Problems solved by technology

However, when the broaching machine is working, due to the characteristics of the broach structure, the broaching force will have a step and a periodic change in the size of the broaching force due to the different tooth positions of the broach, which will aggravate the vibration and flutter of the machine tool. Product quality has a big impact, but also has a lot of impact on machine tool and pull life

Abstract

The invention discloses a variable-load broacher counterweight system, which comprises a servo motor, a counterweight cylinder, a digital signal processor and an electrical servo valve, wherein the servo motor drives a broacher worktable by the aid of a lead screw, and the counterweight cylinder is connected with the broacher worktable through a connecting rod. An air source is connected with the electrical servo valve, the servo motor is connected with the digital signal processor through an ammeter, the digital signal processor is connected with the electrical servo valve and controls openness of the electrical servo valve by outputting voltage signals, the electrical servo valve is connected with the counterweight cylinder, and a synchronous mechanism is arranged between the servo motor and the counterweight cylinder. The variable-load broacher counterweight system has the advantages that fluctuation of the current of the servo motor is continuously monitored, and when the detected current of the servo motor steps, the thrust of the counterweight cylinder is timely adjusted by a pneumatic counterweight device to balance load fluctuation caused by tension change and to suppress vibration during machining.

Description

technical field [0001] The invention relates to a broaching machine counterweight system, in particular to a variable load broaching machine counterweight system and a control method. Background technique [0002] A broaching machine is a machine tool that uses a broach to process the inner and outer forming surfaces of various workpieces. When the servo-driven broaching machine is working, the servo motor drives the broaching table to move through the roller screw, and the broaching table moves vertically along the broaching column. In the no-load state, due to the gravity of the worktable, the driving force required by the motor is different when the broaching worktable is rising and falling. In order to make the motor have the same driving force in the process of rising or falling, a counterweight is usually used Law. The traditional counterweight method uses a counterweight hammer or a hydraulic counterweight system, which only solves the basic driving force problem. ...
