Description
Technical field
The present invention relates to small drill drift creepage testing equipment field.
Background technology
The material mechanical performance method of testing of small drill drift creepage test method to be a kind of with tiny sample be object, conventional test methods can be replaced to obtain the croop property parameter of material, minimum owing to testing sample used, the croop property test aspect of bearing device has huge engineer applied to be worth under arms.
The vent method of current creep test has two kinds substantially: one adopts bottom ventilation, top gathers the method for displacement data, the method ventilation is separated with displacement acquisition, indirectly displacement data is obtained by the displacement of measuring test unit top, the displacement data that the method is measured is not direct displacement data, there is larger error.Another method is the method adopting top ventilation, and the method ventilation device is complicated, and blanket gas utilization ratio is lower.
Summary of the invention
The object of the present invention is to provide a kind of air-breather for small drill drift creepage test, while ventilation, the displacement of test is measured, simplified apparatus structure.
Technical scheme of the present invention is:
For the air-breather of small drill drift creepage test, comprise main snorkel, draft tube and bottom seal device, one end of draft tube is connected laterally at the position of the lower middle of main snorkel and is communicated with main snorkel, the end, upper end of main snorkel is provided with external thread, and the lower end of main snorkel is provided with internal thread; The middle part of bottom seal device is vertically provided with the preformed hole suitable with the diameter of parts to be measured, preformed hole is through hole, the outside of the first half of bottom seal device is provided with the external thread with the lower end internal thread adaptation of main snorkel, the latter half of bottom seal device is columniform cylinder table, and the external diameter of cylinder table is greater than the diameter of preformed hole.
The bottom of bottom seal device is provided with flat recess.
Draft tube is vertical with main snorkel.
Draft tube is connected with main snorkel one.
The external diameter of cylinder table equals the external diameter of main snorkel.
The present invention proposes a kind of air-breather for small drill drift creepage test, comprises main snorkel, draft tube and bottom seal device.Relative to prior art; the invention has the beneficial effects as follows: air-breather and displacement measuring device can be simplified; can measure the displacement of test while ventilation, simplify small drill drift creepage test unit, while directly measuring sample displacement, improve the utilization ratio of blanket gas.This device is easy to manufacture processing, easy to operate, can simplify small drill drift creepage test unit on the whole, saveall cost.Structure of the present invention is simple, easy to use, is easy to manufacture processing, can improve the utilization ratio of blanket gas in small drill drift creepage process of the test simultaneously.

Fig. 2 is the structural representation of bottom seal device;
Fig. 3 is the upward view of Fig. 2;
Fig. 4 is using state schematic diagram of the present invention.
Embodiment
As shown in Figure 1, 2, 3, the present invention includes main snorkel 1, draft tube 2 and bottom seal device 3, the left end of draft tube 2 is connected laterally at the position of the lower middle of main snorkel 1 and is communicated with main snorkel 1, the end, upper end of main snorkel 1 is provided with the first external thread 4, and the lower end of main snorkel 1 is provided with internal thread 6; The middle part of bottom seal device 3 is vertically provided with the preformed hole 5 suitable with the diameter of parts to be measured, preformed hole 5 is through hole, the outside of the first half of bottom seal device 3 is provided with the second external thread 3-1 with lower end internal thread 6 adaptation of main snorkel 1, the latter half of bottom seal device 3 is columniform cylinder table 3-2, the external diameter of cylinder table 3-2 is greater than the diameter of preformed hole 5, so just can play the effect of sealing, common way is the external diameter that the external diameter of cylinder table 3-2 equals main snorkel 1.
The bottom of bottom seal device 3 is provided with flat recess 7, and straight screwdriver easy to use screws.
Draft tube 2 and main snorkel 1 one are connected and vertical.Main snorkel 1, draft tube 2 and bottom seal device 3 all adopt stainless steel to make.
experimentation:
As shown in Figure 4, be inserted in the preformed hole 5 of bottom seal device 3 by the corundum rod 8 of test, the first external thread 4 of main snorkel 1 upper end is threaded with the lower clamp of creep test, and draft tube 2 is connected with blanket gas pipeline.Bottom seal device 3 is threaded with main snorkel 1, displacement measurement parts (corundum rod 8) are directly contacted with the tested sample center on top by the center pit of bottom seal device 3, the lower end of corundum rod 8 directly contacts with displacement transducer, realizes the object directly measuring sample center deformation.Then draft tube 2 passes into blanket gas, thus reaches the object directly measuring sample deformation while passing into blanket gas.
The present invention is used for the air-breather of small drill drift creepage test, and structure is simple, and easy to use, operation controllability is good, is easy to manufacture processing, can simplifies small drill drift creepage device, improve the utilization ratio of blanket gas, save experimentation cost.
Be only a specific embodiment of the present invention above, but the present invention is not limited thereto, the changes that any person skilled in the art can think of, as long as be no more than scope described in appended claims, all should drops in protection scope of the present invention.
