Title:
GRINDING MACHINE AND MEASUREMENT DEVICE
Document Type and Number:
WIPO Patent Application WO/2011/013710
Kind Code:
A1
Abstract:
A grinding machine, wherein a first grindstone head is provided to a machine base frame (10) with a first movement body (11A) and a first grindstone base (12A) provided therebetween. The base end of a tilting arm (28) is tiltably fitted to the housing of the grindstone head. A measuring instrument (41) is rotatably connected to the tip of the tilting arm (28). A gage (46) and a measuring pin (47) are connected to the lower end of the measuring instrument (41), and the gage (46) is engaged with a crank pin (23a) of a crankshaft. The center (O28) of tilting of the tilting arm (28) is set on the same axis as the center (O15) of rotation of the first grindstone (15A). Even if the tilting arm (28) is tilted to change the position of the measuring instrument (41), the positional relationship between the first grindstone (15A) and the gage (46) does not change, and this enables the position of the gage (46) to be easily adjusted according to the diameter of the crank pin (23a). As a result, the trajectory of movement of the gage of the measuring instrument is simple and the outer diameter of the workpiece can be measured quickly.
