Description
Technical field:
The utility model servo electric machine type bender belongs to the driving mechanism field of numerical control bender with worm gearing.
Background technique:
Plate bending machine is pressed the driving mode of slide block and is divided, and can be divided into mechanical bender and hydraulic bending press.
The machinery bender adopts the driving power of threephase asynchronous as slide block, carries out speed change with clutch, and promptly by following technological requirement speed change: slide block begins down fast earlier, it is high speed operation, when bending operation, slide block is following slowly, when the slide block backhaul, high speed operation then, the shortcoming of this structure is a very flexible, is difficult to realize automation and digital control operation, thereby, be difficult to adapt to current production requirement, be eliminated nearly decades.
Hydraulic bending press is the trend of nearly development decades, the slide block moving linearly, oil cylinder is arranged on the wallboard of both sides, connect than being easier to numerical control system, but when upper and lower material, oil pump is also being worked always, so just waste energy, the hydraulic system of lathe temporarily can leakage of oil, but in the long run, lathe always can leakage of oil.Still more, hydraulic work system also needed to change oil after a period of time, so just may cause environmental pollution.
In order to overcome the shortcoming of above two kinds of types, just need development to save energy and protect environment and have the servo electric machine type bender that adopts the worm gearing transmission efficiently, and worm gearing is the principal organ of this servo-electric formula bender.
Summary of the invention:
The purpose of this utility model provides a kind of servo electric machine type bender worm gearing, worm gear with worm meshing is coupled to the ball wire bar pair nut, driving is fixed on the ball screw in the slide block and makes the slide block operation, does not so just need oil cylinder, has solved leakage of oil and has caused environmental pollution problem.
A kind of servo electric machine type bender worm gearing is characterized in that regulating bolt and lock nut (1) and spherical cushion block (13) and is installed in ball screw (2) top and bottom respectively; Dust ring (3) is with in dust ring (14) lays respectively at the upper side cover (4) and following side cover plate (12) that is connected with worm gear case (7) by screw; Upside tapered roller bearing (5) and downside entad angular contact ball bearing (13) lay respectively at outside upside connection axle sleeve (6) and the downside axle sleeve (11), worm screw (8) is meshed with worm gear (9), and be installed in the worm gear case (7), worm gear (9) links with the ball screw nut (10) that is installed on the ball screw (2).
This servo electric machine type bender is as follows with the working principle of worm gearing:
Servomotor output shaft and worm shaft link, when servomotor rotates, then drive the worm drive that is attached thereto, worm screw drives the worm drive that is meshed with it again, and the nut of worm gear and ball wire bar pair is fixed together, and nut is limited in the position of Vertical direction, thereby the rotation of worm gear is converted into the vertical motion of ball screw above-below direction, and the ball screw top and bottom join together by link and slide block, so the vertical motion of ball screw just makes slide block do vertical motion, thereby just replaced the oil cylinder of slide block both sides with the worm and gear transmission case.
According to above-mentioned working principle, now the structure of servo electric machine type bender with the relevant operation part of worm gearing is described as follows:
Left side at slide block, right two ends respectively have an oblong aperture, in each oblong aperture, one cover worm couple respectively is installed, and worm couple is fixed on the wallboard of frame, a left side, the output shaft of right servomotor respectively with a left side, left side in the right worm gear case, right worm shaft links by coupling, for each worm gear case, worm shaft drives worm gear and rotates, the nut of worm gear and ball wire bar pair is fixed together, because of nut Vertical direction position is limited, so worm gear rotates ball screw is done, the lower direction vertical motion, the ball screw lower end by spherical cushion block respectively with a slide block left side, the following end in contact of right oblong aperture is fixed, a left side, right ball screw upper end is respectively by regulating bolt and a locking nut and a slide block left side, the last end in contact of right oblong aperture is fixed, by the adjustment of adjusting bolt and fixing of locking nut, can be with on slide block and the ball screw, the upper/lower positions relative fixed; Designed a fixed block in the lower end of screw mandrel, can prevent that screw mandrel from rotating, the assurance ball screw can only be done upper and lower vertical motion, like this, transmission by worm and gear, make ball screw can only do upper and lower vertical motion, and because of ball screw upper and lower end and slide position are fixed together, thus action when realizing with slide block.
This servo electric machine type bender is as follows with the worm gearing beneficial effect:
1,, the pollution problem that causes leakage of oil and change oil because of hydraulic system, compliance with environmental protection requirements have therefore been overcome owing to the oil cylinder that has replaced the slide block both sides with the worm and gear transmission case.
2, bending precision height, the servo electric machine type bender is that common bender is unapproachable to the bending precision of complex parts.
