Detailed description of the invention
The embodiment combined in accompanying drawing is further described by the present invention below:
As shown in Fig. 1 ~ 3, the invention mainly comprises testing base 1, testing base 1 is fixed testing and debugging seat 2, testing and debugging seat 2 is bolted lower testing and debugging block 3, lower testing and debugging block 3 is in clamping connection testing and debugging block 4 by testing and debugging screw 8.
Being bolted arm swing support 5 on upper testing and debugging block 4, before and after arm swing support 5, lateral symmetry position is rotationally connected a swing arm 6 by arm shaft 11 respectively, connects swing arm extension spring 7 between two swing arm 6 lower ends.It is provided with arm shaft bearing 12 between arm shaft 11 and swing arm 6, outside arm shaft bearing 12, is provided with the E type clasp 13 preventing arm shaft bearing 12 from coming off.Swing arm 6 upper end is provided with circuit board location clamping block 14, and clamping block 14 in circuit board location is by lock-screw locked position.
Being bolted two golden finger fixation kits on upper testing and debugging block 4, two golden finger fixation kits are symmetrical along arm swing support 5 left and right sides.Described golden finger fixation kit includes golden finger fixed block 10, and golden finger fixed block 10 is bolted golden finger stator 9, clamping test golden finger between finger fixed block 10 and golden finger stator 9.
In arm swing support 5, center is provided with shifting axle linear bearing 23, and linear bearing 23 upper end is provided with the c-type clasp 21 preventing shifting axle 20 from coming off.Be slidably installed in shifting axle linear bearing 23 shifting axle 20, and shifting axle 20 lower end is bulb, and the inner face of swing arm 6 is close in bulb both sides.Shifting axle 20 upper end is threaded connection circuit board cushion block pedestal 19, and circuit board cushion block pedestal 19 upper end connects circuit board cushion block 16, and circuit board cushion block 16 upper end is provided with the vacuum WAND 15 being pressed on by circuit board on circuit board cushion block 16.It is provided with compression spring 22 between described arm swing support 5 and circuit board cushion block pedestal 19.
