Problems solved by technology

The rotation and positioning of the rotary table are driven by a stepping motor. After the rotary table is positioned, there is a delay time for stopping the rotation. The existing stepping motor driver has no delay function, and the price is relatively high.

Embodiment Construction

[0013] The specific embodiment of the present invention will now be described in conjunction with the accompanying drawings.

[0014] Described driving circuit is made up of counting integrated block IC1, NOT gate IC8, AND gate IC7, or gate IC2-IC5; The model of counting integrated block IC1 is CD4017, and it has 10 decoding output terminals and is pin Q0-Q9, The state of each output terminal corresponds to the number of clock pulses. At any time, only one output of Q0-Q9 is high level, and the others are low level; the pin R of the counting integrated block IC1 is the clearing terminal. When the pin R=1, the pins Q0-Q9 are all zero, the pin CP is the clock pulse input terminal, and the rising edge of the pulse triggers counting, and the pin / EN of the counting integrated block IC1 is the enable and disable terminal, and the high level prohibits Counting, low level allows counting.

[0015] The pin R of the counting integrated block IC1, the NOT gate IC8, and the AND gate IC7...

Abstract

The invention discloses a control device for a revolving table. The control device comprises a drive circuit for rotating a step motor and a control circuit for controlling a rotation angle of the step motor, wherein the drive circuit is formed by a CD4017 counting integrated block and a CD4075 OR gate; the drive control circuit is formed by a frequency divider and a delayer; the frequency divider controls the rotation angle of the step motor at each time; and the delayer controls a time interval between the adjacent rotation times of the step motor. The control device has the characteristic that an input signal of the delayer in the control circuit is an output signal of the frequency divider, so that the structure of the delayer can be simplified.

Description

technical field [0001] The invention relates to a control device for a rotary worktable, which drives a stepping motor for rotating the worktable and a control device for the stepping motor, and the control device is composed of electronic components. Background technique [0002] For some parts processed in a single process, the processing steps are workpiece loading, cutting and unloading. In order to improve work efficiency, a rotary worktable is adopted. The fixtures for clamping parts are symmetrically installed on the workbench. The side fixture can face a cutting processing device, the workbench can rotate and the cutting processing device is fixed, and the workpiece can be loaded and unloaded during cutting processing, so that the processing parts and loading and unloading parts can be carried out synchronously. The rotation and positioning of the rotary table are driven by stepper motors. After the rotary table is positioned, there is a delay time for stopping the r...
