In, to command machine tooling part.It is mainly used for the inside and outside cylindrical surface of axial workpiece or disk-like accessory, any cone angle it is interior
The machinings such as positive camber and cylinder, tapered tread in outer conical surface, complicated revolution, and can be carried out grooving, drilling, reaming, hinge
Hole and bore hole etc..
Raising of the numerically-controlled machine tool due to whole manufacture level, and high compound, highly integrated design, many enterprises are correspondingly
It is proposed highly integrated complex milling machine tool product.The characteristics of this lathe is that Milling Process may be implemented on the basis of turning, main
Axis can index and the use of interpolation axis is done in the conversion of Cs axis, then consequent is that main shaft is converted to the position precision after Cs axis
Check problem.It tests usually using laser interference angle-measuring method, advantage is accuracy height, and signal uniformity is good, can achieve
The accuracy that usual method is not achieved, therefore widely applied in High-precision angle measurement, the disadvantage is that structure is complicated, light
Road adjustment, detection process take long time, and high-precision detecting instrument is more expensive, is unfavorable for in-site measurement, make its practical application by
To limitation.
Summary of the invention
The purpose of this utility model is to provide a kind of adjustable rotary shaft positioning accuracy detecting tools, to solve above-mentioned back
The problem of being proposed in scape technology.
To achieve the above object, the utility model provides the following technical solutions:
A kind of adjustable rotary shaft positioning accuracy detecting tool, including spindle index check bar and index dial, the main shaft point
Degree check bar is locked on index dial through index dial and using fixation member.
As a further solution of the present invention: fixation member includes bolt and lock nut, bolt is pacified by screw thread
In locking nut.
As a further solution of the present invention: bolt uses stud, connectivity robustness is good.
As a further solution of the present invention: the length and width of index dial is 100mm, index dial with a thickness of
15mm。
As a further solution of the present invention: spindle index check bar is Step Shaft.
Compared with prior art, the utility model has the beneficial effects that this product design is rationally, structure is simple, adjustment side
Just quickly, the adjustment capability at technique scene is increased；The variation of angle is converted to length variation to measure inspection by this product
It tests, detection time is short and easy to detect, is easily mastered, and it is low in cost, it can meet the requirements and effect can be used with save the cost
Fruit is good.

Specific embodiment
The technical solution of the patent is explained in further detail With reference to embodiment.
Embodiment 1
A kind of adjustable rotary shaft positioning accuracy detecting tool, including spindle index check bar 1 and index dial 2, the main shaft
Indexing check bar 1 is locked on index dial 2 through index dial 2 and using fixation member.Fixation member includes bolt 4 and locking screw
Mother 3, bolt 4 is by being threadably mounted in locking nut 3.Bolt 4 uses stud, and connectivity robustness is good.
Embodiment 2
A kind of adjustable rotary shaft positioning accuracy detecting tool, including spindle index check bar 1 and index dial 2, the main shaft
Indexing check bar 1 is locked on index dial 2 through index dial 2 and using fixation member.The length and width of index dial 2 is
100mm, index dial 2 with a thickness of 15mm.Spindle index check bar 1 is Step Shaft.
The working principle of the utility model is: spindle index check bar 1 is mounted in index dial 2, examined by spindle index
The product is mounted on main shaft by stick 1.Spindle index check bar 1 can make different main shafts by the spindle taper of different lathes
Check bar 1 is indexed, exchange is can be convenient in this way and is coupled with index dial 2, reach the main spindle's precision for examining different lathes.
The variation of angle is converted to length variation and examined to measure by the product, and application method is as follows: step 1,
The product is attached on main shaft, main shaft is switched to mode position, by using dial gauge by a side of square plate be adjusted to 1 with
It is interior, using this side as 0 degree of benchmark；Step 2, CNC system send instruction and are rotated by 90 °, and current actual value is measured using dial gauge；
Step 3, CNC system are sent instruction rotation 180 degree, current actual value are measured using dial gauge；Step 4, CNC system are sent
270 degree of instruction rotation, current actual value is measured using dial gauge；Step 5 records detected value, just the variation of angular error
Conversion is shown in Tables 1 and 2 for length variation.
Table 1 rotates clockwise 90 degree
Table 2 is rotated by 90 ° against needle
Positioning accuracy: α=0.435/100 atg=0.235X60X60=846 second
