Description

Technical Field

[0001] This utility model relates to the field of mechanical automation technology, specifically to a feeding mechanical claw structure with an elliptical clamping part. Background Technology

[0002] In the field of automated material handling, the gripping accuracy and adaptability of robotic grippers directly affect production efficiency. In existing technologies, the gripping parts of traditional robotic grippers are mostly conventional shapes such as circles or rectangles, which are difficult to adapt to irregularly shaped workpieces (such as elliptical or irregularly curved workpieces), and are prone to problems such as unstable gripping and workpiece slippage.

[0003] Meanwhile, some robotic grippers use rigid clamping and lack anti-slip design, resulting in insufficient friction when gripping smooth workpieces, leading to positioning deviations; moreover, the connection between the gripper and the robotic arm is mostly a fixed structure, which cannot flexibly adjust the installation position, and requires readjustment when changing workpiece models, increasing production changeover costs.

[0004] Furthermore, single-degree-of-freedom robotic arms struggle to meet the three-dimensional spatial motion requirements of complex material handling scenarios, thus limiting the integration efficiency of automated production lines. Therefore, there is an urgent need for a highly adaptable, stable, and flexible material handling robotic gripper structure. Summary of the Invention

[0005] The purpose of this invention is to provide a feeding machine claw structure with an elliptical clamping part to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a loading mechanical claw structure with an elliptical clamping part, comprising: A multi-axis robotic arm, wherein the multi-axis robotic arm has a free end; A gripper, mounted on the free end of the multi-axis robotic arm, the gripper comprising: A vertical cylinder is fixed to the free end of the multi-axis robotic arm; A pneumatic gripper is connected to the end of the piston rod of the vertical cylinder; An elliptical clamping part is provided at the end of the pneumatic gripper to adapt to the shape of a specific workpiece.

[0007] Preferably, the inner surface of the elliptical clamping part is provided with an anti-slip rubber pad to increase the friction on the workpiece.

[0008] Preferably, the multi-axis robotic arm includes at least three movable joints for realizing the movement of the gripper in three-dimensional space.

[0009] Preferably, the vertical cylinder is connected to the multi-axis robotic arm via a mounting plate, which has multiple adjustment holes for adjusting the mounting position of the gripper.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting an elliptical clamping part, this utility model can accurately adapt to the shape of specific irregular workpieces, solving the problem of unstable gripping of irregular workpieces by traditional grippers; the anti-slip rubber pad on the inner surface of the elliptical clamping part can increase the friction with the workpiece, preventing the workpiece from slipping or deviating in positioning during the gripping process; the multi-axis robotic arm has at least three movable joints, which can realize the flexible movement of the gripper in three-dimensional space, meeting the needs of complex loading scenarios; the vertical cylinder is connected to the multi-axis robotic arm through a mounting plate with adjustment holes, which facilitates flexible adjustment of the gripper installation position, and the pneumatic gripper is detachable and replaceable to adapt to different types of workpieces, reducing production changeover costs and improving the efficiency and stability of automated loading.
