Abstract
The utility model relates to an adjustable steel tube circular degree and outer diameter snap gauge, which is provided with an inverse V-shaped main body. Measure mouths are arranged at the inner sides of the two hypotenuses of the inverse V-shaped main body, a fixing sleeve is fixed at the top end of the inverse V-shaped main body through a fastening nut at the lower end and a nut at the upper end, an dial indicator is clipped at the hollow upper part of the fixing sleeve, a core rod is arranged at the hollow lower part of the fixing sleeve, and the top part of the core rod is contacted with the measuring head of the dial indicator. A handle is arranged at the side upper side of the V-shaped main body. The utility model has the advantages that the adjustable steel tube circular degree and outer diameter snap gauge can be used on spot during the production process of the steel tube, especially under the condition of high temperature, the measurement is rapid, accurate, convenient and safe when the circular degree and the outer diameter of the steel tube are measured.
Description
Technical field
The invention belongs to measurer, particularly a kind of Variable Type Circular Degree of Steel Tube and Exterior Diameter Snap Gauge
Background technology
At present,, measure steel pipe roundness and external diameter and generally use common calliper in the production scene of steel pipe, or long pawl vernier caliper.Especially in the situation of high temperature, make troubles to operating personnel, also dangerous, inaccurate again.
Summary of the invention
Technical matters to be solved by this invention is: a kind of Variable Type Circular Degree of Steel Tube and Exterior Diameter Snap Gauge is provided, reaches the production scene at steel pipe, especially when the situation of high temperature, it is accurate to measure steel pipe roundness and external diameter, convenient rapidly, safety.
Technical scheme of the present invention is:
A kind of Variable Type Circular Degree of Steel Tube and Exterior Diameter Snap Gauge, it is characterized in that: the body that an inverted v-shaped is arranged, the inboard of two hypotenuses of the body of inverted v-shaped is to measure mouth, the top of the body of inverted v-shaped is installed with the fixed cover of the logical heart, fixed cover is fixed on the top of the body of inverted v-shaped by the nut of the set nut of lower end and upper end, the top card of the logical heart of fixed cover has dial gauge, and core bar is arranged at the bottom of the logical heart of fixed cover, and the top of core bar contacts with the measuring head of dial gauge.
The top of the logical heart of fixed cover is stuck in dial gauge by jump ring the top of the logical heart of fixed cover.There is handle the side top of the body of inverted v-shaped.
Effect of the present invention is:
This Variable Type Circular Degree of Steel Tube and Exterior Diameter Snap Gauge uses in the production scene of steel pipe, especially when the situation of high temperature, when measuring steel pipe roundness and external diameter, measures rapidly, and is accurately convenient, safety.
Description of drawings
Fig. 1 is the structural representation of Variable Type Circular Degree of Steel Tube and Exterior Diameter Snap Gauge
Fig. 2 is the structural drawing of Variable Type Circular Degree of Steel Tube and Exterior Diameter Snap Gauge
Embodiment
Fig. 1, a kind of Variable Type Circular Degree of Steel Tube and Exterior Diameter Snap Gauge shown in 2, the body 1 that an inverted v-shaped is arranged, the inboard of two hypotenuses of the body of its inverted v-shaped is to measure mouth, the top of the body of inverted v-shaped is installed with the fixed cover 2 of the logical heart, fixed cover is by the set nut 3 of lower end and the nut 4 of upper end, packing ring 5 is fixed on the top of the body of inverted v-shaped, the top of the logical heart of fixed cover is blocked dial gauge by the jackscrew on jump ring 6 and the fixed cover 7, the installation site of dial gauge can up-down adjustment, seam is arranged at the bottom of the logical heart of fixed cover, stop portion is installed core bar 8, and the top of core bar contacts with the measuring head of dial gauge.The side top of the body of inverted v-shaped is equipped with handle 9.Be convenient to manipulate.Because the installation site of dial gauge can up-down adjustment, can realize that therefore a kind of calliper of specification can be realized measuring to the approaching steel pipe of several external diameters.
During measurement, grasp handle, the measurement mouth of the body two hypotenuse inboards of inverted v-shaped is stuck on the steel pipe, measure numerical value, can draw diameter of steel tube through the table of comparisons by dial gauge.When steel pipe rotates, can obtain circularities from the swing of dial gauge indicator.
