Component Specifications

Definition
The pusher arm/plate is a critical component of servo-driven alignment pushers in industrial automation. It consists of a rigid structural element (arm or plate) attached to a servo motor via a linkage or direct drive. This component executes precise linear or rotational movements to contact and reposition objects on production lines, assembly stations, or packaging systems. Its design ensures controlled force application, minimal deflection, and accurate positioning within tight tolerances, typically ranging from ±0.1mm to ±0.5mm depending on application requirements.
Working Principle
The pusher arm/plate operates on electromechanical actuation principles. A servo motor receives position commands from a programmable logic controller (PLC) or motion controller. Through precision gearing or ball screw mechanisms, rotational motion is converted into linear displacement of the arm/plate. Feedback devices (encoders or resolvers) continuously monitor position, enabling closed-loop control for accurate alignment. The component applies controlled force to workpieces, ensuring proper orientation without damage, and retracts to its home position after each cycle.
Materials
Common materials include: 1. Aluminum alloys (6061-T6, 7075-T6) for lightweight applications with good strength-to-weight ratio. 2. Stainless steel (304, 316) for corrosive environments or high-wear applications. 3. Carbon steel (AISI 1045, 4140) for high-strength requirements. 4. Engineering plastics (POM, UHMW-PE) for non-marring applications. Surface treatments may include anodizing (aluminum), hardening (steel), or coatings (PTFE, nickel plating) to enhance durability and reduce friction.

Frequently Asked Questions

What is the difference between a pusher arm and pusher plate?

A pusher arm typically refers to a rod-like structure used for point contact or pushing from specific locations, while a pusher plate is a broader surface area component used for distributing force across larger workpieces or for pushing multiple items simultaneously.

How do I select the right material for my pusher arm/plate?

Material selection depends on application requirements: aluminum for lightweight needs, stainless steel for corrosive environments, carbon steel for high strength, and engineering plastics for non-marring applications. Consider factors like load capacity, environmental conditions, wear resistance, and compatibility with workpieces.

What maintenance is required for pusher arms/plates?

Regular maintenance includes lubrication of moving joints, inspection for wear or deformation, checking mounting bolts for proper torque, verifying alignment accuracy, and cleaning contact surfaces to prevent contamination buildup.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
