Description

Technical Field

[0001] This utility model relates to the field of encoder technology, specifically to a high-bit magnetoelectric encoder. Background Technology

[0002] A high-bit magnetoelectric encoder is a device that achieves high-precision angle measurement based on the principle of magnetoelectric induction. Its core feature lies in its ability to output high-bit absolute angle encoded signals through a high-resolution magnetic grating structure combined with precision sensing elements. These encoders, with their advantages of strong anti-interference capability, fast response speed, and wide measurement range, are widely used in scenarios with stringent requirements for angle detection accuracy, such as joint control of industrial robots and spindle positioning of precision CNC machine tools.

[0003] In the existing technology, the connection between the encoder and the mounting base is mostly achieved by rigid bolt fastening or rigid bushing fit. Although this structure can meet the static installation requirements, when the equipment is running and vibrates, the rigid connection cannot absorb the vibration energy, which can easily cause relative displacement between the encoder and the measured shaft, causing the output signal to jitter periodically or lose the signal, ultimately leading to inaccurate equipment control or even shutdown failure. Utility Model Content

[0004] This invention proposes a high-bit magnetoelectric encoder, which solves the problem in related technologies where rigid connections cannot absorb vibration energy when equipment is running and vibration occurs, which easily causes relative displacement between the encoder and the measured shaft.

[0005] The technical solution of this utility model is as follows: A high-number magnetoelectric encoder includes a high-number magnetoelectric encoder body and a base. A support assembly is provided on the base. A buffer assembly is fixedly connected between the base and the support assembly. Several buffer assemblies are provided. The high-number magnetoelectric encoder body is fixedly connected to the support assembly. The buffer assembly includes a fixed rod. A threaded rod is fixedly connected to the top of the fixed rod. A knob is threadedly connected to the threaded rod. A buffer ball is fixedly connected to the top of the knob. The buffer ball is made of highly elastic rubber material. A sliding hole is provided inside the buffer ball. The diameter of the sliding hole is slightly larger than the diameter of the threaded rod.

[0006] Preferably, the buffer ball slides on the threaded rod, and a mounting plate is rotatably mounted on the top of the buffer ball, the mounting plate being provided with threaded holes.

[0007] Preferably, the base has a plurality of mounting holes, and the buffer assembly is mounted on each mounting hole.

[0008] Preferably, the bottom of the fixing rod is provided with a threaded hole, and a fastening bolt is threaded to the end of the fixing rod, so that the fixing rod is fixed to the mounting hole of the base by using the fastening bolt.

[0009] Preferably, the bracket assembly includes a fixed bracket, which has a plurality of mounting slots and a plurality of positioning holes, and is fixedly connected to the mounting plate.

[0010] Preferably, the top of the fixed bracket is fixedly connected to a connector, there are two connectors arranged in pairs, and one side of the connector is fixedly connected to the bracket of the rotating shaft being measured.

[0011] Preferably, the side of the bracket assembly is provided with a fixing groove, and a buffer pad is fixedly connected to the fixing groove.

[0012] The beneficial effects of this utility model are as follows:

[0013] This invention features excellent shock absorption and buffering capabilities. The buffer ball effectively absorbs the vibration energy of the working equipment, while the buffer pad further reduces the impact of bracket vibration, preventing angular deviation or radial offset between the high-digit magnetoelectric encoder body and the measured shaft caused by vibration. This ensures detection accuracy and overall working stability. Furthermore, it facilitates fine-tuning of the height. By rotating the knob, the buffer ball can be moved along the threaded rod, thereby adjusting the height of the high-digit magnetoelectric encoder body. This enables precise alignment between the high-digit magnetoelectric encoder body and the measured shaft, improving the convenience of installation and debugging. Attached Figure Description

[0020] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0021] Example

[0022] like Figures 1-4 As shown, this embodiment proposes a high-digit magnetoelectric encoder, including a high-digit magnetoelectric encoder body 1 and a base 2. A support assembly 4 is provided on the base 2, and a buffer assembly 3 is fixedly connected between the base 2 and the support assembly 4. Several buffer assemblies 3 are provided. The high-digit magnetoelectric encoder body 1 is fixedly connected to the support assembly 4. The high-digit magnetoelectric encoder body 1 is fixed by using the support assembly 4, and the support assembly 4 and the high-digit magnetoelectric encoder body 1 are buffered by several buffer assemblies 3. The buffer assembly 3 includes a fixing rod 301, a threaded rod 303 is fixedly connected to the top of the fixing rod 301, a knob 304 is threadedly connected to the threaded rod 303, and a buffer ball 305 is fixedly connected to the top of the knob 304. The buffer ball 305 is made of highly elastic rubber material, and a sliding hole is provided inside the buffer ball 305. The diameter of the sliding hole is slightly larger than the diameter of the threaded rod 303.

[0023] The buffer ball 305 slides on the threaded rod 303. The top of the buffer ball 305 is rotatably mounted with a mounting plate 306. The mounting plate 306 is provided with threaded holes. When the equipment vibrates, the buffer ball 305 can absorb radial and axial vibration energy through its own elastic deformation and slight sliding along the threaded rod 306 to achieve a shock absorption effect. This prevents the vibration of the working equipment from affecting the angular deviation or radial offset between the high-digit magnetoelectric encoder body 1 and the measured shaft, which would affect the detection of the high-digit magnetoelectric encoder body 1. By rotating the knob 304, the height of the buffer ball 305 can be adjusted, thereby adjusting the height of the bracket assembly 4, and thus the height of the high-digit magnetoelectric encoder body 1 can be slightly adjusted.

[0024] The base 2 has several mounting holes 5, and the buffer assembly 3 is installed in each mounting hole 5 respectively;

[0025] The bottom of the fixing rod 301 is provided with a threaded hole, and the fastening bolt 302 is threaded to the end of the fixing rod 301. By using the fastening bolt 302, the fixing rod 301 is fixed to the mounting hole 5 of the base 2, so as to achieve quick fixation.

[0026] like Figure 4As shown, the bracket assembly 4 includes a fixed bracket 401, which has several mounting slots 402 and several positioning holes 403 for fixing the high-digit magneto-electric encoder body 1. The fixed bracket 401 is fixedly connected to the mounting plate 306. The fixed bracket 401 is fixed to the mounting plate 306 by using bolts passing through the mounting slots 402.

[0027] The top of the fixed bracket 401 is fixedly connected to a connector 406. There are two connectors 406, which are set in pairs. One side of the connector 406 is fixedly connected to the bracket of the rotating shaft being measured.

[0028] The side of the bracket assembly 4 is provided with a fixing groove 404, and a buffer pad 405 is fixedly connected to the fixing groove 404. When the fixed bracket 401 is fixed to the bracket of the rotating shaft under test, the impact of the bracket vibration on the fixed bracket 401 is reduced by using the buffer pad 405.

[0029] Working principle: First, the base 2 is fixed to the designated position of the working equipment through several mounting holes 5. Then, the buffer assembly 3 is installed. Each buffer assembly 3 is fixed to the base 2 through the threaded hole at the bottom of the fixing rod 301 and the fastening bolt 302 passes through the mounting hole 5 of the base 2, so that the fixing rod 301 is firmly fixed to the base 2, realizing the quick connection between the buffer assembly 3 and the base 2. Next, the bracket assembly 4 is installed. The fixing bracket 401 is fixed to the mounting plate 306 through several mounting slots 402. Bolts pass through the mounting slots 402 and connect to the threaded holes on the mounting plate 306, so that the fixing bracket 401 is fixed to the mounting plate 306, so that the bracket assembly 4 and the buffer assembly 3 form a stable connection. After that, the high-digit magnetoelectric encoder body 1 is installed and fixedly connected to the positioning hole 403 on the fixing bracket 401, thus completing the installation and positioning of the high-digit magnetoelectric encoder body 1.

[0030] During use, the height can be adjusted by rotating the knob 304. Rotating the knob 304 can drive the buffer ball 305 to move up and down along the threaded rod 303, thereby adjusting the height of the bracket assembly 4 and the high-digit magnetoelectric encoder body 1 through the mounting plate 306, realizing a small adjustment of the height of the high-digit magnetoelectric encoder body 1, and ensuring that it is accurately aligned with the shaft being measured.

[0031] Meanwhile, the buffer ball 305 can absorb the vibration of the working equipment, avoid the vibration causing angular deviation or radial offset between the high-digit magneto-electric encoder body 1 and the measured shaft, and ensure detection accuracy. When the fixed bracket 401 is fixedly connected to the bracket of the measured shaft through the connector 406, the buffer pad 405 can further reduce the impact of bracket vibration on the fixed bracket 401 and the high-digit magneto-electric encoder body 1, and improve the overall working stability.

[0032] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
