Description

Technical Field

[0001] This utility model relates to the field of machining technology, and in particular to an adsorption plate for positioning in plate processing. Background Technology

[0002] In the machining of steel plates, it is often necessary to drill holes and mill them. Generally, the side of the steel plate is milled to create blind holes of a certain depth on the plate surface (front or back of the plate).

[0003] Before machining a steel plate, the machine tool needs to fix the steel plate in place. The conventional method is to clamp the steel plate on both sides using a vise before machining. While this method doesn't affect hole drilling, it does hinder milling the sides of the steel plate. This is because the vise obstructs the sides of the plate, preventing machining, and the plate needs to be repositioned before processing. This significantly reduces machining efficiency. Utility Model Content

[0004] The purpose of this invention is to solve the above-mentioned problems by designing an adsorption plate for positioning plate processing, which solves the problem that steel plates are inconvenient to process using existing clamping methods.

[0005] To achieve the above objectives, the technical solution of this utility model is an adsorption plate for positioning in plate processing, comprising a plate body, wherein the plate body has an adsorption area on its surface with a size adapted to the size of the plate to be processed, the adsorption area is filled with a plurality of crisscrossing and interconnected air extraction grooves, the adsorption area has at least one air extraction hole, the air extraction hole is connected to at least one of the air extraction grooves, the air extraction hole is externally connected to a vacuum mechanism, and at least one sealing ring is provided around the adsorption area.

[0006] Preferably, the adsorption zone has a plurality of annular first air extraction slots and a plurality of second air extraction slots connecting the plurality of first air extraction slots arranged sequentially from the central region outward.

[0007] Preferably, the first suction groove is rectangular in shape, and the second suction groove is diagonally distributed, forming a plurality of first suction grooves.

[0008] Preferably, there are four second air extraction slots, two of which are diagonally distributed and the other two are perpendicularly distributed.

[0009] Preferably, the periphery of the adsorption zone is provided with at least one annular sealing groove, and the sealing ring is disposed in the sealing groove.

[0010] Preferably, the air extraction hole extends to the back or side of the plate.

[0011] Preferably, the plate body has an air extraction channel, which is connected to the air extraction hole and extends to at least one side of the plate body.

[0012] Preferably, an air nozzle is provided at the air outlet of the air extraction channel.

[0013] Its advantages over existing technologies are: The adsorption plate of this invention has advantages such as simple structure and strong adsorption. After the plate to be processed is attached to the adsorption plate and in close contact with the sealing ring, air is then drawn outward by a vacuum mechanism. A negative pressure is generated at the air extraction hole, which draws air from the inner area of ​​the sealing ring between the plate to be processed and the adsorption plate to the outside through the air extraction groove. Since the air extraction groove covers the entire adsorption area, the adsorption area is large enough to firmly adsorb the plate to be processed. The adsorption force is stronger than that of conventional methods using multiple nozzles, and the contact between the plate to be processed and the adsorption plate is tighter and less prone to movement. At the same time, any surface of the plate to be processed other than the surface in contact with the adsorption plate can be processed without interference. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0017] Example 1 A preferred embodiment of this utility model proposes an adsorption plate for positioning in plate processing. The adsorption plate is used to adsorb and position the plate and has the advantages of strong adsorption force and wide adsorption surface.

[0018] For details, see Figures 1-2, the front surface of the plate body 1 of the suction plate is provided with a rectangular suction area, the shape of which is adapted to that of a plate member to be processed, but the specific size is slightly smaller than that of the plate member to be processed, so as to firmly suck the plate member.

[0019] A plurality of air suction grooves are fully distributed in the suction area, and are divided into two types: one type is an annular first air suction groove 101, and the first air suction groove 101 is rectangular; the other type is a linear second air suction groove 102.

[0020] A plurality of first air suction grooves 101 are provided and distributed sequentially from the central area of the suction area outwards, so that the first air suction grooves 101 can cover the entire suction area as much as possible. The distance between two adjacent first air suction grooves 101 is consistent, which ensures the uniformity of suction force.

[0021] Four second air suction grooves 102 are provided, wherein two of the second air suction grooves 102 are diagonally distributed, and sequentially connect the diagonal lines of the plurality of first air suction grooves 101, so that the plurality of first air suction grooves 101 are communicated with each other. The other two second air suction grooves 102 cross and are perpendicular to each other, such that the four second air suction grooves 102 are in a shape of a Chinese character "mi" (meaning rice), and meet at the central area of the suction area. The originally disconnected plurality of first air suction grooves 101 are communicated through the four second air suction grooves 102.

[0022] On the plate body 1 and located in the suction area, an air suction hole 103 is opened, and the air suction hole 103 extends along the thickness direction of the plate body 1. The air suction hole 103 is communicated with one of the first air suction grooves 101 or the second air suction groove 102, so that during air suction, air in the area around the air suction hole 103 flows into the air suction hole 103 along the first air suction grooves 101 and the second air suction grooves 102, and is finally pumped away.

[0023] In this embodiment, the air suction hole 103 is a blind hole. An air suction channel (not shown in the figure) is also opened in the plate body 1, and both ends of the air suction channel are respectively communicated with one side surface of the plate body 1 and the air suction hole 103. An air nozzle 3 is connected to the air outlet of the air suction channel, and the air nozzle 3 is in threaded connection with the air outlet. The air nozzle 3 is connected to an external vacuum pumping mechanism through an air pipe.

[0024] See Figure 1 , on the plate surface of the plate body 1 and located at the periphery of the suction area, two sealing grooves 104 are opened, the sealing grooves 104 are rectangular, and the two sealing grooves 104 are sequentially arranged from inside to outside.

[0025] See Figure 2 , a sealing ring 2 is arranged in each sealing groove 104. The sealing ring 2 is an elastic rubber sealing ring 2. When the plate member to be processed is attached to the suction plate, the sealing ring 2 is in close contact with the plate member to be processed, which enhances the sealing performance during vacuum pumping and prevents external air from entering the suction area.

[0026] Conventional adsorption designs use multiple nozzles arranged in an array to adsorb the board. However, this method uses point contact to adsorb the board, resulting in a small contact area, insufficient adsorption force, and difficulty in ensuring that the board does not shake.

[0027] In this application, when the workpiece to be processed is attached to the adsorption plate, the vacuum mechanism draws a vacuum outward through the air nozzle 3, generating negative pressure in the air extraction channel and at the air extraction hole 103. The air in the adsorption area will converge at the air extraction hole 103 along the first air extraction groove 101 and the second air extraction groove 102 and be drawn to the outside. Negative pressure will be generated between the surface of the workpiece to be processed and the area where the adsorption area is located, and the surface of the workpiece to be processed will be firmly adsorbed and fixed on the adsorption plate. This adsorption method has a large contact area between the workpiece to be processed and the adsorption plate, so the workpiece is not easy to move.

[0028] Example 2 like Figure 3 As shown, in this embodiment, no air extraction channel is provided. The air extraction hole 103 directly penetrates to the back of the plate 1 (i.e., the side away from the air extraction groove) and is then connected to the air nozzle 3. This design facilitates the machining of the hole.

[0029] Example 3 like Figure 4 As shown, in this embodiment, there is more than one extraction port 103 and extraction channel; there can be two, three, four, etc., with each extraction port 103 corresponding to one extraction channel. Each extraction channel is connected to its corresponding extraction port 103, and each extraction channel is connected to a vacuum mechanism. This allows for rapid extraction of air from each extraction slot within the adsorption zone in a short time.

[0030] Example 4 In this embodiment, the extraction grooves can also be configured as a crisscrossing mesh structure, instead of the rectangular structure in Embodiment 1. The mesh extraction grooves cover the entire adsorption area and are interconnected. The arrangement of the extraction holes 103 is the same as in Embodiment 1.

[0031] The above technical solution only embodies the preferred technical solution of this utility model. Any changes that may be made by those skilled in the art to certain parts of it embody the principle of this utility model and fall within the protection scope of this utility model.
