Description

Technical Field

[0001] This invention relates to the field of wire harness cutting technology, and more specifically, to an automotive wire harness cutting device. Background Technology

[0002] Automotive wire harness cutting equipment is a key piece of equipment in the automotive manufacturing and wire harness processing industry. It is mainly used to precisely and efficiently cut various wire harness materials to meet the assembly requirements of automotive electrical systems.

[0003] The main types of cutting equipment are as follows: fully automatic tube cutting machines, which can automatically complete the cutting of wire harnesses. These machines are usually equipped with advanced control systems and cutting mechanisms to adapt to the cutting needs of wire harnesses of different specifications and materials; laser cutting equipment, which features high speed, high precision, and high stability, and produces smooth cutting edges without the need for post-processing, making it particularly suitable for applications requiring high cutting precision; and mechanical automatic cutting equipment, which uses mechanical structures to cut wire harnesses. It features simple structure, convenient operation, and low cost, and is widely used in automotive wire harness processing production lines.

[0004] The mechanical automatic wire harness cutting machines commonly used in the market generally have a wire feeding mechanism and a cutting mechanism. The cutting mechanism can not only cut the automotive wire harness, but also use different cutting blades to cut the outer and inner protective layers of the wire harness end, thereby stripping the wire harness end and exposing the wire core inside, which is convenient for subsequent connection of the wire core to other components. The wire core commonly used is copper wire made of copper material. Copper wire has good conductivity, and cutting automotive wire harnesses is also a process of processing and manufacturing copper material.

[0005] Currently, existing wire harness cutting machines, when cutting and stripping automotive wire harnesses, require the cutting blade to first cut the outer protective layer of the wire harness after the wire harness is cut, then move the cutting blade backward to remove the outer protective layer, and finally return the cutting blade to cut and remove the inner protective layer of the wire harness. However, the repeated movement of the cutting blade wastes time, and it can only cut and strip one end of the wire harness at a time, which easily affects the efficiency of automotive wire harness cutting. Therefore, it does not meet the current needs, and we propose an automotive wire harness cutting device. Summary of the Invention

[0006] This invention provides an automotive wiring harness cutting device that can simultaneously cut and strip the insulation from both ends of the wiring harness, thereby improving the efficiency of automotive wiring harness cutting. It solves the problem mentioned in the background art: when existing wiring harness cutting machines cut and strip the insulation from automotive wiring harnesses, after the wiring harness is cut, the cutting blade needs to first cut open the outer protective layer of the wiring harness, then move backward to remove the outer protective layer, and then return to its original position to cut and remove the inner protective layer. However, this repeated movement of the cutting blade wastes time, and only one end of the wiring harness can be cut and stripped at a time, which easily affects the efficiency of automotive wiring harness cutting.

[0043] According to some embodiments of this disclosure, an automotive wiring harness cutting device is provided, with reference to... Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 11 , Figure 12 and Figure 13As shown, the automotive wiring harness cutting equipment includes a wiring harness body 100 awaiting cutting and stripping, a cutting machine 110, a wire feeding mechanism 120 disposed on the side of the cutting machine 110, and a wire conduit 130. A winding reel 140 is movably disposed on the outside of the cutting machine 110, allowing the winding reel 140 to rotate while translating. A fixing block 150 is fixedly installed on the outside of the cutting machine 110, sleeved in the middle of the wire conduit 130. A cutting blade 160 is slidably disposed on the inner side of the fixing block 150, and the cutting blade 160 is used to cut the wiring harness body 100. The winding reel 140... A wire pressing plate 170 is movably disposed on the side of the cutting machine 110. An extension plate 180 is slidably inserted into the end of the wire pressing plate 170. A movable block 190 is movably disposed on the side of the cutting machine 110. A first wire stripper 200 is installed on the side of both the movable block 190 and the extension plate 180.

[0048] The first wire stripper 200 is an arc-shaped blade used in conjunction with the outer protective layer 101. The number of the first wire stripper 200 is set to four, with two first wire stripper 200 respectively set in the two wire placement grooves 182 on the extension plate 180, and the other two first wire stripper 200 fixedly installed on the outside of the movable block 190.

The lower end of the threaded sleeve 197 is slidably inserted into the lower side of the connecting frame 194, and the lower end of the threaded sleeve 197 is fixedly connected to the movable block 190.

[0050] A second electric push rod 201 is fixedly installed inside the cutting machine 110. A sleeve rod 202 is fixedly installed at the telescopic end of the second electric push rod 201. A slide rod 203 is slidably inserted into the end of the sleeve rod 202. A third slide groove 204 is opened on the side wall of the cutting machine 110. The end of the slide rod 203 passes through the third slide groove 204 and is fixedly connected to the connecting frame 194. A limiting ball 205 is interference-fitted in the middle of the slide rod 203. A fourth slide groove 206 is opened on the side wall of the cutting machine 110 to cooperate with the limiting ball 205. The limiting ball 205 is slidably disposed in the fourth slide groove 206. The fourth slide groove 206 includes a straight groove 2061 and a curved groove 2062. The straight groove 2061 is a vertical groove. The curved groove 2062 is connected to the lower end of the straight groove 2061 and is an "S" shaped groove.

[0051] The drive assembly 210 includes a first wedge block 211 slidably disposed inside the fixed block 150 and fixedly connected to the cutting blade 160, a second wedge block 212 slidably disposed inside the fixed block 150 and used in conjunction with the first wedge block 211, a second spring 213 fixedly connected to the outside of the second wedge block 212, a second connecting rod 214 fixedly connected to the outside of the second wedge block 212, a third wedge block 215 fixedly installed at the end of the second connecting rod 214, and a fourth wedge block 216 fixedly installed outside the movable block 190 and used in conjunction with the third wedge block 215. The second spring 213 is disposed inside the fixed block 150, and its two ends are fixedly connected to the second wedge block 212 and the inner wall of the fixed block 150, respectively. The second connecting rod 214 is slidably inserted into the side of the fixed block 150, and the second spring 213 is sleeved on the outside of the second connecting rod 214.

[0052] A third spring 221 is provided on the inner side of the movable block 190. The positioning plate 220 is slidably inserted into the lower side of the movable block 190. The two ends of the third spring 221 are fixedly connected to the inner wall of the movable block 190 and the positioning plate 220 respectively. The positioning plate 220 is used to press the inner protective layer 102 of the wire harness body 100 onto the extension plate 180.

[0053] Through the above technical solution, the automotive wire harness cutting equipment provided in this disclosure, when in use, uses the wire feeding mechanism 120 and the wire tube 130 to transport the wire harness body 100. When the end of the wire harness body 100 rests on the upper side of the winding reel 140, the telescopic end of the first electric push rod 191 drives the pressure plate 170 and the extension plate 180 to press down on the end of the wire harness body 100 through the first connecting rod 193. Subsequently, the output shaft of one end of the dual-head motor 141 drives the winding reel 140 to rotate. At the same time, the output shaft of the other end of the dual-head motor 141 drives the gear 143 to rotate. Through the meshing of the gear 143 and the rack 144, the gear 143 drives the dual-head motor 141 and the winding reel 140 to translate, so that the winding reel 140 rotates and translates at the same time, so that the wire harness body 100 is wound on the winding reel 140.

[0054] When the reel 140 rotates 180 degrees, the pressure plate 170 flips along with the rotation of the reel 140, so that the end of the wire harness body 100 is simultaneously located on the upper side of the pressure plate 170 and the extension plate 180. The second electric actuator 201, through the cooperation of the sleeve rod 202 and the slide rod 203, drives the connecting frame 194 and the movable block 190 to move downward. The slide rod 203 drives the limiting ball 205 to slide within the straight groove 2061. During the downward movement of the movable block 190, the movable block 190 drives the fourth wedge block 216 to move downward and meet the first When the three wedge blocks 215 come into contact, the third wedge block 215 is squeezed to the left, so that the third wedge block 215 pushes the second wedge block 212 to the left through the second connecting rod 214. The leftward movement of the second wedge block 212 causes the second spring 213 to be stretched. Through the cooperation of the second wedge block 212 and the first wedge block 211, the first wedge block 211 drives the cutting blade 160 to press down and cut the wire harness body 100. Immediately afterwards, the wire feeding mechanism 120 stops operating, thereby stopping the feeding of the wire harness body 100.

[0055] Subsequently, the second electric actuator 201 drives the movable block 190 of the slide rod 203 to continue moving downwards, and the moving movable block 190 also presses the other end of the cut wire harness body 100 onto the extension plate 180, so that both ends of the wire harness body 100 fall on the extension plate 180 and are basically aligned. In addition, when the movable block 190 approaches the extension plate 180, the slide rod 203 drives the limiting ball 205 to slide within the curved groove 2062. Through the sliding cooperation between the limiting ball 205 and the curved groove 2062, the slide rod 203 drives the connecting frame 194 and the movable block 190 to move slightly in the front-back direction, thereby rubbing the two ends of the wire harness body 100 back and forth, so that the two ends of the wire harness body 100 are respectively located in the two wire placement grooves 182 on the extension plate 180. Inside, the movable block 190 drives the two first wire strippers 200 to press down on both ends of the wire harness body 100, thereby cutting off the outer protective layer 101. Then, the drive motor 196 drives the lead screw 195 to rotate. Through the cooperation of the lead screw 195 and the wire sleeve 197, the wire sleeve 197 drives the movable block 190 and the first wire stripper 200 to move to the left. At the same time, the friction between the outer protective layer 101 and the extension plate 180 also causes the outer protective layer 101 to drive the extension plate 180 to move synchronously, and the first spring 181 is stretched, so that the first wire stripper 200 completely breaks the outer protective layer 101 at both ends of the wire harness body 100 and removes the outer protective layer 101 from several inner protective layers 102, thereby exposing the inner protective layers 102 at both ends of the wire harness body 100.

[0056] Furthermore, the movable block 190 continues to move to the left, and the positioning plate 220 lays and presses several inner protective layers 102 flat onto the extension plate 180. Subsequently, the second wire stripper 230 in the extension plate 180 and the second wire stripper 230 in the movable block 190 approach each other and cut the upper and lower sides of the inner protective layer 102. As the movable block 190 drives the second wire stripper 230 to move to the left, the second wire stripper 230 completely breaks the inner protective layer 102 and peels it off from the wire core 103, thereby exposing the wire core 103 at both ends of the wire harness body 100. This achieves simultaneous cutting and stripping of both ends of the wire harness body 100. Finally, the pressure plate 170 and the movable block 190 reset, releasing the pressure on the wire harness body 100. During the reset of the winding reel 140, the wire harness body 100 wound on the winding reel 140 falls off the winding reel 140, completing the unloading of the wire harness body 100.

[0057] In summary, the wire harness body 100 is cut to a fixed length by the cutting blade 160, and the wire harness body 100 is wound onto the winding reel 140 by its rotation and translation. With the cooperation of the extension plate 180 and the movable block 190, the two ends of the wire harness body 100 are pressed. The outer protective layer 101 and the inner protective layer 102 at both ends of the wire harness body 100 can be stripped in one leftward stroke of the movable block 190, thereby effectively improving the work efficiency of cutting and stripping the wire harness body 100.

[0058] It should be noted that when the movable block 190 drives the fourth wedge block 216 to reset, the inclined surface on the upper side of the fourth wedge block 216 slides and engages with the inclined surface on the lower side of the third wedge block 215, pushing the third wedge block 215 to the left. This avoids the third wedge block 215 obstructing the reset of the movable block 190. During the reset process of the movable block 190, the wire feeding mechanism 120 stops feeding the wire harness body 100, so that the downward-pressing cutting blade 160 will not cut the wire harness body 100. The conveyor belts 122 of the two wire feeding mechanisms 120 can move closer or further apart from each other, which facilitates clamping or releasing the wire harness body 100. It also facilitates adjusting the distance between the two conveyor belts 122 according to the diameter of different wire harness bodies 100, so that the wire feeding mechanism 120 is suitable for automotive wire harnesses of different diameters. The wire feeding mechanism 120 and the dual-head motor 141 are technical means well known to those skilled in the art and will not be described in detail here.

[0059] In some embodiments of this disclosure, reference is made to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 10 , Figure 11 , Figure 12 and Figure 13 As shown, a fourth spring 231 is provided on the inner side of both the movable block 190 and the extension plate 180. The two ends of the fourth spring 231 in the movable block 190 are fixedly connected to the second wire stripper 230 and the inner wall of the movable block 190, respectively. The two ends of the fourth spring 231 in the extension plate 180 are fixedly connected to the second wire stripper 230 and the inner wall of the extension plate 180, respectively.

[0060] A first lever 240 is rotatably inserted into the side wall of the extension plate 180. A first rotating shaft 241 is fixedly connected to the middle of the first lever 240. The end of the first rotating shaft 241 is rotatably inserted into the side wall of the extension plate 180. One end of the first lever 240 is rotatably connected to a second wire stripper 230 located inside the extension plate 180. A fifth wedge block 242 is fixedly installed at the other end of the first lever 240. Similarly, a second lever 243 is rotatably inserted into the side wall of the movable block 190. A second rotating shaft 244 is fixedly connected to the middle of the second lever 243. The end of the second rotating shaft 244 is rotatably inserted into the movable block 190. Inside the side wall of 0, one end of the second lever 243 is rotatably connected to the second wire stripper 230 located inside the movable block 190, and the other end of the second lever 243 is fixedly installed with the sixth wedge block 245. The outer side of the movable block 190 is fixedly connected with the mounting plate 246, and the outer side of the mounting plate 246 is fixedly installed with the third electric push rod 247. The telescopic end of the third electric push rod 247 is fixedly installed with the seventh wedge block 248. The lower inclined surface of the seventh wedge block 248 is in sliding engagement with the inclined surface of the fifth wedge block 242, and the upper inclined surface of the seventh wedge block 248 is in sliding engagement with the inclined surface of the sixth wedge block 245.

[0061] The second wire stripper 230 has different states at different times.

[0062] For example, in some embodiments, reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 11 , Figure 12 and Figure 13 As shown, the second wire stripper 230 can have a first state, which is when it is not in use. In the first state, the seventh wedge block 248 is separated from the fifth wedge block 242 and the sixth wedge block 245, so that one second wire stripper 230 is stationary inside the extension plate 180 and the other second wire stripper 230 is stationary inside the movable block 190.

[0063] For example, in some embodiments, reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 11 , Figure 12 and Figure 13 As shown, the second wire stripper 230 can have a second state, which is when in use. In the second state, the second wire stripper 230 located in the extension plate 180 moves upward, while the second wire stripper 230 located in the movable block 190 moves downward to strip the inner protective layer 102 of the wire harness body 100.

[0064] The second wire stripper 230 will now be described in detail with reference to the specific embodiments described above. (See also...) Figure 3 , Figure 4 , Figure 11 , Figure 12 and Figure 13 As shown, when the movable block 190 drives the first wire stripper 200 to strip the outer protective layer 101 at both ends of the wire harness body 100, several inner protective layers 102 that wrap the wire core 103 can be exposed. Through the downward pressure of the positioning plate 220, not only can the stacked inner protective layers 102 be pressed down and flattened, but also several inner protective layers 102 can be pressed tightly onto the extension plate 180 to position the inner protective layers 102.

[0065] The movable block 190 continues to drive the third electric push rod 247 and the seventh wedge block 248 to move. Subsequently, the telescopic end of the third electric push rod 247 drives the seventh wedge block 248 to move, causing the lower side of the seventh wedge block 248 to abut against the fifth wedge block 242, causing the first lever 240 to rotate. This causes the first lever 240 to drive the second wire stripper 230 inside the extension plate 180 to move upward and slide out of the extension plate 180. At the same time, the upper side of the seventh wedge block 248 abuts against the sixth wedge block 245, causing the second lever 243 to rotate. This causes the second lever 243 to drive the second wire stripper 230 inside the movable block 190 to move downward and slide out of the movable block 190. When the second wire stripper 230 moves, it causes the fourth spring 231 to be stretched. At this time, several inner protective layers 102 are flattened and pressed between the extension plate 180 and the movable block 190. By the mutual approach of the two second wire strippers 230, the upper and lower sides of the inner protective layer 102 are cut open.

[0066] Finally, the movable block 190 moves again, completely breaking the inner protective layer 102 and removing it, thereby exposing the wire core 103 wrapped inside, completing the simultaneous cutting and stripping of both ends of the wire harness body 100. When the telescopic end of the third electric push rod 247 drives the seventh wedge block 248 to move backward and reset, the second wire stripper 230 can be reset under the action of the rebound force of the fourth spring 231.
