Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0027] Please refer to Figure 1-8 A wire harness bending device 100 includes a frame 10, a mounting block 20 disposed on the frame 10, and a first fixing block 30 and a second fixing block 40 sequentially disposed on the mounting block 20, as well as a fixing mechanism 50 and a bending mechanism 60 disposed on the frame 10, wherein the fixing mechanism 50 is used to fix the first fixing block 30 and the second fixing block 40 on the mounting block 20, and the wire harness 200 is sequentially placed on the first fixing block 30 and the second fixing block 40 and bent by the bending mechanism 60.

[0028] The frame 10 is provided with a mounting groove 11 , and the mounting groove 11 is located at one side of the mounting block 20 .

[0029] The mounting block 20 is provided with a sliding groove 21 for the first fixing block 30 and the second fixing block 40 to slide, and the sliding groove 21 is provided with a threaded hole 3 211. The mounting block 20 is also provided with a threaded hole 4 22. The threaded hole 3 211 is arranged along the height direction of the mounting block 20, and the threaded hole 4 22 is arranged along the width direction of the mounting block 20. Specifically, a plurality of threaded holes 3 211 and threaded holes 4 22 are provided. For the convenience of illustrating the drawings corresponding to this embodiment, one threaded hole 3 211 and one threaded hole 4 22 are respectively shown for the first fixing block 30 and the second fixing block 40.

[0030] The first fixing block 30 and the second fixing block 40 are both slidably disposed in the sliding groove 21. The first fixing block 30 and the second fixing block 40 are both provided with a fixing groove 31 adapted to the wire harness. The first fixing block 30 is farther away from the bending mechanism 60 than the second fixing block 40. The fixing groove 31 on the first fixing block 30 and the fixing groove 31 on the second fixing block 40 are both provided with a limiting protrusion 311. When the wire harness is placed in the fixing groove 31, the limiting protrusion 311 is located above the wire harness 200 and the top of the wire harness 200 abuts against the limiting protrusion 311, so as to radially limit the wire harness 200, so that the wire harness 200 is not easily moved radially when being bent.

[0031] Specifically, in this embodiment, there is one first fixing block 30, three second fixing blocks 40, and the three second fixing blocks 40 are arranged in parallel along the length direction of the mounting block 20, the first fixing block 30 is provided with a threaded hole 1 32, and the second fixing block 40 is provided with a threaded hole 2 41.

[0032] The fixing mechanism 50 includes a first fixing screw 51 and a second fixing screw 52. The first fixing screw 51 is arranged along the height direction of the mounting block 20, and the second fixing screw 52 is arranged along the width direction of the mounting block 20. The first fixing screw 51 is adapted to the threaded hole 1 32, and the second fixing screw 52 is adapted to the threaded hole 2 41. The threaded hole 1 32 corresponds to the threaded hole 3 211, and the threaded hole 2 41 corresponds to the threaded hole 4 22. The first fixing screw 51 is threadedly connected to both the threaded hole 1 32 and the threaded hole 3 211. The second fixing screw 52 is threadedly connected to both the threaded hole 2 41 and the threaded hole 4 22.

[0033] The bending mechanism 60 includes a rotating disk 61 rotatably mounted on the frame 10, a driving assembly 62 for driving the rotating disk 61 to rotate, and a clamping claw 63 for clamping the wire harness. The rotating disk 61 is located on one side of the mounting block 20, and the clamping claw 63 is adapted to the wire harness. The rotating disk 61 is provided with a rotating shaft 611 coaxially arranged with the rotating disk 61.

[0034] The driving assembly 62 includes a rotating motor 621 for driving the rotating disk 61 to rotate, a moving block 622 connected to the rotating disk 61, and a telescopic cylinder 623 arranged on the moving block 622. The rotating motor 621 is arranged on the frame 10, and the rotating motor 621 is located on one side of the rotating disk 61. A moving groove 6221 for the clamping claw 63 to move is provided on the moving block 622. The moving block 622 also has a through hole (not numbered in the figure) connected to the moving groove 622. The size of the through hole is smaller than the size of the moving groove 622. The piston rod of the telescopic cylinder 623 passes through the through hole. The piston rod of the telescopic cylinder 623 is connected to the clamping claw 63, and the clamping claw 63 moves back and forth in the moving groove 6221 through the telescopic cylinder 623. Specifically, in this embodiment, the rotating motor 621 and the telescopic cylinder 623 are electrically connected to the corresponding controller and control switch 1 627 and control switch 2 628 for manual control, wherein control switch 1 627 is used to control the rotating motor 621, and control switch 2 628 is used to control the telescopic cylinder 623. The controller, control switch 1 627 and control switch 2 628 are all existing technologies, and the controller is not shown in the figure.

[0035] The driving assembly 62 also includes a first bevel gear 624, a second bevel gear 625 and a synchronous toothed belt 626. The first bevel gear 624 is sleeved on the rotating shaft 611 and is coaxially fixed with the rotating shaft 611. The second bevel gear 625 is sleeved on the output shaft of the rotating motor 621 and is coaxially fixed with the output shaft of the rotating motor 621. The synchronous toothed belt 626 is meshed with the first bevel gear 624 and the second bevel gear 625. The arrangement of the first bevel gear 624, the second bevel gear 625 and the synchronous toothed belt 626 facilitates the placement of the rotating motor 621 on the frame 10. When the rotating motor 621 is started, the rotating motor 621 drives the second bevel gear 625 to rotate, the second bevel gear 625 drives the first bevel gear 624 to rotate through the synchronous toothed belt 626, and the first bevel gear 624 drives the rotating shaft 611 to rotate.

[0036] The working principle of a wire harness bending device 100 provided by the utility model is as follows: before bending, the first fixing block 30 and the second fixing block 40 are moved respectively, so that the positions of the first fixing block 30 and the second fixing block 40 relative to the mounting block 20 can be adapted to the length of the wire harness 200. After being moved to a suitable position, the first fixing screw 51 is sequentially passed through the threaded hole 1 32 on the first fixing block 30 and the threaded hole 3 211 on the mounting block 20 and tightened, and the second fixing screw 52 is sequentially passed through the threaded hole 2 41 on the second fixing block 40 and the threaded hole 4 22 on the mounting block 20 and tightened, so that the first fixing block 30 and the second fixing block 40 are both fixed on the mounting block 20, and then the wire harness 200 is sequentially inserted into the fixing grooves 31 on the first fixing block 30 and the second fixing block 40 and placed, and the limiting protrusions 311 on the fixing grooves 31 limit the wire harness 200 radially.

[0037] When bending, the telescopic cylinder 623 is started to expose the clamping claw 63 from the moving groove 6221, and the part of the wire harness 200 that needs to be bent is clamped by the clamping claw 63, and then the rotating motor is started, so that the rotating disk 61 drives the part of the wire harness 200 that needs to be bent to rotate, that is, the wire harness 200 is bent.

[0038] Beneficial effect: When the wire harness 200 is bent, the wire harness 200 is placed on the mounting block 20 and the clamping jaw 63 in sequence, and the rotating motor 621 drives the rotating disk 61 to drive the clamping jaw 63 to rotate, thereby bending the wire harness 200. In this way, the bending of the wire harness 200 can be completed when the room temperature is low and the sheathing layer of the wire harness is relatively hard. Compared with manual bending, the bending process driven by the rotating motor is more labor-saving, and the efficiency of bending the wire harness 200 is improved.
