Description
Technical field
The invention belongs to press technologies fields, and in particular to a kind of crank press eccentricity hydraulic regulating device.
Background technique
The crank of usual crank press is an one-piece parts, and position is relatively fixed to be cannot be adjusted.Or use machine
Tool formula adjustment mode due to the limitation of mechanical structure, is merely able to manually adjust or its position of shutdown adjustment during the adjustment
It sets, it is time-consuming and laborious.
Summary of the invention
In order to overcome the disadvantages of the above prior art, the purpose of the present invention is to provide a kind of crank press eccentricity liquid
Regulating device is pressed, can be realized the real-time adjusting of crank eccentricity, it is time saving and energy saving.
In order to achieve the above object, this invention takes the following technical solutions:
A kind of crank press eccentricity hydraulic regulating device, including transmission shaft 7,7 both ends of transmission shaft pass through first bearing
31, second bearing 32 is connected on fuselage 4, has four grooves on the middle part of transmission shaft 7, two grooves of middle and upper part and
Two grooves of lower part are symmetrical, and plunger 5 is equipped in groove, and the outside of plunger 5 and eccentric hoop 6 connect, four plungers 5 and transmission
Axis 7 forms closed containing cavity A, B, C and D, and an oil circuit of transmission shaft 7 is connected to closed containing cavity A, closed containing cavity B, another oil circuit
It is connected to closed containing cavity C, closed containing cavity D；
One end end of transmission shaft 7 is equipped with swivel joint 2, two oil circuit one end of swivel joint 2 and the two of transmission shaft 7
Oil communication, two oil circuit other ends of swivel joint 2 are connect with hydraulicdirectional control valve 1；The other end and press machine of transmission shaft 7
Driving device connection.
Processing is there are two plane F1, F2 on the transmission shaft 7, on eccentric hoop 6 also processing there are two corresponding plane G1,
G2, plane G1, G2 cooperate with plane F1, F2 on transmission shaft 7 during installation, torque and revolving speed are transmitted, to realize eccentric hoop 6
Same-phase rotates simultaneously with transmission shaft 7.
The invention has the benefit that by the commutation of hydraulicdirectional control valve 1, control enters closed containing cavity A, B or C, D
Oil liquid amount is subjected to displacement so that plunger 5 will push eccentric hoop 6, the center of eccentric hoop 6 and the distance between the center of transmission shaft 7
To change, the real-time adjusting of crank eccentricity can be realized, it is time saving and energy saving.
