Embodiment
As shown in Figure 1, Multipoint synchronous docking rack pinion power assisting device of the present invention, it comprises: multiple connection tooth bar 1, multiple ball lock tooth bar 2, lower tooth wheel shaft 3, cog axle 4 and handle 5;
The tow sides connecting tooth bar 1 are all processed with tooth; Preferably, connect in certain length that tooth bar 1 can be set to front end and the reverse side the other end and be processed with tooth, other parts are anodontia, as long as this certain length can meet the demand engaged with wheel shaft for effect.
Lower tooth wheel shaft 3 and the parallel setting of axle 4 that cogs; The two ends connecting tooth bar 1 are engaged with lower tooth wheel shaft 3 and the axle 4 that cogs respectively, and the engaging position on same wheel shaft on adjacent connection tooth bar 1 is tow sides is arranged alternately; Multiple ball lock tooth bar 2 engages with lower tooth wheel shaft 3 and the axle 4 that cogs respectively, the ball engaged with lower tooth wheel shaft 3 and the axle 4 that cogs locks that tooth bar quantity is identical and spacing is equal, and tooth bar locked by the ball engaged with lower tooth wheel shaft 3 and the interlaced setting of position of tooth bar locked by the ball that engages with the axle 4 that cogs; One end of lower tooth wheel shaft 3 is fixedly connected with handle 5.
Further, the number connecting tooth bar 1 is 4, and the number of ball lock tooth bar 2 is 12.
Further, the gear of lower tooth wheel shaft 3 and the axle 4 that cogs is 7 grades with the accuracy of mesh being connected tooth bar 1.
Further, lower tooth wheel shaft 3 and the gear cogged on axle 4 adopt involute cylindrical straight gear bar, and profile of tooth is metric system, and modulus is 1, and the number of teeth is 19, and pressure angle is 20 degree, and material is 2Cr13, and gear surface hardness is HRC40 ~ 45.
Be 4 with the number of described connection tooth bar 1, the number of ball lock tooth bar 2 is 12 and is described for embodiment:
When handle rotates, drive lower tooth wheel shaft to rotate simultaneously, connect 4 of upper and lower gear shaft in addition and connect tooth bars 1 and realize rotating by their transmission can make to cog axle and lower tooth wheel shaft simultaneously.Connecting tooth bar is that interleaved adjacent is placed, and stressed transmission can be made so evenly reasonable.The rotation simultaneously of upper and lower gear shaft, make 12 balls engaged with it lock tooth bar 2 level of synchronization to move, thus realize high reliability and the highi degree of accuracy fast insert-pull of testing apparatus receiver installation module and test interface ABAP Adapter (being called for short ITA) installation module.By upper and lower 6 pairs of balls lock tooth bar, can realize docking side by side multiple UUT, as shown in Figure 2.Fig. 3 is shown in by this device rack and pinion drive mechanism principle sketch.
The present invention adopts this servomechanism of rack pinion, and subtracting force rate can reach 38.8, and what gear adopted is involute spur gear wheel, modulus is 1, and the number of teeth is 19, and pressure angle α is 20 °, profile of tooth is metric system, and material is 2Cr13, and surface treatment is modified HRC40 ~ 45.The accuracy of mesh of gear rack is 7 grades.Under this mechanism connects the traction of tooth bar 1 at 4, make the motion of 12 ball lock tooth bar 2 level of synchronization, thus realize the highi degree of accuracy fast insert-pull of receiver installation module and ITA installation module.4 connect tooth bar is that interleaved adjacent is placed, and makes stressed transmission evenly reasonable.Namely when overturning handle, driving lower tooth wheel shaft 3 to rotate, rotating by connecting the rack drives axle 4 that cogs, thus promoting the parallel motion of ball lock tooth bar 2.By upper and lower 6 pairs of balls lock tooth bar, can realize docking side by side multiple UUT.
Checking:
Applying moment T formula is (not considering system friction power consumption)
T＝f·L＝F·(d
1/2)
Wherein, F be module to relay, f be handle apply power, L is the arm of force of handle opposed gear rotating shaft, d
