Embodiment Construction

[0012] Below in conjunction with accompanying drawing, the present invention is described in detail:

[0013] The electromechanical device of the arc indexing cam mechanism: the motor 2 is connected to the arc indexing cam box 4 through the coupling 3, the motor 2 and the arc indexing cam box 4 are fixed on the base 5, and the position encoder [1] is installed on the motor of the tail. The controller 6 is connected with the motor and the encoder.

[0014] Controller 6 is composed of microprocessor TMS320F240, program memory, interface circuit, Hall current sensor, power driver, IPM power module and control software. The controller can input or modify the control scheme through off-line programming or solidified program.

[0015] The controller 6 obtains the rotation angle of the motor 2 and the three-phase current information from the position encoder and the current sensor in real time, and uses the sliding mode disturbance observation technology to obtain the compensation c...

Abstract

The present invention relates to one kind of electromechanical unit and control method for arc indexing cam mechanism. The electromechanical unit consists of mainly motor and its controller, positioncoder, arc indexing cam box, coupling and base. By means of running dynamic torque disturbance compensating algorithm, the motor control is compensated actively to reduce the effect of cam mechanism caused by load change. The present invention can raise the positioning precision of arc indexing cam mechanism and reduce the impact and noise of the arc indexing can mechanism produced in running.

Description

1. Technical field [0001] The invention belongs to the field of electromechanical integration, and in particular relates to an electromechanical device and a control method for an arcuate indexing cam mechanism. 2. Background technology [0002] Arc-shaped indexing cam mechanism is a kind of intermittent motion mechanism. Due to its acceleration and deceleration movement rules, manufacturing and assembly errors, and mechanical characteristics of the motor, it forms a large periodic load, which seriously affects the positioning accuracy of the actuator. There are also serious shocks and vibrations in the process. How to improve the transmission accuracy of the whole mechanism has become the research focus and difficulty in the research field of space arc indexing cam mechanism. At present, the research on arc index cam mechanism mainly focuses The shape and the mechanical transmission part of the cam mechanism are used to achieve the purpose of optimizing the transmission ac...
