[0002] The wire harness production fixture consists of a wooden board, a frame, wire support jigs, and a paper fixture drawing. During assembly, the drawing needs to be drawn according to the length of the frame. The drawn fixture drawing is then pasted onto the wooden board, which is either lengthened or shortened according to the dimensions. Holes are drilled in the wooden board according to the installation positions of the jigs in the fixture drawing. Finally, nuts are used to secure the wire support.

[0003] Currently, most wire harness production tooling plates on the market are fixed to the support frame with bolts. When they need to be flipped over, the bolts need to be removed, the tooling plate needs to be flipped over, and then the tooling plate needs to be fixed with bolts again, which is very troublesome and affects production efficiency.

[0004] Therefore, we propose a flip-over tooling plate for wire harness production lines to solve the problems mentioned above. Utility Model Content

[0032] Embodiments of this utility model:

[0033] like Figures 1-9 As shown, this utility model provides a flipping fixture plate for a wire harness production line, including: a production line device, a transmission mechanism, a worm gear mechanism, a pedal control mechanism, and a meshing rack mechanism. Multiple supports 1 are arranged around the production line device, and a fixture plate 2 is mounted on each support 1. The fixture plate 2 rotates through the production line device. The production line device includes a frame 5, with a motor 6 and a connecting shaft 7 respectively mounted at both ends. A drive shaft 8 is connected to the motor 6, a first sprocket 9 is mounted at the top of the drive shaft 8, and a second sprocket 10 is mounted at the top of the connecting shaft 7. The first sprocket 9 and the second sprocket 10 are equipped with... The bracket 1 includes a frame 101 with a first transmission chain 11. Support rods 102 are symmetrically arranged on the frame 101. A rotating shaft 12 rotatably connected to the support rods 102 is provided in the tooling plate 2. A connecting plate 30 is provided on the side of the frame 101. Multiple connecting columns 31 are connected to the first transmission chain 11. The connecting plate 30 has a sleeve hole for engaging with the connecting column 31. Through the cooperation between the connecting plate 30 and the sleeve, the frame 101 can move along with the first transmission chain 11, driving the tooling plate 2 to move. The support rods 102 are provided with bearings 35, and the bearings 35 are interference-fitted with the rotating shaft 12.

[0034] like Figures 1-9As shown, the transmission mechanism is mounted on the support 1. The transmission mechanism includes a third sprocket 13, a fourth sprocket 14, and a rotating rod 15. The rotating rod 15 is rotatably connected to the support 1. The third sprocket 13 is sleeved on the rotating rod 15, and a transmission gear 16 is sleeved on the rotating rod 15. The fourth sprocket 14 is sleeved on the transmission shaft 3, and a second transmission chain 17 is provided on the fourth sprocket 14 and the third sprocket 13. The worm gear mechanism is mounted on the side of the support 1. A protective shell 36 for protecting the worm gear mechanism is provided on the side of the support 1. The worm gear mechanism is connected to the transmission mechanism by the transmission shaft 3. The worm gear mechanism includes a meshing worm wheel 18 and a worm 19. The worm wheel 18 is sleeved on the rotating shaft 12, and the worm 19 is connected to the transmission shaft 3. Through this arrangement, the transmission mechanism and the worm gear mechanism can be linked together.

[0035] like Figures 1-9 As shown, the pedal control mechanism is located at the bottom of the assembly line device. The pedal control mechanism includes a rod 20 hinged to the device frame 5 and a fixed plate 21 fixed within the device frame 5. A pedal 22 and an execution plate 23 are respectively located at both ends of the rod 20. A mechanism spring 24 is fixed between the execution plate 23 and the fixed plate 21. A gear meshing mechanism is installed on the assembly line device. A pull wire 4 is installed between the gear meshing mechanism and the pedal control mechanism. The gear meshing mechanism includes a U-shaped plate 25 fixed within the device frame 5. Symmetrical limiting posts 26 are fixed between the inner side of the U-shaped plate 25 and the device frame 5. Limiting plates 27 are slidably connected to the two limiting posts 26. A rack 28 is connected to the bottom of plate 27, and a compression spring 29 is sleeved on the limiting post 26. One end of the pull line 4 passes through the U-shaped plate 25 and is connected to the limiting plate 27, and the other end of the pull line 4 passes through the fixing plate 21 and is connected to the execution plate 23. It is worth mentioning that the spring coefficient of the mechanism spring 24 is greater than that of the compression spring 29. When the pedal 22 of the pedal control mechanism is stepped on, the rod 20 rotates, the execution plate 23 moves upward to compress the mechanism spring 24, and then the limiting plate 27 will drive the rack 28 to move under the action of the compression spring 29 and be pushed out of the device frame 5 to mesh with the moving transmission gear 16.

[0036] like Figures 1-9 As shown, the bottom of the frame 101 is provided with a plurality of ball bearings 32, and the outer side of the device frame 5 is provided with an annular plate 33 for supporting the bracket 1 and the tooling plate 2. The lower surface of the annular plate 33 is provided with a support leg 34. The ball bearings 32 are in contact with the annular plate 33. With this arrangement, the annular plate 33 can support the bracket 1 and the tooling plate 2, and the ball bearings 32 can also reduce friction.

[0037] Specifically, by starting the motor 6, the first transmission chain 11 is driven to rotate through the cooperation of the drive shaft 8, the first sprocket 9, the connecting shaft 7, and the second sprocket 10. Through the cooperation of the connecting plate 30 and the sleeve column, the frame 101 and the tooling plate 2 move with the rotation of the first transmission chain 11. When it is necessary to flip the tooling plate 2, simply step on the pedal 22 of the pedal control mechanism. The lever 20 will rotate around the hinge point, and then the actuator plate 23 will move upward to compress the mechanism spring 24. Then, the limit plate 27 will move under the action of the compression spring 29, driving the rack 28 to move and be pushed out of the device frame. 5. Then, the moving transmission gear 16 will mesh with the rack 28. Under the meshing transmission, the third sprocket 13 will rotate and cooperate with the second transmission chain 17 to drive the fourth sprocket 14 and the transmission shaft 3 to rotate. The transmission shaft 3 will drive the worm 19 to rotate. With the cooperation of the worm wheel 18, the tooling plate 2 will rotate through the rotating shaft 12. When it is not necessary to flip, simply release the pedal 22, the mechanism spring 24 will return to its original state, and the limit plate 27 and the rack 28 will be moved by the pull line 4 to enter the device frame 5, disengage from the movement trajectory line of the transmission gear 16, and not make contact, so that the tooling plate 2 is not flipped.
