Abstract
The invention discloses a portable large-diameter inner hole detecting instrument. The portable large-diameter inner hole detecting instrument is characterized in that the portable large-diameter inner hole detecting instrument comprises an instrument stand, an instrument and a measuring rod, wherein the instrument and the measuring rod are arranged in the instrument stand in an embedded mode, locating holes are formed in both the top end of the instrument stand and the top end of the instrument, and the measuring rod is arranged in the locating holes in an embedded mode. The portable large-diameter inner hole detecting instrument can measure parts with large-diameter inner holes, the size of measuring ranges can be adjusted, and the portable large-diameter inner hole detecting instrument is simple in structure and convenient to operate.
Description
Technical field
The invention belongs to survey instrument field, relate to specifically a kind of portable larger diameter internal bore detection table.
Background technology
The existing measurer for detection of endoporus mainly contains: the vernier caliper of internal measuring micrometer, dial bore gage and a headband arc measuring head.Internal measuring micrometer is generally used for the detection that diameter is 5 to 30 millimeters of endoporus, and owing to being subject to its structure influence, it is a bit of that internal measuring micrometer can only be measured place, aperture.Dial bore gage is generally used for the detection that diameter is 10 to 100 millimeters of endoporus, but because its measuring head and sounding rod are complete sale, so cost is very high, and can only detect the hole that interior diameter is less.The vernier caliper of one headband arc measuring head can be measured the tens of or endoporus of hundreds of millimeters of diameter, but the precision of its detection is very low, can only detect place, aperture a bit of, and the scope of measurement is restricted.
Summary of the invention
The object of the present invention is to provide a kind of simple in structurely, easy to operate, and the wide portable larger diameter internal bore of test specification detects table.
To achieve these goals, the invention provides a kind of portable larger diameter internal bore detection table.It comprises instrument calibration, is embedded at instrument and sounding rod in instrument calibration.The top of instrument calibration and instrument is equipped with pilot hole.Sounding rod is embedded in pilot hole.
In some embodiments, also comprise and increase journey bar, increase journey bar and be embedded in pilot hole, increase journey bar and be connected by chuck with sounding rod, by increasing journey bar, can regulate the range of endoporus detection table.
In some embodiments, described instrument calibration is symmetric body, and described pilot hole is located in the symcenter of instrument calibration and instrument, and described instrument calibration lower end is provided with two symmetrical spring columns, the measuring head of instrument can be positioned on the diameter of tested gaging hole, to guarantee that the detected value of instrument is the diameter in hole.。
In some embodiments, described instrument is fixed on 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 measuring.
The present invention's advantage is compared to existing technology: it is simple, easy to operate that the portable larger diameter internal bore described in this programme detects list structure, and by increasing journey bar, can regulate the range of endoporus detection table, makes measurement range wider.
Accompanying drawing explanation
Fig. 1 is the structural representation of the portable larger diameter internal bore detection table of an embodiment of the present invention;
Fig. 2 is the exploded perspective view of the portable larger diameter internal bore detection table of an embodiment of the present invention.
Embodiment
Below in conjunction with drawings and the specific embodiments, an embodiment of the present invention is made to 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 instrument calibration 1, also comprises and increases 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 in the symcenter of instrument calibration 1 and instrument 2, and instrument calibration 1 lower end is provided with two symmetrical spring columns 102.
Increasing journey bar 4 and also can be embedded in pilot hole 101, is also by the position of the fastening increasing journey of screw 6 bar 4.Increasing journey bar 4 by being connected by chuck 5, can regulate the range of endoporus detection table with sounding rod 3 by increasing journey bar 4.
When detecting, part to be detected can be placed on one flat plate, the back side of instrument calibration 1 and flat board are 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 of the present invention is 85 millimeters, and user can be according to the extension of the size adjustment sounding rod 3 of diameter of bore, or changes the sounding rod 3 of different length.When its measurement length also can not meet the testing requirement of hole interior diameter, can sounding rod 3 and increasing journey bar 4 be coupled together by chuck 201, reach the object that increases range.
It is simple, easy to operate that portable larger diameter internal bore described in this programme detects list structure, and by increasing journey bar, can regulate the range of endoporus detection table, makes measurement range wider.
Above-described is only optimal way of the present invention, it should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise of the invention, can also make some distortion and improvement, within these also should be considered as protection scope of the present invention.
