Abstract
The utility model discloses a portable detection instrument for a large-diameter inner bore. The portable detection instrument for the large-diameter inner bore is characterized by comprising an instrument stand, an instrument and a measuring bar, wherein the instrument is embedded in the instrument stand. The top ends of the instrument stand and the instrument are both provided with location bores, and the measuring bar is arranged in the location bores in embedded mode. The portable detection instrument for the large-diameter inner bore is capable of measuring a part with an inner bore which has a large diameter and adjusting range, simple in structure and convenient to operate.
Description
Technical field
The utility model belongs to the survey instrument field, relates to specifically a kind of portable larger diameter internal bore detection table.
Background technology
Existing measurer for detection of endoporus mainly contains: the vernier caliper of internal measuring micrometer, dial bore gage and a headband arc measuring head.It is the detection of 5 to 30 millimeters endoporus that internal measuring micrometer generally is used for diameter, because it is a bit of to be subjected to its structure influence, internal measuring micrometer can only measure the place, aperture.It is the detection of 10 to 100 millimeters endoporus that dial bore gage generally is used for diameter, but because its measuring head and sounding rod are complete sale, so cost is very high, and can only detect the less hole of interior diameter.The vernier caliper of one headband arc measuring head can be measured tens of or hundreds of millimeters the endoporus of diameter, but the precision of its detection is very low, and it is a bit of to detect the place, aperture, and the scope of measurement is restricted.
The utility model content
It is a kind of simple in structure, easy to operate that the purpose of this utility model is to provide, and the wide portable larger diameter internal bore of test specification detects table.
To achieve these goals, the utility model provides a kind of portable larger diameter internal bore detection table.It comprises instrument calibration, is embedded at instrument and sounding rod in the instrument calibration.The top of instrument calibration and instrument is equipped with pilot hole.Sounding rod is embedded in the pilot hole.
In some embodiments, also comprise increasing the journey bar, increase the journey bar and be embedded in the pilot hole, increase the journey bar and be connected by chuck with sounding rod, can regulate the range of endoporus detection table by increasing the journey bar.
In some embodiments, described instrument calibration is symmetric body, and described pilot hole is located on the symcenter of instrument calibration and instrument, and described instrument calibration lower end is provided with the spring column of two symmetries, the measuring head of instrument can be positioned on the diameter of tested gaging hole, be the diameter in hole with the detected value of guaranteeing instrument.。
In some embodiments, described instrument is fixed on the instrument calibration by pressing plate, and by screw fastening, makes the stationarity of instrument better.
In some embodiments, described instrument is dial gauge.
In some embodiments, the measuring head of described dial gauge, spring column and sounding rod are on same central plane.
In some embodiments, the back side of described instrument calibration is parallel with the central plane of the measuring head of dial gauge, is convenient for measuring and can improves the precision of measurement.
The utility model advantage compared to existing technology is: it is simple, easy to operate that the portable larger diameter internal bore described in this programme detects list structure, and can regulate the range of endoporus detection table by increasing the journey bar, makes measurement range wider.
Description of drawings
Fig. 1 is the structural representation of the portable larger diameter internal bore detection table of the utility model one embodiment;
Fig. 2 is the exploded perspective view of the portable larger diameter internal bore detection table of the utility model one embodiment.
Embodiment
Below in conjunction with drawings and the specific embodiments the utility model one embodiment is made further description explanation.
Portable larger diameter internal bore as depicted in figs. 1 and 2 detects table.It comprises instrument calibration 1, is embedded at instrument 2 and sounding rod 3 in the instrument calibration 1, also comprises increasing journey bar 4.
The top of instrument calibration 1 and instrument 2 is equipped with pilot hole 101.Instrument calibration 1 is symmetric body, and pilot hole 101 is located on the symcenter of instrument calibration 1 and instrument 2, and instrument calibration 1 lower end is provided with the spring column 102 of two symmetries.
Increasing journey bar 4 and also can be embedded in the pilot hole 101, also is by the screw 6 fastening positions that increase journey bar 4.Increase journey bar 4 and sounding rod 3 by being connected by chuck 5, can regulate the range of endoporus detection table by increasing journey bar 4.
When detecting, part to be detected can be placed on the one flat plate, the back side and the flat board of instrument calibration 1 is adjacent to, so just can measure very easily the hole interior diameter of part to be detected.And measuring accuracy is also higher.
The measurement initial value of portable larger diameter internal bore detection table described in the utility model is 85 millimeters, and the user can according to the extension of the size adjustment sounding rod 3 of diameter of bore, perhaps change the sounding rod 3 of different length.When it is measured length and does not also satisfy the testing requirement of hole interior diameter, can by chuck 201 with sounding rod 3 with increase journey bar 4 and couple together, reach the purpose of increase range.
It is simple, easy to operate that portable larger diameter internal bore described in this programme detects list structure, and can regulate the range of endoporus detection table by increasing the journey bar, makes measurement range wider.
Above-described only is optimal way of the present utility model; should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the utility model creation design; can also make some distortion and improvement, these also should be considered as within the protection domain of the present utility model.
