Embodiment
Please consult Figure 1A and Figure 1B simultaneously, Figure 1A is fan of the present invention and fan checking device schematic representation, and Figure 1B is the fan checking device schematic representation of Figure 1A.Fan checking device 20 includes a bearing table 21, a vibration sensor 22, a plurality of fastener 23 and a plurality of pilums 24.Has a containing space 211 on the vibrating table 21, can allow a fan 10 can be installed in the containing space 211, and vibration sensor 22 is arranged at the bottom center place of bearing table 21 with respect to containing space 211, can measure a vibration values that is produced when fan 10 rotates.Pilum 24 is in order to linking with bearing table 21, and pilum 24 has more an elastomer 241, and elastomer 241 can be spring, silica gel, rubber or other equivalent and constitutes.Fastener 23 is arranged at two opposite sides of bearing table 21, in order to fan attachment 10.
See also Fig. 2, Fig. 2 separates schematic representation for the fastener segmentation of fan checking device.The fastener 23 of fan checking device 20 of the present invention can be subdivided into a thimble 231, an elastic element 232 and supports piece 233.When as installed, be bumped into earlier two opposite sides of bearing table 21 with thimble, elastic element and order to piece.At first, earlier the protuberance 231a with thimble 231 packs into towards containing space 211, makes the protuberance 231a of thimble 231 towards containing space 211, pack in regular turn again elastic element 232 with support piece 233.Piece 233 is supported in suitable more afterwards rotation, allow after the perforation 233a on the piece 233 can be corresponding mutually with the positioning hole 212 on the bearing table 21, pass positioning hole 212 and perforation 233a jointly with screw 25, rivet or other equivalents again, make fastener 23 be fixed on the bearing table 21.In the present embodiment, fastener 23 is with each screw up and down, yet is not limited to this, also can single screw.
Please consult Fig. 3 A and Fig. 3 B simultaneously, Fig. 3 A, Fig. 3 B are that fan is placed on the generalized section in the fan checking device.As desire with fan 10, when for example a serial fan is packed containing space 211 into, after only the framework 11 of fan 10 need being aligned in containing space 211 earlier, framework with fan 10 presses down again, because of the protuberance 231a of thimble 231 is the shape of circular arc streamline, the strength that originally pressed down can be changed into active force towards elastic element 232, after elastic element 232 is subjected to active force from thimble 231 directions, the framework 11 of fan 10 make elastic element 232 produce the deformation of compression, so can enter containing space 211.And when the screw on the framework 11 12 aligns with thimble 231, elastic element 232 can disengage the active force of part compression and thimble 231 is released, this moment, the protuberance 231a center of thimble 231 can partly enter in the screw 12, remaining part is then replaced the framework 11 of fan 10, make fan 10 can be fixed in the fan checking device 20, at least one side of framework 11 then is covered on the end face of bearing table 21.In addition, as need fan 10 is taken out to bearing table 21, only with hand is clamped the fan 10 and the application of force upwards, can fast easily quick-detach, and fastener 23 starts order is opposite with leading portion, then seldom gives unnecessary details at this.
When fan 10 rotated, the vibration meeting that is produced was sent to pilum 24 via bearing table 21, for the vibrational energy that allows fan 10 be produced is effectively transmitted, so bearing table 21 can phenolic resin, ABS resin or macromolecule material make.Thus, because the light-weighted result of bearing table 21 weight, the acceleration that is produced during vibration also amplifies thereupon, and has improved the induction precision of vibration sensor 22, shown in Figure 1A.In addition, because pilum 24 has the cause of elastomer 241, when receiving vibration, the suitable displacement that is produced of will vibrating is amplified, and so, more helps the situation of vibration sensor 22 detecting fans 10 vibrations.
In addition, please consult Figure 1B once more, in order to allow vibration sensor 22 can measure vibration values more accurately, so vibration sensor 22 is arranged at the bottom center place of bearing table 21, and at least two induction points that vibration sensor 22 is had then slightly adjust distance with fan 10 according to actual conditions.So, vibratory output can be finely tuned according to lever principle, makes the amplification vibration values that vibration sensor 22 can be suitable.So, induction point can respond to respectively fan 10 radially with axially on oscillating component.Again with induction point with after a vibration analyzer is electrically connected, the vibration values of being learnt is carried out numerical analysis, afterwards again with being electrically connected an of computer, with assay datumization and output.So, the operator can learn objectively by the numerical values recited of interpretation assay whether the fan 10 that is detected meets standard.
So, by the vibration sensor in the fan checking device 20 22, the user can detect the vibration values of radially each side of fan 10 easily, adds the characteristic of its conveniently fast disassembling, more helps judging fast defective products.
Yet, the advantage of fastener 23 of the present invention is also not only in this, because elastic element 232 for example is a spring, when elastic element 232 elasticity fail, as long as unclamp screw 25 or rivet, can make things convenient for and elasticity of substitution element 232 rapidly, can often protect fastener 23 and keep identical in conjunction with strength with the screw 12 of fan 10.So, more can guarantee the conformity of vibration sensor 22 detectings.
In addition, framework 11 shapes of also visual fan 10 do the containing space in the bearing table 21 211 to change.Therefore, no matter be square, circular, ellipse or rhombus, or even single rotor fan or serial fan, all can be suitable for fan checking device 20 of the present invention and measure.
In sum, fan checking device proposed by the invention can replace present feel check system, adopts mechanical sensing, with unified test condition and standard, not only accelerates correcting efficiency, more can promote the validity and the accuracy of assay.Fan checking device proposed by the invention again can quicken the speed of installing/dismounting fan, allows the assay datumization, makes things convenient for the proofer can be directly and rapidly by the numerical values recited of interpretation assay, can learn easily whether fan meets standard.
Though disclosed the present invention in conjunction with an above preferred embodiment; yet it is non-in order to limit the present invention; anyly be familiar with this operator; without departing from the spirit and scope of the present invention; can be used for a variety of modifications and variations, thus protection scope of the present invention should with enclose claim was defined is as the criterion.
