Description

Technical Field

[0001] This utility model relates to the field of copper-aluminum sheet welding technology, and in particular to a copper-aluminum sheet welding fixture. Background Technology

[0002] The welding of copper and aluminum sheets is widely used in many industrial production scenarios. For example, in the manufacturing of heat dissipation modules for electronic devices, copper and aluminum sheets are often welded to take advantage of their excellent thermal conductivity. However, the existing copper and aluminum sheet welding fixtures have at least the following drawbacks: 1. Traditional welding fixtures are difficult to accurately position and stably clamp the copper and aluminum sheets. During welding, the copper and aluminum sheets are prone to displacement and shaking, which seriously affects the welding quality and accuracy, leading to frequent defects such as incomplete welding and detachment, and reducing product yield; 2. Existing fixtures lack good versatility and adaptability, often requiring frequent replacement of fixture parts or the entire fixture, which greatly increases production costs and operation time, and reduces production efficiency. Therefore, we have introduced a new copper and aluminum sheet welding fixture. Utility Model Content

[0003] The main objective of this invention is to provide a welding fixture for copper and aluminum sheets, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A copper-aluminum sheet welding fixture includes a supporting base plate. A plurality of positioning holes are equidistantly spaced on the right side of the front upper part of the supporting base plate. Two positioning blocks are fixedly connected to the lower left and lower right ends of the supporting base plate. A supporting assembly is fixedly connected to the upper upper part of the supporting base plate. Limit frames are fixedly connected to the upper left and upper right ends of the supporting assembly.

Two round rods are fixedly connected to the rear upper part of the supporting base plate, and a retaining frame is sleeved on the outer surface of both round rods.

[0006] The positioning component includes two support rods. A spring is sleeved on the lower part of the outer surface of each of the two support rods. A retaining frame is sleeved on the lower part of the outer surface of both support rods, and the retaining frame is located above the two springs. A support plate is fixedly connected to the upper end of both support rods. A limit screw is inserted through the middle of the upper end of the support plate. Both support rods are fixedly connected to the support component.

[0007] Preferably, the support assembly includes a support plate, with support rods fixedly connected to the front right end and the rear right end of the support plate, and a support plate sleeved on the outer surface of the two support rods.

[0024] Please see Figure 1-5 This utility model provides a technical solution:

[0025] A copper-aluminum sheet welding fixture includes a support base plate 1. Several positioning holes 2 are equidistantly opened on the right side of the front upper part of the support base plate 1. Two No. 1 positioning blocks 5 are fixedly connected to the lower left and lower right parts of the support base plate 1. A support assembly 3 is fixedly connected to the upper end of the support base plate 1. Limit frames 4 are fixedly connected to the upper left and upper right parts of the support assembly 3. Positioning components 8 are fixedly connected to the upper left and upper right parts of the support assembly 3. The two positioning components 8 are located between the two limit frames 4. Two round rods 7 are fixedly connected to the upper rear part of the support base plate 1. A stop frame 6 is sleeved on the outer surface of the two round rods 7.

[0026] In this embodiment, the positioning component 8 includes two support rods 81. A spring 82 is sleeved on the lower part of the outer surface of each support rod 81. A retaining frame 83 is sleeved on the lower part of the outer surface of each support rod 81, and the retaining frame 83 is located above the two springs 82. A support plate 84 is fixedly connected to the upper end of each support rod 81. A limit screw 85 is inserted through the middle of the upper end of the support plate 84. Both support rods 81 are fixedly connected to the support component 3. The two retaining frames 83 do not contact the stop frame 6.

[0027] With the above scheme, both support rods 81 are fixedly connected to the support component 3, thus providing a stable installation base for the positioning component 8 and achieving precise positioning of the positioning component 8. By rotating the limiting screw 85, a thrust can be generated on the clamping frame 83, causing the clamping frame 83 to make close contact with the copper and aluminum sheet device to be welded. This design can effectively prevent the copper and aluminum sheet from shaking and shifting during the welding process, significantly improving the operational accuracy of the copper and aluminum sheet welding process and laying a solid foundation for ensuring welding quality.

[0028] In this embodiment, the support assembly 3 includes a support plate 31. Support rods 32 are fixedly connected to the front and rear right ends of the support plate 31. A support plate 33 is sleeved on the outer surface of the two support rods 32. Anti-slip layers 34 are fixedly connected to the upper ends of the support plate 31 and the support plate 33. The support plate 31 is fixedly connected to the support base plate 1. The support plate 33 includes a plate body 331. A second positioning block 332 is fixedly connected to the lower left side of the front end of the plate body 331. A positioning screw 333 is inserted through the upper end of the second positioning block 332. Circular holes 334 are opened at the front and rear left ends of the plate body 331. The plate body 331 is fixedly connected to the anti-slip layer 34. The two support rods 32 are respectively inserted through the two circular holes 334. The positioning screw 333 passes through the second positioning block 332 and is inserted through the positioning hole 2.

[0029] The above solution involves connecting the support plate 33 to the two support rods 32, adjusting and fixing the distance between the support plate 31 and the anti-slip layer 34 by sliding the support plate 33 on the two support rods 32, and connecting the positioning screw 333 through the second positioning block 332 and the positioning hole 2. This facilitates the support plate 31 and the anti-slip layer 34 in supporting the welding process of copper and aluminum sheets of different lengths, avoids multiple tooling changes, and improves flexibility.

[0030] It should be noted that this utility model is a welding fixture for copper and aluminum sheets. During use, the baffle 6 is sleeved with two round rods 7. The round rods 7 provide stable support for the baffle 6, enabling it to provide protection during the welding process, blocking welding spatter and protecting the surrounding environment and operators. Next, the copper or aluminum sheet to be welded is placed on the support plate 31 and the tray 33. At this point, rotating the two limiting screws 85 generates a pushing force on the two clamping frames 83, causing them to make close contact with the copper or aluminum sheet to be welded. This structural design utilizes the clamping force of the clamping frames 83 to effectively prevent the copper or aluminum sheet from shaking or shifting position during welding. This significantly improves the precision of the copper-aluminum sheet welding process, providing a foundation for ensuring welding quality. Simultaneously, the support plate 33 is connected to the two support rods 32 via a sleeve connection. By sliding the support plate 33 on the two support rods 32, the distance between the support plate 31 and the anti-slip layer 34 can be adjusted. After adjustment, the adjusted distance is fixed by using a positioning screw 333 to pass through the second positioning block 332 and the positioning hole 2, and then locking it in place. This design allows the support plate 31 and the anti-slip layer 34 to adapt to the welding process of copper-aluminum sheets of different lengths, providing stable support and avoiding the need for multiple tooling changes due to varying copper-aluminum sheet lengths, greatly improving the flexibility of tooling use.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
