Description
Technical field
The present invention relates to screw automatic assembly equipment technical field, be specifically related to a kind of pneumatic automatic tightening screw mechanism.
Background technology
For installation people many employings screwdriver lock-screw of screw, or by semi-automatic locking screw device, locking operation is carried out to screw.Adopt the operating type of screwdriver manual locking screw not only to waste time and energy, and operating efficiency is low, operation intensity is large.And by semi-automatic locking screw device, locking operation is carried out to screw, though reduce very greatly the operation intensity of lock screw, but the complex structure of device, cost is high.
Summary of the invention
Technical problem to be solved by this invention is for above-mentioned defect, provides a kind of pneumatic automatic tightening screw mechanism, and structure is simple, and efficiency is high, and cost is low.
The technical scheme that the present invention solves the employing of its technical problem is as follows:
A kind of pneumatic automatic tightening screw mechanism, comprise cylinder, Work-sheet pressing plate, air screwdriver, workbench, described cylinder comprises master cylinder, countercylinder, described workbench is provided with column, column top is provided with fixed head, master cylinder, countercylinder is separately fixed at fixed head both sides, master cylinder piston bar front end is provided with driving shaft, driving shaft bottom connects Work-sheet pressing plate, Work-sheet pressing plate one end and column are slidably matched, Work-sheet pressing plate upper end is provided with the grip block be slidably matched with column, grip block one end is fixed with described air screwdriver, the other end is connected with countercylinder piston rod, Work-sheet pressing plate and air screwdriver opposite position are provided with the slotted eye passed for air screwdriver, master cylinder drives Work-sheet pressing plate to compress the workpiece placed on the table, slotted eye place is provided with sensor, whether sensor detection workpiece is compacted, after workpiece is compacted, sensor sends signal, countercylinder drives grip block to move down, after the front end of air screwdriver contacts with the screw on workpiece through slotted eye, air screwdriver starts immediately, by screw tightening, moment owing to continuing to tighten after screw-driving exceedes the rated output torque of air screwdriver, air screwdriver stops operating automatically, countercylinder and master cylinder control grip block and Work-sheet pressing sheet reset respectively, prepare to operate next time.
Further, workbench corresponding bottom described Work-sheet pressing plate is provided with limited block, be provided with bottom limited block coordinate with workbench screw bolt, bolt is provided with retainer nut, regulate the height of limited block according to the height of workpiece, carry out spacing to Work-sheet pressing plate, easy to adjust, avoid the degree of Work-sheet pressing plate to Work-sheet pressing excessive, cause damage.
Further, on described grip block, relative position is provided with the through hole passed for driving shaft, and the corresponding column place of grip block is also provided with the sliding sleeve be slidably matched with column, and sliding sleeve coordinates with column, reduces mutual wearing and tearing.
Further, the corresponding column place of described Work-sheet pressing plate is also provided with the sliding sleeve be slidably matched with column, and Work-sheet pressing plate is also provided with sensor, and sensor setting is at slotted eye place, and sliding sleeve coordinates with column, reduces mutual wearing and tearing.
The invention has the beneficial effects as follows: adopt such scheme, respectively with countercylinder, master cylinder, drive Work-sheet pressing and air screwdriver is moved to workpiece place; and automatically by screw-driving, then all automatically reset, automaticity is high; save manpower; efficiency is high, and the structure of entirety is relatively simple, and limited block can limit the height of Work-sheet pressing plate; can conveniently adjust different workpiece; increase applicability, protection workpiece and Work-sheet pressing plate, prevent from damaging.
