Description

TECHNICAL FIELD

[0001] The utility model relates to the field of mechanical gripper, specifically relates to a terminal gripper grabbing quick change device. BACKGROUND

[0002] At present, when the product model, specification or production process on the production line changes, different types and sizes of grippers may need to be replaced to adapt to new production tasks. At present, when replacing the terminal gripper, tools are usually used to replace the gripper, and appropriate tools such as wrenches and screwdrivers need to be found first, and then disassembly and installation operations are performed. These steps are relatively cumbersome and time-consuming, especially in the case of frequent replacement of grippers, which will seriously affect production efficiency. Moreover, when using tools to install the gripper, it may not be possible to ensure the fastening degree and stability of the connection part. If the screw tightening degree is not enough or the tightening sequence is incorrect, it may cause the gripper to loosen or fall off during work, affecting the normal production, and frequent use of tools may cause damage to the connection part and the structure of the gripper, such as thread wear and bayonet deformation, which will reduce the reliability and service life of the gripper and increase maintenance and replacement costs. At the same time, during the process of disassembling and installing the gripper using tools, the operator's technique, force and operation accuracy have a great influence on the installation accuracy of the gripper.

When the locking plate 16 of the end gripper 1 is inserted into the cavity 3 in the gripper head seat 2... Since the cavity 3 has a stepped structure, the top of the locking plate 16 rests against the plane in the cavity, limiting the locking plate 16. This ensures that the locking hole 17 on the locking plate 16 and the locking head 6 are on the same horizontal plane. The elastic force of the compression spring 14 will push the lifting frame 9 downward. The lifting frame 9 will push the left rotating plate 7 and the right rotating plate 8, causing the left rotating plate 7 and the right rotating plate 8 to rotate on the same horizontal plane. The left rotating plate 7 and the right rotating plate 8 will horizontally push the locking head 6 to move horizontally in the insert plate 5. When the two locking heads 6 move, they will insert into the locking hole 17 of the locking plate 16, completing the installation of the end gripper 1 and the gripper head seat 2.
