Namely on conducting metal shell fragment, the first contact site 11 conducts electricity with the parallel site portion be close to of the first conductive layer 21, the site portion that on conducting metal shell fragment, the second contact site 12 is touched with the first clamping part 32 under external force conducts electricity, and the position of these two partially conductives is communicated with by the position of conducting metal shell fragment 1 upper part conduction.
In conductive holding main body, the first main part 31 conducts electricity with the parallel site portion be close to of the second conductive layer 23, the site portion that first clamping part 32 is touched with the second contact site 12 under external force conducts electricity, and the position of these two partially conductives is communicated with by the position of conductive holding main body 3 upper part conduction.
Above-mentioned partially conductive position can make by using metal material or realizes by pasting the modes such as conductive layer.
Described FPC 2 is not provided with extension stub-out, but directly draws the output of holding wire implementation platform calibrating signal.
In the present embodiment 2, the end face of described print platform is circular, described 3D printer platform alignment device comprises more than 3 platform alignment folders, the uniform edge being clamped in print platform end face of circumference, realizes the clamping of the workbench fixed mount 8 of workmanship plate 9 and 3D printer and the calibration function of 3D print platform.
For embodiment 1, the course of work and the principle of 3D printer platform alignment device provided by the invention are: after on holding shrapnel 4, the second clamping part 42 is fixed on the bottom surface of workbench fixed mount 8, be rotated through the conductive holding main body 3 that bearing pin 6 is connected with holding shrapnel 4, first clamping part 32 of conductive holding main body 3 is fitted the end face of workmanship plate 9 under external force turning effort, in rotary course, the first clamping part 32 1 power upwards given by workmanship plate 9, thus make the first clamping part 32 by bearing pin 6 to one of holding shrapnel 4 power upwards, the bottom surface that simultaneously holding shrapnel 4 is subject to workbench fixed mount 8 gives holding shrapnel 4 one downward power, under the comprehensive function of these two external force, there is certain elastic deformation in holding shrapnel, according to elastic deformation principle, holding shrapnel can form reaction force to the parts it being applied to external force, namely one, the bottom surface power upwards of workbench fixed mount 8 is given, and by power that bearing pin 6 and the first clamping part 32 give the end face one of workmanship plate 9 downward, a chucking power is defined between first clamping part 32 of now parallel conductive holding main body and the second clamping part 42 of holding shrapnel, thus firmly achieve this position workmanship plate 9 and workbench fixed mount 8 grip effect, what both achieved this position print platform grips effect.
When carrying out 3D print platform calibration operation, 3D printing head is displaced to platform alignment folder top and downwards to the external force that second contact site 12 1 of conducting metal shell fragment is downward, the second contact site 12 is touched with the first clamping part 32 of conductive holding main body 3 under external force; Say from circuit, in the moment of touching, the second contact site 12 is communicated with the first clamping part 32; Thus make the first contact site 11 of being communicated with the second contact site 12, and the first main part 31 be communicated with the first clamping part 32 is communicated with; And then make first conductive layer 21 be close to parallel with the first contact site 11, and second conductive layer 23 be close to parallel with the first main part 31 is communicated with, and namely makes short circuit between the first conductive layer 21 and the second conductive layer 23; When 3D printing head lift no longer apply external force to the second contact site 12 of conducting metal shell fragment time, second contact site 12 is upspring and is recovered and leave gap with the first clamping part 32, say from circuit, second contact site 12 and the first clamping part 32 disconnect, as above principle, finally makes separated formation open circuit (or open circuit) of the first conductive layer 21 and the second conductive layer 23.So, by the extension stub-out of the first conductive layer 21 and the second conductive layer 23 or the holding wire of directly drawing, the output (as measured the methods such as the change of electric current between two conductive layers or resistance) of the platform alignment signal of existing clamp and calibration site can be realized; Certainly, by according to actual conditions need arrange that multiple platform alignment is pressed from both sides, clamping and the calibration function of 3D print platform diverse location can be realized.Thus while in the top and bottom achieving retaining part being the firm clamping action of plane-parallel 3D print job platform, achieve the accurate output of platform alignment signal, save the calibration accessory that former need configure in addition, and saved effective 3D print space of the preciousness that former calibration accessory takies, there is higher practicality and promotional value.
Above implementation column does not form restriction to the present invention, and relevant staff is in the scope not departing from the technology of the present invention thought, and the various change carried out and amendment, all drop in protection scope of the present invention.
