Description
Technical field
The invention belongs to be machined special purpose machine tool technical field, particularly some need big driving torque, higher
The chip lathe of displacement accuracy or the digital control type Hydraulic Power Transmission System for carrying transmission mechanism etc..
Background technology
With present social continuous development, the cycle requirement of update of the client to product is constantly accelerated；To work
The machining accuracy of part is also improving constantly；Present enterprise gradually steps up the integrated of product, and single product function increases, simultaneously
The volume of partial workpiece also just increases, and the processing capacity of lathe is also more with increase.This just brings to some common process industries
Very big worry.Traditional processing can meet single production in enormous quantities mostly in the past.Constantly update, produce in face of present product
The continuous change of product profile and processing dimension, machine tool can not be just competent at sometimes.For the servomotor of general-purpose machining center
Transmission, there have been many drawbacks, when needing high output torque, just necessary expanded motor, motor increase lathe to servomotor
Energy consumption and volume just and then into multiple amplification.This not only wastes the energy but also wastes the limited hall space of client.
The content of the invention
The deficiency for more than, the present invention develops a kind of digital control type Hydraulic Power Transmission System, is that servo is connected with screw mandrel
Encoder, the displacement that control system is sent according to encoded servo device determine high sensitivity hydraulic motor rotation whether, control
The locked high sensitivity hydraulic motor of hydraulic valve, quick accurate stopping.
The technical scheme is that be accomplished by the following way：A kind of digital control type Hydraulic Power Transmission System, including canine tooth
Wheel, high sensitivity hydraulic motor, encoded servo device, little gear, screw mandrel, spiral pieces and mounting seat, high sensitivity hydraulic motor
Connected by gear wheel, little gear with screw mandrel, high sensitivity hydraulic motor drives bull gear drive, and little gear and screw mandrel and then turn
It is dynamic, spiral pieces are installed on screw mandrel and are done along screw mandrel movable, cutting tool, screw mandrel activity are connected with spiral pieces
It is connected in mounting seat, it is characterised in that：Dust cover is additionally provided with described screw mandrel outer rim, drive lead screw is protected, watched
Encoder is taken on screw mandrel afterbody and mounting seat.
The present invention, PLC technology is realized, program can be changed in the short period of time to meet the processing of various products
It is required that.It improves volume of the moment of torsion of transmission without increasing equipment, is that client saves lower valuable hall space, is needing greatly
Speed quickly can accurately stop when moving.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
In figure：1 transmission gear wheel, 2 high sensitivity hydraulic motors, 3 encoded servo devices, the small tooth of 4 transmissions, 5 screw mandrels, 6 spirals
Sliding block, 7 mounting seats, 8 dust covers.
Embodiment
Known by Fig. 1, a kind of Programmable hydraulic transmission system, by gear wheel 1, high sensitivity hydraulic motor 2, encoded servo
Device 3, little gear 4, screw mandrel 5, spiral pieces 6, mounting seat 7 and dust cover 8 form, and high sensitivity hydraulic motor 2 passes through gear wheel
1st, little gear 4 and screw mandrel 5 connect, and high sensitivity hydraulic motor 2 drives gear wheel 1 to rotate, and little gear 4 and screw mandrel 5 and then rotate,
Spiral pieces 6 are installed on screw mandrel 5 and are done along screw mandrel 5 movable, cutting tool are connected with spiral pieces 6, screw mandrel 5 is lived
Dynamic to be connected in mounting seat 7, encoded servo device 3 is arranged on the afterbody of screw mandrel 5 and mounting seat 7, and screw mandrel 5 rotates, and spiral pieces 6 exist
Moving thereon, encoded servo device 3 rotates according to screw mandrel 5 and measures displacement, when reaching the displacement of machine tool control system setting,
Control system stops the rotation of high sensitivity hydraulic motor 2 immediately, controls the locked high sensitivity hydraulic motor 2 of hydraulic valve, makes machine
The quick accurate stopping of bed.Dust cover is additionally provided with the outer rim of screw mandrel 5, screw mandrel 5 is protected, lengthens its service life.
The present invention, original servomotor is replaced using high sensitivity hydraulic motor, exported in the case of volume-diminished
Moment of torsion also be increased, and hydraulic motor is connected by large and small gear with screw mandrel, spiral pieces it is possible thereby to do it is movable, rise
To the effect of transmission.
The present invention after controller obtains procedure, calculates program middle position using encoded servo device detection displacement
The dfisplacement pulse number of shifting amount, then control system umber of pulse can be issued on the encoded servo device 3 being connected on screw mandrel 5.Servo
Encoder 3 starts to detect the actual pulse number that screw mandrel 5 rotates after the umber of pulse rotated.Control system is to encoder
The signal of high sensitivity hydraulic motor 2 is given while umber of pulse, allows it to rotate.When high sensitivity hydraulic motor 2 drives screw mandrel 5 to rotate
When, when encoded servo device 3 detects that the umber of pulse of rotation reaches the umber of pulse of control system output.Encoder is sent out to control system
Go out signal, control system stops the rotation of high sensitivity hydraulic motor 2 immediately after obtaining signal, and controls the locked Gao Ling of hydraulic valve
Quick property hydraulic motor 2, it is not in malfunction to make it.
