What do the parameters of the precision electric sliding table mean?
The precision electric sliding table is a linear drive mechanism widely used in the automation technology industry. It is commonly applied in CNC lathes, automatic machines, and robots, generally driven by stepper motors or servo motors. It achieves parallel movement of rollers through a transmission system matched with high-precision ball screws or synchronous belts and linear guides. In the industrial field, electric sliding tables require good rigidity and repeatability, and their durability, energy efficiency, and load capacity are the main parameters to consider in design and application.
Precision sliding tables have also become single-axis robotic arms, parallel motion modules, linear modules, etc.
According to different industrial production requirements, the precision levels of electric sliding tables are divided into many grades. Factors affecting the precision grade of electric sliding tables include: the torque performance of the driving motor, the load characteristics and precision of the linear guide, and the precision grade of the ball screw.
The main features of precision electric sliding tables can be represented by three basic parameters:
Precision: Different fields have different precision levels for precision electric sliding tables, so there are no actual requirements for the measurement precision of electric sliding tables. Precision can be classified according to large and medium-sized machinery and small machine tools. Generally, the precision of large CNC lathes is around 1 meter 1 thread, while the precision level of large, medium, and small machinery is generally higher than 0.1mm.
Speed: Generally, the speed of precision electric sliding tables is below the standard deviation. Since speed is critical, there is a load risk in electric sliding tables. At the same time, if only speed is required during the production process, precision will also be affected and reduced.
Load: Load is one of the basic elements that endanger the precision and speed of electric sliding tables. Stroke arrangement: A reasonable stroke arrangement refers to the effective path length that the rollers in the electric sliding table can roll. The longer the duration of the electric sliding table, the greater the adverse impact of the load.
Introduction to the application of precision electric sliding tables
Under the condition that basic functions such as load and speed remain unchanged, the integration of functions and the miniaturization of sliding table structures will become increasingly popular. Currently, we have reached a technical level in precision sliding tables, and we can provide customers with reasonably priced dedicated electric sliding table modules. We have also developed products suitable for general environments and harsh working conditions. Automation, as a long-term endeavor, will become increasingly intelligent, further liberating productivity and manpower. As a basic component of precision sliding table modules, it will also receive the development and progress it deserves! The precision sliding table is a device that obtains driving force through ultrasonic stretching vibration, and then drives the motor rotor through sliding friction.
The microscopic structure of precision electric sliding tables can be roughly divided into three categories,
1. Inductive type, with a basic structure similar to that of general motors, including motor stator, motor rotor, synchronous motor windings, brushes, and other components, but with a particularly compact structure.
2. Generally, there are two types of units: combinations of various micro motors, and combinations of micro motors with electronic circuits, such as the combination of DC motors with inductors, and parallel motors in the X and Y directions. 3. Non-inductive type, with a design structure similar to the inductive type, such as rotating the product into a cylindrical shape. Although water products are made into square shapes, the internal structure is quite different due to different principles.
Alright, that's all for today. Thank you all for watching.
