Change of spring after unloading of spring collet

What are the capabilities of the Spring Collet:
The spring collet is made of alloy steel with good elasticity. After heat treatment, the outer cone of the head and the inner wall of the collet have high density to protect the strength and wear resistance. Each size of spring collet can clamp the workpiece in a very small size environment, so it is mostly used in self-propelled lathe and other efficient automatic machine tools. The combination of spring chucks is more real, rigid, able to bear large torque, eliminate the occurrence of loosening in rotation, use special performance of alloy steel energy, good durability, strong durability. Spring chucks are widely used as an elastic element in the machinery and construction industry, and the spring has relatively large elastic change in the absolute energy under load, so the mechanical The work or kinetic energy is converted into variable energy, and the change of spring disappears after unloading and returns to the original state.
Spring chuck is a very convenient thing, but there are many problems that can hinder its use. Almost the friction between the clamp and the thing under the gas mine is an important problem that affects whether the clamp is clamped. In almost cases, the larger the friction, the tighter the clamp, and the smaller the friction, the opposite.
First of all, it is the problem of his axis adjustment. Only when the action points of the big axis and the small axis are adjusted well, can the maximum clamping force be exerted. In view of the larger clamping force of the big axis and the smaller clamping force of the small axis, it is often important to adjust the length of the axis. However, there are too many small chucks in the East and West, and it is a general form that the clamping force is not tight.
