Non-standard three-tool-bit shank structure for aluminum shell machine base machining

Abstract

The invention discloses a non-standard three-tool-bit shank structure for aluminum shell machine base machining. The structure comprises a three-tool-station shank and aluminum shell machining tool blades, wherein three blade installing grooves are milled in the head part of the three-tool-station shank, the shape of the blade installing grooves is matched with the shape of the corresponding aluminum shell machining tool blades, the aluminum shell machining tool blades are fixedly connected with the three-tool-station shank through blade installing screws, and the installing screws are screwedinto installing screw holes in the blade installing grooves. The structure has the advantages that the operation is simple, the problem that the aluminum shell machine base requires tool replacementfor multiple times during machining in the prior art is solved, one shank is provided with the three blades, the machining efficiency of the aluminum shell machine base is improved, and the problems that the aluminum shell machine base is long in production period, high in operating labor intensity, high in production cost and large in machining tool model specification are solved. All machining surfaces of the machine base are machined through the promoted process of one-time clamping and one-tool machining, so that the repeated positioning errors are reduced, the concentricity of machining of the machine base is improved, and the machining quality of the machine base is improved.

Description

Technical field

[0001] The invention relates to a non-standard three-head tool holder structure for machining an aluminum shell machine base. Background technique

[0002] In the current tool industry, ordinary standard tools are the dominant tool, and special non-standard tools are rarely produced. Due to the production cycle and cost, many good processes cannot be implemented. It is impossible to process many parts with only one tool, and multiple tool changes and adjustments are required to complete the part processing.

[0003] For example, in the processing of aluminum housings in the prior art, the current common processing technology is: first process an end face, stop, and white section at one end, and then perform secondary clamping, and position the other end with the processed end stop. The end face, the spigot, the white section, and the iron core gear; each processing requires two knives for processing, one for the end face, and the other for the inner hole. It is imp...
