Description

Technical Field

[0001] This utility model relates to the field of wire harness crimping technology, and more specifically, to a fully automatic crimping device for vehicle-mounted wire harnesses. Background Technology

[0002] The fully automatic crimping device for vehicle wiring harnesses is a machine used in wire processing. It crimps the metal terminals to the wire ends and then makes them conductive. The crimped terminals can be connected without soldering, making it convenient to use.

[0003] The fully automatic crimping device for vehicle wiring harnesses consists of multiple components, among which the wire harness cutting part is an indispensable part of the fully automatic crimping machine. However, in the existing technology, the cutting part is usually the entire cutting device exposed outside the machine body. As an easily damaged and exposed part, the cutting blade is greatly increased by the lack of protective devices during the operation of the machine, which may lead to accidents or cuts. Utility Model Content

[0004] The purpose of this invention is to provide a fully automatic crimping device for vehicle wiring harnesses to solve the problem of the lack of protection for the cutting device in the prior art.

[0005] To achieve the above objectives, a fully automatic crimping device for vehicle wiring harnesses is provided, comprising a base and a cutting mechanism disposed above the base. The center of the base is fixed to a cutting table by multiple screws. A first bracket is fixedly connected above the cutting table. Limiting rods are threaded into slots on both sides of the first bracket near the edge. A lower die is fixedly connected to the center of the first bracket. The lower die has multiple slots with different diameters. Each slot has a semi-circular protective opening from the center. The cutting mechanism includes a cutting blade. The protective opening is used to prevent the cutting blade from breaking and splashing when it is pressed down to cut the wire. The protective opening slot is in contact with the cutting blade during machine operation.

[0006] As a further improvement to this technical solution, the cutting mechanism includes an L-shaped plate located on the side of the base near the edge. The L-shaped plate is fixed to the bottom of the cylinder by multiple screws. The output end of the cylinder passes through the L-shaped plate and is fixed to the telescopic plate. A second bracket is fixedly connected below the telescopic plate. An upper die is slidably connected in a slot below the second bracket. A plurality of slots with different diameters are opened on one side of the upper die, and a cutting knife is held in the slot.

[0007] As a further improvement to this technical solution, the sliding rod is divided into upper and lower sections. The end of the limiting rod away from the first bracket is threadedly connected to the second bracket. When the cylinder is running, it drives the telescopic plate and the second bracket to move axially. The limiting rod is used to prevent the cutting knife from dislodging from the protective opening during axial movement.

[0008] As a further improvement to this technical solution, connecting plates are symmetrically fixedly connected to both sides of the telescopic plate. The outer side of the connecting plate is fixed to the slider by multiple screws. A sliding rod is slidably connected in the slot opened at the center of the upper part of the slider. The top of the sliding rod is fixed to the L-shaped plate.

[0009] As a further improvement to this technical solution, the slider slides axially along the sliding rod to prevent the telescopic plate driven by the cylinder from rotating and deviating. A wire threading plate is fixedly connected to the side of the base away from the L-shaped plate. The wire threading plate has multiple insertion holes of different diameters on one side, and each insertion hole corresponds to a wire cutter.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] This fully automatic vehicle wiring harness crimping device is equipped with a protective port that matches the cutting blade to prevent operators from coming into contact with the blade during the cutting process, avoiding accidental cuts or scratches. In addition, the sliding rod connecting the brackets on both sides ensures that the entire cutting mechanism does not shift, reducing friction between the blade and the wiring harness, extending the blade's service life, preventing blade breakage and splashing, reducing the risk of accidents, and enabling the blade to maintain the correct cutting angle and position during the cutting process, thus improving cutting accuracy.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example: Please refer to Figures 1-4 As shown, the purpose of this embodiment is to provide a fully automatic crimping device for vehicle wiring harnesses, including a base 100 and a cutting mechanism 200 disposed above the base 100. The center of the base 100 is fixed to a cutting table 101 by multiple screws. A first bracket 102 is fixedly connected above the cutting table 101. Limiting rods 105 are threaded into slots near the edges on both sides of the first bracket 102. A lower die 103 is fixedly connected to the center of the first bracket 102. The lower die 103 has multiple slots of different diameters, and each slot has a semi-circular protective opening 104 extending from the center. The cutting mechanism 200 includes a cutting blade 209. The protective opening 104 is used to prevent the wire cutter 209 from breaking and splashing when it is pressed down to cut the wire. The groove of the protective opening 104 is in contact with the wire cutter 209 when the machine is running. The protective opening 104 completely encloses the pressed wire cutter 209, so that the wire cutter 209 can create a closed space during operation. Even if the wire cutter 209 is worn out and breaks, the broken wire cutter 209 can be kept in the protective opening 104 to prevent the blade from splashing and injuring people. At the same time, the closed space can also prevent the operator from coming into contact with the wire cutter 209 during operation and avoid accidental cuts or scratches due to operator fatigue.

[0021] Furthermore, to achieve higher cutting precision in this fully automatic crimping device for vehicle wiring harnesses, the cutting mechanism 200 includes an L-shaped plate 201. The L-shaped plate 201 is located above the base 100 near the edge. Multiple screws secure the L-shaped plate 201 to the bottom of the cylinder 202. The output end of the cylinder 202 passes through the L-shaped plate 201 and is fixed to a telescopic plate 203. A second bracket 207 is fixedly connected below the telescopic plate 203. An upper die 208 is slidably connected within a slot below the second bracket 207. Multiple slots of different diameters are provided on one side of the upper die 208, and a cutting blade 209 is held within each slot. The limiting rod 105 is divided into upper and lower sections. The end of the limiting rod 105 away from the first bracket 102 is threadedly connected to the second bracket 207. When the cylinder 202 is running, it drives the telescopic plate 203 and the second bracket 207 to move axially. The limiting rod 105 is used to prevent the cutting blade 209 from disengaging from the protective opening 104 during axial movement. The two parts of the limiting rod 105 slide axially between the first bracket 102 and the second bracket 207, so that the cutting blade 209 completely matches the protective opening 104 during the downward pressing process. This enables the cutting blade 209 to maintain the correct cutting angle and position during the cutting process, thereby improving the cutting accuracy.

[0022] Furthermore, to extend the lifespan of the fully automatic crimping device for vehicle wiring harnesses, connecting plates 204 are symmetrically fixed to both sides of the telescopic plate 203. The outer sides of the connecting plates 204 are fixed to the slider 205 by multiple screws. A sliding rod 206 is slidably connected within a slot at the center of the upper part of the slider 205. The top of the sliding rod 206 is fixed to the L-shaped plate 201. The slider 205 slides axially along the sliding rod 206 to prevent the telescopic plate 203 driven by the cylinder 202 from rotating or shifting. The base 100 is located away from the L-shaped plate 201. A wire guide plate 106 is fixedly connected to one side. Multiple insertion holes 107 of different diameters are opened on one side of the wire guide plate 106. The insertion holes 107 correspond one-to-one with the wire cutter 209. The top of the sliding rod 206 is fixed to the L-shaped plate 201, so that the slider 205 moves along the axis of the sliding rod 206. When the cylinder 202 drives the telescopic plate 203 to move, the slider 205 and the sliding rod 206 distributed on both sides will prevent the wire cutter 209 from deviating, reduce the friction between the wire cutter 209 and the wire harness, and extend the service life of the wire cutter 209.

[0023] The working principle of this device is as follows: After the operator starts the fully automatic crimping device for vehicle wiring harnesses, the wiring harness is fed into the insertion hole 107 of a suitable diameter, extending to the corresponding protective port 104 and the cutting blade 209. After starting the cylinder 202, the output end of the cylinder 202 guides the fixedly connected telescopic plate 203 to press down. The connecting plates 204 at both ends of the telescopic plate 203 are connected to the slider 205, which slides axially outside the sliding rod 206. The second bracket 207 at the bottom of the telescopic plate 203 drives the upper die 208 and the cutting blade 209 on one side of the upper die 208 to press down for cutting. During the cutting operation, the cutting blade 209 is completely protected by the protective port 104 provided by the lower die 103, so that the cutting blade 209 can create a closed space during operation. Even if the cutting blade 209 is worn out and breaks, the broken cutting blade 209 can be kept within the protective port 104 to prevent the blade from flying and injuring people. At the same time, The enclosed space also prevents workers from coming into contact with the cutting blade 209 during operation, avoiding accidental cuts or scratches due to fatigue. The top of the sliding rod 206 is fixed to the L-shaped plate 201, allowing the slider 205 to move axially along the sliding rod 206. When the cylinder 202 drives the telescopic plate 203, the sliders 205 and sliding rod 206 on both sides prevent the cutting blade 209 from deviating, reducing friction between the cutting blade 209 and the wire harness and extending the service life of the cutting blade 209. The two ends of the limiting rod 105 are threaded to the first bracket 102 and the second bracket 207 respectively, preventing the cutting blade 209 from disengaging from the protective opening 104 during axial movement. The two parts of the limiting rod 105 slide axially on the first bracket 102 and the second bracket 207, ensuring that the cutting blade 209 completely matches the protective opening 104 during downward pressing. This allows the cutting blade 209 to maintain the correct cutting angle and position during cutting, improving cutting accuracy.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
