Abstract
The utility model discloses a tester for measuring the flatness of a plate. The tester comprises a shell, a hollow column, a pressure sensor, liquid, a voltage meter and a power supply, wherein the bottom part of the shell is set to be horizontal; the hollow column is attached to the bottom part of the shell, and the bottom part of the hollow column is parallel to the bottom part of the shell; the pressure sensor is arranged at the left end of the hollow column, and the right side of the hollow column is provided with the liquid which can not completely fill the hollow column; the voltage meter is connected with the pressure sensor through a wire; the power supply is connected with the pressure sensor and the voltage meter, and the power supply, the pressure sensor and the voltage sensor form a circuit. The tester for measuring the flatness of the plate solves the technical problem that big errors in the processing and production process are not conducive to automatic production.
Description
Technical field
The utility model relates to field tests, particularly a kind of tester of sheet material measurement 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 sheet material measurement 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 sheet material measurement flatness, comprising: bottom is set to the shell of level; Fit in the open column of outer casing bottom, the bottom of open column is parallel with the bottom of shell; Be arranged on the pressure transducer of open column left end, the liquid that can not fill open column is completely equipped with on the right side of open column; The voltage table being connected with pressure transducer by electric wire; With the power supply that pressure transducer, voltage table are connected, power supply, pressure transducer, voltage table form a loop.
Further, tester also comprises: the display being connected with voltage table.
Further, 4/5ths of the volume of the volume duty stem of liquid.
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 sheet material measurement flatness in embodiment.
Embodiment
As shown in Figure 1, a kind of tester of sheet material measurement flatness, comprising: bottom is set to the shell 1 of level; The open column 6 that fits in shell 1 bottom, the bottom of open column 6 is parallel with the bottom of shell 1; Be arranged on the pressure transducer 7 of open column 6 left ends, the liquid 5 that can not fill open column 6 is completely equipped with on the right side of open column 6; The voltage table 3 being connected with pressure transducer 7 by electric wire 2; With the power supply that pressure transducer 7, voltage table 3 are connected, power supply, pressure transducer 7, voltage table 3 form a loop.
Further, tester also comprises: the display 4 being connected with voltage table.
Further, 4/5ths of the volume of the volume duty stem 6 of liquid 5.
When use, tester is fitted in to tested sheet material, the liquid 5 in open column 6 can be mobile, and center is offset, and the pressure generation respective change that pressure transducer 7 is subject to causes that the reading of voltage table 3 changes, thereby completes the detection of flatness.
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.
