In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0028] In the description of the present invention, it should be noted that unless otherwise clearly specified and limited, the terms "installation", "connection", "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations. In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0029] Please refer to Figure 1 and Figure 2, A cutting manipulator shown in a preferred embodiment of the present application includes a manipulator main body 1, a cutting gun head 2, a collision prevention component 3, and a torch box 4. The manipulator main body 1 is provided with a mechanical boom 11 and a mechanical forearm 12 rotatably connected to the mechanical boom 11. The cutting gun head 2 is arranged on the mechanical forearm 12 and is used for processing product workpieces. The collision prevention component 3 is arranged between the mechanical forearm 12 and the cutting gun head 2, and includes a bumper 31 arranged at the end of the mechanical forearm 12 for detecting collision prevention of the cutting gun head 2 and a fixing member 32 arranged between the bumper 31 and the cutting gun head 2. The torch box 4 is arranged at the mechanical boom 11, and the torch box 4 is connected with air pipes and electric wires.

[0030] According to the solution of the embodiment of the present utility model, by arranging the torch box 4 on the mechanical boom 11, the wiring of air pipes and electric wires can be saved, and the wiring can be directly bundled and fixed on the cutting manipulator, without affecting the moving stroke of the cutting manipulator; by arranging the bumper 31 between the mechanical forearm 12 and the cutting gun head 2 to detect collision prevention of the cutting gun head 2, it is avoided that the cutting manipulator continues to move during a collision, causing further collision damage. At the same time, a suitable fixing member 32 is arranged between the bumper 31 and the cutting gun head 2 to make the connection between the two more stable and the force conduction effect better.

[0031] The following will be described in detail with specific embodiments:

[0032] Please refer to Figure 3 , The bumper 31 includes a bumper main body 311 and a connecting ring 312. An end of the bumper main body 311 is provided with a telescopic part 313, and the connecting ring 312 is sleeved on the telescopic part 313 and is connected to the end of the bumper main body 311. The connecting ring 312 is provided with a plurality of connecting grooves 314 along the circumferential direction.

[0033] Please refer to Figure 3 and Figure 4 , The fixing member 32 includes a fixing sleeve 321 and a connecting plate 322. A through hole 323 is axially opened in the middle of the fixing sleeve 321 along the axis of the fixing sleeve 321, and the through hole 323 is used to accommodate the telescopic part 313. The connecting plate 322 is arranged outside the fixing sleeve 321 and is used to connect with the cutting gun head 2. A plurality of connecting keys 324 cooperating with the connecting grooves 314 are arranged on the side wall of the through hole 323 along the circumferential direction, and the ends of the connecting keys 324 extend out of the fixing sleeve 321. By arranging a fixing member 32 adapted to the bumper 31 to connect with the cutting gun head 2, when the cutting gun head 2 collides, the external force generated will be transmitted to the bumper main body 311 through the fixing member 32, the telescopic part 313, and the connecting ring 312. After the bumper main body 311 detects a collision, the movement of the cutting manipulator is stopped at this time to avoid further collision damage between the cutting manipulator and external workpieces or equipment.

[0034] The connecting key 324 and the connecting groove 314 are connected by interference fit. The interference fit between the connecting key 324 and the connecting groove 314 can make the connection between the fixing member 32 and the connecting ring 312 of the anti-collision device 31 more stable.

[0035] Please refer to Figure 1 , a connecting and fitting plate 21 is provided on the cutting gun head 2, and the connecting and fitting plate 21 is connected to the connecting plate 322 by bolts.

[0036] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0037] The above-described embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the utility model patent shall be subject to the appended claims.
