The locking assembly comprises a pushing cylinder 51, a first pressing block 52, a first roller 53, a limiting block 54, a second pressing block 55 and a second roller 56. The pushing cylinders 51 correspond to the lower electrode assemblies 2 one to one, and are disposed at the bottom of the base 1, and the output shafts thereof pass through the base 1 and are connected to the first pressing blocks 52. The first pressing block 52 is provided with a guide surface and a first inclined surface, the first inclined surface is matched with the first roller 53, the first roller 53 is rotatably arranged at the bottom of the guide seat through a roller mounting seat, and the guide surface is in sliding fit with the limiting block 54 to prevent the first pressing block 52 from shifting in the moving process. When the pushing cylinder 51 extends, the first pressing block 52 moves upwards along the limiting block 54 and is pressed against the first roller 53, so that the situation that the lower electrode tip 24 retreats outwards in the welding process is avoided. When the pushing cylinder 51 is reset, the first pressing block 52 is separated from the first roller 53, so that the inclined sliding pair can be ensured to be away from the shell 6 by the maximum stroke, interference between the bracket 64 on the shell 6 and the lower electrode tip 24 is avoided, and loading and unloading are facilitated.
The second pressing blocks 55 are multiple and correspond to the first pressing blocks 52, the second pressing blocks 55 are provided with second inclined surfaces and are arranged on the upper electrode holder 41, the second rollers 56 are rotatably arranged at the top of the guide holder through roller mounting seats, and when the upper electrode assembly 4 moves towards the lower electrode assembly 2, the second pressing blocks 55 are abutted and pressed against the second rollers 56 so as to be matched with the first rollers 53, so that the situation that the lower electrode tip 24 retreats outwards in the welding process is further avoided. Meanwhile, compared with the traditional scheme of clamping the lower electrode tip 24 through an air cylinder or an oil cylinder, the locking assembly can further improve the synchronism and concentricity of the three lower electrode tips 24 while avoiding the backward movement of the lower electrode tip 24, so that the shell 6 is uniformly stressed and is kept at the central shaft position.
The compressor shell is usually formed by buckling a main shell and a lower cover, so that when the compressor shell is subjected to resistance welding, the main shell and the lower cover need to be abutted, meanwhile, the main shell is electrically connected with a lower electrode, the lower cover is electrically connected with an upper electrode, and a contact surface of the lower cover and the main shell is heated and melted through a formed welding loop. To ensure the welding quality, while the lower electrode is in sufficient contact with the main case, a driving force is generally applied to the upper electrode to press the lower cover into the main case, thereby forming a wider welded joint surface.
Therefore, when the device is used, the main shell is sleeved outside the limiting part, and the bottom of the main shell is abutted against the supporting part. Then, the guide holder drives the lower electrode tip to the main casing body rapid movement and contact with the main casing body under the drive of the actuating cylinder, realizes the first step and compresses tightly, but the clamp force still is not enough this moment. Then, the pushing cylinder pushes the first pressing block to move upwards, the first pressing block moves upwards and is in rolling contact with the first roller, then the upper electrode assembly moves downwards, the second pressing block moves along with the upper electrode assembly and is in rolling contact with the second roller in the process, and therefore the guide seat is further locked, the guide seat is prevented from moving reversely in the welding process, and it is guaranteed that the lower electrode tip and the main shell body have enough welding surfaces and are in good contact.
When the upper electrode tip drives the lower cover to move towards the main casing body and push the whole downward movement of compressor casing, the main casing body bottom pushes the part backup pad earlier and moves, conflict with the layer board until the main casing body bottom, then the main casing body promotes the relative guide holder downstream of centre gripping slider through the layer board, because the glide plane is the inclined plane, consequently, the lower electrode tip further gathers together to the main casing body, realize that the second step compresses tightly, the clamp force obtains great promotion, prevent that the relative lower electrode tip of the main casing body from shifting. At the moment, the supporting plate moves downwards and is pressed against the supporting plate of the supporting plate, and the force-releasing spring can bear part of the pressure of the upper electrode according to the setting, so that the deformation caused by overlarge circumferential pressure of the main shell is prevented.
After welding is completed, the upper electrode assembly resets, the second pressing block is far away from the second roller, the resetting piece resets by pulling the supporting plate or the clamping sliding block, the pushing cylinder is started to enable the first pressing block to be far away from the first roller, the guide seat quickly resets under the action of the driving cylinder and is far away from the whole shell, the clamping force of the device can be quickly removed, and the whole shell is taken out to complete a welding period.
According to the clamping type electrode structure, the upper electrode head is used for carrying out pressure welding on a part to be welded, and meanwhile, the clamping force of the lower electrode on the part to be welded is improved twice by driving the clamping slide block to move obliquely, so that the clamping force is greatly improved. And locking is carried out through the locking device, so that the lower electrode tip is ensured to be in good contact with the part to be welded, the synchronism and the concentricity of the clamping action are improved, the part to be welded is stressed uniformly and has higher coaxiality, and the welding quality is improved.
