DETAILED DESCRIPTION

[0034] The present invention Figures 1 to 10As shown, a stator flat wire cutting machine includes a clamping jig mechanism 40 for placing a stator and clamping the stator flat wire, a first transport mechanism 20 for transporting the stator to the clamping jig mechanism 40, an opening and closing drive mechanism 50 for driving the clamping jig mechanism 40 to clamp or release the stator flat wire, a lifting mechanism 60 for lifting the clamping jig mechanism 40 so that the clamping jig mechanism 40 cooperates with the opening and closing drive mechanism 50, a conveying mechanism 70 for conveying the clamping jig mechanism 40, a cutting mechanism 80 for cutting the stator flat wire, and a second transport mechanism 30 for transporting the clamping jig mechanism 40 on the conveying mechanism 70 to the cutting mechanism 80; wherein:

[0035] The frame 10 is provided with a workbench 11 for installing the first conveying mechanism 20, the opening and closing drive mechanism 50, the lifting mechanism 60, the transmission mechanism 70, the second conveying mechanism 30 and the cutting mechanism 80; the opening and closing drive mechanism 50 is located beside the transmission mechanism 70; the lifting mechanism 60 is located below the transmission mechanism 70; and the second conveying mechanism 30 is located between the transmission mechanism 70 and the cutting mechanism 80.

[0036] The conveying mechanism 70 includes a conveying drive motor and a conveying belt, and the conveying belt is installed at the output end of the conveying drive motor.

[0037] The first conveying mechanism 20 and the second conveying mechanism 30 both include a bracket 31, a transverse drive assembly 32, a vertical drive assembly 33 and a clamping cylinder 34. The transverse drive assembly 32 is installed on the bracket 31, the vertical drive assembly 33 is installed at the output end of the transverse drive assembly 32, and the clamping cylinder 34 is installed at the output end of the vertical drive assembly 33.

[0038] The horizontal drive assembly 32 and the vertical drive assembly 33 both include a drive motor, a screw and a slide. The screw is installed on the shaft end of the drive motor and rotates with the slide. The slide serves as the output end. The clamping cylinder 34 is installed on the slide of the vertical drive assembly 33.

[0039] The horizontal drive assembly 32 drives the vertical drive assembly 33 and the clamping cylinder 34 to move horizontally, and the vertical drive assembly 33 drives the clamping cylinder 34 to move vertically, meeting the position movement requirements of the stator and the wire clamping fixture mechanism 40.

[0040] By adopting the first conveying mechanism 20, the wire clamping jig mechanism 40, the opening and closing drive mechanism 50, the lifting mechanism 60, the conveying mechanism 70, the second conveying mechanism 30 and the cutting mechanism 80, the conveying of the stator, the clamping of the stator flat wire by the wire clamping jig mechanism 40, the conveying of the wire clamping jig mechanism 40, the conveying of the wire clamping jig mechanism 40 and the cutting of the stator flat wire are realized, thereby improving the cutting accuracy and reducing the defective rate; the overall structure is compact and occupies a small area.

[0041] The clamping fixture mechanism 40 includes a mounting seat 41, a first clamping disc 42, a second clamping disc 43, a first push rod 422, a second push rod 432, a first connecting rod 423 and a second connecting rod 433. The first clamping disc 42 and the second clamping disc 43 are stacked and distributed on the mounting seat 41. The first clamping disc 42 and the second clamping disc 43 rotate relative to each other. The first push rod 422 is fastened to the first clamping disc 42, and the second push rod 432 is fastened to the second clamping disc 43. The rear end of the first push rod 422 is connected to the The left end of the first connecting rod 423 is hinged; the rear end of the second push rod 432 is hinged to the right end of the second connecting rod 433; the right end of the first connecting rod 423 is hinged to the left end of the second connecting rod 433; a pin hole 44 is provided at the connection position between the first connecting rod 423 and the second connecting rod 433; the opening and closing drive mechanism 50 has a pin column 53 matching the pin hole 44, and the opening and closing drive mechanism 50 drives the first clamping disc 42 and the second clamping disc 43 to rotate in opposite directions or relative directions to clamp or loosen the stator flat wire through the pin column 53.

[0042] The jacking mechanism 60 drives the wire clamping jig mechanism 40 to rise, and the pin hole 44 of the wire clamping jig mechanism 40 is sleeved on the outside of the pin column 53. The opening and closing driving mechanism 50 drives the pin column 53 to move laterally. When the pin column 53 drives the pin hole 44 to move laterally inward, the first connecting rod 423 and the second connecting rod 433 move inward accordingly, and the first push rod 422 and the second push rod 432 move away from each other. The first push rod 422 and the second push rod 432 drive the first wire clamping disc 42 and the second wire clamping disc 43 to rotate in opposite directions to clamp the stator flat wire; when the pin column 53 drives the pin hole 44 to move laterally outward, the first connecting rod 423 and the second connecting rod 433 move outward accordingly, and the first push rod 422 and the second push rod 432 move closer to each other. The first push rod 422 and the second push rod 432 drive the first wire clamping disc 42 and the second wire clamping disc 43 to rotate in opposite directions to loosen the stator flat wire.

[0043] By adopting the wire clamping jig mechanism 40, the opening and closing drive mechanism 50 and the lifting mechanism 60, the lifting of the wire clamping jig mechanism 40 and the opening and closing of the wire clamping jig mechanism 40 are automatically realized, thereby meeting the functional requirements of the wire clamping jig mechanism 40 for clamping and loosening the stator flat wire. The overall structure is compact and occupies a small area. By adopting the pin 53 and the pin hole 44, the opening and closing drive mechanism 50 can detachably drive the wire clamping jig mechanism 40 to clamp or loosen the stator flat wire, thereby preventing the opening and closing drive mechanism 50 from interfering with the position of the wire clamping jig mechanism 40 when the wire clamping jig mechanism 40 needs to move.

[0044] The lifting mechanism 60 includes a support seat 61, a lifting drive cylinder 62 and a lifting plate 63. The lifting drive cylinder 62 is vertically installed on the support seat 61, and the lifting plate 63 is installed on the axial end of the lifting drive cylinder 62. The lifting plate 63 can be lifted to abut against the wire clamping fixture mechanism 40.

[0045] The lifting drive cylinder 62 drives the lifting plate 63 to rise, and the lifting plate 63 drives the wire clamping jig mechanism 40 to rise, so that the pin hole 44 corresponds to the pin column 53, which facilitates the opening and closing drive mechanism 50 to drive the wire clamping jig mechanism 40 to clamp or loosen the stator flat wire; by adopting the lifting mechanism 60, the lifting position movement requirements of the wire clamping jig mechanism 40 are met, so that the wire clamping jig mechanism 40 and the opening and closing drive mechanism 50 can correspond to each other in a detachable manner.

[0046] The first wire clamping disc 42 is provided with a first wire release groove 421, and the second wire clamping disc 43 is provided with a second wire release groove 431. The stator flat wire passes through the first wire release groove 421 and the second wire release groove 431 from top to bottom in sequence, and a wire accommodating gap for accommodating the flat wire is formed at the staggered positions of the first wire release groove 421 and the second wire release groove 431; the first wire release groove 421 and the second wire release groove 431 are staggered relative to each other to reduce the wire accommodating gap so as to clamp the flat wire.

[0047] In the initial state, the first wire-releasing groove 421 and the second wire-releasing groove 431 are positioned opposite to each other, and the second wire-releasing groove 431 is located below the first wire-releasing groove 421. When the first wire-clamping disc 42 and the second wire-clamping disc 43 rotate in opposite directions, the first wire-releasing groove 421 and the second wire-releasing groove 431 are staggered from each other, so that the wire-accommodating gap becomes smaller, thereby achieving clamping of the flat wire; when the first wire-clamping disc 42 and the second wire-clamping disc 43 rotate in opposite directions, the first wire-releasing groove 421 and the second wire-releasing groove 431 are gradually reset, so that the wire-accommodating gap gradually increases. When the wire-accommodating gap is maximum, it corresponds to the size of the first wire-releasing groove 421 and the second wire-releasing groove 431, thereby achieving loosening of the stator flat wire.

[0048] The opening and closing drive mechanism 50 further includes a support 51 and a transverse drive cylinder 52 . The transverse drive cylinder 52 is mounted on the support 51 , and the pin 53 is mounted on the output end of the transverse drive cylinder 52 .

[0049] The opening and closing drive mechanisms 50 are divided into two groups, and the two groups of opening and closing drive mechanisms 50 are symmetrically distributed on both sides of the wire clamping fixture mechanism 40 ; the use of two groups of opening and closing drive mechanisms 50 improves balance.

[0050] A limiting assembly 45 is provided on the mounting seat 41 , and the limiting assembly 45 includes a telescopic spring 451 and a limiting block 452 . The lower end of the telescopic spring 451 is connected to the mounting seat 41 , and the upper end of the telescopic spring 451 is connected to the limiting block 452 . The limiting block 452 is detachably located in the pin hole 44 .

[0051] The upper end of the limit block 452 is provided with a slope 4521 for abutting against the lower side wall of the pin hole 44. The lower side wall of the pin hole 44 can be laterally moved to abut against the slope 4521 to drive the limit block 452 to descend. The telescopic spring 451 drives the limit block 452 to rise and be located in the pin hole 44.

[0052] The lateral drive cylinder 52 drives the pin 53 to move lateraly, and the lateral movement of the pin 53 drives the first connecting rod 423 and the second connecting rod 433 to move lateraly through the pin hole 44; when the pin 53 moves inward, the lower side wall of the pin hole 44 moves lateraly to abut against the inclined surface 4521, and the lower side wall of the pin hole 44 drives the limit block 452 to move downward. When the pin hole 44 moves to a position corresponding to the limit block 452, the telescopic spring 451 drives the limit block 452 to rise and reset, and the limit block 452 rises to the inside of the pin hole 44 , to limit the pin hole 44, the pin 53 and the pin hole 44 can be separated, and the stator flat wire is in a clamped state at this time; when the stator flat wire needs to be loosened, the pin 53 corresponds to the pin hole 44, the pin 53 presses down the limit block 452, the limit block 452 drops and disengages from the pin hole 44, and the pin 53 drives the pin hole 44 to move laterally outward, thereby loosening the stator flat wire; by adopting the limit assembly 45, the limit and unlocking of the pin hole 44 are automatically realized, the operation is simple and convenient, the overall structure is compact, and the area occupied is small.

[0053] When the limit block 452 is detachably located in the pin hole 44, the angle between the first link 423 and the second link 433 is 180 degrees; when the angle between the first link 423 and the second link 433 is 180 degrees, the limit block 452 is located in the middle position between the first link 423 and the second link 433, reducing the driving force of the first link 423 and the second link 433 on the limit block 452 and increasing stability.

[0054] The cutting mechanism 80 includes a cutting support 81, a rotary drive assembly 82, a tangent assembly 83 and a discharge plate 84 for placing the wire clamping fixture mechanism 40. The rotary drive assembly 82 is installed on the cutting support 81, the tangent assembly 83 is installed at the output end of the rotary drive assembly 82, and the discharge plate 84 can be elastically lifted and lowered above the tangent assembly 83.

[0055] The tangent assembly 83 includes a mounting block 831, a tangent drive cylinder 832 and a cutter 833. The tangent drive cylinder 832 is arranged on the mounting block 831, and the cutter 833 is installed on the shaft end of the tangent drive cylinder 832; the mounting block 831 is provided with a plurality of threading grooves 8311 for the lower end of the stator flat wire to pass through, and the cutter 833 can be movably cut off the flat wire below the threading groove 8311.

[0056] The rotary drive assembly 82 includes a rotary drive motor 821 and a rotary disk 822 . The rotary drive motor 821 is mounted on the trimming support 81 . The rotary disk 822 is mounted on the shaft end of the rotary drive motor 821 . The rotary disk 822 is rotatably located on the trimming support 81 .

[0057] The tangent assembly 83 is divided into four groups, and the four groups of tangent assemblies 83 are evenly spaced. A spring is provided between the discharge plate 84 and the cutting support 81. The second conveying mechanism 30 conveys the wire clamping fixture mechanism 40 on which the stator is placed to the upper surface of the discharge plate 84. The vertical drive assembly 33 of the second conveying assembly drives the wire clamping fixture mechanism 40 and the discharge plate 84 to descend synchronously. As the stator descends, the lower end of the stator flat wire passes through the threading groove 8311 to prevent the position of the stator flat wire from shifting. The tangent drive cylinder 832 drives the cutter 833 to thread the wire. The flat wire at the lower end of the slot 8311 is cut off; after the wire cutting is completed, the slide of the vertical drive assembly 33 of the second conveying mechanism 30 rises, the spring drives the discharge plate 84 to rise, and the wire clamping fixture mechanism 40 and the stator rise synchronously; since the stator flat wire has several columns, after cutting one column, the wire cutting assembly 83 is rotated a certain angle to facilitate the cutting of the next column of flat wires; the drive motor is selected to drive the rotating disk 822 to rotate, and the wire cutting assembly 83 rotates with the rotating disk 822 to correspond to the next column of stator flat wires, and the cycle is repeated to cut all the columns of stator flat wires.

[0058] By adopting the rotary drive component 82, the rotation of the tangent component 83 is achieved, which meets the position movement requirement when tangenting the stator flat wire; by adopting the discharge plate 84 that can be elastically lifted and lowered above the tangent component 83, the lifting and lowering of the wire clamping fixture mechanism 40 is achieved, and the stator flat wire is aligned with the tangent component 83, thereby improving the tangent accuracy.

[0059] The stator flat wire cutting machine's cutting method comprises the following steps:

[0060] First, the wire clamping jig mechanism is located on the conveying mechanism, the lifting mechanism drives the wire clamping jig mechanism to rise so that it contacts the opening and closing driving mechanism, the opening and closing driving mechanism drives the wire clamping jig mechanism to an open state, and the first transporting mechanism transports the stator to the wire clamping jig mechanism;

[0061] Second, the opening and closing drive mechanism drives the wire clamping fixture mechanism to clamp the lower side of the stator flat wire; the lifting mechanism drives the wire clamping fixture mechanism to descend onto the conveying mechanism, and the wire clamping fixture mechanism is disengaged from the opening and closing drive mechanism;

[0062] Third, the conveying mechanism conveys the wire clamping fixture mechanism with the stator placed thereon to the second transport mechanism;

[0063] Fourth, the second transport mechanism transports the wire clamping fixture mechanism with the stator placed on it to the top of the cutting mechanism;

[0064] Fifth, the flattening mechanism flattens the lower end of the stator flat wire.

[0065] The design focus of the present invention is that the stator is transported, the stator flat wire is clamped by the wire clamping jig mechanism, the wire clamping jig mechanism is transported, the stator flat wire is transported, the wire clamping jig mechanism is transported, and the stator flat wire is trimmed, thereby improving the trimming accuracy and reducing the defective rate; the overall structure is compact and occupies a small area; by adopting the wire clamping jig assembly, the opening and closing drive assembly and the jacking assembly, the lifting of the wire clamping jig assembly and the opening and closing of the wire clamping jig assembly are automatically realized, thereby meeting the functional requirements of the wire clamping jig assembly for clamping and loosening the stator flat wire, and the overall structure is compact.

[0066] The above description is merely a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any minor modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
