Abstract

The utility model provides a measurement tool for shafting alignment. The tool comprises a flange hole base, a fastening nut, a support bar, a moving bar, a fastening screw, a vertical dial indicator, and a transverse dial indicator. The support bar is in threaded connection with a fastening bolt through the flange hole base, and the fastening screw fastens the support bar to a shafting flange. The vertical dial indicator and the transverse dial indicator are fixed on the support bar and the moving bar respectively. Plungers of the dial indicators are in contact with an outer circumferential surface and the back (or front) surface of a to-be-measured shafting flange. The shafting offset and angularity can be obtained directly from readings of the dial indicators through rotation of the shafting flange, and thus manual measurement errors are reduced. The tool is simple in structure, easy to produce and operate, and high in measurement precision. The tool has no technical requirements for operators, and can be widely applied to measurement of shafting alignment of ships and mechanical engineering.

Traditional centering of shafting generally adopts skew and the complications of measuring coupling of shaft system flange to carry out in school.In this school, have two kinds of methods, a kind of is to use white steel knife to coordinate clearance gauge to measure the off-set value of joint flange, measures the complications value of flange binding face with clearance gauge.Another kind is to adopt frock to set up dial gauge to survey flange excircle, with clearance gauge, measures tortuous value.These two kinds of measuring methods are very practical, but manual operation is more, and measuring point amount is large, easily cause error and precision not high.
Summary of the invention
Technical problem to be solved in the utility model is the shortcoming for traditional centering of shafting measuring method workload is large, precision is not high, the frock that provides a kind of centering of shafting to measure, this device can be widely used in the centering of shafting of boats and ships, mechanical engineering etc., simple to operate, precision is high and direct survey measurements.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of centering of shafting is measured frock, comprise flange hole base, support bar, jackscrew, vertical dial gauge, motion bar and horizontal dial gauge, described support bar is connected with flange hole whorl of base by the first fastening bolt, and it is on flange that jackscrew is fixed on axle through support bar by support bar;
Vertical dial gauge is fixed on vertical dial gauge on support bar by vertical dial gauge jackscrew, and vertical dial gauge thimble and axle are the laminating of flange outer marginal circumference face;
Laterally dial gauge is fixed on horizontal dial gauge on motion bar by horizontal dial gauge jackscrew, and laterally dial gauge thimble and axle are the flange back side or positive laminating;
Motion bar is threaded with support bar by the second fastening bolt.
Described flange hole base is right cylinder, and cylinder diameter is that flange aperture is identical with axle, and it is in flange hole that flange hole base is placed in axle, and flange hole base one end is provided with threaded hole.
Described support bar is inverted "L" shaped, and left arm is provided with the threaded hole being connected with flange hole base, and support bar upper arm is provided with several bolts hole and T-shape hole, in the upright opening in T-shape hole, is provided with screw thread.
The described axis of the first fastening bolt and the axis of jackscrew are vertical.
Support bar is provided with several bolts hole, and described motion bar is connected with the second fastening bolt that passes the bolt hole on support bar.
A kind of centering of shafting that the utility model provides is measured frock, by rotary axis flange, reads off-set value and the tortuous value that dial gauge reading can directly obtain shaft system, reduces manual measurement error.The utility model is simple in structure, simple for production, convenient to operation, and measuring accuracy is high, and operating personnel, without technical requirement, can be widely used in marine shafting and mechanical engineering centering of shafting and be measured.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail:
Fig. 1 is that the utility model structural representation and measurement axle are off-set value and tortuous value schematic diagram.
Fig. 2 is that the utility model measurement clearance axle is off-set value and tortuous value schematic diagram.
In Fig. 1-2: axle is flange 1, the first fastening bolt 2, flange hole base 3, support bar 4, jackscrew 5, vertical dial gauge 6, motion bar 7, laterally dial gauge 8, vertically dial gauge jackscrew 9, laterally dial gauge jackscrew 10, the second fastening bolts 11.
Embodiment
In Fig. 1,2, a kind of centering of shafting is measured frock, comprise flange hole base 3, support bar 4, jackscrew 5, vertical dial gauge 6, motion bar 7 and horizontal dial gauge 8, support bar 4 is threaded with flange hole base 3 by the first fastening bolt 2, and it is on flange 1 that jackscrew 5 is fixed on axle through support bar 4 by support bar 4;
Vertical dial gauge 6 is fixed on vertical dial gauge 6 on support bar 4 by vertical dial gauge jackscrew 9, and vertical dial gauge 6 thimbles and axle are flange 1 outer marginal circumference face laminating;
Laterally dial gauge 8 is fixed on horizontal dial gauge 8 on motion bar 7 by horizontal dial gauge jackscrew 10, and laterally dial gauge 8 thimbles and axle are flange 1 back side or positive laminating;
Motion bar 7 is threaded with support bar 4 by the second fastening bolt 11.
Structure, can measure the error between axle system easily by vertical dial gauge 6 and horizontal dial gauge 8 thus.By the first fastening bolt 2, be connected with flange hole whorl of base, it is on flange 1 that jackscrew 5 is fixed on axle by the support bar of " L " type, guaranteed that on support bar 4, vertical dial gauge can be fitted with flange outer marginal circumference face and the back side respectively with horizontal dial gauge thimble, directly rotary flange is measured, and while measuring without separately establishing reference point, directly meter reading.
Described flange hole base 3 is right cylinder, and cylinder diameter is that flange 1 aperture is identical with axle, and it is in flange hole that flange hole base 3 is placed in axle, and flange hole base 3 one end are provided with threaded hole.Flange hole base 3 is placed in the flange hole that axle is flange 1, tightens jackscrew 5 and can fix easily whole support bar 4, thereby measure the installation site of axle system.
