Description

Technical Field

[0001] This utility model relates to the field of machining tools, specifically a vacuum suction cup device. Background Technology

[0002] When machining sheet metal, it is necessary to fix the sheet metal. The traditional method of fixing the sheet metal is to use a pressure plate or a vacuum suction cup.

[0003] The method of fixing the sheet metal with a pressure plate has the advantages of not requiring additional auxiliary devices, being relatively easy to clamp, and having a low cost. However, since the pressure plate needs to press down on the sheet metal, it may damage the sheet metal, occupy the space of the sheet metal, and the pressure plate forms an obstruction. Therefore, it is impossible to fully process the upper surface of the sheet metal. Moreover, the operator needs to be careful that the machine tool cutter does not collide with the pressure plate, making the operation inconvenient.

[0004] Among them, the method of fixing the board with a vacuum suction cup is relatively convenient and quick compared to the method of fixing with a pressure plate. It will not damage the board, can stably fix the board, and will not occupy the space of the board. For example, the prior art of suction cup clamp in Chinese patent application No. 202223480565.3, which is entitled "Suction Cup Clamp", achieves stable clamping of the adsorbed object. However, the vacuum generated by the vacuum generator has the problems of high noise, poor pressure holding effect, easy clogging, and more smoke, which is unsanitary and affects the working environment. Utility Model Content

[0005] In view of the above-mentioned shortcomings in the related technologies, the purpose is to provide a vacuum suction cup device to solve the technical problems of poor pressure holding effect, easy clogging, and excessive smoke generation, which are unsanitary and affect the working environment.

[0006] The technical solution to achieve the objective is: a vacuum suction cup device, comprising:

[0007] The suction cup body comes into contact with the plate-like object;

[0008] A manual sliding valve, connected to the suction cup body, is used to regulate airflow;

[0009] The first pipeline has one end connected to the manual sliding valve;

[0010] A gas storage tank is connected to the other end of the first pipeline;

[0011] The second pipeline is connected at one end to the gas storage tank;

[0012] And a vacuum pump, connected to the other end of the second pipeline, for extracting air from the gas storage tank.

[0013] Furthermore: the suction cup body includes: a disc body, with the hand-operated valve connected to the side wall;

[0014] At least one adsorption area is disposed on one side surface of the disk body for contact with the plate-like object;

[0015] A gas channel is provided inside the disc body, with one end connected to the manual sliding valve and the other end running along the disc body, penetrating one side surface of the disc body, and communicating with the adsorption area.

[0016] Furthermore, the disc body has a square plate-like structure.

[0017] Furthermore, the adsorption area is located in the middle of the disk body, and the center point of the adsorption area is the same as the center point of the disk body.

[0018] Furthermore: the adsorption region includes: an airflow groove;

[0019] A sealing groove is provided around the airflow groove and spaced apart from the airflow groove;

[0020] And a sealing strip, one end of which is embedded in the sealing groove and the other end protrudes from the sealing groove, forming a space between the airflow groove and the disc body.

[0021] Furthermore: the airflow groove includes: a plurality of first grooves, the first grooves being arc-shaped grooves, the first grooves being arranged around the center point, with the center point as the center, forming a plurality of layers, with the layers spaced apart from each other;

[0022] And several second grooves, which are elongated structures, are arranged around the center point with the center point as the center, and are connected to the first groove, forming a mesh structure together with the first groove.

[0023] Furthermore: the sealing groove includes: a plurality of third grooves, spaced apart, wherein the third grooves are arc-shaped grooves;

[0024] And several fourth grooves, which are U-shaped grooves, are spaced apart from each other. One end of each fourth groove is connected to the third groove, and the other end extends toward the gas channel and is spaced apart from the airflow groove.

[0025] Furthermore, the gas channel has an "L" shaped structure, with one end connected to the hand slide valve and the other end located at the center point, communicating with the space.

[0026] Furthermore, it also includes: a plurality of through holes, spaced apart on the disc body, located outside the adsorption area, and spaced apart from the adsorption area.

[0027] Furthermore, it also includes: a plurality of positioning pins, spaced apart on the disc body, located outside the adsorption area, spaced apart from the adsorption area, and spaced apart from the through hole.

[0028] The above technical solution has the following beneficial effects: A vacuum suction cup device, compared with related technologies, is provided with a suction cup body, a manual sliding valve, a first pipeline, a gas storage tank, a second pipeline and a vacuum pump;

[0029] When the suction cup body contacts the plate-shaped object, the vacuum pump activates, drawing air from the air tank through the second pipeline, causing the air pressure inside the air tank to drop below atmospheric pressure, creating a vacuum in the air tank. Simultaneously, air in the first pipeline is also drawn in, creating an adsorption force at the suction cup body. This allows the plate-shaped object to be adsorbed and fixed. A manual sliding valve is included to disconnect or connect the suction cup body and the first pipeline.

[0037] To make the content easier to understand, the following detailed description is provided with reference to specific embodiments and accompanying drawings;

[0038] A vacuum suction cup device solves the technical problems of poor pressure holding effect, easy clogging, and excessive smoke generation in related technologies, which are unsanitary and affect the working environment. This device can be manufactured and used, achieving relatively better pressure holding effect, reducing the probability of clogging, and providing relative hygiene, thus protecting the working environment. The overall concept is as follows:

[0039] Implementation

[0040] like Figure 1 As shown; a vacuum suction cup device, comprising:

[0041] The suction cup body 10 is in contact with the plate-shaped object 100;

[0042] A manual sliding valve 20 is connected to the suction cup body 10 and is used to regulate the airflow.

[0043] The first pipeline 30 is connected at one end to the manual sliding valve 20;

[0044] The gas storage tank 40 is connected to the other end of the first pipeline 30;

[0045] The second pipeline 50 is connected at one end to the gas storage tank 40;

[0046] And a vacuum pump 60, which is connected to the other end of the second pipeline 50, for extracting air from the gas storage tank 40;

[0047] Specifically, during implementation, the plate-shaped object 100 is placed on the suction cup body 10, and the vacuum pump 60 is activated. Air is drawn from the air storage tank 40 through the second pipeline 50, making the air pressure in the air storage tank 40 lower than atmospheric pressure, and the air storage tank 40 is in a vacuum state. While the air storage tank 40 is being evacuated, the air in the first pipeline 30 is also drawn in, forming an adsorption force at the suction cup body 10. This allows the plate-shaped object 100 to be adsorbed through the suction cup body 10, and the plate-shaped object 100 is fixed in place. A manual sliding valve 20 is provided, which can disconnect the suction cup body 10 from the first pipeline 30 or connect the suction cup body 10 from the first pipeline 30. At the same time, the airflow can be adjusted, thereby adjusting the adsorption force of the suction cup body 10 on the plate-shaped object 100. The system offers relatively good flexibility, relatively low noise, relatively good pressure holding effect, reduces the chance of blockage, is relatively hygienic, and protects the working environment.

[0048] Another implementation method:

[0049] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown; in implementation, the suction cup body 10 includes: a disc body 11 with the hand slide valve 20 connected to its side wall; at least one adsorption area 12 disposed on one side of the disc body 11 for contacting the plate-shaped object 100; and a gas channel 13 disposed inside the disc body 11, one end of which is connected to the hand slide valve 20, and the other end of which runs along the disc body 11, penetrates one side surface of the disc body 11, and communicates with the adsorption area 12.

[0050] The disc body 11 is a square plate structure with a regular shape, which is easy to process and manufacture, and is relatively aesthetically pleasing.

[0051] The adsorption region 12 is one in number and is located in the middle of the disk body 11. The center point of the adsorption region 12 is the same as the center point of the disk body 11, which helps the adsorption region 12 to fully utilize the surface of the disk body 11 (e.g., by...). Figure 3 As shown, the area of ​​the adsorption region 12 is approximately 80% of the area of ​​the disk 11, which is relatively aesthetically pleasing and allows for reliable contact with the plate 100.

[0052] The adsorption area 12 includes: an airflow groove 12-1; a sealing groove 12-2, which surrounds the airflow groove 12-1 and is spaced apart from the airflow groove 12-1; and a sealing strip 12-3, one end of which is embedded in the sealing groove 12-2 and the other end protrudes from the sealing groove 12-2, forming a space 12-4 between the airflow groove 12-1 and the disk body 11.

[0053] The airflow channel 12-1 includes: a plurality of first channel channels 12-11, each of which is an arc-shaped channel, arranged around the center point to form several layers with the center point as the center, and the layers are spaced apart; and a plurality of second channel channels 12-12, which are elongated structures, arranged around the center point to the center, communicating with the first channel channels 12-11, and together with the first channel channels 12-11 to form a mesh structure; thus forming a mesh structure airflow channel, which is conducive to air circulation, reduces the probability of blockage, and results in relatively low noise;

[0054] The sealing groove 12-2 includes: a plurality of third grooves 12-21, which are spaced apart and are arc-shaped grooves; and a plurality of fourth grooves 12-22, which are U-shaped grooves, which are spaced apart and have one end connected to the third grooves 12-21, and the other end extending toward the gas channel 13 and spaced apart from the airflow groove 12-1.

[0055] The sealing groove 12-2 is set around the airflow groove 12-1. The sealing strip 12-3 is a rubber strip. After being inserted into the sealing groove 12-2, it forms a space 12-4 between the airflow groove 12-1 and the disc 11. When the vacuum pump 60 is evacuating, the space 12-4 is in a vacuum state, generating an adsorption force that can adsorb the plate-shaped object 100. At the same time, the sealing strip 12-3 can not only form a seal, but also contact and support the plate-shaped object 100 without damaging it.

[0056] The gas channel 13 has an "L" shaped structure, with one end connected to the hand slide valve 20 and the other end located at the center point, communicating with the space 12-4. With the gas channel 13 provided, when the vacuum pump 60 is drawing a vacuum, the space 12-4 can be drawn through the gas channel 13, making the space 12-4 a vacuum state, generating an adsorption force to adsorb and fix the plate-shaped object 100. The air circulation is relatively smooth, reducing the chance of blockage and the noise is relatively low.

[0057] Another implementation method:

[0058] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown; in practice, it also includes: a number of through holes 14, which are spaced apart on the disk body 11 and located outside the adsorption area 12, spaced apart from the adsorption area 12; the number of through holes 14 is four, which is conducive to inserting bolts to fix the suction cup body 10 on the worktable, and the installation and disassembly are relatively convenient.

[0059] Another implementation method:

[0060] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown; in practice, it also includes: a number of positioning pins 15, which are spaced apart on the disc body 11, located outside the adsorption area 12, spaced apart from the adsorption area 12, and spaced apart from the through hole 14; the positioning pins 15 are provided, such as cylindrical pins, and there are eight positioning pins 15. When the plate 100 contacts the sealing strip 12-3, the positioning pins 15 can help support the plate 100, and the structural reliability is relatively good;

[0061] Another implementation method:

[0062] like Figure 1 As shown; in practice, the hand slide valve 20 is a commonly used structure in the prior art. The hand slide valve 20 can disconnect the suction cup body 10 and the first pipe 30 to block the air flow, or connect the suction cup body 10 and the first pipe 30 to allow air to flow. At the same time, by adjusting the opening and closing size of the hand slide valve 20, the air flow can be adjusted, thereby adjusting the suction force of the suction cup body 10 on the plate 100.

[0063] The first pipe 30 is used to connect the suction cup body 10 and the air tank 40. The first pipe 30 is composed of a flexible hose, a straight metal pipe, a bent metal pipe, a metal flange, etc., which is conducive to air circulation, relatively hygienic, and protects the working environment.

[0064] The gas storage tank 40 is a commonly used structure in the prior art, used to buffer gas pressure fluctuations and ensure that the gas pressure remains stable (for more than 0.5 hours in the pressure holding state, the vacuum pump 60 stops operating in the pressure holding state, thus extending the service life of the vacuum pump 60), and the pressure holding effect is relatively good.

[0065] The second pipeline 50 is used to connect the gas storage tank 40 and the vacuum pump 60. The second pipeline 50 is composed of straight metal pipes, bent metal pipes, metal flanges, etc., which is conducive to air circulation, relatively hygienic, and protects the working environment.

[0066] The vacuum pump 60 is a common structure in the prior art, used to extract air from the gas storage tank 40, so that the gas pressure in the gas storage tank 40 is lower than atmospheric pressure, and the gas storage tank 40 is in a vacuum state, which is conducive to generating adsorption force at the suction cup body 10 to adsorb the plate-shaped object 100.

[0067] The board-shaped object 100 refers to a board material, such as: square board material, round board material, etc.;

[0068] Those skilled in the art, upon seeing the disclosed content, can directly and without doubt know how to set up the hand slide valve 20, the first pipeline 30, the gas storage tank 40, the second pipeline 50, and the vacuum pump 60, without needing to expend creative effort or conduct excessive experimentation.

[0069] The working principle is as follows: The plate-shaped object 100 is placed on the suction cup body 10. The vacuum pump 60 is activated, and air is drawn from the air storage tank 40 through the second pipe 50, so that the air pressure in the air storage tank 40 is lower than atmospheric pressure, and the air storage tank 40 is in a vacuum state. While the air storage tank 40 is being evacuated, the air in the first pipe 30 is also drawn in, forming an adsorption force at the suction cup body 10, so that the plate-shaped object 100 can be adsorbed through the suction cup body 10. A manual sliding valve 20 is provided, which can disconnect the suction cup body 10 from the first pipe 30 or connect the suction cup body 10 from the first pipe 30. At the same time, the airflow can be adjusted, thereby adjusting the adsorption force of the suction cup body 10 on the plate-shaped object 100. The flexibility of use is relatively good, and the plate-shaped object 100 can be fixed.
