Description

Technical Field

[0001] This utility model relates to the technical field of welding support devices, and in particular to a multi-segment welding support device. Background Technology

[0002] Welding support devices are essential equipment in industrial production to ensure the smooth progress of welding operations. They are used in various construction and manufacturing fields, and their function is to provide stable support and precise positioning for welded workpieces. The quality of welding support devices directly affects welding quality, production efficiency, and operator safety. With the trend of pursuing lightweight welding processes, roller-type welding supports have become the preferred equipment for enterprises due to their ease of movement and flexible operation.

[0003] Early welding support devices used fixed brackets or simple roller structures, whose support position and height were not adjustable, and were only suitable for weldments of specific sizes. To solve this problem, existing technology uses multi-segment adjustable roller brackets, which achieve flexible adjustment of roller spacing and height through telescopic support arms and quick locking mechanisms, thereby adapting to changes in weldment size. However, existing roller-type welding brackets still have the drawback of insufficient adaptability to weldments of different specifications. Due to the large differences in the diameter, length, or weight of weldments, the manual adjustment process is cumbersome and difficult to achieve fast and accurate positioning. At the same time, manual adjustment is prone to errors, and there is a risk of the weldment shifting position during rotation. How to prevent the weldment from shifting position on the welding device and ensure that it is welded accurately and efficiently remains a key problem that needs to be solved. Utility Model Content

[0031] 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.

[0032] Reference Figure 1 , Figure 3 and Figure 5This utility model provides an embodiment of a multi-segment welding support device, comprising two base plates 1. Grooves 3 are provided on the top left and right sides of both base plates 1 to provide sliding tracks for subsequent components. Sliding sliders 4 are slidably connected to the outer walls of multiple grooves 3 to adjust the position of a U-shaped bracket 5. A U-shaped bracket 5 is fixedly connected to the top of the sliders 4. A rod-mounted arc-shaped bracket 6 is rotatably connected to the inner wall of the U-shaped bracket 5 for supporting and connecting other components. Rod-mounted rollers 7 are rotatably connected to the upper and lower sides of the inner wall of the rod-mounted arc-shaped bracket 6, allowing rotation around the inner wall of the U-shaped bracket 5 to adjust the angle. Rotating rods 9 are fixedly connected to adjacent sides of the two rod-mounted rollers 7 on the top left side for connecting and transmitting power. A motor 8 is fixedly connected to the front side of the U-shaped bracket 5 on the front left side, serving as a power source to provide rotational power. The output end of the motor 8 passes through the U-shaped bracket. Gears 10 are fixedly connected to the inner walls of the frame 5 and the rod-mounted arc-shaped support 6 to transmit the power of the motor 8. Toothed belts 11 are provided on the outer walls of the upper and lower left rod rollers 7 to transmit power and achieve synchronous rotation. The outer wall of the toothed belt 11 on the front left side meshes with the outer wall of the gear 10 to transmit the power of the motor 8 to the rod rollers 7. Sleeves 12 are fixedly connected to adjacent sides of the left and right U-shaped supports 5 to connect and support straight rods 13. Straight rods 13 are slidably connected to the inner walls of the two sleeves 12. Straight rods 13 can slide on the inner walls of the sleeves 12 to adjust their length. Fixing components are provided on the outer walls of the sleeves 12 to fix the position of the sleeves 12 and ensure the stability of the device. Adjustment mechanisms 2 are provided on adjacent sides of the two base plates 1 to adjust the position of the welding device, which is suitable for welding steel pipes of different sizes.

[0033] Specifically, when the workpiece is placed above the roller, the rod-mounted arc-shaped support 6 rotates to fit against the outer contour of the workpiece. When the workpiece rotates to a certain angle, the downward pressure of the workpiece is transmitted downward through the rod-mounted arc-shaped support 6 and then through the U-shaped support to the slider 4, transforming it into a left-right sliding thrust. This structure prevents excessive deflection of the rod-mounted arc-shaped support 6, avoiding positional displacement due to unstable workpiece support. The movement of the slider 4 simultaneously drives the movement of the sleeve 12 fixedly connected to the U-shaped support. The interaction between the sleeve 12 and the straight rod 13 ensures the stability and safety of the slider 4 during movement. After the workpiece is stably placed, the start... Motor 8 drives gear 10 to rotate, which in turn rotates toothed belt 11 that meshes with it. Toothed belt 11 drives the upper and lower rollers on the left front side to rotate. At the same time, a rotating rod 9 is connected to the rear side of the upper roller. The rotation of the roller drives the rotating rod 9 to rotate, which in turn transmits power to the upper roller on the left rear side. The rotation of the roller drives the toothed belt 11 on its outer wall to rotate, which in turn causes the lower roller on the left rear side to rotate synchronously, thus achieving synchronous rotation of all rollers on the left side. When the workpiece is placed on the rollers, the left roller drives it to rotate, which in turn causes the right roller to rotate synchronously, thereby preventing the position of the workpiece from shifting.

[0034] Reference Figure 2 and Figure 4 The adjustment mechanism 2 includes a base 201, which is located on one side of two adjacent base plates 1, providing a support platform for the upper structure of the entire welding device.

The connecting wire 205 is threadedly connected to the top of the interface 204, used to transmit the electrical energy converted by the transformer 203 to the welding gun 206. The other end of the connecting wire 205 is fixedly connected to... The welding gun 206 is used to generate an electric arc and perform welding operations. A welding head 207 is fixedly connected to the left side of the welding gun 206. The welding head 207 directly contacts the welding part, converting electrical energy into heat energy to melt the welding rod and achieve welding. Electric telescopic columns 208 are fixedly connected to the front and rear sides of the top of the base 201. The electric telescopic columns 208 can be extended and retracted as needed to adjust the height position of the welding gun 206. Support rods 209 are fixedly connected to adjacent sides of the two electric telescopic columns 208. The support rods 209 are used to support and fix the fixing rings 210. Fixing rings 210 are fixedly connected to adjacent sides of the two support rods 209 to fix the welding gun 206 and prevent it from shaking or shifting during the welding process. The inner wall of the fixing rings 210 is engaged with the outer wall of the welding gun 206.

[0035] Specifically, a transformer 203 is installed above the base 201, which is connected to a connecting line 205 via an interface 204 to provide power to the welding gun 206. Finally, welding of the workpiece is achieved through the welding head 207. At the same time, electric telescopic columns 208 are fixedly connected to the front and rear sides of the base 201. The support rods 209 connected to the adjacent sides of the two electric telescopic columns 208 provide support for the fixing ring 210, so that the welding gun 206, which is engaged with the inner wall of the fixing ring 210, can move up and down under the action of the electric telescopic rod 23. In addition, multiple wheels 202 are provided at the bottom of the base 201 to facilitate the movement of the adjustment mechanism 2.

A limit block 19 is provided on the outside to prevent the toothed belt 11 from shifting or falling off during operation, ensuring the normal transmission of the toothed belt 11. Multiple spherical columns 20 are fixedly connected to the outer walls of multiple rod rollers 7 to increase the friction between the rod rollers 7 and the contacting object, improve transmission efficiency, and reduce damage to the surface of the contacting object. A magnetic ring 21 is fixedly connected to the outer wall of the welding gun 206 to fix the welding gun 206 to the inner wall of the fixing ring 210, preventing the welding gun 206 from falling off during use.

[0037] Specifically, the lower semi-circular ring 15 is supported to a suitable height position by the support column 14, providing a foundation for fixing other components. The ring structure can be easily opened and closed by the rotational connection between the lower semi-circular ring 15 and the upper semi-circular ring 16. The upper semi-circular ring 16 and the lower semi-circular ring 15 are fixedly connected by the snap fastener 17. The axial movement range of other components on the rotating rod 9 is limited by the limiting ring 18. The limiting block 19 is used to prevent the toothed belt 11 from shifting or falling off during operation, ensuring the normal transmission of the toothed belt 11. The spherical column 20 increases the friction between the belt rod roller 7 and the contacting object, improving transmission efficiency and reducing damage to the surface of the contacting object. The magnetic ring 21 fixes the welding gun 206 to the inner wall of the fixing ring 210, enhancing the connection between the two and preventing the welding gun 206 from falling off during use.

The electric telescopic rod 23 is fixedly connected to the front and rear sides of the outer wall of the connecting column 22, and it moves in extension and retraction by electric drive. The outer wall of the electric telescopic rod 23 engages with the inner wall of the wheel 202, thereby restricting the movement of the wheel 202. The top of the two electric telescopic columns 208 is fixedly connected to the lamp holder 24, providing a structure for the installation and support of the LED lamp 25. The top of the lamp holder 24 is fixedly connected to the LED lamp 25 to illuminate the welding area. A display screen 26 is provided on the right inner wall of the transformer 203 to display the working status and related parameters of the transformer 203. A control button 27 is fixedly connected to the lower right side of the transformer 203 to control the opening and closing of the transformer 203.

[0039] Specifically, the base 201 is connected to the electric telescopic rod 23 below via the connecting column 22, which supports the electric telescopic rod 23. The electric telescopic rod 23 is electrically driven to extend and retract. The outer wall of the electric telescopic rod 23 engages with the inner wall of the wheel 202, thereby restricting the movement of the wheel 202. The lamp holder 24 provides a structure for mounting and supporting the LED light 25. The LED light 25 illuminates the welding area, allowing the operator to observe the welding parts more clearly and improving the accuracy and quality of the welding. The working status and related parameters of the transformer 203 can be observed through the display screen 26. The transformer 203 can be turned on and off through the control button 27.

[0040] Working principle: When the workpiece is placed above the roller, the rod-mounted arc-shaped support 6 rotates to fit against the outer contour of the workpiece. When the workpiece rotates to a certain angle, the downward pressure of the workpiece is transmitted downward through the rod-mounted arc-shaped support 6 and then through the U-shaped support to the slider 4, which is converted into a left-right sliding thrust. This structure prevents excessive deflection of the rod-mounted arc-shaped support 6, avoiding positional displacement due to unstable workpiece support. The movement of the slider 4 simultaneously drives the sleeve 12, which is fixedly connected to the U-shaped support, to move. The interaction between the sleeve 12 and the straight rod 13 ensures the stability and safety of the slider 4 during movement. After the workpiece is stably placed... The motor 8 is started, which drives the gear 10 to rotate, thereby causing the toothed belt 11 that meshes with it to rotate. The toothed belt 11 drives the upper and lower rollers on the left front side to rotate. At the same time, the upper roller is connected to the rear side of the rotating rod 9. The roller rotates, which in turn drives the rotating rod 9 to rotate, and at the same time transmits power to the upper roller on the left rear side. The rotation of the roller drives the toothed belt 11 on its outer wall to rotate, thereby causing the lower roller on the left rear side to rotate synchronously, realizing the synchronous rotation of all rollers on the left side. When the workpiece is placed on the rollers, the left roller drives it to rotate, thereby causing the right roller to rotate synchronously, thus preventing the position of the workpiece from shifting.

[0041] Furthermore, the base 201 is connected to the electric telescopic column 208. A transformer 203 is installed on the top of the base 201, and a connecting line 205 is connected through the interface 204 to provide power to the welding gun 206. Finally, the welding head 207 is used to weld the workpiece. At the same time, the electric telescopic column 208 is fixedly connected to the front and rear sides of the top of the base 201. The support rod 209 connected to the adjacent side of the two electric telescopic columns 208 provides support for the fixing ring 210, so that the welding gun 206, which is engaged with the inner wall of the fixing ring 210, can move up and down under the action of the electric telescopic rod 23. In addition, multiple wheels 202 are provided at the bottom of the base 201 to facilitate the movement of the adjustment mechanism 2. This structure facilitates the movement of the welding device and meets the welding accuracy requirements for workpieces of different sizes.
