When spot welding workpieces, it is necessary to ensure the uniformity of the workpiece welding points in order to ensure the firmness and aesthetics of the workpiece after spot welding. At present, when spot welding workpieces, workers generally hold a welding gun in one hand and a welding rod in the other hand to spot weld the workpiece. In this way, before spot welding, workers need to confirm the position to be spot welded before spot welding can be carried out. It takes a lot of time for workers to confirm the welding points, and the accuracy of the welding points cannot be guaranteed, which affects the quality of subsequent spot welding.

[0055] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0056] Example 1

[0057] A metal welding spot preset machine, such as Figures 1-6 As shown, it includes a welding point preset machine body 1, an embossing mechanism 3 and a marking mechanism 4. A metal weldment 2 is placed on the top of the welding point preset machine body 1. An embossing mechanism 3 is provided on the upper part of the welding point preset machine body 1. The embossing mechanism 3 is used to imprint the top of the metal weldment 2. A marking mechanism 4 is provided on the front lower side of the embossing mechanism 3. The marking mechanism 4 is used to mark the top of the metal weldment 2. The embossing mechanism 3 includes a connecting frame 31, a seal shell 32, a multi-stage cylinder 33, a rodless cylinder 34 and a printing wheel 35. The front side of the upper part of the welding point preset machine body 1 is fixed with a rodless cylinder 34 by bolts. The bottom of the slider of the rodless cylinder 34 is fixed with a multi-stage cylinder 33 by bolts. The bottom of the piston rod of the multi-stage cylinder 33 is connected to the connecting frame 31. The left and right sides of the bottom of the connecting frame 31 are fixed with seal shells 32. The two seal shells The printing wheel 35 is rotatably connected inside 32, and the printing wheel 35 is used to imprint the surface of the metal weldment 2. The marking mechanism 4 includes a guide rail 41, a moving block 42, an ink cartridge 43, a screw rod 44 and a first motor 45. The front lower side of the two seal shells 32 is fixed with a guide rail 41 by bolts, and the moving block 42 is slidably connected inside the guide rail 41. The ink cartridge 43 is fixed on the left side of the guide rail 41. The ink cartridge 43 is used to mark the top of the metal weldment 2. The right end of the ink line in the ink cartridge 43 is connected to the lower left side of the moving block 42. The guide rail 41 is rotatably connected to the screw rod 44, and the screw rod 44 is threadedly connected to the moving block 42. The right side of the guide rail 41 is fixed with a first motor 45 by bolts, and the output shaft of the first motor 45 is connected to the right side of the screw rod 44 through a coupling.

[0058] When in use, the two metal welds 2 to be marked are placed on the top of the welding point preset machine body 1, and then the rodless cylinder 34 is started. The rodless cylinder 34 drives the multi-stage cylinder 33 to move for two seconds through the slider and stops. Then the staff starts the multi-stage cylinder 33, and the piston rod of the multi-stage cylinder 33 extends to drive the connecting frame 31, the seal shell 32 and the printing wheel 35 to move downward. The seal shell 32 drives the guide slide 41, the moving block 42, the ink cartridge 43, the screw rod 44 and the first motor 45 to move downward. When the ink cartridge 43 moves downward to contact the metal weld 2, the first motor 45 is started, and the output shaft of the first motor 45 drives the screw rod 44 to rotate, and the screw rod 44 drives the moving block 42 to move to the right, so that the moving block 42 pulls out the ink line in the ink cartridge 43, so that the ink line leaves an ink mark on the surface of the metal weld 2. In this way, the surfaces of the two metal welds 2 can be marked, and at the same time, the printing wheel 35 moves downward to contact the surface of the steel plate. The wheel 35 can print numbers on the metal weldment 2. In this way, after the metal weldment 2 is removed, it is convenient for subsequent staff to use marks and ink to align the two metal weldments 2, thereby facilitating spot welding. There is no need to manually find a suitable spot welding position, saving working time. After marking one place, the output shaft of the first motor 45 is controlled to reverse and reset, driving the screw rod 44 to reverse and reset, and the screw rod 44 drives the moving block 42 to move to the left and reset, and the ink cartridge 43 is pulled to retract the ink line, and then the piston rod of the multi-stage cylinder 33 is controlled to retract and reset, driving the connecting frame 31, the seal shell 32 and the printing wheel 35 to move upward and reset, while driving the guide slide 41, the moving block 42, the ink cartridge 43, the screw rod 44 and the first motor 45 to move upward and reset, and then repeat the above operation to mark the remaining positions of the metal weldment 2. In this way, the marking can be made uniform. After marking is completed, the first motor 45, the rodless cylinder 34 and the multi-stage cylinder 33 are turned off.

[0059] Example 2

[0060] On the basis of Example 1, Figure 2 、 Figure 7 and Figure 8As shown, it also includes a pattern changing mechanism 5, which is used to automatically change the surface of the printing wheel 35. The pattern changing mechanism 5 includes a telescopic rod 51, a telescopic spring 52, a rack 53 and a one-way gear 54. The left rear side of the two seal shells 32 is fixedly connected to the telescopic rod 51, the bottom of the two telescopic rods 51 is fixedly connected to the rack 53, and the two telescopic rods 51 are each covered with a telescopic spring 52. The two ends of the telescopic spring 52 are respectively connected to the telescopic rod 51 and the top of the rack 53. The rear sides of the two printing wheels 35 are connected to the one-way gear 54 through a one-way clutch. When the stamp shell 32 moves downward, it drives the telescopic rod 51, telescopic spring 52, rack 53 and one-way gear 54 to move downward. When the rack 53 moves downward to contact the surface of the metal weldment 2, the rack 53 moves upward to drive the one-way gear 54 to rotate. The telescopic rod 51 and the telescopic spring 52 are both compressed. Under the action of the one-way clutch, the one-way gear 54 idles. When the stamp shell 32 moves upward, it drives the telescopic rod 51, telescopic spring 52, rack 53 and one-way gear 54 to move upward and reset. The telescopic spring 52 resets, driving the telescopic rod 51 to extend, thereby driving the rack 53 to move downward and reset. The rack 53 drives the one-way gear 54 to reverse, and the one-way gear 54 drives the printing wheel 35 to rotate and change the surface. In this way, when the next stamping is performed, the numbers stamped each time can be different, which makes it convenient for the staff to align the two metal weldments 2 with the help of the stamped numbers, which is convenient for subsequent spot welding operations.

[0061] like Figure 1 、 Figure 2 、 Figure 9 and Figure 10 As shown, it also includes a marking enhancement mechanism 6, which is used to enhance the ink mark. The marking enhancement mechanism 6 includes a moving rod 61, a support rod 62, a support block 63 and a top rod 64. The support block 63 is welded on the right front side of the guide rail 41, and the support rod 62 is welded on the top of the support block 63. The moving rod 61 is slidably connected inside the support rod 62. The rear side of the lower left part of the moving rod 61 is a V-shaped inclined surface, and the upper right part of the moving rod 61 is connected to a trapezoidal block. The front side of the moving block 42 is welded with a top rod 64, and the top rod 64 moves until it contacts the trapezoidal block on the right side of the moving rod 61. When the moving block 42 moves to the right, it drives the push rod 64 to move to the right. When the push rod 64 moves to the right and contacts the trapezoidal block on the moving rod 61, the push rod 64 drives the moving rod 61 to move upward, so that the moving rod 61 lifts the ink line of the ink cartridge 43. Since the rear side of the lower left part of the moving rod 61 is a V-shaped slope, the ink line of the ink cartridge 43 will be separated from the moving rod 61 after being lifted, so that the ink line of the ink cartridge 43 bounces to the surface of the metal weldment 2. In this way, the ink mark on the surface of the metal weldment 2 can be deepened, thereby preventing the ink mark from being too shallow, which causes the ink mark to be easily rubbed off.

[0062] like Figure 1 、 Figure 2 、 Figure 11 and Figure 12 As shown, it also includes a clamping mechanism 7, which is used to clamp and limit the metal weldment 2. The clamping mechanism 7 includes a limit frame 71, an electric slide rail 72 and a support plate 73. The support plate 73 is welded to the lower part of the welding point preset machine body 1, and the electric slide rail 72 is fixed to the top of the support plate 73 by bolts. Two limit frames 71 are slidably connected to the electric slide rail 72. The limit frames 71 are used to clamp and limit the metal weldment 2. The two limit frames 71 are both slidably connected to the welding point preset machine body 1. After placing the metal weldment 2 on the top of the welding point preset machine body 1, start the electric slide rail 72. The electric slide rail 72 controls the limit frame 71 to move toward each other, so that the limit frame 71 clamps the metal weldment 2 and positions the metal weldment 2 to prevent the position of the metal weldment 2 from shifting during marking, resulting in misalignment of the mark and affecting the subsequent welding effect. After marking is completed, the electric slide rail 72 controls the limit frame 71 to move outward to release the metal weldment 2, and then the electric slide rail 72 can be closed.

[0063] like Figure 1 、 Figure 2 and Figure 13 As shown, it also includes an advance wiping mechanism 8, which is used to wipe the surface of the metal weldment 2. The advance wiping mechanism 8 includes a fixed column 81, a brush rod 82 and a second motor 83. Two fixed columns 81 are welded to the front side of the top of the welding point preset machine body 1. The brush rod 82 is rotatably connected between the upper parts of the two fixed columns 81. The brush rod 82 is used to wipe the surface of the metal weldment 2. The right side of the fixed column 81 is fixedly connected to the second motor 83 by bolts. The output shaft of the second motor 83 is connected to the right side of the brush rod 82. When the metal weldment 2 is placed on the top of the welding point preset machine body 1, the second motor 83 is started. The output shaft of the second motor 83 drives the brush rod 82 to rotate. The metal weldment 2 contacts the brush rod 82, so that the brush rod 82 cleans the surface of the metal weldment 2 to prevent impurities and dust on the metal weldment 2 from affecting the clarity of the mark during subsequent marking. After wiping, the second motor 83 can be turned off.
