Abstract
The utility model relates to an ultra-precision servo press, which comprises a base, a column frame and a pressure head. An operating space is formed between the base and the pressure head, the pressure head is connected with a servo motor through a ball screw, and a pressure sensor is additionally mounted on the pressure head and electrically connected with the servo motor. By the aid of the ultra-precision servo press, the movement of the pressure head can be more precisely controlled, the precision of the servo motor and the ball screw is relatively improved, and cost is lower.
Description
Technical field
The utility model relates to a kind of servo-pressing machine, relates in particular to a kind of ultraprecise servo-pressing machine.
Background technology
The situation that punching machine and hydraulic press are being commanded the deformation processing technical market has always been broken in the appearance of servo-drive technology, no matter is that servo-pressing machine all has more advantage from the mechanical efficiency or the angle of energy utilization rate.
Referring to Fig. 1; Existing servo-pressing machine comprises a base 10; One pylon 20 and a pressure head 30 form working space between base 10 and the pressure head 30, and pressure head 30 links to each other with a ball-screw 50; This ball-screw 50 moves up and down under the drive of servo motor 40, and then drive ram 30 press-fits operation in working space; Forcing press is provided with a pressure sensor; The reaction pressure that it can perception pressure head 30 passes over through ball-screw 50; Yet the core technology of servo motor 40 and ball-screw 50 is not at home, and all there is certain error in domestic production to them; Thereby there is certain error in the pressure sensor sensed pressure, and then servo-pressing machine is made a discount to the accurate control of pressure head 30; The precision of servo motor 40 and ball-screw 50 is high more in addition, and the price of servo-pressing machine is more expensive.
Summary of the invention
The technical problem that the utility model will solve provides a kind of cheap ultraprecise servo-pressing machine that can accurately control ram movement.
The ultraprecise servo-pressing machine of the utility model comprises a base, a pylon and a pressure head; Form working space between base and the pressure head; Pressure head links to each other with a servo motor through a ball-screw, on pressure head, installs a pressure sensor additional, and this pressure sensor is electrically connected with said servo motor.
Because the pressure sensor that installs additional is positioned on the pressure head, its perception for pressure is directly, even there are foozle in servo motor and ball-screw, does not also influence its perceived accuracy to the reaction pressure of pressure head, thereby can more accurately control the motion of pressure head; And with respect to the precision that improves servo motor and ball-screw, its cost is lower.
Description of drawings
Fig. 1 is the side view of ultraprecise servo-pressing machine.
The specific embodiment
Combine accompanying drawing and embodiment that the utility model is done further explain at present.
Referring to Fig. 1; The utility model raise the clothes forcing press, comprise a base 10, one pylons 20 and a pressure head 30; Form working space between base 10 and the pressure head 30; Pressure head 30 links to each other with a servo motor 40 through a ball-screw 50, on pressure head 30, installs a pressure sensor 9 additional near at, and this pressure sensor 9 is electrically connected with servo motor 40.
Because the pressure sensor 9 that installs additional is positioned on the pressure head 30, its perception for the pressure of pressure head 30 is directly, and not like the pressure sensor of existing indirect sensed pressure.Even there is foozle in servo motor 40 with ball-screw 50, do not influence its perceived accuracy to the reaction pressure of pressure head 30 yet.
Pressure sensor 9 can be passed to servo motor 40 with the pressure signal of pressure head 30; Servo motor 40 will be according to this more accurate its acting program of pressure signal adjustment; Thereby the utility model can obtain the effect according to the fine setting of pressure signal more accurately servo motor 40, thereby can more accurately control the motion of pressure head 30.
The utility model raise the clothes forcing press, also have the characteristics of miniaturization.The pressure limit of its pressurization is 0.1kN～1kN; Loading stroke range is 0～80mm; The power of servo motor is 0.2kw; Pressing time, scope was 0～10s.
The above only is the preferred embodiment of the utility model; Be not that the utility model is done any pro forma restriction; Though the utility model discloses as above with preferred embodiment; Yet be not in order to limiting the utility model, anyly be familiar with the professional and technical personnel, in the scope that does not break away from the utility model technical scheme; When the technology contents of above-mentioned announcement capable of using is made a little change or is modified to the equivalent embodiment of equivalent variations; In every case be the content that does not break away from the utility model technical scheme, to any simple modification, equivalent variations and modification that above embodiment did, all still belong in the scope of the utility model technical scheme according to the technical spirit of the utility model.
