Abstract
The utility model relates to a gauge plate for testing the wall thickness of a pipe. A gauge groove is arranged at the right end of a planar plate body. An inner lower edge of the gauge groove is a straight edge, while the inner upper edge of the gauge groove is a stepped edge. The stepped edge includes a maximum wall thickness edge and a minimum wall thickness edge which are parallel to the lower edge. The gauge plate provided by the utility model is simple in structure and quick for tests.
Description
Technical field
The utility model relates to the inspection clamp of a kind of clamp, particularly tube wall thickness.
Background technology
In pipe finished inspection, dimension control is vital, and tube wall thickness need be tested by propping up on request.Generalized case tube wall thickness is to use milscale to measure, the every end of every arm is surveyed at 3 and is comprised maximal value, minimum value and intermediate value, thickness of steel pipe randomness is very large, not easy to operate in practice examining work, holding time is longer, especially speed of production is very fast, and the workshop that turnout is large will have a strong impact on the production storage of product if inspection speed does not catch up with.
Summary of the invention
In order to overcome the shortcoming of prior art, the utility model provides a kind of tube wall thickness inspection clamp, and it is simple in structure, and inspection speed is fast.
The technical scheme in the invention for solving the technical problem is: on the right-hand member of plane plate, have Card trough, the interior of Card trough is straight flange below, interior top is step limit, and there are thickest limit and minimal wall webbing in step limit, and thickest limit and minimal wall webbing are with described parallel below.
The utility model is simple in structure, and inspection speed is fast.
Brief description of the drawings
Below in conjunction with drawings and Examples, this utility model is further illustrated.
Fig. 1 is the utility model front view;
Fig. 2 is the utility model the first embodiment right view;
Fig. 3 is the utility model the second embodiment right view.
Embodiment
As shown in Figure 1, have Card trough 7 on the right-hand member of plane plate 2, interior following 4 of Card trough 7 is straight flange, and interior top is step limit, and there are thickest limit 1 and minimal wall webbing 3 in step limit, and thickest limit 1 and minimal wall webbing 3 are with described following 4 parallel.
The left part of described plane plate 2 has gain 5, conveniently dodges tested tubing end limit.
The left end of described plane plate 2 has Portable hole 6, is convenient for carrying, hangs.
The xsect of described following 4, thickest limit 1 and minimal wall webbing 3 is rectangle, as shown in Figure 2.
The xsect of described following 4, thickest limit 1 and minimal wall webbing 3 is arc, as shown in Figure 3.
The thick steel plate of material selection 6-8mm of the present utility model, preferably corrosion resistant plate, improves fastness to rubbing.Need to ensure that adequate thickness ensures indeformable, the method that uses line to cut is carried out the processing of measuring flume to ensure dimensional accuracy.
When use, Card trough 7 is snapped in to tubing along plain line direction, and circumferential slippage.If wall thickness is all the time between thickest limit 1 and minimal wall webbing 3, this pipe end wall thickness is qualified; Exceed the wall thickness upper limit as do not snapped in, exceed wall thickness maximal value, this pipe end wall thickness is defective; As snap in 3 of minimal wall webbings and exceed wall thickness lower limit, exceeding wall thickness minimum value, this pipe end wall thickness is defective.
Application notice: 1, need to use vernier caliper to measure draw-in groove size before use, prevent that every kind of specification is done several for subsequent use because the frequent abrasion size that uses becomes large more as far as possible.2, wall thickness readings as accurate in need need be used milscale.3, while measurement, should note observing whether there is obvious wall unevenness, need to use milscale to measure to determine whether to exceed eccentricity as existed.
