Description
Technical field
The present invention relates to testing equipment field more particularly to a kind of handle strength detection devices.
Background technique
At present in breaker industry, the handle of omnipotent breaker manual energy storage is press-down type, and energy storage dynamics is larger,
Being easy to overexert when client's manual energy storage causes handle to be broken, therefore handle need to meet some strength requirement, and it is strong need to detect handle
Degree excludes rejected product；But it is internal during handle compression moulding to be also easy to produce bubble, therefore the individually impact of detection material sample block
Intensity can not really reflect the impact strength of handle.
Summary of the invention
In view of the above-mentioned problems, the present invention provides a kind of handle strength detection device.
To achieve the above object, the present invention provides a kind of handle strength detection device comprising operating platform, the operation
Mounting table is arranged in the side of platform, and the mounting table vertically operating platform setting, the side of the mounting table is set
There is at least one for fixing the positioning device of circuit breaker handle, and is set on the upside of the middle part of the operating surface in the circuit breaker handle
Set the cylinder assembly for pressing circuit breaker handle, the behaviour of the vertical circuit breaker handle of the force direction of the cylinder assembly
Make face setting, and the cylinder assembly is equipped with the regulating mechanism of adjustable amount of force.
The positioning device includes articulated shaft and limit shaft, and the articulated shaft is adapted with the turn hole of circuit breaker handle, institute
It states limit shaft and circuit breaker handle constitutes circumferential limit and cooperates.
The cylinder assembly includes cylinder and mandril, and the cylinder is connect with regulating mechanism.
Described mandril one end is equipped with rubber pad.
The regulating mechanism includes the adjusting knob for adjusting cylinder pressure.
The mounting table is equipped with air gauge, and the air gauge is connect with the regulating mechanism.
The operating platform is equipped with scram button and operation button for controlling cylinder moving state.
Beneficial effects of the present invention: giving circuit breaker handle simulating handle actual loading situation using cylinder assembly, can be with
Known inside circuit breaker handle during the test with the presence or absence of the damage that should not be discovered, avoids circuit breaker handle in manual energy storage
The case where being broken in the process causes product function to be lost.
Detailed description of the invention
Fig. 1 is structural representation Fig. 1 of the invention.
Fig. 2 is structural representation Fig. 2 of the invention.
Specific embodiment
The embodiment of the present invention is described further below for attached drawing:
The present invention provides a kind of handle strength detection devices comprising peace is arranged in the side of operating platform 1, the operating platform
Table top 2 is filled, vertically the operating platform setting, the side of the mounting table are equipped at least one for solid to the mounting table
Determine the positioning device of circuit breaker handle, circuit breaker handle is arranged in mounting table by positioning device, and the positioning device
Including articulated shaft 7 and limit shaft 8, the articulated shaft 7 is adapted with the turn hole of circuit breaker handle, the limit shaft and breaker hand
Handle constitutes circumferential limit cooperation, i.e., the turn hole of circuit breaker handle is hingedly arranged with articulated shaft, and by several limit shafts come
The limit circumferentially rotated for realizing circuit breaker handle, avoids deflecting in forces testing, influences detection effect, and limit
Position axis can use dismountable structure, can carry out different limit shaft installations, according to different circuit breaker handles to meet
The circuit breaker handle of different model detects, and several fixation holes can circumferentially be arranged using shaft, limit shaft is detachable with fixation hole
Setting, and articulated shaft uses the various sizes of diameter of axle, to meet the assembly of different circuit breaker handles.
And the cylinder assembly for pressing circuit breaker handle is set on the upside of the middle part of the operating surface in the circuit breaker handle
3, i.e., the operating surface of circuit breaker handle is arranged along the horizontal plane, the vertical breaker hand of the force direction of the cylinder assembly
The operating surface of handle is arranged, and the vertical operating surface of the active force of cylinder assembly is arranged, active force is made completely
With on circuit breaker handle, so that its detection data is more accurate, and the cylinder assembly is equipped with adjustable amount of force
Regulating mechanism, the regulating mechanism include the adjusting knob 4 for adjusting cylinder pressure, the adjustable cylinder of the adjusting knob
Pressure carries out pressure adjusting according to different circuit breaker handles, and can increase to change the impact force of entire cylinder assembly
Big pressure carries out destructive testing to circuit breaker handle, to realize multifunctional testing.
The cylinder assembly includes cylinder and mandril, and the cylinder is connect with regulating mechanism, and mandril is used to press breaker
Handle in order to avoid the impact of mandril keeps circuit breaker handle impaired, therefore is arranged rubber pad 6 in one end of mandril, increases buffering
Effect.
The mounting table is equipped with air gauge 5, and the air gauge is connect with the regulating mechanism, can be logical with real-time display
The pressure value of the cylinder after knob is adjusted is overregulated, and it is also possible that operator can more be apparent from test force
Degree.
