Problems solved by technology

At present, the research in this area has only been reported as a deep hole processing accessory for the gun drilling system (external chip removal) designed by the British Hammond company, that is, the HD400 high-pressure cooling system, which can be used on ordinary lathes , the cutting oil is atomized through high-pressure air, and the atomized liquid is transported to the cutting area through the oil inlet channel in the middle of the rotary joint and the gun drill, cooling and lubricating the tool and helping chip removal, which greatly saves the amount of cutting oil used, but the system Only suitable for gun drilling system, drilling deep holes with small diameters, the use is limited, and it is difficult to popularize and apply

Abstract

The invention belongs to the technical field of machining, and in particular relates to an inner chip removal deep-hole machining rotary joint. The invention is a deep-hole machining rotary joint for an inner chip removal machining mode and is matched with a high-pressure atomizing device and an oil conveyer, namely a deep hole can be machined on a common lathe, and an inner chip removal mode is adopted for chip removal, so that the drill bit is well protected, and the machining precision of the hole is guaranteed; and moreover, a tool rotating and workpiece feeding mode is adopted in the machining mode, so that the machining range is widened. By the technical scheme, the rotary joint comprises a shell and a rotary component, wherein the rotary component comprises a rotating shaft, a conical sleeve, a spring collet and a locking nut; and the shell is sleeved on the rotating shaft of the rotary component.

Description

[0001] Technical field: [0002] The invention belongs to the technical field of mechanical processing, and in particular relates to a rotary joint for internal chip removal and deep hole processing. [0003] Background technique: [0004] In the machinery manufacturing industry, a cylindrical hole (inner cylindrical surface) whose hole depth exceeds 5 times the hole diameter is generally called a deep hole. Due to its hidden working area, narrow chip removal space, long chip removal channel, closed processing area, difficulty in cooling and lubrication caused by concentrated heat accumulation, and insufficient rigidity caused by slender rod workpieces and tool holders, deep hole machining has become a Machining technology with high processing difficulty and high degree of specialization requires the use of special deep hole processing equipment, cutting tools and cooling chip removal system. However, the deep hole processing equipment industry is in a monopoly state, and t...
