Description

Technical Field

[0001] This utility model belongs to the field of water-cooled plate processing, and specifically relates to a positioning fixture for laser welding of water-cooled plates. Background Technology

[0002] As a core component for heat dissipation in electronic devices, the sealing performance and structural strength of water-cooled plates are of paramount importance. Laser welding, due to its high energy density and small heat-affected zone, has become a key process in the processing of water-cooled plates.

[0003] In existing technologies, laser welding of water-cooled plates typically employs general-purpose fixtures or simple positioning tools for fixation. These traditional toolings are usually simple in structure and have limited positioning accuracy, making it difficult to achieve precise and stable all-around constraint on workpieces like water-cooled plates, which have relatively precise structures and high flatness requirements. In practice, insecure positioning often leads to slight movement or displacement of the workpiece during welding, severely affecting the alignment and forming quality of the weld, easily causing defects such as porosity and incomplete fusion, and making it difficult to guarantee the yield rate.

[0004] Therefore, the above problems urgently need to be solved. Utility Model Content

[0005] Purpose of the utility model: In order to overcome the above shortcomings, the purpose of this utility model is to provide a positioning fixture for laser welding of water-cooled plates. Through the synergistic action of the positioning pin in the material placement slot of the lower plate and the stabilizing pin on the pressure plate, the water-cooled plate is accurately positioned and reliably pressed in the horizontal and vertical directions, effectively preventing movement during the welding process and ensuring the accuracy and consistency of the weld position. At the same time, the positioning block and positioning hole cooperate to achieve the quick and accurate installation of the pressure plate.

[0006] Technical Solution: To achieve the above objectives, this utility model provides a positioning fixture for laser welding of water-cooled plates, comprising a lower plate, an upper plate, and a pressure plate; a plurality of mounting columns are provided between the lower plate and the upper plate; the upper plate is mounted on the lower plate via the mounting columns; a plurality of upright columns are provided between the pressure plate and the lower plate; the pressure plate is mounted on the lower plate via the upright columns; the pressure plate is positioned above the upper plate; a plurality of stabilizing pins are provided on the pressure plate; the lower ends of the stabilizing pins abut against the water-cooled plate to be processed, thereby stabilizing the water-cooled plate; a material placement slot is provided in the middle of the lower plate; a plurality of positioning pins are provided on the material placement slot. The upper plate is mounted on the lower plate by mounting columns, and the pressure plate is mounted on the lower plate by upright columns, forming a layered and stable structure. This ensures that the relative positions of the components remain stable during processing, reducing displacement caused by vibration or external forces, thereby improving processing accuracy. At the same time, the pressure plate is equipped with stabilizing pins. The lower ends of these pins directly abut against the water-cooled plate to be processed, which can effectively fix the water-cooled plate and prevent it from moving or deforming during processing, further enhancing the stability of the entire tooling.

[0007] Furthermore, the positioning pins are located on both sides of the material placement slot. These positioning pins on both sides can restrict the horizontal movement of the water-cooled plate, ensuring it remains in the correct position during processing and improving processing accuracy.

[0008] Furthermore, the stabilizing pin is mounted on the pressure plate with a nut, which facilitates the installation and removal of the stabilizing pin. When it is necessary to replace or repair the stabilizing pin, simply unscrew the nut. The operation is simple and quick, improving the maintenance efficiency of the tooling.

[0009] Furthermore, the upper plate is also provided with several clearance grooves; the stabilizing pin passes through the clearance grooves and abuts against the water-cooled plate to be processed. The clearance grooves make way for the product to be processed, and together with the stabilizing pin, they ensure the clamping force of the water-cooled plate to be processed without damaging the surface design of the water-cooled plate.

[0010] Furthermore, a positioning block is provided at the middle of the upper end of the column. When installing the pressure plate, the positioning block can serve as a precise reference point, enabling the pressure plate to be accurately installed in the predetermined position and reducing installation errors.

[0011] Furthermore, the pressure plate is provided with positioning holes for positioning blocks; the positioning holes cooperate with the positioning blocks to position the pressure plate, which facilitates the installation of the pressure plate. The operator only needs to align the positioning holes on the pressure plate with the positioning blocks on the column to quickly complete the positioning and installation of the pressure plate, which improves the assembly efficiency of the tooling and saves preparation time before processing.

[0012] Furthermore, handles are provided on both sides of the lower plate, making the loading and unloading of workpieces simple and quick, greatly improving clamping efficiency and production cycle time. As can be seen from the above technical solution, this utility model has the following beneficial effects: 1. This utility model provides a positioning fixture for laser welding of water-cooled plates. Through the coordinated action of the positioning pin in the material placement slot of the lower plate and the stabilizing pin on the pressure plate, the water-cooled plate is accurately positioned and reliably pressed in the horizontal and vertical directions, effectively preventing movement during the welding process and ensuring the accuracy and consistency of the weld position. 2. This utility model provides a positioning fixture for laser welding of water-cooled plates. By cooperating with the positioning block and the positioning hole, the pressure plate can be installed quickly and accurately, thereby improving clamping efficiency and production cycle.

[0026] In this embodiment, as Figures 1 to 4 The lower plate 1 is also provided with handles 12 on both sides.

[0027] Specifically, the grip 12 can be textured to increase grip friction and facilitate workpiece handling.

[0028] The working principle of the above embodiments is as follows: This utility model discloses a positioning fixture for laser welding of water-cooled plates.
