A vacuum chuck is a machining table with vacuum adsorption force, which can adsorb plate-shaped or irregular workpieces on its surface to fix the workpiece. Traditional vacuum chucks have a simple structure with air channels in the chuck. The structure is relatively fixed and cannot be modularly disassembled. Therefore, during the machining process, the debris generated may enter the air channels and block them, which is difficult to clean and affects the machining efficiency. Utility Model Content

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0020] Example 1:

[0021] A modular vacuum suction cup, such as Figure 1 , Figure 2 and Figure 4 As shown, the device includes a base 1 and several sealing blocks 2. The base 1 has several mounting grooves 11, each a rectangular recess. The mounting grooves 11 are spaced apart. The sealing blocks 2 are placed in the mounting grooves 11 and interlock with them. Through holes are provided between adjacent mounting grooves 11. Each sealing block 2 includes a sealing part 21 and a support part 22. The sealing part 21 is rectangular and mates with the mounting grooves 11. The support part 22 is a rectangular frame structure, located below the sealing part 21 and welded to it. Each side of the support part 22 is a plate-like structure surrounding the bottom edge of the sealing part 21. The support part 22 spaces the sealing part 21 from the bottom of the mounting grooves 11. Clearance holes 2 are provided around the support part 22. 21. The positioning holes 221 on each side of the support 22 are matched with the through holes, so that the airflow can pass smoothly through the bottom of the sealing part 21. An air passage assembly is provided on the sealing part 21. Two air nozzles 3 are provided on one side of the base 1. Both air nozzles 3 are connected to the mounting groove 11. The air nozzles 3 are used to connect to an external air pump. A cover 4 is provided on the sealing block 2. The cover 4 is the same size as the sealing block 2. Multiple pins 41 are provided on the cover 4. The pins 41 are inserted into the air passage assembly of the sealing block 2. After the workpiece is placed on the surface of the vacuum suction cup, part of the sealing block surface does not come into contact with the workpiece. Therefore, it is necessary to seal it with the cover 4 to keep it sealed. After the cover 4 is inserted into the sealing block 2, it can seal the sealing block 2, thereby improving the adsorption effect of the remaining sealing block 2 surfaces.

The main airway 211 is located at the central axis of the sealing section 21 and runs through the sealing section 21. The four auxiliary airways 212 are arranged around the main airway 211 and are parallel to it. The auxiliary airways 212 also run vertically through the sealing section 21. A groove is provided at the bottom of the sealing section 21 at the location of the main airway 211. The groove is a conical recess. The main air duct 211 is located at the geometric center of the groove, which guides and gathers the airflow. Four auxiliary air ducts 212 are located at the edges of the groove. The mounting groove 11 of the base 1 has slots 111 around its bottom. The bottom of the support portion 22 of the sealing block 2 is inserted into the slots 111 to further improve the sealing performance of the sealing block 2.
