Abstract
The invention relates to the technical field of inside and outside diameter measuring instruments, and in particular relates to an inside and outside diameter measuring instrument for a stainless steel pipe. The instrument comprises two supporting seats which are symmetrically arranged at the left side and the right side of the stainless steel pipe; a reflecting measuring body for measuring the distance to the adjacent outer sidewall of the stainless steel pipe is arranged at the inner side of the upper surface of each supporting seat; an ultrasonic measuring body for measuring the distance to the adjacent inner sidewall of the stainless steel pipe is arranged at the outer side of the upper surface of each supporting seat; the space between the two reflecting measuring bodies is l, and the space between the two ultrasonic measuring bodies is L. The inside and outside diameter measuring instrument for the stainless steel pipe is simple in structure, fast to measure, and high in accuracy.
Description
Technical field
The present invention relates to the technical field of internal-and external diameter measuring instrument, especially a kind of weldless steel tube internal-and external diameter measuring instrument.
Background technology
Weldless steel tube has hollow section, and a large amount of pipeline being used as conveying fluid, as transfer oil, rock gas, coal gas, water and some solid material etc.Weldless steel tube compared with the solid steel such as round steel, under identical bending resistance twisting strength, the lighter in weight of weldless steel tube; Meanwhile, weldless steel tube is also widely used in manufacturing structure part and mechanical component, and as the steel framing scaffold etc. in oil drill rocker, truck drive shaft, bicycle rack and building operation, stock utilization is high, and manufacturing process is simple and easy, and machining period reduces.
Just because of the singularity of weldless steel tube purposes, therefore, needing to measure the indices of weldless steel tube in production run, is exactly wherein an important step to the measurement of its internal-and external diameter.But the existing measuring instrument complex structural designs for measuring internal-and external diameter, measure operation very loaded down with trivial details, the degree of accuracy measured is also poor simultaneously.
Summary of the invention
The technical problem to be solved in the present invention is: in order to solve the prior art Problems existing in above-mentioned background technology, provides a kind of weldless steel tube internal-and external diameter measuring instrument, and structure is simple, and measure fast, accuracy is high.
The technical solution adopted for the present invention to solve the technical problems is: a kind of weldless steel tube internal-and external diameter measuring instrument, there is the supporting seat that two are symmetricly set in the weldless steel tube left and right sides, the inner side of described each supporting seat upper surface is provided with and can be used for measuring the reflective measurement body that it arrives the spacing of weldless steel tube adjacent outer wall, the outside of each supporting seat upper surface is provided with and can be used for measuring the ultrasonic measurement body that it arrives the spacing of weldless steel tube adjacent inside side wall, distance between described two reflective measurement bodies is l, distance between two described ultrasonic measurement bodies is L.
Further specifically, the described reflective measurement bulk measurement in left side its be l1 to the distance between weldless steel tube adjacent outer wall, the described reflective measurement bulk measurement on right side its be l2 to the distance between weldless steel tube adjacent outer wall.
Further specifically, the described ultrasonic measurement bulk measurement in left side its be L1 to the distance between weldless steel tube adjacent inside side wall, the described ultrasonic measurement bulk measurement on right side its be L2 to the distance between weldless steel tube adjacent inside side wall.
For the ease of measuring the inside/outside diameter size at weldless steel tube diverse location place, therefore described internal-and external diameter measuring instrument also has the driving mechanism moved forward and backward for controlling weldless steel tube.
The invention has the beneficial effects as follows: weldless steel tube internal-and external diameter measuring instrument of the present invention, structural design is simple, and amount of parts is few, easy to maintenance, Automatic survey degree is high, and reflective measurement body and ultrasonic measurement body can measure related data automatically, measuring speed is fast, and accuracy is high; Meanwhile, the measurement of internal-and external diameter can also be carried out to weldless steel tube diverse location place.
