Description

Technical Field

[0001] This invention relates to the field of welding technology, and in particular to a welding fixture for a generator set base housing. Background Technology

[0002] A generator set is a complete set of mechanical equipment that converts other forms of energy into electrical energy. It consists of a power system, a control system, a noise reduction system, a vibration damping system, and an exhaust system. It is driven by a water turbine, a steam turbine, a diesel engine, or other power machinery. It converts the energy generated by water flow, air flow, fuel combustion, or nuclear fission into mechanical energy, which is then transferred to the generator. The generator then converts the mechanical energy into electrical energy, which is then output to electrical equipment. Generator sets generate huge vibrations when they are working, so the outer shell and the base need to be welded and fixed together; otherwise, the equipment will be damaged.

[0003] During the welding of the outer shell and the base, the outer shell is difficult to clamp due to its arc shape. Unstable clamping can easily lead to welding deviation, resulting in unstable welding of the outer shell and the base and affecting subsequent work. In addition, the straight-line fit between the outer shell and the base requires grinding and rust removal before welding due to the long straight-line distance, and cleaning of weld slag after welding. If pre-processing and post-processing cleaning are not done, the welding effect will be affected, resulting in an unstable weld. The arc-shaped fit between the outer shell and the base requires a high level of welding skill from the workers. Moreover, due to the large size of the outer shell, other height-lifting equipment is needed to assist workers in moving and welding, which is extremely inconvenient and makes it difficult to guarantee the welding quality.

[0019] Please see Figures 1 to 10A welding fixture for a generator set base housing according to the present invention includes a welding table 100, a conveyor belt 110, a grinding and clamping assembly 200, a welding assembly 300, a driving assembly 400 for driving the welding assembly 300, a cleaning assembly 500, and a connecting rod 120. The conveyor belt 110 is located at the center of the upper end of the welding table 100. A plurality of positioning blocks 111 are provided on the conveyor belt 110. A base 130 is provided on the positioning block 111. A housing 140 is provided at the upper end of the base 130. Two grinding and clamping assemblies 200 are located on both sides of the front end of the welding table 100. The welding assembly 300 is located on the rear side of the grinding and clamping assembly 200. The driving assembly 400 is located on the rear side of the welding assembly 300. The cleaning assembly 500 is located at the end of the welding table 100. One end of the connecting rod 120 is connected to the grinding and clamping assembly 200, and the other end of the connecting rod 120 is connected to the cleaning assembly 500. The positioning block 111 serves a quick positioning function, allowing users to quickly place the base 130 at the appropriate position on the conveyor belt 110. The grinding and clamping assembly 200 serves to clamp the base 130 and the outer shell 140 and to remove rust. The welding assembly 300 serves to weld the base 130 and the outer shell 140. The cleaning assembly 500 serves to clean the welding slag produced during welding.

[0020] Furthermore, when a user needs to perform welding operations on the base 130 and the outer shell 140 using a welding fixture for a generator base housing according to the present invention, firstly, the user quickly positions the base 130 on the conveyor belt 110 using the positioning block 111, and then places the outer shell 140 on the base 130. The conveyor belt 110 is then started, moving the base 130 and the outer shell 140. The grinding and clamping assembly 200 then begins operation, clamping the base 130 and the outer shell 140 and simultaneously cleaning rust. When the front ends of the base 130 and the outer shell 140 move below the welding assembly 300, the conveyor belt 110 is turned off, and the drive assembly 400 is started. The drive assembly 400 operates, and the welding assembly 300 operates. The welding assembly 300 first aligns the arc-shaped contact points on the front sides of the base 130 and the outer shell 140. After welding is completed, drive assembly 400 is turned off, welding assembly 300 continues to work, conveyor belt 110 is started to complete the welding work at the straight joint of the base 130 and the outer shell 140. Drive assembly 400 is started again, conveyor belt 110 is turned off, welding assembly 300 continues to work to complete the welding work at the arc joint of the base 130 and the rear side of the outer shell 140. After that, drive assembly 400 is turned off, welding assembly 300 continues to work, conveyor belt 110 moves backward to complete the welding work at the straight joint of the base 130 and the outer shell 140 on the other side. After all welding work is completed, welding assembly 300 and drive assembly 400 are turned off, conveyor belt 110 moves forward to push the welded base 130 and outer shell 140 to cleaning assembly 500. Cleaning assembly 500 works to clean up the welding slag generated during welding.

[0021] In this embodiment, a plurality of positioning blocks 111 are provided on the conveyor belt 110, a base 130 is provided on the positioning block 111, and a shell 140 is provided on the upper end of the base 130. The user can quickly place the base 130 on the conveyor belt 110 using the positioning block 111, and then place the outer shell 140 on top of the base 130. After that, the user starts the conveyor belt 110, which moves the base 130 and the outer shell 140 forward.

[0022] In this embodiment, the grinding clamping assembly 200 includes: a first bracket 210, a bottom clamping plate 220, a first slide rod 230, a rotating rod 240, a second slide rod 250, a first mounting platform 251, a grinding drive motor 252, a rust-removing grinding wheel 253, a third slide rod 260, a first telescopic rod 261, and an arc-shaped clamping plate 262. The first bracket 210 is disposed on the front side of the welding table 100. The first slide rod 230 is slidably disposed on the inner side of the first bracket 210. The bottom clamping plate 220 is fixedly connected to one end of the first slide rod 230. The rotating rod 240 is rotatably connected to the other end of the first slide rod 230. The second slide rod 250 is disposed above the first slide rod 230 and is fixedly connected to the rotating rod 240. The first mounting platform 251 is disposed at the front end of the second slide rod 250. The rust-removing grinding wheel 253 is disposed on the first mounting platform 251. The output of the grinding drive motor 252 is... The end is connected to the rust-removing grinding wheel 253. The third slide rod 260 is positioned above the second slide rod 250. The third slide rod 260 is fixedly connected to the rotating rod 240. The first telescopic rod 261 is fixedly positioned at the front end of the third slide rod 260. The arc-shaped clamping plate 262 is fixedly connected to the first telescopic rod 261. The clamping end face of the arc-shaped clamping plate 262 is provided with clamping protrusions. The side of the bottom clamping plate 220 is chamfered. The fan 270 is provided with... The first support 210 is located on the right side of the first support 210. The first support 210 is provided with a rust remover tank 254. The second slide rod 250 passes through the rust remover tank 254. The second slide rod 250 is provided with a water inlet 255. The front end of the second slide rod 250 is provided with a rust remover spray nozzle 256. The second slide rod 250 is provided with an inclined plate 257 inside. The inclined plate 257 is inclined from the end away from the rust remover spray nozzle 256 to the end close to the rust remover spray nozzle 256. When the conveyor belt 110 moves the outer casing 140 and the base 130 to the bottom clamping plate 220, the bottom end of the base 130 touches the bottom clamping plate 220. The bottom end of the base 130 pushes the first sliding rod 230 to slide inward toward the inside of the first bracket 210 until the bottom clamping plate 220 moves to a position where it is in contact with the bottom end of the base 130. At this point, the clamping effect on the base 130 is achieved. Since the rotating rod 240 is rotatably connected to the first bracket 210, when the first sliding rod 230 slides inward toward the inside of the first bracket 210, the rotating rod 240... The first support 210 rotates outward, causing the second slide bar 250 and the third slide bar 260 to slide outward. The third slide bar 260 moves the arc-shaped clamping plate 262 outward. Then, the top of the outer shell 140 touches the arc-shaped clamping plate 262, and the first telescopic rod 261 retracts. The first telescopic rod 261 moves the arc-shaped clamping plate 262 until it is in contact with the outer shell 140, thus achieving the clamping effect on the outer shell 140. The first bracket 210 provides a fixed support. The chamfered edges on the side of the bottom clamping plate 220 facilitate the base 130 pushing the first slide rod 230 inward. The clamping protrusions on the arc-shaped clamping plate 262 better clamp the arc-shaped outer shell 140. When the second slide rod 250 slides outward from the first bracket 210, it drives the rust-removing grinding wheel 253 to the point where the outer shell 140 and the base 130 are in direct contact. This activates the grinding drive motor 252, which rotates the rust-removing grinding wheel 253. Rust removal is performed at the straight joint. Simultaneously, the water inlet 255 on the second slide rod 250 enters the rust removal liquid tank 254. The rust removal liquid in the rust removal liquid tank 254 flows into the second slide rod 250 through the water inlet 255. The rust removal liquid spray nozzle 256 is activated to spray out the rust removal liquid to assist in rust removal. In addition, by setting the inclined plate 257, the rust removal liquid flows to the rust removal liquid spray nozzle 256 more easily due to gravity, making it easier to spray out the rust removal liquid. Since high temperatures are generated during rust removal and grinding, the fan 270 can be set to reduce the temperature, which is convenient for subsequent welding work.

[0023] In this embodiment, the welding assembly 300 includes: a welding fixing plate 310, an arc-shaped guide groove 320, a first guide wheel 330, a second guide wheel 340, a welding head 350, a cylinder 360, an output shaft 370, a first support rod 380, and a second support rod 390. The arc-shaped guide groove 320 is fixedly disposed on the right side of the first bracket 210. The first guide wheel 330 is disposed on one side of the welding fixing plate 310 and is rotatably disposed within the arc-shaped guide groove 320. Two second guide wheels 340 are disposed on the first guide wheel 330. On the upper and lower sides of the 0, two second guide wheels 340 are rotatably disposed on the outer side of the arc-shaped guide groove 320. The cylinder 360 is disposed on the other side of the welding fixing plate 310. One end of the output shaft 370 is connected to the output end of the cylinder 360, and the other end of the output shaft 370 is connected to the welding head 350. Two first support rods 380 and two second support rods 390 are disposed on both sides of the cylinder 360. One end of the first support rod 380 is rotatably disposed on the welding fixing plate 310, and the other end of the first support rod 380 is connected to the welding head 350. One end of the second support rod 390 is rotatably connected, and the other end of the second support rod 390 is fixedly connected to the output shaft 370. The drive assembly 400 includes: a second bracket 410, a swing drive motor 420, a crank 430, a push shaft 440, a gear table 450, a gear 460, a support frame 470, and a swing rod 480. The second bracket 410 is disposed on the right side of the arc-shaped guide groove 320. The swing drive motor 420 is disposed on the second bracket 410. The crank 430 is connected to the output end of the swing drive motor 420. The push shaft 440... One end of the push shaft 440 is connected to the crank 430, and the other end of the push shaft 440 is connected to the gear platform 450. The gear platform 450 is slidably mounted on the second bracket 410. The gear 460 meshes with the tooth groove on the gear platform 450. The gear 460 is rotatably connected to the support frame 470. The swing rod 480 is eccentrically mounted on the gear 460. The swing rod 480 has a sliding groove 481. The swing rod 480 is slidably connected to the first guide wheel 330. The middle part of the gear platform 450 has a tooth groove, and the two sides of the gear platform 450 have no tooth grooves. The process involves starting the swing drive motor 420, which in turn rotates the crank 430. The crank 430 then drives the push shaft 440 to slide left and right, which in turn drives the gear table 450 to slide left and right. As the gear table 450 slides left and right, it drives the gear 460 to rotate, which in turn drives the swing rod 480 to rotate. Because the gear table 450 only has toothed grooves in its middle section, these grooves can only support the gear 460 to rotate 180°. When the push shaft 440 drives the gear table 450 to move to the left, the gear table... The drive gear 460 rotates clockwise, causing the swing rod 480 to rotate clockwise from one side of the arc-shaped guide groove 320 to the other. When the push shaft 440 drives the gear table 450 to move to the right, the gear table 450 drives the gear 460 to rotate counterclockwise, causing the swing rod 480 to rotate counterclockwise from one side of the arc-shaped guide groove 320 to the other. When the swing rod 480 rotates, the first guide wheel 330 is slidably disposed in the groove 481 in the swing rod 480, causing the swing rod 480 to drive the first guide wheel. The first guide wheel 330 slides along the arc-shaped guide groove 320, driving the welding fixing plate 310 to slide along the arc-shaped guide groove 320. The second guide wheel 340 assists in the sliding of the welding fixing plate 310. The cylinder 360 is activated, driving the output shaft 370 to move. The output shaft 370 drives the welding head 350 to move. By moving the welding head 350, the welding distance can be easily changed, which can better realize the welding function. When the output shaft 370 moves, it will drive the second support rod 390 to rotate. The first support rod 380 is driven to rotate. Stability can be ensured by setting the first support rod 380 and the second support rod 390. When the conveyor belt 110 transports the outer shell 140 and the base 130 to the welding assembly 300, the conveyor belt 110 is turned off, and the swing drive motor 420 and the cylinder 360 are started at the same time. The swing drive motor 420 drives the crank 430 to rotate in a circle at the upper end. The crank 430 drives the push shaft 440 to slide to the left. The push shaft 440 drives the gear table 450 to slide to the left. The gear table 450 drives the gear 460 to rotate clockwise.

One end of the hose 581 is connected to the water tank 580, and the other end of the hose 581 is connected to the clean water spray nozzle 582. When the conveyor belt 110 moves the outer casing 140 and the base 130 to the bottom clamping plate 220, the bottom end of the base 130 touches the bottom clamping plate 220. The bottom end of the base 130 pushes the first slide rod 230 to slide inward toward the inside of the first bracket 210. The first slide rod 230 pushes the fourth slide rod 520 to slide inward toward the inside of the third bracket 510 through the connecting rod 120.

The inner side slides, and at the same time the second telescopic rod 540 is activated to adjust the height of the third mounting platform 550 so that the slag grinding wheel 570 and the clean water spray nozzle 582 are in a position that is convenient for cleaning slag. When the conveyor belt 110 moves the outer shell 140 and the base 130 to the cleaning component 500, the cleaning drive motor 560 is activated. The cleaning drive motor 560 drives the slag grinding wheel 570 to rotate. The slag grinding wheel 570 begins to clean the slag produced by welding. At the same time, the clean water spray nozzle 582 is activated to draw clean water from the water tank 580 through the hose 581 into the clean water spray nozzle 582 and spray the clean water out to assist the slag grinding wheel 570 in cleaning the slag.

The conveyor belt 110 is located at the center of the upper end of the welding table 100. Two grinding and clamping assemblies 200 are located on both sides of the front end of the welding table 100. The welding assembly 300 is located on the rear side of the grinding and clamping assembly 200. The drive assembly 400 is located on the rear side of the welding assembly 300. The cleaning assembly 500 is located at the end of the welding table 100. One end of the connecting rod 120 is connected to the grinding and clamping assembly 200. The other end of 20 is connected to the cleaning component 500. During operation, the user quickly positions the base 130 on the conveyor belt 110 using the positioning block 111, and then places the outer shell 140 on the base 130. The conveyor belt 110 is then started, moving the base 130 and the outer shell 140. When the conveyor belt 110 moves the outer shell 140 and the base 130 to the bottom clamping plate 220, the first slide rod 230, the second slide rod 250, the third slide rod 260, the fourth slide rod 520, and the connecting rod 120 work together to achieve the clamping function of the arc-shaped clamping plate and the bottom clamping plate 220. The rust remover flows into the second slide rod 250 and is sprayed out through the rust remover spray nozzle 256, simultaneously grinding the rust remover... The rust-removing grinding wheel 253 and the slag-removing grinding wheel 570 are moved to a suitable position for operation. The rust-removing grinding wheel 253 completes the rust removal work. Then, when the conveyor belt 110 moves the outer shell 140 and the base 130 to the welding assembly 300, the conveyor belt 110 stops working, and the welding assembly 300 starts working. The drive assembly 400 drives the welding head 350 to rotate along the arc-shaped guide groove 320 to complete the welding of the arc-shaped contact area on the front side between the base 130 and the outer shell 140. Then, the drive assembly 400 stops working, and the conveyor belt 110 continues to move the outer shell 140 and the base 130. The welding head 350 continues to work to complete the welding of the straight contact area on the side side between the base 130 and the outer shell 140. Then, the conveyor belt 110 stops working, and the drive assembly 400 starts working. The process begins with the drive assembly 400 rotating in the opposite direction along the arc-shaped guide groove 320 to complete the welding of the rear arc-shaped contact area between the base 130 and the outer shell 140. Afterwards, the drive assembly 400 stops working, the conveyor belt 110 moves in the opposite direction, and the welding head 350 continues working to complete the welding of the straight contact area on the other side between the base 130 and the outer shell 140. Then, the conveyor belt 110 moves forward, causing the outer shell 140 and the base 130 to continue moving forward. The cleaning assembly 500 starts working, the slag grinding wheel 570 cleans the welding slag produced during welding, and simultaneously, the clean water spray nozzle 582 sprays clean water to assist in cleaning. The generator set base outer shell welding fixture of this invention facilitates the clamping of the outer shell 140 and the base 130 through the mutual cooperation of various structures.This also ensures both the straight-line fit and the arc-shaped fit between the base 130 and the outer shell 140 during welding. Furthermore, it allows for simultaneous pre-welding grinding and rust removal, as well as post-weld slag cleaning, further guaranteeing the welding quality.
