Description

Special Rotary Fixture for Ultrasonic Vibration Assisted Gun Drilling

technical field

The invention relates to a rotary fixture, in particular to a special rotary fixture for ultrasonic vibration-assisted gun drilling.

Background technique

Gun drilling belongs to the deep hole processing tool with external chip removal. It is an important processing method for processing small deep holes with a diameter of less than 6mm. It is a tool that can obtain good surface roughness and precision holes with one drilling. The rotary fixture used in gun drilling is widely used because of its small size and the ability to keep supplying coolant to the tool continuously while rotating. However, the rotary fixtures used in the existing gun drilling process all adopt the Morse taper shank connection method, which requires the corresponding Morse taper hole device to cooperate, so the price is expensive and it is inconvenient to connect with the machine tool, and it is used for ultrasonic A large amount of vibration energy will be lost during vibration-assisted gun drilling, which will greatly reduce the processing efficiency, reduce the tool life, and is not conducive to the transformation of the machine tool.

Contents of the invention

In order to make up for the shortcomings of the existing rotary fixture used in ultrasonic vibration-assisted gun drilling, the present invention designs a rotary fixture with simple connection structure, low ultrasonic vibration energy loss, high processing efficiency and simple structure, easy to be used for machine tool transformation and low price. special rotating fixture.

The object of the present invention is achieved by the following technical measures:

A special rotary fixture for ultrasonic vibration-assisted gun drilling, the device includes a rotating shaft with a flange, a flange sleeve I, a flange sleeve II, a flange sleeve III, a gasket I, a gasket II and an outer sleeve, The rotating shaft with flange is coaxial with flange sleeve I, flange sleeve II, flange sleeve III and outer sleeve, and the flange sleeve I is set on one end of the rotating shaft with flange. One end of the flange sleeve I is connected with one end of the flanged rotating shaft, the washer I and the flange sleeve II through a screw, and the other end of the flange sleeve I is connected with the outer sleeve through a bearing, and the flange sleeve The other end of the cylinder II is connected to the washer II and the flange sleeve III set on the other end of the rotating shaft with the flange through a screw, and the flange sleeve III is connected to the outer sleeve through a bearing, and the outer sleeve is provided with an inner The groove I is sealed and connected with the flange sleeve II through the seal ring embedded in the inner groove I, and the flange sleeve II is provided with the inner groove II and passed through the sealing ring embedded in the inner groove II The ring is sealed with the flanged rotary shaft.

One end of the rotating shaft with flange is provided with a light hole in the direction of the axis line of the rotating shaft with flange, the other end is provided with a threaded hole, and a coolant channel I is opened in the middle. A coolant channel II is opened in the direction of the axis line of the rotating shaft with a flange and communicates with the coolant channel I. A threaded hole is opened on one side of the outer sleeve, and a coolant channel III is opened on the other side and connected to the coolant channel. The channel II is coaxial, and the flange sleeve II is provided with a cooling liquid channel IV and a cooling liquid groove. The cooling liquid channel IV communicates with the cooling liquid groove and is coaxial with the cooling liquid channel II.

Compared with the prior art, the special rotary fixture for ultrasonic vibration-assisted gun drilling not only satisfies the continuous supply of cooling liquid for the rotary tool, but also uses double-headed studs to connect with the ultrasonic vibrator. The connection structure is simple, easy to process and low in cost. Low, the structure of the fixture can transmit the ultrasonic vibration energy to the tool to the greatest extent, which improves the processing efficiency, processing quality and tool life; if it is used for ordinary gun drilling processing, it only needs to replace the double-ended stud with a threaded one. The clamping device is enough, which greatly facilitates the transformation of the machine tool.
