Description

Technical Field

[0001] This invention relates to the field of welding technology, specifically to a welding equipment for assembling a chassis frame of a high-speed engineering vehicle. Background Technology

[0002] As a type of automated metal welding equipment manufactured in the intelligent manufacturing equipment industry, the assembly welding equipment is a dedicated integrated automated welding system suitable for batch processing of long straight butt welds on the main beams, subframe longitudinal beams, and cross beams of chassis vehicles such as dump trucks, tow trucks, highway maintenance engineering vehicles, and heavy-duty transport engineering vehicles.

[0003] Currently, traditional automated welding equipment used for processing straight butt joint sections of the main beams and subframe main beams of high-speed engineering vehicle chassis has limited functionality. It can only perform basic continuous welding operations and lacks an integrated pre-cleaning mechanism. The main beam plates of engineering vehicle chassis undergo multiple processes such as blanking and stamping, factory transfer, open-air storage, and on-site assembly. The areas of the plates to be welded inevitably accumulate light deposits such as dust and rust. If these impurities are not thoroughly removed before welding, the light dust and rust will decompose upon heating, producing a large amount of oxidizing gas, which will continuously penetrate into the molten pool and form dense pores. Damaging the weld's density affects welding quality. Furthermore, existing welding equipment lacks a real-time weld gap detection mechanism, making it impossible to automatically identify the fit gap between two butt workpieces during the entire welding process. Relying solely on manual, rough pre-inspection and sampling results in poor detection accuracy and numerous missed detections. If welding operations are started directly without effective detection of the joint gap, and the workpiece butt gap exceeds the process allowable standard, the molten pool filling volume cannot match the gap width, easily leading to forming defects such as incomplete weld fusion, burn-through, weld depression, and insufficient reinforcement, thus affecting welding quality. Summary of the Invention

[0004] The purpose of this invention is to provide a high-speed engineering vehicle chassis frame welding equipment to solve the problem mentioned in the background art that the existing welding equipment lacks an integrated pre-cleaning mechanism. The main beam plates of the engineering vehicle chassis undergo multiple processes such as blanking and stamping, factory transfer, open-air storage, and on-site assembly. The areas of the plates to be welded inevitably have light deposits such as dust and rust attached. If the above impurities are not thoroughly removed before welding, the light dust and rust will decompose and generate a large amount of oxidizing gas after being heated. This gas will continuously penetrate into the molten pool, forming dense pores, damaging the weld density, and affecting the welding quality.

[0013] Compared with the prior art, the beneficial effects of the present invention are: 1.

Simultaneously, negative pressure is used to immediately suck up impurities, eliminating porosity and slag inclusion defects caused by impurities from the source, thus ensuring welding quality.

[0014] 2.

Areas with gaps that are too large are automatically marked with pigment and the machine is stopped and retreated for repair. Areas with gaps that are too large to weld are sprayed with flux online to break the oxide layer and improve the bonding effect of the weld pool. When hard impurities block the scraper, the fault point can be automatically marked and the welding gun output can be cut off, which facilitates quick location of problems in later maintenance, improves the efficiency of manual maintenance, and improves the continuity of processing and the pass rate of the welded frame.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Example 1: Please refer to Figure 1 - Figure 11A high-speed engineering vehicle chassis frame welding equipment includes a main body 1, a main beam placement platform 4 on the main body 1, a transverse support 5 fixedly connected to the side of the main body 1, a driving component 6 slidably connected to the transverse support 5, a welding torch 7 fixedly connected to the driving component 6, a welding pretreatment mechanism and a testing mechanism fixedly connected to the driving component 6, the welding pretreatment mechanism including a side support 8 fixedly connected to the driving component 6, an air suction pipe 9 fixedly connected to the side support 8, the upper end of the air suction pipe 9 connected to an external vacuum cleaner, and a suction component 11 connected to the lower end of the air suction pipe 9, two limiting rods 16 fixedly connected to the outer side wall of the suction component 11, a cleaning component 13 slidably connected to the two limiting rods 16, a pressing spring 17 sleeved on the outer side wall of the limiting rods 16, a cleaning brush 15 and a hard scraper 14 fixedly connected to the bottom of the cleaning component 13, a support frame 18 fixedly connected to the outer side wall of the cleaning component 13, and a wedge-shaped component 23 fixedly connected to the support frame 18.

[0019] A side storage box 45 and a marking box 40 are fixedly connected to the outer side wall of the suction component 11. Both the side storage box 45 and the marking box 40 are provided with liquid filling ports. A flow tube 20 is connected to the bottom of the marking box 40.

[0020] The bottom of the flow tube 20 is connected to a transfer cavity 21. A first marking tube 19 is connected through the interior of the transfer cavity 21. One end of the first marking tube 19 inside the transfer cavity 21 is slidably connected to a slide tube 29. The end of the slide tube 29 inside the first marking tube 19 is sealed. A small hole 31 is opened on the slide tube 29. A return spring 30 is sleeved on the outer wall of the slide tube 29.

[0021] A pull-down member 25 is fixedly connected to the outer wall of the slide tube 29. The pull-down member 25 is slidably connected to the transfer cavity 21. A torsion spring shaft 26 is provided at the end of the pull-down member 25. A pressure plate 27 is fixedly connected to the torsion spring shaft 26. A blocking member 28 is fixedly connected to the outer wall of the pull-down member 25. The blocking member 28 is in contact with the pressure plate 27. A first start-stop switch 22 is fixedly connected to the outer wall of the suction member 11. The first start-stop switch 22 is located on the side of the support frame 18.

[0022] In this embodiment, this equipment is a type of automatic metal welding equipment manufactured in the intelligent manufacturing equipment industry. During operation, the main beam of the high-speed engineering vehicle chassis is placed on the main beam placement platform 4. Multiple sets of lateral hydraulic telescopic rods 3 push the workpiece to complete the assembly. When performing the outer wrapping of the main beam and the straight butt joint section of the subframe main beam, in this welding condition where welding is performed continuously from the start of the weld to the end without interruption, the operator relies on the built-in drive system of the drive component 6 to control its left and right sliding along the transverse support 5. When the drive component 6 moves the welding torch 7, it moves synchronously through the side support 8 and the suction pipe 9. The suction pipe 9 is connected to a dust collection device to create negative pressure in the suction component 11. During the movement of the suction component 11, the hard scraper 14 first scrapes away the loose rust, dust and other weakly adhering impurities in the area to be welded, and then the cleaning brush 15 cleans the remaining debris a second time. The debris generated during the cleaning is then absorbed by the suction component 11 and transported to the external suction device through the flow pipe 20. After the dust removal equipment is cleaned, the drive unit 6 continues to move forward. The detection sensor 32, together with the monitoring head 44, collects the bonding gap data of the plates to be welded to determine the tightness of the splicing. Cleaning the detection area in advance can eliminate the problem of debris blocking the lens, ensuring that the spacing detection data of the detection sensor 32 is accurate and reliable. When the monitoring head 44 is working, the side nozzle 36 connected to the suction unit 11 continuously sucks the dust-laden airflow around the monitoring head 44 to avoid dust adhering and contaminating the lens, ensuring detection accuracy. When the detection sensor 32 passes the test, the welding torch 7 starts welding. The side cooling unit 10 connected to the suction pipe 9 generates airflow simultaneously to carry away the working heat of the welding torch 7, avoiding high temperature loss of the welding torch 7. The whole process integrates cleaning, dust removal, gap detection, lens protection, welding torch 7 cooling, and welding. The process is linked and continuous, effectively reducing weld porosity and incomplete fusion defects, and simultaneously extending the service life of the welding torch 7 and the detection element.

[0023] During the cleaning process, the hard scraper 14 is prone to encountering hard impurities such as sintered welding slag from the frame plates, thick layers of oxide rust, and hard stamping iron filings. These impurities are too hard to scrape off. When the hard scraper 14 encounters hard impurities during cleaning, it will hinder the movement of the hard scraper 14, while the drive component 6 will still drive the suction component 11 to slide forward. In this state, the suction component 11 will drive the pull-down component 25 to overcome the elastic force of the pressing spring 17 and move towards the cleaning component 13. During this process, the pressure plate 27 will move along the wedge-shaped component 23 at an angle. As the surface slides against the surface, the left side of the pressure plate 27 is limited by the blocking part 28, and the wedge-shaped part 23 overcomes the elastic force of the return spring 30 and presses down on the pull-down part 25 through the pressure plate 27. The pull-down part 25 simultaneously drives the slide tube 29 to move down, allowing the small hole 31 to enter the first marking tube 19. As the suction part 11 continues to move, the pressure plate 27 will disengage from the wedge-shaped part 23 under its action. At this time, under the elastic force of the return spring 30, the pull-down part 25 and the slide tube 29 will reset, allowing the small hole 31 to return to its original position. After the first marking tube 19 is removed from the outside, the small hole 31 extends into the first marking tube 19. The marking pigment sent from the marking box 40 to the transfer chamber 21 through the flow pipe 20 will flow into the slide tube 29 through the upper opening end of the slide tube 29, and finally drip a small amount into the first marking tube 19 through the small hole 31. Then, it drips through the first marking tube 19 to the area to be welded where hard impurities are blocked. In the later stages of the operation, maintenance personnel can quickly locate the fault point based on the pigment marks. The suction component 11 moves closer to the cleaning component 13. When the support frame 18 presses the first start / stop switch 22, the welding gun 7 immediately cuts off the welding output. The drive component 6, carrying the suction component 11, retracts to the leftmost end of the transverse support 5 to wait for manual cleaning of impurities. During this process, the hard scraper 14 loses its obstruction and resets under the elastic force of the pressing spring 17. The cleaning component 13, along with the support frame 18, returns to its position. The back side plane of the wedge-shaped component 23 adheres to the pressure plate 27 and pushes the pressure plate 27 to flip to the right along the torsion spring shaft 26. The pull-down component 25 is no longer pressed down, and the marking pipeline stops discharging material.

[0024] Example 2: Please refer to Figure 1 - Figure 11 The detection mechanism includes a detection sensor 32 fixedly connected to the suction component 11. A shield 33 and a monitoring head 44 are installed on the detection sensor 32. A spray cylinder 35 is fixedly connected to the outer wall of the suction component 11. An atomizing nozzle 34 is connected to the end of the spray cylinder 35. A push rod 47 is slidably connected through the inside of the spray cylinder 35. A bidirectional telescopic rod 39 is fixedly connected to the outer wall of the suction component 11. The left side of the bidirectional telescopic rod 39 is fixedly connected to the push rod 47. A suction pipe 46 is provided through the spray cylinder 35. The other end of the suction pipe 46 is connected to the inside of the side storage box 45.

[0025] A second marking tube 24 is connected to the transfer cavity 21, and a square box 37 is connected to the second marking tube 24. A sliding plate 38 is slidably connected through the inside of the square box 37. The end of the sliding plate 38 is connected to the right side of the bidirectional telescopic rod 39. A second start / stop switch 41 is fixedly connected to the right side of the bidirectional telescopic rod 39.

[0026] The suction component 11 is internally connected to a side nozzle 36 and a side cooling component 10. The side nozzle 36 is internally rotatably connected to a baffle plate 12. A gear 43 is fixedly connected to the end of the baffle plate 12. A rack 42 is fixedly connected to the outer wall of the push rod 47. The rack 42 and the gear 43 are meshed.

[0027] Both sides of the main body 1 of the equipment are fixedly connected to side plates 2, and multiple hydraulic telescopic rods 3 are fixedly connected to the side plates 2.

[0028] In this embodiment, referring to the above principle, if the detection sensor 32 determines through the monitoring head 44 that the gap between the two workpieces to be welded is too large and does not meet the welding process standard, the detection sensor 32 controls the right end of the bidirectional telescopic rod 39 to first retract and then quickly extend. The bidirectional telescopic rod 39 will pull the moving plate 38 to move to the left briefly and then reset. During the leftward movement of the moving plate 38, the complete blockage of the opposite box 37 is released. The marking pigment is sent into the transfer chamber 21 through the flow pipe 20 and guided to the upper end of the second marking tube 24. It can then flow down briefly to the bottom of the second marking tube 24 through the gap left by the moving plate 38 and finally drip onto the welding area where the gap exceeds the standard. When the moving plate 38 moves to the left, it will press the second start / stop switch 41, and the welding gun 7 will immediately stop the welding operation. The driving component 6 drives the suction component 11 to retract to the leftmost end of the horizontal moving bracket 5. The operator can use this mark to trim the workpiece.

[0029] If the detection sensor 32 identifies, through the monitoring head 44, that the weld gap of the workpiece is too large but still meets the welding conditions, the detection sensor 32 drives the left end of the bidirectional telescopic rod 39 to quickly extend and retract to reset, thereby pushing the push rod 47 to slide back and forth inside the spray nozzle 35. The reciprocating movement of the push rod 47 can evenly atomize and spray the flux pre-stored in the spray nozzle 35 onto the weld position with the large gap through the atomizing nozzle 34. The atomized flux can remove the oxide layer on the surface of the plate, improve the fusion effect of the molten pool, and reduce the probability of porosity and non-fusion defects. No machine stoppage or rework is required, which effectively improves the continuity of processing and the yield of finished products. After the atomizing nozzle 34 completes the spraying operation, the subsequent welding gun 7 will increase the wire feed to weld the gap area.

[0030] It should be noted that after the push rod 47 moves to atomize and spray flux from the spray nozzle 35, when the left end of the bidirectional telescopic rod 39 retracts and resets, the suction pipe 46 simultaneously draws the flux stored inside the side storage box 45 to replenish the inside of the spray nozzle 35, reserving material for the next round of spraying. Both the suction pipe 46 and the atomizing nozzle 34 have built-in one-way valves. The one-way valves limit the suction pipe 46 to only have the function of drawing and replenishing the flux, and the atomizing nozzle 34 to only spray the flux outward, preventing the flux from flowing back into the pipeline and ensuring a stable and orderly cycle of replenishment and spraying processes. The marking pigment is a water-soluble water-based dye preparation, which does not contain impurities such as grease and refractory resin. It can be quickly wiped away with just water and a lint-free cloth, leaving no solid residue on the surface of the base material. It will not change the performance of the welding interface of the plate and will not interfere with the subsequent arc fusion.

[0031] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
