Background technology
At present, three coordinate measuring machine is mainly used in the measurement of casing in the industries such as middle-size and small-size accessory, mould such as machinery, automobile, aviation, military project, furniture, instrument prototype, machine, frame, gear, cam, worm gear, worm screw, blade, curve, curved surface etc., also can be used in the industries such as electronics, five metals, plastic cement, can carry out precision to the size of workpiece, shape and form and position tolerance and detect, thereby complete the tasks such as piece test, profile measurement, process control.
Traditional coordinate measuring machine is three axles, its structure comprises bearing, is arranged at the stationary work-table on bearing, on stationary work-table, be provided with travelling table and column, column is provided with X crossbeam, X crossbeam is provided with XZ balladeur train, is provided with a set of Z axis motion assembly in XZ balladeur train, in Z axis motion assembly, comprises Z axis, Z axis position is arranged at X-direction middle part on XZ balladeur train, and gauge head unit is installed on Z axis.The three-dimensional coordinates measurement engine efficiency of prior art is low, and repetitive positioning accuracy is poor.
Measuring equipment in prior art three coordinate measuring machine moves back and forth along two parallel guide rails, guide rail adopts metal material to make conventionally, guide rail is in use influenced by environmental temperature, and the phenomenon of expanding with heat and contract with cold is serious, thereby causes the measuring accuracy of three coordinate measuring machine lower.
Reverse engineering technology is current a kind of Parallel Design, development tool for product development and machining simulation, it is the three-dimensional internal and external profile measurement of collection, light groupization technology, laser technology, powder metallurgy, the technology such as quick cast and fast mould manufacture are integrated the new and high technology of (optical, mechanical and electronic integration): it can complete the internal and external profile measurement of various shape products quick high accuracy, and by system data, process the intention that reaches deviser. then utilize rapid shaping technique to make data become observable mock-up, so that businessman takes the preemptive opportunities in market, and obtaining economic interests. three-dimensional measurement technology is the gordian technique in reverse engineering technological system, its effect is mainly reflected in following several respects:
1. design verification: whether the processing dimension that detects part meets drawing requirement, at present critical size is adopted to hand dipping conventionally, for high, the complex-shaped part of accuracy requirement, normal measurement is difficult, workload is large, adopting reverse engineering technology to carry out integral body to part measures, convert measurement data to cad data, in computing machine, measurement data and design data carried out to check analysis.
2. reverse engineer: in actual design effort; the design of designer to designed product; the design idea such as household electrical appliance and automobile etc. with the covering of complex-curved profile; often be difficult to directly express on computers or on drawing; now; mud mould or the wood mould that can first make desired profile, then utilize three-dimension measuring system to carry out Quick Measurement, and the size shape data of model are converted into three-dimensional CAD data.
3. emulation manufacture: dissect and the inside and outside advanced model machine of emulation manufacturing nation or while losing the vital part of supply channel, due to they complex-shaped, precision is very high, is difficult to accurately survey and draw with artificial, especially, for the complicated surface of mould impression, more cannot survey and draw; Can first adopt reverse engineering technology accurately to measure part, then export rapid shaping file layout or CNC machining code, can copy out this part.
In sum; product model is carried out to three-dimensional automatically to measure and the interface with downstream technical process is provided be a step very crucial in reverse engineering technology; producer was able within the shortest cycle; with minimum cost of development; to market, throw in fast new product. from the viewpoint of measuring efficiency and precision two; three coordinate measuring machine precision advantage is outstanding, but efficiency is minimum; Industry CT odds for effectiveness is outstanding, but precision is minimum. because these equipment are all independently single; User can only select a kind of equipment wherein to use, can not take into account precision and efficiency. above-mentioned any one equipment all can not be realized Full Featured performance simultaneously, although can not realize profile and inner chamber are measured simultaneously. a user can buy two kinds of equipment simultaneously, realize taking into account of precision and efficiency, but use cost is too high.
