Description

Technical Field

[0001] This utility model relates to the field of welding technology, and in particular to a multi-angle rotation mechanism for a welding auxiliary platform. Background Technology

[0002] During welding, in order to facilitate the adjustment of the workpiece's posture and place the welding part in an easily operable position, a multi-angle rotation mechanism is used to adjust the angle of the workpiece, allowing it to rotate in both the horizontal and vertical directions. However, this rotation is generally driven by a motor. After stopping, due to inertia, the rotating table may overshoot, meaning the motor cannot stop immediately, causing the rotating table to continue rotating. This results in a shift in the welding position, affecting the welding effect. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies where the motor cannot stop immediately, causing the rotating table to continue rotating, resulting in a shift in the welding position and affecting the welding effect. Therefore, this invention proposes a multi-angle rotation mechanism for a welding auxiliary platform.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: Design a multi-angle rotation mechanism for a welding auxiliary platform, including a base plate, a motor fixedly connected to the upper surface of the base plate, a rotating shaft fixedly connected to the output shaft of the motor, a rotating platform hinged to the upper end of the rotating shaft, a fixing mechanism provided on the upper surface of the rotating platform, the rotating platform being adjusted by an adjustment mechanism, a connecting frame fixedly connected to the upper surface of the base plate, the connecting frame being rotatably connected to the rotating shaft via bearings, and the rotating shaft being abutted by an abutting mechanism.

[0005] Preferably, the fixing mechanism includes a threaded rod, which is rotatably connected to the rotating table via a bearing, and an abutment block is threaded through the threaded rod, which is limited by a limiting mechanism.

[0006] Preferably, the limiting mechanism includes a limiting post, which is fixedly connected to the rotating platform and passes through the rotating platform.

[0007] Preferably, the adjustment mechanism includes a hinge rod, one end of which is hinged to the rotating platform, and the other end of which is hinged to a connecting sleeve. The connecting sleeve is fitted onto the rotating shaft, and a fixed lug is rotatably connected to the connecting sleeve via a connecting bearing. A telescopic rod is fixedly connected between the fixed lug and the base plate.

[0008] Preferably, the abutting mechanism includes two abutting parts, the inner sides of the two abutting parts abutting against the rotating shaft, and the outer sides of the two abutting parts moving through a moving mechanism.

[0009] Preferably, the two abutting portions have an arc-shaped structure.

[0010] Preferably, the moving mechanism includes a threaded sleeve, which is rotatably connected to the connecting frame via a bearing. Both ends of the threaded sleeve are threaded through and connected to threaded posts. The threads of the two threaded posts are in opposite directions. Moving frames are fixedly connected to the opposite outer sides of the two threaded posts. The two moving frames are respectively fixedly connected to two abutment parts.

[0011] Preferably, a limiting rod is fixedly connected to the movable frame, and the limiting rod passes through the movable frame.

[0012] The multi-angle rotation mechanism of the welding auxiliary platform proposed in this utility model has the following advantages: by adopting an abutment mechanism to increase the resistance to the rotation of the shaft, the shaft can be stopped immediately after the motor is powered off, preventing the welding position from shifting and ensuring the welding effect.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Example 1: Refer to Figure 1-4A multi-angle rotation mechanism for a welding auxiliary platform includes a base plate 1. A motor 8, which is a servo motor, is fixedly connected to the upper surface of the base plate 1. A rotating shaft 10 is fixedly connected to the output shaft of the motor 8. A rotating table 2 is hinged to the upper end of the rotating shaft 10. A fixing mechanism is provided on the upper surface of the rotating table 2. The rotating table 2 is adjusted by an adjustment mechanism. A connecting frame 7 is fixedly connected to the upper surface of the base plate 1. The connecting frame 7 is rotatably connected to the rotating shaft 10 through a bearing. The bearing between the connecting frame 7 and the rotating shaft 10 is a thrust ball bearing to support the weight of the rotating table 2. The rotating shaft 10 is abutted by an abutting mechanism. By using an abutting mechanism to increase the resistance to the rotation of the rotating shaft 10, the rotating shaft 10 can be stopped immediately after the motor 8 is de-energized, preventing the welding position from shifting and ensuring the welding effect.

[0017] The fixing mechanism includes a threaded rod 3, which is rotatably connected to the rotating table 2 via a bearing. A contact block 4 is threaded through the threaded rod 3. The contact block 4 is limited by a limiting mechanism. By rotating the threaded rod 3, the contact block 4 is moved, so that the contact block 4 and the rotating table 2 clamp and fix the workpiece.

[0018] The limiting mechanism includes a limiting post 5, which is fixedly connected to the rotating table 2 and passes through the rotating table 2. The limiting post 5 is used to limit the abutment block 4 and prevent the abutment block 4 from shifting.

[0019] Example 2: Refer to Figure 1-4 In another preferred embodiment of this utility model, based on embodiment 1, the adjustment mechanism includes a hinge rod 11. One end of the hinge rod 11 is hinged to the rotating platform 2, and the other end of the hinge rod 11 is hinged to a connecting sleeve 12. The connecting sleeve 12 is sleeved on the rotating shaft 10. A fixed ear 16 is rotatably connected to the connecting sleeve 12 through a connecting bearing 13. A telescopic rod 6 is fixedly connected between the fixed ear 16 and the base plate 1. The telescopic rod 6 extends and retracts, causing the fixed ear 16 to move. The fixed ear 16 causes the connecting sleeve 12 to move, and the connecting sleeve 12 causes the lower end of the hinge rod 11 to move, so that the hinge rod 11 causes the rotating platform 2 to adjust its angle in the vertical direction. The telescopic rod 6 is a hydraulic telescopic rod with a self-locking function, so that the position of the connecting sleeve 12 can be fixed after the movement stops, thereby fixing the vertical angle of the rotating platform 2.

[0020] Example 3: Reference Figure 1-4 As another preferred embodiment of the present invention, based on embodiment 2, the abutting mechanism includes two abutting parts 18, the inner sides of the two abutting parts 18 abut against the rotating shaft 10, and the outer sides of the two abutting parts 18 move through a moving mechanism.

[0021] The two abutment parts 18 have an arc-shaped structure. The moving mechanism includes a threaded sleeve 14, which is rotatably connected to the connecting frame 7 via bearings. Both ends of the threaded sleeve 14 are threadedly connected to threaded posts 15, with the threads of the two threaded posts 15 having opposite directions. Moving frames 9 are fixedly connected to the opposite outer sides of the two threaded posts 15, and the two moving frames 9 are respectively fixedly connected to the two abutment parts 18. A limit rod 17 is fixedly connected to the moving frame 9, and the limit rod 17 passes through the moving frame 9. By clamping with a wrench, the threaded sleeve 14 is rotated, thereby adjusting the position of the two threaded posts 15 within the threaded sleeve 14, so that the two moving frames 9 move towards each other, moving the two abutment parts 18 to abut against the rotating shaft 10, increasing the rotational resistance of the rotating shaft 10, so as to limit and fix the rotating table 2.

[0022] During operation: Place the workpiece under the abutment block 4, rotate the threaded rod 3 to move the abutment block 4, so that the abutment block 4 and the rotating table 2 clamp and fix the workpiece. The motor 8 rotates, which drives the rotating shaft 10 to rotate. The rotating shaft 10 drives the rotating table 2 to rotate, and the horizontal angle of the workpiece on the rotating table 2 is adjusted. The telescopic rod 6 is extended and retracted, which drives the fixed ear 16 to move. The fixed ear 16 drives the connecting sleeve 12 to move. The connecting sleeve 12 drives the lower end of the hinge rod 11 to move, so that the hinge rod 11 drives the rotating table 2 to adjust the angle in the vertical direction, and the workpiece can be adjusted at multiple angles.

[0023] 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.
