DETAILED DESCRIPTION

[0018] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0019] The embodiment of the present invention provides an electromagnetic pulse welding device, such as Figure 1-10As shown, the electromagnetic pulse welding device includes: a bottom box 1 and a mounting shell 2 fixed on the top thereof, wherein a processing box 3 is arranged inside the mounting shell 2; a welding table 4 arranged in the processing box 3, wherein an electromagnetic pulse coil 5 is arranged in the welding table 4, and the electromagnetic pulse coil 5 is arranged around the welding area; a sealing door assembled on the processing box 3 by hinges, wherein a visual observation window is arranged on the sealing door; an air guide mechanism, wherein the air guide mechanism is assembled on the processing box 3 for air guide and vacuuming; a limiting mechanism, wherein the limiting mechanism is arranged on the processing box 3 for limiting the position of the material plate to be welded; a cooling mechanism, wherein the cooling mechanism is arranged on the welding table 4 and the bottom box 1, and is used to cool the welding table 4.

[0020] In this embodiment, the plate to be welded is placed on the welding table 4 in the processing box 3, and the plate to be welded is limited by the limiting mechanism arranged on the processing box 3. Close the sealed door assembled on the processing box 3 by hinges, and use the gas guide mechanism assembled on the processing box 3 to conduct gas and vacuumize, so as to create a low-interference welding environment. Start up: An electromagnetic pulse generator should be arranged on the outer wall of the processing box 3, and the electromagnetic pulse coil 5 arranged around the welding area in the welding table 4 is energized to perform welding operation. After welding is completed, the welding table 4 is cooled by the cooling mechanism arranged on the welding table 4 and the bottom box 1; vacuuming by the gas guide mechanism effectively reduces the interference of the ambient gas on the welding process, solves the problem of easy oxidation of the workpiece surface when welding highly active metals (such as aluminum alloy plates), and improves the stability of the welding quality. The limiting mechanism can ensure the accurate position of the plate to be welded, which helps to improve the welding accuracy. The cooling mechanism cools down the welding table 4 in time, which is conducive to the continuous and stable operation of the equipment and prolongs the service life of the equipment; Compared with traditional electromagnetic pulse welding performed in a normal pressure environment, the device of the present invention greatly reduces the adverse effects of environmental factors on the welding process through vacuum operation, overcomes the problems of workpiece surface oxidation, pores and interface impurities that are difficult to avoid in traditional processes, thereby broadening the application scope of electromagnetic pulse welding, and is particularly suitable for high-activity metal welding scenarios with high requirements on welding quality.

[0021] In a further preferred embodiment of the present invention, the air guide mechanism includes: a first air guide pipe 6 fixedly connected to the processing box 3, the bottom end of the first air guide pipe 6 is connected to an air guide shell 7; a second air guide pipe 8 fixedly connected to the air guide shell 7, the second air guide pipe 8 is provided with a first solenoid valve 9; a first rotating rod 10 assembled on the air guide shell 7 through a sealed bearing, the first rotating rod 10 is fixed with a fan blade 11.

[0022] In this embodiment, when the processing box 3 needs to be evacuated by air conduction, the first solenoid valve 9 on the second air conduction pipe 8 is opened. The first rotating rod 10 is driven to rotate on the air conduction housing 7 through the sealed bearing, and the rotation of the first rotating rod 10 drives the fan blades 11 fixed thereon to rotate. The gas in the processing box 3 enters the air conduction housing 7 through the first air conduction pipe 6, and under the action of the fan blades 11, the gas is quickly drawn out and discharged through the second air conduction pipe 8, thereby realizing the air conduction vacuum operation in the processing box 3. The gas guide mechanism can efficiently evacuate the processing box 3 to create a low-interference welding environment. The first gas guide pipe 6 is fixedly connected to the processing box 3 to ensure the stability of the gas extraction path; the gas guide shell 7 plays a role in gas transition and convergence. The second gas guide pipe 8 and the first solenoid valve 9 are set to flexibly control the discharge of gas, which is convenient for adjusting the gas extraction process according to actual needs. The first rotating rod 10 and the fan blades 11 assembled by the sealed bearing provide powerful extraction power while ensuring the sealing of the gas guide shell 7 to prevent external gas from entering.

[0023] In a further preferred embodiment of the present invention, the limiting mechanism includes: a mounting rod 12 assembled on the processing box 3 through a sealed sliding sleeve, a mounting plate 13 being fixed at the bottom of the mounting rod 12; a threaded cylinder 20 assembled on the mounting plate 13 through a bearing; an adjustable threaded column 21 assembled in the threaded cylinder 20, a pressing plate 14 being fixed at the bottom end of the threaded column 21, for pressing the material plates to be welded; a first bidirectional screw 15 rotatably mounted on the processing box 3 through a sealed bearing, an assembly plate 16 being symmetrically threadedly sleeved on the first bidirectional screw 15, a slide rod 17 being slidably mounted on the assembly plate 16; a spring 18 sleeved on the slide rod 17; a limiting plate 19 fixed on the slide rod 17, for resisting the stacked material plates to be welded.

[0024] In this embodiment, the sheet to be welded is first placed on the welding table 4. The first bidirectional screw 15 is rotated. Since the symmetrical thread sleeve is provided with an assembly plate 16, the assembly plate 16 will move toward or in the opposite direction on the first bidirectional screw 15 during rotation. The movement of the assembly plate 16 drives the sliding rod 17 and the limit plate 19 fixed thereon to move, and the limit plate 19 presses against the sheet to be welded for preliminary positioning. Next, adjust the mounting rod 12 to move downward, and the pressing plate 14 descends and presses the sheet to be welded, further ensuring that the position of the sheet is fixed. The mounting rod 12 is assembled on the processing box 3 through a sealing sliding sleeve, which can ensure that the sealing of the processing box 3 is not affected when the position of the pressing plate 14 is adjusted; The limiting mechanism can accurately limit the plate to be welded. By adjusting the threaded column 21 and the threaded barrel 20, the degree of compression of the pressure plate 14 can be flexibly adjusted according to the actual situation such as the thickness of the plate to ensure that the plate is firmly fixed. The first bidirectional screw 15 drives the limiting plate 19 to move, which can adapt to the stacking of plates of different sizes and achieve rapid initial limiting. The spring 18 sleeved on the slide rod 17 can provide a certain buffer during the limiting process to avoid hard squeezing and damaging the plate. At the same time, the mounting rod 12 rotates and installs the first bidirectional screw 15 through a sealed sliding assembly and a sealed bearing, thereby maintaining a low-interference environment in the processing box 3, which is conducive to improving welding quality; Compared with the traditional limiting method, this limiting mechanism has more functions and strong adjustability. The traditional limiting method may only be able to achieve a single direction or simple limiting, and it is difficult to take into account the plates of different thicknesses and sizes. The limiting mechanism of the present invention can not only press the plate from above through the pressing plate 14, but also limit it from the side through the limiting plate 19, ensuring in multiple dimensions that the plate will not move during the welding process. Its adjustable structural design greatly improves the applicability to different types of plates, effectively improves the accuracy and stability of welding, and provides reliable limiting guarantees for high-quality electromagnetic pulse welding.

[0025] In a further preferred embodiment of the present invention, the cooling mechanism includes: a cavity 34 opened on the welding table 4, through which cooling liquid can flow; a box body 33 arranged in the bottom box 1, the box body 33 is divided into a left chamber and a right chamber, the left chamber is used to cool the returning coolant, and the left chamber is connected to the right chamber through an overflow pipe 47; a pump body 35 fixedly installed on the box body 33, the liquid inlet end of the pump body 35 is equipped with a liquid extraction pipe 36, and the liquid inlet end of the liquid extraction pipe 36 extends into the right chamber; a liquid supply pipe 37 installed on the liquid outlet end of the pump body 35, and the liquid outlet end of the liquid supply pipe 37 is connected to the cavity 34.

[0026] In this embodiment, the pump body 35 is turned on, and the pump body 35 extracts the coolant from the right chamber of the box body 33 through the liquid extraction pipe 36. The extracted coolant is pressurized by the pump body 35 and then transported to the cavity 34 on the welding table 4 through the liquid supply pipe 37. The coolant flows in the cavity 34 and absorbs the heat generated by the welding table 4 during the welding process. The coolant that has absorbed the heat flows back into the left chamber of the box body 33, and the left chamber cools down the reflux coolant. The cooled coolant flows into the right chamber through the overflow pipe 47, completing the circulation and cooling process of the coolant. The cooling mechanism can efficiently and continuously cool the welding table 4. The design of the cavity 34 on the welding table 4 increases the contact area between the coolant and the welding table 4, making the heat exchange more sufficient and the cooling effect significant. The left and right chambers separated in the box body 33 have clear division of labor. The left chamber focuses on cooling the reflux coolant, and the right chamber is responsible for providing coolant to the pump body 35, ensuring the circulation supply of the coolant. The pump body 35 provides power to ensure that the coolant can continue to flow in the system and maintain a stable cooling capacity. This cyclic cooling method can ensure that the welding table 4 maintains a suitable temperature during a long welding process, extend the service life of the equipment, and at the same time help to improve the welding quality and avoid welding defects caused by excessive temperature. Compared with traditional cooling methods, such as natural cooling or simple air cooling, the cooling mechanism adopts the method of coolant circulation, which has higher cooling efficiency. Natural cooling is slow and it is difficult to meet the demand for rapid cooling of equipment for continuous welding; air cooling is greatly affected by environmental factors and the cooling effect is unstable. The cooling mechanism of the present invention can accurately control the temperature of the welding table 4 without being disturbed by the external environment by circulating the coolant in a closed system. In addition, it has a compact structure and occupies little space. It can be installed in the bottom box 1 without affecting the layout of the overall equipment, providing a strong temperature guarantee for the efficient operation of the electromagnetic pulse welding device and improving the overall performance and reliability of the equipment.

[0027] In a further preferred embodiment of the present invention, a mesh plate 65 and a coil 48 for connecting to a cold air supply device are provided in the left chamber, a drain pipe 49 for draining liquid during liquid replacement is provided below the box body 33, a connecting pipe for connecting the left chamber with the right chamber is fixed on the drain pipe 49, and a valve is provided on the corresponding connecting pipe.

[0028] In this embodiment, during the cooling process of the reflux coolant in the left chamber, the cold air supply device is turned on, and the cold air enters the left chamber through the coil 48. The coil 48 evenly distributes the cold air and accelerates the cooling of the coolant. When the liquid needs to be replaced, the valve of the connecting pipe on the drain pipe 49 is opened, and the coolant in the left and right chambers is discharged through the drain pipe 49. The mesh plate 65 can filter the impurities in the coolant to prevent the impurities from accumulating in the left chamber and affecting the cooling effect, and at the same time, it can also prevent the impurities from clogging the pipe when draining; The connection between the coil 48 and the cold air supply device greatly improves the cooling efficiency of the left chamber for the coolant, which can quickly cool the coolant and ensure that the cooling mechanism can continue to work efficiently. The setting of the mesh plate 65 helps to maintain the cleanliness of the coolant in the left chamber, improve the stability and reliability of the cooling system, and reduce failures caused by impurities. The design of the drain pipe 49 and the connecting pipe and valve facilitates the replacement of the coolant, ensures that the coolant can be updated in time when the performance of the coolant decreases, maintains the optimal working state of the cooling mechanism, thereby ensuring the stable cooling of the welding table 4 and improving the overall operating stability of the welding equipment.

[0029] In a further preferred embodiment of the present invention, an adaptive adjustment mechanism for adjusting the threaded column 21 is provided on the processing box 3, and the adaptive adjustment mechanism includes: a first tooth plate 22 assembled on the processing box 3 through a sealed sliding sleeve, and a ball block 23 that can be lifted up by the material plate is fixed at the bottom of the first tooth plate 22; a rotating shaft 24 assembled on the processing box 3 through a sealed bearing, and a first gear 26 meshing with the first tooth plate 22 is fixed on the rotating shaft 24; and first bevel teeth 25 respectively fixed on the rotating shaft 24 and the threaded barrel 20 and meshing with each other.

[0030] In this embodiment, the sheet to be welded is placed on the welding table 4, and the sheet will lift up the ball block 23. The ball block 23 is connected to the first tooth plate 22, and the lifted ball block 23 drives the first tooth plate 22 to move upward. The first tooth plate 22 moves on the processing box 3 through the sealing sleeve to ensure the sealing of the processing box 3. When the first tooth plate 22 moves upward, the first gear 26 meshed with it begins to rotate. The first gear 26 is fixed on the rotating shaft 24, thereby driving the rotating shaft 24 to rotate. The first bevel gear 25 fixed on the rotating shaft 24 also rotates accordingly. Since the first bevel gear 25 is meshed with another first bevel gear 25 fixed on the threaded barrel 20, the threaded barrel 20 is driven to rotate. When the threaded barrel 20 rotates, the internal adjustable threaded column 21 will rotate downward, realizing the adaptive adjustment of the height of the pressure plate 14 to meet the welding requirements of sheets of different thicknesses. The adaptive adjustment mechanism can automatically adjust the height of the pressing plate 14 according to the thickness of the material plate to be welded, which greatly improves the convenience and efficiency of the welding operation. The setting of the ball block 23 makes the contact between the material plate and the first tooth plate 22 more sensitive, and can accurately sense the change in the thickness of the material plate. Through the transmission of a series of gears and bevel gears, the automatic conversion from the change in the height of the material plate to the adjustment of the threaded column 21 is realized, without the need for frequent manual adjustment, reducing the complexity of manual operation and the probability of error. At the same time, the use of sealed sleeves and sealed bearings maintains a low-interference environment in the processing box 3, ensures that the welding quality is not affected, and helps to improve the stability of the welding process and the consistency of product quality.

[0031] In a further preferred embodiment of the present invention, a fluid infusion port is provided at the top of the left chamber, a detachable cover is provided in the fluid infusion port, a pull ring is fixed at the top of the cover, and an exhaust hole is provided on the cover.

[0032] In this embodiment, when the coolant in the left chamber needs to be replenished, the operator pulls up the detachable cover fixed on the liquid replenishment port through the pull ring. The pull ring facilitates the operator to apply force so that the cover can be easily removed from the liquid replenishment port; then, the coolant is injected into the left chamber through the liquid replenishment port, and after the liquid replenishment operation is completed, the cover is reinstalled back to the liquid replenishment port.

[0033] In a further preferred embodiment of the present invention, a partition plate 55 for separating a detection space is fixed in the mounting shell 2, and a detection mechanism is arranged in the partition plate 55 for detecting the material plate after electromagnetic pulse welding.

[0034] In this embodiment, the detection mechanism and the partition plate 55 provide a dedicated space and equipment for the detection of the welded sheet material, which can timely conduct random inspections and evaluations of the welding quality, help to quickly discover welding defects during the production process, avoid unqualified products from entering the subsequent process, and improve the overall quality of the product.

[0035] In a further preferred embodiment of the present invention, a reflux pipe 38 communicating with the cavity 34 is disposed on the welding platform 4 , and a liquid outlet end of the reflux pipe 38 is communicated with a pressurizing shell 39 .

[0036] In this embodiment, during the operation of the cooling mechanism, the coolant flowing out of the cavity 34 on the welding table 4 is collected through the return pipe 38 connected to the cavity 34. The coolant flows to its outlet through the return pipe 38 and enters the supercharging shell 39. In the supercharging shell 39, the coolant is pressurized to meet the requirements of the subsequent cycle cooling for the coolant pressure, and then enters the box 33 and other subsequent links to continue to participate in the circulation.

[0037] In a further preferred embodiment of the present invention, support columns are symmetrically fixed to the bottom of the bottom box 1, foot pads are fixed to the bottom ends of the support columns, and inspection panels are assembled on the bottom box 1 and the mounting shell 2 by screws.

[0038] In this embodiment, when installing the electromagnetic pulse welding device, the support columns symmetrically fixed at the bottom of the bottom box 1 prop up the device, and the foot pads at the bottom of the support columns are in contact with the placement surface. When it is necessary to inspect the components inside the bottom box 1 or the installation shell 2, the screws fixing the inspection plate can be unscrewed with a screwdriver to remove the inspection plate, which is convenient for operators to enter the interior to inspect, repair and maintain the equipment. After the operation is completed, the inspection plate is put back in place and then fixed with screws.

[0039] In order to further improve the use effect of the device, in addition to the above scheme, this scheme also has the following embodiments: In another embodiment of the present invention, a transmission mechanism is provided in the bottom box 1 and the mounting shell 2, which is used to drive the first bidirectional screw 15 and the first rotating rod 10 to rotate and regulate the lifting and lowering of the mounting rod 12, and the transmission mechanism includes: a motor 50 and a speed regulator 51 fixed in the bottom box 1, and the input shaft of the speed regulator 51 is fixedly connected to the output shaft of the speed regulator 51 through a coupling; a bearing frame is assembled with a transmission rod 52 in the bottom box 1, and one end of the transmission rod 52 is fixedly connected to the output shaft of the speed regulator 51 through a coupling; second bevel teeth 53 are respectively fixed on the transmission rod 52 and the first rotating rod 10 and mesh with each other; and a bearing frame is assembled with a bearing seat. A first one-way screw 27 in the mounting shell 2, the first one-way screw 27 is threadedly assembled with a first set plate 28, a connecting plate 29 is fixed on the first set plate 28, and the bottom of the connecting plate 29 is connected to the mounting rod 12 by welding; a first guide rod 30 fixed in the mounting shell 2, the first guide rod 30 passes through the first set plate 28; third bevel teeth 54 are respectively fixed to the transmission rod 52 and the first one-way screw 27 and meshed with each other; a second tooth plate 31 fixed on the mounting plate 13; a second gear 32 fixed on the first bidirectional screw 15, the second gear 32 meshes with the second tooth plate 31.

[0040] In this embodiment, the motor 50 in the bottom box 1 is started, and the operation of the motor 50 drives the input shaft of the speed regulator 51 to rotate. After the speed regulator 51 adjusts the speed, the power is transmitted to the transmission rod 52 through the coupling. One end of the transmission rod 52 is connected to the output shaft of the speed regulator 51. When rotating, the second bevel gear 53 fixed thereon is driven to rotate. The second bevel gear 53 is meshed with the second bevel gear 53 fixed on the first rotating rod 10, thereby driving the first rotating rod 10 to rotate, and realizing the power supply to the fan blades 11 in the air guide mechanism. At the same time, the third bevel gear 54 on the transmission rod 52 rotates, meshes with the third bevel gear 54 fixed on the first one-way screw 27, and drives the first one-way screw 27 to rotate. The first one-way screw 27 is threadedly assembled with a first set plate 28. When the first set plate 28 is rotated, it moves along the axial direction of the first one-way screw 27. The first set plate 28 drives the connecting plate 29 fixed thereon to move. The connecting plate 29 is welded to the mounting rod 12, thereby realizing the lifting and lowering of the mounting rod 12, and the height of the pressing plate 14 can be adjusted. In addition, the second gear 32 on the first bidirectional screw 15 is meshed with the second toothed plate 31 fixed on the mounting plate 13. When the mounting rod 12 is lifted and lowered to drive the mounting plate 13 to move, the second toothed plate 31 moves accordingly, driving the second gear 32 to rotate, thereby rotating the first bidirectional screw 15 and adjusting the position of the limit plate 19. The setting of the transmission mechanism realizes the centralized power drive of multiple key components. The cooperation between the motor 50 and the speed regulator 51 can flexibly adjust the rotation speed according to the actual welding requirements. Through a series of transmissions, the power is efficiently transmitted to the first rotating rod 10, the first unidirectional screw 27 and the first bidirectional screw 15, so that the air guide mechanism, the limit mechanism and the pressure plate adjustment mechanism work together. This automated adjustment reduces manual operation, improves the accuracy and efficiency of adjustment, ensures that the parameters of each component can be quickly and accurately adjusted to the optimal state during the welding process, and improves the welding quality and production efficiency. At the same time, the linkage adjustment between the components helps to optimize the entire welding process and enhance the stability and reliability of the equipment. Compared with devices without transmission mechanisms, the present invention has significant advantages. Traditional devices may require manual operation to adjust each component separately, which is cumbersome and prone to inconsistent adjustments, resulting in unstable welding quality. The transmission mechanism realizes automation and centralized control, greatly simplifies the operation process, and reduces the influence of human factors.

[0041] In another embodiment of the present invention, the boost shell 39 and the left chamber are provided with a reflux stirring mechanism, and the reflux stirring mechanism includes: a stirring rod 45 assembled in the left chamber through a sealed bearing; a guide shell 40 assembled at the bottom of the boost shell 39 through a connecting pipe, a second solenoid valve 41 is provided on the connecting pipe, and the guide shell 40 is connected with the left chamber through a second liquid outlet pipe 44; a second rotating rod 42 assembled in the guide shell 40 through a sealed bearing, and an impeller 43 is fixed on the second rotating rod 42; a third gear 46 respectively fixed on the second rotating rod 42 and the stirring rod 45 and meshing with each other.

[0042] In this embodiment, after the coolant enters the supercharging shell 39 through the return pipe 38 and is pressurized, the second solenoid valve 41 on the connecting pipe is opened. The pressurized coolant flows into the guide shell 40 from the bottom of the supercharging shell 39 through the connecting pipe. In the guide shell 40, the coolant impacts the impeller 43 fixed on the second rotating rod 42, driving the second rotating rod 42 to rotate in the guide shell 40 through the sealed bearing. When the second rotating rod 42 rotates, the third gear 46 fixed thereon rotates accordingly. Since the third gear 46 is meshed with the third gear 46 fixed on the stirring rod 45, the stirring rod 45 is driven to rotate in the left chamber. The coolant flows from the guide shell 40 through the second liquid outlet pipe 44 into the left chamber. Under the stirring action of the stirring rod 45, it is fully mixed with the original coolant in the left chamber, and the heat dissipation and cooling process of the coolant is accelerated at the same time. The reflux stirring mechanism effectively improves the heat dissipation and mixing effect of the coolant during the reflux process. The impeller 43 rotates under the impact of the coolant, cleverly converting the kinetic energy of the coolant into rotational power, driving the stirring rod 45 to work, without the need for an additional power source, which is energy-saving and environmentally friendly. The stirring rod 45 stirs the coolant in the left chamber, which can quickly and evenly mix the high-temperature coolant that has just flowed back with the coolant that has been cooled in the left chamber, accelerate heat exchange, and improve overall heat dissipation efficiency. This stirring action also helps prevent the performance changes of the coolant due to local temperature differences, maintains the stability of the coolant, and ensures the continuous and efficient operation of the cooling mechanism, thereby improving the cooling effect of the welding table 4, which is beneficial to improving the welding quality.

[0043] In another embodiment of the present invention, the detection mechanism includes: a second bidirectional screw 56 assembled on the partition plate 55 through a bearing, a second set of plates 57 are symmetrically assembled on the second bidirectional screw 56, and a tension sensor 58 is assembled between the two second sets of plates 57; an insert 59 assembled on the second set of plates 57; a fourth bevel tooth 64 fixed on the second bidirectional screw 56 and the unidirectional screw 27 respectively and meshing with each other; an electric telescopic rod 62 fixed in the partition plate 55, and a placement plate 63 is provided on the output rod of the electric telescopic rod 62 for placing the sample material plate to be tested after welding; a display 61 arranged on the mounting shell 2 and compatible with the tension sensor 58; a second guide rod 60 fixed in the partition plate 55, and the second guide rod 60 passes through the second set of plates 57.

[0044] In this embodiment, the sample plate to be tested after welding is placed on the placement plate 63 on the output rod of the electric telescopic rod 62 in the partition plate 55; the electric telescopic rod 62 is started to push the placement plate 63 and the plate to a suitable testing position. The one-way screw 27 is rotated, and the fourth bevel gear 64 fixed on the one-way screw 27 rotates accordingly. Since the fourth bevel gear 64 is meshed with the fourth bevel gear 64 fixed on the second bidirectional screw 56, the second bidirectional screw 56 is driven to rotate. When the second bidirectional screw 56 rotates, the second set of plates 57 symmetrically mounted thereon will move in the opposite direction or in the opposite direction, and the second set of plates 57 moves smoothly under the guidance of the second guide rod 60. When the second set of plates 57 moves, the plug 59 mounted thereon is inserted into the wave gap of the plate after welding, and the tension sensor 58 mounted between the two second sets of plates 57 begins to detect the tension on the plug 59. The detection data is transmitted to the display 61 on the mounting shell 2 that is compatible with the tension sensor 58 for display in real time, and the operator can evaluate the welding quality according to the data of the display 61; The detection mechanism can accurately detect the quality indicators such as the welding strength of the plate after welding. The insert 59 cooperates with the wave gap of the plate after welding, and combined with the tension sensor 58, it can effectively measure the tensile strength of the weld, and provide quantitative data for evaluating the welding quality. The design of the second bidirectional screw 56 and the second set of plates 57 can flexibly adjust the position of the insert 59 to adapt to the detection of plates of different sizes and welding shapes. The electric telescopic rod 62 facilitates the rapid and accurate delivery of the material to be tested to the detection position, improves the detection efficiency, and the second guide rod 60 ensures that the second set of plates 57 moves smoothly to ensure the accuracy of the detection data. The display 61 displays the detection data in real time, which is convenient for the operator to intuitively understand the welding quality, helps to find welding defects in time, and provides a basis for improving the welding process.
