Description

Technical Field

[0001] This utility model relates to the field of welding equipment technology, and in particular to a welding device for a refrigerator lower beam connecting block. Background Technology

[0002] The refrigerator's lower beam is a long, strip-shaped support structure that connects the two sides of the refrigerator, ensuring its stability and safety. The section where the lower beam connects to the refrigerator via bolts is thin. To ensure the connection's strength and extend its lifespan, a connecting block is welded to this connection point. After the lower beam is bolted to the refrigerator, the bolts hold the connecting block in place, rather than directly supporting the thinner section of the lower beam, thus providing effective protection. However, currently, when welding the connecting block onto the lower beam, it's difficult to secure it properly. The connecting block can easily slide on the lower beam, causing it to be misaligned after welding. This results in incomplete welding, requiring disassembly and re-welding, a cumbersome process that reduces the efficiency of welding the lower beam to the connecting block. Utility Model Content

[0003] This utility model discloses a welding device for the connecting block of the lower beam of a refrigerator, which solves the problem that the connecting block can easily slide on the lower beam, causing the connecting block to be skewed after welding on the lower beam, and requiring the connecting block to be disassembled and reworked.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A refrigerator lower beam connecting block welding device includes a housing and a connecting block. A bearing block is fixed on the housing, and a worktable is provided above the bearing block. One side of the worktable has a notch for inserting the lower beam. A baffle is fixed on the worktable to block the top of the notch. The side of the baffle near the notch has an opening for inserting the connecting block. The housing is provided with a fixed electrode and a downwardly movable electrode, and the opening is located between the fixed electrode and the movable electrode.

[0006] Compared with the prior art, the present invention has the following beneficial effects:

[0007] Workers can insert the lower beam into the notch to position it, ensuring that the top of the lower beam contacts the bottom surface of the baffle and the top of the stationary electrode contacts the bottom of the lower beam, thus completing the positioning of the material. Then, the connecting block is placed into the opening, confined within it and contacting the top of the lower beam, thus limiting its position. Subsequently, the moving electrode moves downwards and contacts the connecting block, completing the welding and fixing of the connecting block and the lower beam. This invention effectively limits the positioning of the lower beam and connecting block, preventing displacement of the connecting block after it is placed on the lower beam, ensuring precise welding of the connecting block to the designated location on the lower beam. The operation is simple and fast, improving the welding efficiency of the lower beam and connecting block. Attached Figure Description

[0013] The specific content of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0014] like Figure 1 , Figure 2 and Figure 4As shown, this utility model provides a welding device for a refrigerator lower beam connecting block, including a housing 1 and a connecting block 8. A bearing block 2 is fixed on the housing 1, and a workbench 3 is provided above the bearing block 2. A notch 31 for inserting the lower beam is opened on one side of the workbench 3. A baffle 32 is fixed on the workbench 3 to block the top of the notch 31. An opening 33 for inserting the connecting block 8 is opened on the side of the baffle 32 near the notch 31. A fixed electrode 21 and a downwardly movable electrode 5 are provided on the housing 1, and the opening 33 is located between the fixed electrode 21 and the movable electrode 5. After inserting one end of the lower beam into the notch 31, the end of the lower beam contacts the side of the notch 31 closest to the chassis 1, and both sides of the lower beam contact the sides of the notch 31 respectively. Simultaneously, the top and bottom of the lower beam contact the bottom of the baffle 32 and the top of the stationary electrode 21 respectively, completing the positioning of the lower beam and aligning the part of the lower beam to be welded with the opening 33. Then, the operator places the connecting block 8 on top of the lower beam and pushes it towards the opening 33, allowing it to enter the opening 33 and contact the inner wall, completing the positioning of the connecting block 8. Subsequently, the moving electrode 5 moves downwards to contact the middle of the connecting block 8, and the smaller slots on the connecting block 8 (such as...) are then... Figure 4 After the cover is covered, the welding operation of the connecting block 8 and the lower beam is completed with the fixed electrode 21. The two semi-annular grooves on the connecting block 8 correspond to the two bolt holes on the lower beam respectively. The chassis 1 is the chassis of the current spot welding machine.

[0015] like Figure 1 and Figure 3 As shown, a collection frame 7 is fixed to one side of the chassis 1, and a connecting plate 71 is fixed inside the collection frame 7. A set of slots is opened on the top of the connecting plate 71. A magnet 72 that contacts the connecting block 8 is fixedly embedded in the bottom of the collection frame 7. The operator can insert the connecting block 8 into the slot on the connecting plate 71 to neatly place the connecting block 8, so that the operator can pick up the connecting block 8 later. There are two sets of connecting plates 71, and each set of connecting plates 71 has two connecting plates 71. The two connecting plates 71 are symmetrically distributed and are used to fix several connecting blocks 8 at the same time through their own set of slots. The magnet 72 can generate a small suction force to attract the connecting block 8, increasing the stability of the connecting block 8 placed in the slot of the connecting plate 71. There are two magnets 72, and the two magnets 72 are located below the two sets of connecting plates 71 respectively.

[0016] like Figure 1As shown, a rubber pad 35 is fixed to one side of the notch 31; a support column is fixed between the workbench 3 and the bearing block 2. Since the part of the lower beam inserted into the notch 31 is relatively thin, after the lower beam is inserted into the notch 31, one end of the lower beam will contact the rubber pad 35, which can effectively protect the end of the lower beam and prevent damage or bending of the end of the lower beam due to excessive force by the operator; the rubber pad 35 is fixed to the side of the notch 31 near the chassis 1, and the support column can fix the workbench 3 above the bearing block 2.

[0017] like Figure 1 and Figure 2 As shown, a screw 36 is fixed to one side of the workbench 3. An L-shaped pad 4 is fitted onto the screw 36. The end of the pad 4 away from the screw 36 is located inside the notch 31. A nut 37 is threaded onto the screw 36 and contacts the pad 4. Depending on the width of the lower beam, a pad 4 of corresponding thickness can be fixed to the screw 36 using the nut 37, so that one end of the pad 4 is located inside the notch 31. Subsequently, after the lower beam is inserted into the notch 31, one side of the lower beam contacts the side of the notch 31 away from the pad 4, and the other side of the lower beam contacts the portion of the pad 4 located inside the notch 31, thus completing the positioning of the lower beam.

[0018] like Figure 1 As shown, the housing 1 is equipped with a hydraulic rod 6, and a fixed block 61 connected to the housing 1 is fixed to the hydraulic rod 6. A lifting block 62 connected to the moving electrode 5 is fixed to the telescopic end of the hydraulic rod 6. The fixed electrode 21 is fixed on the bearing block 2, located below the opening 33, and the moving electrode 5 is located above the opening 33. After the hydraulic rod 6 is activated, the moving electrode 5 can be driven to move downward or upward through the lifting block 62 to complete the welding operation of the connecting block 8 and the lower beam.

[0019] like Figure 1 and Figure 2 As shown, a magnetic block 34 is embedded inside the opening 33. When the connecting block 8 is placed inside the opening 33 and comes into contact with the magnetic block 34, the magnetic block 34 can hold the connecting block 8 in place, increasing the stability of the connecting block 8 and preventing the connecting block 8 from moving out of the opening 33.

[0020] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
