The invention discloses a device for detecting the symmetry of a key groove. The device comprises a detecting frame main body and a plurality of detecting block gauges; a guide rail is arranged on the side surface of the detecting frame main body; a concave detecting position is formed on one side, with the guide rail, of the detecting frame main body; a left positioning device and a right positioning device which are used for fixing the detecting block gauges are arranged on both sides of the concave detecting position respectively; and a dial indicator capable of parallel sliding along the position with the guide rail is arranged on the detecting frame main body. During detection of the device for detecting the symmetry of the key groove, the detecting block gauges are fixed by the left positioning device and the right positioning device, and embedded into corresponding key grooves to be detected; the dial indicator of which the moving trace is parallel to the guide rail is provided; due to the sliding of the dial indicator along the guide rail, displayed values of the dial indicator at the most highest points of shaft outer diameters to be detected are measured respectively; and a symmetry deflection value is obtained according to the two displayed values. The detection device and the detection method of the device are convenient in regulation; moreover, the measurement method is simple; the detection cost is saved and convenience is brought to detectors; and the invention is used in the field of symmetry detection.

A polymer extrusion head for forming continuous shapes having one or more lumens therein. The head includes an extrusion mandrel and die. At least one lumen pipe is disposed radially through a port in the die to intersect the polymer flow in the annular region between the tip and the die. The lumen pipe is a welded assembly having a 90° turn formed as a mitered joint with zero bend radius. The lumen pipe is held in a pin vise engaged in the die such that position of the lumen pipe may be readily adjusted. Axial and radial positions are established during assembly by means of a gauge block. A plurality of lumen pipes may be accommodated for a plurality of lumens by a manifold distribution system including individual lumen pipe assemblies.

A wear gauge is provided for simulating the wear of a magnetic recording component at its interface with a magnetic storage medium comprising a wear gauge block having a wear surface that substantially approximates the geometrical dimensions and contour of the working surface of the magnetic recording component, wherein the wear surface has a coating of transparent material. A test method comprises mounting the wear gauge in a test fixture, positioning a tape and adjusting the overwrap angle at edges of the wear surface, choosing the desired tape tension, speed and runtime, and running the tape, preferably unidirectionally, in operational contact with the wear surface for the desired runtime. The wear surface is inspected under white light illumination to observe and record locations of interferometric color changes on the wear surface. The color changes are correlated to thickness changes of the transparent coating on the wear surface.

Lateral pins (20) are used to provide a tufting machine modular gauge assembly that allows damaged or broken gauge elements (10) to be replaced individually. The modular gauge assembly consists of a gauge bar (25) with a plurality of modular blocks (15) removably attached to the bar. The modular blocks are six sided with a detent (110) and fastener mechanism (65) for attaching the block to the gauge bar. The gauge elements may be attached to the block by dedicated screw-pins (145) or by a lateral pin (20) that passes through all the gauge elements within a block. The lateral pin may either pierce the gauge elements (at 70) or abut the gauge elements. Abutting pins may be malleable and segmented and secured in position by set screws.

The invention discloses a device and method for calibrating a stay wire displacement sensor. The calibration device includes a bottom plate and gauge blocks. A sensor setting position used for placing the stay wire displacement sensor is arranged on the bottom plate, and the gauge blocks are arranged on the bottom plate and are located at one side of the sensor setting position. The device for calibrating the stay wire displacement sensor is simple in structure and convenient to install, and can be used repeatedly, thereby improving calibration efficiency.
