Description

Technical Field

[0002] A vacuum adsorption table is an industrial equipment, usually used to fix and process thin plate materials or flat workpieces. It uses vacuum technology to form a vacuum on the work surface so that the workpiece can be firmly fixed on the adsorption table, so as to carry out precise processing, cutting, grinding or other process operations.

[0003] The vacuum adsorption table consists of the following main parts: the surface of the adsorption table, which is usually made of a flat metal, plastic or other wear-resistant material, and this surface is usually arranged with channels or tiny pores; the vacuum system, which is connected to the vacuum pipes and pumps under the surface of the adsorption table. The vacuum system forms a negative pressure area above the surface of the adsorption table through these channels or pores.

[0004] The adsorption holes of existing vacuum adsorption fixtures are usually provided with a valve body mechanism, which automatically closes the adsorption holes not covered by materials to save energy consumption of the vacuum pump. However, the existing valve body mechanism usually needs to be screwed into the adsorption holes one by one, and installation and disassembly are time-consuming and labor-intensive.

[0024] In order to more clearly and completely illustrate the technical solution of the present invention, the present invention is further described below in conjunction with the accompanying drawings.

[0025] Please refer to Figure 1-Figure 3 The utility model proposes a high-gloss flat vacuum adsorption fixture, comprising a vacuum chamber plate 1, a mounting base plate 2 and a porous adsorption plate 3. A clamping hole is provided on the top of the mounting base plate 2, and the porous adsorption plate 3 is fixedly installed in the clamping hole. The mounting base plate 2 is fixedly connected to the vacuum chamber plate 1 by a plurality of bolts. A plurality of adsorption holes 4 are provided on the top of the porous adsorption plate 3. Notches 5 are provided on both the front and rear sides of the porous adsorption plate 3, and a valve body mechanism 6 is provided in the adsorption hole 4.

[0026] It should be noted that the notch 5 has a foolproof function to prevent the material to be adsorbed from being placed in the wrong direction. The multiple adsorption holes 4 are arranged in a specific manner, as shown in the attached manual. Figure 1 As shown, some areas on the top of the porous adsorption plate 3 do not have adsorption holes 4, avoiding weak areas of the material to be adsorbed to prevent vacuum suction from damaging the material.

[0027] It is further explained that the vacuum chamber plate 1, the mounting base plate 2 and the porous adsorption plate 3 are made of non-magnetic or weakly magnetic materials, such as stainless steel, aluminum alloy and titanium alloy, to prevent attraction with the magnetic plate 13 causing displacement of the magnetic plate 13 and thus blocking the adsorption holes 4, resulting in the inability to perform vacuum adsorption operations.

[0028] The valve body mechanism 6 includes a valve core 7, a wide vertical groove 8 is provided on the top of the valve core 7, a narrow vertical groove 9 is provided at the bottom of the wide vertical groove 8, the wide vertical groove 8 is connected with the narrow vertical groove 9 through an inclined groove, a through hole 10 is provided on the bottom inner wall of the narrow vertical groove 9, a supporting spring 11 is fixedly installed on the bottom inner wall of the narrow vertical groove 9, a hemisphere 12 is fixedly installed on the top of the supporting spring 11, a magnetic plate 13 is provided on the hemisphere 12, and an electromagnetic plate 14 is provided in the vacuum chamber plate 1.

[0029] It should be noted that when the vacuum adsorption operation is performed, a large number of cavities enter the adsorption holes 4 that are not covered by the material, thereby generating pressure on the top of the magnetic plate 13, driving the magnetic plate 13 and the hemisphere 12 to move downward, so that the hemisphere 12 is blocked in the vertical groove 9, realizing the automatic sealing function.

[0030] like Figure 2 As shown, the same annular limit plate 15 is fixedly installed on the inner wall of the wide vertical groove 8, and the bottom of the annular limit plate 15 abuts against the top of the magnetic plate 13. The setting of the annular limit plate 15 limits the upward displacement of the magnetic plate 13 to prevent the repulsive force between the magnetic plate 13 and the electromagnetic plate 14 from being too large, which will cause the support spring 11 to be excessively deformed and damaged.

[0031] A plurality of inner grooves are formed on the outer side of the valve core 7 , and abutment plates 16 are slidably mounted in the inner grooves. The plurality of abutment plates 16 are arranged in a circular array.

[0032] Two guide plates 17 are fixedly installed on the inner wall of one side of the internal groove, and two guide grooves are provided on one side of the abutment plate 16. The guide plate 17 is slidably installed in the corresponding guide grooves. An intermediate groove is provided on one side of the abutment plate 16. The same limit spring 18 is fixedly installed between the inner wall of one side of the intermediate groove and the inner wall of one side of the corresponding internal groove. The abutment plate 16 and the limit spring 18 make the valve core 7 tightly clamped with the adsorption hole 4, thereby improving the stability of the valve body mechanism installation 6.

[0033] like Figure 3 As shown, an annular groove 19 is provided at the bottom of the mounting base plate 2 , the annular groove 19 is connected to the snap-in hole, and a sealing strip is filled in the annular groove 19 to improve the sealing performance of the connection between the mounting base plate 2 and the porous adsorption plate 3 .

[0034] like Figure 3 and Figure 4 As shown, a chamber 22 is provided in the vacuum chamber plate 1, and two support columns 20 are fixedly installed on the top of the chamber 22. Two circular grooves are provided on the top of the support columns 20. Two circular plates 21 are fixedly installed on the top inner wall of the porous adsorption plate 3. The circular plates 21 are movably snapped into the corresponding circular grooves. Through the cooperation of the support columns 20, the circular grooves and the circular plates 21, the porous adsorption plate 3 is supported.

[0035] like Figure 1and Figure 2 As shown, the top of the wide vertical groove 8 is connected to the outside, the through hole 10 is connected to the chamber 22, the hemispherical body 12 cooperates with the inclined groove and the narrow vertical groove 9 respectively, and an air path hole 23 is provided on the inner wall of one side of the chamber 22. The vacuum pump is connected to the chamber 22 through the air path hole 23 to realize the vacuum pumping function.

[0036] like Figure 4 As shown, the bottom of the electromagnetic plate 14 is fixedly connected to the bottom inner wall of the chamber 22 , and a circuit connected to the outside is provided on the bottom inner wall of the chamber 22 , and the circuit is connected to the electromagnetic plate 14 to provide external power to the electromagnetic plate 14 .

[0037] The working principle of the utility model is as follows: the valve body mechanism 6 is inserted into the adsorption hole 4, the abutment plate 16 is received in the internal groove on the inner wall of the adsorption hole 4, and the limit spring 18 is compressed, so as to realize the stable clamping connection between the valve core 7 and the adsorption hole 4. When the valve body mechanism 6 needs to be maintained or replaced, the electromagnetic plate 14 is energized so that the electromagnetic plate 14 generates a magnetic field with the same magnetic pole as the magnetic plate 13. The same poles repel each other so that the magnetic plate 13 obtains an upward driving force, so that the valve body mechanism 6 pops out of the adsorption hole 4, making it easy to remove the valve body mechanism 6.

[0038] Of course, the present utility model may have many other implementations. Based on the present implementation, other implementations obtained by ordinary technicians in this field without any creative work are all within the scope of protection of the present utility model.
