Detailed implementation mode

[0040] The following further elaborates on this application Figures 1-9 with reference to the attached drawings.

[0041] The embodiment of this application discloses a welding device.

[0042] Embodiment 1:

[0043] Referring to Figure 1 , the welding device includes a CNC machine tool 1, an electric welding gun 2 and a welding gun fixture 3. The CNC machine tool 1 includes a workbench 11, a machine head 12 and a PLC controller (not marked in the figure). The electric welding gun 2 is fixedly connected to the welding gun fixture 3, and the welding gun fixture 3 is fixedly connected to one end of the machine head 12 close to the workbench 11. Among them, the machine head 12 moves in the X-axis, Y-axis and Z-axis directions through the PLC controller, and the electric welding gun 2 is automatically controlled to switch on and off through the PLC controller.

[0044] Referring to Figure 2 and Figure 3 , specifically, the welding gun fixture 3 includes a mounting frame 31, a heating chuck 32 and a connecting column 33. The mounting frame 31 is in a rectangular frame shape and is fixedly connected to the lower end of the machine head 12. The heating chuck 32 is in a circular tubular shape. The upper end of the heating chuck 32 is fixedly connected to the connecting column 33, and the connecting column 33 is fixedly connected to the lower end of the mounting frame 31 through bolts. Four through grooves 321 are spaced apart along the circumferential direction of the lower end of the heating chuck 32, and the heating chuck 32 has a certain elasticity to realize the clamping and fixing of nuts. Among them, the electric welding gun 2 is fixedly connected to the inside of the mounting frame 31, and the gun head of the electric welding gun 2 extends into the inside of the heating chuck 32 to realize the heating of the heating chuck 32.

[0045] In actual work, the nut is inserted into the heating chuck 32 manually or by a feeding device, and the heating chuck 32 clamps the nut, and then the metal shower panel 6 is placed on the workbench 11. Afterwards, the PLC controller controls the movement of the machine head 12 to drive the mounting frame 31 and the electric welding gun 2 to move, so that the nut is pressed against the surface of the metal shower panel 6. In addition, the PLC controller controls the opening of the electric welding gun 2, and the gun head of the electric welding gun 2 heats the heating chuck 32, so that the heating chuck 32 heats the nut and the contact point between the nut and the metal shower panel 6, so as to achieve welding and fixing the nut to the metal shower panel 6.

[0046] In this process, there is no need to use a tool to clamp the nut, and the operation is simple and convenient, so it is easy to weld the nut to the metal shower panel 6. In addition, the CNC machine tool 1 is used for welding, and there is no need for manual welding of the nut, which improves the safety and efficiency of the work and the accuracy of welding.

[0047] Reference Figure 4 and Figure 5 Furthermore, it also includes a fastening fixture 4, which includes a placement plate 41 and a plurality of positioning columns 42. The placement plate 41 is fixedly connected to the workbench 11. In this embodiment, the number of the positioning columns 42 is two, and the two positioning columns 42 are fixedly connected to the upper side of the placement plate 41 and are spaced apart along the length direction of the placement plate 41.

[0048] In addition, the upper side of the placement plate 41 is recessed downward to form an embedding groove 411, which is used to place the metal shower panel 6. Two positioning columns 42 are penetrated through the water outlet of the metal shower panel 6, so that the metal shower panel 6 is positioned and limited to ensure the accuracy of the placement of the metal shower panel 6, thereby improving the accuracy of nut welding.

[0049] In addition, the fastening fixture 4 also includes a plurality of quick clamps 43, which are fixedly connected to the upper side of the placement plate 41 and arranged at intervals along the circumference of the metal shower panel 6. Each quick clamp 43 is pressed against the upper side of the metal shower panel 6 to avoid the heating chuck 32 from driving the metal shower panel 6 to move after the nut welding is completed, thereby ensuring the stability of the welding work.

[0050] The implementation principle of this embodiment is as follows: In actual work, nuts are inserted into the heating chuck 32 manually or by a feeding device. The heating chuck 32 clamps the nuts, and then the metal shower panel 6 is placed on the workbench 11. After that, the PLC controller controls the movement of the machine head 12 to drive the mounting bracket 31 and the electric welding gun 2 to move, so that the nuts are pressed against the surface of the metal shower panel 6. Moreover, the PLC controller controls the opening of the electric welding gun 2, and the gun head of the electric welding gun 2 heats the heating chuck 32, so that the heating chuck 32 heats the nuts and the contact part between the nuts and the metal shower panel 6, to weld and fix the nuts on the metal shower panel 6.

[0051] During this process, there is no need to use tooling to clamp the nuts, and the operation is simple and convenient, thus facilitating the welding of the nuts to the metal shower panel 6. Moreover, by using the CNC numerical control machine tool 1 for welding, there is no need for manual welding of the nuts, which improves the work safety and efficiency, and also improves the welding precision.

[0052] Embodiment 2:

[0053] Referring to Figure 6 and Figure 7 This embodiment is the same as Embodiment 1 in other structures. The difference lies in the different pressing methods for the metal shower panel 6. Specifically, the fastening fixture 4 further includes four pressing components 44, and the four pressing components 44 are distributed in a rectangular shape. Among them, the pressing component 44 includes a pressing block 441 and a first spring 442. Two first installation grooves 412 are respectively opened on both side walls of the placement plate 41 located in the embedding groove 411. The pressing block 441 and the first spring 442 are located in the first installation groove 412. One end of the first spring 442 is fixedly connected to the pressing block 441, and the other end is fixedly connected to the bottom wall of the placement plate 41 located in the first installation groove 412, so as to drive the pressing block 441 to partially protrude from the first installation groove 412 to realize the pressing of the metal shower panel 6. It should be noted that the depth of the embedding groove 411 of the placement plate 41 is greater than the thickness of the metal shower panel 6.

[0054] In actual work, by pressing each pressing block 441 and then placing the metal shower panel 6 in the embedding groove 411, each pressing block 441 protrudes from the first installation groove 412 under the action of each first spring 442 and presses against the upper side of the metal shower panel 6 to realize the fixation of the metal shower panel 6. The operation is convenient and the structure is simple. At the same time, a guiding surface 441a is provided at one end of the pressing block 441 away from the first spring 442, and the guiding surface 441a is inclined. When the metal shower panel 6 abuts against the guiding surface 441a, the pressing block 441 is pressed into the first installation groove 412 to facilitate the placement of the metal shower panel 6 in the embedding groove 411.

[0055] Further, the pressing component 44 further includes two second springs 443 and four pull ropes 444. The placing plate 41 is provided with two second mounting grooves 413 at the bottom wall of the embedding groove 411. The two positioning columns 42 are vertically and slidably arranged in the two second mounting grooves 413 respectively. One end of each second spring 443 is fixedly connected to the lower end of the positioning column 42, and the other end is fixedly connected to the bottom wall of the placing plate 41 at the second mounting groove 413 to drive the positioning column 42 to move upward. The four pull ropes 444 are respectively arranged in one-to-one correspondence with the four pressing blocks 441. One end of the pull rope 444 is fixedly connected to one end of the pressing block 441 close to the first spring 442, and the other end is fixedly connected to the positioning column 42. The pull rope 444 movably penetrates through the placing plate 41. It should be noted that the diameter of the second mounting groove 413 is slightly larger than the diameter of the positioning column 42 to facilitate the passing of the pull rope 444.

[0056] After the metal shower panel 6 is welded with nuts, by pressing the two positioning columns 42, each positioning column 42 drives the two pull ropes 444 to pull the two corresponding pressing blocks 441, so that each pressing block 441 is pressed into each first mounting groove 412, realizing the release of the pressing of the metal shower panel 6 by each pressing block 441, so as to facilitate the removal of the metal shower panel 6 in the embedding groove 411. Then, each pressing block 441 is reset under the action of each first spring 442, and each positioning column 42 is reset under the action of each second spring 443 to facilitate the placement of the next metal shower panel 6.

[0057] Refer to Figure 8 Further, the pressing component 44 further includes an ejecting post 445 and a third spring 446. The placing plate 41 is provided with a third mounting groove 414 at the bottom wall of the embedding groove 411. The ejecting post 445 and the third spring 446 are located in the third mounting groove 414. One end of the third spring 446 is fixedly connected to the lower end of the ejecting post 445, and the other end is fixedly connected to the bottom wall of the placing plate 41 at the third mounting groove 414 to drive the ejecting post 445 to move upward. When each pressing block 441 releases the pressing of the metal shower panel 6, the ejecting post 445 ejects the metal shower panel 6 under the action of the third spring 446 to facilitate the removal of the metal shower panel 6.

[0058] Refer to Figure 9Moreover, the welding device further includes a material taking member 5 to facilitate the taking out of the metal shower panel 6. Specifically, the material taking member 5 includes a material resisting plate 51 and two abutting columns 52. The two abutting columns 52 are fixedly connected to one side of the material resisting plate 51, and the two abutting columns 52 are arranged in one-to-one correspondence with the two positioning columns 42. During operation, each abutting column 52 presses against each positioning column 42, so that the pulling rope 444 drives each pressing block 441 to press into the first installation groove 412. The metal shower panel 6 is ejected under the action of the ejecting column 445 and the third spring 446, facilitating the taking out of the metal shower panel 6. At the same time, when the metal shower panel 6 is ejected, it abuts against the material resisting plate 51, minimizing the risk of the metal shower panel 6 popping out and being damaged, ensuring the stable removal of the metal shower panel 6.

[0059] The implementation principle of this embodiment is as follows: When it is necessary to take out the metal shower panel 6, the two abutting columns 52 of the material taking member 5 press the two positioning columns 42, causing the two positioning columns 42 to move downward and compress the two second springs 443. The two positioning columns 42 press the four pressing blocks 441 into the first installation groove 412 through the four pulling ropes 444. At this time, the four pressing blocks 441 release the pressing on the metal shower panel 6, and the third spring 446 drives the ejecting column 445 to move upward to eject the metal shower panel 6. The structure is simple and the operation is convenient, facilitating the taking out of the metal shower panel 6. Moreover, when the metal shower panel 6 is ejected, the material resisting plate 51 abuts against the metal shower panel 6, minimizing the risk of the metal shower panel 6 popping out and being damaged, ensuring the stable removal of the metal shower panel 6.

[0060] The above are all the preferred embodiments of this application.
