Technical Field

[0001] This utility model belongs to the field of motor concentricity detection technology, and in particular relates to a high-precision permanent magnet synchronous motor encoder mounting base. Background Technology

[0002] The encoder mounting bracket for a high-precision permanent magnet synchronous motor is a key component for ensuring the control accuracy of the motor. Its design and installation directly affect the feedback accuracy of the encoder and the stability of the system.

[0003] Traditional encoders require a mounting bracket to be installed on the motor first, followed by the encoder itself. However, when connecting the encoder to the mounting bracket, the operator usually needs to align the mounting plate on the encoder with the threaded holes on the mounting bracket and then secure it with screws. This installation method can lead to misalignment of the encoder's installation position, and the position needs to be frequently adjusted to align the mounting holes, making the installation process inconvenient and inefficient. Utility Model Content

[0004] The purpose of this utility model is to provide a high-precision permanent magnet synchronous motor encoder mounting base. By setting up an installation mechanism, the encoder can be quickly positioned and installed without the need for encoder support, making subsequent operations more convenient for staff. Finally, the positioning plate is fixed to the mounting base with bolts. This method does not require frequent alignment of holes during installation, making the operation simple and convenient. It solves the problem that when connecting the encoder to the mounting base, staff usually need to align the mounting plate on the encoder with the threaded holes on the mounting base, which is inconvenient and inefficient.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a high-precision permanent magnet synchronous motor encoder mounting base, including a motor, wherein the right side of the motor has several positioning slots and a threaded hole, and further includes:

[0007] The mounting mechanism is located at the output end of the motor and includes a mounting base and an encoder.

[0008] The mounting base is mounted on the motor, and the encoder is mounted on the mounting base.

[0009] Furthermore, a convex ring is fixedly connected to the side of the mounting base facing the encoder, and several positioning blocks are fixedly connected to the side of the mounting base facing the motor. A docking frame is provided in front of and behind the convex ring, and the docking frame is fixedly connected to the mounting base. Mounting plates are fixedly connected to the top and bottom of the encoder, and positioning plates are fixedly connected to the front and back of the encoder. U-shaped clips are installed on both positioning plates, and several positioning rods are fixedly connected to the side of the encoder facing the mounting base.

[0010] The docking frame is U-shaped and has a slot that matches the U-shaped locking block. The convex ring has several positioning holes, and the positioning rod is inserted into the positioning holes on the convex ring.

[0011] Furthermore, the mounting base has two insertion holes inside, and two threaded holes on the side of the mounting base facing the encoder;

[0012] The insertion hole corresponds to the threaded hole, and the insertion hole is used to insert a bolt.

[0013] Furthermore, the positioning block on the left side of the mounting base is adapted to the shape of the positioning groove, the positioning block and the positioning groove are positioned and inserted, the end of the mounting plate is provided with a slot, the slot corresponds to the threaded hole, and the U-shaped card block is inserted into the slot on the docking frame.

[0014] Furthermore, the top and bottom of the U-shaped card block are fixedly connected with protrusions, the outer arc surface of the protrusions is the snap-fit ​​surface, and the inner side of the U-shaped card block is fixedly connected with a spring piece, which is used to assist the U-shaped card block in rebounding and resetting.

[0015] Furthermore, a square insert is fixedly connected to the side of the U-shaped card block facing the positioning plate, and a threaded shaft is fixedly connected to the side of the square insert block away from the U-shaped card block, with a locking nut threadedly connected to the outer side of the threaded shaft.

[0016] Furthermore, the end of the positioning plate is provided with a square groove that matches the shape of the square insert, and the U-shaped card block is positioned and inserted into the square groove on the positioning plate through the square insert.

[0017] This utility model has the following beneficial effects:

[0018] 1. This utility model, through the setting of an installation mechanism, specifically, connects the mounting base to the positioning groove on the motor via the positioning block on the left side, and then fixes it with bolts. Next, the encoder is inserted into the convex ring via the positioning rod on the left side, thereby positioning the encoder during installation. The U-shaped clip is inserted into the docking frame to easily fix the encoder. At this time, there is no need to support the encoder, which makes it more convenient for the staff to operate later. Finally, the positioning plate is fixed to the mounting base with bolts. This method does not require frequent alignment of the holes during installation, and the operation is simple and convenient.

[0019] 2. This utility model uses a square insert block. Specifically, when the U-shaped clip is fatigued, the locking nut can be turned counterclockwise to disassemble it, which allows the U-shaped clip block to be pulled off. This separates the square insert block and the threaded shaft from the positioning plate, allowing a new U-shaped clip block to be installed. This method enables quick replacement of the U-shaped clip block, and timely replacement of the U-shaped clip block can better assist in encoder installation.

[0030] Please see Figures 1-5 As shown, this utility model is a high-precision permanent magnet synchronous motor encoder mounting base, including a motor 1. The right side of the motor 1 has several positioning slots 11 and threaded holes 12. It also includes:

[0031] Mounting mechanism 2 is located at the output end of motor 1. Mounting mechanism 2 includes mounting base 21 and encoder 22.

[0032] The mounting base 21 is mounted on the motor 1, and the encoder 22 is mounted on the mounting base 21.

[0033] A protruding ring 211 is fixedly connected to the side of the mounting base 21 facing the encoder 22. Several positioning blocks 215 are fixedly connected to the side of the mounting base 21 facing the motor 1. A docking frame 212 is provided in front of and behind the protruding ring 211. The docking frame 212 is fixedly connected to the mounting base 21. Mounting plates 221 are fixedly connected to the top and bottom of the encoder 22. Positioning plates 222 are fixedly connected to the front and back of the encoder 22. U-shaped clips 23 are installed on both positioning plates 222. Several positioning rods 223 are fixedly connected to the side of the encoder 22 facing the mounting base 21. The mounting base 21 is aligned with the positioning slot 11 on the motor 1 via the positioning block 215 on the left side, and then fixed with bolts. The encoder 22 is then inserted into the convex ring 211 via the positioning rod 223 on the left side, thereby positioning the encoder 22 during installation. The U-shaped clip 23 is then inserted into the docking bracket 212 to easily fix the encoder 22. At this time, it is not necessary to support the encoder 22, which makes it more convenient for the staff to operate later. Finally, the positioning plate 222 is fixed to the mounting base 21 with bolts. This method does not require frequent alignment of the holes during installation, and the operation is simple and convenient.

[0034] The docking frame 212 is U-shaped and has a slot 213 that matches the U-shaped locking block 23. The convex ring 211 has several positioning holes, and the positioning rod 223 is inserted into the positioning holes on the convex ring 211.

[0035] The mounting base 21 has two insertion holes 216 inside, and two threaded holes 214 on the side of the mounting base 21 facing the encoder 22.

[0036] The insertion hole 216 corresponds to the threaded hole 12, and the insertion hole 216 is used to insert a bolt.

[0037] The positioning block 215 on the left side of the mounting base 21 is adapted to the shape of the positioning groove 11. The positioning block 215 is positioned and inserted into the positioning groove 11. The end of the mounting plate 221 has a slot, which corresponds to the threaded hole 214. The U-shaped card block 23 is inserted into the slot 213 on the docking frame 212.

[0038] Both the top and bottom of the U-shaped locking block 23 are fixedly connected to protrusions 231. The outer arc surface of the protrusions 231 is the locking surface. The inner side of the U-shaped locking block 23 is fixedly connected to a spring piece 232, which is used to assist the U-shaped locking block 23 in rebounding and resetting.

[0039] A square insert 233 is fixedly connected to the side of the U-shaped locking block 23 facing the positioning plate 222. A threaded shaft 234 is fixedly connected to the side of the square insert 233 away from the U-shaped locking block 23. A locking nut 235 is threadedly connected to the outer side of the threaded shaft 234. A square groove matching the shape of the square insert 233 is opened at the end of the positioning plate 222. The U-shaped locking block 23 is positioned and inserted into the square groove on the positioning plate 222 through the square insert 233. When the U-shaped locking block 23 becomes fatigued, the locking nut 235 can be rotated counterclockwise to remove it, and the U-shaped locking block 23 can be pulled off. Then the square insert 233 and the threaded shaft 234 are separated from the positioning plate 222, and a new U-shaped locking block 23 can be installed. This method can quickly replace the U-shaped locking block 23. By replacing the U-shaped locking block 23 in a timely manner, the installation of the encoder 22 can be better assisted.

[0040] One specific application of this embodiment is:

[0041] In use, the mounting base 21 is aligned with the positioning slot 11 on the motor 1 via the positioning block 215 on the left side, positioning the mounting base 21 on the motor 1. The insertion hole 216 will align with the threaded hole 12. At this time, a bolt is inserted into the insertion hole 216 and threaded into the threaded hole 12 to fix the mounting base 21 on the motor 1. Then, the encoder 22 is inserted into the convex ring 211 via the positioning rod 223 on the left side, thus positioning the encoder 22 during installation. At this time, the mounting plate 221 will align with the threaded hole 214, and the U-shaped locking block 23 on the positioning plate 222 will align with the slot 213 on the docking bracket 212. The encoder 22 is then pushed and pressed. The U-shaped locking block 23 is inserted into the docking frame 212. During docking, the protrusion 231 is pushed, thereby squeezing both ends of the U-shaped locking block 23 and the spring piece 232 is squeezed. When the protrusion 231 passes through the slot 213, it will be reset by the elastic force of the spring piece 232. Then the locking surface on the outside of the protrusion 231 will cooperate with the docking frame 212 to position and fix the encoder 22. The encoder 22 does not need to be supported by the staff, which facilitates the subsequent installation of bolts. Finally, the bolts are inserted into the mounting plate 221 and threaded into the threaded hole 214 to fix the encoder 22 on the mounting base 21, thus completing the installation. The model of the encoder 22 is (OMRON E6B2-CWZ6C).

[0042] After use, remove the bolts on the mounting plate 221 and pull the encoder 22 to remove it. Then remove the bolts on the mounting base 21 and pull the mounting base 21 to remove it. When the U-shaped locking block 23 becomes fatigued, turn the locking nut 235 counterclockwise to remove it. Then the U-shaped locking block 23 can be pulled to remove it. The square insert 233 and the threaded shaft 234 will then be separated from the positioning plate 222. Then insert the new U-shaped locking block 23 into the positioning plate 222 through the square insert 233 and thread the locking nut 235 onto the threaded shaft 234 to fix the U-shaped locking block 23.
