Embodiment
Fig. 1 is the stereographic map of the utility model embodiment bolt corner indicating device, and Fig. 2 is the sectional view of the utility model embodiment bolt corner indicating device; The bolt corner indicating device of the present embodiment is used to indicate the rotational angle of bolt 1 relative installation panel 2 in pretension process, and the bolt corner indicating device of the present embodiment comprises: sleeve 3, indicator 4 and index dial 5; Sleeve 3 is for rotating bolt 1, and on it, operated by rotary motion is useful on and the inner hexagonal hole of head 10 tablings of bolt 1; Indicator 4 is fixed on sleeve 3, can enter to rotate with sleeve 3; Index dial 5, for being fixed on installation panel 2, is provided with center pit on index dial 5, and sleeve 3 is rotatably coaxially arranged in this center pit.On indicator 4, be fixed with pointer 40, when sleeve 3 rotates, pointer 40 slides on index dial 5; On the end face of index dial 5, be provided with the scale mark for identifying pointer 40 slip angle.Indicator 4 is general adopts dismountable mode to be fixed on sleeve 3, can certainly adopt the fixed form such as welding, bolt connection.
Certainly, it should be noted that at this, sleeve 3 in use also can be for rotating screw cap, thereby makes indicating device be used to indicate the rotational angle of the relative installation panel 2 of nut.
The bolt corner indicating device of the utility model embodiment, by being set respectively on bolt 1 and installation panel 2 in relative rotation, pointer 40 and index dial 5 show the angle that relatively rotates of bolt 1, thereby realize the accurate measurement to bolt 1 rotational angle, avoid traditional visual type to estimate coarse problem, thereby made bolt 1 reach more accurately pretension requirement.In addition, because indicator 4 is fixed on sleeve 3, the indicating device of the present embodiment can be applied to bolt and the installation panel of any model, only need change according to bolt 1 sleeve of corresponding size.
On the basis of above-described embodiment, indicator 4 is circular-arc, and the inside surface of indicator 4 is the arc surface coordinating with sleeve 3 external diameters; In other words, a side of indicator 4 is inner arc surface, and the shape of this inner arc surface is identical with the external diameter shape of sleeve 3; So indicator 4 preferably adopts tile structure, so that indicator 4 is good and sleeve 3 fits, also facilitate indicator 4 to be fixed on sleeve 3.Generally, pointer 40 is fixed on the outer arc surface of tile framework.
Fig. 3 is another angle stereographic map of the utility model embodiment bolt corner indicating device, on the basis of above-described embodiment, further, is also provided with rubber ring 41 on indicator 4, and indicator 4 is closely set on the external diameter of sleeve 4 by rubber ring 41.Especially, the in the situation that of being inner arc surface in indicator 4 one sides, indicator 4 adopts on the sleeve that is fixed on different-diameter size 3 that rubber ring 41 can be more convenient.Certainly, indicator 4 can adopt to be had certain flexible material and makes, to facilitate better and sleeve 3 fits.
On the basis of above-described embodiment, further, index dial 5 is fan dial or fan dial.Certainly,, when index dial 5 is fan dial or fan dial, on semicircle and fan-shaped centre point, only need offer the breach for holding bolt 1.Owing to just needing to carry out angle instruction after the certain moment of bolt 1 pretension, the maximum angle of instruction corner is generally all no more than 180 degree, so index dial 5 adopts the fan-shaped or semicircle needs that can meet angle instruction.And index dial 5 can be made up of multiple fan dials or fan dial, to meet angle and the structural environment demand of installed surface; Such as being designed with broken belt on some installation panel 2, index dial 5 can only be put together by multiple fan dials.
It should be noted that in addition, index dial 5 is no matter adopt fan dial or fan dial, and while being fixed on installation panel 2, the axis of the circle central axis of index dial 5 and bolt 1 coincides, to ensure that the pointer 40 on indicator 4 well slides on index dial 5.
Fig. 4 is the upward view of the utility model embodiment bolt corner indicating device; On the basis of above-described embodiment, on the bottom surface of index dial 5, be provided with for being adsorbed on magnet 50 or the sucker on installation panel 2; Magnet 50 can fix with installation panel 2 easily, especially in the time that installation panel 2 is the magnetic flat board of tool; And magnet 50 is fixing owing to adopting, it is very convenient to mount and dismount, and is also difficult for touching index dial 5 when sleeve 3 rotates; Certainly the index dial that index dial 5 also can directly adopt magnet to make.When the bottom surface of index dial 5 is provided with sucker, can contact with level and smooth installation panel 2 easily, and counter plate can not produce any infringement.
On the basis of above-described embodiment, further, pointer 40 ends are fixed on indicator 4, on its one end, are fixed with chalk; Pointer 40 slides on index dial 5 by chalk.Like this, pointer 40, calculating before angle, does not just need the initial position of record pointer deliberately, the angle turning over can be directly by drawing with coloured chalk on index dial, facilitate operation, made operating personnel can directly read rotational angle, greatly improved the work efficiency of accurate pretension bolt.
Because bolt 1 is to rotate after having applied a fixing moment of torsion again, due to the effect of pitch, each angle of therefore rotating can make final pretightning force occur to change comparatively significantly.The bolt corner indicating device that adopts the present embodiment, the rotational angle of bolt once can be as accurate as often, had greatly improved the precision of bolt pretightening, thereby made web member more reliability and durability in the situation that ensureing bolt life.
Finally it should be noted that: above each embodiment, only in order to the technical solution of the utility model to be described, is not intended to limit; Although the utility model is had been described in detail with reference to aforementioned each embodiment, those of ordinary skill in the art is to be understood that: its technical scheme that still can record aforementioned each embodiment is modified, or some or all of technical characterictic is wherein equal to replacement; And these amendments or replacement do not make the essence of appropriate technical solution depart from the scope of the each embodiment technical scheme of the utility model.
