The content of the invention
The purpose of this utility model is to provide a kind of whole machine low cost, measure convenient and swift accurate flatness detection Machine.
To reach object above, this utility model is adopted the following technical scheme that.
A kind of contact Pneumatic plane degree testing machine, including:Base plate, is used for placing the benchmark of measured piece on base plate Flat board, the electronic ruler being vacantly arranged on above benchmark flat board, and drive the vertical cylinder of electronic ruler up and down motion;Its feature exists In the quantity of, the electronic ruler be nine, nine electronic rulers by 3 × 3 array arrangements in an electronic ruler fixed plate, the electronics Chi fixed plate is fixed with the cylinder rod of vertical cylinder, and the vertical cylinder is connected with a PLC, and the signal provided according to PLC drives Dynamic electronic ruler fixed plate moves up and down.
Used as with improvement, the benchmark flat plate bottom is provided with the adjusting means for adjusting benchmark flatbed horizontal degree.
As with improvement, between the electronic ruler fixed plate and cylinder rod fixation is threaded connection.
As with improvement, pillar panel is provided with base plate, is fixed with the side of pillar panel and crosses out top board, it is described Vertical cylinder is arranged on top board.
As with improvement, guide pillar, the guide pin bushing for cooperating, the guide pillar are respectively equipped with top board and electronic ruler fixed plate It is slidably mounted in guide pin bushing.
As with improvement, being connected with air-operated solenoid valve and air filter on vertical cylinder, the air-operated solenoid valve and Air filter is arranged on the opposite side of pillar panel.
Used as with improvement, the electronic ruler is connected with PLC signals.
The beneficial effects of the utility model are:
When actually detected, by benchmark flat board level-off, vertical cylinder action is controlled by PLC, make the measurement head of electronic ruler Contact with benchmark flat board, the mechanical displacement that at this moment electronic ruler is measured should be 0.After benchmark flat board level-off, by tested flat board Display screen is positioned on benchmark flat board, and by PLC vertical cylinder action is controlled, and makes the measurement head and panel display screen table of electronic ruler The vertical simultaneously effective contact in face, you can while the mechanical displacement between nine points of flat pannel display screen surfaces and benchmark flat board is changed Export into the curtage linear with displacement, Jing data processings obtain flatness error value, realize panel display screen The quick measurement of surface planarity.

Specific embodiment
Essence of the present utility model is more fully understood for convenience of those skilled in the art, it is new to this practicality below in conjunction with the accompanying drawings The specific embodiment of type is described in detail.
As shown in Figure 1-Figure 3, a kind of contact Pneumatic plane degree testing machine, including:Base plate 1, is used on base plate 1 The benchmark flat board 2 of measured piece is placed, the electronic ruler 3 of the top of benchmark flat board 2 is vacantly arranged on, and drives electronic ruler to transport about 3 Dynamic vertical cylinder 4;Characterized in that, the quantity of the electronic ruler 3 is nine, nine electronic rulers are by 3 × 3 array arrangements one In electronic ruler fixed plate 5, the electronic ruler fixed plate 5 is fixed with the cylinder rod of vertical cylinder 4, the PLC of the vertical cylinder 4 and Connection, and the signal provided according to PLC drives electronic ruler fixed plate 5 to move up and down.
Wherein, the loading end that the benchmark flat board 2 is used for ensureing measured piece is horizontal plane, thus, at the bottom of benchmark flat board 2 Portion is provided with the adjusting means for adjusting benchmark flatbed horizontal degree.For the convenience of installing/dismounting, the electronic ruler fixed plate 5 and gas Fixation is threaded connection between cylinder rod.
Vertical cylinder 4, the package assembly of electronic ruler fixed plate 5 are in the present embodiment:Pillar panel 6 is provided with base plate 1, It is fixed with the side of pillar panel 6 and crosses out top board 7, the vertical cylinder 4 is arranged on top board 7.In top board 7 and electronic ruler Guide pillar, the guide pin bushing 8 for cooperating is respectively equipped with fixed plate 5, the guide pillar is slidably mounted in guide pin bushing.By guide pillar, guide pin bushing Design, it is ensured that vertical cylinder motion precision, improve motion stability.
Air-operated solenoid valve 9 and air filter 10, the air-operated solenoid valve 9 and air are also associated with vertical cylinder 4 Filter 10 is arranged on the opposite side of pillar panel 6, i.e. be arranged in the rear of vertical cylinder.
