Abstract
The utility model relates to the technical field of machinery, in particular to an improved nut fixing clamp for a tester. The improved nut fixing clamp for the tester comprises a nut fixing clamp body, a parallel groove or step groove in the longitudinal direction is formed in the middle of the nut fixing clamp body, a through hole is formed in the bottom center of the parallel groove or step groove, and two groove holes are formed in the nut fixing clamp body. Compared with the prior art, a track type annular countersink is changed into the parallel groove or step groove, so that nut arranging and clamping are achieved, a nut is conveniently clamped, time for relative tests on a friction coefficient of a bolt is saved, and the efficiency of the relative tests on the friction coefficient of the bolt is improved.
Description
Technical field
The utility model relates to field of mechanical technique, specifically a kind of improved testing machine nut stationary fixture.
Background technology
On ZWICK testing machine, while carrying out the dependence test of bolt coefficient of friction, need fixture to be fixed nut.But due to, grip of testing machine is racetrack annular counter bore structure, nut put area space is too little, is not easy to the clamping of nut, thereby causes the testing time to be elongated, and has affected testing efficiency.
Therefore, need to design a kind of improved testing machine nut stationary fixture that can be convenient to nut clamping.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of improved testing machine nut stationary fixture that can be convenient to nut clamping is provided.
In order to achieve the above object, the utility model has designed a kind of improved testing machine nut stationary fixture, comprise nut stationary fixture body, it is characterized in that: nut stationary fixture body middle part is provided with longitudinal parallel slot or step groove, the bottom center of parallel slot or step groove is provided with through hole, and nut stationary fixture body is provided with two slotted eyes.
The connecting line at two described slotted eye centers is vertical with the center line of described step groove.
The connecting line at two described slotted eye centers is vertical with the center line of described parallel slot.
The bottom of described slotted eye is circular arc.
The utility model compared with the existing technology, the racetrack annular counterbore of placing nut is modified to parallel slot or step groove, solve the problem that nut is placed clamping, be convenient to nut clamping, thereby save the time of bolt coefficient of friction dependence test, improved the efficiency of bolt coefficient of friction dependence test.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is upward view of the present utility model.
Referring to Fig. 1 and Fig. 2,1 is nut stationary fixture body; 2 is parallel slot; 3 is through hole; 4 is slotted eye.
The specific embodiment
Now by reference to the accompanying drawings the utility model is described further.
Referring to Fig. 1 and Fig. 2, the utility model comprises nut stationary fixture body.Nut stationary fixture body 1 middle part is provided with longitudinal parallel slot 2 or step groove, and the bottom center of parallel slot 2 or step groove is provided with through hole 3, and nut stationary fixture body 1 is provided with two slotted eyes 4.
In the utility model, the connecting line at two slotted eye 4 centers is vertical with the center line of step groove or parallel slot 2.The bottom of slotted eye 4 is circular arc.
The racetrack annular counterbore of placing nut is modified to parallel slot 2 or step groove by the utility model, solve the problem that nut is placed clamping, be convenient to nut clamping, thereby saved the time of bolt coefficient of friction dependence test, improved the efficiency of bolt coefficient of friction dependence test.
