Description

Technical Field

[0001] This utility model belongs to the field of metal processing technology and relates to a nickel strip butt welding clamping fixture. Background Technology

[0002] Nickel strip conductors are a commonly used metal material in the battery industry. Through smelting and forging, metal ingots are formed into coils for subsequent processing. Typically, when nickel strips are processed on the production line, segments of the strips need to be butt-welded to facilitate forging into coils. When butt-welding two nickel strips, the ends must be aligned and pressed tightly to prevent misalignment. During butt-welding, the alignment and pressing are usually done manually. In practice, uneven ends and insufficient pressing inevitably occur, leading to misalignment and connection errors. Summary of the Invention

A transmission plate, one end of which is provided with a connecting block that can cooperate with a hinge seat; the other end of the transmission plate is provided with a hinge plate, which is hinged to the piston rod of the pressing cylinder by a first connecting member; a connecting plate is provided at the lower end of the transmission plate. A pressure plate is provided on the top of which a hinge plate is provided to cooperate with a connecting plate. The hinge plate and the connecting plate are hinged together by a second connector.

[0005] Preferably, the outer side of the pressing cylinder is provided with a connecting flange for fixing to the support frame.

[0006] Preferably, rollers are provided at the four lower corners of the frame.

[0007] Preferably, a counterweight is provided at one end of the pressure plate near the limiting baffle.

[0008] Preferably, the upper end of the support frame is provided with a transverse support plate, and the transverse support plate is provided with a connection hole that can mate with the connection flange.

[0009] Compared with the prior art, this utility model has the following advantages: This invention uses a cylinder as a power source and a transmission plate to drive a pressure plate to press the nickel strips to be welded. Operation is simple, requiring no manual force and preventing insufficient pressing. Limiting baffles on the frame ensure the nickel strips are correctly positioned during connection, preventing uneven ends and welding misalignment. This invention features a simple structure, ingenious design, saves manpower and resources, and is highly practical. Attached Figure Description

[0013] To enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0014] This embodiment proposes a nickel strip butt welding clamping fixture, including a frame 1, a transmission plate 6 and a pressure plate 11. The frame 1 provides installation space for each component, and the transmission plate 6 transmits power to the pressure plate 11. like Figures 1-2 As shown, a support frame 2 is provided at one end of the frame 1, and a pressing cylinder 3 is symmetrically arranged on the support frame 2; a hinge seat 4 corresponding to the position of the pressing cylinder 3 is symmetrically arranged at the other end of the frame 1; a limit baffle 5 is provided in the middle of the frame 1, which is used to align the sides when welding nickel strips to avoid unevenness at the welding ends of the nickel strips. One end of the transmission plate 6 is provided with a connecting block 7 that can cooperate with the hinge seat 4; the other end of the transmission plate 6 is provided with a hinge plate 8. The hinge plate 8 is hinged to the piston rod of the pressing cylinder 3 by means of the first connecting piece 9. When the piston rod of the pressing cylinder 3 moves, it can drive one end of the transmission plate 6 to swing up and down. A connecting plate 10 is provided at the lower end of the transmission plate 6; The pressure plate 11 is provided with a hinge plate 12 that can cooperate with the connecting plate 10. The hinge plate 12 and the connecting plate 10 are hinged by the second connecting member 13. When the transmission plate 6 swings, it can drive the pressure plate 11 to move up and down. The pressure plate 11 is only hinged to the connecting plate 10 through the second connecting member 13, which has a high degree of freedom of movement and will not cause the nickel strip to be clamped on one side and not clamped on the other side. The first connector 9 and the second connector 13 can be connected with bolts, making installation convenient and quick.

[0015] Furthermore, a connecting flange 14 for fixing to the support frame 2 is provided on the outer side of the pressing cylinder 3, which facilitates the connection and fixing of the pressing cylinder 3 and the support frame 2.

[0016] Furthermore, rollers 15 are respectively provided at the four lower corners of the frame 1, which facilitates the movement of the device.

[0017] Furthermore, a counterweight 16 is provided at one end of the pressure plate 11 near the limiting baffle 5. The counterweight 16 causes one end of the pressure plate 11 to hang down naturally and the other end to rise naturally, which facilitates the placement of the nickel strip.

[0018] Furthermore, a transverse support plate 17 is provided at the upper end of the support frame 2, and the transverse support plate 17 is provided with a connection hole 18 that can cooperate with the connection flange 14.

[0019] Working principle: When using this utility model, firstly, the piston rod of the pressing cylinder 3 is retracted, one end of the pressure plate 11 is raised, and the other end of the pressure plate 11 naturally droops due to the counterweight 16; then, the two nickel strips to be welded are placed under the pressure plate 11, and the same side of the two nickel strips is pressed against the limiting baffle 5. Air is supplied to the pressing cylinder 3, and the piston rod of the pressing cylinder 3 drives the pressure plate 11 to move through the transmission plate 6. The pressure plate 11 presses down and presses the nickel strips tightly.

[0020] It is understood that the above embodiments are merely exemplary models used to illustrate the principles of this utility model, and this utility model is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of this utility model, and these modifications and improvements are also considered to be within the protection scope of this utility model.
