Description

Technical Field

[0001] The utility model relates to the technical field of automobile component grippers, in particular to an automobile component gripper. Background Art

[0002] As the foundation of the automobile industry, automobile parts are necessary factors to support the sustainable and healthy development of the automobile industry. In particular, the independent development and innovation that is being carried out vigorously in the current automobile industry requires a strong parts system to support it. Automobile parts include engine parts, transmission parts, brake parts, steering parts and body parts. When processing automobile parts, especially on the production line, it is necessary to use grippers and other structures to grab and fix the processed parts and quickly transfer them; however, automobile parts vary in size and shape, especially some stamping parts, which have more complex shapes, and the conventional grippers use structures such as splints or clamps, which are not convenient for clamping and fixing parts with complex shapes.

[0003] And in the application document with publication number CN217195384U, a special gripper for automobile parts production line is mentioned. The gripper connects the gripper structure with an external mobile device or a robotic arm during operation. When the gripper is needed to grab the parts of regular shape, the motor of the second drive component is started according to actual needs, and the transmission shaft 202 is rotated through the second drive component, and the rotating shaft 301 is used to drive the splint 3 to rotate through the transmission component, so that the splint 3 is at a certain angle and located on both sides of the parts, and then the motor of the first drive component is started, and the two screws 201 are rotated at the same time through the first drive component, so that the two moving rods 2 simultaneously drive the splint 3 to move inward, clamp and fix the parts through the splint 3, and then transfer the grabbed parts through the external mobile device or robotic arm. When the shape of the parts is complex and it is not convenient to clamp and fix them by the clamping plate 3, the corresponding shape of the plug block 304 is installed on the fixing block 302 through the threaded hole and the threaded shaft 305, and the position and angle of the plug block 304 are adjusted by the first drive component, the second drive component and the transmission component so that the plug block 304 can be inserted into the slot at the corresponding position on the parts, so that the parts can be positioned by the two plug blocks 304, so that the parts can be grasped and transferred by the gripper. However, there are still some defects that need to be optimized. The specific defects are as follows: the gripper is too cumbersome to install and disassemble the plug block, which reduces the grasping efficiency.

[0004] Therefore, it is particularly important to design a gripper for automotive parts to change the above-mentioned technical defects and improve overall practicality. Utility Model Content
