Description

Technical Field

[0001] This utility model belongs to the field of clamping technology, specifically relating to a clamping fixture for handling profiles. Background Technology

[0002] Due to their long axial length, long strip-shaped materials require multiple clamps to grip them simultaneously. Existing publication CN118288093A discloses a clamping device for profile processing equipment, including a clamping frame. Double-bar sliding table cylinders are located on both sides of the frame's bottom. Pneumatic gripper cylinders and chuck bodies are connected via connectors. Multiple positioning pins and chuck H-links connect the chuck bodies and the gripper fingers. This experimental novel clamping device for profile processing equipment uses cylinders to control lifting and a servo motor to control the support height. The mechanical gripper moves along the sliding bar to achieve stable gripping of larger profiles. The air intake and exhaust of the pneumatic gripper cylinders control the tightness of the chuck fingers. However, the frame bottom has multiple chuck bodies, and their vertical height cannot be adjusted. Because the materials to be gripped have long axial lengths, the chuck bodies cannot maintain a uniform horizontal height, resulting in inability to grip materials simultaneously and poor gripping performance. Therefore, a dedicated clamping device for profile handling needs to be designed. Summary of the Invention

During the rising process, the clamping component 5... The photoelectric scanning sheet metal 53 triggers the second photoelectric sensor 42, which in turn sends a working command to the drive cylinder 54. When the drive cylinder 54 works, it controls the claw arms 510 to move closer to each other, thereby clamping the material. When the main body connecting seat 51 rises to the vicinity of the first limit block 47, the first photoelectric scanning sheet metal 52 triggers the first photoelectric sensor 41, which in turn sends a working command to the robot to stop descending. At this time, each of the clamping components 5 has clamped the material. Then, the robot controls the main frame 1 to rise, thus transferring the material.
