Embodiment
Below, with reference to accompanying drawing specific embodiment of the utility model is described.For the ease of diagram, the size of each parts is extended in the accompanying drawing describes or dwindles description, and content of the present invention is not to be defined in part dimension shown in the accompanying drawing and quantity.
Fig. 1 is the structural representation of the measurer for thickness of sheet metal of the present utility model.Measurer for thickness 1 of the present utility model has the mounting table 10 that is used to place as the sheet metal 2 of measuring object thing, make mounting table 10 travel mechanism that planar move, that comprise length direction travel mechanism 21 and Width travel mechanism 22 (seeing Fig. 2 A), be used to measure the thickness measure mechanism 30 of the thickness of sheet metal 2.
As shown in Figure 1, sheet metal 2 to be measured is lain on the mounting table 10.Thickness measure mechanism 30 is arranged on the top of mounting table 10, can switch between fixed mode and staggered relatively Move Mode that moves up and down.Thickness measure mechanism 30 has a plurality of measurement section 31 in the present embodiment.Example as measurement section can exemplify height-gauge.As the measuring basis face, the height of the face of the measuring basis face opposition side by measuring sheet metal 2 is calculated the thickness of sheet metal 2 with the face that is placed with sheet metal 2 of mounting table 10.
Certainly, the number of measurement section 31 not necessarily must be a plurality of, also can only be provided with one.
Utilize the length direction travel mechanism 21 shown in Fig. 1 that mounting table 10 is moved along the length direction L of sheet metal 2.Utilize the Width travel mechanism 22 shown in the accompanying drawing 2A, mounting table 10 is moved along the Width W of sheet metal 2.Specifically, be provided with the posting 23 of rectangle at the upper surface of mounting table 10, this posting 23 has certain height, forms the groove 25 that can embed sheet metal 2 with the upper surface at mounting table 10.Two ends, the left and right sides at posting 23 are provided with location division 24.As an example, this location division 24 forms a plurality of peristomes of arranging along the Width of sheet metal 2.By selecting different peristomes to aim at, change the position of posting on sheet metal 2 Widths, thereby sheet metal 2 is moved on Width with the location division that is formed on mounting table 10 upper surfaces.
Shown in Fig. 2 A, Fig. 2 B, the upper surface of mounting table 10 of the present utility model is formed with a plurality of attractions hole 11, and, attract 11 corresponding positions, hole to be formed with a plurality of connectors 12 in the side of mounting table 10 and each.These attract holes 11 to communicate with each other the formation internal air passageways in the inside of mounting table 2 with corresponding connector 12.On connector 12, can connect vacuum suction device 40,, thus, attract 11 places, hole to produce negative pressure so that internal air passageways forms vacuum state as negative pressure shape apparatus for converting one example.This vacuum suction device 40 can use known device, is connected with each connector 12 with gas outlet 42 by jointing 41.
Certainly, not necessarily must become vacuum state in the internal air passageways, so long as that the negative pressure that is produced can make sheet metal not fit tightly on reference field with having warpage is just passable.
In addition, attract the set-up mode in hole 11 to be not limited to the situation shown in Fig. 2 A, Fig. 2 B, can be provided with as required crypto set or sparse more.And, attract hole 11 to be set under posting 23 and sheet metal 2 are placed on state on the mounting table 10, can attract hole 11 to cover fully.When posting 23 drives sheet metal 22 change positions, still can attract hole 11 to cover fully.Thus, can be in the attractive force of each position assurance to sheet metal 2.
The formation position of connector 12 is not limited to the side of mounting table, also can be formed on the bottom surface of mounting table.
When using existing measurement mechanism to measure the thickness of sheet metal 2, as shown in Figure 3A, because self there is warpage in sheet metal 2, can not fit tightly with upper surface as the mounting table of measuring basis face, at measurement point A, B, E place, between the upper surface of sheet metal 2 and mounting table 10, there is the gap, causes to measure exactly the thickness of sheet metal 2.
Under the situation of using measurer for thickness 1 of the present utility model to measure, shown in Fig. 3 B, sheet metal 2 fits tightly the upper surface at mounting table 10 under the effect of the negative pressure that attracts 11 places, hole to produce, sheet metal 2 becomes smooth state fully, and the warpage of himself is eliminated fully.Utilize such measurement mechanism to measure, can eliminate the influence that the sheet metal warpage is caused, significantly improve measurement accuracy.
More particularly, as shown in Figure 4, measurement section 31 is moved down into the upper surface position contacting with sheet metal 2, measures the height h of sheet metal upper surface.The height of the upper surface of mounting table 10 is determined in advance as reference value h0.Poor according between measuring height h and the reference value h0 can be calculated the thickness of sheet metal 2.Utilize a plurality of measuring heads 31, can measure a plurality of points of sheet metal 2, and calculate mean value.
These a plurality of measuring heads 31 can be measured each point on the sheet metal 2 one by one, from improving the angle of efficiency of measurement, preferably simultaneously a plurality of measurement points on the sheet metal 2 are measured.
And, because sheet metal 2 can planar move under the effect of travel mechanism, therefore, can measure each point on the sheet metal 2 easily, easily realize measuring comprehensively.
As measurement section, enumerated the height-gauge of the height of sheet metal being measured with the way of contact 31, but also can use the height sensor of measuring with non-contacting mode, for example photovoltaic.
More than embodiment of the present utility model is illustrated, still, obviously, this embodiment also can carry out various changes.Such change should not thought and broken away from protection domain of the present utility model, is that tangible change all is included in the scope of the present utility model for the person of ordinary skill of the art.
