The operation principle of this manipulator is described below:
Before work, workman is first put into each workpiece to be processed in the material cover 82 of charging tray assembly, starts manipulator.
First the first cylinder operation, drives first, second slide block along guide rail movement, and first, second slide block drives pedestal to point assemblies along guide rail movement together with two.When first-hand finger assembly moves to charging tray top, the first cylinder quits work; Meanwhile, the positioning cylinder of the first positioning component is started working, and locating piece is inserted in the locating slot on pedestal, and pedestal is locked, and the vibrations while avoiding work make to point assembly dislocation, affects the accuracy of work.Two the 3rd cylinder work, promote 90 ° of substrate rotating, make clamping plate subtend workpiece.
First-hand finger assembly work.Finger cylinder operation, piston, when promotion transfer block is outwards mobile, drives the second drive link, the first drive link action successively, makes contiguous block drive clamping plate to expand outwardly when moving to workpiece direction, and retaining ring is outside workpiece.Then the piston rod retraction of pointing cylinder, above-mentioned each parts counteragent, inwardly retracts clamping plate, thereby by piece-holder between each clamping plate.
After finger assembly grabbing workpiece, the piston rod retraction of the 3rd cylinder, makes base plate strip start the reverse 90 ° of retractions of finger assembly.Meanwhile, the positioning cylinder work of the first positioning component, piston rod is retracted, spacing to pedestal of cancellation.Then the first cylinder operation, promotes pedestal and moves along guide rail, makes the station of workpiece subtend lathe; The second positioning component work, the piston rod of the second positioning cylinder stretches out, and locating piece is inserted in locating slot, limits the position of finger assembly; Meanwhile, the finger cylinder operation of first-hand finger assembly, sends workpiece into lathe station; Meanwhile, each clamping plate of first-hand finger assembly extend out, and unclamp workpiece; Now point spring after cylinder and withstand workpiece, before lathe station clamping work pieces, make that workpiece can not become flexible, displacement.Then, the piston rod retraction of finger cylinder, the clamping plate of first-hand finger assembly inwardly shrink when bouncing back in housing.
Above-mentioned finger assembly is when work, owing to being provided with shockproof assembly, so under the cushioning effect of spring, the vibrations of finger assembly are dwindled greatly, good operating stability.
In the time of above-mentioned the first cylinder operation, the second cylinder is under the promotion of pedestal, and drive the 3rd, Four-slider move along guide rail together.
Workpiece is on lathe after completion of processing, and the cylinder of the second positioning component bounces back, and cancellation is spacing to pedestal; The second cylinder operation, promotes pedestal and moves along guide rail together with first, second slide block, makes the manufactured workpiece of clamping plate subtend of second finger assembly; Now, the 3rd positioning component work, is inserted in locating slot the locating piece of the 3rd positioning component.The work of second finger assembly, first clamps workpiece, then retraction.The first cylinder operation, moves together with two finger assemblies pedestal along guide rail, make first-hand finger assembly subtend charging tray, captures workpiece to be processed.
In first-hand finger assembly work, second finger assembly is also done same action, unclamps the workpiece processing, and the workpiece processing is fallen in the second charging basket.
After a workpiece on charging tray assembly is crawled, driver plate cylinder operation, promotes driver plate and rotates along central shaft, thereby make push rod on driver plate promote toothed disc, rotates.Toothed disc drives charging tray to rotate together, workpiece in next material cover is positioned at and treats crawl position.Then the piston rod of driver plate cylinder retraction, goes back to original position by driver plate, and push rod slips over the gear teeth at round and smooth oblique angle on toothed disc, is retracted into original position, between rear gear teeth and the previous gear teeth.So repeat, the workpiece on charging tray can be delivered to crawl station one by one.
When workpiece to be processed changes size, can turn handwheel according to the actual size of workpiece, make central shaft together with moving or move down on whole charging tray assembly, thus adaptive workpiece size.
