Description

Technical Field

[0001] The invention relates to the technical field of vehicle frame welding, in particular to a multi-station welding device for manufacturing a vehicle frame. Background Art

[0002] When assembling parts such as motorcycles and automobile frames, it is necessary to splice the steel pipes that make up the frame into corresponding shapes, and use existing welding methods to connect and fix the joints of the steel pipes. Metal welding is a forming method that uses heating or pressurization, or both, to create an atomic bond between two separate objects and connect them into one. Material processing for welding production, including steel pretreatment, refers to the preparation and processing before assembly welding, which refers to a series of processing of metal rolled products, the basic material of most welding structures.

[0003] According to the publication number "CN219113214U", a multi-station welding device for frame manufacturing includes two groups of connecting rods and two groups of support plates movably installed at the ends of the two groups of connecting rods. The support plates are evenly provided with fixing holes, and fixing rods, etc. are detachably installed in the fixing holes.

[0004] Although the prior art solves the problem of removing the welded frame and then replacing the new frame steel pipe, which leads to a waste of time, when welding parts, the parts need to be turned over for welding on both sides. At the same time, the welding slag is scattered on the ground and cannot be cleaned up, resulting in poor welding efficiency. Summary of the invention

[0005] The purpose of the present invention is to solve the following shortcomings in the prior art: when welding parts, the parts need to be turned over for welding on both sides, and the welding slag is scattered on the ground and cannot be cleaned up, resulting in poor welding efficiency. A multi-station welding equipment for frame manufacturing is proposed.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] A multi-station welding device for manufacturing a vehicle frame, comprising a base and a vertical tube, wherein a plurality of the vertical tubes are respectively fixedly connected to the four corners of the base;

[0008] The base is provided with a placement slot, the base is provided with a groove, the groove is arranged on one side of the placement slot, a flip component is installed on the base, the flip component includes a flip plate, a rotating shaft, a gear, and a rack plate, the rotating shaft is rotatably connected to the base, one end of the flip plate is fixedly connected to the rotating shaft, the flip plate is arranged in the groove, the two gears are respectively fixedly connected to the two ends of the rotating shaft, the two rack plates are respectively slidably connected to the two sides of the base, and the rack plate is meshed with the gear;

[0009] A fixing component is installed on the base, and the fixing component includes a sleeve, a piston, and a connecting pipe. The sleeve is rotatably connected to the fixing rod, and the sleeve is elliptical. The two pistons are respectively slidably connected to the two ends of the sleeve, and the connecting pipe is fixedly connected between the sleeve and the two vertical cylinders.

[0010] Preferably, the flip component further comprises a fixing rod, the fixing rod is fixedly connected between the two rack plates, both ends of the fixing rod are respectively provided with threads, and the two pistons are respectively threadedly connected to both ends of the fixing rod.

[0011] Preferably, the fixing component further comprises a suction cup, and a plurality of the suction cups are respectively fixedly connected to the lower end of the vertical cylinder.

[0012] Preferably, a gas collecting chamber is fixedly connected to the base, the gas collecting chamber is arranged at one side of the placement groove, and an exhaust port arranged in an inclined manner is opened on the side wall of the gas collecting chamber.

[0013] Preferably, a protrusion is fixedly connected to one of the rack plates, and an airbag is fixedly connected to the protrusion.

[0014] Preferably, a fixing block is fixedly connected to the base, the fixing block is fixedly connected to one end of the airbag away from the protrusion, and an air delivery pipe is fixedly connected between the airbag and the air collecting cavity.

[0015] Preferably, the flip plate is provided with two elliptical grooves, and sliding rods are slidably connected in the two elliptical grooves respectively.

[0016] Preferably, the two sliding rods are respectively fixedly connected with a collar, the collar is arranged in a square shape and slides on the flip plate, and a hydraulic rod is fixedly connected between the two collars.

[0017] Preferably, one side of the two collars is respectively fixedly connected with a clamping plate.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. Place the frame to be welded on the clamping plate at the bottom, then drive the hydraulic rod to retract, and pull the clamping plates fixed on both sides to move to the center to quickly clamp and fix the frame.

[0020] 2. Since the suction cup is located at the lower end of the vertical cylinder and is connected to the vertical cylinder, when there is a negative pressure in the sleeve, the gas in the vertical cylinder can be absorbed through the connecting pipe. At this time, the two suction cups on the right side can only be adsorbed on the ground to fix the base, avoiding the base from shifting when welding the frame on the base, causing unstable welding, and resulting in low welding efficiency.

[0021] 3. As the rack plate moves to the left, the gear and the shaft can be driven to rotate clockwise. At this time, the flip plate can rotate with the shaft and is at the right end of the base, which can realize multi-station welding and facilitate welding on the other side of the frame. It can achieve the effect of fast welding on both sides without unfastening the frame during welding, thereby improving welding efficiency.

[0022] 4. When the rack plate moves to the right, the rack plate can squeeze the airbag through the convex block. After the airbag is squeezed, the internal gas is transmitted to the gas collecting chamber through the gas pipe, and is discharged into the placement groove through the exhaust port on the side wall of the gas collecting chamber. Since the exhaust port is inclined, the exhausted gas can blow the welding slag in the placement groove to the left, so as to clean the welding slag on the base. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0029] Reference Figure 1-Figure 4 A multi-station welding device for frame manufacturing includes a base 1 and a vertical tube 2. A plurality of vertical tubes 2 are respectively fixedly connected to the four corners of the base 1, and the plurality of vertical tubes 2 can support the base 1.

[0030] A placement groove is provided on the base 1, a groove 10 is provided on the base 1, and the groove 10 is arranged on one side of the placement groove. A flip component is installed on the base 1, and the flip component includes a flip plate 15, a rotating shaft 18, a gear 4, and a rack plate 3. The rotating shaft 18 is rotatably connected to the base 1, and one end of the flip plate 15 is fixedly connected to the rotating shaft 18. The flip plate 15 is arranged in the groove 10. Therefore, when the flip plate 15 is horizontally arranged, one side of the flip plate 15 is in the groove 10, so that the frame between the two clamping plates 17 is in the placement groove, and the horizontal arrangement is convenient for welding. The two gears 4 are respectively fixedly connected to both ends of the rotating shaft 18, and the two rack plates 3 are respectively slidably connected. Connected to both sides of the base 1, the rack plate 3 is meshed with the gear 4, and the movement of the rack plate 3 can drive the gear 4 and the rotating shaft 18 to rotate. The flip component also includes a fixed rod 12, and the fixed rod 12 is fixedly connected between the two rack plates 3. The fixed rod 12 is used to fix the two rack plates 3 so that the two rack plates 3 can move synchronously. Threads are respectively provided at both ends of the fixed rod 12, and two pistons 19 are respectively threadedly connected to the two ends of the fixed rod 12. The threads on the fixed rod 12 are set in the sleeve 11, and the two ends of the sleeve 11 are in contact with the fixed rod 12. The outer surface of the fixed rod 12 is smoothly set, so that the sleeve 11 can stably rotate on the fixed rod 12.

[0031] A fixed component is installed on the base 1, and the fixed component includes a sleeve 11, a piston 19, and a connecting pipe 9. The sleeve 11 is rotatably connected to the fixed rod 12. The sleeve 11 is set in an elliptical shape. The two pistons 19 are respectively slidably connected to the two ends of the sleeve 11. The sleeve 11 and the piston 19 are both set in an elliptical shape. Therefore, when the sleeve 11 rotates, the two pistons 19 can be driven to rotate on the fixed rod 12. As the pistons 19 move away from each other, negative pressure is formed between the two pistons 19 in the sleeve 11. The two ends of the sleeve 11 are not in a closed state. The connecting pipe 9 is fixed. It is connected between the sleeve 11 and the two vertical tubes 2. The connecting tube 9 is made of rubber material. When the rack plate 3 and the sleeve 11 move to the right, it will not affect the fixation of the airbag 6. The fixing component also includes a suction cup 23. A plurality of suction cups 23 are respectively fixed and connected to the lower ends of the vertical tubes 2. The suction cups 23 are in contact with the smooth ground. Therefore, when negative pressure is formed in the suction cups 23, the suction cups 23 can be tightly adsorbed on the ground to fix the base 1, thereby avoiding the displacement of the base 1 when welding the frame on the base 1, causing unstable welding, and resulting in low welding efficiency.

[0032] A gas collecting chamber 13 is fixedly connected to the base 1, and the gas collecting chamber 13 is arranged on one side of the placement groove. An exhaust port 22 is arranged obliquely on the side wall of the gas collecting chamber 13, and the opening of the exhaust port 22 is facing the left side of the placement groove. Therefore, the gas discharged from the exhaust port 22 can blow the welding slag in the placement groove from right to left, so as to clean the welding slag on the base 1. A protrusion 5 is fixedly connected to one of the rack plates 3, and an air bag 6 is fixedly connected to the protrusion 5. A fixed block 7 is fixedly connected to the base 1, and the fixed block 7 is fixedly connected to the end of the air bag 6 away from the protrusion 5. An air supply pipe 8 is fixedly connected between the air bag 6 and the gas collecting chamber 13.

[0033] Two elliptical grooves 21 are provided on the flip plate 15, and slide bars 20 are slidably connected in the two elliptical grooves 21 respectively. Rings 16 are fixedly connected to the two slide bars 20 respectively. The rings 16 are arranged in a square shape and slide on the flip plate 15. A hydraulic rod 14 is fixedly connected between the two rings 16. Clamps 17 are fixedly connected to one side of the two rings 16 respectively. The hydraulic rod 14 is driven to contract and pull the clamps 17 fixedly connected on both sides to move centrally and form a quick clamping and fixing of the frame. At the same time, when the hydraulic rod 14 is extended, the hydraulic rod 14 can push the two clamps 17 away from each other and no longer clamp the frame, so that the welded frame can be taken out easily.

[0034] In the present invention, when in use, the frame to be welded is first placed on the clamping plate 17 located at the lower side, and then the hydraulic rod 14 is driven to contract and pull the clamping plates 17 fixedly connected on both sides to move centrally and form a quick clamping and fixing of the frame.

[0035] Then, the sleeve 11 is rotated. Since the sleeve 11 and the piston 19 are both elliptical in shape, the two pistons 19 can be driven to rotate when the sleeve 11 rotates. Since the pistons 19 are respectively threadedly connected to the two ends of the fixing rod 12, the two pistons 19 can move away from each other when rotating, so that negative pressure is present between the two pistons 19 in the sleeve 11. Since the suction cup 23 is located at the lower end of the vertical cylinder 2 and is connected to the vertical cylinder 2, when negative pressure is present in the sleeve 11, the gas in the vertical cylinder 2 can be adsorbed through the connecting pipe 9. At this time, the two suction cups 23 on the right side can only be adsorbed on the ground to fix the base 1, thereby avoiding the base 1 from shifting when welding the frame on the base 1, resulting in unstable welding and low welding efficiency.

[0036] After the base 1 is fixed, when it is necessary to fix the frame between the two clamping plates 17, first pull the two rack plates 3 to the right. As the rack plates 3 move to the right, the gear 4 and the rotating shaft 18 can be driven to rotate counterclockwise, and the flip plate 15 can be driven to flip to the left to a horizontal state along with the rotating shaft 18. At this time, the frame is at the left end of the base 1 and is arranged horizontally, which is convenient for welding one side of the frame. When it is necessary to weld the other side of the frame, the rack plate 3 is pushed to the left. As the rack plate 3 moves to the left, the gear 4 and the rotating shaft 18 can be driven to rotate clockwise. At this time, the flip plate 15 can rotate 180 degrees along with the rotating shaft 18 and is at the right end of the base 1, so as to facilitate welding on the other side of the frame, so that the frame can be welded quickly on both sides without unfastening during welding, thereby improving welding efficiency.

[0037] At the same time, when the rack plate 3 moves to the right, the rack plate 3 can squeeze the airbag 6 through the protrusion 5. After the airbag 6 is squeezed, the internal gas is transmitted to the gas collecting chamber 13 through the gas pipe 8, and is discharged into the placement groove through the exhaust port 22 on the side wall of the gas collecting chamber 13. Since the exhaust port 22 is arranged at an angle, the exhausted gas can blow the welding slag in the placement groove to the left, so as to clean the welding slag on the base 1.

[0038] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
