Abstract

The utility model relates to a low-hardness object thickness measuring tool, comprising a measuring table, a base, and a thickness measuring instrument. An upper surface of the measuring table is provided with the base and a reference probe. Slide rails are vertically disposed on an upper surface of the base. The thickness measuring instrument is disposed on the slide rails in a matched manner. When the measuring tool measures a low-hardness object, a chunking force range is set according to hardness of a to-be-measured object, thereby preventing the low-hardness object from being measured after deformation when being clamped, and reducing influence of deformation when the low-hardness object is clamped on measuring results.

Description

Soft object thickness survey instrument

Technical field

The utility model relates to tool for measuring thickness, relates in particular to soft object thickness survey instrument.

Background technology

Thickness measure can be divided into according to metering system: the direct method of measurement, the indirect method of measurement; Commonly used in the indirect method of measurement have a ultrasonic Method for Measuring, and ultrasound wave is to utilize the propagation of sound in material and the thickness of the time Calculating material that reflects, and this measuring method is not suitable for the thickness measure of the object of multiple material hierarchal arrangement.

Thickness measure generally is divided into two kinds according to the way of contact: a kind ofly be contact thickness measurement equipment, a kind of for the non-contact thickness measuring instrument; Mainly there is inaccurate problem when measuring for the large article of surface roughness for the non-contact thickness measuring instrument, and has the comparatively complicated problem of instrument and equipment.

Generally, if the contact thickness measurement equipment needs clamping all can cause being held the deformation at position when detect thickness, the larger this deformation of hardness is just less, otherwise the less this deformation of hardness is just larger; When if we need to carry out clamping when the object to softness carries out thickness measure, we divide many people to measure will find that everyone measurement result is different, and this is because everyone is different to the judgement of clamping situation; Same people also might be different in the result of different time measurements.

Present contact type measurement instrument is mainly used in the thickness measure to the rigidity regular object, survey instrument for the irregular object of flexibility is less, the problems such as mostly there is complex operation step in existing survey instrument to the irregular object of soft, and measurement accuracy is not high, and human factor is more.

All wish in the situation that do not destroy product the thickness of product is measured for a lot of industries, but because material own is softer, can't carry out with normal measuring method the surveying work of thickness, can only adopt the method that rear use dip stick is directly measured is cut off at position to be measured.

Described demonstration and control device comprise that casing, display, parameter arrange button, pressure indicator light, measurement control knob and motor; Described display, parameter arrange button, pressure indicator light and measurement control knob and are embedded at respectively on the front surface of casing, and described motor comprises main CD-ROM drive motor and step motor, and this main CD-ROM drive motor and step motor are installed on the rear surface of casing; Display is used for showing the parameters value; Parameter arranges button and is used for running speed to motor, the movement velocity of thickness measurement equipment and return height, and low pressure limit and the higher limit of pressure sensitive probe and pressure indicator light arrange; Pressure indicator light is used for respectively showing that pressure transducer touches with suitable pressure and object being measured or shows that pressure transducer touches with excessive pressure and object being measured; The measurement control knob is used for controlling motor the operation of thickness measurement equipment is controlled; Main CD-ROM drive motor and step motor are used for respectively driving thickness measurement equipment and move up and down fast or move up and down in a stepwise manner.

Principle of work

Referring to Fig. 5～shown in Figure 6, step is:

First step setup parameter: at first, object being measured according to different materials and different hardness calculates suitable force value, show and control device 31 on upper pressure limit value and low pressure limit value when button 314 being set being arranged on pressure sensitive probe 34 and using by parameter; Then the travelling speed of thickness measurement equipment 3 is adjusted; At last thickness measurement equipment 3 is adjusted to a suitable height, to be convenient for measuring;

Second step zero clearing: click the measurement control knob 316 on demonstration and the control device 31, pressure sensitive 34 descending and the benchmark probe 11 of popping one's head in is touched, then, stop the descending of pressure sensitive probe 34, the one-tenth-value thickness 1/10 that shows on demonstration and control device 31 display screens 313 is carried out zero clearing, click again the measurement control knob 316 on demonstration and the control device 31, make pressure sensitive 34 up and the benchmark probe 11 of popping one's head in separate an end distance, so that the accommodating object being measured of energy between pressure sensitive probe and the benchmark probe;

The 3rd pacing amount testee thickness: at first, object being measured is positioned on the benchmark probe 11, then, click and measure control knob 316, pressure sensitive is popped one's head in 34 descending, when pressure sensitive probe 34 with after object being measured contacts, unclamp measurement control knob 316; At this moment, referring to shown in Figure 5, as show and control device 31 on pressure indicator light 315 be shown as green light, illustrate that pressure sensitive probe 34 touches with correct pressure and measured object surface, then direct display 313 at demonstration and control device 31 reads corresponding one-tenth-value thickness 1/10; Referring to shown in Figure 6, if pressure indicator light 315 is shown as red light, illustrate that pressure sensitive probe 34 touches with excessive pressure and measured object surface, and make the measured object surface recessed, then also need click and measure control knob 316, Driving Stepping Motor makes thickness measurement equipment 3 steppings up, until pressure indicator light 315 is shown as green light, then read the correct one-tenth-value thickness 1/10 of object being measured.

The utility model is set the holding force scope according to the hardness of object under test when the soft object is measured so that the soft object when being held, avoid occurring being out of shape after measured situation, reduced since the distortion during clamping on the impact of measurement result.
