CN104006769A - Jig used for detecting planarity of fin tube - Google Patents

Abstract

The invention provides a jig used for detecting the planarity of a fin tube. The jig comprises a detecting platform, a height rod perpendicular to the detecting platform, and an induction cover capable of sliding on the height rod vertically. The detecting platform comprises at least two standard components. The standard components protrude out of the table board of the detecting platform. The interval range between the standard components and the induction cover is from 0.05mm to 0.8 mm. The jig used for detecting the planarity of the fin tube is simple and reasonable in structure, and can meet the requirement for detecting a plurality of detection points of the planarity of the fin tube and improve the detection efficiency; moreover, the jig and a planarity detector are used together, if a work-piece exceeding the planarity range is detected, data can be automatically displayed, a user does not need to see a screen of the planarity detector, and therefore the detection efficiency and the detection precision can be improved.

Brief description of the drawings

Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.

Fig. 1 is structural representation of the present invention.

Wherein, 1-detection platform, 11-standard component, 12-groove, 2-fin pipe, 3-responds to cover, 4-box, 41-display screen, 5-height bar.

Embodiment

In order to make those skilled in the art person understand better the present invention program, and above-mentioned purpose of the present invention, feature and advantage can be become apparent more, below in conjunction with embodiment and embodiment accompanying drawing, the present invention is further detailed explanation.

As shown in Figure 1, a kind of tool for detection of fin flatness provided by the invention, it mainly comprises detection platform 1 in horizontal direction, perpendicular to the height bar 5 of above-mentioned detection platform 1 and the induction cover 3 that can slide up and down on described height bar 5.

Concrete, in the present embodiment, have groove 12 in the inside of detection platform 1, in groove 12, place standard component 11, in the present embodiment, the number of standard component 11 has two at least, one end of induction cover 3 is corresponding with above-mentioned one of them standard component 11, induction cover 3 has certain spacing to 11, standard component, and spacing range of the present invention is 0.05～0.8mm, i.e. the fin plumber part between 0.05～0.8mm mainly for detection of flatness scope.

In other embodiments, can also respond to cover 3 at the height of establishing on graduated height bar 5 by adjusting, change the distance between induction cover 3 and standard component 11; Can also in groove 12, protrude by adjustment criteria part 11 and the height of detection plane 1 carrys out the distance between adjustment criteria part 11 and induction cover 3.In the present invention, be achieved in that first, the outer dia of standard component 11 matches with the internal diameter of groove 12, and standard component 11 is to adopt the material with caoutchouc elasticity to make, can up-down adjustment by outer inner effect in groove 12, in the time there is no external force, standard component 11 also can not slide up and down in groove 12.

In use, fin pipe 2 to be detected is placed on above the detection platform 1 of level, regulate the scope of the flatness detecting instrument flatness linking together with this tool according to product requirement, the distance that this tool is responded between cover 3 and standard component 11 accordingly also can regulate, can automatically regulate herein, also can manual adjustments, then the detection laser line of detector can, through standard component 11 and induction cover 3, if the laser rays line between two standard components 11 there will be bending, illustrate that fin pipe outside has projection.Whether on detector, can show related data, see and go beyond the scope, if gone beyond the scope, detector also can automatic alarm, has improved like this detection precision.

And, in most preferred embodiment of the present invention, induction cover 3 is to be realized and on height bar 5, regulated height by a box 4 being set on height bar 5, the inside of box 4 has fixing induction to cover on the fastener on height bar 5, can after adjustment height, ensure that by this fastener induction cover 3 no longer moves up and down, and the outside of box 4 is also provided with display screen 41, because box directly links together with detector, the detection data of detector can show by display screen 41, do not need like this testing staff to see the screen of detector, time saving and energy saving.

Tool for detection of fin flatness of the present invention, it is simple and reasonable, can meet the demand that fin pipe flatness needs detect multiple check points, improve detection efficiency, and this tool is that combination planar degree detector uses together, if detect the workpiece that exceeds flatness scope, can automatically show data, need not be without the screen of seeing flatness detecting instrument, improve detection efficiency and detected precision.Can be for the flatness of batch detection fin pipe.

Above-mentioned above; be only the specific embodiment of the present invention, protection scope of the present invention is not limited to this, any be familiar with those skilled in the art the present invention disclose technical scope in; the variation that can expect easily or replacement, within all should being encompassed in protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claim was defined.
