, also need not adjust.When concrete reading, first rotate the backstay parts on rotating disk and arc jib, make backstay insert first screw A, piece number: in 13, this backstay front end is with 1:10 tapering, and by contacting location with the crest of internal thread, the method is located given accuracy index.At this moment can read to obtain level angle α 1 and Z direction corner β 1; Then can use same method, location core bar is inserted to second the screw B adjacent with first screw, piece number: 14 interior location.Read again to obtain level angle α 2 and Z direction corner β 2.| α 2-α 1|=α, acquired results α is first screw axis and second screw axis projected angle on surface level, and this angle is also the angle marking on drawing.If α, β 1, β 2 are the same with drawings marked, can think that institute's measuring angle is qualified.If there is deviation, also need to calculate.Obtain the Space Angle value γ marking on the actual measurement Space Angle value of angle and drawing, require be no more than ± 30 ＇.Computing formula is γ=arccos α. cos β.Wherein α is that two screw axis are at surface level projected angle; β is perpendicular to the projected angle in the plane of surface level (β=| β 2-β 1|).
accompanying drawing explanation:
accompanying drawing 1 is structural representation of the present utility model.In figure, 10 is bolt sphere.
embodiment:
embodiment 1:
a kind of bolt sphere angle measuring instrument, its composition comprises: base 1, horizontal rotating disc 2 is installed on described base, described horizontal rotating disc is connected with arc jib 6, at described horizontal rotating disc center, lower screw thread core bar 11 is installed, described arc jib is connected with upper screw thread core bar 9, described arc jib is connected with rotation guiding handwheel 8, described rotation guiding handwheel is connected with backstay parts 7, on described arc jib, stud with scale 4, on described base, stud with trip, 3, described base has one group of connecting link 12, locking handwheel 5 is installed on described base.
