Description

Technical Field

[0001] The invention belongs to the technical field of electromechanical transmission of industrial equipment, and in particular relates to a manual-automatic integrated servo motor. Background Art

[0002] In the current industrial production field, servo actuators are increasingly used, and the structure of servo mechanisms is gradually tending towards integration and miniaturization. In the more mature products on the market, the actuators and control components are often independent of each other. The actuators are integrated inside the equipment and connected to the end effector, and the control components are connected to the host control machine. The controller and the actuator need to be connected to the power supply cable and the control cable, and the host computer and the power supply device need to be connected to the controller by cables, which results in a large number of cables and cumbersome wiring and connection.

[0003] At the same time, the concentration of multiple types of drivers and the arrangement of the host computer make the control box bulky, put forward higher requirements on the installation and heat dissipation of the equipment, and restricted the miniaturization and integration of the servo actuator. Summary of the invention

[0004] In view of this, the present invention provides a manual-automatic integrated servo motor, which can reduce the overall volume and weight of the equipment and the number of connections between the servo and the motor. When the motor fails and cannot be powered on, it can be switched to manual mode, and the operator can control the rotation of the motor through the input shaft at the tail end of the hand-cranked motor.

[0005] A manual-automatic integrated servo motor, comprising a motor, a servo driver, a manual unlocking mechanism, a wiring terminal, a heat sink and a fan;

[0006] The manual unlocking mechanism is installed on the side of the motor. When the motor electronic control fails, the operator controls the movement of the motor by operating the manual unlocking mechanism. The servo drive is installed on the upper surface of the motor through a heat insulation plate to prevent the heat during the rotation of the motor from being transferred to the servo drive and affecting its operation. The terminal is installed on the side of the servo drive; the fan is embedded in the heat sink, and the heat sink is installed above the servo drive through its bottom plate to dissipate heat for the servo drive, so that the servo drive is always kept at a normal temperature.

[0007] Furthermore, four connection ports are arranged on the rear end face of the servo driver, namely, from left to right, a 380V high-voltage power interface, a CAN communication interface A, a CAN communication interface B and a debugging interface. The 380V high-voltage power interface is used to supply power to the integrated servo motor. The CAN communication interface A and the CAN communication interface B are used to connect an external control system to perform motion servo control on the integrated servo motor. The debugging interface is used to perform debugging testing and fault diagnosis on the integrated servo motor. The CAN communication interface A and the CAN communication interface B serve as backups for each other.

[0008] Furthermore, the manual unlocking mechanism includes a hand rod, a connecting mechanism and a protective cover; the protective cover is fixedly connected to the outer casing of the motor, the hand rod is installed inside the protective cover along the axial direction of the motor, one end of the hand rod is located outside the protective cover, one end of the hand rod is connected to one end of the connecting mechanism inside the protective cover, and the other end of the connecting mechanism is connected to the manual input shaft end. When the hand rod is pulled out along the axial direction of the motor, the connecting mechanism completes the unlocking of the motor shaft.

[0009] Further, the motor includes an output shaft end, a bearing, a stator, a rotor, a brake, a housing, an absolute encoder, a manual input shaft end and a protective shell;

[0010] The motor shaft consisting of an output shaft end and a manual input shaft end is supported inside the housing through bearings, the stator and the rotor are installed inside the housing on one side of the output shaft end, the absolute encoder is installed inside the housing on one side of the manual input shaft end, the brake is installed inside the housing behind the absolute encoder, and the part of the manual input shaft end located outside the housing is closed by a protective shell.

[0011] Beneficial effects:

[0012] 1. The integrated servo motor of the present invention integrates the motor, servo controller, manual operation components and other mechanisms into one. Since the power cables and signal cables between the motor and the driver, the power electrical connector plugs and sockets, and the signal cable electrical connector plugs and sockets are omitted, the overall volume and weight of the equipment can be reduced after integration, which is convenient for the installation of the servo motor. In addition, since the motor base in the integrated servo motor has great restrictions on the driver structure, strict limit designs are carried out in the driver circuit board structure design and space layout design, which indirectly reduces the weight of the driver.

[0013] 2. The integrated motor and servo controller of the present invention can reduce the power supply cables and control cable connections between the servo and the motor, reduce the number of wiring, and reduce the interference and difficulty of the motor during disassembly and assembly. In addition, the servo driver is provided with CAN communication interface A and CAN communication interface B, which are mutually backed up by communication interfaces. When a single channel fails, it can switch to another channel for control, thereby improving the reliability of the integrated servo motor.

[0014] 3. The present invention adds a manual input on the side of the motor. When the motor fails and cannot be powered on, it can be switched to manual mode. The operator can control the rotation of the motor by manually cranking the input shaft at the tail end of the motor.

[0015] 4. The integrated motor of the present invention simplifies the previous process of assembling the motor and the driver to only assembling the motor, thereby simplifying the assembly work and operation of the motor. BRIEF DESCRIPTION OF THE DRAWINGS
