Abstract
The utility model discloses a press die height hydraulic locking device in the field of presses, which comprises a ball screw. The upper end of the ball screw is in threaded connection with a connecting rod, a stepped piston is arranged between the lower end of the connecting rod and the ball screw, a threaded hole at the center of the piston is in meshed installation with the ball screw, a cavity engaged with the piston in installation is arranged on the connecting rod, the piston includes an upper small-diameter section and a large-diameter section below the small-diameter section, gaskets are respectively arranged between outside of the large-diameter section and the inner wall of the cavity and between the outside of the small-diameter section and the inner wall of the cavity, and an oil inlet-outlet pore communicated with a cavity on the upper side of a large-diameter section step is arranged on the connecting rod. In work, hydraulic oil is filled into the cavity on the upper portion of the large-diameter section of the piston through the oil inlet-outlet pore, and oil pressure leads pull force to be generated between the ball screw and the connecting rod so as to eliminate thread clearance between the ball screw and the connecting rod, thereby leading a dead-center position below a slider to be precisely adjusted and accordingly increasing processing precision of a press.
Description
Technical field
The utility model relates to a kind of forcing press height of packing compact hydraulic locking apparatus, belongs to the press technologies field.
Background technology
In the prior art, a kind of forcing press is arranged, be provided with worm gear, worm component in its slide block, the worm gear center is provided with ball screw, sells to be in transmission connection ball screw upper end and connecting rod screw-threaded engagement between ball screw and the turbine, can drive ball screw by worm and gear rotates, change the relative position of ball screw and connecting rod, the elemental height and the terminal point height that are installed in the mould on the slide block change, and realize the adjusting of height of packing compact.Owing to for being threaded, have thread pitch between the two between ball screw and the connecting rod, influenced the forcing press precision, can not effectively guarantee slide block bottom dead centre precision.
The utility model content
The purpose of this utility model provides a kind of forcing press height of packing compact hydraulic locking apparatus, makes it can eliminate gap between ball screw and the connecting rod, and lower dead point position can more accurately be adjusted.
The purpose of this utility model is achieved in that a kind of forcing press height of packing compact hydraulic locking apparatus, comprise ball screw, be threaded on the ball screw with between the connecting rod, be provided with step-like piston between described connecting rod lower end and the ball screw, the screwed hole at described piston center and ball screw engagement are installed, connecting rod is provided with the cavity that cooperates installation with piston, described piston comprises the big footpath section of superposed path section and path section downside, big footpath section and path section outward respectively and be provided with sealing ring between the cavity inner wall, connecting rod is provided with the cavity that the turnover oilhole is connected big footpath section step upside.
During the utility model work, in the cavity on section top, the big footpath of piston, charge into hydraulic oil by the turnover oilhole, hydraulic oil is limited between the sealed at both ends circle, it upwards pushes connecting rod, pushes piston downwards, and both active forces can act on the ball screw, between ball screw and connecting rod, produce pulling force, eliminate the thread pitch between ball screw and the connecting rod, make the slide block lower dead point position accurately to adjust, to improve the machining accuracy of forcing press.Compared with prior art, the utility model can be eliminated the thread pitch between connecting rod and the ball screw, has realized the accurate adjusting of height of packing compact, has improved the precision of forcing press, and it is easy for installation, and control is reliable.
When avoiding work, piston rotation changes height of packing compact, is provided with straight pin between the path section of described piston and the connecting rod, and the axis of straight pin parallels with the ball screw axis, correspondence is provided with pin-and-hole on connecting rod and the piston, and straight pin inserts in the described pin-and-hole movably.But the straight pin limited piston is rotated, and piston can only be moved up and down, and prevents that the position of adjusting from changing.
Be the lower end position of limited piston, described connecting rod bottom is provided with the spacing gland of limited piston lower end position.
Description of drawings
Fig. 1 is the utility model structural representation,
Wherein, 1 connecting rod, 2 ball screws, 3 oil inlet and outlets, 4 pistons, 5 spacing glands, 6 sealing rings, 7 straight pins.
The specific embodiment
As shown in the figure, be forcing press height of packing compact hydraulic locking apparatus, comprise ball screw 2, be threaded between ball screw 2 upper ends and the connecting rod 1, be provided with step-like piston 4 between connecting rod 1 lower end and the ball screw 2, the screwed hole at piston 4 centers and ball screw 2 engagements are installed, connecting rod 2 is provided with the cavity that cooperates installation with piston 4, described piston 4 comprises the big footpath section of superposed path section and path section downside, big footpath section and path section outward respectively and be provided with sealing ring 6 between the cavity inner wall, connecting rod 1 is provided with the cavity that turnover oilhole 3 is connected big footpath section step upside; Be provided with straight pin 7 between the path section of piston and the connecting rod 1, the axis of straight pin 7 parallels with the ball screw axis, and correspondence is provided with pin-and-hole on connecting rod 1 and the piston 4, and straight pin 7 inserts in the described pin-and-hole movably; Connecting rod 1 bottom is provided with the spacing gland 5 of limited piston lower end position, and spacing gland 5 can stop that piston 4 is descending, has limited the lower end position of piston 4, reached between regulating piston 4 and the connecting rod 1 can oil-filled cavity size purpose.
This device charges into hydraulic oil from oil inlet and outlet 3, makes in its cavity between piston 4 and connecting rod 1 and produces oil pressure; Push piston 4 and connecting rod 1, eliminate the thread pitch between ball screw 2 and the connecting rod 1, can prevent that ball screw 4 from rotating simultaneously.
