Products Description
The Table Type Cam Indexer by Hansheng is specifically engineered as the core positioning unit for rotary welding tables and multi-station welding automation. Featuring a wide disc output and high load-bearing capacity, it securely holds heavy welding fixtures and workpieces.
Designed to seamlessly integrate with robotic welding cells (such as ABB, FANUC, and Yaskawa), it ensures ultra-stable, zero-backlash station indexing (±30 arc-sec), completely eliminating weld seam misalignment caused by vibration.

Why It Excels in Welding Environments
High Dynamic Stability
The pre-loaded cam follower mechanism withstands the heavy impact and inertia of rapid starting and stopping, ensuring the workpiece remains dead-still during arc or spot welding.
Large Hollow Center (Optional)
Designed with a hollow through-hole to easily route welding cables, shielding gas hoses, and pneumatic lines without tangling during rotation.
Harsh Environment Protection
Sealed with high-quality oil seals and special high-temperature synthetic grease, preventing welding spatter, dust, and extreme heat from affecting internal gears.
How does it work in welding automation?
Cam profile design: The cam (through precision CAD design and CNC machining) has a unique profile curve that is tailored to the welding step requirements.
Intermittent motion conversion: When the motor drives the cam to rotate, the cam profile interacts with the driven roller to convert the output shaft movement into precise intermittent rotation.
Workpiece alignment: Each rotation positions the workpiece at a preset angle (such as 90°, 180°) or linear position, ensuring that the weld seam is precisely aligned with the welding gun/robot.

FAQ
Q: Can it be integrated with welding robots (such as FANUC, ABB)?
A: Yes. Our indexers are equipped with ISO 9409-1 standard mounting flanges and can be directly connected to mainstream brand robots. We provide motion control software to ensure that the indexer rotation is synchronized with the robot welding path.
Q: What is the service life under intensive use?
A: With proper maintenance (lubrication every 500 hours), the service life is more than 15,000 hours - equivalent to more than 3 years of operation of a two-shift production line.
Q: Can the cam indexer be used in high temperature or humid environments?
A: It can adapt to extreme environments:
High temperature scenarios: When the ambient temperature is greater than 40°C, it is recommended to replace it with synthetic high temperature grease (such as Shell Gadus S2 V 220) and add a cooling fan;
Humid environment: Standard zinc-nickel alloy coating (salt spray test > 1000 hours), optional sealed respirator or desiccant box to prevent internal condensation.
Q: How to rapidly find and fix the problem?
A: Problems and solutions that happen a lot:
More divergence from the correct position: Check for cam wear (use red lead powder to find contact areas that are more than 85% worn) or bearing clearance (if radial clearance is more than 0.1 mm, the bearing needs to be replaced).
Vibration that isn't normal: Check the tension of the transmission belt (deflection ≤ 5mm/1000mm) and make sure the installation base is still flat.
Sudden spike in temperature: Stop the machine right away and check the grease level. If it gets carbonized, clean it well and throw it away.
Q: Can the indexer be synchronized with my welding robot?
A: Yes. By attaching a standard servo motor to the input shaft, the indexer can be controlled via your PLC to perfectly synchronize the rotary table's motion with the robot's welding path.
Q: How does it perform in high-temperature welding cells?
A: For ambient temperatures exceeding 40°C, we utilize synthetic high-temperature grease (e.g., Shell Gadus S2 V 220) and equip the housing with optional heat shields to ensure consistent performance over 15,000+ hours.
Q: What happens if there is an emergency stop during welding?
A: Our cam indexers are built with a high safety factor. In the event of an E-stop, the self-locking nature of the cam mechanism prevents reverse rotation, protecting both the workpiece and the robotic arm.
