The utility model relates to a belt tensile force tester, which includes a shell and a test circuit arranged inside the shell. The test circuit includes a SCM, an amplifying and rectifying circuit, a comparator and a LCD. A strain sensor is connected with the amplifying and rectifying circuit inside the shell through data lines, the amplifying and rectifying circuit is connected with the comparator, the comparator is connected with the input end of the MCU, and the output end of the MCU is connected with the LCD. Voltage signals generated from the strain sensor are amplified, rectified, compared, computed by the MCU, and displayed as data on the LCD. The utility model is power supplied by a dry battery, and is used to measure tensile force of the belt at a high precision. The utility model is characterized in small volume and light weight, and applies to assembling personnel at the production line. The utility model can directly display the tensile force value of the motor transmission belt without unit conversion. The utility model is a portable meter to test tensile force of the belt during assembling of automobile motors or diesel motors.
Description
Technical field
The utility model belongs to the detecting instrument field, relates to a kind of belt tension tester, the process that is used for assembling motor car engine, diesel motor, the tension value of detection belt.
Background technology
China has become the big automobile consumption market, third place in the world and the world the fourth-largest automobile production state at present.Along with continuous growth to the automobile demand amount, more and more higher, more and more thinner to the auto-producing requirement, also more and more higher to the requirement of driving belt tensile force.The belt tension tester is the process that is used for assembling motor car engine, diesel motor, in order to regulate the size of belt tension, makes in engine operation process, to obtain optimum transfer efficient, and the detection of the belt tension value that need carry out.Belt tension is too small, and transmission efficiency is low, belt slip, and belt tension is excessive, and serious wear influences belt life.Therefore, in the engine assembling process, belt tension should be adjusted to certain power value scope, guarantee the performance of engine.Existing belt tension detector is a vibration frequency of measuring belt, converses the SEEM value of belt with the vibration frequency of belt, operates more complicated, calculates cumbersome.
Summary of the invention
Problem to be solved in the utility model is, overcomes the deficiencies in the prior art, and a kind of belt tension tester is provided, and can directly show the tension value of engine driving belt, and does not need to carry out unit conversion.
The utility model solves its technical matters and takes following technical scheme to realize:
A kind of belt tension tester that provides according to the utility model, comprise housing and be contained in the interior test circuit of housing, test circuit comprises single-chip microcomputer, amplification and rectification circuit, comparer and LCD, strain transducer is connected with amplification and rectification circuit in the housing through data line, amplification and rectification circuit connects comparer, and comparer connects the input end of single-chip microcomputer; The output terminal of single-chip microcomputer connects LCD; The voltage signal that strain transducer produces is through amplifying shaping relatively, by the single-chip microcomputer analytical calculation, by the LCDs video data.
It is to take following technical scheme further to realize that the utility model solves its technical matters:
Aforesaid strain transducer is contained on the anchor clamps, is shaped on a knob that screws anchor clamps on the anchor clamps;
Be shaped on a power switch on the aforesaid housing.
The utility model compared with prior art has significant advantage and beneficial effect.
The utility model adopts dry cell power supply, is used for the tension value of high-acruracy survey belt, light weight, and the portable type measuring instrument, volume is little, in light weight, is fit to the production line assembly crewman and uses.What this instrument adopted is the SEEM value that directly can directly measure belt with the clamp belt, simple to operate, accurately, directly shows the SEEM value of engine driving belt, does not need to carry out the conversion of unit, can directly use east wind sign vehicle.
