[0032] Example 1

[0033] Reference Figures 1 to 9, which is the first embodiment of the present invention, provides an automobile wire harness bending device, which includes a driving component 100, a flip component 200 and a clamping component 300. The driving component 100 includes a base 101, a sliding frame 102 arranged on the base 101, a mounting frame 103 arranged on one side of the base 101, a motor 104 fixedly arranged on the mounting frame 103, a sprocket 105 connected to the motor 104, a chain 106 sleeved outside the sprocket 105, a slider 107 fixed to the chain 106, a vertical groove 108 fixedly arranged on the slider 107, and a limiting rod 109 embedded in the vertical groove 108; the flip component 200 includes a flat plate 201 fixedly connected to the limiting rod 109, a fixed Rollers 202 are fixedly arranged at the four corners of the flat plate 201, a counterweight block 203 is arranged at the bottom of the flat plate 201, and wire grooves 204 are symmetrically arranged on both sides of the sliding frame 102; and a wire clamping assembly 300 is symmetrically arranged at both ends of the flat plate 201, including a fixing frame 301 vertically arranged on the flat plate 201, a through hole 302 opened on the fixing frame 301, a fastening bolt 303 threadedly connected to the fixing frame 301, a transmission block 304 slidingly connected to the fixing frame 301, connecting rods 305 symmetrically arranged on both sides of the bottom of the transmission block 304, a pressure block 306 rotatably connected to the connecting rod 305, an extrusion rod 307 arranged at the bottom of the connecting rod 305, and a spring 308 sleeved on the outside of the extrusion rod 307.

[0034] The sliding frame 102 has linear slide grooves 102a on both sides, and the slide grooves 102a are semi-open structures with an open top. The mounting frame 103 is arranged on one side of the sliding frame 102. The output shaft of the motor 104 is fixedly connected to a sprocket 105. Two sprockets 105 are provided, and the sprockets 105 are symmetrically arranged on both sides of the mounting frame 103. The chain 106 is sleeved outside the two sprockets 105. The mounting frame 103 also has a slideway 103a, and the slider 107 is embedded in the slideway 103a. The vertical groove 108 is vertically fixed on the slider 107. The length of the flat plate 201 is less than the length of the slide groove 102a. The limiting rod 109 is vertically fixed on one side of the flat plate 201 close to the mounting frame 103, and the top of the limiting rod 109 is embedded in the vertical groove 108; the roller 202 is arranged in the slide groove 102a, and the wire placement groove 204 corresponds to the extrusion rod 307 one by one. A notch 302a is provided on one side of the through hole 302, and the transmission block 304 is provided at the bottom of the fastening bolt 303. The connecting rod 305 includes two supporting rods, one supporting rod is a single disc, and the pressure block 306 is rotatably connected to the other supporting rod. The pressure block 306 is two discs, and the supporting rods for fixing the single discs on the two connecting rods 305 are staggered. The extrusion rod 307 corresponds to the discs on the connecting rod 305 one by one, and the extrusion rod 307 passes through the fixing frame 301, and the extrusion rod 307 is slidably arranged with the fixing frame 301. The through hole 302 is provided at the bottom of the extrusion rod 307. The spring 308 is sleeved on the outside of each extrusion rod 307. One end of the spring 308 is fixedly connected to the top of the extrusion rod 307, and the other end is fixedly connected to the fixing frame 301.

[0035] During use, first of all, according to the number of times the wire harness needs to be bent, the operation process of bending once is also included in bending twice. The process of bending the wire harness only once will not be repeated here. Taking bending twice as an example, the wire harness is placed through the through hole 302, and the fastening bolt 303 is screwed. The fastening bolt 303 moves down and pushes the transmission block 304 at the bottom. The transmission block 304 is pressed down to press the connecting rod 305 down, so that the extrusion rod 307 clamps the wire harness in the through hole 302. It should be noted that when the wire harnesses are of different thicknesses, the transmission block 304 is pressed down, and the connecting rod 307 is clamped. The upper disc of one of the supporting rods 305 touches the bottom first, clamping the thicker wire harness. The connecting rod 305 continues to be pressed down, which will cause the connecting rod 305 to rotate, and the disc of the thinner wire harness at the other end will continue to be pressed down and clamped. The same is true for the pressing block 306. After one disc clamps the thicker wire harness, the pressing block 306 will rotate a certain angle, and the top disc of the thinner wire harness will continue to be pressed down until all the wire harnesses are clamped and fixed; the spring 308 outside the squeezing rod 307 can reset all the squeezing rods 307 and ensure that the transmission block 304 is against the fastening bolt 303.

[0036] For bending twice, it is necessary to clamp the two bending points of the wire harness, so the wire clamping components 300 at both ends of the flat plate 201 need to fix the wire harness. After fixing, start the motor 104, and the motor 104 can rotate the sprocket 105, driving the chain 106 to move, and the slider 107 is fixed on the chain 106, and the slider 107 can move in the slide 103a. First, taking from left to right as an example, the slider 107 drives the vertical slot 108 to move from left to right. Since the length of the flat plate 201 is less than the slide slot 102a, the vertical slot 108 can push the flat plate 201 through the limit rod 109. When the roller 202 at one end of the flat plate 201 hits the end of the slide slot 102a, the slider 107 continues to move, which will cause the flat plate 201 to gradually flip over. The top of 102a is not closed, and the other end of the flat plate 201 can be gradually lifted. When the slider 107 moves to the other end of the slide 103a, the motor 104 stops rotating. At this time, the flat plate 201 is turned over 90 degrees, and the wiring harness is also bent 90 degrees. Then the motor 104 reverses to make the chain 106 move in the opposite direction. At this time, the slider 107 moves from right to left, and the flat plate 201 is gradually laid flat and pushed by the vertical groove 108 to the leftmost side of the slide 102a. The slider 107 continues to move, and the flat plate 201 is turned over again. At this time, the leftmost end of the flat plate 201 is used as the bending point, and the wiring harness is bent 90 degrees again. The two ends of the wiring harness complete two bends, and then the fastening bolts 303 are loosened, the wiring harness is not fixed, and is discharged from the gap 302a.

[0037] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
