Abstract

The utility model discloses a quick measuring device of circular arc surface convex -concave value, including base and percentage table, the base both ends are equipped with the stabilizer blade, and base centre top is equipped with the percentage table mounting hole, and the axle sleeve bottom of percentage table is equipped with the external screw thread, and the axle sleeve of percentage table passes the percentage table mounting hole and fixes in the percentage table mounting hole through the nut. The utility model has the advantages of: also can the accurate measurement reinforcement under the condition that the welding seam was not planished completely, there is less pit also can measure to the circular arc surface, can go deep into simultaneously darker inside measurement of steel pipe, also the outside welding seam of measurable quantity steel pipe middle part, measurement operation is simple, the reading is convenient, its simple structure, and low in manufacturing cost, convenient to use easily promotes.

Description

Arc-shaped surface convex-concave value rapid measurement device
Technical field
The utility model relates to the measuring technique of steel pipe inner and outer welding reinforcement, refers to a kind of arc-shaped surface convex-concave value rapid measurement device particularly.
Background technology
The method of current measurement steel pipe seam reinforcement has following three: the first, and measure with supersonic thickness meter, its shortcoming cannot measure when weld seam detection face is unsmooth, or measured numerical value is inaccurate; The second, with miking, the method can only record port reinforcement, can not to measure in steel pipe comparatively deep location and steel pipe middle outside surface reinforcement, and complex operation; 3rd, measure with General welding detection ruler, the method is mainly for large-diameter steel pipe and butt plates welding seam, larger to small-caliber steel pipe error, as can be seen here, at present good method be there is no to steel pipe seam reinforcement, and the measurement at present for arc-shaped surface pit depth value do not have good way yet.
Summary of the invention
The purpose of this utility model will provide a kind of structure simple, easy to use exactly and measure arc-shaped surface convex-concave value rapid measurement device accurately.
For achieving the above object, arc-shaped surface convex-concave value rapid measurement device designed by the utility model, comprise base and dial gauge, it is characterized in that: described base two ends are provided with leg, top, described base center is provided with dial gauge mounting hole, the axle sleeve bottom of described dial gauge is provided with external thread, the axle sleeve upper end outer wall of described dial gauge is circumferentially provided with positive stop lug boss, the axle sleeve of described dial gauge passes dial gauge mounting hole and is fixed in dial gauge mounting hole by nut, described positive stop lug boss lower surface props up described base upper surface, the sounding rod be connected with the dial reading of dial gauge is provided with in the axle sleeve of described dial gauge, the bottom of described sounding rod is provided with measuring head, the length sum of described measuring head and sounding rod and the vertical length of leg match, thus two legs all can contact measured circular arc surface with measuring head under guaranteeing duty.
Further, described leg is crab claw shape, is arranged symmetrically in base two ends, convenient mobile during use.
Again further, the length of the sounding rod of described dial gauge is 40 ~ 120mm, and measurement range is wider.
The utility model has the advantage of: also can Measurement accuracy reinforcement when weld seam is not planished completely; There is less pit also can measure to arc-shaped surface; The darker internal measurement of steel pipe can be goed deep into simultaneously, also can measure the convex-concave point place at the outside any position of steel pipe; Measure simple to operate; Convenient reading, its structure is simple, and low cost of manufacture is easy to use, is easy to promote.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of arc-shaped surface convex-concave value rapid measurement device.
Fig. 2 and Fig. 3 is the operating diagram measuring the protruding value of exterior arc surface.
Fig. 4 and Fig. 5 is the operating diagram measuring the protruding value of inner arc surface.
Fig. 6 and Fig. 7 is the operating diagram measuring exterior arc surface pit depth.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
A kind of arc-shaped surface convex-concave value rapid measurement device, comprise base 1 and dial gauge 2, base 1 two ends are provided with leg 7, base 1 hits exactly top and is provided with dial gauge mounting hole 3, the axle sleeve bottom of dial gauge 2 is provided with external thread, the axle sleeve upper end outer wall of dial gauge 2 is circumferentially provided with positive stop lug boss 4, the axle sleeve of dial gauge 2 passes dial gauge mounting hole 3 and is fixed in dial gauge mounting hole 3 by nut 8, positive stop lug boss 4 lower surface props up described base 1 upper surface, the sounding rod 5 be connected with the dial reading of dial gauge 2 is provided with in the axle sleeve of dial gauge 2, the bottom of sounding rod 5 is provided with measuring head 6, the length sum of measuring head 6 and sounding rod 5 and the vertical length of leg 7 match, thus two legs 7 all can contact measured circular arc surface with measuring head 6 under guaranteeing duty, leg 7 is in crab claw shape, be arranged symmetrically in base 1 two ends, the length of the sounding rod of dial gauge 2 is 40 ~ 120mm.
When measuring exterior arc surface projection value, two legs 7 contact tested cambered surface (as shown in Figure 2), first make measuring head 6 contacting surface, record the reading a on dial plate, mobile two legs 7 again, make measuring head 6 contact projection face peak (as shown in Figure 3), record the reading b on dial plate, b deducts the numerical value that a obtains and is protruding value; Ensure in whole use procedure, the plane that two legs 7 and sounding rod 5 are formed is parallel with the sagittal plane of circular arc.Measure inner arc surface projection value (as described in Fig. 4, Fig. 5), measurement exterior arc surface pit depth (as shown in Figure 6, Figure 7) to be all worth in like manner with measurement exterior arc surface projection.Like this, also can Measurement accuracy reinforcement when weld seam is not planished completely; There is less pit also can measure to arc-shaped surface; The darker internal measurement of steel pipe can be goed deep into simultaneously, also can measure the convex-concave point place at the outside any position of steel pipe; Measure simple to operate; Convenient reading, its structure is simple, and low cost of manufacture is easy to use, is easy to promote.
