Description

TECHNICAL FIELD

[0001] The application relates to the technical field of machining equipment, in particular to a quick positioning and adsorbing mechanism. BACKGROUND

[0002] As a kind of precision machining equipment, the precision carving machine is widely used in modern manufacturing industry, especially in the fields of electronics and automobile parts, and the demand for machining of complex shape and high-precision parts is increasing. However, with the improvement of material performance and the increasing requirement of machining precision, the traditional workpiece fixing method has been difficult to meet the efficient and non-damaging machining demand. Especially for high hardness materials such as PA+glass fiber, the traditional method often causes scratches or deformation on the surface of the workpiece, affecting the quality and production efficiency of the final product.

[0003] At present, in order to realize the stable fixation of workpiece, the industry usually adopts the mechanical pressing method, such as using clamps or pressing plates to fix the workpiece. Although this fixing method is simple and effective, it is easy to cause scratches or local deformation on the surface of the workpiece when processing high hardness materials, especially in the case of frequent replacement of workpieces, this problem is more serious. In addition, some technologies also use adhesives or magnetic adsorption methods, but these methods also have certain limitations, such as the adhesives may contaminate the workpiece, and the magnetic adsorption is not suitable for non-ferromagnetic materials.

[0004] In the existing workpiece fixing method, mechanical pressing is one of the most common means, although it can provide enough clamping force, but it causes great damage to the surface of the workpiece, especially in the machining process of high hardness materials. In addition, since mechanical pressing relies on physical contact, the shape and size change of the workpiece will affect the clamping effect, increasing the operation difficulty and cost. Therefore, how to ensure the clamping force while avoiding the damage to the surface of the workpiece, improving the machining efficiency and quality, has become a technical problem to be solved. CONTENT OF THE INVENTION

[0005] The purpose of the application is to provide a quick positioning and adsorbing mechanism.

[0006] The above technical purpose of the application is realized by the following technical scheme: a quick positioning and adsorbing mechanism, comprising a bottom die, the bottom die is provided with a mounting groove for embedding and mounting a workpiece to be machined, the bottom die is hollow and provided with an air passage, the air passage and the mounting groove are in communication, the air passage is connected with a gas pressure adjusting device to adjust the air pressure in the mounting groove.

[0007] By adopting the technical scheme, the mounting groove on the bottom die can be accurately fitted with the workpiece to be processed, and a stable mounting position is provided for the workpiece, effectively preventing the workpiece from moving during processing. The bottom die is hollowly provided with a ventilation passage, the ventilation passage is in communication with the mounting groove and connected with the air pressure adjusting device, and the air pressure in the mounting groove can be flexibly adjusted. The adsorption force can be accurately controlled according to the characteristics and processing requirements of different workpieces. When the workpiece needs to be adsorbed, the appropriate negative pressure can be generated by adjusting the air pressure, so that the workpiece is firmly adsorbed in the mounting groove, and the stability during processing is ensured. When the workpiece to be processed needs to be disassembled and taken out, the workpiece to be processed is pushed out of the mounting groove by air pressure, and the operator can conveniently store the workpiece. The adjustable air pressure adsorption method is more flexible and efficient than the traditional clamping method, which not only reacts quickly and can realize rapid positioning and adsorption, greatly improving the production efficiency, but also can avoid damage to the workpiece caused by improper clamping force. At the same time, the generality and applicability of the mechanism are strong, and it can adapt to workpieces of different shapes and sizes and various processing requirements.

[0008] Optionally, a main ventilation groove is recessed in the bottom of the mounting groove, and the main ventilation groove and the ventilation passage are in communication.

[0009] By adopting the technical scheme, the main ventilation groove can further enhance the gas flow between the mounting groove and the ventilation passage. When the air pressure adjusting device works, the gas can flow more smoothly between the ventilation passage and the mounting groove, so that the air pressure adjustment is more rapid and accurate, so that the adsorption force on the workpiece can be adjusted more quickly to realize rapid positioning and adsorption. The main ventilation groove can make the air pressure more evenly distributed in the mounting groove. When negative pressure is generated to adsorb the workpiece, the adsorption force on each part of the workpiece is more uniform, avoiding the situation that the workpiece is locally deformed or unstable due to uneven adsorption force, greatly improving the processing precision and the stability of the workpiece installation. The existence of the main ventilation groove also increases the contact area with the workpiece, further enhancing the adsorption effect and ensuring that the workpiece is firmly fixed in the mounting groove during processing.

[0010] Optionally, a plurality of secondary ventilation grooves are recessed in the bottom of the mounting groove, and the secondary ventilation grooves and the main ventilation groove are in communication.

[0011] By adopting the above technical scheme, the secondary ventilation grooves in communication with the main ventilation groove are arranged, and the efficiency and uniformity of gas flow are further improved. The secondary ventilation grooves and the main ventilation groove jointly act, so that the gas entering from the ventilation channel can be more quickly diffused into the entire mounting groove. Whether in the process of forming negative pressure for adsorption or in the process of adjusting air pressure, more sensitive response can be realized, and the working efficiency of the mechanism is greatly improved. At the same time, the numerous secondary ventilation grooves increase the contact points with the workpiece, so that the adsorption force is distributed more finely and uniformly, and the stability of the workpiece in the mounting groove is further enhanced, effectively preventing the workpiece from appearing slight displacement or shaking in the machining process, thereby ensuring the machining precision. In addition, the combined design of the secondary ventilation grooves and the main ventilation groove also increases the reliability and durability of the mechanism. Even if part of the ventilation grooves are blocked, other ventilation grooves can still function to ensure the normal operation of the mechanism.

[0012] Optionally, the ventilation channel is provided with a connecting piece at the channel opening away from the side of the mounting groove, for connecting with an air pressure adjusting device.

[0013] By adopting the above technical scheme, the connecting piece is arranged at the channel opening away from the side of the mounting groove of the ventilation channel, which greatly improves the versatility and expandability of the rapid positioning and adsorption mechanism. The connecting piece enables the mechanism to be conveniently connected with various adjusting devices, and the appropriate adjusting device can be flexibly selected according to different machining requirements and working scenes, thereby further enriching the adjustment mode and range of air pressure of the mechanism. For example, a more precise air pressure sensor can be connected to monitor the air pressure change in the mounting groove in real time, so as to realize more precise adsorption force control; or a filtering device with special functions can be connected to ensure that the gas entering the ventilation channel is clean and prevent impurities from damaging the mechanism. At the same time, the presence of the connecting piece also makes the installation and maintenance of the mechanism more convenient. When the adjusting device needs to be replaced or repaired, only the disassembly and connection operations need to be performed through the connecting piece, without the need to perform complex modification on the entire mechanism, thereby reducing the use cost and maintenance difficulty.

[0014] Optionally, the bottom die is provided with a positioning groove for embedding and mounting the connecting piece.

[0015] By adopting the above technical scheme, the installation position of the connecting piece can be ensured to be accurate and stable. The positioning groove provides a special installation space for the connecting piece, so that the connecting piece will not be displaced or loosened during work due to external force, thereby ensuring the reliability of connection with other adjusting devices. This design helps to maintain the sealing of the air passage and prevent gas leakage, thereby ensuring the accuracy of air pressure adjustment and the adsorption effect on the workpiece. At the same time, the presence of the positioning groove makes the appearance of the entire mechanism more neat and compact, reducing the space occupation and clutter caused by the random installation of the connecting piece. During installation and maintenance, the positioning groove also facilitates the operator to quickly and accurately find the installation position of the connecting piece, thereby improving the work efficiency. In addition, the positioning groove can also protect the connecting piece to some extent, reducing the risk of collision and damage from the outside.

[0016] Optionally, a plurality of mounting holes are arranged on the bottom die.

[0017] By adopting the above technical scheme, a plurality of mounting holes are arranged on the bottom die, which provides convenience for the installation and fixation of the quick positioning and adsorption mechanism. These mounting holes can be used to firmly install the bottom die on the processing equipment or workbench, ensuring that the bottom die will not move during processing, thereby ensuring the stability of workpiece installation and processing precision. The presence of the mounting holes also allows the installation position of the mechanism to be flexibly adjusted according to actual production needs, adapting to different working scenarios and processing layouts. At the same time, multiple mounting holes increase the firmness and reliability of installation, so that the bottom die can remain stable even when subjected to a large external force. In addition, the design of the mounting holes also facilitates the disassembly and replacement of the mechanism, which can be quickly operated through the mounting holes when the mechanism needs to be maintained or replaced with a bottom die of a different specification, thereby improving work efficiency.

[0018] In summary, the present application at least contains the following beneficial effects:

[0019] 1. The vacuum adsorption effect effectively replaces the traditional mechanical pressing method through the cooperation of the air passage on the bottom die and the installation groove, significantly reducing the scratching and deformation of the workpiece surface, and ensuring the integrity and aesthetics of the workpiece;

[0020] 2. By adjusting the air pressure entering the installation groove, the adsorption force can be flexibly adjusted according to workpieces of different materials and shapes, thereby improving the processing precision and stability of the workpiece;

[0021] 3. The air pressure on-off control is simple and fast, making the workpiece loading and unloading more convenient, and greatly improving the production efficiency and operation convenience. BRIEF DESCRIPTION OF DRAWINGS
