One pedestal offers a window on the table top of pedestal;

One load-bearing glass, it is embedded in the window of above-mentioned table top and does not cover this window fully, and this load-bearing glassy phase is to be slidably structure to window;

One air permeable plate, it is fixedly arranged on load-bearing glass below and blocks this window fully; On this air permeable plate, offer a plurality of bleeder vents;

One snorkel, it is fixedly arranged on the air permeable plate below;

One air compressor, it is communicated with snorkel.

Described snorkel constitutes along the arm of being responsible for a side horizontal expansion and communicate with the person in charge with the person in charge, the complex root of air compressor connection by one, and each arm is arranged in whole air permeable plate below, all offers a plurality of ventholes on each arm.

Described each arm respectively is equipped with solenoid valve near the end of being responsible for, on the madial wall of above-mentioned window, be provided with the air supporting track that is used to inlay load-bearing glass, be provided with the sensing component that is used to control each solenoid valve open and close along this air supporting track, and the end of inlaying of load-bearing glass both sides is provided with sensing part, under load-bearing glass slides state, the sensing component that is in sensing part below is opened automatically and is in the solenoid valve on the arm under the load-bearing glass, but not the sensing component that is in the sensing part below is closed automatically and exposed the solenoid valve on the arm outside load-bearing glass.

Upper surface at air permeable plate offers the ventilation shallow slot.

The utility model compared with prior art, its advantage is by form the mode of thin layer air film below load-bearing glass, make load-bearing glass under the situation that does not increase thickness, intensity, get final product the heavier object of load-bearing, solved the problem of prior art glass deformation thus, also can conveniently adjust the measuring position when especially using by the thin layer air film by mobile load-bearing glass, and need not move whole worktable or measuring system, to bringing convenience property of operation.

Embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

See also Fig. 1～shown in Figure 5, a kind of measurement mechanism of worktable band air supporting glass, comprise the worktable 1 arranged along X axis and along Y-axis to the measuring system 2 that is suspended from the worktable top, certainly, measuring instrument 21 on the measuring system 2 is can be according to demand, can be designed to upper and lower moving or move left and right, not add at this and give qualification; Wherein:

This worktable 1 comprises:

One pedestal 11 offers a window 111a on the table top 111 of pedestal 11, be provided with air supporting track 111b on the two relative madial walls of this

window

111a, and 111b is provided with sensing part 111c along this air supporting track.

One load-bearing glass 12, it is embedded among the air supporting track 111b of window 111a of above-mentioned table top 111, and does not cover this window 111a fully, and the air supporting track 111b of this load-bearing glass 12 relative window 111a is slidably structure; The end of inlaying of above-mentioned load-bearing glass 12 both sides is provided with sensing part 121.

One air permeable plate 13, it is fixedly arranged on load-bearing glass 12 belows and blocks this window 111a fully; On this air permeable plate 13, offer a plurality of bleeder vents 131.Upper surface at air permeable plate 13 offers ventilation shallow slot 132, is used to dissolve the design that the air side pressure is done.

One snorkel 14, it is fixedly arranged on air permeable plate 13 belows; Along being responsible for 141 1 side horizontal expansions and constituting with the person in charge's 141 arms that communicate 142, each arm 142 is covered with whole air permeable plate 13 belows respectively to described snorkel 14, also all offers a plurality of venthole 142a on each arm 142 by a person in charge 141, complex root; Described each arm 142 respectively is equipped with solenoid valve 143 near the end of being responsible for 141, is used for cut-out or opens corresponding arm 142 gases of the person in charge's 141 supplies, and these solenoid valves 143 are controlled break-make by above-mentioned sensing component 111c.

One air compressor 15, it is communicated with the person in charge 141 of above-mentioned snorkel 14, provides air inlet to give the person in charge 14.

Above-mentioned measuring system 2 can adopt existing mature technology, does not give unnecessary details so do not add to give at this.

Wherein, when using after the above-mentioned assembly, open air compressor 15 earlier, air enters among the person in charge 141 of snorkel 14 through air compressor 15, provide corresponding arm air inlet by being responsible for 141, when mobile load-bearing glass 12 is adjusted the position, the sensing component 111c that wherein is in sensing part 121 belows opens automatically under sensing part 121 drives and is in the solenoid valve on the arm under the load-bearing glass, but not the sensing component 111c that is in sensing part 121 belows then closes automatically and exposes the solenoid valve on the arm outside load-bearing glass; Therefore, air then enters in the arm that has been in the solenoid valve unlatching, venthole by this arm upwards sprays again, and then most of air can continue upwards ejection by the bleeder vent that is positioned under the load-bearing glass 12 of air permeable plate 13, make load-bearing glass 12 belows produce upwards thin layer air film, make and can not cause self-deformation at the heavier object glass of carrying, and make slightly upwards float state of load-bearing glass 12, and then can realize that load-bearing glass 12 slides freely, so as long as promote load-bearing glass 12 gently, can make load-bearing glass 12 arrive the precalculated position in operator's measuring process.

The utility model design focal point is by form the mode of thin layer air film below load-bearing glass, make load-bearing glass under the situation that does not increase thickness, intensity, get final product the heavier object of load-bearing, solved the problem of prior art glass deformation thus, can conveniently adjust the measuring position by the thin layer air film when especially using by mobile load-bearing glass, and need not move whole worktable or measuring system, to bringing convenience property of operation.

The above, it only is the preferred embodiment of the measurement mechanism of a kind of worktable band of the utility model air supporting glass, be not that technical scope of the present utility model is imposed any restrictions, so every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any trickle modification, equivalent variations and modification that above embodiment did.
