Description

Technical Field

[0001] The invention relates to the technical field of automobile parts processing, in particular to an automobile water pipeline butt welding device. Background Art

[0002] As we all know, automobile water pipes are piping equipment used to guide and transport cooling water inside the car. They enable water to flow through the engine and radiator, making it convenient for the water to carry the heat in the engine to the radiator and dissipate heat, ensuring that the engine can continue to work at normal temperature.

[0003] When processing water pipes, in order to ensure that the pipes have good fluidity, they are generally bent by butt welding rather than by direct bending. When the water pipes are butt-jointed, the butt joint is an inclined surface, so the butt joint track is an ellipse. Traditional welding equipment cannot weld the weld of the track shape and can only rely on manual welding. Manual welding has low work efficiency, consumes a lot of manpower, and has poor uniformity of the weld, which easily affects the welding strength. Summary of the invention

DETAILED DESCRIPTION

[0023] 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.

[0024] In the description of the present invention, it should be noted that the orientations or positional relationships indicated by “center”, “up”, “down”, “left”, “right”, “vertical”, “horizontal”, “inside” and “outside”, etc., are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0025] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. This embodiment is written in a progressive manner.

[0026] like Figure 1 to Figure 2 As shown, an automobile water pipeline butt welding device of the present invention comprises two fixed cylinders 1, the axes of the two fixed cylinders 1 are in an angle state, a water pipe 2 is arranged in the fixed cylinder 1, the outer end cutouts of the two water pipes 2 are butt-jointed, a rotating cylinder 3 is rotatably sleeved on the outer wall of the fixed cylinder 1, two sliding rods 4 are arranged on the rotating cylinder 3, the sliding rods 4 pass through the rotating cylinder 3 and are slidably connected to each other, the length direction of the sliding rod 4 is parallel to the axis direction of the fixed cylinder 1, a rotating ball 5 is arranged at the end of the sliding rod 4, a center plate 6 is arranged between the two fixed cylinders 1, the rotating ball 5 is rotatably embedded in the center plate 6, a welding gun 7 is arranged on the center plate 6, and the direction of the welding gun 7 is perpendicular to the line connecting the center points of the two fixed cylinders 1.

[0027] Specifically, the water pipe 2 is fixed in the fixed cylinder 1, the axis of the water pipe 2 coincides with the axis of the fixed cylinder 1, the fixed cylinder 1 is in a fixed state, and the two rotating cylinders 3 rotate synchronously, and the rotation directions of the two rotating cylinders 3 are opposite. The rotating cylinder 3 drives the center plate 6 to move synchronously through the two sliding rods 4 and the two rotating balls 5 thereon. Since the two rotating cylinders 3 synchronously drive the center plate 6 to move, the center plate 6 moves in a circular shape along the vertical plane where the two water pipes 2 are connected. The two sliding rods 4 are parallel to the water pipes 2, so that the center plate 6 moves in an elliptical circular shape around the two water pipes 2 docking positions. The distance between the center plate 6 and the docking position is always maintained within a specified range. The center plate 6 drives the welding gun 7 to move synchronously, so that the welding gun 7 performs an elliptical welding process on the docking position. Since the distance between the welding gun 7 and the docking position is always maintained within a specified range, the uniformity of welding is improved to avoid inconsistent melting degrees of the welding gun 7 on the docking position when the distance changes greatly, resulting in uneven welds.

[0028] By controlling the welding gun 7 to move elliptically around the docking position of the two water pipes 2 and perform welding work, the automatic welding processing method of the bent pipe can be realized, which effectively improves the work efficiency and liberates manpower. At the same time, since the distance between the welding gun 7 and the weld is always maintained within the specified range, the welding uniformity is effectively improved and the welding quality is improved.

[0029] like Figures 1 to 4As shown, as a preferred embodiment of the above embodiment, it also includes a base plate 8, a tooth row 9 is slidably arranged on the base plate 8, the sliding trajectory of the tooth row 9 is arc-shaped, the teeth on the tooth row 9 are bevel teeth, and a first transmission ring 10 is rotatably mounted on the outer wall of the rotating drum 3. The end face of the first transmission ring 10 is provided with helical teeth, and the circumferential outer wall of the first transmission ring 10 is provided with bevel teeth. The bevel teeth on the first transmission ring 10 are meshed with the tooth row 9, and the helical teeth on the first transmission ring 10 are meshed with two helical gears 11. The two helical gears 11 are rotatably installed on the outer wall of the rotating drum 3, and the side wall of the sliding rod 4 is provided with helical teeth. The helical teeth on the sliding rod 4 are meshed with the helical teeth on the helical gear 11.

[0030] Specifically, when the rotating drum 3 pushes the center plate 6 to move in an elliptical shape, the center plate 6 pulls the slide bar 4 in the opposite direction to slide on the rotating drum 3, and the bevel teeth on the slide bar 4 drive the bevel gear 11 to rotate, and the bevel gear 11 drives the first transmission ring 10 to rotate, and the first transmission ring 10 drives the gear row 9 to rotate. Since the two first transmission rings 10 are both meshed and connected with the gear row 9, the two first transmission rings 10 can synchronously push the gear row 9 to move, so that the two first transmission rings 10 maintain a synchronous rotation state, which is convenient for keeping the slide bars 4 on the two rotating drums 3 in a synchronous movement state, and conveniently positioning the direction of the center plate 6, avoiding the center plate 6 from tilting and swinging on the four rotating balls 5 and causing the muzzle of the welding gun 7 to be unable to face the direction of the weld, ensuring that the welding gun 7 can move smoothly and perform stable welding processing on the weld.

[0031] As the drum 3 moves in a circular motion, the slide bar 4 moves back and forth on the drum 3 , thereby causing the tooth row 9 to slide back and forth on the bottom plate 8 .

[0032] like Figures 1 to 4 As shown, as a preferred embodiment of the above embodiment, a right-angle plate 12 is fixed on the outer wall of the fixed cylinder 1, and the right-angle plate 12 is located on the outer sides of the two fixed cylinders 1. An arc guide rail 13 is fixed on the bottom plate 8, and the bottom of the right-angle plate 12 is slidably mounted on the arc guide rail 13;

[0033] The center of the arc guide rail 13 coincides with the center point of the butt joint of the two water pipes 2 .

[0034] Specifically, by arranging the right-angle plate 12 on the outside of the two fixed cylinders 1, it is convenient to ensure that when the slide rod 4 slides on the rotating cylinder 3, the tail end of the slide rod 4 always remains separated from the right-angle plate 12, thereby preventing the tail end of the slide rod 4 from colliding with the right-angle plate 12 when the slide rod 4 rotates with the rotating cylinder 3 and slides on the rotating cylinder 3.

[0035] The right-angle plate 12 is pushed to slide on the arc guide rail 13 to adjust the inclination angle between the two fixed cylinders 1. Since the center of the arc guide rail 13 coincides with the center point of the docking position of the two water pipes 2, the axis of the fixed cylinder 1 can be conveniently made to always coincide with the center point of the docking position of the two water pipes 2, thereby facilitating the butt welding of two water pipes 2 at any angle, effectively improving the processing range of the equipment.

[0036] like Figure 1 As shown, as a preferred embodiment of the above embodiment, a first motor 14 is fixed on the base plate 8, and a lead screw 15 is provided at the output end of the first motor 14. A threaded sleeve 16 is threadedly mounted on both sides of the lead screw 15, and the left and right sides of the lead screw 15 have opposite threads. The bottom of the threaded sleeve 16 is slidably mounted on the base plate 8, and a push-pull plate 17 is rotatably provided on the outer wall of the threaded sleeve 16, and the outer end of the push-pull plate 17 is rotatably mounted on the outer wall of the right-angle plate 12.

[0037] Specifically, the first motor 14 drives the lead screw 15 to rotate. Since the threads on the left and right sides of the outer wall of the lead screw 15 have opposite rotation directions, the lead screw 15 pushes the two threaded sleeves 16 to rotate synchronously in opposite directions. The two threaded sleeves 16 pull the two right-angle plates 12 to rotate synchronously in opposite directions through the two push-pull plates 17, which makes it convenient to adjust the positions of the two right-angle plates 12 at the same time, and at the same time makes it convenient to keep the center plane of the angle between the two fixed cylinders 1 fixed.

[0038] like Figure 3 As shown, as a preferred embodiment of the above embodiment, a right-angle positioning plate 18 is provided at the bottom of the base plate 8, the top of the right-angle positioning plate 18 passes through the base plate 8 and is slidably connected, the outer wall of the right-angle positioning plate 18 is coplanar with the vertical plane where the two water pipes 2 are connected, and a first cylinder 19 is provided on the right-angle positioning plate 18, and the fixed end of the first cylinder 19 is installed on the base plate 8.

[0039] Specifically, when it is necessary to install the water pipe 2, the first cylinder 19 pushes the right-angle positioning plate 18 upward to the specified position, and a water pipe 2 is passed through the fixed tube 1. The cut position of the water pipe 2 contacts the outer wall of the right-angle positioning plate 18, and then the water pipe 2 is fixed in the fixed tube 1. The first cylinder 19 pushes the right-angle positioning plate 18 to move downward and disengage from the water pipe 2, and then another water pipe 2 is passed through another fixed tube 1 and the cut positions of the two water pipes 2 are docked, thereby completing the docking of the two water pipes 2. By setting the right-angle positioning plate 18, the two water pipes 2 can be quickly positioned conveniently, avoiding the phenomenon that the docking position is easily offset and the cuts on the two water pipes 2 are easily slightly misaligned when the two water pipes 2 are directly docked, effectively improving the docking accuracy of the two water pipes 2 and improving the quality of the bending pipe processing.

[0040] like Figure 5As shown, as a preferred embodiment of the above embodiment, a plurality of clamps 20 are arranged in the fixed cylinder 1, and the plurality of clamps 20 are distributed in a ring shape. Two guide plates 21 are obliquely arranged on the outer wall of the clamp 20, and the two guide plates 21 are parallel. The outer ends of the guide plates 21 are rotatably mounted on the inner wall of the fixed cylinder 1.

[0041] Specifically, multiple clamps 20 are pushed to move synchronously toward the outer wall of the water pipe 2 and squeeze the water pipe 2 to fix it. By setting two guide plates 21 on the clamps 20, the clamps 20 can be conveniently guided so that the direction of the clamps 20 is always toward the axis direction of the fixed tube 1, thereby improving the clamping stability. In addition, the synchronous movement of multiple clamps 20 can realize the positioning of the axis of the water pipe 2 and ensure that the axis of the fixed tube 1 is coaxial with the axis of the water pipe 2.

[0042] like Figure 5 As shown, as a preferred embodiment of the above embodiment, a movable ring 22 is provided on the inner wall of the fixed cylinder 1, and a plurality of adjustment plates 23 are rotatably and obliquely provided on one side wall of the movable ring 22, and the outer end of the adjustment plate 23 is rotatably mounted on the side wall of a guide plate 21 on the clamping plate 20, and a second cylinder 24 is fixed on the other side wall of the movable ring 22, and the fixed end of the second cylinder 24 is mounted on the inner wall of the fixed cylinder 1, and a plurality of guide edges 25 are provided on the inner wall of the fixed cylinder 1, and the movable ring 22 slides on the guide edges 25.

[0043] Specifically, the second cylinder 24 pushes the moving ring 22 to move, and the moving ring 22 slides on the guide ribs 25 . The moving ring 22 pushes the guide plates 21 on the multiple clamping plates 20 to move through the multiple adjustment plates 23 , thereby driving the multiple clamping plates 20 to move synchronously.

[0044] like Figure 1 As shown, as a preferred embodiment of the above embodiment, a second motor 26 is fixed on the side wall of the right-angle plate 12, a transmission wheel 27 is provided at the output end of the second motor 26, a second transmission ring 28 is provided on the transmission wheel 27, and the second transmission ring 28 is fixedly mounted on the outer wall of the rotating drum 3.

[0045] Specifically, the second motor 26 drives the rotating drum 3 to rotate through the transmission wheel 27 and the second transmission ring 28, thereby driving the equipment to operate.

[0046] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
