Technical Field
[0001] The utility model relates to the technical field of welding equipment, in particular to an adaptive anti-slip roller frame. Background Art
[0002] The roller frame is a displacement device that uses the friction between the roller and the workpiece to drive the workpiece to rotate. It is widely used in the assembly and welding of various cylindrical workpieces such as pipes, containers, boilers, and oil tanks. At present, large cylindrical workpieces are mostly connected by girth welding. If the position of the workpiece is always fixed, welding on the top of the workpiece will be very difficult. The existing solution is to place the workpiece on the roller frame, and drive the workpiece to rotate through the rotation of the roller frame, so that the welding part is always located at the bottom of the workpiece, avoiding vertical welding and overhead welding, and reducing the difficulty of operation. However, different workpieces have different diameters. When using the roller frame, it is necessary to manually adjust the roller spacing to match the different workpiece diameters. When there are many types of products, manual adjustment is too frequent and inefficient. Summary of the invention

[0006] Furthermore, the rotating support frame is located between the two side plates, the second cylinder passes through the side wall of the rotating support frame and is rotatably connected to the two side plates, the cylinder end of the cylinder is hinged to the supporting bracket, and the end of the piston rod of the cylinder is hinged to the third cylinder.
[0007] Furthermore, the rotating support frame is a frame body symmetrical about the second cylinder, and the rotating support wheels are two and are arranged symmetrically about the second cylinder on the rotating support frame.

Driven by the oil cylinder, the rotating support wheel can adapt to many workpieces of different diameters. At the same time, the oil cylinder control is used instead of manual adjustment, which improves efficiency and ensures accuracy. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0023] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments:
[0024] like Figures 1 to 9 As shown, this embodiment provides an adaptive anti-slip roller frame, including an active roller frame 1, a driven roller frame 2 and a power mechanism, and the active roller frame 1 and the driven roller frame 2 are each provided with two symmetrically arranged supporting mechanisms, and the supporting mechanisms include a supporting bracket 3, a bogie and a rotating supporting frame 4.
[0025] The supporting bracket 3 is fixedly connected to the active roller frame 1 and the driven roller frame 2. The bogie is located in the supporting bracket 3. One end of the bogie is rotatably connected to the supporting bracket 3 and the other end is connected to the cylinder 5. The cylinder barrel of the cylinder 5 is hinged to the supporting bracket 3, and the piston rod of the cylinder 5 is hinged to the bogie.
[0026] like Figure 1 to Figure 4 As shown, in this embodiment, the support bracket 3 is fixed to the two ends of the active roller frame 1 and the driven roller frame 2 by bolts, and a bracket is provided on the side away from the two support brackets 3, and a cylinder 5 is arranged in the bracket to avoid interference with the movement of the bogie and the rotating support frame 4.
[0027] The bogie is provided with a rotating support frame 4, which is located above the oil cylinder 5 and is rotatably connected to the bogie. The rotating support frame 4 is rotatably connected to a rotating support wheel 6, and the power mechanism drives the rotating support wheel 6 to rotate. The rotating support frame 4 is a frame body symmetrical about the second cylinder 12, such as Figure 6 As shown, the rotating support wheel 6 is symmetrically arranged on the rotating support frame 4 about the second cylinder 12. There are two rotating support wheels 6 and they are symmetrically arranged on the rotating support frame 4 about the second cylinder 12. The power mechanism includes a motor 15 and a reducer 16. The output end of the motor 15 is connected to the input end of the reducer 16, and the output end of the reducer 16 drives the rotating support wheel 6 to rotate.
[0028] like Figure 1 and Figure 2 As shown, in order to save costs, in this embodiment, a power mechanism is only provided on the active roller frame 1, but in another possible implementation mode, a power mechanism can be provided on both the active roller frame 1 and the driven roller frame 2 to drive the rotating support wheel 6 to rotate synchronously to realize the rotation of the workpiece.
[0029] In this embodiment, as a preference, the reducer 16 is fixed on one side of the rotating support frame 4 .
[0030] As an implementable embodiment, the bogie includes two symmetrically arranged side plates 10 and a first cylinder 11, a second cylinder 12, and a third cylinder 13 arranged between the two side plates 10, the first cylinder 11 is located on the side where the two supporting brackets 3 are close to each other and the first cylinder 11 is rotatably connected to the supporting bracket 3 through the side plate 10, the second cylinder 12 and the third cylinder 13 are located on the side where the two supporting brackets 3 are away from each other and the third cylinder 13 is located below the second cylinder 12, the second cylinder 12 is rotatably connected to the two side plates 10, the third cylinder 13 is fixedly connected to the two side plates 10, the rotating support frame 4 is located between the two side plates 10, the second cylinder 12 is rotatably connected to the two side plates 10 through the side wall of the rotating support frame 4, the cylinder end of the oil cylinder 5 is hinged to the supporting bracket 3, and the end of the piston rod of the oil cylinder 5 is hinged to the third cylinder 13.
[0031] like Figure 3 As shown, in this embodiment, the first cylinder 11 is fixedly connected to the side plate 10. When the first cylinder 11 rotates, it drives the side plate 10 to rotate, thereby driving the bogie to rotate. When the piston rod of the oil cylinder 5 is extended, it drives the second cylinder 12 and the third cylinder 13 on the bogie to move toward the direction close to the workpiece. At this time, the bogie rotates counterclockwise, and the rotating support wheel 6 on the rotating support frame 4 gradually approaches the workpiece. In the process of tightening the workpiece, the rotating support frame 4 will rotate relative to the second cylinder 12 because it adapts to the outside of the workpiece, and the rotating support wheel 6 finally abuts against the workpiece.
[0032] In this embodiment, the rotating support wheel 6 is made of a rubber wheel material to increase the friction with the workpiece and prevent the workpiece from slipping when rotating.
[0033] As an implementation method, the two rotating support wheels 6 are rotated by two power mechanisms, and the two power mechanisms are provided with torque arms 18, and the two torque arms 18 are fixedly connected on the sides close to each other. The head of the torque arm 18 is the side with a smaller diameter, such as Figure 8 As shown, in this embodiment, two shaft holes are provided at the head of the torque arm 18, and pins are passed through the shaft holes on the two torque arms 18 to achieve fixation, thereby ensuring the stability of the power mechanism.
[0034] As an implementation method, Figure 7 As shown, the lower parts of the active roller frame 1 and the driven roller frame 2 are both provided with pulleys 14 that cooperate with the external track.
[0035] As an implementation method, a baffle 19 is fixed between the two side plates 10. The baffle 19 is located on one side of the rotating support wheel 6 to prevent the rotating support wheel 6 from interfering with other components when rotating.
[0036] In the initial state of the utility model, the piston rod of the oil cylinder 5 is in a retracted state, at this time the bogie is completely in the supporting bracket 3, and the rotating support wheel 6 is in a horizontal state. During operation, the piston rod of the oil cylinder 5 is lifted, and the third cylinder 13 hinged to the piston rod drives the bogie to rotate counterclockwise. At this time, the second cylinder 12 and the third cylinder 13 move in the direction of approaching the workpiece. In the process of the rotating support frame 4 approaching the workpiece, the contact between the rotating support wheel 6 and the workpiece causes the rotating support frame 4 to rotate relatively on the second cylinder 12, so that the rotating support wheel 6 adapts to the size of the workpiece. After the workpiece is tightened, the power mechanism on the pulley 14 matched with the external track drives the pulley 14 to move, and brings the workpiece to the welding location. At this time, the power mechanism on the active roller frame 1 starts to work, driving the workpiece to rotate, thereby assisting the workpiece in ring welding.
[0037] The embodiments described above are only preferred embodiments of the present invention and are not intended to limit the scope of implementation of the present invention. Therefore, any equivalent changes or modifications made based on the structures, features and principles described in the patent scope of the present invention should be included in the patent application scope of the present invention.
