Fulcrum-limiting two-stage floating type flexible retention mechanism for grinding equipment

Abstract

The invention relates to a fulcrum-limiting two-stage floating type flexible retention mechanism for grinding equipment. The mechanism comprises a driving center plate, a second driving center plate and a grinding plate which are assembled together and all integrally of a three-jaw structure, grinding heads are fixed at the bottom of the grinding plate, and a floating gap is formed between the grinding plate and each grinding head. The mechanism is characterized by further comprising first elastic elements arranged in the floating gaps and second elastic elements arranged between the first driving center plate and the second driving center plate, a spherical pair mechanism is arranged between the grinding plate and each grinding head, and the first elastic elements are matched with the spherical pair mechanisms to form first-stage flexible floatation. The second elastic elements are matched with the first driving center plate and the second driving center plate to form a second-stage flexible floatation. The mechanism has the advantages that the grinding heads are enabled to be in full contact with rugged surfaces constantly, situations of grinding stress non-uniformity of a tool, eccentric wear of the tool, poor cutting effect and the like are eliminated or reduced effectively, and flatness and smooth finish of ground surfaces are improved.

Description

technical field [0001] The invention relates to the technical field of grinding equipment accessories, in particular to a two-stage floating flexible holding mechanism for a fulcrum limit for grinding equipment. Background technique [0002] During the construction process of processing stone slabs or roads and building floors, it is necessary to polish the stone slabs, road surfaces, and floor surfaces to be smooth and flat. To make the surface of slabs, floors, and roads smooth, it is mainly to use grinding or polishing equipment to obtain a flat, clean, and smooth surface by cutting, milling, grinding, polishing, or crushing and cleaning the surface to be processed. . [0003] The current grinding equipment includes a power device. A power output mechanism is installed on the output shaft of the power device. There are multiple power output sub-shafts under the power output mechanism. Each power output sub-shaft is connected to a piece of power output through a rubber co...

Problems solved by technology

[0006] However, the equipment in the prior art outputs the power to the tool through webs or rubber elements, wherein the tool with the elastic coupling can only swing around the rotation axis of the fixed point to deal with large areas of slope in the concrete ground, while for small The ground grinding head with uneven area is often not easy to reach, so there will be uneven force on the tool grinding, partial grinding of the tool, poor grinding and polishing effect, etc.

The elasticity provided by the web or rubber elements alone is difficult to meet the degree of freedom and flexibility required for uneven ground, making grinding and polishing and its results difficult to predict and control, resulting in reduced surface quality
