Fig. 2 be the utility model photocuring 3D printer leveling before schematic diagram;
Fig. 3 be the utility model photocuring 3D printer leveling after schematic diagram.
Specific implementation mode
With reference to the accompanying drawings and examples, the utility model is described in further detail.
As shown in Figure 1, the photocuring 3D printer of the utility model, including platform closing piece 1, cantilever 2, lead screw 3, printing are flat Platform 5 and levelling device 7.Wherein, levelling device 7 is built in platform closing piece 1, including:Set screw 71, steel ball closing piece 73, bullet Spring 72, steel ball 74 and steel ball locating piece 75.
Specifically, set screw 71 is connect by the screw hole 12 being arranged on platform closing piece 1 with steel ball closing piece 73.In this reality It applies in example, set screw 71 is base rice screw, can facilitate user's rotational fastener screw.Screw hole 12 is located at the top of platform closing piece 1, From top to bottom it is vertically arranged.
Spring 72 is sleeved on outside steel ball closing piece 73, steel ball closing piece 73 can be made to contact steel ball always by the tension of spring 72 74, and after the fixation of set screw 71, make steel ball closing piece 73 that can firmly fix steel ball 74 by the tension of spring 72, make it It is not rotatable.
The top of steel ball closing piece 73 is equipped with location hole and connects the set screw 71, bottom and 74 curved face contact of steel ball.Tool Body, the bottom surface of steel ball closing piece 73 and 74 curved face contact of steel ball, subsequent corrosion is consistent with the radius of steel ball 74.The location hole Diameter and the diameter of set screw 71 match.
Platform closing piece 1 is also provided with a through-hole under the screw hole 12, is slightly larger than the steel ball closing piece 73.In the present embodiment In, steel ball closing piece 73 is in boss-shaped, boss upper socket spring 72, make spring 72 be fixed on the through-hole and steel ball closing piece 73 it Between.
Steel ball locating piece 75 connects the peaceful stand lock block 1 of steel ball 74, so that steel ball 74 is fixed in platform closing piece 1 and rotatable. Specifically, steel ball locating piece 75, in annular shape, the mode that can be connected through a screw thread or be clamped is fixed on platform closing piece 1, wherein Between circular hole and 74 curved face contact of the steel ball.
Print platform 5 is fixedly connected with the steel ball 74 by platform fixed block 6, and three is integral, and steel ball 74 is described It is not rotatable in platform fixed block 6.Specifically, solid by screw between 74 three of print platform 5, platform fixed block 6 and steel ball Fixed connection.
2 one end connecting platform closing piece 1 of cantilever, other end connection wire rod 3.In the present embodiment, it is guarantee cantilever 2 and platform Closing piece 1 contacts fricton-tight, so that platform closing piece 1 is more solidly fixed on cantilever 2, one to be in contact with cantilever 2 in platform closing piece 1 Face is equipped with groove, is built-in with magnet 11.It is also built-in with magnet 21, and surrounding in the one side that cantilever 2 is in contact with platform closing piece 1 There is a complete cycle gradient, makes cantilever 2 that can seamlessly be inserted into the groove of platform closing piece 1.In addition, 1 top of platform closing piece is additionally provided with Hand the turn of the screw 4 is tentatively locked by the magnet of the two, is then tightened again after the groove that cantilever 2 is inserted into platform closing piece 1 Hand the turn of the screw 4 can be completely fixed.
Cantilever 2, which is connected through a screw thread, to be fixed on lead screw 3, can be moved up and down with the rotation of lead screw 3, to band Moving platform closing piece 1 moves up and down together with print platform 5.
Specifically, in use, first photocuring 3D printer is powered, lead screw 3 rotates, and drives print platform 5 to decline, instantly It drops to lead screw 3 when print platform 5 is bonded completely with printing plane 8 to stop operating, then locking positioning screw 71, withstands steel ball closing piece 73, so that steel ball 74 is fixed, to realize leveling.
Again as shown in Figure 2 and Figure 3, the signal respectively before the photocuring 3D printer leveling of the utility model and after leveling Figure.
Before leveling, inevitably there is certain angle of inclination between print platform 5 and printing plane 8, it is flat to be unsatisfactory for printing The condition parallel with printing plane 8 of platform 5, needs leveling print platform 5, to ensure printing precision.The present embodiment is just described in detail below Leveling process, first, photocuring 3D printer be powered after, lead screw 3 rotation under, entire print platform 5 is declined, printing is worked as When platform 5 is in contact with printing plane 8, inevitably there is certain angle between the two, not fitting completely, as shown in Figure 2.At this time because Levelling device 7 is not locked, and steel ball 74 can rotate in platform closing piece 1, due to print platform 5, platform fixed block 6 and steel ball 74 Be fixed as an entirety, so, with print platform 5 continue to decline and steel ball 74 by the reaction force of printing plane 8 and Rotation, the angle between print platform 5 and printing plane 8 just slowly reduce, until the two fitting completely, as shown in figure 3, at this time Screwed in place screw 71 makes print platform 5 also be locked therewith with stationary balls 74, and leveling since then is completed.
In conclusion the utility model makes print platform adjustable angle by the steel ball that can arbitrarily rotate, after leveling again Steel ball is positioned by set screw, print platform fixation is made to no longer rotate, it is easy to operate to realize the leveling of print platform Quick easy to get started, while printing precision is also improved, no matter how external working environment changes, and 3D printer is placed in horizontal plane Or inclined surface does not affect being normally carried out for printing.
It is above to lift preferred embodiment, the purpose of this utility model, technical solution and advantage have been carried out further specifically It is bright, it should be understood that the above is only the preferred embodiment of the utility model only, it is not new to limit this practicality Type, within the spirit and principle of the utility model, any modification, equivalent replacement, improvement and so on should be included in this Within the protection domain of utility model, the interest field that the utility model is advocated should be to be described in utility model application range Standard, not just the above examples.
