Technical Field

[0001] This utility model relates to the field of auxiliary reversing for welding, specifically an auxiliary tooling for shell processing. Background Technology

[0002] The inverter housing is made of either plastic or metal. The plastic housing is made by injection molding, while the metal housing is made by bending metal sheets into various parts and then welding them together.

[0003] In the existing technology, when welding the various components of the inverter housing made of sheet metal, the workers need to constantly adjust the welding angle according to the welding position. In order to ensure the stability of the welding, a welding limit device is set to limit the position of the housing body during welding, so it is not convenient to adjust the angle of the housing body.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1-3In this embodiment of the utility model, an auxiliary tooling for processing shells includes a worktable 1, a rotating disk 2 is provided on the top of the worktable 1, and a downwardly protruding rotating shaft 5 is integrally formed at the center of the bottom end of the rotating disk 2. The worktable 1 and the rotating shaft 5 are rotatably connected by bearings. A rubber layer is adhered to both the bottom end and the top end of the rotating disk 2. An adsorption mechanism is provided inside the rotating disk 2, which penetrates the rotating shaft 5 and extends to the bottom of the rotating shaft 5. A resistance mechanism is installed at the bottom end of the worktable 1, which penetrates to the top of the worktable 1 and is located on one side of the adsorption mechanism.

[0019] In this embodiment: First, when assembling and welding the bent shell parts, the bent shell body is placed on the rotating disk 2, and then the adsorption mechanism is activated. At this time, the position of the shell body is fixed under the adsorption force. The resistance mechanism, which is in the reset state, limits the position of the rotating disk 2. When adjusting the welding position and angle, a downward pressure is applied to the resistance mechanism. At this time, the resistance mechanism releases the limitation on the rotating disk 2. Then, by pushing the shell body, the shell body can drive the rotating disk 2 to rotate synchronously, thereby achieving the purpose of adjusting the welding angle. After the adjustment is completed, the downward pressure applied to the resistance mechanism is removed. At this time, the resistance mechanism resets and limits the position of the adjusted shell body.

[0020] Please refer to this carefully. Figure 2 and Figure 3 The adsorption mechanism includes an air hole 16 located inside the rotating disk 2 and extending downward to the bottom of the rotating shaft 5. A connector 17 is rotatably mounted on the lower inner wall of the air hole 16. A sealing ring is provided on the outer periphery of the connector 17. An exhaust pipe 6 is integrally formed at the bottom of the connector 17, extending through to the bottom of the rotating shaft 5. An air pump 7 is installed at the output end of the exhaust pipe 6. An output pipe 8 is connected to the output end of the air pump 7. A one-way exhaust valve 9 is installed on the output pipe 8. The adsorption mechanism also includes a connecting pipe 10 connected to the input end of the exhaust pipe 6 via a three-way pipe. A manual valve 11 is installed on the connecting pipe 10.

[0021] In this embodiment: when the air pump 7 is running, the suction generated by the air pump 7 will draw out the gas in the connecting pipe 10, the air hole 16 and the exhaust pipe 6. At this time, the outer shell body is pressed tightly against the top of the rotating disk 2 due to the decrease in external air pressure. At this time, the rubber layer at the top of the rotating disk 2 deforms to prevent external air from entering the air hole 16 from the contact position between the top of the rotating disk 2 and the outer shell body, thus forming a vacuum adsorption.

[0022] After welding is completed, manually open the manual valve 11. When the manual valve 11 is opened, external air enters the air hole 16 through the connecting pipe 10. At this time, the connection achieved by negative pressure can be canceled, and the welded outer shell can be removed.

[0023] Please refer to this carefully. Figure 2and Figure 3 The resistance mechanism includes two guide rods 12 welded to one side of the bottom of the workbench 1. The outer sides of the two guide rods 12 are slidably connected to the same pressure plate 13. A connecting rod 15 is fixedly installed at the center of the bottom end of the pressure plate 13. An upwardly extending abutment plate 4 is integrally formed at the center of the top end of the connecting rod 15. The abutment plate 4 extends through to the top of the workbench 1. A rubber layer is adhered to the top of the abutment plate 4. A spring 14 is abutted between the bottom end of the pressure plate 13 and the protruding part of the bottom end of the guide rod 12. The spring 14 is sleeved on the outer periphery of the guide rod 12. A foot pedal is installed at the lower end of the connecting rod 15.

[0024] In this embodiment: When adjusting the welding angle of the outer shell body, a downward stepping force is applied to the foot pedal, which drives the connecting rod 15 to move synchronously. The connecting rod 15 then drives the pressure plate 13 to move downward. At this time, the two springs 14 are compressed, and the downward-moving pressure plate 13 synchronously drives the abutment plate 4 to move downward. At this time, the rubber layer at the top of the abutment plate 4 separates from the rubber layer at the bottom of the rotating disk 2, and the resistance disappears. The rotating disk 2 can then be rotated synchronously by rotating the outer shell body, thus achieving the purpose of adjusting the welding angle. After the angle adjustment is completed, the stepping force applied to the foot pedal is removed, and the spring 14 returns to its original position. The spring 14 pushes the pressure plate 13 to return to its original position, and the pressure plate 13 drives the abutment plate 4 to return to its original position. At this time, the rubber layer at the top of the abutment plate 4 abuts against the rubber layer at the bottom of the rotating disk 2, thus limiting the position of the rotating disk 2 and preventing the rotating disk 2 from rotating arbitrarily during the welding process.

[0025] Please refer to this carefully. Figure 1 The workbench 1 has a through groove 3 for the support plate 4 to pass through.

[0026] In this embodiment, the through groove 3 is designed to allow the abutment plate 4 to move up and down within the through groove 3.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
