Because the guide sleeve 7 is tightly propped against the surface of the workpiece, the cutting fluid can only continuously pass through the guide sleeve 7, and after leaving the guide sleeve 7, the cutting fluid and the cuttings are splashed to the periphery under the centrifugal effect. The conical surfaces at the right end tail parts of the guide sleeve seat 5 and the piston 11 are beneficial to guiding the cutting fluid to accelerate chip removal. And the front guide box 1 is downwards provided with a chip discharge port, so that the cutting fluid and the chips finally fall down under the action of gravity, and the chips are prevented from accumulating.
In a particular embodiment, the gun-drill 8 is brought into the workpiece for cutting, the high-pressure cutting fluid is discharged with the chips to the right along the V-groove of the gun-drill, and most of the cutting fluid and chips leave the gun-drill due to gravity and centrifugation, but still part of the cutting fluid continues to move along the V-groove. As shown in fig. 5, the middle hole of the oil baffle plate coincides with the deep hole drill bit, so that cutting fluid and chips are effectively prevented from flowing through the bearing sleeve during operation.
In a specific embodiment, when the deep hole drill 8 rotates at a high speed to cut, the deep hole drill pipe is subjected to axial force from the workpiece and the main shaft, so that the deep hole drill pipe is deformed in a flexing manner, and in a working condition of high-speed rotation, radial reciprocating swing is generated, so that the deep hole drill is vibrated strongly. When the vibrations are transmitted to the damping sleeve 19, most of the vibrations will be absorbed, thereby improving the accuracy of the drilling.
The foregoing description of the preferred embodiments of the invention is not intended to limit the scope of the invention, and all changes which may be made in the details of construction and the arrangement of the invention according to the description and the illustrations are intended to be included within the scope of the invention.
