The technical scheme provided by the utility model is that the sample clamp comprises a U-shaped clamp body as well as a track slab, a double-end stud and two wedged blocks, which are arranged inside the U-shaped clamp body, wherein the lower part of the U-shaped clamp body is connected with a pull rod of the high-temperature tensile testing machine; the upper-middle parts of two arms of the U-shaped clamp body are folded inwards; the two wedged blocks are respectively supported against smooth inclined planes on the inner sides of the upper-middle parts of the two arms of the U-shaped clamp body; a sample is clamped between the two wedged blocks; the track slab is positioned below the two wedged blocks; bosses matched with sliding chutes in the lower end surfaces of the two wedged blocks are arranged at the upper end of the track slab; and the upper end and the lower end of the double-end stud are respectively connected with the track slab and the U-shaped clamp body through threads with opposite screwing directions. Compared with a traditional clamp, the sample clamp disclosed by the utility model has the characteristics that the universality is strong, the test efficiency can be increased, and the test cost is reduced. In addition, when the sample clamp is used for testing, a hole is not needed to be punched in the clamping end of a platy sample; and the condition of deformation is not easily generated in the test process, so that the accuracy of the test result is ensured.
Description
Technical field
But the utility model relates to the high temperature tension test machine specimen holder of the multiple sample of a kind of clamping, belongs to technical field of measurement and test.
Background technology
The high temperature tension test machine is the device of the mechanical performance index of test material under hot environment, the sample that it is tested mainly contains two kinds, a kind of is plate tensile sample, a kind of is bar-shaped sample, at present, these two kinds of samples are to adopt different connected modes to be connected with the anchor clamps of testing machine: bar-shaped sample is connected with anchor clamps by screw thread, and the bare terminal end of plate tensile sample is provided with circular hole, is beneficial to the pin or the bolt that pass this circular hole sample is fixed on the anchor clamps.Because the anchor clamps of these two kinds of samples are not general, change the workload of anchor clamps when not only having increased test, prolong the test required time, and reduced the utilization factor of anchor clamps, thereby improved experimentation cost.In addition, adopt method that punching wears pin fixedly during plate tensile sample, can reduce the intensity of sample inevitably, in the tension test process, the circular hole place tends to deform, and influences the accuracy of test figure.
Summary of the invention
The purpose of this utility model is the high temperature tension test machine specimen holder that overcomes the deficiencies in the prior art, a kind of highly versatile is provided, to reduce the high temperature tension test cost, improves test efficiency and accuracy of experimental results.
The purpose of this utility model realizes with following technical proposals:
A kind of high temperature tension test machine specimen holder of highly versatile, comprise U-shaped chuck body and inner track plate, studs and two wedges thereof in the formation, the bottom of described U-shaped chuck body links to each other with the pull bar of high temperature tension test machine, receives in the middle and upper part of its two arm; Two wedges lean against on the smooth bevel of inboard, U-shaped chuck body two arm middle and upper part clamping sample between the two respectively; Described track plate is positioned at the below of two wedges, its upper end be provided with two wedge lower surfaces on the boss that is complementary of chute; The top and bottom of described studs are connected with U-shaped chuck body with the track plate respectively by the opposite screw thread of rotation direction.
The high temperature tension test machine specimen holder of above-mentioned highly versatile, the both sides of each wedge are provided with the eave tile plate, and the eave tile of described eave tile plate upper end is positioned at the horizontal channel on the wedge side, and the lower end is connected with the track plate.
The high temperature tension test machine specimen holder of above-mentioned highly versatile, the upper end of two arms of described U-shaped chuck body connects by gusset.
The utility model utilizes two wedge clamping samples, can make these anchor clamps adapt to different types of sample by changing wedge, compares with traditional anchor clamps, and these anchor clamps highly versatile can improve test efficiency, reduces experimentation cost.In addition, when using these anchor clamps to test, the bare terminal end of plate tensile sample need not punching, is difficult for deformation in the process of the test, has guaranteed accuracy of experimental results.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the A-A cut-open view;
Fig. 3 is the vertical view of Fig. 1.
Each label is among the figure: 1, pin; 2, gusset; 3, wedge; 4, track plate; 5, U-shaped chuck body; 6, eave tile plate; 7, bolt; 8, studs.
Embodiment
Referring to Fig. 1, Fig. 2, these anchor clamps mainly comprise: pin 1, gusset 2, wedge 3, track plate 4, U-shaped chuck body 5, eave tile plate 6, bolt 7, studs 8.
U-shaped chuck body 5 gabarits are cuboid, and the stressed consistance in each zone when guaranteeing to clamp avoids local pressure to concentrate and the destruction bulk strength.Outside below is and pull bar or the body connecting portion of high temperature tension test machine to process according to different connected modes; Track plate 4 and studs 8 are positioned at U-shaped chuck body 5 inner belows, and inboard, 5 liang of arm middle and upper parts of U-shaped chuck body is designed to smooth bevel, and two wedges 3 slide along the inclined-plane, require the inclined-plane that enough smooth finish is arranged.
Track plate 4 tops are for being provided with boss, and the chute of this boss and wedge 3 bottoms is used, and realize the restriction to wedge 3 tangential movement direction in U-shaped chuck body 5.
Gusset 2 is connected with U-shaped chuck body 5 by the pin 1 of two interference fit, strengthens the intensity of U-shaped chuck body 5, can improve the intensity of these anchor clamps.
These anchor clamps are the plate grips for the design of high temperature tension test machine, also applicable under the normal temperature, by changing the tension test that wedge also can be used for bar, therefore have good versatility.
Installation and application, at first anchor clamps are installed on the pull bar of high temperature tension test machine (or in other mechanism), reverse rotation studs 8 descends track plate 4, and wedge 3 follow-up units such as grade glide together, can open wedge, it is middle that tensile sample is put into two wedges 3, is rotated in the forward studs 8, makes track plate 4 promote two wedges 3 and constantly rise, sample is clamped and pretightning force is provided by the inclined-plane, so far sample installs.
In this example, wedge adopts 60 ° of angles of wedge (side that wedge 3 is corresponding with U-shaped chuck body 5 inboard smooth bevels and the angle of bottom surface), the clamping surface of wedge 3 and steel plate friction factor are more than 0.57, because the angle of wedge is selected between 45 to 90 degree, the pass between wedge angle and clamping surface and the steel plate coefficientoffriction is μ〉cot θ, wedge angle is more big, then stroke is more long, grip size is more big, otherwise then stroke is more short, and corresponding grip size is more little.To consider factors such as bulk, sample thickness, friction factor when therefore selecting wedge angle.
