Embodiment
The implementation of testing machine is for example shown in Fig. 3~8：Including chuck and nut experimental rig, chuck belongs to prior art, its
Concrete structure is no longer described in detail, and nut experimental rig includes frock body, and frock body includes the preceding frock sheet of front and rear split settings
Body portion 5 and rear frock body part 6, the fixed structure for being fixedly connected with chuck is provided with rear frock body part,
What fixed structure included extending along the longitudinal direction is used to be wholely set connection by the outer square toes 7 of chuck clamping, outer square toes front end
Disk 8, preceding frock body part 5 are connected in terminal pad by releasable connection structure, and preceding frock body part is axis before and after
The set shape structure of direction extension, the axis that releasable connection structure includes before being opened on frock body part extend along the longitudinal direction
The first pin-and-hole 10, releasable connection structure also includes being opened in second corresponding with the first pin-and-hole on rear frock body part
Pin-and-hole 9, connecting pin 4 is coated with first, second pin-and-hole.The endoporus of preceding frock body part and the front face of terminal pad surround
Driving groove, the driving key 3 extended along the longitudinal direction is provided with the inner hole wall of preceding frock body part, in use, self-locking nut
It coincide before being fitted into the driving groove of frock body part, driving key coincide inserting in the force groove on the nut body of self-locking nut
In, so as to realize that driving groove coordinates with nut body rotation stop.
In use, nut experimental rig is vertically arranged, the outer square toes of frock body part after the chuck clamping of testing machine, lead to
Cross in first, second pin-and-hole and install after preceding frock body part is connected to by connecting pin on frock body part, by self-locking
The nut body of nut is put into the endoporus of preceding frock body part, the transmission being so achieved that between chuck and self-locking nut,
The locking experiment of self-locking nut is can be carried out in the other end installation bolt of testing machine.Preceding frock body part passes through removable company
Binding structure is connected on rear frock body part, so when testing the self-locking nut of different model, frock sheet before need to only changing
Body portion, the preceding frock body part of various models have the driving groove of different pore size respectively, and various preceding frock body parts can
Using common rear frock body part, on the one hand to save frock cost, also eliminate in addition need to unclamp chuck this
Step, the Renewal process of nut experimental rig is simplified, realize that forward and backward frock body part connects by connecting pin, needing
Before changing during frock body part, connecting pin of dismantling, frock body part, connecting pin realize preceding work before removing
The fast quick-detach of body part is filled, while when current frock body part is removed, is not required to frock body part, self-locking spiral shell before overturning
Mother can fall in the endoporus by preceding frock body part directly from top to bottom, and the taking-up process of self-locking nut is simple and convenient,
This nut experimental rig is especially suitable for the experiment of large-scale nut.
In the other embodiments of this testing machine：Fixed structure may not be outer square head structure, such as fixed structure
For the cylindrical structure for chuck clamping；Releasable connection pin can also be bolted other releasable connection structure generations such as attachment structure
Replace；Certain forward and backward frock body part can also be integrally formed；When this nut experimental rig is applied to common outer square nut experiment
When, the driving key on driving groove can not also be set, and now the cross sectional shape of driving groove can be adapted to foreign side nut shape
Interior square structure.The implementation of nut experimental rig is for example shown in Fig. 3~8：The embodiment of nut experimental rig and above-mentioned each testing machine
Nut experimental rig described in embodiment is identical, will not be described in detail herein.
