Description

Technical Field

[0001] This utility model relates to the technical field of equipment for processing automotive copper busbars, specifically a fixing device for processing automotive copper busbars. Background Technology

[0002] Copper busbars, also known as copper busbars or copper busbars, are long conductors made of copper with a rectangular or chamfered rectangular cross-section. Nowadays, rounded-corner copper busbars are generally used to prevent point discharge. They are used to transmit current and connect electrical equipment in circuits. Copper busbars are widely used in electrical equipment, especially in complete sets of power distribution equipment. Generally, both the phase busbars and busbars in the distribution cabinet are made of copper. Copper busbars are usually marked with phase color letters or painted with phase color paint.

[0003] Currently, the common hanging tools used for electroplating automotive copper busbars typically employ single-point hooks to suspend the copper busbars. Because single-point suspension lacks effective constraint on the copper busbars, they may tilt or sway during the electroplating process, resulting in uneven flow of the electroplating solution and variations in plating thickness.

[0004] Therefore, a fixing device for processing automotive copper busbars is proposed to address the above problems. Utility Model Content

[0005] To overcome the shortcomings of existing technologies and address the problem of poor electroplating uniformity caused by the lack of effective limiting, this utility model proposes a fixing device for processing automotive copper busbars.

[0008] Preferably, a number of vertical rods are fixedly installed in the middle part of the inside of the hanging frame, and a number of connecting sleeves are sleeved on the surface of the vertical rods.

[0011] Preferably, a linkage rod is fixedly installed at the middle part of the top of the lifting frame, and a flange is fixedly installed at the top of the linkage rod.

[0021] 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 scope of protection of the present utility model.

[0022] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0023] This application discloses a fixing device for processing automotive copper busbars, including a hanging frame 1. Several assembly plates 2 are fixedly installed on the inner edge of the hanging frame 1. Several T-shaped positioning pins 3 are fixedly installed on the front of the assembly plates 2. An annular limiting piece 4 is fixedly installed at the end of the T-shaped positioning pins 3. A vertical groove 5 is fixedly opened on the outer side of the assembly plate 2 and at the bottom of the T-shaped positioning pins 3. A storage cylinder 6 is movably installed inside the vertical groove 5. A first spring 7 is movably installed in the inner cavity of the storage cylinder 6. A first T-shaped rod 8 is movably installed in the inner cavity of the storage cylinder 6 and outside the first spring 7. An annular limiting block 9 is fixedly installed at the end of the first T-shaped rod 8.

[0024] Reference Figure 1 , Figure 2 , Figure 4 Through the structural design of the assembly plate 2, T-shaped positioning pin 3, annular limiting plate 4, storage tube 6, first spring 7, first T-shaped rod 8, and annular limiting block 9, and through the mutual cooperation between the structures, the function of constraining the copper busbar is realized. Thus, the top T-shaped positioning pin 3 and the bottom first T-shaped rod 8 can be embedded into the upper and lower punch holes of the copper busbar respectively to form a two-way mechanical lock, which restricts the lateral swing and longitudinal sliding of the copper busbar in the electroplating tank, avoids the displacement caused by solution flow or vibration, and keeps the copper busbar stable in the complex electroplating environment.

[0025] A T-shaped cavity 10 is provided on one side of the surface of the annular limiting block 9. A second spring 11 is movably installed inside the T-shaped cavity 10. A second T-shaped rod 12 is movably installed inside the T-shaped cavity 10 and outside the second spring 11.

[0026] Reference Figure 4 The T-shaped cavity 10 facilitates the provision of installation space for the second spring 11 and the second T-shaped rod 12, while also supporting one end of the second spring 11 to ensure stable release of tension during subsequent contraction. The second spring 11 allows for the second T-shaped rod 12 to be inserted into the T-shaped cavity 10 using its retractable characteristics. Furthermore, the tension can be used to quickly reset the second T-shaped rod 12. The second T-shaped rod 12 can be extended laterally and inserted into the punched holes at the bottom of copper busbars of different shapes to constrain the bottom of the copper busbars after twisting, thereby increasing the applicability of the device and achieving the goal of increasing the flexibility of the overall fixing device.

[0027] Several vertical rods 13 are fixedly installed in the middle part of the inside of the hanging frame 1, and several connecting sleeves 14 are sleeved on the surface of the vertical rods 13.

[0028] Reference Figure 1 and Figure 3 The vertical rod 13 facilitates the connection and strength of the overall hanging frame 1, while providing installation space for the connecting sleeve 14. The connecting sleeve 14 facilitates the fitting of the vertical rod 13 onto the surface, thereby ensuring the verticality of the first T-shaped rod 8 during subsequent lifting and lowering.

[0029] An extension tube 15 is fixedly installed on one side of the surface of the connecting sleeve 14. A third spring 16 is movably installed in the inner cavity of the extension tube 15. A T-shaped connecting rod 17 is movably installed in the inner cavity of the extension tube 15 and outside the third spring 16.

[0030] Reference Figure 3 and Figure 4 The extension tube 15 facilitates the provision of installation space for the third spring 16 and the T-shaped connecting rod 17. At the same time, it provides overlapping space between the T-shaped connecting rod 17 and the extension tube 15 to facilitate subsequent adjustment of the height of the first T-shaped rod 8. The T-shaped connecting rod 17 facilitates the increase of the connection between the extension tube 15 and the arc-shaped abutment plate 18.

[0031] An arc-shaped abutment plate 18 is fixedly installed at the end of the T-shaped connecting rod 17. The outer side of the arc-shaped abutment plate 18 is fixedly connected to the storage tube 6, and the outer arc surface of the arc-shaped abutment plate 18 is adapted to the arc of the back of the assembly plate 2.

[0032] Reference Figure 3 The curved abutment plate 18 facilitates the tension of the third spring 16, positioning the connecting sleeve 14 and the second T-shaped rod 12, while also meeting the usage requirements of copper busbar constraints of different lengths.

[0033] A linkage rod 19 is fixedly installed at the middle part of the top of the hanging frame 1, and a flange 20 is fixedly installed at the top of the linkage rod 19.

[0034] Reference Figure 1 The linkage rod 19 and flange 20 facilitate connection with external hoisting equipment, making it easy to hoist the device with the fixed copper busbar to the processing station or electroplating tank.

[0035] Working principle: When using this device, the T-shaped positioning pin 3 is inserted into the top punch hole of the copper busbar, and the top of the copper busbar is constrained by the annular limiting piece 4. The storage cylinder 6 is pressed and held, and the storage cylinder 6, in conjunction with the arc-shaped abutment plate 18, drives the T-shaped connecting rod 17 to press the third spring 16. The storage cylinder 6 moves up and down inside the vertical groove 5, driving the first T-shaped rod 8 to move to the bottom punch hole of the copper busbar. During this process, the connecting sleeve 14 moves up and down on the surface of the vertical rod 13 to limit the storage cylinder 6, release the extension cylinder 15, and the third spring 16 releases tension to push the T-shaped connecting rod 17 to press the arc-shaped abutment plate 18. The arc-shaped abutment plate 18 contacts the inner wall of the assembly plate 2 to complete the fixation. The second T-shaped rod 12 compresses the second spring 11. After the first T-shaped rod 8 is inserted into the bottom punch hole of the copper busbar, the bottom of the copper busbar is constrained by the annular limiting block 9, thus completing the overall constraint of the copper busbar. When the copper busbar is twisted, the second spring 11 pushes the second T-shaped rod 12 to be inserted into the bottom punch hole of the twisted copper busbar.

[0036] 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.
