Abstract
The utility model relates to a wide-range inner diameter measurement dial indicator, which comprises a dial indicator head (1), a measuring head (6) and a measuring bar (7) and is characterized by also comprising at least one extension bar (3), wherein one end of the extension bar (3) is connected with the dial indicator head (1), and the other end of the extension bar (3) is connected with the measuring head (6). The utility model relates to the wide-range inner diameter measurement dial indicator.
Description
[technical field]
The utility model relates to feeler-pin gauge, refers to a kind of wide range inner diameter measurement dial gauge especially.
[background technology]
In the manufacturing of 02 machinery, maintenance, testing, often to accurately measure the internal diameter of launching tube, or situations such as its wearing and tearing, expansion and distortion.Because rocket-launching battery belongs to slender body, conventional not competent this work of dial bore gage.
[summary of the invention]
At the shortcoming of prior art, the purpose of this utility model is to provide a kind of wide range inner diameter measurement dial gauge.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of wide range inner diameter measurement dial gauge, include percentage gauge outfit, measuring head and gauge rod, and it is characterized in that; Also include at least one extension bar, described extension bar one end is connected with the percentage gauge outfit, and the other end is connected with measuring head.
Described connection can be adopted and be threaded.
Described extension bar can be one or two.
Using method:, this measuring head and extension bar (adorning one or two according to the needs that fathom) and dial gauge are connected and fixed with wiped clean in the launching tube.Choose the extension bar of suitable length according to bore, be contained on the measuring head, on vernier caliper (or percentage card), fix the standard size of bore again, and it is stuck on the gauge rod of measuring head.Extension bar is parallel with axially bored line during measurement, slightly swing extension bar then up and down, minimum value shown in watching on the dial gauge, its value adds the standard size using method of bore: with wiped clean in the launching tube, the measuring head of this instrument and extension bar (adorning one or two according to the needs that fathom) and dial gauge Antu are linked up, and with nut with revolve spiral shell and fix.Choose the gauge rod of suitable length according to bore, be contained on the measuring head, on vernier caliper (or percentage card), fix the standard size of bore again, and, the dial gauge upright position measured once its gauge rod that is stuck in measuring head.Extension bar is parallel with axially bored line during measurement, slightly swings extension bar then up and down, the minimum value shown in watching on the dial gauge, and its value adds that the standard size of bore is the bore of surveying.
The beneficial effects of the utility model are: can accurately measure the internal diameter of slender body, be specially adapted to the measurement of rocket-launching battery internal diameter.
[description of drawings]
The utility model will be further described below in conjunction with accompanying drawing.
Accompanying drawing is a structural representation of the present utility model;
Among the figure: 1 is that percentage gauge outfit, 2 is that nut, 3 is that extension bar, 4 is that groove, 5 is that measuring head, 7 is a gauge rod for revolving spiral shell, 6.
[embodiment]
Referring to accompanying drawing, a kind of wide range inner diameter measurement of the utility model dial gauge includes percentage gauge outfit 1, measuring head 6 and gauge rod 7, it is characterized in that; Also comprise at least one extension bar 3, described extension bar 3 one ends are connected with percentage gauge outfit 1, and the other end is connected with measuring head 6.
In embodiment of the present utility model, described extension bar 3 one ends are connected with percentage gauge outfit 1 by nut 2, and the other end is connected with measuring head 6 by revolving spiral shell 4.
Claims (2)
