Description

Technical Field

[0001] The present application relates to the technical field of stator cropping machines, and in particular to a conveying device for stator cropping machines. Background Art

[0002] The stator is the stationary part of the motor or generator. The stator consists of three parts: the stator core, the stator winding and the frame. The frame is used to fix the core. For a suspended generator, the frame is used to bear the entire weight of the rotating part; the core is part of the generator's magnetic circuit; and the coil forms the generator's circuit.

[0003] Reference Figure 1 The stator winding 1 of the existing motor is mostly wound with multiple strands of wire, and one end where the ends of the wires are concentrated is the cut end 11 of the stator 1. During the processing of the stator 1, the wires of the cut end 11 need to be cut as a whole to make the wire ends flat and convenient for welding. In the related art, a cutter is usually used to cut the wire ends of the cut end 11. The cutter includes a cutting device 2, and the cutting device 2 includes a workbench and a cutting knife. After the stator 1 is wound at the winding station, the cut end 11 is located on the upper side. The stator 1 at the winding station needs to be reversed 180° so that the cut end 11 is located on the lower side, and then moved to the workbench and fixed, and then the wires of the cut end 11 are cut as a whole by the cutting knife to make the wire ends flat. After the cutting is completed, it is manually removed to enter the next process. The reversal, movement and fixation of the stator 1 are all performed manually, which is inconvenient to operate, has low cutting efficiency and high labor costs. Therefore, the present application provides a conveying device for a stator cutter. Utility Model Content

[0045] The following is combined with Figure 1-9 This application is described in further detail.

[0046] The present application embodiment discloses a conveying device for a stator cutting machine. Figure 1-9 A conveying device for a stator cutting machine includes a mounting platform 3, a mounting frame 4, a double-speed chain conveyor 5, a storage platform 6, a holding clamp 7 and an inner support clamp 8.

[0048] The mounting frame 4 is fixedly mounted on the mounting platform 3, and is provided with a first sliding assembly 41, a first lifting assembly 42, a rotating assembly 43, a second sliding assembly 44 and a second lifting assembly 45; the grasping jaws 7 are used to clamp the stator 1 in a state to be clamped, and the first sliding assembly 41 is used to drive the grasping jaws 7 to slide along the length direction of the mounting platform 3, and the sliding direction of the grasping jaws 7 is close to or away from the stator 1 in a state to be clamped; the first lifting assembly 42 is used to drive the grasping jaws 7 to rise and fall, and the rotating assembly 43 is used to drive the grasping jaws 7 to rotate, so that the cut end 11 of the stator 1 is flipped to the lower side.

[0049] The second sliding assembly 44 is used to drive the inner support jaw 8 to slide along the length direction of the mounting table 3, and the sliding direction of the inner support jaw 8 is close to or away from the flipped stator 1. The second lifting assembly 45 is used to drive the inner support jaw 8 to rise and fall. The inner support jaw 8 is used to extend into the interior of the flipped stator 1 and open and fix it to the stator 1. The second sliding assembly 44 can drive the stator 1 fixed with the inner support jaw 8 to move to the cutting device 2 of the head cutting machine.

[0050] When the stator 1 wire needs to be cut, the stator 1 is placed on the storage table 6 and transported by the double-speed chain conveyor 5. When the stator 1 moves to the middle of the double-speed chain conveyor 5 with the storage table 6, the positioning piece blocks the storage table 6 from continuing to be transported to the end of the double-speed chain conveyor 5. Then the lifting cylinder 31 lifts the storage table 6. At this time, the storage table 6 is out of contact with the double-speed chain conveyor 5, and the stator 1 enters a state to be clamped.

[0051] Then the holding clamp 7 moves toward the stator 1 in the clamping state through the first sliding component 41, and then clamps the stator 1, drives the holding clamp 7 to rise through the first lifting component 42, and then drives the holding clamp 7 to flip 180° through the rotating component 43, so that the cutting end 11 of the stator 1 faces downward. Then the first sliding component 41 continues to move one end distance in the direction close to the second sliding component 44 until the stator 1 is directly below the inner support clamp 8, and then the inner support clamp 8 is lowered and extended to the inside of the stator 1 under the action of the second lifting component 45, and the inner support clamp 8 is opened and fixed with the stator 1, and the holding clamp 7 is released and reset under the action of the first sliding component 41 and the first lifting component 42; then the inner support clamp 8 is driven to slide through the second sliding component 44, driving the stator 1 to move to the cutting device for wire cutting. The reversal, movement and fixation of the stator 1 are all automatic, and the operation is convenient, which helps to improve the cutting efficiency and reduce labor costs.

[0053] When the storage table 6 is transported to the middle of the double-speed chain conveyor 5, the piston rod of the positioning electric cylinder 51 extends to abut against the storage table 6 transported to the middle of the double-speed chain conveyor 5, thereby achieving blocking positioning of the storage table 6. When the stator 1 is trimmed, through the reverse cooperation of the inner support jaws 8 and the holding jaws 7, the stator 1 after trimming is first transferred from the inner support jaws 8 to the holding jaws 7, and finally to the storage table 6. The lifting electric cylinder 31 contracts, and the storage table 6 returns to the double-speed chain conveyor 5. The piston rod of the positioning electric cylinder 51 shortens to below the bottom surface of the storage table 6, so that the storage table 6 is normally transported from the double-speed chain conveyor 5 to the next process, thereby achieving unloading.

The end of the second sliding screw 443 away from the second sliding motor 441 is rotatably connected to the mounting frame 4. The second sliding slider 442 is fixedly connected to the two ends of the second slide 444. The second sliding screw 443 passes through the second slider 442 and is threadedly connected to the second slider 442. The bottom of the second slide 444 is provided with a second sliding I-shaped groove 4441 for the sliding I-shaped rod 415 to pass through. The second lifting assembly 45 is arranged on the second slide 444 and is located below the second slide 444. When the inner support jaw 8 needs to slide, the second sliding motor 441 is started to drive the second sliding screw 443 to rotate, driving the second sliding block 442 to slide, thereby driving the second slide table 444 to slide, and further driving the inner support jaw 8 to slide.

[0061] The second lifting assembly 45 includes a second mounting vertical plate 451, a second lifting motor 452, a second lifting screw 453 and a second lifting block 454. The second mounting vertical plate 451 is fixedly connected to the bottom surface of the second slide 444. The second lifting motor 452 is fixedly installed on the top surface of the second slide 444. The rotating shaft of the second lifting motor 452 faces vertically downward. The rotating shaft of the second lifting motor 452 is fixedly connected to the second lifting screw 453 and is used to drive the second lifting screw 453 to rotate. One end of the second lifting screw 453 away from the second lifting motor 452 is rotatably connected to the second mounting vertical plate 451. The second lifting screw 453 passes through the second lifting block 454 and is threadedly connected to the second lifting block 454.

[0062] The second lifting block 454 has a second mounting side plate 4554541 fixedly connected at both ends, a second lifting slot 456 for the second mounting side plate 4554541 to pass through is provided on the side of the second mounting vertical plate 451, a second connecting vertical plate 457 is fixedly connected to the end of the second mounting side plate 4554541 away from the second lifting block 454, two second lifting I-shaped rods 458 are fixedly connected to the side of the second mounting vertical plate 451 away from the second lifting block 454, and a second lifting I-shaped slot 459 for the second lifting I-shaped rod to pass through is provided on the side of the second connecting vertical plate 457 close to the second lifting block 454. The second mounting side plate 4554541 has a horizontal plate 4542 fixedly connected to the side, and a second rotating motor 4543 is fixedly installed on the top surface of the horizontal plate 4542, and the rotating shaft of the second rotating motor 4543 is vertically downward and fixedly connected to the inner support clamp 8.

[0063] When the inner support clamp 8 needs to be raised or lowered, the second lifting motor 452 is started to drive the second lifting screw 453 to rotate, thereby driving the second lifting block 454 to rise or fall, and then driving the second connecting vertical plate 457 to rise or fall, so as to achieve the lifting or falling of the inner support clamp 8. After the stator 1 has been trimmed once, the second rotating motor 4543 drives the inner support clamp 8 to rotate a specified angle, so as to trim the wires at the remaining positions, until all the wire trimming is completed.

[0064] The implementation principle of the conveying device for the stator cutting machine in the embodiment of the present application is as follows: when the stator 1 wire needs to be cut, the stator 1 is placed on the storage table 6 and transported by the double-speed chain conveyor 5. When the stator 1 moves to the middle of the double-speed chain conveyor 5 with the storage table 6, the positioning member blocks the storage table 6 from continuing to be transported to the end of the double-speed chain conveyor 5. Then, the lifting electric cylinder 31 lifts the storage table 6. At this time, the storage table 6 is out of contact with the double-speed chain conveyor 5, and the stator 1 enters a state to be clamped.

[0065] Then the gripping jaw 7 moves toward the stator 1 in the gripping state through the first sliding assembly 41, and then clamps the stator 1, drives the gripping jaw 7 to rise through the first lifting assembly 42, and then drives the gripping jaw 7 to flip 180 degrees through the rotating assembly 43, so that the cut end 11 of the stator 1 faces downward;

[0066] Then the first sliding assembly 41 continues to move a distance toward the second sliding assembly 44 until the stator 1 is directly below the inner support jaw 8. Then the inner support jaw 8 is lowered and extended to the inside of the stator 1 under the action of the second lifting assembly 45. The inner support jaw 8 is opened and fixed to the stator 1. The holding jaw 7 is released and reset under the action of the first sliding assembly 41 and the first lifting assembly 42. Then the inner support jaw 8 is driven to slide by the second sliding assembly 44, and the stator 1 is driven to move to the head cutting device for wire head cutting. The reversal, movement and fixation of the stator 1 are all automatic, and the operation is convenient, which helps to improve the head cutting efficiency and reduce labor costs.

[0067] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
