Description

Technical Field

[0001] The utility model relates to the technical field of spot welding of air conditioner side panels, in particular to a spot welding machine for processing air conditioner side panels with a protective structure. Background Art

[0002] The air conditioner side panel is the side protection panel installed on the air conditioner indoor unit. The air conditioner side panel needs to be processed using a spot welding machine during the production process. The spot welding machine is a mechanical equipment that uses the principle of double-sided double-point overcurrent welding. When working, two electrodes pressurize the workpiece so that the two layers of metal form a certain contact resistance under the pressure of the two electrodes, and when the welding current flows from one electrode through the other electrode, an instantaneous heat melt is formed at the two contact resistance points, and the welding current instantly flows from the other electrode along the two workpieces to this electrode to form a loop, and will not damage the internal structure of the welded workpiece.

[0003] However, the existing processing equipment has the following shortcomings:

[0004] Sparks will fly during the spot welding process, and the flying sparks will fall on the surface of the material plate, causing defects on the surface of the material plate. Due to the long-term welding of the equipment, the sparks generated by the welding will damage the protective plate, making it difficult for the protective plate to protect the material.

[0005] Therefore, we propose a spot welding machine for processing air conditioner side panels with a protective structure to solve the above-mentioned problems. Utility Model Content

[0008] Furthermore, a connecting block is fixedly connected to one end of the connecting arm away from the protective plate, and the connecting block is slidably connected to the surface of the limiting rod. By setting the protective plate, the surface of the material can be protected, thereby reducing the risk of sparks being generated during spot welding when the equipment is in use. The sparks are likely to fall on the surface of the material and cause material defects.

[0009] Furthermore, one end of the limiting rod away from the upper welding block is fixedly connected to the limiting block, and the connecting block and the upper surface of the limiting block are provided with the limiting rod to facilitate limiting the connecting block.

The first spring is provided to facilitate applying a reset elastic force to the connecting block.

[0011] Furthermore, a replacement device is provided on the surface of the protective plate, and the replacement device includes a positioning block and a connecting groove, the positioning block is fixedly connected to the upper surface of the protective plate, the connecting groove is provided with an interior of the positioning block, the connecting arm is clamped with the interior of the connecting groove, the upper surface of the positioning block is provided with a positioning groove, the interior of the connecting arm is provided with a pulling hole, the inner wall of the pulling hole is fixedly connected with a sliding rod, and the surface of the sliding rod is slidably connected with a connecting rod, and by providing the sliding rod, the connecting rod can be limited, thereby reducing the situation where the connecting rod is prone to deviation when the equipment is in use, making it difficult for the user to move the positioning rod smoothly.

[0012] Furthermore, one end of the connecting rod is fixedly connected to a positioning rod, and the positioning rod is engaged with the inside of the positioning groove. The positioning rod is provided to facilitate the connection between the connecting arm and the positioning block.

[0013] Furthermore, a second spring is sleeved on the surface of the sliding rod, and two ends of the second spring are fixedly connected to the surface of the connecting rod and the inner wall of the pulling hole respectively.

[0014] Compared with the prior art, the advantages and positive effects of the utility model are:

[0015] 1. In the utility model, when the equipment is in use, the user places the material to be welded on the upper surface of the lower welding block, and then starts the equipment to drive the upper welding block to move and perform spot welding on the surface of the material. When using the equipment, the user starts the equipment, the upper welding block contacts the lower welding block of the material for welding, and then the contact plate contacts the surface of the material, and then drives the protective plate to be flattened on the surface of the material, and the upper welding block continues to descend, driving the connecting block to move. When the connecting block moves, it drives the first spring to displace and deform to generate elastic force, and then the upper welding block is welded to the surface of the material, and the protective plate protects the sparks after welding.

[0026] Specifically, one end of the connecting arm 63 away from the protective plate 61 is fixedly connected with a connecting block 64 , and the connecting block 64 is slidably connected to the surface of the limiting rod 65 .

[0027] In this embodiment: by providing a protective plate 61, the surface of the material can be protected, reducing the risk of sparks being easily generated during spot welding when the equipment is in use, and the sparks easily falling on the surface of the material, causing material defects.

[0029] Specifically, the surface of the limiting rod 65 is sleeved with a first spring 66 , and the two ends of the first spring 66 are fixedly connected to the lower surface of the upper welding block 4 and the surface of the connecting block 64 , respectively. The first spring 66 is provided to facilitate the application of a reset elastic force to the connecting block 64 .

[0030] In this embodiment: a replacement device 7 is provided on the surface of the protective plate 61, and the replacement device 7 includes a positioning block 71 and a connecting groove 72.
