Spring chuck reduces long wear and increases clamping force

The common requirement of spring chuck for superior skill of fixture is that the structure of most fixture should be selected as many standard parts and extensive parts as possible, and the proportion of special parts should be as small as possible, so as to reduce the production labor and cost. The special structure and component configuration of spring chuck should be easy to make and calculate, and easy to arrange and debug.

The adjustability of spring chuck structure is often selected by using bolt fastening, pin position form, changing and arranging fixture, which can be used to grind a part simply. It can also control the length of the arrangement by placing a change washer, changing the gasket or adjusting sleeve between the parts and components, compensate the errors of other parts, and improve the precision of fixture. Once the layout standard has been processed, its location and length should not be changed. Therefore, these surfaces or lines which need to be changed or repaired during the layout process can not be used as layout standards.
In practice, spring chuck should often be loosened and replaced. For example, it can be used in turning center. When it is loosened, a layer of smooth agent can be sprayed on the inner hole of spring chuck. Conditionally, the coolant used is very smooth and smooth, which can wash debris on spring chuck and provide a good smooth effect. Punctual application of smooth grease at the locking angle of spring chuck can reduce long-term wear and increase clamping force. Other materials with good smoothness and flatness can also be used, including good grease or wax substrates with EP (extreme burden) properties.
Spring chuck
Reasonable selection of clamping diameter and length level of spring chuck can ensure that the spring chuck has a large clamping force on the workpiece, and the clamping conditions at the end, and then ensure the good and high precision of mechanical processing. Assuming that the inner aperture length of the spring chuck is too large, the workpiece is clamped only by the orifices of the spring chuck when the chuck closes.
It is quite possible that the spring chuck generates a mismatch between the outer circle of the workpiece and the inner hole of the spring chuck, thus reducing the clamping force. Assuming that the length of the inner aperture of the spring chuck is too small, only the inner hole of the chuck is touched by the workpiece when the chuck closes, the clamping force will be enhanced, but the conditions of different axes between the chuck and the workpiece will be created. A class of level spring chucks can only locate the corresponding diameter and length of the workpiece.
