Description

Technical Field

[0001] This utility model relates to the field of welding device technology, specifically to quick-change welding base plates. Background Technology

[0002] Currently, the welding of thin steel strips typically employs resistance welding with a welding machine. The positive and negative electrodes form a circuit. When current flows through the welding wheel and the negative electrode base plate, heat is generated at the interface, thus welding the two steel strips together. However, electrical discharge occurs during welding, producing weld slag at the copper base plate. Over time, this leaves a deep pit or burnt path on the copper base plate, gradually increasing the contact resistance and affecting the welding effect. In severe cases, this can lead to incomplete welds or even complete failure to weld. In such cases, the welding base plate needs to be replaced. Currently used welding base plates are large and heavy, making manual replacement cumbersome and time-consuming. Furthermore, the utilization rate of the welding base plate and the copper plate is extremely low. Utility Model Content

[0003] To address the shortcomings of existing technologies, the purpose of this invention is to provide a quick-change welding base plate to solve the problems mentioned in the background section. This invention features a novel structure that significantly reduces the weight of the copper plate requiring replacement, lowers the workload of operators, greatly reduces replacement time, saves downtime, and allows for rapid, one-button copper plate replacement. It also significantly improves the utilization rate of the copper busbars.

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] Please see Figures 1 to 4 This utility model provides a technical solution: a quick-change welding base plate, including a welding machine 1. The welding machine 1 has a welding platform 3 on its top. The welding platform 3 includes a pressure plate 31. The two ends of the pressure plate 31 are provided with limiting components 4. The limiting components 4 include mounting seats 43. The top of the mounting seat 43 is provided with a slot 46, and the two ends of the pressure plate 31 can slide into the slot 46. The upper end of the mounting seat 43 is provided with a pin hole 47. The surface of the mounting seat 43 is provided with two sets of insertion positions 45, and copper busbars 5 are inserted and installed inside the insertion positions 45. The top of the welding machine 1 is provided with a welding device 2. The bottom of the welding device 2 is provided with a welding wheel 21. When the device is in use, the pressure plate 31 is connected to the cylinder 33 through a connecting rod 32. When the welding wheel 21 is pressed down, it generates a welding current to achieve the welding purpose. During normal welding, the copper busbars 5 are installed on the welding platform 3. The mounting seat 43 is stuck in the sliding groove 42 and can move freely up and down. The pin 48 is not inserted. Upon insertion, the mounting base 43 will rest on the worktable. Two sets of pulleys 44 are installed on each of the two insertion points 45 of the mounting base 43. During normal welding, the pins 48 are not inserted into the pin holes 47. When the copper busbar 5 needs to be replaced, the cylinder 33 moves downward, causing the pressure plate 31 to move downward. After manually inserting the pins 48 into the pin holes 47, the cylinder 33 is triggered again, causing it to move upward, slowly lifting the pressure plate 31. At this time, because the pins 48 are inserted, the connection of the pressure plate 31... Shaft 34 lifts the mounting base 43 upwards. At this time, the copper plates on both sides are also lifted up by the force of pulley 44 and detached from the welding table. The copper plates are then supported by the pulleys 44 on both sides, allowing the operator to easily rotate the welding surface that needs to be replaced. After rotation, the cylinder 33 is pressed to trigger it, causing the cylinder 33 to move downwards, which in turn moves the pressure plate 31 downwards. At this time, the copper busbar 5 falls into its original welding position. The operator then pulls the pins 48 on both sides out of the pin holes 47, thus completing the rapid conversion of the copper busbar 5.

[0022] In this embodiment, the two ends of the pressure plate 31 are fixed with connecting shafts 34, and the connecting shafts 34 can be slidably inserted into the slot 46. The welding platform 3 also includes cylinders 33. The bottom of the welding machine 1 is fixed with two sets of cylinders 33, and the extended end of the cylinder 33 is fixed with a connecting rod 32. The connecting rod 32 is fixedly connected to the bottom sides of the pressure plate 31. The pressure plate 31 is connected to the cylinder 33 through the connecting rod 32, thereby driving the lifting and lowering movement of the pressure plate 31.

[0023] In this embodiment, the limiting component 4 also includes a vertical frame 41. The welding machine 1 is fixed on both sides of the mounting base 43 with the vertical frame 41, and a groove 42 is opened on the inner surface of the vertical frame 41. The mounting base 43 slides along the inside of the groove 42. The two sides of the insertion position 45 are rotatably mounted with pulleys 44, and the cylindrical end of the copper busbar 5 slides in contact with the pulley 44. A pin 48 is inserted into the pin hole 47. The pin 48 is pressed in contact with the top of the connecting shaft 34. The copper busbar 5 has a structure of a square rod in the middle and cylindrical ends. The two pulleys 44 and the insertion position 45 are used to limit the installation position of the copper busbar 5. The special structure of the copper busbar 5 with cylindrical ends can be easily inserted into the insertion position 45. The middle part is used for bearing. The connecting shaft 34 of the pressure plate 31 can be inserted into the slot 46. After being inserted by the pin 48, it drives the mounting base 43 to slide along the groove 42.

[0024] When using the device, the pressure plate 31 is connected to the cylinder 33 via the connecting rod 32. When the welding wheel 21 presses down, it generates welding current to achieve the welding purpose. During normal welding, the copper busbar 5 is installed on the welding platform 3. The mounting base 43 is locked in the slide groove 42 and can move freely up and down. When the pin 48 is not inserted, the mounting base 43 will fall on the platform. Each of the two insertion positions 45 of the mounting base 43 is equipped with two sets of pulleys 44. During normal welding, the pin 48 is not inserted into the pin hole 47. When it is necessary to replace the copper busbar 5, the cylinder 33 moves downward, driving the pressure plate 31 downward. The pins 48 on both sides are then manually inserted into the pin holes 47. When cylinder 33 is triggered again, it moves upward, causing pressure plate 31 to slowly lift. At this time, after pin 48 is inserted, the connecting shaft 34 of pressure plate 31 lifts mounting base 43 upward. The copper plates on both sides are also lifted up by the force of pulley 44, detaching from the welding table. The copper plates are then supported by pulleys 44 on both sides, allowing the operator to easily rotate the welding surface to be replaced. After rotation, cylinder 33 is triggered, causing it to move downward, causing pressure plate 31 to move downward. The copper busbar 5 then falls back into its original welding position. The operator then pulls pins 48 out of pin holes 47, completing the rapid conversion of copper busbar 5.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
