Detailed description of the invention
Left socle 2, right support 9 are installed in fixture mounting seat 1 with bearing block 1 and bearing block 2 20, and left transverse slat 12 and right transverse slat 14 are installed on left socle 2 with on the guide pass of right support 9.
By rotating handwheel 4, power transmission shaft 10 is rotated, and power transmission shaft 10 passes motion to screw rod 1 by the engagement of gear 27 and gear 1, and screw rod 1 drives link stopper 1 by threaded engagement, and the left transverse slat 12 that link stopper 1 drives and it is fixed together moves; While left transverse slat moves, power transmission shaft 10 passes motion to screw rod 2 17 by gear 3 18 and gear 4 19 engagement, screw rod 2 17 drives link stopper 2 16 by threaded engagement, link stopper 2 16 drives and its right transverse slat 14 of being fixed together moves, and so just achieves left transverse slat 12 and right transverse slat 14 separately.When left transverse slat 12 separates with right transverse slat 14, by micro parts 13, be manually placed on the correspondence position of left transverse slat 12 or right transverse slat 14, then rotate backward handwheel, left transverse slat 12 is closed with right transverse slat 14.
After left transverse slat 12 and right transverse slat 14 are closed, to cylinder 27 ventilation, gas pawl 25 is moved, thus realize folder and refer to that holder 23 moves, realize the clamping to micro parts 13.
Folder refers to that holder 23 is installed on gas pawl 25, and gas pawl 25 is installed on cylinder 26, and cylinder 26 is installed on cylinder saddle 27, and cylinder saddle 27 under the action of the spring 28, holds 24 by true bobbin and can fluctuate within the specific limits along the axis of guide 22.The domain of walker of cylinder saddle 28, is decided by stop screw 21.
Start to press-fit part after clamping, when pressure assembling force acts on micro parts 13 time, under the action of the spring 28, folder refers to holder 23, gas pawl 25, cylinder 26, cylinder saddle 27 under the action of the spring, moved downward along the axis of guide 22 by linear bearing 24, produced location to avoid micro parts.
After micro parts 13 has assembled, assembly force has been cancelled, and folder refers to holder 23, gas pawl 25, cylinder 26, cylinder saddle 27 under the action of the spring 28, to be moved upward get back to the position before press-fiting by linear bearing 24 along the axis of guide 22.
Now, by rotating backward handwheel 4, power transmission shaft 10 is rotated, power transmission shaft 10 passes motion to screw rod 1 by the engagement of gear 27 and gear 1, screw rod 1 drives link stopper 11 by threaded engagement, the left transverse slat 12 that link stopper 11 drives and it is fixed together moves, left transverse slat is heterodromous while, power transmission shaft 10 passes motion to screw rod 2 17 by gear 3 18 and gear 4 19 engagement, screw rod 2 17 drives link stopper 2 16 by threaded engagement, the right transverse slat 14 that link stopper 2 16 drives and it is fixed together moves, left transverse slat 12 is so made to separate with right transverse slat 14, the workpiece assembled is lifted down.
