Detailed Implementation

[0032] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0033] Figures 1-5 The diagram shown is a structural schematic of one embodiment of the power crimping device of this utility model. Please refer to [link / reference]. Figures 1-5 This utility model discloses a crimping device for power applications, the main body of which includes a crimping assembly 100, a wire feeding assembly 200, and a wire insertion assembly 300.

[0034] The crimping assembly 100 includes a workbench 110, support legs 120 symmetrically welded and fixed to the bottom of the workbench 110, a lower module 130 welded and fixed to the middle of the top of the workbench 110, the function of the lower module 130 is to cooperate with the pressing plate 180 to press the wire end and the crimping tube 150 together, a crimping groove 140 opened on the lower module 130, a crimping tube 150 placed in the crimping groove 140, a gantry frame 160 welded and fixed to the lower module 130, the gantry frame 160 is for the convenient installation of the hydraulic cylinder 170, the hydraulic cylinder 170 is fixed to the top of the gantry frame 160 by bolts, and the pressing plate 180 welded and fixed to the bottom of the hydraulic cylinder 170 and adapted to the crimping groove 140. The crimping tube 150 is a sleeve structure made of conductive metal.

[0035] The wire feeding assembly 200, mounted on the workbench 110, can simultaneously feed two wires from both sides to the side of the lower module 130. The wire feeding assembly 200 includes first mounting slots 210 symmetrically formed on the workbench 110. The first mounting slots 210 facilitate the installation of the threaded rods 220. The threaded rods 220, rotatably mounted on the first mounting slots 210, can simultaneously drive the movement of two first moving plates 230 meshing with them. The assembly is fixed to the workbench 110 by bolts. The first motor 220a is coaxially connected to the positive and negative threaded rod 220 on the outer wall, the first moving plate 230 is inserted into the first mounting groove 210 and meshes with the positive and negative threaded rod 220, and the wire mounting plate 240 is welded and fixed to the top of the first moving plate 230. When the negative threaded rod 220 rotates, the first moving plate 230 will carry the wire mounting plate 240 to move, which will drive the wire to move synchronously. A wire placement groove 250 is opened at the top of the wire mounting plate 240, and the part of the wire placed in the wire placement groove 250 can be kept horizontal.

[0036] The wire insertion assembly 300, mounted on the wire feeding assembly 200, allows the end of the wire to be inserted into the inner cavity of the crimping tube 150. The wire insertion assembly 300 includes a second mounting groove 310 formed on the side wall of the wire mounting plate 240, a threaded rod 320 rotatably mounted on the second mounting groove 310, and a second motor 330 bolted to the outer wall of the wire mounting plate 240 and coaxially connected to the threaded rod 320. This design allows the rotating threaded rod 320 to drive the second movable plate 340 to move and insert the wire. The second moving plate 340, which is located in the second mounting groove 310 and meshes with the threaded rod 320, and the L-shaped frame 350, which is welded and fixed on the second moving plate 340, will rotate when the threaded rod 320 is driven by the second motor 330, thereby driving the second moving plate 340 to move. The cylinder 360, which is fixed to the L-shaped frame 350 by bolts, and the pneumatic clamp 370, which is fixed to the bottom of the cylinder 360 by threads, can clamp the wire. In conjunction with the moving L-shaped frame 350, the wire can be moved.

[0037] Furthermore, to make the pressing plate 180 more stable during movement, specifically, the top of the gantry frame 160 is symmetrically provided with limiting holes 190, and a limiting rod 190a is inserted into the limiting hole 190. The limiting rod 190a is fixed on the top surface of the pressing plate 180, so that the limiting rod 190a is always inserted in the limiting hole 190 during the lifting and lowering process of the pressing plate 180, which can prevent the pressing plate 180 from tilting.

[0038] Meanwhile, in order for the wire to be successfully inserted into the crimping tube 150, specifically, the lower module 130 has symmetrically provided docking grooves 130a on its side wall. The side wall of the wire mounting plate 240 is adapted to the docking groove 130a. The wire placement groove 250 and the crimping groove 140 are coaxial and have the same diameter. The wire mounting plate 240 moves and inserts into the docking groove 130a, so that the wire placement groove 250 aligns with the crimping groove 140, making it convenient for the wire to enter the crimping tube 150 along the wire placement groove 250 and the crimping groove 140.

[0039] Finally, to prevent the wire from tilting, a support rod 110a is symmetrically fixed to the top surface of the workbench 110. A limiting arc plate 110b is fixed to the top of the support rod 110a. The arc groove on the top surface of the limiting arc plate 110b matches the arc groove of the crimping groove 140. The operator first places the wire on the limiting arc plate 110b and the wire placement groove 250, so that the wire can always be located in the wire placement groove 250.

[0040] Combination Figures 1-5 The specific implementation of this power crimping device is as follows:

[0041] 1. First, the operator places the wire on the limiting arc plate 110b and the wire placement slot 250. Then, the cylinder 360 drives the pneumatic clamp 370 to descend. The pneumatic clamp 370 starts to clamp the wire, so that the pneumatic clamp 370 can fix the wire. Then, the first motor 220a starts to drive the first moving plate 230 to move, so that the wire moves along with it until the wire mounting plate 240 abuts against the side wall of the lower module 130.

[0042] 2. Then the second motor 330 starts and drives the L-shaped frame 350 to move, so that the pneumatic clamp 370 drives the wire to slide and move, so that the wire enters the crimping groove 140. Then the pneumatic clamp 370 releases the wire, the second motor 330 drives the L-shaped frame 350 to move backward, and then the pneumatic clamp 370 clamps the wire again at a slightly later position. Then the L-shaped frame 350 moves forward again, so that the pneumatic clamp 370 drives the wire to slide and move for the second time, so that the end of the wire enters the crimping tube 150.

[0043] 3. Finally, the hydraulic cylinder 170 is activated to drive the pressing plate 180 to move downward, so that the pressing plate 180 squeezes the crimping tube 150 and the wire. After the crimping tube 150 of the metal sleeve is deformed, it firmly wraps the ends of the two wires, so that the ends of the two wires are tightly connected and the crimping is completed.

[0044] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects. The scope of this utility model is defined by the appended claims rather than the foregoing description, and thus all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this utility model. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0045] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
