[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0026] Example 1: Please refer to Figures 1 to 6 :
[0027] This utility model proposes an auxiliary structure for inverter sheet metal, including: a base plate 1; an adjustable support plate 2 welded to the left and right sides of the top of the base plate 1, the base plate 1 is used to support the upper part of the structure of the device, and the adjustable support plate 2 is used to provide rotational support for the side support plate 6; two sets of four guide rods 3 are also welded to the left and right sides of the top of the base plate 1, and a spring 4 is installed on the outer side of each of the four guide rods 3; a lower pressure plate 5 is slidably installed between the two sets of guide rods 3 at the top of the base plate 1, the guide rods 3 at the top of the base plate 1 are used to provide sliding support for the lower pressure plate 5, and the spring 4 is used to push the lower pressure plate 5 to slide downward, the lower pressure plate 5 can clamp the sheet metal parts placed on the top of the base plate 1; the two adjustable support plates 2 are rotatably installed between each other. There is a side support plate 6. On the top left and right sides of the side support plate 6, a positioning screw 7 is screwed on. The side support plate 6 and the side pressure plate 8 cooperate to clamp another sheet metal part. After the positioning screw 7 is tightened, the angle of the side support plate 6 is fixed. There are also two sets of four guide rods 3 welded on the front left and right sides of the side support plate 6. A side pressure plate 8 is slidably installed on the outside of the guide rod 3 in front of the side support plate 6. Two screw rods 9 are also rotatably installed on the front left and right sides of the side support plate 6. The guide rod 3 in front of the side support plate 6 is used to slide support the side pressure plate 8. The side pressure plate 8 and the side support plate 6 cooperate to clamp another sheet metal part. When the screw rod 9 rotates, the position of the side pressure plate 8 can be adjusted.
[0028] In this embodiment, as Figure 1 , Figure 3 and Figure 5As shown, the side pressure plate 8 has two round holes on both the left and right sides that correspond to the size of the guide rod 3 in front of the side support plate 6. The side pressure plate 8 can slide back and forth on the outside of the guide rod 3 in front of the side support plate 6. Therefore, the distance between the side pressure plate 8 and the side support plate 6 can be adjusted to facilitate clamping the sheet metal parts that need to be welded.
[0029] In this embodiment, as Figures 1-3 As shown, the lower pressure plate 5 is an I-shaped plate. The bottom end of the spring 4 is in close contact with the top surface of the lower pressure plate 5 and can push the lower pressure plate 5 to slide downward. When in use, the lower pressure plate 5 can be pulled up by the handle on the top of the lower pressure plate 5, and one of the sheet metal parts to be welded can be placed on the top of the base plate 1. At this time, the lower pressure plate 5 can be released. At this time, the spring 4 on the outside of the guide rod 3 at the top of the base plate 1 will push the lower pressure plate 5 to slide downward, so that the bottom surface of the lower pressure plate 5 can be in close contact with the top surface of the sheet metal part, thereby clamping the sheet metal part placed on the top of the base plate 1.
[0030] In this embodiment, as Figure 1 , Figure 3 , Figure 5 and Figure 6 As shown, the left and right sides of the side pressure plate 8 are each provided with a threaded hole corresponding to the outer thread of the lead screw 9. The front end of the lead screw 9 is provided with a hexagonal groove. When in use, the two lead screws 9 can be rotated by an Allen wrench. When the lead screw 9 rotates, it will slide back and forth on the outside of the guide rod 3 in front of the side support plate 6 through the threaded holes on the left and right sides of the side pressure plate 8.
[0031] In this embodiment, as Figures 1-6 As shown, the adjustment support plates 2 are all semi-circular plates, and each adjustment support plate 2 has a circular hole at its center. The rotating shaft at the bottom of the side support plate 6 can rotate in the circular hole at the center of the adjustment support plate 2. Therefore, the side support plate 6 can be rotated and adjusted between the two adjustment support plates 2, which facilitates the positioning and welding of sheet metal parts at different tilt angles.
[0032] In this embodiment, as Figures 1-3 and Figure 5 and Figure 6 As shown, an L-shaped plate is provided on the top left and right sides of the side support plate 6. The L-shaped plate wraps around the outer wall of the adjusting support plate 2, and after the positioning screws 7 are tightened, their bottom ends will be in close contact with the outer wall of the adjusting support plate 2. When in use, the tilt angle of the side support plate 6 can be adjusted according to the angle that the other sheet metal part needs to be welded. When adjusting, simply loosen the two positioning screws 7 first, and then rotate the side support plate 6 between the two adjusting support plates 2 to adjust it to a suitable angle. Then tighten the two positioning screws 7 again. When the bottom ends of the positioning screws 7 are in close contact with the outer wall of the adjusting support plate 2, the angle of the side support plate 6 can be fixed.
[0033] Example 2, based on Example 1, such as Figures 1-6 As shown, the bottom surface of the lower pressure plate 5 and the rear side of the side pressure plate 8 are both covered with a layer of rubber. The top of the lower pressure plate 5 is also provided with a handle. When in use, the sheet metal parts placed on the top of the base plate 1 can be clamped by the lower pressure plate 5. The side pressure plate 8 and the side support plate 6 can cooperate to clamp another sheet metal part. At this time, the rubber on the bottom of the lower pressure plate 5 and the rubber on the rear side of the side pressure plate 8 can increase the friction and prevent the sheet metal parts from moving. The handle on the top of the lower pressure plate 5 can be easily pulled upwards.
[0034] The working principle of this embodiment is as follows: When welding the sheet metal housing of the inverter using this device, first place the base plate 1 on the processing table, then pull it upwards using the handle on the top of the lower pressure plate 5, and place one of the sheet metal parts to be welded on top of the base plate 1. At this time, the lower pressure plate 5 can be released. The spring 4 on the outside of the guide rod 3 at the top of the base plate 1 will push the lower pressure plate 5 downwards, so that the bottom surface of the lower pressure plate 5 can be tightly attached to the top surface of the sheet metal part, thereby clamping the sheet metal part placed on top of the base plate 1. Then, the tilt angle of the side support plate 6 can be adjusted according to the angle at which the other sheet metal part needs to be welded. To adjust, simply loosen the two positioning screws 7 first, and then the side support plate 6 can be adjusted between the two adjustable supports. Rotate and adjust between plates 2 until a suitable angle is reached, then tighten the two positioning screws 7 again. When the bottom end of the positioning screw 7 is in close contact with the outer wall of the adjusting support plate 2, the angle of the side support plate 6 can be fixed. Then, the two lead screws 9 can be rotated in opposite directions using an Allen wrench. At this time, the lead screws 9 will slide forward on the outside of the guide rod 3 in front of the side support plate 6 through the threaded holes on the left and right sides of the side pressure plate 8. In this way, another sheet metal part can be placed between the side support plate 6 and the side pressure plate 8, and the two sheet metal parts can be made to contact each other. Then, rotate the two lead screws 9 in the forward direction to make the side pressure plate 8 slide backward. In this way, the side pressure plate 8 and the side support plate 6 can cooperate to firmly clamp the sheet metal part placed between them. Then, the two sheet metal parts can be welded.
