Detailed description of the invention
As it is shown in figure 1, the Multipoint synchronous docking rack pinion power assisting device of the present invention, comprising: many
Individual connection tooth bar 1, multiple ball lock tooth bar 2, lower tooth wheel shaft 3, gear axle 4 and handle 5；
The tow sides connecting tooth bar 1 are all machined with tooth；Effect is it is also preferred that the left connect tooth bar 1 and could be arranged to
Being machined with tooth in the certain length of front end and the reverse side other end, other parts are anodontia, if this fixed length
Degree disclosure satisfy that the demand engaged with wheel shaft.
Lower tooth wheel shaft 3 and gear axle 4 are arranged parallel；Connect tooth bar 1 two ends respectively with lower tooth wheel shaft 3
Engage with gear axle 4, and the position of engagement on adjacent connection tooth bar 1 is tow sides on same wheel shaft
It is arranged alternately；Multiple balls lock tooth bar 2 engages with lower tooth wheel shaft 3 and gear axle 4, respectively with lower tooth wheel shaft 3
Identical and spacing is equal with the ball lock tooth bar quantity of gear axle 4 engagement, ball engage with lower tooth wheel shaft 3 is locked
The interlaced setting of position of tooth bar locked by tooth bar and the ball engaged with gear axle 4；Lower tooth wheel shaft 3
One end is fixing with handle 5 to be connected.
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 gear axle 4 is 7 with the accuracy of mesh being connected tooth bar 1
Level.
Further, the gear on lower tooth wheel shaft 3 and gear axle 4 uses 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, gear surface
Hardness is HRC40～45.
Being 4 with the number of described connection tooth bar 1, the number of ball lock tooth bar 2 is 12 and carries out for embodiment
Illustrate:
When handle rotates, drive lower tooth wheel shaft to rotate simultaneously, additionally connect 4 companies of upper and lower gear shaft
Connecing tooth bar 1 can make gear axle and lower tooth wheel shaft realize rotating by their transmission simultaneously.Connecting tooth bar is
Interleaved adjacent is placed, and the transmission that so can make stress is the most reasonable.The rotation simultaneously of upper and lower gear shaft,
Make 12 the ball lock tooth bar 2 level of synchronization motions engaged, thus realize testing equipment receiver and mould is installed
High reliability and the high accuracy fast insert-pull of module installed by block and test interface adapter (being called for short ITA).Pass through
Upper and lower 6 pairs of balls lock tooth bar, can realize docking multiple UUT side by side, as shown in Figure 2.This device gear
