A bumper apparatus for securing a vehicle bumper during painting and repair is described herein. The apparatus includes a base support structure, a frame coupled to the base support structure, at least one rear coupler arm movably coupled to the frame, at least one front coupler arm movably coupled to the frame via a front coupler attachment, and a front coupler. The front coupler attachment includes a frame portion movably coupled to the frame, a ball portion fixedly coupled to the frame portion, a socket portion configured to receive the ball portion, and an arm portion movably coupled to the at least one front coupler arm. The front coupler is movably coupled to the at least one front coupler arm and is configured to be releasably coupled to the vehicle bumper.

Magnetic coupling devices are disclosed having magnetic field sensors. The magnetic coupling device may include degaussing coils wrapped about pole extension shoes of the magnetic coupling device.

A holding apparatus, in particular a chuck, for a substrate comprises a main body with a upper side, a carrier element arranged in a recess of the main body so as to be vertically movable such that it can be adjusted between a protruding loading position and a retracted clamping position, the carrier element comprising a support surface for placement of the substrate. The support surface has a smaller diameter than the main body. A lifting element lifts the carrier element to the loading position. The carrier element seals the recess such that a sealed cavity is provided between the main body and the carrier element, which cavity can have a negative pressure applied thereto which counteracts the effect of the lifting element.

A support device (10) includes a substrate receiving region. The support device (10) includes a support body (110) shaped as a pattern having an array of openings (130). The support body (110) is a sparse structure wherein a joint area of the openings of the array of openings (130) is 40% or more of the area of the substrate receiving region. The support body (110) includes one or more suction openings (140) configured to be in fluid communication with a vacuum source arrangement.

This air control device for mounter is to solve a problem of realizing an air control device for a mounter capable of providing a secured holding state by a nozzle without damaging a part by adjusting, during vacuum suction, an amount of air to be drawn suitably for the part and the nozzle. This air control device for mounter is configured such that a nozzle n detachably attached to a head module HM of a mounter is connected to a negative pressure region, and a part is suctioned at a distal end of the nozzle n. The head module HM is mounted with a variable throttle mechanism 4, and by using the variable throttle mechanism 4, an amount of air to be drawn into the negative pressure region from the nozzle is adjustable.

A system for supporting workpieces during machining. The system comprises one or more adjustable workpiece support assemblies and a robotic unit. Each workpiece support assembly comprises a pedestal and a rotatable fixture element. The robotic assembly comprises means of mobilizing and immobilizing each support assembly, so that the fixture element may be secured in a particular orientation. The robotic unit moves along a frame, and manipulates and fixes the position of the fixture elements to match the contour of a workpiece. Vacuum forces may be applied through the workpiece support assemblies to secure the workpiece against the fixture elements.

An apparatus for securing a wafer includes a chuck, at least one O-ring disposed on the chuck, a vacuum system connected to the chuck, such that the vacuum system comprises a plurality of vacuum holes through the chuck connected to one or more vacuum pumps, and a controller configured to control the height of the at least one O-ring relative to the top surface of the chuck. The controller is connected to pressure sensors capable of detecting a vacuum. The at least one O-ring may include a plurality of O-rings.

A method and apparatus. The apparatus comprises a first portion of a tool and a second portion of the tool. The first portion of the tool has a first surface. The first surface has a shape that is complementary to a first portion of a part. The second portion has at least one of a second surface configured to be recessed from a second portion of the part or a hollow portion.

A portable press is usable with parts that are assembled by interference fit or friction fit. A force application member slidably engages a plurality of guides. An actuator, such as a pneumatic or hydraulic jack or cylinder, applies force to the force application member to move the force application member toward a static plate. The force application member acts to either press in, or press out, a first part relative to a second part. The press of the invention is portable, so that the press can be moved to the mechanical structure requiring a press for removal or insertion of parts. The press may be constructed in a vertical or horizontal embodiment.
