Summary: | The utility model relates to a beam variable pressure balance system, which comprises a carriage (13), a left oil cylinder, a right oil cylinder and a hydraulic balance system. The hydraulic balance system is positioned at the lower end of a beam and includes a pump, an electromagnetic proportional relief valve (1), a right-angle one-way valve (2), a hydraulic one-way valve (3) and the oil cylinders, which are connected in series via a pipeline. The electromagnetic proportional relief valve (1) is communicated with an overflow valve (4), a one-way throttle valve (6) is communicated with an electromagnetic valve (5) connected with the hydraulic one-way valve (3), and one end of a throttle valve (7) is connected with the hydraulic one-way valve (3). Additionally, an electric controller (8) is further connected to the electromagnetic proportional relief valve (1). The beam variable pressure balance system guarantees no additional affection of spindle precision due to transverse motion of the carriage, and is a r |
