Deep hole drilling device

Abstract

A deep hole drilling device comprises a chip cleaner, an oil feeder and a hole drilling portion. The chip cleaner comprises a body and a connecting shaft, the connecting shaft is provided with a chip removing channel, and a chip removing hole is arranged on the body and is communicated with the chip removing channel; the hole drilling portion comprises an inner chip removing drill stem and an inner chip removing drill bit connected with the inner chip removing drill stem, the inner chip removing drill bit is provided with drill bit chip removing holes, the inner chip removing drill stem is a hollow stem, one end of the inner chip removing drill stem is connected with the connecting shaft, and the inner chip removing drill stem is communicated with the chip removing channel; and the oil feeder is sleeved on the outer portion of the inner chip removing drill stem, a first space is formed between the oil feeder and the inner chip removing drill stem, and an oil inlet is arranged on the oil feeder. When the hole drilling portion is drilled in a processed workpiece, a second space is formed between the outer wall of a drilled portion of the inner chip removing drill stem and the wall of a drilled hole, cooling liquid from the oil inlet sequentially flows through the first space and the second space, flows into the inner chip removing drill stem via the drill bit chip removing holes, and then flows into the chip removing channel, and then the cooling liquid and chips generated during hole drilling are mixed with each other and are drained via the chip removing hole.

Description

technical field [0001] The invention relates to a deep hole processing device, in particular to a deep hole drilling device. Background technique [0002] With the development of large-scale mechanical manufacturing equipment, it is often necessary to process deep holes with large diameters on large boxes. However, when processing deep holes, there are many internal cooling and chip removal processes, and the effect is not good, and the cooling and chip removal components complex structure. And, usually owing to be subjected to the restriction of existing processing equipment, make the deep hole on the large box body difficult to process. Therefore, it is necessary to provide a deep hole machining device capable of adequate cooling and chip removal, so as to facilitate the deep hole machining of large equipment boxes. Contents of the invention [0003] The object of the present invention is to provide a deep hole machining device to solve the problem of insufficient cool...
