[0018] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0020] like Figures 1 to 3 As shown, the utility model discloses a shaft core fixed length cutting device for automobile flexible shaft processing, including a frame 1 and a straightening component 2, the frame 1 is rotatably connected with a connecting shaft 3 inside, the outer periphery of the connecting shaft 3 is used to set the shaft core reel 8, the frame 1 is provided with a traction component 4 inside, the traction component 4 includes a horizontally symmetrically arranged rotating shaft 41, the outer periphery of the rotating shaft 41 is fixedly set with a traction wheel 42, the traction wheel 42 is used to pull the shaft core on the shaft core reel 8 to the straightening component 2, and a cutting component 5 is provided between the straightening component 2 and the traction component 4, and the cutting component 5 is used to cut the shaft core sent out by the traction component 4 The cutting and straightening component 2 is used to send the traction component 4 to the shaft core of the cutting component 5 for straightening and traction. When the shaft core is cut, the shaft core can be transported to the cutting component 5 through the traction component 4. After the cutting component 5 cuts the shaft core, the remaining shaft core sent to the cutting component 5 can be pulled out through the straightening component 2, thereby achieving continuous traction and transportation of the shaft core. When the cutting component 5 cuts the shaft core, the shaft core can be straightened to ensure the cutting accuracy of the cutting component 5 on the shaft core, and then the soft shaft core can be automatically pulled to improve the continuity of the overall cutting of the soft shaft core.

[0021] In this embodiment, the specific structure of the cutting assembly 5 includes a driving shaft 51, which is rotatably connected to the inner side of the frame 1. A first motor 52 is provided on the outer periphery of the frame 1, and the first motor 52 is used to drive the driving shaft 51 to rotate. A driving disk 53 is fixedly mounted on the outer periphery of the driving shaft 51, and a mounting groove 531 is provided on the outer periphery of the driving disk 53. The mounting groove 531 is symmetrically provided with mounting seats 54, one end of the mounting seat 54 is rotatably connected to the mounting groove 531, and the other end serves as a connecting end, and a cutter head 55 is connected to the connecting end. A spring 56 is connected between adjacent mounting seats 54, and connecting seats 57 are provided on both sides of the driving disk 53. The connecting seats 57 are fixed to the inner side of the frame 1, and a connecting rod 58 extending upward is provided on the connecting seat 57. The end of the connecting rod 58 is rotatably connected to a driving wheel 59, and the connecting end is provided with a coupling side wall 541 formed by gradually offsetting inward along the rotation direction of the driving disk 53. The coupling side wall 541 contacts with the driving wheel 59 to The mounting seat 54 moves toward the passed shaft core. When the shaft core needs to be cut, the traction component 4 first sends the shaft core to the cutting component 5. After the shaft core is straightened by the straightening component 2, the driving shaft 51 is driven to rotate by the first motor 52, so that the driving disk 53 rotates along with the driving shaft 51. When the connecting end of the connecting rod 58 on the driving disk 53 contacts the driving wheel 59, due to the effect of the coupling side wall 541, the distance between the connecting end and the driving wheel 59 gradually decreases as the driving disk 53 rotates, so that the driving wheel 59 can push the mounting seat 54 to rotate toward the passed shaft core, so that the cutter heads 55 on the mounting seats 54 on both sides can move toward each other to achieve the cutting of the passed shaft core. In this way, the fixed-length cutting of the shaft core can be completed by the continuous rotation of the driving disk 53, and the cutting requirements of different lengths of the shaft core can be met by adjusting the rotation speed of the driving disk 53, thereby improving the convenience of use.

[0022] In this embodiment, the specific structure of the straightening component 2 includes a linear motor 21, a connecting arm 22 is fixed on the moving seat of the linear motor 21, and a pneumatic clamp 23 is fixed on the connecting arm 22. After the traction component 4 conveys the shaft core to the cutting component 5, the pneumatic clamp 23 is driven by the linear motor 21 to move toward the conveyed shaft core, and then the pneumatic clamp 23 clamps the shaft core, and then the pneumatic clamp 23 is driven by the linear motor 21 to move away from the cutting component 5. In this way, the shaft core can be continuously cut by reciprocating, and the shaft core can be kept in a taut state during cutting to ensure the cutting accuracy of the shaft core. The linear motor 21 and the pneumatic clamp 23 are both conventional technical means in the field of automation control technology, so their specific structure and principle are not repeated here.

[0023] In this embodiment, the end of the rotating shaft 41 extends outward as an extension end, and a transmission gear 43 is fixedly mounted on the outer periphery of the extension end. The transmission gears 43 on adjacent extension ends are meshed with each other. A second motor 44 is provided on the outer side of the frame 1. When the rotating shaft 41 is driven to rotate by the second motor 44, the mutually meshing transmission gears 43 can make the adjacent rotating shafts 41 rotate synchronously, so that the shaft core can be stably pulled and transported by the traction wheel 42 after passing through the adjacent traction wheel 42.

[0024] In this embodiment, a mounting plate 6 is further provided on the inner side of the frame 1, a discharge port 61 is provided on the mounting plate 6, the linear motor 21 is installed on the mounting plate 6, and a collection box 7 is provided below the discharge port 61. After the cutting assembly 5 cuts the shaft core once, the clamped shaft core is released by the pneumatic clamp 23, and the cut shaft core can fall into the collection box 7 below through the discharge port 61 under the action of gravity, so as to facilitate the collection of the cut shaft core.

[0025] In this embodiment, a positioning groove 532 is further provided on the outer periphery of the driving disk 53. The positioning groove 532 is connected to the mounting groove 531. The positioning groove 532 is for the shaft core to pass through. In this way, the shaft core can be positioned when the shaft core is cut to prevent the shaft core from being offset during the cutting process.

[0026] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
