Automated Measurement Cell

Hexagon Manufacturing Intelligence (North Kingstown, RI) announced the 360 Flexible Measurement Cell, an automated measurement work cell suited for automotive and aerospace structure applications including powertrain and closure panel fabrication. The cell is built on commercial-off-the-shelf (COTS) work cell systems integrated with the company’s measurement solutions. The cell combines external devices, products, processes, and systems in a COTS format to enable them to be easily customized. The cell is scalable, portable, and modular, and is offered in three configurations: in-line, near-line, or off-line. Solutions are scalable as required by specific part size and measurement tasks.

Accelerometers

The Model 356A43, 356A44, and 356A45A miniature triaxial ICP® accelerometers were introduced by PCB Piezotronics (Depew, NY). They measure 0.4 × 0.4 × 0.75", weigh 4.2 grams, and are TEDS IEEE 1451.4 enabled. The TEDS feature self-identifies the accelerometer and describes type, operation, and attributes. Data contained in the TEDS programming includes manufacturer, model number, serial number, calibration date, sensitivity, frequency response, and measurement ID. Models are available with three sensitivities: 10 mV/g, 50 mV/g, or 100 mV/g. They are packaged in a hermetically sealed titanium cube. Common applications include modal and structural analysis, automotive NVH, and package testing.

Weldable Couplings and Collars

A line of weldable shaft collars, couplings, and mounts is available from Stafford Manufacturing Corp. (North Reading, MA). The components are made from ANSI 1018 steel and stainless steel to allow users to modify parts and create assemblies without fasteners. Typical modifications include brackets, cams, lever arms, mounts, pins, and rods. They are suited for the design and repair of special machinery, conveyors, packaging systems, and racks. The weldable shaft collars are available in one- and two-pieced, and hinged styles. Flange mounts are offered in ¼" to 6" bore sizes, and weldable shaft couplings are available in ¼" to 2" bore sizes. Smooth-, hex-, and square-bores for shafts, pipe, and tube can be supplied.

Linear Guide Kit

To simplify product selection of self-lubricating linear guides, igus (East Providence, RI) has developed a modular construction kit for belt-driven DryLin ZLW linear axes. The ZLW toolkit enables users to customize their solutions, including rail widths, system length, etc., even for small installation spaces. Cross beams, rails, and/or carriages are available in either aluminum or stainless steel to suit a wider range of application requirements. The ZLW system enables loads up to 165 lbf. to be lifted with stroke lengths of up to 3 meters (118"). Wide drive belts can also permit speeds of more than 5 m/s (16 ft./s), depending on the load. Underwater applications are possible via a special toothed belt.
