[0002] Boron nitride is a crystal composed of nitrogen atoms and boron atoms, with a chemical composition of 43.6% boron and 56.4% nitrogen. It has four different variants: hexagonal boron nitride HBN, rhombohedral boron nitride RBN, cubic boron nitride CBN and wurtzite boron nitride WBN. Boron nitride was introduced more than 100 years ago. The earliest application was hexagonal boron nitride as a high-temperature lubricant, referred to as h-BN, or a-BN, or g-BN, that is, graphite boron nitride. h-BN is very similar to graphite in both structure and performance, and it is white, so it is commonly known as white graphite.

The loading and unloading of boron nitride is generally done by manual pick-up and placement. Employees are prone to contact with processing equipment and suffer various injuries, which reduces the personal safety of employees. Therefore, the utility model proposes a fixture for boron nitride processing to solve the above problems. Utility Model Content

[0018] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with an embodiment. The embodiment is only used to explain the present invention and does not constitute a limitation on the protection scope of the present invention.

[0019] according to Figure 1 , 2 As shown in Figures 3 and 4, this embodiment proposes a fixture for boron nitride processing, including a main frame 1, a rotating shaft 2 and a rotating arm 3. A group of rotating shafts 2 are symmetrically fixedly connected to both sides of the main frame 1, and a rotating arm 3 is hinged at one end of the rotating shaft 2. The bottom end of the rotating arm 3 is fixedly connected to a clamping block 4. The top of the main frame 1 is fixedly connected to a support rod 5. An adjusting mechanism is provided on the outer side of the support rod 5. The support rod 5 is held and the clamping block 4 is pulled upward by the adjusting mechanism to rotate the two clamping blocks 4 apart, and then the center of the clamping block 4 is aligned with the center of the cylindrical boron nitride product. Then the adjusting mechanism pushes the clamping block 4 to rotate downward to close the two clamping blocks 4 together to clamp the boron nitride product. This is because the cylindrical boron nitride product can be driven in and out by this clamp. The clamp has a certain length to prevent employees from directly contacting the processing device, thereby improving their own safety.

[0020] The shape of the clamping block 4 is set to be a semicircular arc structure, and the adjacent sides of the two clamping blocks 4 are connected in a close fit, and the center line of the support rod 5 is vertically parallel to the center position of the clamping block 4.

[0021] The adjustment mechanism includes a sliding frame 6, an articulated rod 7, a pull rod 8 and a top seat 10. The sliding frame 6 is slidably installed on the outer side of the support rod 5. A group of articulated rods 7 are symmetrically hinged on both sides of the sliding frame 6. The bottom end of the articulated rod 7 is hinged to the top of the clamping block 4 through a pin shaft. The pull rods 8 are symmetrically fixedly connected to the two sides of the sliding frame 6. The top of the pull rod 8 is fixedly connected to the top seat 10. When the employee holds the support rod 5 with one hand and the top seat 10 with the other hand, the top seat 10 is fixed to the sliding frame 6 through the pull rod 8, so the sliding frame 6 can be pulled upward through the top seat 10. The sliding frame 6 is hinged to the clamping block 4 through the hinge rod 7, and one side of the clamping block 4 is hinged to the rotating shaft 2, thereby pulling the clamping block 4 to rotate upward around the rotating shaft 2, and then driving the two clamping blocks 4 to separate from each other. When the center of the clamping block 4 coincides with the cylindrical boron nitride product, the sliding frame 6 is pushed downward by the top seat 10, and the sliding frame 6 drives the clamping block 4 to move downward through the hinge rod 7. The two clamping blocks 4 are closed together to clamp the cylindrical boron nitride product, which is convenient for employees to drive the cylindrical boron nitride product in and out through the clamp, and the clamp is long enough to keep employees away from processing equipment to improve their own safety.

[0022] A damping block 15 is provided at the top of the support rod 5, and a sliding rod 16 is slidably installed inside the damping block 15. The top of the sliding rod 16 is fixedly connected to the base 11, and the outer side of the sliding rod 16 is sleeved with a spring 9. The top seat 10 and the base 11 are parallel in position up and down, and have the same shape and size. A baffle larger than the diameter of the spring 9 is fixedly connected to the top of the support rod 5. When the top seat 10 moves downward, it will contact the base 11 and squeeze it to move downward, thereby driving the sliding rod 16 and the spring 9 to move downward. The sliding rod 16 and the damping block 15 rub against each other to consume the kinetic energy of the base 11. The spring 9 generates an upward elastic force to drive the base 11 to move upward and reset, so as to reduce shock for the top seat 10.

[0023] A hook 12 is provided on the top of the top seat 10, and a hanging ring 13 is provided on the top of the hook 12. A mounting hole is provided inside the hanging ring 13, and a locking mechanism is provided on one side of the hook 12. The locking mechanism includes a threaded rod 17 and a nut 14. One side of the hook 12 is provided with an opening, and a threaded rod 17 is hinged on the bottom of the opening. A groove is provided on the top of the opening, and the top of the threaded rod 17 passes through the inside of the groove and is threadedly connected with the nut 14. The screw is knocked into the wall through the mounting hole to fix the hanging ring 13 on the wall, and the nut at the top of the threaded rod 17 is loosened so that it no longer clamps the threaded rod 17 and the hook 12, and the threaded rod 17 is rotated outward to make the opening on one side of the hook 12 leak out. After the hook 12 is hung on the hanging ring 13, the threaded rod 17 is rotated to reset so that its top passes through the groove at the top of the opening, and finally the nut at the top of the threaded rod 17 is tightened to connect the hook 12 and the hanging ring 13 together, so that the fixture can be hung on the wall for storage.

[0024] The boron nitride processing fixture is configured such that when an employee holds the support rod 5 with one hand, he holds the top seat 10 with the other hand. Since the top seat 10 is fixed to the sliding frame 6 by the pull rod 8, the sliding frame 6 can be pulled upward by the top seat 10, and the sliding frame 6 is hinged to the clamping block 4 by the hinge rod 7, and one side of the clamping block 4 is hinged to the rotating shaft 2, thereby pulling the clamping block 4 to rotate upward around the rotating shaft 2, thereby driving the two clamping blocks 4 to separate from each other. When the center of the clamping block 4 coincides with the cylindrical boron nitride product, the sliding frame 6 is pushed downward by the top seat 10, and the sliding frame 6 drives the clamping block 4 to move downward by the hinge rod 7, and the two clamping blocks 4 are closed together to clamp the cylindrical boron nitride product, so that the employee can drive the cylindrical boron nitride product in and out through the clamp, and the clamp is long enough to keep the employee away from the processing equipment to improve their own safety.

Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principles of the utility model.
