Abstract
The utility model relates to the battery field, in particular to a battery steel ball seal device in the process of sealing the battery by the steel ball. The device is composed of a top head used for connecting with a pressing machine, and a pressure head of a steel-pressing ball which is arranged at the lower end of the top head, and the pressure head is provided with an elastic part. With adopting the technical proposal, the utility model provides the battery steel ball seal device which can effectively prevent a battery shell from being damaged because of the overpressure from the pressure head.
Description
Technical field
The utility model relates to field of batteries, relates in particular to a kind ofly with steel ball battery is being sealed employed battery steel ball closing device in the process.
Background technology
In the battery production process, after battery is finished the fluid injection detection, need at last liquid injection hole is sealed, usually the sealing means that we adopted is to seal with steel ball, again by a kind of steel ball closing device that steel ball is exerted pressure, steel ball is pressed in the battery, thereby plays sealing function.
But in this course, existing pressure head all is to adopt rigid pressure head, promptly directly pressure head is fixed on the forcing press by the top, the control of its pressure size is fully by artificial feel, and easily the battery top being pressed of therefore existing collapsed, pressure break and in use must the careful operation of extreme care and cause problem such as work fatigue easily.
The utility model content
For solving the problems of the technologies described above, the utility model provides a kind of and can prevent effectively that ram pressures is excessive and damage the battery steel ball closing device of battery container.
The utility model is achieved through the following technical solutions: a kind of battery steel ball closing device, comprise being used to the pressure head that connects the top of forcing press and be arranged on its lower end compressed steel pearl, and on the described pressure head elastic component is set.
Further, the utility model also comprises following content:
Described elastic component is arranged between described pressure head and the described top.
Described elastic component comprises spring housing and the spring of the portion that sets within it.
Described spring housing both ends open, described top are fixed on a wherein end of described spring housing, the mobilizable other end that is arranged on described spring housing of described pressure head.
The end that described pressure head is arranged in the described spring housing has the protuberance that matches with described spring housing port, prevents that pressure head breaks away from from described spring housing.
Lower end, described top is provided with inner core.
The beneficial effects of the utility model are: owing to be provided with elastic component on pressure head, the distortion that makes full use of elastic component is guaranteed to carry out the approximately constant that steel ball seals the pressure that produces in the process at this device, promptly in pressure head compressing steel ball advances process, when its front end is subjected to counter-pressure that the battery container transmission returns, therefore pressure head will effectively overcome original rigid pressure head fully by easily battery top pressure being collapsed that artificial feel controlled pressure is caused along with the contraction of the spring that forces are applied to moving in the other direction, thereby pressure break and must the careful operation of extreme care cause problems such as work fatigue easily in use.
Description of drawings
Fig. 1 is the overall structure schematic diagram of the utility model specific embodiment.
Fig. 2 is the cross-sectional view of the utility model specific embodiment.
Embodiment
The utility model is described in further detail below in conjunction with embodiment.
As shown in Figure 1, 2, be the specific embodiment of battery steel ball closing device of the present utility model.This kind battery steel ball closing device comprises and is used to connect the top 1 of forcing press and is arranged on the pressure head 5 that 1 lower end, top is used for piezoelectricity pond steel ball, on described pressure head 5 elastic component is set.Adopt the battery steel ball closing device of above structure, owing on pressure head, be provided with elastic component, the distortion that makes full use of elastic component is guaranteed to carry out the approximately constant that steel ball seals the pressure that produces in the process at this device, promptly in pressure head compressing steel ball advances process, when its front end is subjected to counter-pressure that the battery container transmission returns, therefore pressure head will effectively overcome original rigid pressure head fully by easily battery top pressure being collapsed that artificial feel controlled pressure is caused along with the contraction of the spring that forces are applied to moving in the other direction, thereby pressure break and must the careful operation of extreme care cause problems such as work fatigue easily in use.
Described elastic component is arranged between described pressure head 5 and the described top 1; Described elastic component comprises the spring 3 of the spring housing 4 and the portion that sets within it, spring housing 4 two ends are opening, one end is used for fixing top 1, the other end inserts described pressure head 5 movably, spring 3 just has been arranged between top 1 and the pressure head 5 like this, and when being subjected to external pressure, pressure head 5 and spring 3 are subjected to the pressure of two directions up and down respectively, because movable pressure head 5 matches with flexible springs 3, thereby on pressure head, form the pressure of approximately constant.
The end that pressure head 5 is arranged in the spring housing 4 has the protuberance that matches with described spring housing 4 ports, can prevent that like this pressure head 5 breaks away from from described spring housing 4 in motion process.
Come directly towards 1 lower end inner core 2 is set, make inner core 2 be arranged in the central ring of spring 3, when the longitudinal pressure that is subjected to when spring 3 is excessive, produce big compression, and inner core 2 plays the supporting role to spring, thereby realized protection spring.
Yet the above is a preferred embodiment of the present utility model only, is not so limits to scope of the present utility model, and equivalences that all utilization the utility model description are carried out change, and all in like manner are included in the scope of the present utility model.
