Mounting plate 103, with a hydraulic push rod 102 fixedly mounted on the top of mounting plate 103. The telescopic end of the hydraulic push rod 102 passes downward through mounting plate 103 and is fixedly connected to an upper mold 104 for riveting. A strip groove 105 is provided on the top rear side of the worktable 100. One end of an adjustable component is slidably connected to the inner cavity of the strip groove 105. A lower mold 108 corresponding to the upper mold 104 is provided at the end of the adjustable component located in the inner cavity of the strip groove 105. An adjusting component is provided at the bottom of the worktable 100 for adjusting the distance between the two sets of fixing plates 200 so as to clamp and fix metal plates of different widths.

[0030] The support includes a U-shaped plate 400 fixedly connected to the front end of each set of fixed plates 200. The surface of the workbench 100 and corresponding positions to the ends of each U-shaped plate 400 are provided with strip-shaped holes 106 for lateral sliding of the U-shaped plates 400. The ends of each U-shaped plate 400 extend upwards through the corresponding inner cavity of the strip-shaped hole 106. The front end of each U-shaped plate 400 extends downwards and has a circular groove 403 inside. A second spring 402 is provided inside the inner cavity of each circular groove 403. A disc 406 is provided on the top of each second spring 402. The surface of each disc 406 can slide up and down along the inner cavity of the corresponding circular groove 403. The top of each disc 406... The part is fixedly connected with abutment rods 407. The top of each set of abutment rods 407 passes through the corresponding side circular grooves 403 and abuts against the bottom surface of the metal plate under the push of the second spring 402. The end surface of the front side of the U-shaped plate 400 is provided with a limiting member for limiting the disc 406 to prevent the abutment rods 407 from sinking. The setting of the support member can effectively support the metal plate and prevent the plate from being suspended. It is especially suitable for larger plates and improves the riveting stability. At the same time, the U-shaped plate 400 can slide laterally along the strip hole 106 and can move together with the movement of the fixed plate 200, so that the support position can be adjusted for metal plates of different widths and the support flexibility can be enhanced.

[0031] The limiting component includes limiting holes 401 formed on the front end surface of the U-shaped plate 400 and arranged along its height. Each set of limiting holes 401 has a limiting bolt 404 inserted into its inner cavity. The ends of each set of limiting bolts 404 are fixedly connected to the surface of the corresponding side disc 406. The other end of each set of limiting bolts 404 is threadedly connected to a limiting nut 405. The end of the limiting nut 405 contacts the front surface of the U-shaped plate 400. By tightening the limiting nut 405, the limiting bolt 404 can be fixed in the limiting hole 401, thereby precisely controlling the height position of the abutment rod 407. The operation is simple and the adjustment is convenient. The height of the abutment rod 407 can be flexibly adjusted according to the metal plate of different thicknesses to ensure that the abutment rod 407 is in close contact with the bottom of the metal plate, providing stable support. At the same time, it prevents the abutment rod 407 from moving accidentally during the riveting process, further improving the reliability and practicality of the support component.

[0032] The clamping component includes a pressure plate 203 disposed within the cavity of the square groove 204. The front end of each pressure plate 203 is bent upwards, and several sets of guide rods 201 are fixedly connected to the top of each pressure plate 203. A first spring 202 is sleeved on the surface of the guide rods 201 located between the inner wall of one side of the square groove 204 and the pressure plate 203. Through the setting of the clamping component, the pressure plate 203 can directly apply pressure to the edge of the metal plate to achieve rapid clamping. At the same time, the cooperation between the guide rods 201 and the first spring 202 ensures that the pressure plate 203 remains stable during movement and avoids tilting. On the other hand, the elastic clamping force provided by the first spring 202 can adapt to metal plates of different thicknesses, ensuring the clamping effect while preventing damage to the plate due to excessive pressure.

[0033] The adjustable component includes a U-shaped frame 300 located on the rear side of the support frame 101. The upper end of the U-shaped frame 300 penetrates the surface of the support frame 101, and the lower end of the U-shaped frame 300 extends into the inner cavity of the strip groove 105. The lower mold 108 is fixedly installed on the lower end surface of the U-shaped frame 300. A hand-tightening bolt 301 is threadedly connected to the middle of the rear side of the U-shaped frame 300. The end thread of the hand-tightening bolt 301 penetrates the U-shaped frame 300 and is rotatably connected to the surface of the support frame 101. With the adjustable component, the U-shaped frame 300 slides in the strip groove 105, which can conveniently and quickly adjust the horizontal position of the upper mold 104 and the lower mold 108. This allows the upper mold 104 and the lower mold 108 to move flexibly according to different riveting parts of the metal sheet without disassembling and reinstalling the molds, greatly improving the efficiency of riveting work and enhancing the adaptability of the equipment to complex riveting tasks.

[0034] The adjusting component includes guide holes 107 located on the top of the workbench 100 and positioned opposite to each set of fixed plates 200. A double-acting lead screw 503 is rotatably connected to the bottom of the workbench 100. Bearing seats 506 are respectively fitted at both ends of the double-acting lead screw 503. The tops of the two sets of bearing seats 506 are respectively fixedly connected to the bottom of the workbench 100. Nut seats 504 are threaded to both ends of the double-acting lead screw 503. Connecting blocks 502 are respectively fixedly connected to the tops of the two sets of nut seats 504. The tops of the two sets of connecting blocks 502 pass through the guide holes 107. The guide hole 107 is fixedly connected to the bottom of the corresponding side fixing plate 200. One set of bidirectional lead screws 503 has a turntable 505 fixedly connected to its end, and the other set of bidirectional lead screws 503 has a fixing member for fixing the bidirectional lead screws 503. By adjusting the member, rotating the turntable 505 can drive the bidirectional lead screws 503 to rotate, so as to achieve precise adjustment of the distance between the two sets of fixing plates 200. It is not only easy to adjust, but also can quickly adapt to metal plates of different widths, improving the compatibility of the equipment with workpieces of different specifications.

[0035] The fixing component includes a fixing ring 500 rotatably sleeved on the end of another set of bidirectional lead screws 503. The top of the fixing ring 500 is fixedly connected to the bottom of the worktable 100, and the bottom of the fixing ring 500 is threaded with a fixing bolt 501. The end of the fixing bolt 501 passes through the fixing ring 500 upward and abuts against the end surface of the bidirectional lead screw 503. With the setting of the fixing component, after the position of the bidirectional lead screw 503 is adjusted, the fixing bolt 501 is tightened so that its end abuts against the surface of the bidirectional lead screw 503, thereby firmly fixing the bidirectional lead screw 503. This can effectively prevent the bidirectional lead screw 503 from rotating accidentally due to vibration and other factors during the riveting process, ensuring the stability of the spacing of the fixing plates 200, and thus ensuring the accuracy of the clamping position of the metal plate.

[0036] Working principle;

[0037] First, according to the width of the metal plate to be riveted, rotate the turntable 505 to drive the double-sided lead screw 503 to rotate, so that the nut seats 504 at both ends move on the double-sided lead screw 503, and then drive the fixing plate 200 to move through the connecting block 502 to adapt to metal plates of different widths. After adjustment, use the fixing parts to fix the double-sided lead screw 503. Tighten the fixing bolts 501 at the bottom of the fixing ring 500 so that its end abuts against the end surface of the double-sided lead screw 503 to prevent the double-sided lead screw 503 from rotating accidentally.

[0038] Subsequently, the two ends of the metal plate are inserted into the lower part of the corresponding side pressure plate 203, and the metal plate is pushed forward so that its riveting position is aligned with the upper mold 104. At the same time, the abutment rod 407 abuts against the bottom surface of the metal plate under the push of the second spring 402, and pushes the limiting screw upward so that the top of the abutment rod 407 is in complete contact with the bottom of the metal plate. Then, the limiting nut 405 on the surface of the limiting screw is tightened to fix the limiting screw and prevent the outer surface of the metal plate from being suspended during riveting.

[0039] At this point, the rivet is removed and placed at the desired riveting position, so that the end of the rivet is inserted into the inner cavity of the lower mold 108. Then, the hydraulic push rod 102 is activated, and the telescopic end of the hydraulic push rod 102 pushes the upper mold 104 downward to rivet the rivet.

[0040] When it is necessary to rivet the remaining positions in sequence, turn the hand-tightening bolt 301 to drive the U-shaped frame 300 to move along the strip groove 105, and then drive the upper mold 104 and the lower mold 108 to move to perform riveting operations at different positions.

[0041] Once the riveting is complete, the hydraulic push rod 102 retracts, simultaneously releasing the clamping parts and removing the riveted metal plate. If necessary, the spacing of the fixing plate 200 and the height of the support can be adjusted again for the next riveting operation.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
