The through hole 5-1 that bar 2 passes, the lower end of described lower beam 2 is provided with bayonet lock 3, and the two ends of described bayonet lock 3 pass lower beam 2 and two ends pair
Claim, described sleeve 5 is provided with two guide grooves 4 coordinated with bayonet lock 3 two ends, is provided with bayonet lock 3 in the bottom of described sleeve 5
Two stopper slots 12 that two ends are spacing, the line between line and two stopper slots 12 between two described guide grooves 4 is cross
Intersect, between one of them described first guide groove and a described draw-in groove, another described first guide groove and another described card
Be provided with arcuate groove 13 between groove, described spill spin block 9 be provided with connecting hole 9-1, the top of described spill spin block 9 be provided with
The draw-in groove 8 that bayonet lock 3 coordinates, the bottom of described spill spin block 9 is provided with for motor that block 9 with lower beam 2 together with rotate is rotated
11, the axis of described spill spin block 9, sleeve 5, lower beam 2 and base 7 four coincides.
This stretching-machine lower beam self-locking device is by using the fit structure of bayonet lock 3 and stopper slot 12, by the card of lower beam 2 lower end
Pin 3 combines with the stopper slot 12 in sleeve 5, and bayonet lock 3 can enter corresponding matching part in running smoothly, coordinates
Precisely, it is to avoid artificial to lower beam 2 positioning action time the deviation that causes, fixed form simple possible, and applied widely.Its
In, the length that the two ends of bayonet lock 3 pass lower beam 2 two ends through lower beam 2 and two ends symmetry, i.e. bayonet lock 3 is equal, makes bayonet lock about 3
Two ends uniform force, to prevent in loading process it may happen that three-point bending phenomenon, it is ensured that block in drawing process
The intensity that pin is overall.The axis of spill spin block 9, sleeve 5, lower beam 2 and base 7 four coincides, and is not only convenient for installing, and guarantees fortune
Line stabilization.
As shown in Figure 1 and Figure 7, the output shaft of described motor 11 being provided with external splines 10, the bottom of described spill spin block 9 sets
Being equipped with internal spline 9-2, described external splines 10 matches with internal spline 9-2；Use the shape that external splines 10 matches with internal spline 9-2
Formula, can make motor 11 combine closely with spill spin block 9, thus avoids both axis runouts caused due to other combination
Problem, and there is no corresponding accessory, easy and simple to handle, improve installation effectiveness.
As shown in Figure 6, the quantity of described draw-in groove 8 is four, and four described draw-in grooves 8 are uniformly laid in outside connecting hole 9-1
Week, i.e. relative to the line of two draw-in grooves 8 be mutually perpendicular to, it is ensured that corresponding cooperation position does not changes, after last time has operated, so
The position that need not adjust spill spin block 9 directly carries out next operation, and operating efficiency is greatly improved.
As it is shown in figure 1, be provided with the range sensor for detecting bayonet lock 3 and the spacing of draw-in groove 8 in described draw-in groove 8
14, set the distance lower limit between bayonet lock 3 and draw-in groove 8, lower beam 2 can be effectively prevented during moving downward to spill spin block
9 extrude the damage that caused, the effective guarantee stability of whole device.
In the present embodiment, described range sensor 14 is IFRM type inductance type range sensor.
As in figure 2 it is shown, described base 7 be shaped as cuboid, four angles of described base 7 are provided with screw 6, warp
Base 7 can be fixed on matrix by the screw through screw 6, it is therefore prevented that is caused in stretching-machine work process rocks and shake
Dynamic, thus add the stability of base in drawing process.During actual fabrication, rounding can be respectively provided with on the four of base 7 angle
Angle, prevents from damaging experimenter.
As depicted in figs. 1 and 2, the upper end of described lower beam 2 is provided with sample fixing 1, it is simple to fixing sample.
In the present embodiment, described bayonet lock 3 cylindrically shaped, the length that bayonet lock 3 passes lower beam 2 two ends is equal, bayonet lock 3
No. 45 steels can be all used to make, to reach mechanical design requirements with sleeve 5.
In the present embodiment, the distance between described bayonet lock 3 and the bottom of lower beam 2 is 10cm～20cm.Preferably, described card
Distance between the bottom of pin 3 and lower beam 2 is 15cm.
In the present embodiment, the connected mode between described sleeve 5 and base 7 is for welding.
As a example by alloy sheet coupon is carried out extension test, illustrate the employing present invention to stretching-machine
Lower beam realizes self-locking, and its operating process is:
First, sheet alloy sample is arranged in sample fixing 1, through the screw through screw 6, base 7 is fixed on
On matrix, and motor 11 is arranged on matrix, spill spin block 9 is placed in connecting hole 9-1.Then, adjust lower beam 2 slowly to
Lower motion, when lower beam 2 will enter sleeve 5, by the way of fine setting, makes lower beam 2 move gradually downward along guide groove 4；When
When the bottom of lower beam 2 moves to the draw-in groove 8 of spill spin block 9, bayonet lock 3 is placed exactly in two of which draw-in groove 8, when range sensor 14
When setpoint distance being detected, lower beam 2 stops descending, and motor 11 starts.Then, that block 9 is rotated is suitable together with lower beam 2 for motor 11
After clockwise half-twist, motor 11 stops operating, and in spill spin block 9 rotation process, bayonet lock 3 slides along arcuate groove 13；Adjust
Lower beam 2 the most gradually moves along stopper slot 12, and limited groove 12 is blocked and stops moving up by final bayonet lock 3, and it is right to complete
The self-locking of stretching-machine lower beam.It is achieved thereby that the bayonet lock 3 on stretching-machine lower beam coordinates accurately with the stopper slot 12 in sleeve 5,
Finally according to concrete test request, metal material is carried out Mechanics Performance Testing.
After Mechanics Performance Testing completes, start motor 11 and make motor 11 that block 9 counterclockwise half-twist is rotated so that on
State the draw-in groove 8 used in auto-lock process and be exactly in starting position, in order to next time uses.Owing to being provided with four cards of symmetry
Groove 8, the most also can not allow spill spin block 9 half-twist counterclockwise, by two other draw-in groove 8 realize lower beam 2 fixing.
Stretching-machine lower beam self-locking device of the present invention is when actual fabrication, and the start and stop of the descending and motor 11 of lower beam 2 can be passed through
Controller realizes automatically controlling, to facilitate operation.
The above, be only presently preferred embodiments of the present invention, not impose any restrictions the present invention, every according to the present invention
Any simple modification, change and the equivalent structure transformation that above example is made by technical spirit, all still falls within skill of the present invention
In the protection domain of art scheme.
