A horizontal support device for horizontally supporting the benchmark measuring device

摘要

The object of the present invention is to provide a horizontal supporting device for horizontally supporting a measuring device used in a benchmark, which is light in weight and stably supports the horizontal of the measuring device.;According to the present invention, there is provided a horizontal support apparatus for horizontally supporting a measurement apparatus of a benchmark, comprising: a benchmark cover (26) for accommodating a ball-shaped benchmark (3); a plurality A plurality of horizontal fixing screws 57 and a plurality of fixing portions 30 which are screwed to the horizontal adjusting screws 57 and fixed to the base, and a measuring device is connected to the upper end of the bench mark lid 26 The bench mark cover 26 accommodates the ball-shaped benchmark 3 and moves by the upward and downward movement of the horizontal adjusting screw 57 in a state of not contacting the base, One end of the horizontal adjusting screw 57 is fixed to the base and the other end is screwed to the horizontal adjusting screw 57. One end of the horizontal adjusting screw 57 is in contact with the bench mark cover 26, The rotation causes the benchmark cover (26) A horizontal support apparatus for supporting the horizontal is provided a measuring device for the benchmark characterized in that the adjustment.
