Abstract
The utility model discloses an inside diameter measurement instrument relates to the industrial products production field. Including scale rod and slide bar, scale rod's upper end surface indicates different radial conversion scales, and the slide bar cup joints the surface at scale rod, sliding connection between the two, scale rod bottom fixed mounting has a columniform base, and three measuring sticks are evenly connected through the pivot to the circumference outside face of base, and a contact ball is all installed to the other end of every measuring stick, the bottom of slide bar evenly is connected with three traction levers through the pivot, and every traction lever links to each other through an universal ball and a measuring stick. The beneficial effects of the utility model are that: use the utility model discloses internal diameter that can the great size work piece of accurate measurement can realize that flange work piece and opening are less simultaneously, the inside diameter measurement of the great work piece of internal diameter, and operation process is simple and convenient, and measurement accuracy is higher, can realize industrial production's measurement requirement basically.
Description
Technical field
The utility model relates to industrial products production field.
Background technology
In the processing of boiler, petroleum refining equipment and the equipment such as pharmacy and chemical industry, often need measure large-sized pipe fitting interior diameter.Existing inside-diameter measuring tool has the multiple survey instruments such as clamp, vernier caliper, milscale, these survey instruments are all measure less instrument, and adopt Steel Ruler or steel tape to measure, not only precision is low but also efficiency is low, simultaneously less for opening, the workpiece that internal diameter is larger, is difficult to realize the measurement to internal diameter.
Utility model content
Technical problem to be solved in the utility model is the technical deficiency for above-mentioned existence, provides a kind of inside-diameter measuring tool.Use the utility model can the internal diameter of Measurement accuracy large-size workpiece, simultaneously can realize flange workpiece and opening less, the inner diameter measurement of the larger workpiece of internal diameter, operating process is simple and convenient, measuring accuracy is higher, substantially can realize industrial measurement requirement.
The technical solution adopted in the utility model is: provide a kind of inside-diameter measuring tool, comprises scale bar and sliding bar, and the upper end outside surface of scale bar indicates the conversion scale of different radii, and sliding bar is socketed in the outside surface of scale bar, is slidably connected between the two; Scale bar bottom fixedly mounts a columniform base, and outside the circumference of base, face evenly connects three sounding rods by rotating shaft, and the other end of every root sounding rod is all provided with a contact ball; The bottom of sliding bar is evenly connected with three towbars by rotating shaft, and every root towbar is connected with a sounding rod by a multi-directional ball.
Further optimization the technical program, the top of the scale bar of inside-diameter measuring tool fixedly mounts a limiting stand.
Further optimization the technical program, the sliding bar of inside-diameter measuring tool be circumferentially evenly provided with three with the spacing hole contacting ball and coordinate.
Further optimization the technical program, the contact ball of inside-diameter measuring tool adopts hard material.
The utility model is compared with traditional measurement instrument, its beneficial effect is: 1, use the utility model can the internal diameter of Measurement accuracy large-size workpiece, simultaneously can realize flange workpiece and opening less, the inner diameter measurement of the larger workpiece of internal diameter, operating process is simple and convenient, measuring accuracy is higher, substantially can realize industrial measurement requirement; 2, limiting stand can play limit slippage bar excessive slip, avoids the wearing and tearing of scale bar high scale, avoids the undue stretching to towbar and sounding rod simultaneously, improves serviceable life of the present utility model; 3, at the utility model when not using, spacing hole can make three contact balls be placed in respectively in spacing hole, conveniently deposit; 4, contacting ball adopts hard material to improve measuring accuracy, avoids the excessive wear contacting ball, increases the service life.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure, 1, scale bar; 2, sliding bar; 3, base; 4, sounding rod; 5, ball is contacted; 6, towbar; 7, multi-directional ball; 8, limiting stand; 9, spacing hole.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, inside-diameter measuring tool comprises scale bar 1 and sliding bar 2, and the upper end outside surface of scale bar 1 indicates the conversion scale of different radii, and sliding bar 2 is socketed in the outside surface of scale bar 1, is slidably connected between the two; Scale bar 1 bottom is installed with a columniform base 3, and outside the circumference of base 3, face evenly connects three sounding rods 4 by rotating shaft, and the other end of every root sounding rod 4 is all provided with a contact ball 5; The bottom of sliding bar 2 is evenly connected with three towbars 6 by rotating shaft, and every root towbar 6 is connected with a sounding rod 4 by a multi-directional ball 7; The top of scale bar 1 fixedly mounts a limiting stand 8; Sliding bar 2 be circumferentially evenly provided with three with the spacing hole 9 contacting ball and coordinate.
During use, sounding rod 4 of the present utility model is extend into the inside of the workpiece that will measure, one holds limiting stand 8, one holds sliding bar 2, and sounding rod 4 launches by slide downward sliding bar 2, sliding ball 5 on sounding rod 4 is skidded off in spacing hole 9, and contact fully with the interior surface of workpiece, writing down the scale number of degrees on now scale bar 1, is exactly the internal diameter of workpiece.When measurement completes, upwards pull sliding bar 2, sounding rod 4 is packed up, and the contact ball 5 on sounding rod 4 is returned in spacing hole 9, taken out from inside workpiece by the utility model, measurement completes.
