Delta 3d printer upper support structure

Abstract

The invention discloses an upper support structure for delta 3D printers, which comprises an upper supporting seat, wherein the upper supporting seat is connected with a support pillar, the middle of the upper end face of the upper supporting seat is provided with a wire feed structure, the upper supporting seat is provided with a vertically-arranged upper wire threading hole, the upper part of the upper supporting seat is connected with a printed material bracket, the upper part of the support pillar is provided with a horizontal support block, the horizontal support block is provided with a right-angle type third aluminum profile connector, the third aluminum profile connector is fixedly connected with the horizontal support block, a fixed pin is arranged in a connecting hole of the third aluminum profile connector, the other end of the fixed pin is provided with a bearing, a bearing outer ring is provided with a driving belt, the driving belt is connected with a slide block, the slide block is in sliding fit with a slide rail on the support pillar, the slide block is connected with a ball cardan joint, and the ball cardan joint is connected with a printer head connecting rod. The support structure disclosed by the invention is compact in structure; and the main connecting components are of a profile structures, so that the support structure is high in strength and good in rigidity, and the installation and disassembling of components are convenient, and therefore, the support structure is widely applicable to small-sized 3D printers.

Description

technical field [0001] The invention relates to the technical field of 3D printers, in particular to an upper support structure of a delta 3D printer. Background technique [0002] In the prior art, the connection structure between the upper support structure of the 3D printer and the vertical column mostly adopts metal or plastic components. High strength, especially plastic components, due to low rigidity and strength, complex structure and easy deformation, after being subjected to frequent stress and vibration, it is easy to loosen and deform, and it is easy to age and malfunction after a long time. The vertical movement mechanism is connected, and the movement resistance after deformation is large, which increases the friction between the kinematic pairs, and also affects the accuracy of the movement of the vertical movement mechanism, thereby affecting the quality of the printed product, and even causing waste products, which increases the production cost. .
