Detailed Implementation

[0018] like Figures 1 to 12 As shown, a novel automatic sleeve cutting device in this embodiment includes a support 1, on which a guide groove 2 is provided. The guide groove 2 is used to support and guide the sleeve during conveying. A sleeve feeding mechanism 3, a sleeve cutting mechanism 4, and a length fixing mechanism 5 are sequentially arranged on the support 1 along the sleeve conveying direction. The sleeve feeding mechanism 3 and the sleeve cutting mechanism 4 are both located on one side of the guide groove 2. The sleeve feeding mechanism 3 is used to convey the sleeve to the sleeve cutting mechanism 4. The sleeve cutting mechanism 4 is used to perform the sleeve cutting action. The length fixing mechanism 5 is used to determine the cutting length of the sleeve. The tube feeding mechanism 3 includes a tube feeding seat 31, which is fixedly connected to the bracket 1. Two tube feeding assemblies 32 are provided on the tube feeding seat 31, and the two tube feeding assemblies 32 are symmetrically distributed vertically. The tube feeding assembly 32 includes two rotating wheels 321, which are distributed along the tube feeding direction. The two rotating wheels 321 are connected by a synchronous belt 322, and one of the rotating wheels 321 is driven by a first motor 323. A gap is provided between the two synchronous belts 322; During the casing conveying process, the casing is placed between two synchronous belts 322, and the casing is distributed against the two synchronous belts 322. When the first motor 323 starts, the rotating wheel 321 drives the synchronous belts 322 to rotate, and the two synchronous belts 322 rotate in opposite directions. Moreover, when the synchronous belts 322 rotate, they drive the casing to move through friction, thus realizing the conveying of the casing. The pipe cutting mechanism 4 includes a pipe cutting support 41, a moving plate 42, and a cover 43. The pipe cutting support 41 is fixedly connected to the bracket 1. The moving plate 42 is slidably connected to the pipe cutting support 41. The cover 43 is located on one side of the moving plate 42. A grinding wheel 44 is disposed inside the cover 43. A driving system is disposed on the moving plate 42. The driving system is connected to the grinding wheel 44 in a transmission manner. A guide tube 46 is inserted into one side of the cover 43. The guide tube 46 is fixedly connected to the pipe cutting support 41. A first sensor 47 is fixedly disposed on the guide tube 46. The first sensor 47 is used to detect the grinding wheel 44. A moving component 48 is disposed on the pipe cutting support 41. The moving component 48 is used to drive the moving plate 42 to move. The moving component 48 includes a lead screw 481, which is driven by a second motor 482. A slider 483 is connected to the lead screw 481 and is connected to the moving plate 42. A slide rail 484 is fixedly installed on the pipe cutting support 41. A sliding seat 485 is slidably connected to the slide rail 484 and is fixedly installed on the moving plate 42. The slide rail 484 is parallel to the lead screw 481. The moving component 48 also includes a cutting cylinder 486, which is used to drive the moving plate 42 to move. The cylinder body of the cutting cylinder 486 is fixedly mounted on the moving plate 42, and the piston end of the cutting cylinder 486 is connected to the slider 483. The pipe cutting mechanism 4 also includes a clamping assembly 49, which includes a clamping block 491 and a fixing block 492. The fixing block 492 is fixedly connected to the cover 43. A first cylinder 493 is connected to the clamping block 491, and a clamping groove 494 is provided on the clamping block 491. The sleeve delivered by the tube feeding mechanism 3 first passes through the guide tube 46, and after the sleeve is discharged from the guide tube 46, it passes through the cover 43. The sleeve located in the cover 43 passes between the clamping block 491 and the fixing block 492. In addition, the sleeve discharged from the cover 43 is supported and guided by the guide groove 2. After the length-fixing mechanism 5 determines the cutting length of the sleeve, the tube feeding mechanism 3 stops feeding the tube. Then, the clamping block 491 is driven to move by the first cylinder 493, and the clamping block 491 and the fixing block 492 clamp and fix the sleeve. At this time, the sleeve is inserted into the clamping groove 494. Next, the grinding wheel 44 is rotated by the drive system. At the same time, the moving plate 42 is moved by the cutting cylinder 486. The movement of the moving plate 42 causes the sliding seat 485 to move on the slide rail 484. The movement of the moving plate 42 also causes the drive system and the grinding wheel 44 to move synchronously, so that the grinding wheel 44 contacts the sleeve and cuts the sleeve. After the cut sleeve is taken out from the guide groove 2, the next sleeve can be cut. After long-term operation, the diameter of the grinding wheel 44 decreases due to wear. The diameter of the grinding wheel 44 is detected by the first sensor 47. Only when the first sensor 47 detects the grinding wheel 44 will the second motor 482 rotate the lead screw 481. The rotation of the lead screw 481 drives the slider 483 to move. The movement of the slider 483 drives the moving plate 42 to move synchronously a set distance through the cutting cylinder 486 and then stops. This ensures that the grinding wheel 44 can cut the sleeve, thus realizing the diameter compensation of the grinding wheel 44 and improving the reliability of sleeve cutting. The length-fixing mechanism 5 includes a length-fixing base 51, which is detachably and fixedly connected to the bracket 1. A second sensor 52 and a length-fixing plate 53 are provided on the length-fixing base 51. The length-fixing plate 53 is an L-shaped torsion spring. The length-fixing plate 53 is located on the side of the second sensor 52 near the tube cutting mechanism 4. The length-fixing plate 53 is rotatably connected to the length-fixing base 51. During the sleeve transport, the end of the sleeve abuts against the length plate 53. As the sleeve moves, it pushes the length plate 53 and causes the length plate 53 to rotate relative to the length seat 51, which in turn causes the torsion spring to deform. When the second sensor 52 detects a signal as the length plate 53 rotates, the sleeve transport stops, thus determining the sleeve cutting length. After the sleeve is cut and removed from the guide groove 2, the fixed length plate 53 rotates in the opposite direction and resets through the elastic action of the torsion spring. At this time, the second sensor 52 cannot detect the signal. In addition, when it is necessary to adjust the cutting length, simply adjust the position of the length-fixing seat 51 on the bracket 1. The guide groove 2 includes an optical axis 21 and a groove seat 22 distributed vertically. There are two optical axes 21, which are distributed horizontally at intervals. The distribution direction of the two optical axes 21 is perpendicular to the axial direction of the optical axis 21. The optical axis 21 is fixedly connected to the bracket 1. The length plate 53 is inserted between the two optical axes 21. After the sleeve passes through the cover 43, the bottom of the sleeve abuts against the top of the slot seat 22 to support the sleeve, and the two optical axes 21 abut against the two sides of the sleeve respectively to guide the sleeve during transportation. The guide groove 2 is connected to a feeding mechanism 6, which includes a push frame 61. The push frame 61 is fixedly connected to the groove seat 22. A second cylinder 62 is connected to the push frame 61, and the cylinder body of the second cylinder 62 is connected to the bracket 1. When the sleeve needs to be cut off and removed, the second cylinder 62 drives the pusher 61 to move. The movement of the pusher 61 drives the slot seat 22 to move synchronously. When the slot seat 22 moves to one side of the optical axis 21, the slot seat 22 stops supporting the sleeve and causes the sleeve to fall, thus realizing the unloading of the sleeve. Of course, a storage device can be placed at the position where the sleeve falls to realize the storage of the sleeve. After the sleeve is finished being cut, the second cylinder 62 drives the slot seat 22 to move in the opposite direction to achieve reset. The feeding mechanism 6 also includes a support plate 63, which is fixedly mounted on the slot seat 22. Rollers 64 are provided above and below the support plate 63. The rollers 64 are fixedly mounted on the bracket 1. The wheel surface of the rollers 64 abuts against the support plate 63. During the movement of the slot seat 22, the support plate 63 is driven to move on the rollers 64. Through the cooperation between the rollers 64 and the support plate 63, the slot seat 22 is supported and the slot seat 22 is limited in the vertical direction. The following table was obtained by collecting sleeve cutting data before and after the improvement; Table 1: Sleeve Cutting Data Before and After Improvement

[0019] According to the data in Table 1, the cutting accuracy is significantly improved after the improvement, and the accuracy requirement of ±0.5mm is met. In summary, by determining the cutting length of the sleeve, the cutting accuracy of the sleeve is improved. Furthermore, by moving the groove seat 22, the automatic feeding of the sleeve is achieved. In addition, by detecting the diameter of the grinding wheel 44 and controlling the moving distance of the grinding wheel 44, the diameter compensation of the grinding wheel 44 is realized, thereby improving the reliability of sleeve cutting.
