摘要:
An inspection apparatus for a laser oscillator includes a dimming plate that dims a laser beam immediately after the laser beam is emitted from the laser oscillator; an imaging unit that images, with a plurality of pixels, the laser beam dimmed by the dimming plate; a processing unit that processes an image captured by the imaging unit; and a display unit that displays the image processed by the processing unit. The processing unit has at least two thresholds of an inner ring and an outer ring used for partitioning the intensity of the laser beam.

A machine tool (2) comprising a mobile table (11) and a support and gripping device (200) fitted to one said machine tool (2) and which comprises:—pincer means (210) for blocking the part;—a support (250) which contains and supports the pincer means (210) and is blocked to the mobile table (11). The pincer means (210) comprise a part blocking pincer (212) and an intermediate pincer (211), respectively one inside the other, both elastic. The part blocking pincer (212) has a structure for gripping the part following interaction between the intermediate pincer (211) and the support. (250); in addition the pincer means (210) are suitable for being placed in rotation around the pincer axis (P-P).

An instantly aligning collet indexer that can be instantly mounted on the standard tooling vises found on most milling machines. A constant clamping pneumatic collet closing system with the valve and manifold is built into the body. The design is compact enough to fit in any standard 6″ machine tool vise and rigid enough to be useful for machining operations. The collet indexer can be used in a vertical or horizontal position in a typical mill vise of a milling machine. The device can be driven by a simple graduated hand crank or by a servo type motor controlled by various programs used in conjunction with a computer.

A work fixing device capable of stably fixing the work, without any biasing, in the longitudinal direction of the work, of the fastening force for fixing the work. The moving mechanism of clamps is constructed by comprising a scroll disc as working disc forming a circular hole in which to insert the work at the center and scroll guides in spiral shape the winding direction of which is opposite to each other from the center toward the outer circumference on the both side faces, a rotary drive mechanism for rotatably driving this scroll disc, and scroll pieces having a fitting portion to be engaged with the scroll guides of the scroll disc and disposed on both sides of the scroll disc in a way to correspond to a plurality of clamps respectively.

An apparatus for use with the chuck of a lathe. The apparatus comprises an angled holder having a first predetermined shape and made of a first predetermined material and a faceplate engageable with the holder, the faceplate has a second predetermined shape and is formed of a second predetermined material. There are, further, bolts for securing the faceplate to the angled holder and another bolt for securing such chuck to the faceplate.

A thread cutting milling tool comprises a shank with a working portion formed with a recess for receiving a thread cutting insert. The thread cutting insert has one edge formed with a line of thread-form teeth of identical profile. The thread cutting teeth project laterally for cutting engagement with a work-piece while the tool spins about its axis. The tool also orbits within or about a work piece, and in one orbit of the tool in a helical cutting path relative to the work piece a number of complete turns of the screw-thread are formed which is equal to the number of teeth of the insert in engagement with the work-piece. A secondary cutter carried on the thread cutting milling tool provides for formation of a pilot portion or counter bore on the work piece at an end of the screw thread. The pilot portion or counter bore provides for alignment of a threaded member which is to engage the screw thread. Also, the secondary cutter provides for formation of a blunt or scalloped full-thread starting end for the screw thread at the pilot portion. The blunt starting end for the screw thread is robust, resists damage, and resists cross threading.

The valve head of the present invention is designed for engaging both a Schrader and a Presta valve. It includes a housing having generally cylindrical sidewalls and a base wall. A collet is disposed within the housing. The collet has generally cylindrical sidewalls and a plurality of upwardly extending collet fingers. A generally cylindrical gasket member is disposed within the collet. The gasket is composed of a resilient material and has a valve insertion bore formed centrally therethrough. A camming lever is operably engaged to the collet and functions to pull the collet downwardly into the housing. The downward movement of the collet causes the collet fingers to move inwardly, thereby creating an inwardly directed force upon the resilient gasket such that the diameter of the gasket bore is reduced. When a Schrader valve is disposed within the gasket bore, a valve pin depression tip acts to depress the Schrader valve pin, thus permitting pumped air to flow through the Schrader valve. When a Presta valve is disposed within the gasket bore, the tip is prevented from applying undue force to the Presta valve pin by a flexible mounting of the tip within the valve head.
