Abstract
The utility model discloses a pipe wall thickness measuring tool provided with a dial indicator. In the prior art, the pipe wall thickness is measured by a vernier caliper, the measurement precision is limited, the error accumulation may occur, and the thickness of a wall which is far away from an pipe mouth end face cannot be measured, the pipe wall thickness measuring tool can solve the above problems. The pipe wall thickness measuring tool includes a pedestal, a measuring rod, a support, and the dial indicator. The middle of the pedestal is horizontally fixed with the measuring rod. The end head of the measuring rod is fixed with a measuring ball. The support is arranged at a position above the middle part of the pedestal. The length of the support is equal to the length of the measuring rod. The end head of the support is provided with a through hole and a bolt which fix the dial indicator. The dial indicator is fixed on the end head of the support and the measuring head is coaxial with the measuring ball. The beneficial effects of the pipe wall thickness measuring tool provided with the dial indicator are that the precision is high, the reading is accurate, and the thickness of the pipe wall which is far away from the pipe mouth end face can be measured.
Description
Technical field
The utility model relates to a kind of tube wall survey instrument, specially refers to a kind of band table pipe thickness survey instrument.
Background technology
Prior art adopts the vernier caliper measurement pipe thickness usually, during measurement, perhaps adopts claw directly to be stuck in the tube wall place and measures, and the external diameter and the internal diameter that perhaps adopt claw to measure respectively pipe calculate wall thickness again.Because the measuring accuracy of vernier caliper is limited, and when reading the following reading of millimeter the suitable experience of needs, therefore, measuring accuracy is limited.In addition, adopt external diameter and the internal diameter of measuring respectively pipe to calculate again the wall thickness mode, because being calculates the accumulation brought measuring error after repeatedly measuring again, measuring accuracy is impacted, have again, when needing at a distance wall thickness of measuring distance mouth of pipe end face, claw can't reach the measuring point, and then can't measure.Obviously, prior art adopt the vernier caliper measurement pipe thickness exist measuring accuracy limited, may cause error accumulation and the problem such as can't measure apart from mouth of pipe end face wall thickness at a distance.
Summary of the invention
For solve the measuring accuracy that prior art adopts the vernier caliper measurement pipe thickness to exist limited, may cause error accumulation and the problem such as can't measure apart from mouth of pipe end face wall thickness at a distance, the utility model proposes a kind of band table pipe thickness survey instrument.The utility model band table pipe thickness survey instrument comprises base, sounding rod, dial framework and clock gauge, laterally is fixed with sounding rod at the middle part of base, is fixed with the measurement ball in the termination of sounding rod; Position on the upper side, middle part at base is fixed with dial framework, and the length of dial framework is identical with sounding rod, is provided with fixedly through hole and the bolt of clock gauge in the termination of dial framework, and clock gauge is fixed on the termination of dial framework and measuring head and to measure ball coaxial.
Further, the top of the utility model band table pipe thickness survey instrument dial framework is provided with gusseted.
The useful technique effect of the utility model band table pipe thickness survey instrument is that precision is high, accuracy of reading, and the mouth of pipe end face pipe thickness at a distance of can adjusting the distance is measured.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model band table pipe thickness survey instrument.
Below in conjunction with the drawings and specific embodiments, the utility model band table pipe thickness survey instrument is further described.
Embodiment
Accompanying drawing 1 is the structural representation of the utility model band table pipe thickness survey instrument, in figure, and the 1st, base, the 2nd, sounding rod, the 3rd, dial framework, the 4th, clock gauge, A are measured pipes.As seen from the figure, the utility model band table pipe thickness survey instrument comprises base 1, sounding rod 2, dial framework 3 and clock gauge 4, laterally is fixed with sounding rod 2 at the middle part of base 1, is fixed with the measurement ball in the termination of sounding rod 2; Position on the upper side, middle part at base 1 is fixed with dial framework 3, and the length of dial framework 3 is identical with sounding rod 2, is provided with fixedly through hole and the bolt of clock gauge 4 in the termination of dial framework 3, and clock gauge 4 is fixed on the termination of dial framework 3 and measuring head and to measure ball coaxial.When measuring, first clock gauge is fixedly mounted in the through hole of dial framework termination, and uses bolted.The clock gauge measuring head is contacted with measuring ball, adjust the clock gauge dish and make the position of clock gauge pointer be " 0 ".Be sleeved on measured pipe on sounding rod and keep horizontal level (as shown in A in accompanying drawing 1), the reading that reads clock gauge is the pipe thickness of tested pipe.Than the high order of magnitude of vernier caliper, and be pointer-type during reading numerical values due to the measuring accuracy of clock gauge, therefore, no matter be measuring accuracy, still read precision and all be largely increased.In addition, the length of sounding rod and dial framework all can arbitrarily design as required, therefore, adopts the utility model band table pipe thickness survey instrument mouth of pipe end face pipe thickness at a distance of can adjusting the distance to measure.For guaranteeing intensity and the rigidity of dial framework, the utility model band table pipe thickness survey instrument is provided with gusseted above dial framework, further improved the utility model band table pipe thickness survey instrument reliability and stability.
Obviously, the useful technique effect of the utility model band table pipe thickness survey instrument is that precision is high, accuracy of reading, and the mouth of pipe end face pipe thickness at a distance of can adjusting the distance is measured.
