Description
Technical field
The invention belongs to automobile manufacturing field, more particularly to a kind of position-limit mechanism of machining center feeding drawer.
Background technology
With the reach of science, the living standard more and more higher of people, automobile use in daily life is also increasingly
Frequently, as essential daily necessities.
The production of automobile is related to automated production, wherein inevitably to be transported to workpiece and feeding.However,
At this stage due to automaticity not enough, many steps do not have complete realization automation, it is necessary to staff in procedure
The collaboration of work cooperative mechanical is completed.
For example, machining center feeding drawer is by way of manual push-and-pull, by workpiece by defeated before machining center at present
Raceway is sent to be delivered on the processing tool inside machining center, and after work pieces process terminates, workpiece passes through drawer again, by processing
Frock is transported to raceway before machining center, then carries out the processing of rear operation.
But during manual push-and-pull, because of employee's subjective factor, easily produce drawer push-and-pull situation not in place.In drawer
Push-and-pull state not in place, workpiece still is able to be pushed into or pulls out, but now drawer and processing tool apart from excessive, workpiece is being pushed away
When entering or pulling out, workpiece is easily turned over and stuck up, and workpiece completes polished surface and collided with alignment pin, and workpiece surface is broken
Bad, workpiece is scrapped.Employee's Manual push-pull subjective factor is big, it is impossible to control its certain push-and-pull in place, and machining center does not have at present
Whether push-and-pull drawer is detected in place, therefore produces substantial amounts of workpiece to scrap.
For this reason, it is necessary to design a kind of position-limit mechanism of machining center feeding drawer so that workpiece feeding drawer less than
Frock cannot be pushed into during position and causes workpiece damage so as to produce to turn over to stick up.
The content of the invention
It is an object of the invention to provide a kind of position-limit mechanism of machining center feeding drawer, it is intended to solve existing feeding and take out
Drawer is not in place to trigger workpiece to turn over the problem for sticking up damage.
