Detailed Description
As shown in the figure, the self-sealing vacuum chuck comprises a chuck body 1, wherein a plurality of vacuum buffer cavities 11 are arranged on the chuck body 1, the shape of each vacuum buffer cavity 11 can be changed as required, an elastic valve connector 2 matched with the vacuum buffer cavity 11 is arranged in each vacuum buffer cavity 11, in the embodiment, each elastic valve connector 2 comprises a valve body 21, a valve core 22 is arranged in each valve body 21, a flow channel 23 is arranged on each valve core 22, the flow channels 23 are used for enabling air flow to pass through, in the embodiment, the flow channels 23 are arranged at the axes of the valve cores 22, the inner diameter of the flow channels 23 is 0.3mm, and thus the vacuum leakage is ensured to be tiny to be negligible. The valve core 22 is provided with the blocking beads 24, a spring 25 is abutted between the valve core 22 and the valve body 21, the transmission blocking beads 24 are moved when the spring 25 is deformed, and the valve port between the valve core 22 and the valve body 21 can be opened and closed through the movement of the blocking beads 24. The sucker body 1 is also provided with a vacuum negative pressure interface 12 communicated with the elastic valve joint 2, and the vacuum negative pressure interface 12 is connected with a vacuum generator.
In this embodiment, in order to achieve a good adsorption effect, the workpiece to be processed is uniformly adsorbed, and a plurality of vacuum buffer chambers 11 are uniformly arranged thereon along the axial direction of the chuck body 1.
In this embodiment, the vacuum buffer chamber 11 is provided with the filter core 3 at the adsorption end of the elastic valve connector 2, and the filter core 3 can adopt an inner hexagonal filter core, which has the function of mainly filtering scrap such as scrap iron particles generated during processing workpieces, preventing the particles from entering the elastic valve connector 2 of the vacuum chuck 1 and even the vacuum generator, and ensuring the normal operation of the vacuum chuck.
In some embodiments, to avoid damage to the table top of the chuck body 1 during processing of the workpiece, a protection plate is mounted on the top of the chuck body 1, and a buffer cavity corresponding to the vacuum buffer cavity 11 is formed on the protection plate. Specifically, the sucker body 1 and the protection plate are sealed by flexible sealant. In this embodiment, in order to ensure good adsorption, the vacuum buffer chamber 11 and the buffer chamber are both cylindrical and have a diameter of 18mm.
The working principle of this embodiment is as follows: when the vacuum generator is started, air in the vacuum buffer cavity 11 is pumped, and at the moment, if a workpiece is not placed at an adsorption port of the vacuum buffer cavity 11, a runner 23 with the diameter of 0.3mm is arranged on the elastic valve joint 2, the runner 23 can allow outside air flow to pass through, and a blocking bead 24 on the valve core 22 is firmly abutted against the valve body 21 through the air flow, so that the valve port is ensured to be in a closed state; if the workpiece only covers a part of the buffer cavity, the external air flow can still pass through the flow channel 23, namely, a vacuum leakage state exists during adsorption, and at the moment, the valve port is automatically closed, so that the principle is the same as that described above; if the workpiece completely covers the vacuum buffer chamber 11, the air in the vacuum buffer chamber 11 is gradually reduced, the air pressure in the valve core 22 is reduced and finally smaller than the restoring force of the spring 25, the spring 25 pushes the valve core 22 to move towards the workpiece, and the blocking beads 24 move synchronously with the valve core 22 and are separated from the valve body 21, so that the valve port is in an open state, and at the moment, the air in the vacuum buffer chamber 11 is pumped out under the action of the vacuum generator, so that the workpiece is forced to be firmly adsorbed on the sucker body 1.
The invention can automatically adsorb the workpiece to be processed without sealing the periphery of the workpiece to be processed by means of the sealing strip, effectively solves the technical problem that the sealing strip is easy to wear or separate from the sealing groove after long-term use, overcomes the defect that the workpiece cannot be firmly adsorbed and effectively processed due to the damage of the sealing strip, and has the advantages of high stability and convenient use.
