Embodiment Construction

[0045] The embodiments of the present application are further described below, and the specific embodiments do not limit the present application in any way.

[0046] 1. The wedge-shaped protrusion is a connecting structure or an integral structure.

[0047] 2. The force of the liquid is adjusted by mechanical, electrical or magnetic means.

[0048] 3. The wedge-shaped profile of the wedge-shaped convex part is a circle, or an Archimedean spiral surface, a straight line, other curves, or a combination of the above lines.

[0049] 4. The cutting edge is arranged symmetrically or asymmetrically; single-edged or double-edged; the cutting fluid is oil or other liquid, which is filtered by a filter, centrifugal force, or magnetically.

[0050] 5. The wedge-shaped protrusion or the adjustment pad is in contact with the positioning piece.

[0051] 6. The material and heat treatment requirements of the top of the wedge-shaped protrusion are the same as or different from the material ...

Abstract

The invention belongs to the field of turning and boring, and particularly relates to a machining device capable of being used for a lathe or a boring machine to improve the machining capacity of thelathe or the boring machine. The device comprises a cutting edge part and a supporting part, wherein the cutting edge part is installed at the tail end or in the middle of the supporting part and located in a workpiece hole, the diameter of the supporting part is smaller than or equal to that of a hole, a plurality of wedge-shaped protrusions are distributed on the supporting part along the circumference, and wedge-shaped spaces are formed by the wedge-shaped protrusions and the inner wall of the machined deep hole, the highest point and the lowest point of the wedge-shaped protrusions are connected through a straight line or a curve, the cutting fluid flows to the wedge-shaped spaces and flows in from a large gap, flows out from a small gap or axially leaks to form a wedge-shaped oil filmwith pressure, the liquid or gas discharges chips out of the hole, the force of the liquid is large, the self-centering precision is high, the self-correcting effect is good, and vibration can be absorbed, the hydraulic pressure is convenient to estimate and can be adjusted as required, an adjusting device comprises a positioning piece, a screw rod and a support, and threads with different leadsare arranged on the screw rod.

Description

technical field [0001] The application belongs to the field of turning and boring processing, and specifically relates to a processing device that can be used for a lathe or a boring machine. Background technique [0002] When processing workpieces on lathes and boring machines, when the tool bar is long, problems such as chatter will occur in the processing system, and the tool bar is easily deformed. The same is true for grinding machines, honing machines and other machine tools. [0003] Bearings include rolling bearings and sliding bearings. Sliding bearings include dynamic pressure lubrication and static pressure lubrication. The working principle of dynamic pressure sliding bearing is different from that of static pressure lubrication, and its principle is enlightening. Inspired by the principle of dynamic pressure lubrication, Yu Daguo designed patents such as "a cutting tool with protrusions (ZL201520116320.3)". The following briefly introduces the basic knowledg...
