Description

Arrangement for measuring verticality

Technical field

The utility model relates to the product detection field, is specially a kind of arrangement for measuring verticality.

Background technology

For some cylindrical works, vertical requirement generally need to be satisfied with cylinder in its bottom surface, directly is not used for measuring verticality in existing measurer, and is inconvenient to the detection of its verticality, easily produces larger error.

Summary of the invention

In order to address the above problem, the utility model provides a kind of arrangement for measuring verticality, and it can detect verticality fast and accurately, and error is little.

its technical scheme is such: it comprises base, it is characterized in that, the V-type seat is installed on described base, be provided with the coarse positioning seat of corresponding described V-type seat on described base, be provided with the coarse positioning detection head on described coarse positioning seat, described coarse positioning seat two ends are symmetrically arranged with measuring seat, by turning axle, movable measuring staff is installed on described measuring seat, be provided with spring between described movable measuring staff and described measuring seat, described movable measuring staff one end is provided with movable measuring head, the described movable measuring staff other end connects the measuring head of stem-winder, be provided with dismountable calibrating device on described V-type seat.

It is further characterized in that, is symmetrically arranged with four positioning supports seats on described V-type seat; Described V-type seat is provided with quick holder on one side, is provided with quick clip on described quick holder.

after adopting structure of the present utility model, the V-type seat is installed on base, be provided with the coarse positioning seat of corresponding V-type seat on base, be provided with the coarse positioning detection head on the coarse positioning seat, coarse positioning seat two ends are symmetrically arranged with measuring seat, by turning axle, movable measuring staff is installed on measuring seat, be provided with spring between movable measuring staff and measuring seat, movable measuring staff one end is provided with movable measuring head, the movable measuring staff other end connects the measuring head of stem-winder, first with calibrating device, stem-winder is calibrated, by V-type seat and coarse positioning seat, workpiece is located, movable measuring staff change stem-winder reading by two ends detects verticality fast and accurately, error is little.
