Abstract
The present invention relates to a numerical control gear grinding machine driven by a linear servo motor. The rectilinear motion of a workpiece along the longitudinal direction of an imaginary rack is directly and numerically controlled and driven by the linear servo motor. A rolling guide rail inside the linear servo motor is a guide rail of the rectilinear motion of the workpiece. Compared with the indirect drive mode of the present servo motor by a screw rod, the machine of the present invention has the advantages of simple structure, mechanical transmission error reduction and favorable processing precision increase.
Description
Technical field
The invention belongs to the grinding machine technical field.
Background technology
Press the numerically controlled tooth grinding machine of generating principle work, emery wheel is represented imaginary tooth bar, forms the relative motion of engaged transmission between workpiece gear and imaginary tooth bar, and finishes the processing of the gear teeth in this transmission process.For this reason, workpiece have around self axis rotatablely move and along imaginary tooth bar rectilinear motion longitudinally.In the present prior art, the numerically controlled tooth grinding machine workpiece is driven through leading screw by servomotor along imaginary tooth bar rectilinear motion longitudinally.For example, point out in the patent specification of China's 95230365, No. 5 " several bevel gear grinding machine beds are touched in numerical control for a short time " by name: " servomotor is done the XY direction plane by mechanical leading screw drive workbench and moved ".The mode of this indirect driving, complex structure has increased source of error, is unfavorable for the raising of machining accuracy.
Summary of the invention
The objective of the invention is, provide a kind of numerically controlled tooth grinding machine that directly drives with linear servo-actuator, to solve above-mentioned the deficiencies in the prior art.Technical scheme of the present invention is: the carriage that workpiece will be installed is connected on the moving component of linear servo-actuator, the stationary parts of linear servo-actuator then is fixed on the lathe bed, the rolling guide of linear servo-actuator inside, be the straight-line guide rail of workpiece, the rectilinear motion of workpiece is driven by linear servo-actuator direct numerical control.Advantage of the present invention is: simplified machine tool structure, reduced mechanical transmission component and source of error, helped the raising of machining accuracy.
Description of drawings
Accompanying drawing 1 is to implement structure principle chart of the present invention when adopting conical wheel.
