Description
Technical field
The utility model relates to technical field of lithium-ion battery, particularly relates to a kind of safety valve of cylindrical lithium-ion battery pressure test device.
Background technology
Current existing safety valve of cylindrical lithium-ion battery pressure test great majority are the modes taking sample preparation to be separated with pressure test, and above-mentioned mode cannot meet the safety valve testing requirement of high-energy type battery.Subject matter is: 1) process of complete paired samples is in the perforate of battery wall portion, due to each, independent tap operation is carried out to sample, on battery container, the deformation of the position of perforate, the size in hole and position of opening is all different, and this just causes safety valve pressure testing differentia; 2) sample need be put into proving installation during pressure test, in the process of placing, the position in hole and the relative position of proving installation build-in test carrier inlet cannot be fixed, and cause safety valve pressure testing differentia further.The basic reason of the problems referred to above is: do not have a kind of proving installation that can realize sample preparation and pressure test one.Because safety valve is most important for the security performance of high energy lithium ion cell, therefore develop a kind of can realize sample preparation and pressure test one device very necessary.
Utility model content
The purpose of this utility model is the deficiency overcoming above-mentioned technology, and provides a kind of safety valve of cylindrical lithium-ion battery pressure test device, realizes test sample preparation and test integrated, thus increases precision and the accuracy of test.
The utility model for achieving the above object, by the following technical solutions: a kind of safety valve of cylindrical lithium-ion battery pressure test device, it is characterized in that: comprise pressure test device and be fixed on the perforating device of its side, described pressure test device comprises side stamping tooling, upper holder block, lower lock block and joint, described joint is fixed on the side of described side stamping tooling, described upper holder block and lower lock block arrange the both sides up and down of described side stamping tooling respectively, and are connected by set bolt; Described perforating device comprises perforating needle, pressing plate and perforating needle handle, and described pressing plate is fixed on the opposite side of described side stamping tooling, and described perforating needle one end is through described side stamping tooling and pressing plate, and the other end is connected with described perforating needle handle.
Described perforating needle is provided with caging bolt.
The beneficial effects of the utility model are: the utility model structure is simple, 1) simplify the operation, raise the efficiency 2) punching consistance good, punching size controls 3 by fixed journey system) artificial loading otherness can be avoided to cause pressure test affect 4) frock is stable, structure is simple, easy to maintenance.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is stereographic map of the present utility model.
Embodiment
Embodiment of the present utility model is described in detail below in conjunction with accompanying drawing and preferred embodiment.As shown in Figure 1, a kind of safety valve of cylindrical lithium-ion battery pressure test device, comprise pressure test device and be fixed on the perforating device of its side, described pressure test device comprises side stamping tooling 1, upper holder block 2, lower lock block 4 and joint 5, described joint is fixed on the side of described side stamping tooling, described upper holder block and lower lock block arrange the both sides up and down of described side stamping tooling respectively, and are connected by set bolt 11,8; Described perforating device comprises perforating needle 7, pressing plate 6 and perforating needle handle 9, and described pressing plate is fixed on the opposite side of described side stamping tooling, and described perforating needle one end is through described side stamping tooling and pressing plate, and the other end is connected with described perforating needle handle.Described perforating needle is provided with caging bolt.In test Sample Cell embedding device, fastening bolt 8,11, turn perforating needle handle 9, is threaded to caging bolt 10 and reaches nearly bolt 8 end end of travel, reverse turn punch handle 9, is threaded to bolt 10 to bolt 8 end end of travel far away, carries out pressure test.
The utility model structure is simple, 1) simplify the operation, raise the efficiency 2) punching consistance is good, punching size controls 3 by fixed journey system) artificial loading otherness can be avoided to cause pressure test affect 4) frock is stable, structure is simple, easy to maintenance.
The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
