Side is equipped with hermatic door, connect at the top of hermatic door with top plate seal, realizes the sealing to extrusion chamber (3) by hermatic door, so that squeezing
Pressure chamber (3) is in sealing state.
3. a kind of working method of battery extrusion testing device according to claim 1, which is characterized in that specific works mistake
Journey is as follows:
The first step chooses four same same type of tested batteries of model, and battery is placed in the slot in protection block cover (27)
Take turns support plate (26) surface；
Then second step opens decelerating motor and drives first rotating shaft (21) rotation, drives and dial in first rotating shaft (21) rotation process
Disk (22) rotation, the pin rod (223) of fixed strip (222) surface side are just inserted into bar shaped pulling hole (262), are turned in driver plate (22)
When dynamic, sheave support plate (26) are pushed to rotate in bar shaped pulling hole (262) by pin rod (223), until pin rod (223) produces item
Shape pulling hole (262) drives the second shaft (25) to rotate, the second shaft in the process in sheave support plate (26) rotation process
(25) rotate gear (24) rotation is driven, rotate gear (24) band nutating gear (7) rotates, since transmission gear (7) are installed
It is fixed on sliding block (6), band movable slider (6) revolves on circular guideway (5) when transmission gear (7) is rotated around rotate gear (24)
Turn, realizes the synchronous rotation of transmission gear (7) and sheave support plate (26), the miniature support installed on transmission gear (7) at this time
Hydraulic cylinder (8) and transmission gear (7) and sheave support plate (26) rotate synchronously, and realize that the support to sheave support plate (26) is solid
It is fixed；
Third step, the protection block cover (27) when pin rod (223) produces bar shaped pulling hole (262) positioned at the rightmost side are placed exactly in door
(13) underface, and the top of block cover (27) and the bottom surface of door (13) is protected to connect, so that in the protection block cover (27)
Enclosure space is formed, one of arc lock plate (221) is just transferred to one when pin rod (223) produces bar shaped pulling hole (262)
In a arc lock groove (261), the side wall of arc lock plate (221) connects with the side wall of arc lock groove (261), arc locking
Disk (221) is just connected in arc lock groove (261), realizes the locking to sheave support plate (26), at this time sheave support plate
(26) locking is motionless, and the pressure end of control standard dynamometer (4) is worn during sheave support plate (26) locking is motionless
Open-work (131) is depressed into the battery surface in protection block cover, applies pressure to 17MPa, then controls the pressure of standard dynamometer (4)
End is shunk until being pierced by through hole (131), completes the extruding of first battery at this time；
4th step, after the first battery extrusion, arc lock plate (221) just produces arc lock groove (261), fixed strip
(222) pin rod (223) of the surface other side is just inserted into bar shaped pulling hole (262), when driver plate (22) rotate, passes through pin rod
(223) sheave support plate (26) are pushed to rotate in the bar shaped pulling hole (262), until pin rod (223) produces bar shaped pulling hole (262),
Sheave support plate (26) rotation at this time is placed exactly in the underface of door (13) to the protection block cover (27) of the rightmost side, works as pin rod
(223) another arc lock plate (221) is just transferred in an arc lock groove (261) when producing bar shaped pulling hole (262), arc
Shape lock plate (221) is just connected in arc lock groove (261), realizes the locking to sheave support plate (26), at this time sheave
Support plate (26) locking is motionless, and the pressure end of standard dynamometer (4) is controlled during sheave support plate (26) locking is motionless
It is depressed into the battery surface in protection block cover across through hole (131), 17MPa is applied pressure to, then controls standard dynamometer (4)
Pressure end shrink until being pierced by through hole (131), at this time complete second battery extruding；
5th step, and so on, then it is respective to be taken out measurement by the automatic extruding realized to four pieces of same batteries for four pieces of batteries
Voltage is compared.
