DETAILED DESCRIPTION
[0023] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.
[0024] The specific embodiments are given below.
[0025] Please refer to Figures 1 to 5As shown in the figure, a lamp wiring harness crimping mold according to an embodiment of the present invention includes a support base 1, the top of which is provided with a terminal 19; a sliding plate 12 is slidably connected to the middle of the support base 1; a screw 13 is rotatably connected to the middle of the support base 1; the screw 13 and the sliding plate 12 are threadedly connected; a fixing frame 14 is fixedly connected to the top of the sliding plate 12; a fixing rod 15 is fixedly connected to the inner side wall of the fixing frame 14; a pair of pressure plates 16 are symmetrically slidably connected to the middle of the fixing rod 15; a first spring 18 is fixedly connected between the pair of pressure plates 16; a clamping plate 17 is fixedly connected to the end of the pressure plate 16; during operation, the operator can press the pair of pressure plates 16 to bring them closer together, at which time the clamping plate 17 will move with the pressure plates 16 and move away from each other. The first spring 18 is also in a compressed state. After the wire passes through the fixing frame 14, the pressure plate 16 can be released, so that the clamping plate 17 resets and clamps and fixes the wire insulation. Then, the screw 13 can be rotated so that the slide plate 12 drives the fixing frame 14 and the wire to approach the terminal 19 until the wire harness enters the terminal 19. Finally, the wire harness and the terminal 19 can be crimped by the cylinder. Pressing the pressure plate 16 can make the clamping plate 17 quickly fix the wire, improve the convenience of fixing the wire, and improve the stability of the wire crimping. At the same time, the screw 13 transmits the wire on the surface of the slide plate 12, improving the accuracy of the operator's control over the distance of the wire harness entering the terminal 19, and also improving the quality of the wire and terminal 19 crimping.
[0026] Please see Figure 3 and Figure 4 As shown, a magnet 2 is fixedly connected to the end of the pressure plate 16; a pair of magnets 2 are correspondingly arranged; when the worker clamps the wire, the pair of pressure plates 16 need to be squeezed together to bring them closer together. When the pressure plate 16 moves, it will bring the pair of magnets 2 closer together until the pair of magnets 2 are close to each other and attract each other. At this time, the pressure plates 16 will stick together under the magnetic force of the magnets 2, so that the clamping plate 17 will be in the open state. After the wire passes through the fixing frame 14, the worker can forcefully separate the pair of pressure plates 16, so that the clamping plate 17 will fix the insulation part of the wire; by setting the magnets 2, the pressure plate 16 can be stably kept in the open state under the magnetic force of the pair of magnets 2 when the worker fixes the wire, reducing the workload required for the worker to control the pressure plate 16.
[0027] Please see Figure 4 As shown, a protective pad 3 is fixed to the inner wall of the clamp 17; the surface of the protective pad 3 is an arc-shaped structure; when the clamp 17 comes into contact with the wire, the protective pad 3 will also come into contact with the wire. Because the protective pad 3 is made of flexible material and has an arc-shaped surface, when the protective pad 3 comes into contact with the wire, it will disperse the pressure on the surface of the wire, reduce the squeezing effect of the clamp 17 on the surface of the wire, and reduce the damage to the wire caused by excessive squeezing of the clamp 17.
[0028] Please refer to Figure 1 and Figure 5 As shown in the figure, the top of the sliding plate 12 is fixedly connected with a guide plate 4; the guide plate 4 is a circular truncated cone structure; the guide plate 4 and the fixed frame 14 are concentrically arranged; before the wire passes through the fixed frame 14, the wire will pass through the guide plate 4 and come out from the inside of the guide plate 4. Because the guide plate 4 is a circular truncated cone structure, when the wire moves, it will move along the inner wall of the guide plate 4 and come out from the end of the guide plate 4. Finally, the guide plate 4 will reach the central area of the fixed frame 14 and be fixed by the clamping plate 17, improving the accuracy of the position of the wire during feeding and realizing the guidance of the device to the wire.
[0029] Please refer to Figure 5 As shown in the figure, the inner side wall of the guide plate 4 is throughly arranged and slidingly connected with a plurality of sliding rods 5; the end of the sliding rod 5 is fixedly connected with a connecting frame 52; the inner side wall of the connecting frame 52 is rotationally connected with a pulley 53; the end of the sliding rod 5 and the guide plate 4 are fixedly connected with a second spring 54; when the wire passes through the guide plate 4, it will pass through the pulley 53. After the pulley 53 is extruded by the wire, the sliding rod 5 will slide along the guide plate 4 and make the second spring 54 in a stretched state. When the wire is transported, the pulley 53 will rotate, reducing the contact and friction between the wire and the inner wall of the guide plate 4 during feeding.
[0030] Please refer to Figure 5 As shown in the figure, the end of the guide plate 4 is fixedly connected with a sponge 6; the sponge 6 is located between the guide plate 4 and the fixed frame 14; when the wire comes out from the end of the guide plate 4, the surface of the wire will contact the sponge 6, and the sponge 6 will clean the surface of the wire, realizing the cleaning of the device to the surface of the wire and improving the cleanliness of the surface of the wire.
[0031] Please refer to Figure 5 As shown in the figure, the surface of the sponge 6 is an arc structure; because the surface of the sponge 6 is an arc structure, the contact area between the sponge 6 and the surface of the wire is more uniform when they contact, improving the cleaning effect of the sponge 6 on the surface of the wire.
