Description

Technical Field

[0001] This utility model relates to the field of automotive charging gun manufacturing technology, specifically a pneumatic wire cutting machine for automotive charging gun manufacturing. Background Technology

[0002] With the rapid development of the global new energy vehicle industry, the demand for electric vehicles (EVs) and charging infrastructure continues to surge. As a core component connecting electric vehicles to charging piles, the market demand for car charging guns is growing exponentially, placing higher demands on the precision, efficiency, and reliability of their manufacturing processes. One of the core components of a charging gun is its internal cable (usually a multi-strand copper core wire with an insulating outer layer), and its cutting is a critical step in the production process—the cable must be precisely cut to a specified length.

[0003] Upon investigation, it was found that existing equipment relies entirely on the operator's experience and strength control through handheld fixing. Cables are prone to displacement and slippage due to hand tremors, uneven force, or the reaction force when the cutter is pressed down, resulting in problems such as misaligned cuts, tilted cuts, or excessive burrs. These defects directly affect the contact area and conductivity of the crimped terminals, and may even cause safety hazards such as short circuits or signal transmission interruptions. In response to the above situation, technological innovations will be carried out on the basis of existing devices. Utility Model Content

[0017] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0018] Please see Figure 1 - Figure 5This utility model provides a technical solution: a pneumatic wire cutter for producing automotive charging guns, comprising a pneumatic wire cutter 1. The pneumatic wire cutter 1 has a lower shearing blade 19 and an upper shearing blade 20 internally. A cylinder is also installed inside the pneumatic wire cutter 1. The cylinder pushes the upper shearing blade 20 downwards to cut the cable at the top of the lower shearing blade 19. The pneumatic wire cutter 1 is an existing structure and will not be described in detail here. A fixing block 2 is fixedly connected to the surface of the pneumatic wire cutter 1. A transmission groove 8 is formed inside the fixing block 2. The internal rotating connection is a disc 9, the surface of which is provided with teeth. The internal rotating connection of the transmission groove 8 is a gear 10, the surface of which is connected to the surface of the disc 9 by tooth meshing. The surface of the fixed block 2 is fixedly connected to a motor 3, the output end of which is fixedly connected to one side of the gear 10. The surface of the disc 9 has two arc-shaped grooves 11, and the interior of each arc-shaped groove 11 is slidably connected to a transmission block 12. The side of the transmission block 12 away from the arc-shaped groove 11 is fixedly connected to a transmission rod 6. The surface of the fixed block 2 is open A sliding groove 5 is provided, and the width of the arc-shaped groove 11 is much larger than the width of the sliding groove 5. The interior of the sliding groove 5 is slidably connected to the surface of the transmission rod 6. A connecting rod 7 is fixedly connected to the side of the transmission rod 6 away from the transmission block 12. An arc-shaped clamping plate 4 is fixedly connected to one side of the connecting rod 7. A rubber pad is provided on one side of the arc-shaped clamping plate 4. The arc-shaped clamping plate 4 can clamp the cable, and at the same time, the rubber pad on the surface prevents the cable from being damaged during clamping. By starting the motor 3, the gear 10 is driven to rotate. At the same time, because the surface of the gear 10 is in contact with the disc 9, the gear 10 rotates. The surfaces are connected by toothed meshing, which causes the disc 9 to drive the internal transmission block 12 to slide inside the arc-shaped groove 11, and drive the transmission rod 6 on one side of the transmission block 12 to slide inside the slide groove 5. At the same time, the sliding of the transmission block 12 is limited, so that the two arc-shaped clamping plates 4 can move relative to each other to clamp the cable. Meanwhile, the rubber pads on the surface prevent the cable from being damaged during clamping, ensuring that the cable is cut to a consistent length, with a flat cross-section and no burrs. This greatly improves the product quality consistency and pass rate of the charging gun production.

[0019] The pneumatic wire cutter 1 has an internal limit plate 14 that limits the cable to be cut. A cylindrical block 15 is fixedly connected to one side of the limit plate 14. A threaded rod 16 is rotatably connected inside the pneumatic wire cutter 1, and the surface of the threaded rod 16 is threadedly connected to the inside of the cylindrical block 15. A handle 17 is rotatably connected to the surface of the pneumatic wire cutter 1, and one end of the handle 17 is fixedly connected to one end of the threaded rod 16. A guide rail 13 is provided inside the pneumatic wire cutter 1, and the guide rail 13 has a size scale that can be adjusted to the required length. The surface of the guide rail 13 is slidably connected to the inside of the limit plate 14, and the guide rail 13 can limit the limit plate 14, so that the limit plate 14 is within the guide rail 13. The pneumatic wire cutter 1 slides on the surface. By rotating the handle 17, the threaded rod 16 is driven to rotate. At the same time, the threaded rod 16 is connected to the cylindrical block 15 by threads, which causes the cylindrical block 15 to drive the limiting plate 14 to slide on the surface of the guide rail 13. The limiting plate 14 slides to a certain position to cut the cable. The bottom of the pneumatic wire cutter 1 is provided with a collection groove 21 and a collection box 18. After the cable is cut, the cut cable can enter the inside of the collection box 18 through the collection groove 21 to collect the cut cable. The cut cable can be collected without the need for manual bending over to pick up or sort the cable, reducing operator intervention and preventing the cable from scattering around the equipment, thus reducing the accumulation of debris on the workshop floor.

[0020] Working Principle: This type of pneumatic wire cutter for automotive charging gun production firstly, when cable cutting is required, the motor 3 is started, driving the gear 10 to rotate. Simultaneously, because the surface of the gear 10 is connected to the surface of the disc 9 through tooth meshing, the disc 9 drives the internal transmission block 12 to slide within the arc-shaped groove 11. This causes the transmission rod 6 on one side of the transmission block 12 to slide within the sliding groove 5. The sliding of the transmission block 12 is limited, allowing the two arc-shaped clamping plates 4 to move relative to each other, clamping the cable. Rubber pads on the surface prevent damage to the cable during clamping, ensuring that all cut cables are of consistent length, with smooth cut surfaces and no burrs. This greatly improves the consistency and pass rate of charging gun production, reduces operation time, lowers labor intensity, and increases production efficiency.

[0021] When the cable needs to be cut to a certain length, the threaded rod 16 is rotated by turning the handle 17. At the same time, the threaded rod 16 is connected to the cylindrical block 15 by threads, which causes the cylindrical block 15 to move the limiting plate 14 on the surface of the guide rail 13. The limiting plate 14 can be precisely slid to the required position by the size scale on the surface of the guide rail 13, so that the cable is flush with the limiting plate 14. The cable is then clamped by the two arc-shaped clamping plates 4, and the pneumatic wire cutter 1 is started. The lower cutting blade 19 and the upper cutting blade 20 work together to cut the cable to the required length, which greatly reduces downtime during product changeovers and improves production efficiency. The cut cable enters the collection box 18 through the collection trough 21 for collection. There is no need for manual bending over to pick up or sort the cable, which reduces operator intervention, prevents the cable from scattering around the equipment, reduces the accumulation of debris on the workshop floor, reduces the risk of safety accidents, and improves the overall aesthetics and space utilization of the equipment.

[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
