Abstract
The utility model provides a roundness measurement instrument of steel pipe, which comprises a bracket, a working platform, a sensor with a rotary table and a grating scale displacement display; the sensor with the rotary table is electrically connected with the grating scale displacement display; and the grating scale displacement display is sleeved to the bracket and is slidingly connected with the bracket. When the roundness of the steel pipe is measured, theoretical circumference of the steel pipe is defined in the grating scale displacement display in advance, the steel pipe is placed on the working platform, the roundness measurement instrument of the steel pipe is started and the sensor starts to rotate for a circle around the steel pipe at an angle of 360 degrees; and when the steel pipe does not comply with the requirements, the grating scale displacement display automatically turns on a red alarm lamp, and when the steel pipe complies with the requirements, the display turns on a green lamp. The utility model has the advantages of higher accuracy in roundness measurement of steel pipe, more convenient measurement, simple structure, convenient repair, low processing cost, high production efficiency, high automation level and so on.
Description
Technical field
The utility model belongs to the steel pipe roundness field of measurement, especially relates to a kind of steel pipe roundness measuring instrument.
Background technology
The a collection of steel pipe of in existing technology, having produced will carry out roundness measurement before warehouse-in, in measurement, typically use large-scale thousand fens bars; On the inside and outside footpath of measured object, select some test points; Measure diameter value, find out the poor of maximal value and minimum value, be the deviation from circular from of this pipe.Exist this method efficiency of measurement low, simultaneously it is to be interrupted discontinuously with measurement, is difficult to find accurately the maximal value and the minimum value of caliber, needs manual work to go measurement simultaneously, causes technical matterss such as efficiency of measurement is low, low precision.
Summary of the invention
The problem that the utility model will solve provides a kind of steel pipe roundness measuring instrument, measures automatically when especially being fit to measure steel pipe roundness.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: the steel pipe roundness measuring instrument comprises support, worktable, has sensor, the grating chi displacement display of turntable; The sensor that has turntable is electrically connected with grating chi displacement display, and grating chi displacement display is socketed on the support, is set to be slidingly connected; When measuring steel pipe roundness; In grating chi displacement display, set in advance the theoretical girth of steel pipe, steel pipe is placed on the worktable, start the steel pipe roundness measuring instrument; Sensor promptly begins to rotate a circle for 360 ° around steel pipe; When steel pipe is undesirable, the automatic red warning of grating chi displacement display this moment, the qualified green light that then shows.
Advantage and the good effect that the utlity model has are: owing to adopt technique scheme, it is higher to measure the steel pipe roundness precision, reduces workman's work; Have simple in structurely, easy to maintenance, processing cost is low, production efficiency is high, the automaticity advantages of higher.
Description of drawings
Fig. 1 is the structural representation of the utility model
Among the figure:
1, support 2, worktable 3, have the sensing of turntable
Device
4, grating chi displacement display 5, tested steel pipe
Embodiment
As shown in Figure 1; The utility model steel pipe roundness measuring instrument; Comprise support 1, worktable 2, have sensor 3, the grating chi displacement display 4 of turntable; The sensor 3 that has turntable is connected with grating chi displacement display 4, and grating chi displacement display 4 is socketed on the support 1, can be arranged to slidably connect.
The course of work of this instance: when measuring steel pipe roundness, in grating chi displacement display, set the theoretical girth of steel pipe in advance, steel pipe is placed on the worktable 2; Start the steel pipe roundness measuring instrument, the sensor 3 that has turntable promptly begins to rotate a circle for 360 ° around steel pipe, when steel pipe is undesirable; The 4 automatic red warnings of grating chi displacement this moment display, qualified green light, the full automation of then showing; Reduce workman's work; Increase work efficiency, and with grating chi displacement display, precision is higher.
More than the embodiment of the utility model is specified, but said content is merely the preferred embodiment of the utility model, can not be considered to be used to limit the practical range of the utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the utility model.
