Embodiment 1

[0048] In this embodiment, a dynamic balance compensation module that cooperates with the linearly moving sliding seat is added. When the sliding seat performs reciprocating linear motion on the end surface of the rotating disk C1, the driving rods D3 on both sides of the sliding seat perform reciprocating linear motion synchronously. At the same time, the lever D3 will push the movable ball D4 in the chassis D1 to circulate and roll in the circuit groove. The movable ball D4 will not only play the role of pressing against the lever D3, but also cooperate with the movement of the lever D3 to form a supplementary measure of dynamic balance. , so that the dynamic balance of the boring device can be compensated online, the vibration can be suppressed, and the quality of the boring process can be guaranteed.

[0049] As an optional embodiment, the circuit groove includes a connected linear groove D7 and an arc groove D8. The linear groove D7 communicates with the strip-shaped guide...

Abstract

The invention discloses an adjustable boring device. The adjustable boring device comprises a cutter handle connecting module, a motion conversion module and a radial moving module which are connected in sequence. The motion conversion module comprises a torque transmission mechanism, the torque transmission mechanism is used for driving the radial movement module to rotate, a planet wheel driving mechanism is arranged in the torque transmission mechanism, the output end of the planet wheel driving mechanism is connected with a connecting cylinder, and the outer edge of the connecting cylinder is connected with a diameter adjusting rocker; the planet wheel driving mechanism is used for driving the connecting cylinder to do autorotation motion and do revolution motion around the center of the planet wheel driving mechanism at the same time; the radial moving module comprises a rotating disc connected with the torque transmission mechanism, a strip-shaped limiting groove is formed in the rotating disc, the diameter adjusting rocker movably penetrates through the strip-shaped limiting groove and is movably connected with a sliding seat, the sliding seat is slidably connected to the face, away from the motion conversion module, of the rotating disc, and a boring cutter is connected to the sliding seat. The adjusting device has the advantages that the overall structure is simplified, and the adjusting precision is improved.

Description

technical field [0001] The present application relates to the technical field of machining equipment, in particular to an adjustable boring device. Background technique [0002] Boring is a mechanical processing method for further processing forged, cast or drilled holes, expanding the aperture, improving precision, reducing surface roughness, and correcting the axis deviation of the bottom hole. According to the principle of relative motion, when boring, the workpiece can be rotated without rotating the boring tool, or the workpiece can not be rotated and the boring tool can be rotated. The former requires simple and regular workpieces, which can be realized on ordinary lathes, but only a small part of the actual processing scene. In actual production, most of the workpieces have complex shapes and characteristics, and are difficult to rotate, or even not allowed to be rotated. Therefore, the method of rotating the boring tool without rotating the workpiece is the absolute...
