As shown in fig. 1-2, an embodiment of a tool changer with a tool fall-preventing device is provided, which includes a tool changer body 1 having an inlet 101, where the tool changer body 1 is provided with a fall-preventing device 2 at the inlet 101, and the fall-preventing device 2 includes a blocking portion 201 slidably connected to the tool changer body 1 and a driving mechanism for driving the blocking portion 201 to slide in a vertical direction; the driving mechanism pushes the blocking part 201 to extend out of the tool changing frame body 1 to the tool feeding opening 101 or pushes the blocking part 201 to retract into the tool changing frame. The blocking portion 201 may be a pin.

Specifically, the driving mechanism includes a movable block 202 connected to the stopper 201, a driving assembly for driving the movable block 202 to move downward, and a first elastic member 203 for urging the movable block 202 to return. The driving assembly pushes the movable block 202 to move downwards, and the movable block 202 moves downwards with the blocking portion 201. The driving assembly comprises a driving block 204 provided with a first inclined surface 2041 and a second elastic piece 205 for pushing the driving block 204 to move in the horizontal direction; the first inclined surface 2041 is disposed on the bottom surface of the driving block 204, and the top surface of the movable block 202 is disposed with a second inclined surface 2021 attached to the first inclined surface 2041. When an external force acts on the driving block 204 and causes the driving block 204 to move in the horizontal direction and compress the second elastic element 205, due to the joint action of the first inclined surface 2041 and the second inclined surface 2021, the movable block 202 moves downward, so as to drive the blocking portion 201 to move downward, and cause the blocking portion 201 to retract into the tool changer body 1. When the external force is removed, the compressed second elastic member 205 pushes the driving block 204 to reset, and the first elastic member 203 also pushes the movable block 202 to reset, so that the blocking portion 201 is reset. The first elastic member 203 and the second elastic member 205 are both springs.

Wherein, the driving block 204 extends out of the tool changing frame body 1. The driving block 204 is used for abutting against a tool changing trolley, when the tool changing trolley is spliced with the tool changing frame body 1, the tool changing trolley pushes the driving block 204 to move horizontally, the blocking part 201 moves downwards, and after the tool changing trolley is separated from the tool changing trolley, the blocking part 201 resets. The driving mechanism does not need to be additionally started, any operation action does not need to be added by an operator, and the use is more convenient.

Specifically, the anti-falling device 2 includes a housing 206 provided with a notch 2061, the movable block 202, the first elastic member 203 and the driving assembly are all installed in the housing 206, the blocking portion 201 is slidably connected with the housing 206, and the driving block 204 extends out of the housing 206 through the notch 2061. The anti-falling device 2 is provided with the shell to form an integral structure, so that the anti-falling device 2 is more convenient to mount and dismount and is convenient to maintain and replace.
