Description

Technical Field

[0001] The utility model relates to the technical field of welding, in particular to a welding roller frame. Background Art

[0002] The welding roller frame is a welding auxiliary equipment, which is often used for welding the inner and outer circumferential seams and the inner and outer longitudinal seams of cylindrical workpieces. It consists of a base, rollers, brackets, transmission devices and power device drives. The commonly used welding roller frame currently has a pair of rollers symmetrically arranged at the front and rear ends of the base, and the rollers are in contact with the outer wall of the cylinder of the cylindrical workpiece. During the welding process, the power device outputs power and drives the rollers to rotate through the transmission device, thereby improving the quality of the weld, reducing labor intensity, and improving welding efficiency. However, because the contact area between the roller and the outer wall of the cylinder is limited, the outer wall plate of the cylinder in contact with the roller is subjected to a large pressure, resulting in extrusion, causing the outer wall plate of the cylinder to be concave. Utility Model Content

[0003] In order to solve the problems and shortcomings existing in the prior art, the utility model provides a welding roller frame, which increases the number of roller assemblies of the welding roller frame and increases the contact area between the cylinder and the rollers on the roller assemblies, thereby increasing the force-bearing area of ​​the outer wall plate of the cylinder, reducing the pressure on the outer wall plate of the cylinder, and thereby improving the concave phenomenon of the outer wall plate of the cylinder.

[0004] Specifically, the utility model provides a welding roller frame, comprising:

[0005] A base, wherein the base is made of a rigid material;

[0006] A roller assembly, the roller assembly comprising a roller bracket and a roller rotatably mounted on the roller bracket; the roller assembly is horizontally symmetrically arranged at both ends of the base; each end of the base is provided with no less than two groups of the roller assemblies, so that when the cylinder to be welded is placed on the welding roller bracket, the rollers of at least two groups of the roller assemblies at each end of the base are in contact with the outer wall of the cylinder.

[0007] Optionally, two groups of roller assemblies are symmetrically arranged at each end of the base, and the four roller assemblies arranged on the base are completely consistent.

[0008] Optionally, the welding roller frame further includes a roller assembly support plate;

[0009] There are two roller assembly support plates, which are symmetrically arranged above the base, and the roller assembly is connected to the base via the roller assembly support plates.

[0010] Optionally, at least one of the roller assembly support plates can be moved along the length direction of the base to adjust the distance between two of the roller assembly support plates.

[0011] Optionally, the roller assembly and the roller assembly support plate are connected via an elastic member.

[0012] Optionally, the welding roller frame further includes a rolling device;

[0013] The rolling device is arranged below the base; the rolling device is connected to the base so that the rolling device drives the welding roller frame to move.

[0014] In the welding roller bracket of the utility model, each roller has a rotation axis, and the roller axes of the roller groups arranged at the same end of the base are on the same straight line. When the cylinder to be welded is placed horizontally on the roller frame, the outer wall of the cylinder contacts the roller assemblies at both ends of the base, and at least two rollers of the roller assemblies at each end of the base contact the outer wall of the cylinder. In other words, when the cylinder is placed horizontally on the roller frame, at least four rollers contact the outer wall of the cylinder. By increasing the number of roller assemblies arranged on the base, the number of rollers in contact with the outer wall of the cylinder is increased, and the contact area between the outer wall of the cylinder and the rollers is increased, which solves the problem that the outer wall plate of the cylinder is concave due to the small joint surface between the welding roller frame and the outer wall of the cylinder.

[0022] The welding roller frame is a welding auxiliary equipment, which is commonly used for welding the inner and outer circumferential seams and inner and outer longitudinal seams of cylindrical or conical workpieces. It includes a base, an active roller, a driven roller, a bracket, a transmission device, a power device drive and other components. The transmission device drives the active roller, and uses the friction between the active roller and the cylindrical workpiece to drive the workpiece to rotate and achieve displacement, which can realize the horizontal position welding of the inner and outer circumferential seams and the inner and outer longitudinal seams of the workpiece, which can greatly improve the quality of the weld, reduce labor intensity, and improve work efficiency.

[0023] Figure 1 Schematic diagram of the structure of a welding roller frame according to an embodiment of the utility model. Figure 1 As shown, combined with Figure 2 and Figure 3 The embodiment of the utility model provides a welding roller frame 100, including a base 110 and a roller assembly 120. The roller assembly 120 includes a roller bracket 122 and a roller 121 rotatably mounted on the roller bracket 122. The roller assemblies 120 are horizontally symmetrically arranged at both ends of the base 110, and each end of the base 110 is provided with no less than two groups of roller assemblies 120, so that when welding the cylinder, at least two rollers 121 of the roller assemblies 120 at each end of the base 110 are in contact with the outer wall of the cylinder.

[0024] In this embodiment, each roller 121 has a rotation axis, and the roller axes of the roller assemblies 120 arranged at the same end of the base 110 are on the same straight line. When the cylinder to be welded is placed horizontally on the welding roller frame 100, the outer wall of the cylinder contacts the roller assemblies 120 at both ends of the base 110, and at least two rollers 121 of the roller assemblies 120 at each end of the base 110 contact the outer wall of the cylinder. In other words, when the cylinder is placed horizontally on the welding roller frame 100, at least four rollers 121 contact the outer wall of the cylinder.

[0025] In this embodiment, by increasing the number of roller assemblies 120 provided on the base 110, the number of rollers 121 in contact with the outer wall of the cylinder is increased, the contact area between the outer wall of the cylinder and the rollers 121 is increased, and the problem of the outer wall plate of the cylinder being concave due to the small joint surface between the welding roller 100 and the outer wall of the cylinder is solved.

[0026] In some embodiments of the utility model, the roller 121 is a rubber roller 121. Rubber is a highly elastic polymer material with reversible deformation and is elastic at room temperature. When the rubber roller 121 is selected, when the cylinder is placed on the welding roller frame 100, the outer wall of the cylinder contacts the rubber roller 121 of the welding roller frame 100, and the rubber roller 121 is deformed under the gravity of the cylinder, thereby increasing the contact surface between the outer wall of the cylinder and the rubber roller 121, and reducing the pressure on the outer wall of the cylinder at the contact surface between the outer wall of the cylinder and the welding roller 121, thereby further avoiding the outer wall plate of the cylinder from being dented. In addition, since rubber has a relatively low hardness, it will not cause damage to the outer wall plate of the cylinder. Furthermore, since rubber has good elasticity, the rubber roller 121 can return to its original state after the cylinder is removed.

[0027] In other embodiments of the present invention, the roller 121 is a rigid material with a rubber outer surface. In this embodiment, the rigid material is selected as the inner core of the roller 121, which takes advantage of the rigid material's difficulty in deformation. The inner core of the roller 121 is made of a rigid material to avoid the roller 121 from being squeezed and deformed due to the cylinder pressure, so that the roller 121 can better maintain a cylindrical shape.

[0028] In this embodiment, a rigid material is selected as the inner core of the roller 121, so that the roller 121 is less deformed when subjected to the pressure of the cylinder, and the roller 121 maintains a cylindrical shape. The friction force that needs to be overcome when the cylinder rotates is small, and the rotation of the cylinder is simple and labor-saving.

[0029] like Figure 2As shown, in some embodiments of the present invention, two groups of roller assemblies 120 are symmetrically arranged at each end of the base 110. In this embodiment, the four roller assemblies 120 arranged on the base 110 are completely consistent, and the highest points of the four roller assemblies 120 are located in the same plane. When the cylinder is placed horizontally on the welding roller frame 100, the outer wall of the cylinder and the contact surface of each roller 121 are basically the same, and each roller 121 provides a similar support force to the cylinder, thereby avoiding uneven force causing the outer wall of the cylinder to be concave.

[0030] like Figure 2 and Figure 3 As shown, in some embodiments of the present invention, the roller 121 frame further includes a roller assembly support plate 130. The roller assembly support plate 130 is symmetrically arranged above the base 110, and the roller assembly 120 is connected to the base 110 through the roller assembly support plate 130.

[0031] In this embodiment, the roller assembly support plate 130 is located between the roller assembly 120 and the base 110. The roller assembly 120 is connected to the roller assembly support plate 130 above the roller assembly support plate 130. The roller assembly support plate 130 withstands the pressure transmitted by the roller assembly 120 and transmits the pressure transmitted by the roller assembly 120 to the base 110.

[0032] Furthermore, if Figure 2 As shown, in some embodiments of the present invention, the length of the roller assembly support plate 130 is greater than the width of the base 110 , and the roller assemblies 120 are symmetrically arranged at both ends of the roller assembly support plate 130 .

[0033] In this embodiment, the roller assembly 120 is arranged at both ends of the roller assembly support plate 130, and the width of the base 110 can be smaller than the distance between the two roller assemblies 120 at the same end of the base 110. The arrangement of the roller assembly support plate 130 enables the material of the base 110 to be saved while ensuring the distance between the two roller assemblies 120.

[0034] In some other embodiments of the present invention, at least one roller assembly support plate 130 is movably disposed above the base 110 .

[0035] In this embodiment, at least one roller assembly support plate 130 can move along the length direction of the base 110. When the roller assembly support plate 130 can move along the length direction of the base 110, the distance between the two roller assembly support plates 130 changes, which can be suitable for cylinders with different diameters.

[0036] like Figure 3As shown, in some embodiments of the present invention, the roller assembly 120 and the roller assembly support plate 130 are connected by an elastic member 150. The roller assembly 130 and the roller assembly support plate 130 are connected by the elastic member 150. When the cylinder is placed on the welding roller frame 100, the elastic member 150 is elastically deformed under the action of the external force of the tower body. In particular, when the cylinder is conical, the elastic members 150 connected to different roller assemblies 120 along the length direction of the cylinder undergo different elastic deformations, specifically, the elastic deformation amount of the elastic member 150 close to the top of the cone is greater than the elastic deformation amount of the elastic member 150 near the top of the cone.

[0037] In this embodiment, the roller assembly 120 and the roller assembly support plate 130 are connected by the elastic member 150, which can improve the stability of the contact surface when the cylinder is a cone structure.

[0038] In some embodiments of the present invention, the welding roller frame 100 further includes a rolling device 140 , and the rolling device 140 is connected to the base 110 , so that the welding roller frame 100 is driven to move when the rolling device 140 moves.

[0039] In this embodiment, when the rolling device 140 moves, it drives the welding roller frame 100 to move, so that the position of the welding roller frame 100 can be adjusted simply and conveniently.

[0040] Furthermore, in some embodiments of the present invention, a pulley is provided at the bottom of the rolling device 140 to enable the welding roller frame 100 to move.

[0041] Specifically, the pulley slides, driving the rolling device 140 to move, thereby causing the welding roller frame 100 to move.

[0042] In some embodiments of the utility model, the welding roller frame 100 includes a base 110, a roller assembly 120, a roller assembly support plate 130 and a rolling device 140. Two roller assembly support plates 130 are movably arranged on the upper surface of the base 110, and two roller assemblies 120 are symmetrically arranged on each roller assembly support plate 130. The roller assembly 120 includes a roller bracket 122 and a roller 121 rotatably arranged on the roller bracket 122, and the roller 121 is connected to the roller assembly support plate 130 through the roller bracket 122. The rolling device 140 is arranged below the base 110 and connected to the lower surface of the base 110.

[0043] Before welding the cylinder, two pairs of the welding roller frames 100 are placed in parallel on the track; then, the cylinder is placed on the welding roller frame 100 so that both ends of the cylinder are in contact with the rollers 121 of the welding roller frame 100. During the rotation of the cylinder, the rollers 121 are effectively combined with the outer wall of the cylinder and the force-bearing surface of the outer wall plate of the cylinder is increased, so as to prevent the outer wall plate of the cylinder from being concave and affecting the product quality.

[0044] At this point, those skilled in the art should recognize that, although multiple exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications that conform to the principles of the present invention can still be directly determined or derived from the contents disclosed in the present invention without departing from the spirit and scope of the present invention.
