Described pedestal is provided with the draw-in groove for clamping slide calliper rule measuring jaw.
Described draw-in groove is U-shaped.
The bottom land of described draw-in groove is provided with escape.
Described draw-in groove is provided with fixed connection structure, and described fixed connection structure includes the spiral shell being arranged on the cell wall of groove Pit.
Described screwed hole has four, one group two-by-two, and two screwed hole coaxial lines of same group set up separately at the two of described draw-in groove On side channel wall.
Described connecting portion front end face has and stretches into portion for extend in groove to be measured, described in stretch into portion and be connected with described Portion front end face forms step surface, described step surface place plane with stretch into portion to stretch into direction vertical.
Described probe is arranged on the tail end in the portion of stretching into, and it is towards vertical with the described bearing of trend stretching into portion.
Described measurement end is circular arc.
Survey tool, the measurement frock on the outer measuring jaw or inner measuring jaw of slide calliper rule including slide calliper rule and clamping, groove internal diameter is surveyed Amount frock includes pedestal, extend into and treat when described pedestal having for releasable connection connecting portion on slide calliper rule measuring jaw and use Surveying the probe in groove, probe has the measurement end for contacting with the corresponding cell wall of groove to be measured.
Described pedestal is provided with the draw-in groove for clamping slide calliper rule measuring jaw.
Described draw-in groove is U-shaped.
The bottom land of described draw-in groove is provided with escape.
Described draw-in groove is provided with fixed connection structure, and described fixed connection structure includes the spiral shell being arranged on the cell wall of groove Pit.
Described screwed hole has four, one group two-by-two, and two screwed hole coaxial lines of same group set up separately at the two of described draw-in groove On side channel wall.
Described connecting portion front end face has and stretches into portion for extend in groove to be measured, described in stretch into portion and be connected with described Portion front end face forms step surface, described step surface place plane with stretch into portion to stretch into direction vertical.
Described probe is arranged on the tail end in the portion of stretching into, and it is towards vertical with the described bearing of trend stretching into portion.
Described measurement end is circular arc.
The invention has the beneficial effects as follows: compare and prior art, the present invention uses additional survey on traditional slide gauge The mode of amount frock, can change different measurement frocks in time for different grooves, have higher versatility and interchangeability, Reduce production cost;
Further, the present invention uses to arrange on the pedestal measuring frock and stretches into portion and probe, for the difference of different inner diameters The groove of the degree of depth all can realize effective measurement, has high practicality.
