Technical Field
[0001] This utility model relates to the field of code disk cutting technology, and in particular to a cutting fixture for a metal reflective code disk. Background Technology
[0002] A metal reflective code disk is a type of code disk made of metal, whose surface typically has reflective properties, reflecting light and forming specific optical signals. When light is projected onto the code disk surface, it is reflected and received by a photodetector, which then converts it into an electrical signal for processing. This type of code disk is usually combined with components such as a light source, a photodetector, and a slit to form an angle encoder or optical encoder, used to measure angles or displacements. The cutting fixture for the metal reflective code disk is one of the key tools to ensure its cutting accuracy and efficiency.
[0003] Existing metal reflective code disk cutting fixtures mainly include a base, a cutting base, and two cutting grooves. In use, the base is installed on a suitable location such as a machine tool, and the metal reflective code disk material is placed on the cutting base. The material is then cut along the cutting grooves to achieve the cutting process of the metal reflective code disk. However, in actual use, the metal material may become misaligned due to the cutting process, leading to cutting deviations. Furthermore, the edges of the cut code disk and scrap material have sharp burrs. Additionally, the metal reflective code disk is relatively thin, which combined with the fact that the code disk is difficult to remove from the cutting base after cutting, and that removing it can easily cause hand cuts.
[0004] Therefore, a cutting fixture for a metal reflective code disk is proposed to address the above problems. Utility Model Content

[0022] 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.
[0023] Specific implementation examples are given below.
[0024] Please see Figure 1 - Figure 5 This utility model provides a technical solution: a cutting fixture for a metal reflective code disk, including a base 1, a cutting base 2 fixedly installed at the top of the base 1, a cutting groove 3 and a cutting groove 4 opened at the top of the cutting base 2, an auxiliary structure 5 fixedly installed at the top of the cutting base 2, and a collecting structure 6 fixedly installed on one side of the cutting base 2. The auxiliary structure 5 includes a suction cup 51 fixedly connected to the middle of the top of the cutting base 2, and two suction cups 52 fixedly connected to the top of the base 1. Rubber rings 53 are fixedly connected to the outside of the suction cup 51 and the outside of the two suction cups 52. When the metal reflective code disk material is placed on the cutting base 2, the metal reflective code disk material is gently pressed, thereby causing the suction cups 51 and 52 to fix the metal reflective code disk, thus ensuring the stability of the metal reflective code disk material during the cutting process.
[0025] like Figure 2As shown, air passages 54 are provided at the bottom of suction cup 51 and suction cup 52. A cavity 55 is provided at the upper part of the cutting base 2. The bottom end of the air passage 54 extends into the cavity 55. A piston plate 56 is slidably connected inside the cavity 55. A round rod 57 is slidably connected to the outer surface of the piston plate 56, penetrating the piston plate 56. The two ends of the round rod 57 are fixedly connected to the two sides of the cavity 55 respectively. A spring 58 is fixedly connected to one side of the inner wall of the cavity 55. One end of the spring 58 is fixedly connected to one side of the piston plate 56. The spring 58 is sleeved on the outside of the round rod 57. A penetrating rod is fixedly connected to the middle of the piston plate 56 near the spring 58. A pull rope 519 extends from the outer surface of the cutting base 2. One end of the pull rope 519 extends through the cutting base 2 and is fixedly connected to a pull ring 59. Two hooks 517 are fixedly connected to the outer surface of the cutting base 2 near the pull ring 59. The outer wall of the upper hook 517 is movably fitted with the inner wall of the pull ring 59. Pulling the pull ring 59 will put it on the upper hook 517. During the process of pulling the pull ring 59, the piston plate 56 slides, thereby drawing the air inside the suction cup 51 and the second suction cup 52 into the cavity 55 through the air passage 54. With the help of the rubber ring 53, a double pressure can be formed at the suction cup 51 and the second suction cup 52, thereby further improving the fixing effect on the metal radial encoder.
[0026] like Figure 3 As shown, a groove 510 is provided at the top of the cutting base 2. A spring 512 is fixedly connected to the edge of the bottom of the groove 510. A sliding rod 511 is fixedly connected to the top of the spring 512. The outer wall of the sliding rod 511 is slidably connected to the inner wall of the groove 510. Under the reaction force of the spring 512, the sliding rod 511 slides upward inside the groove 510, thereby lifting the cut metal reflective encoder, thus facilitating material discharge and improving the safety of material discharge.
[0027] like Figure 3 As shown, a cavity 518 is provided at the lower part of the cutting base 2. A traction rope 513 is fixedly connected to the bottom end of the slide rod 511. The bottom end of the traction rope 513 extends into the cavity 518. A fixing ring 514 is fixedly connected to the bottom end of the traction rope 513. A traction rope 515 is fixedly connected to the outer wall of the fixing ring 514. The end of the traction rope 515 away from the fixing ring 514 extends out of the outer surface of the cutting base 2. A pull ring 516 is fixedly connected to the end of the traction rope 515 away from the fixing ring 514. The pull ring 516 is located directly below the pull ring 59. The inner wall of the pull ring 516 is movably fitted with the outer wall of the hook 517 located below. Pulling the pull ring 516 and fitting it onto the hook 517 below can stably store the slide rod 511 inside the slide groove 510.
[0028] like Figure 4As shown, the collection structure 6 includes a through hole 61 on the side of the cutting base 2 away from the pull ring 59. The through hole 61 passes through the cutting groove 3 and the cutting groove 4. A collection frame 62 is fixedly connected to the outer surface of the cutting base 2 near the through hole 61. An air pump 64 is fixedly installed at the bottom of the collection frame 62. After cutting, the air pump 64 is driven to draw the debris inside the cutting groove 3 and the cutting groove 4 into the collection frame 62 through the through hole 61, thereby cleaning the cutting groove 3 and the cutting groove 4.
[0029] like Figure 4 As shown, a filter frame 63 is inserted into the side of the collection frame 62 away from the through hole 61, and a cover plate 65 is fixedly connected to the side of the filter frame 63 away from the collection frame 62. The filter frame 63 is made entirely of a filter screen. The filter frame 63 can filter the cutting debris and then collect it, so as to facilitate cleaning.
[0030] like Figure 5 As shown, a locking rod 67 is slidably connected to the outer surface of the cover plate 65. A locking block 68 is fixedly connected to the side of the locking rod 67 near the collection frame 62. A locking hole 69 is opened on one side of the collection frame 62, penetrating the collection frame 62. The size and shape of the inner wall of the locking hole 69 are adapted to the size and shape of the outer wall of the locking block 68. A spring 66 is fixedly connected to the side of the locking block 68 away from the collection frame 62. The side of the spring 66 away from the locking block 68 is fixedly connected to the inside of the cover plate 65. Pressing down the locking block 68 compresses the spring 66, inserting the filter frame 63 into the collection frame 62. When the locking block 68 is aligned with the locking hole 69, under the reaction force of the spring 66, the locking block 68 is inserted into the locking hole 69, thereby fixing the filter frame 63 inside the collection frame 62, achieving the effect of easy installation and removal of the filter frame 63.
[0031] The working principle of this utility model is as follows: In use, the base 1 is installed on a suitable position such as a machine tool, and the metal reflective code disk material is placed on the cutting base 2. The material is cut along the first cutting groove 3 and the second cutting groove 4, thereby realizing the cutting processing of the metal reflective code disk. When the metal reflective code disk material is placed on the cutting base 2, the metal reflective code disk material is gently pressed, which causes the first suction cup 51 and the second suction cup 52 to fix the metal reflective code disk, thereby ensuring that the metal reflective code disk material is cut. To ensure stability during the cutting process, pull ring 59 is pulled to attach it to hook 517 above. As pull ring 59 is pulled, piston plate 56 slides, drawing air from suction cups 51 and 52 into cavity 55 via air passage 54. This, combined with rubber ring 53, creates pressure at suction cups 51 and 52, further enhancing the fixation of the metal radial encoder. After cutting, pull ring 59 and pull ring 516 are removed from hooks 517 respectively. Under the reaction force of spring 58, piston plate 56 slides, thereby eliminating the fixing effect on the metal reflective code disk. Simultaneously, under the reaction force of spring 512, slide rod 511 slides upward inside the slide groove 510, thereby lifting the cut metal reflective code disk, facilitating material discharge and improving discharge safety. During laser cutting, some debris falls into the cutting base 2 through cutting groove 3 and cutting groove 4. After cutting, the air pump 64 is driven to move cutting groove 3... The debris inside the cutting groove 2 4 is drawn into the collection frame 62 through the through hole 61, thereby cleaning the cutting groove 1 3 and the cutting groove 2 4. Press down the locking block 68 to compress the spring 3 66 and insert the filter frame 63 into the collection frame 62. When the locking block 68 is aligned with the locking hole 69, under the reaction force of the spring 3 66, the locking block 68 is inserted into the locking hole 69, thereby fixing the filter frame 63 inside the collection frame 62. At the same time, the cover plate 65 provides a certain sealing effect, thereby ensuring the air pump 64's air extraction effect.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
