Abstract
The invention discloses a pipe roundness detector which comprises a fixing seat, sliding roller ways, a moving frame, a manual rotating device, a contact-type probe, a digital sensor, a displayer and an alarming device. The sliding roller ways are symmetrically arranged on the left side and the right side of the fixing seat, the moving frame is arranged on the sliding roller ways, the manual rotating device is arranged on the upper portion of the moving frame, and the contact-type probe is sequentially connected with the digital sensor, the displayer and the alarming device. By the above mode, the pipe roundness detector can realize whole-course detection of roundness of pipes along the axial direction, is convenient and simple to operate and high in detection efficiency and can be used for detection having high requirements on outer diameter roundness of the pipes.
Description
Technical field
The present invention relates to detecting instrument, particularly relate to a kind of tubing roundness tester.
Background technology
The application of tubing is comparatively general.By the range of application of pipeline, pipeline has gas pipeline, fluid pipeline, cable pipeline etc.; Divide by the making material of tubing, have the wiping of plastic pipe, stainless steel pipe, glass reinforced plastic pipe, steel pipe etc.No matter be which kind of tubing, its range of application is all more extensive.
In use, very strict to the requirement of its wall thickness and material, especially in same working environment, the wall thickness of same tubing must ensure unanimously, in case tube wall thickness is uneven, easily to rupture at weakness tubing in principle.And tubing is after manufacture is good, how detecting a tubing many places wall thickness, is the main bugbear that tubing detects.
Summary of the invention
The technical matters that the present invention mainly solves is to provide a kind of tubing roundness tester, and can detect the circularity of tubing is in axial direction omnidistance, simply easy to operate, detection efficiency is high, can be used for requiring higher detection to tube outer diameter circularity.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: provide a kind of tubing roundness tester, comprise holder, slip roller-way, movable stand, hand whirligig, contact probe, digital sensor, display and warning device, described sliding rail is symmetricly set on the holder left and right sides, described movable stand is arranged on slip roller-way, described hand whirligig is arranged on movable stand top, and described contact probe is connected successively with digital sensor, display and warning device.
In the present invention's preferred embodiments, described movable stand comprises perpendicular support, shifting roller and toroidal frame, and described shifting roller is arranged on perpendicular support base both sides, and described toroidal frame is fixed on perpendicular support top end.
In the present invention's preferred embodiments, said toroidal frame comprises fixed mount and tressel, and described tressel is fixed on tressel inside by bearing.
In the present invention's preferred embodiments, described hand whirligig comprises rocking arm and connecting rod, and described connecting rod one end is connected with tressel, and one end is connected with rocking arm in addition.
In the present invention's preferred embodiments, described warning device is audible-visual annunciator.
The invention has the beneficial effects as follows: a kind of tubing roundness tester of the present invention, can detect the circularity of tubing is in axial direction omnidistance, simply easy to operate, detection efficiency is high, can be used for requiring higher detection to tube outer diameter circularity.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the embodiment of the present invention, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings, wherein:
Fig. 1 is the structural representation of tubing roundness tester one of the present invention preferred embodiment;
Fig. 2 is the left view of Fig. 1.
Embodiment
Be clearly and completely described to the technical scheme in the embodiment of the present invention below, obviously, described embodiment is only a part of embodiment of the present invention, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making other embodiments all obtained under creative work prerequisite, belong to the scope of protection of the invention.
Refer to Fig. 1 to Fig. 2, the embodiment of the present invention comprises:
A kind of tubing roundness tester, comprise holder 1, slip roller-way 2, movable stand 3, hand whirligig, contact probe 5, digital sensor 6, display 7 and warning device 8, described sliding rail 2 is symmetricly set on holder 1 left and right sides, described movable stand 3 is arranged on slide roller 2 road, described hand whirligig is made up of Rocker arm 5 and connecting rod 4 and is arranged on movable stand 3 top, and described contact probe 5 is connected successively with digital sensor 6, display 7 and warning device 8.
Further, described movable stand comprises perpendicular support 31, shifting roller 32 and toroidal frame, described toroidal frame, be made up of fixed mount 33 and tressel 34, described tressel 34 is connected by bearing 10 with between fixed mount 33, described shifting roller to be fixed on bottom perpendicular support 31 and to be arranged on slip roller-way 2, thus drive movable stand 3 to move left and right on holder 1, connecting rod 4 one end is connected with tressel 34, one end is connected with Rocker arm 5, tressel 34 is driven to rotate by Rocker arm 5, then contact probe 5 carries out 360 ° of rotations along with tressel 34, can detect tubing circularity.
In above-mentioned, when tubing is detected, if circularity does not change, then digital indicator 7, digital sensor 6 and warning device 8 attonity, when circularity changes, contact probe 5 gives digital sensor 6 one signals, variable quantity shows by digital sensor on the display 7, and audible-visual annunciator 8 is reported to the police simultaneously.
The invention has the beneficial effects as follows: a kind of tubing roundness tester of the present invention, can detect the circularity of tubing is in axial direction omnidistance, simply easy to operate, detection efficiency is high, can be used for requiring higher detection to tube outer diameter circularity.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize description of the present invention to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present invention.
