Abstract

The invention discloses a machine tool ram balance device. The machine tool ram balance device comprises a ram, and further comprises a fixed beam; the ram is slidingly connected to connecting plates;a motor is mounted at the top of the ram; an output end of the motor is rotationally connected with a lead screw; a lead screw base is fixed between the connecting plates; a nut is fixed on the leadscrew base; the lead screw extends into the nut, and is screwed with the nut; a nitrogen balance cylinder is mounted on the lead screw base; and a free end of a piston rod of the balance cylinder is fixedly connected with the ram. The machine tool ram balance device has the following advantages: the balance cylinder is fixed on the same sides of a driving motor and the lead screw; when the ram moves down, the piston rod is driven to move down to counteract the weight of the ram; meanwhile, the balance cylinder is provided; and the straight torque is formed between a balance oil cylinder and the driving motor, so that the linearity change in the ram descending process is low, and the machining precision is effectively improved.

Description

technical field [0001] The invention belongs to the technical field of numerical control machine tools, in particular to a machine tool ram balancing device. Background technique [0002] In the current processing machine tools, especially large-scale processing machine tools, in order to improve the dynamic response of the machine tool, a nitrogen balance system is usually added to the machine tool ram to offset the weight of the ram, reducing the motor load and improving the dynamic response of the machine tool. The nitrogen balance system The nitrogen balance cylinder is usually set on the opposite side of the ram driving device, but during the ram descending process, the bending moment of the nitrogen balance cylinder and the driving force stroke changes greatly in the straightness of the ram's full stroke, which affects the machining accuracy. Contents of the invention [0003] In order to solve the problem in the prior art that the nitrogen balance system affects the...
