[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0021] Example 1, please refer to Figures 1 - 5 , a laser welding device for the production of metal matrix composites, including: Welding table 100, the inside of the welding table 100 is rotatably connected to a lead screw 200 driven by a servo motor, and a moving seat 300 is assembled on the outside of the lead screw 200; Electric sliding table 400, the electric sliding table 400 is assembled on the moving seat 300, and a laser welding machine 500 driven by an electric telescopic rod is assembled on the side of the electric sliding table 400; The top of the welding table 100 is equipped with a fixed block 601. The side of the fixed block 601 is connected with a sliding block 603 through a first spring 602. The side of the sliding block 603 is fixedly connected with a clamping plate 604. Pull the sliding block 603 upward, so that the sliding block 603 compresses the first spring 602 and drives the clamping plate 604 fixedly connected to it to move upward. Place the material between the clamping plate 604 and the welding table 100, and release the sliding block 603, so that the sliding block 603 is reset under the action of the first spring 602 to initially clamp the material.

[0022] The side of the sliding block 603 is slidably connected with an extrusion plate 605. An elastic telescopic rod 614 is assembled between the extrusion plate 605 and the clamping plate 604. The lead screw 200 and the extrusion plate 605 are connected through a transmission member. The transmission member includes a first hydraulic chamber 606 assembled on the outer side of the lead screw 200. After initially clamping the material, start the electric telescopic rod to drive the laser welding machine 500 to move downward, and then start the laser welding machine 500, the electric sliding table 400 and the servo motor, so as to drive the laser welding machine 500 to perform corresponding welding operations; when the laser welding machine 500 moves rapidly along the direction of the lead screw 200, at this time the lead screw 200 is in a state of rapid rotation, driving the first hydraulic chamber 606 assembled on the outer side of the lead screw 200 to rotate rapidly.

[0023] The inner wall of the first hydraulic chamber 606 is slidably connected with a sliding plate 608 through a second elastic telescopic rod 607. The side of the first hydraulic chamber 606 is slidably connected with an arc plate 609. When the first hydraulic chamber 606 rotates rapidly, the sliding plate 608 in the first hydraulic chamber 606 is under the action of centrifugal force, squeezing the oil in the first hydraulic chamber 606, so that the oil moves toward the side close to the arc plate 609, thereby driving the arc plate 609 to move. At this time, the arc plate 609 extends synchronously while rotating.

[0024] On the sides of the welding table 100 and the fixed block 601, a first hydraulic device 610 is assembled. The first hydraulic device 610 is composed of two sections of rigid bodies and one section of hose, and the interiors of the rigid bodies and the hose are filled with hydraulic oil. One end of the first hydraulic device 610 is slidably connected to a first force-bearing rod 611, and the other end of the first hydraulic device 610 is slidably connected to a first transmission rod 612. The first force-bearing rod 611 is located at the top of the arc-shaped plate 609 and is in contact with the arc-shaped plate 609. The first transmission rod 612 is located at the top of the extrusion plate 605 and is in a fixed state with the extrusion plate 605. When the arc-shaped plate 609 extends synchronously during rotation, it can extrude the first force-bearing rod 611, driving the first force-bearing rod 611 to move upward. At this time, the first force-bearing rod 611 can extrude the hydraulic oil in the first hydraulic device 610, causing the hydraulic oil in the first hydraulic device 610 to move toward the side close to the first transmission rod 612, thereby driving the first transmission rod 612 to move downward. The first transmission rod 612 synchronously drives the extrusion plate 605 to move downward. Cooperating with the first elastic telescopic rod 614, an additional force can be applied to the clamping plate 604 to complete further clamping of the material. The stability of the device during use in this situation is improved.

[0025] A second spring 613 is assembled on the top of the first force-bearing rod 611. After the corresponding welding operation is completed, the lead screw 200 stops rotating, and the first hydraulic chamber 606 assembled 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 second elastic telescopic rod 607. Similarly, the arc-shaped plate 609 is reset. At this time, the action of the arc-shaped plate 609 on the first force-bearing rod 611 disappears, causing the first force-bearing rod 611 to be reset under the action of the second spring 613. Similarly, the first transmission rod 612 is reset. This facilitates the next activation of the device.

[0026] A heat dissipation component 700 for heat dissipation is assembled on the side of the moving seat 300, and a placement component 800 for storing tools is assembled on the top of the welding table 100.

[0027] During use, pull the slider 603 upward, so that the slider 603 compresses the first spring 602 and drives the clamping plate 604 fixedly connected thereto to move upward. Place the material between the clamping plate 604 and the welding table 100, and release the slider 603, so that the slider 603 is reset under the action of the first spring 602 to initially clamp the material. Start the electric telescopic rod to drive the laser welding machine 500 to move downward, and then start the laser welding machine 500, the electric slide table 400 and the servo motor, so as to drive the laser welding machine 500 to perform corresponding welding operations; when the laser welding machine 500 moves rapidly along the direction of the lead screw 200, at this time, the lead screw 200 is in a state of rapid rotation, driving the hydraulic chamber 606 assembled outside the lead screw 200 to rotate rapidly. The sliding plate 608 in the hydraulic chamber 606 is under the action of centrifugal force, squeezing the oil in the hydraulic chamber 606, so that the oil moves toward the side close to the arc plate 609, thereby driving the arc plate 609 to move. At this time, the arc plate 609 extends synchronously while rotating, and can squeeze the first force receiving rod 611 to drive the first force receiving rod 611 to move upward. At this time, the first force receiving rod 611 can squeeze the oil in the hydraulic device 610, so that the oil in the hydraulic device 610 moves toward the side close to the first transmission rod 612, thereby driving the first transmission rod 612 to move downward. The first transmission rod 612 synchronously drives the pressing plate 605 to move downward, and cooperates with the first elastic telescopic rod 614 to apply an additional force to the clamping plate 604 to complete the further clamping of the material; after the corresponding welding operation is completed, the lead screw 200 stops rotating, and the hydraulic chamber 606 assembled outside 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 second elastic telescopic rod 607. Similarly, the arc plate 609 is reset. At this time, the action of the arc plate 609 on the first force receiving rod 611 disappears, so that the first force receiving rod 611 is reset under the action of the second spring 613. Similarly, the first transmission rod 612 is reset.

[0028] Embodiment 2. Please refer to Figures 1 - 8, on the basis of the first embodiment, the heat dissipation assembly 700 includes a second hydraulic device 701 assembled on the top of the first hydraulic device 610 and the side of the moving seat 300. The second hydraulic device 701 is composed of a section of rigid housing and a section of hose. The second hydraulic device 701 is located at the top of the first hydraulic device 610 and is in a communicating state with the first hydraulic device 610. The inside of the rigid housing and the hose is filled with hydraulic oil. A rack 702 is slidably connected to the bottom of the second hydraulic device 701. Connecting plates 703 and cooling fans 704 are respectively assembled on the side of the electric sliding table 400. After the welding operation is completed, the cooling fan 704 is started to perform corresponding cooling operations, and at the same time, the moving seat 300 and the electric sliding table 400 are driven to move quickly to cool different welding parts of the material. The fast-moving moving seat 300 causes the hydraulic oil in the first hydraulic device 610 to be squeezed and move, and part of the hydraulic oil in the first hydraulic device 610 can move into the second hydraulic device 701 connected to it, thereby pushing the hydraulic oil in the second hydraulic device 701 and causing the hydraulic oil in the second hydraulic device 701 to move toward the side close to the rack 702.

[0029] A transmission rod two 705 is rotatably connected to the inside of the connecting plate 703. A gear 706 is fixedly connected to the side of the transmission rod two 705. A deflector 707 is fixedly connected to the outside of the transmission rod two 705. When the rack 702 is squeezed by the hydraulic oil, it can move downward to the gear 706 and mesh with the gear 706. The fast-moving electric sliding table 400 drives the connecting plate 703 fixedly connected to it to move, so that the connecting plate 703 synchronously drives the gear 706 to move horizontally. At this time, the gear 706 is restricted by the rack 702 meshing with it, so that the gear 706 rotates while moving. The gear 706 then drives the transmission rod two 705 fixedly connected to it to rotate, so that the transmission rod two 705 drives the deflector 707 fixedly connected to it to rotate to deflect the cold air blown by the cooling fan 704. The cooling effect of the device is improved.

[0030] During use, based on the first embodiment, after completing the welding operation, start the cooling fan 704 to perform corresponding cooling operations. At the same time, drive the moving seat 300 and the electric slide table 400 to move quickly to cool different welded parts of the material. The quickly moving moving seat 300 causes the hydraulic oil in the first hydraulic device 610 to be squeezed and move, and part of the hydraulic oil in the first hydraulic device 610 can move to the second hydraulic device 701 connected to it, thereby pushing the hydraulic oil in the second hydraulic device 701, causing the hydraulic oil in the second hydraulic device 701 to move toward the side close to the rack 702. The rack 702 is squeezed by the hydraulic oil and can move downward to the gear 706 and mesh with the gear 706. The quickly moving electric slide table 400 drives the connecting plate 703 fixedly connected to it to move, causing the connecting plate 703 to drive the gear 706 to move horizontally synchronously. At this time, the gear 706 is restricted by the rack 702 meshing with it, causing the gear 706 to rotate while moving. The gear 706 then drives the second transmission rod 705 fixedly connected to it to rotate, causing the second transmission rod 705 to drive the deflector 707 fixedly connected to it to rotate to deflect the cold air blown by the cooling fan 704.

[0031] Embodiment 3, please refer to Figures 1 - 10 , based on the first and second embodiments, the placing assembly 800 includes a second hydraulic chamber 801 assembled on the side of the first hydraulic device 610. A receiving groove 802 is formed at the top of the welding table 100. A rotating shaft 803 is rotatably connected to the top of the welding table 100. A baffle 804 and a force-bearing plate 806 are fixedly connected to the outer side of the rotating shaft 803 respectively. A connecting rod 805 is slidably connected to the side of the second hydraulic chamber 801. The connecting rod 805 is located at the top of the force-bearing plate 806 and is fixed to the force-bearing plate 806. A connecting rod 805 is slidably connected to the side of the second hydraulic chamber 801. When the hydraulic oil in the second hydraulic chamber 801 moves toward the side close to the connecting rod 805, the connecting rod 805 is squeezed by the hydraulic oil and moves, driving the force-bearing plate 806 fixedly connected to the connecting rod 805 to rotate, causing the force-bearing plate 806 to drive 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, causing the baffle 804 to rotate to the top position of the receiving groove 802, thereby closing the receiving groove 802. During the welding operation, the protection effect of the device on the items in the receiving groove 802 is improved.

[0032] Similarly, when the device is reset, the pressure in the second hydraulic chamber 801 decreases, causing the baffle 804 to reset accordingly and reopen the receiving groove 802. Facilitating the next activation of the placing assembly.

[0033] In use, based on the first and second embodiments, some small welding materials or tools are placed in the storage groove 802 for storage. When the device performs welding operations, the oil in the first hydraulic device 610 moves, and part of the oil moves into the second hydraulic chamber 801 connected to the first hydraulic device 610, pushing the oil in the second hydraulic chamber 801, causing the oil in the second hydraulic chamber 801 to move towards the side close to the connecting rod 805. The connecting rod 805 moves due to the extrusion of the oil, driving the force-receiving plate 806 fixedly connected to the connecting rod 805 to rotate, causing the force-receiving plate 806 to drive 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 groove 802, thereby closing the storage groove 802. Similarly, when the device is reset, the pressure in the second hydraulic chamber 801 decreases, causing the baffle 804 to reset accordingly and reopen the storage groove 802.
