Abstract
The utility model discloses a portable test pen for detecting the flatness, which comprises a hollow cylinder with a gap in the horizontal bottom part, a capacitor, a metal ball and a capacitor detector, wherein the capacitor is arranged at the gap inside the cylinder, the metal ball is arranged between polar plates of the capacitor, a part of the metal ball is exposed out of the cylinder through the gap, and the capacitor detector is connected with the capacitor. The portable test pen disclosed by the utility model solves a technical problem of measuring the concave-convex degree of a plate in a small local range.
Description
Technical field
The utility model relates to field tests, particularly a kind of portable test pen for detection of 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:
Existing smooth tester volume is very much not easy to carry, and can not test at some less subranges, more can not quantize the concavo-convex degree of some points, is unfavorable for the production of industrialization precision.
Utility model content
The purpose of this utility model is to provide a kind of portable test pen for detection of flatness, solving existing smooth tester volume is very much not easy to carry, and can not test at some less subranges, more can not quantize the concavo-convex degree of some points, be unfavorable for the technical matters that industrialization precision is produced.
The technical solution adopted in the utility model is: a kind of portable test pen for detection of flatness, comprising: the cylinder with hollow jaggy in horizontal bottom; The electric capacity arranging in the indentation, there of column body, the distance between two pole plates of electric capacity is greater than the diameter of breach; Be arranged at the Metal Ball between capacitor plate, the diameter of Metal Ball is greater than breach, and a part for Metal Ball is exposed to the outside of cylinder by breach; The capacitance detector being connected with electric capacity.
Further, depart from the frame that stops between capacitor plate at the outer setting barrier metal ball of electric capacity.
Further, breach is circular.
Further, at cylinder outer setting rubber sleeve.
Further, in capacitance detector, be provided with the display being connected with capacitance detector.
By such scheme, smooth tester is convenient for carrying, can in a less subrange, test, can also quantize the concavo-convex degree of some points, promote industrialization precision to produce.
Accompanying drawing explanation
Fig. 1 is a kind of portable test pen for detection of flatness in embodiment.
Embodiment
As shown in Figure 1, a kind of portable test pen for detection of flatness, comprising: the cylinder 2 with jagged 8 hollow in horizontal bottom; The electric capacity 6 arranging at breach 8 places of cylinder 2 inside, the distance between 6 two pole plates of electric capacity is greater than the diameter of breach 8; Be arranged at the Metal Ball 5 between electric capacity 6 pole plates, the diameter of Metal Ball 5 is greater than breach 8, and a part for Metal Ball is exposed to the outside of cylinder 2 by breach 8; The capacitance detector 1 being connected with electric capacity 6.
Depart from and stop frame 4 between electric capacity 6 pole plates at the outer setting barrier metal ball 5 of electric capacity 6.Breach 8 is circular.At cylinder 2 outer setting rubber sleeves 3.In capacitance detector 1, be provided with the display 7 being connected with capacitance detector 1.
When use, test pen is placed on the sheet material that needs test, by the bottom of test pen and sheet material laminating, then move horizontally test pen, Metal Ball 5 touches after sheet material, move straight up, read registration by display 7 or capacitance detector 1, in the time moving to sheet material depression or protrusion place, the Metal Ball 5 of test pen relies on gravity downwards or because the reacting force of sheet material moves up, change capacitance, thereby obtain the flatness of sheet material.
The utility model moves up and down by Metal Ball, change the medium between capacitor plate, thereby the capacitance that impact detects, adopt the test pen of this scheme, not only be convenient for carrying, can in a less subrange, test, can also quantize the concavo-convex degree of some points, promote industrialization precision to produce.
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.
