Problems solved by technology
[0002] The size of the spool nozzle parts is generally relatively small, and requires high dimensional accuracy and shape accuracy during use, and the inner surface of the spool nozzle requires high surface quality, that is, a small surface roughness value, which is generally traditional It is difficult to realize the use requirements of the valve core nozzle with advanced processing technology
Moreover, the surface quality of the small hole at the valve core nozzle will directly affect its working performance. When the inner wall of the small hole of the valve core nozzle has burrs, is not smooth enough or residual pollutants, it is easy to cause the jet of the valve core nozzle to scatter and spiral, affecting the work. performance

The invention provides valve element nozzle abrasive particle flow precision machining equipment which is composed of an upper bottom plate, a forward circulation device, a reverse circulation device,a fixing disc, an upper supporting cylinder, a lower supporting cylinder, a left matching sleeve, a right matching sleeve and a lower bottom plate. The forward circulation device is composed of a forward upper flow channel pipe, a forward positioning disc, a forward piston, a forward spring, a forward spring limiting gasket, a forward spring adjusting screw and a forward lower flow channel pipe.The reverse circulation device is composed of a reverse upper flow channel pipe, a reverse positioning disc, a reverse piston, a reverse spring, a reverse spring limiting gasket, a reverse spring adjusting screw and a reverse lower flow channel pipe, and the forward circulation device and the reverse circulation device are matched with each other, so that abrasive flows in from the upper end of avalve element nozzle and flows out from the lower end of the valve element nozzle during forward and reverse circulation. The sharp edge of the lower end of the valve element nozzle can be prevented from being damaged, and meanwhile machining efficiency is high.
Description
technical field [0001] The invention relates to the technical field of abrasive flow processing, in particular to an abrasive flow precision machining spool nozzle device. Background technique [0002] The size of the spool nozzle parts is generally relatively small, requiring high dimensional accuracy and shape accuracy during use, and the inner surface of the spool nozzle requires high surface quality, that is, a small surface roughness value, which is generally traditional It is difficult to realize the use requirements of the valve core nozzle with advanced processing technology. Moreover, the surface quality of the small hole at the valve core nozzle will directly affect its working performance. When there are burrs, not smooth enough or residual pollutants on the inner wall of the small hole of the valve core nozzle, it is easy to cause the jet of the valve core nozzle to scatter and spiral, affecting the work. performance. [0003] Abrasive flow processing is a kind...
