Description

Technical Field

[0001] This utility model relates to the field of spot welding machines, and more specifically, to an automatic spot welding machine. Background Technology

[0002] An automatic spot welding machine is a device used for automated welding. It primarily uses an electric current to generate heat in the workpiece, causing it to melt and bond in a localized area. It is widely used in metal processing, electronics, and automotive manufacturing. Automatic spot welding machines improve production efficiency, ensure welding quality, and reduce errors caused by manual operation.

[0003] Automatic spot welding machines are often equipped with movable welding heads and clamps. The clamps are used to fix the workpiece, and then the welding head contacts the workpiece to perform spot welding. For certain metal plate structures with many holes, irregular shapes, and large volumes, it is difficult to achieve stable clamping of the metal plate using existing clamps, such as clamps that use cylinders and chucks to hold the workpiece on both sides. This can lead to unstable clamping, weld point displacement, and consequently affect the welding pass rate. Utility Model Content

Detailed Implementation

[0025] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose.

[0026] like Figures 1-7 As shown, this utility model provides an automatic spot welding machine, including a main frame 1, an xy translation component 2 disposed within the main frame 1, a mounting base 3 disposed on the xy translation component 2, a fixing clamp 5 detachably disposed on the mounting base 3, and a welding head structure 4 disposed opposite to the fixing clamp 5. Irregularly edged metal plate-shaped weldments are fixed by the fixing clamp 5. The xy translation component 2 drives the mounting base 3 to move horizontally along the x and y directions, where x and y are two mutually perpendicular directions in the plane. This positions the weldment's welding point at the bottom of the welding head structure 4, which then descends to the welding point position for welding.

[0027] like Figure 3As shown, the fixing clamp 5 includes a first mounting base 6 and a second mounting base 7 arranged sequentially from top to bottom, and a fixing component for fixing the weldment on the first mounting base 6. The first mounting base 6 and the second mounting base 7 are detachably connected. The mounting base 3 is provided with two parallel limiting plates 21, and the second mounting base 7 is located between the two limiting plates 21. The mounting base 3 is also provided with a second limiting pin 22 passing through the second mounting base. The fixing clamp 5 can be detached from the mounting base 3 and is limited by the limiting plates 21 and the second limiting pin 22, simplifying the installation process and facilitating the disassembly of the fixing clamp 5. The first mounting base 6 and the second mounting base 7 are connected by four pins. The weldment is fixed on the first mounting base 6, and the fixing component on the first mounting base 6 is also adaptively adjusted according to the specific shape of the weldment. Therefore, the first mounting base 6 can be disassembled, and weldments of different shapes can be fixed by replacing the first mounting base 6.

[0028] like Figure 6 As shown, the fixing assembly includes spaced-apart limiting blocks 8 and a clamping member located inside the limiting blocks 8, the clamping member being pressed against the weldment. The mounting base 6 is provided with a limiting pin 19 passing through a hole in the weldment. When the weldment with the hole is placed, the limiting pin 19 passes through the hole, and simultaneously the edge of the weldment abuts against the limiting blocks 8, and then the clamping member presses the weldment firmly. The structure of the clamping member in this design can be used to fix weldments with similar structures.

[0029] Example 1

[0030] like Figures 5-7 As shown, the clamping component includes a rotating base 9 mounted on the mounting base 6, a pressure plate 10 mounted on the rotating base 9, and a locking block 11 located on one side of the pressure plate 10. The pressure plate 10 has a locking slot 12 corresponding to the locking block 11. The mounting base 6 has a locking block limiting groove 13, and a compression spring structure 14 connected to the locking block 11 is disposed within the locking block limiting groove 13. When the pressure plate 10 presses against the surface of the weldment, the locking block 11 is engaged in the locking slot 12.

[0031] In the above scheme, the limiting pin 19 passes through the hole on the weldment and is positioned on the side by the limiting block 8. Then, the pressure plate 10 is rotated to press against the surface of the weldment. Next, the locking block 11 is released, and the compression spring structure 14 on the back of the locking block 11 resets and pushes the locking block 11 to move within the locking block limiting groove 13 until it is locked in the locking slot 12, thus fixing the pressure plate 10. When it is necessary to remove the plate, the limiting of the pressure plate 10 by the locking block 11 can be released. Through the cooperation of the limiting block 8, the limiting pin 19, the pressure plate 10 and the locking block 11, the assembly and disassembly of the weldment can be quickly realized, while ensuring that the weldment is more firmly fixed and the fixed position is accurate, thereby ensuring the accuracy of the weldment and improving the welding qualification rate and welding efficiency.

[0032] Example 2

[0033] like Figure 4 As shown, in another embodiment of the clamping component of this solution, the clamping component includes a second pressure plate 16 and a pressing block 15 disposed within the second pressure plate 16. The second pressure plate 16 is provided with a limiting hole 17 for the first limiting pin 19 to pass through and a mounting groove for the mounting block 15. The pressing block 15 is movably disposed within the mounting groove, and the pressing block 15 is provided with a clearance hole corresponding to the limiting hole. A second compression spring structure 18 is provided within the mounting groove, which contacts the pressing block 15. The first limiting pin 19 is provided with an annular notch 20, and the edge of the clearance hole abuts against the annular notch 20.

[0034] In the above scheme, the limiting pin 19 passes through the hole in the weldment and is positioned laterally by the limiting block 8. Then, the pressure plate 16 is pressed onto the weldment, and the limiting pin 19 passes through the clearance hole on the pressure block 15 and the limiting hole 17 on the pressure plate 16. Because of the presence of the compression spring structure 18, when no external force is applied, the compression spring pushes the pressure block 15 to move, so that the edge of the clearance hole 17 abuts against the annular notch 20, thereby locking the pressure plate 16. When the welding is finished and the weldment is removed, the pressure plate is pushed so that the edge of the clearance hole 17 does not contact the annular notch 20, and the weldment can be removed.

[0035] The fixing fixture 5 of this solution is applicable to most plate-shaped weldments with holes that have similar structures. The positions of the limiting pin 19, the clamping part and the limiting block 8 can be adjusted according to the specific shape of the plate. The fixing fixture 5 of this solution can quickly realize the assembly and disassembly of the weldment, while ensuring that the position of the weldment after fixing is accurate. There is no situation where the welding point is offset due to inaccurate fixing position, thus ensuring the qualification rate of the welded products.

[0036] like Figure 1 As shown, to ensure safety, a safety light curtain 23 is installed on the main frame 1. The light curtain sensor sends a safety signal to the controller, which illuminates the green safety indicator light, turns off the red fault indicator light, and activates the relay, allowing the equipment to start. When there is an obstruction within the protection area of ​​the light curtain sensor, such as when personnel enter, the light is blocked. The light curtain sensor immediately sends an obstruction signal to the controller, which turns off the green safety indicator light, illuminates the red fault indicator light, and immediately releases the relay, stopping the equipment and preventing it from starting, thus ensuring personnel safety.
