Brief description of the drawings
Fig. 1 is the structural representation (rotating shaft is positioned at rolling disc inside and dots) of a preferred embodiment of the utility model;
Fig. 2 is plan structure schematic diagram (dial gauge part is also not shown) embodiment illustrated in fig. 1;
Fig. 3 is the structural representation installing after stator embodiment illustrated in fig. 1.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is done to concrete introduction.
Shown in seeing figures.1.and.2, parallelism detecting device 100 of the present utility model comprises: dial gauge 10, leg 20, chassis 30, jack-post 40, rotating shaft 50, rolling disc 60, support column 70, limited block 80, cantilever 90.
Dial gauge 10 comprises: extension sleeve 12, the expansion link 13 that is arranged on extension sleeve 12 energy elastic telescopic being fixedly connected with for the dial plate 11 of display scale, with dial plate 11, the measuring head 14 that is arranged on expansion link 13 outboard end.Wherein, thus expansion link 13 can make mechanism action in dial plate 11 make the dial plate 11 can be according to the telescopic level instruction reading of expansion link 13 when flexible.
The total design concept of depth of parallelism device of the present utility model is that making the flexible direction of expansion link 13 is vertical direction (the actual axis C that is expansion link 13 is parallel to vertical direction), make the axis of rotation of solid of revolution part to be measured also vertically arrange and can rotate with this axis simultaneously, the now reading when reading measuring head 14 to the contact of different piece, judges the depth of parallelism of solid of revolution part to be measured.
Particularly, the number of leg 20 is more than or equal to 3, and the below that they are arranged on chassis 30 forms and supports chassis 30; Jack-post 40 is fixedly installed on the top on chassis 30, rotating shaft 50 is arranged in jack-post 40, rolling disc 60 forms axis A being rotationally connected perpendicular to surface level by rotating shaft 50 and jack-post 40, the number of support column 70 is more than or equal to 2, they and limited block 80 are all fixed on the end face of rolling disc 60, cantilever 90 one end are arranged on the end face on chassis 30, the other end is provided with the hole of passing through of passing for extension sleeve, the extension sleeve of dial gauge 10 also forms and is fixedly connected with it away from the one end on chassis 30 through cantilever 90, measuring head is positioned at the top of cantilever 90, and dial plate is positioned at cantilever 90 belows.
