Description
Technical field
The utility model is related to a kind of weld strength test devices, and in particular to a kind of stator core welding tensile strength is surveyed
Trial assembly is put.
Background technology
Stator core is the important component for forming motor magnetic flux circuit and fixed stator coils, it is by punching and various fastenings
Part, which compresses, forms an entirety.Stator core is welded by iron core and gusset, and gusset is connected with electric machine stand, therefore, right
Stator core is welded with very high requirement.Once not prison welding is consolidated, it is possible to iron core be caused to be detached with gusset, directly contributed
Motor damage, seriously affects that product is safe to use, and therefore, it is necessary to the weld strengths to stator core to be measured, to ensure to weld
Quality is connect to comply with standard.But in the prior art, lack the device to stator core welding tensile strength test, it is common to stretch by force
Test machine is spent, and is not suitable for the test welded to stator core.
Utility model content
The purpose of this utility model is exactly to solve the above-mentioned problems and provides a kind of stator core welding tensile strength and survey
Trial assembly is put.
The purpose of this utility model is achieved through the following technical solutions：
A kind of stator core welds tensile strength test device, and including testing machine ontology, the testing machine ontology is by top
Stent and lower part platform composition, the platform be equipped with bottom plate, the bottom plate be equipped with for place stator core test
The lower die of sample, the lower die are equipped with the gripping block for locking stator core test sample, and the stent is equipped with
Crossbeam, the crossbeam lower end are equipped with electric lifting mechanism, and the electric lifting mechanism lower end is equipped with the upper pressure coordinated with lower die
Mould, the upper die presses down the iron core of stator core test sample under the driving of electric lifting mechanism to be divided until with gusset
From, measure its weld tensile strength.
Further, the electric lifting mechanism is fed for electric threaded shaft, electric lifting mechanism connection pressure sensor,
Pressure sensor connects storage device, and pressure value is recorded.
Further, the lower die is L-shaped, is fixed on bottom plate.
Further, in " recessed " type of falling, upper end is fixedly connected on electric lifting mechanism the upper die.
Further, the gripping block is connected with lower die, and the gusset on iron core is fixedly clamped by gripping block,
Ensure to prevent iron core gusset from deforming during pushing.
Further, the bottom plate is fixed by screws on platform.
When the present apparatus is specifically used, sample to be tested is placed on lower die, then test sample is locked with gripping block, is led to
It crosses upper die to press down iron core, be detached until with gusset, measure tensile strength during separation, you can easily realize to stator iron
Core welds the test of tensile strength.
The test that the utility model welds tensile strength for stator core provides a kind of test device easy to use, should
Device can be matched so that it is convenient to by stator core by the cooperation of upper die and lower die with the shape of stator core
Iron core detached with gusset, upper die upper end is driven by electric lifting mechanism, and on electric lifting mechanism set pressure pass
Sensor facilitates the tensile strength of accurate recording test process.This test device can improve the testing efficiency of product, reduce product not
Yield ensures product quality.
