[0001] The present disclosure relates to the technical field of motor rotor disassembly and assembly, and in particular, to a motor rotor disassembly device. Background Art

[0002] The motor is an important component in the coal mill, usually consisting of a stator and a rotor. The rotor can rotate under the action of the rotating magnetic field of the stator, thereby driving the output shaft of the motor to rotate, and then driving other equipment connected to the motor (such as the grinding roller in the coal mill) to rotate.

[0003] In order to ensure the normal operation of the equipment, the rotor of the motor usually needs to be inspected and maintained regularly during the use of the motor.

[0011] Optionally, the movable rod includes a rod body and a plurality of oblique rods connected to the rod body, the rod body extends along the axial direction of the motor rotor, the clamping mechanism further includes a plurality of guide structures, and the plurality of oblique rods, the plurality of guide structures and the plurality of clamping parts are arranged in one-to-one correspondence; Each of the clamping parts includes a clamping rod, a clamping block fixed at one end of the clamping rod and a sliding block fixed at the other end of the clamping rod. The multiple clamping blocks are used to clamp the motor rotor together. Each of the clamping rods can be movably passed through the corresponding guide structure and the corresponding inclined rod. A guide groove extending along the radial direction of the rod body is formed on one of the guide structure and the clamping rod. A guide block extending along the radial direction of the rod body is formed on one of the guide structure and the clamping rod. The guide groove is slidably matched with the guide block. The sliding block is located on the side of the inclined rod away from the clamping block, and the sliding block is in contact with the side of the inclined rod away from the clamping block.

[0012] Optionally, the clamping mechanism further comprises a fixing rod and a fixing block mounted at one end of the fixing rod, the fixing rod extends along the axial direction of the motor rotor, and one end of the rod body away from the clamping mechanism movably passes through the fixing block and extends into the fixing rod; The fixed rod is formed with a plurality of guide long holes extending along the axial direction of the fixed rod, and the movable rod further comprises a plurality of guide connecting rods extending along the radial direction of the rod body, the plurality of guide long holes, the plurality of guide connecting rods and the plurality of inclined rods are arranged one by one, one end of each guide connecting rod is connected to the rod body, and one end of each guide connecting rod passes through the corresponding guide long hole and is connected to the corresponding inclined rod; A plurality of guide structures are mounted on the fixing block.

[0013] Optionally, an elastic member is connected between the fixing block and the rod body; One end of the fixed rod away from the movable rod is a closed end, and a one-way valve is arranged on the closed end; Wherein, the one-way valve is detachably arranged on the closed end, or the one-way valve is a one-way valve with adjustable flow direction.

[0014] Optionally, the motor rotor disassembly device further includes a fixing mechanism, which includes a lifting structure and a fixing plate, wherein the lifting structure is connected to the fixing plate and is used to drive the fixing plate to move up and down, and the fixing plate is used to detachably fix the motor housing.

[0015] Through the above technical scheme, since the rotor push rod, the first sleeve and the second sleeve all extend along the axial direction of the motor rotor, a first screw-nut pair is formed between the first sleeve and the second sleeve, a second screw-nut pair is formed between the rotor push rod and the second sleeve, and the first motor and the second motor are respectively connected to the first sleeve and the second sleeve in a transmission manner. By reasonably adjusting the working states of the first motor and the second motor, the rotor disassembly device can be put into different working modes, namely the above-mentioned first working mode and second working mode.

[0017] In addition, since the pitch of the external thread on the outer surface of the second sleeve is greater than the pitch of the external thread on the outer surface of the rotor push rod, the moving speed of the rotor push rod in the first working mode is greater than the moving speed of the rotor push rod in the second working mode. In this way, by switching different working modes of the rotor disassembly device, the disassembly requirements at different stages in the motor rotor disassembly process can be met. For example, when the rotor push rod is far away from the motor rotor, the rotor disassembly device can be adjusted to the first working mode, that is, the second sleeve is driven to move by the first motor and the first sleeve, and then the rotor push rod is driven to move. The moving speed of the rotor push rod is faster, and it can move toward the motor rotor faster and contact the motor rotor, thereby reducing the disassembly time of the motor rotor and improving the disassembly efficiency of the motor rotor. When the rotor push rod contacts the motor rotor or is about to contact the motor rotor, the rotor disassembly device can be adjusted to the second working mode. At this time, the second motor and the second sleeve drive the rotor push rod to move, and the rotor push rod can have a lower moving speed and a larger driving force, so that on the one hand, it is convenient to align the rotor push rod with the motor rotor, and on the other hand, it is convenient to push the motor rotor out of the motor housing, effectively improving the disassembly accuracy of the motor rotor.

[0029] In the description of the present disclosure, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "connect", "connected", and "installed" 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 directly connected or indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present disclosure can be understood according to specific circumstances.

[0030] like Figures 1 to 7As shown, the present disclosure provides a motor rotor disassembly device 100, including a pushing mechanism 1, the pushing mechanism 1 includes a rotor push rod 11, a first sleeve 12, a second sleeve 13, a first motor 14 and a second motor 15, and the rotor push rod 11, the first sleeve 12 and the second sleeve 13 all extend along the axial direction of the motor rotor. One end of the rotor push rod 11 is used to contact the first end of the motor rotor so as to be able to push the motor rotor to move. The first sleeve 12 is sleeved outside the second sleeve 13 and is threadedly connected to the second sleeve 13, and a first screw nut pair is formed between the first sleeve 12 and the second sleeve 13. The second sleeve 13 is sleeved outside the rotor push rod 11 and is threadedly connected to the rotor push rod 11, and a second screw nut pair is formed between the rotor push rod 11 and the second sleeve 13, and the pitch of the external thread on the outer surface of the second sleeve 13 is greater than the pitch of the external thread on the outer surface of the rotor push rod 11. The output shaft of the first motor 14 is in transmission connection with the first sleeve 12, and the output shaft of the second motor 15 is in transmission connection with the second sleeve 13, and the second motor 15 is a self-locking motor. The pushing mechanism 1 has a first working mode and a second working mode. In the first working mode, the second motor 15 is in a self-locking state to limit the rotation of the second sleeve 13, and the first motor 14 drives the first sleeve 12 to rotate so that the second sleeve 13 and the rotor push rod 11 move synchronously. In the second working mode, the second motor 15 drives the second sleeve 13 to rotate so that the rotor push rod 11 moves, and the rotation speed of the output shaft of the first motor 14 is the same as the rotation speed of the first sleeve 12.

[0031] Here, it should be noted that the self-locking motor is a motor with a self-locking function, and its special structure enables the motor to stop running and lock the output shaft immediately once it receives a stop signal or loses power. In other words, when the second motor 15 is not started, the output shaft of the second motor 15 will not rotate under the drive of an external force, so the second sleeve 13 connected to the second motor 15 can be locked, so that the second sleeve 13 cannot rotate.

[0032] In the above-mentioned rotor disassembly device, when the rotor disassembly device is in the first working mode, the output shaft of the first motor 14 rotates, thereby driving the first sleeve 12 to rotate. At this time, since the second motor 15 is in a self-locking state (that is, the output shaft of the second motor 15 is in a locked state), the second sleeve 13 that is transmission-connected to the output shaft of the second motor 15 is restricted by the output shaft of the second motor 15 and cannot rotate. Therefore, the second sleeve 13 can move toward or away from the motor rotor under the rotation of the first sleeve 12, and the second sleeve 13 drives the internal rotor push rod 11 to move toward or away from the motor rotor, so that the rotor push rod 11 can approach the motor rotor or contact the motor rotor.

[0033] When the rotor disassembly device is in the second working mode, the output shaft of the second motor 15 rotates and drives the second sleeve 13 to rotate, and the first sleeve 12 rotates synchronously with the second sleeve 13. At this time, since the rotation speed of the output shaft of the first motor 14 is the same as the rotation speed of the first sleeve 12, the output shaft of the first motor 14 will not interfere with the rotation of the first sleeve 12, and the first sleeve 12 will not interfere with the rotation of the second sleeve 13. The second sleeve 13 can always rotate under the action of the second motor 15, thereby driving the rotor push rod 11 to move toward or away from the motor rotor, so that the rotor push rod 11 can approach the electronic rotor or contact the motor rotor.

[0034] Through the above technical scheme, since the rotor push rod 11, the first sleeve 12 and the second sleeve 13 all extend along the axial direction of the motor rotor, a first screw-nut pair is formed between the first sleeve 12 and the second sleeve 13, and a second screw-nut pair is formed between the rotor push rod 11 and the second sleeve 13. The first motor 14 and the second motor 15 are respectively connected to the first sleeve 12 and the second sleeve 13 by transmission. By reasonably adjusting the working states of the first motor 14 and the second motor 15, the rotor disassembly device can be put into different working modes, namely the above-mentioned first working mode and the second working mode. In the first working mode and the second working mode, the rotor push rod 11 can contact with the motor rotor, so that the motor rotor can be pushed out of the motor housing through the rotor push rod 11 to realize the disassembly of the motor rotor. The disassembly of the motor rotor is relatively simple and efficient.

[0035] Therefore, the rotor disassembly device provided by the present invention has low operating requirements and can be disassembled without the need for operators with high levels of skills, effectively avoiding the use of tools to knock or push the rotor in related technologies, which can easily damage the motor rotor if the operator has low operating skills.

[0036] In addition, since the pitch of the external thread on the outer surface of the second sleeve 13 is greater than the pitch of the external thread on the outer surface of the rotor push rod 11, the moving speed of the rotor push rod 11 in the first working mode is greater than the moving speed of the rotor push rod 11 in the second working mode. In this way, by switching different working modes of the rotor disassembly device, the disassembly requirements at different stages of the motor rotor disassembly process can be met. For example, when the rotor push rod 11 is far away from the motor rotor, the rotor disassembly device can be adjusted to the first working mode, that is, the second sleeve 13 is driven to move by the first motor 14 and the first sleeve 12, and then the rotor push rod 11 is driven to move. The moving speed of the rotor push rod 11 is faster, and it can move toward the motor rotor faster and contact the motor rotor, thereby reducing the disassembly time of the motor rotor and improving the disassembly efficiency of the motor rotor. When the rotor push rod 11 contacts the motor rotor or is about to contact the motor rotor, the rotor disassembly device can be adjusted to the second working mode. At this time, the second motor 15 and the second sleeve 13 drive the rotor push rod 11 to move, and the rotor push rod 11 can have a lower moving speed and a larger driving force, which makes it easy to align the rotor push rod 11 with the motor rotor on the one hand, and to push the motor rotor out of the motor housing on the other hand, thereby effectively improving the disassembly accuracy of the motor rotor.

[0037] Here, it should be noted that the present disclosure does not limit the specific type of the first motor 14, as long as the first motor 14 can realize the different working modes of the above-mentioned rotor disassembly device.

[0038] As an embodiment of the present disclosure, the above-mentioned first motor 14 can be a non-self-locking motor, that is, when the first motor 14 is not powered on, the output shaft of the first motor 14 can rotate freely. In this way, when the above-mentioned rotor disassembly device is in the second working mode, the first sleeve 12 rotates with the second sleeve 13, and the output shaft of the first motor 14 can rotate synchronously with the first sleeve 12 under the external force provided by the first sleeve 12, thereby avoiding the output shaft of the first motor 14 interfering with the rotation of the first sleeve 12, and then interfering with the rotation of the second sleeve 13.

[0039] As other embodiments of the present disclosure, the first motor 14 can also be a self-locking motor. When the rotor disassembly device is in the second working mode, the first motor 14 can be started so that the rotation speed of the output shaft of the first motor 14 is the same as the rotation speed of the first sleeve 12. In this way, the output shaft of the first motor 14 can be prevented from interfering with the rotation of the first sleeve 12 and the second sleeve 13.

[0040] The present disclosure does not limit the specific structure of the driving mechanism 1. As an implementation method of the present disclosure, Figure 1 , Figure 2 as well as Figure 4As shown, the pushing mechanism 1 also includes a first seat body 16, the first seat body 16 includes a first shell 161, the second sleeve 13 is inserted into the first shell 161, the first sleeve 12 is arranged in the first shell 161, and the two opposite inner walls of the first shell 161 clamp the first sleeve 12 to limit the axial movement of the first sleeve 12 along the second sleeve 13. A guide rod 111 is connected to the rotor push rod 11, and the guide rod 111 is parallel to the rotor push rod 11. A guide hole 162 is formed on the first shell 161 and passes through the first shell 161. The guide rod 111 is movably inserted into the guide hole 162.

[0041] Since the first sleeve 12 is arranged in the first shell 161, and the two relative inner walls of the first shell 161 are clamped on the first sleeve 12, in other words, the first shell 161 can limit the axial movement of the first sleeve 12 along the second sleeve 13. In this way, when the first motor 14 drives the first sleeve 12 to rotate, the first sleeve 12 itself will not move but only rotate. Therefore, the second sleeve 13 can move along the axial direction of the first sleeve 12 under the rotation of the first sleeve 12, and move towards or away from the motor rotor.

[0042] In addition, since a guide hole 162 is formed on the first shell 161 and passes through the first shell 161, the guide rod 111 connected to the rotor push rod 11 can be movably inserted into the guide hole 162, and the hole wall of the guide hole 162 can abut against the outer peripheral surface of the guide rod 111. The guide hole 162 and the guide rod 111 cooperate with each other to limit the rotor push rod 11. The rotor push rod 11 can only move in the direction close to or away from the motor rotor, but cannot rotate. In this way, when the rotor disassembly device is in the second working mode, when the second motor 15 drives the second sleeve 13 to rotate, the rotor push rod 11 cannot rotate. Therefore, the rotor push rod 11 can move in the direction close to or away from the motor rotor under the rotation of the second sleeve 13, thereby realizing the disassembly of the motor rotor.

[0043] Alternatively, if Figure 1 , Figure 2 and Figure 4As shown, the motor rotor disassembly device 100 also includes a base 2, and the pushing mechanism 1 also includes a first seat body 16, the first seat body 16 is movably arranged on the base 2, the first motor 14, the first sleeve 12 and the second motor 15 are all installed on the first seat body 16, and the second sleeve 13 is axially locked and circumferentially rotatably connected to the first seat body 16. Since the first seat body 16 is movably arranged on the base 2, and the second sleeve 13 is circumferentially locked and circumferentially rotatably connected to the first seat body 16, when the motor rotor disassembly device 100 is in the first working mode, the first motor 14 drives the first sleeve 12 to rotate, and the second sleeve 13 moves in the direction close to or away from the motor rotor. Since the second sleeve 13 is axially locked with the first seat body 16, the second sleeve 13 will drive the first seat body 16 to move together, and the relative position between the second sleeve 13 and the first seat body 16 will not change, and the relative position between the second motor 15 and the first seat body 16 will not change, which can prevent the second motor 15 from being disconnected from the second sleeve 13, resulting in the second motor 15 being unable to drive the second sleeve 13 to rotate in the second working mode.

[0044] Alternatively, if Figure 2 and Figure 3 As shown, the pushing mechanism 1 further includes a bearing 17 and a connecting rod 18, wherein the bearing 17 is sleeved on the second sleeve 13, one end of the connecting rod 18 is connected to the bearing 17, and the other end of the connecting rod 18 is connected to the first seat body 16. Since the bearing 17 is sleeved on the second sleeve 13 and is connected to the first seat body 16 through the connecting rod 18, if the second sleeve 13 moves toward or away from the motor rotor under the action of the first motor 14, the second sleeve 13 can pull the first seat body 16 to move through the connecting rod 18, and the first seat body 16 can always move with the second sleeve 13, effectively avoiding the second motor 15 from being separated from the second sleeve 13 when the second sleeve 13 moves, so that the second motor 15 cannot limit the circumferential rotation of the second sleeve 13, or the second motor 15 cannot drive the second sleeve 13 to rotate, resulting in the motor rotor disassembly device 100 being unable to be used normally.

[0045] Alternatively, if Figure 1 and Figure 2 As shown, the first seat body 16 also includes a support seat 163, and the support seat 163 includes a fixed portion 164 and a movable portion 165, and the fixed portion 164 and the movable portion 165 are both used to be set on the base 2, wherein the first shell 161 and the movable portion 165 are adjustably installed on the fixed portion 164 along a horizontal direction perpendicular to the length direction of the base 2, and the movable portion 165 is used to install the second motor 15.

[0046] Since the positions of the first shell 161 and the movable part 165 on the fixed part 164 are adjustable, when disassembling the motor rotor, the operator can adjust the positions of the first shell 161 and the movable part 165 on the fixed part 164 so that the positions of the first sleeve 12, the second sleeve 13, and the rotor push rod 11 can be adjusted, thereby aligning the rotor push rod 11 with the motor rotor to be disassembled. In this way, during the process of disassembling the motor rotor, the rotor push rod 11 will only contact the shaft located in the middle of the motor rotor, and will not contact other parts of the motor rotor (such as the coil of the motor rotor), thereby effectively avoiding the rotor push rod 11 directly contacting other parts of the motor rotor, which may cause the motor rotor to be easily damaged.

[0047] In addition, since the second motor 15 that is transmission-connected to the second sleeve 13 is arranged on the movable part 165, when the position of the first shell 161 on the fixed part 164 changes, the movable part 165 can also move synchronously with the first shell 161. In this way, when the first shell 161 adjusts its installation position on the fixed part 164, the second motor 15 arranged on the movable part 165 can always maintain a transmission connection with the second sleeve 13, which effectively avoids the second motor 15 and the second sleeve 13 being disengaged from each other when the second sleeve 13 moves, so that the second motor 15 cannot limit the circumferential rotation of the second sleeve 13, or the second motor 15 cannot drive the second sleeve 13 to rotate, resulting in the motor rotor disassembly device 100 being unable to be used normally.

[0048] In order to make the first housing 161 and the movable portion 165 movably connected to the fixed portion 164, as shown in FIG. Figure 4 As shown, the motor rotor disassembly device 100 may further include a first adjusting screw 166 and a first nut 167. The first adjusting screw 166 is rotatably inserted into the fixed portion 164, the first nut 167 is sleeved on the first adjusting screw 166, and the first nut 167 is fixedly connected to the first housing 161 and the movable portion 165. In this way, when the position of the first housing 161 on the fixed portion 164 needs to be adjusted, the first adjusting screw 166 is rotated. Since the first nut 167 cannot rotate under the restriction of the first housing 161, the first nut 167 can move along the extension direction of the screw, thereby pushing the first housing 161 and the movable portion 165 to move.

[0049] It should be noted that the present disclosure does not limit the specific transmission connection between the first motor 14 and the first sleeve 12 and the second motor 15 and the second sleeve 13. As an embodiment of the present disclosure, Figure 2 and Figure 3As shown, the pushing mechanism 1 also includes a first driving gear 19, a first driven gear 20, a second driving gear 21 and a second driven gear 22. The first driving gear 19 is connected to the output shaft of the first motor 14, the first driven gear 20 is sleeved on the first sleeve 12, the first driven gear 20 and the first driving gear 19 are meshed with each other, the diameter of the first driven gear 20 is larger than the diameter of the first driving gear 19, the second driving gear 21 is connected to the output shaft of the second motor 15, the second driven gear 22 is sleeved on the second sleeve 13, the second driven gear 22 and the second driving gear 21 are meshed with each other, and the diameter of the second driven gear 22 is larger than the diameter of the second driving gear 21.

[0050] It can be understood that the first driving gear 19 and the second driven gear 22 can form a first gear transmission pair, the second driving gear 21 and the second driven gear 22 can form a second gear transmission pair, the first motor 14 and the second motor 15 are connected to the first sleeve 12 and the second sleeve 13 through the first gear transmission pair and the second gear transmission pair respectively, and the connection between the first motor 14 and the first sleeve 12 and between the second motor 15 and the second sleeve 13 are relatively reliable.

[0051] Furthermore, since the diameter of the first driven gear 20 is larger than the diameter of the first driving gear 19, and the diameter of the second driven gear 22 is larger than the diameter of the second driving gear 21, the first gear transmission pair and the second gear transmission pair can respectively reduce the speed and increase the distance of the first motor 14 and the second motor 15, so that the first motor 14 and the second motor 15 with a relatively small output torque can drive the rotor push rod 11 to move. On the one hand, it effectively avoids the situation that the first motor 14 and the second motor 15 cannot drive the rotor push rod 11 to move, resulting in the inability to disassemble the motor rotor; on the other hand, it is also conducive to saving the cost of the first motor 14 and the second motor 15.

[0052] Optionally, in order to improve the transmission stability of the first driving gear 19, optionally, as Figure 3 As shown, the pushing mechanism 1 further includes a plurality of third driven gears 23, which are arranged at intervals along the circumference of the first driven gear 20, and the plurality of third driven gears 23 are all meshed with the first driven gear 20. In other words, the first driven gear 20 is meshed with a plurality of gears at the same time, and the plurality of gears can reduce the imbalance of the first driven gear 20 during movement, thereby improving the transmission stability of the first driving gear 19.

[0053] As other embodiments of the present disclosure, the motor rotor disassembly device 100 may further include a first pulley, a second pulley, a third pulley, a fourth pulley, a first belt, and a second belt, wherein the first pulley is connected to the output shaft of the first motor 14, the second pulley is sleeved on the first sleeve 12, the first belt is wound around the first pulley and the second pulley, the third pulley is connected to the output shaft of the second motor 15, the fourth pulley is sleeved on the second sleeve 13, and the second belt is wound around the third pulley and the fourth pulley. In other words, the first motor and the second motor both drive the first sleeve 12 and the second sleeve 13 to rotate by belt transmission, thereby driving the rotor push rod 11 to move.

[0054] In order to prevent the motor rotor from falling and being damaged when it is pushed out of the housing, optionally, Figure 1 , Figure 5 and Figure 6 As shown, the motor rotor disassembly device 100 also includes a clamping mechanism 3, which is spaced apart from the pushing mechanism 1 along the axial direction of the motor rotor. The clamping mechanism 3 includes a movable rod 31 and a plurality of clamping portions 32. One end of the movable rod 31 is used to contact the second end of the motor rotor so that it can move along the axial direction of the motor rotor under the push of the motor rotor. The plurality of clamping portions 32 are movably matched with the movable rod 31, and the plurality of clamping portions 32 can move toward a direction close to the motor rotor when the motor rotor pushes the movable rod 31 to move, so as to clamp the motor rotor together.

[0055] Since the clamping mechanism 3 and the pushing mechanism 1 are arranged at intervals along the axial direction of the motor rotor, when the motor rotor is pushed out of the motor housing under the action of the pushing mechanism 1, the motor rotor can be clamped by the clamping mechanism 3, and the motor rotor will not fall directly from the motor housing, effectively avoiding the motor rotor from falling and causing the motor to be easily damaged.

[0056] In addition, since the clamping mechanism 3 includes a movable rod 31 and a plurality of clamping parts 32, and the movable rod 31 can move along the axial direction of the motor rotor under the push of the motor rotor, and the plurality of clamping parts 32 move toward the direction close to the motor rotor, in other words, the motor rotor can be clamped by a plurality of clamping mechanisms 3 at the same time, and the clamping effect of the motor rotor is better and not easy to loosen. Moreover, in the clamping process, no driving structure is required, and the clamping parts 32 can gradually clamp the motor rotor by relying on the movement of the motor rotor itself. The clamping mechanism 3 has a simple structure, low cost, and high reliability.

[0057] Here, it should be noted that, for the embodiment in which the motor rotor disassembly device 100 includes a base 2, the present disclosure does not limit the specific connection relationship between the pushing mechanism 1 and the clamping mechanism 3 and the base 2. As an embodiment of the present disclosure, the pushing mechanism 1 and the clamping mechanism 3 can be movably connected to the base 2. In this way, when the motor rotor is disassembled, the installation position of the pushing mechanism 1 and the clamping mechanism 3 on the base 2 can also be adjusted. By adjusting the installation position of the pushing mechanism 1 and the clamping mechanism 3 on the base 2, the relative position between the pushing mechanism 1 and the clamping mechanism 3 and the motor rotor can be adjusted, so that the pushing mechanism 1 and the clamping mechanism 3 can cooperate with each other, thereby removing the motor rotor.

[0058] As an embodiment of the present disclosure, Figure 5 and Figure 6 As shown, the movable rod 31 includes a rod body 311 and a plurality of inclined rods 312 connected to the rod body 311, the rod body 311 extends along the axial direction of the motor rotor, the clamping mechanism 3 also includes a plurality of guide structures 33, the plurality of inclined rods 312, the plurality of guide structures 33 and the plurality of clamping parts 32 are arranged one by one, each clamping part 32 includes a clamping rod 321, a clamping block 322 fixed at one end of the clamping rod 321 and a sliding block 323 fixed at the other end of the clamping rod 321, the plurality of clamping blocks 322 are used to clamp the motor rotor together, and each clamping rod 321 can be movably passed through the corresponding guide structure 33 and the corresponding inclined rod 312, and a guide groove 331 extending radially along the rod body 311 is formed on one of the guide structure 33 and the clamping rod 321, and a guide block 324 extending radially along the rod body 311 is formed on one of the guide structure 33 and the clamping rod 321, and the guide groove 331 is slidably matched with the guide block 324, and the sliding block 323 is located on the side of the inclined rod 312 away from the clamping block 322, and the sliding block 323 is in contact with the side of the inclined rod 312 away from the clamping block 322.

[0059] When the rod body 311 moves along the axial direction of the motor rotor toward the direction away from the motor housing under the push of the motor rotor, the inclined rod 312 moves with the rod body 311. Due to the limiting effect of the guide block 324 and the guide groove 331, the clamping rod 321 cannot move with the rod body 311 toward the direction away from the motor housing. The sliding block 323 is subjected to the downward force applied by the inclined rod 312, and the clamping rod 321 can only move toward the motor rotor, thereby clamping the motor rotor in multiple clamping blocks 322 to achieve the clamping of the motor rotor. The clamping mechanism 3 has a better clamping effect on the motor rotor.

[0060] As other embodiments of the present disclosure, the clamping mechanism 3 may further include a guide structure 3 and a flexible connector, each clamping portion 32 includes a clamping rod 321 and a clamping block 322 fixed at one end of the clamping rod 321, a plurality of guide structures 33 are arranged in a one-to-one correspondence with a plurality of clamping portions 32, each clamping rod 321 is hinged to the guide structure 33, one end of the flexible connector is connected to a side of the clamping rod 321 close to the clamping block 322, and the other end of the flexible connector is connected to the movable rod 31. In this way, when the movable rod 31 is pushed by the motor rotor and moves in a direction away from the motor rotor, the flexible connector can pull the clamping rod 321 to rotate in a direction close to the motor rotor, so that the clamping block 322 can be clamped on the motor rotor.

[0061] Alternatively, if Figure 5 and Figure 6 As shown, the clamping mechanism 3 also includes a fixed rod 34 and a fixed block 35 installed at one end of the fixed rod 34, the fixed rod 34 extends along the axial direction of the motor rotor, and one end of the rod body 311 away from the clamping mechanism 3 can movably pass through the fixed block 35 and extend into the fixed rod 34, and a plurality of guide long holes 341 extending along the axial direction of the fixed rod 34 are formed on the fixed rod 34, and the movable rod 31 also includes a plurality of guide connecting rods 313 extending along the radial direction of the rod body 311, and the plurality of guide long holes 341, the plurality of guide connecting rods 313 and the plurality of inclined rods 312 are arranged in a one-to-one correspondence, and one end of each guide connecting rod 313 is connected to the rod body 311, and one end of each guide connecting rod 313 passes through the corresponding guide long hole 341 and is connected to the corresponding inclined rod 312, and the plurality of guide structures 33 are installed on the fixed block 35.

[0062] Since a plurality of long guide holes 341 extending along the axial direction of the fixed rod 34 are formed on the fixing rod 34, the rod body 311 is connected to the inclined rod 312 through the guiding connecting rod 313. In this way, when the rod body 311 moves along the axial direction of the motor rotor under the push of the motor rotor, the hole wall of the long guide hole 341 can abut against the side wall of the guiding connecting rod 313. The long guide hole 341 and the guiding connecting rod 313 can jointly limit the rod body 311. The rod body 311 can only move along the axial direction of the motor rotor and cannot rotate circumferentially, which effectively avoids the rotation of the rod body 311 itself, causing the clamping mechanism 3 to rotate. The rotating clamping mechanism 3 is likely to scratch the motor rotor, and even affect the disassembly of the motor rotor.

[0063] In order to improve the clamping effect of the clamping mechanism 3 on the motor rotor, optionally, as Figure 6 As shown, an elastic member 36 is connected between the fixed block 35 and the rod body 311, and the end of the fixed rod 34 away from the movable rod 31 is a closed end, and a one-way valve 37 is arranged on the closed end, wherein the one-way valve 37 is detachably arranged on the closed end, or the one-way valve 37 is a one-way valve with adjustable flow direction.

[0064] Since the end of the fixed rod 34 away from the movable rod 31 is set as a closed end, and a one-way valve 37 is provided on the closed end, when the motor rotor is disassembled, the gas or fluid in the fixed rod 34 can only flow from the fixed rod 34 to the outside through the one-way valve 37, and the connecting rod 18 is adsorbed in the fixed rod 34 due to the action of external pressure, and the connecting rod 18 will not detach outward. In this way, the clamping mechanism 3 can always clamp the motor rotor and is not easy to loosen, and the clamping mechanism 3 has a better clamping effect on the motor rotor.

[0065] In addition, when the motor rotor is disassembled and needs to be taken out from the clamping mechanism 3, the operator can open the one-way valve 37, or adjust the flow direction of the adjustable one-way valve so that the liquid or gas in the external environment can enter the fixed rod 34. At this time, the rod body 311 can move in a direction away from the fixed rod 34, thereby loosening the clamping mechanism 3 and taking the motor rotor out of the clamping mechanism 3. The removal of the motor rotor from the clamping mechanism 3 is also relatively convenient.

[0066] Here, it needs to be explained that the above-mentioned flow-direction adjustable one-way valve means that the gas and / or fluid in the one-way valve 37 can adjust different flow directions according to different usage requirements. For example, when the above-mentioned motor rotor is disassembled, the flow direction of the gas and / or fluid in the one-way valve 37 is from the inside of the fixed rod 34 to the outside of the fixed rod 34. When the motor rotor is disassembled, the flow direction of the gas and / or fluid in the one-way valve 37 can be adjusted from the outside of the fixed rod 34 to the inside of the fixed rod 34.

[0067] Alternatively, if Figure 5 As shown, the clamping mechanism 3 further includes a second seat 39, on which a second shell 38 is disposed, and the fixing rod 34 is passed through the second shell 38. The second shell 38 can fix and support the fixing rod 34, and the fixing rod 34, the movable rod 31 disposed on the fixing rod 34, and the clamping portion 32 are not easy to shake.

[0068] Optionally, the second seat body 39 is movably connected to the base 2. In this way, when the motor rotor is disassembled, the relative position between the clamping mechanism 3 and the motor rotor to be disassembled can be adjusted by adjusting the installation position of the second seat body 39 on the base 2, so that the clamping mechanism 3 can contact the motor rotor, thereby clamping the motor rotor.

[0069] It should be noted that the present disclosure does not limit the specific connection relationship between the second shell 38 and the second seat body 39. As an embodiment of the present disclosure, the second shell 38 is movably disposed on the second seat body 39 along a horizontal direction perpendicular to the length direction of the base 2.

[0070] Since the position of the second shell 38 on the second base body 39 is adjustable, when disassembling the motor rotor, the operator can adjust the position of the second shell 38 on the second base body 39. By adjusting the position of the second shell 38, the adjustment position of the clamping mechanism 3 can be adjusted, so that the clamping mechanism 3 and the motor rotor to be disassembled can be aligned. In this way, during the disassembly of the motor rotor, there will be no deviation between the clamping mechanism 3 and the motor rotor, which effectively avoids the deviation between the clamping mechanism 3 and the motor rotor and the inability of the clamping mechanism 3 to clamp the motor rotor.

[0071] In order to make the second shell 38 movably connected to the second seat body 39, optionally, the above-mentioned motor rotor disassembly device can also include a second adjusting screw and a second nut, the second adjusting screw can be rotatably passed through the second seat body 39, the second nut is sleeved on the second adjusting screw, and the second nut is fixedly connected to the second shell 38. In this way, when it is necessary to adjust the installation position of the second shell 38 on the second seat body 39, the second adjusting screw is rotated. Since the second nut cannot rotate under the restriction of the second shell 38, the second nut can move along the extension direction of the second adjusting screw, thereby pushing the second shell 38 to move.

[0072] To facilitate fixing the motor, optionally, Figure 1 and Figure 7 As shown, the motor rotor disassembly device 100 further includes a fixing mechanism 4, the fixing mechanism 4 includes a lifting structure 41 and a fixing plate 42, the lifting structure 41 is connected to the fixing plate 42 and is used to drive the fixing plate 42 to move up and down, and the fixing plate 42 is used to detachably fix the housing of the motor. In this way, when the motor rotor is disassembled, the operator can fix the motor on the fixing plate 42 of the fixing mechanism 4, and the motor is reliably fixed and not easy to shake.

[0073] In addition, before the motor rotor is disassembled, the height of the fixing plate 42 can be adjusted through the lifting structure 41, thereby adjusting the height of the motor rotor, so that the pushing mechanism 1 and the clamping mechanism 3 can both contact the motor rotor, thereby enabling the pushing mechanism 1 to push the motor rotor and enabling the clamping mechanism 3 to clamp the motor rotor.

[0074] like Figure 1 As shown, the fixing mechanism 4 can be arranged between the pushing mechanism 1 and the clamping mechanism 3. In this way, when the motor rotor is disassembled, the pushing mechanism 1 pushes the motor rotor from one side, and the motor rotor exposed from the other side can be clamped directly by the clamping mechanism 3.

[0075] The present disclosure does not limit the specific structure of the lifting structure 41. As an embodiment of the present disclosure, the lifting structure 41 may include a motor and a scissors-type lifting device. The motor drives the scissors-type lifting device to move, thereby driving the fixed plate 42 to move up and down.

[0076] As another embodiment of the present disclosure, the lifting structure 41 may also be a cylinder, the cylinder body of the cylinder is disposed on the base 2, and the piston rod of the cylinder is connected to the fixed plate 42, thereby driving the fixed plate 42 to move up and down.

[0077] In order to facilitate the adjustment of the position between the motor and the pushing mechanism 1 and the clamping mechanism 3, the fixing mechanism 4 is optionally connected to the base 2 in an adjustable manner. In this way, when the motor rotor is disassembled, the relative position between the motor rotor and the pushing mechanism and the clamping mechanism 3 can be adjusted by adjusting the position of the clamping and fixing mechanism 4, so that the pushing mechanism 1 and the clamping mechanism 3 can cooperate with each other, thereby removing the motor rotor.

[0078] The preferred embodiments of the present disclosure are described in detail above in conjunction with the accompanying drawings; however, the present disclosure is not limited to the specific details in the above embodiments. Within the technical concept of the present disclosure, a variety of simple modifications can be made to the technical solution of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure.

[0079] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present disclosure will not further describe various possible combinations.

[0080] In addition, various embodiments of the present disclosure may be arbitrarily combined, and as long as they do not violate the concept of the present disclosure, they should also be regarded as the contents disclosed by the present disclosure.
