Abstract

PURPOSE:To measure the accuracy of a plane simply, by fixing mutually insulated conductors to a plate body so that specified flatness is kept, and lighting only the contact part of the conductor when said device is mounted on a material to be measured. CONSTITUTION:Many round rods 4 are fixed to a measuring part, on which a material to be measured 6 that forms a measuring surface is mounted. The round rods 4 are insulated one another. The rods are polished so that necessary flatness is obtained and form measuring points. Display lamps 5, 7 and the like are arranged on a flat part in correspondence with the measuring points of the round rods 4. The flat part is provided on a judging and display part 2. The round rods 4 in the measuring part 1 and the lamps 5, 7 and the like on the display part 2 are electrically wired in a corresponding mode. In this constitution, when the measuring surface of the material to be measured 6 is mounted on the measuring part 1 and set, the display lamp 5 of the judging part 2 corresponding to the position, which is contacted with the metal rod 4, is lighted and displayed. The position of the lamp 7, which is not lighted, indicates the concave surface. The material to be measured 6 is being machined until all the lamps are lighted, and the measurement can be simply repeated.

Description

DETAILED DESCRIPTION OF THE INVENTION [Prior Art] The present invention relates to a simple flatness measuring device that easily measures the flatness of a conductive plate.

[Prior art]

BACKGROUND ART Conventionally, there have been expensive measuring instruments adapted to measure the flatness of components (conductor plates) that require high precision. on the other hand,
Although it cannot be determined visually, there has been no simple method for measuring the axiality of parts that does not require the precision of using a high-precision flatness range finder.

[Purpose of the invention]

An object of the present invention is to provide a simple flatness measuring device that satisfies such requirements and allows easy inspection of flatness accuracy.

[Structure of the invention]

The simple flatness measuring device of the present invention consists of a plate body on which a plurality of conductor bars on which objects to be measured are placed are fixed and insulated from each other, and the ends of these conductor rods in contact with the object to be measured are A measuring section maintained at a predetermined flatness; a display section having a plurality of indicator lights arranged on a flat plate corresponding to the arrangement of the conductor bars; and one end of each of the indicator lights are connected so that they correspond to each other, and a power supply connection part that supplies power for the indicator light between the other end of the indicator light and the object to be measured, which are commonly connected. Contains and consists of.

〔Example〕

Next, the present invention will be explained in detail with reference to the drawings.

FIG. 1 is a perspective view showing the configuration of an embodiment of the present invention. In this embodiment, the part on which the object to be measured 6 serving as the measurement surface is placed is a flat plate body in which a large number (eight) of metal round bars 4 are fixed and electrically insulated from each other. a measuring part 1 whose end part 4 has been given a smooth flatness by polishing or the like;
Display lamps (5
, 7), and cables 8 and 1 connected between the measurement section 1 and the judgment display section 2 so that each metal round bar 4 and each display lamp correspond to each other. It is comprised of a power supply section 3 connected to connection wirings 9 and 10 between the display lamp and the object to be measured 6.

When the measuring part of the object to be measured 6 is placed and set on the measuring part 1 of this device, the indicator lamp 5 of the judgment display part 2 corresponding to the position in contact with the metal round bar 4 lights up and is displayed. Ru.

Further, the position of the indicator lamp 7 that is not lit indicates that it is a concave surface.

Therefore, in order to obtain a predetermined flatness, distance measurement can be easily repeated without processing the object until all the lamps (measuring section #) are lit.
