Products Description
Hansheng cam indexers provide intermittent rotary motion for positioning workpieces in automated welding equipment. Typical applications include rotary welding tables, multi-station welding fixtures, and robotic welding cells. The required indexing angle, station count, mounting arrangement, and drive configuration depend on the machine layout. To select a suitable model, provide the workpiece and fixture weight, fixture dimensions, required cycle time, and indexing angle.
Technical specifications and available configurations for Welding
The table-type cam indexer is designed for applications that require controlled rotary indexing with a defined dwell period between movements. Model selection depends on the load, fixture design, production cycle, and available installation space.
| Technical parameter | Specification |
|---|---|
| Product type | Table-type cam indexer |
| Indexing accuracy | Standard rating: ±30 arcseconds. Higher accuracy configurations are subject to model availability and technical confirmation. |
| Number of stations | Common configurations include 2, 3, 4, 6, 8, 10, and 12 stations. Other arrangements require technical review. |
| Load capacity | Model dependent. Selection must account for workpiece and fixture weight, load distribution, center of gravity, and allowable torque. |
| Output configuration | Table or disc output, with dimensions and mounting interfaces determined by the selected model. |
| Drive configuration | Motor and drive options are selected according to the indexer's input specifications and operating cycle. |
| Hollow center | Availability depends on the selected model and design requirements. |
| Environmental protection | Sealing, lubrication, and surface protection are specified according to the operating environment. |
These specifications provide a starting point for product selection. Final ratings and available configurations must be confirmed against the selected model and actual operating conditions before ordering.
Applications in automated welding
Rotary welding tables
A cam indexer rotates a welding fixture to preset angular positions, bringing different areas of the workpiece into position for welding. During the dwell period, the output remains at the designated station position according to the indexer's motion profile, allowing the welding operation to proceed.
Multi-station welding fixtures
In a multi-station welding system, the indexer moves the fixture between designated working positions. Depending on the machine layout, these stations can accommodate different stages of production, such as loading, welding, inspection, and unloading.
Robotic welding cells
A cam indexer can position workpieces or fixtures within a robotic welding cell. Its indexing angle, dwell time, motion profile, and load capacity must match the robot's working range and the required production cycle. The control sequence must also account for the selected motor, drive, and machine controller.
Manufacturing and quality control
The manufacturing process of a cam indexer involves several stages, from housing preparation and cam machining to assembly and final inspection. Each stage affects the dimensional accuracy, transmission performance, and operating stability of the finished unit.
Cast iron housing and base machining
The housing and base are made of cast iron to provide a rigid structure for the transmission components. After casting, the housing undergoes stress relief to reduce residual stress before precision machining. Mounting surfaces, bearing seats, and assembly interfaces are then machined to the required dimensions to support accurate alignment.
01
Cam profile machining and heat treatment
The cam profile is machined according to the designed motion curve. The cam undergoes carburizing and quenching, followed by tempering and precision grinding. These processes improve surface hardness and wear resistance while maintaining the profile accuracy required for the specified indexing motion.
02
Roller and transmission component processing
Rollers and other critical transmission components receive appropriate heat treatment and precision finishing according to their materials and design requirements. Dimensional and surface inspections help ensure proper fit and consistent engagement within the indexing mechanism.
03
Assembly and running-in
During assembly, the cam and roller mechanism is fitted and adjusted to meet the specified engagement requirements. The assembled unit then undergoes running-in and functional checks to assess input rotation, output indexing motion, dwell behavior, and mechanical operation.
04
Final inspection and performance testing
Before shipment, each cam indexer is inspected against the applicable product specifications. Checks cover mounting dimensions, mechanical operation, indexing performance, and unusual noise or vibration. Positioning accuracy and other performance requirements are verified according to the selected model and its specified ratings.

How to select a cam indexer for welding automation
Selecting a cam indexer requires a review of the workpiece, fixture, motion requirements, and machine layout. The following information helps determine a suitable model and configuration.
Workpiece and fixture weight: Provide the combined weight of the workpiece, fixture, and components mounted on the output table. Include the center of gravity and any eccentric loading.
Table dimensions and installation space: Specify the required table diameter or dimensions, mounting arrangement, available space, and installation orientation.
Number of stations and indexing angle: State the number of working positions and the angular movement between stations. Include any requirements for a non-uniform indexing sequence.
Production cycle: Provide the target cycle time, dwell time at each station, operating frequency, and expected duty cycle.
Motor and control requirements: Identify the preferred motor type, drive specifications, PLC or controller, and any coordination requirements for the welding robot.
Operating environment: Describe the expected temperature, welding spatter, dust, moisture, cable routing, and any additional protection requirements.
Drawings and application details: Supply the machine layout, fixture drawings, mounting interfaces, reference photos, or details of the existing equipment.
Hansheng can review these details to determine the appropriate cam indexer configuration for the application. Complete technical information helps establish the required load rating, indexing performance, mounting interfaces, and drive arrangement before the final model is selected.

FAQ
Q: Can a cam indexer be integrated into a robotic welding cell?
A: Yes. A cam indexer can be used in robotic welding cells to position workpieces at successive welding stations. Integration depends on the selected indexer, drive configuration, control system, and required cycle sequence. The indexing motion and dwell time should be coordinated with the robot's operation and the overall machine cycle.
Q: How do I select the right cam indexer for welding automation?
A: Selection depends on several factors, including workpiece and fixture weight, table dimensions, load distribution, required indexing angle, number of stations, and production cycle time. Installation space, mounting orientation, and drive requirements should also be considered. Providing these details helps determine a suitable configuration for your application.
Q: Can the indexing angle and number of stations be customized?
A: Customization may be available for indexing angles, station numbers, mounting arrangements, and drive configurations, depending on the product design and application requirements. Share your machine layout and indexing specifications with our team to confirm the available options.
Q: What information is needed to request a cam indexer quotation?
A: To evaluate a cam indexer for your welding equipment, provide the workpiece and fixture weight, table dimensions, required indexing angle, number of stations, target cycle time, and installation conditions. Drawings, layout diagrams, or details of the existing drive system are also helpful for technical evaluation and quotation.
Q: What maintenance is required for a cam indexer used in welding automation?
A: Maintenance requirements depend on the indexer model, operating conditions, duty cycle, and installation environment. Follow the manufacturer's instructions for lubrication and inspection. Regular checks should include mounting fasteners, unusual noise or vibration, lubricant condition, and indexing performance. In welding environments, also assess whether the installation requires additional protection from welding spatter, dust, or heat.
