[0002] An armature includes a winding sleeved on an armature shaft and a commutator, and the groove between the winding and the commutator riser is welded; the commutator, as a vulnerable device on the armature, is prone to welding failure with the winding and wear after long-term use. In the usual replacement operation, the entire armature is directly scrapped, and such a practice will also scrap the still good components on the armature, which is not conducive to resource reuse; similarly, there is also a replacement process for the commutator to avoid excessive waste, while the traditional replacement process for the commutator requires manual operation of instruments for milling, extraction and other operations, with low work efficiency and unable to be replaced in large quantities. Summary of the Invention

[0005] The beneficial effect of the present invention lies in: through the control of the milling mechanism and the pressing-out mechanism by the controller, the winding on the armature is clamped by the milling clamp, the riser of the commutator is cut by the milling cutter to release the connection between the commutator and the winding, and then under the clamping of the commutator by the pressing-out mechanism, the pressing rod presses into the central axis of the commutator, so that the part of the armature except the clamped commutator is pushed to one side, thereby removing the commutator; thereafter, a new commutator can be welded according to the existing commutator assembly process.

[0017] To describe in detail the technical content, achieved objectives and effects of the present invention, the following is described in conjunction with the embodiments and with reference to the drawings.

[0018] Please refer to Figures 1 to 4 , a commutator replacement device for an armature, where a welded winding 11 and a commutator 12 are provided on the armature 1, including a milling mechanism 2, a pressing-out mechanism 3 and a controller; the controller is electrically connected to the milling mechanism 2 and the pressing-out mechanism 3; the milling mechanism 2 includes a milling clamping member 21 and a milling cutter 22, and the pressing-out mechanism 3 includes a pressing-out clamping member 31 and a pressing rod 32; the milling clamping member 21 is used to clamp the winding 11, and the riser of the commutator 12 faces the milling cutter 22; the pressing-out clamping member 31 is used to clamp the commutator 12, and the pressing rod 32 presses into the center axis of the commutator 12.

[0019] As can be seen from the above description, the beneficial effects of the present invention are as follows: By controlling the milling mechanism 2 and the pressing mechanism 3 with a controller, the winding 11 on the armature 1 is clamped by the milling clamp 21, and the riser of the commutator 12 is cut by the milling cutter 22 to release the connection between the commutator 12 and the winding 11. Then, under the clamping of the commutator 12 by the pressing mechanism 3, the pressing rod 32 presses into the middle axis of the commutator 12, so that the part of the armature 1 except the clamped commutator 12 is pushed to one side, and thus the commutator 12 is removed; thereafter, a new commutator 12 can be welded according to the existing assembly process of the commutator 12. The above realizes the automated operation of the commutator 12 replacement operation, saves a large amount of human resources, and can achieve large-scale processing.

[0020] Further, it further includes a moving slide 4. A moving slide 4 is connected between the milling mechanism 2 and the pressing mechanism 3, and the pressing clamp 31 moves in the length direction of the moving slide 4.

[0021] As can be seen from the above description, through the setting of the moving slide 4, it is convenient for the transfer of the armature 1 between the milling mechanism 2 and the pressing mechanism 3; there is no need to set an additional clamping and moving device. After the milling mechanism 2 processes the armature 1, the pressing clamp 31 can clamp the commutator 12 of the armature 1 and move it along the moving slide 4 to the pressing rod 32 of the pressing mechanism 3, and the pressing rod 32 further operates on the armature 1.

[0022] Further, the center lines of the pressing clamp 31 and the milling clamp 21 at the milling mechanism 2 coincide; the winding 11 is clamped on the milling clamp 21, and the peripheral surface of the commutator 12 faces the pressing clamp 31.

[0023] As can be seen from the above description, due to the arrangement that the center lines of the pressing clamp 31 and the milling clamp 21 coincide at the milling mechanism 2, after the milling mechanism 2 finishes operating on the armature 1, the pressing clamp 31 can immediately operate to clamp and transfer the commutator 12, saving processing time.

[0024] Further, the pressing clamp 31 and the milling clamp 21 at the milling mechanism 2 respectively clamp the winding 11 and the commutator 12.

[0025] As can be seen from the above description, during the milling operation, the pressing clamp 31 and the milling clamp 21 respectively clamp the armature 1, improving the stability during the milling operation and ensuring milling accuracy.

[0026] Further, when the pressing clamp 31 clamps the commutator 12, the width of its projection on the axial direction of the armature 1 is greater than the width of the armature 1.

[0027] As described above, through the projection arrangement of the extrusion clamping member 31, the waste materials during the milling process can be resisted by the extrusion clamping member 31 and fall down, avoiding the splashing of waste materials, which is not conducive to sorting and cleaning.

[0028] Further, the milling clamping member 21 includes elastic jaws 211 and a center height positioning device. The milling mechanism 2 further includes a fixed seat 213. The elastic jaws 211 are rotatably provided on the fixed seat 213, and the elastic jaws 211 clamp one end of the armature 1; the center height positioning device clamps the winding 11.

[0029] As described above, by clamping one end of the armature 1 with the elastic jaws 211 and clamping the winding 11 of the armature 1 with the center height positioning device, the clamping at multiple positions ensures the stability during the milling process; at the same time, the relative position between different riser segments on the commutator 12 and the milling cutter 22 is controlled by the rotation of the elastic jaws 211.

[0030] Further, the center height positioning device includes a first moving seat 2121, a second moving seat 2122, a first roller 2123, a second roller 2124, and an adjusting screw rod 2125. Opposite first and second threads are provided at intervals on the adjusting screw rod 2125. The first moving seat 2121 and the second moving seat 2122 are respectively engaged with the first thread and the second thread. A rotatable first roller 2123 is provided on the first moving seat 2121, and a rotatable second roller 2124 is provided on the second moving seat 2122; the circumferential surface of the winding 11 is clamped by the first roller 2123 and the second roller 2124.

[0031] As described above, after the armature 1 is placed in the center height positioning device, the controller rotates the adjusting screw rod 2125, so that the first moving seat 2121 and the second moving seat 2122 move towards each other under the cooperation of the first thread and the second thread, and then the first roller 2123 and the second roller 2124 move towards each other to lift the armature 1 and ensure its central position until one end of the armature 1 is opposite to the elastic jaws 211, and the elastic jaws 211 clamp one end of the armature 1.

[0032] Further, the extrusion clamping member 31 includes two extrusion clamping blocks 311 moving towards each other. V-shaped grooves are provided on the opposite surfaces of the two extrusion clamping blocks 311; the commutator 12 is clamped between the V-shaped grooves of the two extrusion clamping blocks 311.

[0033] As described above, the commutator 12 is clamped by the two extrusion clamping blocks 311 moving towards each other, and the setting of the V-shaped grooves enables the extrusion clamping blocks 311 to adapt to commutators 12 of different sizes.

[0034] Further, the extrusion clamping member 31 further includes a mounting platform 312 and a force - increasing device 313. The extrusion clamping block 311 and the force - increasing device 313 are arranged on the mounting platform 312. The force - increasing device 313 includes a first base 3131, a second base 3132, a moving rod 3133, a spring 3134, and a transmission member 3135. The first base 3131 and the second base 3132 are arranged on one side of the extrusion clamping block 311 perpendicular to its moving direction. The first base 3131 and the second base 3132 are opposite to each other and connected with the moving rod 3133. A spring 3134 is sleeved on the moving rod 3133, and the two ends of the spring 3134 are respectively abutted against the first base 3131 and the second base 3132. The second base 3132 moves towards the first base 3131 along the moving rod 3133. The transmission member 3135 is hinged between the extrusion clamping block 311 and the second base 3132.

[0035] As can be seen from the above description, by setting the force - increasing device 313, when the two extrusion clamping blocks 311 clamp the commutator 12, they can be strengthened to clamp the commutator 12 under the action of the force - increasing device 313. Specifically, after the two extrusion clamping blocks 311 clamp the commutator 12, due to the restoring action of the spring 3134 sleeved on the moving rod 3133, the second base 3132 has a tendency to move away from the first base 3131, and then is transmitted to the extrusion clamping block 311 through the transmission member 3135, so that the two extrusion clamping blocks 311 move further towards each other to clamp the commutator 12.

[0036] Further, the force - increasing device 313 further includes a limit post 3136. The limit post 3136 is fixedly arranged on the mounting platform 312. The transmission member 3135 is L - shaped. The two ends of the transmission member 3135 are respectively hinged to the extrusion clamping block 311 and the second base 3132, and the corner of the transmission member 3135 is sleeved on the limit post 3136.

[0037] As can be seen from the above description, through the L - shaped setting of the transmission member 3135 and its cooperation with the limit post 3136, the moving range of the force - increasing device 313 and the extrusion clamping block 311 is limited, avoiding excessive movement and interfering with other structures and over - clamping the commutator 12.

[0038] Refer to Figures 1 to 4 , the first embodiment of the present invention is:

[0039] The application scenario of the present invention: When it is necessary to replace the damaged armature 1 of the commutator 12, the traditional replacement of the commutator 12 requires manual operation of instruments for milling, extraction and other operations, with low work efficiency and unable to be replaced in large quantities.

[0040] Such as Figures 1 to 4As shown in the figure, the commutator replacement device on the armature of this embodiment includes the armature 1 to be replaced, a milling mechanism 2, a pressing-out mechanism 3, a moving slide 4, and a controller.

[0041] The controller is electrically connected to the milling mechanism 2 and the pressing-out mechanism 3.

[0042] As Figure 1 shown in the figure, the armature 1 is provided with a welded winding 11 and a commutator 12, and both the winding 11 and the commutator 12 are sleeved on the rotating shaft of the armature 1.

[0043] As Figure 1 shown in the figure, the milling mechanism 2 includes a milling clamp 21, a fixed seat 213, a milling cutter 22, and a milling cutter 22 mounting seat. The milling clamp 21 includes an elastic jaw 211 and a center height adjustment device 212. The center height adjustment device 212 is arranged between the fixed seat 213 and the milling cutter 22 mounting seat. The elastic jaw 211 is rotatably arranged on one side of the fixed seat 213 facing the center height adjustment device 212, and the milling cutter 22 is movably arranged on the milling cutter 22 mounting seat.

[0044] As Figure 4 shown in the figure, the center height adjustment device 212 includes a first moving seat 2121, a second moving seat 2122, a first roller 2123, a second roller 2124, and an adjusting screw rod 2125. Opposite first threads and second threads are arranged at intervals on the adjusting screw rod 2125. The first moving seat 2121 and the second moving seat 2122 are respectively matched with the first thread and the second thread. A rotating first roller 2123 is arranged on the first moving seat 2121, and a rotating second roller 2124 is arranged on the second moving seat 2122.

[0045] The winding 11 of the armature 1 to be processed is clamped by the first roller 2123 and the second roller 2124 of the center height adjustment device 212, and one end of the armature 1 is clamped by the elastic jaw 211. After the above clamping and fixing, the riser of the commutator 12 is milled by the milling cutter 22, and the milling position is adjusted by rotating the elastic jaw 211 under the control of the controller.

[0046] As Figure 1 and Figure 2 shown in the figure, the pressing-out mechanism 3 is arranged on one side of the milling mechanism 2. A moving slide 4 is arranged between the pressing-out mechanism 3 and the milling mechanism 2. The pressing-out mechanism 3 includes a pressing-out clamp 31 and a pressing rod 32. The pressing-out clamp 31 is movable along the moving slide 4.

[0047] Before milling the armature 1, the pressing-out clamping member 31 moves along the moving slide 4 to the milling mechanism 2. The center line of the pressing-out clamping member 31 coincides with the center line of the milling clamping member 21. After the elastic clamping jaws 211 and the center height adjusting device 212 clamp the armature 1, the pressing-out clamping member 31 also clamps the commutator 12 to improve the stability during milling. When the armature 1 rotates, the pressing-out clamping member 31 releases the clamping to allow the armature 1 to rotate.

[0048] As Figure 2 shown, during the milling process, since the width of the projection of the pressing-out clamping member 31 on the axial direction of the armature 1 is greater than the width of the armature 1, the waste cut by the milling cutter 22 will be blocked by the pressing-out clamping member 31 and fall, avoiding splashing.

[0049] After milling is completed, the milling clamping member 21 releases the clamping of the armature 1. The elastic clamping jaws 211 loosen one end of the armature 1, while the center height adjusting device 212 causes the first roller 2123 and the second roller 2124 to descend under the action of the adjusting screw rod 2125, only maintaining the clamping of the pressing-out clamping member 31 on the commutator 12 of the armature 1.

[0050] As Figure 1 shown, the pressing-out clamping member 31 moves the commutator 12 of the armature 1 along the moving slide 4 to the pressing-out mechanism 3, making the pressing rod 32 opposite to the central axis of the commutator 12.

[0051] As Figure 2 and Figure 3 shown, the pressing-out clamping member 31 includes two pressing-out clamping blocks 311 moving towards each other, a mounting platform 312, a force-increasing device 313, and a limit post 3136.

[0052] The pressing-out clamping blocks 311, the force-increasing device 313, and the limit post 3136 are arranged on the mounting platform 312. The opposite surfaces of the two pressing-out clamping blocks 311 are provided with V-shaped grooves. During clamping, the commutator 12 is clamped between the V-shaped grooves of the two pressing-out clamping blocks 311.

[0053] The force-increasing device 313 includes a first base 3131, a second base 3132, a moving rod 3133, a spring 3134, and a transmission member 3135. The first base 3131 and the second base 3132 are arranged on one side of the pressing-out clamping block 311 perpendicular to its moving direction. The first base 3131 and the second base 3132 are opposite and connected with a moving rod 3133. A spring 3134 is sleeved on the moving rod 3133, and both ends of the spring 3134 are abutted against the first base 3131 and the second base 3132 respectively. The second base 3132 moves towards the first base 3131 along the moving rod 3133. There are two transmission members 3135, which are correspondingly hinged between a pressing-out clamping block 311 and the second base 3132.

[0054] Specifically, the transmission member 3135 is L-shaped. The two ends of the transmission member 3135 are respectively hinged to the extrusion clamping block 311 and the second base 3132, and the corner of the transmission member 3135 is sleeved with a limit post 3136.

[0055] Working principle of the present invention: When it is necessary to replace the commutator 12 on the armature 1, under the operation of the controller, the extrusion clamping member 31 of the extrusion mechanism 3 moves to the milling mechanism 2 and coincides with the center line of the milling clamping member 21 of the milling mechanism 2; thereafter, the armature 1 to be processed is placed on the center height adjustment device 212, and the winding 11 abuts against the first roller 2123 and the second roller 2124 of the center height adjustment device 212; controlled by the controller, the adjusting screw 2125 of the center height adjustment device 212 rotates, so that the first moving seat 2121 and the second moving seat 2122 move towards each other, thereby raising the armature 1 until one end of the armature 1 is opposite to the elastic clamping jaw 211 on the fixed seat 213 of the milling mechanism 2, and the elastic clamping jaw 211 clamps one end of the armature 1; then, under the control of the controller, the extrusion clamping member 31 of the extrusion mechanism 3 also clamps the commutator 12 part of the armature 1 at the same time, thus completing the clamping of the armature 1 during the milling process; thereafter, the milling of different riser segments of the commutator 12 on the armature 1 is realized by the movement of the milling cutter 22, the rotation of the elastic clamping jaw 211 and the engagement and disengagement of the extrusion clamping member 31; the waste during the milling process is blocked by the extrusion clamping member 31 to avoid splashing.

[0056] After milling, the elastic clamping jaw 211 releases the clamping of one end of the armature 1, the center height adjustment device 212 descends, the extrusion clamping member 31 moves along the moving slide 4 to the extrusion mechanism 3, and the armature 1 is transferred to the extrusion mechanism 3; the pressure rod 32 of the extrusion mechanism 3 is pressed into the central axis of the armature 1 under the drive of the air cylinder, and the structure other than the commutator 12 is pushed away, thereby releasing the installation of the commutator 12 on the armature 1.

[0057] During the process of the extrusion clamping member 31 clamping the commutator 12, under the cooperation of the first base 3131, the second base 3132, the moving rod 3133, the spring 3134 and the transmission member 3135 of the force increasing device 313, the two extrusion clamping blocks 311 move further towards each other, effectively clamping the commutator 12.

[0058] Thereafter, a new commutator 12 is assembled and welded, that is, the replacement operation is completed.

[0059] In summary, a commutator replacement device on an armature provided by the present invention controls a milling mechanism and a pressing-out mechanism through a controller. The winding on the armature is clamped by a milling clamping part, and the riser of the commutator is cut by a milling cutter to release the connection between the commutator and the winding. Then, under the clamping of the commutator by the pressing-out mechanism, a pressing rod presses into the central axis of the commutator, so that the part of the armature other than the clamped commutator is pushed to one side, and thus the commutator is removed. After that, a new commutator can be welded according to the existing commutator assembly process. The above realizes the automated operation of the commutator replacement operation, saves a large amount of human resources, and can achieve large-scale processing.

[0060] The above are only embodiments of the present invention, and do not limit the patent scope of the present invention. Any equivalent transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in the relevant technical fields, shall be equally included in the patent protection scope of the present invention.
