Below with reference to 3,4 and 5, it is that floating governor motion carries out the work process schematic diagram adjusting that floats, with reference to figure
The operation principle and inventive method of the regulation of floating of detection means is described in further detail:
The state of no position deviation: detection means is when using, if keeper 3 and adapter 9 are entirely without position deviation,
Because the location division 31 of keeper 3 is higher than probe 2, so location division 31 can take the lead in inserting the recess 91 of adapter 9, continue close
Afterwards, after location division 31 and recess 91 bottom offset, keeper 3 is promoted to move downward elasticity of compression assembly 34.Probe 2 moves closer to
And finally contacting and be pressed together on the solder joint 93 of adapter 9, the solder joint 93 of last adapter 9, probe 2, switching pin 5, pcb are corresponding
Contact is sequentially connected conducting.Due to location division 31 positioning action mutual with recess 91, probe 2 is automatically and a pair of solder joint 93 1
Accurate.In addition, the solder joint 93 of adapter 9 is applied with downward power to probe 2, make probe 2 and switching pin 5 contact tightly, and then
Also so that switching pin 5 contact corresponding with pcb plate 7 is in close contact, improve the conduction of probe 2 and corresponding contact on pcb plate 7
Energy.
The state of existence position deviation: due to the tolerance of existence position error or parts, in practical work process or many
Or there is certain position deviation less, lead to location division 31 cannot smoothly enter recess 91, or probe 2 cannot be with adapter 9
Solder joint be accurately aligned.The present invention is due to devising floating governor motion in detection means, it is possible to achieve keeper 3, probe 2 phase
Automatically float regulation to adapter 9.With reference to shown in 3,4 and 5, floating governor motion is realized floating when adjusting, by positioning
The longitudinal stroke of part 3 and infeed stroke are realizing.Wherein keeper 3 longitudinal stroke includes first longitudinal direction stroke: keeper 3 and company
Connect device 9 wall portion 92 offset after, the pressure of the wall portion 92 of adapter 9 makes keeper 3 gradually toward the internal longitudinal contraction of fixed station 4,
Elasticity of compression assembly 34；Because the inclined-plane 321 of the installation portion 32 of keeper 3 gradually leaves narrow section of the second through hole 42, installation portion
32 are gradually increased with the gap a of the hole wall of the second through hole 42.The infeed stroke of keeper 3 is released and makes infeed stroke also gradually
Increase.At this moment, keeper 3 can gradually to orientation or revise direction displacement (in the state of as shown in Figure 3, orientation
Can be understood as level direction to the right), and in infeed stroke, keeper 3 drives erecting bed 1 in the lateral displacement of fixed station 4
And the probe 2 on erecting bed 1 follows keeper 3 lateral displacement simultaneously, automatic aligning is put deviation and is corrected/revises.
With reference to Fig. 3, keeper 3 longitudinal stroke also includes second longitudinal direction stroke: after first longitudinal direction stroke terminates, due to positioning
When part 3 is offseted with the wall portion 92 of adapter 9, corresponding position deviation exceeds the floating range of accommodation of floating governor motion, so
Under wall portion 92 impetus of adapter 9, keeper 3 continues the warning up on keeper 3 for the longitudinal contraction toward inside fixed station 4
Pin 33 and the corresponding contact of warning circuit, illustrate that keeper 3 has done the row stroke of maximum magnitude, but float and adjust still
Failure, at this moment alarm needle 33 triggering is reported to the police, it is to avoid compress further, damages probe 2 or adapter 9.
With reference to Figure 4 and 5, keeper 3 longitudinal stroke also includes the 3rd longitudinal stroke: through the first longitudinal direction row of keeper 3
After the preliminary floating of journey and infeed stroke is adjusted, the wall portion 92 of adapter 9 is smoothly left in the location division 31 of keeper 3, smoothly enters
Enter the recess 91 of adapter 9, keeper 3 and adapter 9 continue near after, the bottom of recess 91 of adapter 9 and keeper 3 phase
Make keeper 3 toward the internal longitudinal contraction of fixed station 4 after supporting and then close infeed stroke and make the solder joint of probe 2 and adapter 9
91 corresponding contacts and no longer transverse shifting.With reference to Fig. 5, during the 3rd longitudinal stroke, connection is smoothly left in location division 31
