[0002] PCBN composite sheet is a material synthesized by cubic boron nitride powder and cemented carbide under high temperature and high pressure. It has high hardness and wear resistance, as well as chemical inertness and does not react with iron group metals at high temperatures. Therefore, PCBN composite sheet is mainly used for cutting high-hardness materials and difficult-to-machine materials, such as hardened steel, high-alloy wear-resistant cast iron, pearlitic gray cast iron, high-temperature alloy, high-speed steel, surface-hardened alloy, sintered metal materials, etc.

[0003] Since PCBN composite sheets are used as cutting tools, most of the processed PCBN composite sheets are relatively thin and are very easy to break under the action of external force. During the transportation of PCBN composite sheets, if they are not adequately protected, they are easily damaged. To solve the above problems, we propose a PCBN composite sheet holding device.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0020] See also Figure 1-Figure 4 In this embodiment, a PCBN composite sheet holding device comprises a storage box 1, and a movable frame 7 is slidably connected to one side of the inner walls of both sides of the storage box 1 that are close to each other. A plurality of support plates 9 are welded to one side of the inner walls of both sides of the movable frame 7 that are close to each other, and a storage box 8 is placed on the bottom inner wall of the movable frame 7 of the upper level of the support plate 9. At the same time, the support plate 9 also plays a limiting role for the box cover 10 installed on the storage box 8, so that the box cover 10 can be opened. The four corners of the bottom of the movable frame 7 and the side of the bottom inner wall of the storage box 1 that are close to each other are fixedly installed with conical springs 2, which can squeeze the movable frame 7 upward. Eccentric wheels 4 that penetrate and extend into the interior of the storage box 1 are provided on both sides of the top of the storage box 1 to squeeze the movable frame 7 downward.

[0021] The top of the storage box 8 is provided with a fixing plate 3, and the side of the fixing plates 3 on both sides close to each other is rotatably connected to the rotating shaft 6. The eccentric wheel 4 is fixedly mounted on the outer rings of the rotating shaft 6 on both sides, and a pull rod 5 is fixedly mounted on the rotating shaft 6. By pulling the pull rod 5, the eccentric wheel 4 can be driven to rotate through the rotating shaft 6. A box cover 10 is installed on the top of the storage box 8, which can seal the storage box 8. A placement groove is provided on the top surface of the storage box 8, and a protective ring 12 is installed in the placement groove. A protective pad 13 is fixedly installed on the inner side of the box cover 10, which can protect the PCBN composite sheet through the protective ring 12 and the protective pad 13. A groove is provided in the middle and lower part of the front of the storage box 8, and a handle 11 is installed on the top inner wall of the groove. By pulling the handle 11, the storage box 8 can be pulled out of the storage box 1. A plurality of through holes are provided on the front of the storage box 1, and the through holes match the storage box 8, so that the storage box 8 can be conveniently inserted into the storage box 1.

[0022] The working principle and use process of the present invention are as follows: the PCBN composite sheet containing device can first pull the pull rod 5, which can drive the eccentric wheel 4 to rotate through the rotating shaft 6, so that the eccentric wheel 4 can squeeze the movable frame 7, and the movable frame 7 moves downward. At this time, the containing box 8 can be moved to the through hole opened in the storage box 1. Then, by pulling the handle 11, the containing box 8 can be pulled out of the storage box 1, and the box cover 10 can be opened, and the PCBN composite sheet can be placed in the placement groove opened in the containing box 8. Since the placement groove opened in the containing box 8 is equipped with a protective ring 12, and the box cover 10 is also equipped with a protective ring 12, the protective ring 12 is installed in the storage groove, and the protective ring 12 is installed in the box cover 10. Equipped with a protective pad 13, when the box cover 10 is closed, the protective ring 12 and the protective pad 13 can protect the PCBN composite sheet to avoid damage. After the PCBN composite sheet is placed, the storage box 8 can be inserted into the storage box 1 through the through hole opened in the storage box 1. After that, the pull rod 5 can be pulled, and the eccentric wheel 4 can be reset through the rotating shaft 6. At this time, under the action of the conical spring 2, the movable frame 7 can be moved upward. At this time, the storage box 1 can protect the storage box 8, and further protect the PCBN composite sheet in the storage box 8.
