Deep hole internal diameter truns into external diameter to and measures specialized tool

The utility model discloses a deep hole internal diameter truns into external diameter to and measures specialized tool, including outer gauge rod and interior gauge rod to and cooperate fine setting screw rod, trimming nut and the fine setting lock nut who uses with outer gauge rod, pressure spring, gauge rod clamp handle, gauge rod lock nut with interior gauge rod cooperation use, the pressure spring be located outer gauge rod, and be located in the middle of fine setting screw rod and gauge rod terminal, the fine setting screw rod is connected with outer gauge rod through interior trimming nut who wears and fine setting lock nut. Practice has proved that this utility model has stopped the various shortcomings of traditional deep hole measuring tool inside micrometer and internal diameter percentage table, truns into " external diameter " to " internal diameter " to and measures. After having had this instrument, need only the external micrometer of a suitable specification or the internal diameter that slide caliper just can measure the deep hole, use " the ovality " and " tapering " that can also detect the deep hole with a clearance gauge cooperation. Practice thrift the measuring tool cost greatly, and convenient operation is easy again. Really, a simple and practical, can solve the novel measurement specialized tool of big problem again.
