Description

Technical Field

[0001] The utility model relates to the technical field of negative pressure adsorption fixtures, and more specifically, to a negative pressure adsorption fixture of a multi-level gas path system. Background Art

[0002] Negative pressure adsorption refers to when gas flows between two areas of different pressures, the gas will flow from the high-pressure area to the low-pressure area. This flow will generate a negative pressure. When the negative pressure of the airflow acts on the solid surface, it will adsorb on the surface and fix the object. However, in the existing negative pressure adsorption of thin plates, most of them only have one air path system. When the plate and the air path are not completely covered, it is easy to fail to adsorb the thin plate. At the same time, the thin plate may also fall off due to shaking. Utility Model Content

[0031] The beneficial effect of adopting the above technical solution is that the second connecting plate 6 is located above the exhaust hole 4 and the vacuum groove 5. When the vacuum groove 5 and the upper part are evacuated through the exhaust hole 4, the first air groove 8 will adsorb the thin plate above.

[0032] A vacuum pump 11 is fixedly mounted on the bottom of the first connecting plate 2 , a mounting groove 12 is provided inside the base 1 , and the vacuum pump 11 is located directly below the air extraction hole 4 .

[0033] The beneficial effect of adopting the above technical solution is: the main function of the vacuum pump 11 is to evacuate the interior of the vacuum hole 4 by sealing it, and through the vacuum groove 5 and the second connecting plate 6 and the connecting hole 7 above, the pressure inside the first connecting plate 2 and the second connecting plate 6 changes, making the adsorption more firm.

[0034] A support plate 13 is fixedly installed on the side of the first connecting plate 2 away from the air extraction hole 4 , a telescopic rod 14 is fixedly installed above the support plate 13 , a spring 15 is sleeved on the outer side of the telescopic rod 14 , and a support pad 16 is fixedly installed above the spring 15 .

[0035] The beneficial effect of adopting the above technical solution is that the contact area between the thin plate and the device is increased by the support pad 16 contacting both sides of the thin plate, so that when the suction force is too large, the placed thin plate will be deformed.

[0036] There are multiple screw holes 3 , all of which are located inside the first connecting plate 2 . There are two bases 1 , both of which are located below the supporting plate 13 .

[0037] The beneficial effect of adopting the above technical solution is that the first connecting plate 2 is fixed above the base 1 by bolts and other tools inside the multiple support plates 13, which not only facilitates the installation, but also ensures the overall stability of the first connecting plate 2.

[0038] There are two connecting holes 7 and a plurality of first air grooves 8 . The plurality of first air grooves 8 are all located on the surface of the second connecting plate 6 , and the plurality of first air grooves 8 intersect each other perpendicularly.

[0039] The beneficial effect of adopting the above technical solution is that the multiple first air grooves 8 are respectively connected to the two connecting holes 7, thereby realizing a multi-level air path system, ensuring that when there is a place where the thin plate is not in contact, a strong adsorption effect can be achieved.

[0040] There are two mounting grooves 12 , and both mounting grooves 12 are located inside the two bases 1 .

[0041] The beneficial effect of adopting the above technical solution is that the two mounting grooves 12 enable the base 1 to be mounted on the brake workbench, so that the entire device has the effect of convenient installation and disassembly.

[0042] There are two support plates 13 , two telescopic rods 14 and two springs 15 , and the two support plates 13 , the two telescopic rods 14 and the two springs 15 are respectively located on the left and right sides of the first connecting plate 2 .

[0043] The beneficial effect of adopting the above technical solution is that in addition to the effect of supporting the thin plate by the two telescopic rods 14 and the two springs 15, when the thin plate is pressed downward, it remains parallel to the second connecting plate 6, so that when the thin plate and the second connecting plate 6 are fitted together, the adsorption area is more firm.

[0044] There are two support pads 16 , the height of the two support pads 16 is higher than the height of the second connecting plate 6 , and the material of the two support pads 16 is relatively soft.

[0045] The beneficial effect of adopting the above technical solution is that the two support pads 16 are in contact with the thin plate, and because of the soft material, they have a protective effect on the thin plate, preventing friction and scratches from affecting the aesthetics of the thin plate.

[0046] The working principle and use process of this utility model:

[0047] First, place the thin plate on the support pad 16 so that the thin plate and the second connecting plate 6 are parallel to each other, and then press the thin plate downward, wherein the spring 15 is stretched downward, so that the thin plate becomes stable and contacts with the upper side of the second connecting plate 6;

[0048] At this time, the vacuum pump 11 is started, and the air inside the second connecting plate 6 enters the vacuum groove 5 through the first gas groove 8 and the second gas groove 9 through the connecting hole 7, and is then extracted through the exhaust hole 4, so that the inside of the first gas groove 8, the second gas groove 9 and the vacuum groove 5 are kept in a vacuum state, and the air pressure inside and outside are different, so that the thin plate is adsorbed;

[0049] Finally, since the second connecting plate 6 is in contact with the thin plate over multiple areas, the contact area of ​​the thin plate becomes larger, so that when the adsorption force is greater, the thin plate can be ensured to be not easily deformed. At the same time, since the material of the second connecting plate 6 is relatively soft, the contact area of ​​the thin plate is protected to prevent the surface of the thin plate from being scratched.
