Description

Technical Field

[0001] This utility model relates to the field of charging gun wire harness technology, and in particular to a multi-station crimping platform for charging gun wire harnesses. Background Technology

[0002] With the popularization of new energy vehicles, the construction of charging infrastructure has become crucial. As a vital interface for charging new energy vehicles, the performance and reliability of the charging gun directly affect charging efficiency and safety. Therefore, the manufacturing of charging gun harnesses requires efficient, precise, and reliable technologies, leading to the emergence of new crimping technologies and equipment. For example, ultrasonic metal welding technology, due to its advantages such as low resistance and high stability, is being increasingly widely used in the production of charging gun harnesses. Furthermore, the emergence of multi-station crimping platforms makes it possible to process multiple crimping points simultaneously, further improving production efficiency.

[0003] Most existing multi-station crimping platform technologies for charging gun harnesses suffer from excessive crimping force, leading to cracking at the crimping point between the terminal and the harness, which significantly reduces the crimping quality. Furthermore, the terminals are difficult to remove after crimping, limiting their practicality. Therefore, we propose a multi-station crimping platform for charging gun harnesses to address this problem. Utility Model Content

[0004] The purpose of this invention is to provide a multi-station crimping platform for charging gun harnesses to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A multi-station crimping platform for charging gun harnesses includes: a workbench; a second U-shaped frame fixedly mounted on the top of the workbench; a hydraulic cylinder fixedly mounted on the inner top of the second U-shaped frame; a movable plate fixedly connected to the output end of the hydraulic cylinder; multiple telescopic columns fixedly mounted on the bottom of the movable plate; crimping plates fixedly mounted at the bottom of each telescopic column; return springs fixedly connected to the top of each crimping plate; and the tops of each return spring fixedly mounted on the bottom of the movable plate, with each return spring sleeved on a corresponding telescopic column. On the outer side, a placement plate is fixedly installed on the inner side of the second U-shaped frame. The top of the placement plate has multiple placement slots, and a top plate is movably abutted in each of the multiple placement slots. A rotating rod is rotatably installed inside the second U-shaped frame. Multiple second worm gear segments are fixedly installed on the outer side of the rotating rod. Second worm wheels are meshed on the outer side of each of the multiple second worm gear segments. Threaded rods are fixedly installed inside each of the multiple second worm wheels. Threaded cylinders are threadedly connected to the outer side of each of the multiple threaded rods. The top ends of the multiple threaded cylinders are fixedly installed on the bottom of the corresponding top plate.

[0007] Preferably, a first U-shaped frame is fixedly installed on the top of the workbench, a support frame is fixedly installed on the outer side of the first U-shaped frame, a second motor is fixedly installed on the inner side of the support frame, a rotating shaft is fixedly connected to the output end of the second motor, two first worm gear segments are fixedly installed on the outer side of the rotating shaft, a first worm wheel is meshed on the outer side of each of the two first worm gear segments, a double-acting screw is fixedly installed inside each of the two first worm wheel segments, two T-shaped sliders are threadedly connected to the outer side of each of the two double-acting screws, a fixing plate is fixedly installed between each of the corresponding two T-shaped sliders, and multiple clamping plates are fixedly installed on the side of each of the two fixing plates that are close to each other.

[0008] Preferably, two support plates are fixedly installed on the top of the workbench, and two rotating shafts are rotatably installed between the two support plates. A motor is fixedly installed on the front side of one of the support plates, and the output end of the motor is fixedly connected to one end of the corresponding rotating shaft. Multiple conveying rollers are fixedly installed on the outer side of both rotating shafts.

[0009] Preferably, a No. 3 motor is fixedly installed on the front side of the No. 2 U-shaped frame, the output end of the No. 3 motor is fixedly connected to one end of the rotating rod, and multiple guide columns are fixedly installed on the top of the workbench. Each of the multiple guide columns has an L-shaped connecting plate fixedly installed on its top, and the tops of two corresponding L-shaped connecting plates are fixedly installed on the bottom of the corresponding top plate.

[0010] Preferably, the bottom ends of the plurality of threaded rods are rotatably mounted on the top inner side of the workbench, and two T-shaped moving blocks are fixedly mounted on the outer side of the moving plate. T-shaped moving grooves are opened on both sides of the inner side of the second U-shaped frame, and the outer sides of the two T-shaped moving blocks are slidably connected to the corresponding T-shaped moving grooves.

[0012] In this utility model, a multi-station crimping platform for charging gun harnesses is described. By activating a hydraulic cylinder, a moving plate and a T-shaped moving block move along a T-shaped moving groove, which in turn moves a telescopic column, a crimping plate, and a return spring along the T-shaped moving groove. This allows the crimping plate to crimp the terminals and harness together. Simultaneously, the cooperation of the telescopic column and the return spring during crimping prevents excessive crimping force from damaging the terminals, thus greatly improving the crimping quality. After crimping is complete, the hydraulic cylinder is activated in reverse to reset the telescopic column, crimping plate, and return spring. At this point, a third motor is activated, causing the rotating rod to rotate, which in turn rotates the second worm gear segment, causing the second worm wheel meshing with the second worm gear segment to rotate, which in turn rotates the threaded rod, causing the threaded cylinder threadedly connected to the threaded rod to move upwards, which in turn moves the top plate upwards. This allows the top plate to push out the crimped terminals inside the placement groove, facilitating terminal removal and broadening its practicality.

[0013] In this utility model, a multi-station crimping platform for charging gun wire harnesses is described. By starting a second motor, the rotating shaft starts to rotate, which in turn drives the first worm gear segment to rotate, which in turn drives the first worm wheel meshing with the first worm gear segment to rotate, which in turn drives the bidirectional screw to rotate, which in turn drives the T-shaped slider threadedly connected to the bidirectional screw to move along the T-shaped groove, which in turn drives the fixing plate and clamping plate to move along the T-shaped groove, further fixing the wire harness and preventing the wire harness from moving during crimping.

[0014] This utility model has a reasonable structural design. The cooperation between the telescopic column, the crimping plate and the return spring can prevent excessive crimping force from damaging the terminal, thereby greatly improving the crimping quality. At the same time, the cooperation between the No. 3 motor, the rotating rod, the No. 2 worm gear section, the No. 2 worm wheel, the threaded rod, the threaded cylinder and the top plate makes it easy to remove the terminal, making it more practical.

[0025] In this embodiment, the bottom ends of multiple threaded rods 33 are rotatably mounted on the top inner side of the workbench 1.

[0026] In this embodiment, during use, the wire harness is passed between the two corresponding conveyor rollers 5. Then, the first motor 3 is started, which drives the rotating shaft 4 and the conveyor rollers 5 to rotate, thereby moving the wire harness to the top of the placement groove 27. Then, the terminal is placed inside the placement groove 27. At this time, the second motor 8 is started, which drives the rotating shaft 9 to rotate, thereby driving the first worm gear segment 10 to rotate, which in turn drives the first worm wheel 11 meshing with the first worm gear segment 10 to rotate, which in turn drives the bidirectional screw 12 to rotate, thereby driving the T-shaped slider 13 threadedly connected to the bidirectional screw 12 to move along the T-shaped slide groove 14, thereby driving the fixing plate 15 and the clamping plate 16 to move along the T-shaped slide groove 14, further fixing the wire harness with the clamping plate 16 to prevent the wire harness from moving during crimping. Then, the hydraulic cylinder 19 is started, which drives the moving plate 20 and the T-shaped moving block 21 to move along the T-shaped moving groove 22. The movement of the telescopic column 23, crimping plate 24, and return spring 25 along the T-shaped moving groove 22 causes the crimping plate 24 to crimp the terminal and wire harness together. During crimping, the cooperation of the telescopic column 23 and return spring 25 prevents excessive crimping force from damaging the terminal, thus greatly improving the crimping quality. After crimping, the hydraulic cylinder 19 is activated in reverse to reset the telescopic column 23, crimping plate 24, and return spring 25. At this time, the third motor 29 is activated, causing the rotating rod 30 to rotate, which in turn causes the second worm gear section 31 to rotate, which in turn causes the second worm wheel 32, meshing with the second worm gear section 31, to rotate, which in turn causes the threaded rod 33 to rotate, causing the threaded cylinder 34, threadedly connected to the threaded rod 33, to move upwards, which in turn causes the top plate 28 to move upwards, thus pushing the crimped terminal out of the placement groove 27, making it easier to remove the terminal and broadening its practicality.
