what is Intermittor rotary indexer
The Intermittor rotary indexer is a core device that realizes the "intermittent motion" of the output shaft through the interaction of cams, rollers and indexing gears - that is, it completes the "rotation-stop" action at intervals according to preset angles (such as 15°, 30°, 45°, etc.), accurately controls the stay and switching of the workpiece at different workstations, and is suitable for automated processing, assembly, and inspection scenarios that require high-precision positioning.
Structural and process features:
Using high-strength cast iron/alloy steel integral casting with ribbed design in important places and a great ability to resist deformation;
The cam and roller are ground using high-precision CNC machines that leave a surface roughness of ≤Ra 0.4μm and a corresponding clearance of <0.01mm. This makes sure that the movement doesn't get stuck or have a gap.
The whole is heat treated and surface hardened, and the wear resistance is increased by 50%, and the service life can easily reach more than 8 years.
Product Features
1. High accuracy
The indexing accuracy is ±30 Arc Sec. The one-piece design and high-quality alloy steel, Precision heat treatment and surface hardening treatment improve the resistance to deformation. High-precision machining brings cam and roller accuracy to the micron level, eliminating backlash and ensuring accurate indexing every time.
2. High Rigidity
The Intermittor rotary indexer is constructed of high-strength cast iron or alloy steel cast in one piece, which reduces the number of joints and improves overall rigidity. The cams, rollers and spindles are made of high quality, high strength alloy steel which is hardened, carburized and case hardened. It improves the wear resistance and deformation resistance, and also adopts the design of reinforcing rib in the key parts to ensure the high rigidity when running at high speed.
3. Good craftsmanship
The cam curves and rollers are finely crafted by high-precision CNC grinding machines, coordinate boring machines and other equipment to ensure that the contour accuracy is micron level. The key parts are hardened by heat treatment process. Cams and rollers are finely ground to ensure surface roughness below Ra 0.4μm, reducing friction and wear. The cams and rollers are rigorously assembled using specialized working and inspection tools to ensure that the cam and roller fit gap is less than 0.01mm. Finally, laser inspection equipment is used to perform real-time calibration of indexing accuracy and repeatability to ensure that the error is within tolerance.
4. Customizable
Provide customized service, the number of work stations 2, 3, 4, 6, 8, etc., a variety of work stations for your choice, can be flexibly adjusted. We can customize the diameter, height and journal to meet the installation space. Diversified drive mode, you can choose direct motor connection, synchronous wheel or gear drive. Flanges support customization. In order to meet the needs of customers in special environments, such as high temperature resistance, dustproof and other needs.

application
automated line of manufacturing
Particularly in multi-station processing and assembly operations, the intermittor rotary indexer is absolutely essential in automated production lines. It can exactly rotate the workpiece depending on the specified angle by carefully controlling the indexing angle and dwell duration, so completing several operations like milling, drilling, and assembly. Large-scale manufacturing lines including household appliance assembly and automotive manufacture depend on this tool extensively since it can increase production efficiency and processing accuracy.
equipment for packaging
Often employed in equipment like packaging machines, labelling machines, and sealing machines to guarantee proper positioning and timed processing of items, intermittent rotary indexers find employment in the packaging sector. In a packaging production line, for instance, bottles or boxes must regularly engage several procedures and the indexer can precisely send the objects to the next station to prevent misalignment and delays. Its great stability and precision enable packaging accuracy and speed to be raised.
Electronic manufacturing
Particularly in the process of dispensing, patch and assembly of electronic components, the electronic manufacturing sector has high expectations for great-precision assembly. Throughout processing, the intermittent rotary indexer guarantees that every workpiece is positioned at the proper angle and position. In SMT placement machines, for instance, provide precise component delivery to the installation point, hence enhancing production efficiency and assembly quality.
Manufacturing machinery
In printing machines, colour changeover, paper delivery, and print position modification call for quite precise positioning control. To guarantee printing quality, may transfer paper or printing plates to the proper place depending on a specified angle, achieve intermittent rotation and stop, and assist printing equipment maintain high precision and stability at high speeds.
Food and drug sectors
Motion index drives are frequently found in food and pharmaceutical industry manufacturing lines in operations like labelling, filling, and dispensing. In a filling machine, for instance, the indexer can precisely supply cans or bottles to the filling position and halt at exactly timed intervals to assist the filling process. Furthermore depending on this high-precision equipment is the drug packaging and dispensing in the pharmaceutical sector, which guarantees proper operation of every drug packaging station.
Production Machining
In machining,it is extensively applied in lathes, milling machines and other equipment to help precisely finish cutting, milling and other procedures. On milling machines, for instance, indexers may precisely manage the angle and depth of every cut, increase processing precision, and guarantee great efficiency and good quality during the processing.
Textile Sector
Looms and warping machines in the textile sector can precisely index and manage fabric feed. By guaranteeing that every yarn movement is continuous and exact, the indexer can guarantee constant quality of every batch of fabrics, therefore lowering mistakes and increasing production efficiency.
Scientific and experimental equipment
Applied in laboratories and scientific research equipment in cases requiring exact control of indexing angles and periodic motions. In automated tests, for instance, indexers can precisely rotate samples or instrument components to designated positions as needed, therefore offering consistent experimental support.
Extensively applied in current manufacturing and automated production processes and offer effective and accurate indexing control for many sectors through these applications.
FAQ
Q: How to select the model according to the equipment requirements?
A: Three important points:
① Load (select a model with radial load ≥ 1.2 times the weight of the equipment workpiece);
② Number of stations (e.g. 60° interval for 6 stations);
③ Accuracy requirements (±30 seconds for electronics/medical, ±60 seconds for ordinary packaging).
Q: What should be paid attention to during installation?
A: It is necessary to ensure that the concentricity deviation between the input shaft and the motor shaft is less than 0.1mm, and the fixing bolt torque is tightened according to the specification (M10 bolts are recommended to be 25N・m). After installation, test run for 30 minutes to check for abnormal noise or vibration.
Q: Compared with ordinary indexers, what are the advantages?
A: Ordinary indexers have an accuracy of ±1 minute, large gaps, and are easy to wear; while the Intermittor indexer is cast and precisely processed, with an accuracy increase of 1 times, and a gap reduction of <0.01mm. It is still stable under heavy loads and is suitable for high-precision and high-frequency operation scenarios.
Q: How long is the maintenance cycle?
A: Replace the special grease (NLGI Grade 2 lithium-based grease is recommended) after the first 300 hours of operation, and replace it every 2000 hours thereafter; regularly clean the dust on the cam surface and check whether the roller has cracks (recommended once every six months).
