With this structure, the operator can insert the automobile wiring harness that needs to be trimmed into the trimming ring 8 and make the two ends pass through the sleeve 9 and place it on the outside of the side frame 2, and then use the cable ring 10 to limit the two ends of the automobile wiring harness. The movable block 11 can be displaced laterally outward through the cable ring 10 to straighten the automobile wiring harness as a whole. When the linear guide 4 drives the guide block 5 to move laterally, the corresponding trimming ring 8 can be used to move along the outside of the automobile wiring harness. The trimming ring 8 can achieve the effect of fast and automatic trimming of the automobile wiring harness. The equipment structure for trimming the automobile wiring harness is simpler, and the operation process is more time-saving and labor-saving. It solves the problem that the existing manual or semi-automatic equipment is time-consuming and labor-intensive to perform trimming, greatly shortens the production cycle, and the equipment can be used in a variety of production processes. It can be effectively applied in production environment without the need to use large-scale trimming machinery and equipment, and plays an important role in improving the efficiency and product quality of the automobile wiring harness injection molding production process. The inner wall of one of the trimming rings 8 is a brush structure, and the inner wall of the other trimming ring 8 is a scraper structure. The scraper is an annular structure and is connected to the inner wall of the trimming ring 8 by welding. One of the trimming rings 8 of this structure can cut the plastic overflow corners generated after the automobile wiring harness is demoulded through the scraper structure, and the other trimming ring 8 can grind the automobile wiring harness through the brush structure, so as to more effectively trim the automobile wiring harness. A screw sleeve 12 is welded and fixed to the bottom of the movable block 11, and an adjusting stud 13 is inserted into the inside of the screw sleeve 12, and the adjusting stud 1 3 is connected to the outer wall of the side frame 2 through a bearing, and a horizontally distributed limiting shaft 14 is provided at the connection between the side frame 2 and the movable block 11. The connection between the limiting shaft 14 and the side frame 2 is connected by welding, and a limiting hole matching the limiting shaft 14 structure is provided inside the movable block 11. When the adjusting stud 13 of this structure rotates on the outer side of the side frame 2, the screw sleeve 12 will be driven to move laterally outside the adjusting stud 13 through the threaded structure. The lateral movement of the screw sleeve 12 will synchronously generate linkage with the movable block 11. When the movable block 11 is linked, it can slide along the outer side of the limiting shaft 14 through the limiting hole to move laterally, so that the movable block 11 drives the cable ring 10 to adjust the position to straighten the automobile wiring harness. The upper and lower ends of the buckle 6 are symmetrically provided with connecting sleeves 15.A fixing pin 16 is inserted between the same group of the sleeves 15, and a through hole is provided inside the vertical shaft 7 that matches the structure of the fixing pin 16. The vertical shaft 7 of this structure can be fixed on the buckle 6 to switch the trimming ring 8 to be used, and the fixing pin 16 can be inserted into the through holes on the sleeves 15 and the vertical shaft 7 of the same group to quickly limit and fix the vertical shaft 7, thereby ensuring the stability of the trimming ring 8 when in use. The inner walls on both sides of the cable tie ring 10 are connected with a clamping piece 17 through an elastic block. The elastic block can be made of sponge material, and the bottom end of the cable tie ring 10 is welded and fixed with a screw The threaded column 18 is welded and fixed on the top of the movable block 11 with a threaded interface 19 that matches the threaded column 18 structure. When the cable ring 10 of this structure inserts the automobile wiring harness into it, it will squeeze the clamping piece 17. The clamping piece 17 can clamp the automobile wiring harness under the elastic force of the elastic pad to ensure the stability of the automobile wiring harness when limiting the position. The cable ring 10 can be rotated in the threaded interface 19 through the threaded column 18 to adjust the angle position, so as to drive the automobile wiring harness to twist to a certain extent, and further improve the stability of the automobile wiring harness when limiting the end.

[0019] Working principle: When using the trimming equipment for automobile wiring harness injection molding production, first, when it is necessary to trim the plastic overflow corners generated after the automobile wiring harness is demolded, first turn the trimming ring 8 with a scraper structure on the inner wall downward and fit the vertical shaft 7 into the inside of the buckle 6, and then insert the two fixed pins 16 into the through holes on the sleeve 15 and the vertical shaft 7 of the same group. After the position of the vertical shaft 7 is limited, the automobile wiring harness that needs to be trimmed is inserted into the trimming ring 8 and the two ends are passed through the sleeve 9 and placed on the outside of the side frame 2. At this time, the two ends of the automobile wiring harness are placed in the harness ring 10 to squeeze the clamping piece 17. The clamping piece 17 can clamp the automobile wiring harness under the elastic force of the elastic pad, and then the harness ring 10 rotates in the threaded interface 19 through the threaded column 18 to drive the automobile wiring harness. The car wiring harness is twisted to a certain extent, and at the same time, the adjusting stud 13 is rotated on the outside of the side frame 2. When the adjusting stud 13 is rotated, the movable block 11 can be driven to move laterally through the screw sleeve 12. When the movable block 11 moves laterally, it can slide along the outside of the limiting shaft 14 through the limiting hole. When the movable block 11 moves outward, it can drive the wiring ring 10 to adjust the position to straighten the automobile wiring harness. At this time, when the linear guide rail 4 drives the guide block 5 to move laterally, the guide block 5 can synchronously drive the trimming ring 8 to move along the outside of the automobile wiring harness. The trimming ring 8 automatically cuts and trims the automobile wiring harness through the internal scraper. When the automobile wiring harness needs to be polished and trimmed, the trimming ring 8 with a brush structure on the inner wall is adjusted to a vertical downward position in accordance with the above sequence, thereby completing a series of tasks.
