[0004] To achieve the above objectives, the technical solution adopted in this application is: to provide an end-line cutting mechanism, comprising: Machine tool; A fixture for supporting the stator and fixing the end wires of the stator; A mobile platform is used to support the lifting and rotation of the fixture so that the end wire is moved to the position to be cut, and the mobile platform is mounted on the machine base; A cutting assembly for cutting the end line at the location to be cut; An adjustment component is used to adjust the vertical distance between the shearing component and the axis of the moving platform.

Furthermore, the use of an adjustment component allows for the adjustment of the vertical distance between the shearing assembly and the stator axis, adapting to different stator diameters and thus enabling the shearing process of end lines from stators of different sizes.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0028] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0029] Please refer to the following: Figures 1 to 3 The end wire trimming mechanism provided in this application embodiment will now be described. The end wire trimming mechanism includes a machine base 10, a fixture 20, a moving platform 30, a cutting assembly 40, and an adjusting assembly 50; the fixture 20 is used to support the stator 70 and fix the end wire 71 of the stator 70; the moving platform 30 and the adjusting assembly 50 are mounted on the machine base 10; please refer to the following documents. Figure 5 The moving platform 30 is used to adjust the height and rotation angle of the fixture 20 so that the end line 71 moves to the position to be cut 401. The moving platform 30 supports the lifting and rotation of the fixture 20. The cutting assembly 40 is used to cut the end line 71 at the position to be cut 401. The adjusting assembly 50 is used to adjust the vertical distance between the cutting assembly 40 and the axis of the stator 70. The power output end of the adjusting assembly 50 is connected to the cutting assembly 40.

[0030] It should be noted that the fixture 20 and the moving platform 30 are separable structures. The fixture 20 is sized to match the stator 70 to be processed. When the size of the stator 70 changes, the matching fixture 20 can be used to ensure the fixation of its end line 71. After fixing the stator 70 to the fixture 20, the fixture 20 is mounted on the moving platform 30. The moving platform 30 can adjust the height and rotation angle of the fixture 20, thereby adjusting the height and rotation angle of the stator 70, so that the end line 71 of the stator 70 moves to the shearing position 401. The shearing position 401 can be understood as the position where the end line 71 is located during the shearing operation of the shearing assembly 40, that is, the position directly opposite the shearing assembly 40 along the radial direction of the stator. The axis of the moving platform 30 refers to the axis of rotation of the moving platform 30 when adjusting the rotation angle of the fixture 20, which is the axis of the stator 70 when the end line 71 is sheared. When the adjusting component 50 moves the shearing component 40 to a position above and matching the stator 70, the moving platform 30 drives the fixture 20 to rise up to the end line 71 and reach the shearing position 401. Then, the shearing component 40 shears the end line 71 at the shearing position 401. After the shearing component 40 completes one shearing, the moving platform 30 lowers the fixture 20 until the end line 71 is below the shearing component 40. Then, the moving platform 30 rotates the fixture 20 until the next end line 71 is below the shearing position 401. Next, the moving platform 30 rises the fixture 20 to the next end line 71 and reaches the shearing position 401, where the shearing component 40 shears the next end line 71. This process is repeated until all end lines 71 are sheared.

[0031] In this embodiment, the jig 20 allows for easy fixing of stators 70 of different sizes onto the moving platform 30, preventing relative sliding of the stators 70 on the moving platform 30 and maintaining the stability of the stators 70's position on the moving platform 30, thus facilitating the control of the accuracy of the end line 71's position. The moving platform 30 allows for adjustment of the height and rotation angle of the end lines 71, enabling sequential movement of each end line 71 to the corresponding position on the shearing assembly 40, accommodating the shearing requirements of end lines 71 with different spacings, and supporting stators 70 of different heights. The adjusting assembly 50 allows for adjustment of the vertical distance between the shearing assembly 40 and the axis of the stator 70, adapting to different stator 70 diameters, thereby enabling the shearing process of end lines 71 with different sizes of stators 70 and different end line spacings. Compared to the existing technology where the ring cutter head and ring clamping assembly are installed on the machine base and can only be adapted to the shearing operation of specific stator models, the end line cutting flattening mechanism in this application embodiment only needs to select a matching fixture 20 when cutting the end line 71 of different stators 70, which helps to improve the compatibility of the end line cutting flattening mechanism and reduce the cost of production equipment.

[0032] In one embodiment of this application, please refer to Figure 3 , Figure 5 and Figure 6 The shearing assembly 40 includes a positioning plate 41, a cutter 42, a first driver 43, and a base plate 44. The cutter 42 is mounted on the side of the positioning plate 41 away from the moving platform 30. The first driver 43 drives the cutter 42 to reciprocate radially along the moving platform 30. The positioning plate 41 and the first driver 43 are mounted on the base plate 44. The positioning plate 41 has a positioning hole 411 for positioning the end line 71. The cutter 42 cuts the end line 71 extending out of the positioning hole 411. The power output end of the first driver 43 is connected to the cutter 42. The positioning plate 41 stops the top of the positioning fixture 20 to control the height position of the stator 70. After the end line 71 is inserted into the positioning hole 411, part of the end line 71 extends out of the positioning hole 411 to the upper side of the positioning plate 41. The first driver 43 drives the cutter 42 to cut off the part of the end line 71 extending out of the positioning hole 411. In this way, the positioning hole 411 can prevent the end line 71 from bending and deforming when the cutter 42 cuts it.

[0033] Optionally, the first driver 43 is a linear driver, such as a cylinder, electro-hydraulic actuator, or electric cylinder. In this way, the first driver 43 can drive the cutter 42 to reciprocate along the radial direction of the stator 70 to achieve cutting of the end line 71.

[0034] In one embodiment of this application, please refer to Figures 5 to 7 There are multiple positioning holes 411, which are arranged radially along the stator 70. In this way, the multiple positioning holes 411 can correspond to multiple end lines 71 arranged along the radial direction of the stator 70.

[0035] In one embodiment of this application, please refer to Figures 5 to 7 The positioning plate 41 has through holes 412 on both sides of the cutter 42 along the width direction for inserting the end wire 71. The through holes 412 are used for inserting the end wire 71 on both sides of the position to be cut 401. This helps to maintain the stability of the end wire 71 and the positioning plate 41 during the cutting process, and also avoids interference between the end wire 71 on both sides of the position to be cut 401 and the positioning plate 41. Optionally, the positioning hole 411 is gradually widened on the side near the fixture 20, and the through hole 412 is gradually widened on the side near the fixture 20, so as to facilitate the insertion of the end wire 71 into the positioning hole 411 and the through hole 412.

[0036] In one embodiment of this application, please refer to Figures 5 to 7The positioning plate 41 has side plates 413 on both sides of the positioning hole 411. The side plates 413 are located on the side of the positioning plate 41 away from the fixture 20, and a sliding cavity 414 is formed between the two side plates 413. The cutter 42 is slidably inserted into the sliding cavity 414. The side plates 413 can enhance the structural strength of the positioning plate 41 and prevent the positioning plate 41 from deforming during the shearing process. The sliding cavity 414 can guide the cutter 42 to slide radially along the stator 70 so as to maintain the perpendicularity of the cutting end line 71. Specifically, each side plate 413 has a limiting plate on the side away from the positioning hole 411. The limiting plate can restrict the upward movement of the cutter 42, so that the cutter 42 slides close to the upper surface of the positioning plate 41.

[0037] In one embodiment of this application, please refer to Figures 5 to 7 The positioning plate 41 is detachably connected to the base plate 44. The positioning plate 41 and the base plate 44 can be connected by screws, clips, or other means. This facilitates the replacement and maintenance of the positioning plate 41 to match different stators 70 and makes maintenance easier.

[0038] In one embodiment of this application, please refer to Figures 5 to 7 The shearing assembly 40 also includes a cutter head holder 45 and a slide rail 46. The slide rail 46 is slidably connected to the cutter head holder 45. One end of the cutter head holder 45 is connected to the cutter 42, and the other end is connected to the power output end of the first driver 43. The slide rail 46 is mounted on the base plate 44 and is arranged along the length direction of the cutter 42 (i.e., the cutting direction of the cutter 42). This facilitates controlling the linear movement of the cutter 42. Optionally, a T-slot is formed between the slide rail 46 and the base plate 44, and the bottom of the cutter head holder 45 is adapted to the T-slot. This restricts the vertical movement of the cutter head holder 45.

[0039] In one embodiment of this application, please refer to Figures 1 to 3 The adjusting assembly 50 includes a nut 51 connected to the base plate 44, a screw 52 threaded to the nut 51, a second driver 53 for driving the screw 52 to rotate, and a support frame 54 supporting the second driver 53. The screw 52 is rotatably mounted on the support frame 54, the base plate 44 is slidably connected to the support frame 54, the power output end of the second driver 53 is connected to the screw 52, ​​and the support frame 54 is mounted on the machine base 10. This allows the second driver 53 to drive the screw 52 to rotate, enabling precise control of the position of the nut 51, thus facilitating accurate control of the vertical distance between the shearing assembly 40 and the stator 70. Optionally, guide rails 55 are respectively mounted on both ends of the support frame 54 of the base plate 44, and sliders 56 are respectively mounted on the base plate 44 that slidably engage with each guide rail 55. The sliding engagement between the guide rails 55 and the sliders 56 guides the base plate 44 to move linearly, improving the stability of the base plate 44 and facilitating precise control of the position of the shearing assembly 40.

[0040] In one embodiment of this application, please refer to Figures 1 to 3 The fixture 20 includes a support base 21 and a positioning ring 22. The support base 21 supports the stator 70, and the positioning ring 22 fixes the end wires 71. The support base 21 has a limiting hole 211, and the moving platform 30 has a limiting post 311 that is inserted into the limiting hole 211. The positioning ring 22 is detachably connected to the support base 21, and the positioning ring 22 has a wire hole 221 that corresponds one-to-one with each end wire 71. In this way, the stator 70 can be loaded onto the moving platform 30 by the fixture 20 to keep the position of the end wires 71 stable, so as to move each end wire 71 to the position 401 to be cut.

[0041] In one embodiment of this application, please refer to Figures 1 to 3 The end wire cutting mechanism also includes a chip removal assembly 60 for suctioning and shearing waste chips. The suction end of the chip removal assembly 60 is mounted on the shearing assembly 40, and the suction end of the chip removal assembly 60 covers the position 401 to be sheared. This allows the waste chips to be removed in a timely manner to prevent them from interfering with the shearing of the end wire 71.

[0042] Optionally, the chip removal assembly 60 includes a housing and a vacuum fan, with the vacuum fan connected to the housing via an air pipe, and the housing covering the positioning plate 41. The vacuum generated by the vacuum fan draws suction from inside the housing, thereby removing the sheared waste chips. Of course, a vacuum generator or similar device can also be used to achieve the vacuum suction effect.

[0043] In one embodiment of this application, please refer to Figure 1 , Figure 2 and Figure 4 The mobile platform 30 includes a support plate 31, a third driver 32, a first bracket 33, a fourth driver 34, and a second bracket 35.

The power output end of the fourth driver 34 is connected to the first bracket 33, and the power output end of the third driver 32 is connected to the support plate 31. The first bracket 33 and the second bracket 35 are slidably connected. In this way, the fixture 20 can be driven to rise, fall, and rotate, so as to control the position and rotation angle of the stator 70.

[0044] Optionally, the first support 33 is provided with a sliding rod 37, and the second support 35 is provided with a sliding sleeve 36, which is slidably fitted onto the sliding rod 37. In this way, the first support 33 can be guided to rise and fall, which helps to improve the stability of the first support 33 and the second support 35.

[0045] Optionally, the limiting post 311 is provided on the support plate 31, and the top of the limiting post 311 is chamfered; the limiting hole 211 is gradually widened at the end near the support plate 31. In this way, it is convenient to load the jig 20 onto the support plate 31.
