Description

Technical Field

[0001] The utility model belongs to the technical field of welding equipment, and particularly relates to a cylinder welding auxiliary equipment. Background Art

[0002] At present, the welding of pressure vessels, wind turbine towers, and circular workpieces is basically done using adjustable welding rollers, and is only suitable for welding circular cylindrical workpieces. Due to the different diameters of the workpieces, the welding roller and the spacing between the two rollers on the welding roller are manually adjusted to accommodate workpieces of different diameters. Since the workpiece is non-circular in shape, such as an elliptical cylinder or a polygonal cylinder, when the workpiece is placed on the equipment, the angle of contact between the workpiece and the lower roller is too small, which can easily cause overturning or the workpiece cannot rotate normally. Therefore, for elliptical cylinders and polygonal cylinders, traditional welding rollers cannot be used, and manual welding can only be used, which is inefficient, slow, and more labor-intensive. Summary of the invention

[0003] The purpose of the utility model is to solve the problems of the prior art and proposes a cylinder welding auxiliary equipment, which can automatically adjust the spacing between two groups of roller pairs according to workpieces of different diameters without the need for manual adjustment of the roller spacing, thus saving time and effort; on the other hand, the equipment is not only suitable for circular cylinder workpieces, but also for elliptical cylinders and polygonal cylinder workpieces.

[0004] To achieve the above purpose, the technical solution adopted is:

[0005] The utility model provides a cylinder welding auxiliary equipment, comprising a track, on which a first group of roller frames, a second group of roller frames, a first welding roller frame and a second welding roller frame are arranged in sequence from left to right, the first group of roller frames, the second group of roller frames, the first welding roller frame and the second welding roller frame each include two groups of symmetrically arranged roller pairs, the two groups of roller pairs are rotated to adjust the spacing according to the diameter of the cylinder, and each group of roller pairs includes two upper and lower rollers in contact with the workpiece; the first group of roller frames and the first welding roller frame include a walking mechanism; the workpiece 1 is placed on the roller pairs of the first group of roller frames and the second group of roller frames, and the workpiece 2 is placed on the roller pairs of the first welding roller frame and the second welding roller frame, and the workpiece 1 is group-welded with the workpiece 2.

[0006] According to the cylinder welding auxiliary equipment of the utility model, further, the first group of roller frames and the second group of roller frames both include a first frame straddling the track, two mounting seats are arranged on the first frame, each mounting seat is hinged to the inner end of the clamp-shaped automatic swing arm, and each group of roller pairs is hinged in the clamp-shaped automatic swing arm; the outer end of the clamp-shaped automatic swing arm is hinged to the first lifting mechanism, and the first lifting mechanism is hinged on the first frame.

[0007] According to the cylinder welding auxiliary equipment of the utility model, further, the two groups of rollers of the first pair of roller frames are each provided with a blocking wheel for blocking the workpiece 1 on the outer side.

[0008] According to the cylinder welding auxiliary equipment of the utility model, further, two correction wheels are arranged between the two groups of roller pairs of the second group of roller frames, which are respectively located at the bottom of workpiece 1 and workpiece 2; the lower end of the correction wheel is hinged to the second lifting mechanism, and the second lifting mechanism is hinged on the first frame.

[0009] According to the cylinder welding auxiliary equipment of the utility model, further, the rollers of the second group of roller frames are grooved wheels, and the welding seams of the workpieces 1 and 2 are located at the grooves of the grooved wheels.

[0010] According to the cylinder welding auxiliary equipment of the utility model, further, the first welding roller frame and the second welding roller frame both include a second frame straddling the track, the second frame is provided with two U-shaped bases, and each group of roller pairs is hingedly arranged in the U-shaped base.

[0011] According to the cylinder welding auxiliary equipment of the utility model, further, two rotating motors are arranged on the second frame of the first welding roller frame, and each rotating motor drives the two rollers to rotate through gear transmission.

[0013] The beneficial effects achieved by adopting the above technical solution are:

[0014] 1. The traditional welding roller rack needs to manually adjust the roller spacing according to the workpiece diameter to adapt to the circular cylinders of different diameters. The roller spacing of the first roller rack and the second roller rack of the utility model can be adjusted by automatic rotation in the clamp-shaped automatic swing arm according to the workpiece diameter. The roller spacing of the first welding roller rack and the second welding roller rack can be adjusted by automatic rotation in the U-shaped base according to the workpiece diameter, which saves time and effort and saves labor costs.

By increasing the number of rollers, the contact area with the workpiece is increased, which effectively supports the rotational welding of elliptical cylindrical and polygonal cylindrical workpieces, and has a wider range of applications.

[0016] 3. The conventional method can only rely on the movement of the welding roller frame to drive the workpiece close to the other workpiece that needs to be assembled, which is a single method. The utility model is provided with a walking mechanism on both workpieces, which can move close to each other for assembly and welding, and the movement form is more flexible.

[0017] 4. When the traditional welding roller frame is used for assembly, the joint of the two workpieces is located between the assembly roller frame and the welding roller frame, and there is no supporting mechanism below. The joint can only be checked manually using tools to see if it is smooth. The utility model places the joint of the two workpieces on the groove wheel, and uses the second lifting mechanism and correction wheel under the two workpieces to adjust the smoothness of the joint, further improving the quality of the finished welding product and avoiding misaligned welding.

[0033] The following will be combined with the drawings of the specific embodiments of the utility model to clearly and completely describe the exemplary scheme of the utility model. Unless otherwise defined, the technical terms or scientific terms used in the utility model should be the common meanings understood by people with ordinary skills in the relevant field.

[0034] like Figure 1 As shown, the cylinder welding auxiliary equipment of this embodiment includes a track 1, on which the first group of roller frames 3, the second group of roller frames 4, the first welding roller frame 5 and the second welding roller frame 6 are arranged from left to right. The first group of roller frames 3, the second group of roller frames 4, the first welding roller frame 5 and the second welding roller frame 6 each include two groups of symmetrically arranged roller pairs 2, and the two groups of roller pairs 2 rotate and automatically adjust the spacing according to the diameter of the cylinder, avoiding time-consuming and labor-intensive manual adjustment. Each group of roller pairs 2 includes two upper and lower rollers 201 that contact the workpiece. Compared with the original one group of roller frames / welding roller frames with two rollers 201, the number of rollers 201 is increased, and the contact area with the workpiece is increased, so as to achieve stable support of elliptical and polygonal cylinder workpieces. The first group of roller frames 3 and the first welding roller frame 5 include a walking mechanism 7, which respectively drives the two sections of the workpiece to move toward each other. A circular cylindrical, elliptical cylindrical or polygonal cylindrical workpiece 1 is placed on the roller pair 2 of the first pair of roller frames 3 and the second pair of roller frames 4, and the workpiece 2 is placed on the roller pair 2 of the first welding roller frame 5 and the second welding roller frame 6, and the two sections of the workpiece are welded together.

[0035] like Figure 2 , Figure 3 and Figure 4As shown, the first set of roller frames 3 and the second set of roller frames 4 both include a first frame 301 straddling the track 1, two mounting seats 302 are fixed on the first frame 301, each mounting seat 302 is hinged to the inner side end of the clamp-shaped automatic swing arm 303, and each set of roller pairs 2 is hinged in the clamp-shaped automatic swing arm 303, so that the roller 201 can rotate adaptively according to the diameter of the workpiece to adapt to the diameter size. The outer side end of the clamp-shaped automatic swing arm 303 is hinged to the first lifting mechanism 304, and the first lifting mechanism 304 is hinged on the first frame 301. The four first lifting mechanisms 304 adjust the alignment of the joints of the two sections of the workpiece.

[0036] The outer side surfaces of the two roller pairs 2 of the first roller frame 3 are each provided with a blocking wheel 305 for blocking the workpiece 1 . Driven by the traveling mechanism 7 , the blocking wheel 305 pushes the workpiece 1 to move toward the outer end surface of the workpiece 2 .

[0037] like Figure 4 As shown, two correction wheels 401 are arranged between the two roller pairs 2 of the second roller frame 4, and are respectively located at the bottom of the workpiece 1 and the workpiece 2. The lower end of the correction wheel 401 is hinged to the second jacking mechanism 402, and the second jacking mechanism 402 is hingedly arranged on the first frame 301. The first jacking mechanism 304 is first used to align the outer end surfaces of the two workpieces, and then the two second jacking mechanisms 402 are used to align and splice the bottom of the workpieces. Optionally, the first jacking mechanism 304 and the second jacking mechanism 402 use oil cylinders.

[0038] The rollers 201 of the second pair of roller frames 4 are grooved wheels 403 , and the welds between the workpieces 1 and 2 are located at the grooves of the grooved wheels 403 , providing an avoidance space for the welds.

[0039] like Figure 5 and Figure 6 As shown, the first welding roller frame 5 and the second welding roller frame 6 both include a second frame 501 straddling the track 1, and two U-shaped bases 502 are arranged on the second frame 501. Each group of roller pairs 2 is hingedly arranged in the U-shaped base 502, and the two groups of roller pairs 2 rotate in the U-shaped base 502 according to the diameter of the workpiece to adjust the distance between them.

[0040] Two rotating motors 503 are also arranged on the second frame 501 of the first welding roller frame 5. Each rotating motor 503 drives the two rollers 201 to rotate through gear transmission, so that the two workpieces are rotated together to different angles for spot welding first, and then the rotating motor 503 rotates at a certain speed to realize filling welding.

[0041] The walking mechanism 7 of the first pair of roller frames 3 is fixed on the side of the first frame 301, and the walking mechanism 7 of the first welding roller frame 5 is fixed on the side of the second frame 501. The walking mechanism 7 includes a walking motor 701, and the walking motor 701 is connected to the walking wheel 703 through a gear box 702, driving the walking wheel 703 to move linearly along the track 1; the bottom of the second frame 501 of the second welding roller frame 6 is also designed with a walking wheel 703 that moves along the track 1; thereby realizing the position movement of the workpiece 1 and the workpiece 2 on the track 1.

[0042] Here’s how it works:

[0043] First, the workpiece 1 is placed on the first set of roller frames 3 and the second set of roller frames 4 , and the workpiece 2 is placed on the first welding roller frame 5 and the second welding roller frame 6 .

[0044] Then, the blocking wheel 305 and the walking mechanism 7 of the first pairing roller frame 3 are used to move the end of the workpiece 1 that needs to be paired to the middle of the groove wheel 403; the first welding roller frame 5 and the second welding roller frame 6 drive the workpiece 2 so that the end of the workpiece 2 that needs to be paired moves to the middle of the groove wheel 403 and contacts the workpiece 1.

[0045] Next, one or more first lifting mechanisms 304 are used to align and spot-join the outer sides of the two workpieces, and then two correction wheels 401 are used to align and splice the bottoms of the workpieces, and spot welding is performed at the aligned parts.

[0046] The rotary motor 503 is started to drive the two workpieces to rotate, for example, 30°, and then the alignment splicing operation is repeated, and the alignment position is spot welded until 360° spot welding is completed. Finally, under the action of the rotary motor 503, the filling welding of the two workpieces is realized.

[0047] The utility model has two groups of symmetrically arranged roller pairs 2 which automatically adjust the spacing according to the diameter of the cylinder, and can be applicable to the group welding of circular cylinders, elliptical cylinders and polygonal cylinder workpieces.
