Description
Technical field
The utility model is measured technical field of measurement and test, particularly a kind of pallet deformation quantity measurement mechanism of compression testing machine.
Background technology
For pallet deformation quantity, measure the main contact micro-displacement sensor that adopts at present, type has resistance-type, condenser type and grating etc.According to the relative displacement of measurement point, measure the pallet deformation quantity under regulation bending strength.Also have more traditional directly measuring with ruler exactly.
Use the drawback of contact micro-displacement sensor to be: 1, must contact with measurement face, easily affect measurement result; 2, the long-time physical construction of can wearing and tearing of using, causes displacement measurement inaccurate; 3, contact micro-displacement sensor structure is long, and testee below limited space, is difficult for placing.The drawback of using ruler directly to measure is: measure efficiency not high, measuring error is larger, for a long time test constantly.
Utility model content
The utility model, for prior art above shortcomings, provides a kind of pallet deformation quantity measurement mechanism of compression testing machine.The utility model is achieved through the following technical solutions:
A pallet deformation quantity measurement mechanism for compression testing machine, in order to measure the deformation quantity of the measurement face of a pallet, comprising:
At least one ultrasonic sensor, in order to measure the change of distance amount between measurement face and ultrasonic sensor, and exports corresponding electric signal;
Governor circuit, comprise: analog-to-digital conversion module and communication protocol module, analog-to-digital conversion module connects at least one ultrasonic sensor, in order to carry out analog to digital conversion according to electric signal, obtain the deformation quantity of the face of measuring, communication protocol module connects host computer, in order to deformation quantity is sent to host computer according to preset protocol.
Preferably, at least one ultrasonic sensor is arranged at respectively the below of the required measurement point of measurement face, under the state of measurement face being exerted pressure at a compression testing machine, at least one ultrasonic sensor detects the change of distance amount between measurement face and ultrasonic sensor that obtains.
Preferably, the quantity of ultrasonic sensor is four.
The utility model is measured the deformation quantity of pallet by ultrasonic sensor, and data are changed in real time and sent, and can effectively solve the defect of existing pallet deformation quantity measurement mechanism, and has the technique effect that measuring accuracy is high, efficiency is high.
Accompanying drawing explanation
Shown in Fig. 1 is structural representation of the present utility model;
Shown in Fig. 2 is workflow diagram of the present utility model.
Embodiment
Below with reference to accompanying drawing of the present utility model; technical scheme in the utility model embodiment is carried out to clear, complete description and discussion; obviously; as described herein is only a part of example of the present utility model; it is not whole examples; embodiment based in the utility model, the every other embodiment that those of ordinary skills obtain under the prerequisite of not making creative work, belongs to protection domain of the present utility model.
For the ease of the understanding to the utility model embodiment, below in conjunction with accompanying drawing, take specific embodiment and be further explained as example, and each embodiment does not form the restriction to the utility model embodiment.
The pallet deformation quantity measurement mechanism of a kind of compression testing machine that as shown in Figure 1, the utility model provides comprises: ultrasonic sensor 1, governor circuit 2, host computer 3.Governor circuit 2 comprises: analog-to-digital conversion module 21 and communication protocol module 22.
Shown in Fig. 2, principle of work of the present utility model is: ultrasonic sensor 1 is arranged at the below of the required measurement point of measurement face, and the change of distance amount of required measurement point is detected, and exports corresponding electric signal.Generally speaking, the electric signal of sensor output is simulating signal, so governor circuit 2 needs first it to be carried out to analog to digital conversion after receiving this simulating signal, after the conversion through analog-to-digital conversion module 21, electric signal is converted to is convenient to the deformation quantity (digital signal) that governor circuit is processed.Then by communication protocol module 22, deformation quantity is read, calibrates, is arranged the operations such as other parameters to host computer 3 according to certain protocol transmission.The function of host computer is identical with existing technology, and the utility model does not repeat at this.
In the present embodiment, the quantity of ultrasonic sensor 1 is 1, yet the quantity of ultrasonic sensor 1 is to determine according to the quantity of required measurement point, can be 4 or more, and the utility model does not limit this.
The utility model is measured the deformation quantity of pallet by ultrasonic sensor, and data are changed in real time and sent, and can effectively solve the defect of existing pallet deformation quantity measurement mechanism, and has the technique effect that measuring accuracy is high, efficiency is high.
The above; it is only preferably embodiment of the utility model; but protection domain of the present utility model is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claim.
