The first feature being "below", "under" and "beneath" the second feature includes the first feature being directly below and obliquely below the second feature, or merely indicating that the first feature has a lower horizontal height than the second feature.

[0041] The technical solution of the present invention will be further described below with reference to the drawings and through specific embodiments.

[0042] As Figures 1 - 6 shown, this embodiment provides a welding torch housing, which includes a housing body 100 and a connecting device 200. The housing body 100 includes a first housing 110 and a second housing 120 that are rotatably connected; the connecting device 200 includes a limiting component and a first housing 210 and a second housing 220 that are rotatably connected. The limiting component includes a limiting rod 241, and the limiting rod 241 is slidably disposed in either the first housing 210 or the second housing 220; among the first housing 110 and the second housing 120, one is connected to the first housing 210 or the second housing 220, and the other is provided with a limiting groove, and at least part of the limiting rod 241 can slide into the limiting groove to lock the first housing 110 and the second housing 120.

[0043] By providing a limiting component on the connecting device 200, it is used to associate the first housing 210 and the second housing 220 of the connecting device 200 with the first outer housing 110 and the second outer housing 120 of the outer housing body 100, so that the outer housing body 100 can be opened and closed only through the connecting device 200 without additional connecting parts and tools, realizing the quick disassembly and assembly of the outer housing of the handheld laser welding gun. Specifically, one of the first outer housing 110 and the second outer housing 120 is connected to the first housing 210 or the second housing 220, and a limiting groove is provided on the other. The limiting rod 241 of the limiting component is slidably arranged on either the first housing 210 or the second housing 220. By at least partially placing the limiting rod 241 in the limiting groove, the locking of the first outer housing 110 and the second outer housing 120 is realized.

[0044] Specifically, to realize the connection between the second housing 220 and the second outer housing 120, a connecting part 223 is provided on the second housing 220, and the second outer housing 120 is connected to the connecting part 223. Optionally, the second outer housing 120 and the connecting part 223 are connected by bolts, which is convenient for disassembly. To realize the installation of the limiting rod 241, a limiting installation hole 224 is provided on the second housing 220, and the limiting rod 241 is slidably arranged in the limiting installation hole 224.

[0045] Furthermore, to facilitate the sliding of the limiting rod 241, the limiting component is further provided with an operating part 242 connected to the limiting rod 241. An operating hole 225 is provided on the second housing 220, and the operating hole 225 communicates with the limiting installation hole 224. The operating part 242 is slidably arranged in the operating hole 225 and at least partially protrudes from one end of the operating hole 225 away from the limiting installation hole 224. The operator can move the position of the limiting rod 241 by sliding the operating part 242, thereby realizing the limitation between the outer housing body 100 and the connecting device 200. Exemplarily, the part of the operating part 242 protruding from one end of the operating hole 225 is larger than the cross-section of the operating hole 225 to have a larger operating area, which is convenient for the operator to operate.

[0046] To realize the connection between the limiting rod 241 and the operating part 242, an external thread connecting part 2411 is provided on the limiting rod 241, and an internal thread connecting part 2421 is provided on the operating part 242. When assembling the limiting component, the limiting rod 241 passes through the limiting installation hole 224, the operating part 242 passes through the operating hole 225, and the external thread connecting part 2411 is threadedly connected to the internal thread connecting part 2421.

[0047] Further, the portion of the limiting rod 241 that can be placed in the limiting groove is set as the limiting portion 2412. In this embodiment, a mating portion 2413 is provided at one end of the external thread connecting portion 2411 close to the limiting portion 2412. With this arrangement, the external thread connecting portion 2411 and the internal thread connecting portion 2421 can be fully screwed, so that the external thread connecting portion 2411 and the internal thread connecting portion 2421 are disengaged from the threaded connection, and the operating portion 242 is located at the mating portion 2413 between the limiting portion 2412 and the external thread connecting portion 2411. Since the outer diameter of the mating portion 2413 is smaller than the inner diameter of the external thread connecting portion 2411, when the limiting rod 241 is driven to move by the operating portion 242, the internal thread connecting portion 2421 cooperates with the mating portion 2413, avoiding axial force on the threads between the external thread connecting portion 2411 and the internal thread connecting portion 2421, and protecting the reliability of the threaded connection between the external thread connecting portion 2411 and the internal thread connecting portion 2421.

[0048] Optionally, one end of the mating portion 2413 away from the external thread connecting portion 2411 is set as an abutting portion 2414. By providing the abutting portion 2414, when the external thread connecting portion 2411 and the internal thread connecting portion 2421 are fully screwed and just disengaged from the threaded connection, the end of the internal thread connecting portion 2421 can abut against the abutting portion 2414, that is, the width of the mating portion 2413 is adapted to the width of the internal thread connecting portion 2421, so that one end of the internal thread connecting portion 2421 of the operating portion 242 can abut against the abutting portion 2414 and the other end can abut against the external thread connecting portion 2411, avoiding axial movement between the operating portion 242 and the limiting rod 241.

[0049] Specifically, the outer diameter of the abutting portion 2414 is smaller than the outer diameter of the limiting portion 2412, so that the limiting portion 2412 can be placed in the limiting groove more smoothly.

[0050] It can be understood that the operation hole 225 is used to limit the axial movement of the limiting rod 241. In this embodiment, the sliding distance of the operating portion 242 in the operation hole 225 is not less than the length of the limiting portion 2412, that is, the operator can slide the operating portion 242 to completely move the limiting portion into the limiting mounting hole 224, avoiding interference between the limiting portion 2412 and the first housing 110 or the second housing 120 when the first housing 110 and the second housing 120 rotate relative to each other.

[0051] Preferably, the limiting component is further provided with an elastic member 243. One end of the elastic member 243 abuts against the inner wall of the limiting mounting hole 224, and the other end abuts against the limiting rod 241. By providing the elastic member 243, it is used to make the limiting rod 241 have a tendency to move towards at least partially protruding from the limiting mounting hole 224, thereby ensuring that the limiting portion 2412 is stably located in the limiting groove, and further ensuring the reliability of the connection between the housing body 100 and the connecting device 200.

[0052] Exemplarily, the elastic member 243 is arranged as a spring. A positioning section 2415 is provided at one end of the limiting rod 241 away from the limiting portion 2412. The outer diameter of the positioning section 2415 is smaller than the outer diameter of the limiting rod 241 and smaller than the inner diameter of the elastic member 243. The spring is sleeved on the positioning section 2415. By providing the positioning section 2415, on the one hand, it is used for the abutting and positioning of the spring, and on the other hand, it provides guidance for the compression of the spring.

[0053] The use process of the above-mentioned limiting component is as follows: In the natural state, the elastic member 243 drives the limiting portion 2412 to protrude from one end of the second housing 220; when it is necessary to lock or open the first housing 110 and the second housing 120, the operator drives the operating portion 242 to compress the elastic member 243, so that the limiting rod 241 slides axially until the limiting portion 2412 retracts into the limiting mounting hole 224; then the operator correspondingly operates the first housing 110 to open or buckle relative to the second housing 220, so that the limiting groove of the first housing 110 corresponds to the limiting mounting hole 224 or is offset relative to the limiting mounting hole 224; then the operator relaxes the operating portion 242, and the elastic member 243 resets, so that the limiting portion 2412 is placed in the limiting groove or disengaged from the limiting groove.

[0054] This embodiment also discloses a handheld laser welding gun, which is provided with a welding gun housing as described in any of the above solutions, and the welding gun housing can be quickly disassembled and assembled.

[0055] This embodiment also discloses a laser processing device, including the handheld laser welding gun as described in any of the above solutions.

[0056] As Figures 7 - 11 shown, in other embodiments, the connecting device 200 is further provided with a locking component for realizing the quick-disassembly connection between the first housing 210 and the second housing 220.

[0057] Specifically, the first housing 210 and the second housing 220 can be snap-fitted to form an installation cavity penetrating along the first direction. The installation cavity is used to accommodate the armored cable, and the first housing 210 and / or the second housing 220 are used to connect to the outer shell of the welding torch. The locking assembly includes a locking rod 231 and a locking buckle 232. Among the first housing 210 and the second housing 220, the locking rod 231 is slidably disposed on one of them, and the locking buckle 232 is disposed on the other. The locking rod 231 can cooperate with the locking buckle 232 to snap and lock the first housing 210 and the second housing 220. The locking rod 231 can be disengaged from the locking buckle 232 to enable the first housing 210 and the second housing 220 to be selectively opened or snapped together.

[0058] By providing an installation cavity in the connecting device 200 and setting the first housing 210 and / or the second housing 220 of the connecting device 200 to be connected to the outer shell of the welding torch, the armored cable can be placed in the installation cavity and connected to the outer shell of the welding torch. The connecting device 200 is also provided with a locking assembly. The locking rod 231 of the locking assembly can cooperate with the locking buckle 232 to form a locked position. At this time, the cooperating locking rod 231 and locking buckle 232 can snap and lock the first housing 210 and the second housing 220 relative to each other, which can improve the connection reliability between the armored cable and the outer shell body 100. The locking rod 231 of the locking assembly can be disengaged from the locking buckle 232 to form an unlocked position. At this time, the disengaged locking rod 231 and locking buckle 232 can enable the first housing 210 and the second housing 220 to be relatively opened or snapped together, for replacing or maintaining accessories such as the laser output head, optical fiber, armored cable, etc., to achieve quick disassembly and assembly. Specifically, the locking assembly includes a locking rod 231 and a locking buckle 232 respectively disposed on the first housing 210 and the second housing 220. Among them, the locking rod 231 can be locked or unlocked with the locking buckle 232 by sliding, thereby realizing the conversion of the locking assembly between the locked position and the unlocked position. The above-mentioned connecting device 200 can achieve quick locking and quick unlocking without additional connecting parts and tools, facilitating the disassembly and assembly of related devices, and saving more time and effort.

[0059] In this embodiment, the second housing 220 is connected to the second outer shell 120. A limiting groove is provided on the first outer shell 110. The limiting rod 241 is slidably disposed on the second housing 220. At this time, the first outer shell 110 and the second outer shell 120 can be separately opened and closed, and at the same time, the first outer shell 110 and the second outer shell 120 can be snap-locked through the limiting assembly. In other embodiments, the limiting rod 241 can also be slidably disposed on the first housing 210. At this time, the first outer shell 110 and the second outer shell 120 can be opened or closed synchronously with the first housing 210 and the second housing 220.

[0060] Regarding the rotational connection between the first housing 210 and the second housing 220, as well as between the first outer shell 110 and the second outer shell 120, it can be a hinge connection or a snap connection. When the two are snap-connected, they can not only be opened relatively but also separated from each other.

[0061] In this embodiment, the locking rod 231 is disposed on the first housing 210. Specifically, a locking rod mounting hole 211 is provided on the first housing 210, and the locking rod 231 slidably passes through the locking rod mounting hole 211, and the locking buckle 232 is disposed on the second housing 220.

[0062] Further, an avoidance groove 212 is provided on the plane where the first housing 210 cooperates with the second housing 220. The avoidance groove 212 communicates with the locking rod mounting hole 211. Specifically, the locking buckle 232 is disposed on the plane where the second housing 220 cooperates with the first housing 210. When the first housing 210 and the second housing 220 are buckled, the locking buckle 232 can pass through the avoidance groove 212 and cooperate with or disengage from the locking rod 231.

[0063] Specifically, a locking ring 2311 is circumferentially protruded on the locking rod 231. The locking buckle 232 is provided with a locking groove 2321 and a notch 2322 communicating with the locking groove 2321. The width of the notch 2322 is greater than the outer diameter of the locking rod 231 and less than the outer diameter of the locking ring 2311, so that when the first housing 210 and the second housing 220 are buckled, the locking rod 231 can enter the locking groove 2321 from the notch 2322. When the locking rod 231 is axially moved, the locking ring 2311 is placed in the locking groove 2321. It can be understood that when the locking ring 2311 is placed in the locking groove 2321, it is the position where the locking rod 231 is locked with the locking buckle 232. At this time, the locking assembly is in the locked position, and the first housing 210 and the second housing 220 are locked and cannot be opened.

[0064] Preferably, two or more locking rings 2311 are provided at intervals along the axial direction of the locking rod 231 to improve the locking reliability. It can be understood that the locking buckle 232, the avoidance groove 212 and the locking ring 2311 are arranged in one-to-one correspondence, so the number of the locking buckle 232 and the avoidance groove 212 is set to be the same as that of the locking ring 2311.

[0065] Further, to achieve the connection between the locking rod 231 and the lock rod mounting hole 211, the lock rod mounting hole 211 is provided with a mounting end and a locking end, and the inner diameter of the mounting end is smaller than that of the locking end. At the same time, the mounting end is provided with an internal thread section 2111, and a smooth hole section 2112 is arranged on one side of the internal thread section 2111 away from the locking end. One end of the locking rod 231 is provided with an external thread section 2312. That is, during installation, the external thread section 2312 of the locking rod 231 penetrates into the lock rod mounting hole 211 from the locking end to the mounting end, so that the external thread section 2312 can be threadedly connected with the internal thread section 2111, and the external thread section 2312 needs to be fully screwed and pass through the internal thread section 2111 so that the external thread section 2312 can slide in the smooth hole section 2112. It should be noted that to ensure that the external thread section 2312 can slide in the smooth hole section 2112, the inner diameter of the smooth hole section 2112 is set to be larger than the outer diameter of the external thread section 2312. To prevent the limiting rod 241 from disengaging from the limiting mounting hole 224, the outer diameter of the locking ring 2311 is larger than the inner diameter of the internal thread section 2111.

[0066] Preferably, the locking assembly is further provided with a reset member 233. One end of the reset member 233 abuts against the end of the internal thread section 2111 away from the smooth hole section 2112, and the other end abuts against the locking ring 2311 close to the external thread section 2312. By providing the reset member 233, the locking rod 231 has a tendency to move towards the end away from the internal thread section 2111. That is, the setting of the reset member 233 can place the locking ring 2311 of the locking rod 231 in the locking buckle 232 to ensure that the locking assembly is stably placed in the locked position. Exemplarily, the reset member 233 is set as a spring. The spring is sleeved on the locking rod 231 from the internal thread section 2111 and abuts against a locking ring 2311 close to the internal thread section 2111. In other embodiments, the spring can be replaced with an elastic and deformable component such as an airbag, or can be replaced with a magnetic member to utilize the same-pole repulsion force to achieve the self-locking of the locking rod 231.

[0067] It is worth noting that an operating section 2313 is provided at one end of the locking rod 231 away from the external thread section 2312. When the locking assembly is placed in the locking position, the operating section 2313 is at least partially protruded from the locking rod mounting hole 211. By providing the operating section 2313 that can be protruded from the locking rod mounting hole 211, it is convenient for an operator to operate the locking rod 231 to move it axially. In a natural state, the locking assembly is placed in the locking position, the positions of the locking ring 2311 and the locking buckle 232 correspond, and the operating section 2313 is protruded from the locking rod mounting hole 211. When it is necessary to operate the locking assembly to the unlocking position, the operator drives the operating section 2313 to move the locking rod 231 axially and squeeze the reset member 233. At this time, the positions of the locking ring 2311 and the locking buckle 232 are staggered, so that when the first shell 210 and the second shell 220 are engaged, the locking rod 231 can enter the locking buckle 232 from the notch 2322. Then the operator releases the operating section 2313, the reset member 233 drives the locking rod 231 to reset, and the locking ring 2311 enters the locking groove 2321, completing the conversion of the locking assembly from the unlocking position to the locking position. At this time, the first shell 210 is engaged and locked relative to the second shell 220.

[0068] Furthermore, a hanging ring 213 is provided on the first housing 210 for hanging and storing the connecting device 200. A hook 221 is provided on the second housing 220 for passing linear consumables (such as welding wire, etc.) and air pipes, etc. At the same time, the hanging ring 213 and the hook 221 are both rotatably arranged, so that when the hanging ring 213 and the hook 221 are not in use, the hanging ring 213 and the hook 221 can be buckled with the first housing 210 or the second housing 220 to ensure a neat and beautiful appearance.

[0069] In other embodiments, the inner walls of the first shell 210 and the second shell 220 are both provided with positioning grooves 222, so that when the first shell 210 and the second shell 220 are buckled together, the inner wall of the installation cavity is formed with a positioning ring groove, which is provided to cooperate with the positioning ring protrusion of the armor cable sleeve 300. It can be understood that the armor cable sleeve 300 is sleeved on the outside of the armor cable to avoid damage caused by excessive bending of the part of the armor cable that cooperates with the end of the connecting device 200.
