Description

Technical Field

[0001] This utility model relates to the field of crimping device technology, and in particular to a crimping device for power engineering cables. Background Technology

[0002] Cable crimping devices for power engineering are specialized tools used to electrically connect cables to terminals (such as lugs and clamps) through crimping. Their core function is to apply mechanical pressure to tightly bond the cable conductor to the terminal, forming a low-resistance, high-mechanical-strength connection. Broadly speaking, wire crimping pliers are a common form of this type of device.

[0003] In the existing technology, when using crimping pliers to crimp power cables, the connection is squeezed only by the upper and lower dies, which cannot squeeze the connection from multiple directions. At the same time, when the cable diameter is different, the dies need to be changed, which is quite troublesome. Therefore, it is necessary to propose a power engineering cable crimping device to solve the above problems. Summary of the Invention

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a power engineering cable crimping device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A power engineering cable crimping device includes a support plate, a rotating disk movably sleeved on the outer circular wall of the support plate, and a crimping assembly for crimping cables. The crimping assembly is disposed on the outer circular wall of the support plate and includes a plurality of cross-shaped limiting holes, all of which are formed on the outer circular wall of the support plate. A cross-shaped wire crimping head is movably sleeved inside the cross-shaped limiting holes. A first fixing post is fixedly installed on one side of the cross-shaped wire crimping head. A plurality of arc-shaped holes are formed on one side of the rotating disk, and the first fixing post is inserted into the arc-shaped holes.

[0006] As a further embodiment of this utility model, the crimping wire assembly further includes: a fixing plate, the fixing plate being fixedly installed on the outer circular wall of the rotating disk, a second fixing column being fixedly installed on one side of the support disk and one side of the fixing plate respectively, and a double-eared hydraulic cylinder being provided on one side of the support disk, the ear ring of the double-eared hydraulic cylinder being rotatably connected to the second fixing column.

[0007] As a further embodiment of this invention, a limiting plate is provided on one side of the rotating disk.

[0008] As a further embodiment of this utility model, a plurality of fixing holes are provided on one side of the limiting plate, and a plurality of threaded grooves are provided on one side of the supporting plate. Bolts are movably sleeved on the inner circular wall of the fixing holes, and the bolts are threadedly connected to the threaded grooves.

[0009] As a further embodiment of this utility model, a reinforcing ring and several reinforcing ribs are provided on one side of the limiting plate, and the reinforcing ring, the limiting plate and the reinforcing ribs are integrally formed.

[0010] As a further embodiment of this utility model, two support feet are fixedly installed on the bottom surface of the support plate.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. By using the support plate, rotating plate, cross-shaped limiting hole, cross-shaped crimping head, and arc-shaped hole in combination, the cable and terminal of the power project can be crimped. The rotating plate and arc-shaped hole allow the cross-shaped crimping head to extend and retract simultaneously to crimp cables of different diameters without the need to replace the crimping head, making it convenient and practical.

[0012] 2. The limiting plate can be removed by loosening the bolts from the threaded groove and fixing hole for easy maintenance. At the same time, the limiting plate is structurally reinforced by reinforcing rings and reinforcing ribs to improve its lateral bending resistance. Attached Figure Description

[0018] Reference Figures 1-9 A power engineering cable crimping device includes: a support plate 1, a rotating disk 2 movably sleeved on the outer circular wall of the support plate 1, and a crimping assembly for crimping cables. The crimping assembly is disposed on the outer circular wall of the support plate 1 and includes: a plurality of cross-shaped limiting holes 3, all of which are opened on the outer circular wall of the support plate 1. A cross-shaped wire crimping head 4 is movably sleeved inside the cross-shaped limiting holes 3. A first fixing post 6 is fixedly installed on one side of the cross-shaped wire crimping head 4. A plurality of arc-shaped holes 5 are opened on one side of the rotating disk 2, and the first fixing post 6 is inserted into the arc-shaped holes 5.

[0019] In this embodiment, the crimping wire assembly further includes: a fixing plate 7, which is fixedly installed on the outer circular wall of the rotating disk 2; a second fixing post 9 is fixedly installed on one side of the support disk body 1 and one side of the fixing plate 7 respectively; a double-eared hydraulic cylinder 8 is provided on one side of the support disk body 1, and the ear ring of the double-eared hydraulic cylinder 8 is rotatably connected to the second fixing post 9; a limiting disk 10 is provided on one side of the rotating disk 2, and a plurality of fixing holes 11 are opened on one side of the limiting disk 10; a plurality of threaded grooves 13 are opened on one side of the support disk body 1; a bolt 12 is movably sleeved on the inner circular wall of the fixing hole 11, and the bolt 12 is threadedly connected to the threaded groove 13; a reinforcing ring 14 and a plurality of reinforcing ribs 15 are provided on one side of the limiting disk 10, and the reinforcing ring 14, the limiting disk 10 and the reinforcing ribs 15 are integrally formed; and two supporting feet 16 are fixedly installed on the bottom surface of the support disk body 1.

[0020] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects: By setting up a support plate 1, when users are performing electrical construction and need to connect power cables and terminals such as lugs and clamps, the double-ear hydraulic cylinder 8 is activated to retract and pull the fixing plate 7, causing the rotating plate 2 to rotate outside the support plate 1. The rotating plate 2 drives several arc-shaped holes 5 to push the first fixing column 6, causing the cross-shaped wire crimping head 4 to move inside the cross-shaped limiting hole 3. This causes the cross-shaped wire crimping head 4 to retract and enter the cross-shaped limiting hole 3, thus allowing the cable and terminal to pass through the inside of the support plate 1, so that the part to be crimped is at the crimping center of the cross-shaped wire crimping head 4. Then, the double-ear hydraulic cylinder 8 is activated to push the fixing plate 7, causing the rotating plate 2 to rotate in the opposite direction, causing the several arc-shaped holes 5 to push the cross-shaped wire crimping head 4 to move towards each other, crimping the cable and terminal connection position. There are eight crimping points in total, which effectively ensures the crimping effect. After crimping, if the cable diameter is large, it can be rotated at a certain angle and crimping can continue, making it suitable for cables and terminals of different diameters.

[0021] Meanwhile, by loosening the bolt 12, the limiting plate 10 can be removed from the threaded groove 13 and the fixing hole 11 for easy maintenance. At the same time, the limiting plate 10 is structurally reinforced by the reinforcing ring 14 and the reinforcing rib 15 to improve its lateral bending resistance, which is quite practical.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
