specific Embodiment

[0054] Such as figure 2 As shown, it is a kind of experimental machine clamp clamping device provided in this embodiment, including clamping machine clamp 1 and machine clamp 2, the clamping transmission is gear transmission, and the clamping drive motor is a DC brushed motor . The photoelectric switch is set inside the machine clamp A or machine clamp B, and can measure the distance between the two machine clamps.

[0055] The system control process starts from the Arduino control board. The Arduino control board reads the information of the DC motor encoder and measures the current position of the DC motor. The photoelectric switch senses whether the clamp finger of the induction machine driven by the DC motor will collide with other mechanisms, and then DC motor position zero correction. The fixture control system software is set in the Arduino control board, which is converted into the moving distance of the DC motor according to the fixture command sent by the computer...

Abstract

The invention provides a controller system for sensing the clamping of a machine clamp and a control method thereof. The system comprises an Arduino microcontroller, a motor driver, an encoder, a photoelectric switch and a current transmitter. The motor driver drives a clamping motor. The encoder is installed on the clamping motor. The photoelectric switch is installed on a clamping mechanism andthe distance between clamp forceps is detected. The current transmitter detects the magnitude of the current of the clamping motor. The Arduino microcontroller receives the rotating speed and positioninformation of the clamping motor detected by the encoder, and also receives the information of the photoelectric switch and the current transmitter. The rotation speed of the clamping motor is finally controlled by controlling the motor driver. The method adopts the fuzzy control algorithm, wherein the material clamping magnitude of the machine clamp can be controlled based on the current changeof a current sensor. The resistance can be generated when the machine clamp is clamped to get in contact with an object, so that the current of the motor can be changed based on the resistance. Therefore, the magnitude of the motor can be controlled. The opening and closing speed and the precision of the clamping of the mechanical arm type machine clamp are improved. The overall production capacity is improved.

Description

technical field [0001] The invention relates to the technical field of clamping control of machine tongs, in particular to an induction machine tongs clamping controller system and control method. Background technique [0002] A bench vise is a general fixture used to hold workpieces. Installed on the workbench, it is used to clamp and stabilize the workpiece. It is an essential tool in the fitter workshop. The turntable-type pliers can rotate to make the workpiece rotate to a suitable working position. Its use cannot meet the needs of the intelligent age. The development of industrial robotic arms is a mechatronic device that anthropomorphizes the functions of the human arm, wrist and hand. A mechatronic device that simulates the functions of the human arm, wrist, and hand; it can move any object or tool according to the time-varying requirements of the spatial posture (position and posture), so as to complete the operation requirements of an industrial production. Such...
