One-step working platform limit adjustment device

Abstract

The invention discloses a one-step type working platform limiting and regulating device. The one-step type working platform limiting and regulating device comprises a working platform fixing frame, a transition block, a hand wheel and a base with a mounting base, wherein the bottom surface of the working platform fixing frame is of an oval spherical crown convex surface; the top surface of the mounting surface is of an oval spherical crown concave surface adaptive to the top surface, and the bottom surface of the mounting surface is an oval spherical crown convex surface; the top surface of the transition block is an oval spherical crown concave surface adaptive to the bottom surface of the mounting base; the hand wheel comprises a rod part and an end cover; a first through hole is formed in the transition block, a second through hole is formed in the mounting base, and a third through hole is formed in the working platform fixing frame; the rod part of the hand wheel passes through the first through hole and the second through hole and then is matched with the third through hole; the hole diameter of the second through hole is larger than the diameter of the part, positioned in the second through hole, of the rod part, so that the oval spherical crown convex surface on the bottom surface of the working platform fixing frame can be mounted on the oval spherical crown concave surface of the mounting base in a limiting and rotating mode. According to the one-step type working platform limiting and regulating device disclosed by the invention, the limiting regulation of the working platform in the X-axis direction and the Y-axis direction can be precisely realized, multi-position regulation and direction regulating multidirectional interferences are reduced, the complexity and variety of the platform direction regulation are reduced, and the one-step type working platform limiting and regulating device is efficient and convenient.

Description

technical field [0001] The invention relates to a platform adjustment device, in particular to a platform adjustment device on a 3D printer. Background technique [0002] Existing 3D printers, especially the printing platforms of desktop-level 3D printers, are fixed on the working platform fixing frame inside the 3D printer to form a 3D printing platform by fixing a removable working platform such as a workboard. The 3D printing platform needs to be calibrated before and during work (usually to a horizontal position) to correct the offset of the working platform during installation or working vibration. If there is a problem, the orientation of the printing platform needs to be adjusted. [0003] The azimuth adjustment of the working platform in the existing 3D printers and other machines is realized by screwing the screws around the printing platform that play a role in fixing and adjusting. This adjustment can only achieve fine adjustments, and it is easy to have multiple ...

Problems solved by technology

If it is found that a corner position is low after calibration, the printing platform needs to be adjusted. After the adjustment screw corresponding to the corner is screwed, in order to keep the printing platform in good balance, the adjustment screws corresponding to the other corners that are affected or even all All the adjustment screws need to be adjusted precisely to complete the adjustment function of the printing platform, otherwise the plane of the printing platform cannot be adjusted to the required horizontal position, and may cause the printing platform to be uneven, warped, and have no support in some areas or excessive support However, due to the mutual influence between the adjustment screws, it is difficult to adjust each adjustment screw one by one to make it more accurate for each adjustment. This adjustment is relatively rough and cumbersome, which seriously affects the accuracy of 3D printing. and stability
