Problems solved by technology

[0004] The first purpose of the present invention is to overcome the problem that the existing conventional CNC machining center cannot bore the side of the annular groove on the stepped surface of the workpiece stepped hole, and provide a side feed machining tool that can effectively solve the conventional The problem that the side of the annular groove on the step surface of the workpiece step hole cannot be bored on the CNC machining center
[0005] The second purpose of the present invention is to overcome the fact that the boring tool of the existing tool with lateral feed function is a special tool. In the actual production process, too many boring tools will greatly increase the production cost; In the process of boring the side of the annular groove, the tool bar of the boring tool is easy to break. A side feed processing tool is provided. The boring tool has a wide range of applications and can be applied to many different boring surfaces. processing; and it can effectively improve the problem that the tool bar of the boring tool is easy to break during the boring process of the side of the annular groove, and improve the service life of the boring tool

Abstract

The invention discloses a lateral feeding machining cutter, and aims to provide the lateral feeding machining cutter which can effectively solve the problem that the conventional numeric control machining center cannot bore the side of an annular groove on a stage surface of a workpiece stage hole and is wide in application range. The lateral feeding machining cutter comprises a main shaft, wherein a radial hole is formed on the side of the main shaft; an axial hole communicated with the radial hole is formed on the end surface of the main shaft; a sliding block is arranged in the radial hole; a first groove opposite to the axial hole is formed on the side of the sliding block; one side, close to the bottom of the radial hole, of the first groove is an inclined guiding surface; a first reset spring is arranged between the bottom of the hole and the sliding block in the radial hole; a mandril is arranged in the axial hole in a sliding mode; one end of the mandril is extended into the first groove and presses against the inclined surface; the other end of the mandril is positioned outside the axial hole; a bearing coaxial to the main shaft is sleeved on the end of the main shaft; and a bearing seat is sleeved on the bearing.

Description

technical field [0001] The invention relates to a machining tool, in particular to a side feed machining tool. Background technique [0002] During the machining process, due to the large mass of the workpiece, it is inconvenient to locate on the ordinary lathe, so the annular groove on the side wall of the hole of this type of workpiece cannot be processed on the ordinary lathe; especially if Figure 5 As shown, the hole of the workpiece is a stepped hole and there is an annular groove 22 on the stepped surface of the stepped hole. When it is necessary to carry out boring processing on the side wall of the annular groove 22, not only ordinary lathes cannot process it, but also conventional CNC machining centers also cannot be processed. For example, yes Figure 5 Carry out boring on the side wall of the annular groove 22 in, the annular groove 22 is processed into Image 6 The dovetail groove 23 in the middle; this processing process cannot be processed on a conventional C...
