The arc and linear movement mechanism disclosed by the utility model has relatively high moving precision.
Description
Technical field
The utility model relates to a kind of circular arc and straight-line motion mechanism.
Background technique
In mechanical transmission mechanism; Straight line and circular arc action isolated mix use condition and occur in a large number; Example is at the forms of motion of lathe cutter saddle; Therefore straight line and circular arc transmission become requisite important crucial conveyer in various lathes, the mechanical mechanism, and its kinematic accuracy, controlling method are the problems of pursuing in the Machine Design.
Generally adopt the screw lead screw pair to satisfy kinematic accuracy in this type of mechanism, existing screw lead screw pair is furnished with frame and forms the screw screw mechanism.Usually screw is a mobile member, is the balance peripheral force, need be equipped with feed rod or guide pillar leads, the screw complex structure, and because of forming support beam structure, the integral rigidity of drive part is poor slightly, the transmission accuracy that influence is whole.
Summary of the invention
Therefore, the utility model provides higher circular arc of a kind of kinematic accuracy and straight-line motion mechanism to present circular arc and the poor slightly defective of straight-line motion mechanism precision.
The technological scheme that the utility model adopts is:
A kind of circular arc and straight-line motion mechanism according to the utility model; Comprise the first screw screw mechanism and the second screw screw mechanism that quadrature is provided with; Wherein the first screw screw mechanism is frame with the body; The second screw screw mechanism is a frame with the slide blocks of the first screw screw mechanism, and said body is formed with one and cooperates with said slide blocks and form the guiding groove of sliding pair.
Circular arc and straight-line motion mechanism according to said structure; The guiding groove that employing is formed on the body leads; The rigidity of guide structure depends on the quiet rigidity of body, and the quiet rigidity and the dynamic stiffness of non-traditional support beam that guide pillar forms, integral rigidity improves greatly; Thereby, make the kinematic accuracy of screw screw mechanism obtain than higher lifting.On the other hand, support beam is long more, and support stiffness is poor more, but based on this structure, then can not receive this restriction, and the restriction ratio that guide structure length receives is less.
Above-mentioned circular arc and straight-line motion mechanism, the notch of said guiding groove are upwards.
Above-mentioned circular arc and straight-line motion mechanism are formed with the line slide rail with this slide blocks moving direction quadrature on the said slide blocks, constitute the guide structure of the slide block of the said second screw screw mechanism.
Above-mentioned circular arc and straight-line motion mechanism, the said first screw screw mechanism and the second screw screw mechanism all adopt the ball wire master screw secondary.
Above-mentioned circular arc and straight-line motion mechanism, the said first screw screw mechanism and the second screw screw mechanism all are furnished with the encoder of real-time collection guide screw movement status information.
Description of drawings
Below in conjunction with Figure of description the technological scheme of the utility model being done further to set forth, is that those skilled in the art better understands the utility model.Wherein:
Fig. 1 is the main TV structure formula intention according to a kind of circular arc of the utility model and straight-line motion mechanism.
Fig. 2 is the plan structure schematic representation corresponding to Fig. 1.
Among the figure: 1, body, 2, X is to ball screw, 3, slide blocks, 4, X is to retarder; 5, X is to actuating motor, and 6, X is to encoder, 7, guiding groove, 8, Y is to slide rail; 9, Y is to ball screw, and 10, Y is to worktable, 11, Y is to retarder; 12, Y is to actuating motor, and 13, Y is to encoder, 14, PLC.
Embodiment
Attaching shown in Fig. 1 and 2 with reference to explanation, is that the basis describes with the X in the numerical control system, Y to axle among the figure, and what arrow was represented is relevant slide block/slide blocks movement direction.The adjustment interval of Y direction is less than the X axle among Fig. 2, consider two adjustment directions of quadrature long should rigidity higher, the short scheme that can adopt the lower and comparative maturity of cost.
Among Fig. 2, on body 1, be formed with guiding groove 7, form the X spindle guide to, slide blocks 3 cooperates the formation sliding pair with this guiding groove 7, manufacture moulding, can adopt unit bore system to manufacture.X is in ball screw 2 is built in said guiding groove 7 basically among the figure, compact structure.And then, connect with drive X that X rotates to ball screw 2 to retarder 4, X to actuating motor 5, X to encoder 6.
And then, making or on slide blocks 3, install Y on the slide blocks 3, leading through track to slide rail 8, its quiet rigidity also is higher than support beam structure, even if short Y also can obtain higher relatively guiding accuracy to guiding.
So, accordingly, Y is installed on slide blocks 3 to ball screw 9, and be equipped with Y to the Y of nut to worktable 10, Y to retarder 11, Y to actuating motor 12, Y to encoder 13 with handle the PLC 14 of this mechanism.
Concrete method of work is following: on body 1, accurately process support holes and the guiding groove 7 of X to ball screw 2 is installed; Slide blocks 3 is fixed; Ball nut and X to ball screw 2 as diagram with bearing fixing in the built-in hole at body 1 two ends; And to guarantee that slide blocks slides flexibly along directions X, slide blocks 3 is good with guiding groove 7 relative engagement.Do not have move left and right, be equipped with X to retarder 4 at X to the ball screw right-hand member, X to encoder 6, guarantees that the directions X slide blocks drives accurately to actuating motor 5 and X.
2 Y are housed to slide rail 8 on slide blocks 3; This slide rail is a linear rail, and Y connects supporting Y to worktable 10 to the linear rail slide block, on slide blocks 3, also fixedly is equipped with Y to ball screw 9; Y connects the pair of nut of Y to ball screw 9 below worktable 10; Y rotates to leading screw, drive Y and move to direction along Y to worktable 10, Y to ball screw 9 one ends be equipped with Y to retarder 11 with Y to actuating motor 12, Y to encoder 13.
When we need straight line motion, just can handle X and move by the PLC electric control system by pre-designed software program to actuating motor, drive X and move along guiding groove and accurate controlled directions X to ball screw, reach our motion requirement.Same also can have PCL control Y direction actuating motor to move when we require Y direction straight line motion, drives Y to the motion of worktable Y direction, and the straight line that reaches the Y direction accurately moves.
When we need circular motion, just can move by directions X actuating motor and Y direction actuating motor simultaneously by PLC electric control system program on request, synthesize accurate circular motion and reach our motion requirement.
Characteristics according to said structure are high precision driving mechanisms built-in fully and that design uses actuating motor to control, can realize that X, Y both direction straight line accurately move according to our requirement.Realization X, Y direction are moved simultaneously, and then are synthesized the working platform of circular motion.Realize this function of machinery completion of different demands.And according to the operating mode demand, this mechanism that produces the different size size is used for different places.
