A flexible planar rolling tool with measurable pressure

Abstract

A pressure measurable flexible planar rolling depression tool comprises a tool handle and a tool bit. The tool bit comprises a tool handle connecting block, a force sensor used for detecting rolling depression force on a machined surface, a sensor fixing base, a rolling wheel assembly and a flexible guiding assembly. The tool handle connecting block is located under the tool handle and fixedly connected with the tool handle. The sensor fixing base is located below the tool handle connecting block, and a gap is formed between the sensor fixing base and the tool handle connecting block. The flexible guiding assembly comprises guiding columns, springs and ball sleeves. Ball sleeve mounting grooves are formed in the upper end of a rolling wheel mounting base. The periphery of the sensor fixing base is provided with first through holes. The upper ends of the guiding columns are in interference fit with the tool handle connecting block. The lower end of each guiding column sequentially penetrates through the corresponding spring and the corresponding first through hole of the sensor fixing base to extend into the corresponding ball sleeve. The pressure measurable flexible planar rolling depression tool provided by the invention can detect the rolling depression force in real time, the surface quality of a machined workpiece is good, and a machine tool is prevented from shaking.

Description

technical field [0001] The invention relates to a plane rolling tool, in particular to a flexible plane rolling tool with measurable pressure. Background technique [0002] The rolling method refers to that under the action of the rolling tool, the external force induces strong plastic deformation on the surface of the metal material, and activates dislocations, stacking faults and other non-equilibrium defects inside the crystal through the plastic flow of the material near the surface, and through dislocation proliferation, twinning Crystallographic movements such as , slip, etc. will gradually cut the small-angle large grain boundaries into large-angle small grain boundaries, and realize the division and refinement of large surface grains into ultra-fine crystals or nanocrystals. Rolling processing is a kind of chip-free processing. It can not only achieve a high finish, but also improve the mechanical properties of the processed parts-surface hardness, fatigue performanc...
