Description

Technical Field

[0001] This utility model relates to the field of welding fixtures, and in particular to a welding fixture for the bottom plate of an energy storage box. Background Technology

[0002] The energy storage tank bottom plate is a part formed by bending a sheet metal part into a prototype, and then welding a corner plate to the bent part. The corner plate is an arc-shaped plate with an angle of only 90°. The welding position is at the arc corner of the prototype. During welding, the arc side of the corner plate needs to be tightly pressed against the arc corner of the prototype, and the surface of the corner plate must be perpendicular to the circumference of the arc corner. Because the corner plate and the prototype are in arc contact, if the operator holds the corner plate by hand during welding, the corner plate is prone to tilting, meaning that the surface of the corner plate is difficult to maintain in a state perpendicular to the circumference of the arc corner, affecting the welding quality. Therefore, a welding fixture is needed to ensure the welding quality of the energy storage tank bottom plate. Utility Model Content

[0003] The purpose of this utility model is to provide a welding fixture for the bottom plate of an energy storage box, which addresses the above-mentioned problems, so that the surface of the corner plate is always kept in a state perpendicular to the circumferential surface of the arc corner during the entire welding process, thereby ensuring the welding quality of the bottom plate of the energy storage box.

[0004] The technical solution adopted in this utility model is as follows: A welding fixture for the bottom plate of an energy storage tank includes a base, on which a first constraint member and a second constraint member are detachably connected. The first constraint member has a constraint groove, the width of which matches the length of the prototype part. The bottom and side surfaces of the constraint groove are perpendicular to the surface of the base. The second constraint member is located inside the constraint groove and has a constraint plate. After the first and second constraint members are installed, the distance between the constraint plate and the bottom of the constraint groove is the thickness of the sheet metal part used to manufacture the bottom plate of the energy storage tank. The second constraint member has limiting edges on both sides. The length direction of the limiting edges is parallel to the depth direction of the constraint groove, and the distance from the limiting edge to the side of the constraint groove satisfies the following condition: After installing the prototype and the corner plate, one straight edge of the corner plate fits into the limiting edge, the curved edge of the corner plate fits into the inner side of the rounded corner on the prototype, and the outer side of the prototype fits into the side of the constraint groove.

[0005] Furthermore, the surface of the constraint plate is perpendicular to the surface of the base.

[0006] Furthermore, the second constraint member has a second bonding plate that fits against the surface of the base, and the surface of the constraint plate is perpendicular to the surface of the second bonding plate.

[0007] Furthermore, the second bonding plate is provided with a second through hole, and the base is provided with a second threaded hole that matches the position of the second through hole. A screw passes through the second through hole and is threadedly connected to the second threaded hole to realize the detachable connection between the second constraint member and the base.

[0008] Furthermore, the first constraint member has a first bonding plate that fits against the surface of the base, and the bottom surface and the side surface of the constraint groove are both perpendicular to the surface of the first bonding plate.

[0009] Furthermore, the first bonding plate is provided with a first through hole, and the base is provided with a first threaded hole that matches the position of the first through hole. A screw passes through the first through hole and is threadedly connected to the first threaded hole to realize the detachable connection between the first constraint member and the base.

[0010] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: This utility model constrains the prototype component with a first constraint and a second constraint, allowing the prototype component to be installed in a position perpendicular to the base surface. The corner plate is constrained by the limiting edge of the second constraint and placed on the base surface, so that the surface of the corner plate always remains in a state perpendicular to the circumferential surface of the arc corner, and the arc side of the corner plate can always keep in contact with the inner side of the arc corner; thereby ensuring the welding quality of the energy storage box bottom plate.

Detailed Implementation

[0012] In the description of this specification, it should be noted that if terms such as "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," or "outer" appear to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product is in use, they are only for the convenience of describing this specification and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this specification.

[0013] Furthermore, the use of terms such as "horizontal" or "vertical" in this specification does not imply that the component must be absolutely horizontal or suspended, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0014] In the description of this specification, it should also be noted that, unless otherwise expressly specified and limited, the terms “set up,” “install,” “connect,” and “link” should be interpreted broadly. For example, a link can be a fixed link, a detachable link, or an integral link; it can be a mechanical link or an electrical link; it can be a direct link or an indirect link through an intermediate medium; it can be a connection within two components.

[0015] like Figures 1-3 As shown, a welding fixture for an energy storage tank bottom plate includes a base 1. A first constraint member 3 and a second constraint member 2 are detachably connected to the base 1. The first constraint member 3 has a constraint groove 31, the width of which matches the length of a prototype part 4. The bottom and side surfaces of the constraint groove 31 are perpendicular to the surface of the base 1. The second constraint member 2 is located within the constraint groove 31 and has a constraint plate 24. After the first constraint member 3 and the second constraint member 2 are installed, the distance between the constraint plate 24 and the bottom of the constraint groove 31 is equal to the thickness of the sheet metal part used to manufacture the energy storage tank bottom plate. The second constraint member 2 has limiting edges 23 on both sides. The length direction of the limiting edges 23 is parallel to the depth direction of the constraint groove 31, and the distance from the limiting edges 23 to the side of the constraint groove 31 satisfies the following condition: After installing the prototype 4 and the corner plate 5, one straight edge of the corner plate 5 is attached to the limiting edge 23, the arc edge of the corner plate 5 is attached to the inner side of the arc corner 41 on the prototype 4, and the outer side of the prototype 4 is attached to the side of the constraint groove 31.

[0016] In this embodiment, the second constraint member 2 supports the prototype member 4 against the constraint groove 31, so that the outer side of the prototype member 4 is in close contact with the side and bottom of the constraint groove 31. Therefore, the technical feature that "the bottom surface and the side surface of the constraint groove 31 are both perpendicular to the surface of the base 1" is restricted. The purpose is to ensure that the prototype member 4 can be installed in an attitude perpendicular to the surface of the base 1, thereby providing a basis for the subsequent corner plate 5 to always maintain the circumferential surface perpendicular to the arc corner 41.

[0017] In this embodiment, the prototype 4 is constrained by the first constraint member 3 and the second constraint member 2, so that the prototype 4 is installed in a posture perpendicular to the surface of the base 1. The corner plate 5 is constrained by the limiting edge 23 of the second constraint member 2. The corner plate 5 is placed on the surface of the base 1, so that the surface of the corner plate 5 is always kept in a state perpendicular to the circumferential surface of the arc corner 41, and the arc side of the corner plate 5 can always keep in contact with the inner side of the arc corner 41; thereby ensuring the welding quality of the energy storage box bottom plate.

[0018] In one feasible implementation, the surface of the constraint plate 24 is perpendicular to the surface of the base 1, which further improves the stability of the prototype 4 when it is installed in a posture perpendicular to the surface of the base 1. That is, the bottom sheet metal of the prototype 4 is clamped by the constraint plate 24 and the constraint groove 31 to constrain the prototype 4.

[0019] In one feasible implementation, the second constraint member 2 has a second bonding plate 21 that is in contact with the surface of the base 1, and the surface of the constraint plate 24 is perpendicular to the surface of the second bonding plate 21. Since the surface of the base 1 is part of the structure of the base 1 and the constraint plate 24 is part of the structure of the second constraint member 2, the base 1 cannot be used as a reference when processing the second constraint member 2. Therefore, the second bonding plate 21 that is in contact with the surface of the base 1 is determined, and the constraint plate 24 can be processed with the second bonding plate 21 as a reference, thereby completing the manufacturing of the second constraint member 2 that achieves "the surface of the constraint plate 24 is perpendicular to the surface of the base 1".

[0020] In one feasible implementation, the second bonding plate 21 is provided with a second through hole 22, and the base 1 is provided with a second threaded hole that matches the position of the second through hole 22. A screw passes through the second through hole 22 and is threadedly connected to the second threaded hole to achieve a detachable connection between the second constraint member 2 and the base 1. By using a detachable connection to install the second constraint member 2, the operation of installing the prototype member 4 and removing the already welded energy storage box bottom plate is more convenient. This avoids the prototype member 4 being forcibly inserted into the installation position (the gap between the first constraint member 3 and the second constraint member 2), and also avoids the energy storage box bottom plate being forcibly removed after welding, thereby avoiding surface scratches on the energy storage box bottom plate.

[0021] In one feasible implementation, the first constraint member 3 has a first bonding plate 32 that fits against the surface of the base 1, and the bottom surface and the side surface of the constraint groove 31 are perpendicular to the surface of the first bonding plate 32; similar to the second constraint member 2, this is for the purpose of facilitating processing and manufacturing.

[0022] Furthermore, the first bonding plate 32 is provided with a first through hole 33, and the base 1 is provided with a first threaded hole that matches the position of the first through hole 33. A screw passes through the first through hole 33 and is threadedly connected to the first threaded hole to realize the detachable connection between the first constraint member 3 and the base 1. The installation of the first constraint member 3 by means of detachable connection is the same as the installation of the second constraint member 2 by means of detachable connection, both of which are for the convenience of installing the prototype member 4 and removing the already welded energy storage box bottom plate.

[0023] This invention is not limited to the specific embodiments described above. This invention extends to any new feature or combination disclosed in this specification, as well as any new method or process step or combination disclosed herein.
