Description

Split type plate floating clamp on a kind of numerical control press
Technical field
The present invention relates to numerical control press field, particularly relate to the split type plate floating clamp on numerical control press.
Background technology
At present, during numerical control press machining sheet, because beating frequency is high, impact inertia is large, sheet material there will be larger the beating of amplitude, so be modified into by clamp floating type; The application number that the applicant applied on September 28th, 2008 is 200820160567.5, name is called " floating type sheet-material gripping tongs on a kind of numerical control press ", provide the mode of floating connection between a kind of cylinder body and clamp block, simultaneously, clamp block is provided with contiguous block (i.e. dovetails), is namely fixed on the crossbeam of numerical control press by monoblock type dovetail mount (clamp block is connected with dovetail mount); In actual applications, there is processing, overall assembling is complicated, operation is many, precision reliability is poor, and cost is higher, and clamping sheet material local there will be the problems such as distortion.
Meanwhile, often occur the situation (as shown in Figure 10) of plate relative to clamp movement in real work, cause the reason occurring this situation a lot, such as when die-cut unbalance loading, clamp translation, plate suffers resistance etc.Some equipment detected with the situation that clamps sheet material of the clamp that the unit for this reason had uses on numerical control press, such as adopts photoelectricity touch-type checkout gear,
One is electric switch formula, and namely when board clamp is on clamp, when contacting with locating piece, the equipment be arranged on clamp lower clamp is compressed, and two contact heads are collided, thus make equipment work.When operating, for a certain reason, sheet material and clamp locating piece depart from, and this equipment makes two contact heads be separated 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 departed from clamp locating piece occurs plate for a certain reason, as long as control within the specific limits, the plate precision processed still meets the requirements.The second is the optoelectronic switch formula that the present inventor conceived, and namely on lower clamp, arranges optoelectronic switch, for detecting the position relationship 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 existed, one is when disengaging problem occurs plate in process, often the positioning precision of lower clamp is also affected, but this equipment cannot carry out detecting and adjusting in time, finally can affect the machining accuracy of panel beating in batches.Two is in the course of the work, the vibration that the lower clamp being clamped with plate comes by drift-plate conduction, and cause the Photoelectric Detection head life-span not long, accuracy of detection is not high.
Summary of the invention
