Description

Technical Field

[0001] This utility model relates to a welding device, and more particularly to a welding device for welding furnace frames. Background Technology

[0002] The stove frame is used in gas stoves to support and carry cookware. The stove frame is generally composed of a support plate and a connecting ring. When processing the stove frame, workers usually weld the support plate to the connecting ring using a welding device.

[0003] In existing technologies, such as the furnace frame welding fixture disclosed in CN209936192U, furnace plates are placed into the furnace frame grooves. By rotating and pressing the rotating handle downwards, the larger diameter end of the clamping cam rotates to squeeze the end of the top rod, clamping the furnace plates. After clamping three furnace plates, another clamping part tightens the handle to the right, which is connected to the clamping table via a threaded rod, causing the threaded rod to move forward. This causes the positioning clamping block to clamp the furnace plates. Then, the furnace ring is placed in the groove at the top of the furnace ring positioning frame. The positioning is accurate and precise. Four furnace plates can be installed and welded simultaneously. It is simple to use, highly efficient, and reduces costs.

[0004] However, it still has some shortcomings, such as its welding fixtures being unable to weld furnace frames of different sizes, thus limiting its application range. Utility Model Content

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a welding equipment for furnace frame welding, including a worktable, a welding mechanism mounted on the worktable, and a limiting mechanism. The limiting mechanism is used to fix and limit the support frame and connecting ring. The welding mechanism is used to weld the support frame and connecting ring on the limiting mechanism. The limiting mechanism includes a driving device, which is mounted at the bottom of the worktable, and the output end of the driving device passes through the worktable and is located at the top of the worktable; a turntable, which is mounted at the top of the worktable, and the bottom of the turntable is connected to the output end of the driving device. A drive mechanism controls a turntable to rotate on a worktable. Multiple moving slots are circumferentially arranged around the center point of the turntable. A moving seat is slidably mounted in each moving slot. A moving plate is mounted on the left and right side walls of each moving seat. A sliding groove is provided on the wall of each moving slot to slidably connect with the moving plate.

[0012] A further preferred embodiment of this utility model is that the clamping plate has an elastic layer on each of its adjacent side walls.

[0013] A further preferred embodiment of this utility model is that the top of each clamp is chamfered.

[0014] Compared with the prior art, the advantages of this utility model are that, through its design, when processing furnace frames of different sizes, the operator first moves the position of the clamping seats on the turntable according to the diameter of the connecting ring (for example, when welding a large furnace frame, the operator moves multiple clamping seats away from each other along the moving groove, while when welding a small furnace frame, the operator moves multiple clamping seats closer to each other along the moving groove).

Detailed Implementation

[0018] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0019] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0020] This embodiment mainly describes the structure of a welding equipment for furnace frame welding, as detailed below: like Figures 1-5As shown, a welding device for welding a furnace frame includes a workbench 1, a welding mechanism 2 and a limiting mechanism 3 installed on the workbench 1. The limiting mechanism 3 is used to fix and limit the support frame 6 and the connecting ring 4, while the welding mechanism 2 is used to weld the support frame 6 and the connecting ring 4 on the limiting mechanism 3. Thus, when welding the furnace frame, the support frame 6 and the connecting ring 4 are first placed on the limiting mechanism 3 in sequence, and then the welding mechanism 2 is started to weld the support frame 6 and the connecting ring 4 on the limiting mechanism 3, thereby completing the welding of the furnace frame. The limiting mechanism 3 includes a drive device 31 installed at the bottom of the worktable 1, with the output end of the drive device 31 passing through the worktable 1 and located at the top of the worktable 1. A turntable 32 is then installed at the top of the worktable 1, with its bottom connected to the output end of the drive device 31. Thus, when the drive device 31 is working, it can control the turntable 32 to rotate on the worktable 1. Multiple moving grooves 34 are circumferentially formed around the center point of the turntable 32, and each moving groove 34 is slidably positioned within it. There is a movable seat 36, and a clamping seat 33 for clamping the support frame 6 is provided on each movable seat 36. A movable plate 37 is provided on the side wall on the left and right sides of the movable seat 36. A sliding groove 341 that is slidably connected to the movable plate 37 is opened on the groove wall of the movable groove 34. Finally, a plurality of screw holes communicating with the sliding groove 341 are evenly arranged on the turntable 32 at the top of the sliding groove 341 along the length of the sliding groove 341, and bolts 35 that abut against the top of the movable plate 37 are provided in the screw holes. In this way, when processing furnace frames of different sizes, the operator first moves the clamping seat 33 on the turntable 32 according to the diameter of the connecting ring 4. (For example, when welding a large furnace frame, the operator moves multiple clamping seats 33 away from each other along the moving groove 34, while when welding a small furnace frame, the operator moves multiple clamping seats 33 closer to each other along the moving groove 34). After the position of the clamping seat 33 is adjusted, the operator screws the bolts 35 into the screw holes above the moving plate 37 until the bolts 35 press against the moving plate 37. This ensures the stability of the clamping seat 33 on the turntable 32. Then, multiple support frames 6 are placed into the clamping seats 33 and clamped in place. Next, the connecting ring 4 is placed on top of the clamping seat 33. When the connecting ring 4 is on the clamping seat 33, the support frame 6 can be inserted into the mounting hole on the connecting ring 4. In this way, the limiting mechanism 3 can limit the connecting ring 4 of different sizes. Finally, the welding mechanism 2 is started to weld the support frame 6 and the connecting ring 4 located in the mounting hole. In this way, the welding equipment can weld furnace frames of different sizes, thereby improving the application range of the welding equipment. In order to facilitate the welding of the support frame 6 and the connecting ring 4 in different clamping seats 33, the operator can control the drive device 31 to rotate the turntable 32. As the turntable 32 rotates, the welding mechanism 2 can weld the support frame 6 on different clamping seats 33, which facilitates the welding mechanism 2 to weld the furnace frame.

[0021] Furthermore, in order to facilitate the placement of the connecting ring 4, two placement seats 7 for placing the connecting ring 4 are respectively provided on the clamping seat 33. In order to make the placement seat 7 have a limiting function, a groove 71 is provided on the top of each placement seat 7, and the connecting ring 4 is located in the groove 71.

[0022] Furthermore, in order to improve the stability of the turntable 32 when it rotates, a number of balls 5 are evenly arranged between the bottom of the turntable 32 and the top of the worktable 1. At the same time, an annular guide groove is opened on both the bottom of the turntable 32 and the top of the worktable 1, and the balls 5 are all located in the guide groove.

[0023] Each clamping seat 33 includes a seat body 331 mounted on top of the movable seat 36. The seat body 331 has an open mounting groove 332 at its top. Two clamping plates 334 are symmetrically arranged in the mounting groove 332. Multiple hydraulic telescopic rods 333 are evenly arranged on the left and right sides of the groove walls. The telescopic ends of the hydraulic telescopic rods 333 are connected to the side walls of the clamping plates 334. When fixing the support frame 6, the hydraulic telescopic rods 333 are first shortened. Then, the operator inserts the support frame 6 into the mounting groove 332 through the opening, positioning the support frame 6 between the two clamping plates 334. The hydraulic telescopic rods 333 are then extended, allowing the clamping plates 334 to clamp the support frame 6.

[0024] Furthermore, in order to insert the support frame 6 into the mounting slot 332, the top of the clamping plates 334 are all chamfered. At the same time, to improve the stability of the clamping plates 334 in holding the support frame 6, an elastic layer 335 made of high-temperature resistant silicone is provided on each adjacent side wall of the clamping plates 334. The welding mechanism 2 includes a mounting frame 21 mounted on the workbench 1 in an inverted L-shape. A screw moving assembly 22 is provided on the top of the mounting frame 21, with the top of the mounting frame 21 facing the direction along the moving groove 34. A first mounting plate 23 is provided on the inner side of the top of the mounting frame 21, and the top of the first mounting plate 23 is connected to the moving block in the screw moving assembly 22. In this way, the screw moving assembly 22 can control the first mounting plate 23 to move back and forth on the top of the mounting frame 21. Two telescopic devices 24 with telescopic ends facing the workbench 1 are provided at the bottom of the first mounting plate 23. Finally, a second mounting plate 26 is provided at the telescopic end of the telescopic device 24, and a welding torch 25 for welding is provided on the second mounting plate 26. Therefore, when the welding mechanism 2 is in use, the lead screw moving assembly 22 is first activated, causing the moving block in the lead screw moving assembly 22 to move the first mounting plate 23, the telescopic device 24, the second mounting plate 26, and the welding torch 25 toward the clamping seat 33 until the welding torch 25 moves above the connecting ring 4. Then, the telescopic device 24 is activated to extend the telescopic device 24. In this way, the welding torch 25, which is mounted on the telescopic end of the telescopic device 24 via the second mounting plate 26, can move toward the support frame 6 on the clamping seat 33 until the working end of the welding torch 25 is close to the mounting hole on the connecting ring 4. Then, the welding torch 25 is activated to complete the welding of the support frame 6 and the connecting ring 4. The lead screw moving assembly 22 and the welding torch 25 are both existing mature technologies, so they are not described in detail in this utility model.
