It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the present invention.

[0024] Example 1

[0025] A cutting device for automobile wiring harness connectors, such as Figure 1-9As shown, it includes a handle 1, a servo motor 2 is fixedly connected to one side of the handle 1, a start button 1 31 is fixedly connected to the handle 1, and the start button 1 31 is used to control the output shaft of the servo motor 2 to rotate clockwise, a start button 2 32 is fixedly connected to the handle 1, and the start button 2 32 is used to control the output shaft of the servo motor 2 to rotate counterclockwise, a support mechanism is provided on the side of the handle 1 close to the servo motor 2, and the support mechanism is used to support the limit wiring harness connector, and a tangent mechanism is provided on the support mechanism, and the tangent mechanism is used to cut the wiring harness connector.

[0026] The supporting mechanism includes a supporting base frame 41, which is fixedly connected to a side of the handle 1 close to the servo motor 2, and two vertical plates 42 are fixedly connected to one side of the supporting base frame 41, and the two vertical plates 42 are connected to the handle 1, and limiting columns 43 are fixedly connected to both sides of the supporting base frame 41, and a bent plate 44 is fixedly connected between the upper parts of the two vertical plates 42, and a threaded rod 45 is rotatably connected to the bent plate 44, and a threaded block 46 is threadedly connected to the threaded rod 45, and a transmission gear 47 is fixedly connected to the upper end of the threaded rod 45, and a driving gear 48 is fixedly connected to the output shaft of the servo motor 2, and the driving gear 48 is meshed with the transmission gear 47.

[0027] The tangent mechanism includes two pressing plates 51, and the two pressing plates 51 are slidably connected to the two vertical plates 42 respectively. A connecting plate 52 is fixedly connected between the two pressing plates 51, and a connecting frame 53 is slidably connected to the connecting plate 52. The lower part of the connecting frame 53 is connected to the threaded block 46, and a reset spring 54 is connected between the connecting frame 53 and the connecting plate 52. A limiting frame 55 is fixedly connected to the side of the connecting frame 53 away from the threaded block 46, and a cutter 56 is slidably connected to the limiting frame 55. A positioning frame 57 is fixedly connected between the two pressing plates 51, a serrated plate 1 58 is fixedly connected to the cutter 56, a serrated plate 2 59 is fixedly connected to the cutter 56, and the positioning frame 57 is located between the serrated plate 1 58 and the serrated plate 2 59.

[0028] In the actual process of wiring harness for automobiles, operators need to connect various types of already installed harnesses. In the process of connecting harnesses, operators are often required to reasonably cut harness connectors for the sake of aesthetics of assembly and rationality of routing. After cutting off the connector part of the harness, operators first put the harness to be cut between the support frame 41 and the pressing plate 51. Operators then hold the handle 1 and press the start button 31. The start button 31 controls the output shaft of the servo motor 2 to rotate clockwise, and then the servo motor 2 rotates clockwise. The output shaft of the machine 2 rotates clockwise to drive the driving gear 48 to rotate, and then drives the transmission gear 47 to rotate counterclockwise. The transmission gear 47 rotates counterclockwise to drive the threaded rod 45 to rotate together. The threaded rod 45 rotates counterclockwise to drive the threaded block 46 to move downward. The downward movement of the threaded block 46 drives the connecting frame 53, the limit frame 55 and the cutter 56 to move downward together. The downward movement of the connecting frame 53 drives the pressure plate 51 to move downward together through the return spring 54. After the pressure plate 51 moves downward for a distance, it contacts the wire harness and stops moving downward. The positioning frame 57 also stops moving downward, and then the connecting frame 53 and the cutter 56 continue to move downward, the reset spring 54 is compressed, so that the two pressure plates 51 clamp and limit the wiring harness, and the sawtooth plate 1 58 and the sawtooth plate 2 59 also move downward together. The downward movement of the sawtooth plate 1 58 and the sawtooth plate 2 59 will squeeze the positioning frame 57 to move horizontally back and forth, and the horizontal reciprocating movement of the positioning frame 57 will drive the cutter 56 to move horizontally back and forth together, so that the cutter 56 will move horizontally back and forth while moving downward, and the cutter 56 continues to move downward and reciprocate horizontally. The wire harness will be cut. When the threaded rod 45 stops rotating counterclockwise, the cutter 56 stops moving downward and cuts the wire harness. Then the operator presses the start button 32 again. The start button 32 controls the output shaft of the servo motor 2 to rotate counterclockwise, and then drives the threaded rod 45 to rotate clockwise through the driving gear 48 and the transmission gear 47, and finally drives the threaded block 46 and the cutter 56 to reset upward, thus completing the cutting of the wire harness. When cutting the wire harness connector, the wire harness is first clamped and limited, and then cut, which can make the cutting more stable.

[0029] Example 2

[0030] On the basis of Example 1, Figure 6-8As shown, it also includes a folding mechanism, which is arranged on the support frame 41, and is used to fold the wire harness. The folding mechanism includes two fixed side rods 61, and the two fixed side rods 61 are respectively fixedly connected to the two sides of the support frame 41, and the two fixed side rods 61 are both sleeved with a rotating ring 62, and the rotating ring 62 has a spiral groove. The two fixed side rods 61 are connected to a connecting spring 63, and one side of the connecting spring 63 is in contact with the rotating ring 62. The two rotating rings 62 A folding plate 64 is fixedly connected to one side, and side blocks 65 are fixedly connected to both sides of the support base frame 41. Pulling frames 66 are slidably connected to the two side blocks 65. A protrusion is provided on one side of the pulling frame 66. One side of the pulling frame 66 is sleeved on the rotating ring 62. The protrusion of the pulling frame 66 cooperates with the spiral groove on the rotating ring 62. A guide frame 67 is fixedly connected to one side of the two pressure plates 51. The guide frame 67 has a guide groove, and the upper part of the pulling frame 66 is located in the guide groove on the guide frame 67.

[0031] When the two pressure plates 51 move downward to clamp the wiring harness, the downward movement of the two pressure plates 51 will drive the guide frame 67 to move downward, and the downward movement of the guide frame 67 will squeeze the pulling frame 66 to move horizontally in the direction close to the handle 1. The horizontal movement of the pulling frame 66 will first drive the rotating ring 62 to rotate 180° through the cooperation of the protrusion and the spiral groove, and the rotating ring 62 rotating 180° will drive the retracting plate 64 to rotate upward 180°, and then the pulling frame 66 continues to move horizontally to drive the rotating ring 62 to move horizontally together, the connecting spring 63 is compressed, and the rotating ring 62 and the pulling frame 66 move horizontally together in the direction close to the handle 1, which will drive the retracting plate 64 to move horizontally together, and the retracting plate 64 moves horizontally in the direction close to the handle 1 to squeeze and retract the wiring harness in the direction close to the limit column 43. In this way, the wiring harness can be more concentrated and aligned when cut, and it is not easy to have inconsistent cutting lengths of each wire in the wiring harness.

[0032] Example 3

[0033] On the basis of Example 2, Fig. 9As shown, it also includes a clamping mechanism, which is arranged on the supporting base frame 41, and is used to clamp the cut wire harness, and the clamping mechanism includes two sliding blocks 71, and the two sliding blocks 71 are respectively slidably connected to the two limiting columns 43, and a pressure spring 72 is connected between the sliding block 71 and the limiting column 43, and one side of the two sliding blocks 71 is fixedly connected to a pressure plate 73, and one side of the two pressure plates 51 is fixedly connected to a pressure rod 730, and the pressure rod 730 contacts the upper part of the pressure plate 73, and one side of the two sliding blocks 71 is A magnetic rod 1 74 is fixedly connected, and a magnetic rod 2 75 is fixedly connected to the lower part of the two limit columns 43. A clamping plate 76 is fixedly connected to the two magnetic rods 2 75 and the two magnetic rods 1 74. A supporting side rod 77 is fixedly connected to one side of the two vertical plates 42. A swing rod 78 is rotatably connected to the two supporting side rods 77. A torsion spring 79 is connected between the swing rod 78 and the supporting side rod 77. An elliptical block 710 is fixedly connected to one end of the two swing rods 78 close to the clamping plate 76, and the elliptical block 710 is in contact with the clamping plate 76 at the lower part.

[0034] When the pressure plate 51 moves downward, it will drive the pressure rod 730 to move downward together. The downward movement of the pressure rod 730 will squeeze and drive the pressure plate 73 and the sliding block 71 to move downward together. The pressure spring 72 is compressed, and the downward movement of the sliding block 71 will drive the magnetic rod 1 74 to move downward. When the pressure plate 51 contacts and clamps the wiring harness, the magnetic rod 1 74 and the magnetic rod 2 75 contact and attract each other, and the pressure plate 73 also contacts the wiring harness, and then the two clamping plates 76 also clamp the elliptical block 710 in the middle. After the cutter 56 cuts the wiring harness, the cutter 56 and the pressure plate 51 reset upward. Since the magnetic rod 1 74 and the magnetic rod 2 75 attract each other, the sliding block 71 and the pressure plate 73 will not reset upward, so that the pressure plates 73 on both sides press the wiring harness. The cut wire harness will still be clamped on the supporting chassis 41, and then the operator can toggle the swing lever 78 on the side of the connector close to the wire harness by 90°. The torsion spring 79 is twisted, and the swing lever 78 rotates 90°, which will drive the elliptical block 710 to rotate 90° together. The elliptical block 710 rotates 90° to squeeze the upper and lower clamping plates 76, so that the upper clamping plate 76 is squeezed and moved upward for a distance, thereby separating the magnetic rod 1 74 and the magnetic rod 2 75 from each other, and then the pressure spring 72 drives the sliding block 71 and the pressure plate 73 to move upward and reset, releasing the cut wire harness connector, while the wire harness on the other side is still pressed and clamped by the pressure plate 73, which makes it convenient for the operator to connect the cut wire harness.
