Description

Technical Field

[0001] The utility model relates to the technical field of aluminum coil conveying and transferring equipment, in particular to an automatic clamping type operating device. Background Art

[0002] After the aluminum sheet is rolled into an aluminum coil, it will be longitudinally cut into multiple narrow coils of predetermined width according to actual product needs. After longitudinal cutting, the width of the narrow coil becomes smaller, and the diameter of the narrow coil is equal to the original diameter of the aluminum coil and is in a large diameter state, causing the narrow coil after longitudinal cutting to be very easy to tip over. Therefore, when the narrow coil is transported and transferred by a transport trolley, a slight bump in the transport trolley will cause the center of mass of the narrow coil to exceed the width range of the narrow coil and tip over. Not only will the narrow coil be damaged by falling, but the narrow coil is also heavy and may injure staff when it tips over, causing a major safety hazard.

[0003] In the prior art, in order to transport narrow coils more stably and safely, it is usually necessary to fix the narrow coils, for example, directly support the narrow coils with manpower, or design special tooling to fix the narrow coils. Although the narrow coils can be assisted to be fixed, the manual support method has high labor intensity and still has great safety risks. The method of fixing the narrow coils with special tooling is not only costly, but also has high labor intensity and affects the overall efficiency of the longitudinal cutting of the aluminum coils because each narrow coil needs to be fixed. Therefore, it is necessary to design a device that can conveniently and stably fix the narrow coils so that the narrow coils can be stably and safely transported and transferred. Utility Model Content

[0004] The utility model aims to provide an automatic clamping operation device to solve the problems of poor stability and safety risks in the prior art when narrow rolls are transported and transferred.

[0005] In order to solve the above problems, the utility model adopts the following technical solutions: an automatic clamping operation device, including a support seat, on which two clamping mechanisms are symmetrically arranged, and the clamping mechanisms include a pressure-bearing member, a connecting rod member, a swing member, an elastic connecting member and a clamping member;

[0006] The connecting rod is rotatably connected to the support seat, the pressure bearing member is connected to one end of the connecting rod, the swing member is rotatably connected to the other end of the connecting rod, the pressing member is connected to the end of the swing member away from the connecting rod, and the elastic connecting member is fixedly connected between the swing member and the connecting rod;

[0007] The pressure-bearing part is located below the clamping part. When the clamping part is not subjected to external force, the pressure-bearing part is located above the top surface of the support seat. The distance between the two clamping parts and the distance between the two pressure-bearing parts are both smaller than the diameter of the aluminum coil. The two clamping parts form a clamping gap for clamping the aluminum coil.

[0008] The principle and beneficial effects of this solution are as follows: In this application, the number of clamping mechanisms is two, and the two clamping mechanisms are symmetrically arranged along the support base, so that the two clamping mechanisms can clamp and fix the narrow roll from both sides of the narrow roll, thereby preventing the narrow roll from tipping over during operation. Specifically, the clamping mechanism includes a pressure-bearing member, a connecting rod member, a swinging member, an elastic connecting member, and a clamping member. The connecting rod member is rotatably connected to the support base, and the pressure-bearing member and the swinging member are respectively connected to both ends of the connecting rod member, so that the connecting rod member forms a lever structure.

[0009] In the initial state of use, the clamping member is not affected by external forces. At this time, the distance between the two clamping members in the two clamping mechanisms is less than the diameter of the narrow roll, and the pressure-bearing member is located below the clamping member. When the narrow roll is gradually lowered from above the clamping member or the support base is pushed upward, the narrow roll first comes into contact with the two clamping members at the same time. The clamping member is pushed to both sides of the support base under the gravity of the narrow roll, causing the swinging member to swing relative to the connecting rod member. At this time, the elastic connecting member is stretched and stores energy. Under the pulling force of the elastic connecting member, the clamping member is always in a state of being in contact with the narrow roll during the lowering process of the narrow roll, playing a stabilizing role in the lowering process of the narrow roll.

[0010] When the narrow roll moves to the bottom of the narrow roll and comes into contact with the two pressure-bearing members at the same time, the pressure-bearing member is pushed by the extrusion force of the narrow roll to drive the connecting rod member to rotate. When the connecting rod member rotates, it pushes the end of the swinging member away from the connecting rod member to swing towards the narrow roll, so that the clamping member connected to the swinging member moves towards the narrow roll. Thus, the clamping member always clamps and holds the narrow roll tightly during the movement of the narrow roll, and when the narrow roll is moved to the support base, the clamping member always maintains the state of holding the narrow roll tightly, so that the narrow roll will not easily tip over during the transportation process after being held and fixed, effectively improving the stability and safety during the transportation of the narrow roll.

[0011] In this application, since the entire device is automatically clamped during the movement of the narrow roll and the entire process does not require external force drive and can achieve automatic clamping, the installation process of the narrow roll is very convenient, effectively saving manpower compared with the prior art; more importantly, when the narrow roll is in operation, the clamping member always plays a role of clamping and pressing on the narrow roll, so that the narrow roll is stably placed on the support base, preventing the narrow roll from tipping over during operation. When the narrow roll is transported to the predetermined position, only need to lift the narrow roll upward. Under the extrusion action of the narrow roll on the clamping member, the clamping member can be automatically pushed to open and taken out smoothly, and the operation is very simple and convenient.

[0012] Preferably, as an improvement, the number of connecting rod members in the clamping mechanism is multiple, the number of swinging members is equal to the number of connecting rod members and they are arranged in one-to-one correspondence. An elastic connecting member is fixedly connected between each swinging member and the connecting rod member. The pressure-bearing member is connected to all the connecting rod members at the same time, and the clamping member is connected to all the swinging members.

[0013] In this solution, by setting multiple swinging members and connecting rod members, both the pressure-bearing member and the pressing member can be supported by multiple fulcrums during the movement process, thereby improving the stability of the pressing member and the pressure-bearing member during the movement process.

[0014] Preferably, as an improvement, the pressing member includes a pressing shaft that is rotationally engaged with the swinging member.

[0015] In this solution, the pressing member is a pressing shaft so that the pressing shaft is rotationally connected to the swinging member. And during the movement of the narrow coil, as the narrow coil gradually moves, the outer wall of the pressing shaft will slide relative to the narrow coil while pressing against the narrow coil. Therefore, in this solution, the rotational connection between the pressing shaft and the swinging member can change from relative sliding to relative rolling when the pressing shaft slides relative to the surface of the narrow coil, thereby reducing the damage to the surface of the narrow coil caused by the pressing shaft during the process of pressing against the narrow coil.

[0016] Preferably, as an improvement, a pressing rubber roller is sleeved on the pressing shaft.

[0017] In this solution, the pressing rubber roller is fixedly connected to the pressing shaft, so that the pressing rubber roller contacts the narrow coil during the process of holding the narrow coil. The pressing rubber roller can play a better role in protecting the surface of the narrow coil compared with the pressing shaft; at the same time, the friction between the pressing rubber roller and the narrow coil is greater, so that the narrow coil is less likely to slide along the length direction of the pressing rubber roller and fall, making the operation process of the narrow coil more stable.

[0018] Preferably, as an improvement, the pressure-bearing member includes a pressure-bearing shaft that is rotationally engaged with the connecting rod member.

[0019] In this solution, similar to the shaft structure of the pressing shaft, the pressure-bearing member is a pressure-bearing shaft, and the installation of the pressure-bearing shaft is convenient and can play a role in protecting the surface of the narrow coil.

[0020] Preferably, as an improvement, a pressure-bearing rubber roller is sleeved on the pressure-bearing shaft.

[0021] In this solution, similar to the setting of the pressing rubber roller, it can play a good role in protecting the surface of the narrow coil during the contact and cooperation process between the narrow coil and the pressure-bearing rubber roller.

[0022] Preferably, as an improvement, an inner concave placement groove that cooperates with the narrow coil is opened at the top of the support base, and a receiving groove that cooperates with the pressure-bearing rubber roller is opened on the support base, and the depth of the receiving groove is greater than or equal to the diameter of the pressure-bearing rubber roller.

[0023] In this solution, a concave placement groove and a receiving groove are provided on the top surface of the support base. When the narrow coil moves and presses the pressure-bearing rubber roller into the receiving groove, the narrow coil contacts the concave placement groove. At this time, the support base plays a supporting role for the narrow coil, enabling the narrow coil to be loaded on the support base more stably. At the same time, after setting the receiving groove, it can prevent the pressure-bearing rubber roller from being tightly pressed against the top surface of the support base by the narrow coil, thereby protecting the pressure-bearing rubber roller and enabling the pressure-bearing rubber roller to conduct the force of the narrow coil on the connecting rod more stably.

[0024] Preferably, as an improvement, the tightening mechanism further includes a connecting shaft, and all the swing parts in the tightening mechanism are rotatably connected to the connecting shaft, and all the connecting rod parts in the tightening mechanism are fixedly connected to the connecting shaft.

[0025] In this solution, by setting the connecting shaft, all the connecting rod parts and swing parts are connected by the connecting shaft, making all the swing parts rotate more consistently, so as to stably push the tightening part to tightly press the narrow coil and achieve a more stable clamping effect.

[0026] Preferably, as an improvement, a clearance groove for rotational cooperation with the connecting rod part is formed on the support base.

[0027] In this solution, a clearance groove is formed on the support base, so that the rotation of the support base will not be interfered by the support base, making the structure of the whole device more compact and occupying less space.

[0028] Preferably, as an improvement, a base is provided below the support base, a lifter is provided between the base and the support base, and rollers are rotatably connected to the four sides of the base.

[0029] In this solution, by setting the lifter, after the aluminum coil is longitudinally cut into narrow coils, the lifter is used to push the support base upward, so that all the components on the support base can move upward closer to the narrow coil, thereby automatically tightly pressing and placing the narrow coil on the support base and automatically completing the installation and placement of the narrow coil. In addition, after setting the lifter, there is a certain distance between the support base and the ground, so that the connecting rod parts and swing parts have a larger space for rotation or swing, improving the stability of the device operation. At the same time, rollers are rotatably connected to the four sides of the base. After the narrow coil is placed on the support base, it is convenient to push the device and the narrow coil to move, so as to conveniently transfer the narrow coil to a predetermined position.

[0036] The following is a further detailed description through specific implementation manners:

[0037] Reference numerals in the accompanying drawings of the specification include: support base 1, concave placement groove 101, avoidance groove 102, accommodation groove 103, narrow roll 2, connecting rod seat 3, fixed shaft 4, bearing shaft 5, bearing rubber roller 6, swing seat 7, connecting shaft 8, connecting spring 9, abutting shaft 10, abutting rubber roller 11, base 12, support column 13, roller 14.

[0038] Embodiment 1

[0039] This embodiment is as shown in Figure 1 and Figure 2 : An automatic clamping operation device includes a support base 1. Two abutting mechanisms are symmetrically arranged on the left and right of the support base 1. After the narrow roll 2 is placed on the support base 1, the two abutting mechanisms clamp and fix the narrow roll 2, so as to prevent the narrow roll 2 from tipping during the operation of the narrow roll 2; at the same time, in order to make the narrow roll 2 more stable after being placed on the support base 1, in this embodiment, a concave placement groove 101 is opened on the top surface of the support base 1 along the length direction of the support base 1, and the concave placement groove 101 can provide stable support for the narrow roll 2 and reduce the left and right rolling of the narrow roll 2 during the operation.

[0040] Combined with Figure 1 and Figure 3, in this embodiment, the pressing mechanism includes a pressure-bearing member, a connecting rod member, a swinging member, an elastic connecting member, and a pressing member. The connecting rod member is rotatably connected to the support base 1. The pressure-bearing member is connected to one end of the connecting rod member. The swinging member is rotatably connected to the other end of the connecting rod member. The pressing member is connected to the end of the swinging member away from the connecting rod member. The elastic connecting member is fixedly connected between the swinging member and the connecting rod member. The pressing member is located above the support base 1, and the pressure-bearing member is located between the pressing member and the support base 1. When the pressing member is not subject to external force, the pressure-bearing member is located above the top surface of the support base 1, and the distance between the two pressing members and the distance between the two pressure-bearing members are both smaller than the diameter of the narrow coil 2. The two pressing members form a pressing gap for pressing the narrow coil 2. At the same time, in this embodiment, the number of connecting rod members in each pressing mechanism is multiple, the number of swinging members is equal to the number of connecting rod members and they are arranged in one-to-one correspondence, and the aforementioned elastic connecting member is provided between each swinging member and the connecting rod member. Specifically, in this embodiment, three connecting rod members are provided in each pressing mechanism, and three swinging members and three elastic connecting members are correspondingly provided.

[0041] Taking Figure 3 the pressing mechanism on the left in [description] as an example for illustration, the connecting rod member is a connecting rod seat 3 rotatably connected to the support base 1. The left end of the connecting rod seat 3 is located outside the left side of the support base 1, and the right end of the connecting rod seat 3 is located above the support base 1. In order to enable the connecting rod seat 3 to rotate relative to the support base 1 more smoothly, an avoidance groove 102 for rotational cooperation with the connecting rod seat 3 is provided on the support base 1. At the same time, in order to facilitate the formation of a rotational connection between the connecting rod seat 3 and the support base 1, in this embodiment, a fixed shaft 4 arranged along the length direction of the support base 1 is fixedly connected to the support base 1. The fixed shaft 4 passes through the avoidance groove 102, and all the connecting rod seats 3 are rotatably connected to the fixed shaft 4 through bearings.

[0042] Combined with Figure 1 and Figure 3 , the pressure-bearing member includes a pressure-bearing shaft 5 rotatably connected to the right end of the connecting rod seat 3 through a bearing, and the pressure-bearing shaft 5 is arranged along the length direction of the support base 1 and is rotatably connected to the three connecting rod seats 3 at the same time. In addition, multiple flexible pressure-bearing rubber rollers 6 are sleeved and fixedly connected on the pressure-bearing shaft 5, and a receiving groove 103 for cooperating with the pressure-bearing rubber rollers 6 is opened on the top surface of the support base 1. The depth of the receiving groove 103 is greater than or equal to the diameter of the pressure-bearing rubber rollers 6, so that the pressure-bearing rubber rollers 6 can be completely immersed in the receiving groove 103 without protruding outside the support base 1.

[0043] Such as Figure 1As shown, the swinging member is a swinging seat 7 rotatably connected to the left end of the connecting rod seat 3 through a bearing. At the same time, in order to facilitate the connection of all the swinging seats 7 and the connecting rod seats 3, the pressing mechanism in this embodiment further includes a connecting shaft 8. The left ends of all the connecting rod seats 3 are fixedly connected to the connecting shaft 8, and the bottom ends of all the swinging seats 7 are rotatably connected to the connecting shaft 8 through bearings. The elastic connecting member in this embodiment is a connecting spring 9. The bottom end of the connecting spring 9 is fixed to the side wall of the connecting rod seat 3, and the top end of the connecting spring 9 is fixedly connected to the side wall of the swinging seat 7. The pressing member in this embodiment includes a pressing shaft 10 rotatably connected to the top end of the swinging seat 7 through a bearing. The pressing shaft 10 is arranged along a direction parallel to the bearing shaft 5, and the pressing shaft 10 is rotatably connected to the top ends of three swinging seats 7 at the same time. Multiple pressing rubber rollers 11 are sleeved and fixedly connected to the pressing shaft 10.

[0044] The specific implementation process is as follows:

[0045] In this embodiment, when the bearing rubber roller 6 is not subjected to an external force, the distance between the bearing rubber rollers 6 in the two pressing mechanisms is less than the diameter of the narrow coil 2. And under the supporting force of the connecting spring 9, the swinging seat 7 is in a state of tilting from the top end towards the center direction above the supporting seat 1. The bearing shaft 5 and the bearing rubber roller 6 on the bearing shaft 5 are both located above the supporting seat 1.

[0046] When placing the narrow coil 2, a crane can be used to lift multiple narrow coils 2 simultaneously above the pressing shaft 10 and make all the narrow coils 2 fit together to form a cylindrical shape as a whole. Then, slowly lower the narrow coil 2. When the bottom of the narrow coil 2 touches the pressing rubber roller 11, the pressing rubber roller 11 contacts and presses against the outer surface of the narrow coil 2. Under the gravity of the narrow coil 2, the pressing shaft 10 and the swinging seat 7 are subjected to a squeezing force and swing towards both sides of the supporting seat 1. The distance between the two pressing shafts 10 in the two pressing mechanisms gradually increases, and the connecting spring 9 is also stretched and elongated (i.e., Figure 1 the state shown). As the narrow coil 2 gradually moves, the pressing rubber roller 11 will roll relative to the outer surface of the narrow coil 2 while pressing against the narrow coil 2. By using the pressing action of the pressing rubber roller 11, the narrow coil 2 can move more smoothly.

[0047] After the bottom of the narrow coil 2 moves to contact with the pressure-bearing rubber roller 6, the pressure-bearing rubber roller 6 is subjected to the extrusion force of the narrow coil 2, causing the pressure-bearing rubber roller 6 and the pressure-bearing shaft 5 to be gradually squeezed downward. During this process, the pressure-bearing shaft 5 transmits the pressure received to the connecting rod seat 3, causing the connecting rod seat 3 to rotate relative to the support seat 1. When the connecting rod seat 3 rotates, the end of the connecting rod seat 3 connected to the swing seat 7 rotates upward, causing the swing seat 7 to swing towards the narrow coil 2. During this process, under the pulling force of the connecting spring 9, the top of the swing seat 7 connected to the abutting shaft 10 and the abutting rubber roller 11 always abut against the narrow coil 2, ensuring that the narrow coil 2 is always in a clamped state during movement, effectively improving the stability of the narrow coil 2 during movement.

[0048] After the pressure-bearing rubber roller 6 is completely immersed in the receiving groove 103 (i.e., Figure 4 and Figure 5 the state shown), the bottom of the narrow coil 2 falls into the concave placement groove 101. At this time, the support seat 1 supports the narrow coil 2, and the abutting rubber roller 11 abuts against both sides of the narrow coil 2, playing a role in clamping and fixing the narrow coil 2. Relying on the abutting action of the abutting rubber roller 11 and the limiting action of the concave placement groove 101, the narrow coil 2 is firmly fixed in the concave placement groove 101 and cannot roll left and right. At the same time, when the abutting rubber roller 11 abuts against the narrow coil 2, a very large static friction force will also be generated between the abutting rubber roller 11 and the narrow coil 2, preventing the narrow coil 2 from tipping forward and backward. As a result, the narrow coil 2 is in a stably fixed state during subsequent operation, effectively improving the stability and safety of the narrow coil 2 during operation.

[0049] Embodiment Two

[0050] The difference between Embodiment Two and Embodiment One is that as Figure 6 shown, in this embodiment, a base 12 is provided below the support seat 1. A plurality of elevators 13 are fixedly connected between the base 12 and the support seat 1 by screws, and rollers 14 are rotatably connected around the base 12. In this embodiment, by providing the base 12 and the elevators 13, the elevators 13 can adopt power structures such as hydraulic cylinders. Since there is a certain height between the support seat 1 and the ground in this embodiment, sufficient movement space is provided for the swing or rotation of the connecting rod seat 3 and the swing seat 7, making the operation of the device more stable. At the same time, after the aluminum coil is longitudinally cut into narrow coils, the elevators 13 can be used to push the support seat 1 upward, causing all the components on the support seat 1 to move upward and approach the narrow coil 2 until the narrow coil 2 is automatically installed and placed, making the operation more convenient. In addition, by providing the rollers 14 on the base 12, after the narrow coil 2 is installed and placed in the concave placement groove 101, the base 12 can be conveniently pushed to transfer the narrow coil 2 to other workstations, making it more convenient to use.

[0051] Embodiment Three

[0052] The difference between the third embodiment and the first embodiment is as follows: in the first embodiment, the pressure-bearing rubber roller 6 is fixed on the pressure-bearing shaft 5, and the pressing rubber roller 11 is fixedly connected to the pressing shaft 10. In this embodiment, in order to further enhance the protection effect on the surface of the narrow coil 2 and reduce the possible frictional damage during the lowering process of the narrow coil 2, the pressure-bearing rubber roller 6 is rotatably connected to the pressure-bearing shaft 5, and at the same time, the pressing rubber roller 11 is rotatably connected to the pressing shaft 10.

[0053] The above are only the embodiments of the present invention. Specific technical solutions and / or common knowledge such as characteristics well known in the art are not described in detail herein. It should be noted that for those skilled in the art, without departing from the technical solution of the present invention, several modifications and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the implementation effect of the present invention and the practicability of the patent. The protection scope required by this application shall be subject to the content of its claims, and the specific implementation manners described in the specification can be used to interpret the content of the claims.
