[0001] The utility model relates to the field of mechanical automation, in particular to an adjustable clamping claw grabbing device. Background Art

[0002] With the development of industries such as rolling bearings and electric motors, automated production lines have begun to appear in mechanical manufacturing. Products produced using automated production lines have high output, advanced product design and technology, and are stable and reliable. They remain basically unchanged for a long time. The extensive use of automated production lines in production can improve labor productivity, stabilize and improve product quality, reduce production costs, and have significant economic benefits.

[0003] Among them, the mechanical gripper is an automated device with workpiece capture and movement functions used in automated production, such as the patent application with publication number CN 219075726 U in the prior art, which includes an adjustable mechanical gripper including a mounting seat, a plurality of clamping mechanisms slidably connected to the mounting seat and lockable in a set position; and also includes an adjustment device for adjusting the distance between any two adjacent clamping mechanisms; the adjustment device is arranged on the mounting seat and is located between any two adjacent clamping mechanisms. Among them, the set position is the position where the clamping mechanism abuts the adjustment device. In the above technical scheme, by adopting the method of arranging an adjustment device between two adjacent clamping mechanisms, the purpose of calibrating the distance between adjacent clamping mechanisms is achieved, thereby improving the situation in which the appearance of the product is damaged when the clamping mechanism takes and puts the product due to the mismatch between the product spacing and the clamping mechanism spacing.

[0004] However, when the device is in use, when the distance between the jaws is adjusted too large, due to the limited range of movement of the jaws, some of the jaws will be squeezed together and cannot be adjusted in position, resulting in the need to reduce the number of workpieces grasped. This not only reduces the adaptability of the device, but also reduces work efficiency.

[0005] Therefore, it is necessary to provide an adjustable clamping claw grasping device to solve the above technical problems. Utility Model Content
