Problems solved by technology
Regarding the above-mentioned technical solution, the inventor found that there are at least some technical problems as follows: for example, during the leveling process, the powder raw material will enter the thread gap of the leveling device, causing the threaded hole screw to be stuck and the leveling device unusable. If the screw of a certain leveling device is stuck, the lowering platform of the forming cylinder needs to be replaced as a whole, resulting in high failure rate and high maintenance cost

The embodiment of the invention discloses a baseplate leveling device and powder bed additive manufacturing equipment. The baseplate leveling device includes a leveling mechanism and a base. The leveling mechanism includes a lateral leveling plate. The surface of the lateral leveling plate is connected with a columnar joint part. The columnar joint part is provided with an internal threaded hole.The surface of the base is provided with a ring sealing element and a screw rod. The screw rod is located in the ring sealing element. The external diameter of the columnar joint part is matched withthe internal diameter of the ring sealing element. The internal threaded hole of the columnar joint part and the screw rod are connected in a threaded mode and rotate to lift the height of the leveling mechanism. According to the baseplate leveling device and the powder bed additive manufacturing equipment, entrance of powder raw materials into a gap of a thread is avoided to a certain extent, andsituations that the threaded hole and the screw rod are clamped and cannot rotate during the use of the baseplate leveling device are reduced.
Description
[0001] This application claims the priority of the Chinese patent application submitted to the China Patent Office on December 27, 2018, the application number is 201811618853.6, and the application name is "a powder-proof bottom plate leveling device and powder bed additive manufacturing equipment". The entire contents are incorporated by reference in this application. technical field [0002] Embodiments of the present disclosure relate to the technical field of powder bed additive manufacturing equipment, and in particular to a bottom plate leveling device and powder bed additive manufacturing equipment. Background technique [0003] Additive manufacturing technology is a multidisciplinary system engineering technology. In the layer-by-layer selective deposition / sintering / melting additive manufacturing technology using powder as raw material, the melting quality of the initial layer is crucial to the smooth progress of subsequent processes. , and one of the key factors af...
