Production of Reinforced Hollow Rotary Tables:

Rotary Indexing Tables
Production of Large Aperture Hollow Rotary Tables:

Rotary Indexing Tables or Hollow rotary platform reducer is a popular automation device in recent years. There are many names in the market, such as hollow rotary table, hollow rotary platform reducer, high-precision hollow screw platform reducer, stepping rotary platform, servo rotary table, rotator and steering gear, which refer to different names of a product.

Rotary Indexing Tables or Hollow rotating platform is a revolutionary new product. It is used in a variety of rotary motion occasions. It can replace DD motor and cam splitter. It integrates high efficiency, high precision, high rigidity and high cost performance. It is a revolutionary product in rotary motion mechanism. Achieve a balance between the two. The repeated positioning accuracy of Rotary Indexing Tablesis ≤ 10 seconds. Motor is easy to prepare and the load,stable. It can be divided at any angle with AC servo motor or stepping motor, which can not only meet the digital control that the divider cannot achieve, but also comparable to DD motor. It can greatly reduce the cost.

What are the advantages of Rotary Indexing Tables or hollow rotating platform?
1. Elastic matching connection
Rotary Indexing Tables can be compatible with servo or stepper motors of various brands. Connection between the input end and the motor adopts the collet type locking mechanism, and the dynamic balance analysis is carried out to ensure the concentricity and balance of the bonding interface and the power transmission of zero back clearance at the input speed.

2. High precision positioning
Repeat positioning accuracy ± 10 sec,High precision positioning without backlash. Realize the positioning of inertial load in a short time

3. High rigidity, two kinds of bearings are optional
Ball bearings can be used in applications with small axial load.
Where radial and axial loads need to be carried at the same time, high-precision cross ball bearings can be selected. This bearing has the advantages of small volume, compact structure and high rigidity.
The rotary table of Rotary Indexing Tables is supported by a set of precision cross roller bearings. The rollers in the bearing are staggered at 90 degrees, and the roller diameter is slightly larger than the raceway size between the inner and outer rings of the bearing, so that there is a preload between the inner and outer rings of the cross roller bearing and the rollers. Therefore, the Rotary Indexing Tables supported by the bearing can bear various moments such as radial, axial and overturning, and its rigidity is more than 5 times that of the traditional bearing.

4. Reduce design time Shorten delivery time
The output platform can be directly installed on the workbench or manipulator of the equipment. Compared with the use of belt, pulley and other mechanism parts, it can reduce the time and cost of mechanism design, part allocation and belt tension adjustment, save the design time and help shorten the delivery time.

5. Convenience
The large-diameter hollow hole (penetration) can be used on the surrounding complex wiring piping, which can simplify the equipment design.

6. High torque, low backlash
The reduction mechanism adopts spiral gear design, and the tooth profile meshing is more than twice that of ordinary spur gears. Rotary Indexing Tables have  the characteristics of smooth operation, low noise, high output torque and low back clearance.
If the rotating platform adopts planetary deceleration to increase the output torque, the deceleration ratio is from 1 to 600, and the output torque range is large, which can meet various torque requirements.

7. High output and high rigidity
Standard type output platform bearings use radial and axial bearings to achieve high load and high rigidity.
< output > maximum allowable inertia 200N ▪ m
< rigidity > maximum allowable axial load 500N ▪ m
The larger the model, the greater the allowable inertia, and the smaller the deformation displacement relative to the load inertia.

8. High rigidity
When there is 10kg working object 160mm away from the central part of the platform, the pipe weight is 15.7 n ▪ m. 9.8kgxgm/s 2×0. 16m=15.7 N ▪ m

9. High precision machining
The rotating disc body of Rotary Indexing Tables is made of aluminum alloy and processed by high-precision CNC and testing equipment to ensure the precision of each part. After carburizing heat treatment and gear grinding, the precision of the gear is within din6, and the hardness of the tooth surface is hrc58 ~ 60 degrees.

Why Rotary Indexing Tables Should Be a Key Part of Your Manufacturing Strategy

Introduction
If you’re familiar with the manufacturing process, you know that there are a number of steps involved – from design and development to prototyping and production. In order to streamline the process and increase efficiency, manufacturers rely on a variety of machines and tools.
One of the most essential pieces of equipment in any manufacturing facility is the rotary indexing table. Rotary indexing tables are versatile tools that can be used for a variety of applications, such as welding, fabricating, and assembly.
In this article, we’ll take a closer look at rotary indexing tables and explain why they should be a key part of your manufacturing strategy.

What are rotary indexing tables?

A rotary indexing table is a type of equipment that is used in the machining and manufacturing processes. It is capable of precision indexing and positioning of components, tools, and workpieces on a rotating platform. The table’s rotating platform is driven by an intermediary gear motor. The gear motor can be customized depending on the specific application and needs. The gear motor’s speed is typically between 6 to 35 rpm, allowing for precise and accurate positioning of components. Rotary indexing tables also have a variety of optional features, such as a servo motor for higher precision, a built-in pneumatically driven vacuum chuck for quick part loading, or a tiltable table for easier cut-off operations.

The benefits of rotary indexing tables

There are numerous benefits to using a rotary indexing table in your manufacturing process. The most obvious benefit is increased speed and efficiency. As the table rotates, it enables quick indexing and positioning of components, which significantly reduces setup time. This increases production output and improves the overall efficiency of your manufacturing operations. Rotary indexing tables also provide improved accuracy and repeatability. By indexing each part, the table is able to very quickly and precisely locate components, which helps to minimize errors and improve product quality. Additionally, with the right gear motor, the tables can provide repeatable accuracy of indexing positions. The table is also able to quickly move smaller components without damaging them, allowing for increased productivity. Finally, rotary indexing tables are versatile and can be used with a variety of manufacturing processes, such as welding, routing, and cutting.

How to incorporate rotary indexing tables into your manufacturing strategy

In order to get the most out of a rotary indexing table, you need to incorporate it into your manufacturing strategy. First, you should select the best table for your specific application. Consider factors such as size, number of faces, speed, and repeatability to ensure you get the most suitable table. Then, you should determine how the table will be used. Consider how frequently it will be used and the types of components that will be indexed. Additionally, you should decide if any additional features are necessary (such as a servo motor, pneumatically driven chuck, or tiltable table). Once you have selected the ideal table for your application, the next step is to properly install and set up the table. This will ensure that it is properly aligned and will work optimally for your manufacturing process. Finally, you should ensure that proper maintenance is performed to keep the table running smoothly and efficiently.

The bottom line

Rotary indexing tables are essential pieces of equipment in any manufacturing facility. They provide a number of benefits, such as improved efficiency, accuracy, and repeatability. As such, it’s essential that rotary indexing tables be incorporated into your manufacturing strategy in order to maximize productivity and profitability.
