What are the pressure devices in the CNC drilling machine

What are the pressure devices in the CNC drilling machine, let's go and see it:

1, section CAM pressure. The CAM and CAM corresponding to the convex and convex are arranged on the shaft and shaft sleeve respectively. When the transmission device rotates without load, the corresponding end CAM and CAM groove are completely chimed together to become a rigid coupling, so that the shaft sleeve and shaft rotate together; However, when the load is working, the CAM groove rotates relative to each other along the circumference with the action and change of the load, resulting in the relative axial displacement of the CAM sleeve, resulting in the surface compression of the friction element, and the size of the compression force changes with the size of the load, also known as automatic pressure.

2, spring pressure. Generally using cylindrical helical spring or butterfly bomb through its elasticity to make the main and slave friction elements working face to press each other. According to the structure, there are constant pressure and non-constant pressure.

3, in addition to the above pressure device, friction wheel drive can also use centrifugal force pressure, elastic ring pressure and swing gear type pressure, spiral gear, turbine and hydraulic pressure, air pressure and other mechanisms are also used as pressure devices.

4, steel ball (column) V-shaped groove pressure. A corresponding V-shaped groove is arranged on the circumference of the end face of the friction element and the transmission, and a steel ball (column) is placed on each groove. It is also an automatic pressurizing device with the same principle as the face CAM. Usually, the automatic compression type of face CAM compression or steel ball (column) V-groove compression device is used in conjunction with spring compression, and the pre-tension force is generated by the spring. The automatic compression device is generally installed on the shaft with large torque to ensure reliable compression.
