AI Technical Summary

Technical Problem

In multi-station metal 3D printing equipment, how can the piston plate be stably raised and lowered along the Z-axis without affecting the horizontal movement of the forming cylinder, so as to improve equipment utilization and printing efficiency?

Method used

The piston positioning and lifting mechanism includes a base plate, column, pallet, lifting column, drive mechanism, position detection unit and zero-point positioning system. The column guides and supports the pallet, and the grating ruler is used for real-time position detection to ensure the stable lifting and lowering of the piston plate. Combined with the drive mechanism and zero-point positioning system, it can achieve rapid clamping and positioning.

Benefits of technology

This achieves stable and precise lifting of the piston plate, improving the ease of use and printing efficiency of the equipment, reducing downtime, and increasing equipment utilization.

Abstract

The application relates to the technical field of metal additive manufacturing, in particular to a piston positioning and lifting mechanism for a multi-station metal 3D printer. The piston positioning and lifting mechanism comprises a bottom plate, two vertical columns arranged in parallel on the bottom plate, a supporting plate arranged between the two vertical columns, a jacking column arranged on the supporting plate, the jacking column being capable of extending into a forming cylinder to drive a piston plate to lift, a zero-point positioning system arranged at the end of the jacking column away from the supporting plate and used for dynamically connecting with the piston plate, a driving mechanism arranged on the bottom plate and used for driving the supporting plate to lift, and a position detection unit arranged on the bottom plate and used for detecting the lifting position of the supporting plate. The two vertical columns, the supporting plate, the jacking column and the zero-point positioning system are matched, the piston plate can be dynamically clamped and positioned together with the jacking column extending into the forming cylinder, the piston plate is driven to lift, the lifting stability of the piston plate is ensured, and the effect is achieved.
