[0023] First, it should be noted that the specific structure, features and advantages of the present invention will be specifically described below by way of example, but all descriptions are only for illustration and should not be understood as limiting the present invention in any way. In addition, any single technical feature described or implied in the embodiments mentioned herein can still be combined or deleted between these technical features (or their equivalents) to obtain more other embodiments of the present invention that may not be directly mentioned herein.

[0024] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application may be combined with each other.

[0025] like Figure 1-4 As shown, the present invention provides a wire cutting tool for a live working robot, comprising a wire clamping mechanism 1, a power saw mechanism 2, and a supporting platform 3;

[0026] The clamping mechanism includes a support column 101, which is vertically mounted on the support platform. A hook 102, a first clamp 103, and a second clamp 104 are sequentially mounted on the support column from top to bottom. The hook can hold the line 5, and the first clamp and the second clamp can cooperate with each other to clamp and fix the lead 6.

[0027] The electric saw mechanism includes a rotary motor 201 and a saw blade 202, wherein the saw blade is mounted on the output end of the rotary motor, the rotary motor is located on the support platform, and the rotary motor can be driven to move up and down through a lifting mechanism;

[0028] When the rotary motor is raised to a cutting position through the lifting mechanism, the rotary motor drives the saw blade to cut the lead.

[0029] In this embodiment, a servo 105 is installed on the support column, and the servo is connected to the first clamp via a rotating shaft 8. The servo rotates to drive the first clamp to switch between a vertical state and a horizontal state; and a first groove structure is formed on the side opposite to the first clamp and the second clamp, and a pair of first groove structures can cooperate with each other to clamp and fix the lead.

[0030] In addition, the second clamp is threadedly connected to the first screw 106, the first screw is connected to the first lifting motor 107, the second clamp is connected to the support column through a track, and the first screw is driven to rotate by the first lifting motor, so that the second clamp is lifted up and down along the support column, and a limit block 9 is also installed on the support column. When the second clamp descends and hits the limit block, the first lifting motor stops rotating.

[0031] In addition, it is also conceivable that a second groove structure is formed on the bottom surface of the hook, and the second groove structure can hang the running wire.

[0032] Specifically, in this embodiment, the lifting mechanism includes a support plate 203, a positioning rod 204, and a second lifting motor 205. The positioning rod is vertically fixed on the support platform, and the positioning rod passes through the support plate.

[0033] In addition, it also includes a control module 4, which is connected to the live working robot through a wireless module, and is connected to the steering gear, the first lifting motor, the second lifting motor, and the rotating motor circuit.

[0034] As an example, in the present embodiment, when the present tool is used to cut a wire, the robot first carries the wire cutting tool and sends the wire cutting tool to the wire clamp 8 position; the wire clamping mechanism of the wire cutting tool is inserted into the lead wire and the running wire; when the wire clamping mechanism is in place, the control module instructs the first lifting motor to perform a tightening action; after clamping the running wire and the lead wire, the control module instructs the rotating motor to drive the saw blade to rotate, and controls the second lifting motor to work, and slowly lifts the rotating motor; after the saw blade rotates to the extreme position, the control module instructs the saw blade to stop rotating, and instructs the rotating motor to slowly drop to the initial position; the control module sends a wire cutting operation completion instruction to the robot system through the wireless module, and the robot system operates to control the wire cutting tool to return to the initial position.

[0035] The above embodiments describe the present invention in detail, but the contents are only preferred embodiments of the present invention and cannot be considered to limit the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the present invention.
