In a specific embodiment, a kind of device stress testing tool is present embodiments provided, specifically, the device pressure
Power testing tool includes upper holder block, lower lock block 2, driving device 1 and slide plate 3,
Wherein upper holder block and lower lock block 2 are used to be respectively placed in the both ends of device 10, and under wherein driving device 1 is for driving
Briquetting 2 and upper holder block relatively move so that upper holder block and lower lock block 2 are jointly to the pressure pressure of device 10, it should be noted that its
In a upper holder block and a lower lock block 2 can be considered as and constitute one group of squeeze unit, when can have multiple groups extruding in the tool
Unit, and multiple groups are stacked up and down, to test simultaneously multiple devices 10, not to the number of upper holder block and lower lock block 2 at this
It is specifically limited.Wherein driving device 1 can be electric cylinders, can also be telescoping cylinder, such as telescopic hydraulic cylinder and flexible pneumatic cylinder.When
It should ensure that, wherein upper holder block and lower lock block 2 are energization briquetting, can be connected to busbar in advance generally to facilitate access electric system
In.
There is the placed mesa for mask placement device 10, it should be noted that can be on placed mesa on the upside of its middle slide plate 3
It is provided with positioning device, mounting table and device 10 can also be made to protect by the stiction between placed mesa and device 10
Hold relatively-stationary relationship.It also needs to guarantee, should be able to be conductive mutually when the upper surface of downside and lower lock block 2 contacts, i.e.,
The material for showing slide plate 3 and lower lock block 2 should be conductive material, and should can be conductive when being in contact.Show wherein
Upper holder block, device 10, slide plate 3 and lower lock block 2, which can sequentially form, to be conducted.
Its middle slide plate 3 should also be able to opposite 2 transverse shifting of lower lock block, so that slide plate 3 is able to drive device 10 from placement
Position is to test position, it should be noted that wherein test position is referred to when device 10 is located at the position, is driven at this time
The work of device 1 can make upper holder block and lower lock block 2 just push down device 10, so that device 10 is able to carry out test.Wherein place
Position refers in the position, device 10 is directly placed on placed mesa with can be convenient, and specific placement location can
From the point of view of being the easy degree being placed on placed mesa according to device 10, because space between upper holder block and lower lock block 2
Limitation, wherein placement location should can be set side by side in transverse direction with upper holder block, i.e., in vertical direction, there is no overlappings

On 2, can also install on the relatively-stationary component of lower lock block 2 so that sliding rail 5 can keep relative stability with lower lock block 2
Positional relationship.Wherein sliding rail 5 can be made insulation, also can be set into it is nonisulated, in order to guarantee safety, herein preferably
Sliding rail 5 is epoxy resin sliding rail 5.
Slide plate 3 is being moved along sliding rail 5, when so that device 10 entering test position, in order to avoid excessive sliding, is being caused
Deviate, can be set for being slided in slide plate 3 to drive the positioning for preventing slide plate 3 from continuing sliding after device 10 to test position
Device.The specific positioning device can be limited wall.In order to facilitate later period adjustment, it can be provided with location hole on slide plate 3,
And positioning device is then the ground elastic positioning pin that is slidably matched with location hole, and when the thrust that slide plate 3 is born is less than predetermined value, elasticity
Positioning pin can prevent location hole from radially sliding, and then slide plate 3 be prevented to slide, it should be noted that predetermined value should root
Determine according to manpower thrust size, generally 5 Ns or so, only needs manpower that can experience resistance.Wherein elastic positioning pin can
King positioning pin is thought, to guarantee flexibility.
It is considered that, in order to guarantee the service life of slide plate 3 Yu pressing plate 7, Ying Jinliang avoids two during moving slide board 3
Person's relative friction is based on this, can make have certain interval between slide plate 3 and lower lock block 2, and between slide plate 3 and lower lock block 2
It is provided with slide plate Flexible Reset device 4, slide plate Flexible Reset device 4 can be deformed in vertical direction to prevent slide plate 3 and push
Block 2 is in contact, it should be noted that when squeezing test, under extruding force effect, slide plate Flexible Reset device 4 should can
Deformation, so that slide plate 3 is in contact to realize and conduct with lower lock block 2.I.e. when starting moving slide board 3, slide plate 3 and lower lock block 2
Between can have certain gap, avoid phase mutual friction.Wherein, slide plate Flexible Reset device 4 is arranged in slide plate 3 and pressing plate 7
Between, not surface both ends are directly connect with slide plate 3 with lower lock block 2 respectively, and it can also be and be indirectly connected with, when sliding rail 5 is such as set,
The one end for acting on slide plate 3 on slide plate Flexible Reset device 4 can be made directly to be connected with sliding rail 5.In order to guarantee the stabilization of structure,
At least two slide plate Flexible Reset devices 4 can be provided in the lower section of every sliding rail 5.It should also be noted that, wherein sliding
Sheet reset elastic device 4 can be spring or other elastic structures.
Further, it is pushed into and pulls out for convenience slide plate 3, can be in the side of slide plate 3, and be preferably provided on the outside
Grip hole 51, grip hole 51 refers to that hole section at least guarantees to refer to four and is put into the hole, is pulled with facilitating.
Further, it is contemplated that upper holder block and lower lock block 2 have certain electric conductivity, in order to guarantee other structures safety,
It can make that bottom plate 6 and pressing plate 7 is arranged, and the upside of bottom plate 6 is provided with lower lock block 2, the downside of pressing plate 7 is provided with lower lock block
2, and then driving device 1 can be made to directly drive pressing plate 7 and pushed.It should be noted that in order to improve working efficiency, and mention
Height can be provided at least one intermediate plate 8 with batch test result precision again, and be fixed with upper pressure in the upside of intermediate plate 8
Block, and lower lock block 2 is fixed on the downside of it, when an intermediate plate 8 is only arranged, the lower lock block of the downside on such intermediate plate 8
2, the upper holder block common combination with 6 upside of bottom plate, to form a squeeze unit, to be respectively placed in the both ends of a device 10,
The formation of device 10 is squeezed, while the upper holder block of 7 downside of the lower lock block 2 of 8 upside of intermediate plate and pressing plate is combined into an extruding list
Member, when there are at least two intermediate plates 8, upper holder block and lower lock block 2 between two neighboring intermediate plate 8 constitute extrudings singly
Member.When in use, the extruding force that two devices 10 are subject to up and down tested simultaneously can be made equal in magnitude.
In driving pressing plate 7 downwards, and when intermediate plate 8 being driven to move down, in order to guarantee ride comfort, it can be set and led
Bar, guide rod and bottom plate 6 are relatively fixed, and guide rod and top board 7 and centre are slidably matched along the vertical direction.
When completing test, it can make to be moved up by driving device 1 with dynamic pressure plate 7, so that adjacent upper holder block is under
There is biggish gap, to facilitate push-in device 10 between briquetting 2.But when with intermediate plate 8, driving device 1 is then at this time
Driving is more inconvenient, is based on this, can be between intermediate plate 8 and bottom plate 6, and briquetting reset is provided between pressing plate 7
Elastic device 9, with squeeze when, deformation and energy storage, and driving device 1 reply initial position when, discharge elasticity can, make upper holder block
There is enough gaps between lower lock block 2.
