Description

Technical Field

[0001] This utility model belongs to the field of terminal welding tooling technology, and specifically relates to a tooling device for terminal welding. Background Technology

[0002] Currently, existing fixture-fixed products require manual installation of screws to fix the modules, with 8 screws installed at a time. After welding, the screws need to be removed again, with 8 screws installed each time, which is very tedious. Moreover, only one module can be welded at a time, resulting in low efficiency. The screws are strong and can easily damage the heat sink. In view of this, this solution was developed. Utility Model Content

[0003] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is to provide a tooling device for terminal welding that can simplify the welding process.

[0004] To solve the above-mentioned technical problems, the present invention adopts a terminal welding tooling device, including a driving component, a welding limiting frame, a pull plate, and a limiting pressure frame. The pull plate has a terminal plate placement area, and the limiting pressure frame is used to limit the terminal plate in the terminal plate placement area. The driving component is used to drive the welding limiting frame to move up and down. The pull plate is located below the welding limiting frame. The pull plate moves back and forth, causing the terminal plate placement area to enter or move away from the limiting area of ​​the welding limiting frame.

[0005] Furthermore, the drive assembly includes two drive cylinders, and connecting plates are formed on both sides of the welded limiting frame. The output end of the drive cylinder is detachably connected to the connecting plate.

[0006] Furthermore, extension plates are formed on both sides of the limiting pressure frame, and the extension plates are detachably connected to the upper surface of the pull-out plate through connectors.

[0007] Furthermore, an arc-shaped groove is formed on the inner ring sidewall of the welding limiting frame, and a limiting rod is formed on the upper surface of the limiting pressure frame, the limiting rod being adapted to the arc-shaped groove.

[0008] Furthermore, the number of arc-shaped grooves is two, and they are arranged diagonally at the top and bottom, and the number of limiting rods is the same as the number of arc-shaped grooves.

[0009] Furthermore, the drive assembly and welding limiting frame are in two sets, with the two sets of drive assemblies and welding limiting frames arranged at intervals, and the pull-out plate has two terminal plate placement areas.

[0010] Furthermore, two opposing guide rails are formed below the welding limiting frame, and a sliding groove is formed on the side of the two opposing guide rails facing each other. A slider bar is formed on the side of the pull plate, and the slider bar is adapted to the sliding groove.

[0011] Furthermore, a protruding plate is formed below the pull-out plate, and the slider bar is located on both sides of the protruding plate.

[0012] Furthermore, a stop plate is formed at the rear end of the opposing rail, which is used to prevent the pull plate from continuing to advance.

[0013] Furthermore, the drive assembly also includes an operating handle, which is used to drive a single set or both sets of drive cylinders to operate synchronously.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. This utility model limits the terminal by placing it into the limiting frame, and then moving the terminal plate into the lower part of the welding limiting frame by the back-and-forth movement of the pull plate. The drive component drives the welding limiting frame to move down to limit the pressure frame, and then the terminal is welded. This solution eliminates the need to manually remove the fixing screws to fix the terminal plate, which is highly efficient. In addition, the limiting frame contacts the heat sink surface of the terminal plate, so it will not cause pressure damage.

[0016] 2. By setting two terminal block placement areas and two welding limit frames in the pull-out plate, two terminal blocks can be loaded and welded at the same time, which is more efficient. Attached Figure Description

[0022] To make the above-mentioned features and advantages of this utility model more apparent and understandable, specific embodiments are described below in conjunction with the accompanying drawings for detailed explanation.

[0023] like Figures 1-4 As shown, this embodiment provides a tooling device for terminal welding, including a base 1, a drive assembly, a welding limiting frame 3, a pull-out plate 4, and a limiting pressure frame 5.

[0024] The drive assembly is set on the upper surface of the base 1. The drive assembly is used to drive the welding limit frame 3 to move up and down. Specifically, there are two sets of drive assemblies and welding limit frames 3. The two sets of drive assemblies and welding limit frames 3 are arranged at intervals. The drive assembly includes two drive cylinders 2 and an operating handle 21. Connecting plates 31 are formed on both sides of the welding limit frame 3. A partition is provided between the output end of the drive cylinder 2 and the connecting plate 31. The connection is made by bolts passing through the connecting plate 31, the partition and the surface of the output end of the drive cylinder 2.

[0025] Two opposing guide rails 22 are formed below the welding limiting frame 3. A groove 221 is formed on the side of the two opposing guide rails 22 facing each other. The pull-out plate 4 has a terminal plate placement area. The pull-out plate 4 is located below the welding limiting frame 3. The pull-out plate 4 moves back and forth, causing the terminal plate placement area to enter or move away from the limiting area of ​​the welding limiting frame 3. Specifically, a handle 41 is provided on the forward-facing side of the pull-out plate 4, and a protruding plate 42 is formed below the pull-out plate 4. Sliding bars 421 are located on both sides of the protruding plate 42. Alternatively, the protruding plate 42 can be omitted, and sliding bars 421 can be directly provided on both sides of the pull-out plate 4.

[0026] A stop plate 11 is formed at the rear end of the opposing rail 22. The stop plate 11 is used to block the pull plate 4 from continuing to advance and is a structure that stops it in place.

[0027] The limiting frame 5 is used to limit the terminal board in the terminal board placement area. The terminal board includes a heat dissipation panel and a terminal welding area on the heat dissipation panel. The limiting frame 5 divides the terminal welding area into three regions. Extension plates 52 are formed on both sides of the limiting frame 5. The extension plates 52 are fastened to the upper surface of the pull-out plate 4 by screws through connectors. An arc-shaped groove 32 is formed on the inner ring side wall of the welding limiting frame 3. A limiting rod 51 is formed on the upper surface of the limiting frame 5. The limiting rod 51 is adapted to the arc-shaped groove 32. There are two arc-shaped grooves 32, which are arranged diagonally at the top and bottom. The number of limiting rods 51 is the same as the number of arc-shaped grooves 32. During the up and down movement of the welding limiting frame 3, the limiting rod 51 extends into the arc-shaped groove 32 to perform the function of up and down positioning. The positional relationship between the limiting rod 51 and the arc-shaped groove 32 determines whether the inner frame of the welding limiting frame 3 is aligned with the limiting frame 5.

[0028] This solution limits the terminal by placing it into the limiting frame 5. The pull plate 4 moves back and forth, bringing the terminal plate under the welding limiting frame 3. The drive component drives the welding limiting frame 3 to move down the frame column limiting frame 5, and then the terminal is welded. This solution eliminates the need to manually remove the fixing screws to fix the terminal plate, which is highly efficient. In addition, the limiting frame 5 contacts the heat sink surface of the terminal plate, so it will not cause pressure damage.

Those skilled in the art should understand that this invention is not limited to the above embodiments.
