The upper pressure type projects detection instrument, it is characterized in that：The magnetic support top surface is cascaded surface, respectively per single order top surface
It is provided with magnet or electromagnet.
The upper pressure type projects detection instrument, it is characterized in that：The magnetic of magnet or electromagnet set by per single order top surface
Field intensity enhances with height.
The upper pressure type projects detection instrument, it is characterized in that：It is described top including adjustable centre, spring, casing, lid
Plate, adjusting screw, described sleeve pipe is interior to be arranged adjustable centre, is arranged between the adjustable centre upper end and described sleeve pipe lower end
The cover board of spring, cannula tip opens threaded hole, and the threaded hole matches adjusting screw.
The upper pressure type projects detection instrument, it is characterized in that：The top lower face is spherical surface.
The upper pressure type projects detection instrument, it is characterized in that：The adjustable centre lower face is spherical surface.
The utility model adsorbs connecting rod workpiece pressing by magnetic support, applies pressure from workpiece top, it can be ensured that workpiece is straight
It is vertical, it is minimum compared to the power needed for the middle section or bottom, and also magnetic support can make staged to adapt to height not as needed
With part, can also on each step surface embedded magnet or with electromagnet by switch control magnetic support magnetic force whether there is or not can
With in the stronger magnet of relatively high magnetic support face setting magnetic field intensity or electromagnet, magnet usage time is long, and from top
Compressing component does not stop light conduction.In addition, shock mount and being set adjustable centre end face between adjustable centre and casing
Spherical surface can be to avoid the damage to part upper surface, and excellent to eccentric shaft parts is applicable.
