Description

Technical Field

[0001] The utility model relates to the technical field of manipulator processing, in particular to a suction cup type clamp with adjustable suction force. Background Art

[0002] A suction cup clamp is a device that uses the vacuum force generated by a suction cup to fix an object. It is usually used to absorb workpieces with smooth surfaces such as glass, metal or plastic to provide stable clamping. This type of clamp is suitable for various fields such as manufacturing, assembly lines and automation systems.

[0003] The Chinese patent discloses a suction cup manipulator with a suction adjustment function (publication number: CN219466174U). The device is provided with an electric telescopic rod, which can adjust the position of the baffle and the sealing pad, so as to adjust the suction of the device, so as to avoid the inconvenience of workers when using the device due to the inability to adjust the suction. The movement of the top plate can be limited and guided by the cooperation of the guide rod and the guide tube, so as to avoid the top plate from deviating when moving. The installation ring can make the installation assembly of the device more convenient, but the device still has the following defects when in use:

[0004] The above-mentioned device drives the sealing gasket to rise and fall on the inner wall of the machine body through the electric telescopic rod, thereby changing the size of the space connecting the inner wall of the machine body and the through hole, and then changing the strength of the suction of the suction cup below the through hole. However, when the sealing gasket is raised and lowered on the inner wall of the machine body, in order to ensure the sealing of the device, the sealing gasket must be close to the inner wall of the machine body, which increases the friction between the sealing gasket and the inner wall of the machine body. As a result, the sealing gasket may cause wear on the side after multiple rises and falls, that is, a gap is generated between the sealing gasket and the inner wall of the machine body, resulting in poor sealing inside the device and poor adjustment effect of the suction cup. Utility Model Content

[0005] The technical problems to be solved by the utility model are as follows:

[0006] In order to ensure the sealing of the device, the sealing gasket must be close to the inner wall of the body, which increases the friction between the sealing gasket and the inner wall of the body. This may cause wear on the side of the sealing gasket after multiple lifting and lowering, that is, a gap is generated between the sealing gasket and the inner wall of the body, resulting in poor sealing inside the device and poor adjustment effect of the suction cup.

[0032] The bottom of the connecting plate 104 is movably connected with a plurality of baffles 106, and a total of six baffles 106 are provided. The top side of the six baffles 106 is slidably connected to the inner walls of each side of the limiting groove 105, and the outer walls between the six baffles 106 are slidably connected to each other. Figure 4-Figure 5 As shown, the six baffles 106 are closely attached to each other to reduce gaps;

[0033] The outer wall of the connecting plate 104 is rotatably connected to a connecting sleeve 108, the bottom inner wall of the connecting sleeve 108 is located below the bottom of the six baffles 106, and the outer wall of the connecting sleeve 108 is fixedly connected to a worm gear 109, and one side of the outer wall of the worm gear 109 is meshed with the worm 112. Figure 4-Figure 5 As shown, when the worm 112 rotates, it drives the worm wheel 109 to rotate, and when the worm 112 stops rotating, a self-locking is formed between the worm 112 and the worm wheel 109, and the worm wheel 109 cannot drive the worm 112 to rotate;

[0034] A threaded sleeve 110 is fixedly installed on the outer side of the bottom of the connecting sleeve 108. An extrusion groove 111 is opened at the bottom of the connecting sleeve 108 and near the six baffles 106. There are six extrusion grooves 111 in total, and the length directions of the six extrusion grooves 111 do not intersect with the center of the circle of the connecting sleeve 108. The six extrusion grooves 111 are all located on the inner side of the threaded sleeve 110. An extrusion shaft 107 is fixedly connected to one end of the bottom of the six baffles 106.
