摘要:
When a slide member mounted with a tool reciprocates on a guide member reach one end and the other end positions of the guide member, permanent magnets provided on the guide member and the permanent magnets provided on the slide member repel each other to give the guide member forces for reversing its moving direction. The guide member is provided to be movable with respect to a base and repulsive forces between permanent magnets provided on the base and permanent magnets provided on the guide member are used to retain an axial position of the guide member.

A machine for measuring the dimensions of a workpiece, comprising a base te for receiving the workpiece and a mechanical structure carrying a feeler for movement along three orthogonal axes at right angles by means providing for direct measuring of the amounts of movement of the feeler along the axes. Optical deviation measurement means determine the errors due to deformation of the components, lost motion as well as pitch, yaw and/or roll of the movable components. The corrections to be applied to the data delivered by the measuring means are computed and may be made automatically for the display to be free of errors.

A quick elevating and micro-adjusting device for the worktable of a manual planer includes a base, a stationary worktable, a movable worktable and an adjustment device. The adjustment device has its support shaft inserted in the fixing holes of two side plates of the movable worktable. The adjustment device has an elevating rod to be moved up or down for actuating the support shaft to quickly move the movable worktable upward or downward. A micro-adjusting rod has its worm engaged with the worm gear of a threaded shaft for rotating together to drive the threaded rod of the threaded shaft to rotate and move the holding frame of the threaded shaft, which is secured on the movable worktable. Thus, by turning the micro-adjusting rod, the movable worktable can be micro-adjusted in position. Thus the worktable can be adjusted quickly and precisely.
