Introduction

Wheel hub powers better steering, which has become a must-have for automotive. The industry witnessed a continuous research and innovation since the late 19^th century in automotive. It is one of the most dynamic fields, accounting for at least one in ten jobs in industrialised countries. 

The industry integrates advanced technologies in vehicles to reduce emissions and ensure customers’ safety. However, in a world where material fabrication and metal heat treatment are outsourced, engineers need to be sure materials are properly processed before use.

The Wheel Hub serves as the glue between the wheel and axle. Wheels are attached with studs to the hub assembly. The hub assembly fits on the axle, connecting the wheel assembly to the rest of the car; bridging the wheel and the entire vehicle. 

If one part fails; it creates a ripple effect. A hub is not a single piece of hardware. Instead, it needs a handful of other parts to do its job.

It is mounted with bearings; cylindrical pieces packed with grease that reduces friction during wheel spin. The Wheel Hub bearing is used to increase fuel efficiency, providing smooth and safe ride for passengers with Anti-lock Braking Systems (ABS). 

This research is related to the design of the workholding device for manufacturing the Wheel Hub section that is too long. The design uses the collet mechanism, improvements include adding a pneumatic cylinder for up and down mechanism, for top clamping of the output loader on the top plate that helps hold the component firmly for operations.

The operator ensures proper alignment of the forged component placed and reduces the rate of scrap from misalignment after manufacturing. This workholding provides good working area for the operator in component manufacturing.

Methodology

The idea was to develop a workholding device for manufacturing Wheel Hub part, which can be manufactured to the exact dimensions of the drawing using the GD&T tools.

A standard operating procedure was adopted till the final manufacturing stage. All operations were carried out on CNC and VMC machine, in case of any burs, auto-deburring was carried out at specific speed.

This workholding device is manufactured for a specific machine. The design of this fixture is drafted by keeping all machining considerations, movements and factors. The final working of this workholding was evaluated and specific planning for mass production of four components in a single run was also studied.

The post Machining Wheel Hub For Workholding Device Design appeared first on Asia Pacific Metalworking Equipment News | Manufacturing | Automation | Quality Control.

The maximum groove depth of the system is 4 mm with a groove width of 2 mm or 2.5 mm. For grooving operations, the inserts are available with both straight and full radius cutting edges. Horn offers the indexable insert with a 15-degree chamfer for parting off. A cylindrically ground chip breaker geometry makes for reliable chip removal. The tool carrier is designed as a square shank of 10 x 10 mm or 12 x 12 mm cross section. Each version features an internal coolant supply and is available in both left-hand and right-hand designs.

The post Witte Modular Clamping Chucks appeared first on Asia Pacific Metalworking Equipment News | Manufacturing | Automation | Quality Control.

It is available as a two component system consisting of two master jaws with four, low head socket cap screws and a hex T wrench, and a machinable jaw set consisting of two machinable aluminum jaw plates.

Once reserved for large production runs, automated loading and unloading of machine tools is now becoming more and more commonplace for small batches and individual parts. The goal is to reduce set-up times and enable round-the-clock production with low manpower requirements.

Above all, smooth interaction between clamping pallets, robot couplings, and palletising modules will become increasingly important due to the resulting boost in flexibility.

Starting Points

There are two basic starting points when it comes to the Machine tool automated machine loading. For large series, and also for very long machining times, automated workpiece change has proven to be of great benefit. In this case, workpieces are normally fitted directly onto a power chuck, such as a clamping block or a force-actuated multi-jaw chuck, by a robot or gantry.

For small and medium-sized series, automated clamping device replacement is more suitable. With quick-change pallet systems, clamping devices can be automatically mounted, positioned, and clamped to a reference value within seconds. Standardised palletising systems allow clamping devices to be replaced in a highly flexible way while ensuring a high degree of process stability.

In this case, workpieces and clamping devices are installed on clamping pallets, arranged in storage racks and successively transferred to the machining centre from the pallet storage rack. On the bottom of the pallets, there is a standardised interface to the quick-change pallet system.

Integral Components

Like an adapter, this interface links the machine to a wide range of workpieces. Not only that: Modern pallet systems also feature a side interface so that they can be connected to a robot or gantry in a way that ensures process stability. This makes them an integral component in machine tool automation, as they meet three key requirements: flexibility, precision, and cost-effectiveness.

Today’s most comprehensive and innovative range of modules for automated machine loading includes advanced clamping technology and gripping systems. Products range from quick-change pallet solutions for machine tools to standardised pallets and robot couplings to a wide variety of workpiece clamping devices in all shapes and sizes.

Schunk: Palletising Modules

The Schunk machine tool palletising module Vero-S NSA plus is a quick-change pallet solution for automated pallet changes. It has a flat design and provides a large amount of space in the machine room for workpieces and axis movements. It achieves pull-in forces up to 20,000 N and holding forces over 100,000 N.

These machine tool modules offer a precise hold, even in large-volume cutting operations, and if required, the palletising system can also be integrated directly into the machine table.

A positively driven airflow prevents shavings or dirt from impeding the automated changing process by cleaning the flat surfaces and the short taper. This allows the work surface of the pallet to remain chip-free and flat. Through dynamic pressure monitoring, all process steps can be monitored: module open, module close, and pallet presence.
