Automatic feeding device for grooving machine
Technical field
The present invention relates to a kind of automatic blanking device of groover.
Background technology
Groover is Full-automatic numerical control machine tool, professional production pcb board milling cutter, brill such as to chew at the Special precision cutter, higher in automation requirement, particularly require higher to blanking automation, because the quality of blanking system is directly connected to the quality of product, especially high-accuracy cutter quality requires very tight especially, slight breach is by scrapping of being directed at that milling cutter or brill chew, largely add the production cost of enterprise, what existing groover blanking adopted is collet-type blanking device, its structure is the circular collet chuck of made from copper, material is pulled up from board, and then push out, the cutting edge position of cutter is touched in blanking process, likely operation is caused to cutter, affect product quality.
Summary of the invention
The invention provides in a kind of blanking process and directly do not contact with the cutting edge position of cutter, thus damage can not be caused to cutter, the automatic feeding device for grooving machine improved the quality of products.
The object of the present invention is achieved like this: a kind of automatic feeding device for grooving machine, comprise body, cylinder is arranged on body, body upper is pressing plate, lower feed collet is arranged on body by movable rotation-shaft, the push rod be connected with cylinder matches with lower feed collet lower end, is also provided with return spring at body, and return spring matches with lower feed collet.
Automatic feeding device for grooving machine provided by the invention, adopt lower feed collet to pick up the cutter processed, the shank that during blanking, manipulator will directly be clamped milling cutter or brill and chews, can not touch the cutting edge position of cutter again, also can not cause operation to cutting edge roundness, reach the object of Improving The Quality of Products.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described.
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
As shown in Figure 1, a kind of automatic feeding device for grooving machine, comprise body 1, cylinder 2 is arranged on body 1, body 1 top is pressing plate 3, and lower feed collet 4 is arranged on body 1 by movable rotation-shaft 5, and the push rod 6 be connected with cylinder 1 matches with lower feed collet 4 lower end, also be provided with return spring 7 at body 1, return spring 7 matches with lower feed collet 4.
When the present invention uses, cylinder 2 works and drives push rod 7 to run, push rod 6 rotates around movable rotation-shaft 5 after making lower feed collet 4 lower end stressed, lower feed collet 4 upper end is opened, after picked cutter enters lower feed collet 4 upper end open, cylinder 2 return, good tool clamping is taken out in the effect of return spring 7 by lower feed collet 4, complete blanking, cylinder 2 enters the circulation of next feeding after again starting.
