Description
Affiliated field
The present invention relates to the traversing multiaxis sychronisation of boring bar on the horizontal boring lathe of a kind of heavy type, particularly adopted a guiding, other axle is followed synchronization-moving boring bar Traverse Displacement Unit.
Background technology
At present, in many industries, all may run into the processing problems of Super Long-axles and deep hole, for example in large-scale hydroelectric generation industry, need use parts such as high-power water power main shaft and large turbo-type generator support, need to process very dark endoporus in this type of part.The horizontal boring lathe of NC heavy that this just need develop the processing of having the ability is used for the processing of this type of part.
Because the borer of this type of heavy horizontal boring lathe processing stroke is grown (reaching 8 meters), the carriage of using in boring bar place palpus installation supplemental support guarantees the rigidity of boring bar in big stroke process, because the diameter difference of processing, boring bar should move laterally within the specific limits, and this just requires the traversing multiaxis of boring bar synchronous.
Summary of the invention
The objective of the invention is at the requirement of heavy parts large diameter, deep borehole bore hole, a kind of traversing multiaxis sychronisation of boring bar that is applied on the heavy horizontal boring lathe is provided.
The technical solution used in the present invention is: the boring bar supplemental support adopts two or more carriages, and identical drive mechanism is all adopted in each carriage traversing; The traverse feed axle of two or more carriages is one group of synchronizing shaft, keeps same moved further, and one of them takes axle as the leading factor, and other is for following synchronizing shaft.
The traversing multiaxis sychronisation of the said boring bar of the present invention, its formation mainly comprises boring bar, two or more carriages, digital control system.
Said boring bar is placed in the upper body of two or more carriages, and the upper body is placed on the slide, and in the traversing process of boring bar, boring bar moves laterally in the slide of carriage separately with the upper body of carriage.Each bracket main body structure comprises: upper body, slide, motor, reductor, feed screw nut kinematic pair, and wherein motor, reductor, leading screw are placed on the carriage slide, and motor links to each other with reductor, and reductor links to each other with leading screw; Leading screw and nut are formed the feed screw nut kinematic pair, and nut is installed in the nut seat, and nut seat is packed on the carriage upper body, and rectilinear motion can be done along the leading screw direction together in nut, nut seat and carriage upper body; The feed screw nut kinematic pair with the rotation of motor be converted into boring bar and carriage upper body in the carriage slide horizontal rectilinear motion.Also has digital control system with the traversing multiaxis sychronisation of said boring bar is complementary.Said digital control system, the output of its SERVO CONTROL link links to each other with motor input on being placed in each carriage slide, is used to control the synchronous rotation of each motor, and is synchronous to realize the traversing multiaxis of boring bar.
Adopt the traversing multiaxis sychronisation of the said boring bar of the present invention, be applied on the heavy horizontal boring lathe,, be enough to finish processing work the large diameter, deep borehole bore hole of parts such as high-power water power main shaft and large turbo-type generator support through check.

Fig. 2: the traversing front rack drive mechanism of boring bar figure;
Fig. 3: electric control theory figure.
The specific embodiment
Below in conjunction with accompanying drawing, the structure and the principle of the traversing multiaxis sychronisation of boring bar of the present invention is further described and illustrates.Accompanying drawing is an example with traversing three sychronisations of boring bar, and only describes with the structure of one group of boring bar Support bracket, and structure of other each group is identical, so do not give unnecessary details.
Fig. 1 is to be the structure chart of example to have three synchronous boring bar Traverse Displacement Units.In the front view boring bar 2 be placed in three carriages 1,1a ..., among the 1n; Outside drawing with A carriage 1 in view is an example, and boring bar 2 is settled in the upper body 3 of carriages 1, and upper body 3 is placed on the slide 4, and boring bar 2 and upper body 3 can move laterally in slide 4 along the U3 direction of principal axis in the diagram (as A among Fig. 1 to shown in the view).
Other carriage, i.e. identical drive mechanism is all adopted in said two or more carriages traversing, and existing is example with the traversing carriage drive mechanism of boring bar among Fig. 2 figure, and the specific embodiment that boring bar is laterally moved explains.As shown in Figure 2, the output of motor 5 links to each other with the input of reductor 6, and the output of reductor 6 links to each other with the input of leading screw 7; Motor 5 and reductor 6 are installed in the end of slide 4, and leading screw 7 is installed in the slide 4, and leading screw 7 can be done gyration in slide 4; Leading screw 7 is installed in groups with nut 8, forms the feed screw nut kinematic pair; Nut 8 is packed in the nut seat 9, and nut seat 9 is packed on the upper body 3, and rectilinear motion can be done along the leading screw direction together in nut 8, nut seat 9 and upper body 3; The feed screw nut kinematic pair with the rotation of motor 5 be converted into boring bar 2 and upper body 3 in slide 4 horizontal rectilinear motion.
For the traverse feed axle of realizing two or more carriages is that one group of synchronizing shaft (keeps same moved further, one of them is guiding, other is for following axle synchronously), the identical drive mechanism of traversing employing of two or more carriages is as long as the synchronous rotation of control motor 5 can realize.
What provide as Fig. 3 is the digital control system schematic diagram, realizes being placed in the functions that the motor 5 on each reductor 6 rotates synchronously.Two or more outputs are arranged on digital control system 10, the traversing drive mechanism device of corresponding two or more carriages, be each output respectively with the servo control unit 11 of each carriage, 11a, 11n (U3, U3a, the U3n axle) input links to each other, servo control unit 11,11a, 11n (U3, U3a, the U3n axle) output and motor 5,5a, 5n (U3, U3a, the U3n axle) input links to each other, and is used to control motor 5,5a, 5n (U3, U3a, the U3n axle) rotation.
Whole U3, U3a ..., the U3n axle is common forms a synchronizing shaft group, digital control system 10 is controlled their position ring, servo control unit 11,11a ..., 11n controls their speed ring.The output of digital control system 10 by servo control unit 11,11a ..., 11n control respectively motor 5,5a ..., 5n synchronous rotation realize that the traversing multiaxis of boring bar is synchronous.
