Abstract
The utility model provides a measuring tool for measuring the wall thickness of a pipe, which comprises a vernier caliper and two long measuring rods; the vernier caliper is a digital display vernier caliper, bolt holes are respectively drilled in outer measuring claws of the vernier caliper, and the upper ends of the two long measuring rods are respectively fixed on a fixed claw and a movable claw of the outer measuring claw through bolts penetrating through the bolt holes; the lower ends of the two long measuring rods are provided with measuring heads which are contacted with each other in the horizontal direction. The measuring tool for measuring the wall thickness of the tube can directly read the measured value of the wall thickness of the tube, and is convenient, practical and high in adaptability.
Description
Technical Field
The utility model relates to a measuring tool, concretely relates to survey measuring tool of buret wall thickness.
Technical Field
The steel anchor is an accessory of a strain clamp of an electric power fitting product, the strain clamp is used for connecting a conducting wire, a ground wire and other fittings of an electric power line, and the steel anchor plays an important connecting role. The steel anchor hole of the strain clamp of the steel-cored aluminum strand and the aluminum-clad steel strand is a deep blind hole with large length and diameter, and the concentricity requirement is strict, generally phi 0.2. The difficulty in checking the concentricity of the deep part in the hole is high, and the concentricity is generally calculated by checking the wall thickness. The existing measuring tool for measuring the wall thickness of the pipe has the defects of complex structure, higher price, inconvenience in carrying, low adaptability, incapability of directly obtaining data and the like.
Disclosure of Invention
The utility model provides a can directly read the measuring tool of buret wall thickness measurement numerical value, convenient and practical strong adaptability's survey buret wall thickness.
The measuring tool for measuring the wall thickness of the pipe comprises a vernier caliper and two long measuring rods; the vernier caliper is a digital display vernier caliper, bolt holes are respectively drilled in outer measuring claws of the vernier caliper, and the upper ends of the two long measuring rods are respectively fixed on a fixed claw and a movable claw of the outer measuring claw through bolts penetrating through the bolt holes; the lower ends of the two long measuring rods are provided with measuring heads which are contacted with each other in the horizontal direction.
The measuring head is a natural extension of the material of the measuring long rod.
The measuring long rod and the measuring head are made of 4Cr13 stainless steel.
The end contact surface of the measuring head is a spherical surface.
The main body of the long measuring rod fixed on the fixed jaw of the outer measuring jaw is vertical to the body of the vernier caliper.
The spherical radius of the end part of the measuring head is between 0.5 and 5 millimeters.
When the device is used, firstly, two measuring heads at the lower ends of two long measuring rods are contacted, a zero setting button of the digital display vernier caliper is pressed, then the long measuring rods fixed on the fixed clamping jaws are inserted into a pipe, and then the movable clamping jaws of the vernier are slid to measure the wall thickness of the pipe; the long measuring rods with different lengths can be replaced to adapt to the measurement of the wall thickness of the pipe with different lengths.
A survey measuring tool of buret wall thickness simple structure, can directly read buret wall thickness measurement numerical value, strong adaptability.
