Description

Technical Field

[0001] The invention relates to the technical field of a traffic sign bracket welding device, and more specifically to a traffic sign bracket welding device. Background Art

[0002] Traffic sign brackets are structural components used to fix and support traffic signs. These brackets ensure that traffic signs are firmly installed in locations such as roads, streets or parking lots so that drivers and pedestrians can clearly see the instructions. Traffic sign brackets are usually made of metal to ensure sufficient strength and durability, and traffic sign brackets often require welding devices during use to ensure the stability of the connecting plates of each bracket.

[0003] When the existing traffic sign bracket welding device is used, the bracket connecting plate is fixed on the workbench, and the welding material is transported from the storage box to the feed pipe through the air pressure drive in the feed assembly, and the feed pipe transports it to the front end of the welding cylinder. At this time, the positioning mechanism in the welding cylinder is aligned with the predetermined welding point on the connecting plate, and then the welding program is started to make the electrode in the welding cylinder start to generate an arc or capacitor discharge, forming a high-temperature molten welding material (welding wire) and a metal sheet contact surface. As the arc or capacitor discharge continues, the welding material is melted and pressed into the metal sheet to form a strong metallurgical bond, thereby completing the welding, and then the position of the welding cylinder is adjusted by the mutual cooperation of the electric push rod and the electric slide rod, so as to weld the remaining positions of the bracket connecting plate.

[0004] In actual use of the prior art, the high temperature generated during the welding process between the welding tube and the welding material will cause local thermal expansion of the bracket connecting plate, resulting in deformation, warping, etc. of the connecting plate, thereby affecting the welding accuracy and the assembly quality of the components. Therefore, in order to solve the above technical problems, it is necessary to provide a traffic sign bracket welding device. Summary of the invention

[0005] The object of the present invention is to provide a traffic sign bracket welding device to solve the above-mentioned problem.

[0006] In order to achieve the above purpose, the technical solution provided by an embodiment of the present invention is as follows:

[0007] A traffic sign bracket welding device comprises a workbench, a hollow adsorption ring and a detection member, wherein a connecting frame is arranged on the upper surface of the workbench, an electric slide rod is arranged between the connecting frames, a moving block is arranged on the outer surface of the electric slide rod, an electric push rod is fixedly connected to the side of the moving block, an output shaft end of the electric push rod is fixedly connected to the connecting block, and a welding cylinder is fixedly connected to the bottom of the connecting block; the hollow adsorption ring is arranged on the outer surface of the welding cylinder, an adsorption member is fixedly connected to the inner cavity of the hollow adsorption ring, and the adsorption member comprises a negative pressure fan fixedly mounted on the upper surface of a short plate, a connecting pipe is arranged on the outer surface of the negative pressure fan, a plurality of adsorption tubes are distributed in an array inside the hollow adsorption ring, the adsorption tube and the connecting pipe are fixedly connected, and a cooler is arranged on the outer surface of the connecting pipe, so that the negative pressure fan generates and controls the required air pressure, and the pressure is transmitted to the adsorption tube through the connecting pipe to form an adsorption force, thereby stably fixing the workpiece to be welded and ensuring the accuracy during welding. The cooler can cool the gas transmitted by the connecting pipe to reduce the adverse effect of the heat generated during welding on the system;

[0008] The outer surface of the welding tube is provided with a fixing piece, and the fixing piece includes a short plate fixedly installed on the outer surface of the welding tube, and a plurality of fixing tubes are fixedly connected to the bottom of the short plate, and a telescopic rod is provided in the inner cavity of the fixing tube, and the output shaft end of the telescopic rod is fixedly connected to a fixing plate, and the fixing piece can be supported by the fixing plate, and the telescopic rod is telescoped in the fixing tube, and the fixing plate at the output shaft end contacts the bracket connecting plate to provide downward pressure, help stabilize the bracket connecting plate, reduce warping or deformation caused by thermal stress during welding, ensure the stability of the bracket connecting plate during welding and reduce thermal deformation;

[0009] The detection component is arranged in the inner cavity of the hollow adsorption ring, and the inner cavity of the hollow adsorption ring is provided with two detection cylinders, and the inner cavities of the detection cylinders are fixedly connected with electromagnetic plates, and the inner cavity of the detection cylinder is provided with a detection pen, and a strip hole is opened at the lower end of the detection pen, and a matching strip flexible membrane is arranged in the strip hole, and a hard arc plate is arranged on the detection pen, and the strip flexible membrane and the hard arc plate form a circular ring, and the detection pen and the strip flexible membrane constitute a hollow cylinder structure, and the inner cavity of the hollow adsorption ring and the hollow cylinder structure is filled with cooling oil, and a circulation pipe is arranged on the outer surface of the cooling oil, and a cold exchanger is arranged on the outer surface of the circulation pipe, and a sensor is arranged at the end of the detection pen away from the cooling oil, and a fixed pipe is arranged between the inner cavity of the detection pen and the hollow adsorption ring, and the cooling oil is used to absorb the heat generated during welding and reduce the temperature of the welding area by heat conduction.

[0010] As a further improvement of the present invention, the outer surface of the telescopic rod is sleeved with a spring, one end of the spring is connected to the inner cavity of the fixed cylinder, and the other end is connected to the fixed plate. The spring can reduce the vibration during welding, especially the impact force generated at the moment of welding. The spring can absorb this part of the energy, prevent hard contact between the fixed plate and the bracket connecting plate, avoid damaging the bracket connecting plate or affecting the welding quality.

[0011] As a further improvement of the present invention, a placement groove is opened on the outer surface of the workbench, and a feeding piece is arranged on the outer surface of the workbench. By placing the bracket connecting plate into the placement groove, the position of the bracket connecting plate during the welding process can be ensured to be accurate and without deviation. The feeding piece is used to feed the bolts to be welded into the welding cylinder, thereby improving the degree of automation of the welding process, reducing manual intervention, and improving production efficiency.

[0012] As a further improvement of the present invention, a plurality of threaded rods are provided on the upper surface of the workbench, and the outer surfaces of the threaded rods are threadedly connected to the long plates, and the outer surfaces of the long plates are fixedly connected to the pressure plates, and the upper surface of the workbench is fixedly connected to the sliding rods, and the outer surfaces of the sliding rods are slidably connected to the inside of the long plates, and the other ends of the threaded rods are fixedly connected to the rotating handles to adapt to bracket connecting plates of different thicknesses and sizes. The position of the connecting plates is adjusted by rotating the threaded rods, and then the pressure of the pressure plates on the bracket connecting plates is adjusted to ensure its stability during the welding process, and to apply uniform pressure to the bracket connecting plates during the welding process to prevent warping or deformation caused by welding thermal stress, while ensuring that the position of the bracket connecting plates remains unchanged during the welding process, thereby increasing the flexibility and adaptability of the welding tooling, and being suitable for a variety of bracket connecting plates and welding scenarios.

[0013] As a further improvement of the present invention, a magnet block is fixedly connected to the outer surface of the detection pen, and the electromagnetic plate and the magnet block are magnetically connected. During the welding process, the electromagnetic force of the magnet block is used to fix the bolt by the detection pen, thereby ensuring the stable position of the bolt during the welding process and preventing displacement caused by external interference or vibration during the welding process, thereby improving the welding accuracy and quality.

[0014] As a further improvement of the present invention, two movable holes are opened inside the welding cylinder, and the detection pen is slidably connected to the inner wall of the movable hole, allowing the detection pen to slide therein, ensuring that the detection pen can accurately contact the material being welded, thereby improving the automation level and efficiency of the welding process.

[0015] As a further improvement of the present invention, the inner cavity of the detection cylinder is provided with a slide rail, and the interior of the slide rail is slidably connected with a slider, and the slider is fixedly connected to the detection pen. The slide rail and the slider ensure that the detection pen can move smoothly along a predetermined trajectory. The strip flexible membrane and the hard arc plate enable the hard arc plate to increase the weight of the detection pen when the detection pen contacts the welding area, so that the strip flexible membrane contacts the welding area, ensuring that the cooling oil can evenly cover the welding area and achieve an efficient cooling effect.

[0016] Compared with the prior art, the advantages of the present invention are:

[0017] This solution can compress the bracket connecting plate through the mutual cooperation of the threaded rod, the connecting plate, the sliding rod and the pressure plate, to ensure that the bracket connecting plate will not be displaced or warped due to the welding thermal stress during welding, to ensure the stability of the welding process, and to transport the welding material into the welding cylinder through the feeding piece, and to adjust the position of the welding cylinder through the electric sliding rod and the electric push rod so that its front end is accurately aligned with the welding point.

[0018] When the welding tube is started for welding, the spring and the telescopic rod can ensure that the fixed plate is in close contact with the welding area, and exert downward pressure on the bracket connecting plate. At the same time, the negative pressure fan forms a negative pressure environment through the connecting tube and the adsorption tube, so that the negative pressure is given to the bracket connecting plate through the adsorption tube, so that it generates an upward adsorption force, which is balanced with the downward pressure exerted by the fixed plate, further stabilizing the bracket connecting plate to prevent it from warping or deformation during the welding process. The two forces work together to effectively control the thermal deformation during the welding process, ensure the stability of the welding point and the welding quality. At the same time, the cooler on the surface of the connecting tube converts the negative pressure gas circulating in the adsorption tube into cold air to cool the cooling oil, ensuring that the cooling oil maintains a low temperature during the circulation process, improving the cooling efficiency and reducing the thermal deformation during the welding process.

[0019] By starting the electromagnetic plate to generate negative magnetic force, the negative magnetic force repels the magnet block in the detection pen, prompting the detection pen to move outward along the slide rail through the slider until the detection pen contacts the bolt, thereby achieving precise positioning and fixation of the welding material and ensuring its stability during the welding process. During welding, the detection pen and the internal sensor monitor the welding status in real time to ensure the accuracy of the welding parameters and avoid the occurrence of leaking welds. At the same time, the rigid arc plate increases the weight of the detection pen to move it downward, prompting the strip flexible membrane under the detection pen to contact the welding area, so that the cooling oil in the inner cavity of the detection pen can instantly cool the welding area it contacts, reducing the thermal expansion effect. After the welding is completed, the electromagnetic plate switches the magnetic direction to generate positive magnetic force to attract the magnet block, prompting the electromagnetic plate to adsorb the detection pen back into the detection tube, completing the current welding point.

[0020] When welding, the hollow adsorption ring will come into contact with the welding area. The cooling oil in the inner cavity can quickly absorb and conduct the heat of the welding area under the instantaneous high temperature of welding, which has the effect of instant cooling, so that the temperature of the welding area can be quickly reduced, the range of the heat-affected zone is reduced, and the thermal deformation of the metal sheet is effectively suppressed, avoiding the high temperature generated during the welding process that will cause local thermal expansion of the support plate, thereby improving the welding quality and production efficiency, and ensuring the stability and accuracy of the traffic sign bracket welding.

[0021] The cooling oil is pumped from the inside of the hollow adsorption ring to the cold exchanger through the circulation pipe, and the temperature of the cooling oil is reduced by the cold exchanger. The cooled cooling oil is returned to the hollow adsorption ring through the circulation pipe to form a closed circulation system, which continuously provides cooling effect for the welding area. The cooling oil in the fixed tube detection pen can also be pumped into the hollow adsorption ring and circulated and cooled together with the cooling oil in the hollow adsorption ring.

The inner cavity of the fixed cylinder 1002 is connected, and the other end is connected to the fixed plate 1004. The fixed plate 1004 applies a certain pressure to the bracket connecting plate through the telescopic rod 1003 and the spring 1005 to ensure that the welding area maintains good contact with the electrode of the welding cylinder 7, and at the same time helps to reduce the vibration of the bracket connecting plate during the welding process, improve the stability and quality of welding, and the elasticity of the spring 1005 can automatically adjust the pressure of the fixed plate 1004 on the bracket connecting plate to adapt to bracket connecting plates of different thicknesses or under different welding conditions, ensuring that the pressure is neither too large nor too small.

[0038] The adsorption member 801 includes a negative pressure fan 802 fixedly mounted on the upper surface of the short plate 1001, a connecting pipe 803 is arranged on the outer surface of the negative pressure fan 802, a plurality of adsorption tubes 804 are arranged in an array inside the hollow adsorption ring 8, the adsorption tubes 804 and the connecting tubes 803 are fixedly connected, a cooler 805 is arranged on the outer surface of the connecting tube 803, a placement groove 12 is provided on the outer surface of the workbench 1, a feeding member is arranged on the outer surface of the workbench 1, the feeding member includes a conveying track, a vibration plate, a pneumatic or electric drive device, and a precise positioning and guiding system, to ensure that the welding material can be accurately delivered to the predetermined position of the welding tube 7, to avoid manual placement of the welding material, which increases the working time and is prone to cause harm to the staff due to the high temperature of the welding tube 7.

[0040] Embodiment 2:

The welding cylinder 7 is a key tool in the welding equipment for converting electrical energy into heat energy to melt metal for welding. The welding cylinder 7 includes a guide The nozzle, cooling system, insulating sleeve, protective cover and other components, the detection part 9 is arranged in the inner cavity of the hollow adsorption ring 8, the inner cavity of the hollow adsorption ring 8 is provided with two detection tubes 901, the inner cavities of the detection tubes 901 are fixedly connected with electromagnetic plates 902, the inner cavity of the detection tubes 901 is provided with a detection pen 904, the lower end of the detection pen 904 is provided with a strip hole, the strip hole is provided with a matching strip flexible membrane 908, the detection pen 904 is provided with a hard arc plate 903, and the hard arc plate 903 is located above the strip flexible membrane 908.

[0042] Specifically, the detection pen 904 and the strip flexible membrane 908 constitute a hollow cylindrical structure, and the inner cavity of the hollow adsorption ring 8 and the hollow cylindrical structure is filled with cooling oil 11. The cooling oil 11 is a liquid medium specially used in the industrial cooling process to control and reduce the working temperature, prevent overheating, extend equipment life, and improve work efficiency and product quality. The use of cooling oil 11 is based on its good thermal conductivity and lubrication properties. It can absorb and take away excess heat in a high temperature environment, thereby reducing the heat affected zone, avoiding thermal deformation of welds, and improving welding quality and production efficiency.

[0043] A circulation pipe 19 is provided on the outer surface of the cooling oil 11, and a cold exchanger 20 is provided on the outer surface of the circulation pipe 19. The circulation pipe 19 is responsible for leading the cooling oil 11 out of the welding area and sending it to the cold exchanger 20 for cooling. The cold exchanger 20 removes heat from the cooling oil 11 through heat exchange to reduce the temperature of the cooling oil 11. A sensor 18 is provided at the end of the detection pen 904 away from the cooling oil 11. The sensor 18 includes a pressure sensor 18, etc., which can monitor pressure changes during welding, help identify welding defects, such as leaking welds or cold welds, and ensure welding quality.

[0044] A fixed tube is arranged between the inner cavity of the detection pen 904 and the hollow adsorption ring 8, a magnet block 905 is fixedly connected to the outer surface of the detection pen 904, the electromagnetic plate 902 and the magnet block 905 are magnetically connected, two movable holes 17 are provided inside the welding tube 7, the detection pen 904 is slidably connected to the inner wall of the movable hole 17, a slide rail 906 is provided in the inner cavity of the detection tube 901, a slider 907 is slidably connected inside the slide rail 906, the slider 907 is fixedly connected to the detection pen 904, and the strip flexible membrane 908 and the rigid arc plate 903 form a circular ring.

[0045] Furthermore, the electromagnetic plate 902 is started to generate a negative magnetic force, so that the negative magnetic force repels the magnet block 905 in the detection pen 904, and the detection pen 904 is prompted to move outward along the slide rail 906 through the slider 907 until the detection pen 904 contacts the bolt, thereby achieving accurate positioning and fixation of the bolt, ensuring its stability during the welding process. During welding, the detection pen 904 and the internal sensor 18 monitor the welding status in real time to avoid the occurrence of welding leaks. At the same time, the rigid arc plate 903 increases the weight of the detection pen 904 to move it downward, so that the strip flexible membrane 908 under the detection pen 904 contacts the welding The welding area is in contact with each other, so that the cooling oil 11 in the inner cavity of the detection pen 904 can instantly cool the welding area it contacts. Through the circulation pipe 19, the cooling oil 11 can be pumped from the inside of the hollow adsorption ring 8 to the cold exchanger 20 to take away the heat and reduce the temperature of the cooling oil 11. The cooled cooling oil 11 is returned to the hollow adsorption ring 8 through the circulation pipe 19 to form a closed circulation system, which continuously provides a cooling effect for the welding area. Through the fixed pipe, the cooling oil 11 in the detection pen 904 can also be pumped into the hollow adsorption ring 8, and circulated and cooled together with the cooling oil 11 in the hollow adsorption ring 8.

[0046] The working principle of the present invention is to place the bracket connecting plate to be welded on the placement groove 12 of the workbench 1, and ensure that the position of the bracket connecting plate is accurate. At this time, the connecting plate 14 on the threaded rod 13 is driven downward along the thread by rotating the handle, so that the pressure plate 15 presses the bracket connecting plate to ensure that the bracket connecting plate will not be displaced or warped due to welding thermal stress during welding, thereby ensuring the stability of the welding process. The welding material is transported into the welding cylinder 7 using a feed piece, and the electric slide bar 3 and the electric push rod 5 are started to adjust the position of the welding cylinder 7 so that its front end is accurately aligned with the welding point, and then the welding cylinder 7 is turned on to generate an arc or capacitor discharge to start the welding process. The spring 1005 and the telescopic rod 1003 cooperate with each other to ensure that the fixed plate 1004 is in close contact with the welding area, and downward pressure is applied to the bracket connecting plate. At the same time, the bracket can be pressed by the fixed plate 1004 The connecting plate is fixed, and at the same time, the negative pressure fan 802 is started to work, so that the negative pressure fan 802 draws the vacuum into the adsorption tube 804 through the connecting tube 803 and the adsorption tube 804, forming a negative pressure environment. This negative pressure produces an upward adsorption force on the connecting plate, which forms a balance with the downward pressure exerted by the fixed plate 1004, further stabilizing the bracket connecting plate to prevent it from warping or deformation during the welding process. The two forces work together to effectively control the thermal deformation during the welding process and ensure the stability and welding quality of the welding point. At the same time, the cooler 805 on the surface of the connecting tube 803 converts the negative pressure gas circulating in the adsorption tube 804 into cold air. When the cold air passes through the inner cavity of the adsorption tube 804, the cooling oil 11 can be cooled to ensure that the cooling oil 11 maintains a low temperature during the circulation process, improve the cooling efficiency, and further reduce the thermal deformation during the welding process.

[0047] When the welding material (welding wire) enters the welding tube 7, the electromagnetic plate 902 is activated to generate a negative magnetic force, so that the negative magnetic force repels the magnet block 905 in the detection pen 904, prompting the detection pen 904 to move outward along the slide rail 906 through the slider 907 until the detection pen 904 contacts the welding material to ensure its stability during the welding process. During welding, the detection pen 904 and the internal sensor 18 monitor the welding status in real time to ensure the accuracy of the welding parameters. At the same time, the rigid arc plate 903 increases the weight of the detection pen 904 to make it move downward, thereby making the strip flexible membrane 908 under the detection pen 904 It contacts the welding area so that the cooling oil 11 in the inner cavity of the detection pen 904 can instantly cool the welding area it contacts to reduce the thermal expansion effect. After welding is completed, the data of the sensor 18 can be used to evaluate the welding quality. The detection pen 904 avoids welding leaks during contact with the welding material. When the welding is completed, the electromagnetic plate 902 switches the magnetic direction to generate positive magnetic force, which attracts the magnet block 905, so that the electromagnetic plate 902 absorbs the detection pen 904 back into the detection tube 901 and detaches from the moving hole 17. After completing the current welding point, the position of the welding tube 7 is adjusted to prepare for the next welding point.

[0048] Subsequently, during welding, the hollow adsorption ring 8 will come into contact with the welding area. The cooling oil 11 in the inner cavity can quickly absorb and conduct the heat of the welding area under the high temperature at the moment of welding, thereby achieving an instant cooling effect, so that the temperature of the welding area can be rapidly reduced, the range of the heat-affected zone is reduced, and the thermal deformation of the connecting plate is effectively suppressed, so as to avoid the high temperature generated during the welding process causing local thermal expansion of the bracket connecting plate. At the same time, the cooling oil 11 can be pumped from the inside of the hollow adsorption ring 8 to the cold exchanger 20 through the circulation pipe 19. The high-temperature cooling oil 11 sent from the circulation pipe 19 is heat exchanged through the cooling medium such as the refrigerant or cooling water in the cold exchanger 20, and the heat is taken away, so that the temperature of the cooling oil 11 is reduced. The cooled cooling oil 11 is returned to the hollow adsorption ring 8 through the circulation pipe 19 to form a closed circulation system, which continuously provides a cooling effect for the welding area. The cooling oil 11 in the detection pen 904 can also be pumped into the hollow adsorption ring 8 through the fixed pipe, and circulated and cooled together with the cooling oil 11 in the hollow adsorption ring 8 to ensure that the temperature of the entire welding area is effectively controlled.
