The invention is described in further detail below with reference to the figures and the specific embodiments. The step numbers in the following embodiments are provided only for convenience of illustration, the order between the steps is not limited at all, and the execution order of each step in the embodiments can be adapted according to the understanding of those skilled in the art. Furthermore, it should be noted that the embodiments and features of the embodiments in the present application may be arbitrarily combined with each other without conflict.
Referring to fig. 1, the embodiment of the utility model provides a trigeminy slider structure of 3D printer, including first slider 1, second slider 2, third slider 3, connecting plate 4 and optical axis 5, first slider 1 second slider 2 with third slider 3 sets gradually on the optical axis 5, connecting plate 4 is installed first slider 1 second slider 2 with on the third slider 3, connecting plate 4 with be equipped with spring 6 between the second slider 2.
In this embodiment, the inner walls of the first slider 1 and the third slider 3 at the two ends can be tightly attached to the outer wall of the optical axis 5 far from the connecting plate 4 by the elastic force applied by the spring 6, and the inner wall of the second slider 2 in the middle is tightly attached to the outer wall of the connecting plate 4, so that the radial play between the sliders and the optical axis 5 is eliminated, and the purpose of improving the precision is achieved.
In this embodiment, the spring 6 of the middle second slider 2 can provide pretightening force for the connecting plate 4, so that the three sliders are tightly connected with the optical axis 5 of the cylindrical straight line. Suppose that the gap caused by the abrasion of the first slider 1 and the third slider 3 at the two ends is d1, and the abrasion gap of the second slider 2 in the middle is d 2. With this wear, the gap between the slider and the optical axis 5 becomes large, resulting in a rapid decrease in machine accuracy. But the slide blocks are connected by elasticity, after abrasion, the slide blocks are tightly attached to the optical axis 5 of the cylindrical straight line because the elasticity of the spring 6 acts on the second slide block 2, and the operation is stable. Assuming that a gap d1 exists between the first slider 1 and the third slider 3 and a gap d2 exists between the second slider 2, the second slider 2 is moved closer to the side B of the optical axis 5 by the elastic force of the spring 6, the first slider 1 is moved closer to the side a of the linear optical axis 5 by the elastic force, and the three sliders are always closely attached to the wall of the cylindrical linear optical axis 5, so that the overall gap is eliminated and the accuracy of the triplex slider is kept stable.
