The tester provided by the utility model solves the technical problems of quite large errors and inconvenient automation production in a production process.
Description
Technical field
The utility model relates to field tests, particularly a kind of tester of instant playback sheet material flatness.
Background technology
In machinery production process, all can measure the flatness of sheet material in a lot of occasions, to guarantee mechanical normal operation, guarantee product quality.Such as sheet material being aligned in smooth process at aligning planisher, the flatness of sheet material is the important measurement index of the quality of product; Utilizing in the process of sheet material processing and manufacturing parts, grasp accurate sheet material flatness and can reduce mismachining tolerance, save processing cost.At present, conventionally adopt the smooth tester of globule formula, rely on operating personnel to read corresponding scale according to the position of the globule, obtain flatness.
State in realization in the process of technical scheme, inventor finds, at least has following technical matters in prior art:
Depend on workman's direct feel by manually obtaining flatness, the flatness that different workmans reads is different, and error is larger, has strengthened the difficulty of following process and suitability for industrialized production, on the other hand, is unfavorable for automated production, has increased the probability going wrong.
Utility model content
The purpose of this utility model is to provide a kind of tester of instant playback sheet material flatness, solve the direct feel that depends on workman in processing process by manually obtaining flatness, the flatness that different workmans reads is different, error is larger, strengthen the difficulty of following process and suitability for industrialized production, on the other hand, be unfavorable for automated production, increased the technical matters of the probability going wrong.
The technical solution adopted in the utility model is: a kind of tester of instant playback sheet material flatness, comprising: have the base of horizontal bottom, the vertical xsect of base is inverted T-shape; The horizontal thin rectangular parallelepiped support being fixedly connected with base top, support is provided with the rectangular body cavity of hollow, on the inboard wall outer surface of rectangular body cavity, is provided with plain conductor; Vertically be arranged at rectangular body cavity inside, and the flat scale that can move freely, on the outside surface of the length direction of scale, be vertically provided with the resistance wire directly contacting with object under test, resistance wire and plain conductor are slidably connected; Be placed in internal stent, the reometer being connected with plain conductor, reometer is also connected with the display that is placed in a top of the trellis; Be placed in the power supply of base inside, one of them electrode of power supply is connected with reometer by wire, another electrode grounding.
Further, the hinged metallic sheave in the bottom of flat scale, resistance wire and pulley are slidably connected.
Further, support is fixedly connected with base by nut.
Further, power supply is dry cell or accumulator.
Pass through such scheme, the irregularity degree of plate is converted into electric signal, increase on the one hand sensitivity, easy to use, simple to operate, read easily, can not affect reading because of different operating personnel's difference, on the other hand, electric signal and other automation equipment can also be communicated, realize automated production.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of a kind of tester of instant playback sheet material flatness in embodiment;
Fig. 2 is the vertical view of a kind of tester of instant playback sheet material flatness in embodiment.
Embodiment
As depicted in figs. 1 and 2, a kind of tester of instant playback sheet material flatness, comprising: have the base 1 of horizontal bottom, the vertical xsect of base 1 is inverted T-shape; The horizontal thin rectangular parallelepiped support 6 being fixedly connected with base 1 top, support 6 is provided with the rectangular body cavity 9 of hollow, is provided with plain conductor 3 on the inboard wall outer surface of rectangular body cavity 9; Vertically be arranged at rectangular body cavity 9 inside, and the flat scale 10 that can move freely, on the outside surface of the length direction of scale 10, be vertically provided with the resistance wire 7 directly contacting with object under test, resistance wire 7 is slidably connected with plain conductor 3; Be placed in support 6 inside, the reometer 5 being connected with plain conductor 11, reometer 5 is also connected with the display 4 that is placed in support 6 tops; Be placed in the power supply 2 of base 1 inside, one of them electrode of power supply 2 is connected with reometer 5 by wire, another electrode grounding.
The hinged metallic sheave 8 in bottom of flat scale 10, resistance wire 7 is slidably connected with pulley 8.Support 6 is fixedly connected with base 1 by nut.Power supply 2 is dry cell or accumulator.10 centimetres of base 1 length, wide 10 centimetres, high 20 centimetres.50 centimetres of support 6 length, wide 10 centimetres, high 10 centimetres.
When use, base 1 is placed on horizontal stand, moves horizontally scale 10, the concavo-convex fluctuating of sheet material causes that scale 10 in the vertical directions move up and down, the resistance that has changed place in circuit, causes curent change, thereby reflects the flatness of sheet material by the current value capturing.
Pass through such scheme, the irregularity degree of plate is converted into electric signal, increase on the one hand sensitivity, easy to use, simple to operate, read easily, can not affect reading because of different operating personnel's difference, on the other hand, electric signal and other automation equipment can also be communicated, realize automated production.
Above; it is only embodiment of the present utility model; but protection domain of the present utility model is not limited to this; any be familiar with those skilled in the art the utility model disclose technical scope in; the variation that can expect easily or replacement, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claim.
