Description
Technical field
The utility model relates to manufacture of steel structure manufacture field, and more particularly it is a kind of bolt hole distance measuring device.
Background technology
At present, the measurement of the bolt hole pitch-row of having bored on for member in construction steel structure industry, is all generally to adopt steel tape measured hole edge to the distance of another bore edges, and it is larger that the method is affected by surveyor's subjective judgement, and measuring accuracy is lower.
Chinese invention patent application < < measures the device > > (publication number: CN62679846A) disclose a kind of device of measuring bolt hole distance of bolt hole distance, comprise two stopples and chi, for direct-detection pitch-row, but the sign corresponding with the hole heart of bolt hole is not set on its stopple, the heart position, hole that needs human eye judgement bolt hole, cause measuring error larger, measuring accuracy is not high; In addition, its stopple bottom is cylindrical structural, is only applicable to the range observation of the bolt hole of fixed measure, and the scope of application is less.
Summary of the invention
The purpose of this utility model is to overcome the weak point of above-mentioned existing background technology, and provide a kind of simple in structure, bolt hole distance measuring device that measuring accuracy is high, applied widely, make the measurement of bolt hole spacing not affected by survey crew subjective judgement, pitch-row is measured more accurate, directly perceived, objective.
The purpose of this utility model reaches by following measure: bolt hole distance measuring device, it comprises initiating terminal stopple, reading stomidium plug and ruler, its special character is, the top of described initiating terminal stopple is cylindrical structural, footpath, top is upwards provided with ruler draw-in groove, the top of described reading stomidium plug is semicircle tapered structure, circular cone top cusp forms pointer, the middle part of described initiating terminal stopple and reading stomidium plug is annular round platform, bottom is up big and down small conical structure, one end of described ruler is positioned at the ruler draw-in groove of initiating terminal stopple, the other end places on the annular round platform of described reading stomidium plug.
In technique scheme, on the annular round platform of described initiating terminal stopple and reading stomidium plug, be symmetrically arranged with stopple leveling bolt.The stopple leveling bolt of described initiating terminal stopple and reading stomidium plug is four, is evenly arranged on annular round platform.Four symmetrically arranged stopple leveling bolts can be adjusted the horizontal level of stopple, prevent that stopple from tilting to drive ruler to tilt to cause measuring error.
In technique scheme, the upper surface of the bottom of described ruler draw-in groove and initiating terminal stopple annular round platform maintains an equal level, and ruler is positioned in same level, prevents that ruler from tilting to cause measuring error.
In technique scheme, described initiating terminal stopple top center position and ruler draw-in groove vertical direction are provided with zero reference draw-in groove, the zero reference of ruler is alignd with zero reference draw-in groove, survey crew can be between reading end reading, zero reference draw-in groove identifies the heart position, hole of bolt hole, improves measuring accuracy.
In technique scheme, on the ruler draw-in groove wall of described initiating terminal stopple, be provided with ruler set bolt, ruler is fixed, prevent that its shift in position from causing measuring error.
The utlity model has following advantage:
1). simple to operate, when measuring bolt hole, without artificial experience judgement, get final product direct reading, stopped artificial subjective judgement error.
2). measuring accuracy is higher, because this measurement device is of a size of the spacing of Xin Dui hole, the hole heart, not only directly perceived and precision is higher.
3). the applicable pore diameter range of measurement mechanism is wider, because the conical stopple of this bottom of device can adapt to the measurement that different pore size carries out pitch-row.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the structural representation of initiating terminal stopple in Fig. 1;
Fig. 3 is the structural representation of reading stomidium plug in Fig. 1.
In figure: initiating terminal stopple 1, reading stomidium plug 2, ruler 3, annular round platform 4, ruler draw-in groove 5, ruler set bolt 6, stopple leveling bolt 7, zero reference draw-in groove 8, pointer 9, web joint 10 to be measured.
Embodiment
Below in conjunction with accompanying drawing, describe performance of the present utility model in detail, but they do not form to restriction of the present utility model, only for example.Simultaneously by illustrating that advantage of the present utility model will become more clear and easily understand.
Consult Fig. 1 to Fig. 3 known: the utility model bolt hole distance measuring device, it comprises initiating terminal stopple 1, reading stomidium plug 2 and ruler 3.The top of initiating terminal stopple 1 is cylindrical structural, and middle part is that annular round platform 4, bottom are up big and down small conical structure.Initiating terminal stopple 1 footpath, top is upwards provided with ruler draw-in groove 5, on ruler draw-in groove 5 walls, is provided with ruler set bolt 6, and the upper surface of the bottom of ruler draw-in groove 5 and the annular round platform 4 of initiating terminal stopple 1 maintains an equal level.Initiating terminal stopple 1 top center position and ruler draw-in groove 5 vertical direction are provided with zero reference draw-in groove 8.On the annular round platform 4 in middle part, be provided with symmetrically four stopple leveling bolts 7.
The top of reading stomidium plug 2 is semicircle tapered structure, and circular cone top cusp forms pointer 9, and middle part is annular round platform 4, is provided with symmetrically four stopple leveling bolts 7 on annular round platform 4, and bottom is up big and down small conical structure.
