[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-5 The present invention provides the following technical solution:

[0026] A welding machine with a quick-change welding torch includes a placement component 1, a robotic arm welding machine 2 is bolted to the top of the placement component 1, a mounting component 3 is provided on the front side of the robotic arm welding machine 2, and a welding torch body 4 is provided inside the mounting component 3.

[0027] The mounting assembly 3 includes a mounting block 301. Fixing blocks 302 are welded to the top and bottom of the inner wall of the mounting block 301. Sliding rods 303 are slidably connected inside the two fixing blocks 302. Control blocks 304 are fixedly connected to opposite sides of the two sliding rods 303. Limiting plates 305 are fixedly connected to opposite sides of the two limiting plates 305. Return springs 306 are fixedly connected to opposite sides of the two limiting plates 305. A splicing block 307 is provided inside the mounting block 301. Limiting grooves 308 that cooperate with the limiting plates 305 are provided at the top and bottom of the splicing block 307. The splicing block 307 is fixedly connected to the surface of the welding gun body 4.

[0028] In this embodiment: the placement component 1 provides support and adjustment for the robotic arm welding machine 2; the installation component 3 facilitates the connection between the welding gun body 4 and the robotic arm welding machine 2. The system includes an installation block 301, a fixing block 302, a sliding rod 303, a control block 304, a limiting plate 305, a return spring 306, a splicing block 307, and a limiting groove 308. First, when the user needs to install the welding gun body 4, the user manually aligns the pre-set locking block of the splicing block 307 with the locking groove on the inner wall of the installation block 301. Then, the user manually connects the splicing block 307 to the installation block 301. The inner wall of the mounting block 301 is contacted, and then the position of the splicing block 307 is moved, so that the height of the limiting plate 305 is adjusted, and the sliding rod 303 slides inside the fixing block 302. Then the limiting plate 305 contacts the inner wall of the limiting groove 308, and then the position of the sliding rod 303 is moved, thereby limiting the splicing block 307, so as to quickly install the welding gun body 4. When it is necessary to disassemble the welding gun body 4, the user manually adjusts the control block 304, so that the sliding rod 303 adjusts the limiting plate 305, and then manually moves the splicing block 307 away from the inner wall of the mounting block 301, thereby achieving the function of quick disassembly.

[0029] Specifically, such as Figure 3 As shown, the placement component 1 includes a box 101, and a storage slot 102 is provided on the top of the box 101. An electric telescopic rod body 103 is fixedly connected to the bottom of the inner wall of the storage slot 102. The electric telescopic rod body 103 is bolted to the bottom of the robotic arm welding machine 2.

[0030] Specifically, such as Figure 3 As shown, a circular plate 104 is fixedly connected to the surface of the electric telescopic pole body 103, and a shock-absorbing spring 105 is fixedly connected to the bottom of the circular plate 104.

[0031] Specifically, such as Figure 3 As shown, auxiliary grooves 106 are provided on the front and rear sides of the inner wall of the storage groove 102. Auxiliary blocks 107 are slidably connected to the inner walls of the two auxiliary grooves 106. The opposite sides of the two auxiliary blocks 107 are respectively bolted to the front and rear sides of the robotic arm welding machine 2.

[0032] In this embodiment: by setting up a housing 101, a storage slot 102, an electric telescopic rod body 103, a circular plate 104, and a shock-absorbing spring 105, the user can adjust the electric telescopic rod body 103 inside the housing 101, so that the electric telescopic rod body 103 can adjust the robotic arm welding machine 2 on the inner wall of the storage slot 102. When the electric telescopic rod body 103 resets to the position of the robotic arm welding machine 2, the circular plate 104 and the shock-absorbing spring 105 assist the robotic arm welding machine 2 in resetting in the storage slot 102. By setting up an auxiliary block 107 and an auxiliary slot 106, the robotic arm welding machine 2 can be assisted in moving in position in the storage slot 102.

[0033] Specifically, such as Figure 4 As shown, a bolt plate 5 is fixedly connected to the rear side of the housing 101, and a screw rod 6 is threaded inside the bolt plate 5. A limit block 7 is rotatably connected to the bottom of the screw rod 6.

[0034] Specifically, such as Figure 4 As shown, a protective pad 8 is fixedly connected to the bottom of the limiting block 7. The protective pad 8 is made of rubber.

[0035] In this embodiment: by setting the bolt plate 5, the spiral rod 6 and the limiting block 7, the user can manually adjust the spiral rod 6 so that the spiral rod 6 is adjusted inside the bolt plate 5, and then the bottom of the limiting block 7 contacts the ground, thereby achieving the function of limiting the structure. By setting the protective pad 8, the positional deviation of the structure can be reduced.

[0036] Specifically, such as Figure 5 As shown, a pull-out groove 9 is provided on the front side of the box 101, and a pull-out box 10 is slidably connected inside the pull-out groove 9. A partition plate 11 is fixedly connected inside the pull-out box 10.

[0037] Specifically, such as Figure 1 As shown, a push frame 12 is fixedly connected to the rear side of the box 101, and an anti-slip sleeve 13 is fitted on the surface of the push frame 12. A caster wheel 14 is fixedly connected to the bottom of the box 101.

[0038] In this embodiment: by setting a pull-out slot 9, a pull-out box 10 and a partition plate 11, the pull-out box 10 can be spliced ​​with the box body 101 through the pull-out slot 9, and the partition plate 11 is used to facilitate the user to place and store tools. By setting a push frame 12 and an anti-slip sleeve 13, the user can easily operate the box body 101. By setting universal wheels 14, the user can easily move and adjust the structure.

[0039] Working principle: When the welding gun body 4 needs to be installed, the user first aligns the splicing block 307 on the welding gun body 4 with the slot opened on the inner wall of the mounting block 301, so that the splicing block 307 contacts the inner wall of the mounting block 301. As the splicing block 307 is gradually inserted into the mounting block 301, the splicing block 307 will squeeze the limiting plate 305, causing the limiting plate 305 to drive the sliding rod 303 to slide inside the fixed block 302. At this time, the return spring 306 is compressed. When the splicing block 307 is fully inserted into the mounting block 301 and reaches the appropriate position, the limiting plate 305 is released by the elastic force of the return spring 306. The welding gun body 4 is inserted into the limiting grooves 308 at the top and bottom of the splicing block 307, thereby limiting the splicing block 307 and completing the quick installation of the welding gun body 4 and the robotic arm welding machine 2. When it is necessary to disassemble the welding gun body 4, the user manually applies external force to the control block 304. The control block 304 drives the sliding rod 303 to move, and the sliding rod 303 pushes the limiting plate 305 away from the limiting groove 308 of the splicing block 307, releasing the limitation of the splicing block 307. After that, the user can manually pull the splicing block 307 out of the inner wall of the mounting block 301 to achieve quick disassembly of the welding gun body 4.

[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
