Abstract

The invention discloses a device for controlling stroke of a worktable of a machine tool and a controlling method thereof. The device comprises a PLC, a photoelectric encoder, a touch screen and a speed governor of a direct current motor, wherein the PLC is used as a control logic device, a mechanical axis of the photoelectric encoder is coaxial with a worm for driving the worktable so as to acquire operation parameters of the worktable in real time; the output end of the photoelectric encoder is connected with a port of the input end of a high-speed counter of the PLC; the touch screen is connected with a serial port of the PLC and is used as a main action instruction input interface and a display interface of the worktable; and the speed governor of the direct current motor is connected with the output port of the PLC and is used for receiving a PLC control command and driving a stroke motor of the worktable. The invention provides the device for controlling the stroke of the worktable, which uses few elements, is convenient to adjust the largest stroke of the worktable and has high reliability and realizes the contactless reversing of the worktable.

Description

(1) Technical field [0001] The invention belongs to the technical field of machine tool control, and relates to a device for controlling the travel of a machine tool workbench, specifically applied to a machine tool with reciprocating motion of the workbench to control the working stroke of the workbench. The invention also relates to a control method of the control device. (2) Background technology [0002] At present, the stroke control technology of machine tool table is mostly based on combination switch control, proximity switch control or double synchro control. Among them, the combined switch control system relies on the travel switch for the stroke control of the workbench, but the workbench speed of the machine tool is relatively fast. The reversing speed does not exceed 250mm / min; another point is that the work of the machine tool is too common and heavy, and the worktable of the gantry planer is automatically up to 4.5 tons. Mechanical damage, and the replacemen...
