[0035] The following details the specific implementation manners of the embodiments of the present utility model with reference to the accompanying drawings. It should be understood that the specific implementation manners described herein are only for explaining and illustrating the embodiments of the present utility model, and are not used to limit the embodiments of the present utility model.

[0036] In an embodiment of the present utility model, as Figure 1 、 Figure 2 and Figure 4As shown in the figure, the portable special vacuum suction cup includes: a vacuum suction cup main body 1, a first ventilation hole 3, and a first ventilation groove 4. One end of the vacuum suction cup main body 1 may be provided with a first interface 2. The first interface 2 can be connected to an external vacuum pumping component, so that vacuum can be pumped. The first ventilation hole 3 can be arranged on the side surface of the vacuum suction cup main body 1 and can be connected to the first interface 2, so that it can be pumped by the first interface 2. The first ventilation groove 4 can be arranged near the top of the side surface of the vacuum suction cup main body 1, and the first ventilation groove 4 can be distributed in a grid shape. The bottom of the first ventilation groove 4 can be connected to the first ventilation hole 3, so that it can be driven by the first ventilation hole 3 to pump air, so that when the main body of the processed part 5 is on the side surface of the vacuum suction cup main body 1, the processed part 5 can be adsorbed. The first ventilation groove 4 can stably adsorb the processed part 5 and will not squeeze the processed part 5, so that the processed part 5 can be stably processed.

[0037] In an embodiment of the present invention, as Figure 1 and Figure 2 shown, the portable special vacuum suction cup may include a first sealing strip 6. The first sealing strip 6 can be clamped on the four peripheral edges of the first ventilation groove 4. When the first ventilation groove 4 sucks air, external air will not be sucked into the first ventilation hole 3 from the four peripheral edges of the first ventilation groove 4, so that a vacuum can be formed between the processed part 5 and the first ventilation groove 4, and further the processed part 5 can be closely attached to the vacuum suction cup main body 1.

[0038] In an embodiment of the present invention, as Figure 1 shown, the portable special vacuum suction cup may include a plurality of first positioning pins 7. The first positioning pins 7 can be arranged around the first ventilation groove 4, so that when the first ventilation groove 4 adsorbs the processed part 5, the displacement of the processed part 5 can be restricted, so that the processed part 5 can be stably fixed on the vacuum suction cup main body 1.

[0039] In an embodiment of the present invention, as Figure 1 and Figure 3As shown, the portable special vacuum suction cup may include: a second connection port 8, a second ventilation hole 9, and a second ventilation groove 10. The second connection port 8 may be provided on the side surface of the vacuum suction cup main body 1 opposite to the first ventilation groove 4. The second ventilation hole 9 may be provided at the top of the vacuum suction cup main body 1 and may be connected to the second connection port 8, so that it can be evacuated by the second connection port 8. The second ventilation groove 10 may be provided on one side of the top of the vacuum suction cup main body 1 close to the second connection port 8. The second ventilation groove 10 may be distributed in a grid pattern. The bottom of the second ventilation groove 10 may be connected to the second ventilation hole 9, so that it can be driven to draw air by the second ventilation hole 9. When the main body of the processed part 5 is on the top of the vacuum suction cup main body 1, the processed part 5 can be adsorbed.

[0040] In an embodiment of the present invention, as Figure 3 shown, the portable special vacuum suction cup may include a second sealing strip 11. The second sealing strip 11 may be clamped on the four peripheral edges of the second ventilation groove 10. When the second ventilation groove 10 sucks air, external air will not be sucked into the second ventilation hole 9 from the four peripheral edges of the second ventilation groove 10, so that a vacuum can be formed between the processed part 5 and the second ventilation groove 10, and further the processed part 5 can be closely attached to the vacuum suction cup main body 1.

[0041] In an embodiment of the present invention, as Figure 1 shown, the portable special vacuum suction cup includes a plurality of second positioning pins 12. The second positioning pins 12 may be provided on the periphery of the second ventilation groove 10. When the second ventilation groove 10 adsorbs the processed part 5, the displacement of the processed part 5 can be restricted, so that the processed part 5 can be stably fixed on the vacuum suction cup main body 1.

[0042] In an embodiment of the present invention, as Figure 1 shown, pressing plate grooves 13 may be provided on both sides of the bottom of the vacuum suction cup main body 1. The pressing plate grooves 13 may facilitate the fixing of the vacuum suction cup main body 1 by an external pressing plate member through them.

[0043] In an embodiment of the present invention, as Figure 1 shown, a plurality of first threaded holes 14 extending along the length direction and width direction of the first ventilation groove 4 may be provided on the side surface of the vacuum suction cup main body 1. The first positioning pin 7 may be screwed into the first threaded hole 14. Therefore, when fixing the processed part 5, the position of the first positioning pin 7 can be reasonably adjusted according to the size of the processed part 5, so that the first positioning pin 7 can better restrict the displacement of the processed part 5.

[0044] In an embodiment of the present invention, as Figure 1As shown in the figure, multiple groups of second threaded holes 15 extending along the length direction and width direction of the second ventilation groove 10 may be provided at the top of the vacuum suction cup body 1. The second positioning pin 12 can be screwed into the second threaded hole 15. When fixing the machined part 5, the position of the second positioning pin 12 can be reasonably adjusted according to the size of the machined part 5, so that the second positioning pin 12 can better limit the displacement of the machined part 5.

[0045] Through the above technical solution, a portable special vacuum suction cup provided by the present utility model is provided with a vacuum suction cup body, and a first interface may be provided at one end of the vacuum suction cup body. The first ventilation hole may be provided on the side surface of the vacuum suction cup body and may be connected to the first interface, so that it can be evacuated by the first interface. The first ventilation groove may be provided near the top of the side surface of the vacuum suction cup body. The first ventilation groove may be distributed in a grid shape, and the bottom of the first ventilation groove may be connected to the first ventilation hole, so that it can be driven to pump air by the first ventilation hole. Thus, when the main body of the machined part is on the side surface of the vacuum suction cup body, the portable special vacuum suction cup can adsorb the machined part, quickly clamp the machined part, and keep the machined part stable during the machining process and ensure that the machined part will not deform.

[0046] It should also be noted that the term "including", "comprising" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, commodity or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or further includes elements inherent to such process, method, commodity or device. Without further limitation, an element defined by the statement "including one..." does not exclude the existence of another identical element in the process, method, commodity or device including the element.

[0047] The above are only the embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the scope of the claims of the present application.
