Detailed description of the invention
nullThe embodiment of a kind of testing machine is as shown in figures 3-8: include chuck and self-locking nut Special testing device，Chuck belongs to prior art，Its concrete structure no longer describes in detail，Self-locking nut Special testing device includes assay device body，Assay device body includes front assay device body part 5 and rear assay device body part 4，It is provided with for fixing the fixed structure being connected with chuck on rear assay device body part 4，Fixed structure delay before including direction extend for by the outer square toes 6 of chuck clamping，Outer square toes 6 front end is connected with connection dish 7，Front assay device body part 5 is connected on connection dish 7 by releasable connection structure，Releasable connection structure includes the first bolt hole 8 that the axis being opened on front assay device body part 5 extends along the longitudinal direction and second bolt hole 10 corresponding with the first bolt hole 8 being opened on rear assay device body part 4，First bolt hole 8 and the second bolt hole 10 are coated with connecting bolt，The center position of front assay device body part 5 offers the driving groove for loading for the lock claw of corresponding self-locking nut，In the present embodiment, the lock claw of self-locking nut is 4，Therefore driving groove is cross recess 9，Front assay device body part 5 is run through before and after cross recess 9，During use，Each lock claw of self-locking nut is inserted in cross recess 9，Thus realize cross recess 9 and coordinate with self-locking nut spline.
During use, the outer square toes 6 of assay device body part 4 after the chuck clamping of testing machine, by on assay device body part 4 after installing connecting bolt in first, second bolt hole front assay device body part 5 being connected to, the lock claw of self-locking nut is inserted in cross recess 9, thus achieve the transmission between chuck and self-locking nut, other end clamp assay bolt at testing machine, it is possible to carry out the locking test of self-locking nut.Front assay device body part 5 is connected on rear assay device body part 4 by releasable connection structure, so when testing the self-locking nut of different model, only need to change front assay device body part 5, the front assay device body part 5 of various models is respectively provided with the driving groove of different pore size and kind, various front assay device body parts 5 can use common rear assay device body part 4, on the one hand frock cost is saved, additionally also eliminate the step for of needing to unclamp chuck, simplify the Renewal process of self-locking nut assay device, before being realized by connecting bolt, the connection of rear assay device body part, before needs are changed during assay device body part 5, dismantle connecting bolt, take off front assay device body part 5, connecting bolt achieves the fast quick-detach of front assay device body part 5.
In other embodiments of this testing machine, driving groove may not be cross recess, but with the lock claw of self-locking nut to adaptive groove structure；Fixed structure may not be outer square head structure, can be the column structure for chuck clamping；Connecting bolt can also be replaced by other releasable connection structures such as pin, screw；Forward and backward assay device body may not be what split was arranged, can be formed in one.
The embodiment of a kind of self-locking nut Special testing device is identical with the self-locking nut Special testing device described in above-mentioned each testing machine embodiment, and here is omitted.
