Description
Technical field
The invention belongs to field of structural design.More particularly to a kind of automatic classification load feedback device.
Background technique
Mechanics device in bearing structure generally require feedback load magnitude, when load range is larger, in order to obtain compared with
High load feedback accuracy, it usually needs using the sensor of different ranges, testing crew is needed to carry out frequently more sensor
It changes, at this point, not only to operate convenience poor for the replacement of load transducer, but also working efficiency is low, and labor intensity is high.
The invention proposes a kind of automatic classification load feedback device, which is not only able to satisfy in same mechanics device
Demand to large span load range, and it is able to carry out automatic classification, operation link is simplified, is improved work efficiency, is dropped
Low labor intensity.
Summary of the invention
The purpose of the present invention is: a kind of automatic classification load feedback device is designed, it is big for load range span and need frequency
The load operations of numerous more emat sensor.
To solve this technical problem, the technical scheme is that
A kind of automatic classification load feedback device includes carrying shell 1, the first load transducer 2, the second load transducer
3, spring 4, upper connecting rod 5 have retention bead 7 on upper connecting rod 5, it is characterised in that pass through spring 4 and change retention bead 7 and carrying shell
The switching of the working condition of the first load transducer 2 and the second load transducer 3 is realized in the relative position of body 1, and then realizes and carry
The automatic classification of lotus feedback.
The spring 4, the first load transducer 2, the retention bead 7 on upper connecting rod 5 are installed in the interior of carrying shell 1
In portion's cavity, the loading end of upper connecting rod 5 is stretched out by the hole on carrying 1 top of shell；One end of first load transducer 2 is mounted on
The lower end of upper connecting rod 5, the other end are connected with one end of spring 4；The other end of spring 4 is installed on the bottom inside carrying shell 1
On the bottom surface at end；Second load transducer, 3 one end be fixed on carrying shell 1 outer bottom, the other end and be mounted on carrying shell 1
Outside under pull rod 6 connect.
The pulling force of the spring 4 be greater than or equal to the first load transducer 2 bearing capacity.
When the retention bead 7 is not contacted with carrying shell 1, the first load transducer 2 work, load value is carried by first
Lotus sensor 2 is read.
When the retention bead 7 and carrying shell 1 contacts, the work of the second load transducer 3, load value is by the second load
Sensor 3 is read.
The solution have the advantages that: it is not only able to satisfy in same mechanics device using the device to large span load capacity
The demand of journey, and automatic classification can be carried out in implementation process, operation link is simplified, is improved work efficiency, is reduced
Labor intensity.
Detailed description of the invention
Fig. 1 is automatic classification load feedback device schematic diagram；
Wherein, 1-carrying shell, the 2-the first load transducer, the 3-the second load transducer, 4-springs, 5-pull-up
Bar, 6-lower pull rods, 7-retention beads.
Specific embodiment
The present invention will be further described with reference to the accompanying drawings and examples:
Such as in the load test to certain testpieces, four kinds of operating conditions with sequencing are as follows: adding to testpieces
Force value is carried to be 1 ton, to the load force value of testpieces be 15 tons, be 1.5 tons to the load force value of testpieces, the load to testpieces
Force value is 18 tons.
Current mode of operation is:
The first step, when the load force value to testpieces is 1 ton hour, needing to choose range ability is 0-2 tons of sensor；
Second step, when the load force value to testpieces is 15 ton hours, needing replacing range ability is 0-25 tons of sensor
Third step, when the load force value to testpieces is 1.5 ton hours, needing replacing range ability is 0-2 tons of sensor；
4th step, when the load force value to testpieces is 18 ton hours, needing replacing range ability is 0-25 tons of sensor.
In test, operating condition sequence has determined and can not adjust, and testing crew is needed to carry for the test under every kind of operating condition
Lotus frequently replaces the sensor of different ranges, if under the premise of tested number is big, frequently replacement influences working efficiency, and
Testing crew labor intensity is high.
And automatic classification load feedback device of the invention is used, it can adapt in test that load range span is big to be wanted
It asks, avoids for needing the load for frequently replacing the pressurized strut of different ranges under different operating conditions.For this test process, using
In automatic classification load feedback device of the invention, the range that can choose the first load transducer based on experience value is 0-2 tons,
For small-range load transducer；The range of second load transducer is 25 tons, is wide range load transducer.Pass through small-range
The acquisition of load value is realized in the working condition switching of second load transducer of the first load transducer and wide range.Without
The sensor of different range abilities is frequently replaced according to operating condition sequence.
Automatic classification load feedback device schematic diagram is as shown in Figure 1, in use, the present apparatus is concatenated by the pull rod at both ends
In the bearing structure tested.When the load of application is no more than the 2 tonnage value of range of the first load transducer, small-range
The work of first load transducer, device load value feed back to examination by the first load transducer being connected between spring and upper connecting rod
Test personnel.
With the increase of test load, spring elongation, upper connecting rod is gradually moved up, the retention bead on upper connecting rod with hold
Carry shell contact.When test load is greater than the range of the first load transducer, device load value is by being connected to carrying shell bottom
Second load transducer of the wide range between portion and lower pull rod feeds back to testing crew.
The pulling force of spring will meet the ability to bear more than or equal to first sensor in device: when spring is stretched, on
Pull rod gradually moves up, and when load approaches or arrives at 2 tons of range of force value of the first load transducer, retention bead is just
It is contacted with load-carrying covering, to guarantee that the first load transducer nonoverload is advisable.
The present invention can equally be well applied to other test cases not just for experiment above scene: for example carry out height
In overload test, the loaded load of different testpieces is different, and traditional way is that each test front and back is needed according to different
Test load frequently replaces the sensor of corresponding different ranges, and automatic classification load of the invention is utilized to feed back dress
It is especially prominent to set working efficiency promotion.
The invention proposes a kind of automatic classification load feedback device, which is not only able to satisfy in same mechanics device
Demand to large span load range, and automatic classification can be carried out in implementation process, operation link is simplified, is greatly mentioned
High working efficiency, reduces labor intensity.
