Description

Technical Field

[0001] This utility model relates to a novel vacuum brazing fixture for water-cooled plates. Background Technology

[0002] As a core component of the thermal management system for new energy vehicle battery packs, the water-cooled plate's internal flow channel structure's sealing and thermal conductivity directly affect its heat dissipation efficiency. Vacuum brazing is currently a key process in manufacturing water-cooled plates, achieving a metallurgical bond between the flow channels and the cover plate by melting the brazing filler metal at high temperatures in a vacuum environment. This process requires the workpiece to maintain absolute positioning stability and uniform compression during welding to avoid sealing failure or flow channel deformation due to thermal deformation.

[0003] However, traditional vacuum brazing fixtures for water-cooled plates generally employ fixed limiting structures, which cannot flexibly adjust the limiting and clamping positions. Due to the diverse sizes and specifications of water-cooled plates (e.g., square, irregular shapes) and varying requirements for clamping areas (e.g., flow channel junctions, edge sealing areas), fixed limiting structures have poor applicability to different products and are prone to clamping blind spots. Therefore, this invention proposes a novel vacuum brazing fixture for water-cooled plates to solve these problems. Utility Model Content

[0004] The purpose of this invention is to provide a novel vacuum brazing fixture for water-cooled plates to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A novel vacuum brazing fixture for water-cooled plates includes a placement plate, on which two sets of placement screws are provided, the two sets of placement screws being symmetrically arranged.

[0007] Multiple sets of movable frames are provided between the two sets of placement screws. Each movable frame is provided with a movable plate. A limit slot is provided on the movable plate. Multiple sets of limit components are provided in the limit slot. The movable frame also cooperates with the placement screws so that the multiple sets of limit components are adjusted to the pressing position on the placement plate.

[0008] As an improvement to the above technical solution, the movable plate is provided with movable plates at both ends, and a placement threaded sleeve is rotatably provided on the movable plate, and the placement screw is threaded in the placement threaded sleeve.

[0009] As an improvement to the above technical solution, the two ends of the placement screw are provided with reinforcing plates, and the reinforcing plates are connected to the placement plate;

[0010] The outer wall of the sleeve containing the threaded sleeve is fitted with a nut.

[0011] As an improvement to the above technical solution, a fixing plate is provided on the movable plate, and the fixing plate is arranged towards the center of the placement plate;

[0012] Two sets of fixing screws are rotatably mounted on the fixed plate. The fixing screws pass through the movable plate and are threadedly connected to the movable plate.

[0013] As an improvement to the above technical solution, the movable plate is also provided with a fixing through groove, and the fixing through groove is matched with the limiting through groove in position;

[0014] The limiting component includes a limiting block, which is slidably disposed in a fixed through groove. A fixing block is disposed on the limiting block, and the fixing block is slidably disposed in the fixed through groove.

[0015] As an improvement to the above technical solution, a through-hole limiting screw is provided on the limiting block, and the limiting screw is threadedly connected to the limiting block;

[0016] The bottom end of the limiting screw is provided with a limiting pressure plate, which is rotatably connected to the limiting screw. The limiting pressure plate is set towards the placement plate. The limiting screw is also provided with a rotating handwheel, which is set away from the placement plate.

[0017] As an improvement to the above technical solution, the limiting screw is threaded with a limiting nut;

[0018] The limiting screw is provided with a limiting ring plate, which is sleeved on the outer wall of the limiting screw.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] By cooperating with two sets of symmetrically arranged placement screws and multiple sets of moving frames, the overall position of the limiting component can be adjusted on the placement plate; combined with the displacement capability of the limiting component in the limiting through groove, flexible adaptation to different pressing areas of the water-cooled plate is achieved. This structure effectively solves the problem of limited applicability caused by fixed limiting points in traditional tooling, and significantly improves the compatibility of tooling with water-cooled plates of different sizes and shapes.

[0021] After the moving frame moves the limiting component above the water-cooled plate, the limiting component can be finely adjusted along the limiting through groove to ensure that the pressing position is precisely aligned with the required area of ​​the workpiece. The limiting screw applies vertical pressure to the water-cooled plate to form a stable multi-point pressing mechanism, preventing workpiece displacement or deformation during brazing and ensuring welding accuracy.

[0029] 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 protection scope of the present utility model.

[0030] Example:

[0031] like Figure 1-6 As shown, this embodiment proposes a novel vacuum brazing fixture for water-cooled plates, including a placement plate 10, on which two sets of placement screws 20 are provided, and the two sets of placement screws 20 are symmetrically arranged.

[0032] Multiple sets of movable frames 30 are provided between the two sets of placement screws 20. Each movable frame 30 is provided with a movable plate 32. A limiting groove 321 is provided on the movable plate 32. Multiple sets of limiting components 40 are provided in the limiting groove 321. The movable frame 30 also cooperates with the placement screws 20 so that the multiple sets of limiting components 40 are adjusted to the pressing position on the placement plate 10.

[0033] In this embodiment, before vacuum brazing the water-cooled plate, the water-cooled plate is placed on the placement plate 10 until the placement screw 20 drives the moving frame 30 to move, so that the limiting component 40 on the moving frame 30 moves to above the water-cooled plate. Then, the limiting component 40 moves in the limiting through groove 321, so that the limiting component 40 is aligned with the area to be pressed, and the water-cooled plate is pressed and limited by the limiting component 40 until multiple sets of limiting components 40 complete the pressing and limiting process.

[0034] By cooperating with two sets of symmetrically arranged placement screws 20 and multiple sets of moving frames 30, the limiting component 40 can be adjusted in its overall position on the placement plate 10; combined with the displacement capability of the limiting component 40 in the limiting through groove 321, flexible adaptation to different pressing areas of the water-cooled plate is achieved. This structure effectively solves the problem of limited applicability caused by fixed limiting points in traditional tooling, and significantly improves the compatibility of tooling with water-cooled plates of different sizes and shapes.

[0035] After the moving frame 30 moves the limiting component 40 above the water-cooled plate, the limiting component 40 can be finely adjusted along the limiting through groove 321 to ensure that the pressing position is precisely aligned with the required area of ​​the workpiece. The limiting screw 42 applies vertical pressure to the water-cooled plate to form a stable multi-point pressing mechanism, preventing workpiece displacement or deformation during brazing and ensuring welding accuracy.

[0036] Specifically, the movable plate 32 is provided with movable plates 31 at both ends, and a placement threaded sleeve 313 is rotatably provided on the movable plate 31, and the placement screw 20 is threaded in the placement threaded sleeve 313.

[0037] In this embodiment, the threaded sleeve 313 is rotated and driven to move along the axial direction of the placement screw 20, thereby causing the moving plate 32 and the limiting component 40 to move as a whole, so as to restrict the water-cooled plate at different positions.

[0038] Specifically, the two ends of the placement screw 20 are provided with reinforcing plates 21, and the reinforcing plates 21 are connected to the placement plate 10;

[0039] The outer wall of the threaded sleeve 313 is fixedly fitted with a nut 314.

[0040] In this embodiment, the placement nut 314 facilitates the rotation of the placement threaded sleeve 313 for adjustment.

[0041] Specifically, a fixing plate 312 is provided on the movable plate 31, and the fixing plate 312 is arranged towards the center of the placement plate 10;

[0042] Two sets of fixing screws 311 are rotatably provided on the fixing plate 312. The fixing screws 311 pass through the movable plate 31 and are threadedly connected to the movable plate 31.

[0043] In this embodiment, after the movable plate 31 is adjusted to a suitable position, the movable plate 31 is moved toward the center of the placement plate 10 by the threaded engagement of the fixing screw 311 and the movable plate 31, until the movable plate 31 contacts the side wall of the water-cooled plate, which can effectively restrict the side wall of the water-cooled plate.

[0044] Specifically, the movable plate 32 is also provided with a fixing slot 322, which is matched with the position of the limiting slot 321;

[0045] The limiting component 40 includes a limiting block 43, which is slidably disposed in the fixed through groove 322. A fixing block 44 is disposed on the limiting block 43, and the fixing block 44 is slidably disposed in the fixed through groove 322.

[0046] In this embodiment, the sliding of the limiting block 43 in the limiting through groove 321 and the fixing block 44 in the fixing through groove 322 form a dual guiding mechanism, which ensures that the movement trajectory of the limiting component 40 in the horizontal direction is precise and controllable. It can be finely adjusted and positioned according to the pressing requirements of different areas of the water-cooled plate, effectively overcoming the problem of insufficient adjustment flexibility caused by the fixed limiting point of traditional tooling.

[0047] Specifically, the limiting block 43 is provided with a through limiting screw 42, and the limiting screw 42 is threadedly connected to the limiting block 43;

[0048] The bottom end of the limiting screw 42 is provided with a limiting pressure plate 46, which is rotatably connected to the limiting screw 42. The limiting pressure plate 46 is arranged towards the placement plate 10. The limiting screw 42 is also provided with a rotating handwheel 41, which is arranged away from the placement plate 10.

[0049] In this embodiment, a quantifiable adjustable vertical pressure mechanism is formed by the threaded engagement of the limiting screw 42 and the limiting block 43. The axial displacement of the limiting screw 42 is driven by rotating the handwheel 41, thereby achieving linear control of the downward pressure of the limiting plate 46. At the same time, the rotational connection design between the limiting plate 46 and the limiting screw 42 prevents the limiting screw 42 from causing the limiting plate 46 to rotate during rotation.

[0050] Specifically, the limiting screw 42 is threaded with a limiting nut 47;

[0051] The limiting screw 42 is provided with a limiting ring plate 45, which is sleeved on the outer wall of the limiting screw 42.

[0052] In this embodiment, after the limiting pressure plate 46 contacts the surface of the water-cooled plate, by rotating the limiting nut 47, the limiting ring plate 45 contacts the bottom end of the moving plate 32 under the threaded engagement of the limiting nut 47 and the limiting screw 42, thereby restricting the limiting block 43 and improving the limiting ability.

[0053] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
