Described releasable connection structure comprises the first pin-and-hole being opened in the axis on front frock body part and extending along the longitudinal direction, releasable connection structure also comprises second pin-and-hole corresponding with the first pin-and-hole be opened on rear frock body part, is coated with connection pin in first, second pin-and-hole.
Described fixed structure comprises the outer square toes for being clamped by described chuck extended along the longitudinal direction.
Described driving groove coordinating with described nut body spline with the coincide driving key of inserting of the force groove on described nut body by extending along the longitudinal direction that its cell wall is arranged.
In the utility model, the technical scheme of testing machine is:
Testing machine, comprise chuck and nut experimental rig, nut experimental rig comprises frock body, frock body rear end is provided with the fixed structure for being fixedly connected with corresponding testing machine, the front end of frock body be provided with the confession respective nut body extended along the longitudinal direction coincide spline load driving groove.
Described frock body comprises the front frock body part of front and back split setting and rear frock body part, described fixed structure is arranged on described rear frock body part, described driving groove is arranged on described front frock body part, and described front frock body part passes through releasable connection anatomical connectivity on described rear frock body part.
Described releasable connection structure comprises the first pin-and-hole being opened in the axis on front frock body part and extending along the longitudinal direction, releasable connection structure also comprises second pin-and-hole corresponding with the first pin-and-hole be opened on rear frock body part, is coated with connection pin in first, second pin-and-hole.
Described fixed structure comprises the outer square toes clamped by described chuck extended along the longitudinal direction.
Described driving groove coordinating with described nut body spline with the coincide driving key of inserting of the force groove on described nut body by extending along the longitudinal direction that its cell wall is arranged.
The beneficial effects of the utility model are: make the fixed structure on frock body be connected with testing machine during use, the chuck of testing machine is no longer direct to exert a force to nut body, thus effectively prevent nut easily by problem that card is bad, driving groove is by coordinating to nut body power transmission with nut body spline, driving groove also not to nut body radial direction force, further ensure that nut body can not be bad by card.

Detailed description of the invention
The embodiment of testing machine is as shown in Fig. 3 ~ 8: comprise chuck and nut experimental rig, chuck belongs to prior art, its concrete structure no longer describes in detail, nut experimental rig comprises frock body, frock body comprises the front frock body part 5 of front and back split setting and rear frock body part 6, rear frock body part is provided with the fixed structure for being fixedly connected with chuck, fixed structure comprises the outer square toes 7 for being clamped by chuck extended along the longitudinal direction, outer square toes front end has been wholely set terminal pad 8, front frock body part 5 passes through releasable connection anatomical connectivity on terminal pad, front frock body part is the cover shape structure that axis extends along the longitudinal direction, releasable connection structure comprises the first pin-and-hole 10 that the axis be opened on front frock body part extends along the longitudinal direction, releasable connection structure also comprises second pin-and-hole 9 corresponding with the first pin-and-hole be opened on rear frock body part, first, be coated with in second pin-and-hole and connect pin 4.The front endoporus of frock body part and the front face of connecting plate surround driving groove, the inner hole wall of front frock body part is provided with the driving key 3 extended along the longitudinal direction, during use, self-locking nut coincide in the driving groove of the front frock body part of loading, driving key coincide in the force groove of inserting on the nut body of self-locking nut, thus realizes driving groove and coordinate with nut body spline.
During use, nut experimental rig is vertically arranged, the outer square toes of frock body part after the chuck clamping of testing machine, by install in first, second pin-and-hole connect pin front frock body part is connected to after on frock body part, the nut body of self-locking nut is put into the endoporus of front frock body part, so just achieve the transmission between chuck and self-locking nut, just can carry out the locking test of self-locking nut at the other end construction bolt of testing machine.Front frock body part passes through releasable connection anatomical connectivity on rear frock body part, like this when testing the self-locking nut of different model, only need change front frock body part, the front frock body part of various model has the driving groove of different pore size respectively, various front frock body part can use common rear frock body part, save frock cost on the one hand, also eliminate in addition and need to unclamp this step of chuck, simplify the Renewal process of nut experimental rig, before connecting pin realization, rear frock body part connects, before needs are changed during frock body part, to dismantle connection pin, take off front frock body part, connect the quick-detachment that pin achieves front frock body part, when current frock body part takes off simultaneously, do not need to overturn front frock body part, self-locking nut can direct falling by the endoporus of front frock body part from top to bottom, the taking-up process of self-locking nut is simple and convenient, this nut experimental rig is applicable to the test of large-scale nut very much.
In other embodiment of this testing machine: fixed structure may not be outer square head structure, such as fixed structure is the column structure for chuck clamping; Releasable connection pin can also be replaced by other releasable connection structures such as bolt fastening structures; Certain forward and backward frock body part can also be one-body molded; When this nut experimental rig is applied to the test of common outer square nut, the driving key on driving groove also can not be established, now driving groove cross sectional shape can with square structure in foreign side nut shape adaptation.
The embodiment of nut experimental rig is as shown in Fig. 3 ~ 8: the embodiment of nut experimental rig is identical with the nut experimental rig described in above-mentioned each testing machine embodiment, is not described in detail in this.
