Abstract

The invention relates to a rotation coordinate axis C'-A' conversion device of a five-axis NC machine tool. On the basis of the five-axis NC machine tool provided with X, Y, and Z straight-line coordinate axes as well as a B-axis (tool swing axis) and a C'-axis (workbench rotation axis), the conversion device is firstly connected with the C'-axis rotation center of a machine tool table through a flange at the end part of an input shaft, then through the meshed driving of a large straight-teeth conical gear and a small straight-teeth conical gear, the rotary motion of the C'-axis is converted into the horizontal rotation motion of a middle shaft, and finally through the meshed driving between a small herringbone-teeth cylindrical gear and a large herringbone-teeth cylindrical gear, the rotary motion of the C'-axis is converted into the A'-axis rotary motion of a turntable fixedly connected on the end part of an output shaft, therefore, the rotation coordinate axis conversion from the C' axis to the A' axis of the five-axis NC machine tool is realized. With the rotation coordinate axis C'-A' conversion device of the five-axis NC machine tool, the machining range of the five-axis NC machine tool is further expanded, the original complex parts difficult to process are conveniently and efficiently processed, and the processing efficiency and the processing precision of the complex parts are improved.

Description

A kind of rotatable coordinate axis C '-A ' conversion equipment of five-axle number control machine tool
Technical field
The present invention relates to a kind of five-axle number control machine tool, the rotatable coordinate axis C ' axle particularly relating to a kind of five-axle number control machine tool converts the device of A ' axle to.
Background technology
Five-axle number control machine tool is typically configured to three rectilinear coordinates axles and two rotatable coordinate axis.Wherein, be configured to X, Y, Z tri-rectilinear coordinates axles and B axle (cutter oscillation axle), the upright type five-shaft Digit Control Machine Tool of C ' axle (work table rotation axle), wherein Z axis is be the rectilinear coordinates axle of positive direction straight up, X-axis is level is to the right the rectilinear coordinates axle of positive direction, Y-axis positive direction can be determined by right-hand rule, again by the positive direction of right-hand rule determination cutter oscillation axle B axle, the negative direction of work table rotation axle C ' axle, due to the restriction of machine tool structure layout and B axle pivot angle stroke, some typical complex curved surface part difficult processing are to realize smoothly, namely enable processing also needs multiple clamping, not only resetting difficulty, and cause mismachining tolerance to be aggravated.Such as in the process of machining space cam, need twice clamping just can process the wide face of complete cam work, processed the lower semisection in the wide face of cam work by first time clamping, then, second time clamping is carried out in workpiece tune, reprocesses out the upper semisection in the wide face of cam work.Because accurate resetting and fairing are connected smoothly very difficult, twice resetting clamping causes machining accuracy seriously to reduce undoubtedly.Therefore, if a kind of rotatable coordinate axis C '-A ' conversion equipment of five-axle number control machine tool can be developed, this Digit Control Machine Tool configuration transitions is made to be X, Y, Z and B axle (cutter oscillation axle), A ' axle (work table rotation axle), then can eliminate the restricted problem of rotation shaft angle stroke range on the one hand, only need clamped one time can complete the processing of this type of complex space curved surfaces part of space cam simultaneously, make difficult processed complex part originally achieve convenient and efficient processing.
Summary of the invention
The C ' rotatable coordinate axis that the object of this invention is to provide a kind of five-axle number control machine tool converts the conversion equipment of A ' rotatable coordinate axis to.
The technical solution adopted for the present invention to solve the technical problems is: be configured to X, Y, Z tri-rectilinear coordinates axles and B axle (cutter oscillation axle), on the five-axle number control machine tool basis of C ' axle (work table rotation axle), conversion equipment is first connected with the platen C ' axle centre of gyration by power shaft end flange, again by large straight bevel gear and little straight bevel gear engaged transmission, the gyration of C ' axle is converted to the horizontal rotation motion of jackshaft, finally by little double helical tooth roller gear and large double helical tooth roller gear engaged transmission, the gyration of C ' axle is converted to output shaft end to be connected the A ' axle gyration of rotating disk, the C ' axle thus achieving five-axle number control machine tool is changed to the rotatable coordinate axis of A ' axle.In order to require consistent with the numerical control programming of lathe, make the numerical control programming of this conversion equipment easy, the gyration of design C ' axle is converted to the be connected resultant gear ratio of A ' axle gyration of rotating disk of output shaft end and is i always =1, such A ' axle rotational coordinates value directly equals C ' axle rotational coordinates value.
Large straight bevel gear of the present invention and little straight bevel gear engaged transmission, its gearratio is i 1=0.2.
Little double helical tooth roller gear of the present invention and large double helical tooth roller gear engaged transmission, its gearratio is i 2=5.
The invention has the beneficial effects as follows: the present invention is on the five-axle number control machine tool basis being configured to X, Y, Z tri-rectilinear coordinates axles and B axle (cutter oscillation axle), C ' axle (work table rotation axle), convert C ' rotatable coordinate axis to A ' rotatable coordinate axis, not only widen the range of work of five-axle number control machine tool further, make difficult processed complex part originally can complete convenient and efficient processing, and improve working (machining) efficiency and the machining accuracy of complex parts.
Accompanying drawing explanation
Fig. 1 is structure front schematic view of the present invention.
1. flanges in figure, 2. large straight bevel gear, 3. power shaft, 4. little straight bevel gear, 5. jackshaft, 6. little double helical tooth roller gear, 7. output shaft, 8. large double helical tooth roller gear.
Detailed description of the invention
In order to make object of the present invention, technical scheme and advantage more clear, below in conjunction with accompanying drawing, the invention will be further described.
On the five-axle number control machine tool basis being configured to X, Y, Z tri-rectilinear coordinates axles and B axle (cutter oscillation axle), C ' axle (work table rotation axle), conversion equipment is first connected with the platen C ' axle centre of gyration by power shaft (3) end flange (1), again by large straight bevel gear (2) and little straight bevel gear (4) engaged transmission, its gearratio is i 1=0.2, the gyration of C ' axle is converted to the horizontal rotation motion of jackshaft (5), finally by little double helical tooth roller gear (6) and large double helical tooth roller gear (8) engaged transmission, its gearratio is i 2=5, the gyration of C ' axle is converted to output shaft (7) end and is connected the A ' axle gyration of rotating disk, the C ' axle thus achieving five-axle number control machine tool is changed to the rotatable coordinate axis of A ' axle.Because the gyration of C ' axle is converted to the be connected resultant gear ratio of A ' axle gyration of rotating disk of output shaft end be i always =i 1 i 2=1, A ' axle rotational coordinates value directly equals C ' axle rotational coordinates value.This both required consistent with the numerical control programming of lathe, made again the numerical control programming of this conversion equipment very easy.
