[0053] The specific implementation of this technical solution will be further described in detail below with reference to the accompanying drawings. See also Figures 1-9 .

[0054] A special welding machine for gas stove frames, comprising:

[0055] A frame 1, on which a workbench 11 is mounted;

[0056] Positioning device 2, which is installed on the workbench 11, is used to position the support legs 101 and the furnace ring 102 of the furnace frame 100;

[0057] Several welding devices 3 are installed on the frame 1 and located around the positioning device 2 for welding operations on the furnace frame 100;

[0058] A pressing device 4 is installed on the frame 1 and is located above the positioning device 2, for pressing down the support foot 101 on the positioning device 2;

[0059] Demolding device 5, which is installed on the frame 1, is used to demold the welded furnace frame 100.

[0060] In this design, the welding device 3 is changed from the original planar contact (i.e., welding the support leg 101 and the bottom surface of the furnace ring 102) to side contact (i.e., welding the side end of the support leg 101 and the side end of the furnace ring 102), which reduces the welding contact area, thereby reducing the welding current, reducing the heat generation, saving welding electricity costs, and reducing the manufacturing cost of the furnace frame.

[0061] The positioning device 2 includes:

[0062] The base 21 is mounted on the workbench 11 and is used to support the lower end of the furnace ring 102;

[0063] The mold 22 is provided with several snap-fit ​​grooves 231 for snapping the upper part of the support foot 101, so that the lower part of the support foot 101 is located at the side end of the mold 22. By fitting the furnace ring 102 onto the mold 22, the lower outer side of the support foot 101 abuts against the inner side of the furnace ring 102. The welding device 3 performs welding operations on the abutment of the support foot 101 and the furnace ring 102.

[0064] The support plate 25, located between the base 21 and the mold 22, is used to connect the fixing component 1 and to bear the downward pressure of the pressing device 4;

[0065] During production, all the support legs 101 are placed on the mold 22, and then the furnace ring 102 is fitted onto the outside of the support legs 101. All the support legs 101 are welded onto the furnace ring 102 through several welding devices 3, thus forming the furnace frame 100. The clamping and welding are completed in one go, which greatly improves production efficiency.

[0066] The mold 22 is provided with a plurality of mounting slots 221, and a locking block 23 is provided in the mounting slot 221. The locking block 23 is provided with the locking groove 231. When the support foot 101 to be welded is of different sizes and models, it can be adapted by replacing the locking block 23 of different models. There is no need to replace the entire positioning device 2, which is convenient and simple to operate.

[0067] The mold 22 has several mounting slots 222, and a support block 24 is provided in each mounting slot 222. The end of the support block 24 extends out of the mold 22 and is used to movably abut against the support foot 101. By abutting the lower inner wall of the support foot 101 with the end of the support block 24, the lower outer wall of the support foot 101 abuts against the inner wall of the furnace ring 102, thus ensuring the stability of the welding.

[0068] The support block 24 is provided with a waist-shaped hole 241. The end of the fastener (bolt, screw or pin) passes through the waist-shaped hole 241 and is connected to the base 21. The length of the front end of the support block 24 extending out of the mold 22 can be adjusted by adjusting the position of the fastener in the waist-shaped hole 241. This ensures that when facing different types of support feet 101, the support block 24 can make the support feet 101 abut against the furnace ring 102, ensuring a firm and stable weld.

[0069] The bottom of the mounting groove 222 is provided with a clearance hole 223. The clearance hole 223 is located above the fixing member 1. The tightness of the fixing member 1 can be adjusted by the clearance hole 223, thereby adjusting the position of the support block 1 24 in the mounting groove 222. The clearance hole 223 makes it convenient to adjust the length of the support block 1 24 without having to remove the entire mold 22 from the base 21, making it convenient to use.

[0070] The base 21 is provided with a plurality of support blocks 26. The support blocks 26 are movably abutted against the lower end of the furnace ring 102 to separate the lower end of the furnace ring 102 from the upper end surface of the base 21. This prevents the welding device 3 from welding the furnace ring 102 and the base 21 together during welding, and also prevents the base 21 from being reduced in service life due to excessively high welding temperature and prolonged use.

[0071] The welding device 3 includes:

[0072] The drive component 31 is a cylinder, a linear motor, or an electric push rod, which is mounted on the frame 1.

[0073] The welding torch 32 is a prior art device. It is installed on the output end of the drive component 31, and the welding torch 32 is provided with a waist-shaped hole 33. A fixing component 2 (screw, bolt or pin) is provided in the waist-shaped hole 33. The end of the fixing component 2 is connected to the drive end of the drive component 31. The welding position of the welding torch 32 is adjusted by adjusting the position of the fixing component 2 in the waist-shaped hole 33.

[0074] The welding torch 32 is driven by the drive component 31 to approach and abut against the side end of the furnace frame 100, thereby performing welding operations on the furnace frame 100.

[0075] The frame 1 is provided with a plurality of fixing plates 14, which are distributed around the positioning device 2. Each fixing plate 14 is provided with an adjustment hole 141. The end of a fixing member (which is a screw, bolt, or pin) passes through the adjustment hole 141 and is connected to the rear end of the drive member 31. The welding position of the welding torch 32 is adjusted by adjusting the position of the fixing member on the fixing plate 14.

[0076] The pressing device 4 includes:

[0077] Drive component 2 41 (which is an electric push rod, a cylinder, or a linear motor) is mounted on the worktable 11;

[0078] Mounting bracket 42 is mounted on the driving end of the second driving component 41;

[0079] Several pressure members 43 are circumferentially distributed on the mounting frame 42, and the lower end of each pressure member 43 has a pressure part 431;

[0080] The mounting bracket 42 is driven to move downward by the second driving component 41, so that the pressing part 431 moves to abut against the upper end of the support foot 101 in the snap-fit ​​groove 231, so as to prevent the support foot 101 from shaking, and to ensure the stability of welding and the flatness of welding of furnace frame 100.

[0081] The frame 1 is provided with a plurality of guide rods 12, the upper end of the guide rods 12 is connected to an anti-detachment component 13, and the guide rods 12 are inserted through the mounting frame 42;

[0082] The drive component 41 is provided with a buffer limiter 411, which is a prior art. The buffer limiter 411 is movably abutted against the lower end of the mounting frame 42 to limit the downward movement distance of the mounting frame 42 and prevent the pressure part 431 from abutting the support foot 101 with excessive force.

[0083] The mounting bracket 42 is provided with a waist-shaped hole 441. The upper end of the pressing member 43 passes through the waist-shaped hole 441. The pressing member 43 is provided with a fixing member 432 (a nut or a snap ring). The fixing member 432 movably abuts against the edge of the waist-shaped hole 441, restricting the movement of the pressing member 43 on the waist-shaped hole 441. By adjusting the installation position of the pressing member 43 in the waist-shaped hole 441, the pressing member 43 can be ensured to be located above the snap-fit ​​groove 231.

[0084] The mounting frame 42 is provided with the welding device 3, and the lower end of the welding gun 32 of the welding device 3 extends movably out of the lower end of the mounting frame 42; the welding device 3 on the mounting frame 42 is used to weld multiple support legs 101 together, so that the support crossbar located in the middle of the furnace ring 102 is welded together with the support legs 101 on both sides.

[0085] The mounting bracket 42 has a first mounting plate 44 and a second mounting plate 45. The first mounting plate 44 is provided with an opening 442 and the pressure member 43. The second mounting plate 45 is provided with an opening 451 and the welding device 3. Several adjustment holes 452 are provided on the edge of the opening 451. A fixing plate 453 is connected to the adjustment holes 452. The fixing plate 453 is provided with an adjustment hole 454. The welding device 3 is connected by the end of a fixing member (screw, bolt or pin) passing through the adjustment hole 454. The welding device 3 is movably placed in the opening 442 and the opening 451. By adjusting the installation position of the fixing plate 453 in the adjustment hole 452 and the installation position of the welding device 3 in the adjustment hole 454, the position of the welding device 3 above the positioning device 2 can be adjusted.

[0086] When the mounting bracket 42 moves down so that the pressing element 43 abuts against the upper end of the support foot 101 in the snap groove 231, the welding device 3 performs welding operations on the support crossbar in the middle of the furnace ring 102 and the support feet 101 on both sides.

[0087] The base 21 has several clearance openings 211 on its edge; the demolding device 5 includes:

[0088] The drive component 3 51 (which is a pneumatic cylinder, hydraulic cylinder, or electric push rod) is installed at the lower end of the worktable 11;

[0089] Connecting plate 52, which is movably connected to the driving end of the driving component 51;

[0090] Several connecting rods 53 are circumferentially distributed on the upper end of the connecting plate 52, and the upper ends of the connecting rods 53 pass through the workbench 11 and are movably placed in the clearance opening 211;

[0091] The detachment module 54 is installed at the upper end of the connecting rod 53, and the detachment module 54 is movably placed in the clearance opening 211 and movably abuts against the lower end of the furnace ring 102, for the purpose of detaching the furnace frame 100 from the positioning device 2.

[0092] When welding is completed, the drive component 51 causes the connecting rod 53 to move upward, thereby causing the demolding module 54 to abut against the lower end of the furnace frame 100, so that the furnace frame 100 is disengaged from the positioning device 2. This facilitates demolding of the welded furnace frame 100, improves efficiency, and reduces the labor intensity of manual demolding.
