Specific embodiment
Below with reference to the attached drawing in the utility model embodiment, the technical solution of the utility model is described further.
A kind of torsion testing machine, including pedestal 1, rotation scroll chuck 23, fixed scroll chuck 31, torsion device 21 and solid
Reservation 32,
Fixed bracket 22 is installed, the rear side of the rotation scroll chuck 23 is fixedly connected with shaft on the upside of the pedestal 1
24, the shaft 24 is rotatablely connected with fixed bracket 22, and the torsion device 21 is set on pedestal 1, output shaft and shaft
24 is coaxially connected,
The fixing seat 32 is installed on pedestal 1, solid by fixing axle 34 and fixing seat 32 on rear side of fixed scroll chuck 31
Fixed connection,
A trough of belt claw 5 is all had in three claws of the rotation scroll chuck 23 and fixed scroll chuck 31, it is described
The side of trough of belt claw 5 opens up slot 51.
As shown in Figure 1, torsion device 21 provides power and the detecting instrument etc. of torsion, metal wire rod 9 for torsion test
One end is clamped by rotation scroll chuck 23, and the other end is clamped by fixing scroll chuck 31, drives rotation three-jaw by torsion device 21
Chuck 23 reverses, and is tested for the property to metal wire rod 9.
For the metal wire rod 9 that is preferably fixedly clamped, as shown in fig. 6, the side of trough of belt claw 5 opens up slot 51, for holding
The bending 91 for setting metal wire rod 9 prevents bending 91 from blocking the gap between two claws of scroll chuck, influences to clamp.Such as Fig. 7
Illustrate the situation that bending 91 is placed in slot 51.As shown in figure 8, being the left view of Fig. 6, it is clear that slot 51 is located at band
Position on slot claw 5, Fig. 9 illustrate the situation that bending 91 is placed in slot 51.
Fig. 3 is the schematic diagram of three claw clamping metal wire rods 9, can be seen that bending 91 in figure and is placed in slot 51, one
Aspect is close proximity in the slot 51 of trough of belt claw 5, be will not influence drawing close to centre for three claws and is clamped metal wire rod 9；It is another
Aspect, in torsion test, bending is close proximity to the side of trough of belt claw 5, and metal wire rod 9 can be effectively prevented in three claws
