A porous vacuum chuck

Abstract

This utility model discloses a porous vacuum suction cup, including a suction cup with a matrix of suction holes on its top. The suction holes are connected by intersecting grooves. A sealing strip surrounds the matrix of suction holes. The suction cup also has independent second suction holes on its top, which communicate with the grooves. Each suction hole has a sealing ring. The sealing strip is fixed in a frame groove on the top of the suction cup, which communicates with the grooves. A tube head is located on one side of the suction cup, communicating with both suction holes. The advantages of this utility model compared to existing technologies are: each suction hole forms a small adsorption area with a sealing ring, and the matrix of suction holes forms a complete adsorption area; additionally, a second complete adsorption area is formed by the grooves connected within the sealing strip via the second suction hole. Simultaneous adsorption in both areas increases the adsorption area, resulting in a more stable dual adsorption effect and improved assurance for smooth processing.

Description

Technical Field

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

[0002] Since its introduction, the multi-hole vacuum chuck has been favored by many machining plants because it can quickly and effectively help CNC machining center operators to process plate-type parts.

[0003] However, users gradually discovered its shortcomings after using it, such as: 1. Poor adsorption effect and condition for thick plates, which means that if the plate is too thick, it cannot be pulled, which will cause the holes to close prematurely, and it is easy to cause problems such as flying away or scrapping; 2. High requirements for the flatness of the plate; 3. In order to reduce the requirements for the flatness of the plate, a rubber pad needs to be placed on the suction cup, which results in high rubber pad consumption costs. Utility Model Content

[0004] The purpose of this invention is to provide a porous vacuum suction cup to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] This utility model discloses a multi-hole vacuum suction cup, including a suction cup, the top of the suction cup is provided with a matrix of suction holes, the suction holes are connected by intersecting grooves, a sealing strip is provided around the matrix of suction holes, and the top of the suction cup is also provided with an independent suction hole, the suction hole being connected to the grooves.

[0007] As an improvement, the suction hole is equipped with a sealing ring.

[0008] As an improvement, the sealing strip is fixed in the frame groove at the top of the suction cup, and the frame groove is connected to the spacer groove.

[0009] As an improvement, a tube head is provided on one side of the suction cup, and the tube head is connected to suction hole one and suction hole two.

[0010] The advantages of this invention compared to existing technologies are as follows: Each suction hole forms an adsorption zone with a sealing ring, and the matrix-distributed suction holes form an overall adsorption area; in addition, a second overall adsorption area is formed by the interconnected slots within the sealing strip via the second suction hole, which reduces the requirements for the flatness of the board material and eliminates the need for rubber pads. Simultaneous adsorption in both overall adsorption areas increases the adsorption area, resulting in a more stable dual adsorption effect and improved assurance for smooth processing.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] In the description of the embodiments of this utility model, it should be noted that if terms such as "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" appear, the indicated orientation or positional relationship is based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship that the utility model product is usually placed in during use. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0021] Furthermore, the terms "first," "second," and "third" are used only for distinguishing descriptions and should not be interpreted as indicating or implying relative importance. The use of terms such as "horizontal," "vertical," and "suspended" does not imply that the component must be absolutely horizontal or suspended, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," not that the structure must be perfectly horizontal, but can be slightly tilted.

[0022] In the description of the embodiments of this utility model, the terms "multiple" or "several" refer to at least two.

[0023] In the description of the embodiments of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0025] This embodiment discloses a multi-hole vacuum suction cup, including a suction cup 1. The top of the suction cup 1 is provided with a matrix of suction holes 2. The suction holes 2 are characterized by having intersecting and interconnected spacing grooves 3. A sealing strip 4 is provided around the matrix of suction holes 2 of the suction cup 1. The top of the suction cup 1 is also provided with an independent suction hole 5, which is connected to the spacing grooves 3.

[0026] The suction hole 2 is equipped with a sealing ring 6.

[0027] The sealing strip 4 is fixed in the frame groove 7 at the top of the suction cup 1, and the frame groove 7 is connected to the spacer groove 3.

[0028] The suction cup 1 has a tube head 8 on one side, and the tube head 8 is connected to suction hole 2 and suction hole 5.

[0029] In practical implementation, a plate is attached to the top of suction cup 1, and the tube head 8 is connected to the suction pump. Suction is initiated, and each suction hole 2 forms an adsorption zone with a sealing ring 6. The matrix-distributed suction holes 2 form an overall adsorption area.
