[0002] Welding, also known as fusion welding, is a manufacturing process and technology that joins metals or other plastic materials by heating, high temperature or high pressure. Welding of ring-shaped metal parts is mostly done manually, usually requiring two people to work together. First, the two parts are spot welded together, and then a through welding process is carried out.

[0004] The above-mentioned device can only weld parts of a specific size. When the part size is large, the part will be unstable, which will affect the welding accuracy. Therefore, we propose a ring welding auxiliary device. Utility Model Content

[0005] This utility model addresses the shortcomings of existing technologies by providing a ring welding auxiliary device. By setting a turntable on the base and setting multiple slots on the turntable for sliding blocks to slide, a drive assembly drives the lead screws in all the slots to rotate simultaneously, which can drive the slide blocks to move outward at the same time. A clamping assembly is used to clamp larger ring-shaped parts.

[0006] To solve the above-mentioned technical problems, the present invention addresses the issue that existing devices for clamping ring-shaped parts are only applicable to parts of a specific size and have limited applicability through the following technical solution.

[0033] Example:

[0034] Please see Figures 1-6 A ring welding auxiliary device includes a base 1, a slide 4, and a drive assembly 8. A turntable 2, controlled by an external controller, is rotatably mounted in the middle of the base 1. A welding torch 3 is mounted on the outer side of the base 1. An electric push rod 17 is fixedly mounted at the tail of the welding torch 3. A hydraulic cylinder 18 is fixedly mounted at the bottom of the electric push rod 17. The bottom of the hydraulic cylinder 18 is fixedly mounted inside the base 1. The height of the welding torch 3 is adjusted by the hydraulic cylinder 18 to ensure that the welding torch 3 can weld at different heights of the ring part. The distance between the welding torch 3 and the outer side of the ring part can be adjusted by the electric push rod 17 to ensure welding quality. The top of the turntable 2 has multiple slots 5. A lead screw 6 is rotatably mounted in the slots 5. The slide 4 is slidably mounted in the slots 5 under the control of the lead screw 6. A clamping assembly 7 for clamping the ring part is mounted on the top of the slide 4. The drive assembly 8 for driving the lead screw 6 to rotate is mounted on the turntable 2.

[0035] The following describes some embodiments of this application in detail with reference to the accompanying drawings:

[0036] Please see Figures 1-6 By setting a turntable 2 on the base 1, and setting multiple slots 5 on the turntable 2 for sliding blocks 4, the drive assembly 8 drives the lead screws 6 in all slots 5 to rotate simultaneously, which can drive the blocks 4 to move outwards at the same time, and use the clamping assembly 7 to clamp larger ring-shaped parts.

[0037] The drive assembly 8 includes a drive motor 9, which is fixedly mounted on the bottom of the turntable 2. Furthermore, the slots 5 are arranged in an equilateral triangle on the turntable 2. When the slide block 4 moves and clamps the annular part through the clamping block 15, it ensures the uniformity of the force applied to the annular part by the support frame 13. A connecting groove 10 is provided at the connection of the three slots 5. The connecting groove 10 is located in the turntable 2. A first bevel gear 11 is rotatably mounted in the connecting groove 10. The output end of the drive motor 9 is fixed to the gear shaft of the first bevel gear 11. The end of the lead screw 6 near the connecting groove 10 passes through the slot 5 and is fixedly mounted with a second bevel gear 12. The second bevel gear 12 meshes with the first bevel gear 11.

[0038] Furthermore, the clamping assembly 7 includes a support frame 13, which is fixedly mounted on the top of the slide block 4. A screw 14 is rotatably mounted inside the support frame 13, and two clamping blocks 15 are threaded on the screw 14. The outer side of the clamping blocks 15 has a rough surface to increase the frictional resistance when clamping the annular part. The screw 14 has symmetrically distributed positive and negative threads. The two clamping blocks 15 are symmetrically mounted on the screw 14. When the screw 14 rotates, the positive and negative threads can drive the two clamping blocks 15 to move in the same direction or in opposite directions, clamping the annular part in the center, which is convenient for welding positioning of the welding torch 3. The clamping blocks 15 are slidably connected to the support frame 13. An auxiliary motor 16 is fixedly mounted on the top of the support frame 13, and the output end of the auxiliary motor 16 is fixed to the top of the screw 14.

[0039] To enable clamping and welding of ring-shaped parts of different sizes, the embodiments of this application are described below:

[0040] First, the drive motor 9 operates to drive the first bevel gear 11 to rotate. Through the meshing of the first bevel gear 11 and the second bevel gear 12, all the lead screws 6 rotate synchronously, thereby driving all the slide blocks 4 to move outward until the clamping block 15 is moved to the annular part.

[0041] Then, the auxiliary motor 16 is started to drive the screw 14 to rotate. The positive and negative threads of the screw 14 drive the two clamping blocks 15 to move in the same direction to clamp the ring part. Finally, the clamped part is located in the center of the screw 14.

[0042] Finally, the welding torch 3 is moved to the welding position by the hydraulic cylinder 18 and the electric push rod 17, the welding torch 3 is started, and the turntable 2 is started by the external controller. The turntable 2 drives the ring part to rotate, and multiple welding torches 3 are used to weld the part.

[0043] When it is necessary to clamp and weld larger ring-shaped parts, simply adjust the position of the slider on the base 1, move the clamping block 15 to the outside of the ring-shaped part, and use the clamping block 15 to stably clamp and fix the ring-shaped part before using the welding gun 3 to perform subsequent welding operations.

[0044] In some embodiments of this technical solution, such as Figure 1 As shown, in order to improve welding efficiency, multiple welding torches 3 are provided and evenly distributed on the outside of the turntable 2. Multiple welding torches 3 can weld ring parts at the same time, resulting in higher welding efficiency.

[0045] In some embodiments of this technical solution, such as Figure 4 and Figure 5 As shown, in order to prevent the screw 14 from directly contacting the part and scratching it when the clamping block 15 clamps the part, a limiting rod 19 is fixedly installed inside the support frame 13. The limiting rod 19 passes through the clamping block 15 and is slidably connected to the clamping block 15. By the limiting rod 19 pressing against the inside of the part, the part can be effectively prevented from contacting the screw 14.

[0046] In some embodiments of this technical solution, such as Figure 1 and Figure 2 As shown, in order to prevent the waste generated during welding from falling into the slot 5, the top of the slot 5 is provided with stretchable folding plates 20 symmetrically distributed on both sides of the slide block 4. One end of the stretchable folding plate 20 is fixed to the slide block 4, and the other end is fixed to the fixing plate provided on the top of the turntable 2. When the slide block 4 slides, it pulls and squeezes the stretchable folding plate 20 to ensure that the stretchable folding plate 20 always covers the slot 5, thereby preventing the waste generated during welding from falling into the slot 5.

[0047] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the principles, the implementation of the present invention may have any modifications or variations.
