[0002] "PDC" is the abbreviation of polycrystalline diamond compact bit, which is a kind of diamond material bit. It is an integral bit, and the bit components are not likely to fall off during drilling. It mainly relies on the cutting action of PDC compacts to break rocks, similar to the cutting principle of a drag bit. During drilling, it has a small torque, good stability, high mechanical drilling speed under a small bit weight and high rotational speed. During the production process of the bit, it is necessary to fix the position of the bit to carry out a series of inspection work.
[0003] However, the existing tooling fixture has a weak fixed adjustment function, and it is difficult to carry out processing and inspection work on bits of different specifications during the production process and difficult to adjust the angle of the bit, resulting in low work efficiency. The adjustment effect of the existing tooling fixture is poor. When adjusting the positions of multiple bits simultaneously during use, it causes the staff to adjust the positions of the bits one by one during the work process, affecting the practicality of the device.
