Description

Circular hot bed fixed knot of 3D printer constructs

Technical Field

The utility model relates to a 3D printer technical field especially relates to a circular hot bed fixed knot of 3D printer constructs.

Background

In order to realize the purpose of printing by a 3D printer, the vibration of a platform is reduced by mainly fixing a spring and an aluminum substrate in the current market printer, the height of the platform is adjusted by adjusting the compression amount of the spring, but the vibration caused by a high-speed printer cannot be counteracted by the spring but plays a role in reaction, namely, the vibration of the platform is more easily caused when the spring and the aluminum substrate are fixed by bolts during high-speed printing; this method can not counteract the vibration effect caused by high-speed motion, and has poor printing quality, low speed and high cost.

SUMMERY OF THE UTILITY MODEL

For overcoming prior art's defect, the utility model provides a circular hot bed fixed knot of 3D printer constructs, the effectual vibration problem that brings of 3D printer when high-speed motion of having solved.

The technical scheme for solving the technical problem is as follows: the utility model provides a circular hot bed fixed knot of 3D printer constructs, includes the fixed plate of a plurality of joints on the base, and fixed plate and base corner joint are fixed, and base top central authorities are equipped with hot bed, hot bed and fixed plate fixed connection.

Preferably, one end of the fixing plate is of a trapezoidal structure, and the other end of the fixing plate is of an inwards concave circular arc structure.

Preferably, the one end of fixed plate circular arc be equipped with the transition slope, the fixed plate circular arc end is equipped with the mounting groove.

Preferably, the hot bed is fixed on the mounting groove through a screw.

Preferably, the bottom surface of the fixing plate is provided with a plurality of arc-shaped edges, and the side edges of the arc-shaped edges are provided with a plurality of buckles matched with the base.

Preferably, the fixing plate is formed by die casting.

Preferably, the buckle is formed by injection molding.

Preferably, the hot bed is a circular thin plate.

The utility model discloses simple structure is ingenious, uses plastics buckle and fixed plate to have solved because the vibration that high-speed printing brought, can solve spring elasticity too good, makes the high-speed motion produce the problem of vibrations more easily, can reduce weight again.

Detailed Description

The following describes the embodiments of the present invention in further detail with reference to the accompanying drawings.

As can be known from the drawings 1 to 5, the circular hot bed fixing structure of the 3D printer comprises a plurality of fixing plates 2 which are connected with each other in a clamping mode on a base 1, the fixing plates 2 are connected with the corners of the base 1 in a clamping mode, a hot bed 3 is arranged in the center of the upper portion of the base 1, the hot bed 3 is fixedly connected with the fixing plates 2, the hot bed 3 is a circular thin plate, one end of each fixing plate 2 is of a trapezoidal structure, and the other end of each fixing plate 2 is of an inwards-concave circular arc-shaped structure matched with the corresponding hot bed 3.

When the utility model is used, the utility model,

base 1 installs on the 3D printer, then with

hot bed

3 and 2 fixed connection of fixed plate, then with 2 joints of fixed plate on base 1.

2 circular arc one ends of fixed plate are equipped with

transition slope

4, and 2 circular arc ends of fixed plate are equipped with mounting groove 5, and heat bed 3 is fixed on mounting groove 5 through the screw, and transition slope 4 makes the edge of heat bed 3 live by the parcel, does not expose outside, and protection heat bed 3 is not damaged.

2 bottom surfaces of fixed plate are equipped with a plurality of arriss 6 of strengthening, strengthen the side of arris 6 be equipped with a plurality ofly with base 1 complex buckle 7, buckle 7 adopts injection moulding, fixed plate 2 adopts die-casting. The fixed plate 2 is formed by die casting through a cast aluminum plate, and the reinforcing ribs 6 arranged on the back can improve the strength of the plate surface, keep the flatness of the fixed plate 2 and avoid bending deformation; the buckle 7 is formed by injection molding, is made of plastic on the outer surface, and is convenient to mount and fix with the base 1.

The utility model discloses a 2 appearances of fixed plate are customized according to the 3D printer, can be triangle-shaped, rectangle, and hexagon or other shapes can be on base 1 horizontal installation or perpendicular installation all can, as long as guarantee the plane degree of fixed plate 2, make it when printing at a high speed remain stable can.

The reinforcing ribs 6 arranged on the back side of the fixing plate 2 can offset the profit generated in the die-casting molding process, so that the fixing plate does not deform in the die-casting process, and the flatness of the fixing plate is ensured.

The hot bed 3 is fixedly connected with the fixing plate 2 through bolts and then is clamped on the base 1, so that the hot bed 3 is always integrated with the printer frame when being printed at a high speed, and the purpose of vibration isolation is realized.

Fixed plate 2 and buckle 7 all adopt the mould to process, guarantee its batch uniformity, reduce the processing degree of difficulty, reduction in production cost guarantees product quality.

The utility model discloses an it keeps apart with the die-casting forming technique to mould plastics, make hot bed 3 and printer frame main part damping to vibration is printed in effectual reduction, and the model that makes the printing is of high quality, and the layer line is few, and the success rate is high.

Compared with the prior art, the utility model, following beneficial effect has: the vibration is small during high-speed printing, so that the printing quality is improved; the production cost is low, the installation precision is high, and the control is easy; the utility model is used for the first time in the industry and is easy to be popularized.
