Abstract

The invention provides an engine lathe deep hole working device, which has simple structure, is convenient to use, can process a longhole of about phi 45mm and 4.2m deep on an engine lathe, improves the use ratio of the engine lathe, reduces the acquisition expenses of a heavy type deep hole drilling machine and greatly reduces the equipment cost. The device comprises a lathe bed of the engine lathe; one end of the lathe bed is provided with a main spindle box; and the other end of the lathe bed is provided with a tailstock. The device is characterized in that a center frame is arranged on the middle of the lathe bed, and between the main shaft and the tailstock; the front end of the tailstock is provided with a tailstock sleeve; the tailstock sleeve is internally provided with an extension arm; and the front end of the extension arm is provided with an auger bit in a connection mode.

Description

technical field [0001] The invention relates to the technical field of deep hole processing, in particular to a deep hole processing device for an ordinary lathe, which is mainly used for deep hole processing of heavy parts. Background technique [0002] Generally, a deep hole drilling machine is required to process deep holes, but for hollow rolls of continuous casting equipment, the roll dimensions are: Φ350×4500mm, the weight is 3.8 tons, and the center of the roll is Φ45 and the hole is 4.2 meters deep. Ordinary deep-hole drilling machines cannot perform deep-hole processing on this workpiece, and heavy-duty deep-hole drilling machines must be used to complete the deep-hole processing of this workpiece. However, heavy-duty deep-hole drilling machines have high cost and low utilization rate. Generally, processing companies do not specially configure heavy-duty deep-hole drilling machines. hole drilling machine. Contents of the invention [0003] In view of the above pr...
