Description

Technical Field

[0001] This utility model relates to the field of wire harness processing technology, specifically a crimping machine for processing automotive lighting wire harnesses. Background Technology

[0002] Crimping of terminals has gradually replaced the previous welding process. Crimping of terminals is an important step in the wire assembly process. By applying external force, the wire core is reliably joined to the terminal. It is simple and easy to operate and has been widely used in the electrical, electronic, and automotive industries.

[0003] According to a public notice (No.: CN219535132U) regarding a crimping machine for wire harness terminals, the anti-pressure mechanism in the above application requires that the wire harness and terminals be placed into the mold through the through slots on the lifting frame and the rotating plate during the crimping production operation. The anti-pressure mechanism can protect the worker's hands from being inserted into the mold, thereby reducing the occurrence of machine-related safety accidents during the crimping production operation to a certain extent.

[0004] However, in actual use, the terminal diameter of the wire harness is often larger than the diameter of the wire harness. When passing wire harnesses of different diameters through the through slot, it is necessary to repeatedly rotate the turntable to adjust the distance of the moving block, and then repeatedly rotate the knob to control the fixing and sliding of the moving block. This process wastes a lot of time and heat, reducing the efficiency of the crimping machine. In view of this, we propose a crimping machine for processing automotive lighting wire harnesses. Summary of the Invention

[0005] The purpose of this invention is to provide a crimping machine for processing automotive lighting wiring harnesses, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a crimping machine for processing automotive lighting wiring harnesses, comprising a housing, a control board fixedly connected to the outer wall of the housing, a base fixedly connected to the lower outer wall of the housing, a crimping rod fixedly connected to the outer wall of the housing, a crimping assembly provided at the output end of the crimping rod, a stop fixedly connected to the inner wall of the housing, a baffle slidably connected to the inner wall of the housing, and a positioning assembly provided inside the baffle, the positioning assembly comprising: A toothed ring is rotatably connected to the inner wall of a baffle. A through groove is provided on the outer wall of the toothed ring, and a sliding rod is slidably connected to the inner wall of the groove. A slider is fixedly connected to the outer wall of the end of a slide rod. A gear is fixedly connected to the outer wall of the gear ring, and a rotating handle is fixedly connected to the shaft of the gear. A limiting groove is formed on one end of the baffle near the pressing assembly. The end of the slide rod away from the slider passes through the toothed ring and is slidably connected to the inner wall of the limiting groove. A limiting rod is fixedly connected to the inner wall of the limiting groove. The limiting rod passes through the slide rod. A return spring is sleeved on the outer wall of the limiting rod.

[0007] Preferably, the base has an internal mounting assembly, which includes a slot on the outer wall of the base. A fixing block is slidably connected to the inner wall of the slot. A locking spring is connected to the outer wall of the fixing block. A push rod is fixedly connected to the upper outer wall of the fixing block. An insert block is fixedly connected to the lower outer wall of the baffle. A locking block is fixedly connected to the outer wall of the insert block. When the baffle is damaged, the push rod can be pushed to move the fixing block, causing the fixing block to retract and move away from the insert block.

[0008] Preferably, the end of the locking block near the pressing assembly is provided with an arc surface, and the end of the fixing block away from the pressing assembly is provided with an arc surface. The arc surface of the fixing block contacts the arc surface of the locking block. When the arc surface of the fixing block contacts the arc surface of the locking block, the locking block can more easily push the fixing block to move, causing the fixing block to retract, thereby enabling the insert block to move. When the locking block leaves the fixing block, the plane of the locking block contacts the plane of the fixing block, making it difficult for the fixing block to move.

[0009] Preferably, the outer wall of the baffle is provided with a through groove, the opening size of the toothed ring is larger than the size of the through groove, the slider passes through the inner wall of the through groove and is slidably connected to the inner wall of the through groove, after the handle is rotated, the gear drives the toothed ring to rotate, causing the slide rod to move in the slide groove, so that the slide rod can drive the slider to move on the inner wall of the through groove.

[0010] Preferably, the number of sliders is set to eight groups, and the eight groups of sliders are distributed in a circumferential array on the inner wall of the through groove. The end of the slider away from the slide rod has a concave surface. When the slider moves towards the center of the through groove, the space enclosed by the slider decreases, and when the slider moves away from the center of the through groove, the space enclosed by the slider increases.

[0011] Preferably, the limiting groove is rectangular, and the end of the slide rod that contacts the inner wall of the limiting groove is rectangular. The outer wall of the slide rod fits against the inner wall of the limiting groove, so that when the slide rod moves along the groove, it can be limited by the limiting groove and cannot rotate, thereby allowing the slider to move stably on the inner wall of the through groove.

[0012] Preferably, one end of the return spring is fixedly connected to the inner wall of the limiting groove, the other end of the return spring is fixedly connected to the outer wall of the slide rod, and the end of the locking spring away from the fixing block is fixedly connected to the inner wall of the slot. When the handle is rotated to make the slider slide and open, the wire harness can be inserted. When the terminal of the wire harness moves to the fixing seat, the handle can be released, the return spring makes the slider return to its original position, so that the slider clamps the wire harness and keeps the wire harness in the center of the through groove.

[0013] Compared with the prior art, this utility model provides a crimping machine for processing automotive lighting wiring harnesses, which has the following beneficial effects: 1. This crimping machine for processing vehicle headlight wiring harnesses uses a rotating handle to drive a gear ring to rotate. At this time, the sliding rod moves within the sliding groove and the limiting groove, causing the slider to open. The wiring harness is then inserted. When the handle is released, the return spring causes the slider to return to its original position and clamp the wiring harness, keeping it centered in the through groove. This allows wiring harnesses of different diameters to be fixed without frequent unlocking, resulting in higher efficiency for the crimping machine.

[0014] 2. The crimping machine for processing vehicle lighting wiring harnesses can push a push rod to retract the fixing block away from the insert block when the baffle is damaged, allowing the baffle to be removed from the base. During installation, the insert block is pushed into the slot, at which point the locking block pushes the fixing block to retract. When the locking block leaves the fixing block, it pops out through a locking spring, making the plane of the locking block contact the plane of the fixing block, making it difficult for the fixing block to move and allowing the baffle to be fixed, making the installation and removal of the baffle more convenient and quick.

[0017] like Figures 1-5As shown, this utility model provides a technical solution: a crimping machine for processing vehicle lighting wiring harnesses, including a housing 1, a control plate 2 fixedly connected to the outer wall of the housing 1, a base 3 fixedly connected to the lower outer wall of the housing 1, a crimping rod 4 fixedly connected to the outer wall of the housing 1, a crimping assembly 5 provided at the output end of the crimping rod 4, a stop block 6 fixedly connected to the inner wall of the housing 1, a baffle 7 slidably connected to the inner wall of the housing 1, and a positioning assembly 8 provided inside the baffle 7. The positioning assembly 8 includes a toothed ring 81, a sliding groove 82, a sliding rod 83, a slider 84, a gear 85, a rotating handle 86, a limiting groove 87, a limiting rod 88, and a return spring 89.

[0018] In one embodiment of the present invention, the toothed ring 81 is rotatably connected to the inner wall of the baffle 7, and the outer wall of the toothed ring 81 is provided with a through groove 82, and the inner wall of the groove 82 is slidably connected to a slide rod 83.

[0019] In one embodiment of this utility model, a limiting groove 87 is formed on one end of the baffle 7 near the pressing assembly 5. The end of the slide rod 83 away from the slider 84 passes through the toothed ring 81 and is slidably connected to the inner wall of the limiting groove 87. A limiting rod 88 is fixedly connected to the inner wall of the limiting groove 87. The limiting rod 88 passes through the slide rod 83. A return spring 89 is sleeved on the outer wall of the limiting rod 88.

[0020] In one embodiment of the present invention, the toothed ring 81 is rotatably connected to the inner wall of the baffle 7, and the outer wall of the toothed ring 81 is provided with a through groove 82, and the inner wall of the groove 82 is slidably connected to a slide rod 83.

[0021] In one embodiment of this utility model, the crimping assembly 5 consists of a crimping block and a fixing seat. The crimping block is fixedly connected to the output end of the crimping rod 4, and the fixing seat is fixedly connected to the outer wall of the base 3.

[0022] In addition, the base 3 is equipped with an installation component 9, which includes a slot 91. The slot 91 is opened on the outer wall of the base 3. A fixing block 92 is slidably connected to the inner wall of the slot 91. A locking spring 93 is connected to the outer wall of the fixing block 92. A push rod 94 is fixedly connected to the upper outer wall of the fixing block 92. An insert block 95 is fixedly connected to the lower outer wall of the baffle 7. A locking block 96 is fixedly connected to the outer wall of the insert block 95. When the baffle 7 is damaged, the push rod 94 can be pushed, causing the push rod 94 to push the fixing block 92 to move, causing the fixing block 92 to retract and separate from the insert block 95, thereby allowing the baffle 7 to be removed from the base 3 for easy replacement.

[0023] In this embodiment of the present invention, the end of the locking block 96 near the pressing component 5 is provided with an arc surface, and the end of the fixing block 92 away from the pressing component 5 is provided with an arc surface. The arc surface of the fixing block 92 contacts the arc surface of the locking block 96. When the arc surface of the fixing block 92 contacts the arc surface of the locking block 96, the locking block 96 can more easily push the fixing block 92 to move, causing the fixing block 92 to retract, thereby allowing the insert block 95 to move. When the locking block 96 leaves the fixing block 92, the plane of the locking block 96 contacts the plane of the fixing block 92, making it difficult for the fixing block 92 to move, thereby allowing the locking block 96 to be fixed in the slot 91 by the fixing block 92, and allowing the baffle 7 to be fixed.

[0024] In an embodiment of this utility model, the outer wall of the baffle 7 is provided with a through groove. The opening size of the toothed ring 81 is larger than the size of the through groove. The slider 84 passes through the inner wall of the through groove and is slidably connected to the inner wall of the through groove. After rotating the handle 86, the gear 85 drives the toothed ring 81 to rotate, causing the slide rod 83 to move in the slide groove 82. This allows the slide rod 83 to drive the slider 84 to move on the inner wall of the through groove, enabling the slider 84 to limit the movement of wire harnesses of different diameters.

[0025] In this embodiment of the invention, eight sets of sliders 84 are arranged in a circular array on the inner wall of the through groove. The end of the slider 84 away from the slide bar 83 has a concave surface. When the slider 84 moves toward the center of the through groove, the space enclosed by the slider 84 decreases. When the slider 84 moves away from the center of the through groove, the space enclosed by the slider 84 increases. This allows the slider 84 to limit the movement of wire harnesses of different diameters.

[0026] In this embodiment of the present invention, the limiting groove 87 is set as a rectangle, and the end of the slide rod 83 that contacts the inner wall of the limiting groove 87 is set as a rectangle. The outer wall of the slide rod 83 fits against the inner wall of the limiting groove 87, so that when the slide rod 83 moves along the slide groove 82, it can be limited by the limiting groove 87 and cannot rotate, so that the slider 84 can move stably on the inner wall of the through groove, and thus the slider 84 can better fix wire harnesses of different diameters.

[0027] In this embodiment of the invention, one end of the return spring 89 is fixedly connected to the inner wall of the limiting groove 87, and the other end of the return spring 89 is fixedly connected to the outer wall of the slide rod 83. The end of the locking spring 93 away from the fixing block 92 is fixedly connected to the inner wall of the slot 91. When the rotating handle 86 is rotated to make the slider 84 slide and open, the wire harness can be inserted. When the terminal of the wire harness moves to the fixing seat, the rotating handle 86 can be released, and the return spring 89 makes the slider 84 return to its original position, thereby making the slider 84 clamp the wire harness and keep the wire harness in the center of the through groove. This allows wire harnesses of different diameters to be fixed without frequent unlocking, and the crimping machine is more efficient.

[0028] In this invention, during use, rotating the handle 86 causes the gear 85 to drive the gear ring 81 to rotate. At this time, the slide rod 83 moves within the slide groove 82 and the limiting groove 87, causing the slider 84 to move and open. The wire harness is then inserted. After the wire harness terminal moves onto the fixing seat of the crimping assembly 5, the handle 86 is released, and the return spring 89 resets the slider 84, causing it to retract and clamp the wire harness, keeping it centered in the through groove. This ensures that the terminal is evenly crimped by the pressure block of the crimping assembly 5, preventing the terminal from loosening when only one end is in contact with the pressure block and the terminal is not centered in the through groove. Furthermore, wire harnesses of different diameters do not require frequent unlocking to secure them, resulting in higher efficiency and reduced downtime. When plate 7 is damaged, push rod 94 can be pushed to move fixing block 92, causing fixing block 92 to retract and move away from insert block 95, thereby allowing baffle 7 to leave base 3 and be removed. During installation, push insert block 95 into slot 91. At this time, locking block 96 pushes fixing block 92 to move, causing fixing block 92 to retract, thereby allowing insert block 95 to move. When locking block 96 leaves fixing block 92, locking block 96 pops out through locking spring 93, so that the plane of locking block 96 contacts the plane of fixing block 92, making fixing block 92 difficult to move, thereby allowing locking block 96 to be fixed in slot 91 by fixing block 92, so that baffle 7 can be fixed, making the installation and removal of baffle 7 more convenient and quick.

[0029] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
