Embodiment 1

[0045] An embodiment of the present invention is as follows:

[0046] as attached figure 1 shown. The driving device of the electromagnetic automatic balancing actuator of the present application can only be equipped with one driving control board 4 and the supporting interface unit 2, and can be used with an electromagnetic automatic balancing actuator with a single counterweight plate.

[0047] The installation sequence of the drive unit is as follows:

[0048] First place the drive control board 4 on the support column inside the housing 3, align the interface unit 2 with the rectangular hole on the front side of the housing 3, and then tighten it with a copper column of the same length. Put the upper cover 1 into the groove on the upper part of the housing 3, and use bolts to fix the upper cover and the copper pillar together. Finally, use bolts to fix the driving device on the casing as a whole, and then connect all the cables firmly, so far the installation of the dri...

Embodiment 2

[0050] Another embodiment of the present invention is as follows:

[0051] as attached figure 1 shown. The driving device of the electromagnetic automatic balancing actuator of the present application can be installed with two driving control boards 4 and the supporting interface unit 2, and can be used with the electromagnetic automatic balancing actuator with double counterweight plates. The installation sequence of the drive unit is as follows:

[0052] First place the drive control board 4 on the support column inside the housing 3, align the interface unit 2 with the rectangular hole on the front side of the housing 3, and then use the same length of copper column to tighten it; then install the next drive control board 4. Place it on the copper column, align the interface unit 2 with the rectangular hole on the front side of the housing 3 and fix the control board with a short copper column, and finally put the upper cover 1 into the groove on the upper part of the hou...

Abstract

The invention discloses an embedded pulse generator for propeller automatic balance. The embedded pulse generator comprises a shell, an upper cover matched with the shell, a drive control panel arranged in the shell and the upper cover and used for driving an electromagnetic automatic balancing device, and an interface unit located on one or more sides of the drive control panel and connected withthe drive control panel, wherein the interface unit comprises a power interface unit, an output interface unit and a communication interface unit. Components of the driving device are integrated andoptimized, the automatic balancing algorithm is embedded into a chip, original relay wiring is replaced by a logic circuit, the reaction speed of the driving device is greatly improved, the size and the weight are reduced, and installation and debugging are convenient. The shapes of the interfaces of the driving device are different from each other, so that the condition of equipment damage causedby incorrect insertion by an operator is prevented.

Description

technical field [0001] The invention relates to an embedded pulse generating device for a propeller automatic balancing driver, which can generate stable and accurate positive and negative alternating pulses, and is used for the directional movement of the counterweight in the electromagnetic automatic balancing head, belonging to the vibration suppression and automation of rotating machinery field. Background technique [0002] There are many reasons for vibration failures of rotating machinery, and 70%-80% of vibration failures are caused by mass imbalance. The automatic balancing technology can adjust the mass distribution of the rotor in real time to suppress unbalanced vibration without stopping the rotating machine. Among them, the electromagnetic-driven double counterweight automatic balancing system (hereinafter referred to as the automatic balancing system) is developing rapidly. Currently, it is used in machine tools, turboprops There are industrial application re...
