Detailed Implementation

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] As described in the background section, there are shortcomings in the existing technology. In order to solve the above-mentioned technical problems, this application proposes an electric motor processing device and a processing method for disassembling the stator slot wedge of an electric motor.

[0019] Example 1: Please see Figures 1-5 An electric motor processing device includes a machine tool 1, a stator body 2 and a rotating device 3 for controlling the movement of the stator body 2 are mounted on the machine tool 1, and a processing device 4 and an adjusting device 5 for controlling the movement of the processing device 4 are provided on the machine tool 1. Multiple motor slot wedges 21 are installed on the stator body 2; The adjusting device 5 is fixedly mounted with a machine head 6, and the processing device 4 is mounted on the machine head 6. The processing device 4 includes a cutting component 7, a drawing component 8, and a transmission component 9. The cutting assembly 7 includes multiple cutting blades 71 and multiple top plates 72. The transmission component 9 runs in the forward direction and drives the multiple cutting blades 71 to move outward so that the cutting blades 71 cut the coil at one end of the stator body 2. At the same time, it drives the multiple top plates 72 to move forward so that the motor slot wedge 21 moves forward. The pulling assembly 8 includes multiple positioning rods 81 and multiple pull rods 82. The transmission component 9 runs in the opposite direction, driving the positioning rods 81 to move outward. The motor slot wedge 21 has a positioning groove 83, and the positioning rods 81 match the positioning groove 83, so that the positioning rods 81 drive the motor slot wedge 21 to move outward, and at the same time drive the multiple pull rods 82 to move outward, so that the pull rods 82 pull the coil at the other end of the stator body 2.

[0020] Specifically, the rotating device 3 adjusts one end of the stator body 2 to be located on one side of the machine head 6. Then, the adjusting device 5 drives the machine head 6 into one end of the stator body 2. The transmission component 9 runs in the forward direction, driving multiple cutting blades 71 to move outward. The cutting blades 71 cut the coil at one end of the stator body 2. The transmission component 9 drives multiple top plates 72 to move forward, so that the top plates 72 contact the motor slot wedges 21 and push the motor slot wedges 21 forward synchronously. After the cutting blades 71 have finished cutting the coil, the adjusting device 5 drives the machine head 6 to reset. At the same time as resetting, the cut coil is brought out. Then, the rotating device 3 adjusts the stator body 2 to move forward. The other end of the sub-body 2 is located on one side of the machine head 6. Then, the machine head 6 is driven into the other end of the stator body 2 by the adjustment device 5. The transmission component 9 runs in the opposite direction. Through the one-way transmission between the cutting component 7 and the transmission component 9, the cutting component 7 cannot run. The transmission component 9 drives multiple pull rods 82 to move outward and makes the pull rods 82 located in the coil winding. At the same time, it drives multiple positioning rods 81 to move outward, so that the positioning rods 81 match the positioning grooves 83 on the motor slot wedge 21. At the same time, the machine head 6 is driven to disengage from the stator body 2 by the adjustment device 5, and the coil and the motor slot wedge 21 are driven to disengage from the stator slot in the stator body 2. By setting the transmission component 9, when the cutting component 7 cuts the coil in the stator body 2, it pushes the motor slot wedge 21 out of the stator slot in the stator body 2. Then, when the pulling component 8 pulls out the remaining coil in the stator body 2, the motor slot wedge 21 is pulled out synchronously through the cooperation between the positioning rod 81 and the positioning groove 83. This avoids friction between the motor slot wedge 21 and the coil, thus solving the problem that when the coil is pulled, friction occurs between the coil and the slot wedge in the stator slot, which can cause damage to the surface of the slot wedge.

[0021] Example 2: The difference from Embodiment 1 above is that, see reference Figures 1-2For the aforementioned rotating device 3, the rotating device 3 includes a positioning table 31, and a positioning pressure plate 32 is installed on the top of the positioning table 31 by screws so that the stator body 2 is fixedly installed on the positioning table 31. A first motor 33 is fixedly connected to the bottom of the machine tool 1, and the output end of the first motor 33 is fixedly connected to the bottom of the positioning table 31. Specifically, the stator body 2 is fixedly installed on the positioning table 31 by the positioning plate 32, and then the first motor 33 is used to adjust the port of the stator body 2 to align with one side of the machine head 6. Then, the position of the upper and lower parts of the machine head 6 is adjusted by the adjusting device 5 so that the axis of the machine head 6 is coaxial with the axis of the stator body 2, and the adjusting device 5 drives the machine head 6 into the port of the stator body 2.

[0022] Example 3: The difference from Embodiment 2 described above is that, see reference... Figures 6-9 For the aforementioned cutting assembly 7 and transmission component 9, the cutting assembly 7 also includes a first reciprocating lead screw 73. Multiple slide grooves 74 are provided on the edge of the head 6 near the stator body 2. A slider 75 is fixedly connected to one side of the cutting blade 71. The slider 75 is slidably disposed in the slide groove 74. The first reciprocating lead screw 73 is rotatably disposed in the slide groove 74 through a bearing. The slider 75 is threadedly assembled onto the first reciprocating lead screw 73. The cutting assembly 7 also includes a threaded sleeve 76. The head 6 has multiple inner holes 77 on the side near the stator body 2. A second reciprocating screw 78 is rotatably connected to the inner hole 77 through a bearing. The threaded sleeve 76 is slidably disposed in the inner hole 77 and is threadedly assembled onto the second reciprocating screw 78. A first limiting groove 79 is provided on both sides of the inner wall of the inner hole 77. A first limiting block 70 is fixedly connected to both sides of the threaded sleeve 76. The first limiting block 70 is slidably disposed in the first limiting groove 79. A top plate 72 is fixedly installed at one end of the threaded sleeve 76. The transmission component 9 includes a transmission rod 91, which is rotatably mounted inside the machine head 6 via bearings. The bottom ends of the first reciprocating lead screw 73 and the third reciprocating lead screw 84 are rotatably connected to the first gear 92 via one-way bearings. The outer periphery of the first gear 92 is provided with a first toothed belt 93, which meshes with the first gear 92. The machine head 6 is rotatably connected to the second gear 94 via bearings. The second gear 94 is located inside the first toothed belt 93 and meshes with the first toothed belt 93. The bottom of the second gear 94 is fixedly connected to an extension rod 95. The machine head 6 is rotatably connected to the vertical rod 96 via bearings. The outer periphery of the vertical rod 96 and the extension rod 95 is fitted with a first transmission belt 97. One end of the transmission rod 91 is fixedly connected to a worm gear 98. The outer periphery of the vertical rod 96 is fixedly connected to a worm wheel 99, which meshes with the worm gear 98. The transmission component 9 also includes a second motor 910. One end of the machine head 6 is fixedly connected to an installation chamber 911, which is fixedly installed on the adjustment device 5. The second motor 910 is located in the installation chamber 911 and is fixedly connected to the machine head 6. A main gear 912 is rotatably connected to the machine head 6 through a bearing. The output end of the second motor 910 is fixedly connected to the shaft center of one side of the main gear 912. A driven gear 913 is fixedly connected to the transmission rod 91, which meshes with the main gear 912. One end of the second reciprocating screw 78 is rotatably provided with an extension rod 914 through a one-way bearing. A second transmission belt 915 is sleeved on the extension rod 914 and the transmission rod 91. Specifically, after the machine head 6 enters one end of the stator body 2, the second motor 910 runs in the forward direction, driving the main gear 912 to rotate. Through the meshing connection between the main gear 912 and the driven gear 913, the driven gear 913 is driven to rotate, thereby driving the transmission rod 91 to rotate. Through the meshing connection between the worm 98 at one end of the transmission rod 91 and the worm wheel 99 on the vertical rod 96, the vertical rod 96 is driven to rotate. Through the sleeve connection between the first transmission belt 97 and the extension rod 95 and the vertical rod 96, the extension rod 95 and the second gear 94 at the top of the extension rod 95 are driven to rotate. Through the meshing connection between the second gear 94 and the first toothed belt 93, the first toothed belt 93 is driven to rotate. Through the meshing connection between the first toothed belt 93 and the two first gears 92, the first toothed belt 93 is driven to rotate. The meshing connection between the two gears drives the two first gears 92 to rotate. Since the third reciprocating screw 84 is connected to one of the first gears 92 through a one-way bearing, the third reciprocating screw 84 cannot rotate when the first gear 92 at the bottom of the third reciprocating screw 84 rotates. At the same time, since the first reciprocating screw 73 is connected to the other first gear 92 through a one-way bearing, the first reciprocating screw 73 rotates when the first gear 92 at the bottom of the third reciprocating screw 84 rotates. Through the threaded connection between the first reciprocating screw 73 and the slider 75, the slider 75 is driven to move outward, thereby driving the cutting blade 71 to move outward, and then the cutting blade 71 cuts the coil inside one end of the stator body 2. While the transmission rod 91 rotates, the extension rod 914 is driven to rotate by the second transmission belt 915 sleeved on the transmission rod 91. Since the extension rod 914 is connected to the second reciprocating screw 78 through a one-way bearing, when the extension rod 914 rotates in the forward direction, it drives the second reciprocating screw 78 to rotate. Through the threaded connection between the second reciprocating screw 78 and the threaded sleeve 76, and the sliding connection between the first limiting block 70 and the first limiting groove 79 on both sides of the threaded sleeve 76, the threaded sleeve 76 is driven to move forward, thereby driving the top plate 72 to move forward. Then, the top plate 72 drives the motor slot wedge 21 to move to the other end of the stator body 2. After the cutting blade 71 finishes cutting the coil, the head 6 of the adjusting device 5 is reset, and the second motor 910 continues to run. Through the reciprocating nature of the first reciprocating screw 73 and the second reciprocating screw 78, the cutting blade 71 and the top plate 72 are reset.

[0023] Example 4: The difference from Embodiment 3 above is that, see reference... Figures 6-9 For the aforementioned drawing assembly 8 and transmission component 9, the drawing assembly 8 also includes a third reciprocating lead screw 84. Multiple inner grooves 85 are provided on the outer side of the machine head 6. The pull rod 82 is slidably disposed in the inner groove 85. The third reciprocating lead screw 84 is rotatably disposed in the inner groove 85 through a bearing. A threaded groove 86 is provided at the bottom end of the pull rod 82. The third reciprocating lead screw 84 is disposed in the threaded groove 86. The pull rod 82 is threadedly assembled onto the third reciprocating lead screw 84. Second limiting grooves 87 are provided on both sides of the inner wall of the inner groove 85. Second limiting blocks 88 are fixedly installed on both sides of the pull rod 82. The second limiting blocks 88 are slidably disposed in the second limiting grooves 87. The drawing assembly 8 also includes a fourth reciprocating lead screw 89. The head 6 has multiple guide grooves 810 on the side near the stator body 2. A fixed seat 811 is slidably connected in the guide grooves 810. The fourth reciprocating lead screw 89 is rotatably disposed in the guide grooves 810 through bearings. The fixed seat 811 is threadedly assembled on the fourth reciprocating lead screw 89. The positioning rod 81 is fixedly installed on the fixed seat 811. The transmission component 9 also includes a face gear 916 and a third gear 917. The third gear 917 is located at the bottom end of the fourth reciprocating screw 89 and is rotatably connected to the fourth reciprocating screw 89 through a one-way bearing. The face gear 916 is rotatably located inside the machine head 6 through a bearing. The face gear 916 is meshed with the third gear 917. A connecting rod 918 is fixedly connected between the face gear 916 and the main gear 912. Specifically, after the coil inside one end of the stator body 2 is cut, the first motor 33 runs, driving the positioning table 31 and the stator body 2 to rotate, so that the other end of the stator body 2 is close to the machine head 6. Then, the adjusting device 5 drives the machine head 6 to move into the other end of the stator body 2. At this time, the second motor 910 rotates in the opposite direction, driving the transmission rod 91 to rotate in the opposite direction. Since the first reciprocating lead screw 73 and its bottom first gear 92 rotate through a one-way bearing, and the second reciprocating lead screw 78 and the extension rod 914 rotate through a one-way bearing, the transmission... When the moving rod 91 rotates in the reverse direction, the first reciprocating lead screw 73 and the second reciprocating lead screw 78 cannot rotate. However, the third reciprocating lead screw 84 and the first gear 92 at its bottom rotate through a one-way bearing. Therefore, when the first gear 92 at the bottom of the third reciprocating lead screw 84 rotates in the reverse direction, it drives the third reciprocating lead screw 84 to rotate. Through the threaded connection between the third reciprocating lead screw 84 and the pull rod 82, and the sliding connection between the second limiting block 88 and the second limiting groove 87 on the outer periphery of the pull rod 82, the pull rod 82 is driven to move outward, thereby allowing the pull rod 82 to enter the winding area of ​​the coil. Simultaneously, when the transmission rod 91 rotates in the reverse direction, it drives the connecting rod 918 to rotate, thereby driving the face gear 916 to rotate. Through the meshing connection between the face gear 916 and the third gear 917, the third gear 917 is driven to rotate. Since the third gear 917 is connected to the fourth reciprocating screw 89 through a one-way bearing, when the transmission rod 91 rotates in the forward direction, the third gear 917 does not drive the fourth reciprocating screw 89 to rotate. When the transmission rod 91 rotates in the reverse direction, the third gear 917 drives the fourth reciprocating screw 89 to rotate. Through the threaded connection between the fourth reciprocating screw 89 and the fixed seat 811, the fixed seat 811 and the positioning rod 81 on the fixed seat 811 are driven to move outward, so that the positioning rod 81 coincides with the positioning groove 83 on the motor slot wedge 21. Then, through the adjusting device 5, the machine head 6 is driven to disengage from the stator body 2, and the remaining coils in the stator body 2 and the motor slot wedge 21 are driven to disengage from the stator body 2 at the same time.

[0024] Example 5: See Figures 1-9 This embodiment discloses a processing method for disassembling stator slot wedges of an electric motor, the specific steps of which are as follows: The stator body 2 is adjusted by rotating device 3 so that one end is positioned on one side of the machine head 6. Then, the machine head 6 is driven into one end of the stator body 2 by adjusting device 5. The transmission component 9 moves forward, driving multiple cutting blades 71 to move outward. The cutting blades 71 cut the coil at one end of the stator body 2. The transmission component 9 drives multiple top plates 72 to move forward so that the top plates 72 contact the motor slot wedges 21 and push the motor slot wedges 21 forward synchronously. After the cutting blades 71 have finished cutting the coil, the machine head 6 is reset by adjusting device 5. At the same time as resetting, the cut coil is brought out. Then, the stator body 2 is adjusted by rotating device 3. The other end of the main body 2 is located on one side of the head 6. Then, the head 6 is driven into the other end of the stator body 2 by the adjusting device 5. The transmission component 9 runs in the opposite direction. Through the one-way transmission between the cutting component 7 and the transmission component 9, the cutting component 7 cannot run. The transmission component 9 drives multiple pull rods 82 to move outward and makes the pull rods 82 located in the coil winding. At the same time, it drives multiple positioning rods 81 to move outward, so that the positioning rods 81 match the positioning grooves 83 on the motor slot wedge 21. While the head 6 is driven away from the stator body 2 by the adjusting device 5, the coil and the motor slot wedge 21 are driven away from the stator slot in the stator body 2.

[0025] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
