Abstract
The invention discloses a detection device and a detection method for an elastic characteristic value of a small-scale dish-shaped gasket. The detection device is provided with a support fixed on a lower plate of a tension-compression test machine, wherein the support extends to the upper part of an upper pressing plate of the tension-compression test machine, with a bent portion, and the bent portion is provided with a dial gauge head testing the down-pressing size of the upper pressing plate of the tension-compression test machine; and a pedestal is placed on the lower plate of the tension-compression test machine, and a deformation standard block detecting a deflection amount of the tension-compression test machine is placed on the pedestal. When the elastic characteristic value of a small-scale dish-shaped gasket type part with a smaller deflection amount is measured, the detection device of the invention is disposed on the tension-compression test machine, and therefore the disadvantages that the self rigidity of the tension-compression test machine changes and the deflection amount cannot be measured accurately can be overcomed, the measuring accuracy and the repeated measuring precision of the elastic characteristic value of the dish-shaped gasket type part are assured, and the provided data is guaranteed to be accurate.
Description
Technical field
The invention belongs to elastic force testing tool technical field, be specifically related to a kind of small size saucer washer characteristic elastic force value detection device and detection method thereof.
Background technology
In product design, often run into the typical part butterfly gasket, need be given in characteristic elastic force value under the certain deformation in some important use occasions, because there is not the special measurement instrument, the measurement of characteristic elastic force value generally is to carry out at spring tension and compression testing machine (hereinafter to be referred as testing machine).But concrete the measurement finds in the practice that the accurate characteristic elastic force value of measuring under certain distortion has following deficiency on testing machine: a) testing machine self insufficient rigidity produces the elastic force value variation that small deformation brings; B) be difficult for the accurate distortion value of determining part at testing machine.Just because of above 2 existence, cause the characteristic elastic force value difficulty of accurate measurement butterfly gasket, particularly the butterfly gasket characteristic elastic force value accuracy of small size, small deformation and repeatability can not get guaranteeing, make to obtain accurate characteristic elastic force Value Data in production practices.
Summary of the invention
Overcome existing deficiency, the object of the present invention is to provide a kind of precision height, can accurately measure the small size saucer washer characteristic elastic force value detection device of butterfly gasket characteristic elastic force value.
Another object of the present invention is to provide a kind of detection method of small size saucer washer characteristic elastic force value detection device.
For achieving the above object, the technical solution used in the present invention is: this small size saucer washer characteristic elastic force value detection device, has the support that is fixed on the tensile and compression testing machine lower shoe, it is characterized in that: the top that described support extends to the tensile and compression testing machine top board has bending part, described bending part fixedly has the clock gauge head, described clock gauge head is used for measuring the size that the tensile and compression testing machine top board presses down, be placed with base on the described tensile and compression testing machine lower shoe, be placed with the distortion calibrated bolck for detection of the tensile and compression testing machine deflection on the base.
A kind of small size saucer washer characteristic elastic force value detection method is characterized in that by following step operation:
1, the support with pick-up unit of the present invention is fixed on the tensile and compression testing machine lower shoe;
2, the clock gauge head is fixed to the bending part on support top, uses the clock gauge head accurately to indicate the distortion value;
3, will be out of shape calibrated bolck and be put on the cushion block that is positioned on the tensile and compression testing machine lower shoe, for reducing error, the distortion calibrated bolck will be put under the clock gauge head contact, and part also will be put under the clock gauge head contact when in like manner measuring;
4, the top board of tensile and compression testing machine is pressed onto above the distortion calibrated bolck, and continues to pressing down, be docked to the nominal value of characteristic elastic force value up to the indicating value dial plate of tensile and compression testing machine, this moment is with the zero clearing of clock gauge head;
5, decontrol the top board of tensile and compression testing machine, take out the distortion calibrated bolck, put into tested part then, the top board of tensile and compression testing machine is pressed onto on the part, to null value, the indicating value of reading tensile and compression testing machine is exactly in the characteristic elastic force value of specifying under the distortion size up to the clock gauge head.
Adopt the beneficial effect of technique scheme: this small size saucer washer characteristic elastic force value detection device is the accessory that is fitted on the testing machine, this device is provided with the clock gauge head, the clock gauge head is fixed on the support and contact and tensile and compression testing machine top board surface are contacted, the accurately variation of indication elastic washer deflection, and the elastic force value that when the corresponding deformation amount, is obtained elastic washer by the tension and compression machine, can directly read elastic force value, intuitive and convenient from tensile and compression testing machine.This device also has the distortion calibrated bolck, and the distortion calibrated bolck is demarcated the deflection zero-bit point that packing ring is set, and revises the error that the equipment rigid deformation of tension and compression machine in detecting elastic force value scope brought simultaneously, guarantees to detect the repeatable accuracy of data.Compared with prior art, deformation values can accurately be measured and indicate to this pick-up unit, effectively overcome simultaneously the variation that lower platen brings the elastic force value because of the not enough generation distortion of rigidity on the tensile and compression testing machine in pressurized process, guaranteed accuracy and stability that characteristic elastic force value is measured.Through practice, effect is better, plays a good role to guaranteeing product quality.This detection method is simple, and is easy to operate, adapts to the detection of various small size saucer washer characteristic elastic force values.
