[0029] The utility model is further described below in conjunction with the accompanying drawings:

[0030] like Figure 1 — Fig.10As shown, a tooling fixture for manufacturing a wire harness comprises a base 101, a reeling assembly is installed on the base 101, a cutting mechanism is arranged on the top of the base 101, the cutting mechanism comprises a cutting frame 201, a connecting mechanism is connected to the cutting frame 201 by bolts, a guiding mechanism is installed on the connecting mechanism, a winding mechanism is arranged in the connecting mechanism, the winding mechanism comprises a moving seat 501 that moves forward and backward, a plurality of rotating seats 502 arranged in a straight line are rotatably connected to the moving seat 501, and the plurality of rotating seats 502 are arranged to cut multiple strands of wire harnesses at one time, thereby improving processing efficiency, and rotating A slide groove 503 is provided on the top of the seat 502, and two symmetrically arranged clamping blocks 504 are slidably connected in the slide groove 503. A bidirectional screw rod 505 is rotatably connected to the rotating seat 502, and the bidirectional screw rod 505 is threadedly connected to the two clamping blocks 504. A clamping shaft 506 is bolted to the top of the clamping block 504, and the guiding mechanism includes two guide rollers 401 arranged up and down. The guide rollers 401 can fix the position of multiple wire harnesses so that the length of the clamping shaft 506 when pulling out the wire harness and winding the wire harness is equal each time, thereby ensuring the length of the wire harness cut each time and avoiding human errors.

[0031] In this embodiment, the connecting mechanism includes a plurality of groups of relatively arranged connecting frames 301, which are connected to the front and rear sides of the cutting frame 201 by bolts. A guide rod 302 is connected to one group of connecting frames 301 by bolts, and a driving screw rod 303 is rotatably connected to the other group of connecting frames 301. A No. 1 motor 304 for driving the driving screw rod 303 to rotate is connected to the top of the base 101 by bolts. The guide rod 302 and the driving screw rod 303 pass through the inner side of the cutting frame 201, and the movable seat 501 is slidably connected to the guide rod 302 and is threadedly connected to the driving screw rod 303. When the No. 1 motor 304 drives the driving screw rod 303 to rotate, the driving screw rod 303 drives the movable seat 501 to pass through the inside of the cutting frame 201, and the free end of the wiring harness is pulled from the front side of the cutting frame 201 to the rear side, which is convenient for cutting. In addition, by setting a rotatable clamping shaft 506, the volume of the device is greatly reduced, the device as a whole is more compact, the floor space is reduced, and the staff can operate it more labor-saving.

[0032] In this embodiment, a second motor 507 is connected to the movable seat 501 by bolts, and the output end of the second motor 507 is connected to a driving shaft 508 through a coupling. A plurality of first bevel gears 509 are welded on the driving shaft 508, and each first bevel gear 509 is respectively meshed with a second bevel gear 510. The second bevel gear 510 is connected to the middle position of the bottom of the rotating seat 502 by bolts. The rotation of the second motor 507 drives the driving shaft 508 to rotate, and the driving shaft 508 drives the first bevel gear 509 to rotate. The first bevel gear 509 drives a plurality of second bevel gears 510 to rotate, and the second bevel gear 510 drives a plurality of rotating seats 502 to rotate at the same time, so that the wiring harness fixed on the inner side of the two clamping shafts 506 is wound around the clamping shaft 506 with the midpoint of the rotating seat 502 as the axis, so that the cutting length of each strand of the wiring harness is consistent.

[0033] In this embodiment, a guide roller 401 is connected to a connecting block 402 on both sides through bearings, and a sliding rod 403 is slidably connected in the connecting block 402. The bottom of the sliding rod 403 is connected to a limiting block 404 by bolts. A spring 405 is sleeved on the sliding rod 403, and the spring 405 is arranged between the connecting block 402 and the connecting frame 301. The spring 405 is always in a compressed state. The top of the sliding rod 403 passes through the connecting frame 301 and is threadedly connected with a threaded sleeve 406. The threaded sleeve 406 is connected to the top of the connecting frame 301 through a bearing. The setting of the spring 405 can apply appropriate downward pressure to the upper guide roller 401 to avoid sliding between the guide roller 401 and the wiring harness and can pull the guide roller 401 to rotate when the wiring harness moves. The setting of the threaded sleeve 406 can lift the sliding rod 403 upward, thereby moving the upper guide roller 401 upward, making it convenient for the staff to pass the wiring harness from the front side of the guide roller 401 to the rear side.

[0034] In this embodiment, one end of the guide roller 401 away from the connecting block 402 is connected to the rotating block 407 by bolts, and a counter 408 is arranged on the rotating block 407. The counter 408 is connected to the side of the connecting frame 301 by bolts, and the counter 408 is used to count the number of rotations of the guide roller 401. Since no sliding occurs between the guide roller 401 and the wire harness during pulling out, the pulling length of the wire harness can be determined by the number of rotations of the guide roller 401, thereby controlling the length of each cutting of the wire harness, making the length of each cutting of multiple strands of the wire harness consistent, and avoiding artificial errors.

[0035] In this embodiment, the top of the cutting frame 201 is connected to the cylinder 203 by bolts, and the output end of the cylinder 203 is connected to the cutter 204 by bolts. A storage groove 202 for completely storing the cutter 204 is opened at the inner side of the top of the cutting frame 201, and a cutting groove 205 is opened at the bottom of the cutting frame 201. In the process of the moving seat 501 pulling out the wire harness, the cutter 204 is completely inside the storage groove 202, which facilitates the forward and backward translation movement of the moving seat 501, and at the same time prevents the staff from touching the cutter 204 and being injured, thereby improving the safety of use.

[0036] In this embodiment, the unwinding assembly includes a column 102, which is rotatably connected to a mounting roller 103, and a plurality of unwinding wheels 104 are mounted on the mounting roller 103. The number of unwinding wheels 104 corresponds to the number of rotating seats 502. The unwinding wheels 104 are plugged into the mounting roller 103 to facilitate loading and unloading and improve processing efficiency.

[0037] Working principle: Before using the device, the unwinding wheel 104 with the wire harness to be processed is plugged into the installation roller 103. The staff rotates the threaded sleeve 406 to increase the distance between the two guide rollers 401. Then, the ends of the wire harness are passed from the front side to the back side of the guide roller 401 one by one. Then, the threaded sleeve 406 is rotated in the opposite direction to make the two guide rollers 401 close to each other and exert a certain pressure on the wire harness to prevent relative sliding. Then, the No. 1 motor 304 is used to drive the screw rod 303 to rotate, so that the moving seat 501 is close to the guide roller. 401, put the free end of each wire harness between the clamping shafts 506 and rotate the bidirectional screw 505 to make each clamping shaft 506 clamp the wire harness. After each wire harness is fixed, use the No. 1 motor 304 to drive the screw 303 to rotate in the opposite direction, and the moving seat 501 passes through the cutting frame 201 and moves backward. During the movement, the wire harness is pulled out, and the middle section of the wire harness drives the guide roller 401 to rotate, and the lower guide roller 401 drives the rotating block 407 to rotate. The counter 408 can record the number of rotations to control the cutting length of the wire harness;

[0038] After the moving seat 501 moves to the rearmost position, the No. 1 motor 304 pauses, the second motor 507 starts, the second motor 507 drives the driving shaft 508 to rotate, the driving shaft 508 drives the first bevel gear 509 to rotate, the first bevel gear 509 drives a plurality of second bevel gears 510 to rotate, and the second bevel gear 510 drives a plurality of rotating seats 502 to rotate at the same time, so that the wire harness fixed on the inner side of the two clamping shafts 506 is wound around the clamping shaft 506 with the midpoint of the rotating seat 502 as the axis, so that the cutting length of each wire harness is consistent. When the guide roller 401 drives the rotating block 407 to rotate a certain number of circles, the length of the pulled wire harness reaches the planned length, the second motor 507 stops, and the cylinder 203 pushes the cutter 204 to move downward, and the cutter 204 cuts the upper part of the cutting groove 205 The wire harness at the position is cut to obtain multiple wire harnesses of the same length. At this time, the staff rotates the bidirectional screw rod 505 to loosen the clamping shaft 506, pulls out the wire harness wound on the clamping shaft 506 upward, collects the rolled wire harness, and completes a cutting process. Then, the No. 1 motor 304 is started, and the No. 1 motor 304 drives the driving screw rod 303 to move the movable seat 501 to the cutting frame 201 position. At this time, the free ends of the wire harnesses are aligned, and the length can be determined more accurately to avoid manual errors. Then the free end of the wire harness is clamped into the clamping shaft 506. During the process of placing the clamping shaft 506, the guide roller 401 is prevented from rotating. Repeat the above steps, and multiple wire harnesses of the same length can be obtained each time cutting, and the cutting length is easy to control, which is safe and convenient to use.
