Description

Technical Field

[0001] The present invention relates to the field of welding technology, in particular to high-efficiency pulse arc welding positioning tooling equipment for busbar production. Background Art

[0002] The busbar is a device used in power supply systems and is commonly found in railways, trams, subways, and other rail transit systems. During busbar production, a grounding flat steel bar must be assembled. The grounding flat steel bar is a key safety component in busbar systems. Its primary function is to provide electrical grounding for the busbar, ensuring that in the event of equipment failure or current leakage, the system can safely discharge current and prevent dangerous situations such as electric shock. The grounding flat steel bar is usually connected to the metal parts of the busbar system and buried in the ground, connected to the ground grounding system.

[0003] The grounding flat steel needs to be extended according to the different equipment layout, the scope of the grounding system or the limitations of the construction site. In the process of extending the grounding flat steel, pulse arc welding is required to weld and extend the grounding flat steel. For example, welding is performed by a clean plate reinforcement welding equipment disclosed in publication number CN117943661B. However, in the process of welding the grounding flat steel and the extension section, the grounding flat steel and the extension section need to be kept horizontal. Keeping the grounding flat steel and the extension section horizontal can help improve welding quality, reduce deformation, avoid stress concentration, ensure the uniformity of the weld, and thus ensure the stability and reliability of the grounding system. The current pain points in construction are concentrated on the lack of positioning tooling function. Since conventional equipment lacks multi-directional adjustment functions, if the operator finds horizontal deviation after fixing the grounding flat steel, the workpiece must be completely disassembled and repositioned. This repeated disassembly and assembly not only wastes labor time, but is also likely to cause material deformation due to multiple clamping and fixation, affecting the conductivity and mechanical strength of the grounding system. Summary of the Invention

[0032] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0033] The present invention will be further described below with reference to the embodiments.

[0034] Example: Refer to Figures 1 to 10 , high-efficiency pulse arc welding positioning tooling equipment for busbar production, including:

[0035] Base plate 1, the upper end surface of the base plate 1 is fixedly installed with a two-dimensional driving device 101, the driving end of the two-dimensional driving device 101 is fixedly installed with a fixed head 102, and a pulse arc welding gun 103 is fixedly installed in the fixed head 102. The pulse arc welding gun 103 is connected to a welder. Pulse arc welding is a method of welding by adjusting current pulses, which can provide higher welding quality and precision. Its working principle is to control the current to change between two high and low pulse stages to reduce heat input and spatter, thereby improving the welding effect. It is especially suitable for thin plate and high-precision welding. The pulse arc welding system consists of a pulse arc welding gun 103 and a welder. The pulse arc welding gun 103 guides the arc and feeds shielding gas, and the welder provides pulse current and controls the welding process by precisely adjusting the intensity and frequency of the current. The advantages of pulse arc welding include reducing thermal deformation and improving welding quality and precision. The pulse arc welding gun 103 is the part that contacts the workpiece in pulse arc welding. Its main functions are to guide the arc, supply shielding gas, and feed welding wire. The welder is one of the core equipment of pulse arc welding and provides the current source required for welding. The pulse welding machine can provide pulse current output and can accurately control the waveform, frequency and amplitude of the current during the welding process;

[0036] The horizontal positioning assembly 2 includes two placement blocks 201 fixed to the upper end surface of the base plate 1. Two pairs of first support columns 205 are symmetrically arranged inside the two placement blocks 201. The first support columns 205 are driven to rise and fall inside the placement blocks 201. Two second support columns 227 are arranged on both sides of the placement blocks 201. The second support columns 227 are driven to rise and fall on both sides of the placement blocks 201. A slot 208 is opened in the placement block 201. Two air bags 214 are arranged in the slot 208. A pressure detection element is fixedly installed on the inner wall of the air bag 214. The pressure detection element is electrically connected to the controller. The pressure detection element can use an existing pressure sensor. The pressure sensor usually uses a strain gauge, piezoelectric material or capacitance change to sense the change in pressure and convert it into an electrical signal;

[0037] The fixing assembly 3 includes an extrusion rotating column 308 arranged above the placement block 201.

[0038] It should be noted that the thickness of the grounding flat steel is roughly consistent with the thickness of the extension section, and the thickness of the extension section cannot be lower than the thickness of the grounding flat steel. The purpose of the busbar grounding system is to provide a low-impedance current path. If the extension section is thinner than the original grounding flat steel, it will cause the local current density to increase, increase the contact resistance, affect the grounding effect, and may even cause overheating or damage.

[0039] Reference Figures 3 to 10, two pairs of inflatable boxes 202 are embedded in the placement block 201, and a lifting piston plate 203 is airtightly and slidingly installed on the inner wall of the inflatable box 202. A lifting rod 204 is fixedly installed on the upper end surface of the lifting piston plate 203. The upper end of the lifting rod 204 passes through the inflatable box 202 and is integrally formed with a tray. The inner wall of the tray is rotatably connected to the first support column 205. A first spring 207 is fixedly installed between the tray and the inflatable box 202. A three-way pipe 206 is embedded in the placement block 201. The three-way pipe 206 has two output ends and one input end. The output end is respectively connected to each inflatable box 202, and the input end is connected to an air pump. The air pump is an existing device, a device for pressing air or other gas from one place to another. The slot 208 A linear drive device 209 is fixedly installed at the inner bottom end. The linear drive device 209 is an existing device, which is a mechanical device that converts rotational motion into linear motion. The linear drive device 209 is electrically connected to the controller. A moving seat 210 is fixedly installed at the driving end of the linear drive device 209. A telescopic rod 211 is fixedly installed at the inner bottom end of the moving seat 210. A disc 213 is fixedly installed on the upper end surface of the telescopic rod 211. A second spring 212 is fixedly installed between the disc 213 and the moving seat 210. The upper end surface of the disc 213 is fixedly connected to the airbag 214. A partition 215 is fixedly installed on the upper end surface of the disc 213 and between the airbags 214. When the grounded flat steel and the extension section are placed above the placement block 201, the grounded flat steel and The extension section will squeeze the airbag 214 and the partition 215, so that the airbag 214 and the partition 215 drive the telescopic rod 211 to contract and compress the second spring 212, and the airbag 214 and the partition 215 will drop into the slot 208. After the grounding flat steel and the extension section are welded, the compressed second spring 212 will drive the airbag 214 and the partition 215 to rise. It should be noted that in the process of the grounding flat steel and the extension section squeezing the airbag 214, the air pressure change in the airbag 214 makes the electrical signal generated by the pressure detection element not exceed the preset value. An L-shaped clamping rod 216 is slidably installed in the two placement blocks 201. The lower end of the L-shaped clamping rod 216 passes through the bottom plate 1. The opposite side of the L-shaped clamping rod 216 is staggered with tooth plates 217. The bottom plate 1 A vertical plate 218 is symmetrically installed on the lower end surface of the vertical plate 218, and a rotating tooth 219 is rotatably installed on the opposite side of the vertical plate 218. The rotating tooth 219 engages with the tooth plate 217. A first external block 220 is fixedly installed on the opposite side of the vertical plate 218, and a second external block 221 is fixedly installed on one side of the L-shaped clamping rod 216. A third spring 222 is fixedly installed between the first external block 220 and the second external block 221. One of the L-shaped clamping rods 216 is fixedly installed with an inclined plate 223 on the side away from the vertical plate 218. Two pairs of fixed boxes 224 are fixedly installed on both sides of the placement block 201. A lifting block 225 is slidably installed in the fixed box 224. A linkage rod 230 is fixedly installed on the lower end surface of the lifting block 225. The linkage rod 230 passes through the bottom plate 1 and extends to the bottom.The lifting block 225 is rotatably connected to the second support column 227. The outer wall of the second support column 227 is provided with an oblique groove. An electromagnet 226 is fixedly installed on the side of the lifting block 225 away from the second support column 227. The electromagnet 226 is an existing device that generates a magnetic field by electric current. It is usually composed of a conductive coil and an iron core. Its working principle is based on the physical phenomenon that a magnetic field is generated around the conductor when current passes through the conductor. The electromagnet 226 is electrically connected to the controller. A sliding rod 228 is provided inside the fixed box 224. The upper and lower ends of the sliding rod 228 are rotatably connected to the bottom plate 1 and the fixed box 224 respectively. A fourth spring 229 is fixedly installed between the lifting block 225 and the bottom plate 1. The fourth spring 229 is made of high-carbon steel and has excellent strength and pressure resistance. The lifting block 225 and the second support column 227 can well support the grounding flat steel and the extension section through the fourth spring 229.

[0040] Reference Figures 8 and 9 , an external frame 301 is fixedly installed on one side of the base plate 1 and at a position away from the two-dimensional driving device 101, and a rotating driving member 302 is fixedly installed on the upper end surface of the external frame 301. The rotating driving member 302 is an existing device and can be used with an existing motor. This is an existing mature technology and will not be described in detail here. The output end of the rotating driving member 302 passes through the external frame 301 and is fixedly installed with a threaded rod 303. The threaded rod 303 is rotatably connected to the external frame 301. The outer wall of the threaded rod 303 is threadedly sleeved with a lifting plate 304. The lifting plate 304 is slidably connected to the external frame 301. The lifting heads 306 are rotatably installed inside the two ends of the lifting plate 304. A lifting cross bar 307 is fixedly installed on one side of the head 306, and the lifting cross bar 307 is rotatably connected to the extrusion rotating column 308 inside. Two extrusion plates 311 are fixedly installed on both sides of the lifting plate 304, and two pairs of fixed blocks 309 are symmetrically installed on both sides of the external frame 301. A limiting rod 310 is fixedly installed between the fixed blocks 309, and the limiting rod 310 is slidably connected to the lifting plate 304 and the rotating head 306. A sleeve is fixedly installed on the lower end surface of the fixed block 309, and the sleeve is rotatably connected to the rotating head 306. A coil spring 305 is provided in the sleeve, and the inner and outer ends of the coil spring 305 are fixedly connected to the rotating head 306 and the sleeve respectively. The limiting rod 310 is divided into a hard section and a soft end. Figure 8 As shown, the thicker part is the hard segment and the thinner part is the soft segment. The rotating head 306 will be limited by the hard segment when sliding on the outer wall of the hard segment. When sliding to the outer wall of the soft end, the rotating head 306 can rotate freely, causing the soft segment to bend, and the coil spring will be wound during the rotation of the rotating head 306.

[0041] The working principle of the present invention is as follows:

[0042] By placing the grounding flat steel and the extension section on the upper end surface of the placement block 201, the second support column 227 and the first support column 205 will be supported on the lower ends of the grounding flat steel and the extension section respectively, so that the grounding flat steel and the extension section are supported above the placement block 201 by the second support column 227 and the first support column 205 and maintain a certain distance (the second support column 227 and the first support column 205 respectively support the lower ends of the grounding flat steel and the extension section from both sides to ensure the initial positioning), and the grounding flat steel and the extension section will squeeze the airbag 214 to drive the disc 213 to descend, so that the disc 213 drives the telescopic rod 211 to contract and compress the second spring 212, and open the rotary drive part 302 to drive the lifting plate 304, the lifting cross bar 307 and the extrusion rotating column 308 to descend, and the extrusion rotating column 308 will descend above the second support column 227 and the first support column 205 to contact The grounding flat steel and the extension section, it should be noted that, in the process of squeezing the rotating column 308 to descend and contact the grounding flat steel and the extension section, the squeezing rotating column 308 can cooperate with the second support column 227 and the first support column 205 to fix the grounding flat steel and the extension section respectively on the upper end surface of the placement block 201 (limiting and fixing the grounding flat steel and the extension section), and by opening the linear drive device 209, the movable seat 210 is driven to move in the slot 208, and the movable seat 210 will drive the airbag 214 to move from the lower end surface of the grounding flat steel to the lower end surface of the extension section (or from the lower end surface of the extension section to the lower end surface of the grounding flat steel). In this process, if the weld formed by the connection between the grounding flat steel and the extension section is not horizontally aligned (the grounding flat steel is lower than the extension section or the extension section is lower than the grounding flat steel), the airbag 214 will contact the lower end surface of the extension section, so that the movement of the airbag 214 is hindered (such as Figure 10 As shown, Figure 10 The figure shows the obstructed state of the airbag 214 when the grounded flat steel and the extended section deviate horizontally). The airbag 214 will be squeezed by the lower end of the extended section, and the gas inside the airbag 214 will be compressed, causing the air pressure inside the airbag 214 to increase. After the air pressure increases and exceeds a preset value, the pressure detection element will generate an electrical signal according to the change in the air pressure inside the airbag 214. The controller controls the voltage input to the air pump through the electrical signal generated by the pressure detection element, causing the air pump to start and inject air into the inflation box 202 below the extended section, increasing the air pressure in the inflation box 202. The lifting piston plate 203 slides and rises in the inflation box 202 due to the increased air pressure, driving the first support column 205 to rise and lift the extended section, so that the extended section is kept horizontal with the grounded flat steel.

[0043] It should be noted that after the first support column 205 is driven to rise and lift the extension section to be aligned with the ground flat steel level, the airbag 214 is no longer squeezed by the lower end of the extension section during the movement, and the air pressure inside it returns to its original state. The pressure detection element no longer generates an electrical signal due to the change in the air pressure inside the airbag 214, and stops controlling the voltage input to the air pump. The air pump stops supplying air, and the airbag 214 will continue to be driven to the bottom of the extension section through the linear drive device 209. In the process of the airbag 214 contacting the lower end of the extension section, the partition 215 will separate the two airbags 214 to prevent one of the airbags 214 from squeezing the other airbag 214 when squeezed (the airbag 214 contacts the extension section on one side and is blocked by the partition 215 on the other side during the squeezing process, and the gas inside it will be squeezed). In the process of the pressure detection element generating an electrical signal, the controller will also control the input to the linear drive device 209 The voltage causes the linear drive device 209 to slow down its movement speed, thereby avoiding overload in the process of driving the partition plate 215 and the airbag 214 in contact and extrusion with the lower end of the extension section. When the airbag 214 is driven to move to the lower end surface of the extension section, the linear drive device 209 will drive the airbag 214 to move back and forth to the lower end surface of the grounded flat steel (in the process of aligning the grounded flat steel and the extension section to form a weld, the airbag 214 moves from the lower end of the grounded flat steel to the lower end of the extension section, but the lower end of the extension section is not necessarily lower than the grounded flat steel, and the lower end of the grounded flat steel may be lower than the lower end of the extension section). If the lower end of the grounded flat steel is lower than the lower end of the extension section, the airbag 214 will also contact and squeeze the lower end of the grounded flat steel, and the pressure detection element provided in the corresponding squeezed airbag 214 will generate an electrical signal. The controller will control the voltage input to the air pump through the electrical signal, drive the corresponding first support column 205 to rise, and lift the grounded flat steel so that the grounded flat steel is horizontally aligned with the extension section;

[0044] In the process of the first support column 205 rising and lifting the grounding flat steel or the extension section for alignment, the other end of the grounding flat steel and the extension section is supported by the second support column 227. When the first support column 205 rises and lifts the grounding flat steel and the extension section, the other end of the grounding flat steel and the extension section will drop (the upper end of the grounding flat steel and the extension section is squeezed by the squeezing rotating column 308, one end is lifted by the first support column 205, and the other end will drop). In the process of dropping, the second support column 227 will be squeezed downward, so that the second support column 227 is synchronously lifted and lowered through the linkage rod 230, while the lifting block 225 and the electromagnet 226 slide down and drop on the inner wall of the lifting rod 204. The sliding rod 228 is squeezed. After the first support column 205 rises and lifts the grounding flat steel and the extension section to adjust to the level, the air bag 214 is driven to slide back and forth on the lower end surface of the grounding flat steel and the extension section for several times (the number of reciprocating movements is preferably set to 5 to 10 times). After the air bag 214 is no longer squeezed by the grounding flat steel and the extension section, it indicates that the grounding flat steel and the extension section have been horizontally aligned. The controller controls the voltage input to the electromagnet 226, so that the electromagnet 226 generates a magnetic force to be adsorbed on the inner wall of the fixing box 224, so that the second support column 227 fixes and supports the two ends of the grounding flat steel and the extension section between the fixing box 224 to prevent the grounding flat steel and the extension section from being displaced during welding.

[0045] When welding the grounding flat steel and the extension section, it is necessary to weld the upper and lower long sides first to prevent stress concentration, and then weld the short sides on both sides. By starting the two-dimensional drive device 101, the fixed head 102 and the pulse arc welding gun 103 are driven to move, and the pulse arc welding gun 103 can weld the grounding flat steel and the extension section. After welding the long sides in the above manner (after welding one long side, the grounding flat steel and the extension section can be flipped over by the existing manipulator), the grounding flat steel and the extension section are placed vertically between the placement blocks 201, with one short side facing upward. In this process, the lifting plate 304 is driven to descend by opening the rotary drive member 302, so that the lifting plate 304 drives the extrusion plate 311 to descend and contact and squeeze the inclined plate 223. After being squeezed, the inclined plate 223 drives one of the L-shaped clamping rods 216 to drive the tooth plate 217 to move toward the grounding flat steel and the extension section. The tooth plate 217 will engage with the rotating tooth 219 to drive the rotating tooth 219 to rotate, and the rotating rotating tooth 219 will drive the other tooth plate 21 7 drives the L-shaped clamping rod 216 to move toward the ground flat steel and the extension section. The two L-shaped clamping rods 216 are synchronously driven to move toward the ground flat steel and the extension section to clamp and fix the ground flat steel and the extension section, and position the ground flat steel and the extension section between the placement blocks 201, so as to allow the pulse arc welding gun 103 to weld the short side of the ground flat steel and the extension section. It should be noted that when the lifting plate 304 descends, it will drive the rotating head 306 and the lifting cross bar 307 to descend synchronously, and the rotating head 306 and the lifting cross bar 307 will be rotated. The inner wall of the head 306 will slide down on the outer wall of the limit rod 310, and because there is no grounding flat steel and extension section on the upper end face of the placement block 201, the inner wall of the rotating head 306 will slide to the soft section on the outer wall of the limit rod 310. After sliding to the soft section, the extrusion rotating column 308 and the rotating head 306 will contact the upper end face of the placement block 201 and rotate (bend the soft section) to prevent obstruction of the pulse arc welding gun 103 from welding the grounding flat steel and the short side of the extension section, and at the same time avoid obstruction of the extrusion plate 311 from contacting the inclined plate 223.
