Description

Technical Field

[0001] This utility model belongs to the field of battery technology, specifically relating to a tooling for bolt connection of aviation plugs for storage batteries. Background Technology

[0002] Lead-acid batteries are typically connected to external wiring via terminal blocks or copper cores. Some batteries require specialized aviation connectors. These connectors have a standard design and need to be securely attached to the battery casing. Installation locations for the aviation connectors are usually pre-drilled on the battery exterior. The connectors are typically secured to the battery casing with bolts and nuts. However, due to battery size and installation space limitations, the available space for these connectors is often limited, making tooling or manual operation inconvenient.

[0003] In practice, precise alignment of bolts and nuts is crucial when installing them. Due to the limited operating space around the battery casing, standard wrenches are difficult to use, especially when several mounting holes are parallel or side-by-side. Manual operation is also inconvenient; aligning and tightening the holes is quite challenging.

[0004] Therefore, how to provide a tooling for assisting in the connection of aviation plug bolts to the battery housing is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of this, the present invention provides a tooling for connecting aviation plug bolts to storage batteries, which can conveniently connect aviation plug bolts to the storage battery housing and is easy to operate.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a tooling for bolt connection of a storage battery aviation plug, comprising:

[0007] An insulating plate has an arc-shaped notch on one side to avoid the stage of the aviation plug. The insulating plate has multiple nut limiting grooves on both sides corresponding to the arc-shaped notch. The bottom of the nut limiting groove has a threaded through hole that passes through the insulating plate. The layout of the nut limiting groove corresponds to the layout of the bolt holes on the battery housing for installing the aviation plug.

[0008] The positioning block is integrally formed on the other side of the insulating plate. The positioning block overlaps the battery housing and is used to center-align the positions of the nut limiting groove, screw through hole and bolt hole.

[0009] The beneficial technical effects of this utility model are as follows: Due to the structural limitations of the battery casing, it is inconvenient to align and tighten the nuts when connecting the aviation plug bolts. The nuts can be pre-installed by the nut limiting groove on the insulating plate. In addition, the layout of the nut limiting groove corresponds to the layout of the bolt holes on the battery casing used to install the aviation plug. During installation, it is only necessary to align the bolt limiting groove and the bolt hole. This facilitates the assembly of the bolts and nuts on the aviation plug. The added positioning block is used to center-align the positions of the nut limiting groove, the screw through hole and the bolt hole, which facilitates the connection of the bolt and nut. In addition, the limiting effect of the nut limiting groove on the nut can also make it faster to rotate the bolt to complete the tightening work. After the nut is assembled, the insulating plate can be removed.

[0010] Preferably, the nut limiting groove is a polygonal groove, and the groove depth is consistent with the thickness of the nut.

[0011] The resulting technical effect is that, in specific implementation, the polygonal groove needs to be adapted to the shape of the nut, such as a hexagonal groove, and the depth of the nut's limiting groove is consistent with the nut's thickness, which facilitates the fit between the insulating plate, the nut, and the shell, and makes subsequent alignment and assembly easier.

[0012] Preferably, the inner diameter of the screw hole is smaller than the inner diameter of the inscribed circle of the nut limiting groove, and the diameter of the screw hole is larger than the outer diameter of the screw for mounting the aviation plug.

[0013] The resulting technical effect is that the screw hole provides a basis for tightening the nut. In addition, the screw hole is small, which forms a step with the nut retaining groove, making it easier to insert the nut.

[0014] Preferably, the battery housing has a mounting position for installing an aviation plug, the top of the battery housing corresponding to the mounting position is provided with a top edge, the insulating plate is attached to the inner side of the battery housing corresponding to the mounting position, and the positioning block is attached to the top edge of the housing.

[0015] The resulting technical effect is that the mounting position on the battery casing provides a location for assembling the aviation plug, and the top edge cooperates with the positioning block to position the insulating plate. In specific implementation, the bottom of the insulating plate contacts the upper surface (bending groove of the casing) of the mounting position of the casing, and is flush with it to assist in positioning.

[0016] Preferably, the distance from the screw hole and the nut limiting groove to the top edge is the same as the distance from the bolt hole to the top edge.

[0017] The resulting technical effect is that, in specific implementation, the distance from the center of the screw hole and the center of the nut limiting groove to the top edge is consistent with the distance from the center of the bolt hole to the top edge. This is a prerequisite for ensuring that the screw hole, nut limiting groove, and bolt hole are concentric after the insulating plate is positioned, and it also facilitates the subsequent connection of bolts and nuts.

[0018] Preferably, the arc-shaped notch is U-shaped and partially surrounds the outer side of the aviation plug stage.

[0019] The resulting technical effect is that, due to the structural characteristics of the aviation plug, the arc-shaped notch on the insulating plate will not affect the installation process of the aviation plug. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] See appendix to this utility model Figures 1 to 5 According to an embodiment of the present invention, a tooling for bolt connection of an aviation plug for a storage battery includes:

[0028] An insulating plate 1 has an arc-shaped notch 2 on one side end to avoid the aviation plug stage 51. The insulating plate 1 and the two sides corresponding to the arc-shaped notch 2 are provided with multiple nut limiting grooves 3. The bottom of the nut limiting groove 3 is coaxially provided with a screw through hole 4 that passes through the insulating plate 1. The layout of the nut limiting groove 3 corresponds to the layout of the bolt holes 8 on the battery housing 6 for installing the aviation plug.

[0029] Positioning block 7 is integrally formed on the other end of the insulating plate 1. Positioning block 7 overlaps the battery housing 6 and is used to center-align the positions of the nut limiting groove 3, the screw through hole 4 and the bolt hole 8.

[0030] In other embodiments, the nut limiting groove 3 is a polygonal groove, which needs to match the nut during use. For example, a hexagonal nut requires a hexagonal nut limiting groove, and the groove depth of the nut limiting groove 3 is consistent with the thickness of the nut 9.

[0031] In some other specific embodiments, the inner diameter of the screw through hole 4 is smaller than the inner diameter of the inscribed circle of the nut limiting groove 3, which can form a step to facilitate the assembly of the locking nut. The diameter of the screw through hole 4 is larger than the outer diameter of the screw for installing the aviation plug, ensuring that the screw can pass through smoothly, which can also be understood as the nut being tightened smoothly.

[0032] In some other embodiments, the battery housing 6 has a mounting position 61 for mounting the aviation plug 5, and the top of the battery housing 6 corresponding to the mounting position is provided with a top edge 62. The insulating plate 1 is attached to the inner side of the battery housing corresponding to the mounting position, and the positioning block 7 is attached to the top edge 62 of the housing.

[0033] In some other specific embodiments, the distance from the center of the screw hole 4 and the nut limiting groove 3 to the top edge 62 is consistent with the distance from the center of the bolt hole 8 to the top edge, which can ensure that the centers of the screw hole, bolt hole and nut limiting groove are aligned in the future.

[0034] Specifically, the arc-shaped notch 2 is U-shaped and partially surrounds the outside of the aviation plug stage. The use of this device will not interfere with the aviation plug, and therefore will not affect the installation of the aviation plug.

[0035] When using, first install the nut into the nut limiting groove, then attach the insulating plate to the bolt-hole side of the housing, and install the aviation plug into the mounting position on the housing. The arc-shaped notch on the insulating plate can avoid the stage of the aviation plug. At this time, the positioning block is attached to the top edge of the housing cover.

[0036] At this point, the four fastening bolt mounting holes of the aviation plug, the bolt holes on the housing, and the nuts installed on the tooling are all aligned in a straight line.

[0037] Insert the fastening bolt (screw) to be connected into the mounting hole on the aviation plug. The bolt contacts the nut on the fixture. Use a screwdriver of the corresponding type to tighten the bolt into place, and then back out of the fixture.

[0038] This product simplifies the installation process of securing aviation connectors to the battery casing using bolts and nuts. Compared to existing technologies, it eliminates the inconvenience of manual installation, reduces workload, and allows for bolt installation even in limited operating spaces, making the operation quick and easy.

[0039] The apparatus and methods disclosed in the embodiments are described simply because they correspond to the methods disclosed in the embodiments. For relevant details, please refer to the method section.

[0040] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
