Cutter adjusting device and cutter adjusting method of hole series finish machining cutter shaft

Abstract

The invention belongs to the technical field of machining and provides a novel cutter adjusting device and a cutter adjusting method of a hole series finish machining cutter shaft. The cutter adjusting device comprises a cutter body (1), a cutter holder (2) and cutter blades (4); a cutter setting reference rod I (5) is arranged at the front end of the cutter body (1); the cutter adjusting device further comprises a dial indicator (7), a V-shaped member assembly (6) and a cutter setting block (8); a cutter setting reference rod II (9) is arranged at the front end of the cutter setting block (8); the size of the cutter setting reference rod II (9) is the same as that of the cutter setting reference rod I (5); the rear end of the cutter setting block (8) is provided with a cylindrical cutter setting surface; the dial indicator (7) is installed on one side of the upper portion of the V-shaped member assembly (6); the V-shaped member assembly (6) is matched with the cutter setting reference rod I (5) and the cutter setting reference rod II (9); and the lower portion of the V-shaped member assembly (6) is provided with a right angle V-shaped groove which is opened downwards. The cutter adjusting device and the cutter adjusting method have the advantages of being short in time consumption, few in errors, high in accuracy and low in rejection rate.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, and in particular relates to a tool adjusting device and a tool adjusting method for a hole system finish machining tool shaft. Background technique [0002] At present, polygonal blades or blades are used in the industry (the blades are triangular, diamond-shaped or square, etc., which are cut by the rounded corners on the shape of the blades; the blades are cylindrical blades that have been obliquely cut. When the hole system is finished machining, with the accumulation of the number of workpieces or times, the tool will be worn to varying degrees, and the processing size will also change. When the size changes to a certain range, its The processing size cannot meet the process size of the product. At this time, the tool must be replaced or adjusted. The tolerance zone of this type of finishing hole process size is mostly 0.01mm ~ 0.033mm, the tool adjustment must be adjusted by ...

AI Technical Summary

Problems solved by technology

[0008]2. It takes a long time to adjust the knife, and often needs to be adjusted repeatedly, which seriously restricts the production efficiency during assembly line production;

[0009]3. The equipment must have enough space for installing dial indicators and related accessories;

[0010]4. When the size is corrected after the trial machining is completed, if the installation datum of the dial gauge is offset or the front and rear reference datums are inconsistent, the adjustment error of the secondary adjustment will occur , easy to produce industrial waste;

[0011]5. When the blade or the tip of the knife is damaged and needs to be replaced with a new one, there is no size reference, and the adjustment of the knife becomes complicated

[0016]2. There are assembly errors in the disassembly and installation of the cutter body. Once an error occurs, a second adjustment of the cutter is required, which is time-consuming and laborious, and the original method of adjusting the cutter by replacing the cutter body method has no effect at all;

[0017]3. Repeated disassembly and assembly will destroy the assembly hole on the spindle of the cutter body
