[0002] Welding, a common manufacturing technique, joins workpieces by heating them to a molten state. During welding, cylindrical workpieces are difficult to hold steady and typically require tools to ensure stability and quality. Therefore, various welding roller frames have emerged on the market, enabling stable support and rotation of cylindrical workpieces to meet welding requirements at different angles.
[0003] While existing welding roller frames can support and rotate workpieces, the use of multiple welding frames for this purpose necessitates manual adjustment of the distance between the welding frames or replacement with welding roller frames of different sizes when the workpiece length or dimensions change. This also requires readjusting the positioning reference, reducing work efficiency and increasing operational complexity and time costs. Therefore, this invention proposes an adjustable welding roller frame. Summary of the Invention

Detailed Implementation
[0022] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.
[0023] In this embodiment, refer to Figures 1-5 The adjustable welding roller frame, specifically implemented therein, includes a base 1 and a support plate 2. The base 1 has a first boss 11 and a second boss 12. The support plate 2 is slidably mounted on the first boss 11 via a screw-slider assembly 3. One end of the base 1 is provided with a drive motor 4 connected to the screw-slider assembly 3. Main wheel sets 5 are symmetrically arranged on both sides of the second boss 12. Sub-wheel sets 6 that cooperate with the main wheel sets 5 are symmetrically arranged on the support plate 2. Both the main wheel sets 5 and the sub-wheel sets 6 include a mounting frame 51, a swing frame 52, and several rolling wheels 53. The mounting frame 51 is provided with a rotating shaft 54. The swing frame 52 is sleeved on the outside of the rotating shaft 54. Several rolling wheels 53 are rotatably mounted on both ends of the swing frame 52. One side of the mounting frame 51 is provided with a drive component 7 that connects and cooperates with the rolling wheels 53. The rotating shaft 54 and the rolling wheels 53 are rotatably mounted on the mounting frame 51 and the swing frame 52 respectively via bearings. The swing frame 52 is provided with a bearing rod that cooperates with the rolling wheels 53. This allows the rolling wheel 53 to rotate smoothly under the drive of the drive component 7, thereby driving the workpiece placed on the roller frame to perform welding operations. During installation, the first boss 11 and the second boss 12 serve as installation reference surfaces, ensuring the installation accuracy of the main wheel assembly 5 and the auxiliary wheel assembly 6 while reducing the machining range, thus lowering manufacturing costs.
[0024] The lead screw and slider assembly 3 includes a lead screw 31 and several sliding blocks 32. Both ends of the lead screw 31 are provided with bearing seats 33, and the lead screw 31 is rotatably mounted on the bearing seats 33 via bearings. The bearing seats 33 are fixedly mounted on the base 1. The support plate 2 is provided with a nut seat 34 that mates with the lead screw 31. Several sliding blocks 32 are symmetrically arranged on both sides of the support plate 2. Both sides of the base 1 are provided with linear guides 35 that mate with the sliding blocks 32. One end of the lead screw 31 is connected to the drive motor 4. Limit blocks are provided on both sides of the lead screw 31, which can provide a hard limit, ensuring that the support plate 2 will not move out of the range of the lead screw 31 during movement, thereby ensuring the safety and stability of the entire device.
[0025] In use, the screw 31 is rotated by the drive motor 4, which drives the support plate 2 to slide together through the nut seat 34. The sliding blocks 32 on both sides of the support plate 2 cooperate with the linear guide 35, so that the support plate 2 can slide smoothly. This allows the parallelism and coaxiality between the main wheel group 5 and the auxiliary wheel group 6 to be maintained while adjusting the spacing, thus ensuring the stability and accuracy of the welding roller frame.
[0026] In addition, both sides of the first boss 11 are provided with limiting flanges 111 that cooperate with the linear guide 35. Both sides of the first boss 11 are provided with fixing grooves 112, and several pressure blocks 113 that cooperate with the limiting flanges 111 are provided within the fixing grooves 112. The pressure blocks 113 are linearly distributed along the length of the fixing grooves 112. The limiting flanges 111 can serve as a connection reference between the linear guides 35, further improving the installation accuracy of the linear guides 35. This makes installation more convenient and faster. The pressure blocks 113 are respectively bolted to the fixing grooves 112, thereby cooperating with the limiting flanges 111 to apply a certain pressure to the linear guide 35, enhancing the load-bearing capacity of the linear guide 35, ensuring that the linear guide 35 will not deviate or shake during use, and further improving the stability and accuracy of the entire device.
[0027] Meanwhile, the second boss 12 and the support plate 2 are respectively provided with support blocks 8 that cooperate with the swing frame 52. The support blocks 8 can prevent the rolling wheel 53 from contacting the second boss 12 or the support plate 2, thereby protecting the rolling wheel 53 from damage and ensuring the stability of the rolling wheel 53 during rotation. In addition, the support blocks 8 also have a certain adjustment function. The height of the support blocks 8 can be adjusted by adding shims or other means as needed, thereby reducing the range of motion of the swing frame 52.
[0028] The driving component 7 and the rolling wheel 53 are connected by a pulley 9 or a gear. Through the transmission of the pulley 9 or gear, the driving component 7 can stably and efficiently transmit power to the rolling wheel 53, ensuring that the rotational speed and driving force of the rolling wheel 53 meet the requirements of the welding operation. The selection of the pulley 9 or gear depends on the actual working conditions and requirements. For example, when a larger transmission ratio or lower welding precision is required, gear transmission can be selected; while when higher welding precision is required, pulley 9 transmission can be selected to reduce vibration and noise and improve welding quality. In this embodiment, pulley 9 transmission is used. The pulleys 9 are respectively mounted on the bearing rod and the rotating shaft 54. The driving component 7 is fixedly connected to the rotating shaft 54 through a coupling, and the pulleys 9 are connected by a belt, thereby achieving power transmission while ensuring the smoothness and precision of the rotation of the rolling wheel 53.
[0029] Furthermore, the lower end of the base 1 is equipped with several adjustable feet 10. These adjustable feet 10 allow for leveling of the base 1 according to the operating environment, ensuring the stability and levelness of the entire welding roller frame after installation. The adjustable feet 10 are typically designed with a threaded structure; by rotating the adjustable feet 10, the height of the base 1 can be easily adjusted, thus achieving leveling. This design not only improves the installation flexibility of the welding roller frame but also ensures good performance under various ground conditions. The use of adjustable feet 10 enables the welding roller frame to adapt to various complex working environments, improving its practicality and application range.
[0030] The beneficial effects of this utility model are as follows: Through the cooperation of the drive motor 4 and the lead screw and slider assembly 3, the support plate 2 slides, thereby adjusting the distance between the main wheel assembly 5 and the auxiliary wheel assembly 6 to accommodate cylindrical workpieces of different lengths. Furthermore, through the cooperation of the mounting bracket 51, the rotating shaft 54, and the swing frame 52, it can accommodate cylindrical workpieces of different diameters. Simultaneously, through the cooperation of the drive component 7 and the rolling wheel 53, the workpiece is rotated, thereby meeting the welding angle requirements.
