Abstract
The utility model discloses a friction coefficient test desk. The friction coefficient test desk comprises a base (1), a support frame (2), a lower fixed support plate (3), a guide rail (4) and an upper fixed support plate (5), wherein the guide rail (4) is longitudinally parallelly arranged on the lower fixed support plate (3); the upper end of the guide rail (4) is connected with the upper fixed support plate (5); a jack (7), a pressure sensor (8), an upper jig (9) and a lower jig (10) are sequentially arranged between the upper fixed support plate (5) and the lower fixed support plate (3) from top to bottom; both sides of the upper jig (9) are provided with tension sensors (11) tangentially restraining the upper jig (9); the lower jig (10) is driven by a servo motor (6) to rotate; and a heating ring (12) is sleeved on the lower part of the upper jig (9). The friction coefficient test desk provided with a local heating device only heats aiming at a friction test piece body, thereby reducing the integral cost and greatly saving the energy resources during a test.
Description
Technical field
The utility model relates to the material tests field, relates in particular to a kind of test board that detects friction factor.
Background technology
In order to obtain the friction factor between the friction material, need build the friction factor test board.Existing friction factor test board need be put test board integral body in the temperature control box into when carrying out hot test, makes the whole cost of test board increase.For this reason, patent of the present invention has designed a friction factor test board with area heating installation, only heats to friction test specimen itself, has reduced overall cost.
The utility model content
The utility model technical matters to be solved be to provide a kind of self can be to the friction factor test board of material heating to be detected.
The technical scheme of the utility model is following: a kind of friction factor test board; Comprise pedestal (1), bracing frame (2), decide back up pad (3), guide rail (4) and last down and decide back up pad (5); Wherein said guide rail (4) parallel longitudinal is arranged on down to be decided on the back up pad (3); Said two guide rails (4) upper end connects to go up decides back up pad (5); Decide back up pad (5) on said and decide to be disposed with from top to bottom between the back up pad (3) lifting jack (7), pressure transducer (8), last anchor clamps (9) and lower clamp (10) down; Said anchor clamps (9) both sides of going up are provided with pulling force sensor (11) to its tangential constraint, and said lower clamp (10) is by servomotor (6) driven rotary, and its key is: said anchor clamps (9) bottom of going up is with heating collar (12).When detecting, the material to be detected between last anchor clamps (9) and lower clamp (10) is positioned at heating collar (12).Only the material that detects is heated, need not put entire equipment in the temperature control box into, needn't use resistant to elevated temperatures material entirely for the friction factor test board, reduced whole cost, spot heating has also been practiced thrift electric energy when detecting simultaneously.
As optimization, above-mentioned upward anchor clamps (9) upper diameter is big, and lower diameter is little, and said heating collar (12) cooperates with last anchor clamps (9) lower thread.
Beneficial effect: the utlity model has the friction factor test board of area heating installation, only heat, reduced overall cost, also practiced thrift the energy during test greatly to friction test specimen itself.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further:
As shown in Figure 1; A kind of friction factor test board; Mainly by pedestal 1, bracing frame 2, decide back up pad 3, guide rail 4 and go up and decide back up pad 5 and forms down, wherein said guide rail 4 parallel longitudinals are arranged on down to be decided on the back up pad 3, and the connection of said two guide rails 4 upper ends is last decides back up pad 5; Decide back up pad 5 on said and decide to be disposed with from top to bottom between the back up pad 3 lifting jack 7, pressure transducer 8, last anchor clamps 9 and lower clamp 10 down; Said anchor clamps 9 both sides of going up are provided with pulling force sensor 11 to its tangential constraint, and said lifting jack 7 upper ends are fixed on decides back up pad 5, and these lifting jack 7 lower ends are fixed with moving back up pad 13.Moving back up pad 13 can be slided on guide rail 4.Should connect pressure transducer 8 in moving back up pad 13 belows, these pressure transducer 8 lower ends connect pressure transducer pedestal 14.Pressure transducer pedestal 14 belows are last anchor clamps 9, are pressed with adjustment ball 15 between pressure transducer pedestal 14 and the lower clamp 9.Last anchor clamps 9 are corresponding with lower clamp 10, and said lower clamp 10 is specially servomotor 6 and is driven speed reduction unit 16 by servomotor 6 driven rotary, drives lower clamp 10 rotations by speed reduction unit 16.Said anchor clamps 9 bottoms of going up are with heating collar 12.Said upward anchor clamps 9 upper diameter are big, and lower diameter is little, and said heating collar 12 cooperates with last anchor clamps 9 lower thread.
Although more than combine accompanying drawing that the preferred embodiment of the utility model is described; But the utility model is not limited to above-mentioned embodiment; Above-mentioned embodiment only is schematic rather than determinate, and those of ordinary skill in the art is under the enlightenment of the utility model, under the prerequisite of the utility model aim and claim; Can make multiple similar expression, such conversion all falls within the protection domain of the utility model.
Claims (2)
