Description

Technical Field

[0001] This utility model relates to the field of robotic arm technology, specifically to a robotic arm gripper structure capable of precise grasping. Background Technology

[0002] As the core execution component of industrial robots and automation systems, the development of robotic grippers has always revolved around the needs of "precise grasping, flexible adaptation, and efficient operation." They are a key technology carrier for realizing "machine replacement of humans" in the fields of industrial automation, intelligent manufacturing, and special operations. In the product transfer process, products need to be transferred, so robotic gripper structures have become an indispensable key auxiliary tool in the product transfer process.

[0003] Existing robotic gripper structures are relatively complex and poorly designed, and their applications are limited. Figure 1 When grasping U-shaped products, their special shape makes grasping inconvenient and requires a lot of time to fix them, which affects grasping efficiency and reduces product transfer efficiency.

It has the advantages of simple structure, reasonable design, easy positioning and fixing of U-shaped products, and improved grasping efficiency, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a robotic gripper structure capable of precise grasping, comprising: a drive mechanism for fixing the gripper, the drive mechanism including a base, and finger cylinders provided at both ends of the base;

[0006] A gripping mechanism for gripping products, wherein two gripping mechanisms are provided and placed on a drive mechanism, and each gripping mechanism includes a gripping component, each gripping component includes two symmetrically arranged grippers, the ends of the two grippers near the drive mechanism are provided with grooves, and the opposing sides of the two grippers are provided with mounting holes.

[0007] Preferably, the base has several through holes, and each finger cylinder output end is provided with a slide, and two sliders slide inside each slide.

[0008] Preferably, both sliders sliding within each of the carriages are connected to the gripping assembly.

[0009] Preferably, an aluminum gripper is provided at the end of the gripper away from the drive mechanism, and a positioning plate is provided on the aluminum gripper, with two positioning surfaces symmetrically arranged on the inner side of the positioning plate.

[0010] Preferably, a protective block is provided on the side of the gripper away from the groove, and the thickness of the protective block is greater than the thickness of the positioning plate.

[0011] Preferably, the aluminum claw is provided with a positioning block, which is placed between the positioning plate and the protective block.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model provides a robotic gripper structure for precise grasping. The robotic gripper includes a drive mechanism and a gripping mechanism. The overall structure is simple and reasonably designed. Through the aluminum gripper set on the gripper, the positioning plate set on the aluminum gripper is embedded into the groove opened on the product and positioned by the positioning block. The two finger cylinders work synchronously to drive the two gripping mechanisms to clamp and open synchronously, which facilitates the positioning and grasping of U-shaped products and improves the gripping efficiency.
