Description

Technical Field

[0001] The utility model relates to the field of lifting equipment, in particular to a fixture for steel coil turnover and a robotic arm. Background Art

[0002] A steel coil, also known as a rolled steel, is formed into a coil shape by hot pressing and cold pressing of steel, which is convenient for storage, transportation and various processing.

[0003] At present, a steel coil is usually clamped by a steel coil clamp. For the existing steel coil clamp, reference can be made to the patent with the application number CN201610760283.9. It is necessary to extend a part of the steel coil clamp into the steel coil to smoothly move the steel coil. In order to avoid damage to the steel coil, a horizontal placement method is usually adopted during the storage and transportation of the steel coil. However, in some usage scenarios of the steel coil, it is necessary to turn the steel coil into a vertical placement. However, the existing clamp needs to extend a part into the interior of the steel coil. Once the steel coil is turned into a vertical placement, it is extremely difficult for the steel coil clamp to disengage from the steel coil, making the turnover work of the steel coil extremely difficult.

[0004] Therefore, how to turn a horizontally placed steel coil into a vertically placed one is a technical problem to be solved urgently. Summary of the Utility Model

[0005] The purpose of the utility model is to overcome the above technical deficiencies and provide a fixture for steel coil turnover to solve the technical problem of how to turn over a steel coil in the prior art.

[0006] To achieve the above technical purpose, the utility model adopts the following technical solutions:

[0007] The utility model provides a fixture for steel coil turnover, which includes:

[0008] An inner support assembly, which includes a support tray and a support column. One end of the support column is connected to the support tray, and the support column penetrates through the steel coil; and

[0009] A clamping assembly, which includes a base, a first clamp and a second clamp. The first clamp and the second clamp are both installed on the base. The first clamp is used to clamp the support tray in the radial direction, and the second clamp is used to clamp one end of the support column away from the support tray in the radial direction.

[0010] In some embodiments, a first annular groove is formed on the outer periphery of the support tray. When the first clamp clamps the support tray, a part of the first clamp is embedded in the first annular groove. A second annular groove is formed on the outer periphery of the support column. When the second clamp clamps the support column, a part of the second clamp is embedded in the second annular groove.

[0011] In some embodiments, the support bracket includes a base and a rotating seat, the rotating seat is rotatably mounted on the base, and the support column is connected to the base.

[0012] In some embodiments, the support column is coaxially arranged with the base.

[0013] In some embodiments, the base is provided with a mounting hole, the rotating seat has a rotating shaft, and the rotating shaft passes through the mounting hole so that the rotating seat rotates relative to the base.

[0014] In some embodiments, the inner support assembly further includes a bearing, the inner ring of the bearing is sleeved on the outer periphery of the rotating shaft, and the outer ring of the bearing is embedded in the mounting hole.

[0015] In some embodiments, a nylon pad is attached to the contact surface between the rotating seat and the steel coil.

[0016] In some embodiments, the base has a connecting disc.

[0017] In some embodiments, the base is provided with a first mounting groove and a second mounting groove, and the first clamp and the second clamp are respectively embedded in the first mounting groove and the second mounting groove.

[0018] A robotic arm includes the above-mentioned fixture for flipping a steel coil.

[0019] First, the support column penetrates through the steel coil, and the support bracket presses against one end of the steel coil. Subsequently, the first clamp is used to clamp the support bracket radially, and the second clamp is used to clamp the support column radially, so that the steel coil can be clamped. At this time, flipping the base can drive the steel coil to flip, and then placing the support bracket on the ground can adjust the steel coil to a vertical position. Finally, separating the first clamp and the second clamp from the support column and the support bracket respectively can complete the flipping work of the steel coil. Since the first clamp and the second clamp do not need to extend into the inner ring of the steel coil, when the steel coil is converted to a vertical position, the first clamp and the second clamp can be separated from the steel coil smoothly, making the flipping work of the steel coil convenient and efficient.

Detailed Description of the Embodiments

[0022] In order to make the purpose, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0023] In order to solve the technical problem of how to turn a horizontally placed steel coil into a vertically placed one, the present utility model provides a fixture for turning a steel coil. Since the clamp does not need to extend into the interior of the steel coil, after the steel coil is converted into a vertical placement, the clamp can still be smoothly disengaged from the steel coil, making the turning work of the steel coil convenient and efficient.

[0024] It should be noted that the fixture for turning a steel coil of the present utility model is used for but not limited to steel coil lifting equipment, etc. For the convenience of description, in the present utility model, only the case where the fixture for turning a steel coil is applied to a steel coil lifting equipment is taken as an example for description, and the principle of applying the fixture for turning a steel coil to other types of equipment is essentially the same as that applied to the steel coil lifting equipment, and will not be elaborated one by one here.

[0025] Please refer to Figure 1 , Figure 1 , which is a schematic structural diagram of a fixture for turning a steel coil in an embodiment of the present utility model. The fixture for turning a steel coil includes an inner support assembly 100 and a clamping assembly 200. The inner support assembly 100 includes a support tray 110 and a support column 120. One end of the support column 120 is connected to the support tray 110, and the support column 120 penetrates through the steel coil. The clamping assembly 200 includes a base 210, a first clamp 220 and a second clamp 230. The first clamp 220 and the second clamp 230 are both installed on the base 210. The first clamp 220 is used to clamp the support tray 110 in the radial direction, and the second clamp 230 is used to clamp the end of the support column 120 away from the support tray 110 in the radial direction.

[0026] First, the support column 120 is penetrated through the steel coil, and the support tray 110 is pressed against one end of the steel coil. Subsequently, the first clamp 220 is used to clamp the support tray 110 in the radial direction, and the second clamp 230 is used to clamp the support column 120 in the radial direction, so that the steel coil can be clamped. At this time, flipping the base 210 can drive the steel coil to flip, and then placing the support tray 110 on the ground can adjust the steel coil to a vertical placement. Finally, by disengaging the first clamp 220 and the second clamp 230 from the support column 120 and the support tray respectively, the turning work of the steel coil can be completed. Since the first clamp 220 and the second clamp 230 do not need to extend into the inner ring of the steel coil, after the steel coil is converted into a vertical placement, the first clamp 220 and the second clamp 230 can be smoothly disengaged from the steel coil, making the turning work of the steel coil convenient and efficient.

[0027] In some of these embodiments, a first annular groove 1111 is formed on the outer periphery of the support bracket 110. When the first clamp 220 clamps the support bracket 110, a part of the first clamp 220 is embedded in the first annular groove 1111. A second annular groove 121 is formed on the outer periphery of the support column 120. When the second clamp 230 clamps the support column 120, a part of the second clamp 230 is embedded in the second annular groove 121.

[0028] In this embodiment, since a part of the first clamp 220 is embedded in the first annular groove 1111 and a part of the second clamp 230 is embedded in the second annular groove 121, it can effectively prevent the first clamp 220 from sliding axially relative to the support bracket 110, and can also effectively prevent the second jaw from sliding axially relative to the support column 120, so that the first clamp 220 and the second clamp 230 can clamp the support bracket 110 and the support column more stably.

[0029] In some of these embodiments, the support bracket 110 includes a base 111 and a rotating seat 112. The rotating seat 112 is rotatably mounted on the base 111, and the support column 120 is connected to the base 111.

[0030] In this embodiment, the base 111 is fixed to the ground, and the rotating seat 112 is in direct contact with the support column and the steel coil, so that the rotating seat 112 can rotate with the steel coil.

[0031] Based on the above embodiments, in some of these embodiments, the support column 120 is coaxially arranged with the base 111.

[0032] As long as the implementation mode that can make the rotating seat 112 rotate relative to the base 111 is feasible. In some of these embodiments, the base 111 is provided with a mounting hole 1112, and the rotating seat 112 has a rotating shaft 1121. The rotating shaft 1121 passes through the mounting hole 1112 to make the rotating seat 112 rotate relative to the base 111.

[0033] In this embodiment, the rotating shaft 1121 is passed through the mounting hole 1112, so that the rotating seat 112 rotates relative to the base 111.

[0034] Based on the above embodiments, in some of these embodiments, the inner support assembly 100 further includes a bearing 113. The inner ring of the bearing 113 is sleeved on the outer periphery of the rotating shaft 1121, and the outer ring of the bearing 113 is embedded in the mounting hole 1112.

[0035] In this embodiment, since the inner ring of the bearing 113 is sleeved on the outer periphery of the rotating shaft 1121 and the outer ring of the bearing 113 is embedded in the mounting hole 1112, the friction between the rotating shaft 1121 and the inner wall of the mounting hole 1112 can be reduced.

[0036] In some of these embodiments, a nylon pad is attached to the contact surface between the rotating seat 112 and the steel coil.

[0037] In this embodiment, since the nylon pad has a relatively small hardness, when the end face of the steel coil contacts the nylon pad, it can prevent the end of the steel coil from being scratched.

[0038] In some embodiments, the base 210 has a connecting disc 211.

[0039] In this embodiment, the connecting disc 211 is used to connect with the robotic arm so as to drive the base 210 to move through the robotic arm.

[0040] In some embodiments, the base 210 is provided with a first installation groove 212 and a second installation groove 213, and the first clamp 220 and the second clamp 230 are respectively embedded in the first installation groove 212 and the second installation groove 213.

[0041] In this embodiment, the first clamp 220 and the second clamp 230 are respectively embedded in the first installation groove 212 and the second installation groove 213, so that the first clamp 220 and the second clamp 230 can be stably installed on the base 210.

[0042] In addition, the present utility model further provides a robotic arm, which includes the fixture for flipping the steel coil as described above.

[0043] For a better understanding of the present utility model, the following will Figure 1 describe the technical solution of the present utility model in detail:

[0044] First, the support column 120 penetrates through the steel coil, and the support bracket 110 presses against one end of the steel coil. Subsequently, the first clamp 220 is used to clamp the support bracket 110 in the radial direction, and the second clamp 230 is used to clamp the support column 120 in the radial direction, so as to clamp the steel coil. Since a part of the first clamp 220 is embedded in the first annular groove 1111 and a part of the second clamp 230 is embedded in the second annular groove 121, it can effectively prevent the first clamp 220 from sliding axially relative to the support bracket 110, and can also effectively prevent the second clamp from sliding axially relative to the support column 120. At this time, flipping the base 210 can drive the steel coil to flip. Subsequently, placing the support bracket 110 on the ground can adjust the steel coil to a vertical position. Finally, separating the first clamp 220 and the second clamp 230 from the support column 120 and the support bracket respectively can complete the flipping work of the steel coil. Since the first clamp 220 and the second clamp 230 do not need to extend into the inner circle of the steel coil, after the steel coil is converted to a vertical position, the first clamp 220 and the second clamp 230 can be smoothly separated from the steel coil, making the flipping work of the steel coil convenient and efficient.

[0045] The above specific embodiments of the present utility model do not constitute a limitation on the protection scope of the present utility model. Any other corresponding changes and deformations made according to the technical concept of the present utility model should be included in the protection scope of the claims of the present utility model.
