Abstract
The invention provides a lead screw guide assembly and a three-dimensional (3D) printing apparatus, wherein the lead screw guide assembly includes a base, a first guiding member, a second guiding member and a lead screw guide. The first guiding member is disposed on the base and has a first channel extending along an axis. The second guiding member is movably coupled to the first guiding member along the axis. The lead screw guide is movably disposed on the base along the axis and located in the first channel. The lead screw guide is coupled to the second guiding member, so as to drive the second guiding member to move along the axis and hide in the first channel or protrude from the first channel.
Claims19
A lead screw guide assembly adaptable for a three-dimensional (3D) printing apparatus, comprising:
- a base;
- a first guiding member disposed on the base and having a first channel extending along an axis;
- a second guiding member movably coupled to the first guiding member along the axis;
- and
- a lead screw guide, being a single-piece member, movably disposed on the base along the axis and located in the first channel, the lead screw guide coupled to the second guiding member, so as to drive the second guiding member to move along the axis, and the driving of the second guide member simultaneously causing movement of the second guide member such that the second guiding member moves along with the lead screw guide to hide in the first channel or protrude from the first channel simultaneously wherein the lead screw guide has a pressing end and a guiding end opposite to each other, the pressing end is located at one side of the base relative to the second guiding member, and the guiding end is coupled to the second guiding member, when the lead screw guide moves along the axis and causes the pressing end to move away from the base, the lead screw guide drives the second guiding member via the guiding end to move along the axis and hide in the first channel, when the lead screw guide moves along the axis and causes the pressing end to move closer to the base, the lead screw guide drives the second guiding member via the guiding end to move along the axis and protrude from the first channel.
A three-dimensional (3D) printing apparatus, comprising:
- a printing stand;
- a lead screw guide assembly movably disposed above the printing stand, comprising:
- a base;
- a first guiding member disposed on the base and having a first channel extending along an axis;
- a second guiding member movably coupled to the first guiding member along the axis;
- and
- a lead screw guide, being a single-piece member, movably disposed on the base along the axis and located in the first channel, the lead screw guide coupled to the second guiding member, so as to drive the second guiding member to move along the axis, and the driving of the second guide member simultaneously causing movement of the second guide member such that the second guiding member moves along with the lead screw guide to hide in the first channel or protrude from the first channel simultaneously;
- and
- a printing unit connected to the lead screw guide assembly and corresponding to the lead screw guide.
