Description

Technical Field

[0001] The invention relates to the technical field of welding equipment, in particular to welding equipment used for a garbage truck loader. Background Art

[0002] In recent years, with the development of garbage disposal technology, garbage trucks have emerged. Garbage trucks with a high degree of mechanization can collect and clean up the huge amount of garbage generated every day in modern cities in a timely manner, alleviating the problem of urban garbage. Therefore, they play a very important role in the field of modern garbage disposal. Garbage trucks are vehicles with highly coordinated structure, hydraulic and electrical control. They are mainly used to collect and transport various garbage. They can compress and crush the loaded garbage to increase its density and reduce its volume, greatly improving the efficiency of garbage collection and transportation. As one of the key components of garbage filling operations, the filler can transfer garbage to the garbage truck body through the filler.

[0003] When transferring garbage into the garbage truck body, the filler rotates to contact the ground and fills the garbage to be collected into the filler. Then the filler resets and transfers the garbage into the garbage truck body. The filler frequently collides with the ground during long-term use and transfers heavy garbage, which can easily cause its structure to deform and cause damage. Therefore, in order to strengthen the structural strength of the filler and extend its service life, reinforcement ribs are usually welded on the bottom of the filler. The welding operation of the filler reinforcement ribs usually needs to be performed on professional welding equipment.

[0004] The existing welding equipment for garbage truck loaders has gradually exposed its shortcomings during use, mainly in the following aspects: First, there is the problem of inconvenient clamping and positioning of the filler and the reinforcement. Specifically, the structure of the filler is relatively specific, and a single clamping method cannot effectively clamp the filler. Therefore, the filler is prone to displacement during welding, affecting the welding of the reinforcement. Secondly, the reinforcement needs to be welded to the filler, so the structure of the reinforcement is also relatively specific. During welding, the welder needs to accurately measure the welding position and mark it, and then hold the corresponding reinforcement and fit it to the marked position of the filler for welding. Therefore, the clamping and positioning process of the reinforcement is not convenient to operate.

[0005] Second, there is the problem of poor continuous processability. Specifically, the reinforcing ribs are divided into horizontal ribs and vertical ribs. When welding several horizontal ribs and vertical ribs, it is necessary to repeat the welding operations mentioned in the first problem point. The reciprocating measurement and marking operations and positioning and fitting operations will lead to interruption of the welding process, which in turn leads to poor continuous processability.

[0006] Third, there is the problem of low degree of welding automation. Specifically, affected by the structure of the filler and the reinforcement itself, the welding trajectory of the welding gun when welding the reinforcement is also relatively specific. Therefore, the existing welding equipment cannot automatically weld the reinforcement and can only be welded by manual welding, resulting in a low degree of welding automation. Manual welding also has the problems of low welding efficiency and low welding accuracy.

[0007] In summary, the prior art obviously has inconveniences and defects in practical use, so it is necessary to improve it. Summary of the invention

[0019] Compared with the prior art, the present invention has the following beneficial effects: 1. When clamping and positioning the filler, use the lifting device to lift the filler onto the roller, the telescopic end of the hydraulic telescopic cylinder contracts, and then drives the positioning shaft and the upper positioning plate to move in the direction close to the filler, until the two positioning shafts are respectively inserted into the two hinge holes on the filler, the telescopic end of the lifting telescopic cylinder contracts, the lifting L-shaped plate, the side baffle and the positioning shaft move downward, and with the cooperation of the roller, the filler rotates until the top of the filler abuts against the upper positioning plate, the telescopic end of the translation telescopic cylinder extends, and then drives the side baffle to move in the direction close to the filler, until the two positioning shafts are respectively inserted into the two hinge holes on the filler, the telescopic end of the lifting telescopic cylinder contracts, and the lifting L-shaped plate, the side baffle and the positioning shaft move downward, and the filler rotates with the cooperation of the roller until the top of the filler abuts against the upper positioning plate, and the telescopic end of the translation telescopic cylinder extends, and then drives the side baffle to move in the direction close to the filler, until the two The side baffles contact the two ends of the loader accordingly, the telescopic end of the electric telescopic cylinder is extended, and the lower positioning plate moves toward the loader until it abuts against the inclined surface at the bottom of the loader, thereby completing the clamping and positioning of the loader. When clamping the transverse ribs, the transverse ribs are placed on the transverse rib support bottom plate, and the two telescopic ends of the first two-way telescopic cylinder are contracted until the two transverse rib clamping plates clamp the transverse ribs. Similarly, when clamping the vertical ribs, the vertical ribs are placed on the vertical rib support bottom plate, and the two telescopic ends of the second two-way telescopic cylinder are contracted until the two vertical rib clamping plates clamp the vertical ribs. When the transverse rib to be welded and the loader are positioned, the telescopic end of the lifting and telescopic cylinder is extended, thereby driving the loader to rise, and the servo motor drives the lower single-threaded screw to rotate, thereby driving the moving plate to slide horizontally until the moving plate slides to the first preset position. At this time, the loader is located above the clamped transverse rib, and the telescopic end of the lifting and telescopic cylinder is contracted, and the loader descends until the bottom of the loader fits with the top of the transverse rib. At this point, the positioning of the transverse rib and the loader is completed. After the transverse rib and the loader are welded, the telescopic end of the lifting and telescopic cylinder is extended again to drive the loader to rise, and the servo motor drives the loader again The movable plate slides horizontally until the movable plate slides to the second preset position. At this time, the filler is located above the clamped vertical rib, the telescopic end of the lifting and telescopic cylinder contracts, and the filler descends until the bottom of the filler fits with the top of the vertical rib, thus completing the positioning of the vertical rib and the filler. The device can quickly clamp the filler and several required transverse ribs and vertical ribs, and has high clamping stability. When welding the transverse ribs or vertical ribs, the transverse ribs or vertical ribs can be quickly positioned and fitted with the corresponding welding position at the bottom of the filler, thereby improving the convenience of clamping and positioning operations for the filler, transverse ribs and vertical ribs. 2. When welding the transverse ribs, the driving motor drives the first single-thread screw to rotate, thereby driving the sliding plate to slide horizontally. With the cooperation of the lifting plate and the guide column, the driven plate starts to move. The motion trajectory of the driven plate is the same as the shape of the guide groove. Driven by the driven plate, the T-shaped seat and the automatic welding gun for the transverse ribs move. During the movement, the nozzle of the automatic welding gun for the transverse ribs automatically welds the position where the transverse ribs and the filler fit. Similarly, when welding the vertical ribs, the control motor drives the second single-thread screw to rotate, thereby driving the sliding block, the lifting seat and the automatic welding gun for the vertical ribs to move. The vertical ribs are automatically The welding gun welds one of the vertical bars during the movement. After the welding of the vertical bar is completed, the telescopic end of the telescopic cylinder is controlled to shrink, thereby driving the vertical bar automatic welding gun to descend and avoid the horizontal bar that has been welded. The sliding block slides horizontally until the vertical bar automatic welding gun moves to the area where the next vertical bar is located. The telescopic end of the telescopic cylinder is controlled to reset, and the sliding block drives the vertical bar automatic welding gun to move, and then welds the next vertical bar. The above welding process is repeated until all the vertical bars are welded. The equipment can weld the horizontal bars and vertical bars to the filler at one time, so the continuous processability is good. 3. The equipment has a high degree of automation. During use, it can not only automatically clamp and position the filler, horizontal reinforcement and vertical reinforcement, but also automatically weld the horizontal reinforcement and vertical reinforcement with fast welding speed and high welding accuracy.

[0035] The working principle of this device is: When clamping and positioning the filler 3, a lifting device is used to lift the filler 3 onto the roller 23 (such as Figure 1 As shown in the figure, the telescopic end of the hydraulic telescopic cylinder 20 contracts, thereby driving the positioning shaft 21 and the upper positioning plate 8 to move toward the direction close to the filler 3, until the two positioning shafts 21 are respectively inserted into the two hinge holes on the filler 3, the telescopic end of the lifting and telescopic cylinder 16 contracts, the lifting L-shaped plate 15, the side baffle 13 and the positioning shaft 21 move downward, and with the cooperation of the roller 23, the filler 3 rotates until the top of the filler 3 abuts against the upper positioning plate 8 (as shown in the figure). Figure 2As shown in the figure, the telescopic end of the translation telescopic cylinder 14 is extended, thereby driving the side baffle 13 to move in the direction close to the filler 3, until the two side baffles 13 contact the two ends of the filler 3, the telescopic end of the electric control telescopic cylinder 10 is extended, and the lower positioning plate 11 moves in the direction close to the filler 3, until it abuts against the inclined surface at the bottom of the filler 3, so that the clamping and positioning of the filler 3 is completed.

The servo motor 19 drives the lower single-tooth screw 6 to rotate, thereby driving the moving plate 17 to slide horizontally until the moving plate 17 slides to the first preset The loader 3 is positioned above the clamped transverse rib 38, the telescopic end of the lifting and telescopic cylinder 16 contracts, and the loader 3 descends until the bottom of the loader 3 fits with the top of the transverse rib 38, and the positioning of the transverse rib 38 and the loader 3 is completed. After the transverse rib 38 and the loader 3 are welded, the telescopic end of the lifting and telescopic cylinder 16 is extended again and drives the loader 3 to rise, and the servo motor 19 drives the moving plate 17 to slide horizontally again until the moving plate 17 slides to the second preset position, and the loader 3 is positioned on the clamped vertical rib 46. The telescopic end of the lifting and telescopic cylinder 16 is retracted, and the filler 3 is lowered until the bottom of the filler 3 is fitted with the top of the vertical rib 46, and the positioning of the vertical rib 46 and the filler 3 is completed. The device can quickly clamp the filler 3 and the required transverse ribs 38 and vertical ribs 46, and the clamping stability is high. When welding the transverse ribs 38 or the vertical ribs 46, the transverse ribs 38 or the vertical ribs 46 can be quickly positioned and fitted with the corresponding welding position of the bottom of the filler 3, which improves the convenience of the clamping and positioning operation of the filler 3, the transverse ribs 38 and the vertical ribs 46; When welding the transverse rib 38, the driving motor 27 drives the first single-thread screw 25 to rotate, thereby driving the sliding plate 28 to slide horizontally. With the cooperation of the lifting plate 24 and the guide column 36, the driven plate 29 starts to move. The movement trajectory of the driven plate 29 is the same as the shape of the guide groove 35. Driven by the driven plate 29, the T-shaped seat 31 and the automatic welding gun 32 for the transverse rib move. During the movement, the nozzle of the automatic welding gun 32 for the transverse rib automatically welds the position where the transverse rib 38 and the filler 3 are fitted. Similarly, when welding the vertical rib 46, the control motor 50 drives the second single-thread screw 43 to rotate, thereby driving the sliding block 53, the lifting seat 52 and the automatic welding gun 44 for the vertical rib to move. The rib automatic welding gun 44 welds one of the vertical ribs 46 during the movement. After the welding of the vertical rib 46 is completed, the telescopic end of the telescopic cylinder 54 is controlled to contract, thereby driving the vertical rib automatic welding gun 44 to descend and avoid the welded transverse rib 38. The sliding block 53 slides horizontally until the vertical rib automatic welding gun 44 moves to the area where the next vertical rib 46 is located. The telescopic end of the telescopic cylinder 54 is controlled to reset, and the sliding block 53 drives the vertical rib automatic welding gun 44 to move, and then welds the next vertical rib 46. The above welding process is repeated until all the vertical ribs 46 are welded. The equipment can weld the transverse rib 38 and the vertical rib 46 to the filler 3 at one time, so the continuous processability is good. The equipment has a high degree of automation. During use, it can not only automatically clamp and position the filler 3, the transverse ribs 38 and the vertical ribs 46, but also automatically weld the transverse ribs 38 and the vertical ribs 46, with high welding speed and high welding accuracy.
