Description

Technical Field

[0001] The utility model relates to the technical field of welding clamping, in particular to a welding clamping device for a generator stator component. Background Art

[0002] The generator stator is the stationary part of the motor. Its components mainly include iron core, frame, coil and other parts. The generator stator is one of the key parts of the generator. For high-voltage and large-capacity synchronous motors, a rotating magnetic pole structure is adopted. Since the capacity and voltage of the excitation part are often much smaller than the armature, the armature is installed on the stator and the main magnetic pole is installed on the rotor. The generator stator mainly acts on the rotating magnetic field formed by the rotor to cut the magnetic field to generate voltage.

[0003] For example, the Chinese utility model patent with patent publication number CN213998366U includes a fixed disk, a slide groove is provided in the middle of the fixed disk, two movable blocks are movably installed inside the slide groove, the inner sides of the two movable blocks are provided with tooth grooves, and a gear is movably installed in the middle of the annular groove. This patent can be used to fix the generator stator component and the clamping plate in advance when in use, and the rotation of the main shaft can be driven by turning on the motor. The gear rotates with the drive of the main shaft, and the movable block follows the gear rotation and moves relative to the annular groove with the drive of the gear. At this time, the generator stator component rotates accordingly, and the welding device can be fixed in the same position. Welding can be achieved by rotating the stator component, thereby achieving the advantage of automatically rotating the generator stator component to achieve welding. However, when fixing the stator component, it is necessary to clamp the outer surface of the stator, which will cause certain obstructions to welding. At the same time, the stator can only rotate around the fixed disk, that is, the rotation direction of the gear. After the stator is fixed, a part of it will be close to the fixed disk, which is not convenient for operation. In view of this, we propose a welding clamping device for the stator component of the generator. Utility Model Content

[0004] The utility model aims to solve at least one of the technical problems existing in the prior art and to provide a welding clamping device for a generator stator component, which can solve the problem that clamping the outer surface of the stator causes certain obstructions to welding.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a welding clamping device for a generator stator component, comprising a processing table, the upper surface of the processing table is provided with a mounting cylinder, the outer surface of the mounting cylinder is provided with a sliding groove extending into the interior thereof, the top wall of the mounting cylinder is rotatably connected with a two-way threaded rod, the outer surface of the two-way threaded rod is threadedly sleeved with a displacement ring, the inner wall of the sliding groove is rotatably connected with a fixed shaft, the outer surface of the fixed shaft is sleeved with a clamping plate, a torsion spring is fixedly connected between the clamping plate and the inner wall of the sliding groove, the outer surface of the displacement ring is fixedly connected with a driving plate, the driving plate extends out of the mounting cylinder through the sliding groove, the driving plate is slidably connected to the inner wall of the sliding groove, the lower end of the two-way threaded rod is fixedly connected with a sleeve, the lower surface of the processing table is fixedly connected with a support frame, and a driving assembly is arranged on the support frame.

[0006] Preferably, the driving assembly includes a motor, which is fixedly connected to the upper surface of the support frame. A through groove is provided on the upper surface of the processing table. The lower end of the mounting tube movably passes through the lower surface of the processing table through the through groove, and the lower end of the sleeve rotates to pass through the lower surface of the mounting tube.

[0007] Preferably, a driving rod is slidably sleeved on the inner wall of the sleeve, the lower end of the driving rod is fixedly connected to the output end of the motor, and a supporting ring is fixedly connected to the lower surface of the mounting cylinder.

[0008] Preferably, an annular groove is provided on the lower surface of the support ring, and a connecting ring is rotatably sleeved on the inner wall of the annular groove.

[0009] Preferably, a lifting ring is fixedly connected to the lower surface of the connecting ring, and an electric telescopic rod is fixedly connected to the lower surface of the processing table.

[0010] Preferably, the output end of the electric telescopic rod is fixedly connected to the upper surface of the lifting ring, and the inner wall of the through groove is provided with a rotation groove.

[0011] Preferably, the inner wall of the rotating groove is rotatably connected with a worm gear, and the worm gear is slidably sleeved on the outer surface of the mounting cylinder.

[0012] Preferably, a worm is meshingly connected to the outer surface of the worm wheel, and the right end of the worm rotates to penetrate the right side surface of the processing table.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] (1) The generator stator component welding clamping device, when clamping the stator component, is sleeved on the outer surface of the mounting tube, and then the sleeve is driven to rotate by the driving assembly. When the sleeve rotates, it will synchronously drive the two-way threaded rod to rotate. Since the displacement ring is restricted in its movement trajectory by the driving plate, when the two-way threaded rod rotates, it will synchronously drive the two displacement rings to move in opposite directions, and then the displacement ring is used to drive the driving plate to move. After the driving plate moves, it squeezes the clamping plate, so that the clamping plate rotates around the fixed axis. When the clamping plate rotates, it will synchronously compress the torsion spring. At the same time, when the clamping plate rotates, its far end gradually moves away from the mounting tube, thereby completing the positioning and clamping of the stator component. Through the above structure, the stator component can be clamped without blocking the outer surface, thereby avoiding blocking the part that needs to be welded. At the same time, since there are two groups of clamping plates, and the upper and lower mirror images are distributed, it can be ensured that the stator is always perpendicular to the upper surface of the processing table during the welding process.

[0015] (2) The welding clamping device of the generator stator component will synchronously drive the installation tube to rotate when the worm gear rotates, and with the help of the installation tube, drive its internal structure to rotate together, thereby driving the stator as a whole to rotate. When welding to the bottom, the lifting ring can be driven to rise by the electric telescopic rod. When the lifting ring rises, it will drive the installation tube to rise with the help of the support ring, thereby completing the lifting of the stator. Through the above structure, not only can the stator be rotated during the welding process, but the stator can also be controlled to rise when welding to the bottom, thereby avoiding the problem of increased welding difficulty caused by the bottom of the stator being too close to the upper surface of the processing table.

[0024] This section will describe in detail the specific embodiments of the utility model. The preferred embodiments of the utility model are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the utility model, but it cannot be understood as a limitation on the protection scope of the utility model.

[0025] See also Figure 1-6 The utility model provides a technical solution: a welding clamping device for a generator stator component, comprising a processing table 1, a mounting cylinder 2 is arranged on the upper surface of the processing table 1, a sliding groove 3 extending into the interior of the mounting cylinder 2 is opened on the outer surface of the mounting cylinder 2, a top wall of the mounting cylinder 2 is rotatably connected with a bidirectional threaded rod 4, a displacement ring 5 is threadedly sleeved on the outer surface of the bidirectional threaded rod 4, a fixed shaft 6 is rotatably connected with the inner wall of the sliding groove 3, a clamping plate 7 is sleeved on the outer surface of the fixed shaft 6, a torsion spring 8 is fixedly connected between the clamping plate 7 and the inner wall of the sliding groove 3, a driving plate 9 is fixedly connected to the outer surface of the displacement ring 5, the driving plate 9 extends out of the mounting cylinder 2 through the sliding groove 3, the driving plate 9 is slidably connected to the inner wall of the sliding groove 3, a sleeve 10 is fixedly connected to the lower end of the bidirectional threaded rod 4, a support frame 11 is fixedly connected to the lower surface of the processing table 1, a driving assembly is arranged on the support frame 11, when the stator component is clamped, the stator component is sleeved on the mounting cylinder 2, and a driving assembly is arranged on the support frame 11. The outer surface of the mounting tube 2 is then driven by the driving assembly to drive the sleeve 10 to rotate. When the sleeve 10 rotates, it will synchronously drive the bidirectional threaded rod 4 to rotate. Since the displacement ring 5 is restricted in the movement trajectory by the driving plate 9, when the bidirectional threaded rod 4 rotates, it will synchronously drive the two displacement rings 5 ​​to move in opposite directions, and then use the displacement ring 5 to drive the driving plate 9 to move. After the driving plate 9 moves, it squeezes the clamping plate 7, so that the clamping plate 7 rotates around the fixed axis 6. When the clamping plate 7 rotates, it will synchronously compress the torsion spring 8. At the same time, when the clamping plate 7 rotates out, its distal end gradually moves away from the mounting tube 2, thereby completing the positioning and clamping of the stator component. Through the above structure, it can be ensured that the outer surface will not be blocked when the stator component is clamped, thereby avoiding blocking the part that needs to be welded. At the same time, since there are two groups of clamping plates 7, and the upper and lower mirror images are distributed, it can be ensured that the stator is always perpendicular to the upper surface of the processing table 1 during the welding process.

[0026] Further, the driving assembly includes a motor 12, which is fixedly connected to the upper surface of the support frame 11, a through slot 19 is provided on the upper surface of the processing table 1, the lower end of the mounting cylinder 2 is movably penetrated through the lower surface of the processing table 1 through the through slot 19, the lower end of the sleeve 10 is rotated to penetrate the lower surface of the mounting cylinder 2, a driving rod 13 is slidably sleeved on the inner wall of the sleeve 10, the lower end of the driving rod 13 is fixedly connected to the output end of the motor 12, the lower surface of the mounting cylinder 2 is fixedly connected to a support ring 14, the lower surface of the support ring 14 is provided with an annular groove 15, and the annular groove 15 is provided on the lower surface of the mounting cylinder 2. The inner wall of the groove 15 is rotatably sleeved with a connecting ring 16, and the lower side surface of the connecting ring 16 is fixedly connected to a lifting ring 17. The lower surface of the processing table 1 is fixedly connected to an electric telescopic rod 18, and the output end of the electric telescopic rod 18 is fixedly connected to the upper surface of the lifting ring 17. The inner wall of the through groove 19 is provided with a rotating groove 21, and the inner wall of the rotating groove 21 is rotatably connected to a worm gear 22. The worm gear 22 is slidably sleeved on the outer surface of the mounting tube 2, and the outer surface of the worm gear 22 is meshedly connected with a worm 20. The right end of the worm gear 20 rotates through the right side surface of the processing table 1. The motor 12 has no self-locking function. The motor 12 drives the driving rod 13 to rotate. When the driving rod 13 rotates, the sleeve 10 is driven to rotate synchronously. Since the worm wheel 22 and the worm 20 are self-locking, the mounting tube 2 is locked by the worm wheel 22 and cannot be rotated. Therefore, the sleeve 10 will only drive the bidirectional threaded rod 4 to rotate. At the same time, the worm wheel 22 can be driven to rotate synchronously by the worm 20 when it is necessary to rotate. Since the worm wheel 22 is a sliding sleeve on the outer surface of the mounting tube 2, the mounting tube 2 is driven to rotate synchronously when the worm wheel 22 rotates, and the internal structure of the mounting tube 2 is driven to rotate together, thereby driving the stator to rotate as a whole. When welding to the bottom, the lifting ring 17 can be driven to rise by the electric telescopic rod 18. When the lifting ring 17 rises, the mounting tube 2 is driven to rise with the help of the support ring 14, thereby completing the rise of the stator. Through the above structure, not only can the stator be rotated during the welding process, but also the stator can be controlled to rise when welding to the bottom, thereby avoiding the problem of increased welding difficulty caused by the bottom of the stator being too close to the upper surface of the processing table 1.

[0027] Working principle: When clamping the stator component, the stator component is sleeved on the outer surface of the mounting tube 2, and then the driving assembly is used to drive the sleeve 10 to rotate. When the sleeve 10 rotates, it will synchronously drive the bidirectional threaded rod 4 to rotate. Since the displacement ring 5 is restricted in its movement trajectory by the driving plate 9, when the bidirectional threaded rod 4 rotates, it will synchronously drive the two displacement rings 5 ​​to move in opposite directions, and then use the displacement ring 5 to drive the driving plate 9 to move. After the driving plate 9 moves, it squeezes the clamping plate 7, so that the clamping plate 7 rotates around the fixed axis 6. When the clamping plate 7 rotates, it will synchronously compress the torsion spring 8. At the same time, when the clamping plate 7 rotates out, its distal end gradually moves away from the mounting tube 2, thereby completing the positioning and clamping of the stator component, and the driving rod 13 is driven to rotate by the motor 12. When the driving rod 13 rotates, the sleeve 10 will be driven to rotate synchronously. Since there is a self-locking between the worm wheel 22 and the worm 20, the mounting tube 2 is locked by the worm wheel 22 and cannot rotate. Therefore, the sleeve 10 will only drive the bidirectional threaded rod 4 to rotate. At the same time, when rotation is required, the worm wheel 22 can be driven to rotate synchronously by the worm 20. Since the worm wheel 22 is a sliding sleeve on the outer surface of the mounting tube 2, when the worm wheel 22 rotates, it will synchronously drive the mounting tube 2 to rotate, and with the help of the mounting tube 2, drive its internal structure to rotate together, and then drive the stator to rotate as a whole. When welded to the bottom, the electric telescopic rod 18 can be used to drive the lifting ring 17 to rise. When the lifting ring 17 rises, it will drive the mounting tube 2 to rise with the help of the support ring 14, thereby completing the rise of the stator.

[0028] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
