Example Embodiment

[0016] The driving wheel 1, the idler 4, the tensioning mechanism 5, and the grinding and polishing pressure control mechanism 6 are installed on the tool plate 2. The servo motor 9 is connected to the tool plate 2 through the motor support 8, and the driving wheel 1 is connected to the servo motor 9 to contact The wheel 7 adopts a structure in which rubber material is pasted on the main surface of the metal hub. The sanding belt 3 is wound around the driving wheel 1, the idler 4 and the contact wheel 7, and the tensioning mechanism 5 is connected to the sanding belt 3 in tension;

[0017] The structure of the tensioning mechanism is that the tensioning arm shaft 501 is mounted on the tool plate 2 through a bearing, the tensioning arm 505 is fixedly connected to the tensioning arm shaft 501, and the spring 503 is installed on the tool plate 2 through a pin 504. The tension arm 505 takes the tension arm shaft 501 as a fulcrum, one end is installed with a tension wheel 502, and the ...

Abstract

The invention relates to a pressure controllable abrasive belt tool system for grinding and polishing blades, and belongs to the tools for grinding and polishing blades. A driving wheel, an idle wheel, a tensioning mechanism and a grinding and polishing pressure control mechanism are mounted on a tool board, a servo motor is connected with the tool board through a motor stand, the driving wheel is connected with the servo motor, a contact wheel is provided with a structure with rubber materials pasted on the surface of a metal hub body, an abrasive belt is in wrapping connection with the outside of the driving wheel, the idle wheel and the contact wheel, and the tensioning mechanism is connected with the abrasive belt in a tensioning manner. The pressure controllable abrasive belt tool system has the advantages that the structure is novel, the problem of coupling of grinding and polishing pressure and normal indentation amount in the grinding and polishing process is solved, force decoupling in the grinding and polishing process is realized, the tool system for force decoupling is provided for automatic grinding and polishing operation of blade profiles, grinding and polishing pressure can be effectively controlled when the blades are grinded and polished by the abrasive belt, curved surfaces of the blades are more uniformly grinded and polished, and machining quality is higher.

Description

technical field [0001] The invention belongs to the field of mechanical manufacturing, and in particular relates to a tool for blade grinding and polishing. Background technique [0002] Blades are typical key parts of turbomachinery equipment such as steam turbines, water turbines, and aero-engines, with thousands of blades and tens of thousands of blades. Blades work in high temperature, high pressure, and strong corrosive environments for a long time, and are subjected to alternating loads, requiring them to have good mechanical properties, thermal deformation resistance, and corrosion resistance. Any design and manufacturing defects may lead to reduced work efficiency , and even destroy the overall unit, resulting in significant economic losses. Blade parts have complex shapes, high quality requirements, and difficult processing. [0003] At present, the grinding and polishing of blades in my country is mainly done by hand, which has high labor intensity, low efficienc...
