[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This wiring harness positioning device for automotive wiring harness production, through the cooperation of a servo motor, coupling, transmission screw, and sliding screw block, can precisely control the lifting and lowering of the positioning base. The stable output of the servo motor drives the transmission screw to rotate, causing the sliding screw block to move smoothly along the limit slide groove, thereby achieving precise adjustment of the positioning base height. This solves the problem that existing technologies can only perform fixed height positioning. Operators can conveniently adjust the positioning height of the wiring harness according to different processing procedures, greatly improving the flexibility and applicability of the device.

[0017] 2. This automotive wiring harness positioning device uses an electric push rod on a U-shaped bracket to push the positioning plate downwards, which tightly presses the wiring harness into the positioning arc groove of the positioning base. Combined with the anti-slip rubber pad at the bottom of the positioning plate, it effectively prevents the wiring harness from sliding or shifting during processing. The design of the positioning arc groove conforms to the shape of the wiring harness, further improving positioning stability and ensuring that the wiring harness remains fixed during various processing operations, reducing processing errors caused by wiring harness displacement, thereby guaranteeing the production quality of automotive wiring harnesses.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-4 This utility model provides a technical solution: a wire harness positioning device for automotive wire harness production, including a counterweight base 1, mounting brackets 2 are fixedly installed on the two sides of the top of the counterweight base 1 that are far apart, and an adjustment limiting mechanism 3 is provided in the middle of the mounting brackets 2.

[0025] The adjusting limit mechanism 3 includes a limit groove 301. Limit grooves 301 are formed on both sides of the mounting bracket 2. A servo motor 302 is fixedly mounted on the top of the mounting bracket 2. A coupling 303 is fixedly mounted on the output end of the servo motor 302. The coupling 303 extends into the interior of the limit groove 301. A transmission screw 304 is fixedly mounted on the bottom end of the coupling 303. A support bearing seat 305 is fixedly mounted on the inner wall of the bottom end of the limit groove 301. The bottom end of the transmission screw 304 is fixedly connected to the interior of the support bearing seat 305. The outer end of the transmission screw 304 is threadedly connected to... A sliding screw block 306 is provided, and support connecting blocks 307 are fixedly installed on both sides of the sliding screw block 306. A positioning base 308 is fixedly installed in the middle of the support connecting block 307. The top of the positioning base 308 is provided with several positioning arc-shaped grooves 309. The servo motor 302 is started and drives the transmission screw 304 to rotate through the coupling 303. When the transmission screw 304 rotates, the sliding screw block 306, which is threaded to it, moves linearly up and down along the transmission screw 304 under the guidance of the limiting slide groove 301, and then drives the positioning base 308 to move up and down synchronously through the support connecting block 307.

[0026] A U-shaped bracket 4 is fixedly installed at the top of the positioning base 308. Electric push rods 5 are fixedly installed on both sides of the top of the U-shaped bracket 4. A push rod 6 is fixedly installed at the output end of the electric push rod 5. The push rod 6 extends to the bottom end of the U-shaped bracket 4. A positioning pressure plate 7 is fixedly installed at the bottom end of the push rod 6. An anti-slip rubber pad 8 is fixedly installed at the bottom end of the positioning pressure plate 7. Several mounting screw holes 9 are evenly opened at the top of the counterweight base 1. The mounting screw holes 9 penetrate the counterweight base 1. A PLC controller 10 is fixedly installed on one side of the top of the counterweight base 1. The PLC controller 10 is electrically connected to the servo motor 302 and the electric push rod 5. When the electric push rod 5 is started, the electric push rod 5 pushes the push rod 6 downward, causing the positioning pressure plate 7 and the anti-slip rubber pad 8 to move downward synchronously.

[0027] Working Principle: When this automotive wiring harness positioning device is needed, it is first installed stably in the required position using bolts through the mounting screw holes 9 on the counterweight base 1. An external power supply is then connected to power all components on the device. The operator sets the target height of the positioning base 308 according to the specific processing requirements via the PLC controller 10. The PLC controller 10 sends a command to the servo motor 302, which starts and drives the transmission screw 304 to rotate via the coupling 303. Since the bottom end of the transmission screw 304 is fixed in the support bearing seat 305, its rotation is stable and without deviation. When the transmission screw 304 rotates, the sliding screw block 306, which is threaded to it, moves linearly up and down along the transmission screw 304 under the guidance of the limit groove 301, and then through the support connecting block 307... The positioning base 308 is raised and lowered synchronously until it reaches the preset height. At this point, the servo motor 302 stops working, and the positioning base 308 completes the height positioning. Then, the operator places the automotive wiring harness to be processed into the positioning arc groove 309 at the top of the positioning base 308. The positioning arc groove 309 conforms to the shape of the wiring harness, initially limiting the horizontal displacement of the wiring harness. Next, the electric push rod 5 is started by the PLC controller 10. The electric push rod 5 pushes the push rod 6 to extend downward, causing the positioning pressure plate 7 to move downward synchronously. When the anti-slip rubber pad 8 at the bottom of the positioning pressure plate 7 contacts the surface of the wiring harness and applies a certain pressure, the PLC controller 10 controls the electric push rod 5 to stop extending. At this time, the wiring harness is tightly clamped between the positioning arc groove 309 and the positioning pressure plate 7. The anti-slip rubber pad 8 further increases the friction, effectively preventing the wiring harness from sliding or rotating during processing.

[0028] Finally, it should be noted that the above content is only used to illustrate the technical solution of this utility model, and is not intended to limit the scope of protection of this utility model. Simple modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model do not depart from the essence and scope of the technical solution of this utility model.
