Abstract
The utility model relates to a clamping type belt tension detector, comprising a special fixture, a connecting line and an instrument end, wherein the special fixture comprises an upper fixture, a lower fixture, a strain sensor, a support frame and a spring; the instrument end comprises a power supply conversion circuit, an operational amplifying circuit, an undervoltage warming circuit, a singlechip circuit and a liquid crystal display circuit; and the special fixture is used for fixing a belt required to be tested, fixed pressure is applied to the tested belt by virtue of a torque knob, tension size of the belt is displayed from the instrument end, and tension when the belt is in a static state is measured by measuring deformation of the belt in a length direction.
Description
Technical field
The utility model belongs to the automotive fittings detection range, relates to a kind of clipping belt tension detector, measures the tension force of belt when the stationary state through measuring distortion that belt produces length direction.
Background technology
Belt gear because his distinctive superiority Industrial Application is more and more widely in modern times.Also be absolutely necessary one in the automotive field belt gear.The loose tension of the mistake of belt all can influence wearing and tearing belt and belt shaft and serviceable life.Cross pine and can cause and skid, excessive belt stretch can influence wearing and tearing and abnormal sound of belt etc.Past, traditional method of leaning on experience to judge did not re-use in the industry in modern times yet.Must need accurately to measure the tension value of belt.China mainly contains two kinds of methods at present, and a kind of is supercritical ultrasonics technology, and a kind of is displacement method.And the shortcoming of ultrasound wave tensiometer is that accuracy receives quality, the physical dimension of belt, the error of train, the ground unrest of belt, and air-flow (wind) scratches that to influence fluctuation range bigger.Displacement method: principle is under the belt of tensioning, and belt is applied certain known pulling force, measures the amount of deflection that under this acting force, produces, and amount of deflection is converted into the belt tension value according to certain corresponding relation.
Summary of the invention
The utility model problem to be solved is; Overcome the deficiency of prior art; A kind of clipping belt tension detector is provided; Unique anchor clamps can be when measuring belt and produce stationary state to belt apply distortion that certain pressure makes belt produce length direction measure belt tension force, be used to measure the belt tension of various engines, the easy clamping that hand can spare the degree of tightness of adjustment belt is the belt tension detector.
The utility model solves its technical matters and takes following technical scheme to realize:
The utility model relates to a kind of clipping belt tension detector, comprises unit clamp, connecting line, instrument end, and described unit clamp comprises anchor clamps, lower clamp, adaptability to changes sensor, bracing frame, spring; The instrument end comprises power-switching circuit, operational amplification circuit, undervoltage warning circuit, single chip circuit, liquid crystal display circuit; Fix the belt that to test with unit clamp, apply fixation pressure to tread belt, show the size of belt tension from the instrument end through torque knob.
After the electric signal that tension force produced that aforesaid adaptability to changes sensor produces the Belt Length distortion relatively amplifies conversion through differential operational amplifier; Demonstrate measurement result through single-chip microcomputer calculating and through liquid crystal display circuit, voltage comparator circuit is used to detect the battery low-voltage warning function.
The utility model compared with prior art has tangible advantage and effect.
The utility model be designed with unique anchor clamps can be when measuring belt and produce stationary state to belt apply distortion that certain pressure makes belt produce length direction measure belt tension force; Be used to measure the belt tension of various engines, the easy clamping that hand can spare the degree of tightness of adjustment belt is the belt tension detector.
The embodiment of the utility model is provided by following embodiment and accompanying drawing in detail.

Embodiment
Below in conjunction with accompanying drawing and embodiment,, concrete embodiment, structure, characteristic and function be elaborated as follows to being provided according to the utility model:
Referring to Fig. 1-2, a kind of clipping belt tension detector
,Comprise unit clamp, connecting line, instrument end, described unit clamp comprises anchor clamps, lower clamp, adaptability to changes sensor, bracing frame, spring; The instrument end comprises power-switching circuit, operational amplification circuit, undervoltage warning circuit, single chip circuit, liquid crystal display circuit; Fix the belt that to test with unit clamp, apply fixation pressure to tread belt, show the size of belt tension from the instrument end through torque knob.
After the electric signal that tension force produced that aforesaid adaptability to changes sensor produces the Belt Length distortion relatively amplifies conversion through differential operational amplifier; Demonstrate measurement result through single-chip microcomputer calculating and through liquid crystal display circuit, voltage comparator circuit is used to detect the battery low-voltage warning function.
After opening power switch device, add the belt that will test with the belt unit clamp, apply fixation pressure through torque knob to belt.The strain pressure transducer is converted into electric signal with belt in the distortion that stationary state produces length direction, and through AD802, chip is sent out big the conversion after the ATMG64 single-chip microcomputer calculates, and shows through display screen at last.The novel transformational relation that has also comprised undervoltage warning prompt facility and SEEM value and newton's value of this use in addition.
Operation instruction:
Instrument uses the 9V powered battery, at first opens the switch above the instrument during with measurement.At first meeting on the inspection apparatus.Meeting shows that " LOW BAT " J point out warning on the low screen if cell voltage is crossed, and please change battery, adds to hold with unit clamp then to fix the belt that will detect, and the adjustment torque knob applies fixation pressure to belt and when hearing to rattle away.Behind three sounds; The size that can show belt tension from the instrument end; Switch through the side can carry out the conversion of SEEM and tension force, if the test value of belt is excessive or too smallly can adjust the degree of tightness that belt pulley is adjusted belt, gets final product up to the scope of meeting the requirements of.
