China utility model patent ZL92214122.3 discloses a kind of outside micrometer error of indication testing tool, and it is made up of positioning regulating mechanism and clamping device, and clamping device is made up of last holding frame and following holding frame; The two end is a clamp port, and the other end is hinged, has a mind to the horizontally-guided groove in the body of rod side of last holding frame; Positioning regulating mechanism is made up of the seat of honour, following and locating shaft; Following seat is connected on the gathering sill of holding frame, and can be along this fluted shaft to moving or being fixed by fixture, and the seat of honour is connected with following through the axis of guide on following; And can move up and down or fix along the axis of guide by fixture; Locating shaft is installed on the seat of honour, can axially move forward and backward or fixed by fixture along it, and the front end of locating shaft is equipped with steel ball.Adopt this scheme, though can the error of indication of milscale be detected because its coupling member is more and since the various foozles of each member cause in the engagement process connection built on the sand, certainly will reduce the precision that indicating value detects.
Summary of the invention
Be to solve the deficiency that exists in the prior art, the utility model provides a kind of large-scale outside micrometer error of indication testing tool that can realize that the error of indication to milscale accurately detects, and it is simple in structure, processing ease.
For realizing above-mentioned purpose; The large-scale outside micrometer error of indication testing tool of the utility model; Comprise clamping device and the positioning regulating mechanism that is equipped with clamping device, the test rod that described positioning regulating mechanism comprises supporting seat, spins with the supporting seat screw thread, described clamping device comprise support and locking pull bar; When accuracy detection; The support that is connected with the chi frame of milscale location, through being connected of the locking pull bar that is connected with the chi frame, the detection position that the supporting seat locking positioning can be contacted with the micrometric screw of milscale in the detection end that makes test rod.
As the qualification to aforesaid way, the screw rod that described locking pull bar comprises holder, is connected with holder is provided with first set nut on screw rod.
As further qualification, be provided with the U-shaped hole that supplies test rod to pass through on the top of support to aforesaid way.
Further qualification as to aforesaid way is connected with second set nut on test rod.
As the qualification to the utility model, holder is provided with the T shape chute that the nut to screw rod clamps.
As the qualification to the utility model, the detection end of described test rod is a semisphere.
As the qualification to aforesaid way, described support has with milscale chi frame and carries out the hook portion that hook is connected with the locking pull bar.
As further qualification to aforesaid way, the hook chamber that described hook portion has C shape.
Adopt technique scheme; Only pass through the cooperation that is connected of support and locking pull bar; In detection end that makes test rod and the detection position that the micrometric screw of milscale can contact, the position of the test rod when detecting is confirmed, unique the supporting seat locking positioning, the small variations when each web member of having avoided causing because of error connects; It is simple in structure, and is easy to use.
