Abstract
The utility model relates to a ceramic three-point bending test fixture for a high-temperature vacuum chamber, which comprises two parallel supporting rollers (5) and connecting plates (8) positioned at the two ends of the supporting rollers; the two connecting plates (8) opposite to the two ends of each supporting roller (5) are connected with each other through pins (7) and are fixedly arranged on a base (3) through the pins (7), the base (3) is positioned below the supporting rollers (5), two side plates (2) are mounted on the two sides of the base (3), a bolt (1) penetrates through the base (3) and the two side plates (2) to be locked and fixed by a nut (9), and a ceramic specimen (6) is placed on the parallel supporting rollers (5). The ceramic three-point bending test fixture is characterized in that two pairs of carbon felts (4) for clamping the ends of the ceramic specimen (6) are correspondingly arranged at the two ends of the ceramic specimen (6). The ceramic three-point bending test fixture has the advantages that the ceramic specimen (6) can be stabilized on the supporting rollers during the vacuum-pumping and the heating processes, and the experimental result accuracy and the experimental efficiency are improved.
Description
Technical field
The utility model relates to a kind of ceramic bending strength test device, is specifically related to a kind of ceramic three point bending test fixture for high-temperature vacuum chamber.
Background technology
Conventionally, the fixture of ceramic three point bending test comprises depression bar and the bearing with pressure head, and depression bar is afterburning member, the integrated component that bearing is made up of base, a roller, web joint etc., and on bearing, two symmetrical rollers are supporting ceramic test piece.
In process of the test, the level that ceramic test piece need be positioned over is propped up middle, the top place of roller, and makes ceramic test piece vertical with a roller in the horizontal direction, and keeps vertical at vertical direction and depression bar pressure head, but conventional ceramic test fixture all lacks corresponding centering instrument.And for the ceramic bending test of high-temperature vacuum chamber, vacuumizing and heating process testing machine can be shaken, the ceramic test piece originally having placed is slided, even dropping, thereby cause test findings inaccurate or failed, therefore test efficiency is lower.
Utility model content
The shortcoming existing in order to overcome prior art, technical problem to be solved in the utility model is just to provide a kind of ceramic three point bending test fixture for high-temperature vacuum chamber, it can avoid vacuumizing with heating process in ceramic test piece slide, improve accuracy and the conventional efficient of test findings.
Technical problem to be solved in the utility model is to realize by such technical scheme, it comprises two parallel rollers and is positioned at the web joint at a roller two ends, each root props up two relative web joint pins of roller two ends and connects, and by pin, web joint is fixed on base, base is positioned at the below of a roller, two blocks of side plates are equipped with in base both sides, bolt is fixed with nut lock through base and biside plate, ceramic test piece is placed on two parallel propping up on roller, and the two ends correspondence of ceramic test piece is provided with the carbon felts of two pairs of clamping ceramic test piece terminations.
Owing to carbon felt, ceramic test piece being clamped in to the centre of a roller, in experimentation, carbon felt can not impose on the power that ceramic test piece is too large, but have enough try hard to keep card ceramic test piece vacuumize and heating process in be unlikely to slide, keep the initial verticality of ceramic test piece and pressure head, thereby improve experimental result accuracy and conventional efficient.So the utlity model has following advantage: vacuumize and heating process in can make ceramic test piece stable on roller, improved experimental result accuracy and conventional efficient.
Brief description of the drawings
Brief description of the drawings of the present utility model is as follows:
Fig. 1 is front view of the present utility model;
Fig. 2 is vertical view of the present utility model.
In figure: 1. bolt; 2. side plate; 3. base; 4. carbon felt; 5. a roller; 6. ceramic test piece; 7. pin; 8. web joint; 9. nut.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail:
As depicted in figs. 1 and 2, the utility model comprises two parallel rollers 5 and is positioned at the web joint 8 at a roller two ends, each root props up relative two web joints, the 8 use pins 7 of roller 5 two ends and connects, and by pin 7, web joint 8 is fixed on base 3, base 3 is positioned at the below of a roller 5, two blocks of side plates 2 are equipped with in base 3 both sides, bolt 1 is locked through base 3 and biside plate 2 use nuts 9, ceramic test piece 6 is placed on two parallel propping up on roller 5, and the two ends correspondence of ceramic test piece 6 is provided with the carbon felts 4 of two pairs of clamping ceramic test piece 6 terminations.
Carbon felt 4 of the present utility model can adopt different in width for the size of different ceramic test pieces 6.
