Abstract
The utility model discloses a kind of umbrella shape Calibration frock, include vertical main shaft, main shaft is vertically provided with multiple proximity Hall switch, Yuan Zuo edge, main shaft bottom is hinged with multiple exhibition arm by jointed shaft, and each jointed shaft is separately installed with rotary angle transmitter, main shaft is slidably fitted with slip ring, and connecting link rod end hinged on slip ring respectively one_to_one corresponding is hinged on exhibition arm, and slip ring inwall is also provided with magnetic.The utility model can realize the measurement of bore quickly and easily, and has higher measuring accuracy.
Description
Technical field
The utility model relates to pipe diameter measuring device field, is specially a kind of umbrella shape Calibration frock.
Background technology
caliber is one of important parameter of pipeline, after therefore pipeline processing completes, needs to measure caliber.In prior art, the measurement of pipe external diameter more for convenience, but has certain length due to pipeline, the measurement then comparatively inconvenience of bore.
Utility model content
The purpose of this utility model is to provide a kind of umbrella shape Calibration frock, to solve the problem that prior art bore measures inconvenience.
In order to achieve the above object, the technical scheme that the utility model adopts is:
A kind of umbrella shape Calibration frock, it is characterized in that: include vertical main shaft, main shaft is vertically provided with multiple proximity Hall switch, main shaft bottom is connected with round seat, circle seat edge is hinged with multiple exhibition arm by jointed shaft, multiple exhibition arm is circumferentially uniformly distributed, and each jointed shaft is separately installed with rotary angle transmitter, described main shaft is slidably fitted with slip ring, slip ring is hinged with multiple circumferentially equally distributed connecting link, multiple connecting link rod end respectively one_to_one corresponding is hinged on exhibition arm, described slip ring inwall is also provided with the magnetic coordinated with each proximity Hall switch work.
Described a kind of umbrella shape Calibration frock, is characterized in that: the arm end of each exhibition arm is connected to rubber blanket.
When the utility model uses, entirety stretches in pipeline, then slip slip ring makes exhibition arm open to exhibition arm arm end to be close to inside pipe wall, exhibition arm open angle is obtained by rotary angle transmitter measurement, each proximity Hall switch represents a height and position respectively simultaneously, by slip ring is responded between magnetic and proximity Hall switch, the length of slip ring distance circle seat can be obtained, be beneficial to principle of triangulation like this and can calculate bore path length fast.The utility model can realize the measurement of bore quickly and easily, and has higher measuring accuracy.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
