A valve clearance measuring assembly includes a panel having a first side, a second side, a forward edge and a rearward edge. The forward edge is extendable between a valve tip and a rocker arm. The first and second sides of the panel each are planar and orientated planar with respect to each other. A head includes a central member and a pair of arms. The arms extend in a generally same direction with respect to each other to define a space between the arms. The panel is attached to the arms and traverses the space. The forward edge is in static communication with the arms such that the forward edge is in a linear configuration as the forward edge traverses the space.

A robot includes an actuator that changes an angle of a second member relative to a first member in accordance with a command value. In a first step of an angle calibration method, a measurement object distance is obtained by measuring a distance between wall surfaces of the two measurement object portions, the measurement being made while the actuator is given an arbitrary command value. In a second step, an angular difference is obtained by calculation, the angular difference corresponding to a difference in distance between two measurement object portions, the calculation being made based on a reference measurement object distance obtained in the past and the measurement object distance obtained in the first step, the reference measurement object distance having been obtained by measuring the measurement object distance while the actuator was given an arbitrary command value.

A method and apparatus for identifying locations for holes for a stackup of parts. In one illustrative example, a required edge distance for a hole for the stackup of the parts is identified. A measurement tool is selected based on the required edge distance identified for the hole. The measurement tool comprises a circular section having an edge and an indicator centrally located with respect to the edge of the circular section. The edge of the circular section of the measurement tool is associated with a part in the stackup of the parts. A location on the part for a center of the hole for the stackup of the parts is identified using the indicator.

Methods to use a tool for dimensional verification of a vehicle frame suspension system bracket pocket having first and second cam slots, the tool including a first sub-assembly configured for insertion through and registration of the first cam slot; a second sub-assembly configured for insertion through and registration of the second cam slot; and an intermediate sub-assembly disposed between and attachable to the first and second sub-assemblies via a shaft, the intermediate sub-assembly including an extension rod receiving feature defining at least one extension rod receiving aperture; wherein the sub-assemblies lock against the bracket walls to define a horizontal center axis and are adjustable to determine and register a center point along an intersecting vertical center axis between the first and second cam slots that is alignable with the at least one extension rod receiving aperture.

A measurement device according to one embodiment of the present disclosure is a measurement device that measures a position of an annual part to be measured that is arranged at an opening edge of a hole formed in a member to be measured, and the measurement device includes: a probe that is displaceable in an axial direction; a holder that holds the probe; and a measurement instrument that measures displacement of the probe in the axial direction. The probe includes an inclined portion at an tip end of the probe, the inclined portion being inclined relative to a central axis of the probe at an angle equal to an angle defined between a central axis of the hole in the member to be measured and a horizontal plane in a state in which the member to be measured is mounted on the horizontal plane.

A bollard drilling jig including a base plate, an elongated bar coupled to the base plate, and at least two guide collars spaced apart from each other on the elongated bar. The at least two guide collars each include an interior channel that is sized to receive a drilling tool therethrough.

An end play measurement apparatus is provided that measures end play of a tapered roller bearing of a gear unit. The gear unit supports a large-gear shaft, with which a gear is fitted, via the tapered roller bearing. The end play measurement apparatus includes a power generation unit, which is fixed to the large-gear shaft and generates power to move the gear unit backward and forward in the axial direction, a position change unit, which is interposed between the power generation unit and the gear unit and changes the axial position of the gear unit by using the power of the power generation unit, and a booster mechanism, which has a free end that receives the power of the power generation unit to boost the power.

The present invention provides a measuring tool comprising a support portion and a measuring portion, the measuring portion is movably connected to the support portion, the support portion is configured for supporting the measuring portion, the measuring portion is configured for successively measuring at least one gap between a base and a workpiece on the base. The measuring tools, by providing a measuring portion capable of successively measuring at least one gap between the rubbing base and the rubbing roller, avoid frequent replacement of the measuring portion, thereby the measuring efficiency is increased greatly, and the utilization rate of processing equipment is improved.
