Abstract

The utility model discloses a coaxiality detection tool, comprising a detection sleeve component and a detection bar. The detection sleeve component comprises a bottom plate and a cover plate which are sleeved on the detection bar, and a three-jaw chuck mechanism disposed between the bottom plate and the cover plate. The three-jaw chuck mechanism comprises a threaded knob and three jaws, the three jaws are all in threaded connection with the threaded knob, and make coaxial and equidistant telescopic motion under the effect of thread driving, and the tail ends of the three jaws are at the same circle. A dial indicator is disposed on the detection bar. The detection sleeve component in the utility model can move axially along the detection bar to select a measuring point, and the detection sleeve component can be guaranteed to match with the diameter of a measured hole without a gap at all time; and since the detection bar and the detection sleeve component are always coaxial, when the measurement of coaxiality is realized by comparing the detection bar and a reference axis, errors in measurement results are small.

Description

The right alignment cubing
Technical field
The utility model relates to a kind of cubing, relates in particular to a kind of right alignment cubing, is used to detect the right alignment of casing, housing endoporus.
Background technology
Right alignment is casing, the common requirement of housing endoporus, also is its main performance.It generally is to adopt inspection cover inspection rod to detect that the right alignment of casing or housing endoporus detects, but existing inspection cover inspection rod receives limited aperture and accuracy limitations in testing process, and error ratio is bigger; Certainly, the right alignment appearance, tracker, the three-dimensional coordinates measurement instrument that adopt high investment are arranged also, this type equipment cost is than higher.
The utility model content
The purpose of the utility model is to provide a kind of right alignment cubing, to solve the bigger problem of the inspection cover excellent error ratio of inspection of the prior art.
To achieve these goals, the technical scheme of the utility model is following:
The right alignment cubing is characterized in that, comprises inspection grip assembly and inspection rod; Said inspection grip assembly comprise be sleeved on inspection on the rod base plate, cover plate and be arranged on base plate and cover plate between scroll chuck formula mechanism; Said scroll chuck formula mechanism comprises screw knob and three claws, and three claws all are threaded with screw knob, and three claws are made the stretching motion of coaxial equidistance under the effect of screw drive; And the end of three claws also is provided with clock gauge on the inspection rod on same circle.
In a preferred embodiment of the utility model, the outer face of said screw knob is provided with scale.
In a preferred embodiment of the utility model, said inspection grip assembly has two groups, is arranged at interval on the inspection rod.
The utility model inspection grip assembly can move axially along the inspection rod and choose measurement point; And can guarantee to examine grip assembly cooperates in the crack with tested aperture all the time continuously; Coaxial all the time because of examining rod with the inspection grip assembly, relatively realize the measurement of right alignment by examining rod and reference axis, measuring result error is little.
The utility model contacts with tested aperture the time through terminal 3 of three claws of inspection grip assembly, can carry out the hi-Fix in this axle center, aperture.
Three claws of the utility model are made coaxial equidistance and are moved through the screw knob minute adjustment; The inspection grip assembly cooperates with the high precision of inspection rod makes the inspection rod coaxial all the time with the inspection grip assembly, all is to reduce measuring error, improves the effective measures of measuring accuracy.
The utility model passes through the equidistance expansion of three claws or stretches, and makes itself and tested aperture not have the gap all the time and cooperates, and has got rid of the gap error that the measurement of traditional inspection rod is brought.
The characteristics of the utility model can consult this case graphic and below better embodiment detailed description and obtain to be well understood to.
Description of drawings
Fig. 1 is the diagrammatic cross-section in the utility model use.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, further set forth the utility model below in conjunction with specific embodiment.
As shown in Figure 1, the right alignment cubing comprises inspection grip assembly and inspection rod 100, and the inspection grip assembly is sleeved on the inspection rod 100, and can move along inspection rod 100 and choose measurement point.The inspection grip assembly has two groups, is arranged at interval on the inspection rod 100.And can guarantee to examine grip assembly and cooperate in the crack continuously with tested aperture all the time, coaxial all the time because of examining rod with the inspection grip assembly, relatively realize the measurement of right alignment by examining rod and reference axis, measuring result error is little.
The inspection grip assembly comprises base plate 210, cover plate 220 and the scroll chuck formula mechanism 230 that is sleeved on the inspection rod, and scroll chuck formula mechanism 230 is arranged between base plate and the cover plate,
Scroll chuck formula mechanism comprises screw knob 231 and three claws 232, and the outer face of screw knob 231 is provided with scale, can measure diameter of bore.In the manufacturing process, assembling adjustment back reconditioning claw 232 guarantees with inspection rod 100 coaxial.
Three claws 232 all are threaded with screw knob 231, and three claws are made the stretching motion of coaxial equidistance under the effect of screw drive, and the end of three claws is on same circle.Terminal 3 of three claws contact with tested aperture the time, can carry out the hi-Fix in this axle center, aperture.
The other end of inspection rod is provided with clock gauge 300.
With the excellent endoporus of putting into tested part 400 of inspection grip assembly and inspection, rotate screw knob 231, through the screw thread transmission, three claws 232 are upheld, change and measure internal diameter, adjust the position; Rotation inspection rod 100 drives clock gauge 300 rotations, measures another hole circle degree, converts right alignment into.
More than show and described the advantage of ultimate principle, principal character and the utility model of the utility model.The technician of the industry should understand; The utility model is not restricted to the described embodiments; The just principle of describing in the foregoing description and the instructions of the utility model; The utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these variations and improvement all fall in the scope of the utility model that requires protection.The protection domain that the utility model requires is defined by appending claims and equivalent thereof.
