Description

Technical Field

[0001] This utility model belongs to the field of servo drive equipment technology, specifically relating to a servo drive integrated machine structure. Background Technology

[0002] In modern industrial production, many devices have increasingly higher space requirements. Currently, the industry's servo control system consists of a servo driver and a motor. The driver supplies power to the motor and collects the motor's status through wiring. However, since the driver and motor are separate, a large number of wires are required for connection, which leads to complex wiring, increased failure rate, and also occupies a lot of space, causing many inconveniences to operation. Summary of the Invention

[0003] The purpose of this invention is to address the above-mentioned problems by providing a servo drive integrated machine structure.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: a servo drive integrated machine structure, including a motor housing and a motor body with a motor shaft rotatably disposed within the motor housing. Both ends of the motor shaft pass through the ends of the motor housing, with one end serving as the output end. A circuit board mounting housing is connected to the end of the motor housing furthest from the output end. The circuit board mounting housing contains, from the end closest to the motor shaft to the end furthest from the motor shaft, an encoder and power board with encoder and driver components, a control circuit board with control circuitry, and a communication board with several connection sockets. The end of the circuit board mounting housing furthest from the motor housing has several socket holes, and each connection socket is inserted into one of these socket holes. The motor body is disposed within the motor housing, and the encoder and power board, control circuit board, and communication board are all mounted within the circuit board mounting housing. The encoder and power board are connected to the motor body, reducing the number of components and wiring costs, simplifying the installation and debugging process, and lowering labor and time costs. Simultaneously, the encoder and power board, control circuit board, and communication board provide precise position control, speed control, and torque control, thereby improving production efficiency and product quality.

[0005] In the aforementioned servo drive integrated machine structure, the encoder and power board, control circuit board, and communication board are all the same size and rectangular in shape. Using three different circuit boards reduces the probability of failure and improves reliability and stability.

[0006] In the aforementioned servo drive integrated machine structure, the encoder and power board, control circuit board, and communication board are arranged in parallel with equal spacing. The encoder and power board and the control circuit board, as well as the control circuit board and the communication board, are connected and electrically communicate with each other via male and female connectors. This reduces the number of components and wiring costs, resulting in a more compact structure and smaller size.

[0007] In the aforementioned servo drive integrated machine structure, the motor housing is a rectangular cylindrical structure with open ends. One end of the motor housing is provided with a front cover and the other end is provided with a rear cover. One end of the motor shaft passes through the front cover to form an output end and the other end passes through the rear cover.

[0008] In the aforementioned servo drive integrated machine structure, the circuit board mounting housing is a rectangular cylindrical structure that matches the motor housing. The circuit board mounting housing is closed at one end near the motor housing and open at the other end. The closed end of the circuit board mounting housing has a sensing hole corresponding to the motor shaft. The circuit board mounting housing and the motor housing are coaxially arranged, and the end of the circuit board mounting housing away from the motor housing is provided with a housing end cap.

[0009] In the aforementioned servo drive integrated machine structure, the two opposite corners of the front cover are respectively connected to the two opposite corners of one end of the motor housing through front cover connecting bolts, the two opposite corners of the rear cover are respectively connected to the two opposite corners of the other end of the motor housing through rear cover connecting bolts, the two opposite corners of the housing end cover are respectively connected to the circuit board mounting housing through end cover connecting bolts, and the end cover connecting bolts pass through the circuit board mounting housing and are connected to the two opposite corners of the motor housing.

[0010] In the aforementioned servo drive integrated machine structure, the front cover connecting bolts and rear cover connecting bolts are staggered and pass through different diagonal points on the motor housing. Similarly, the rear cover connecting bolts and end cover connecting bolts are staggered and pass through different diagonal points on the motor housing near the circuit board mounting housing. Furthermore, the two diagonal points on the motor housing near the circuit board mounting housing have grooves for accommodating the bolt heads of the rear cover connecting bolts. This groove design avoids unevenness when the motor housing and circuit board mounting housing are connected, improving the stability of the connection.

[0011] In the aforementioned servo drive integrated structure, the encoder and power board, control circuit board, and communication board each have corresponding diagonal arc-shaped grooves. Separating cylinders are provided between the arc-shaped grooves of the encoder and power board and the control circuit board, and between the arc-shaped grooves of the control circuit board and the communication board. The outer side of each separating cylinder extends beyond the arc-shaped groove, and an axially extending arc-shaped groove matching the separating cylinder is located on the circumferential inner side of the circuit board mounting housing at a diagonal angle. The end cap connecting bolts pass through each separating cylinder. The separating cylinders ensure sufficient space between the encoder and power board, control circuit board, and communication board, while also facilitating the passage of the end cap connecting bolts for a secure fixation effect.

[0012] In the aforementioned servo drive integrated machine structure, the socket hole is formed on the outer casing end cover, and the connection socket does not extend beyond the outer side of the outer casing end cover.

[0013] In the aforementioned servo drive integrated machine structure, the communication board is an EtherCAT communication protocol circuit board, and the connection socket is an EtherCAT interface. The EtherCAT communication protocol circuit board features high-speed real-time performance and the high precision and fast response of the servo motors, enabling precise coordination of the actions of each servo motor to achieve high-speed, high-precision machining of complex trajectories.

[0014] Compared with existing technologies, the advantages of this utility model are:

[0015] 1. This device mounts the motor body inside the motor housing, and mounts the encoder, power board, control circuit board, and communication board inside the circuit board mounting housing. The motor housing is connected to the circuit board mounting housing, and the encoder and power board are connected to the motor body. This reduces the number of connection lines, avoids complex wiring, and makes the structure more compact.

[0016] 2. The device has three types of circuit boards installed inside the circuit board mounting housing. The three types of circuit boards are connected by male and female connectors, which can reduce the probability of failure, improve the overall reliability and stability, and enhance precise control, thereby ensuring production efficiency and product quality.

[0017] 3. The device uses an EtherCAT communication protocol circuit board, which can achieve high-performance operation control, improve high synchronization accuracy and precise control, while reducing wiring costs, wiring complexity and space occupation, and also reducing the number of controllers required, thus reducing hardware costs.
