Description

Flame parallel five toolroom machines

Technical field

The utility model is about a kind of flame parallel five toolroom machines, is meant that especially a kind of the cooperation with flame frame by parallel spatial linkage constitutes one and have the five dimension directions of motion at least and can carry out the technology of the toolroom machine of high efficiency processing.

Background technology

Press, at present traditional flame five toolroom machines are all tandem (serial-link) feed mechanism, and so-called series system is to combine linear feeding axle and rotating shaft are overlapped; Please be simultaneously referring to Fig. 1 (A) and Fig. 1 (B), Fig. 1 (A) is just flame five toolroom machines in volume production of external PARPAS company, Fig. 1 (B) then is the employed main tapping of this machine, this main tapping tool series connection links two independent rotary freedoms (being A/C axle direction of rotation), this type is the present normal adopted configuration of flame five toolroom machines, its X-axis feeding control, be to reach by the main shaft headstock mobile institute on crossbeam that is positioned on the crossbeam, Y-axis feeding control, be by crossbeam along be positioned at door type structure move the institute reach, Z axle feeding control, then be to reach the feeding purpose by moving of headstock, the orientation adjustment that is cooperated as for the A/C axle, controlled by the rotary main shaft head of Fig. 1 (B), so, flame five toolroom machines shown in Fig. 1 (A), its whole framework is to be one group of in-line mechanism basically, and the rigidity of complete machine is as serial spring, if have any one assembly rigidity lower in the whole system, just can make the rigidity of a system reduce because of the relation of train.

The major defect of tandem mechanism, be that cantilever is longer, cause structural load streamline long (longloading path), the rigidity deficiency, structure is subject to the moment of flexure load deformation and structure is hot asymmetrical design problems such as (thermally non-symmetric structure), these problems also often cause the dynamic band width of system to be restricted, be unfavorable for high speed, and present common settling mode, add to solve with its structure of roughing, this mode, not only cause and to promote feed mechanism with bigger drive source, also improve the manufacturing cost height, and caused a large amount of energy resource consumptions; On the other hand, though modern computer Numerical Control (Computer Numerical Control, CNC) can be with computer technology, reduce the geometric error and the thermal deformation of machine in error compensation mode (error compensation), though this kind utilizes software to compensate the mode of machine error, can allow the series configuration toolroom machine, software engineering at lower cost improves accuracy of machines, but the successful prerequisite of Error Compensation Technology, be that machine must have enough repeatability (repeatability), that is machine must have enough rigidity and low thermal deformation etc., and these characteristics all are being difficult to reach on the series configuration toolroom machine at present.

Again, flame five assemblies that the toolroom machine rigidity is minimum and cost is the highest in conventional architectures, the main tapping that has two rotating shafts exactly, to show design that the tandem feed mechanism is applied in flame five toolroom machines and to make, mostly the problem that often runs into is in the rigidity deficiency of five spindle noses and is difficult to high speed, and the needed hierarchy of skill of its manufacturing assembling is quite high, so that the price of flame five toolroom machines is high, if and the rigidity that can improve flame five tool machine spindle heads with reduce cost, will make domestic flame five toolroom machines have more competitiveness.

This shows that the above-mentioned article of commonly using still have the design weak point, real non-one perfect designer, and urgently symbol is improved.

Every shortcoming that this creator derives in view of above-mentioned existing flame five toolroom machines is urgently to think to be improved innovation, and after concentrating on studies through taking great pains to attain one's goal for many years, successfully flame parallel five toolroom machines of this part are finished in research and development finally.
