The ball indentation hardness tester provided by the utility model is capable of realizing the full-automatic control on loading, load-holding, indentation depth and hardness value calculation, so that the detection precision is greatly increased.
Description
Technical field
The utility model relates to a kind of sclerometer, is specifically related to a kind of ball indentation hardness meter, belongs to hardness checkout equipment technical field.
Background technology
The sclerometer checkout equipment of prior art adopts mechanical lever counterweight device that plastic samples is applied trial load mostly, utilizes hundred parts of tables to measure the indentor compression distance again, and the sustained load timing mode adopts Stroke Control, thereby detects the hardness of test specimen.
Not enough below above-mentioned sclerometer detection technique exists: as during with mechanical lever counterweight device load test, inertia load can to occur and act on test specimen, reduce the trial load precision.The monitoring in real time of lotus time shortage is measured and held to compression distance, is difficult to accurate control, and test findings is easy to generate than mistake.
Therefore, for solving the problems of the technologies described above, necessary a kind of structure improved ball indentation hardness meter that has is provided, to overcome said defective of the prior art.
The utility model content
For addressing the above problem, the purpose of the utility model is to provide a kind of automaticity height and the high ball indentation hardness meter of accuracy of detection.
For realizing above-mentioned purpose, the technical scheme that the utility model is taked is: a kind of ball indentation hardness meter, and it comprises frame, servomotor, main shaft, elevating lever, indentor, testing table and load sensor; Wherein, said servomotor is installed on the top of frame; Said main shaft vertically is provided with, and its top is connected with servomotor through a shaft coupling; Said elevating lever is screwed together on the main shaft, and its bottom is equipped with said indentor; Said testing table is installed on the frame, its be positioned at indentor under; Said load sensor is positioned at the bottom of testing table.
The ball indentation hardness meter of the utility model further is set to: the side in said indentor further is provided with a displacement transducer, and this displacement transducer is immobilizated on the main shaft.
The ball indentation hardness meter of the utility model further is set to: on said elevating lever, be arranged with a fixed cover, this fixed cover is fixed on the frame.
The ball indentation hardness meter of the utility model also is set to: a side of said frame is provided with a display screen.
Compared with prior art, the utlity model has following beneficial effect: lotus, compression distance, hardness number calculating Automatic Control can be realized loading, held to the ball indentation hardness meter of the utility model, thereby improved accuracy of detection greatly.
Description of drawings
Fig. 1 is the structural representation of the ball indentation hardness meter of the utility model.
Embodiment
See also shown in the Figure of description 1, the utility model is a kind of ball indentation hardness meter, and it is made up of several parts such as frame 1, servomotor 2, main shaft 3, elevating lever 4, indentor 5, testing table 6 and load sensors 7.
Wherein, said frame 1 is with the integrated poured formation of high-strength cast steel spare.One side of said frame 1 is provided with a display screen 10, thereby can realize man-machine conversation.
Said servomotor 2 is installed on the top of frame 1.Said main shaft 3 is vertical setting, and its top is connected with servomotor 2 through a shaft coupling 8.This servomotor 2 rotates through shaft coupling 8 driving main shaft 3.
Said elevating lever 4 is screwed together on the main shaft 3, is just changeing or reverses and realize the oscilaltion of elevating lever 4 through main shaft 3.In these elevating lever 4 bottoms said indentor 5 is installed.On said elevating lever 4, be arranged with a fixed cover 41, this fixed cover 41 is fixed on the frame 1, and it is used to guide elevating lever 4 motions.
Said testing table 6 is installed on the frame 1, its be positioned at indentor 5 under.Said load sensor is positioned at the bottom of testing table.
Further, be provided with a displacement transducer 9 in a side of said indentor 5, this displacement transducer 9 is immobilizated on the main shaft 1.
The principle of work of the ball indentation hardness meter of the utility model is following: utilize servomotor 2 driving main shaft 3, when main shaft 3 rotations, realize the rising or the decline of elevating lever 4; The indentor 5 of different-diameter can be loaded and unloaded in elevating lever 4 bottoms, and when elevating lever 4 descended, the test specimen that can be opposite to testing table 6 applied trial load, controls the trial load that test specimens bear through load sensor 7 sensitivities that are installed on testing table 6 bottoms; Simultaneously, the displacement transducer of installing on the elevating lever 49 can sensitive measure regulation hold lotus after the time indentor be pressed into the degree of depth of test specimen, thereby obtain to be pressed into the surface area of test specimen.Simultaneously, can be at the built-in high accurate calculagraph of this ball indentation hardness meter (not shown), thus come accurate recording to load, hold the lotus time, and go out the ball indentation hardness value of test specimen by special use test computed in software.
Above embodiment is merely the preferred embodiment of this creation, not in order to limiting this creation, any modification of being made within all spirit and principles in this creation, is equal to replacement, improvement etc., all should be included within the protection domain of this creation.
