Abstract

The invention relates to a long-axis deep hole drilling device and method for removing chips through circulating water. The device comprises a lathe, a deep hole drill bit, a water inlet unit and a water drainage unit. The water inlet unit is composed of a water inlet device and a first feeding device. The water drainage unit is composed of a water drainage pipe and a second feeding device. The water inlet device comprises a shell, a rotary water inlet barrel, a front end sleeve and a wedge-shaped sealing sleeve. The first feeding device and the second feeding device can both conduct feeding movement in the longitudinal direction of the lathe. According to the long-axis deep hole drilling device and method, the drilling procedure is simplified, a good effect is achieved on deep hole drilling of long-axis parts, and the drilling precision, coaxiality and in-hole surface roughness can be guaranteed; and the problem of poor sealing performance of a circulating water path of existing deep hole drilling equipment is solved, and the chip removal capacity during drilling is greatly improved.

Description

technical field [0001] The invention relates to the technical field of deep hole processing, in particular to a long-axis deep hole drilling device and method for circulating water chip removal. Background technique [0002] Drilling is one of the basic processing methods in mechanical manufacturing. The commonly used drilling equipment includes three types: desktop drilling machine, vertical drilling machine and radial drilling machine. In addition, hand drills are also commonly used drilling tools. With the development of mechanical equipment, higher requirements are put forward for the accuracy and depth of drilling. In order to meet the requirements of higher precision and extreme drilling conditions, deep hole drilling has gradually been developed in mechanical manufacturing. However, most of the existing deep hole processing equipment needs to drill pilot holes before processing, the sealing of water circulation is poor, the process is relatively cumbersome, and it can...
