Description

Technical Field

[0001] This utility model relates to the field of welding positioner technology, and in particular to a welding fixture positioner. Background Technology

[0002] A welding positioner is a specialized auxiliary device used in the welding process. Its main function is to change the posture or position of the workpiece through its own rotation, tilting, or combined movements, so that welders or welding robots can perform welding at the optimal welding angle and posture. It can adjust complex weld joints to a flat welding position, thereby significantly improving welding quality, production efficiency, and reducing the labor intensity of welders. This equipment typically has a high-precision control system and sufficient load-bearing capacity, and is widely used in manufacturing fields requiring high-quality and high-efficiency welding, such as shipbuilding, pressure vessels, engineering machinery, pipelines, and steel structures. It is one of the indispensable key pieces of equipment in modern automated welding production lines.

[0003] In traditional welding fixture positioner applications, slag and spatter generated during welding adhere to the fixture surface. If not cleaned promptly, this not only contaminates the fixture's working area but also reduces the clamping and positioning accuracy of the next workpiece due to residue accumulation, affecting welding quality. Existing cleaning methods mainly rely on manual sweeping, which is not only inefficient and unable to thoroughly remove stubborn residues, but also poses safety risks due to manual operation. Overall, it fails to meet the cleaning efficiency and precision requirements of automated production. Utility Model Content

[0004] One objective of this invention is to provide a positioner for a welding fixture. This invention addresses the problem mentioned in the background that existing cleaning methods mainly rely on manual cleaning, which is not only inefficient and difficult to completely remove stubborn residues, but also poses safety risks due to manual operation. Overall, it is difficult to meet the requirements of automated production for cleaning efficiency and precision.

[0005] A positioner for a welding fixture according to an embodiment of the present invention includes a driving mechanism, a triggering mechanism, and a cleaning mechanism. The driving mechanism includes a driving housing, a fixed housing, and a fixture system. The fixture system is rotatably connected to the inner side of the driving housing via a driven gear. A driving gear is meshed with the lower part of the driven gear. The triggering mechanism includes a rotating rod and a push switch. The push switch is installed inside the driving housing. A turntable is fixedly connected to one side of the driven gear. The rotating rod is fixedly connected to the side surface of the turntable. The cleaning mechanism includes a high-pressure blower. A fixed plate is fixedly connected to the lower inner side of the driving housing. A sliding block is slidably connected to the upper surface of the fixed plate. The high-pressure blower is fixedly connected to the upper surface of the sliding block.

[0006] Preferably, a rotating seat is fixedly connected to the upper surface of the fixed housing, and the clamping system is rotatably connected between the rotating seat and the driven gear via a rotating shaft.

[0007] Preferably, a first drive motor is fixedly connected to the inner side of the drive housing, and the drive gear is connected to the output end of the first drive motor.

[0008] Preferably, a second drive motor is fixedly connected to the lower inner side of the drive housing, and a sliding groove is provided in the middle of the surface of the fixed plate.

[0009] Preferably, the output end of the second drive motor is connected to a screw, the screw is rotatably connected inside the sliding groove, and the sliding block is threadedly connected to the surface of the screw.

[0010] Preferably, a limiting groove is formed through both sides of the surface of the fixing plate, and a limiting rod is fixedly connected inside the limiting groove.

[0011] Preferably, a limiting block is slidably connected to the surface of the limiting rod, and the limiting block is fixedly connected to the lower surface of the high-pressure blower.

[0012] Preferably, a filter screen is fixedly installed at the air outlet on the upper surface of the high-pressure blower.

[0013] The beneficial effects of this utility model are:

[0014] This utility model, through its cleaning mechanism, uses a first drive motor to rotate the driving gear, which in turn rotates the driven gear, ultimately causing the fixture system to rotate 180 degrees so that the welding surface faces downwards. A second drive motor then rotates the screw, causing the sliding block to slide in the sliding groove towards the other side. This allows a high-pressure blower fixedly mounted on the upper surface of the sliding block to blow high-pressure air upwards. The high-pressure air cleans different positions on the welding surface, significantly improving the cleaning efficiency and clamping accuracy of the welding fixture.

[0015] This utility model, through a triggering mechanism, enables the first drive motor to drive the driven gear to rotate via the active gear. As the clamping system flips downwards, the driven gear drives the turntable to rotate, causing the rotating rod to rotate downwards. Once the rotating rod rotates downwards, it triggers a press switch. The press switch controls the drive mechanism to stop running and controls the cleaning mechanism to start, thus achieving automatic cleaning. This simplifies the operation process and improves the timeliness and automation of cleaning. Attached Figure Description

[0021] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0022] refer to Figure 1-3A positioner for a welding fixture includes a drive mechanism 1, a triggering mechanism 2, and a cleaning mechanism 3. The drive mechanism 1 includes a drive housing 11, a fixed housing 16, and a fixture system 18. The fixture system 18 is rotatably connected to the inside of the drive housing 11 via a driven gear 14. A drive gear 13 is meshed with the lower part of the driven gear 14. The triggering mechanism 2 includes a rotating rod 22 and a push switch 23. The push switch 23 is installed inside the drive housing 11. A turntable 21 is fixedly connected to one side of the driven gear 14, and the rotating rod 22 is fixedly connected to the side surface of the turntable 21. The cleaning mechanism 3 includes a high-pressure blower 36. A fixed plate 32 is fixedly connected to the lower part of the inner side of the drive housing 11. A sliding block 35 is slidably connected to the upper surface of the fixed plate 32. The high-pressure blower 36 is fixedly connected to the upper surface of the sliding block 35. Through the cleaning mechanism 3, the drive gear 13 is driven to rotate by a first drive motor 12, thereby causing the driven gear 14 to rotate. The clamping system 18 is rotated 180 degrees so that the welding surface is facing down. The second drive motor 31 drives the screw 34 to rotate, causing the sliding block 35 to slide in the sliding groove 33 towards the other side. This causes the high-pressure blower 36, which is fixedly installed on the upper surface of the sliding block 35, to blow high-pressure air upwards. The high-pressure air cleans different positions on the welding surface, significantly improving the cleaning efficiency and clamping accuracy of the welding clamp. Through the trigger mechanism 2, the first drive motor 12 drives the driven gear 14 to rotate through the drive gear 13. As the clamping system 18 rotates downwards, the driven gear 14 drives the turntable 21 to rotate, causing the rotating rod 22 to rotate downwards. After the rotating rod 22 rotates downwards, it triggers the press switch 23. The press switch 23 controls the drive mechanism 1 to stop running and controls the cleaning mechanism 3 to start, realizing automatic cleaning. This simplifies the operation process and improves the timeliness and automation of cleaning.

[0023] Example 1: A rotating seat 17 is fixedly connected to the upper surface of the fixed housing 16. The clamping system 18 is rotatably connected between the rotating seat 17 and the driven gear 14 via a rotating shaft 15. A first drive motor 12 is fixedly connected to the inner side of the drive housing 11. The driving gear 13 is drivenly connected to the output end of the first drive motor 12.

[0024] Example 2: A second drive motor 31 is fixedly connected to the lower inner side of the drive housing 11. A sliding groove 33 is opened in the middle of the surface of the fixed plate 32. A screw 34 is driven to the output end of the second drive motor 31. The screw 34 is rotatably connected to the inside of the sliding groove 33. A sliding block 35 is threaded to the surface of the screw 34. Limiting grooves 37 are opened through both sides of the surface of the fixed plate 32. A limiting rod 38 is fixedly connected inside the limiting groove 37. A limiting block 39 is slidably connected to the surface of the limiting rod 38. The limiting block 39 is fixedly connected to the lower surface of the high-pressure blower 36. A filter screen is fixedly installed at the air outlet on the upper surface of the high-pressure blower 36. The push switch 23 is electrically connected to the first drive motor 12, the second drive motor 31 and the high-pressure blower 36 through an external power supply. When the rotating rod 22 rotates to the push switch 23, the push switch 23 is triggered. At this time, the first drive motor 12 stops running, and the second drive motor 31 and the high-pressure blower 36 start running synchronously to achieve automatic cleaning.

[0025] In operation, the first drive motor 12 is started first, and the drive gear 13 connected to its output end rotates accordingly. The drive gear 13 meshes with the driven gear 14, driving the driven gear 14 to rotate. The rotation of the driven gear 14 directly drives the fixture system 18 to rotate 180 degrees, so that the surface to be welded faces down. At the same time, the rotation of the driven gear 14 also drives the turntable 21 fixedly connected to its side surface to rotate synchronously. The rotating rod 22 on the turntable 21 swings downward accordingly. When the rotating rod 22 rotates to the downward position and contacts the push switch 23 installed inside the drive housing 11, the push switch 23 is triggered. Through its electrical connection with the external power supply and each motor, the push switch 23 immediately sends a stop signal to the first drive motor 12, causing the fixture system 18 to stop rotating, and simultaneously sends a start signal to the second drive motor 31 and the high-pressure blower 36. After the second drive motor 31 starts, the screw 34 connected to its output end begins to rotate. The screw 34 rotates inside the sliding groove 33 in the middle part of the fixed plate 32. Since the sliding block 35 is threadedly connected to the surface of the screw 34, the rotation of the screw 34 drives the sliding block 35 to slide along the sliding groove 33 to the other side. During the sliding process, the limiting block 39 fixedly connected to the lower surface of the sliding block 35 slides along the limiting rod 38 inside the limiting groove 37 that is opened through both sides of the surface of the fixed plate 32, ensuring the stability of the movement of the sliding block 35 and preventing it from rotating or deviating from the track. As the sliding block 35 moves, the high-pressure blower 36 fixedly installed on its upper surface also moves. The filter screen fixedly installed at the air outlet on the upper surface of the high-pressure blower 36 prevents welding impurities blown off from above from falling into the blower and affecting its normal operation, effectively removing slag and spatter from the surface. The entire process realizes an automated process from the fixture flipping into place to the automatic cleaning completion.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
