Modular mechanical clamp type stepped reamer

Abstract

The invention discloses a modular mechanical clamp type stepped reamer which comprises a module type reamer head, a single-blade guide bar type reamer bar and a connecting flange, the single-blade guide bar type reamer bar comprises a second end face, a conical inner hole, an inner threaded hole, a second cooling water hole and a hard alloy supporting bar, and the left end of the single-blade guide bar type reamer bar is provided with a module type reamer head in a threaded mode. Through the effects of a cone, an external thread, a first end face, a second end face, a conical inner hole, the internal thread hole, a first alloy cutting edge, a second alloy cutting edge, an adjusting cushion block, an adjusting screw, a mechanical clamping type cutting edge, a first cooling water hole, the second cooling water hole and a third cooling water hole, problems that due to diversification of parameters such as the diameter size, the machining length and machined materials and high coating cost of an existing stepped hole reamer, a traditional stepped hole reamer of an integral welding type structure is high in manufacturing cost and does not meet the use requirements of people are solved.

Description

technical field [0001] The invention relates to the technical field of reamers for mechanical processing, in particular to a modular machine clip type stepped reamer. Background technique [0002] With the development of modern manufacturing industry, more and more customers have higher and higher requirements for processing large-diameter stepped holes, such as dimensional tolerances, shape tolerances, and roughness. In order to ensure the consistency of processing dimensions when processing high-precision stepped holes , The overall welded structure represents the structural form of the traditional stepped hole reamer in the current market. [0003] The applicant found that there are at least the following technical problems in the prior art: the existing step hole reamer is due to the diversification of parameters such as diameter size, processing length, and processed materials, as well as the high cost of coating, which leads to the traditional integral welded structure...

Problems solved by technology

[0003] The applicant found that there are at least the following technical problems in the prior art: the existing step hole reamer is due to the diversification of parameters such as diameter size, processing length, and processed materials, as well as the high cost of coating, which leads to the traditional integral welded structure. The manufacturing cost of the step hole reamer is relatively high. At present, the welded cylindrical shank, Morse taper shank and sleeve interface reamer are mainly used in China. Although the price is low, the processing efficiency is low, the processing quality is poor, and the service life is low. And the biggest disadvantage of integral and welded stepped hole reamers is that once a certain diameter of the tool is out of tolerance, even if the other diameters are qualified, the tool must be replaced or scrapped, which does not meet people's needs
