Technical Field

[0001] This invention relates to the field of welding technology, specifically to a laser welding device for producing metal matrix composite materials. Background Technology

[0002] Metal matrix composites are composite materials composed of a metal matrix and reinforcing phases such as ceramic particles and long fibers. They possess excellent mechanical properties, high temperature resistance, wear resistance, and high thermal conductivity and strength. Due to these characteristics, metal matrix composites are widely used in aerospace, automotive, electronics, and other high-tech fields.

[0003] Chinese patent CN119368926A, authorized and published on January 28, 2025, discloses a laser welding device for producing metal matrix composites. The device includes a welding table with symmetrically arranged supports on its top. A laser welding machine is positioned between two sets of supports. The positioning and clamping assembly includes first movable slots symmetrically formed on the top of the welding table. A strip frame is fixedly connected to the top of the movable block. Two sets of movable blocks are arranged on the top of the welding table, and both sets of movable blocks are simultaneously movably connected to the two sets of strip frames. A clamping block is arranged on one side of each movable block, and the clamping block is simultaneously movably connected to the two sets of strip frames. A connecting rod is hinged between the strip frame and the movable block via a hinge.

[0004] In the aforementioned application documents, clamps are used to fix the material before a laser welding device is used for welding. However, when the welding head moves rapidly, there is a possibility that the material in contact with the welding head may not be stable enough, thus affecting the welding effect of the device.

[0036] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0037] Example 1, please refer to Figures 1-5 A laser welding apparatus for producing metal matrix composites, comprising:

[0038] The welding table 100 has a lead screw 200 driven by a servo motor rotatably connected inside it, and a movable seat 300 is mounted on the outside of the lead screw 200.

[0039] An electric slide table 400 is mounted on a movable base 300, and a laser welding machine 500 driven by an electric telescopic rod is mounted on the side of the electric slide table 400.

[0040] A fixing block 601 is mounted on the top of the welding table 100. A sliding block 603 is connected to the side of the fixing block 601 via a spring 602. A clamping plate 604 is fixedly connected to the side of the sliding block 603. Pulling the sliding block 603 upwards compresses the spring 602 and moves the clamping plate 604 upwards, placing the material between the clamping plate 604 and the welding table 100. Releasing the sliding block 603 allows it to reset under the action of the spring 602, thus initially clamping the material.

[0041] A pressing plate 605 is slidably connected to the side of the sliding block 603. An elastic telescopic rod 614 is assembled between the pressing plate 605 and the clamping plate 604. The lead screw 200 and the pressing plate 605 are connected by a transmission component, which includes a hydraulic chamber 606 assembled on the outside of the lead screw 200. After the material is initially clamped, the electric telescopic rod is started, which drives the laser welding machine 500 to move downward. Then, the laser welding machine 500, the electric slide table 400, and the servo motor are started, thereby driving the laser welding machine 500 to perform the corresponding welding operation. When the laser welding machine 500 moves rapidly along the direction of the lead screw 200, the lead screw 200 is in a state of rapid rotation, which drives the hydraulic chamber 606 assembled on the outside of the lead screw 200 to rotate rapidly.

[0042] The inner wall of hydraulic chamber 606 is slidably connected to a sliding plate 608 via an elastic telescopic rod 607, and an arc-shaped plate 609 is slidably connected to the side of hydraulic chamber 606. When hydraulic chamber 606 rotates rapidly, the sliding plate 608 inside hydraulic chamber 606, under the action of centrifugal force, squeezes the oil inside hydraulic chamber 606, causing the oil to move towards the side closer to the arc-shaped plate 609, thereby driving the arc-shaped plate 609 to move. At this time, the arc-shaped plate 609 extends synchronously while rotating.

[0043] The welding table 100 and the fixing block 601 are equipped with a hydraulic device 610. The hydraulic device 610 consists of two rigid chambers and a hose. The rigid chambers and the hose are filled with oil. One end of the hydraulic device 610 is slidably connected to a force rod 611, and the other end of the hydraulic device 610 is slidably connected to a transmission rod 612. The force rod 611 is located at the top of the arc plate 609 and is in contact with the arc plate 609. The transmission rod 612 is located at the top of the extrusion plate 605 and is fixed to the extrusion plate 605. When the arc-shaped plate 609 extends synchronously while rotating, it squeezes the force-bearing rod 611, causing it to move upwards. At this time, the force-bearing rod 611 squeezes the oil in the hydraulic device 610, causing the oil to move closer to the transmission rod 612. This, in turn, causes the transmission rod 612 to move downwards. Simultaneously, the transmission rod 612 moves the pressing plate 605 downwards. Combined with the elastic telescopic rod 614, this applies an additional force to the clamping plate 604, further clamping the material. This improves the stability of the device under these conditions.

[0044] A spring 613 is fitted to the top of the force-bearing rod 611. After the corresponding welding operation is completed, the lead screw 200 stops rotating, and the hydraulic chamber 606 mounted on the outside of the lead screw 200 stops rotating, causing the centrifugal force acting on the sliding plate 608 to disappear. The sliding plate 608 can then be reset under the action of the elastic telescopic rod 607. Similarly, the arc plate 609 is reset. At this time, the effect of the arc plate 609 on the force-bearing rod 611 disappears, causing the force-bearing rod 611 to be reset under the action of the spring 613. Similarly, the transmission rod 612 is reset, so as to facilitate the next use of the device.

[0045] The side of the movable base 300 is equipped with a heat dissipation component 700 for heat dissipation, and the top of the welding table 100 is equipped with a tool storage component 800.

[0046] In use, pull the sliding block 603 upwards, causing it to compress the spring 602 and move the clamping plate 604, which is fixedly connected to it, upwards. Place the material between the clamping plate 604 and the welding table 100. Release the sliding block 603, allowing it to reset under the action of the spring 602, thus initially clamping the material. Start the electric telescopic rod, which moves the laser welding machine 500 downwards. Then start the laser welding machine 500, the electric slide table 400, and the servo motor, thereby driving the laser welding machine... 500 performs the corresponding welding operation; when the laser welding machine 500 moves rapidly along the direction of the lead screw 200, the lead screw 200 is in a state of rapid rotation, which drives the hydraulic chamber 606 assembled on the outside of the lead screw 200 to rotate rapidly. Under the action of centrifugal force, the sliding plate 608 in the hydraulic chamber 606 squeezes the oil in the hydraulic chamber 606, causing the oil to move towards the side closer to the arc plate 609, thereby causing the arc plate 609 to move. At this time, the arc plate 609 is in a state of rotation. Simultaneous extension compresses the force-bearing rod 611, causing it to move upwards. This force-bearing rod 611 then compresses the oil within the hydraulic device 610, causing it to move closer to the transmission rod 612. This, in turn, causes the transmission rod 612 to move downwards. Simultaneously, the transmission rod 612 moves the extrusion plate 605 downwards. Combined with the elastic telescopic rod 614, this applies an additional force to the clamping plate 604, further clamping the material. After the corresponding welding operation is completed, the lead screw 200 stops rotating, and the hydraulic chamber 606 mounted on the outside of the lead screw 200 stops rotating, so that the centrifugal force acting on the sliding plate 608 disappears, and the sliding plate 608 can be reset under the action of the elastic telescopic rod 607. Similarly, the arc plate 609 is reset. At this time, the effect of the arc plate 609 on the force rod 611 disappears, so the force rod 611 is reset under the action of the spring 613. Similarly, the transmission rod 612 is reset.

[0047] Example 2, please refer to Figures 1-8Based on Embodiment 1, the heat dissipation assembly 700 includes a second hydraulic device 701 mounted on the top of the first hydraulic device 610 and the side of the movable seat 300. The second hydraulic device 701 consists of a rigid chamber and a flexible hose. The second hydraulic device 701 is located at the top of the first hydraulic device 610 and is in communication with the first hydraulic device 610. The interior of the rigid chamber and the flexible hose is filled with oil. A toothed rod 702 is slidably connected to the bottom of the second hydraulic device 701. A connecting plate 703 and a cooling fan 704 are respectively mounted on the side of the electric slide table 400. After the welding operation is completed, the cooling fan 704 is started to perform the corresponding cooling operation. At the same time, the moving seat 300 and the electric slide table 400 are driven to move quickly to cool different welding parts of the material. The rapid movement of the moving seat 300 causes the oil in the hydraulic device 610 to be squeezed and move. Some of the oil in the hydraulic device 610 can then move to the hydraulic device 701 connected to it, thereby pushing the oil in the hydraulic device 701 to move towards the side closer to the rack 702.

[0048] A through-type transmission rod 705 is rotatably connected inside the connecting plate 703. A gear 706 is fixedly connected to the side of the transmission rod 705, and a guide plate 707 is fixedly connected to the outer side of the transmission rod 705. When the rack 702 is squeezed by oil, it moves downward to the gear 706 and meshes with it. The rapidly moving electric slide 400 drives the connecting plate 703, which is fixedly connected to it, to move. This causes the connecting plate 703 to synchronously drive the gear 706 to move horizontally. At this time, the gear 706 is restricted by the meshing rack 702, causing it to rotate while moving. The gear 706 then drives the transmission rod 705, which is fixedly connected to it, to rotate. This causes the transmission rod 705 to drive the guide plate 707, which is fixedly connected to it, to rotate, thereby guiding the cool air blown out by the cooling fan 704. This improves the cooling effect of the device.

[0049] In use, based on Example 1, after the welding operation is completed, the cooling fan 704 is started to perform the corresponding cooling operation, and at the same time, the movable seat 300 and the electric slide table 400 are driven to move rapidly to cool different welding parts of the material. The rapid movement of the movable seat 300 causes the oil in the hydraulic device 1 610 to be squeezed and move, so that part of the oil in the hydraulic device 1 610 can move to the hydraulic device 2 701 connected to it, thereby pushing the oil in the hydraulic device 2 701, causing the oil in the hydraulic device 2 701 to move towards the side closer to the rack 702. The rack 702 is subjected to The oil is squeezed and moves downward to gear 706 and meshes with it. The rapidly moving electric slide 400 drives the connecting plate 703, which is fixedly connected to it, to move. This causes the connecting plate 703 to drive the gear 706 to move horizontally. At this time, the gear 706 is restricted by the gear rack 702 that it meshes with, so that the gear 706 rotates while moving. The gear 706 then drives the transmission rod 705, which is fixedly connected to it, to rotate. This causes the transmission rod 705 to drive the guide plate 707, which is fixedly connected to it, to rotate, so as to guide the cold air blown out by the cooling fan 704.

[0050] Example 3, please refer to Figures 1-10 Based on Embodiment 1 and Embodiment 2, the placement component 800 includes a hydraulic chamber 2 801 mounted on the side of the hydraulic device 1 610. The top of the welding table 100 is provided with a storage groove 802. The top of the welding table 100 is rotatably connected to a rotating shaft 803. A baffle 804 and a force plate 806 are fixedly connected to the outside of the rotating shaft 803. A connecting rod 805 is slidably connected to the side of the hydraulic chamber 2 801. The connecting rod 805 is located at the top of the force plate 806 and is fixed to the force plate 806. The connecting rod 805 is slidably connected to the side of the hydraulic chamber 2 801. When the oil in hydraulic chamber 801 moves towards the connecting rod 805, the connecting rod 805 is compressed by the oil and moves, causing the force plate 806, which is fixedly connected to the connecting rod 805, to rotate. This force plate 806 then drives the rotating shaft 803, which is fixedly connected to it, to rotate. The rotating shaft 803 then drives the baffle 804, which is fixedly connected to it, to rotate to the top position of the storage slot 802, thus closing the storage slot 802. This improves the protective effect of the device on items inside the storage slot 802 during welding operations.

[0051] Similarly, when the device is reset, the pressure inside the hydraulic chamber 801 decreases, causing the baffle 804 to reset and reopen the storage slot 802. This facilitates the placement of components for the next use.

[0052] In use, based on Embodiments 1 and 2, some small welding materials or tools are placed in the storage tank 802 for storage. When the device performs welding operations, the oil in the hydraulic device 1 610 moves, and some of the oil moves to the hydraulic chamber 2 801 connected to the hydraulic device 1 610, pushing the oil in the hydraulic chamber 2 801 to move towards the side closer to the connecting rod 805. The connecting rod 805 moves due to the pressure of the oil, causing the force plate 806 fixedly connected to the connecting rod 805 to rotate. The force plate 806 drives the rotating shaft 803 fixedly connected to it to rotate, and the rotating shaft 803 drives the baffle 804 fixedly connected to it to rotate, so that the baffle 804 rotates to the top position of the storage tank 802, thereby closing the storage tank 802. Similarly, when the device is reset, the pressure in the hydraulic chamber 2 801 decreases, so that the baffle 804 resets and reopens the storage tank 802.

[0053] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
