Embodiment Construction

[0045] The implementation of the present application will be further described below, and the specific implementation does 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 adjusting 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 th...

Abstract

The invention belongs to the field of turning and boring, and particularly relates to a hole machining method for a lathe or a boring machine. The machining capacity of the lathe or the boring machinecan be improved. The hole machining method uses a machining device with a cutting edge part and a supporting part. The cutting edge part is located in a workpiece hole. The diameter of the supportingpart is smaller than or equal to that of the hole, a plurality of wedge-shaped protrusions are distributed on the supporting part along the circumference, and a wedge-shaped space is formed by the wedge-shaped protrusions and the inner wall of the machined deep hole. Cutting fluid flows to the wedge-shaped space, and a wedge-shaped oil film with pressure is formed. A hydraulic adjusting device comprises a positioning piece, a screw rod and a support. Threads with different leads are arranged on the screw rod. Liquid or gas discharges chips out of the hole. The machining method comprises the steps that firstly, a machining device is assembled; secondly, the machining device and a workpiece are installed on a machine tool; and thirdly, the cutting edge is rotated relative to the workpiece.The machining device is large in liquid force, high in self-centering precision, good in self-correcting effect and capable of absorbing vibration, and hydraulic force is convenient to estimate.

Description

technical field [0001] The application belongs to the field of turning and boring processing, and in particular relates to a hole processing method 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 knowledge of dynami...
