A machining fixture, comprising a base, an air cylinder, an air cylinder piston and connecting rod, a supporting guide sleeve, a sliding supporting seat, a thrust ball bearing holder and spherical bead, a floating platform, a first connecting screw, a compression block, a pin shaft, a push rod pin, a second connecting screw, a center positioning shaft, a third connecting screw, a guide sleeve, a supporting plate, an oil cylinder piston and connecting rod and a one-way oil cylinder. The floating centering self-clamping machining fixture is for machining flange-type, which improves positioning accuracy and machining precision. The fixture has an automatic returning floating platform, achieving the automatic alignment of the parts; after the alignment, a floating support moves down and is changed to a rigid support, improving stability; and a positioning rod continues to move down, such that a workpiece is automatically clamped by an ejector rod oscillating arm mechanism.

A method of delivering a collar between a fastener and a swager is provided. The method comprises steps of: (i) advancing the collar from a collar source to a collar feeder, where the collar source is operatively coupled to the collar feeder via a collar-supply tube, (ii) presenting the collar at an outlet of the collar feeder concentrically in line with a central axis of the fastener and with a working axis of the swager, and (iii) retaining the collar at the outlet of the collar feeder using at least one resilient flexure of the collar feeder.

A conveyance jig provided for integrally conveying a separate type control panel with a machine tool that are disposed separately, includes a fixing section with respect to a base and a holding section that holds a separate type control panel in a state of being installed on a movable stand with casters at the rear of the base in order to integrally conveys a machine tool including the base and a processing module that is movably installed to be movable in the front-rear direction along a straight line rail provided on the base separately with a gap in a width direction, and the separate type control panel that is installed on the movable stand with casters and disposed separately from the machine tool.

The invention discloses a mailbox punching device, comprising a baseplate, two frames which are correspondingly arranged at two ends of the top of the baseplate, and a box arranged between the two frames on the two ends through a lifting device. The inner bottom of the box is provided with a first steering cavity with an opening facing downward, and a second steering cavity extends vertically in the box above the first steering cavity. A first sliding groove is connectedly set on one inner wall of the second steering cavity, and a steering platform, through bearings, is rotatably mounted in the first steering cavity. A first steering shaft, which extends into the second steering cavity, is fixedly arranged on the top of the steering platform, and a first bevel gear is fixedly mounted on the first steering shaft in the second steering cavity.

A wheel blank outer rim scribing device is composed of a wheel positioning and clamping system, an upper auxiliary system, a lower auxiliary system, a rim scribing system and a vision detection system. The wheel positioning and clamping system completes positioning of a wheel on a roller bed, clamping and rotating drive; the upper auxiliary system improves the axial positioning precision and power assisting rotation of the wheel; the lower auxiliary system improves the radial positioning precision and power assisting rotation of the wheel; the rim scribing system completes groove ridge machining of the outer rim of the wheel; and the vision detection system detects blanks having insufficient outer rim machining allowance. The device not only can scribe ridges on the outer rim of the wheel, but also can check the blanks having insufficient outer rim machining allowance.

The systems, apparatuses, and methods herein can provide a multi-site positioning mechanism suitable for long-term testing of a device(s) under test (DUT) (e.g. semiconductor wafers) across a range of temperatures with or without a controlled environment. The systems, apparatuses, and methods herein include mounting components, mechanisms, and structures that can provide excellent mechanical stability, permit relatively close working distance optics with high resolution, enable fine positioning at elevated temperature in a controlled environment with minimal thermal perturbation. The systems, apparatuses, and methods herein can be provided with modularity, for example as modular with rails and test sites that can be easily added or removed, and that can permit access to probe modules in a densely packed array.

A rotary table apparatus includes: a rotary table casing; a face plate which is pivotally supported by the rotary table casing and which can freely rotate; and a joint and a free tube into which a power cable is inserted, the power cable supplying power to rotate the face plate, and an adaptor whose mounting direction with respect to the rotary table casing can be changed and which can be attached to and detached from the rotary table casing is placed between the rotary table casing and the joint.

An apparatus for use with a machine tool, including an operating panel via which the machine tool can be controlled by an user and a supporting arm holding the operating panel, which can be mounted on the machine tool by means of a hinge in such a way that the supporting arm holding the operating panel can be pivoted relatively to the machine tool about a vertical axis of the hinge, wherein the apparatus is provided with at least one damping element and/or which dampens an impact of the apparatus which occurs, because of a collision between the apparatus and the machine tool, when the supporting arm is pivoted with respect to the machine tool about a vertical axis.

A contact holder device for a hand-held power tool includes at least one main body that is disposed inside a housing unit of the hand-held power tool. The main body accommodates or fixes contact elements configured to transmit data signals and/or electrical energy. The main body has at least one disposition plane and at least one group of contact elements are disposed in the disposition plane. The main body has at least one further disposition plane and at least one further group of contact elements are disposed in the further disposition plane. The further disposition plane is disposed in an offset manner in relation to the disposition plane.
