Abstract
The utility model discloses a groove depth measuring instrument. The groove depth measuring instrument comprises a dial gauge, wherein the dial gauge comprises a gauge body, a measuring rod, a measuring rod supporting tube, an upper base sleeve and a lower supporting base, wherein the top of the upper base sleeve is fixed with the dial gauge; the measuring rod and the measuring rod supporting tube of the dial gauge are arranged inside the upper base sleeve; the bottom of the upper base sleeve is connected with the lower supporting base; a core hole is formed in the axial direction of the lower supporting base; the core hole penetrates through the lower supporting base; a core rod is arranged inside the core hole; a pressing block is fixed on the upper end part of the core rod; a probe is inserted into the lower end part of the core rod; in the upper base sleeve, the end part of the measuring rod of the dial gauge is contacted with the upper surface of the pressing block; a spring base is arranged on the pressing block; and a spring is arranged inside the spring base. The groove depth measuring instrument is ingenious in structure and reasonable in design and can measure the depth of a groove directly; and measured data is accurate.
Description
Technical field
The utility model relates to a kind of length measuring instrument, and a kind of instrument of measuring depth of groove of more specifically saying so belongs to the surveying instrument technical field.
Background technology
In the processing of some metals, the processing of the oil pipe that connects as attaching type need be at the surface working groove of pipe, and the degree of depth of groove need be than higher precision, and all is difficult to direct measurement as the dimensional measuring instrument of routines such as dial gauge, vernier caliper.
The utility model content
At above-mentioned situation, when the problem that the utility model quasi-solution is determined provides a kind of machined grooves or shrinkage pool, can directly measure the instrument of depth of groove.
For achieving the above object, the utility model has adopted following technical scheme: a kind of depth of groove measuring instrument, it comprises dial gauge, described dial gauge comprises table body, sounding rod and sounding rod stay pipe, it also comprises cover for seat and undersetting, described top and the dial gauge of going up cover for seat fixed, and the sounding rod of dial gauge and sounding rod stay pipe be in last cover for seat, and the bottom of last cover for seat is connected with undersetting; Undersetting be axially arranged with the core hole, undersetting is run through in described core hole, described core hole is provided with core bar, the upper end of described core bar fixedly briquetting, bottom is installed with probe; Described going up in the cover for seat, the sounding rod end of dial gauge contacts with the briquetting upper surface, and described briquetting is provided with spring base, and described spring base is equipped with spring.
Described top of going up cover for seat is fixed as with dial gauge: the described seat of honour puts and is provided with and the vertical screw rod of seat of honour cover axis, and described screw rod passes seat of honour jacket wall, and its end is tight against on the sounding rod stay pipe of dial gauge.Described bottom of going up cover for seat is connected to undersetting and is threaded.The length that described probe passes the core bar bottom is 3-8 centimetre.
Adopt such scheme, depth of groove measuring instrument of the present utility model, because it is certain that probe passes the length of bottom (undersetting bottom) of core bar, suppose that its extension elongation is L, and L must be greater than the degree of depth M of groove or shrinkage pool, during measurement the dial gauge reading is set to zero or write down the dial gauge initial reading, the undersetting bottom of depth of groove measuring instrument touches on the measured object then, its probe penetrates in groove or the shrinkage pool, because the top probe is gone up in groove or shrinkage pool bottom, core bar is overcome in the core hole on the elastic force of spring to be moved, dial gauge sounding rod in top on the briquetting then, the reading of dial gauge is changed, and at this moment, the reading variable quantity of L-dial gauge is the degree of depth M of groove or shrinkage pool.As can be seen from the above analysis, depth of groove measuring instrument structure of the present utility model is ingenious, reasonable in design, can directly measure depth of groove, and to survey data accurate.
