Description

Technical Field

[0001] This utility model relates to a clamping device for friction stir welding of water-cooled plates. Background Technology

[0002] In the fields of new energy vehicles, energy storage systems, and high-power electronic equipment, water-cooled plates are core heat dissipation components, and their welding quality directly determines the thermal management performance and reliability of the equipment. Friction stir welding technology, due to its solid-state bonding characteristics, has become a key process in the manufacturing of water-cooled plates.

[0003] Existing pressure fixtures mostly adopt a vertical unidirectional pressing structure, lacking a lateral constraint mechanism, and cannot form a multi-dimensional force field balance. This causes the plate to undergo three-dimensional deformation due to stress release during the welding process, which seriously affects the straightness and sealing performance of the weld. In view of this, this utility model proposes a pressing device for water-cooled plate friction stir welding to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a clamping device for water-cooled plate friction stir welding, so as to solve the problems mentioned in the background art.

An adjustment component is also provided on the downward pressure rod.

[0034] 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.

[0035] Example:

[0036] like Figure 1-10 As shown, this embodiment proposes a clamping device for water-cooled plate friction stir welding, including a placement plate 10, on which two sets of limiting T-shaped guide rails 11 are symmetrically arranged, and multiple sets of movable seats 30 that can be displaced are arranged on the limiting T-shaped guide rails 11.

[0037] A lower pressure rod 20 is hinged to the movable seat 30. A lower pressure pad 22 and a moving rod 50 are provided on the lower pressure rod 20. An adjustment component 40 is also provided on the lower pressure rod 20. The adjustment component 40 cooperates with the moving rod 50 so that the moving rod 50 moves toward the lower pressure pad 22 and contacts the water-cooled plate for clamping and limiting.

[0038] In this embodiment, when performing friction stir welding on the water-cooled plate, the water-cooled plate is placed on the placement plate 10, and then the movable seat 30 is moved on the limiting T-shaped guide rail 11. The position of the movable seat 30 is adjusted so that multiple sets of pressure rods 20 are evenly distributed and the pressure pads 22 are pressed down to contact the water-cooled plate, thus limiting the water-cooled plate for the first time. Then, the movable rod 50 is moved towards the pressure pad 22 by the adjustment component 40 until the movable rod 50 contacts the side of the water-cooled plate, thus completing the second limiting. After the multiple sets of pressure pads 22 and multiple sets of movable rods 50 contact the water-cooled plate, the final pressing and limiting is completed.

[0039] The lower pressure pad 22 vertically presses against the surface of the water-cooled plate to form a primary limit, and the adjustment component 40 drives the moving rod 50 to move laterally to achieve a secondary limit on the side, forming a multi-dimensional three-dimensional pressing structure. This design effectively eliminates the warping deformation of the plate during welding, ensures that all parts of the water-cooled plate are evenly stressed, and significantly improves the pressing stability and the quality of the welded joint.

[0040] By adjusting the sliding position of the movable seat 30 along the limiting T-shaped guide rail 11, the position of multiple sets of pressure rods 20 can be adjusted infinitely in the plane. This feature enables the device to quickly adapt to the size changes of water-cooled plates of different specifications, expands the versatility of the equipment, and solves the technical bottleneck of poor applicability of traditional fixed pressure fixtures.

[0041] Specifically, the limiting T-shaped guide rail 11 is provided with placement blocks 12 at both ends, and the placement blocks 12 are connected to the placement plate 10;

[0042] A drive screw 13 is provided between the two sets of placement blocks 12. The drive screw 13 is arranged parallel to the limiting T-shaped guide rail 11, and the moving seat 30 cooperates with the drive screw 13.

[0043] Specifically, the movable seat 30 is provided with a T-shaped groove 34, the limiting T-shaped guide rail 11 is adapted to the T-shaped groove 34, and the limiting T-shaped guide rail 11 is slidably disposed in the T-shaped groove 34;

[0044] A drive sleeve 31 is provided on the movable seat 30. The drive sleeve 31 is rotatably mounted on the movable seat 30. The drive screw 13 is threaded in the drive sleeve 31. A drive hexagonal block 32 is provided on the outer wall of the drive sleeve 31.

[0045] In this embodiment, when adjusting the position of the movable seat 30, a wrench is placed on the driving hexagonal block 32 to drive the driving sleeve 31 to rotate. Through the threaded engagement between the driving sleeve 31 and the driving screw 13, the movable seat 30 is displaced.

[0046] By forming a dual guiding reference through the parallel arrangement of the drive screw 13 and the limiting T-shaped guide rail 11, and cooperating with the threaded engagement transmission between the drive sleeve 31 and the drive screw 13, a high-precision linear drive module is constructed. This design ensures that the displacement of the moving seat 30 on the limiting T-shaped guide rail 11 is strictly guided and controlled by the drive screw 13, achieving micron-level adjustment accuracy of the clamping point spacing, which is significantly better than the traditional manual positioning method.

[0047] Specifically, the pressing rod 20 is provided with a pressing threaded hole 25, and the pressing pad 22 is rotatably provided with a pressing screw 23, which is threadedly connected to the pressing threaded hole 25;

[0048] A pressing hexagonal block 24 is provided on the pressing screw 23.

[0049] In this embodiment, a height-adjustable pressing module is formed by the screw drive of the pressing screw 23 and the pressing threaded hole 25, which realizes the precise vertical adjustment of the pressing pad 22. This structure breaks through the limitation of the traditional fixed pressing pad 22 being non-adjustable, so that the contact pressure can be dynamically optimized according to the thickness of the plate.

[0050] Specifically, the pressing rod 20 is provided with a moving groove 21;

[0051] The adjustment assembly 40 includes two sets of mounting plates 43, which are symmetrically arranged in the moving groove 21. An adjustment screw 41 is rotatably arranged between the two sets of mounting plates 43. An adjustment plate 42 is arranged on the adjustment screw 41. The adjustment plate 42 is slidably arranged in the moving groove 21. The moving rod 50 is arranged on the adjustment plate 42.

[0052] Specifically, the adjusting plate 42 is provided with an adjusting threaded hole 44, and the adjusting screw 41 is threaded in the adjusting threaded hole 44;

[0053] An adjustment sleeve 45 is provided on the adjustment plate 42, and a moving screw 51 is provided on the moving rod 50. The moving screw 51 is threaded into the adjustment sleeve 45.

[0054] In this embodiment, when it is necessary to move the moving rod 50, the adjusting screw 41 is rotated, and the adjusting screw 41 is threadedly engaged with the adjusting threaded hole 44, so that the adjusting plate 42 is moved in the moving groove 21. Of course, when it is necessary to raise or lower the moving rod 50, the moving screw 51 is threadedly engaged with the adjusting sleeve 45, so that the moving rod 50 is lowered, so as to perform secondary positioning of the water cooling plate.

[0055] By adjusting the thread engagement between the screw 41 and the threaded hole 44 to form a transverse precision drive mechanism, and cooperating with the vertical threaded transmission between the moving screw 51 and the adjusting sleeve 45, a three-dimensional clamping system with XYZ three-axis linkage is constructed to achieve dynamic optimization of the clamping point position and angle, effectively eliminating multi-directional deformation caused by thermal stress during the welding process.

[0056] Specifically, a movable frame 33 is hinged to the movable seat 30, and a sliding rubber sleeve 35 is provided on the movable frame 33;

[0057] The movable frame 33 is provided with a connecting plate 38. The two ends of the connecting plate 38 are respectively hinged to the movable frame 33 and the movable seat 30. A limiting plate 36 is provided on the connecting plate 38. The limiting plate 36 is provided with a limiting end face 37. The limiting end face 37 contacts the pressing rod 20, so that the pressing rod 20 is kept in a pressing state.

[0058] In this embodiment, a spatial four-bar self-balancing system is formed by a three-stage hinge linkage mechanism consisting of a movable frame 33, a connecting plate 38, and a movable seat 30. When the operating force is applied by moving the rubber sleeve 35, the limiting end face 37 and the lower pressure rod 20 generate a contact torque, so that the lower pressure rod 20 achieves bidirectional torque balance locking.

[0059] 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.
