Numerical control machining center efficiently exchanges clamping device
The utility model relates to a kind of Precision NC machine center fixture, in particular, relates to a kind of a kind of numerical control machining center producing middle rapid interchangeable location and efficiently exchanges clamping device.
In existing numerical control machining center processing process, single processing is generally for processed product, after machining previous product, product need be taken out one by one and load square fixture more one by one and can start board processing, or product is when replacing installation and exchanging plate, need locate fastening one by one, the clamping time is long, and efficiency is low; And the operating cost of lathe is substantially fixing, but process is divided into process time and clamping time, only have be at real converted products process time, and the processing interval clamping time itself is the not creation of value, waste the process time of lathe, reduce the production efficiency of lathe, thus, how reducing the clamping time, is one of key factor of enhancing productivity.
Summary of the invention
Technical purpose of the present utility model overcomes in prior art, numerical control machining center in process of production clamping product is consuming time and then affect the technical problem of production efficiency, provides a kind of and reduces the clamping stand-by period and the numerical control machining center that simultaneously can improve the stability that processing is exchanged efficiently exchanges clamping device.
Numerical control machining center efficiently exchanges clamping device, include base plate, fixed head is provided with in the middle of described base plate, described fixed head is provided with alignment pin, is provided with an assembling clamping structure in the side of described fixed head, and institute's clamping structure includes the cylinder be provided with on base plate, described cylinder is connected with connecting rod, above described connecting rod, be provided with exchange plate, exchange plate and be provided with material alignment pin and locating hole, between fixed head and quick pressing plate, rotating shaft is connected with pressure arm.
Further, described exchange plate is provided with product screens.
The utility model makes the exchange plate of two identical precise measures, and processes the position, hole coordinated with fixed head.Stablize for reaching clamping, fast, efficient object, is made into horizontal base by fixture, and fixed pedestal is installed the fixed head with pilot pin, and pedestal both sides increase independently, nothing interferes cylinder and interlock quick clip, smooth and easy to guarantee handling material.Machine to exchange on plate while product processing first, product put into by other exchange plate, after product completes processing on first exchange plate, takes out first and exchange plate and product, directly change the exchange plate putting product well, take out one by one and clamping without the need to product.
Advantageous Effects of the present utility model is: realize clamping in processing simultaneously, the power generating ratio clamping time, enhance productivity.

Detailed description of the invention
Composition graphs 1, efficiently exchange in the structure of clamping device at the utility model numerical control machining center, include base plate 108, fixed head 106 is provided with in the middle of described base plate 108, be provided with an assembling clamping structure in the side of described fixed head 106, institute's clamping structure includes the cylinder 107 be provided with on base plate 108, and described cylinder 107 is connected with connecting rod 103, be provided with above described connecting rod 103 and exchange plate 101, exchange plate 101 and be provided with material alignment pin 104 and locating hole 109.At the opposite side of fixed head 106, same cylinder 107 and connecting rod 103 structure, the quick pressing plate 102 be located on connecting rod 103 exchanges plate 101 for fast-holding, and described fixed head is provided with alignment pin 105, and between fixed head 106 and quick pressing plate 102, rotating shaft is connected with pressure arm.In force, described exchange plate 101 is provided with product screens.
In force, first process two pieces and exchange plate 101; Exchange plate 101 by first piece on the table to put by machine direction, get product 100 correspondence put into exchange plate 101 alignment pin 104 on location, then the alignment pin 105 that the locating hole 109 exchanged on plate 101 is aimed in fixed head 106 is inserted in; Start air valve, quick pressing plate 102 presses down and product 100 and exchange plate 101 is compressed; Start machining center button to process product 100.Product 100 is loaded second while Product processing and exchange plate 101, after treating first Product processing exchanged on plate, start air valve, unclamp cylinder and quick pressing plate 102, take off first and exchange plate, load the exchange plate of the second packaged good product, cycle operation like this; Processing interval shuts down the contrast of clamping time: be that the sleeve clamp of J42 goes out 4 calculating with one with product type, existing clamping takes out and the load time is about 25 seconds, and adopts this practical technology clamping time to be about 12 seconds, and clamping efficiency improves greatly.
