Description

A kind of fluid injection machine clamp air tightness detection apparatus
Technical field
This utility model is related to technical field of lithium batteries and in particular to a kind of fluid injection machine clamp air tightness detection apparatus.
Background technology
At present, the fluid injection machine clamp being produced in use, easily causes aging, the damage of sealing member, Jin Erzao Become fixture poor sealing, produce a series of leakage, not fluid injection problem.Gas due to filling machine its fixture in maintenance process Close property can not and know, typically need to adopt manual maintenance method, that is, pass through spanner, diagonal cutting pliers, straight screwdriver, shears, interior six Not only workload is big for the method on one side by all tight for all seal nipples on fixture for the instruments such as angle, and efficiency low it is also possible to Because carelessness causes missing inspection so that spare part quality can not ensure.
Utility model content
The purpose of this utility model is to provide a kind of fluid injection machine clamp air tightness detection apparatus it is ensured that fixture quality can Lean on, improve work efficiency.
For achieving the above object, this utility model employs technical scheme below:
A kind of fluid injection machine clamp air tightness detection apparatus, including base and be fixed on support on base, described base set There is the mounting groove matching with fixture size, described support is provided with air tightness detection apparatus, Pneumatic adjusting mechanism and vacuum and occurs Device, described Pneumatic adjusting mechanism, vacuum generating device and air tightness detection apparatus are interconnected by threeway, pipeline, described gas Close detection means includes elastic valve and the control machine for controlling cylinder moving that cylinder is connected with the piston end of cylinder Structure, described elasticity valve is oppositely arranged with fixture valve.
In such scheme, described vacuum generating device is included vacuum generator and is connected with the outlet side of vacuum generator Vacuum meter, the vacuum end of described vacuum generator is connected with elastic valve, the inlet end of vacuum generator and air pressure adjustment Mechanism is connected.
In such scheme, described base is additionally provided with clamp positioning mechanism.
In such scheme, described detent mechanism is the projection matching with described fixture upper groove.
As shown from the above technical solution, fluid injection machine clamp air tightness detection apparatus described in the utility model and its detection side Method, achieves fixture by air tightness detection apparatus, Pneumatic adjusting mechanism and the vacuum generating device being fixed on base and support Air-leakage test, it is to avoid the situation that fixture leaks air in detection process occurs, and significantly improves the production efficiency of battery.
Brief description
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation after this utility model is installed with fixture cooperation.
Specific embodiment
Below in conjunction with the accompanying drawings this utility model is described further:
As shown in Figure 1, 2, the fluid injection machine clamp air tightness detection apparatus of the present embodiment, including base 10 and be fixed on base 10 On support 20, base 10 is provided with the mounting groove matching with fixture size, and support 20 is provided with air tightness detection apparatus, air pressure Governor motion 30 and vacuum generating device, Pneumatic adjusting mechanism 30, vacuum generating device and air tightness detection apparatus pass through threeway, pipe Road 80 is interconnected;Air tightness detection apparatus include elastic valve 42 that cylinder 41 is connected with the piston end of cylinder 41 and are used for Control the controlling organization 43 of cylinder 41 motion, as shown in Fig. 2 when mounted, elastic valve 42 and fixture valve 60 are oppositely arranged.
In the present embodiment, vacuum generating device includes vacuum generator 51 and the vacuum meter being connected with vacuum generator 51 52.This vacuum generator 51 has vacuum end, inlet end and outlet side, when mounted, the outlet side of this vacuum generator 51(I.e. Suction side)It is connected with vacuum meter 52, the inlet end of vacuum generator 51(I.e. positive pressure side)It is connected with Pneumatic adjusting mechanism 30, vacuum The vacuum end of generator 51 is connected with elastic valve 42.Clamp positioning mechanism is additionally provided with base 10, for convenience fixture Installation and fixation, this detent mechanism is the projection 70 matching with fixture upper groove.
Detection process is as follows:
S1:Tested fixture 90 is installed on base, opens air tightness detection apparatus;
S2:Open threeway suction side, close threeway positive pressure side;
S3:Open vacuum generating device, negative pressure led to tested fixture 90, if vacuum meter 52 display vacuum values be more than- 95kpa, then this tested fixture 90 air-tightness is qualified, if the vacuum values of vacuum meter 52 display are less than -20kpa, fixture air-tightness Unqualified;
S4:If tested fixture 90 air-tightness is unqualified, close vacuum generating device, open threeway positive pressure side, close three Logical suction side;
S5:Open Pneumatic adjusting mechanism, tested fixture 90 is led to the compressed air of 40kpa, produce bubble using suds Principle, thus accurately checking air leakage point, then keeped in repair accordingly;
S6:After the completion of maintenance, open vacuum generating device, negative pressure -95kpa is led to tested fixture 90, if vacuum tabular value is big In -95kpa, then tested fixture 90 air-tightness after keeping in repair is qualified.
Embodiment described above is only preferred implementation of the present utility model to be described, not to this practicality New scope is defined, and on the premise of without departing from this utility model design spirit, those of ordinary skill in the art are to this Various modifications and improvement that the technical scheme of utility model is made, all should fall into the protection of this utility model claims determination In the range of.
