[0002] A clamp is a tool used for clamping, fastening or lifting, and is widely used in industries such as metallurgy, transportation, and railways.

[0003] Existing clamps, such as those described in patent application number CN201320727166.4, utilize a suitable method to drive two jaws to rotate relative to each other, thereby gripping the material. Typically, friction between the jaws and the material is used to overcome the material's gravity. To achieve sufficient friction, the pressure exerted by the jaws on the material must be increased. However, when clamping a stack of metal sheets, excessive pressure can easily damage the edges of the sheets.

[0004] Therefore, how to prevent the clamp claws from pinching the edge of the metal plate is a technical problem that needs to be solved urgently. Utility Model Content

[0005] The purpose of the utility model is to overcome the above technical deficiencies and to provide a clamp for stacking metal plates, so as to solve the technical problem in the prior art of how to prevent the clamp claws from clamping the edges of the metal plates.

DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0025] In order to solve the technical problem of preventing the edge of the metal plate from being clamped by the clamp claws 210 , the utility model provides a clamp for a metal plate stack, which can prevent the edge of the metal plate stack from being clamped by the clamp claws 210 .

[0026] It should be noted that the metal sheet stack clamp of the present invention is used for but not limited to lifting metal sheet stacks, etc. For the sake of convenience, in the present invention, only the application of the metal sheet stack clamp in lifting metal sheet stacks is used as an example for explanation. The principle of applying the metal sheet stack clamp to other types of equipment is essentially the same as the principle applied to lifting metal sheet stacks, and will not be elaborated here.

[0027] See also Figure 1 , Figure 1 The present invention is a schematic structural diagram of a clamp for stacking metal sheets according to an embodiment of the present invention. The clamp comprises a base 100, a clamping assembly 200, and two limiting assemblies 300. The clamping assembly 200 comprises two jaws 210 mounted on the base 100, with a jaw opening defined between the two jaws 210. The two jaws 210 are capable of relative movement to adjust the jaw opening size. The two limiting assemblies 300 correspond to the two jaws 210 one-to-one. The limiting assembly 300 comprises a limiting pin 310 and a limiting driver 320. The limiting pin 310 is movably disposed at one end of the jaw 210 away from the base 100. The limiting pin 310 has a first position along its movable trajectory that allows material to enter and exit the jaw opening, and a second position that prevents material from exiting the jaw opening. The limiting driver 320 is in transmission connection with the limiting pin 310 to drive the limiting pin 310 to switch between the first and second positions.

[0028] In this embodiment, the distance between the two jaws 210 is first widened, and the limit pin 310 is adjusted to the first position via the limit driver 320, allowing the stack of metal sheets to enter the jaws. Once the stack of metal sheets has entered the jaws, the limit driver 320 then adjusts the limit pin 310 to the second position, blocking the stack of metal sheets with the limit pin 310, thereby preventing the stack of metal sheets from escaping the jaws. This eliminates the need for the jaws 210 to exert significant clamping pressure on the stack of metal sheets to maintain its stability. This reduced pressure on the stack of metal sheets by the jaws 210 effectively prevents damage to the edges of the metal sheets.

[0029] In some embodiments, the limiting pin 310 is rotatably mounted on the end of the jaw 210 , and the limiting driving member 320 is in transmission connection with the limiting pin 310 to drive the limiting pin 310 to rotate.

[0030] In this embodiment, when the stop pin 310 is in the first position, the stop pin 310 is parallel to the edge of the jaw 210, and the stack of metal sheets can be smoothly inserted into and out of the jaws. When the stop pin 310 is in the second position, the stop pin 310 is perpendicular to the edge of the jaw 210, and the stack of metal sheets can be removed from the jaws.

[0031] Any implementation of the limit driving member 320 that can drive the limit pin 310 to rotate is feasible. In some embodiments, the limit driving member 320 includes a first motor 321, the first motor 321 is installed on the clamp jaw 210, and the output shaft of the first motor 321 is directly connected to the rotating shaft of the limit pin 310.

[0032] In this embodiment, since the output shaft of the first motor 321 is directly connected to the limiting pin 310 , it can drive the limiting pin 310 to rotate.

[0033] On the basis of the above embodiments, in some embodiments, the jaw 210 is provided with a receiving cavity 211 , and the first motor 321 is built into the receiving cavity 211 .

[0034] In some embodiments, the clamping assembly 200 includes a clamping driver 220 , and the jaws 210 are slidably disposed on the base 100 . The clamping driver 220 is transmission-connected to the jaws 210 to drive the two jaws 210 to move relative to each other.

[0035] In this embodiment, the clamping drive 220 drives the two jaws 210 to move relative to each other, thereby changing the size of the jaws.

[0036] Any implementation method that allows the jaws 210 to slide on the base 100 is feasible. In some embodiments, the base 100 is provided with two guide slots 110 corresponding to the two jaws 210 , and the jaws 210 are partially movably disposed through the jaws 210 .

[0037] In this embodiment, under the guidance of the guide groove 110 , the clamp claw 210 can slide along a fixed sliding track, making the sliding track of the clamp claw 210 more stable.

[0038] In some embodiments, the clamping driver 220 is connected to the two jaws 210 to drive the two jaws 210 to move synchronously.

[0039] In this embodiment, the two jaws 210 move synchronously so that the two jaws 210 can be pressed against the side of the metal sheet stack at the same time.

[0040] Based on the above embodiments, in some embodiments, the clamp jaw 210 has a rack 212, and the clamping drive 220 includes a gear 221 and a second motor 222. The gear 221 is engaged with the two racks 212 at the same time, and the second motor 222 drives the gear 221 to rotate.

[0041] In this embodiment, the second motor 222 drives the gear 221 to rotate. Since the rack 212 and the gear 221 are meshed with each other, the rotating gear 221 can drive the two racks 212 to move, thereby causing the jaws 210 to slide relative to the base 100 .

[0042] In some embodiments, the inner side of the jaw 210 has a plurality of teeth 213 .

[0043] In this embodiment, the latch teeth 213 on the inner side of the jaw 210 can increase the friction between the jaw 210 and the stack of metal plates.

[0044] In some embodiments, the base 100 has a connection pad 120 at one end away from the jaw 210 .

[0045] In this embodiment, the connection plate 120 can be used to connect to the lifting equipment.

[0046] In order to better understand the present invention, the following Figures 1 to 2 The technical solution of the utility model is described in detail:

[0047] First, the distance between the two jaws 210 is widened, and the limit pin 310 is adjusted to a first position via the limit drive 320. When the limit pin 310 is in the first position, it is parallel to the edge of the jaw 210, allowing the stack of metal sheets to enter and exit the jaws smoothly. Once the stack of metal sheets has entered the jaws, the limit drive 320 then adjusts the limit pin 310 to a second position. When the limit pin 310 is in the second position, it is perpendicular to the edge of the jaw 210, allowing the stack of metal sheets to exit the jaws. By blocking the stack of metal sheets with the limit pin 310, it prevents them from exiting the jaws, eliminating the need for the jaws 210 to apply significant clamping pressure to maintain the stack. This reduces the pressure exerted by the jaws 210 on the stack of metal sheets, effectively preventing the edges of the metal sheets from being crushed.

[0048] The specific embodiments of the present invention described above do not limit the scope of protection of the present invention. Any other corresponding changes and modifications made based on the technical concept of the present invention should be included in the scope of protection of the claims of the present invention.
