Fixture for high-frequency brazing of cemented carbide cutter head and structural steel handle

Abstract

The invention discloses a clamp for high-frequency brazing between a hard alloy tool bit and a structural steel knife handle. The clamp comprises a walking type base, a stand column, a knife handle installation frame, a knife handle installing frame lifting driving mechanism, a knife handle clamping mechanism, a tool bit installing frame and a tool bit clamping and screwdown mechanism; the stand column is vertically and fixedly installed on the walking type base, the tool bit installing frame is fixedly installed on a column body at the top end of the stand column, and the tool bit clamping and screwdown mechanism is arranged on the tool bit installing frame; and the knife handle installing frame is installed on the position, at the middle lower part of the stand column, of the column body, the knife handle installing frame is connected with the stand column through the knife handle installing frame lifting driving mechanism, the knife handle clamping mechanism is arranged on the knifehandle installing frame, and a handle installing frame locating and locking mechanism is further installed on the knife handle installing frame. According to the clamp, the problems that in the priorart, the quality of a knife is easy to be influenced by human factors and the brazing machining efficiency is low after brazing are solved, the clamp greatly improves the brazing processing efficiency, the quality of the knife after the brazing is effectively guaranteed, and the clamp is low in manufacturing cost.

Description

technical field [0001] The invention relates to a tooling for high-frequency brazing, in particular to a clamp for high-frequency brazing of a hard alloy cutter head and a structural steel handle. Background technique [0002] As one of the important components of the aero-engine, the turbine disk is mainly made of high-temperature alloy or powder metallurgy, and the assembly holes need to be processed in groups on the turbine disk. When the assembly holes are processed in groups, it is necessary to process the tool with Excellent cutting performance and high toughness, the processing tools that can meet this requirement at present are tools made of carbide cutter heads and structural steel handles, while carbide cutter heads and structural steel handles need to pass Connected by high frequency brazing. [0003] At present, the brazing connection of the cemented carbide cutter head and the structural steel handle is mainly done by hand, resulting in that the quality of the ...

AI Technical Summary

Problems solved by technology

[0003] At present, the brazing connection between the cemented carbide cutter head and the structural steel handle is mainly done by hand, which leads to the quality of the brazed tool being easily affected by human factors, and the brazing process efficiency is relatively low, which is difficult to meet the actual production needs

If you purchase special brazing equipment, its expensive price becomes the primary restrictive factor
