Detailed Description

In order to facilitate understanding of the invention, the invention will be described more fully hereinafter with reference to the accompanying drawings, in which several embodiments of the invention are shown, but which can be embodied in many different forms and are not limited to the embodiments described herein, but which are provided so as to render the disclosure of the invention more thorough and complete.

It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present; when an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present; the terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs; the terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention; as used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

Example 1

Referring to fig. 1 to 4, a 3D printer chassis according to this embodiment includes side plates 100, a triangular bottom plate 200 and a corner motor base 300, where the bottom plate 200 and the side plates 100 form a frame of a triangular prism structure, the side plates 100 are fixedly connected by the corner motor base 300, a servo motor 210 is disposed on the bottom plate 200, the servo motor 210 is fixed on the corner motor base 300, a plurality of components are disposed on the bottom plate 200, a threading connection block 110 is disposed on the side plate 100, a through hole 111 is disposed on the threading connection block 110, a corresponding through hole 111 is disposed on the side plate 100, if the chassis with this design is not adopted, the chassis with an integral structure is used, the chassis with an integral structure has poor anti-seismic performance, and after the servo motor 210 is installed, the vibration caused by asynchronous operation of the three servo motors 210 makes the entire chassis easily generate large vibration, which further results in poor printing accuracy, curb plate 100 of whole chassis adopts angle motor cabinet 300 to connect, and servo motor 210 installs on angle motor cabinet 300, and the vibrations that servo motor 210 produced are absorbed respectively by angle motor cabinet 300 and are alleviated, and overall stability is high for the vibrations of servo motor 210 when the operation fall to minimumly, carry out the threading cooperation in the threading connecting block 110 of curb plate 100, improved the security and the stability of whole chassis.

Through-hole 310 that runs through from top to bottom is equipped with on the angle motor cabinet 300 of this embodiment, servo motor 210's output shaft passes angle motor cabinet 300 and is located through-hole 310, if do not establish through-hole 310 on the angle motor cabinet 300, servo motor 210's output shaft is direct to be connected in angle motor cabinet 300 top with the belt, angle motor cabinet 300 is poor to servo motor 210's bradyseism effect, lead to printing the precision poor, and the structure of this design has been adopted, angle motor cabinet 300 protects the junction of servo motor 210 and belt, the noise that stable angle motor cabinet 300's hole structure also reduced servo motor 210 and belt friction production simultaneously.

The both sides of the angle motor cabinet 300 of this embodiment are equipped with draw-in groove 320, and the one end and the draw-in groove 320 joint of curb plate 100 design draw-in groove 320 and carry out the joint, have improved the stability and the firmness of connecting, if direct face contact connects, and it is not hard up to take place easily for a long time to use, leads to printing the effect poor, and the precision is low.

The central plane a of servo motor 210 of this embodiment is coplanar with the plane of symmetry b of the frame of triangle column structure, if not adopt this design, the rocking that servo motor 210's vibrations brought is different at this servo motor 210's both sides dynamics, because whole is three servo motor 210 operation work, consequently servo motor 210 brings the vibration intensity department difference for bottom plate 200, lead to this chassis can take place slight vibrations at work, further lead to printing effect poor, and the structure of this design has been adopted, the area of servo motor 210 both sides is the same, the pressure of whole vibrations is the same in both sides, overall strength keeps the symmetry, be difficult to form vibrations disorder, stability is high.

The wiring harness slot 220 is formed in the bottom plate 200 of the embodiment, and due to the design, connecting lines on the bottom plate 200 are not prone to confusion, and maintenance and replacement of parts are facilitated.

The above-mentioned embodiments only express a certain implementation manner of the present invention, and the description thereof is specific and detailed, but not construed as limiting the scope of the present invention; it should be noted that, for those skilled in the art, without departing from the concept of the present invention, several variations and modifications can be made, which all fall within the protection scope of the present invention; therefore, the protection scope of the present invention should be subject to the appended claims.
