Problems solved by technology
The precision four-column cutting machine relies on this crankshaft-connecting rod mechanism to achieve precise balance during cutting, but this mechanism has the disadvantages of large structural size and high processing accuracy requirements. With the increase in the tonnage of the precision four-column cutting machine, not only the material cost will increase sharply , the processing difficulty of the parts is also increasing

The invention relates to a balance mechanism for a precision four-columns cutting machine, which comprises a guide sleeve, a guide column, a piston, an end cover and sealing pieces, and further comprises a balance valve. The guide sleeve is fixed on a machine body; the guide column penetrates through the guide sleeve and the end cover; the piston is arranged in the guide sleeve and fixed on the guide column; the end cover and the guide sleeve are in threaded connection; the guide sleeve and the piston are in sliding match; the piston is provided with grooves and the sealing piece; the guide sleeve and the end cover are respectively matched with the guide column in a sliding way; and the matching position is provided with grooves and the sealing piece. The balance mechanism is distributed on four upright columns of the precision four-column cutting machine, the mechanisms form synchronous serial connection by oil pipes, the balance valve is arranged on the closed oil pipes, and the balance is automatically achieved through a hydraulic system with no need of a crank connecting bar balance mechanism with a huge structure, thus the cost is reduced.
Description
technical field [0001] The invention relates to a precision four-column cutting machine in the cutting machinery industry, in particular to a balance mechanism of the precision four-column cutting machine. Background technique [0002] At present, the balance mechanism of the precision four-column cutting machine includes connecting rods, left crankshaft, right crankshaft, left swing rod, right swing rod, left oil cylinder, and right oil cylinder. The two ends of the connecting rod and the left and right crankshafts are connected by pins. The crankshaft is connected with the output shafts of the left and right oil cylinders respectively by the left and right swing rods. The precision four-column cutting machine relies on this crankshaft-connecting rod mechanism to achieve precise balance during cutting, but this mechanism has the disadvantages of large structural size and high processing accuracy requirements. With the increase in the tonnage of the precision four-column cut...
