[0035] Specifically, a plurality of placement grooves 111 are arranged in a straight line, and the arrangement direction is parallel to the sliding direction of the limiting plate 12. The limiting plate 12 is provided with avoidance holes corresponding to the placement grooves 111, and the inner wall of the avoidance holes is provided with a limit block 121 for limiting the chuck 22. The limit plate 12 includes a limit position and an open position on the sliding track. When the limit plate 12 is located at the limit position, the limit block 121 is opposite to the placement groove 111 so as to limit the chuck 22 in the placement groove 111. When the limit plate 12 is located at the open position, the limit block 121 is misaligned with the placement groove 111 so that the gripping device can take away the chuck 22 in the placement groove 111.

The first positioning plate is connected to the side of the limiting plate 12, and the second positioning plate is opposite to the bottom surface of the main plate 11. The positioning strip can ensure the stability of the sliding connection between the limiting plate 12 and the main plate 11.

[0040] In this embodiment, the switching device of the clamp 22 further includes a connecting plate 18 , an extending plate 13 , and a first driving member 16 .

When the connection column 214 is plugged with the connection hole, under the pull of the tension spring 213, the two clamping shafts 212 are limitedly contacted on the side of the block 222 away from the end of the connection hole, thereby limiting the chuck 22 from being disengaged from the connection groove 211. The connector 21 is lowered and applied with force to squeeze the chuck 22 to form a clamping assembly.

[0047] An extension plate 223 is provided around one end of the main rod 221 away from the clamping block 222 to be restricted by the limiting plate 12. When the connector 21 and the clamp 22 need to be disassembled, the connector 21 is moved upward and away from the main plate 11, and the clamp 22 can be disengaged from the connecting groove 211 due to the limiting block 121 of the limiting plate 12 pressing the extension plate 223, thereby realizing the disassembly of the connector 21 and the clamp 22.

In this way, different types of chucks 22 can be placed by setting different fixture frames 123.

[0049] The working principle of the utility model is as follows: when the chuck 22 needs to be replaced, the gripping device moves to the top of the main plate 11, and then descends to insert the chuck 22 into the placement groove 111, the first driving member 16 drives the limit plate 12 to move to the limit position, the limit block 121 presses the expansion plate 223, and the connecting head 21 rises and applies force in the direction away from the main plate 11, so that the chuck 22 can be disengaged from the connecting groove 211.

[0050] Then, the gripping device moves to the top of the target chuck 22 that needs to be replaced, the connecting head 21 descends and applies force to squeeze the chuck 22 to form a snap-fit ​​assembly, and then the first driving member 16 drives the limiting plate 12 to move to the open position, so that the newly replaced chuck 22 can be removed.

[0051] This completes the process of automatically disassembling and replacing the chuck of the automatic claw changing mechanism of the mechanical gripper for a special-shaped insertion machine of the preferred embodiment.

[0052] The automatic claw changing mechanism of the mechanical gripper for the special-shaped plug-in machine of this preferred embodiment can place multiple different types of chucks by setting a main body plate, and then restrict or loosen the chuck in the placement groove through the limit plate, so as to realize the disassembly and assembly of the connecting head and the chuck in the placement groove, and realize the automatic replacement of the chuck, thereby improving work efficiency and reducing cost.

[0053] In summary, although the present invention has been disclosed as above in terms of preferred embodiments, the above preferred embodiments are not intended to limit the present invention.
