[0026] The motor coil cutting device according to the embodiment of the utility model will be described in detail below with reference to the accompanying drawings.

[0027] like Figure 1-Figure 3 As shown, the motor coil cutting device according to the embodiment of the utility model includes: a support 1, a clamping part and a cutting part; the support 1 has a rotation function, the support 1 is used to place the iron core, and drive the iron core to rotate along the central axis of the iron core, the clamping part is located on one side of the support 1, the clamping part is used to limit the position of the coil lead-out end, and comb the coil lead-out end, the cutting part is located above the clamping part, and the cutting part is used to cut the combed coil lead-out end.

[0028] In this embodiment, the initial state of the clamping part is above the iron core and close to the iron core. The iron core is placed on the support 1, and then the support 1 is rotated to rotate the multiple coil lead ends on the iron core into the clamping part, and then the clamping part is controlled to limit the position of the coil lead ends. At this time, the clamping part is moved upward. Under the limitation of the clamping part, the gradually upward moving clamping part allows the partially bent coil lead ends to be combed. When the clamping part reaches a certain position, the cutting part is controlled to synchronously cut the multiple coil lead ends to achieve neat cutting of the coil lead ends; the rotating support 1 is used to support the iron core, and the position of the coil lead ends on the iron core is adjusted, so that the multiple coil lead ends can reach the clamping part from one side of the clamping part by rotation, so that the initial position of the clamping part can be located close to the iron core, which is convenient for the clamping part to comb the coil lead ends later. The clamping part is used to comb the multiple coil lead ends, which improves the neatness of the multiple coil lead ends after cutting.

[0029] The clamping part includes: a column 21 and a fixed plate 22; the column 21 is arranged on one side of the support 1, the fixed plate 22 is slidably connected to the column 21, the fixed plate 22 moves back and forth linearly along the axial direction of the iron core, and a fixed block 23 and a moving block 24 are provided on the fixed plate 22, the fixed block 23 and the moving block 24 are arranged opposite to each other, the moving block 24 is slidably connected to the fixed plate 22, and the moving block 24 moves back and forth linearly along the radial direction of the iron core to approach or move away from the fixed block 23.

[0030] A first groove 231 is formed on the side of the fixed block 23 facing the movable block 24, and the first groove 231 passes through the upper and lower surfaces of the fixed block 23. A second groove 241 is formed on the side of the movable block 24 facing the fixed block 23, and the second groove 241 passes through the upper and lower surfaces of the movable block 24. The first groove 231 and the second groove 241 are arranged opposite to each other, and the space between the first groove 231 and the second groove 241 is located on the moving path of multiple coil lead-out ends.

[0031] In this embodiment, a first slide module is provided on the column 21, and the fixed plate 22 is fixed on the output end of the first slide module. The first slide module is used to drive the fixed plate 22 to move up and down. The fixed plate 22 is located on one side of the fixed block 23 and the moving block 24. That is, the other side of the fixed block 23 and the moving block 24 is open, so that when the iron core rotates, multiple coil lead ends enter the first groove 231 and the second groove 241 from the other side of the fixed block 23 and the moving block 24. A second slide module is provided on the fixed plate 22, and the moving block 24 is fixed on the output end of the second slide module. The second slide module is used to drive the moving block 24 to approach or move away from the fixed block 23. ; The second slide module can drive the moving block 24 to be located at the initial station, the first station and the second station. At the initial station, the clamping part is located close to the iron core. At this time, the distance between the first groove 231 and the second groove 241 is the largest, so that multiple coil lead ends can enter; at the first station, there is a large gap between the first groove 231 and the second groove 241. At this time, during the upward movement of the clamping part, it provides expansion space for the bent coil lead ends and reduces the wear on the surface of the coil lead ends; at the second station, the gap between the first groove 231 and the second groove 241 is smaller, so as to concentrate multiple coil lead ends and facilitate subsequent cutting operations.

[0032] Furthermore, the first groove 231 and the second groove 241 are both arcs, and the cross section of the moving block 24 is a C-shaped structure, so that when in the second working position, the moving block 24 is partially embedded in the first groove 231 to reduce the space between the first groove 231 and the second groove 241.

[0033] The cutting part includes a cutter 31 and a stopper 32, which are arranged opposite to each other and are respectively located on both sides of the coil lead-out end. The stopper 32 is used to resist the coil lead-out end to cooperate with the cutter 31 to apply force to the coil lead-out end.

[0034] The stopper 32 includes two baffles, which are arranged at an interval. After the cutter 31 cuts the lead-out end of the coil, the cutter 31 is located between the two baffles.

[0035] In this embodiment, two baffles are used to apply a force relative to the cutter 31 to the coil lead-out ends, so that during the cutting process, the cutting position of the cutter 31 is perpendicular to the cutter 31, which facilitates the application of force by the cutter 31 and makes the cuts of multiple coil lead-out ends flush.

[0036] A mounting plate 41 is provided on the top of the column 21, and two mounting blocks 42 are provided on one side of the mounting plate 41. The two mounting blocks 42 are arranged at intervals, and the gap between the two mounting blocks 42 is not less than the maximum gap between the fixed block 23 and the movable block 24 to avoid interference with the lead-out ends of multiple coils. The cutter 31 and the stopper 32 are respectively installed on the two mounting blocks 42; the cutter 31 and the stopper 32 are respectively slidably connected to the two mounting blocks 42.

[0037] The cutter 31 is connected to a transmission unit, which includes a first rack 51, a second rack 52 and a gear 53. The first rack 51 is fixed to one side of the cutter 31, the second rack 52 is fixed to one side of the stopper 32, and the gear 53 is rotatably connected to the mounting plate 41. The first rack 51 and the second rack 52 are arranged opposite to each other, and the gear 53 is located between the first rack 51 and the second rack 52. The gear 53 is meshed with the first rack 51 and the second rack 52 for transmission.

[0038] In this embodiment, during the movement of the cutter 31 toward the stopper 32, the cutter 31 drives the first rack 51 to move toward the stopper 32. At this time, the gear 53 meshing with the first rack 51 rotates. During the rotation, the gear 53 drives the second rack 52 to move toward the cutter 31. At this time, the moving second rack 52 drives the stopper 32 to approach the cutter 31, thereby achieving the mutual approach between the cutter 31 and the stopper 32, so that the lead-out ends of the multiple coils are located at the center position of the cutter 31 and the stopper 32, further improving the uniformity of the cutting of the lead-out ends of the multiple coils.

[0039] A first protrusion 311 is formed on the side of the cutter 31 facing the moving block 24, and a second protrusion 242 is formed on the side of the moving block 24 facing the cutter 31. After the fixed plate 22 drives the moving block 24 to move upward, the second protrusion 242 and the first protrusion 311 move along the radial direction of the iron core, and the second protrusion 242 is used to push the first protrusion 311 to approach the stop block 32.

[0040] In this embodiment, after the first slide module drives the fixed plate 22 to move upward, the second protrusion 242 abuts against the first protrusion 311, and then the second slide module drives the moving block 24 to further approach the fixed block 23 to reach the second workstation. During this process, the second protrusion 242 pushes the first protrusion 311 to move toward the stop block 32 to drive the cutter 31 to cut the coil lead end.
