Description
Technical field
The utility model relates to a kind of higher pair formula plug measuring appliance.
Background technology
Two dovetail class size detection special measurement instrument, see Fig. 1-3, comprise mobile plug 2 ', measure plug 1 ', base plate 4 ' and panel 3 ', described panel 3 ' and base plate 4 ' all are rectangular structure, the described base plate 4 of described panel 3 ' be fixed on ' on, described panel 3 ' on have the slippage slot 5 of strip ', described slippage slot 5 ' two ends are arc structures; Described base plate 4 ' slippage slot 5 ' an end below the position have one with unthreaded hole 6 ', described unthreaded hole 6 ' vertical with the one side that base plate 4 ' last area is big, described measurement plug 1 ' pass slippage slot 5 ' transition fit be installed in unthreaded hole 6 ' in; Described mobile plug 2 ' movably be installed in slippage slot 5 ' in.The two dovetail class size detection special measurement instrument of this kind are used wider in the dimension process that detects two dovetail class Shape Parts, accuracy of detection is also higher, but because mobile plug 2 ' be face with base plate 4 ' surface of contact to contact, make friction force between the two bigger, moving 2 ' time of plug with measurer, used ergometry is bigger, and causes that accuracy of detection decreases in the testing process.
Summary of the invention
For solving the problem that reduces with the precision of two dovetail class size detection special measurement instrument in measuring process, the utility model provides a kind of measuring accuracy high higher pair formula plug measuring appliance.
The technical solution of the utility model:
Higher pair formula plug measuring appliance, comprise mobile plug, measure plug, base plate and panel, described panel and base plate all are rectangular structure, and described panel is fixed on the described base plate, have the slippage slot of strip on the described panel, the two ends of described slippage slot are arc structures; The position of described base plate below an end of slippage slot has one and unthreaded hole, and the one side that area is big on described unthreaded hole and the base plate is vertical, and described measurement plug passes the slippage slot transition fit and is installed in the unthreaded hole; Described mobile plug movably is installed in the slippage slot, it is characterized in that: described mobile plug and base plate contact jaw are ball shapes.
Further, described unthreaded hole is fraising.
Further, described panel is fixedlyed connected by straight pin with base plate.
Each face of panel of the present utility model and base plate has certain flatness and roughness requirement, and each corresponding surface has certain depth of parallelism requirement.The one side that area is big on unthreaded hole on the base plate and the base plate has certain verticality requirement, and for fraising, certain roughness and deviation from circular from is arranged; With the measurement plug of corresponding specification requirement be its transition fit, like this, the measurement disc of measuring plug and base plate can reach the vertical requirement of corresponding specification.The upper surface of mobile plug and bottom surface also has certain verticality requirement, mobile plug and base plate contact jaw are ball shapes, make that the contact form of its base plate surface of contact is the higher pair contact of a contact, thereby the ergometry in the time of being reduced in slippage in the testing process and moving plug can further improve accuracy of detection.
In measuring process, as long as the part of two dovetails and so on shape is lain on the panel of higher pair formula plug measuring appliance described in the utility model, measure the plug place wherein simultaneously touching earlier, again mobile plug is moved to the another side contact of dovetail by the slippage slot in the panel, measure the physical size of dovetail with measurer, also can detect the error of perpendicularity value (gap of detecting two surface of contact with clearance gauge gets final product) of each shape face of dovetail and reference field simultaneously.
When using the utility model to measure, the verticality that the end face of twin-core rod and plug are measured between the disc is not got in touch with the part dimension measurement of two dovetails and so on shape, when detecting two dovetails and so on Shape Parts, as long as measure the distance of the measurement disc outer end of mobile plug to the measurement disc outer end of measuring plug; Simultaneously, because the twin-core rod all is inserted among the panel, its degree of freedom has been subjected to control, has changed unsteady detection problem; Mobile plug contacts with the point of base plate, and the ergometry when being reduced in slippage in the testing process and moving plug can further improve accuracy of detection.
Effect intentionally of the present utility model: measurement size precision height, and simple and reasonable, easy to use.
