3D printing lathe

Abstract

The invention discloses a 3D printing lathe. The 3D printing lathe comprises a main body, a processing table, an isolation device, an operation main shaft and a processing cavity, wherein the processing table is arranged on the main body; the processing table is arranged at the center of the bottom of the processing cavity, and the processing cavity is arranged in the main body in an inward concave mode; and the operation main shaft is arranged on the inner side surface panel of the processing cavity. The printing lathe has the beneficial effects that the relative position between a limiting plate and a rectangular frame is controlled, so that an isolation protection mechanism can be started or closed; a spring pushes an isolation plate to slide in an annular groove and to rise when a clamping block loses resistance, so that the effect of protecting a student is achieved, and the student is prevented from touching an internal working part; and based on the principle that opposite magnetisms attract each other, when movable rods are separated from notches of the annular grooves, the two movable rods attract and are close to enter the annular grooves due to the opposite magnetism, sothat the purpose of collecting the isolation plate is achieved, the safety during observation of the student is effectively guaranteed, and the non-obstacle property of the sight in linear observation is effectively guaranteed.

Description

technical field [0001] The invention relates to the field of lathes, in particular to a 3D printing lathe. Background technique [0002] Lathe knowledge is a compulsory course for students majoring in mechanics. In order to enable students to combine theory with practice and promote the absorption of teaching knowledge, the physical 3D printing lathe is introduced into the training course. The current 3D printing lathe has the following defects: [0003] Most of the existing lathe teaching tools exist in the form of models. When a real lathe is used as a teaching tool, students can intuitively know the internal structure and working principle of the lathe, and practical teaching will be adopted. , so that the teacher needs to focus on two purposes in the process of teaching. On the one hand, he pays attention to reminding students not to touch the internal devices, and on the other hand, he needs to carry out practical teaching, which has a large potential safety hazard.

[0003] Most of the existing lathe teaching tools exist in the form of models. When a real lathe is used as a teaching tool, students can intuitively know the internal structure and working principle of the lathe, and practical teaching will be adopted. , so that the teacher needs to focus on two purposes during the teaching process. On the one hand, he pays attention to reminding students not to touch the internal devices, and on the other hand, he needs to carry out practical teaching, which has a large potential safety hazard.
