[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-6 As shown, a wire rope length range detection fixture includes a mounting main board 1, an inlet block 2 mounted on the mounting main board 1, an adjustment structure 3 on the inlet block 2, and a guide sleeve 301 mounted on the inlet block 2. A connecting pipe 302 is fixedly connected to the guide sleeve 301, and multiple connecting posts 303 are slidably connected to the connecting pipe 302. A connecting plate 304 is fixedly connected to the connecting posts 303, and ball bearings 305 are rotatably connected to the connecting posts 303. A drive ring 306 is slidably connected to the guide sleeve 301, and the ball bearings 305 and the drive ring 306 are in rolling engagement.

[0025] As a technical optimization of this utility model, the driving ring 306 is fixed by a fixing structure 4. The fixing structure 4 includes an adjusting rod 401. The adjusting rod 401 is fixedly connected to the driving ring 306. The adjusting rod 401 is slidably connected to the guide sleeve 301. An adjusting block 402 is slidably connected to the guide sleeve 301. The adjusting rod 401 is slidably connected to the adjusting block 402. A limiting block 404 is slidably connected to the adjusting rod 401. The adjusting block 402 is provided with multiple limiting grooves 405. The limiting block 404 engages with one of the limiting grooves 405. The engagement of the limiting block 404 with the adjusting block 402 facilitates the fixing of the sliding adjusting rod 401, enhances stability, and facilitates quick adjustment. A connecting rod 406 is fixedly connected to the limiting block 404. The connecting rod 406 is slidably connected to the adjusting rod 401. A pressing block 408 is fixedly connected, and the pressing block 408 is slidably connected to the adjusting rod 401. A guide frame 403 is fixedly connected to the guide sleeve 301, and the adjusting block 402 is slidably connected to the guide frame 403. A first lead screw 409 is threadedly connected to the guide frame 403, and the adjusting block 402 is threadedly connected to the first lead screw 409. A guide shaft 410 is fixedly connected to the guide frame 403. When fine adjustment is required, the first lead screw 409 is rotated by a rotating block on the first lead screw 409. When the first lead screw 409 rotates, the adjusting block 402 is threadedly driven to slide on the guide frame 403. When the adjusting block 402 slides, it slides smoothly through the guide shaft 410, thereby driving the adjusting rod 401 to move, so as to achieve further fine adjustment. The adjusting block 402 is slidably connected to the guide shaft 410, and a first spring 407 is fixedly connected between the connecting rod 406 and the adjusting rod 401.

[0026] As a technical optimization of this utility model, the connecting plate 304 is guided by the guide structure 5, which includes a guide plate 501. The guide plate 501 is fixedly connected to the connecting plate 304. When the connecting plate 304 moves, it will drive the guide plate 501 to move. The guide plate 501 drives the mounting plate 502 to slide on the mounting ring 503, causing the second spring 504 to contract. The inclined design of the guide plate 501 can guide the flexible shaft. The mounting plate 502 is fixedly connected to the guide plate 501. The mounting ring 503 is fixedly connected to the guide sleeve 301. The second spring 504 is fixedly connected between the mounting plate 502 and the mounting ring 503.

[0027] As a technical optimization of this utility model, the guide block 2 is provided with a rolling structure 6, the rolling structure 6 includes a slide block 601, the slide block 2 is slidably connected to the slide block 2, the slide block 601 is rotatably connected to the rotating shaft 602, the rotating shaft 602 is fixedly connected to the guide wheel 603, the guide block 2 is rotatably connected to the second lead screw 604, the second lead screw 604 is rotatably connected to the slide block 601, the second lead screw 604 can be driven to rotate by the rotating block on the second lead screw 604, when the second lead screw 604 rotates, the slide block 601 is driven to move by the thread, thereby adjusting the position of the guide wheel 603, so as to guide the flexible shafts of different diameters. The mounting main board 1 is equipped with a mounting base 11, the mounting base 11 is equipped with a fixing base 7, the fixing base 7 is slidably connected to the top column 8, the top column 8 is threadedly connected to the bolt 9, and a third spring 10 is installed between the bolt 9 and the mounting base 11.

[0028] In use, when measuring the automotive flexible shaft, the flexible shaft is first guided by the guide wheel 603, and multiple connecting plates 304 also assist in the guidance. When the end of the automotive flexible shaft abuts the bolt 9, the top column 8 moves accordingly. At the same time, the third spring 10 contracts, and the top column 8 and the fixed seat 7 are displaced. The contact piece 12 (on / off type PNP contactor) installed on the top column 8 and the mounting hole at the end of the mounting seat 11 can be used to install a proximity sensor. The on / off type PNP contactor and the proximity sensor sense relevant signals and convert them into electrical signals, which are then transmitted to the control system. The product length data is calculated. If the length meets the preset specifications, the process begins. The injection molding machine sends a feedback signal to its control system, and then performs subsequent cutting and assembly processes. When the position of the connecting plate 304 needs to be adjusted according to different diameter automotive flexible shafts, pressing the pressing block 408 moves the connecting rod 406, causing the first spring 407 to contract. After the limiting block 404 is no longer engaged with the adjusting block 402, the adjusting rod 401 drives the drive ring 306 to slide on the connecting tube 302, and the ball bearing 305 rolls on the drive ring 306, thereby driving the connecting column 303 to slide on the connecting tube 302, thus adjusting the position of the connecting plate 304 to adapt to flexible shafts of different diameters and improve flexibility. Ring 306 can simultaneously drive multiple connecting plates 304 to move, eliminating the need to replace guide sleeve 301 and guiding automotive flexible shafts of different diameters, thus improving practicality. When the connecting plate 304 moves, it drives the guide plate 501 to move. The guide plate 501 causes the mounting plate 502 to slide on the mounting ring 503, causing the second spring 504 to contract. The inclined design of the guide plate 501 guides the flexible shaft. After moving to a certain position, releasing the pressing block 408 allows the limiting block 404 to engage with the limiting groove 405 under the action of the first spring 407. The limiting block 404 then engages with the adjusting block 402, facilitating the fixation of the slidable adjusting rod 401. To enhance stability and facilitate quick adjustment, when fine adjustment is required, the first lead screw 409 is rotated by a rotating block on the first lead screw 409. When the first lead screw 409 rotates, the threaded adjustment block 402 slides on the guide frame 403. When the adjustment block 402 slides, it slides smoothly through the guide shaft 410, thereby driving the adjustment rod 401 to move, achieving further fine adjustment. At the same time, the second lead screw 604 can be rotated by a rotating block on the second lead screw 604. When the second lead screw 604 rotates, the threaded slide block 601 moves, thereby adjusting the position of the guide wheel 603 to guide automotive flexible shafts of different diameters.
