Description

A kind of fixture for copper pipe precision internal thread machining

Technical field

The utility model is related to copper pipe processing fields, especially a kind of fixture for copper pipe precision internal thread machining.

Background technology

Copper pipe is usually used in water supply pipe, heat supply and refrigeration piping, textured hard as installing pipe, not perishable, High temperature resistant, it is high pressure resistant the advantages that, can use in different environments.Copper pipe integrates the advantages of metal and non-metallic pipe, cold It comes out first in hot-water heating system, is best connecting pipe.Copper pipe fire resisting and heat-resisting remains to keep at high temperature its shape and strong Degree, there will not be aging phenomenon.The voltage endurance capability of copper pipe is several times or even tens times of plastic tube and aluminium-plastic pipe, it can bear Highest hydraulic pressure in current building.Under hot water environment, with the extension of service life, under the bearing capacity of plastic pipe is notable Drop, and the mechanical performance of copper pipe remains unchanged in all warm ranges of heat, therefore its voltage endurance capability will not reduce, and will not occur The phenomenon that aging.

In mechanical processing, screw thread is that (or bore area) is cut into cutter or grinding wheel on a cylindrical axis, Workpiece is gone around at this time, and cutter moves axially a certain distance along workpiece, and the trace that cutter is cut out on workpiece is exactly screw thread. Claim external screw thread in the screw thread that outer round surface is formed.Claim internal thread in the screw thread that bore area is formed.The basis of screw thread is circular shaft table The helix in face.There are many processing method of screw thread, can be on the lathes such as lathe, drilling machine, screw-thread miller, screw grinder using not Same tool is processed.The method of processing screw thread has：1. die methods, the method that screw thread is directly processed with mold；2. rolling Method makes workpiece generate processing method of the plastic deformation to obtain screw thread with forming roll die；3. cutting method refers to and uses forming tool Or the method that grinding tool processes screw thread on workpiece.Since cutting method is efficient, step is simplified, precision is high, screw thread process is got over Come it is more more be all to use Milling Process.But it is fixed to need will to be cut workpiece during the cutting process, and is unable to disfiguring workpiece, Therefore, there is very high requirement to copper pipe clamping device in copper pipe accurate thread process.
