Description
Technical Field
The utility model relates to a battery package upper end cover casing gas tightness detects frock belongs to battery package upper cover check out test set technical field.
Background
The power battery pack is a power source in the new energy automobile, is provided with a firm and sealed metal shell box body, contains components such as a battery module, a BMS, a BEC and a bus and is sealed by an upper cover plate of the battery pack. The battery box body is sealed and waterproof, so that a short circuit caused by water inflow is prevented, the working safety of a battery system is directly influenced by the sealing performance of the battery box body, and the protection grade of the battery box body is required to reach IP67.
Therefore, when the upper cover of the battery pack is produced, the air tightness of the upper cover is one of important indexes for measuring the quality of the upper cover, and therefore, the air tightness is an important basic detection item for the air tightness test of the upper cover. When the air tightness detection is carried out, the periphery of the bottom of the upper cover and through holes on the top surface of the upper cover need to be sealed, then pressure air is introduced into a sealed space, the air tightness of the upper cover is judged according to the air leakage condition, the existing air tightness detection tool for the upper cover has the defects that a sealing rubber strip is easy to dislocate and damage after multiple times of pressing operation, the service life is short, the position of the rubber strip needs to be adjusted and recovered frequently, and the detection efficiency is influenced; the upper cover closing device all around mostly is manual compresses tightly one by one or local segmentation compresses tightly, and the upper cover is all around compressed force evenly inadequately, influences sealed effect, and anchor clamps are in large quantity, operates numerous and diverse, and detection efficiency is lower.
Disclosure of Invention
An object of the utility model is to overcome the aforesaid not enough, provide a simple structure, joint strip longe-lived, compress tightly easy operation, detection efficiency is high battery package upper end cover casing gas tightness and detect frock.
The purpose of the utility model is realized like this:
a battery pack upper end cover shell airtightness detection tool comprises an underframe, a workbench mounted on the underframe, and a clamping device mounted on the workbench, wherein a contact body is further mounted on the workbench, an annular groove with a rectangular cross section is formed in the contact body, a silica gel sealing strip with a rectangular cross section is embedded in the groove, and the height of the sealing strip is slightly higher than the surface of the groove; a frame type integral pressing strip is arranged on the top surface of the periphery of the upper cover, and is pressed through a clamping device, and the clamping device is a pneumatic control rotary pressing cylinder.
Further, the sealing strip is 1 mm higher than the groove surface of the contact body.
Furthermore, the contact body is made of 5120 substituted wood.
Furthermore, the pressing strip is made of aluminum alloy.
Furthermore, a plug and an air inlet pipeline are arranged on the through hole on the top surface of the upper cover.
Furthermore, universal wheels are installed on the underframe.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model arranges the rectangular groove on the contact body at the bottom of the upper cover and embeds the rectangular silica gel sealing strip, so that the sealing strip is always kept in the rectangular groove without sliding when being pressed, thereby avoiding the abnormal pressure damage of the sealing strip; the frame type integral pressing strip is arranged on the peripheral top surface of the upper cover, and the pressing strip is compressed through the pneumatic control rotary compression cylinder, so that the periphery of the upper cover is uniformly pressed, the sealing effect is good, the surface quality of the upper cover is not influenced, the operation is simple, and the detection efficiency is improved.

Fig. 1 is the utility model discloses a three-dimensional structure schematic diagram of battery package upper end cover casing gas tightness detects frock.
Fig. 2 is the utility model relates to a battery package upper end cover casing gas tightness detects local enlarged structure sketch map of frock.
Fig. 3 is the utility model relates to a sealing strip installation section structure sketch map of frock is detected to battery package upper end cover casing gas tightness.
Wherein:
the device comprises an underframe 1, a workbench 2, a clamping device 3, a contact body 4, a universal wheel 5, a sealing strip 6, a pressing strip 7, a plug 8, an air inlet pipeline 9 and an upper cover 10.
Detailed Description
Referring to fig. 1 to 3, the utility model relates to a battery pack upper end cover shell airtightness detection tool, which comprises an underframe 1 provided with a universal wheel 5, a workbench 2 arranged on the underframe 1, and a clamping device 3 arranged on the workbench 2, wherein the workbench 2 is also provided with a contact body 4 made of 5120 materials, the contact body 4 is provided with an annular groove with a rectangular cross section, a silica gel sealing strip 6 with a rectangular cross section is embedded in the groove, and the height of the sealing strip 6 is 1 mm higher than the surface of the groove; a frame type integral aluminum alloy pressing strip 7 is arranged on the peripheral top surface of the upper cover 10, the pressing strip 7 is pressed tightly through a clamping device 3, and the clamping device 3 is a pneumatic control rotary pressing cylinder; and a plug 8 and an air inlet pipeline 9 are arranged on a through hole on the top surface of the upper cover 10.
When detecting the air tightness of the upper end cover of the battery pack, the upper cover 10 is placed on the contact body 4, the bottom of the periphery of the upper cover 10 is in contact with the sealing strip 6, the integral aluminum alloy pressing strip 7 is placed on the top surface of the periphery of the upper cover 10, the clamping device 3 is started, namely, the rotary pressing cylinder is rotated, the movable end pressure head of the rotary pressing cylinder is rotated and pressed down on the pressing strip 7, the plug 8 and the air inlet pipeline 9 are installed at the through hole position of the top surface of the upper cover 10, the air leakage detector is started to introduce air into the air inlet pipeline 9 for pressurization, and the air leakage condition is detected.
