Description

Technical Field

[0001] This utility model relates to the field of welding processing technology, specifically to an adjustable laser welding positioning and clamping fixture. Background Technology

[0002] Laser welding uses an optical system to focus a laser beam, generating extremely high temperatures at the focal point of the workpiece, instantly melting the materials to be welded. The materials then rapidly cool and solidify, achieving atomic bonding.

[0003] A published Chinese patent, publication number CN207057913U, discloses a positioning and clamping device for welded parts in laser welding, belonging to the field of laser welding technology. The positioning and clamping device includes a welding platform. The mounting beam of the welded part is fixed to the welding platform by a horizontal limiting block, a vertical limiting block, a clamping block, and a positioning block. A side plate is fixed to the mounting beam and clamped by a pressure plate, which is then further clamped by a vertical clamp. A support rod is vertically fixed to the welding platform, with its upper end resting against the lower surface of the side to prevent deformation. However, the positioning and clamping mechanism of this patent cannot be flexibly adjusted during laser welding.

[0026] To enable those skilled in the art to better understand the present invention, the solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0027] This utility model provides a technical solution: an adjustable laser welding positioning and clamping fixture, including a base 10, a processing area 20 on the base 10, and a workpiece 30 to be processed placed in the processing area 20;

[0028] Y-direction guide strips 11 and moving plates 12 are respectively provided on the left and right sides of the processing area 20 on the base 10. Both the Y-direction guide strips 11 and the moving plates 12 are equipped with clamping mechanisms 40. X-direction guide strips 13 distributed along the X-axis are provided on one side of the moving plates 12. The moving plates 12 are adjustablely matched with the Y-direction guide strips 11 with the X-direction guide strips 13 as guides.

[0029] Two sets of side pressing mechanisms 50 are provided on the base 10 on the front and rear sides of the processing area 20. The side pressing mechanisms 50 are adjustable relative to the base 10 by bolts. The two sets of side pressing mechanisms 50 are used to press the workpiece 30 from the front and rear sides in an adjustable manner.

[0030] The base 10 has Y-axis positioning blocks 14 on both sides of the side pressing mechanism 50 on one side. The Y-axis positioning blocks 14 can be adjusted relative to the base 10 by bolts.

[0031] Through this technical solution, the clamping mechanism 40 on the moving plate 12 can move closer to the left clamping mechanism 40 along the X-direction guide bar 13. The distance between the left and right clamping mechanisms 40 in the X-axis direction can be adjusted according to the width of the workpiece 30 to be processed, so as to adapt to workpieces 30 of different widths. The side pressing mechanisms 50 on the front and rear sides can be adjusted relative to the base 10 by bolts to adapt to workpieces 30 of different lengths. The Y-direction positioning block 14 can also be adjusted by bolts, providing a stable Y-direction reference for the workpiece 30. The left and right clamping mechanisms 40 and the front and rear side pressing mechanisms 50 clamp and fix the workpiece 30 from multiple directions, effectively avoiding welding deviation caused by the displacement of the workpiece 30 during the welding process.

[0032] Furthermore, the two sets of clamping mechanisms 40 have the same structure, each including several sets of first mounting seats 41 and first pressing members 42. The first mounting seat 41 is provided with an arc-shaped surface 411 that fits the workpiece 30, and the first pressing member 42 is mounted on the first mounting seat 41.

[0033] Through this technical solution, the arc-shaped surface 411 of the first mounting base 41 can better fit with the surface of the workpiece 30, which can increase the contact area, reduce local stress concentration, and prevent the workpiece 30 from deforming during the clamping process.

[0034] Furthermore, the two sets of side pressing mechanisms 50 have the same structure, both including a second mounting base 51 and a second pressing member 52, with the second pressing member 52 mounted on the second mounting base 51.

[0035] Through this technical solution, the second mounting base 51 provides a stable mounting foundation for the second pressing component 52, ensuring that the second pressing component 52 can accurately act on the front and rear sides of the workpiece 30, and cooperate with the pressing mechanism 40 on the left and right sides and the Y-direction positioning block 14 to achieve comprehensive fixation of the workpiece 30 from multiple directions.

[0036] Furthermore, the movable plate 12 is provided with a Y-direction guide groove 121, and the first mounting base 41 of the clamping mechanism 40 is provided with a fixing groove 412. The fixing groove 412 on the side closer to the movable plate 12 can be adjusted relative to the Y-direction guide groove 121 by bolts, and the fixing groove 412 on the side away from the movable plate 12 can be adjusted relative to the base 10 by bolts.

[0037] With this technical solution, the Y-direction guide groove 121 of the movable plate 12 cooperates with the fixing groove 412 of the first mounting seat 41, so that the first mounting seat 41 on the movable plate 12 can move along the Y-direction guide groove 121 and be fixed by bolts, and the first mounting seat 41 on the other side can move along the Y-direction guide bar 11 and be fixed by bolts, thereby realizing the position adjustment of the pressing mechanism 40 in the Y direction.

[0038] Furthermore, the first pressing member 42 includes a first fixed base 421 and a fixed arm 422 connected to the first fixed base 421. A first control arm 423 is hinged to the middle of the fixed arm 422. A first lever arm 424 is hinged to the middle of the first control arm 423. A second lever arm 425 is hinged to the end of the first lever arm 424 away from the first control arm 423. One end of the second lever arm 425 is hinged to the fixed arm 422. The other end of the second lever arm 425 is adjustablely connected to the pressing block mechanism 60.

[0039] Through this technical solution, the first pressing component 42 adopts a multi-stage lever structure consisting of a first control arm 423, a first lever arm 424, and a second lever arm 425. By raising or lowering the first control arm 423, the pressing block mechanism 60 is driven to press down on the workpiece 30 or release the workpiece 30, thereby quickly completing the clamping and disassembly of the workpiece 30.

[0040] Furthermore, the second pressing member 52 includes a second fixed base 521. A third lever arm 522 and a fourth lever arm 523 are hinged to both sides of the second fixed base 521. A second control arm 524 is hinged to the end of the third lever arm 522 away from the second fixed base 521. One end of the second control arm 524 is hinged to the fourth lever arm 523. A pressing block mechanism 60 is adjustablely connected to the end of the fourth lever arm 523 away from the second control arm 524.

[0041] With this technical solution, when the second control arm 524 is operated, the force can be transmitted to the pressing mechanism 60 through the linkage of the third lever arm 522 and the fourth lever arm 523, so as to quickly complete the clamping and disassembly of the workpiece 30, and the operation is simple and labor-saving.

[0042] Furthermore, the two sets of pressing mechanisms 60 have the same structure, each including a retainer 61 that is relatively locked on both sides of the lever arm. A screw 62 is inserted through the retainer 61 on both sides. Nuts 63 are connected to the outer surface of the retainer 61 on both sides of the screw 62. A pressing block 64 is connected to the end of the screw 62 away from the retainer 61.

[0043] This technical solution allows for quick adjustment of the position of the clamping seat 61 on the lever arm via the tightening nut 63, thereby adjusting the clamping position of the pressure block 64 relative to the workpiece 30 and meeting the adaptation requirements of different workpieces 30 in terms of local dimensions.

[0044] Furthermore, the base 10 is provided with pad strips 15 on both sides of the processing area 20 for supporting the workpiece 30.

[0045] Through this technical solution, the pad strip 15 provides a stable bearing base for the workpiece 30, avoiding shaking caused by insufficient flatness or impurities on the surface of the base 10 when the workpiece 30 is placed directly on the base 10.

[0046] Furthermore, the base 10 has lifting holes 16 at its four corners for hoisting.

[0047] With this technical solution, the lifting holes 16 at the four corners of the base 10 can be used with lifting equipment, so that the tooling 30 can be moved as a whole stably and efficiently.

[0048] Working principle: First, loosen the bolts to adjust the position of the Y-direction positioning block 14 on the base 10 to determine the reference positioning of the workpiece 30 in the Y direction. According to the length of the workpiece 30, loosen the bolts connecting the side pressing mechanism 50 and the base 10, adjust the distance between the two sets of side pressing mechanisms 50 in the front and back direction to adapt to the length of the workpiece 30, and then fix them again.

[0049] At the same time, the movable plate 12 is slid along the X-direction guide strip 13 to adjust the X-direction spacing of the left and right clamping mechanisms 40 to match the width of the workpiece 30, and then fixed with bolts;

[0050] Next, the workpiece 30 is placed on the pad strip 15 of the processing area 20, and one side of the workpiece 30 is attached to the Y-direction positioning block 14 to complete the initial Y-direction positioning.

[0051] Subsequently, in the left and right directions, the first mounting seat 41 on the movable plate 12 slides along the Y-direction guide groove 121, and the first mounting seat 41 on the other side moves along the Y-direction guide bar 11, so that the arc surface 411 fits against the side of the workpiece 30. Then, the first mounting seat 41 is fixed by bolts, and the first control arm 423 of the first pressing member 42 and the second control arm 524 of the second pressing member 52 are operated. Using the lever arm hinge structure, the pressing block mechanism 60 presses the workpiece 30.

[0052] During the clamping process, the pressure block mechanism 60 can adjust the position of the card seat 61 on the lever arm by adjusting the tightness nut 63, thereby adjusting the position of the pressure block 64 to ensure that the pressure block 64 is in close contact with the surface of the workpiece 30.

[0053] If it is necessary to change to workpieces of different specifications, loosen the fixing bolts of each mechanism, adjust the position of the Y-axis positioning block 14, the side pressing mechanism 50, the moving plate 12 and the pressing mechanism 40, and then achieve quick adaptation through the fine adjustment of the pressing block mechanism 60. After processing is completed, reverse the operation of the first control arm 423 and the second control arm 524, release the pressing block mechanism 60, and the workpiece 30 can be taken out.
