Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a battery assembly method that improves the method of fixing a pole pole to which a group of electrode plates is attached to a turtle tank.

Ni--Cd batteries, which are generally used in aircraft, rockets, etc., have small storage compartments and are required to have high loads such as high capacity and large current.

For this reason, pole poles and haze tanks that make up batteries have become smaller, and instead of the conventional structure of pole poles, which are fixed with bulky bolts and nuts, there is a search for a structure that is fixed using a stop theory. It's here. Those with a structure that is fixed using a retaining ring are difficult to assemble because the fixing parts such as the O-ring, washer, and retainer are small, and the electrode plates and separators may be damaged during work. The problem was that special scissors had to be used to spread the stop theory formed, making automation difficult and time consuming.

In addition, if the fixed parts are not installed vertically enough, the electrolyte may leak outside from the fixed part of the pole pole and the turtle tank lid.Especially when the battery capacity is large and the weight of the electrode plate group increases, the electrolyte may leak. There was a drawback that it became easier. As a result of various research conducted in view of these points, the present invention improves assembly workability, significantly shortens work time, facilitates automation, prevents damage to electrode plates and separators, and prevents damage to liquids. This was created after discovering a battery assembly method that prevents leakage.

That is, in the method of the present invention, the upper part of the pole pole to which the pole plate group is attached is passed through the upper surface of the box lid, and fixing parts such as O-rings and washers are inserted therein, and a hollow cut is inserted in the upper part of the pole pole. After re-laying the auxiliary metal fitting with a conical head shape and inserting a retaining ring into the auxiliary metal fitting to support it, attach the tip of the bolt of the jig, in which the pressure block is attached to the bolt so that it can be raised and lowered, to the auxiliary metal fitting. Then, lower the pressurizing block and press down the retaining ring supported by the auxiliary bracket to insert the iron fitting into the annular groove formed at the tip of the pole. It is characterized by being fixed in place. The present invention will be described in detail below with reference to the drawings.

1 to 4 show one method of the present invention. In the figures, 1 is a pole pole, and a flange portion 2 is provided at the bottom of the pole pole 1.
is formed, and the electrode plate group 3 is attached to the bottom thereof by welding or bolting. Furthermore, a threaded hole 4 for attaching a bushing pestle is opened at the tip of the pole post 1, and an annular groove 5 is formed in the green circumference of the tip side. Reference numeral 6 denotes a dew tank lid, and an insertion hole 7 is provided in the center of the lid, and the upper part of the pole column 1 passes through the insertion hole 7 through a packing 8 provided on the flange portion 2 to reach the upper surface of the haze tank lid 6. It's starting to stand out.

Also, 9 is a ring, 10 is a flat spring washer, 11 is a washer,
Reference numeral 12 indicates a retaining ring, and reference numeral 13 indicates an auxiliary metal fitting.

As shown in FIG. 2, this auxiliary fitting 13 is formed into a hollow truncated conical shape, the outer diameter of the upper part is smaller than the inner diameter of the retaining ring 12, and the outer diameter of the lower part is smaller than the outer diameter of the upper part of the pole column 1. It is formed approximately equal to the outer diameter. Incidentally, the hollow may have a threaded groove engraved on its inner wall to form a threaded hole in the same position as the threaded hole 4 at the tip of the pole column. Reference numeral 14 denotes a jig, in which a bolt 17 is vertically inserted into the center of a pressurizing block 16 having a groove 15 at the bottom, and the pressurizing block 16 is screwed into the pressurizing block 16 so as to be able to move up and down. It is something. Next, to explain the assembly method, after storing the pole pole 1 with the pole plate group 3 attached in the lightning tank, the haze tank lid 6 is
The upper part of the pole column 1 is passed through the closed insertion hole 7 through the packing 8.

Next, attach the ○ ring 9 to the top of the pole post 1, and the counter spring washer 10, 1.
0. After inserting the washers 11 in sequence, insert the retaining ring 12 into the auxiliary fitting 13 to support it, and place it on the top of the pole post 1, as shown in FIG.

Next, the tip of the bolt 17 of the jig 14 is passed through the auxiliary metal fitting 13 and screwed into the connecting hole 4 for attaching the connection hole formed in the upper part of the pole post 1, so that the jig 14 is assembled as shown in FIG. Next, when the pressurizing block 16 of the jig 14 is rotated and lowered, the auxiliary metal fitting 13
enters into the concave groove 15 of the pressure block 16, and the stopper 12 supported by the auxiliary metal fitting 13 is pushed down by the lower surface of the pressure block 16, competing with the annular groove 5 formed on the tip side of the pole column 1. and fixed as shown in Fig. 4. In this case, by making the auxiliary metal fitting 13 a magnet, the adhesion to the pole pole 1 will be strengthened, and the shift of the center due to vibration can be prevented.
Workability can be further improved.

Further, in the above description, a jig in which a pressure block is screwed onto a bolt is shown, but a jig in which a piston or the like is used to move the pressure block up and down may also be used.

Furthermore, the method of the present invention can be applied not only to aircraft batteries and rocket batteries, but also to the assembly of large-capacity electric vehicle batteries. As explained above, according to the battery assembly method according to the present invention, the work is easy because it is carried out using auxiliary metal fittings and jigs, there is no damage to the electrode plates or separators, and the work time can be significantly shortened. It is easy to automate and has remarkable effects such as being able to reliably prevent liquid leakage.
