What is A Precision Indexing Table
Widely applied in CNC machining, assembly, testing, and other domains, the precision indexing table is a tool for high-precision indexing and positioning control. Usually, its construction calls for a driving engine, a dividing plate, a dividing mechanism, and a supporting framework. Driven by a motor, the working concept is to rotate the dividing plate through a built-in dividing mechanism (such as gears, cams, etc.). Cooperation with the built-in dividing mechanism will help to attain exact intermittent rotation and positioning. Perfect machining and automated manufacturing lines call for the high-precision, low-backlash indexing control the precision indexing table offers to guarantee that the workpiece may be precisely positioned every time it turns.
The two sizes, 70DS and 80DS, are currently the most popular, cost-effective, and suitable for the current mainstream automated production line equipment. Widely used in packaging, pharmaceutical, electronics, precision machinery parts assembly, and other automation industries. We also have 25DS, 32DS, 45DS, 60DS, 70DS, 80DS, 110DS, 140DS specifications and support customization.
Simple framework for precision indexing tables
1. System of drives
Usually including motor, reducer, and drive shaft, the drive system forms the foundation of the precision indexing table. The reducer turns the fast rotation of the drive motor into the necessary low-speed high-torque output, therefore driving the indexing plate to rotate exactly.
2. Indexing in a plate
Usually the major functioning component of the indexing table, the indexing plate is on which the workpiece or tool is set. The indexing plate could be circular and stops precisely after every rotation of a given angle using a suitable indexing mechanism. The indexing plate's rotation can be divided and changed as necessary and achieves great-precision placement.
3. Indexing mechanism
Key element of the precision indexing table, the indexing mechanism transforms drive system rotation into exact indexing action. Typical systems of indexing consist in:
Gear indexing mechanism: Perfect intermittent rotation is obtained by means of gearbox and gearbox interaction, appropriate for uses demanding high torque output.
Suitable for applications needing highly exact and sophisticated indexing, the meshing between the cam and the roller controls the rotation.
Fine indexing is accomplished with spiral gears, appropriate for situations requiring great accuracy and heavy load demands.
4. Framework of support
The indexing table has steady support from the support structure, therefore guaranteeing the stiffness and stability of the whole system. Usually built with high-strength metal components, it guarantees longevity and bearing capacity.
5. System for positioning
The indexing table is kept stably every time it rotates to the designated location by means of a positioning system. Typical systems of positioning consist in:
The mechanical locking device fixes the position when the indexing table reaches the specified angle, therefore guaranteeing the indexing accuracy.
High-precision sensors or encoders can detect the location of the indexing disc in real time and offer feedback via digital signals, therefore obtaining more exact control.
6. System of control
Usually featuring digital control systems capable of precisely regulating the rotation angle and indexing time, modern precision indexing tables By use of digital control techniques, one may set the indexing angle, speed and operating mode, so enhancing the precision and adaptability of operation.
