The frameless torque motor has the advantages of low cogging, high torque density, wide torque/current linear range, fast dynamic response and the like, and is widely applied to various robot industries.

When assembling the frameless torque motor, the stator and the self-made shell are fixed and then the rotor is assembled; because the rotor has strong magnetism, when the rotor approaches the stator, the outer surface of the rotor is attracted to the nearest point of the inner bore hole of the stator by magnetic attraction, and the rotor cannot slide downwards along the self-made inner rotating shaft when the matching precision of the rotating shaft and the rotor is high; or friction as the rotor slides down the stator interior can damage the rotor coating and stator bore surface; or the rotor is instantly adsorbed to the bottom of the self-made rotating shaft to form huge impact to damage the rotor and influence the performance of the motor; there may even be magnetic attraction causing injury to the hand, fingers, or body.

Referring to fig. 1 to 3, the present invention provides a torque motor mounting device 100. The torque motor mounting device 100 is used to mount the motor rotor 230 of the torque motor 200 on the outer side of the inner rotating shaft 240. It is understood that the torque motor 200 includes a housing 210, a motor stator 220, a motor rotor 230, and an inner rotating shaft 240, the motor stator 220 is fixedly installed in the housing 210, the inner rotating shaft 240 is rotatably installed in the motor stator 220, and the motor rotor 230 is fixedly installed in the inner rotating shaft 240.

Need be equipped with the crossbeam of multiple size like this in order to satisfy the assembly needs of different specification motors, increase cost still can reduce assembly efficiency, be not convenient for use when changing the crossbeam moreover.

Therefore, the utility model provides a novel torque motor mounting device 100, the torque motor mounting device 100 can be suitable for mounting torque motors 200 with different specifications, certain accessories of the torque motor mounting device 100 do not need to be replaced, the mounting cost of the torque motor mounting device 100 for mounting the torque motors 200 with different specifications can be reduced, the mounting efficiency is improved, and the torque motor mounting device is convenient for operators to use. The specific structure of the torque motor mounting device 100 will be described in detail below.

Referring to fig. 1 to 3, in an embodiment, the torque motor mounting device 100 includes a supporting mechanism 110, an adjusting mechanism 120, and an actuator 130. The bottom of the supporting mechanism 110 is supported by the inner rotating shaft 240. The adjustment mechanism 120 is movably disposed to the support mechanism 110. The actuator 130 is rotatably connected to the adjusting mechanism 120, the actuator 130 has at least two fixing ends 1321, and the actuator 130 is fixed to the motor rotor 230 through at least two fixing ends 1321. The adjusting mechanism 120 can drive the actuating mechanism 130 to drive at least two of the fixing ends 1321 to approach to or separate from each other, and the adjusting mechanism 120 can drive the actuating mechanism 130 to drive the motor rotor 230 to ascend or descend through the fixing ends 1321.

The supporting mechanism 110 is a supporting structure of the torque motor mounting device 100, and supports each component of the torque motor mounting device 100 through the supporting mechanism 110, so that the torque motor mounting device 100 reliably supports the motor rotor 230, and the position of the motor rotor 230 is prevented from moving. Specifically, the bottom of the supporting mechanism 110 is supported at the end of the inner rotating shaft 240, and the top of the supporting mechanism 110 is capable of being operated by an operator, so as to facilitate the installation and removal of the control motor rotor 230.

The adjustment mechanism 120 is movably disposed on the support mechanism 110, and the adjustment mechanism 120 is capable of moving relative to the support mechanism 110 and being fixed relative to the support mechanism 110. When the adjusting mechanism 120 moves, the adjusting mechanism 120 can move up and down relative to the supporting mechanism 110, and when the adjusting mechanism 120 stops moving, the adjusting mechanism 120 is stationary relative to the supporting mechanism 110 and will not fall off the supporting mechanism 110.

The end of the adjusting mechanism 120 is rotatably connected to the actuator 130, and the end of the actuator 130 away from the adjusting mechanism 120 has at least two fixed ends 1321. The adjusting mechanism 120 is a driving part of the actuator 130, and is used for driving the actuator 130 to move so as to adjust the distance between the ends of the actuator 130. It is understood that the end of the actuator 130 herein refers to the end of the actuator 130 distal from the adjustment mechanism 120. The adjusting mechanism 120 can adjust the distance between the ends of the actuator 130 to accommodate the installation of different motor rotors 230.

Further, the end of the actuator 130 has at least two fixing ends 1321, and when the actuator 130 is driven by the adjusting mechanism 120 to move, the adjusting mechanism 120 can adjust the distance between the at least two fixing ends 1321 to adapt to the installation of the motor rotors 230 with different specifications. Also, at least two fixing ends 1321 are fixed to the end of the motor rotor 230, respectively, and the fixing ends 1321 are spaced apart at the end of the motor rotor 230.

When the adjusting mechanism 120 moves relative to the supporting mechanism 110, the adjusting mechanism 120 can drive the actuating mechanism 130 to move, and then the actuating mechanism 130 can make the at least two fixing ends 1321 approach or separate from each other when moving, so as to achieve the purpose of adjusting the distance between the at least two fixing ends 1321. Due to the fact that the torque motors 200 with different specifications and the diameter sizes of the motor rotors 230 are different, the adjusting mechanism 120 drives the actuating mechanism 130 to adjust the distance between the at least two fixing ends 1321, the at least two fixing ends 1321 can adapt to the sizes of the motor rotors 230 with different specifications, the fixing ends 1321 can be accurately fixed to the motor rotors 230, and the motor rotors 230 can be accurately mounted on the inner rotating shaft 240 in the later period.

When the adjusting mechanism 120 moves relative to the supporting mechanism 110, the actuator 130 can be driven to synchronously ascend or descend relative to the supporting mechanism 110. When the adjusting mechanism 120 descends relative to the supporting mechanism 110, the adjusting mechanism 120 can drive the actuator 130 to descend, and then the actuator 130 can drive the motor rotor 230 to descend, so that the motor rotor 230 gradually moves into the motor stator 220 and is mounted on the inner rotating shaft 240. When the adjusting mechanism 120 is lifted relative to the supporting mechanism 110, the adjusting mechanism 120 can drive the actuator 130 to lift, and then the actuator 130 can drive the motor rotor 230 to lift, so that the motor rotor 230 gradually disengages from the inner rotating shaft 240 and moves out of the motor stator 220.

It is understood that the motor stator 220 generates a large magnetic attraction force to the motor rotor 230 during the assembly and disassembly of the motor rotor 230. Because the bottom of the supporting mechanism 110 is already supported on the inner rotating shaft 240, and the inner rotating shaft 240 is already fixed to the motor stator 220 through the bearing, at this time, the position of the motor rotor 230 can be limited through the cooperation of the supporting mechanism 110, the adjusting mechanism 120 and the actuating mechanism 130, so that the motor rotor 230 is accurately located at the outer side of the inner rotating shaft 240 and cannot be adsorbed by the motor stator 220, the motor rotor 230 can be accurately mounted on the inner rotating shaft 240, and the motor rotor 230 can be conveniently dismounted from the inner rotating shaft 240.

Referring to fig. 1 to 3, when the torque motor mounting device 100 of the present invention is used, the diameter of the motor stator 220 and the diameter of the motor rotor 230 are determined, and then the distance between the at least two fixing ends 1321 is adjusted according to the diameter of the motor rotor 230.

Specifically, when the diameter of the motor rotor 230 becomes larger, the adjusting mechanism 120 is adjusted downward, the adjusting mechanism 120 moves downward along the supporting mechanism 110, and then the actuating mechanism 130 can be opened, so as to increase the distance between at least two fixing ends 1321, and thus, the fixing ends 1321 can be accurately installed in the motor rotor 230. The adjustment mechanism 120 then drives the actuator 130 to move downward relative to the support mechanism 110, so that the actuator 130 can drive the motor rotor 230 to move downward to mount the motor rotor 230 on the inner rotating shaft 240.

When the diameter of the motor rotor 230 is smaller, the adjusting mechanism 120 is adjusted upward, that is, the adjusting mechanism 120 moves upward relative to the supporting mechanism 110, so that the adjusting mechanism 120 can drive the actuator 130 to contract, and the distance between at least two fixing ends 1321 is reduced, so that the fixing ends 1321 can be accurately installed in the motor rotor 230. The adjustment mechanism 120 then drives the actuator 130 to move downward relative to the support mechanism 110, so that the actuator 130 can drive the motor rotor 230 to move downward to mount the motor rotor 230 on the inner rotating shaft 240.

It should be noted that the disassembling process of the motor rotor 230 is substantially the same as the assembling process of the motor rotor 230, except that when the motor rotor 230 is disassembled, the adjusting mechanism 120 drives the actuating mechanism 130 to move upward, so that the motor rotor 230 is moved out of the inner rotating shaft 240, and other contents are not described herein again.

The torque motor mounting device 100 in the above embodiment moves relative to the supporting mechanism 110 through the adjusting mechanism 120 to drive the actuating mechanism 130 to drive the at least two fixed ends 1321 to move, so as to adapt to mounting of the torque motors 200 with different specifications, effectively solve the problems of high cost and low efficiency caused by the fact that the beam needs to be replaced to adapt to the mounting of the motors with different specifications, avoid replacing parts in the torque motor mounting device 100, reduce the mounting cost, improve the mounting efficiency, and facilitate the assembly of operators. Meanwhile, the adjusting mechanism 120 can also drive the actuator 130 to drive the motor rotor 230 to ascend or descend, so that the motor rotor 230 is mounted on the inner rotating shaft 240 or dismounted from the inner rotating shaft 240, thereby facilitating the mounting and dismounting of the motor rotor 230.

Referring to fig. 1 to 3, in an embodiment, the adjusting mechanism 120 includes a lifting adjusting assembly 122 and a spacing adjusting assembly 121, the lifting adjusting assembly 122 is movably disposed on the supporting mechanism 110, the spacing adjusting assembly 121 is movably disposed on the lifting adjusting assembly 122, the spacing adjusting assembly 121 is rotatably connected to the actuator 130, the spacing adjusting assembly 121 is capable of adjusting a spacing between at least two of the fixed ends 1321, and the lifting adjusting assembly 122 is capable of driving the spacing adjusting assembly 121 to drive the motor rotor 230 to ascend or descend.

The elevation adjustment assembly 122 is disposed outside the support mechanism 110 and is movable relative to the support mechanism 110. The spacing adjustment assembly 121 is disposed outside the elevation adjustment assembly 122 and is movable relative to the elevation adjustment assembly 122. When the lifting adjusting component 122 moves relative to the supporting mechanism 110, the lifting adjusting component 122 can drive the spacing adjusting component 121 to move synchronously; the lift adjustment assembly 122 remains stationary as the spacing adjustment assembly 121 moves relative to the lift adjustment assembly 122. That is to say, the lifting adjusting assembly 122 can drive the spacing adjusting assembly 121 to move synchronously, and the spacing adjusting assembly 121 cannot drive the lifting adjusting assembly 122 to move.

When the lifting adjusting assembly 122 moves, the lifting adjusting assembly 122 can move up and down relative to the supporting mechanism 110, and when the lifting adjusting assembly 122 stops moving, the lifting adjusting assembly 122 is stationary relative to the supporting mechanism 110 and cannot slide off the supporting mechanism 110. When the spacing adjustment assembly 121 moves, the spacing adjustment assembly 121 can move up and down relative to the lifting adjustment assembly 122, and when the spacing adjustment assembly 121 stops moving, the spacing adjustment assembly 121 is static relative to the lifting adjustment assembly 122 and cannot fall off from the lifting adjustment assembly 122.

The lifting adjusting component 122 is used for realizing the installation and the disassembly of the motor rotor 230, and the spacing adjusting component 121 is used for adjusting the spacing between at least two fixed ends 1321 in the actuating mechanism 130 so as to adapt to the installation of the motor rotors 230 with different specifications. The end of the spacing adjustment assembly 121 is rotatably connected to the actuator 130, and the spacing adjustment assembly 121 is a driving part of the actuator 130, and is used for driving the actuator 130 to move so as to adjust the spacing between the at least two fixed ends 1321.

When the spacing adjustment assembly 121 moves relative to the lifting adjustment assembly 122, the spacing adjustment assembly 121 can drive the actuator 130 to move, and then the actuator 130 can make the two fixed ends 1321 close to each other or keep away from each other when moving, so as to adjust the spacing between the at least two fixed ends 1321. Due to the fact that the torque motors 200 with different specifications have different diameters and sizes of the motor rotor 230, the distance adjusting assembly 121 drives the actuating mechanism 130 to adjust the distance between the at least two fixing ends 1321, the at least two fixing ends 1321 can adapt to the sizes of the motor rotors 230 with different specifications, and the fixing ends 1321 can be accurately fixed to the motor rotors 230.

After the fixed end 1321 is installed on the motor rotor 230, the lifting adjusting assembly 122 is driven to move downward relative to the supporting mechanism 110, at this time, the lifting adjusting assembly 122 can drive the spacing adjusting assembly 121 and the executing mechanism 130 to descend synchronously, and when the executing mechanism 130 descends, the executing mechanism 130 can drive the motor rotor 230 to descend synchronously, so that the motor rotor 230 gradually moves into the motor stator 220 and is installed on the inner rotating shaft 240.

When the torque motor 200 is installed by using the torque motor installation device 100 of the present embodiment, the distance between at least two fixed ends 1321 of the actuator 130 is adjusted by the distance adjustment assembly 121, so as to adapt to the installation of the motor rotors 230 with different specifications. The fixed end 1321 is mounted on the motor rotor 230, and then the elevation adjustment assembly 122 drives the spacing adjustment assembly 121 and the actuator 130 to move synchronously, so that the actuator 130 drives the motor rotor 230 to be mounted on the inner rotating shaft 240 or move out of the inner rotating shaft 240.

Referring to fig. 1 to fig. 3, in an embodiment, the distance adjusting assembly 121 includes a first adjusting member 1211 and at least two transmission members 1212, the first adjusting member 1211 is rotatably disposed on the elevation adjusting assembly 122, at least two of the transmission members 1212 are symmetrically disposed on the first adjusting member 1211 and respectively connected to the actuating mechanism 130, at least two of the transmission members 1212 are rotatably disposed on the elevation adjusting assembly 122, and when the first adjusting member 1211 moves, the actuating mechanism 130 can be driven by the transmission members 1212 to drive at least two of the fixing ends 1321 to approach or move away from each other.

The first adjusting member 1211 is rotatably disposed on the elevation adjustment assembly 122 and can move up and down along the elevation adjustment assembly 122, and when the first adjusting member 1211 is at rest, the first adjusting member 1211 can be fixed on the outer side of the elevation adjustment assembly 122. The first adjusting member 1211 is a power source of the distance adjusting assembly 121, and the movement of the first adjusting member 1211 is adjusted to control the ascending and descending movement of the distance adjusting assembly 121 relative to the ascending and descending adjusting assembly 122.

At least two transmission members 1212 are symmetrically disposed on the peripheral side of the first adjusting member 1211, each transmission member 1212 is rotatably connected to the first adjusting member 1211, and each transmission member 1212 is also rotatably connected to the actuator 130 and the lifting/lowering adjusting assembly 122. When the first adjusting member 1211 moves up and down relative to the lifting adjustment assembly 122, the first adjusting member 1211 can drive each transmission member 1212 to move, and further each transmission member 1212 can be supported by the lifting adjustment assembly 122 to drive the actuator 130 to move relative to the lifting adjustment assembly 122, so that at least two fixing ends 1321 are close to or away from each other, thereby adjusting the distance between the fixing ends 1321.

After the transmission component 1212 is rotatably connected to the lifting adjustment assembly 122, the lifting adjustment assembly 122 can provide support for the movement of the transmission component 1212, so that the transmission component 1212 can move according to a preset track, and the influence on the movement of the actuator 130 due to the irregular movement of the transmission component 1212 is avoided.

At least two transmission components 1212 are symmetrically disposed at the rear of the circumferential side of the first adjusting component 1211, and the at least two transmission components 1212 can implement symmetric transmission of motion, so as to enable the motion track of the actuator 130 to be accurate, enable the motion distances of the fixed ends 1321 to be consistent, and ensure that the stress of the fixed ends 1321 is balanced, thereby ensuring that the torque motor mounting device 100 can be reliably mounted on the motor rotor 230.

Referring to fig. 1 to 3, in an embodiment, the driving unit 1212 includes a first driving rod 12121 and a second driving rod 12122, wherein one end of the first driving rod 12121 is rotatably connected to the first adjusting unit 1211, the other end of the first driving rod 12121 is rotatably connected to a middle region of the second driving rod 12122, one end of the second driving rod 12122 is rotatably connected to the ascent/descent adjusting assembly 122, and the other end of the second driving rod 12122 is rotatably connected to the actuator 130.

The first transmission rod 12121 cooperates with the second transmission rod 12122 to drive the movement of the actuator 130. After one end of the second driving rod 12122 is rotatably connected to the elevation adjustment assembly 122, the elevation adjustment assembly 122 can provide a support for the second driving rod 12122 such that the second driving rod 12122 can rotate about its connection with the elevation adjustment assembly 122. After the first driving rod 12121 is rotatably coupled to the first adjustment member 1211, the first driving rod 12121 can rotate about the first adjustment member 1211.

When the first adjusting member 1211 moves, the first adjusting member 1211 can drive the first transmission rod 12121 to rotate relative to the first adjusting member 1211. When the first transmission rod 12121 rotates, the first transmission rod 12121 can drive the second transmission rod 12122 to rotate relative to the lifting adjustment assembly 122, and when the second transmission rod 12122 rotates, the other end of the second transmission rod 12122 can drive the actuator 130 to move in a rotatable manner, so that the actuator 130 can drive at least two fixed ends 1321 thereof to approach or move away from each other.

Alternatively, the rotation connection here means that two adjacent connecting parts are connected through a rotating shaft. Of course, in other embodiments of the present invention, the rotational connection may also be a hinge or other connection that enables rotation.

Referring to fig. 1 to 3, in an embodiment, the actuator 130 includes at least two actuator members 131 and at least two fixing members 132, one end of each actuator member 131 is connected to the second transmission rod 12122, the other end of each actuator member 131 is rotatably connected to one fixing member 132, and the fixing member 132 has a fixing end 1321 for connecting to the motor rotor 230.

The number of the executing components 131 is equal to that of the transmission components 1212. That is, each transmission unit 1212 corresponds to one actuator 131, and drives each actuator 131 to expand or contract, so as to adjust the distance between the fixed ends 1321, so that the torque motor mounting apparatus 100 can be suitable for mounting motor rotors 230 of different specifications. The end of each actuating element 131 remote from the transmission element 1212 has a fastening element 132, the fastening element 132 has a fastening end 1321, and the fastening end 1321 can be fastened in the motor rotor 230, so that the actuating element 130 is fixedly connected to the motor rotor 230.

The connection between one executing unit 131 and one transmission unit 1212 is taken as an example for description, and the connection between the other executing units 131 and the transmission unit 1212 is substantially the same, and thus, the description thereof is omitted. One end of the actuator 131 is rotatably connected to one end of the second transmission rod 12122 away from the lifting adjustment assembly 122, the other end of the actuator 131 is rotatably connected to the fixing member 132, the end of the fixing member 132 away from the actuator 131 is a fixed end 1321, and the fixing member 132 is fixed to the motor rotor 230 by the fixed end 1321.

When the first adjusting member 1211 moves relative to the elevation adjustment assembly 122, the first adjusting member 1211 can drive the first transmission rod 12121 to move, and then the first transmission rod 12121 drives the second transmission rod 12122 to move, so that the second transmission rod 12122 drives the actuating member 131 to move toward a direction close to or away from the elevation adjustment assembly 122, and when the actuating member 131 moves, the actuating member 132 thereon can be driven to move, so as to adjust a distance between at least two fixed ends 1321, thereby adapting to the installation of the motor rotors 230 with different specifications.

Optionally, the fixing end 1321 is a threaded section, and the fixing end 1321 is fixed to the motor rotor 230 by a threaded connection. Of course, in other embodiments of the present invention, the fixing end 1321 may also have other structures capable of being connected with the motor rotor 230. Optionally, the actuating member 131 is a rigid actuating rod; of course, in other embodiments of the present invention, the actuating member 131 may also be a flexible article such as a steel cable.

Optionally, the actuator 130 further comprises a threaded pin 133, and the rotatable connection between the actuator 131 and the fixed member 132 is realized through the threaded pin 133. Of course, in other embodiments of the present invention, the threaded pin 133 may be replaced by other components that enable rotatable connection.

Alternatively, the fixing member 132 is a U-shaped connection structure, such that the fixing member 132 can be sleeved on the end of the actuating member 131 and rotatably connected by the threaded pin 133, and the fixing end 1321 is disposed at the bottom of the fixing member 132 and extends out of the fixing member 132 to be connected to the motor rotor 230.

Illustratively, the number of the actuating members 131 is two, and correspondingly, the number of the transmission members 1212 and the number of the fixing members 132 are both two, and the two actuating members 131 are symmetrically arranged and connected to the first adjusting member 1211 through the corresponding transmission members 1212. Of course, in other embodiments of the present invention, the number of the actuating units 131 may also be three, four, etc., the number of the transmission units 1212 and the fixing units 132 corresponds to the number of the actuating units 131, and the plurality of actuating units 131 are symmetrically disposed. In the present invention, the number of the execution units 131 is two for illustration, and when the number of the execution units 131 is more, the structure and the operation principle thereof are substantially the same as those of the two execution units 131, which is not described herein again.

Two transmission members 1212 are symmetrically disposed on both sides of the first adjustment member 1211, wherein in each transmission member 1212, one end of the second transmission rod 12122 is rotatably connected to the lifting adjustment assembly 122, the other end of the second transmission rod 12122 is rotatably connected to the actuator 131, a middle region of the second transmission rod 12122 is rotatably connected to one end of the first transmission rod 12121, and an end of the actuator 131 is rotatably connected to the fixing member 132.

When the torque motor mounting device 100 is used, the diameter of the motor stator 220 and the diameter of the motor rotor 230 are determined, and then the distance between the at least two fixed ends 1321 is adjusted according to the diameter of the motor rotor 230. When the diameter of the motor rotor 230 becomes larger, the first adjusting member 1211 is adjusted downward such that the first adjusting member 1211 moves downward relative to the ascent and descent adjusting assembly 122, and a distance between the first adjusting member 1211 and the second driving rod 12122 at the end of the ascent and descent adjusting assembly 122 is reduced. At this time, the first adjusting member 1211 can drive the first driving rod 12121 to move away from the lift adjustment assembly 122, and the first driving rod 12121 can drive the second driving rod 12122 to move away from the lift adjustment assembly 122, so that the second driving rod 12122 can drive the corresponding actuating member 131 to move away from the lift adjustment assembly 122, so that the two actuating members 131 are expanded, and the distance between the two fixing members 132 is increased, so that the fixing end 1321 of the fixing member 132 can be accurately installed in the motor rotor 230.

When the diameter of the motor rotor 230 is reduced, the first adjusting member 1211 is adjusted upward such that the first adjusting member 1211 moves upward relative to the ascent and descent adjusting assembly 122, increasing a distance between the first adjusting member 1211 and the second driving rod 12122 at an end of the ascent and descent adjusting assembly 122. At this time, the first adjusting member 1211 can drive the first driving rod 12121 to move toward the direction approaching the ascent and descent adjusting assembly 122, and the first driving rod 12121 can drive the second driving rod 12122 to move toward the direction approaching the ascent and descent adjusting assembly 122, so that the second driving rod 12122 can drive the corresponding actuating member 131 to move toward the direction approaching the ascent and descent adjusting assembly 122 to contract the two actuating members 131 and reduce the distance between the two fixing members 132, and thus the fixed end 1321 of the fixing member 132 can be accurately installed in the motor rotor 230.

In this way, the torque motor mounting device 100 can adapt to motor rotors 230 with different specifications, so that the fixed end 1321 can be mounted in the motor rotor 230. Subsequently, the lifting adjusting assembly 122 moves downward relative to the supporting mechanism 110, at this time, the lifting adjusting assembly 122 can drive the spacing adjusting assembly 121 and the actuating mechanism 130 to descend synchronously, and when the actuating mechanism 130 descends, the actuating mechanism 130 can drive the motor rotor 230 to descend synchronously, so that the motor rotor 230 gradually moves into the motor stator 220 and is installed on the inner rotating shaft 240. Therefore, the motor rotor 230 is assembled, and the motor rotor 230 is accurately installed.

Referring to fig. 1 to 3, in an embodiment, the lifting adjusting assembly 122 includes a lifting rod 1221 and a second adjusting member 1222, the lifting rod 1221 is movably sleeved on the supporting mechanism 110, the second adjusting member 1222 is rotatably sleeved on the supporting mechanism 110 and is located below the lifting rod 1221, the first adjusting member 1211 is rotatably disposed on the lifting rod 1221, and the transmission member 1212 is rotatably disposed on the second adjusting member 1222.

The lifting rod 1221 is a hollow rod-shaped structure, and the lifting rod 1221 is sleeved outside the supporting mechanism 110 and can move along the supporting mechanism 110. That is, the lifting rod 1221 has a hollow inner diameter larger than the outer diameter of the supporting mechanism 110, and the lifting rod 1221 can freely rotate and/or move relative to the supporting mechanism 110. The first adjusting member 1211 is rotatably mounted on the housing of the lifting rod 1221, and when the lifting rod 1221 rotates relative to the supporting mechanism 110, the rotating motion of the lifting rod 1221 is engaged with the first adjusting member 1211 to enable the first adjusting member 1211 to perform a lifting motion, so as to adjust the distance between the first adjusting member 1211 and the second adjusting member 1222, and further adjust the distance between the two fixed ends 1321, so as to adapt to the mounting of the motor rotors 230 with different specifications.

The second adjusting member 1222 is disposed below the lifting rod 1221, the outer circumference of the second adjusting member 1222 is rotatably coupled to one end of the second transmission rod 12122 of the transmission member 1212, and the second adjusting member 1222 is rotatably disposed on the support mechanism 110. When the supporting mechanism 110 rotates, the rotation of the supporting mechanism 110 is matched with the second adjusting member 1222 through rotation, so that the second adjusting member 1222 drives the lifting rod 1221 to move up and down, and further drives at least two fixing ends 1321 of the actuator 120 to move up and down through the transmission member 1212, so as to drive the motor rotor 230 to be installed on the inner rotating shaft 240 or removed from the inner rotating shaft 240.

In one embodiment, the first adjusting member 1211 has a first internal thread, the lifting rod 1221 has a first external thread, and the first adjusting member 1211 is connected to the lifting rod 1221 by a screw-fit connection. After the first adjusting member 1211 is sleeved on the lifting rod 1221, the first internal thread and the second external thread are screwed together.

The first adjusting member 1211 can be raised or lowered with respect to the lifting rod 1221 by engagement of the first internal thread with the first external thread. Specifically, when the lifting rod 1221 is rotated, the rotation of the lifting rod 1221 can make the first adjusting member 1211 perform a lifting motion through the matching of the first internal thread and the second internal thread, so as to adjust the distance between the ends of the actuating member 131. Furthermore, when the first adjusting member 1211 is stationary, the first internal thread and the first external thread are self-locked, so that the first adjusting member 1211 is securely fixed to the lifting rod 1221. Thus, the first adjusting member 1211 is movably disposed on the lifting rod 1221 by means of screw-fitting.

Referring to fig. 1 to 3, in an embodiment, the supporting mechanism 110 includes a supporting rod 111, a base 112 and a supporting head 113, the supporting rod 111 connects the base 112 and the supporting head 113, the base 112 is supported on the inner rotating shaft 240, and the lifting rod 1221 is sleeved outside the supporting rod 111.

The supporting rod 111 plays a supporting role, the outer wall of the supporting rod 111 is sleeved with the lifting rod 1221, and the lifting adjusting component 122 and the interval adjusting component 121 are supported through the supporting rod 111. The bottom of the supporting rod 111 is provided with a base 112, and the base 112 increases the contact area between the supporting rod 111 and the inner rotating shaft 240, thereby ensuring that the supporting mechanism 110 can be reliably supported on the inner rotating shaft 240. The top of the support bar 111 has a support head 113. The supporting head 113 is an operation part of an operator, and the operator controls the supporting rod 111 to rotate through the supporting head 113, so as to drive the lifting rod 1221 to drive the distance adjusting assembly 121 and the executing mechanism 130 to lift synchronously, thereby realizing the lifting control of the motor rotor 230.

Optionally, the top of the supporting head 113 is hexagonal, and the supporting head 113 is clamped by a monkey wrench to complete the rotation of the supporting rod 111. Of course, the support head 113 may have an operation hole, and the support rod 111 may be rotated by inserting a screwdriver or the like into the operation hole.

In one embodiment, the lifting rod 1221 can abut against the second adjusting member 1222. That is, the lifting rod 1221 and the second adjusting member 1222 are not connected to each other. At this time, the lifting rod 1221 can always maintain contact with the second adjustment member 1222 by gravity. When the supporting mechanism 110 rotates, the second adjusting component 1222 can move up and down, and when the second adjusting component 1222 moves up and down, the lifting rod 1221 can be driven to move up and down synchronously, so that the transmission component 1212 drives the executing mechanism 130 to move up and down, thereby realizing the lifting control of the motor rotor 230.

Optionally, the outer diameter of the lifting rod 1221 is larger than the inner diameter of the second adjustment member 1222. Thus, the end surface of the lifting rod 1221 can be ensured to abut against the end surface of the second adjusting member 1222, and the lifting rod 1221 is prevented from sliding through the inner hole of the second adjusting member 1222.

In one embodiment, the support rod 111 has a second external thread; the second adjustment member 1222 has a second internal thread. The second adjusting member 1222 is coupled to the supporting rod 111 by screw-fitting.

The second adjusting member 1222 can be raised or lowered with respect to the support rod 111 by the engagement of the second internal threads with the second external threads. Thus, when the supporting rod 111 is rotated, the supporting rod 111 makes the second adjusting component 1222 perform lifting movement through the matching of the second internal thread and the second external thread, and the second adjusting component 1222 can drive the lifting rod 1221, the distance adjusting component 121 and the executing mechanism 130 to synchronously lift when lifting, so as to realize the lifting control of the motor rotor 230. Furthermore, when the second adjusting member 1222 is stationary, the second internal thread and the second external thread can be self-locked, so that the second adjusting member 1222 and the lifting rod 1221 can be reliably fixed to the supporting rod 111. In this way, the second adjusting member 1222 and the lifting rod 1221 can be movably disposed on the supporting rod 111 by means of screw-fitting.

In one embodiment, the lifting rod 1221 is axially fixed to the second adjusting member 1222 and can rotate relative to the second adjusting member 1222. That is, the lifting rod 1221 and the second adjusting member 1222 are connected, and the lifting rod 1221 and the second adjusting member 1222 are fixed in the axial direction and rotatably connected in the circumferential direction to realize relative rotation around the axial direction. For example, the connection means that is axially fixed and relatively rotatable around the axial direction may be a bearing or the like.

Thus, when the supporting mechanism 110 rotates, the second adjusting member 1222 drives the supporting rod 1221 to move up and down synchronously. When the elevation rod 1221 is rotated, the second adjusting member 1222 is kept stationary, and the first adjusting member 1211 is elevated and lowered to adjust the distance between the first adjusting member 1211 and the second adjusting member 1222.

In one embodiment, the support rod 111 has a second external thread; the lifting rod 1221 or the second adjusting member 1222 has a second internal thread. The lifting rod 1221 is connected with the supporting rod 111 through thread matching; alternatively, the second adjusting member 1222 is coupled to the supporting rod 111 by screw-fitting.

The second adjusting member 1222 and the lifting rod 1221 can be lifted or lowered relative to the supporting rod 111 by the matching of the second internal thread and the second external thread, so as to drive the lifting rod 1221 to drive the spacing adjusting assembly 121 and the executing mechanism 130 to lift synchronously, thereby realizing the lifting control of the motor rotor 230. After the second adjusting member 1222 and the lifting rod 1221 are stationary, the second internal thread and the second external thread can be self-locked, so that the second adjusting member 1222 and the lifting rod 1221 can be reliably fixed to the supporting rod 111. In this way, the second adjusting member 1222 and the lifting rod 1221 can be movably disposed on the supporting rod 111 by means of screw-fitting.

Illustratively, the second adjusting member 1222 may have a second internal thread, and the second adjusting member 1222 may move relative to the support rod 111 by the engagement of the second internal thread with the second external thread. Of course, the lifting rod 1221 may have a second internal thread, and the lifting rod 1221 moves relative to the supporting rod 111 through the engagement of the second internal thread and the second external thread.

In one embodiment, the first adjusting member 1211 is a wing nut; alternatively, the first adjusting member 1211 includes a first fixing portion and a second fixing portion, the first fixing portion and the second fixing portion are installed on the lifting rod 1221 in an involutory manner, and the transmission member 1212 is rotatably connected to a connection portion of the first fixing portion and the second fixing portion. The first adjustment member 1211 has the same or different structure as the second adjustment member 1222.

It should be noted that the structure of the first adjusting member 1211 is not limited in principle, as long as the first transmission rod 12121 can be connected thereto, and the description thereof is omitted here. In this embodiment, the first adjusting member 1211 and the second adjusting member 1222 have the same structure, which facilitates adjustment. Of course, in other embodiments of the present invention, the first adjustment member 1211 and the second adjustment member 1222 may have different structures.

Referring to fig. 1 to 3, in use, the torque motor mounting device 100 of the present invention first determines the diameter size of the motor stator 220 and the motor rotor 230, and then adjusts the distance between the at least two fixing ends 1321 according to the diameter size of the motor rotor 230. The distance between the ends of the actuating members 131 is first adjusted by the distance adjusting assembly 121. The first adjusting member 1211 is adjusted, the first adjusting member 1211 is screwed by the matching of the first internal thread and the second internal thread, so that the first adjusting member 1211 can ascend or descend relative to the lifting rod 1221, and when the first adjusting member 1211 moves, the transmission member 1212 can be driven to drive the two actuating rods to move, so as to adjust the distance between the two actuating members 131, and adapt to the motor rotors 230 with different specifications.

Then, the fixing ends 1321 of the both side fixing members 132 are screwed into the female screw holes of the motor rotor 230, and the fixing members 132 are rotatably coupled to the end portions of the actuating members 131. The entire torque motor mounting apparatus 100 is placed on the inner spindle 240 via the base 112.

The second adjusting member 1222 is fixed according to the distance that the motor rotor 230 needs to be installed to be lowered in the current state, and the rotary support rod 111 can dynamically adjust the position of the second adjusting member 1222. Specifically, rotating support rod 111, can making lifter 1221 descend for support rod 111 through the cooperation of second internal thread and second external thread, can drive lifter 1221 when lifter 1221 descends and drive interval adjustment assembly 121 and actuating mechanism 130 and descend in step, like this, executive component 131 can drive motor rotor 230 and descend slowly to the installation tip of pivot 240 in making motor rotor 230 install, accomplish effective installation.

After the above operations are completed, the motor rotor 230 may be mounted on the inner rotating shaft 240, thereby completing the effective mounting of the torque motor 200.
