Description
Technical field
The present invention relates to numerical control press field, relate in particular to the split type plate floating clamp on numerical control press.
Background technology
At present, when numerical control press machining sheet, owing to impacting, frequency is high, to impact inertia large, and sheet material there will be larger the beating of amplitude, so clamp is modified into floating type; The applicant is 200820160567.5 in the application number of application on September 28th, 2008, name is called " floating type sheet-material gripping tongs on a kind of numerical control press ", the mode of floating connection between a kind of cylinder body and clamp block is provided, simultaneously, clamp block is provided with contiguous block (being dovetails), is fixed on the crossbeam of numerical control press by monoblock type dovetail mount (clamp block is connected with dovetail mount); In actual applications, existence processing, entirety are assembled complexity, operation is many, and precision reliability is poor, and cost is higher, clamp sheet material part and there will be the problems such as distortion.
Meanwhile, often occur the situation (as shown in figure 10) that plate moves with respect to clamp in real work, cause occurring that the reason of this situation is a lot, during such as die-cut unbalance loading, clamp translation, plate suffers resistance etc.The clamp that the unit for this reason having uses on numerical control press some with the equipment that sheet material clamping situation is detected, such as adopting photoelectricity touch-type checkout gear,
One is electric switch formula, and when board clamp is on clamp, while contact with locating piece, the equipment on clamp lower clamp of being arranged on is compressed, and two contact heads are collided, thereby make equipment work.In the time of work, for a certain reason, sheet material and clamp locating piece depart from, and this equipment separates two contact heads by recoil of spring, and equipment quits work, and owing to being connected with lathe by data wire, lathe is quit work, and workpiece is scrapped substantially.In actual process, the requirement on machining accuracy of general sheet metal component is not high, even if the problem departing from clamp locating piece occurs plate for a certain reason, as long as control within the specific limits, the plate precision processing still meets the requirements.The second is the optoelectronic switch formula that the inventor conceived, and optoelectronic switch is set on lower clamp, the position relationship for detection of a set of clamp separately and between plate.
But, the equipment of photoelectricity touch-type is installed on lower clamp, and the tactic pattern that position is forward, the drawback existing, the one, in the time there is disengaging problem in plate in process, often the positioning precision of lower clamp is also affected, but this equipment cannot detect and adjust in time, finally can affect in batches the machining accuracy of panel beating.The 2nd, in the course of the work, the vibration that clamping has the lower clamp of plate come by the conduction of drift-plate, causes a Photoelectric Detection life-span not long, and accuracy of detection is not high.
