Embodiment
[0019] Embodiment: the chip breaking device used for shaft end face drilling in this scheme, such as figure 1 As shown, it includes a rotary sleeve, a fixed sleeve, an envelope 4 and a slideway sleeve 3. The fixed sleeve is located in the rotary sleeve. The first fixing mechanism includes two fixed plates. The two fixed plates are arranged symmetrically with respect to the center line of the device. The fixed plates are integrated There are threaded holes, and jacking bolts are installed in the threaded holes. The bottom of the rotary sleeve is processed with four inwardly inclined through holes 6, and the inner wall of the rotary sleeve is integrally formed with spiral blades 14. The second fixing device is two hoops, and the two hoops are fixed on the fixing sleeve. The outer wall of the fixed sleeve is integrally formed with two strip-shaped protrusions 2 that are symmetrical about the center line of the equipment. The inner wall of the envelope 4 is integrally formed with...

The invention belongs to the field special for part structure characteristics of boring machines or drilling machines, and particularly discloses a chip breaking device for shaft end surface drilling. The chip breaking device comprises a rotating sleeve, a fixed sleeve, a sealing sleeve and a slide way sleeve; the fixed sleeve is positioned in the rotating sleeve; a first fixing mechanism is arranged at the lower part of the rotating sleeve; multiple through holes are formed in the bottom of the rotating sleeve; spiral blades are arranged on the inner wall of the rotating sleeve; the fixed sleeve is provided with a second fixing device for fixing the fixed sleeve on a shaft; protrusions are arranged on the outer wall of the fixed sleeve; the sealing sleeve is positioned above the through holes; multiple swing pieces are hinged to the outer wall of the sealing sleeve; torsional springs are arranged in the hinged places of the swing pieces and the sealing sleeve; the sealing sleeve is provided with a stopper for preventing the swing pieces to swing upwards; the outer wall of the slide way sleeve is connected with the inner wall of the rotating sleeve; spiral slide ways corresponding to the swing pieces are formed in the inner wall of the slide way sleeve; and a support table is arranged at the bottom of the rotating sleeve, and is positioned at the lower parts of the swing pieces. The chip breaking device solves the problem of low automation level due to need of operators to break chips beside a drilling machine for a long time in traditional drilling operation.
Description
technical field [0001] The invention belongs to the field of structural features of components specially adapted for boring or drilling machines. Background technique [0002] The transmission shaft is mainly used to transmit torque, such as the long optical axis in the moving mechanism of the crane, the drive shaft of the car, etc. However, during operation, the transmission shaft will bear impact loads. In order to prevent the transmission shaft from breaking, it is necessary for the transmission shaft to have a certain elastic deformation capacity. Therefore, surface quenching is usually carried out on the shaft with certain elastic deformation ability, so that the surface has high strength, and the central part still has elastic deformation ability. [0003] In the drilling operation of materials with elastic deformation ability, in order to prevent the drill bit from breaking during the drilling process, the amount of feed into the hole is small at the beginning. When ...
