Abstract
This is a draw & twist clamping device, which can achieve the rigid coupling between the hydraulic pressure clamping head and the piston rod, while the coupling between the hydraulic pressure clamping head and the straight actuator will not loose as the tension and the twisting test are conducted, so that the dynamic properties are improved. This device comprises a pair of fastened fixture blocks. Also, the half slots are set respectively on the two fixture blocks. In addition, two sections of the female screws are arranged on the half slot. The threads thereof are opposite to each other. The two half slots with the female screws jointly construct two sections of the screw holes, of which the spirals are opposite to each other.
Description
Technical field
The utility model relates to the electro-hydraulic servo dynamic testing machine, relates in particular to drawing of electro-hydraulic servo dynamic testing machine and turns round chuck.
Background technology
The dynamic pull and torsion test machine of electro-hydraulic servo is the pull and torsion test that is used for material or member, when promptly sample being applied axial tension and compression test power, also to apply radially twisting test power to sample, in this case, the connection meeting between hydraulic chuck and the linear actuator may occur becoming flexible owing to the existence of twisting test power.
Summary of the invention
The utility model has proposed a kind of drawing at deficiency of the prior art and has turned round the chuck hookup, it can be in the same place hydraulic chuck and piston rod rigid connection, when doing tension and compression and twisting test at the same time, becoming flexible can not appear in the connection between hydraulic chuck and the linear actuator, improves its dynamic property.
This programme is realized by following technical measures: it comprises a pair of fixture block that can tighten together, correspondence is provided with half slot respectively on two fixture blocks, half slot is provided with two sections opposite internal threads of rotation direction, and tapped two half slots constitute the screw of two sections rotation direction opposite threads jointly.
The beneficial effect of this programme can be learnt according to the narration to such scheme, the fixture block that the utility model setting and chuck on dynamic testing machine are connected with piston rod thread, realize the rigid connection of hydraulic chuck and piston rod, like this when doing tension and compression and twisting test, becoming flexible can not appear in the connection between hydraulic chuck and the linear actuator, improves its dynamic property., so the utility model is compared with prior art, has realized technical purpose.
The concrete characteristics of this programme also have between the described fixture block and connect with bolt.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described in further detail.
Fig. 1 turns round chuck hookup synoptic diagram for drawing.
Fig. 2 is the right view of Fig. 1;
Fig. 3 is the vertical view of Fig. 2;
Among the figure, 1, fixture block, 2, screw thread, 3, screw, 4, bolt, 5, half slot.
Embodiment
Shown in Fig. 1～3, the utility model comprises a pair of fixture block that can tighten together 1, correspondence is provided with half slot 5 respectively on two fixture blocks 1, half slot 5 is provided with two sections opposite internal threads 2 of rotation direction, and tapped two half slots constitute the screw 3 of two sections rotation direction opposite threads jointly.Fixedly connected between the described fixture block with bolt 4.
During making, a pair of fixture block is done as a wholely to process fastening these two threaded holes that fixture block is used, and the screw thread that connects with chuck and piston rod respectively, wherein an end is left-handed, the other end is dextrorotation.An also desirable block of material integral body is made the screw thread that connects with chuck and piston rod, and the threaded hole that supplies fastening usefulness, is cut into two from the centre then.
During use, utilize two sections fan-shaped screw threads in the half slot to be connected with piston rod, also have certain clearance between two fixture blocks, can tighten, eliminate thread pitch, realize fastening being rigidly connected by bolt with chuck.After using a period of time, thread abrasion, fastening bolt is further eliminated the gap again, can continue to use.
Claims (2)
1, a kind of drawing turned round the chuck hookup, it is characterized in that it comprises a pair of fixture block that can tighten together, correspondence is provided with half slot respectively on two fixture blocks, half slot is provided with two sections opposite internal threads of rotation direction, and tapped two half slots constitute the screw of two sections rotation direction opposite threads jointly.
2, according to claim 1 drawing turned round the chuck hookup, it is characterized in that, connects with bolt between the described fixture block.
