Vacuum suction cups are one of the actuators of vacuum equipment. There are various types of vacuum suction cups. Suction cups made of rubber can be operated at high temperatures. Suction cups made of silicone rubber are very suitable for grasping products with rough surfaces. Suction cups made of polyurethane are very durable. In addition, in actual production, if the suction cup is required to be oil-resistant, you can consider using materials such as polyurethane, nitrile rubber or vinyl-containing polymers to make the suction cup.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technical personnel in this field without creative work are within the scope of protection of the utility model.
[0021] See also Figure 1-Figure 6The utility model provides a technical solution: a special vacuum suction cup for shell, comprising a shell body 1, the side surfaces of the shell body 1 are movably connected with adjustment plates 2 through hinges, one side of each adjustment plate 2 is fixedly connected with a pressing frame 3, a movable rod 4 is movably sleeved in the hole on each pressing frame 3, the outer wall of the movable rod 4 is movably sleeved with a deformation cylinder 5, a metal ring on the deformation cylinder 5 is sleeved with a bracket 6, one side of the bracket 6 is fixedly connected with an adsorption frame 7, the bottom of the shell body 1 and the adsorption frame 7 are respectively fixedly connected with suction cup bodies 8, the adjustment plates 2 are distributed in an annular array, and the suction cup bodies 8 at the bottom of the shell body 1 are distributed in an annular array. When the suction cup bodies 8 are adsorbed on the shell, the rotating knob 10 is manually turned to deform the two sides of the pressing frame 3, tilt toward the middle and squeeze the two ends of the deformation cylinder 5. Since the middle part of the deformation cylinder 5 is made of rubber material, its two ends It is made of metal, so when the two ends of the deformation tube 5 are squeezed, the rubber part on the deformation tube 5 is deformed, which can increase the friction force of the deformation tube 5 on the movable rod 4, and then the adsorption frame 7 cannot be rotated through the deformation tube 5. By installing the deformation tube 5, it itself has the characteristics of elastic deformation, and the two ends of the deformation tube 5 are metal rings, and the middle part is made of rubber material. Multiple adjustment plates 2 and adsorption frames 7 are installed on the side surface of the shell body 1, which can be adsorbed on multiple surfaces on irregular workpieces, and by rotating the rotating knob 10, the two sides of the pressing frame 3 are deformed, tilted to the middle and the two ends of the deformation tube 5 are squeezed, which can cause the rubber part on the deformation tube 5 to deform, which can increase the friction force of the deformation tube 5 on the movable rod 4, and then the adsorption frame 7 is fixed, avoiding the vacuum suction cup from being adsorbed only on the relatively flat part of the workpiece, which is beneficial to improve the clamping effect of the device.
[0022] In this embodiment, Figure 1 , Figure 2 and Figure 4 As shown, a latch 9 is sleeved in the hole on the movable rod 4, a rotating knob 10 is fixedly sleeved at one end of the movable rod 4, and the rotating knob 10 is movably connected to the other side of the pressing frame 3. The top of the shell body 1 is fixedly connected to an air suction pipe 11, and the top of the shell body 1 is fixedly connected to a fixing buckle 12. The side surfaces of the shell body 1 are respectively fixedly connected to branch pipes 13, and each branch pipe 13 is fixedly connected to the side surface of the air suction pipe 11. The branch pipes 13 are distributed in an annular array, and the side surfaces of the shell body 1 are respectively fixedly connected to protective sleeves 14, which are distributed in an annular array. Before use, the device is first fixed by the fixing buckle 12, and the adsorption rack 7 is assembled and disassembled according to the irregular shell. Then, by placing each adsorption rack 7 on the irregular shell, the air suction pipe 11 will be connected to the vacuum pump to evacuate air, so that the gas between each suction cup body 8 and the shell is fully extracted, and then the sealing ring 15 on the suction cup body 8 can prevent air from entering from the gap between the suction cup body 8 and the shell to affect the adsorption effect of the suction cup body 8.
[0023] In this embodiment, Figure 5 and Figure 6 As shown, the branch pipe 13 is sleeved inside the protective sleeve 14, and a sealing ring 15 is fixedly sleeved in the annular groove on each suction cup body 8. The side surfaces of the outer shell body 1 are respectively provided with movable grooves 16, and the movable grooves 16 are distributed in an annular array. When adding or adjusting the adsorption rack 7, since the protective sleeve 14 itself has a softer material with deformation ability, the connection between the branch pipe 13 and the outer shell body 1 is protected by the protective sleeve 14 to prevent the connection between the branch pipe 13 and the outer shell body 1 from being worn during long-term use. The protective sleeve 14 itself has deformation ability and is made of a softer material. During long-term use, the connection between the branch pipe 13 and the outer shell body 1 can be protected by the protective sleeve 14 to prevent the connection between the branch pipe 13 and the outer shell body 1 from being worn during long-term use, which is beneficial to improving the service life of the device.
[0024] The use method and advantages of the utility model: The special vacuum suction cup for the shell, when in use, the working process is as follows:
[0025] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, before use, the device is fixed by the fixing buckle 12, and the adsorption frame 7 is assembled and disassembled according to the irregular shell, and then each adsorption frame 7 is placed on the irregular shell, and the suction pipe 11 is connected to the vacuum pump to evacuate the air so that the gas between each suction cup body 8 and the shell is completely extracted, and then the sealing ring 15 on the suction cup body 8 can prevent the air from entering from the gap between the suction cup body 8 and the shell to affect the adsorption effect of the suction cup body 8. After the suction cup body 8 is adsorbed on the shell, the rotating knob 10 is manually turned to deform the two sides of the pressing frame 3, tilting toward the middle and aligning the shape. The two ends of the deformation tube 5 are squeezed. Since the middle part of the deformation tube 5 is made of rubber material and its two ends are made of metal, when the two ends of the deformation tube 5 are squeezed, the rubber part on the deformation tube 5 is deformed, which can increase the friction of the deformation tube 5 on the movable rod 4, and then make the adsorption frame 7 unable to rotate through the deformation tube 5. When adding or adjusting the adsorption frame 7, since the protective sleeve 14 itself has a softer material with deformation ability, the connection between the branch pipe 13 and the outer shell body 1 is protected by the protective sleeve 14 to prevent the connection between the branch pipe 13 and the outer shell body 1 from being worn during long-term use.
[0026] The above shows and describes the basic principle, main features and advantages of the utility model. Technical staff in this industry should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model will have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
