[0020] The utility model will now be further described with reference to the accompanying drawings and specific embodiments:

[0021] Please see Figure 1-4 A cutting device for automotive wiring harness production according to an embodiment of the present invention includes a reciprocating mechanism 1 and an adjusting mechanism 2. The bottom of the reciprocating mechanism 1 is vertically mounted on a base 3, and the adjusting mechanism 2 is mounted at both ends of the base 3. In actual use, the reciprocating mechanism 1 can swing back and forth to cut different wiring harnesses. The adjusting mechanisms 2 at both ends of the base 3 ensure the stability of the wiring harness during cutting. The base 3 supports the reciprocating mechanism 1, maintaining its stability.

[0022] In this embodiment, the reciprocating mechanism 1 includes a vertical plate 101, a turntable 102, a swing frame 104, and a shearing rod 105. In this embodiment, in order to save materials, the vertical plate 101 has an inverted T structure. In other embodiments not shown, the vertical plate 101 can also have any structure. A drive motor 103 is installed on one side of the vertical plate 101. The turntable 102 is installed on the other side of the vertical plate 101. A drive shaft 1022 is connected between the turntable 102 and the drive motor 103. The drive shaft 1022 connects the turntable 102 and the shaft of the drive motor 103. A guide post 1021 is installed at an eccentric position on one side of the turntable 102. The length of the inner hole of the swing frame 104 is greater than the diameter of the turntable 102. The guide post 1021 is slidably disposed in the swing frame 104. An installation shaft 1023 is installed on the vertical plate 101. The installation shaft 1023 is disposed below the turntable 102. When the guide post 1021 rotates with the turntable 102, it drives the swing frame 104 to swing around the installation shaft 1023. A gear 1041 is connected to the bottom of the swing frame 104. The gear 1041 and the swing frame 104 are rotatably disposed between the installation shaft 1023.

[0023] Guide sleeves 107 are installed at both ends of the vertical plate 101. A shearing rod 105 is also installed on the vertical plate 101, positioned below the mounting shaft 1023. Both ends of the shearing rod 105 are slidably connected to the guide sleeves 107. A rack 106 is provided on the side of the shearing rod 105 closest to the mounting shaft 1023, meshing with a gear 1041. Extension rods 110 are also provided at both ends of the shearing rod 105, with shearing plates 108 mounted on the extension rods 110. A slice 109 is installed on one side of the plate 8. When the guide post 1021 rotates around the drive shaft 1022 with the turntable 102, the guide post 1021 will also drive the swing frame 104 to swing around the mounting shaft 1023. While the swing frame 104 swings, it will also drive the gear 1041 to rotate synchronously around the mounting shaft 1023. While the gear 1041 rotates, it will drive the shearing rod 105 to slide in the guide sleeve 107 through the rack 106. Finally, the slice 109 on the shearing plate 108 is used for reciprocating shearing.

[0024] There are two adjustment mechanisms 2, symmetrically arranged about the drive shaft 1022. Each adjustment mechanism 2 includes a fixed housing 201, a support frame 206, and a lead screw 207. The fixed housing 201 has a second square hole 213 and a first square hole 212. The second square hole 213 facilitates the insertion of the slice 109, thereby enabling the cutting of the wire harness. A guide wheel 202 is installed at the bottom of the inner wall of the fixed housing 201, which supports the wire harness and keeps it stable. A push plate 203 is movably installed inside the fixed housing 201. A bearing 204 is installed on one side of the push plate 203, and a guide rod 205 is provided above the bearing 204. The guide rod 205 is connected to the push plate 203. A guide hole 210 is provided above the first square hole 212. The guide rod 205 passes through the guide hole 210, which limits the push plate 203 and prevents the wire harness from becoming loose during the cutting process.

[0025] The support frame 206 is installed on the outer wall of the first square hole 212. A circular hole 211 is opened on one side of the support frame 206. The circular hole 211 is horizontally aligned with the bearing 204. The lead screw 207 passes through the circular hole 211 and is connected to the bearing 204. The lead screw 207 is rotatably connected to the push plate 203 through the bearing 204. A threaded sleeve 208 is installed in the circular hole 211. The lead screw 207 is adjusted by the threaded sleeve 208. A rotating handle 209 is connected to one end of the lead screw 207. Rotating the rotating handle 209... The rotating handle 209 drives the lead screw 207 to rotate. While rotating, the lead screw 207 moves and adjusts within the threaded sleeve 208 through its external threads. Since the threaded sleeve 208 is fixedly installed in the round hole 211 on the support frame 206, the threaded sleeve 208 will not move or rotate. While the lead screw 207 moves, it drives the push plate 203 to advance through the bearing 204. When the push plate 204 abuts against the wire harness, it can ensure that the wire harness is in a relatively stable state when it is cut by the slicer 109.

[0026] The turntable 102 is driven to rotate by the drive motor 103, eliminating the need for manual cutting. The turntable 102 drives the swing frame 104 to swing. The gear 1041 connected to the swing frame 104 is connected by the mounting shaft 1023. The swing frame 104 drives the gear 1041, which meshes with the rack 106. The rack 106 drives the shearing rod 105 to reciprocate. When the shearing rod 105 drives the shearing plate 108 to reciprocate, the shearing plate 108 will drive the slice 109 to extend into the second square hole 213 of the fixed housing 201. The push plate 203 is adjusted by the lead screw 207. The guide rod 205 fixes the push plate 203 to prevent the lead screw 207 from rotating the push plate 203 during adjustment. The push plate 203 keeps the wire harness stable during cutting. When the shearing rod 105 slides to one end, the slice 109 at that end will approach the wire harness and perform a cut, while the slice 109 at the other end of the shearing rod 105 will move away from the wire harness. When the slice 109 that has completed the cut begins to reset, the slice 109 that is away from the wire harness will begin to approach the wire harness for a second cut. In this way, two cuts can be performed when the shearing rod 105 makes one reciprocating adjustment, which increases the cutting efficiency.

[0027] In use, the drive motor 103 is started first. The drive motor 103 drives the turntable 102 through the drive shaft 1022. The turntable 102 drives the guide post 1021 to rotate. The guide post 1021 drives the swing frame 104 to move together. Since the gear 1041 and the swing frame 104 are connected by the mounting shaft 1023, when the swing frame 104 rotates, the gear 1041 will reciprocate. The gear 1041 drives the rack 106, and the rack 106 drives the shearing rod 105, which uses the slices 109 on the shearing plate 108 to perform reciprocating shearing.

[0028] Secondly, adjustments are made according to the number of wire harnesses. When the wire harness passes through the guide wheel 202 and through the fixed housing 201, the rotating handle 209 is rotated. The rotating handle 209 drives the lead screw 207, which in turn drives the push plate 203 installed in the fixed housing 201 to advance. When pushed to the appropriate position, the lead screw 207 is fixed by the screw sleeve 208. Finally, the shearing rod 105 extends into the second square hole 213 of the fixed housing 201, and the slice 109 contacts the wire harness to cut it. After cutting, the swing frame 104 drives the gear 1041 to swing in another direction. At this time, the slice 109 at the other end of the shearing rod 105 contacts the wire harness to cut it, thus achieving a reciprocating cutting effect.
