Fig. 2 is the structural representation of index dial in Fig. 1;

Fig. 3 is the structural representation of connecting shaft in Fig. 1;

Fig. 4 is the structural representation of alidade in Fig. 1.

Specific embodiment

A kind of implementation of rotating shaft angle measurement unit is for example shown in Fig. 1 ~ 4:Match somebody with somebody including index dial 4 and with the rotation of index dial 4 The tumbler of conjunction, tumbler includes the connecting shaft 1 and alidade 2 of split setting, is provided with connecting shaft 1 for be measured with corresponding The rotation stop fit structure that rotary shaft rotation stop coordinates.Connecting shaft 1 is hollow-core construction, and the hole wall of the endoporus 12 of connecting shaft has two lateral incisions Straight flange, rotation stop fit structure include coincideing rotation stop be plugged in the endoporus of connecting shaft for the switching that is connected with rotary shaft to be measured Axle(Not shown in figure).

Alidade 2 is arranged at the upper end of connecting shaft 1, and the upper end of connecting shaft 1 is provided with connection land 10, is set on alidade There is the bolt penetration hole 16 along the vertical direction through alidade, the screwed hole corresponding with bolt penetration hole is provided with connection land 14, the fixing bolt for realizing that connecting shaft is fixed with alidade is coated with bolt penetration hole and screwed hole(Not shown in figure).Vernier The land avoidance step 17 for avoiding connection land is provided with disk 2, such alidade 2 can be avoided connecting land 10, it is ensured that trip The lower surface of bidding quotation presses close to the upper surface of index dial 4 as far as possible.Recess upward outer is provided with the outer fringe position of alidade 2 Edge platform rank 18, outer rim step 18 causes that the outermost end of alidade forms thin-slab structure, is set on the bottom stage face of outer rim step Have as the indicating graduation 3 of instruction structure, the angle index that center is on the pivot center of tumbler is provided with index dial 4 5, angle index 5 is 1 degree for 0 ~ 90 degree with double graduation mark clockwise and counterclockwise, per small lattice scale.Indicate Symmetrical graduation mark centered on scale, the graduation mark of center is zero graduation line, is starting point respectively along up time with zero graduation line Pin and counter clockwise direction respectively have ten small lattice scales.Because indicating graduation is located on the thin-slab structure of alidade, and thin-slab structure Press close to index dial again, therefore be easy to reading.Pilot hole 6 is provided with index dial 4, pilot hole 6 is stepped hole, and connecting shaft 1 has Have the load segment 11 being arranged in pilot hole 6, load segment 11 is rotatably assorted by rolling bearing with pilot hole 6, in connecting shaft 1 in The both sides up and down of rolling bearing are respectively arranged with limited step 9 and jump ring mounting groove 13, are provided with jump ring mounting groove 13 and axle The jump ring that bearing outer-ring block coordinates(Not shown in figure), bearing (ball) cover is fixed with index dial 4.The first spiral shell is provided with index dial The screwed hole 7 of pit 8 and second, the first screwed hole is used to install bolt and realize for index dial being fixed on support, by support Index dial is fixed in actionless mechanism part, the second screwed hole realizes the fixation of bearing cap for installing bolt. Figure middle term 15 represent be arranged on alidade for the suit hole that is sheathed in connecting shaft.

When using, support is connected on index dial by bolt first, secures the stand to actionless mechanism part On part, then rotary shaft to be measured is connected with the Coupling Shaft inserted in connecting shaft, can led between rotary shaft to be measured and Coupling Shaft Cross shaft coupling connection, it is also possible to connect by mutual rotation stop inserting, because Coupling Shaft and connecting shaft rotation stop coordinate, therefore rotation to be measured Axle and connecting shaft synchronous axial system, and then cause that the alidade being connected with connecting shaft keeps synchronous axial system with rotary shaft to be measured, therefore Alidade is the rotational angle of rotary shaft to be measured with the Relative angular displacement of index dial.The rotating shaft angle measurement unit is installed When, the angle of indicating graduation and index dial can be made by adjusting the installation site of the angle and index dial of Coupling Shaft on support Scale alignment zeroing(I.e. initial reading is zero degree).Zeroing is divided into zeroing clockwise and zeroing counterclockwise again, with specific reference to be measured Rotate depending on rotational axis direction, if rotary shaft to be measured is to rotate clockwise, returned to zero clockwise, i.e. zero quarter of indicating graduation Line aligns with zero groove of clockwise direction scale on index dial, otherwise is then zeroing counterclockwise.After zeroing, you can operation machine Structure, after rotary shaft to be measured rotate in place, now carries out corner reading, by taking zeroing clockwise as an example, is first read on index dial and referred to Show the groove of scale zero with left scale value, the value is the integer part of last reading, is then read and index dial on alidade The groove lattice number of graduation mark alignment is simultaneously multiplied by 0.1 degree, and the value is the fractional part of last reading.

The present apparatus is not required to scribing operation, can directly read the rotational angle of rotary shaft to be measured, easy to operate, measurement error value It is small;And can be by designing different support and Coupling Shafts, it is adaptable to the rotational angle of the different rotary shaft to be measured of various structures Measurement, highly versatile;Alidade is set with connecting shaft split, simplifies the structure of product, advantageously reduces being fabricated to for device This.In other embodiments of the present utility model:Alidade can also be integrally formed with connecting shaft;When the survey to rotary shaft to be measured When accuracy of measurement is less demanding, indicating graduation can also only include zero graduation line, and it is linear that certain instruction structure may not be scale Formula, such as instruction structure includes being arranged at indicator on alidade, by indicator and angle index with and come reading The rotational angle of alidade;The endoporus of connecting shaft can also be the interior square holes such as four directions, five sides;When rotary shaft to be measured has and is connected During the inserting section of the identical inserting of the endoporus of axle, Coupling Shaft can not also set, directly by rotary shaft rotation stop inserting to be measured in connecting shaft Endoporus in, now rotation stop fit structure is made up of the endoporus of connecting shaft;Certain connecting shaft can also be a solid axle construction, Outer square shaft now can be set in connecting shaft, the interior square hole being arranged with outer square shaft rotation stop is provided with Coupling Shaft;Connecting shaft with point Can not also realize being rotatably assorted by rolling bearing between scale, such as when the machining accuracy of the outer peripheral face of connecting shaft is higher When, connecting shaft directly can coordinate with index dial contact slide;Support can not also set, and directly can now fix index dial In in fixed mechanism part.
