Description

[0002] In the field of mechanical manufacturing, the welding quality of metal materials directly affects the performance and service life of the product. Traditional metal welding methods have problems such as low efficiency and unstable quality. However, laser welding machines, with their advantages such as high energy density, high precision, and small heat-affected zone, have gradually become the mainstream equipment for metal welding.

[0003] However, existing laser welding machines for metal materials still have some shortcomings. On the one hand, the clamping position of some laser welding machines is fixed, and they can only weld materials of specific length specifications, which cannot adapt to the diverse material demands in the market. This means that during the production process, companies need to equip themselves with a variety of welding equipment of different specifications, which increases production costs and equipment management difficulties. On the other hand, for the welding of special-shaped materials or curved materials, the existing clamping method is difficult to provide stable fixation, and it is easy for the material to shift during the welding process, thereby affecting the welding quality and increasing the defective rate of the product.

A clamping mechanism is detachably installed on one end of the pushing mechanism, and an auxiliary clamping mechanism is fixed on the other side of the upper end of the carrying plate 9, which can adapt to metal materials of different lengths and specifications. Through the movable carrying plate 9 and the flexible clamping mechanism, the welding needs of various materials are met, and the production cost is reduced;

[0038] A mounting plate 28 is fixed to the lower end of the guide rail 2. The lower end of the mounting plate 28 is fixed to the upper end of the base plate 4 by multiple screws 27. The two track wheels 11 on the same side are clamped to one guide rail 2 on the same side, ensuring the stability and reliability of the connection between the guide rail 2 and the base plate 4, and preventing the guide rail 2 from loosening or shifting during the operation of the equipment, thereby affecting the accuracy of the entire welding process.

[0039] The clamping mechanism includes a carrier box 26 fixed to the lower end of the carrier plate 9. Two cylinders 13 are fixed to one side of the carrier box 26. The end of the piston rod of the cylinder 13 is fixed with an insert block 12. A plurality of slots 3 are provided on both sides of the upper end of the bottom plate 4 at equal intervals. An insert block 12 on the same side is inserted into a slot 3 on the same side. When the carrier plate 9 is moved to the appropriate position, the cylinder 13 is started to push the insert block 12 into the slot 3 to achieve the clamping and fixing of the carrier plate 9. The clamping method can effectively prevent the position of the carrier plate 9 from being offset during the welding process, thereby ensuring the accuracy and quality of the welding.

[0040] A cavity is provided in the carrier box 26 , and a first servo motor 14 is installed on one side of the cavity. The output shaft of the first servo motor 14 is connected to one side of the track wheel 11 to drive the track wheel 11 to move to a corresponding position;

The setting of the reduction box 30 can adjust the speed of the screw 18 according to different welding requirements, thereby controlling the moving speed of the pushing mechanism and improving the flexibility and applicability of the equipment;

[0042] The pushing mechanism includes four guide rods 17 fixed to one side of the connecting plate 16, one end of the four guide rods 17 is commonly connected to one side of the fixed box 22, and a moving block 15 is threadedly screwed on the screw 18.

One end of the four rotating rods 21 is commonly rotatably connected to a movable block 24.

The guide rod 17 ensures the linearity and stability of the movement of the moving block 15. The rotating rod 21 between the moving block 15 and the fixed box 22 rotates accordingly, pushing the movable block 24 to move, and then driving the parts connected to the movable block 24 to move, thereby realizing the clamping action of the metal material;

[0045] When laser welding is performed in the present invention:

[0046] 1. Material placement: Place the metal material to be welded on the carrier plate 9. The carrier plate 9 serves as a support platform for the material and provides a stable foundation for subsequent welding operations.

The moving block 15 on the screw 18 moves along the screw 18 under the guidance of the guide rod 17. The rotating rod 21 between the moving block 15 and the fixed box 22 rotates accordingly, pushing the movable block 24 to move, and then driving the movable plate 10 to move. The first stud 20 and the second stud 25 on the movable plate 10 respectively drive the second clamping plate 7 to move, and cooperate with the first clamping plate 6 on the fixed plate 5 to achieve stable clamping of the metal material.

[0048] 3. Position adjustment: The first servo motor 14 drives the track wheel 11 to move on the guide rail 2, thereby realizing the movement of the carrier plate 9 and accurately positioning the welding position.
