Description
Technical field
The present invention relates to the rapid shaping technique field, particularly a kind of multistation flat field condenser lens changing device more.
Background technology
Selective laser melting SLM is a kind of method of metalwork straight forming, is the latest development of rapid shaping technique.This technology is based on the basic thought of rapid shaping, i.e. " increment " manufacture of successively cladding, and the part that has geometry in particular according to the three-dimensional CAD model straight forming, in forming process, metal dust melts fully, produces metallurgical binding.Adopting the metal parts that traditional machined means can't produced shape and structure complexity, is one of main direction of using of rapid laser-shaping technique.Have the following advantages:
(1) can directly make the terminal metal product, need not any aftertreatment technology or simple surface treatment, select directly to process the part that can directly use by simple CAD moulding and material, greatly shortened product development cycle;
(2) can obtain having the entity of nonequilibrium state supersaturated solid solution and even tiny metallographic structure, density almost can reach 100%, and the part machinery performance is suitable with the Forging Technology gained;
(3) use the laser instrument with high power density, with the very little laser beam processing metal of hot spot, make the metal parts that processes have very high dimensional accuracy (reaching 0.1mm) and good surface roughness (Ra 30～50 μ m);
(4) because laser spot diameter is very little, therefore can with the lower dystectic metal of power fusing, make the metal dust with single component come finished parts to become possibility, and the metal dust kind that can Gong select also have been expanded greatly;
(5) be fit to the workpiece of various complicated shapes, especially being fit to inside has the complicated abnormal shape structure, as cavity, three-dimensional grid and the complex part that can't make with conventional method.
But on market, the flat field condenser lens of selective laser melting SLM equipment is all fixed now, flat field condenser lens surface can form stain in long-time forming process, focusing to laser beam causes interference, if unclear contaminate mark even can burn flat field condenser lens, cause damage of equipment.Pull down in the process that the flat field condenser lens cleans and to interrupt normal forming process, cause interference to progressive forming.If carry out clean operation in airtight casing, just must open casing and carry out, destroyed the gaseous environment in casing, virtually increased curring time.
Summary of the invention
The invention provides more changing device of a kind of multistation flat field condenser lens, comprise by eyeglass quick-replaceable draw-in groove locator card and be combined in lens unit on rotating disk, predeterminated position at lens unit is provided with limit switch, rotating disk connects with driven by servomotor, servomotor connects cylinder, cylinder and the conducting of Compressed Gas pipeline are provided with magnetic valve on the Compressed Gas pipeline, and described servomotor, cylinder and magnetic valve are connected outside central controller controls and are connected.Avoid the described clean operation process of carrying out in airtight casing, must open casing and carry out, destroyed the atmosphere in casing, virtually increased the defective of curring time.
For achieving the above object, technical scheme of the present invention is:
A kind of multistation flat field condenser lens is changing device more, comprise by eyeglass quick-replaceable draw-in groove 14 locator cards and be combined in lens unit 1 on rotating disk 2, predeterminated position at lens unit 1 is provided with limit switch 7, rotating disk 2 drives with servomotor 3 and connects, servomotor 3 connects cylinder 4, cylinder 4 and 6 conductings of Compressed Gas pipeline are provided with magnetic valve 5 on Compressed Gas pipeline 6, described servomotor 3, cylinder 4 are connected with magnetic valve with outside central controller controls connection.
Described lens unit 1 comprises that scioptics compressing tablet 13 is fixed on the flat field condenser lens 11 on lens fixed frame 12, a side towards flat field condenser lens 11 on lens fixed frame 12 is provided with eyeglass gas side blowing apparatus 16, have air inlet 17 on eyeglass gas side blowing apparatus 16, lens fixed frame 12 relies on locating hole 15 to be locked on eyeglass quick-replaceable draw-in groove 14 by positioning element.
Described magnetic valve 5 is trivial only magnetic valve.
Multistation flat field condenser lens of the present invention is changing device more, the design of employing indexing type, the signal that can send according to the central controller of outside is changed the flat field condenser lens automatically, this multistation flat field condenser lens more changing device also is provided with spacing and locking device, can accurately locate flat field condenser lens position.Multistation flat field condenser lens more changing device is provided with eyeglass gas side blowing apparatus and eyeglass quick-replaceable draw-in groove, can reduce to greatest extent the stained of flat field condenser lens and replacing time.
