Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic drawings, which illustrate the basic structure of the present invention in a schematic manner, and thus show only the components related to the present invention.
As shown in fig. 1 to 5, the utility model provides a 4 loading and unloading mechanisms of rotor subassembly for servo motor, include: stator assembly 1, positioning part 2 and driving part 3. The stator assembly 1 is internally adapted to mount a rotor assembly 4. The positioning portion 2 is adapted to position the driving portion 3 and guide the sliding direction of the rotor assembly 4. The drive section 3 is adapted to drive the rotor assembly 4 into the stator assembly 1. With respect to the above components, a detailed description is given below.
The positioning part 2 is detachably arranged on one side, far away from the notch, of the stator shell 11, and the positioning part 2 is arranged coaxially with the stator shell 11. One end of the positioning part 2 extends axially along the stator housing 11 so that the rotor assembly 4 can be sleeved on the positioning part 2. And the rotor assembly 4 is able to slide axially along the locating portion 2. When the positioning part 2 is installed, the positioning part 2 is axially inserted into the inner side of the limit bearing 12 until the end part of the positioning part 2 is abutted against one side of the limit bearing 12, at the moment, the positioning part 2 is attached to the inner ring of the xianwei bearing, and the limit bearing 12 plays an axial and radial limiting role in the positioning part 2 at the moment.
In order to achieve the above effect, the positioning portion 2 includes a positioning sleeve 21 and a guide sleeve 22 provided on one side of the positioning sleeve 21. One side of the positioning sleeve 21 facing the stator housing 11 is provided with a notch suitable for installing the guide sleeve 22, and after the guide sleeve 22 is installed in the notch, a suitable bolt is selected for use, so that the positioning sleeve 21 and the guide sleeve 22 can be fixedly connected. In order to ensure the matching accuracy of the positioning sleeve 21 and the stator housing 11 and further ensure that the guide sleeve 22 can correctly guide the rotor assembly 4 to be installed at a correct position, the positioning sleeve 21 and the stator housing 11 are coaxially arranged, and when the positioning sleeve 21 moves to abut against the limit bearing 12, a proper bolt is selected, so that the positioning sleeve 21 and the stator housing 11 can be fixedly connected. Meanwhile, the positioning sleeve 21 and the guide sleeve 22 are coaxially arranged, and the diameter of the outer wall of the guide sleeve 22 is matched with the diameter of the inner wall of the rotor assembly 4. Through the arrangement, after the positioning sleeve 21 and the guide sleeve 22 are installed, the inner wall of the rotor assembly 4 is sleeved on the outer wall of the guide sleeve 22, so that the rotor assembly 4 can slide along the axial direction of the guide sleeve 22, and the coaxiality of the rotor assembly 4 and the stator shell 11 during installation is ensured.
In order to further ensure the radial limitation of the guide sleeve 22 by the positioning sleeve 21. A limiting ring 23 is arranged on one side of the positioning sleeve 21, the outer side wall of the limiting ring 23 is attached to the inner wall of the limiting bearing 12, and the inner wall of the limiting ring 23 is attached to the outer wall of the guide sleeve 22. Through the arrangement, the limiting ring 23 is inserted into the limiting bearing 12, so that after the limiting ring 23 radially limits the positioning sleeve 21, the limiting ring 23 can limit the guide sleeve 22.
The driving part 3 is detachably fixed on one side of the positioning sleeve 21 far away from the stator shell 11. The driving part 3 and the positioning sleeve 21 are coaxially arranged, and the rotor assembly 4 is detachably fixed on the driving part 3. With the above arrangement, after the positioning part 2 is installed, the driving part 3 passes through the stator assembly 1 and is fixed on the positioning sleeve 21. After the rotor assembly 4 is installed, the driving part 3 rotates circumferentially to drive the rotor assembly 4 to slide until the rotor assembly is inserted into the stator assembly 1. When the rotor assembly 4 is installed, the driving part 3 drives the rotor assembly 4 to slide along the outer wall of the positioning part 2 to the other side of the limit bearing 12 to be abutted.
The structure of the driving part 3 is specifically described below, and the driving part 3 includes a positioning assembly 31 and a screw assembly 32. The positioning component 31 is fixedly arranged below the positioning part 2, and the screw rod component 32 is detachably and rotatably connected with the rotor component 4. The screw rod assembly 32 is rotatably connected with the positioning assembly 31. Through the matching of the screw rod assembly 32 and the positioning assembly 31, when the screw rod assembly 32 rotates, the screw rod assembly 32 drives the rotor assembly 4 to slide along the positioning part 2, so that the rotor assembly 4 is inserted into the stator body until being abutted against the limit bearing 12.
In order to achieve the above effect, the screw rod assembly 32 includes a threaded rod 321, a threaded sleeve 322 sleeved on the outer wall of the screw rod, a linkage plate 323 sleeved on the outer wall of the threaded sleeve 322, and a plurality of connecting rods 324 arranged on the linkage plate 323. The threaded rod 321 is rotatably connected with the positioning component 31, and the guide sleeve 22 and the threaded rod 321 are coaxially arranged. The threaded sleeve 322 is threadedly connected to the threaded rod 321. The linkage plate 323 is fixedly connected with the threaded sleeve 322. One end of the connecting rod 324 is fixedly connected with the threaded rod 321, and the other end is detachably and fixedly connected with the rotor assembly 4. Through the above arrangement, when the threaded rod 321 rotates, the rotor assembly 4 is restricted from rotating due to the magnetic force between the rotor assembly 4 and the stator housing 11, and the rotor assembly 4 cannot rotate, so that the rotor assembly 4 does not rotate synchronously with the screw rod assembly 32, but slides up and down along the guide sleeve 22. It should be noted that the magnetic force does not make the rotor assembly 4 not rotate at all, but may exhibit a certain degree of swing, so that if the swing amplitude is too large to affect the lifting of the rotor assembly 4, the swing may be reduced by the way that an operator holds the rotor assembly 4.
In order to facilitate the operator to rotate the threaded rod 321, a hand wheel 33 is fixedly arranged at one end of the threaded rod 321 far away from the positioning assembly 31.
In order to limit the position of the threaded rod 321 and ensure the coaxiality of the threaded rod 321 for driving the rotor assembly 4 to ascend and descend, the positioning assembly 31 comprises a positioning plate 311 and a connecting piece 312 arranged at the center of the positioning plate 311. The positioning plate 311 is disposed below the positioning portion 2, and two ends of the positioning plate 311 are fixedly connected to the positioning sleeve 21. The connecting piece 312 penetrates through the positioning plate 311 along the thickness direction, a movable groove 313 is formed in one side, facing the threaded rod 321, of the connecting piece 312, and one end of the threaded rod 321 is rotatably arranged in the movable groove 313. The coaxiality of the threaded rod 321 and the stator housing 11 can be ensured by the cooperation of the movable groove 313 and the threaded rod 321 and the cooperation of the guide sleeve 22 and the rotor assembly 4.
When the stator is installed, the positioning sleeve 21 and the guide sleeve 22 are fixed, and then the stator is integrally installed on the stator housing 11, and the positioning plate 311 and the connecting member 312 are installed. The rotor assembly 4 is then mounted onto the connecting rod 324, and finally the threaded rod 321 is inserted into the connecting rod 324. Thereby avoiding the impact to the motor bearing in the assembling and disassembling process, resulting in the damage of the bearing and causing unnecessary waste.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
