Description

Technical Field

[0001] This utility model relates to the technical field of automotive crimp terminal lubrication devices, and in particular to a lifting oil box type crimp terminal lubrication device. Background Technology

[0002] Crimping terminals are critical components in electrical connections, and their reliability directly affects electrical performance, mechanical strength, and long-term stability. Currently, crimping terminals used in automotive wiring harness production are mostly chain-type terminals wound on terminal reels for continuous processing. When crimping terminals with wires, lubricating oil needs to be applied to reduce the insertion resistance of the wires during crimping, making it easier for the terminal and wire to fit together, and reducing heat accumulation caused by friction, thus preventing high temperatures from affecting crimping quality. Existing chain-type terminals, when used with semi-automatic and automated crimping equipment, apply crimping oil from the oil box to the crimping terminals by rotating a brush holder connected to the oil box and rotating brushes radially arranged on the brush holder. However, this structure makes it easy for the crimping oil at the ends of the brushes to be thrown out by centrifugal force when rotating, resulting in poor crimping oil application quality in rapid continuous production. Utility Model Content

[0003] This utility model provides a lifting oil box type crimping terminal lubrication device to solve the above-mentioned technical problems.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows: A lifting oil box type crimping terminal lubrication device includes: an oil box, a wheel axle disposed in an oil groove in the oil box, and an oil suction wheel for absorbing crimping oil from the oil groove. The oil suction wheel is sleeved on the wheel axle and rotatably connected to the oil box through the wheel axle. The oil suction wheel adopts a multi-hole structure.

[0005] Preferably, the oil suction wheel is a sponge wheel or a leather wheel.

[0006] Preferably, the oil suction wheel is coaxially fixed on the axle, and two mounting slots are opened on the opposite side walls of the oil tank of the oil box. A bearing seat is installed in the mounting slot, and the two ends of the axle are rotatably connected to the bearing seat.

[0007] Preferably, the bearing seat is provided with a mounting hole, and the end of the axle can be rotatably inserted into the mounting hole.

[0008] Preferably, the mounting groove extends to the upper surface of the oil box, and the upper end of the shaft seat protrudes from the mounting groove; a pressure strip is detachably mounted on the oil box, and the pressure strip presses against the upper end of the shaft seat.

[0009] Preferably, two spacers are fitted on the axle, with the two spacers located at both ends of the oil suction wheel. One end of the spacer abuts against the shaft seat, and the other end abuts against the end face of the oil suction wheel.

[0010] Preferably, the oil box is mounted on the base via a lifting adjustment component, which is used to adjust the height of the oil box.

[0011] Preferably, the lifting adjustment assembly includes a lifting column fixed on the base and at least two locking screws. The lifting column has a vertical elongated hole, and the two locking screws pass through the elongated hole and are screwed into two second threaded holes on the oil box, respectively, and the two locking screws are arranged vertically.

[0012] Preferably, a magnet is installed on the base for adsorption and fixation on the crimping equipment.

[0013] Preferably, the bottom surface of the base has a countersunk hole, and the magnet is a cylinder and is embedded in the countersunk hole.

[0014] Beneficial effects: The lifting oil box type crimping terminal lubrication device disclosed in this application uses a porous oil suction wheel to rotate. The oil suction wheel rotates under the forward drive of the chain terminal, so that the part of the oil suction wheel immersed in the terminal crimping oil rotates to the top, and the terminal crimping oil adsorbed on the oil suction wheel is applied to the crimping terminal. Because the diameter and porous structure of the oil suction wheel can effectively absorb grease, it can prevent the terminal crimping oil from being thrown out during rotation.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] A lifting oil box type crimp terminal lubrication device, combined with Figures 1-9 As shown, the device includes: an oil box 1, a wheel axle 2 disposed within an oil groove 11 in the oil box 1, and an oil suction wheel 3 for absorbing terminal crimping oil from the oil groove 11. The oil suction wheel 3 is sleeved on the wheel axle 2 and rotatably connected to the oil box 1 via the wheel axle 2. The oil suction wheel 3 has a porous structure. This application utilizes the porous structure of the oil suction wheel 3 for rotation. Driven by the forward movement of the chain-type terminals, the portion of the oil suction wheel 3 immersed in the terminal crimping oil rotates to the top, adsorbing the terminal crimping oil onto the crimping terminals. Due to the diameter and porous structure of the oil suction wheel 3, which effectively absorbs grease, it prevents the terminal crimping oil from being thrown out during rotation. Therefore, this application can reliably and smoothly apply oil to the crimping terminals as the chain-type terminals continuously crimp. The lubrication of the crimping terminals reduces friction between the crimping terminals and the wires or mold during the crimping process, prevents scratches on the metal surface and prevents increased resistance after oxidation, reduces poor contact caused by vibration, and ensures stable current transmission in the product. This invention ensures the stability of key technical parameters such as terminal height, terminal width, and core wire wrapping during the crimping process of each crimped terminal, reducing incomplete crimping saturation and guaranteeing crimping quality. Furthermore, this application can be used on crimping equipment such as fully automatic shell insertion machines, fully automatic double-end crimping machines, and semi-automatic hand crimping machines, reducing worker fatigue and improving work efficiency.

[0020] Preferably, the oil-absorbing wheel 3 is made of sponge or leather, whose porous structure can effectively absorb grease, and its lightweight nature also facilitates rotation as the chain terminal moves forward. At the same time, these two types of wheels are inexpensive and easy to replace after wear.

[0021] Preferably, the oil suction wheel 3 is coaxially fixed on the axle 2, and two mounting slots 12 are formed on the opposite sidewalls of the oil groove 11 of the oil box 1. A bearing seat 4 is installed in each mounting slot 12, and both ends of the axle 2 are rotatably connected to the bearing seat 4. This application enables the axle 2 to rotate smoothly by providing the bearing seat 4, and allows the bearing seat 4 to be made of a more wear-resistant material than the oil box 1, thereby reducing the frequency of bearing seat 4 replacement.

[0022] Preferably, the bearing seat 4 is provided with a mounting hole 41, and the end of the wheel axle 2 is rotatably inserted into the mounting hole 41 to ensure that the wheel axle 2 rotates relative to the bearing seat 4, and has the advantages of simple processing and low cost.

[0023] Preferably, the mounting groove 12 extends to the upper surface of the oil box 1, and the upper end of the shaft seat 4 protrudes through the mounting groove 12; a pressure strip 5 is detachably mounted on the oil box 1, and the pressure strip 5 presses against the upper end of the shaft seat 4. In this application, the shaft seat 4 is pressed and fixed in the mounting groove 12 by the pressure strip 5, and the shaft seat 4 can be removed by removing the pressure strip 5, thereby facilitating the replacement of the oil suction wheel 3. At the same time, the cooperation of the pressure strip 5, the shaft seat 4, and the mounting groove 12 can ensure the installation position of the wheel axle 2, and ensure that the outer peripheral surface of the oil suction wheel 3 is at the same level as the crimp terminal, thereby ensuring reliable contact between the outer peripheral surface of the oil suction wheel 3 and the crimp terminal, and avoiding the situation where some parts of the crimp terminal are not oiled or have insufficient oil.

[0024] Specifically, the mounting groove 12 is rectangular, and the bearing seat 4 has a rectangular structure that matches the dimensions of the mounting groove 12. After the bearing seat 4 is inserted into the mounting groove 12, it prevents twisting. The upper end of the bearing seat 4 protrudes above the upper surface of the oil box 1. Two first threaded holes are machined on the upper surface of the oil box 1, located on both sides of the mounting groove 12. Two through holes are machined on the pressure strip 5. Two first fixing screws pass through the through holes and are screwed into the first threaded holes to fix the pressure strip 5, thereby pressing the pressure strip 5 against the upper end face of the bearing seat 4, thus pressing and fixing the bearing seat 4 within the mounting groove 12. When disassembly is required, the pressure strip 5 and bearing seat 4 can be removed by removing the first fixing screws.

[0025] Preferably, two spacers 6 are fitted on the axle 2, located at both ends of the oil suction wheel 3. One end of the spacer 6 abuts against the shaft seat 4, and the other end abuts against the end face of the oil suction wheel 3. The two spacers 6 limit the position of the oil suction wheel 3 on the axle 2, ensuring that the oil suction wheel 3 is always aligned with the pressure terminal.

[0026] Preferably, the oil box 1 is mounted on the base 7 via a lifting adjustment component, which is used to adjust the height of the oil box 1. After the crimping terminal is placed on the oil suction wheel 3, the height of the oil box 1 is adjusted to be at the same level as the crimping mold. No secondary operation by the operator is required. After the crimping equipment is running, it drives the crimping terminal forward, and the crimping terminal drives the oil suction wheel 3 to rotate. The crimping terminal on the oil suction wheel 3 is evenly coated with crimping oil, thereby protecting the metal surface of the crimping terminal, extending the life of the crimping mold, preventing terminal oxidation and corrosion, and improving the conductivity stability of the product.

[0027] The lifting adjustment assembly includes a lifting column 81 fixed to the base 7 and at least two locking screws 82. The lifting column 81 has a vertical elongated hole 811. The two locking screws 82 pass through the elongated hole 811 and are screwed into two second threaded holes on the oil box 1, respectively, with the two locking screws 82 arranged vertically. By loosening the two locking screws 82, the oil box 1 can be moved vertically along the elongated hole 811 for height adjustment. In this embodiment, the locking screws 82 are also equipped with washers. The lifting column 81 is fixedly connected to the base 7 by second fixing screws.

[0028] Preferably, a magnet is installed on the base 7 for adsorption and fixation on the crimping equipment, which makes it easy to pick up and put down the base 7 and adjust its position, which is beneficial for continuous crimping of terminals, improving crimping efficiency and ensuring stable quality.

[0029] The base 7 has a countersunk hole 71 on its bottom surface, and the magnet, being a cylinder, is embedded in the countersunk hole 71. The magnet is fixed to the large-diameter section of the countersunk hole 71 by interference fit or adhesive, and the end face of the magnet is recessed into the countersunk hole 71, allowing the base 7 to completely conform to the surface to be attracted. When the magnet's magnetism decreases, it can be pushed out from the small-diameter section of the countersunk hole 71 for replacement.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
