Abstract

The invention relates to a unit head structure of deep hole drilling machine. The front end part of an output shaft of a spindle motor extends into a hollow cavity of a motor mounting box body; an output shaft of the spindle motor is provided with a drive wheel; a spindle seat is fixed on a front box body and the spindle seat is internally connected with a spindle in a rotating way; a synchronous drive belt is fixed on a synchronous pulley and the drive wheel; the spindle is sheathed with a spindle bushing and is fixed with a tool holder clip. The invention is characterized in that shaft holes are arranged inside the spindle and the tool holder clip; a rotary joint is arranged in the rear end part of the shaft hole of the spindle; a gun drill is arranged in the front end part of the shaft hole of the tool holder clip; the gun drill is internally provided with a cooling liquid ejection hole communicated with the shaft holes of the spindle and the tool holder clip. With wide range of rotation speed, the invention can achieve 500 to 8,000r / min stepless speed regulation; with small structure, the motor can be arranged on the left side or right side of the rectangular box body according to the need; cooling liquid of 12MPa can pass through the spindle; the fixation of the gun drill is convenient and the axial fine regulation can be made.

Description

technical field [0001] The invention relates to a power head structure of a deep hole drilling machine. Specifically, the power head is a power element that drives a deep hole drill bit to rotate at high speed, and belongs to the technical field of deep hole drilling. Background technique [0002] In the existing technology, most of the power heads adopt ordinary frequency conversion motors, the speed is low (≤3000RPM), the precision is poor (large radial runout, large axial movement), the structure size is large, and the middle cannot pass high voltage Coolant. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art, to provide a high-speed rotation, high rotation accuracy, small structural size, and high-pressure cooling fluid in the middle of the rotating shaft. The power head structure of the deep hole drilling machine. [0004] According to the technical solution provided by the present invention, the ...
