Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical processing, and more specifically, relates to a battery frame welding tool. Background Art

[0002] Automotive batteries are developing rapidly, but they also come with a series of safety risks. Automotive batteries include battery loads, connectors, protection circuits, frames, and other complex components installed within the frame. The battery frame must not only ensure the safety of the battery cells but also protect the battery from damage in extreme situations such as collisions. Therefore, the manufacturing of the battery frame has become particularly important.

[0003] Battery frame production is done by welding together heavy-duty aluminum alloy parts. Usually, the frame is made and welded to the bottom frame to form a box shape, and then the unit is assembled. During the welding process, the frame aluminum profile is easily deformed and twisted when welded using the ordinary welding table single-point fixing method, and it is impossible to determine whether the frame size is qualified.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a battery frame welding tool is provided to achieve a more practical purpose. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a battery frame welding tool to solve the problem that the frame aluminum profile is easily deformed and twisted during welding in the single-point fixing mode of the ordinary welding table, and it is impossible to determine whether the frame size is qualified.

[0006] The purpose and effect of the battery frame welding tool of the utility model are achieved by the following specific technical means:

[0007] A battery frame welding tool comprises a base, on which are provided four groups of fixing parts, and the four corners of the fixing parts are distributed to form corresponding battery frame accommodating grooves, the fixing parts comprising positioning angle blocks and surrounding frames arranged on the base, the side walls of the positioning angle blocks being right angles, the surrounding frames and the positioning angle blocks being separated to form a position for accommodating the battery frame, and fixing mechanisms being provided between the surrounding frames and the two side walls of the positioning angle blocks.

[0008] Furthermore, the fixing mechanism includes a fastening plate, which is L-shaped, and the two inner sides of the fastening plate correspond to the two sides of the positioning angle block respectively. The outer side of the fastening plate is rotatably connected to a screw, which passes through the frame and is threadedly connected to the frame. Clamps are installed on both inner side walls of the fastening plate.

[0009] Furthermore, both inner side walls of the fastening plate are provided with a sliding groove, a slider is provided for sliding in the sliding groove, the clamping block is connected to the slider, a movable cavity passing through the sliding groove is provided on the fastening plate, a limiting rod is provided on the slider, and the limiting rod passes through the movable cavity and is installed on the frame.

[0010] Furthermore, a protective pad is provided on the clamping block.

[0011] Furthermore, a guiding slanted top is provided on the top of the positioning angle block, and the guiding slanted top is arc-shaped, and an inner concave is provided on the outer side of the bottom of the positioning angle block.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] The fixings distributed at the four corners can pre-position the frame of the battery frame. After the frame is placed, it is surrounded by the enclosure. The fixing mechanism locks the frame between the enclosure and the positioning corner block. The four-corner fixing method increases stability, making it less likely to twist and deform during welding. At the same time, unqualified sizes cannot be placed in the pre-positioned fixings, and qualified products of size can be quickly judged. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] Example:

[0023] As attached Figure 1 To the attached Figure 3 As shown:

[0024] The utility model provides a battery frame welding tool, including a base 1, on which four sets of fixing parts are arranged, and the four corners of the fixing parts are distributed to form corresponding battery frame accommodating grooves, such as Figure 1 As shown, the fixing part matches the frame of the battery frame. The fixing part includes a positioning angle block 2 and a frame 3 provided on the base 1. The side wall of the positioning angle block 2 is a right angle. A position for accommodating the battery frame is separated from the frame 3 and the positioning angle block 2. Before welding, the frame can be pre-positioned in the corresponding position through the positioning angle block 2, so that the corner of the frame is located between the frame 3 and the positioning angle block 2, and the four-corner limiting method is more stable.

[0025] A guiding slant top 201 is provided on the top of the positioning corner block 2. The guiding slant top 201 is arc-shaped and can quickly guide the frame of the battery frame to slide into the corresponding position, making it smoother when placed. An inner recess 202 is provided on the outer side of the bottom of the positioning corner block 2. During welding, the edge of the frame does not contact the corner block 2, reducing the wear on the end face of the frame.

[0026] A fixing mechanism is provided between the frame 3 and the two side walls of the positioning angle block 2, including a fastening plate 4. The fastening plate 4 is L-shaped, and the two inner sides of the fastening plate 4 correspond to the two sides of the positioning angle block 2 respectively. The outer side of the fastening plate 4 is rotatably connected to a screw 401, which passes through the frame 3 and is threadedly connected to the frame 3. A knob 402 is provided at the end of the screw 401 to make it more convenient to rotate the screw 401. By rotating the screw 401, the fastening plate 4 can be moved closer to or away from the positioning angle block 2. When the battery frame frame to be welded is placed on the outside of the positioning angle block 2, the fastening plate 4 can fix the frame, and clamping blocks 5 are installed on both inner walls of the fastening plate 4. The frame is clamped and fixed by the clamping blocks 5 and the side walls of the positioning angle block 2, which can avoid the unevenness caused by different models of the frame affecting the clamping effect, and a protective pad 501 is provided on the clamping block 5. The protective pad 501 can be made of rubber, silicone or other materials, which increases friction and avoids damage to the frame.

[0027] In this embodiment, the clamping block 5 and the fastening plate 4 are not integrally arranged. Both inner side walls of the fastening plate 4 are provided with a sliding groove 403, and a slider 502 is provided in the sliding groove 403. The clamping block 5 is connected to the slider 502, and the clamping block 5 can slide horizontally in the sliding groove 403. The fastening plate 4 is provided with an active cavity 404 that passes through the sliding groove 403, and a limiting rod 503 is provided on the slider 502. The limiting rod 503 passes through the active cavity 404 and is arranged on the frame 3, so that the clamping block 5 can only be extended and retracted relative to a single side wall of the frame 3, and the clamping position of the clamping block 5 on the frame is fixed to avoid relative friction.

[0028] During the process of rotating the screw 401, the limiting rod 503 limits the clamping block 5 while also limiting the fastening plate 4 to prevent the fastening plate 4 from rotating and swinging. During the process of the fastening plate 4 approaching the positioning angle block 2, the clamping block 5 moves laterally relative to the fastening plate 4, while the clamping block 5 moves vertically closer to or farther away from the corresponding surface of the positioning angle block 2.

[0029] The embodiments of the present invention are provided for purposes of illustration and description and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for specific applications.
