Embodiment

Below in conjunction with the accompanying drawings, the utility model is described in detail.

In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing and implementation Example, the utility model is further elaborated.It should be appreciated that specific embodiment described herein is only explaining this Utility model, it is not used to limit the utility model.

Such as Fig. 1, a kind of 3D printer framework includes the pole of strip, nine poles in triangular prism shape combination arrangement so as to Make framework be in triangular prism shape, six poles form the base of triangular prism, and its excess-three pole forms the seamed edge of triangular prism, pole and It is fixedly connected between pole, can is dismountable or non-removable fixation, compared to using rectangular shape Framework, it is smaller as the space shared by the framework of 3D printer using the frame structure of triangular prism shape, so as in transportation In it is more convenient, save cost of transportation, also, installing space can be also saved when installing and using.

3D printer framework also includes fixed block, and fixed block is removably fixedly connected with pole, and fixed block forms prism Summit, that is, combine in triangular prism shape the pole of arrangement, the apex of triangular prism sets fixed block, and pole connects with fixed block Connect, so that whole frame structure is stable, is unlikely to loose, certain stress can be born, pole removably sets Put in fixed block, so as to dismantle, convenience in transport and collection.

Two poles are arranged in parallel to form a seamed edge of triangular prism, that is, two poles form a seamed edge side by side, Whole framework forms three seamed edges by six roots of sensation pole, in this way, structure is more stable, load ability further improves, more surely It is fixed reliable.

Such as Fig. 1 and Fig. 2, the horizontal stroke on a kind of 3D printer, including motor, shower nozzle, hott bed, said frame and fixed frame Bar, shower nozzle are arranged on cross bar in a manner of it can slide in X direction, and hott bed is arranged in a manner of it can be slided along Y-direction On framework, X is not parallel with Y, so, it is possible to allow shower nozzle to move along X and Y-direction, so as to complete two-dimentional air brushing action, structure letter Single, temperature is reliable.

Specifically, as shown in figure 1, there is two cross bars to be fixed on framework, the cross bar is made up of polished rod, on a pedestal Hole coordinates with polished rod, and so as to allow pedestal to be slided along polished rod, the both ends of a root skin band are fixedly connected with pedestal both ends respectively, the skin Band is around the driving wheel on pulley and motor, so as to which motor rotates, belt opposing frame motion, so as to be slided with moving base along polished rod Dynamic, the shower nozzle being arranged on pedestal also just slides with along polished rod；Similarly, both ends of the hott bed bottom also with another root skin band are fixed Connection, while pulley, motor and polished rod are equipped with, hott bed, which slides, to be set on polished rod so as to can only be slided along polished rod, in motor Driving lower belt motion is also moved so as to drive hott bed to be slided with respect to polished rod with regard to opposing showerhead.

The application 3D printer also includes screw mandrel, guide rod and fiber barrel, and fiber barrel is fixedly connected with cross bar, screw mandrel and fiber barrel Coordinate, cross bar is set on the guide bar in a manner of it can only be slided along Z-direction, and the axis of screw mandrel is parallel with Z, fixed on framework The motor being connected with screw mandrel is set, rotated with drive screw, Z, X and Y are not parallel to each other, and so, it is possible so that shower nozzle relative thermal Bed makes three-dimensional motion, simple in construction so as to complete 3D printing task, reliable and stable, specifically, screw mandrel surface is provided with spiral shell Line, fiber barrel are provided with the internal thread coordinated with screw mandrel, and the motor to match with pedestal is also fixedly installed with fiber barrel, to cause shower nozzle It can stablize and be run along Z-direction.

Hot plate is provided with least four hole, and bolt coordinates after successively passing through hole and framework with nut, and bullet is arranged with bolt Spring, both ends of the spring is respectively with hot plate and contact therewith and being in compressive state, so as to cause hot plate bearing capacity strong, and energy It is enough to keep balance, avoid influenceing 3D printing effect because of alignment error, it is possible to increase the installation accuracy of hot plate.

All made within spirit of the present utility model and principle all any modification, equivalent and improvement etc., all should be wrapped It is contained within the scope of protection of the utility model.
