A spring chuck is a fixture used in milling machines to imprison drill bits or milling cutters, and is also a device for fixing parts that need to be modified. The following is the structural principle of the spring chuck that you share.
The collet is referred to as an elastic collet or bobbin clamp. A cylindrical clamp used to attach a drill bit or milling cutter to a milling machine. It is also a fixing device used to fix and reinforce parts that need to be modified.
function
① Limiting the movement of machinery, such as valve springs in internal combustion engines, limiting springs in clutches, etc.
② Absorb vibration and impact energy, such as buffer springs under cars and train compartments, and vibration absorbing springs in couplings.
③ Store and output energy as power, such as clock springs.
④ Used as a force measuring element, such as a force measuring device, a spring in a spring scale, etc. The ratio of load to deformation of a spring is called spring stiffness. The greater the stiffness, the harder the spring.
Structural principle
CNC milling machine spring collet (collet). A cylindrical clamp used to attach a drill bit or milling cutter to a milling machine. The utility model relates to a fixing device for fixing and reinforcing parts that need to be modified.
The structural principle is as follows: Install the chuck into the lock nut, and then lightly screw the lock nut with the spring chuck onto the tool handle, extension rod, or spindle. Be sure to clean the threaded parts of the spring collet and lock nut, as well as the fixing surface and cone surface. During the installation of the collet and locknut, the collet and locknut must be tilted at a certain angle, and then gently placed into the locking groove of the locknut.
