The CNC gear rack transmission system is a key component in countless robot applications. It looks very simple, but it can provide an extremely high torque-to-weight ratio and is extremely accurate. So, what are its specific applications and functions in the field of robots?
1. Robot Ground Rail
The robot walking rail-the seventh-axis ground rail robot, as an extension of the industrial robot body, drives the robot to move along the specified route, expands the robot's operating radius, and expands the robot's utilization rate. The rack and pinion are mainly used to achieve the linear motion and precise positioning of the robot along the predetermined track.
Main Function
The CNC gear rack transmission has the characteristics of large transmission force, fast transmission speed, and can be spliced to any length. It is a very efficient transmission method and is usually used in applications with large axial forces. Its advantage is that the drive unit can maintain the same rigidity throughout the entire stroke length; in addition, it has very good economy for applications with a stroke greater than 2 meters, which is very suitable for the seventh axis of the robot.
The same gear rack has different adaptation products for different applications. However, for some robot seventh axis occasions, higher precision of gear rack is required.
Precautions
After the CNC gear rack device is installed, it cannot be put into use immediately. It needs to be adjusted first. The detailed adjustment items include:
- Check whether the gear and rack are assembled correctly;
- Check whether the gear contact is inclined to one end, which needs to be debugged through operation;
- Check whether there is appropriate side clearance;
- The gear and rack need to be lubricated before operation.
2. Industrial Robot Arm
The rack and pinion system is suitable for linear motion such as telescopic, lifting and lateral (or longitudinal) movement of the robot arm. When the rack is fixed and the gear is driven, the rotational motion of the gear is converted into the linear motion of the carriage. The rack and pinion transmission system is very useful for long-distance movement on straight and curved guide rails.
Main Function
CNC gear rack transmission can convert the rotational motion of the motor into the linear motion of the robot arm, so that the robot arm can move along a predetermined path. This linear motion is particularly important for the task of industrial robot arms to operate on a specific trajectory.
Rack and pinion transmission has a large transmission force. When the industrial robot arm is carrying heavy objects or assembling, the rack and pinion can provide stable support to ensure the safety and reliability of operation.
3. Truss Manipulator
Truss robots, also known as truss manipulators, are mostly used in automatic loading and unloading, automatic stacking and other aspects in factory automation.
Main Function
The truss manipulator is driven by a servo motor and driven by gear racks and roller guides. It has stable operation and precise positioning. The use of CNC gear rack transmission system can significantly improve its work efficiency and flexibility, and is widely used in truss manipulators.
4. Six-Axis Robot
Industrial six-axis robots have six active joints. Common industrial six-axis robots include rotation (S axis), lower arm (L axis), upper arm (U axis), wrist rotation (R axis), and wrist swing (B axis). The combination can achieve six degrees of freedom. The six-axis industrial robot completes the flexibility, strength and coverage required for most applications, including welding, handling, spraying, grasping, etc.
Main Function
CNC gear rack can be used as part of the drive system of the six-axis robot, especially in joints or end effectors (such as the telescopic part of the robot arm) that need to achieve linear motion. By converting the rotational motion of the motor into linear motion, the rack and pinion system can effectively drive the robot to perform various tasks.
Summary
CNC gear rack systems have a wide range of applications in robotics, enabling efficient and precise linear motion and control. They play an important role in the fields of robot rails, industrial robotic arms, truss manipulators, etc., and have promoted the development and application of robotics.
