Abstract
The utility model discloses a device for detecting a characteristic elasticity value of a small-size disc gasket. The detection device comprises a bracket fixed on a lower bottom plate of a tensile and compression testing machine, wherein the bracket extends to the upper part of an upper pressing plate of the tensile and compression testing machine to form a bending part; a dial indicator head is fixed on the bending part; the dial indicator head is used for measuring the size of the downwards pressed upper pressing plate of the tensile and compression testing machine; a pedestal is arranged on the lower bottom plate of the tensile and compression testing machine; and a deformation standard block used for detecting deformation of the tensile and compression testing machine is arranged on the pedestal. When the characteristic elasticity value of a part such as a small-size small-deformation disc gasket is measured, the detection device is assembled on the tensile and compression testing machine, the defects that the tensile and compression testing machine has stiffness change and the deformation value cannot be accurately determined can be overcome, the accuracy and repeated measurement precision of the measured characteristic elasticity value of the part such as the disc gasket are ensured, and accurate data is provided.
Description
Technical field
The utility model belongs to elastic force testing tool technical field, is specifically related to a kind of small size saucer washer characteristic elastic force value detection device.
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 purpose of this utility model 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.
For achieving the above object, the technical solution adopted in the utility model 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.
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.
Description of drawings
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
