Automatic clamping and placing workpiece mechanism on the numerically controlled machine
Technical field
The utility model relates to a kind of Digit Control Machine Tool, relates in particular to and picks and places workpiece mechanism on the workbench in this Digit Control Machine Tool.
Background technology
In the Digit Control Machine Tool field (machining center, milling machine, wood-milling machine etc.), mostly the clamping of workpiece to be processed is manual clamping in the prior art.Behind the clamping, workpiece coordinate system is set in the calibration of workpieces position again.For producing product in batches, also very high to the anchor clamps required precision of fixing usefulness.For short workpiece of single-piece work time, artificial frequent change workpiece efficient is low especially.Need a large amount of operative employees.The board service efficiency is low; And it is very high to use manipulator (robot) to pick and place the workpiece cost.
The utility model content
The utility model technical issues that need to address have provided automatic clamping and placing workpiece mechanism on a kind of numerically controlled machine, are intended to solve the above problems.
In order to solve the problems of the technologies described above, the utility model is realized through following technical scheme:
The utility model comprises: lathe frame and board; On described lathe frame, place workbench; Also comprise: holder; Described holder is placed on the workbench; In described holder, place several workpieces to be processed; At the other grasping mechanism of settling of the lower end side of described board; The lower end central authorities of described board are standard fixtures.
Compared with prior art, the beneficial effect of the utility model is: can realize the automatic clamping and placing of workpiece to be processed, reduce machine idle machine (non-processing) time, reduce personnel demand, reduce labour intensity.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail:
Visible by Fig. 1: the utility model comprises: lathe frame 4 and board 1; On described lathe frame 4, place workbench 6; Also comprise: holder 7; Described holder 7 is placed on the workbench 6; In described holder 7, place several workpieces to be processed 3; At the other grasping mechanism 2 of settling of the lower end side of described board 1; The lower end central authorities of described board 1 are standard fixtures 5.
Holder is fixed on the workbench in the utility model, and workpiece is being positioned on the holder, and standard fixture is used for fixing the workpiece of current processing, uses the grasping mechanism grabbing workpiece.
During the utility model running, board moves to the workpiece position base of having put workpiece, uses grasping mechanism to pick up workpiece, is put into the standard fixture place, clamps standard fixture, and grasping mechanism unclamps, and puts down workpiece; Begin processing.After machining, board moves to the standard fixture place, unclamps standard fixture, uses grasping mechanism to pick up workpiece, is put back on the corresponding holder of this workpiece, unclamps workpiece, moves to next holder position, repeats above-mentioned action, treats all workpieces to be processed completion.
