Problems solved by technology

[0003] Existing tools cannot directly process the stepped hole and the annular groove in the hole of the workpiece. Different tools need to be replaced for processing separately. The machining accuracy is low, and the machining operation is cumbersome, which increases the workload of the operator and the machining efficiency is low.

Embodiment Construction

[0023] The specific implementation manner of the present invention will be described in further detail below by describing the embodiments with reference to the accompanying drawings.

[0024] Such as Figure 1 to Figure 4 As shown, the integrated tool is processed in the hole, including a handle 1, a cutter body 2, and a forming blade, wherein the handle 1 is located at one end of the cutter body 2, and the forming blade is located at the other end of the cutter body 2, and the gap between the handle 1 and the cutter body 2 is The two are connected by a flange structure, which is convenient for disassembling and replacing the cutter body, and the cutter handle 1 is connected with the main shaft of the machine tool to fix the cutter on the processing machine tool.

[0025] The forming blade comprises a step hole forming reamer 3 and a groove forming knife 4, the groove forming knife 4 is fixed on the outermost end of the cutter body, and the step hole forming reamer 3 is fixed...

Abstract

The invention discloses a hole internal processing integrated cutter and a processing technique thereof. The cutter comprises a cutter handle, a cutter body and a forming cutter blade; the cutter handle is positioned at one end of the cutter body; the forming cutter blade is positioned at the other end of the cutter body; the forming cutter blade comprises a step hole forming reamer and a groove forming knife; the groove forming knife is arranged at the outer end of the cutter body; the step hole forming reamer is positioned at the inner side of the groove forming knife; the outer diameter of the step hole forming reamer is greater than the outer diameter of the groove forming knife. The processing technique comprises the following steps of positioning a to-be-processed workpiece, enabling a to-be-processed hole to be straight up, and fixing the cutter on a machine tool spindle; processing an annular groove in a manner that the cutter moves by virtue of circular interpolation; enabling the centers of the machine tool spindle and the cutter to return to the center of the to-be-processed hole, and processing a step hole in a manner that the cutter downwards performs cutting by virtue of linear interpolation; retracting the cutter. Replacement of different cutters is not needed, the positioning times of the cutter are reduced, the processing precision is improved, the processing process is simplified, and the processing efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of machining, in particular to an integrated tool for in-hole machining and a machining process thereof. Background technique [0002] The valve hole of the automobile steering gear housing is a stepped hole, and an annular groove is arranged inside the stepped hole. Currently, the stepped hole of the automobile steering gear housing and the annular groove in the stepped hole are processed separately by two different cutting tools, and the cutting tools need to be replaced during the processing. [0003] The existing tools cannot directly process the stepped hole and the annular groove in the hole of the workpiece, and different tools need to be replaced for processing separately. The machining accuracy is low, and the machining operation is cumbersome, which increases the workload of the operator and the machining efficiency is low. Contents of the invention [0004] Aiming at the deficiencies of the exi...
