Abstract

A vertical lathe worktable control system comprises a cabinet body, a main circuit, an auxiliary control circuit and a braking circuit, wherein the main circuit, the auxiliary control circuit and the braking circuit are installed in the cabinet body. In the main circuit, alternating-current three-phase four-wire is connected with a power source input end of transducer VVVF through a combination switch QF, an input power source filter and an alternating-current contactor KM1. The output of main circuit is connected with a main electric motor through an output power source filter. A PLC programmable controller is the core of auxiliary control circuit. A braking unit comprises a transducer braking mechanism, a braking resistor box, a first transducer frequency setting potentiometer, a second transducer frequency setting potentiometer, a second transducer inching frequency setting potentiometer, a transducer frequency meter and an electromagnetic brake. The transducer VVVF is connected with the transducer braking mechanism. The vertical lathe worktable control system of the invention has the advantages of simple structure, strong reliability, convenient speed adjustment, energy consumption saving, increased operation speed and increased cutting efficiency. The vertical lathe worktable control system of the invention can be widely used on the cutting mechanical device.

Description

technical field [0001] The invention relates to a control system, in particular to a vertical lathe workbench control system. Background technique [0002] At present, most of the control methods of the vertical lathe worktable are driven by the DC generator set to rotate the DC motor, and the rotation number is set through the speed regulating resistor of the auxiliary control circuit, and some use the thyristor DC governor to directly adjust the rotation of the DC motor. The conduction angle of the silicon controlled rectifier is realized by the auxiliary control circuit, that is, the silicon controlled silicon trigger circuit. However, with the improvement of the technical level, these traditional control methods are increasingly showing its shortcomings and deficiencies, such as high energy consumption, high failure rate, large maintenance amount, long maintenance cycle, complicated speed regulation methods, and high-order harmonics generated It interferes with the powe...
