[0023] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0024] Example 1

[0025] like Figure 1 — Figure 5 As shown, the present invention provides a welding fixture for assembling a door panel and a welding plate, comprising a bracket 100, an opening 110, a fixture plate 200, a positioning plate 210, a limiting surface 211, a pressure frame 120, a door panel 300, a welding plate 400, and a surrounding plate 310.

[0026] In this utility model, the opening 110 is rectangular, and the shape formed by the four surrounding plates 310 and the four welding plates 400 is rectangular. There is a notch 320 between two adjacent surrounding plates 310 for accommodating the welding plates 400.

[0027] The bracket 100 has an opening 110, and each of the four corners of the opening 110 has a tooling plate 200. Each tooling plate 200 has a positioning plate 210 at both ends, and each positioning plate 210 has a limiting surface 211. The two limiting surfaces 211 on the same tooling plate 200 intersect, specifically, the two limiting surfaces 211 on the same tooling plate 200 are perpendicular to each other. The door panel 300 is placed on the bracket 100, and the welding plate 400 is positioned on the tooling plate 200 and located between the two positioning plates 210. Multiple enclosures 310 within the door panel 300 communicate with their corresponding limiting surfaces 211. Through surface contact, the two sides of the welding plate 400 contact the ends of the adjacent surrounding plates 310. A pressure frame 120 is placed on the bracket 100. The door panel 300 is located between the bracket 100 and the pressure frame 120. When welding the door panel 300 to the welding plate 400, the door panel 300 needs to be placed on the bracket 100, and one end of the two adjacent surrounding plates 310 should be attached to the same tooling plate 200. Specifically, the ends of the two adjacent surrounding plates 310 that are close to each other should be attached to the two limiting surfaces 211 on the same tooling plate 200, respectively. Since the two limiting surfaces 211 on the same tooling plate 200 are perpendicular to each other, thus... This allows the door panel 300 to be positioned at that corner. Repeating this process completes the positioning of the door panel 300 at all four corners, thus positioning and installing the door panel 300 onto the bracket 100. This prevents the door panel 300 from moving left or right or back and forth relative to the bracket 100 during welding. Next, the pressure frame 120 needs to be pressed onto the bracket 100 to ensure the door panel 300 is stably pressed onto the bracket 100, preventing vertical movement between the door panel 300 and the welding plate 400 during welding. Finally, the welding plate 400 needs to be positioned and installed onto the four tooling plates 200. The welding plate 400 is inserted into the corresponding notch 320, ensuring that the two sides of the welding plate 400 are in contact with the ends of the adjacent partition 310, and the top edge of the welding plate 400 is in contact with the edge of the notch 320. Then, the welding plate 400 and the tooling plate 200 are clamped together by the F clamp. Then, the welding plate 400 is welded to the corresponding partition 310 by the welding process, and the top edge of the welding plate 400 is welded to the door panel 300. People can easily complete the welding of the welding plate 400 and the door panel 300. After the welding is completed, the F clamp is removed and the pressure frame 120 is removed, and the door panel 300 can be removed from the bracket 100.

[0028] The positioning plate 210 has a top surface 212 that connects to the bracket 100. The top surface 212 on the same positioning plate 210 is perpendicular to the limiting surface 211. The positioning plate 210 has a contact surface 213, which is located in the same vertical plane as the limiting surface 211. The positioning plate 210 also has a clearance groove 214 located between the contact surface 213 and the limiting surface 211. During installation, the surrounding plate 310 adjacent to the limiting surface 211 needs to be pressed against the limiting surface 211, ensuring surface contact between the surrounding plate 310 and the limiting surface 211. The two ends of the surrounding plate 310 are respectively aligned with the adjacent... After passing through the clearance groove 214, the two ends of the welding plate 400 need to be abutted against the corresponding contact surface 213, and the welding plate 400 and the contact surface 213 should be in surface contact. The two ends of the welding plate 400 abut against the ends of the adjacent surrounding plate 310, that is, the two ends of the welding plate 400 are also directly facing the adjacent clearance groove 214. Thus, when welding the welding plate 400 and the surrounding plate 310, the connection between the welding plate 400 and the surrounding plate 310 is located exactly at the clearance groove 214. In this way, the connection between the welding plate 400 and the surrounding plate 310 can be prevented from being welded together with the positioning plate 210, thereby ensuring that the welding plate 400 and the surrounding plate 310 can be successfully welded together.

[0029] Inclined surfaces 215 are provided between the top surface 212 and the contact surface 213, and between the top surface 212 and the limiting surface 211. When the door panel 300 is placed on the bracket 100, the enclosure panel 310 can move downward relative to the positioning plate 210 along the corresponding inclined surface 215, which plays a guiding role, so that the enclosure panel 310 can smoothly contact the corresponding limiting surface 211.

[0030] The tooling plate 200 has an arc-shaped plate 220 on the side facing the limiting surface 211. The arc-shaped plate 220 has at least two support blocks 221 for supporting the welding plate 400. The four corners of the opening 110 have abutment blocks 111 for supporting the top edge of the welding plate 400. The top edge of the welding plate 400 is an arc-shaped edge 410. When the welding plate 400 is placed in the corresponding notch 320, the bottom edge of the welding plate 400 needs to be placed on the support block 221 and the top edge of the welding plate 400 needs to be placed on the abutment block 111. This ensures that the abutment block 111 and the support block 221 can simultaneously support the bottom and top edges of the welding plate 400. During this process, it is necessary to ensure that both ends of the welding plate 400 abut against the surrounding plate 310, the inner surfaces of both ends of the welding plate 400 contact the corresponding contact surfaces 213, the top edge of the welding plate 400 abut against the edge of the notch 320, and that both ends of the welding plate 400 are flush with the ends of the adjacent surrounding plate 310, and that the top edge of the welding plate 400 is flush with the door panel 300. In this way, the welding plate 400 can be positioned and installed on the tooling plate 200.

[0031] The bracket 100 is provided with multiple lifting plates 130, each of which can be raised and lowered relative to the bracket 100. The bracket 100 is provided with lifting grooves 140 for accommodating the lifting plates 130. Inside the bracket 100, there are cylinders (not shown in the figure) for driving the lifting plates 130 to rise and fall. The number of cylinders is the same as the number of lifting plates 130. After the door panel 300 is welded to the welding plate 400, the pressure frame 120 needs to be removed. After that, people can operate each cylinder to work synchronously, so that the cylinder pushes the corresponding lifting plate 130 to move upward. At this time, the door panel 300 is exactly above each lifting plate 130 and in contact with each lifting plate 130. In this way, each lifting plate 130 can lift the door panel 300, thereby separating the door panel 300 from the bracket 100, so that people can easily pick up the door panel 300 from the bracket 100.

[0032] The bracket 100 is equipped with multiple reinforcing rods 150. By setting the reinforcing rods 150, the stability of the bracket 100 can be effectively improved, so that the bracket 100 can withstand greater forces.

[0033] Example 2

[0034] like Figure 6 As shown, the difference between this embodiment and embodiment one is that this embodiment adds a telescopic component 500 on the basis of embodiment one.

[0035] A fixed rod 160 is provided inside the opening of the bracket 100. A telescopic assembly 500 is provided on the fixed rod 160. One end of the telescopic assembly 500 is connected to the fixed rod 160 via a fixed plate 510. The telescopic assembly 500 includes a telescopic sleeve 520. A first telescopic rod 521 and a second telescopic rod 522 are respectively inserted into both ends of the telescopic sleeve 520. Both the first telescopic rod 521 and the second telescopic rod 522 are threadedly connected to the telescopic sleeve 520. The first telescopic rod 521 is connected to the fixed plate 510. A pressing plate 530 is provided on the end of the second telescopic rod 522 away from the telescopic sleeve 520. A pre-reserved gap 511 exists between the fixed plate 510 and the opening. Before placing the door panel on the bracket 100, the telescopic sleeve 520 and the second telescopic rod 522 must be screwed on to retract the first telescopic rod 521 and the second telescopic rod 522 into the telescopic sleeve 520, thereby expanding the pressing plate 530. When a door panel is placed on the support 100, one of the side panels needs to be inserted into the reserved gap 511, and the opposite side panel needs to be inserted between the pressing plate 530 and the support 100. Since the reserved gap 511 and the side panel have the same thickness, the side panel located in the reserved gap 511 will be clamped between the fixing plate 510 and the support 100. Then, the second telescopic rod 522 and the telescopic sleeve 520 are twisted in the opposite direction so that the pressing plate 530 and the adjacent side panel have a certain compressive force. At the same time, the compressive force will be transmitted to the first telescopic rod 521 and the fixing plate 510 in the form of a reaction force. The fixing plate 510 is made of metal material and has a certain plasticity and toughness. When the fixing plate 510 is subjected to the reaction force, the fixing plate 510 will squeeze the adjacent side panel. In this way, the two opposite side panels can be prevented from flipping inward to the opening during the welding process.

[0036] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0037] Furthermore, in this utility model, the use of terms such as "first," "second," and "a" is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0038] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0039] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.
