[0026] In order to make the objectives, technical solutions and advantages of the present invention more clear and understandable, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention, that is, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Usually, the components of the embodiments of the present invention described and shown in the accompanying drawings herein can be arranged and designed in various different configurations.

[0027] Therefore, the detailed description of the embodiments of the present invention provided in the accompanying drawings below is not intended to limit the scope of the claimed present invention, but merely represents the selected embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0028] The following in conjunction with Figures 1-9Describe the specific implementation of the present invention. A fully automatic split-type stator coil numerical control bending machine includes a machine body 11. A limiting mechanism is provided on one side of the machine body 11, and a bending mechanism 13 is provided on each of the two sides of the limiting mechanism. The bending mechanism 13 includes a mounting plate 14, and a limiting pin 17 and a bending plate 19 are detachably mounted on the mounting plate 14. The limiting mechanism includes a pushing plate 23 and a fixing plate 34. A plurality of mutually staggered teeth are respectively fixed on the sides of the pushing plate 23 and the fixing plate 34 that are close to each other. The pushing plate 23 and the fixing plate 34 are slidably connected. A pushing and pressing plate 33 is detachably mounted at one end of the pushing plate 23 close to the fixing plate 34, and a fixing and pressing plate 32 is detachably mounted at one end of the fixing plate 34 close to the pushing plate 23. A calibration mechanism is detachably mounted between the fixing and pressing plate 32 and the pushing and pressing plate 33. The stator coil is in a very flat O-shaped before being bent. It is clamped by the limiting mechanism and then bent by the bending mechanism. The whole process is controlled by a numerical control program with multiple servo motors to achieve fully automatic processing, with high processing efficiency and high bending accuracy. When the pushing plate 23 moves relative to the fixing plate 34, it will apply the same pressure to both sides of the stator coil and will not cause excessive extrusion to the stator coil.

[0029] Beneficially, the bending mechanism 13 further includes a fixing frame 18. The fixing frame 18 is fixedly connected to the mounting plate 14. The limiting pin 17 is fixedly arranged at one end of the fixing frame 18 away from the mounting plate 14. The bending plate 19 is located on the side of the limiting pin 17 away from the fixing frame 18. A bending motor 20 is provided on the side of the bending plate 19 away from the limiting pin 17. The bending motor 20 drives the bending plate 19 through a transmission component 21. The position of the limiting pin 17 determines the length of the bent part of the stator coil. The limiting pin 17 is cylindrical, and it will not damage the stator coil itself when guiding the bending of the stator coil.

[0030] Beneficially, the bending mechanism 13 further includes a rotating motor. The rotating motor is arranged inside the machine body 11. The output shaft of the rotating motor penetrates through the machine body 11 and the mounting plate 14. The output shaft of the rotating motor is rotatably connected to the mounting plate 14. The output shaft of the rotating motor is fixedly connected to a rotating plate 15. The mounting plate 14 is rotatably connected to the rotating plate 15. The transmission component 21 is fixedly connected to the side of the rotating plate 15 away from the mounting plate 14. A bevel gear set is provided inside the transmission component 21. The output end of the transmission component 21 is fixedly connected to the output shaft of the bending motor 20. A first lead screw is fixedly arranged at the output end of the transmission component 21. The bending plate 19 is fixedly connected to the first lead screw. The transmission component 21, as well as the gearbox 29 used later, and the transmission between the control motor 25 and the third lead screw 31 are all similar. A bevel gear set is rotatably arranged inside the box body to achieve power transmission in the vertical direction.

[0031] Beneficially, the limiting mechanism includes a carrier plate 26 which is detachably mounted on the fuselage 11. A slide rail 27 is fixedly provided on one side of the carrier plate 26. A slider 24 is slidably arranged on the slide rail 27. The slider 24 is fixedly connected to the push plate 23. A push block 22 is arranged on the side of the push plate 23 away from the fuselage 11. The push block 22 is fixedly connected to the push plate 23. A propulsion motor 28 is arranged on the side of the push block 22 away from the push plate 23. The propulsion motor 28 is fixedly arranged on the carrier plate 26. The output shaft of the carrier plate 26 drives a second lead screw 30 through a gear box 29. The gear box 29 is fixedly connected to the carrier plate 26. The second lead screw 30 is rotatably connected to the gear box 29. The second lead screw 30 is threadedly connected to the push block 22.

[0032] Beneficially, a control motor 25 is arranged on the side of the carrier plate 26 away from the push plate 23. The control motor 25 is fixedly arranged on one side of the fuselage 11. The output shaft of the control motor 25 drives a third lead screw 31. The third lead screw 31 is threadedly connected to the carrier plate 26. An installation strip 12 is arranged between the carrier plate 26 and the fuselage 11. The installation strip 12 is slidably connected to the fuselage 11. The installation strip 12 is fixedly connected to the transmission shaft 16. The horizontal height of the carrier plate 26 can also be adjusted to meet the bending requirements of stator coils with different thicknesses. When adjusted properly, after the stator coil is placed on the limiting mechanism and clamped and fixed, its uppermost side will always contact the limiting pin 17.

[0033] Beneficially, the two bending mechanisms 13 are symmetrical to each other. The mounting plate 14 of one of the bending mechanisms 13 is fixedly connected to the fuselage 11. The mounting plate 14 of the other bending mechanism 13 is slidably mounted on the fuselage 11 and fixed by bolts. The two bending mechanisms 13 are the same. The purpose is to meet the design requirements of split stator coils. One can adjust the installation position and the other is fixed because it is convenient to maintain the equipment. There is no need to adjust both sides. Although the position of the carrier plate 26 does not change, the longitudinal installation position of the calibration mechanism can be changed, and the purpose of longitudinal adjustment can still be achieved, which is much faster than adjusting the two bending mechanisms 13 simultaneously.

[0034] Advantageously, grooves are provided on one side of the fixed extrusion plate 32 and the pushing extrusion plate 33 that are close to each other, and the calibration mechanism is provided in the grooves. The calibration mechanism includes two mounting blocks 41 detachably mounted in the grooves. One of the mounting blocks 41 is fixed to the fixed extrusion plate 32, and the other mounting block 41 is fixed to the pushing extrusion plate 33. The two mounting blocks 41 are arranged along the length direction of the groove, and a floating gear 44 is provided between the two mounting blocks; teeth are provided on one side of the two mounting blocks 41 that are close to each other and are respectively engaged with both sides of the floating gear 44. The floating gear 44 is fixedly arranged on a rotating shaft 43, and a telescopic arm structure is detachably mounted at one end of the rotating shaft 43 away from the floating gear 44. Both ends of the telescopic arm structure can be telescoped, and the position of the stator coil is changed through its end to make it centered and positioned, without the need for manual additional measurement and calibration of its placement position, improving the bending efficiency.

[0035] Advantageously, the telescopic arm structure includes a first telescopic arm 35, two second telescopic arms 36, two third telescopic arms 37, and two fourth telescopic arms 38. The first telescopic arm 35 is rotatably connected to the rotating shaft 43, and the connection point between the first telescopic arm 35 and the rotating shaft 43 is located at the center point of the bottom surface of the first telescopic arm 35; the two second telescopic arms 36 are respectively slidably arranged at both ends of the first telescopic arm 35, the two third telescopic arms 37 are respectively slidably connected to the two second telescopic arms 36, the two fourth telescopic arms 38 are respectively slidably connected to the two third telescopic arms 37, and a positioning block 39 is respectively fixedly provided at one end of the two fourth telescopic arms 38 that are away from each other. The positioning block 39 has a special arc and is adapted to the inner side of the end of the stator coil.

[0036] Beneficially, a transmission rod 40 is respectively provided on one side of the two mounting blocks 41 away from each other. The transmission rod 40 is located between the mounting block 41 and the first telescopic arm 35. Each transmission rod 40 is connected to the mounting block 41 and the second telescopic arm 36 closest to it; both ends of the transmission rod 40 are hinged to the mounting block 41 and the second telescopic arm 36 respectively; at one end of the second telescopic arm 36 located inside the first telescopic arm 35 and at one end of the third telescopic arm 37 located inside the second telescopic arm 36, a fixed pulley is provided. A first steel rope 45 and a second steel rope 46 are arranged on the two fixed pulleys; both ends of the first steel rope 45 are fixedly connected to one end of the first telescopic arm 35 close to the positioning block 39 and one end of the third telescopic arm 37 away from the positioning block 39 respectively; both ends of the second steel rope 46 are fixedly connected to one end of the second telescopic arm 36 close to the positioning block 39 and one end of the fourth telescopic arm 38 away from the positioning block 39 respectively. The four telescopic arms and the two steel ropes form a rope row telescopic system, which magnifies the movement and saves space. When bending, the telescopic arms can be completely retracted into the groove without affecting the normal bending process; the power source of the telescopic arms comes from the relative displacement of the fixed plate 34 and the pushing plate 23. By controlling the forward and reverse rotation of the programming propulsion motor 28, positioning and clamping can be completed quickly at one time.

[0037] Beneficially, a slide bar 42 is respectively fixedly provided at both ends of the first telescopic arm 35. The two slide bars 42 are respectively slidably arranged on the two mounting blocks 41; the sliding direction of the slide bar 42 relative to the mounting block 41 is perpendicular to the sliding direction of the second telescopic arm 36 relative to the first telescopic arm 35. The slide bar 42 restricts the moving direction of the telescopic arm structure, and the telescopic arm structure cannot swing in the groove, ensuring the positioning effect of the stator coil.

[0038] The working principle of the present invention:

[0039] First, calibrate the equipment and program the bending motor and the rotating motor to meet the requirements of different bending angles of the stator coil; debug the installation position of one of the bending mechanisms 13, and at the same time adjust the installation position of the mounting block 41 relative to the groove (the distance adjusted by the mounting block 41 is equal to half of the distance adjusted by the bending mechanism 13) to meet the bending requirements of stator coils of different lengths;

[0040] After the above part of the debugging is completed, do not adjust it easily; finally, start the control motor 25 to control the rotation of the third lead screw 31. The bearing plate 26 moves along the axis of the third lead screw 31, and the limiting mechanism slides up and down relative to the fuselage 11 as a whole through the mounting strip 12 to meet the bending requirements of stator coils of different thicknesses.

[0041] After all debugging is completed, place the stator coil to be processed on the limiting mechanism. The two sides of the stator coil are respectively located between the gap of the pushing plate 23 and the fixed pressing plate 32 and the gap of the pushing and pressing plate 33 and the fixing plate 34. Both ends of the stator coil extend beyond the fixed pressing plate 32 and the pushing and pressing plate 33, so that the fixed pressing plate 32 and the pushing and pressing plate 33 are all located in the hollow part of the stator coil;

[0042] The propulsion motor 28 is started, and the second lead screw 30 is controlled to rotate through the gearbox 29. The second lead screw 30 drives the slider 22 to move, and the pushing plate 23 moves together with the slider 22; the specific process is that the propulsion motor 28 rotates forward and backward, respectively controlling the pushing plate 23 to first move away from the fixing plate 34 and then approach the fixing plate 34. During this process, the width of the groove first becomes narrower, and the fixed pressing plate 32 and the pushing and pressing plate 33 approach each other, causing the two mounting blocks 41 to have a relative displacement. The floating gear 44 is forced to rotate, but the rotating shaft 43 will always remain in the middle of the fixed pressing plate 32 and the pushing and pressing plate 33. The slide bar 42 and the mounting block 41 slide, and the first telescopic arm 35 always remains parallel to the fixed pressing plate 32 or the pushing and pressing plate 33;

[0043] The rotating shaft 43, the first telescopic arm 35, the second telescopic arm 36, the third telescopic arm 37, the fourth telescopic arm 38 and the positioning block 39 will always maintain synchronous movement in the horizontal direction. The second telescopic arm 36 and the mounting block 41 have a relative displacement. Through the transmission rod 40 (constituting a connecting rod-slider mechanism), the horizontal displacement is transmitted into a vertical displacement, causing the second telescopic arm 36 to slide relative to the first telescopic arm 35;

[0044] Under the action of the first steel rope 45 and the second steel rope 46 (constituting a rope row telescopic system), the third telescopic arm 37 and the fourth telescopic arm 38 will also move. Eventually, the positioning blocks 39 extend out from both ends of the groove until the two positioning blocks 39 abut against both ends of the stator coil. The propulsion motor 28 first pauses and then starts in the reverse direction; before the propulsion motor 28 pauses, the two positioning blocks 39 will calibrate the longitudinal position of the stator coil, making the distances between its two ends and the bending mechanism 13 exactly the same; when placing the stator coil, no additional measurement and judgment are required. The stator coil can be placed at the processing position. After being calibrated by the positioning blocks 39, those with inaccurate placement positions will slide longitudinally relative to the fixed pressing plate 32 and the pushing and pressing plate 33, and finally there will always be a fixed and unified posture;

[0045] The propulsion motor 28 starts in the reverse direction to control the pushing plate 23 to approach the fixing plate 34. According to the above principle, the calibration mechanism resets, and the two positioning blocks 39 return to the inside of the groove; at the same time, the distance between the pushing plate 23 and the fixed pressing plate 32 becomes narrower, and the distance between the pushing and pressing plate 33 and the fixing plate 34 becomes narrower. After the stator coil is clamped and fixed, the propulsion motor 28 stops;

[0046] At this time, both ends of the stator coil are respectively located below the two limit pins 17. The bending motor 20 and the rotating motor cooperate to start, and bend both ends of the stator coil simultaneously. Specifically, the rotating motor drives the transmission shaft 16 to rotate, and the rotating plate 15 rotates together with the transmission shaft 16. The bending motor 20, the transmission assembly 21, and the rotating plate 15 move synchronously. The bending motor 20 makes the bending plate 19 approach the end of the stator coil and bends it through the transmission assembly 21.

[0047] After the bending is completed, the bending motor 20 and the rotating motor reset first, and then the propulsion motor 28 starts to reset. When there is enough gap between the propulsion plate 23 and the fixed pressing plate 32, and between the propulsion pressing plate 33 and the fixed plate 34 for the stator coil to be taken out, the propulsion motor 28 can be stopped (this position is the initial position pre-programmed for the propulsion motor 28). At this time, the two positioning blocks 39 have not yet approached the ends of the stator coil.

[0048] In addition, it should be noted that the transmission methods of the first lead screw, the second lead screw 30, and the third lead screw 31 are all common structures, and the internal structures of the transmission components will not be elaborated (not shown in the figure). As long as the vertical transmission and the circumferential transmission of the axial direction are satisfied, in the embodiments of the present invention, a bevel gear set plus a lead screw connected to the bevel gear coaxially by a spline is used to achieve this.

[0049] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, terms such as "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0050] The above content is only an example and explanation of the structure of the present invention. Those skilled in the art of this technology can make various modifications or supplements to the described specific embodiments or use similar methods to replace them. As long as they do not deviate from the structure of the invention or exceed the scope defined by this claim book, they should all belong to the protection scope of the present invention.
