Deep hole processing device

Abstract

The invention relates to a deep hole processing device and belongs to the technical field of oil transporting devices. A drill bit is firstly used for drilling a hole in advance in a designated position of the surface of a workpiece, then an aligning-sealing device in a fixing device is aligned with the hole opening, and the fixing device is fixed to the surface of the workpiece; a rotating devicein a driving device drives a toolbar to rotate through a key, the drill bit is used for drilling a hole in the workpiece, a negative-pressure chip discharging device enables negative pressure to be generated in a chip discharging cavity while drilling, the chip discharging cavity and the drilled hole are connected, and iron chips in the drilled hole are discharged under the action of negative pressure; meanwhile, cooling liquid in a cooling liquid storing cavity is sucked out by a cooling liquid pipeline in the toolbar under the action of negative pressure and then is discharged from a liquidoutlet in the drill bit, so that the drill bit is cooled; and a hydraulic rod drives the driving device to move in the drilling process, and therefore the toolbar is driven to deeply drilling the workpiece. According to the deep hole processing device, shaking during drilling is reduced, the drilling quality is improved, operation efficiency is effectively improved, and the service life of the drill bit is prolonged.

Description

technical field [0001] The invention relates to a deep hole processing device, which belongs to the technical field of oil feeders. Background technique [0002] Deep hole processing has always been an important part of mechanical manufacturing technology, and it is also one of the difficulties. By comparing and analyzing the statistical data in recent years, it is found that hole processing has accounted for about one-third of all machining, and about 40% of these hole processing is for deep hole processing. The so-called deep hole generally refers to a hole whose ratio of hole depth to hole diameter is greater than 5. Deep hole processing technology was first used in the production of military equipment, such as: gun barrels, gun barrels, etc. At the same time, this technology is in a closed development because it involves the military field. With the continuous development of economy and technology, deep hole processing technology has gradually turned to civilian applic...
