Description

Technical Field

[0001] This application relates to the technical field of automatic welding equipment, and in particular to a multi-station, multi-functional rotary welding machine. Background Technology

[0002] Welding, also known as fusion welding, is a manufacturing process and technology that joins metals or other thermoplastic materials such as plastics by heating, high temperature, or high pressure. Modern welding uses a variety of energy sources, including gas flames, electric arcs, lasers, electron beams, friction, and ultrasound. In addition to its use in factories, welding can also be performed in various environments, such as outdoors, underwater, and in space.

[0003] Most existing multi-station rotary welding machines are designed for single-station welding and single-station loading / unloading, with the remaining stations waiting to be welded or disassembled. This setup results in insufficient utilization of multiple stations. Furthermore, the workpiece is hot after welding, and handling it directly can easily cause burns. Therefore, the workpiece needs to cool down before it can be removed, which takes a long time and results in low welding efficiency. Summary of the Invention

[0004] To improve the welding efficiency of workpieces, this application provides a multi-station, multi-functional rotary welding machine.

[0005] The multi-station, multi-functional rotary welding machine provided in this application adopts the following technical solution: A multi-station, multi-functional rotary welding machine includes a protective shell and a housing. The protective shell is equipped with a touch screen and control buttons. The housing is located on one side of the protective shell and has an open top. A rotating plate is horizontally arranged inside the housing. A rotating assembly that drives the rotating plate to rotate is also located inside the housing. Multiple sets of clamping assemblies are arranged on the upper surface of the rotating plate, and these clamping assemblies are arranged sequentially along the circumference of the rotating plate. Positioning pins for workpiece positioning are provided at the clamping assemblies. A welding torch is connected to the inner wall of one side of the housing, and a cold air nozzle is also connected to the inner wall of one side of the housing. The end of the cold air nozzle faces the upper surface of the rotating plate.

[0006] By adopting the above technical solution, the workpiece is placed on the rotating plate and positioned using positioning pins. The clamping assembly clamps and fixes the workpiece. The rotation speed of the rotating assembly and the dwell time of the workpiece at the welding gun are adjusted using a touch screen. The rotating assembly drives the rotating plate to rotate, the rotating plate drives the clamping assembly to rotate, and the clamping assembly moves the workpiece. When the workpiece rotates to the welding gun, the control button controls the welding gun to start welding the workpiece. After the workpiece is welded, the rotating assembly continues to drive the rotating plate to rotate. When the workpiece rotates to the cold air nozzle, the rotating plate stops rotating, and the cold air nozzle blows cold air onto the workpiece to accelerate the cooling speed. At the same time, the workpiece on the next set of clamping assemblies moves to the welding gun, and the welding gun welds the workpiece. Then the rotating assembly continues to drive the rotating plate to rotate. After the workpiece is cooled, the operator unloads the workpiece and places the unwelded workpiece when the rotation stops for the next time. By setting the cold air nozzle, the cooling speed of the workpiece is accelerated, saving time and thus improving the welding efficiency of the workpiece.

[0007] Optionally, a mounting base is horizontally arranged inside the housing, positioned below the rotating plate. Multiple support rods are fixedly connected to the periphery of the mounting base, with the length direction of the support rods perpendicular to the mounting base. The bottom ends of the support rods are fixedly connected to the bottom wall of the housing. The rotating assembly includes a motor and a rotating shaft. The motor is fixedly connected to the bottom wall of the housing, and the output shaft of the motor is fixedly connected to one end of the rotating shaft. The length direction of the rotating shaft is perpendicular to the mounting base, and the upper end of the rotating shaft passes through the mounting base and the rotating plate, with the rotating shaft and the mounting base being rotatably connected.

[0008] By adopting the above technical solution, the touch screen controls the motor speed, start time, and stop time. When the motor starts, the motor drives the rotating shaft to rotate, and the rotating shaft drives the rotating plate to rotate, thus the rotating component realizes the function of driving the rotating plate to rotate.

[0009] Optionally, the upper surface of the rotating plate is connected to multiple auxiliary plates, and the clamping assembly is set on the auxiliary plates, with each clamping assembly corresponding to one of the auxiliary plates. The clamping assembly includes a first clamping plate and a second clamping plate. A sliding groove is formed on the upper surface of the auxiliary plate, and two sliders are slidably connected to the auxiliary plate in the sliding groove. The first clamping plate and the second clamping plate are respectively fixedly connected to the upper surface of the two sliders. The first clamping plate and the second clamping plate are parallel to each other. A positioning pin is fixedly connected to the upper surface of the auxiliary plate. A first spring is fixedly connected to each of the two sliders on the opposite side. The end of the first spring away from the slider is fixedly connected to the side wall of the sliding groove. The extension and contraction direction of the first spring is parallel to the length direction of the sliding groove.

[0010] By adopting the above technical solution, the first clamping plate and the second clamping plate move in opposite directions, driving the two sliders to move. The first spring is compressed, and the workpiece is placed on the auxiliary plate according to the positioning pin. The workpiece is between the first clamping plate and the second clamping plate. Then the first spring releases its elastic force, pushing the slider to move. The slider drives the first clamping plate or the second clamping plate to move. The first clamping plate and the second clamping plate clamp and fix the workpiece, making it difficult for the workpiece to move freely on the auxiliary plate.

[0011] Optionally, the upper surface of the rotating plate is provided with multiple annular grooves, which are located directly below the auxiliary plate. Multiple support rods are slidably connected in the annular grooves, with the length direction of the support rods perpendicular to the rotating plate and the upper end of the support rods fixedly connected to the auxiliary plate.

[0012] By adopting the above technical solution and setting the support rod, the connection between the auxiliary plate and the rotating plate is realized.

[0013] Optionally, the sliders are arranged with an inclined plane on one side, which is inclined from top to bottom towards the direction of the first spring. A connecting rod is provided on the lower surface of the auxiliary plate. The length direction of the connecting rod is perpendicular to the rotating plate. The upper end of the connecting rod extends through the bottom wall of the slide groove into the slide groove and is located between the two sliders. The connecting rod and the auxiliary plate are slidably connected. The bottom end of the connecting rod extends through the rotating plate and is slidably connected to the rotating plate. The middle part of the connecting rod is cylindrical, and the two opposite ends of the connecting rod are prismatic. A lifting plate is fixedly connected to the inner wall of one side of the housing. The opposite sides of the lifting plate are inclined from top to bottom towards the direction away from each other.

[0014] By adopting the above technical solution, after the workpiece held by the clamping assembly has cooled down, the rotating assembly continues to drive the rotating plate to rotate. The rotating plate drives the connecting rod to move. The bottom end of the connecting rod first abuts against the inclined surface of one side of the lifting plate and pushes the connecting rod upward. The connecting rod moves towards the slide groove. During the movement of the connecting rod, the opposite sides of the upper end of the connecting rod abut against the inclined surfaces of the two sliders respectively and push the sliders to move in opposite directions. The first spring is compressed, and the slider drives the first clamping plate and the second clamping plate to move in opposite directions. The first clamping plate and the second clamping plate release the clamping fixation of the workpiece. The worker removes the workpiece and then places the unwelded workpiece on top. During the continued movement of the connecting rod, the connecting rod disengages from the other inclined surface of the lifting plate and the mold. The first spring releases its elastic force, so that the first clamping plate and the second clamping plate clamp and fix the workpiece. There is no need for the worker to manually move the first clamping plate and the second clamping plate, thus providing convenience for the worker's work.

[0015] Optionally, a limiting groove is formed in the auxiliary plate along the vertical direction, and a limiting block is fixedly connected to the upper side wall of the linkage rod.

A second spring is fixed between the limiting block and the upper side wall of the limiting groove, and the extension and retraction direction of the second spring is parallel to the sliding direction of the linkage rod.

[0016] By adopting the above technical solution, when the connecting rod moves upward, it drives the limiting block to move, and the second spring is compressed. When the connecting rod and the lifting plate are separated, the second spring releases its elastic force, pushing the limiting block to move downward. The limiting block drives the connecting rod to move, and the limiting block abuts against the lower side wall of the limiting groove, making it difficult for the connecting rod to separate from the auxiliary plate.

[0017] Optionally, the welding torch is provided with a flame nozzle on the side away from the cold air nozzle. The flame nozzle is connected to the housing, and the opening end of the flame nozzle is oriented towards the rotating plate.

[0018] By adopting the above technical solution, after the clamping assembly clamps and fixes the workpiece, the rotating plate moves the workpiece first to the flame nozzle, and the flame nozzle preheats the workpiece, which facilitates welding.

[0019] Optionally, a gear is fixedly connected to the bottom end of the linkage rod, and a first rack is fixedly connected to the inner wall of the housing on the side connected to the flame nozzle. The first rack is located below the flame nozzle and is arc-shaped. The gear and the first rack mesh and fit together.

[0020] By adopting the above technical solution, after the workpiece moves to the flame nozzle, the gear and the first rack mesh. During the movement of the rotating plate, the first rack guides the gear to rotate, the gear drives the connecting rod to rotate, the connecting rod drives the auxiliary plate to rotate, and the auxiliary plate drives the workpiece to rotate, so that the workpiece can be heated evenly.

[0021] Optionally, a second rack is fixedly connected to the inner wall of the housing on the side connected to the cold air nozzle. The second rack is located below the cold air nozzle and is in an arc shape. The gear and the second rack mesh and are properly matched.

[0022] By adopting the above technical solution, when the workpiece moves to the cold air nozzle, the gear and the second rack mesh.

[0023] Optionally, the rotating plate has a limiting groove at the connecting rod, and the limiting groove and the prism end of the connecting rod are engaged and adapted. The housing is fixedly connected to push plates directly below the first rack and the second rack, and the opposite sides of the push plates are inclined from top to bottom in a direction away from each other.

[0024] By adopting the above technical solution, when the second spring pushes the limiting block to move downward, it drives the prism end of the connecting rod to move into the limiting groove, so that the auxiliary plate is not easy to rotate during the rotation of the rotating plate. When it moves to the first rack or the second rack, the bottom end of the connecting rod first abuts against the inclined surface of the push plate and pushes the connecting rod to move upward. The prism end of the connecting rod disengages from the limiting groove, and at the same time, the upper end of the connecting rod pushes the slider to move. Then the gear meshes with the first rack or the second rack. The setting of the push plate enables the connecting rod to rotate.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1.

A rotating assembly 3 for driving the rotating plate 21 to rotate is arranged inside the housing 2. The rotating assembly 3 includes a motor 31 and a rotating shaft 32. The motor 31 is fixedly connected to the bottom wall of the housing 2. The output shaft of the motor 31 is fixedly connected to one end of the rotating shaft 32. The length direction of the rotating shaft 32 is perpendicular to the rotating plate 21. The rotating shaft 32 passes through the mounting base and is fixedly connected to the rotating plate 21.

[0033] refer to Figure 1 and Figure 3 The upper surface of the rotating plate 21 is provided with eight auxiliary plates 6, which are arranged sequentially around the periphery of the rotating plate 21. The auxiliary plates 6 are parallel to the rotating plate 21. The upper surface of the rotating plate 21 is provided with eight annular grooves 211, which are located directly below the auxiliary plates 6 and correspond one to one. Multiple support rods 212 are fixedly connected to the lower surface of the auxiliary plates 6. The length direction of the support rods 212 is perpendicular to the auxiliary plates 6, and the lower end of the support rods 212 extends into the annular grooves 211. The support rods 212 and the rotating plate 21 are slidably connected. The upper surface of the auxiliary plate 6 is fixedly connected with a positioning pin 5. The upper surface of the auxiliary plate 6 is provided with a sliding groove 61. Two sliders 62 are slidably connected to the auxiliary plate 6 in the sliding groove 61. The two sliders 62 are fixedly connected to a first spring 63 on one side away from each other. The end of the first spring 63 away from the slider 62 is fixedly connected to the end side wall of the sliding groove 61. The extension and contraction direction of the first spring 63 is parallel to the movement direction of the slider 62. The upper surface of the auxiliary plate 6 is provided with a clamping assembly 4 for clamping and fixing the workpiece.

[0034] The clamping assembly 4 includes a first clamping plate 41 and a second clamping plate 42. The first clamping plate 41 and the second clamping plate 42 are parallel to each other. The first clamping plate 41 and the second clamping plate 42 are respectively fixedly connected to the upper surfaces of the two sliders 62. The first clamping plate 41 is perpendicular to the auxiliary plate 6.

[0035] First, the two sliders 62 move in opposite directions, and the first spring 63 is compressed. The workpiece is placed between the first clamping plate 41 and the second clamping plate 42 according to the positioning pin 5. Then, the first spring 63 releases its elastic force, pushing the two sliders 62 to move in opposite directions. The sliders 62 drive the first clamping plate 41 or the second clamping plate 42 to move. The first clamping plate 41 and the second clamping plate 42 clamp and fix the workpiece, making it difficult for the workpiece to move freely on the auxiliary plate 6.

[0036] refer to Figure 1 , Figure 3 and Figure 4A connecting rod 64 is provided below the auxiliary plate 6. The length direction of the connecting rod 64 is perpendicular to the auxiliary plate 6. The two ends of the connecting rod 64 are prismatic, and the middle part is cylindrical. The upper end of the connecting rod 64 passes through the inner bottom wall of the slide groove 61 and is slidably connected to the auxiliary plate 6. The lower end of the connecting rod 64 passes through the rotating plate 21 and is slidably connected to the rotating plate 21. A limiting groove 68 is provided on the upper surface of the rotating plate 21 at the connection of the connecting rod 64. The limiting groove 68 and the prismatic part at the upper end of the connecting rod 64 are engaged and adapted. An internal limiting groove 65 is provided, which is located below the slide groove 61. The upper end of the connecting rod 64 passes through the limiting groove 65. Limiting blocks 66 are fixedly connected to the opposite sides of the upper end of the connecting rod 64. The end of the limiting block 66 away from the connecting rod 64 extends into the limiting groove 65. A second spring 67 is fixed between the connecting rod 64 and the upper wall of the limiting groove 65. The two sliders 62 are both set as inclined surfaces on the side close to each other. The inclined surfaces are inclined from top to bottom towards the direction of the first spring 63.

[0037] The linkage rod 64 moves upward, and its upper end moves out of the limiting groove 68. The upper end of the linkage rod 64 abuts against the inclined surfaces of the two sliders 62 on both sides, pushing the two sliders 62 to move in opposite directions. This causes the first clamping plate 41 and the second clamping plate 42 to move in opposite directions, which is used to release the clamping and fixing of the workpiece or to place the workpiece. The first spring 63 is compressed, and at the same time, the linkage rod 64 drives the limiting block 66 to move. The second spring 67 is compressed. When the push on the linkage rod 64 is released, the first spring 63 and the second spring 67 both release their elastic force, causing the linkage rod 64 to move downward. This causes the prism at the upper end of the linkage rod 64 to move into the limiting groove 68. The limiting groove 68 restricts the linkage rod 64 from rotating, thus making it difficult for the auxiliary plate 6 to rotate.

[0038] refer to Figure 3 and Figure 5 A lifting plate 25 is fixedly connected to one side wall of the housing 2. The lifting plate 25 is horizontally set, and the opposite sides of the lifting plate 25 are inclined from top to bottom in opposite directions. During the rotation of the connecting rod 64 driven by the rotating plate 21, the connecting rod 64 first abuts against the inclined surface of one side of the lifting plate 25. Under the guidance of the lifting plate 25, the connecting rod 64 moves upward relative to the rotating plate 21, so that the upper end of the connecting rod 64 extends into the slide groove 61 and presses the slider 62 to both sides.

[0039] refer to Figure 1 , Figure 2 and Figure 6Two first connecting rods 7 are fixedly connected to the outer wall of the housing 2.

The push plate 29 is horizontally set, and the opposite sides of the push plate 29 are inclined from top to bottom in a direction away from each other.

[0041] After the workpiece is placed on the auxiliary plate 6, the rotating plate 21 drives the connecting rod 64 to rotate. When the connecting rod 64 rotates to the flame nozzle 26, it first abuts against the inclined surface on one side of the push plate 29 and moves upward a certain distance under the guidance of the push plate 29. Then, the first rack 27 meshes with the gear 641. Under the guidance of the first rack 27, the gear 641 rotates, which drives the connecting rod 64 to rotate. The connecting rod 64 drives the auxiliary plate 6 to rotate the auxiliary plate 21, which in turn drives the workpiece to rotate. The flame nozzle 26 preheats the workpiece. Then the connecting rod... The push rod 64 disengages from the push plate 29 on the other side of the inclined surface and moves to the welding gun 22. The welding gun 22 welds the workpiece. After welding, the rotating plate 21 drives the workpiece to continue rotating and moves to the cooling nozzle. First, the bottom end of the connecting rod 64 abuts against the inclined surface on one side of the push plate 29. Under the guidance of the push plate 29, it moves upward a distance. Then, the gear 641 and the second rack 28 mesh. Under the guidance of the second rack 28, the gear 641 rotates. At the same time, the cooling nozzle 23 cools the workpiece, thereby accelerating the welding and cooling speed of the workpiece.

[0042] The implementation principle of a multi-station multi-functional rotary welding machine according to an embodiment of this application is as follows: The workpiece is placed on the auxiliary plate 6, and the clamping assembly 4 clamps and fixes the workpiece. The rotating assembly 3 drives the rotating plate 21, which in turn drives the auxiliary plate 6 to move. The auxiliary plate 6 then drives the workpiece to move. When the workpiece moves to the flame nozzle 26, the flame nozzle 26 preheats the workpiece to facilitate welding. Then, the workpiece moves to the welding torch 22, where the welding torch 22 welds the workpiece. After welding, the rotating plate 21 continues to rotate the workpiece, which then moves to the cooling nozzle 23. The cooling nozzle 23 cools the workpiece, allowing it to cool down quickly and saving cooling time, thereby improving the welding efficiency of the workpiece.
