Description

Board combination with adjustable inter-board pitching angle

Technical Field

The utility model relates to a machine part field especially relates to an interplate every single move angle adjustable plate combination.

Background

The three-dimensional printing technology is characterized in that a computer three-dimensional design model is used as a blueprint, special materials such as metal powder, ceramic powder, plastics, cell tissues and the like are stacked layer by layer and bonded through a software layering dispersion and numerical control forming system in a laser beam mode, a hot melting nozzle mode and the like, and finally, an entity product is manufactured through superposition forming. Different from the traditional manufacturing industry in which the raw materials are shaped and cut in a machining mode such as a die and a turn-milling mode to finally produce finished products, the three-dimensional printing changes a three-dimensional entity into a plurality of two-dimensional planes, and the three-dimensional printing is used for producing the three-dimensional entity by processing the materials and superposing the materials layer by layer, so that the manufacturing complexity is greatly reduced. The digital manufacturing mode can generate various parts with complex shapes directly from computer graphic data without complex process, huge machine tool and much manpower, so that the production and the manufacturing can be extended to a wider production crowd.

At present, the forming mode of the three-dimensional printing technology is still evolving, and the used materials are various. Among various molding methods, the photocuring method is a well-established method. The light curing method is to use the principle that light curing materials are cured after being irradiated by ultraviolet light to perform material accumulation molding, and has the characteristics of high molding precision, good surface smoothness, high material utilization rate and the like.

A light-cured three-dimensional printing device is characterized in that an exposure system is arranged at the bottom of a storage tank, and a light beam pattern projected by the exposure system irradiates a layer of light-cured material at the bottom of the storage tank through a transparent bottom plate of the storage tank to be cured. The cured light-cured material will adhere to the bottom surface of the carrier. After each exposure system irradiates a light beam pattern to cure a layer of the light-cured material, the carrier plate slightly rises to lift the formed layer of the light-cured material, and the light-cured material which is still in a liquid state is allowed to flow into the space between the bottom of the storage tank and the cured material to wait for the next irradiation. And circulating the steps, and obtaining the three-dimensional workpiece formed by layer-by-layer accumulation. In order to avoid gradual curing of the light-cured material at the bottom of the storage tank under long-time light leakage irradiation, a scraper is used for scraping along the inner bottom surface of the storage tank after the carrier plate is pulled so as to remove the residual light-cured material. During operation of the scraper, there is a need to adjust the height of the scraper relative to the inner bottom surface, which is usually as fine as a few millimeters, which has the following disadvantages if adjusted by manually removing the scraper and reinstalling it:

(1) the dismantling and installation process is complicated;

(2) manual adjustment cannot be done to finely adjust the pitch;

(3) the plane where the scraper is positioned after the height is adjusted is not ensured to be parallel to the inner bottom surface, so that the two ends of the scraper have height difference.
