Description
Technical field
The utility model relates to survey instrument field, particularly relates to a kind of arc diameter instrument for quick measuring.
Background technology
In machining, often need the diameter measuring circular arc, because surveyed circular arc is not full circle, and often need to measure at the scene, existing measuring method has following shortcoming: 1, three-coordinates measuring machine speed is slow, and environmental requirement is high; 2, shape method measuring speed is thrown slow, low precision, cannot in-site measurement; 3, camber arc length calculating acquisition speed is slow.
Existing arc diameter detector can only be detected by Inner arc, but but can not detect according to external arc, and even damages because contact site hard makes piece surface scratch in testing process.
Utility model content
The technical matters that the utility model mainly solves is to provide a kind of arc diameter instrument for quick measuring.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: arc diameter instrument for quick measuring, comprise measurement instrument and measuring instrument body, described measurement instrument is arranged on described measuring instrument body central, described measurement instrument comprises table body, sleeve, sounding rod and measuring head, described sleeve is arranged on the lower end of described table body, and described sounding rod runs through described sleeve and described table body, and described sounding rod lower end is provided with measuring head;
Described measuring instrument body central offers connecting hole, and described connecting hole inwall lower end is provided with spacing ring, and described measuring instrument body two ends are provided with leg, and described leg top cover has protective sleeve.
In the utility model preferred embodiment, described measuring instrument body is inner circle arcuation.
In the utility model preferred embodiment, described measuring instrument body is cylindrical arcuation.
In the utility model preferred embodiment, the internal diameter of described spacing ring is greater than the external diameter of described sounding rod, and is less than the external diameter of described sleeve.
In the utility model preferred embodiment, the material of described measuring head and described protective sleeve is rubber.
The beneficial effects of the utility model are: the utility model arc diameter instrument for quick measuring; this arc diameter instrument for quick measuring adopts measuring instrument body to detect; by changing different measuring instrument bodies; not only can carry out detection diameter by the external arc of part; Inner arc also by part carries out detection diameter; make to detect more quick, on measuring instrument body two-end-point, cover has protective sleeve, make with can not wearing parts surface of contact during feature contacts.
Accompanying drawing explanation
The structural representation of Fig. 1 to be the utility model arc diameter instrument for quick measuring measuring instrument body be cylindrical arcuation.
The structural representation of Fig. 2 to be the utility model arc diameter instrument for quick measuring measuring instrument body be inner circle arcuation.
In accompanying drawing, the mark of each parts is as follows: 1, measurement instrument; 2, measuring instrument body; 3, body is shown; 4, sleeve; 5, sounding rod; 6, measuring head; 7, connecting hole; 8, spacing ring; 9, leg; 10, protective sleeve.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, to make advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus more explicit defining is made to protection domain of the present utility model.
Refer to Fig. 1 and Fig. 2, the utility model embodiment comprises: arc diameter instrument for quick measuring, comprise measurement instrument 1 and measuring instrument body 2, described measurement instrument 1 is arranged on described measuring instrument body 2 center, described measurement instrument 1 comprises table body 3, sleeve 4, sounding rod 5 and measuring head 6, reading display when described table body 3 is for detecting.
Described sleeve 4 is arranged on the lower end of described table body 3, installation when described sleeve 4 is connected with described measuring instrument body 2 for described measurement instrument 1 and location.
Described sounding rod 5 runs through described sleeve 4 and described table body 3, moving up and down thus detecting by described sounding rod 5.
Described sounding rod 5 lower end is provided with measuring head 6, and described measuring head 6 for contacting with arcwall face, thus detects.
Described measuring instrument body 2 center offers connecting hole 7, described connecting hole 7 inwall lower end is provided with spacing ring 8, the internal diameter of described spacing ring 8 is greater than the external diameter of described sounding rod 5, and be less than the external diameter of described sleeve 4, described spacing ring 8 coordinates with described sleeve 4, and described measurement instrument 1 is connected firmly with described measuring instrument body 2.
Described measuring instrument body 2 two ends are provided with leg 9, and described leg 9 top cover has protective sleeve 10, and leg 9 described in two for fixing with needing the circular arc of the part detected, thus is detected by the described sounding rod 5 of lifting.
Described measuring instrument body 2 is inner circle arcuation, surveys diameter for the external arc by part.
Described measuring instrument body 2 is cylindrical arcuation, surveys diameter for the Inner arc by part.
The material of described measuring head 6 and described protective sleeve 10 is rubber, make with during feature contacts can not part of damage surface.
Compared with prior art, the utility model arc diameter instrument for quick measuring, this arc diameter instrument for quick measuring adopts measuring instrument body to detect, by changing different measuring instrument bodies, not only can carry out detection diameter by the external arc of part, Inner arc also by part carries out detection diameter, make detection more quick, on measuring instrument body two-end-point, cover has protective sleeve, make with can not wearing parts surface of contact during feature contacts, during measurement, this measuring instrument is come on circular arc, reading numerical values is carried out by regulating dial gauge, considerably increase detection speed, detecting a part only needs just can complete a few second.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model instructions and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
