Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
Example (b): the utility model provides a panel vacuum clamp, as shown in fig. 1 and fig. 2, including adsorption plate 1, 1 upper surface of adsorption plate is equipped with the protruding 11 of a plurality of neatly arranged's square, an aspirating hole 12 has been seted up on the protruding 11 of part square, aspirating hole 12 evenly distributed is on a plurality of square are protruding 11, the drill way department of aspirating hole 12 is equipped with second sealing washer 4, be equipped with thickness on the adsorption plate 1 and be greater than the first sealing washer 2 of the protruding 11 height of square, first sealing washer 2 encircles a plurality of square are protruding 11 wherein, the geometric center of adsorption plate 1 has seted up and has taken out hole 32 in advance, the diameter of taking out hole 32 in advance is greater than aspirating hole 12, 1 downside of adsorption plate is equipped with exhaust tube 3, one side that adsorption plate 1 was kept away from to exhaust tube 3 is connected with aspiration pump 31, aspirating hole 12 all is. When the plate needs to be fastened, the staff places the plate on first sealing washer 2, and whether the inspection plate covers first sealing washer 2 completely, then start aspiration pump 31, because the hole 32 aperture of taking out in advance is great, the hole 32 of taking out in advance is evacuated the air between the inboard plate of sealed pad 52 and the adsorption plate 1 fast, make the plate pushed to adsorption plate 1 by the quick pressure of atmosphere, and contact with square arch 11 and second sealing washer 4, second sealing washer 4 receives the extrusion messenger and takes place elastic deformation and easily laminate with the plate, thereby aspiration hole 12 continuously bleeds and fixes the plate, the laminating degree in plate and 12 orifices of aspiration hole has been increased, the lax possibility of plate has been reduced, and the processing quality is improved.
As shown in fig. 3, first sealing washer 2 can be dismantled with adsorption plate 1 and be connected, the adsorption tank 21 that extends along the 2 outlines of first sealing washer is seted up to first sealing washer 2 towards the one side of adsorption plate 1, thereby compress tightly first sealing washer 2 and adsorption plate 1 and extrude the air in the adsorption tank 21 when the staff installs first sealing washer 2 to adsorption plate 1, utilize atmospheric pressure to continue to extrude first sealing washer 2 on adsorption plate 1, make first sealing washer 2 play sealed effect, the staff only need can communicate adsorption tank 21 and atmospheric pressure with the perk of 2 one end of first sealing washer when dismantling the sealing washer, easily take off first sealing washer 2, first sealing washer 2 easily dismantles the installation, it facilitates to change ageing first sealing washer 2 for the staff.
As shown in fig. 4, the upper cover of the adsorption plate 1 is provided with a positioning cover plate 5, the positioning cover plate 5 is provided with a positioning groove 51 adapted to the plate, when a worker clamps the plate on the clamp, the plate is only required to be placed into the positioning groove 51, the worker is not required to align and adjust the position of the plate, convenience is provided for the worker, the positioning cover plate 5 is provided with a sealing gasket 52, when the clamped plate is smaller than the first sealing ring 2, the sealing gasket 52 seals the redundant air suction holes 12, and therefore the plate cannot be tightly sucked due to the leakage of the redundant air suction holes 12.
As shown in fig. 4 and 5, the lower end of the adsorption plate 1 is fixedly and hermetically connected with a partition plate 13, the partition plate 13 is provided with a plurality of grooves 131, the grooves 131 are communicated with the extraction holes 12, and the grooves 131 are communicated with the extraction pipe 3. Because a plurality of holes communicated with the air exhaust holes 12 are usually drilled below the adsorption plate 1 of the existing vacuum clamp to form an air exhaust pipe 3, when the method is used, if the hole diameter is too large, the side length of time required by an air exhaust pump 31 to exhaust air in the pipeline is long, and the time for fixing the plate and the clamp is prolonged; if the diameter of the drill bit is too small, the drill bit is easy to break when a deep hole is drilled, the manufacturing cost of the special drill bit is high, and the manufacturing cost is increased, so that the partition plate 13 is provided with the groove 131 and is hermetically connected with the adsorption plate 1 through sealing means such as industrial glue and the like to form an air suction pipeline, and the processing cost is saved.
As shown in figure 5, a pressure gauge 6 is arranged at the position of the exhaust tube 3, and a worker monitors whether the vacuum clamp breaks down or not by referring to the indication number of the pressure gauge 6 so as to process in time.
The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
