[0040] Example 1

[0041] Reference Figures 1 to 6 , which is the first embodiment of the present invention, provides a bending and cutting device for automobile wiring harness terminals and a bending and cutting method thereof, the device comprises a bottom component 100, a cutting component 200 and a bending component 300, wherein the bottom component 100 comprises a base 101, a placement bin 102 arranged on the base 101, and a wire placement groove 103 opened on the base 101; the cutting component 200 is arranged on the base 101, and comprises a mounting frame 201, a through hole 202 opened on the mounting frame 201, an arc groove 203 and an oblique groove 204 opened on both sides of the through hole 202, a cutter 205 fitted with the mounting frame 201, and a limit rod 20 symmetrically opened on both sides of the cutter 205. 6. A handle 207 rotatably arranged on the mounting frame 201, a safety buckle 208 arranged on the top of the mounting frame 201; and a bending assembly 300, which is arranged next to the base 101, including vertical rods 301 arranged opposite to each other, a Y-shaped groove 302 opened on the vertical rods 301, a driving rod 303 rotatably connected to the two vertical rods 301, a support rod 304 fixedly arranged at both ends of the driving rod 303, a connecting rod 305 rotatably connected to the support rod 304, a pressure plate 306 rotatably connected to the connecting rod 305, a moving block 307 rotatably arranged on the pressure plate 306, a slider 308 slidably connected to the vertical rod 301, and a spring 309 arranged at the bottom of the slider 308.

[0042] Among them, a plurality of wiring harness terminals can be embedded in the placement bin 102; the wire placement groove 103 is evenly opened on the top surface of the base 101 and extends to the side wall, and the aperture of the wire placement groove 103 is the same as the aperture of the wiring harness. The mounting frame 201 is arranged between the placement bin 102 and the wire placement groove 103, the through hole 202 is the same size as the placement bin 102, the arc groove 203 is opened on one side of the through hole 202, and the arc groove 203 is a quarter circle, and the oblique groove 204 is opened on the other side of the through hole 202, and the oblique groove 204 is a straight line. The cutter 205 is in the shape of an elongated strip, and the cut surface of the cutter 205 is longer than the length of the through hole 202. The limit rods 206 are fixed at both ends of the cutter 205, and the limit rods 206 are respectively embedded in the arc groove 203 and the inclined groove 204. The handle 207 is L-shaped, and the end of the handle 207 is rotatably connected to the limit rod 206 set in the arc groove 203. A protrusion 207a is also set on the back of the handle 207. The safety buckle 208 is rotatably set on the mounting frame 201, and the protrusion 207a cooperates with the safety buckle 208 to resist each other.

[0043] During use, the automobile wiring harness terminal is inserted into the placement bin 102, and the terminal is fixed by the placement bin 102. There are many public technologies for arranging movable parts in the placement bin 102 to keep the terminal fixed, which will not be repeated here; the wiring harness of the connection terminal corresponds to the wiring groove 103 one by one, and the wiring harness can be embedded in the wiring groove 103. When the excess wiring harness is cut, it is only necessary to open the safety buckle 208. As can be seen from the figure, the safety buckle 208 can be lifted to release the fixation of the protrusion 207a on the back of the handle 207, that is, the handle 207 is movable, and the handle 207 is pulled down. 207 rotates, driving the limit rod 206 located in the arc groove 203 to move, causing one end of the cutter 205 to drop. When the cutter 205 moves to the right with the limit rod 206, the limit rod 206 in the inclined groove 204 on the other side is also pressed down to cut the wire harness in the through hole 202. After the cutting is completed, the handle 207 is reversed, and the cutter 205 returns to the initial state along the previous path. At the same time, the protrusion 207a on the back of the handle 207 is re-engaged in the safety buckle 208 to complete the fixation of the handle 207 and prevent the handle 207 from falling with gravity and causing accidental cutting.

[0044] Example 2

[0045] Reference Figures 1 to 13, which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: a slide bar 301a is provided on the side wall of the vertical rod 301, the Y-shaped groove 302 is composed of a straight line and an arc, the driving rod 303 passes through the two vertical rods 301, and a handle 303a is also provided in the center of the driving rod 303, and the support rod 304 is fixedly connected to the driving rod 303. One end of the connecting rod 305 is rotatably connected to the support rod 304, and the other end is rotatably connected to the cross bar 305a; the other end of the cross bar 305a is rotatably connected to the pressing plate 306. The cross bar 305a is embedded in the Y-shaped groove 302, and the initial position of the cross bar 305a is located at the top of the arc of the Y-shaped groove 302. The moving block 307 is embedded in the Y-shaped groove 302, and the initial position of the moving block 307 is located at the top of the straight line of the Y-shaped groove 302. The pressing plate 306 is disposed between the vertical rods 301, and the pressing plate 306 can fit the wire groove 103 on the side wall of the base 101. The slider 308 is slidably connected to the slide bar 301a, one end of the spring 309 is connected to the bottom of the vertical rod 301, and the other end is connected to the slider 308, and the slider 308 is against the pressing plate 306.

[0046] The bending and shearing method includes the following steps:

[0047] S1: inserting a plurality of wiring harness terminals into the placement chamber 102;

[0048] S2: Align and fit each wire harness with the wire slot 103;

[0049] S3: Rotate the handle 303a to make the pressing plate 306 squeeze the wire harness and bend the wire harness into the wire groove 103 on the side wall of the base 101;

[0050] S4: Press the handle 207 and use the cutter 205 to cut off the excess wire harness of the terminal.

[0051] Compared with Example 1, further, the bending operation on the excess wire harness can be performed before cutting. After the wire harness terminal is inserted into the placement bin 102 and fixed, one end of the wire harness is fixed, and the bending operation can be performed better. Preferably, the wire harness bending in this embodiment can be performed before cutting. After the wire harness and the wire placement slot 103 are arranged correspondingly, the handle 303a is rotated to drive the support rod 304 to rotate, so that the connecting rod 305 moves downward, that is, the cross bar 305a of the connecting rod 305 is located in the Y-shaped slot 302 and moves along the slot to the straight part. At this time, the cross bar 305a and the moving block 307 are in the same vertical straight slot, and the pressing plate 306 is rotated to a horizontal state, and the handle 303a is continued to be rotated, and the cross bar 305a is continued to be pressed down and moves downward along the straight line in the Y-shaped slot 302. At this time, the cross bar 305a and the moving block 307 move downward at the same time, driving the pressing plate 306 to move vertically downward The pressing plate 306 can be bent beyond the base 101 at this time, and squeezed into the wire slot 103. When the cross bar 305a moves to the bottom, the pressing plate 306 squeezes the slider 308 downward, that is, squeezes the spring 309, releases the grip 303a, the spring 309 is reset, and the slider 308 is pushed up. The preferred slider 308 can be trapezoidal, and the slider 308 pushes the pressing plate 306 against each other. When the moving block 307 is pushed to the top of the Y-shaped slot 302, the inclined surface of the slider 308 will push the cross bar 305a into the arc of the Y-shaped slot 302, or the cross bar 305a can be directly reset to the arc of the Y-shaped slot 302 by reversing the grip 303a, that is, the pressing plate 306 rotates from the horizontal to the initial state, the device is reset, and then the bent wire harness can be removed after the cutting operation, which is convenient for subsequent processing.

[0052] The remaining structures are the same as those of Example 1.

[0053] 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.
