For solving the problems of the technologies described above, the utility model provides a kind of to be comprised pedestal 1, groove 2, regulates device for fastening and keeper for the calibrating installation to on-gauge plate clamping and precision positioning on horizontal metroscope; Described pedestal 1 is fixed on the horizontal metroscope workbench by described keeper; Described groove 2 is fixed on described pedestal 1; Described adjusting device for fastening is arranged on described groove 2.
Further, have positioning runner 6 on described pedestal 1.
Further, described groove 2 cell wall is on one side offered bolt fastening hole, and the another side cell wall is offered mounting hole; The center of circle of described bolt fastening hole and the center of circle of described mounting hole are in same level.
Further, described adjusting device for fastening comprises adjustable splint 3 and adjustable splint device for fastening 7; Described adjustable splint 3 is arranged in the middle of described groove 2 by described adjustable splint device for fastening 7; Offer the hole in the middle of described adjustable splint 3; Described adjustable splint device for fastening 7 is fastening bolt.
Further, described fastening bolt passes described bolt fastening hole and inserts in the hole of offering in the middle of described adjustable splint 3, is axially movable worm drive.
Further, described keeper is arranged in the positioning runner 6 of pedestal 1, comprises slip bolt 4 and slip bolt nut 5; Described slip bolt 4 is connected with described slip bolt nut 5.
The utility model provides is used on horizontal metroscope the pedestal of the calibrating installation of on-gauge plate clamping and precision positioning is seen by the location and is fixed on the horizontal metroscope workbench, be fixed tightly on the measurement pedestal by the adjusting device for fastening on-gauge plate that size is less that is arranged on groove, be not easy to cause departing from and Mechanical Moving of on-gauge plate when carrying out the adjusting of flex point in measuring operation, can measure accurately and effectively less than the on-gauge plate below 14mm gauge.
Description of drawings
Fig. 1 is used on horizontal metroscope calibrating installation vertical view to on-gauge plate clamping and precision positioning for what the utility model embodiment provided;
Fig. 2 is used on horizontal metroscope calibrating installation left view to on-gauge plate clamping and precision positioning for what the utility model embodiment provided;
Fig. 3 is used on horizontal metroscope calibrating installation front view to on-gauge plate clamping and precision positioning for what the utility model embodiment provided.
Embodiment
Referring to Fig. 1-3, the utility model embodiment provides a kind of on horizontal metroscope to the calibrating installation of on-gauge plate clamping and precision positioning, it comprises pedestal 1, groove 2, regulates device for fastening and keeper.Pedestal 1 is fixed on the horizontal metroscope workbench by keeper.Have positioning runner 6 on pedestal 1.Groove 2 is fixed on pedestal 1.Regulating device for fastening is connected with groove 2.Regulate device for fastening and comprise adjustable splint 3 and adjustable splint device for fastening 7.Boring is arranged in the middle of adjustable splint 3.Groove 2 cell wall is on one side offered bolt fastening hole, and the another side cell wall is offered bolt fastening hole; The center of circle of bolt fastening hole and the center of circle of mounting hole are in same level; Bolt fastening hole is used for installing adjustable splint 3, and mounting hole is used for stretching into conveniently of erecting tools.Fastening bolt passes bolt fastening hole and inserts in the hole of offering in the middle of adjustable splint 3, is axially movable worm drive, rotates but fastening bolt can not drive adjustable splint 3.Adjustable splint 3 is used for clamping detected on-gauge plate, is arranged on groove 2 by adjustable splint device for fastening 7 middle.Keeper is arranged in the positioning runner 6 of pedestal 1, comprises slip bolt 4 and slip bolt nut 5.Slip bolt 4 is connected with slip bolt nut 5.
With a thicker square alloy sheets as pedestal 1, will be on horizontal metroscope, the pedestal 1 of the calibrating installation of on-gauge plate and precision positioning being lain in a horizontal plane in the centre of horizontal metroscope workbench, mill out three positioning runners on pedestal 1, four holes are bored in the centre.In addition, process a groove 2, four holes and tapping are also bored in groove 2 bottoms, then utilize sunk screw that groove 2 and pedestal 1 is firmly fixing.Pedestal 1 be on horizontal metroscope to the core component of the calibrating installation of on-gauge plate and precision positioning, it is the assurance of whole utensil stability, so the plane planeness of pedestal 1 has certain technical requirement, guarantee during processing and fabricating that its pedestal 1 flatness is not more than 0.003mm, weight requires to be not more than 1Kg to reach stability requirement, and surfaceness is less than Ra0.10 μ m.Select an on-deformable alloy sheets of block of material as adjusting plate 3, middle boring.Groove 2 cell wall is on one side offered bolt fastening hole, and the another side cell wall is offered bolt fastening hole; The center of circle of bolt fastening hole and the center of circle of mounting hole are in same level; Bolt fastening hole is used for installing adjustable splint 3, and mounting hole is used for stretching into conveniently of erecting tools.Fastening bolt passes described bolt fastening hole and inserts in the hole of offering in the middle of adjustable splint 3, is axially movable worm drive, rotates but fastening bolt can not drive adjustable splint 3.The effect of adjustable splint 3 is exactly to clamp detected on-gauge plate, is arranged in the middle of groove with adjustable splint device for fastening 7.
That processes requires each workpiece reliable effect for the calibrating installation to on-gauge plate clamping and precision positioning on horizontal metroscope, coordinates and does not stay the gap, installs and regulates the device for fastening requirement reliably, firmly.
