[0026] The present invention will be further described in detail below with reference to the accompanying drawings.

[0027] Identical parts are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific part, respectively.

[0028] like Figures 1 to 5 As shown, a chain-type turning machine adaptable to various workpieces includes four turning components. A crossbeam 1 is bolted to each turning component on the same side and is driven by a turning chain 2. The bottom of the turning chain 2 passes through the interior of the crossbeam 1. Each turning component includes a base 3, on which a column 4 is bolted. The column 4 is rotatably connected to a turning arm 6 via a first turning shaft 5. The first turning shaft 5 is driven by the turning chain 2 and is equipped with a drive component. A second turning shaft 7 is provided at one end of the turning arm 6 and is driven by the turning chain 2. A chain straightening component is provided at the top of the turning arm 6. A roller assembly for adapting to the shape of the material is provided on the crossbeam 1.

[0029] The equipment is mainly used for flipping, welding, and grinding of square, rectangular, and round tubes of different specifications, making the welded and ground surfaces more visible. The equipment is suitable for square, rectangular, round, and polygonal products that are welded together. After the products are firmly spot-welded, they can be placed on this equipment to complete the full welding operation, and grinding operations can also be completed. In use, the two flipping components on the same side are connected by the crossbeam 1, and the material is placed on the two flipping chains 2. The base 3 provides support for the entire flipping component. The drive component acts as the drive source, driving the first flipping shaft 5 to rotate accordingly. Since the first flipping shaft 5 and the second flipping shaft 7 are both connected to the flipping chain 2, the flipping chain 2 can rotate accordingly. The drive components on the four flipping components rotate in the same direction to flip the material. The drive components on the four flipping components rotate in opposite directions to retract and extend the flipping chain 2, which can change the height of the material from the ground. By using the chain straightening component, the flipping arm 6 can be rotated accordingly, so that the material can be better clamped. The roller component can provide a clamping point or contact point for the two ends of the material.

[0030] like Figures 2 to 4 As shown, a first reversing gear 8 is provided on the first reversing shaft 5, and the first reversing gear 8 meshes with the reversing chain 2; the driving assembly includes a driving chain 9, with a driving sprocket 10 and a driven sprocket 11 respectively wound around both ends of the driving chain 9; a driving motor 12 is provided on the driving sprocket 10, and the output shaft of the driving motor 12 passes through the column 4 and is drivenly connected to the inner wall of the driving sprocket 10 and the column 4; the driving motor 12 is located on one side of the column 4; and the driven sprocket 11 is drivenly connected to the first reversing shaft 5; a second reversing gear 13 is drivenly connected to the second reversing shaft 7, and the second reversing gear 13 meshes with the reversing chain 2.

[0031] The drive motor 12 serves as the drive source, and its output shaft can drive the drive sprocket 10 to rotate accordingly. The rotation of the drive sprocket 10 can drive the drive chain 9 and the driven sprocket 11 to rotate accordingly. The rotation of the driven sprocket 11 can drive the first rotating gear 8 to rotate accordingly through the first rotating shaft 5. The first rotating gear 8 meshes with the rotating chain 2. The rotation of the first rotating gear 8 and the second rotating gear 13 can cause the rotating chain 2 to rotate accordingly, so that the rotating chain 2 can rotate the material or change its height from the ground.

[0032] like Figure 3As shown, the chain straightening assembly includes a movable pulley 14 and a counterweight 15. The movable pulley 14 is bolted to the top of the tilting arm 6 via a pulley base plate 16. A pulley rope 17 is slidably connected to the movable pulley 14. One end of the pulley rope 17 is fixed with a first fixing ring 18, which is located on the top of the column 4. The other end of the pulley rope 17 is fixed with a second fixing ring 19, which is located on the top of the counterweight 15. The pulley rope 17 is also slidably connected to a fixed pulley 20, which is bolted to one side of the column 4 via a pulley side plate 21.

[0033] The counterweight 15 hangs naturally under gravity, and the downward pull it generates is transmitted through the pulley rope 17, causing a corresponding displacement. During this process, the fixed pulley 20 is bolted to one side of the column 4 via the pulley side plate 21, serving as a guide to ensure that the pulley rope 17 moves stably along the preset path. Through the synergistic action of the first fixed ring 18 and the second fixed ring 19, the pulley rope 17 forms a stable mechanical connection between the counterweight 15 and the column 4. When the counterweight 15 is displaced, its tension is transmitted through the pulley rope 17 to the movable pulley 14, which is bolted to the top of the tilting arm 6 via the pulley base plate 16, thereby driving the tilting arm 6 to rotate around its axis. This structural design, through the torque amplification effect of the pulley system, makes the rotation of the tilting arm 6 more effortless and controllable, thereby optimizing the stability and efficiency of the material clamping process.

[0034] like Figure 5 As shown, the roller assembly includes two sliding rollers 22, each fixed to a slider 23 via a roller base. Displacement adjustment components are mounted on the two sliders 23, and slide rails 26 are slidably connected to the bottom of each slider 23, with the slide rails 26 positioned on the upper surface of the crossbeam 1. The displacement adjustment components include an adjusting screw 24 and an adjusting motor 25. The adjusting screw 24 passes through and is threadedly connected to the two sliders 23. One end of the adjusting screw 24 is driven by an adjusting driven wheel 31. An adjusting driving wheel 32 is driven by the output shaft of the adjusting motor 25. The adjusting motor 25 is fixed to the bottom of the crossbeam 1 via adjusting mounting plate bolts. The displacement adjustment assembly also includes an adjusting belt 33, with its two ends wound around the adjusting driving wheel 32 and the adjusting driven wheel 31, respectively.

[0035] The adjusting screw 24 is a bidirectional screw with opposite threads at both ends, allowing the two sliders 23 to move synchronously towards or away from each other. One side of the adjusting belt 33 passes through the crossbeam 1 and drives the adjusting drive wheel 32 to rotate via the adjusting motor 25. The rotation of the adjusting drive wheel 32 drives the adjusting belt 33 and the adjusting driven wheel 31 to rotate, causing the adjusting screw 24 to rotate accordingly, thus displacing the sliders 23 on the slide rail 26. The two sliders 23 move away from or closer to each other, causing the sliding rollers 22 on the sliders 23 to move away from or closer to each other. This can accommodate materials of different widths. The sliding rollers 22 are V-shaped rollers, which are particularly suitable for square and rectangular tubes. The two inclined surfaces naturally hold the corners, providing stable support and turning torque. For round tubes, they can also provide two contact points.

[0036] like Figure 5 As shown, a position control switch 27 is provided on one side of the crossbeam 1. The position control switch 27 is fixed to the crossbeam 1 by bolts through the switch mounting plate 28. A control hole 29 is provided on one side of the crossbeam 1. The push rod 30 of the position control switch 27 passes through the control hole 29. The bottom of the flipping chain 2 passes through the inside of the crossbeam 1. The push rod 30 of the position control switch 27 extends into the inside of the crossbeam 1. The position of the flipping chain 2 can be controlled accordingly by the push rod 30 of the position control switch 27, so that the chain can clamp the material more effectively.

[0037] Working Principle: During the material flipping operation, the material is first placed on two flipping chains 2. The drive motor 12 serves as the power source. After starting, its output shaft rotates, driving the drive sprocket 10 to rotate. The rotation of the drive sprocket 10 is transmitted to the driven sprocket 11 via the drive chain 9, causing the driven sprocket 11 to rotate as well. The rotation of the driven sprocket 11 then drives the first flipping gear 8 to rotate via the first flipping shaft 5. The second flipping gear 13 meshes with the flipping chain 2, and the rotation of the first flipping gear 8 and the second flipping gear 13 together drive the flipping chain 2. When the four drive motors 12 rotate in the same direction, the flipping chain 2 works in tandem, thus flipping the material. When the four drive motors 12 rotate in opposite directions, the flipping chain 2 retracts or extends, changing the height of the material above the ground. To ensure that the flipping chain 2 can accurately and effectively clamp the material, the system is equipped with a position control switch 27. By operating the push rod 30 of the position control switch 27, the position of the tilting chain 2 can be precisely adjusted to better conform to the material and achieve a more effective clamping effect. During the clamping process, the counterweight 15 hangs naturally under its own weight, and the downward pull it generates is transmitted through the pulley rope 17. The fixed pulley 20 in the pulley system is firmly fixed to one side of the column 4 by bolts through the pulley side plate 21, playing a key guiding role and ensuring that the pulley rope 17 can move stably along the preset path. When the counterweight 15 is displaced, its pull is transmitted to the movable pulley 14 through the pulley rope 17, and the movable pulley 14 is fixed to the top of the tilting arm 6 by bolts through the pulley base plate 16. The pull causes the movable pulley 14 to drive the tilting arm 6 to rotate around the axis, further enhancing the clamping effect on the material; however, there are certain limitations when the tilting chain 2 directly contacts the workpiece. For round or irregularly shaped tubes, the material is prone to slipping during the flipping process due to unstable contact points. For square or rectangular tubes, the flipping chain 2 may not fit their edges well, resulting in poor clamping effect. By adjusting the motor 25 to drive the adjusting drive wheel 32 to rotate, the rotation of the adjusting drive wheel 32 can drive the adjusting belt 33 and the adjusting driven wheel 31 to rotate, and the adjusting screw 24 to rotate accordingly, so that the slider 23 can move accordingly on the slide rail 26, thereby causing the sliding rollers 22 on the slider 23 to move away from or closer to each other, so as to adapt to materials of different widths. The two inclined surfaces of the rollers can naturally hold the edges or provide two contact points.

After reading this specification, those skilled in the art can make modifications to these embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this utility model.
