Abstract
The utility model discloses a cylindrical lithium battery pressing clamp, which comprises a pressing clamp body, wherein the pressing clamp body is of a cylindrical structure, a pointed steel needle is inserted into the wall of one side of the cylinder, the steel needle is of a hollow structure, the steel needle is connected with a gas pipe by the needle tail of one side outside the cylinder, and a rubber pad is coated around the needle head of one side inside the cylinder; a T-shaped bolt is arranged on the wall of the other side of the cylinder opposite to the steel needle, and the head of the bolt close to one side in the cylinder is movably connected with an arc-shaped gasket, namely the bolt is screwed, and the gasket does not rotate along with the bolt. The utility model discloses the effectual gas tightness problem of having solved existence among the prior art, the steel needle of drilling directly links to each other with the trachea to because the steel needle syringe needle is less than the rubber pad surface a little, before the syringe needle bores through the battery, the rubber pad has guaranteed the gas tightness around the syringe needle, convenient operation, respond well.
Description
Technical field
This utility model belongs to lithium battery production technical field, relates to a kind of fixture, particularly to be that a kind of cylindrical lithium battery suppresses fixture.
Background technology
The production of lithium battery needs through operations such as cover plate welding, liquid injection hole sealings, and its purpose is contemplated to isolation and extraneous mass exchange.Therefore, weld and the effect sealed has vital impact to the end properties of lithium battery.In actual production process, need to detect cover plate welding, the intensity of sealing and air-tightness.The method that current technology typically uses is first to be holed by battery, then trachea is filled with the gas of certain pressure, is immersed in the water, detection battery cover board welding, the intensity of sealing and air-tightness.This kind of operation has a problem in that first to hole and detects, separate operations, and step is relatively complicated, it is often more important that trachea, the very difficult solution of the air-tightness of seam again after boring.
Utility model content
For the deficiencies in the prior art, the utility model proposes a kind of cylindrical lithium battery and suppress fixture.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of cylindrical lithium battery suppresses fixture, including suppressing chuck body, suppressing chuck body is cylindrical structure, the draw point of interspersed tip on the barrel of cylinder side, draw point is hollow-core construction, draw point is connected with trachea by the backshank of the outer side of cylinder, and draw point is by being coated with rubber blanket around the syringe needle of side in cylinder, and syringe needle is more lower slightly than rubber blanket surface；Having a T-slot bolt with on the cylinder opposite side barrel on draw point opposite, bolt connects one piece of arc spacer by the head movement of side in cylinder, i.e. turns bolt, and pad does not and then rotate.
The draw point of interspersed tip on the barrel of described cylinder side, draw point is hollow-core construction, and draw point is connected with trachea by the backshank of the outer side of cylinder.
Described draw point is by being coated with rubber blanket around the syringe needle of side in cylinder, and syringe needle is lower than rubber blanket surface.
Having a T-slot bolt on the described cylinder opposite side barrel with draw point opposite, bolt connects one piece of arc spacer by the head movement of side in cylinder, i.e. turns bolt, and pad does not and then rotate.
The beneficial effects of the utility model: this utility model effectively solves air-tightness problem, the draw point of boring is joined directly together with trachea, and owing to draw point syringe needle is slightly below rubber blanket surface, before pin drill energising pond, rubber blanket ensure that the air-tightness around syringe needle, easy to operate, respond well.
Accompanying drawing explanation
Below in conjunction with the accompanying drawings this utility model is further described for the ease of it will be appreciated by those skilled in the art that.

Fig. 2 this utility model cross-sectional schematic.
Labelling in figure: 1-suppresses chuck body, 2-arc spacer, 3-T-slot bolt, 4-rubber blanket, 5-draw point, 6-trachea, 7-cylindrical lithium battery.
Detailed description of the invention
As shown in Figure 1, 2, a kind of cylindrical lithium battery suppresses fixture, including suppressing chuck body 1, suppress chuck body 1 for cylindrical structure, interting on the barrel of cylinder side and have acuminous draw point 5, draw point 5 is hollow-core construction, and draw point 5 is connected with trachea 6 by the backshank of the outer side of cylinder, draw point 5 is by being coated with rubber blanket 4 around the syringe needle of side in cylinder, and syringe needle is more lower slightly than rubber blanket surface.Being provided with a T-slot bolt 3 with the cylinder barrel of draw point 5 opposite face, bolt connects one piece of arc spacer 2 by the head movement of side in cylinder, i.e. turns bolt, and pad does not and then rotate.
nullAt work，Cylindrical lithium battery 7 is put into and suppresses in chuck body 1 cylinder，Draft bore position alignment draw point 5 syringe needle，Turn T-slot bolt 3，T-slot bolt 3 moves to cylinder interior direction，Arc spacer 2 is flexibly connected with T-slot bolt 3，Do not rotate with T-slot bolt 3，But under the promotion of T-slot bolt 3，Promote cylindrical lithium battery 7，Cylindrical lithium battery 7 opposite side extruding rubber blanket 4 and draw point 5，Rubber blanket 4 pressurized，Tightly against cylindrical lithium battery 7 surface，But draw point 5 is integrally fixed on cylinder，Along with T-slot bolt 3 promotes arc spacer 2 to extrude cylindrical lithium battery 7，Cylindrical lithium battery 7 is punctured by draw point 5，Cylindrical lithium battery 7 inside and draw point 5，And the trachea of backshank forms connection，Compressed gas is pressed into inside cylindrical lithium battery，The welding of cylindrical lithium battery cover plate and the intensity of sealing and air-tightness can be tested.
Above content is only to this utility model structure example and explanation; described specific embodiment is made various amendment or supplements or use similar mode to substitute by affiliated those skilled in the art; without departing from the structure of utility model or surmount scope defined in the claims, protection domain of the present utility model all should be belonged to.
