Description
Technical field
This utility model relates to a kind of Material Testing Machine Experiments of Machanics fixture, belongs to jig Design technical field.
Background technology
Material Testing Machine, is to measure the mechanical performance of metal material, nonmetallic materials, machine components, engineering structure etc., the fine measuring instrument of processing performance under various conditions, environment.Be used for metal and nonmetallic stretching, shear, the Resarch on A New Type research of the item such as tear.In Experiments of Machanics due to test specimen and machine misalign bring additional bending moment, affect experimental result.It is typically employed in test specimen two end surface and posts pad, to eliminate the impact of the moment of flexure occurred in process of the test.Being required for posting pad on every piece of test specimen, carry out mechanical test the most again, experiment takes off pad after terminating, and work efficiency is relatively low, and error is not easily controlled.Any good ameliorative way is not also had for this situation, is therefore badly in need of the defect wanting a kind of material mechanical test machine Experiments of Machanics fixture to overcome existing apparatus.
Utility model content
The purpose of this utility model is to provide a kind of Material Testing Machine Experiments of Machanics fixture, to solve the problems such as current material testing machine inefficiency, error be wayward.
This utility model is realized by techniques below scheme: a kind of Material Testing Machine Experiments of Machanics fixture, including voussoir 1, location screw 2, sliding wedge 4；Voussoir 1 top offers screwed hole 8, groove 9 is offered on voussoir 1, dovetail groove 10 is offered in groove 9, voussoir 1 sidepiece is installed on spring and hangs pin 7, sliding wedge 4 top is provided with rule 3, is installed on dovetail 6 bottom sliding wedge 4, and sliding wedge 4 is provided with annular knurl section 5, in sliding wedge 4 coordinates, with dovetail groove 10, the groove 9 being arranged on voussoir 1 by dovetail 6, location screw 2 is arranged on voussoir 1 top by screwed hole 8.
It is hemispherical bottom described location screw 2.
The operation principle of a kind of Material Testing Machine Experiments of Machanics fixture is: before the test, by rotating location screw 2, location screw 2 is spinned and is moved downward, bottom the screw 2 of location, hemispherical 11 contact with the bevel point of sliding wedge 4, power is reached on the inclined-plane of sliding wedge 4 by location screw 2, promotes the sliding wedge 4 groove 9 external movement to voussoir 1；The rule 3 of sliding wedge 4 upper end may determine that compensation thickness by aliging with the front end face of voussoir 1, and there is annular knurl section 5 sliding wedge 4 side, can increase the stiction between sliding wedge 4 and test specimen.
This utility model has the advantages that
1, this device can improve in Experiments of Machanics due to test specimen and machine misalign bring additional bending moment, improve the reliability of experiment；
2, this device can carry out the Experiments of Machanics of different-thickness composite member, improves the popularity of experimental applications；
3, the rule of sliding wedge upper end can accurately provide compensation dosage, improves the accuracy of experiment；
4, the annular knurl end face of sliding wedge can increase the stiction between test specimen and fixture, improves the stability of experiment；
5, voussoir is installed by dovetail groove with sliding wedge, can improve experiment stationarity of motion in compensation process.

Fig. 3 is sliding wedge structural representation of the present utility model；
Fig. 4 is location of the present utility model bolt structure schematic diagram.
Figure is respectively numbered: 1: voussoir, 2: location screw, 3: rule, 4: sliding wedge, 5: annular knurl section, 6: dovetail, 7: spring hang pin, 8: screwed hole, 9: groove, 10: dovetail groove, 11: hemispherical.
Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment, the utility model is described in further detail, but content of the present utility model is not limited to described scope.
Embodiment 1: as shown in Figure 1-2, a kind of Material Testing Machine Experiments of Machanics fixture, including voussoir 1, location screw 2, sliding wedge 4；Voussoir 1 top offers screwed hole 8, groove 9 is offered on voussoir 1, dovetail groove 10 is offered in groove 9, voussoir 1 sidepiece is installed on spring and hangs pin 7, sliding wedge 4 top is provided with rule 3, is installed on dovetail 6 bottom sliding wedge 4, and sliding wedge 4 is provided with annular knurl section 5, in sliding wedge 4 coordinates, with dovetail groove 10, the groove 9 being arranged on voussoir 1 by dovetail 6, location screw 2 is arranged on voussoir 1 top by screwed hole 8.
It is hemispherical bottom the screw 2 of location.
