Description

[Detailed description of the invention] Industrial applications The present invention relates to a method for assembling an automobile battery.

BACKGROUND ART As is well known, an automobile battery is constructed by placing a tray made of liquid-resistant synthetic resin on a battery mount bracket that is connected to the battery installation part of the vehicle body, placing the battery on this tray, and placing the battery in pairs on the left and right sides. The hook part provided at one end of the stay rod is engaged with the engagement hole provided in the battery mount bracket or the battery installation part of the vehicle body, and the screw part provided at the other end of the stay rod is placed on the battery. Penetrates through the screw insertion holes provided at both ends of the plate,
Fasten a nut to the part of this threaded part that protrudes above the stopper plate, and connect the stay rod, stopper plate,
It is assembled to a battery mount bracket that is integrated with the single battery installation section by the cooperation of nuts and the like.

Problems to be Solved by the Invention The hook part of the stay rod is formed by folding the end of the stay rod into a substantially U-shape, and the engaging hole part is formed in the battery installation part of the vehicle body or in the battery mount integrated therein. installed on the bracket. Therefore, when assembling the battery, insert the threaded part of the stay rod into the engagement hole from below the vehicle body, move the stay rod upward, and then
Since it is difficult to lock the hook part in the engagement hole, the stay rod is turned over from above the vehicle body while the hook part is locked in the engagement hole. Therefore, when attempting to automatically assemble the battery using a robot, the movement of the arm of the robot when locking the hook portion into the engagement hole becomes complicated, making it difficult to control the operation of the robot. Therefore, the battery is assembled manually, which requires a great deal of time and effort.

SUMMARY OF THE INVENTION Accordingly, the present invention provides a method for assembling a battery for an automobile, which allows automatic battery assembly to be easily performed.

Means for Solving the Problems The battery placement part of the car body and the battery mount bracket are divided, and the battery placement part and the battery mount bracket of the car body are provided with a positioning means consisting of a locating pin and a locating hole, and a mounting hole portion, respectively. The battery is integrally assembled to the battery mount bracket by a fastening means, and the battery mount bracket is positioned and placed from above the battery mounting portion by fitting the locating pin and the locating hole. With,
Connect with bolts through the mounting holes.

Example Embodiments of the present invention will be described based on the drawings.

As shown in FIGS. 1 to 3, the battery mount bracket 1 is separated from the battery installation part 2 of the vehicle body. This battery mount bracket 1 has a rim 1a standing upright on its periphery, and has a rectangular shape that receives the lower part of a battery 4 via a tray 3 made of liquid-resistant synthetic resin. This battery mount bracket 1 and the battery installation part 2 of the vehicle body are provided with a positioning means 7 consisting of a locating pin 5 and a locating hole 6, and a mounting hole $8.9, respectively, in either the front/rear or left/right direction. It is set up facing each other. Specifically, two flanges 10 are horizontally protruded outward from one set of the front and rear edges or the left and right edges of the battery mount bracket 1. A locate hole 6 penetrating vertically is formed in each of the two flanges 10 at approximately the center thereof.

On each side of the locating hole 6 of the flange 10,
A screw insertion hole passing through in the vertical direction is formed as the mounting hole portion 8 . Also, a locate pin 5 is provided upwardly projecting from each portion of the battery placement portion 2 corresponding to the locate hole 6. A screw hole is formed in each portion of the battery installation portion 2 corresponding to the screw insertion hole 8 as a mounting hole portion 9 formed by joining a weld nut to the back surface of the desk. 11 indicates a tying means, which includes a stopper plate and 2.
Book stay rod 13, two engagement holes 14 and nut 1
It consists of 5. When the stopper plate 12 is disposed on the battery 4, the stopper plate 12 is provided with an insertion hole 12a at each of both ends that protrude outward from the battery 4.

Each of the two stay rods 13 has a substantially U-shaped hook portion 13a at one end, and a screw fls13t at the other end. Each of the two engagement holes 14 is horizontally protruded outward from a pair of edges that do not form the flange 10 of the battery mount bracket 1, and is provided with an insertion hole 16 that passes through the battery mount bracket 1 in the vertical direction. .

In the above embodiment structure, in order to assemble the battery 4 to the battery installation part 2 of the vehicle body, the battery mount bracket 1, which has the locating hole 6, the screw insertion hole 8 (mounting hole part), and the engaging hole part 14, is assembled. Place the tray 3, place the battery 4 on the tray 3, and insert the threaded portions 13b of the two steel rods 13 from below the engagement hole 14 into the insertion hole 1.
6, and move the two stay rods 13 upward as they are, positioning the upwardly facing ends of the hook portions 13a to the outside of the engagement holes 14, and then inserting the hook portions 13a The screws B13 of the two stay rods 13 are inserted into the screw insertion holes I2a at both ends of the stopper plate 120 by lowering the stopper plate 12 from above the two stay rods 13.
b is penetrated, the stopper plate 12 is placed on the battery 4, and a nut 1 is attached to the tip of the threaded portion 13b of the stay rod 13 that protrudes above the stopper plate 12.
5 are M-connected, the battery 4 is integrally assembled onto the battery mount bracket 1 with the tray 3 sandwiched therebetween by the fastening means 11. Then, lower this battery mount bracket 1 toward the battery mounting bracket 8 (12) of the vehicle body, fit the locating hole 6 into the locating pin 5,
The battery mount bracket 1 is placed on the battery placement part 2 while being positioned by this fitting, and the bolt 17 is fastened from the screw insertion hole 8 to the screw hole 9 from above.

As a result, the battery mount bracket 1 is coupled to the battery installation portion 2 via the screw insertion hole 8 and the screw hole 9 with bolts.

Effects of the Invention As described above, according to the present invention, the battery mount bracket, on which the battery is integrally assembled by the fastening means, is placed on the battery installation portion of the vehicle body from above via the positioning means, and is coupled with bolts. Therefore, by moving the robot's arm in one direction, up and down, the battery can be automatically assembled to the vehicle body. Moreover, even if a U-shaped steel rod is used at one end of the fastening means, since the battery is integrally assembled to the battery mount bracket that is separated from the single battery installation part, the engagement hole provided in the battery mount bracket is The stay rod can be inserted from the other end into the screw insertion hole in the section, and by simply moving the robot's arm in one direction, for example up or down,
The hook portion can be locked in the engagement hole. As a result, there is a novel effect in that automatic assembly of the battery to the battery mount bracket can be easily performed.
