Description
Technical field
This utility model relates to graphite product processing technique field, is specifically related to a kind of dial gauge detecting the Small Holes degree of depth.
Background technology
Owing to graphite has many excellent performances, thus obtain extensive use at the industrial department such as metallurgical, mechanical, electric, chemical industry, weaving, national defence.Refractory material can be made.Graphite product maintains the original chemical characteristic of crystalline flake graphite and also has very strong self-lubricating property.The characteristic of graphite powder and high-strength acid resistance, anticorrosive and high temperature resistant 3000 DEG C and low temperature resistant-204 DEG C, its comprcssive strength is more than 800kg/Cm2 simultaneously, and antioxidation, and in 450 DEG C of air weightless 1%, rebound degree is 15-50%(density 1.1-1.5).Therefore graphite product has now been widely used in metallurgy, chemical industry, petrochemical industry, high-energy physics, space flight, electronics etc..
In the course of processing of various graphite product, many graphite products needs according to function, positions different on goods offers a lot of aperture, these apertures often degree of depth differs, and diameter is minimum, the degree of depth accurately of giving vent to anger cannot be measured, for instance although slide gauge has the function of the measured hole degree of depth, but its measurement shank diameter is excessive and limited precision with conventional survey tool；Its end measuring bar of common dial gauge is a bead, and its diameter is excessive cannot play a role in the depth survey in minimum hole, graphite product surface.
Utility model content
In view of this, the purpose of this utility model is in that to provide a kind of dial gauge detecting the Small Holes degree of depth, measurement boom end bead replaces to thin bar on the basis of common dial gauge table body, and adopts the adjustment seat of partition type to strengthen its adaptability.
The technical scheme adopted for realizing the purpose of this utility model is: a kind of dial gauge detecting the Small Holes degree of depth, it is characterized in that, including table body, adjust seat, locking nut, it is provided with sleeve on the downside of described table body, measurement bar it is provided with in described sleeve, described measurement bar runs through table body, described adjustment cover for seat is located at the outer surface of sleeve, it is protruding that the upper surface of described adjustment seat is provided with the sleeve-like coordinated with sleeve, the top of described projection is inclined-plane, the outer surface of described projection is provided with screw thread, the threaded engagement of described locking nut and convex outer surface, and the inner surface of locking nut is provided with the wedge surface coordinated with convex top inclined-plane.
Further, the bottom of described measurement bar is thin bar.
Further, described projection even partition vertically.
The beneficial effects of the utility model:
A kind of dial gauge detecting the Small Holes degree of depth that this utility model provides, by being arranged to thin bar by the end measuring bar so that dial gauge can meet the measurement of the Small Holes degree of depth；Coordinated by the inclined-plane of the wedge surface on locking nut with protruding end, when moving up and down in the threaded engagement of locking nut and convex outer surface, under interaction between wedge surface and inclined-plane, the projection of partition type can be combined closely with sleeve better, improves certainty of measurement.
Accompanying drawing explanation
Fig. 1 is the structural representation of the dial gauge of the detected Small Holes degree of depth that this utility model provides；
Fig. 2 is the top view adjusting seat.
Detailed description of the invention
Below by specific embodiment and in conjunction with accompanying drawing, this utility model is described in further detail.
Fig. 1 illustrates a kind of dial gauge detecting the Small Holes degree of depth that this utility model provides, including table body 7, adjust seat 5, locking nut 3, sleeve 2 it is provided with on the downside of table body 7, measurement bar 1 it is provided with in sleeve 2, measure bar 1 and run through table body 7, adjust seat 5 and be set in the outer surface of sleeve 2, as in figure 2 it is shown, the upper surface 6 adjusting seat 5 is provided with the sleeve-like projection 11 coordinated with sleeve 2；The top of protruding 11 is inclined-plane 10, and the outer surface of protruding 11 is provided with screw thread 4, and the screw thread 4 of locking nut and 3 protruding 11 outer surfaces coordinates and the inner surface of locking nut 3 is provided with the wedge surface 9 coordinated with protruding 11 top bevel 10.
Table body 7 is as broad as long with sleeve 2 part and common dial gauge, measures bar 1 in sleeve 2, and runs through table body 7, appear above table body 7, measuring appearing of bar 1, the round end 8 being provided with portable measurement bar.Adjusting the profile that seat 5 is a revolving body, the bottom surface adjusting seat 5 is a plane, adjusts the projection 11 of seat 5 upper surface in sleeve-like, and sleeve 2 is through adjusting seat 5, and before locking nut 3 is not locked, adjusting seat 5 can moving axially along sleeve 2；The bottom of locking nut 3 inner surface forms threaded engagement 4 with protruding 11 outer surfaces, above screw thread 4 on protruding 11, projection 11 is thinning gradually, namely an inclined-plane 10 is formed, inclined-plane 10 forms wedge surface with the wedge surface 9 on locking nut 3 and coordinates, and when locking nut 3 screws, wedge surface coordinates the pressure making projection 11 be subject to radial direction, thus locking sleeve 2, reach the purpose adjusting seat 5 with sleeve 2 locking.、
Further, the bottom measuring bar 1 is thin bar, when measuring the degree of depth of Small Holes, it is possible to the inside going deep into hole scratches without being formed on the inwall in hole.
As in figure 2 it is shown, projection 11 even partition vertically, in the present embodiment, protruding 11 are divided into three lobes so that the effect of locking nut 3 is more prone to realize.
The foregoing is only preferred embodiment of the present utility model, be not limited to this utility model, for a person skilled in the art, this utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment of making, equivalent replacement, improvement etc., should be included within protection domain of the present utility model.
