Description

Technical Field

[0001] This utility model relates to the field of encoders, and more specifically, to a high-precision concentric rotary encoder device. Background Technology

[0002] In existing encoder assembly, the encoder is typically fixed to a circuit board, which is then securely installed inside the device to secure the encoder. However, the encoder knob is directly fitted onto the half-shaft handle. Because the knob is not restrained, rotation is prone to wobbling and lacks flexibility. Summary of the Invention

[0003] This invention addresses the aforementioned deficiencies in the prior art by providing a high-precision concentric rotary encoder device.

[0004] The technical solution adopted by this utility model to solve its technical problem is: to construct a high-precision concentric rotary encoder device, the encoder device including a circuit board, an encoder fixedly mounted on the circuit board, a knob sleeved on the half shaft of the encoder, a bearing sleeved on the knob, and a fixing frame fixedly connected to the encoder and sleeved outside the bearing. The mounting bracket includes a sleeve and a fixing plate fixed to the side wall of the sleeve. The sleeve has a mounting hole for accommodating the bearing, knob, and half-shaft. The inner ring of the bearing abuts against the knob, and the outer ring of the bearing abuts against the inner side wall of the mounting hole. The first end of the sleeve has a first opening for inserting the bearing and knob. The second end of the sleeve has an end cap fixed. The encoder also has a threaded section. The encoder device also includes a locking nut that can be screwed into the threaded section. The end cap has a second opening for inserting the half-shaft and threaded section of the encoder. When the half-shaft and threaded section are inserted into the mounting hole, the locking nut screws into the threaded section and locks the encoder.

[0005] In the high-precision concentric rotary encoder device of this utility model, the fixing plate is provided with multiple fixing holes for fixing the fixing frame.

[0006] In the high-precision concentric rotary encoder device of this utility model, the knob includes a handle and a connecting sleeve fixedly connected to the handle. The connecting sleeve is provided with a half-shaft hole for the half-shaft handle to be inserted and connected, and the bearing is sleeved on the connecting sleeve.

[0007] In the high-precision concentric rotary encoder device of this utility model, the connecting sleeve is provided with a threaded hole extending to the half shaft hole, and a locking screw is provided in the threaded hole that can be screwed into the threaded hole and pass through the threaded hole to abut against the half shaft handle.

[0008] In the high-precision concentric rotary encoder device described in this utility model, the locking screw is a headless screw.

[0009] In the high-precision concentric rotary encoder device described in this utility model, the side wall of the sleeve is provided with a through hole through which the locking screw can pass.

[0010] In the high-precision concentric rotary encoder device of this utility model, a washer is also fitted on the threaded section, and the washer is sandwiched between the encoder and the locking nut.

[0011] In the high-precision concentric rotary encoder device described in this utility model, a cover plate covering the bearing is attached to the first end of the sleeve.

[0012] The high-precision concentric rotary encoder device of this utility model has the following beneficial effects: When using the high-precision concentric rotary encoder device of this utility model, the encoder's half-shaft and threaded section are inserted into the mounting hole through the second opening. Then, a cylindrical wrench is used to tighten the lock nut onto the threaded section from the inside of the mounting hole, thus achieving a fixed connection between the mounting bracket and the encoder. The mounting bracket is then fixed inside the electronic device using a fixing plate. Next, the bearing is fitted onto the knob, and the knob is inserted into the mounting hole, so that the knob is fitted onto the half-shaft until the inner ring of the bearing abuts against the knob, and the outer ring of the bearing abuts against the inner wall of the mounting hole. When rotating the knob, because the knob is fitted with a bearing, both the flexibility of the knob's rotation and the stability of the knob are improved, preventing it from shaking.

Detailed Implementation

[0014] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0015] like Figure 1-4As shown, in the first embodiment of the high-precision concentric rotary encoder device of this utility model, the encoder device 10 includes a circuit board 11, an encoder 12 fixedly mounted on the circuit board 11, a knob 13 sleeved on the half shaft 23 of the encoder 12, a bearing 14 sleeved on the knob 13, and a fixing frame 15 fixedly connected to the encoder 12 and sleeved outside the bearing 14.

[0016] The mounting bracket 15 includes a sleeve 16 and a fixing plate 17 fixed to the side wall of the sleeve 16. The sleeve 16 has a mounting hole 18 for accommodating the bearing 14, the knob 13 and the half-shaft shank 23. The inner ring of the bearing 14 abuts against the knob 13 and the outer ring of the bearing 14 abuts against the inner side wall of the mounting hole 18. The first end of the sleeve 16 has a first opening 19 for inserting the bearing 14 and the knob 13. The second end of the sleeve 16 is fixed with an end cap 20. The encoder 12 also has a threaded section 22. The encoder device 10 also includes a locking nut 21 that can be screwed into the threaded section 22. The end cap 20 has a second opening 24 for inserting the half-shaft shank 23 and the threaded section 22 of the encoder 12. When the half-shaft shank 23 and the threaded section 22 are inserted into the mounting hole 18, the locking nut 21 screws into the threaded section 22 and locks the encoder 12.

[0017] When using the high-precision concentric rotary encoder device of this utility model, the half-shaft shank 23 and threaded section 22 of the encoder 12 are inserted into the mounting hole 18 through the second opening 24. Then, a cylindrical wrench is used to tighten the locking nut 21 from the inside of the mounting hole 18 onto the threaded section 22, thus achieving a fixed connection between the fixing frame 15 and the encoder 12. After that, the fixing frame 15 is fixed inside the electronic device by the fixing plate 17. Next, the bearing 14 is sleeved on the knob 13, and the knob 13 is inserted into the mounting hole 18, so that the knob 13 is sleeved on the outside of the half-shaft shank 23 until the inner ring of the bearing 14 abuts against the knob 13, and the outer ring of the bearing 14 abuts against the inner sidewall of the mounting hole 18. When rotating the knob 13, since the knob 13 is sleeved with the bearing 14, it can improve the flexibility of the knob 13 rotation and increase the stability of the knob 13, preventing it from shaking.

[0018] To facilitate the fixing of the fixing plate 17 and the fixing bracket 15, the fixing plate 17 is provided with a plurality of fixing holes 25 for fixing the fixing bracket 15. Preferably, the plurality of fixing holes 25 are respectively provided at the corner positions of the fixing plate 17.

[0020] Furthermore, the connecting sleeve 27 is provided with a threaded hole 29 extending to the half shaft hole 28, and a locking screw 30 is provided in the threaded hole 29, which can be screwed into the threaded hole 29 and pass through the threaded hole 29 to abut against the half shaft handle 23.

[0021] When connecting the half-shaft handle 23 and the knob 13, first insert the half-shaft handle 23 into the half-shaft hole 28 of the connecting sleeve 27, and then use the locking screw 30 to tighten the screw connection with the threaded hole 29 until the locking screw 30 and the half-shaft handle 23 are pressed together to prevent the half-shaft handle 23 from coming out of the half-shaft hole 28.

[0022] Preferably, the locking screw 30 is a headless screw.

[0023] To facilitate the insertion and connection of the locking screw 30, the side wall of the sleeve 16 is provided with a through hole 31 through which the locking screw 30 can pass.

[0024] Furthermore, a washer 32 is fitted onto the threaded section 22, which is sandwiched between the encoder 12 and the locking nut 21.

[0025] To provide shielding and dust protection, a cover plate 33 is attached to the first end of the sleeve 16 to cover the bearing 14.

[0026] Furthermore, in this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," "stacked," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
