DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Example 1: Please refer to Figure 1 to Figure 3 A clamping device for welding automobile parts comprises a base 1, a support frame 2 and a fixing frame 3 are fixedly mounted on the top surface of the base 1 by bolts, and the fixing frame 3 is located on one side of the support frame 2, a main control box 4 is fixedly mounted on the outer wall of the support frame 2, a laser welding structure for welding parts is fixedly mounted on one side of the support frame 2 close to the fixing frame 3, and a clamping structure for fixing parts is fixedly mounted on the upper surface of the fixing frame 3;

[0032] The laser welding structure includes a mechanical arm 501, which is located at one side of the support frame 2. A laser welding machine 502 is fixedly installed at one end of the mechanical arm 501, and a laser welding head 503 is fixedly installed at the bottom end of the laser welding machine 502. A laser emitter for assisting positioning welding is installed on the outer wall of the laser welding head 503. The laser emitter emits a light spot to align with the welding starting point, and the laser welding machine 502 is started to weld. During the welding process, the welding position is adjusted in real time according to the light spot.

[0033] The clamping structure includes a fixing seat 601, which is located on the top surface of the fixing frame 3. A fixing ring 602 is fixedly sleeved on the outer wall of the fixing seat 601. A flip ring 603 is rotatably installed on the outer wall of the fixing ring 602 through a pin. A plurality of steel wire ropes 604 for fixing parts are installed on the outer wall of the flip ring 603. By rotating the flip ring 603, the plurality of steel wire ropes 604 are covered on the parts. The parts are bound and fixed by utilizing the flexibility and adjustability of the steel wire ropes 604, thereby realizing the clamping and positioning of the parts.

[0034] Specifically, the outer wall of the support frame 2 is fixedly installed with a mounting plate 7 for positioning the mechanical arm 501 by bolts, and the mechanical arm 501 is fixedly installed on the top surface of the mounting plate 7, and the bottom surface of the base 1 is fixedly installed with an adjustment seat 8 for adjusting the horizontal state of the device by bolts. The adjustment seat 8 can keep the base 1 in a horizontal state by adjusting its own height according to the ground conditions, thereby ensuring the stable placement of the entire device, avoiding the loose fixation of parts due to tilting, and affecting the welding quality by displacement during the welding process, providing a stable foundation for the laser welding head 503 to perform precise welding operations, ensuring welding accuracy, and enabling the device to adapt to various complex working scenes, effectively improving the welding quality and production efficiency of automotive parts;

[0035] More specifically, the steel wire rope 604 is a rope of ceramic fiber reinforced composite steel wire, which utilizes the extremely low thermal conductivity and high melting point of ceramic fiber to effectively block heat conduction and reduce the impact on the steel wire rope 604 during welding;

[0036] One end of each steel wire rope 604 away from the flip ring 603 is provided with a storage structure for winding up the steel wire rope 604, and the storage structure is arranged on the outer wall of the fixing ring 602. The other end of each steel wire rope 604 is clamped with a buckle structure for fixing the steel wire rope 604, and the buckle structure is fixedly installed on the outer wall of the flip ring 603.

[0037] See also Figure 2 to Figure 4 The storage structure includes an outer cover 605, the inner cavity of the outer cover 605 is plugged with a fixed shaft 606, and the fixed shaft 606 is fixedly connected to the outer wall of the fixed ring 602, and the inner cavity of the outer cover 605 is rotatably installed with a winding roller 607 for storing the steel wire rope 604, and one end of the steel wire rope 604 is wound around the outer wall of the winding roller 607;

[0038] Specifically, by rotating the flip ring 603, the steel wire rope 604 is stretched to drive the winding roller 607 to rotate. A torsion spring 608 is fixedly installed on the inner wall of the winding roller 607, and one end of the torsion spring 608 is fixedly connected to the outer wall of the fixed shaft 606. The torsion spring 608 enables the winding roller 607 to be reset, so that the steel wire rope 604 can be freely retracted and released, saving operation time.

[0039] A positioning bolt 609 for positioning the deployed wire rope 604 is fixedly mounted on the top surface of the outer cover 605, and a positioning groove is provided in the inner cavity of the positioning bolt 609, and a nut 610 is threadedly sleeved on the outer wall of the positioning bolt 609;

[0040] Specifically, when one end of the steel wire 604 passes through the outer cover 605 and is inserted into the positioning groove (the outer diameter of the steel wire 604 is larger than the inner diameter of the positioning groove) and is inserted into the positioning bolt 609, during the insertion process, the steel wire 604 generates a uniform and outward extrusion force on the inner wall of the positioning groove. The positioning groove is squeezed by the steel wire 604, which causes the positioning groove to expand outward, thereby allowing the end of the positioning bolt 609 close to the nut 610 to be stretched outward. At this time, the nut 610 is rotated to move along the positioning bolt 609, driving the positioning groove to gradually shrink, thereby tightly clamping the steel wire 604, achieving the effect of firmly fixing the steel wire 604, and can stably constrain the clamped parts to prevent the steel wire 604 from loosening during the processing process, providing a solid guarantee for the high-quality welding of automotive parts.

[0041] More specifically, the positioning bolt 609 is made of alloy structural steel, which has a certain toughness and can avoid brittle fracture when subjected to force;

[0042] A sawtooth ring 1 611 is fixedly installed on one side of the winding roller 607, and the sawtooth ring 1 611 is used to further prevent the winding roller 607 from rotating at will. The outer wall sliding sleeve of the positioning bolt 609 is provided with a sliding plate 612, and the bottom end of the sliding plate 612 passes through the outer cover 605 and is fixedly installed with a sawtooth ring 2 613, and the sawtooth ring 2 613 is meshed with the sawtooth ring 1 611;

[0043] Specifically, the sliding plate 612 is located at one side of the nut 610. When the nut 610 is rotated, the sliding plate 612 is pushed to move, thereby driving the second sawtooth ring 613 to approach the first sawtooth ring 611 and engage with it to limit the rotation of the winding roller 607. At the same time, a reset spring 614 is fixedly installed on the inner wall of the outer cover 605, and the reset spring 614 is fixedly connected to the second sawtooth ring 613. When the nut 610 moves in the reverse direction, the reset spring 614 pulls the second sawtooth ring 613 to retract and reset, thereby separating it from the first sawtooth ring 611, and releasing the restriction on the winding roller 607.

[0044] More specifically, the outer wall of the outer cover 605 is provided with a sliding groove for providing movement of the sliding plate 612 , and the sliding plate 612 is located in the sliding groove.

[0045] See also Figure 4 The snap-on structure includes a fixed block 615, which is provided with multiple fixed blocks 615 and fixedly installed on the outer wall of the flip ring 603. One side of each fixed block 615 is rotatably connected to a fixing buckle 616 for fixing the steel wire rope 604 through a pin shaft, and the fixing buckle 616 is snapped on the outer wall of the fixed block 615. One end of each steel wire rope 604 away from the outer cover 605 is sleeved on the outer wall of the fixed block 615.

[0046] See also Figure 3 The outer surface of the flip ring 603 is fixedly installed with a plurality of blocks 617 for positioning the flip ring 603, and the outer wall of the fixed ring 602 is fixedly installed with a plurality of slot blocks 618. The inner cavity of each slot block 618 is provided with a slot for clamping the block 617, and each block 617 is clamped with the slot after the flip ring 603 is rotated. When the weld is blocked by the steel wire rope 604, the connection between the steel wire rope 604 and the fixed block 615 can be released by flipping the fixing buckle 616 of the corresponding steel wire rope 604, so as to expose the weld, provide a clear and unobstructed operating area for subsequent welding work, and effectively avoid welding inconvenience and quality risks caused by the obstruction of the steel wire rope 604.

[0047] Example 2: Please refer to Figure 1-2 , Figure 5, a clamping device for welding automobile parts, which is different from the embodiment 1 in that an operating plate 619 is fixedly mounted on the inner wall of the fixing seat 601, an auxiliary structure for further pulling the wire rope 604 to fix the parts is fixedly mounted on the upper surface of the operating plate 619, and an opening and closing structure for facilitating the replacement of parts is rotatably mounted on the bottom surface of the operating plate 619;

[0048] The auxiliary structure includes a positioning seat 901, which is provided with a plurality of positioning seats 901 and fixedly mounted on the upper end of the operating plate 619. Each positioning seat 901 is threadedly connected with an adjusting bolt 902, and the top of the adjusting bolt 902 is rotatably connected with a hook 903 for hooking the wire rope 604 through a bearing.

[0049] Specifically, the hook 903 is clamped with the wire rope 604, and the inner cavity of the positioning seat 901 is provided with a movable cavity for raising and lowering the adjustment bolt 902. By rotating the adjustment bolt 902, the hook 903 is driven to pull the wire rope 604 to gradually move downward, so as to better fit the parts, enhance the clamping effect, and avoid loosening of the parts.

[0050] Example 3: Please refer to Figure 6-7 , a clamping device for welding automobile parts, which is different from Example 1 in that the opening and closing structure includes a driving ring 101, which is rotatably installed inside the outer cover 605, and the bottom end of the driving ring 101 is rotatably connected to a plurality of transmission rods 102 through a pin shaft, and one end of each transmission rod 102 is rotatably connected to an opening and closing plate 103 through a pin shaft, and the top surface of the opening and closing plate 103 is rotatably connected to the operating plate 619 through a pin shaft;

[0051] Specifically, a center groove is opened at the center of the operation plate 619, and the opening and closing of the center groove is changed by rotating the multiple opening and closing plates 103;

[0052] More specifically, a gear sleeve 104 for driving the driving ring 101 to rotate is fixedly installed at the bottom end of the driving ring 101, and a supporting plate for supporting the gear sleeve 104 is fixedly installed in the inner cavity of the outer cover 605. A motor 105 is fixedly installed on the inner wall of the outer cover 605 through a connecting plate. A gear 106 is fixedly installed on the output shaft of the motor 105, and the gear 106 is meshed with the gear sleeve 104. The motor 105 drives the gear 106 to rotate, so that the gear sleeve 104 drives the driving ring 101 to rotate accordingly, thereby controlling the multiple transmission rods 1 02 drives the opening and closing plate 103 to rotate around the pin connected to the operating plate 619. The rotation of multiple opening and closing plates 103 opens the center groove at the center of the operating plate 619, so that the parts placed on the operating plate 619 fall downward, so that the parts can be replaced without removing the restriction of the wire rope 604. There is no need to adjust the tightness of the wire rope 604 again, which reduces the operation steps and avoids the errors that may be introduced by repeatedly adjusting the tightness of the wire rope 604, effectively improving the overall production efficiency and ensuring the efficiency and stability of the production process;

[0053] See also Figure 2 , Figure 6 An electric push rod 11 is fixedly installed in the inner cavity of the fixed seat 601, and the bottom end of the electric push rod 11 is fixedly connected to the upper surface of the fixed frame 3, and a material plate 12 for supporting parts is fixedly installed on the top of the electric push rod 11. An opening groove for taking parts is opened on one side of the fixed seat 601, and a sensor for detecting whether the opening and closing plate 103 supports the parts is installed on one side of the material plate 12. The material plate 12 is driven by the electric push rod 11 to rise and catch the parts, so that they can be taken out from the opening groove later.

[0054] The working principle of the present invention is:

[0055] First, place a group of parts to be welded in the center groove on the operating plate 619, support the parts through the opening and closing plate 103, rotate the flip ring 603, insert each clamp block 617 into the slot block 618, so that the wire rope 604 fully covers the parts, and use the flexibility and adjustability of the wire rope 604 to bind and fix the connection;

[0056] When the steel wire rope 604 blocks the weld, the connection between the steel wire rope 604 and the fixing block 615 is released by flipping the fixing buckle 616 corresponding to the steel wire rope 604, and the winding roller 607 is driven to rotate by the torsion spring 608, thereby retracting the steel wire rope 604 to expose the weld of the part;

[0057] Then, the steel wire rope 604 is inserted into the positioning bolt 609, and the nut 610 is rotated to move along the positioning bolt 609, so that the positioning bolt 609 clamps the steel wire rope 604 to prevent the steel wire rope 604 from loosening. At the same time, when the nut 610 moves, the sliding plate 612 is pushed to drive the sawtooth ring 2 613 to mesh with the sawtooth ring 1 611, thereby limiting the rotation of the winding roller 607, so as to further strengthen the fixation of the steel wire rope 604;

[0058] At the same time, the adjusting bolt 902 is rotated to drive the hook 903 to pull the wire rope 604 downward to further fit the parts and enhance the clamping effect;

[0059] Then the robot arm 501 drives the laser welding machine 502 to move to the weld, and the laser emitter emits a light spot. The laser welding head 503 is aligned with the welding starting point according to the light spot, and is ready for welding.

[0060] Finally, when the parts need to be replaced, the motor 105 is started to drive the gear 106 to rotate, and the gear sleeve 104 meshing with the gear 106 drives the drive ring 101 to rotate. The drive ring 101 drives the opening and closing plate 103 to rotate around the pin connected to the operating plate 619 through the transmission rod 102, so that the center groove at the center of the operating plate 619 opens, and the parts placed on the operating plate 619 fall down, and the electric push rod 11 drives the material plate 12 to rise and catch the parts, so that they can be taken out from the open groove later, and then new parts are placed on the material plate 12, cooperate with the electric push rod 11 to move the part up to the center groove, and control the drive ring 101 to rotate in the opposite direction through the motor 105, so that the multiple opening and closing plates 103 are gradually merged. When the opening and closing plates 103 contact the parts and support the parts from the bottom, the sensor detects that the opening and closing plates 103 have supported the parts, and the material plate 12 is driven by the electric push rod 11 to move down and reset, so that when welding the same type of parts, there is no need to adjust the wire rope 604 again, and new parts can be replaced, thereby reducing operating steps and errors and improving production efficiency.

[0061] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed in the present invention, which should be covered by the protection scope of the present invention.
