[0032] In the description of this invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this invention.

[0033] Example

[0034] To address the limitations of existing technologies Figure 1 The sheet metal product processing shown has some shortcomings, please refer to... Figures 2-3As shown, this application discloses a fully automatic riveting and welding integrated machine, including a machine base 10, a first riveting mechanism 20, a second riveting mechanism 30 and a double-sided welding mechanism 40. The left and right sides of the machine base 10 are respectively provided with clamping mechanisms 50 for clamping the left and right parts of the product. Before riveting and welding, the operator splices sheet metal parts a and c together and places them on the machine base 10. Then, sheet metal parts b and d are placed on top of sheet metal parts a and c respectively. After that, the two clamping mechanisms 50 press down on sheet metal parts b and d respectively.

[0035] The first riveting mechanism 20 is located on the left side of the machine base 10 to rivet and fix the left side of the product, and the second riveting mechanism 30 is located on the right side of the machine base 10 to rivet and fix the right side of the product.

[0036] The double-sided welding mechanism 40 is located in the middle of the machine base 10 to weld the middle part of the product;

[0037] After sheet metal parts a and c are placed on the machine base 10, and sheet metal parts b and d are placed above sheet metal parts a and c respectively, and are pressed together by two pressing mechanisms 50, the first riveting mechanism 20 rivets sheet metal parts a and b together with several rivets, the second riveting mechanism 30 rivets sheet metal parts c and d together with several rivets, and the double-sided welding mechanism 40 welds and fixes the joint of sheet metal parts a and c on both sides.

[0038] Specifically, the clamping mechanism 50 of this application includes a mounting groove 51 opened on the rear side of the machine base 10, a cylinder 52 disposed in the mounting groove 51, and a pressure plate 53 connected to the piston rod of the cylinder 52. After sheet metal parts a and c are placed on the machine base 10 and sheet metal parts b and d are placed above sheet metal parts a and c respectively, the cylinders 52 included in the two clamping mechanisms 50 will drive the pressure plate 53 to descend, thereby pressing sheet metal part b onto sheet metal part a and pressing sheet metal part d onto sheet metal part c.

[0039] In order to achieve the clamping and positioning of the sheet metal products by the two clamping mechanisms 50 without affecting the clamping of each part, this application provides a U-shaped positioning frame 60 above the machine base 10. Two vertical slots 61 are opened on the rear side of the U-shaped positioning frame 60 for the avoidance of the pressure plate 53. In actual use, the operator needs to place sheet metal parts a and c inside the U-shaped positioning frame 60 and then place sheet metal parts b and d above sheet metal parts a and c respectively. When the cylinder 52 drives the pressure plate 53 to descend, the pressure plate 53 will pass through the vertical slots 61 and connect with sheet metal parts b and d.

[0040] Specifically, the first riveting mechanism 20 of this application includes a first XYZ axis moving platform 21 disposed on the left side of the machine base 10, a first pneumatic riveting machine 22 disposed on the first XYZ axis moving platform 21, and a first vision inspection camera 23 disposed on the pneumatic part of the first pneumatic riveting machine 22. When riveting and fixing sheet metal part b to sheet metal part a, the first XYZ axis moving platform 21 drives the first pneumatic riveting machine 22 and the first vision inspection camera 23 disposed on the pneumatic part of the first pneumatic riveting machine 22 to move along the X-axis, Y-axis and Z-axis. During this process, the first vision inspection camera 23 disposed on the pneumatic part of the first pneumatic riveting machine 22 will detect the rivet position. After that, the first pneumatic riveting machine 22 will screw several rivets between sheet metal part b and sheet metal part a.

[0041] Similarly, the second riveting mechanism 30 of this application includes a second XYZ axis moving platform 31 disposed on the left side of the machine base 10, a second pneumatic riveting machine 32 disposed on the second XYZ axis moving platform 31, and a second vision inspection camera 33 disposed on the pneumatic part of the second pneumatic riveting machine 32. When riveting and fixing sheet metal part d and sheet metal part c, the second XYZ axis moving platform 31 drives the second pneumatic riveting machine 32 and the second vision inspection camera 33 disposed on the pneumatic part of the second pneumatic riveting machine 32 to move along the X-axis, Y-axis and Z-axis. During this process, the second vision inspection camera 33 disposed on the pneumatic part of the second pneumatic riveting machine 32 will detect the rivet position. After that, the second pneumatic riveting machine 32 will screw several rivets between sheet metal part d and sheet metal part c.

[0042] In addition, in order to ensure that the rivets will not be riveted into the machine base 10, this application also provides a number of rivet clearance holes 14 on the left and right sides of the machine base 10 corresponding to the riveting positions. The rivets riveted by the first riveting mechanism 20 and the second riveting mechanism 30 during operation will be located in the rivet clearance holes 14.

[0043] Specifically, the double-sided welding mechanism 40 of this application includes a vertical beam 41 vertically arranged on the rear side of the machine base 10, a bidirectional drive module 42 vertically arranged on the front side of the vertical beam 41, two Y-axis drive modules 43 connected to the two drive units of the bidirectional drive module 42 on the upper and lower sides of the machine base 10 respectively, two X-axis drive modules 44 connected to the two Y-axis drive modules 43 respectively, and two laser welders 45 connected to the two X-axis drive modules 44 respectively. When welding sheet metal parts a and c, the bidirectional drive module 42 drives the two Y-axis drive modules 43 to move towards each other, so that the two laser welders 45 contact the seam of sheet metal parts a and c at the starting position. After that, when the two Y-axis drive modules 43 and the two X-axis drive modules 44 drive the two laser welders 45 to move along the X-axis and Y-axis respectively, the two laser welders 45 can simultaneously weld the seam on both sides of the sheet metal product.

[0044] Based on the above structure, this application also provides a through groove 11 in the middle area of ​​the machine base 10. In actual use, the laser welder 45 corresponding to the machine base 10 needs to pass through the through groove 11 to contact the splice seam of sheet metal parts a and c.

[0045] In a preferred embodiment, the present application also provides a cold air chamber 12 on the left side of the central region of the machine tool 10, and a plurality of exhaust oblique holes 13 communicating with the cold air chamber 12 are provided on the side wall of the through groove 11. After the two laser welders 45 weld the sheet metal parts a and c together, the cold air chamber 12 will spray cold air into the weld position through the exhaust oblique holes 13 and cool the area as a whole through heat conduction.

[0046] It should be noted that the cold air chamber 12 needs to be connected to an external refrigeration unit to provide it with cold air.

[0047] Since the all-in-one machine provided in this application involves riveting and welding, which has a high risk factor, this application provides a grating transmitter 70 and a grating receiver 80 on the left and right sides of the machine base 10, respectively. When the all-in-one machine is working, if the grating receiver 80 does not receive the light from the grating transmitter 70, the entire machine will stop immediately.
