Abstract
The utility model discloses a kind of silk material extrusion device of 3D printer, comprise motor, pedestal, elastic force handle and spring, described elastic force handle by handle chassis, bearing, bearing rotating shaft and bearing cap composition, described bearing rotating shaft is independent type steel axle, and described handle chassis and described bearing cap point are else provided with positioning step counterbore, the described bearing rotating shaft in common location.The bearing installation end of described bearing cap is fixed by snap on handle chassis.Below described handle chassis, discharge opening place is provided with the location counterbore to trunnion, and counterbore place is provided with cone boss.It is high that the utility model has bearing rigidity, long service life, and processing technology is simple, and advantage stably given accurately by silk material.
Description
Technical field
The utility model relates to the field of structural design of 3D printer, particularly relates to one 3D printer silk material extrusion device more reliably.
Background technology
Silk material is constantly delivered to printer head by silk material extrusion device thus is carried out print job by fusion sediment formula 3D printer.Silk material extrusion device plays fixation when advance and retreat material to silk material on the one hand, operationally realizes the feeding work to silk material on the other hand, and silk material extrusion device serves the positioning action to charging trunnion in its structure simultaneously.But, in its structure, have following defect at the extrusion device of the 3D printer seen on the market at present:
1. the shaft stiffness problem of bearing: in silk material extrusion device, silk material is pressed on drawing-inroller by bearing.And a kind of silk material extrusion device for 3D printer tape spring structure of patent (notification number: CN 203449611 U, file 1) and a kind of self adaptation silk material extrusion device (notification number: CN103552241 A for 3D printer of patent, file 2) the pivot design of location bearing be the part of elastic force handle, adopt the processing mode that integral molded plastic is shaping.But this rotating shaft can produce following problem: first, due to the small volume of handle, the global design mode of rotating shaft can increase difficulty of processing.Secondly, the material of locating shaft is similarly plastic material, in use, due to retreat at every turn material time, all need again by bearing clamping and positioning, and now adopt the rotating shaft of plastic material due to rigidity lower, can phenomenon of rupture be produced, reduce the service life of silk material extrusion device.
2. bearing cap fixation problem: handle cover mainly plays fixation to bearing rotating shaft in silk material extrusion device.File 1 adopts bolt to fix, and this locate mode is installed inconvenient, and the bearing cap of file 2 only adopts in the fixing mode of one end screw of elastic force handle, and this mode can make bearing in feeding process, produce the vibrations never jiggly phenomenon of generation feeding, affects print quality.
3. trunnion location counterbore problem: silk material extrusion device plays positioning action to trunnion by location counterbore, the mating surface of usual location counterbore and trunnion is plane, and the diameter of counterbore can slightly larger than trunnion external diameter, the discharge opening that this structure there will be silk material extrusion device can not aim at the silk material hole of trunnion, causes silk material not pass through smoothly.
Therefore, need a kind of new technical scheme to solve the problem.
Summary of the invention
The utility model, for the deficiencies in the prior art, provides one more reliable 3D printer silk material extrusion device, and it is high that this material extrusion device has bearing rigidity, long service life, and processing technology is simple, and advantage stably given accurately by silk material.
For achieving the above object, a kind of silk material extrusion device for 3D printer of the utility model can adopt following skill scheme:
Silk material extrusion device for 3D printer comprises a motor, pedestal, elastic force handle and spring;
Described elastic force handle by handle chassis, bearing, bearing rotating shaft and bearing cap composition;
Described bearing rotating shaft is independent type steel axle; Described handle chassis and described bearing cap point are else provided with positioning step counterbore, the described bearing rotating shaft in common location; Described bearing is installed in bearing rotating shaft;
The bearing installation end of described bearing cap is fixed by snap on handle chassis, and described elastic force handle, described pedestal are fixed on described motor by long spiro nail by the other end jointly, and described bearing cap is provided with buckle, and described handle chassis is provided with draw-in groove;
Be provided with discharge opening below described handle chassis, discharge opening place is provided with the location counterbore to trunnion, and counterbore is provided with cone boss, to be matched incompatible location trunnion by the conical socket of the one end with trunnion.
Compared with background technology, the beneficial effects of the utility model are: first, and described 3D printer adopts freestanding bearing rotating shaft, and manufacturing process is more simple.And the material of described bearing rotating shaft is steel, adds the service life of elastic force handle.Secondly, described bearing cap and handle chassis one end adopt screw fit, and one end adopts and is clasped, and not only making and installation is simple, and the bearing's looseness phenomenon preventing bearing cap one end to fix and cause, and makes the feeding of silk material extrusion device more steady.Finally, the location counterbore of handle chassis becomes cone boss structure from original platform structure, matches with the conical socket of one end of feeding trunnion, makes the discharge opening of pay-off aim at the silk material hole of trunnion, makes feeding more accurate.
