Description
Technical field
Loading method is tested the present invention relates to a kind of four stations strain gauge load cell creep, including it is same using four stations
The step of Shi Jinhang loadings are tested and conveyed using the two-way automatic cycle of strain gauge load cell.
Add the invention further relates to a kind of four stations strain gauge load cell creep loading device for testing, including four synchronizations
The loading chain of load, the loading bench moved back and forth back and forth with horizontal and vertical guide rail belongs to the innovation in creep test device field.
Background technology
Strain gauge load cell, is mainly used in engineering dynamometry and Weighing.Strain gauge load cell is that manufacture is each
The main devices of electronic scale are planted, the precision height of the sensor directly affects the quality of electronic scale.In strain gauge load cell
Performance parameter in, the croop property parameter of strain gauge load cell directly influences the finger such as measurement accuracy, measurement accuracy
Mark.Therefore, the detection of weighing sensor croop property has very important meaning to weighing sensor.In actual production, claim
Retransmitting the detection of the croop property of sensor also includes instantaneous back to zero, and this two indexs can be completed in a creep test process.
In the test of traditional strain gauge load cell croop property, mainly using two schemes：Firstth, for amount
The miniature weighing sensor used on journey aluminium alloy weighing sensor less than normal and human body balance, is combined many using portable counterweight mostly
The system of passage acquisition instrument composition, and hand-kept data complete creep and the test of instantaneous back to zero；The technical scheme is present
The shortcomings of big workman's amount of labour, low production efficiency, the slow picking rate of data.Second, for the larger stainless steel of range and
Steel alloy weighing sensor, mostly using comparison-type, lever, superposing type force measuring machine combination single channel acquisition instrument, computer
Complete creep and the test of instantaneous back to zero.A weighing sensor, and weighing and sensing can only be disposably loaded in the technical scheme
Can not realizing for device is automatically entered and exported, and the staff of configuration is more, low production efficiency.
In order to overcome the defect of existing strain gauge load cell creep test, there has been proposed design weighing sensor
The system that creep is loaded and tested automatically, to improve production efficiency, meanwhile, increase the accuracy of test.Such as in Chinese patent Shen
Please number be 201110443493.2 in disclose a kind of multi-head electronic formula high-temerature creep permanent strength testing machine, this technical scheme
The stretching attachment means that frame is used to constrain sample provided with two or more, each stretching attachment means of the testing machine are only
Vertical control, lasting or creep test can be carried out respectively.Though this technical scheme can realize that multiple creep tests are carried out simultaneously, work as
When the quantity of stretching attachment means is more, it is necessary to which many people complete to test to coordinate, and increase personnel, efficiency are reduced, so technology
Scheme has technological deficiency.The technical scheme of the bull creep testing experiment machine provided beyond above-mentioned patent, is seldom related to
Using the technical scheme of multistation creep loading test device.
The invention discloses a kind of four stations strain gauge load cell creep test loading method and device, four stations
Loaded and tested simultaneously, the testing efficiency of strain gauge load cell can be effectively improved, meanwhile, loaded using horizontal, longitudinal direction
Device is realized to the conveying of the two-way automatic cycle of strain gauge load cell.
The content of the invention
