[0043] Specifically, the size of the metal plastic tile body 3 is determined, and then the controller is used to control the driving motor 128, so that the driving motor 128 drives the connecting column 126 to rotate, so that the connecting column 126 drives the gear 125 to rotate, so that the gear 125 drives the semi-toothed ring 122 to slide on the side wall of the slide rail 121, so that the semi-toothed ring 122 drives the first mounting plate 123 to move, so that the first mounting plate 123 drives the fixing assembly 14 to move to an appropriate position, and then the servo motor 11 is started, so that the servo motor 11 drives the bidirectional threaded rod 111 to rotate, so that the bidirectional threaded rod 111 drives the slider 112 to slide on the inner wall of the first through groove 101, so that the slider 112 drives the mounting seat 12 to move linearly, so that the mounting seat 12 drives the fixing assembly 14 to clamp the metal plastic tile body 3, thereby increasing the stability of the metal plastic tile body 3 during brazing, and using the arc-shaped mounting seat 12, so that the fixing assembly 14 is suitable for clamping the metal plastic tile body 3 with arc-shaped side walls or straight side walls, and has a wide range of uses.

[0044] The fixing assembly 14 includes a mounting block 140, and a card slot 141 is provided on both side walls of the mounting block 140. A first connecting seat 142 is provided on the upper end of each mounting block 140. A threaded column 143 is movably connected inside the first connecting seat 142. A first limiting plate 144 is fixedly connected to the side wall of the threaded column 143.

The first connecting seat 142 is fixedly connected to the side wall of the second connecting seat 146, and the side wall of the second connecting seat 146 away from the first connecting seat 142 is provided with two second mounting grooves 1461, the inner wall of the second mounting groove 1461 is fixedly connected to the second spring 147, one end of the second spring 147 is fixedly connected to the push block 148, the push block 148 is slidably connected to the inner wall of the second mounting groove 1461, and one end of the push block 148 away from the second spring 147 is fixedly connected to the rubber plate 149.

[0045] Specifically, the threaded column 143 is rotated and the threaded connection between the lower end side wall of the threaded column 143 and the mounting block 140 is coordinated to make the threaded column 143 move upward, and the first limiting plate 144 and the second limiting plate 145 are used to limit the first connecting seat 142 upward, so that the first connecting seat 142 drives the second connecting seat 146 to move upward, thereby adjusting the height of the rubber plate 149 to make it suitable for clamping the metal plastic tile body 3 of different thicknesses, and utilizing the elastic force of the second spring 147 and the elastic characteristics of the rubber plate 149 to ensure a sufficiently large release area when clamping the metal plastic tile body 3 with an arc-shaped side wall, thereby increasing the clamping stability.

[0046] The side wall of the connecting column 126 is fixedly connected with a rotating plate 127, and the side wall of the rotating plate 127 is evenly fixedly connected with four driving blocks 1271. The impact assembly 13 includes a mounting cylinder 131, and a sliding groove 132 is opened on the side wall of the mounting cylinder 131. Two limiting rings 133 are fixedly connected to the inner wall of the mounting cylinder 131, and the inner wall of the limiting ring 133 is movably connected with an impact column 134. The side wall of the impact column 134 is fixedly connected with a mounting ring 135, and the side wall of the impact column 134 is movably sleeved with a first spring 136.

[0047] Specifically, when the driving motor 128 drives the connecting column 126 to rotate, the connecting column 126 drives the rotating plate 127 to rotate, so that the rotating plate 127 drives the driving block 1271 to rotate, so that the driving block 1271 pushes the push plate 137 to slide on the inner wall of the slide groove 132, so that the push plate 137 squeezes or stretches the first spring 136 through the mounting ring 135. When the driving block 1271 releases the push plate 137, the elastic force of the first spring 136 is utilized to make the first spring 136 drive the impact column 134 to impact the inner wall of the mounting seat 12 through the mounting ring 135, and then the welding slag accumulated on the mounting seat 12 is discharged from the discharge trough 120 through the guide plate 129, and the linkage between the discharge of the welding slag and the position adjustment of the fixed component 14 is realized.

[0048] Furthermore, in order to enhance the stability of the device, Figure 5-Figure 9 As shown, the following preferred technical solutions are provided.

[0049] A first mounting groove 103 is provided at the upper end of the base 1, and a mounting column 15 is movably connected to the inner wall of the first mounting groove 103. A placement seat 16 is fixedly connected to the upper end of the mounting column 15, and the placement seat 16 is circular in shape and is used to place the metal plastic tile body 3 using the placement seat 16.

[0052] Two groups of second through grooves 102 are opened at the upper end of the base 1, and the second through grooves 102 are respectively located on both sides of the first through groove 101. The inner wall of the second through groove 102 is slidably connected to the limiting block 113, and the upper end of the limiting block 113 is fixedly connected to the mounting seat 12, which is used to limit the mounting seat 12 by using the limiting block 113 to increase the stability of the linear motion of the mounting seat 12.

[0053] The two side walls of the push plate 137 away from the mounting ring 135 are both provided with inclined surfaces, the two ends of the mounting cylinder 131 are arc-shaped, and the length of the impact column 134 is smaller than the length of the mounting cylinder 131, which is used to increase the smoothness of the driving block 1271 pushing the push plate 137 to slide on the inner wall of the slide groove 132, and to increase the fit between the two ends of the mounting cylinder 131 and the inner wall of the mounting seat 12, and to avoid the impact column 134 directly contacting the inner wall of the mounting seat 12, thereby causing the push plate 137 to directly jam the driving block 1271.

[0054] The servo motor 11 and the drive motor 128 are both electrically connected to an external controller, so as to control the opening and closing of the servo motor 11 and the drive motor 128 by the controller.

[0055] Beneficial effects: The metal plastic tile body 3 with arc-shaped or straight-line side walls can be clamped by the arc-shaped mounting seat 12 and the fixing assembly 14. There is no need to prepare specific fixing equipment for metal plastic tile bodies 3 of different shapes, which greatly improves the utilization rate and flexibility of the equipment, reduces production costs and inventory pressure, and directly rotates the threaded column 143 to adjust the height of the rubber plate 149, thereby achieving the clamping of metal plastic tile bodies 3 of different thicknesses without complicated adjustment steps or additional tools, thereby improving work efficiency and convenience of operation. Secondly, the driving motor 128 simultaneously drives the gear 125 and the rotating plate 127 to rotate, thereby realizing the linkage between the discharge of welding slag and the position adjustment of the two sets of fixing assemblies 14, simplifying the operation process, and improving the degree of automation in the welding process, reducing manual intervention, and further improving work efficiency.
