Description

Technical Field

[0001] This application relates to the field of 3D printer technology, and in particular to a leveling stand for a 3D printer. Background Technology

[0002] In traditional manufacturing, product manufacturing relies on subtractive manufacturing or equal-material manufacturing processes. Subtractive manufacturing, such as machining, removes excess material from raw materials through cutting and grinding to obtain the desired shape. This not only results in significant waste of raw materials but also presents challenges for complex components, leading to high processing difficulty, costs, and inefficiency. With continuous technological advancements, 3D printing technology, also known as additive manufacturing, has emerged. Unlike traditional manufacturing processes, 3D printing constructs objects by layering materials based on three-dimensional model data. This unique manufacturing method overcomes the limitations of traditional manufacturing processes in terms of structural complexity, easily creating products with complex internal structures and personalized customization. Currently, 3D printing equipment is widely used in numerous fields, including aerospace, automotive manufacturing, medical, construction, and education.

[0003] Traditional base leveling typically involves only initial calibration at the factory. While this calibration ensures initial stability, unavoidable vibrations and bumps during transport can easily disrupt the base's balance. Over time, wear and aging can also cause the base to gradually become unbalanced. For users, the lack of professional leveling equipment is a major problem. Once the base becomes unbalanced, they lack effective correction methods and cannot independently perform precise leveling. Existing 3D printing equipment with built-in leveling mechanisms mostly uses manual leveling, requiring two workers to work together: one to operate the leveling ruler and the other to adjust the base bolts. This process is not only time-consuming and labor-intensive but also demands a high level of skill and coordination from the workers, significantly impacting work efficiency and leveling results.

[0015] Preferably, it also includes a positioning buckle consisting of positioning protrusions and positioning recesses engaging, with the positioning protrusions located on the back of the angle plate and the flipping component, and the positioning recesses located at the bottom of the telescopic plate.

[0016] Based on the above technical solutions, the locking key is a common locking structure in telescopic structures. It is used to lock the length between the corner plate and the sliding plate, as well as the telescopic length of the telescopic plate.

[0017] Preferably, the sliding plate is threaded with an adjustment knob, and the bottom end of the adjustment knob is coaxially connected to the leveling measuring head.
