Description

Technical Field

[0001] This utility model relates to the field of roller frame equipment technology, and in particular to a roller frame for welding internal partitions of a cylinder. Background Technology

[0002] The existing large-diameter oil tank cylinders have thin sidewalls, making them prone to deformation. Therefore, it is necessary to weld and fix internal baffles inside the cylinder to support it and reduce the degree of deformation. The internal baffles are generally fixed inside the cylinder by welding. The existing roller frame can only support the cylinder and drive its rotation. In the event of cylinder deformation, it cannot effectively help the subsequent internal baffles to enter the cylinder. Summary of the Invention

[0003] To address the problem that existing roller frames cannot effectively assist the subsequent entry of inner partitions into the cylinder when the cylinder body is deformed, this utility model proposes a roller frame for welding inner partitions in a cylinder. The cylinder body is held tightly by the clamping arm plate in the clamping arm assembly, thereby ensuring the roundness of the cylinder body and making it easier for the inner partitions to enter the cylinder body.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows:

[0005] A roller frame for welding internal partitions of a cylinder includes a base and a sixth power mechanism. A support bracket is fixed on the base. Two sets of opposing rollers are rotatably mounted on the upper end of the support bracket for placing the cylinder. The sixth power mechanism drives the roller sets to rotate. Multiple clamping arm assemblies for clamping the cylinder are provided on both sides of the support bracket. Each clamping arm assembly includes a second telescopic mechanism, a side support frame, a third telescopic mechanism, and a clamping arm plate. The side support frame is located on one side of the cylinder and its lower end is hinged to the support bracket. One end of the second telescopic mechanism is hinged to the support bracket, and the other end is hinged to the side support frame. The second telescopic mechanism is located on the side of the side support frame away from the cylinder. The third telescopic mechanism is fixed to the side support frame. The clamping arm plate is located between the side support frame and the cylinder. The output end of the third telescopic mechanism extends out of the side support frame and is connected and fixed to one side of the clamping arm plate. The side of the clamping arm plate closest to the cylinder is in contact with the outer surface of the cylinder.

[0006] Preferably, a fixing rod is fixed to the upper end of the support bracket, and a support block is fixed on the fixing rod. Each set of rollers includes multiple rollers, and the roller shaft of one roller passes through the support block and is connected and fixed to the roller shaft of another roller through a coupling.

[0007] Preferably, a fourth hinge seat is fixed on the support bracket, the lower end of the side support frame is hinged to the fourth hinge seat, a first hinge shaft is fixed on the side support frame, and the end of the second telescopic mechanism is hinged to the first hinge shaft.

[0008] Preferably, the side support frame is provided with a guide assembly, which includes multiple guide rods and a guide plate fixedly connected to the multiple guide rods. One end of each guide rod passes through the side support frame and is fixedly connected to the side of the arm plate away from the cylinder. The guide plate is located on the side of the guide rod away from the arm plate.

[0009] Preferably, the side support frame is V-shaped.

[0010] Preferably, an anti-slip assembly is provided above the base. The anti-slip assembly includes an anti-slip mounting base, an anti-slip pin, and an anti-slip roller. The anti-slip roller is sleeved on the anti-slip pin, the anti-slip pin is fixed on the anti-slip mounting base, and the anti-slip roller is in contact with the end of the cylinder.

[0011] Through the above technical solution, the beneficial effects of this utility model are as follows: The second telescopic mechanism in the arm assembly of this utility model can control the side support frame to approach the cylinder. After moving to a suitable distance, the third telescopic mechanism drives the arm plate to fit against the outer side of the cylinder, thereby achieving the clamping of the arm plate against the cylinder and ensuring the roundness of the cylinder. This makes it easier for the inner partition to enter the cylinder. After the inner partition enters the cylinder, the roundness of the cylinder is ensured by the inner partition. At this time, the third telescopic mechanism drives the arm plate away from the cylinder, and the sixth power mechanism drives the roller group and the cylinder to rotate, which is more conducive to the subsequent welding of the inner partition and the cylinder circumference weld by the welding torch.

[0030] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0031] This embodiment provides a welding system for a cylinder inner partition, including a base 1, a feeding device 2, a welding device 3, and a roller frame for welding the cylinder inner partition. The base 1 is provided with a horizontally arranged cylinder 4, and the roller frame is arranged horizontally, with the cylinder 4 placed on the roller frame.

[0032] refer to Figures 10-13 The roller frame includes a support bracket 11 bolted to the base 1 and a sixth power mechanism 10. Two sets of opposing rollers 12 are rotatably mounted on the upper end of the support bracket 11 for placing the cylinder 4. For details, please refer to... Figure 12 The upper end of the support bracket 11 is welded and fixed with a fixing rod 14, and a support block 15 is bolted to the fixing rod 14. Each set of rollers 12 includes multiple rollers 121. The roller shaft 122 of the roller 121 passes through the support block 15 and is connected and fixed to the roller shaft 122 of another roller 121 through a coupling 123. The roller shaft 122 is rotatably mounted on the support block 15 through a bearing.

[0033] Furthermore, the sixth power mechanism 10 drives the roller group 12 to rotate. The sixth power mechanism 10 adopts a combination of motor and reducer. The output end of the reducer is fixedly connected to the roller shaft 122 of the roller 121. The two sixth power mechanisms 10 drive the two roller groups 12 to rotate in the same direction.

[0034] Meanwhile, in order to prevent the inner partition 5 from being unable to enter the cylinder 4 due to deformation of the cylinder 4 when the feeding device 2 sends the inner partition 5 into the cylinder 4, three clamping arm assemblies 13 for clamping the cylinder 4 are provided on both sides of the support bracket 11. The clamping arm assembly 13 includes a second telescopic mechanism 131, a side support frame 132, a third telescopic mechanism 133 and a clamping arm plate 134. The second telescopic mechanism 131 and the third telescopic mechanism 133 can be cylinders or hydraulic cylinders.

[0035] The side support frame 132 is located on one side of the cylinder 4 and its lower end is hinged to the support bracket 11. The side support frame 132 is V-shaped with an obtuse angle, which can effectively save space. Specifically, a fourth hinge seat 16 is fixed on the support bracket 11, and the lower end of the side support frame 132 is hinged to the fourth hinge seat 16. One end of the second telescopic mechanism 131 is hinged to the support bracket 11, and the other end is hinged to the side support frame 132. A first hinge shaft 1321 is fixed on the side support frame 132, and the end of the second telescopic mechanism 131 is hinged to the first hinge shaft 1321. The second telescopic mechanism 131 is located on the side of the side support frame 132 away from the cylinder 4.

[0036] Furthermore, the third telescopic mechanism 133 is fixed on the side support frame 132, and the arm plate 134 is located between the side support frame 132 and the cylinder 4. The output end of the third telescopic mechanism 133 extends out of the side support frame 132 and is fixed to one side of the arm plate 134 by bolts. The side of the arm plate 134 near the cylinder 4 is in contact with the outer side of the cylinder 4.

[0037] In this embodiment, the telescopic control side support frame 132 of the second telescopic mechanism 131 moves closer to or further away from the cylinder. When the cylinder 4 needs to be placed on the roller assembly 12, in order to avoid positional interference, the control side support frame 132 of the second telescopic mechanism 131 moves away from the cylinder 4. After the cylinder 4 is placed, the control side support frame 132 of the second telescopic mechanism 131 moves closer to the cylinder 4. After moving to a suitable distance, the third telescopic mechanism 133 drives the arm plate 134 to fit against the outer side of the cylinder 4 to prepare for the inner partition 5 to be placed into the cylinder 4. After the inner partition 5 is placed into the cylinder 4, the third telescopic mechanism 133 drives the arm plate 134 to move away from the cylinder 4. During the welding process of the welding device, the sixth power mechanism 10 drives the cylinder 4 to rotate, thereby realizing the welding of the inner partition 5 and the cylinder 4 around the weld seam.

[0038] refer to Figure 11 In order to achieve stability in the movement of the arm plate 134, a guide assembly is provided on the side support frame 132. The guide assembly includes two guide rods 171 and a guide plate 172 fixedly connected to the two guide rods 171. One end of the guide rod 171 passes through the side support frame 132 and is fixedly connected to the side of the arm plate 134 away from the cylinder 4. The guide plate 172 is located on the side of the guide rod 171 away from the arm plate 134.

[0039] refer to Figure 13An anti-slip assembly is provided above the base 1. An anti-slip support 184 is welded and fixed to the support bracket 11. The anti-slip assembly includes an anti-slip mounting base 181, an anti-slip pin 182, and an anti-slip roller 183. The anti-slip mounting base 181 is fixed to the upper end of the anti-slip support 184 by bolts. The anti-slip roller 183 is sleeved on the anti-slip pin 182, and the anti-slip pin 182 is fixed to the anti-slip mounting base 181. The anti-slip roller 183 contacts the end of the cylinder 4. This prevents the cylinder 4 from moving laterally when the inner partition 5 enters the cylinder 4.

[0040] In this embodiment, the arm assembly 13 holding the cylinder 4 is a preparatory work for the feeding device 2 to send the inner partition 5 into the cylinder 4, so as to avoid the inner partition 5 being unable to enter the cylinder 4 due to deformation of the cylinder 4. The following describes how the feeding device 2 realizes the transportation of the inner partition 5.

Two symmetrical vertical slide rails are provided on the column 6. A slider that cooperates with the slide rails is fixed on the side of the column slide plate 61 near the column 6 to achieve a sliding connection between the column slide plate 61 and the column 6. A vertical first lead screw 62 is rotatably mounted on the side of the column 6 near the column slide plate 61. The lower end of the first lead screw 62 is rotatably mounted on the column 6. A first power mechanism 64 is fixed on the column 6. The output end of the first power mechanism 64 is fixedly connected to the upper end of the first lead screw 62. The first power mechanism 64 can be a motor. A first connecting block 63 is fixed on the side of the column slide plate 61 near the column 6. The first lead screw 62 passes through the first connecting block 63 and is threadedly connected to the first connecting block 63. This enables the vertical movement of the column slide plate 61 on the column 6 under the control of the first power mechanism 64.

[0044] refer to Figure 5The horizontal arm 21 can move laterally along the base 1. The horizontal arm 21 is laterally slidably mounted on the column slide plate 61. Two laterally arranged slide rails are fixed to the side of the horizontal arm 21 near the column slide plate 61. A slider that cooperates with the slide rails is fixed to the side of the column slide plate 61 near the horizontal arm 21. A second power mechanism 611, which can be a motor, is fixed to the column slide plate 61. A first transverse rack 612 is fixed to the side of the horizontal arm 21 near the column slide plate 61. A first gear that meshes with the first rack 612 is fixed to the output end of the second power mechanism 611. This allows the horizontal arm 21 to move laterally on the column slide plate 61 under the control of the second power mechanism 611.

[0045] refer to Figure 2 A horizontal sliding plate 27 is laterally slidable on the side of the horizontal arm 21. Two horizontal slide rails are fixed to the side of the horizontal arm 21 near the sliding plate 27. A slider that cooperates with the slide rails is fixed to the sliding plate 27 near the horizontal arm 21. The sliding plate 27 is located on the side of the horizontal arm 21 away from the column sliding plate 61. A third power mechanism 271, which can be a motor, is fixed on the sliding plate 27. A horizontal second rack 272 is fixed to the side of the horizontal arm 21 away from the column sliding plate 61. A second gear that meshes with the second rack 272 is fixed to the output end of the third power mechanism 271. This enables the horizontal movement of the sliding plate 27 on the horizontal arm 21 under the control of the third power mechanism 271.

[0046] Furthermore, the feeding device 2 also includes a support base 22, a support frame 23, a suction cup 24, and a first telescopic mechanism 25.

[0047] refer to Figure 3 The support base 22 is disposed on the side of the cross arm 21 near the cylinder 4. A sliding seat 26 is also fixed at the end of the cross arm 21 near the support base 22. The support base 22 is vertically slidably disposed on the sliding seat 26. Specifically, the support base 22 includes a support plate 221 and a sliding plate 222. The sliding plate 222 is located on the side of the support plate 221 away from the cross arm 21. The sliding plate 222 is longitudinally slidably disposed on the support plate 221. The end of the support plate 221 is provided with a limiting part for limiting the sliding of the sliding plate 222.

[0048] The support plate 221 has two longitudinally fixed slide rails on the side near the sliding plate 222. The sliding plate 222 has a slider that cooperates with the slide rails on the side near the support plate 221. The sliding plate 222 can slide freely on the support plate 221. When the inner partition 5 is blocked when entering the cylinder 4, the sliding plate 222 adaptively moves a certain distance on the support plate 221, which facilitates the inner partition 5 to enter the cylinder 4.

[0049] In this embodiment, a vertical slide rail is fixed to the side of the sliding seat 26 near the support plate 221, and a slider that cooperates with the slide rail is fixed to the side of the support plate 221 near the sliding seat 26. A vertical second lead screw 261 is rotatably mounted on the sliding seat 26. A second connecting block is fixed to the side of the support seat 22 near the sliding seat 26. The second lead screw 261 passes through the second connecting block and is threadedly connected to the second connecting block. A fourth power mechanism 263 is fixed to the sliding seat 26. The fourth power mechanism 263 can be a motor, and its output end is fixedly connected to the end of the second lead screw 261. Under the control of the fourth power mechanism 263, the support seat 22 moves vertically up and down on the sliding seat 26.

[0050] refer to Figure 2 The support frame 23 is hinged to the support base 22 on the side away from the cross arm 21. The suction cup 24 is fixed to the support frame 23 on the side away from the support base 22 and is used to adsorb the inner partition 5. The support frame 23 is provided with suction cups 24 at all four corners. The first telescopic mechanism 25 is hinged at one end to the support base 22 and at the other end to the support frame 23. The suction cup 24 is existing technology and is purchased from outside. Vacuum suction cups from Anhui Metel Vacuum Handling Equipment Co., Ltd. can be used.

[0051] Specifically, a first hinge seat 223 is fixed on the sliding plate 222, and the first telescopic mechanism 25 can be a cylinder or a hydraulic cylinder. The first hinge seat 223 is hinged to one end of the cylinder seat of the first telescopic mechanism 25.

A hinge plate 231 and a third hinge seat 232 are fixed on the side of the support frame 23 close to the sliding plate 222. The hinge plate 231 is located in the middle of the support frame 23. The second hinge seat 224 is hinged to the hinge plate 231, and the third hinge seat 232 is hinged to the telescopic end of the first telescopic mechanism 25.

[0052] After the suction cup 24 adsorbs the inner partition 5, in order to allow the inner partition 5 to smoothly enter the cylinder 4, the first telescopic mechanism 25 can be controlled to extend and retract, and then the inner partition 5 will be tilted, so that the inner partition 5 can enter the cylinder 4 more easily. After it is in place, the first telescopic mechanism 25 is controlled to push the inner partition 5 straight, and then the welding device 3 is controlled to weld and fix it; the welding device 3 is described below.

[0053] refer to Figure 1 and Figure 6The welding device 3 is fixed on the horizontal arm slide plate 27 and is used to weld the inner partition plate 5 to the inner side of the cylinder 4. The welding device 3 includes a welding torch 32 and a sliding frame 33 fixed to one end of the horizontal arm slide plate 27 near the cylinder 4. A fifth power mechanism 34 is fixed on the sliding frame 33. The fifth power mechanism 34 can be a reducer. A first fixing plate 35 is fixed to the output end of the fifth power mechanism 34. The welding torch 32 is bolted to the first fixing plate 35. A second fixing plate 36 is also bolted to one side of the sliding frame 33. A laser weld seam tracker 37 is fixed on the second fixing plate 36 for sensing the weld position between the inner partition plate 5 and the cylinder 4. The laser weld seam tracker 37 can be a sensor of model CXZK-RBTA4-S.

[0054] Specifically, a cross slide 38 is fixed to one end of the sliding frame 33 near the cylinder 4. A welding support plate 39 is fixed to the slider 381 of the cross slide 38. The fifth power mechanism 34 is fixed to the end of the welding support plate 39 near the cylinder 4, and the second fixing plate 36 is fixed to one side of the welding support plate 39. The cross slide 38 is existing technology and was purchased externally, so it will not be described in detail. In this embodiment, the welding device 3 is slidably mounted on the cross arm 21 via the cross arm slide plate 27, so that the welding device 3 moves closer to or away from the cylinder 4 under the drive of the third power mechanism 271, thereby avoiding positional interference between the welding device 3 and the inner partition 5 during installation.

[0055] Meanwhile, to facilitate the automated welding of the inner partition 5, refer to Figure 1 , Figures 7-9 The welding system also includes a placement frame 7 on the base 1 for placing the inner partition 5. The placement frame 7 includes a base frame 71, a first frame 72, a second frame 73, and a quick clamp 74. The base frame 71 is fixed on the base 1. The two first frames 72 are arranged opposite to each other on the base frame 71. The first frame 72 is located on one side of the inner partition 5 and contacts the side of the inner partition 5. The second frame 73 is fixed on the side of the first frame 72 and contacts the outer periphery of the inner partition 5. The quick clamp 74 is fixed at the end of the second frame 73 away from the first frame 72 and is used to limit the other side of the inner partition 5.

[0056] A stop block 75 is fixed at the upper end of the base frame 71 to limit the lower end of the inner partition 5; the quick clamp 74 can open and close quickly. The quick clamp 74 can be opened after the inner partition 5 is attracted by the suction cup 24. The quick clamp is purchased from outside and is existing technology. The manufacturer is Dongguan Yiheda Automation Co., Ltd., and the model is WDC12050-U120.

[0057] The usage process of the internal partition welding system of this cylinder:

[0058] First, place cylinder 4 on the roller frame (see reference). Figure 11 The specific process is as follows: the second telescopic mechanism 131 drives the side support frame 132 away from the cylinder 4. After the cylinder 4 is placed on the two roller groups 12, the second telescopic mechanism 131 controls the side support frame 132 to approach the cylinder 4. After moving to a suitable distance, the third telescopic mechanism 133 drives the arm plate 134 to fit against the outer side of the cylinder 4, so that the arm plate 134 can hug the cylinder 4 tightly, which prepares for the inner partition 5 to enter the cylinder 4.

[0059] Next, place the inner partition 5 on the shelf 7 (see reference). Figure 7 One side of the inner partition 5 contacts the first frame 72, and the other side contacts the limiting end of the quick clamp 74. The outer periphery of the inner partition 5 contacts the side of the second frame 73. At this time, the inner partition 5 is placed.

[0060] Next, the first power mechanism 64 is activated, which drives the horizontal arm 21 on the column slide plate 61 to move vertically on the column 6. After moving to a suitable distance, the first power mechanism 64 is closed. At the same time, the third power mechanism 271 is activated, and the horizontal arm slide plate 27 and the welding device 3 are moved away from the cylinder 4, thereby avoiding positional interference between the welding device 3 and the inner partition 5 during installation. Then, the second power mechanism 611 is activated, and the horizontal arm 21 moves towards the inner partition 5. After moving to a suitable distance, the second power mechanism 611 is closed. At this time, the fourth power mechanism 263 is activated to adjust the position of the support frame 23, so that the suction cup 24 can be opened to adsorb the side of the inner partition 5, completing the position adjustment and adsorption work of the inner partition 5.

[0061] Finally, the quick clamp 74 is opened, the second power mechanism 611 is activated, and the horizontal arm 21 drives the inner partition 5 into the cylinder 4. During this process, the first telescopic mechanism 25 is activated, causing the inner partition 5 to tilt (see reference). Figure 2 Once in position, the first telescopic mechanism 25 is controlled to push the inner partition 5 straight. At this time, the cylinder 4 is supported by the inner partition 5. The third telescopic mechanism 133 is activated again to drive the arm plate 134 away from the cylinder 4. The third power mechanism 271 is activated, and the welding device 3 and the cross arm slide plate 27 enter the cylinder 4. After the laser weld seam tracker 37 senses the weld seam position between the inner partition 5 and the cylinder 4, the welding gun 32 is activated to weld it. During the welding process of the welding gun 32 between the inner partition 5 and the cylinder 4, the sixth power mechanism 10 drives the cylinder 4 to rotate, thereby achieving the welding of one ring of weld seam of the inner partition 5.

[0062] The embodiments described above are merely preferred embodiments of this utility model and are not intended to limit the scope of implementation of this utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the patent claims of this utility model should be included within the scope of the patent application of this utility model.
