Embodiment
The first embodiment of the present invention, as shown in Figure 1, Woodruff key slots and keyways special measuring tool, comprises handle 1; Described handle two ends are equipped with surveys block standing groove 2; The survey block standing groove at described handle two ends connects go side respectively by bindiny mechanism and surveys block 3 and not-go-end survey block 4; Described go side survey block 3 is surveyed block 4 with not-go-end and is circle, its diameter is slightly less than the diameter of Woodruff key slots and keyways, the minimum limit of size that block 3 thickness is Woodruff key slots and keyways width is surveyed in go side, and not-go-end surveys maximum limit of size that block thickness is Woodruff key slots and keyways width (described go side survey thickness that block and not-go-end survey block be respectively Woodruff key slots and keyways lead to, stop smooth internal limit gage); Described go side is surveyed on end face that block 3 and not-go-end survey block 4 and is respectively equipped with at least one through hole 5; Described bindiny mechanism outside handle two ends, the surface of revolution is arranged the mounting hole 6 running through and survey block standing groove upper and lower wall, be provided with in described mounting hole 6 with mounting hole 6 with the use of straight pin 7.Realize go side survey block by being inserted in mounting hole 6 and through hole by straight pin 7, not-go-end survey block is connected to handle two ends.
During use, inserting in Woodruff key slots and keyways by first go side being surveyed block 3, extracting go side out and surveying block, then not-go-end is surveyed in block insertion Woodruff key slots and keyways; Judge that the standard that Woodruff key slots and keyways is qualified is: go side is surveyed block and needed to insert Woodruff key slots and keyways, not-go-end surveys block can not insert Woodruff key slots and keyways, and now, then workpiece is qualified.Survey due to go side thickness that block and not-go-end survey block to be respectively Woodruff key slots and keyways and to lead to, stop smooth internal limit gage, only need go side to survey block to need to insert Woodruff key slots and keyways, not-go-end surveys block can not insert Woodruff key slots and keyways, then represent that Woodruff key slots and keyways width is between maximum limit of size and the minimum limit of size.
The second embodiment of the present invention, described in Fig. 2, described bindiny mechanism outside handle two ends, the surface of revolution is arranged the first threaded hole 8 running through and survey block standing groove upper and lower wall, be provided with in described first threaded hole 8 with the first threaded hole 8 with the use of screw 9.Adopt the connected mode of threaded hole and screw, make go side survey block and not-go-end survey block and be more firmly connected to and survey in block standing groove.
The present invention to for go side being surveyed block, not-go-end survey block be connected to handle two ends survey connected mode in block standing groove except the pin of the first embodiment can be adopted to connect, also can adopt being threaded of the second embodiment, and key connection.
Connect owing to only adopting pin or be threaded go side surveyed block, not-go-end is when surveying that block is dismountable is connected to handle two ends, inadequate to survey block clamping force, survey block easily to loosen, measure inconvenient, for the problems referred to above, the third embodiment of the present invention, described in Fig. 3-Fig. 4, the side wall surface of described survey block standing groove armrest handle 1 side is provided with the second fluting 10, the outer surface of revolution of described handle be provided with run through the second fluting 10 the second threaded hole 11, second threaded hole 11 in be provided with the second screw 11 with the use of housing screw 12.Utilization screws housing screw 12, regulates the size of the second fluting 10, thus block is surveyed in clamping go side further, not-go-end surveys block.
Preferably, described go side survey block 3 is surveyed on block 4 end face with not-go-end and is evenly equipped with three through holes 5 respectively, and go side is surveyed the circle that three through hole centers of circle on block end face surround and surveyed block concentric with go side, the circle that three through hole centers of circle on not-go-end survey block end face surround and not-go-end survey block concentric.Survey on block end face due to go side survey block and not-go-end and be evenly equipped with three through holes respectively; When using Woodruff key slots and keyways special measuring tool first, logical, not-go-end surveys block because of after wearing and tearing scrap, and can unclamp straight pin, allow survey after block rotates 120 ° and again clamp with straight pin, still can continue to use, and 120 ° twice can be rotated, make the life-span of Woodruff key slots and keyways special measuring tool improve three times.
Preferably, described bindiny mechanism outside handle two ends, the surface of revolution is provided with the mounting hole running through and survey the upper and lower wall of block standing groove, and in this mounting hole, the surface of revolution is provided with some first grooves, and the first channel section is triangular in shape; Be provided with in described mounting hole with mounting hole with the use of straight pin, the outer surface of revolution of this straight pin is provided with some elastic flanges 14 used with the first groove fit; It should be noted that in the mounting hole except handle two ends and need to arrange some first grooves, block is surveyed in same go side all needs to arrange second groove corresponding with the first groove with the through hole that not-go-end is surveyed on block.Because the surface of revolution in mounting hole is provided with some first grooves, and the first channel section is triangular in shape; Be provided with in described mounting hole with mounting hole with the use of straight pin, the outer surface of revolution of this straight pin is provided with some elastic flanges used with the first groove fit; When being inserted in mounting hole by straight pin, elastic flange snaps among the first groove in mounting hole and through hole, the second groove, and straight pin can not be rotated.
Block is surveyed except can measuring the keyway minimum limit of size in go side, can also measure the keyway degree of depth after converting:
H
min＝d+√(d
2-b
2)-N
max
H
max＝d+√(d
2-b
2)-N
min
In above-mentioned formula, H is the keyway degree of depth; D is the radius of keyway place axle; B is the half of width of keyway; N is the distance to axle cylindrical at the bottom of keyway.
