Description

Technical Field

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

[0002] Adjustable welding roller frame is a welding device that adjusts the roller center distance through reserved screw holes or screws to adapt to changes in the workpiece diameter. Its driving method usually adopts a cycloidal pinwheel reducer or a worm gear reducer, and is driven by dual motors. The roller frame is mainly used for welding, polishing, rubber lining and assembly of cylindrical barrels, and can also be used in conjunction with other tooling for the assembly and welding of cones and segmented unequal diameter rotating bodies. Adjustable welding roller frames are widely used in wind power, pressure vessels, petrochemicals, pipelines, steel structures, boilers, shipbuilding, surfacing repair and other industries.

[0003] The existing roller frame has an unadjustable swing angle, and the roller frame can only adapt to workpieces of specific sizes and shapes. If the diameter or shape of the workpiece changes, the roller frame may not be able to provide stable support and rotation, which will limit the scope of use of the roller frame. When faced with workpieces of different sizes, the roller frame that cannot adjust the swing angle may need to be frequently replaced or adjusted with other tooling to adapt, which will increase operation time and work complexity, reduce work efficiency, and reduce its versatility and flexibility.

[0024] The transmission mechanism includes a first bevel tooth 801 , one side of the first bevel tooth 801 is meshedly connected with a second bevel tooth 802 , and one side of the second bevel tooth 802 is fixedly connected with a second sprocket 803 .

[0025] A connecting column 804 is fixedly connected to one side of the second sprocket 803, and one end of the connecting column 804 is rotatably connected to the inner wall of the base 1. A chain belt 805 is sleeved on the outer side of the first sprocket 5 and the second sprocket 803, and the first sprocket 5 and the second sprocket 803 are connected through the chain belt 805.

[0026] The working principle of this embodiment is as follows: when it is necessary to adjust the swing angle of the roller frame, the first connecting rod 6 and the second connecting rod 7 are rotated, and the first connecting rod 6 and the second connecting rod 7 drive the first bevel gear 801 to rotate, and the first bevel gear 801 drives the second bevel gear 802 to rotate, and the second bevel gear 802 drives the second sprocket 803 to rotate. When the second sprocket 803 rotates, its own position is limited by the connecting column 804, so that the second sprocket 803 will not shift when it rotates, and then the second sprocket 803 drives the first sprocket 5 to rotate through the chain belt 805, and the first sprocket 5 drives the fixed column 3 to rotate, and the fixed column 3 will drive the roller body 4 to rotate. After the roller body 4 rotates, the angle between it and the base 1 will be adjusted accordingly, thereby achieving the effect of adjusting the swing angle of the roller body 4. The roller frame with swing adjustment angle can cope with workpieces of different shapes and sizes, whether it is a cylinder with a larger diameter or a smaller workpiece, or even some irregularly shaped objects, by adjusting the angle of the roller, stable support and rotation can be achieved, thereby greatly improving the scope of application and flexibility of the roller frame.

[0027] Embodiment 2

[0028] This embodiment is an improvement made on the basis of the first embodiment. For details, please refer to Figures 1 to 4 The outer side of the first connecting rod 6 is fixedly connected with a first connecting sleeve 9, and the outer side of the second connecting rod 7 is slidably connected with a second connecting sleeve 10.

[0029] A base plate 11 is fixedly connected to the outer side of the second connecting rod 7 , a spring 12 is fixedly connected to one side of the base plate 11 , and one end of the spring 12 is fixedly connected to the second connecting sleeve 10 .

[0030] A connecting plate 13 is fixedly connected to one side of the first connecting sleeve 9 , an extending plate 14 is rotatably connected to one side of the connecting plate 13 , a sliding groove 15 is provided inside the second connecting sleeve 10 , and the connecting plate 13 and the extending plate 14 are slidably connected to the sliding groove 15 .

[0031] By setting the first connecting sleeve 9, the second connecting sleeve 10, the base plate 11, the spring 12, the connecting plate 13 and the extension plate 14, in the initial state, the elastic force of the spring 12 will push the second connecting sleeve 10 to fit with the first connecting sleeve 9. When the two fit together, the second connecting sleeve 10 is connected to the first connecting sleeve 9 through the connecting plate 13 and the extension plate 14. At this time, rotating one of the first connecting sleeve 9 or the second connecting sleeve 10 can drive the other to rotate, thereby making the first connecting rod 6 and the second connecting rod 7 rotate synchronously, which is convenient for the synchronous adjustment of the two roller bodies 4. When the first connecting rod 6 and the second connecting rod 7 need to be adjusted separately, the second connecting sleeve 10 can be moved to the right side so that the second connecting sleeve 1 0 is completely separated from the internal extension plate 14, and then the extension plate 14 is rotated to be vertical to the connecting plate 13, and then the second connecting sleeve 10 is loosened. The second connecting sleeve 10 will fit with the upright connecting plate 13 under the elastic force of the spring 12. At this time, rotating the first connecting sleeve 9 can only drive the first connecting rod 6 to rotate, and the first connecting rod 6 will drive the roller body 4 on the left side of the top of the base 1 to adjust. When the second connecting sleeve 10 is rotated, it will only drive the roller body 4 on the right side of the top of the base 1 to adjust. By adjusting the position of the second connecting sleeve 10, the synchronization state of the first connecting rod 6 and the second connecting rod 7 can be changed, thereby improving the adjustment applicability of the roller body 4 and further improving the practicality of the welding roller frame.

[0032] A sliding plate 16 is fixedly connected to the outer side of the second connecting rod 7 , and the sliding plate 16 is slidably connected to the sliding groove 15 .

[0033] By setting the sliding plate 16, when the second connecting sleeve 10 is separated from the extension plate 14, the sliding plate 16 will contact the second connecting sleeve 10 through the sliding groove 15, so that the second connecting sleeve 10 is limited, and the second connecting sleeve 10 can drive the second connecting rod 7 to rotate through the sliding plate 16, so that the roller body 4 on the top right side of the base 1 can be adjusted normally.

[0034] The outer sides of the first connecting rod 6 and the second connecting rod 7 are both rotatably connected with a fixing ring 17 , and one side of the fixing ring 17 is fixedly connected to the base 1 .

[0035] By setting the fixing ring 17, the fixing ring 17 can have a limiting effect on the first connecting rod 6 and the second connecting rod 7, so that the first connecting rod 6 and the second connecting rod 7 are more stable when rotating and are less likely to shake and shift during rotation.

[0036] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0037] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
