DEVICE FOR HONING PLANES WEDGES VALVES ARTILLERY SYSTEMS

Abstract

The article describes the process of honing the details of command artillery systems, in particular the process of honing planes wedge gate of medium-caliber guns. The article is an analysis of the kinematic scheme of the device and the selected gear ratio device that provides even wear a uniform honing stones and metal removal with a flat machined surface of the work piece due to the commission of the cutting grains honing stones complex movements in the horizontal plane. Next each of the cutting grains will not be repeated for the entire processing cycle. Kinematic diagram of the device with the established and enshrined in the radial grooves of the disc honing stones is implemented in the design and manufacture of devices for honing on vertical milling machines planes wedge gate artillery systems. Investigation of the process of honing the flat specimens made of high-strength gun steels viscous with plan dimensions 130x240 mm possible to determine the rational parameters of flat honing process.Production testing device for honing planes wedge gate of one of the artillery pieces on a vertical milling machine performed at one of the engineering confirmed the efficiency of the device for a flat honing. Honing wedge planes shutter serial products (76 mm caliber gun) on a vertical milling machine using the apparatus discussed in the article improves the processing performance in comparison with conventional processing means 20…35 %. In this case, stability is regulated product design documentation form accuracy and size of the part and the surface roughness of the planes of the wedge gate Ra £ 0,32 microns.
