Square slide sleeper counter weight mechanism for upright lathe

Abstract

The invention discloses a square slide sleeper counter weight mechanism for an upright lathe. The square slide sleeper counter weight mechanism for the upright lathe comprises a vertically arranged square slide sleeper for the upright lathe and a gland at the upper end of the square slide sleeper; the square slide sleeper counter weight mechanism is characterized by also comprising an oil cylinder; the oil cylinder is arranged in the square slide sleeper and the cylinder body of the oil cylinder is connected with the square slide sleeper; a piston rod of the oil cylinder is connected with the gland at the upper end of the square slide sleeper; the piston rod of the oil cylinder is provided with an inner hole communicated with a rod cavity of the oil cylinder; the square slide sleeper counter weight mechanism also comprises a hydraulic system comprising an oil tank and a hydraulic pump; the outlet of the hydraulic pump is connected with a check valve and a reduction valve in sequence by an oil path and is then connected with the inner hole of the piston rod of the oil cylinder; one energy accumulator is arranged on the oil path between the hydraulic pump and the check valve; a first overflow valve overflowing to an oil tank is arranged on the pipeline, connected with the piston rod of the oil cylinder, of the reduction valve. The work stability of the square slide sleeper can be improved by the counter weight mechanism, the assembly is convenient and the weight can be precisely adjusted according to the change of a cutting force.

Description

technical field [0001] The invention belongs to the field of square ram counterweights of vertical lathes, specifically a square ram counterweight mechanism with simple structure and freely controllable counterweight range, which solves the problems caused by the poor stability of square rams during work. Excessive load and severe wear of the lead screw. Background technique [0002] In the vertical lathe, the stable performance of the working condition of the vertically installed square ram is very important. If the square ram does not work smoothly, it will not only affect the machining accuracy, but also appear due to the excessive load of the motor and the serious wear of the screw. The problem of reduced mechanical life. In the prior art, a counterweight is usually used for the stability of the vertically sliding parts, and a lead pouring weight is generally used as the counterweight. However, the problems in this method are as follows: (1) The use of a heavy hammer c...
