Experience has shown that, in order to improve the processing efficiency of CNC machine tools, just "pick" the CNC machine tool fixture is not enough, you must also "good" CNC machine tool jigs.
Here are three commonly used methods:
Multi - station method
The basic principle of the multi-station method: By clamping more than one workpiece at one time, the unit clamping time can be shortened and the effective cutting time of the tool can be prolonged. A multi-station fixture is a fixture that holds multiple clamping locations.
With the development of CNC machine tools and user needs to improve production efficiency, multi-station fixture is now more and more applications. In the hydraulic / pneumatic fixture, the combination of fixtures, permanent magnetic fixture and precision combination of flat-nose clamp design of multi-station design more and more common.
Group use method
The same number of fixtures on the same table to use, the same can be achieved "multi-station" clamping purposes. This method involves the fixture generally should be "standardized design, high-precision manufacturing", otherwise it is difficult to achieve the requirements of CNC machining process.
Group use can take full advantage of CNC machine tool stroke, which will help the machine tool transmission components of the balanced wear; the same fixture can be used independently to achieve multiple fixtures,
Local quick change method
Partial quick change method is to change the fixture function or use mode quickly by changing part of the fixture (positioning tool, clamping tool, tool part and guiding tool) of CNC machine tool. For example: fast change combination of flat-nose pliers, can be achieved through the rapid replacement of jaw clamping function changes, such as clamping the material into a clamping bar; can also be quickly replaced by clamping components to achieve clamping changes, such as From manual clamping into hydraulic clamping. Local quick change method greatly shortens the time of replacing and adjusting the fixture, and the advantage is obvious in the small batch production.
