Description

Technical Field

[0001] This utility model belongs to the field of motor shaft technology, specifically relating to a shaft for a positioning motor. Background Technology

[0002] A positioning motor, also known as a position control motor or servo motor, is a type of motor that can precisely control rotation angle, position, speed, and acceleration. It is an auxiliary motor with indirect speed change, capable of controlling speed and achieving very accurate position. It can convert voltage signals into torque and speed to drive the controlled object. The motor shaft speed is controlled by the input signal and can respond quickly.

[0003] The existing technology, patent publication number CN222638298U, describes a motor shaft that can be quickly installed. This patent involves pressing a fixing rod, inserting it into a fixing hole, rotating the fixing rod, and twisting a spring to align a fixing block on the fixing rod and pass it through a limiting hole on a fixing plate. The lower end of the fixing rod secures the side shaft. Releasing the fixing rod causes the spring torque to displace the fixing block from the limiting hole, thus fixing the fixing rod in place. This achieves the purpose of quickly installing the motor shaft. However, in actual use, there are still the following shortcomings: In practice, the motor shaft is subjected to various mechanical forces and torques during operation. These external forces may be transmitted to the spring through the fixing rod, causing changes in the spring's stress state and thus altering its compression degree. This affects the clamping and fixing effect on the side shaft, thereby reducing the stability of the side shaft installation.

[0004] Therefore, a positioning motor shaft is needed to solve the problem in the existing technology where the motor shaft easily causes changes in the spring force state during operation, affecting the clamping and fixing effect of the opposite shaft. Utility Model Content

[0005] The purpose of this invention is to provide a rotating shaft for a positioning motor to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a rotating shaft for a positioning motor, comprising a connecting sleeve, a mounting mechanism, a fixing mechanism, a limiting mechanism, and a mounting shaft. The mounting mechanism is located on the right side of the connecting sleeve, the fixing mechanism is located outside the mounting mechanism, the limiting mechanism is located inside and above the mounting mechanism, and the mounting shaft is mounted on the right end of the connecting sleeve via the mounting mechanism and the fixing mechanism.

[0007] It should be noted in the solution that the installation mechanism consists of a fixed cylinder, a connecting block, and a fixing ring. The fixed cylinder is fixedly connected to the right side of the connecting sleeve. An annular cavity is opened inside the fixed cylinder. An installation groove is opened at the right end of the fixed cylinder. A slot is symmetrically opened on the left side of the installation groove. The connecting block is symmetrically fixedly connected to the right side of the fixed cylinder, and the fixing ring is fixedly connected to the right side of the connecting block.

[0008] It is worth noting that the fixing mechanism consists of a rotating ring, a ratchet, a limiting plate, a connecting column, a mounting block, a limiting block, and a clamping plate. The rotating ring is rotatably connected to the outside of the right side of the fixing cylinder. The ratchet is fixedly connected to the outside of the left end of the rotating ring and is located inside the annular cavity. The limiting plate is fixedly connected to the inside of the rotating ring. The limiting plate has three symmetrically arranged arc-shaped grooves inside, which are symmetrically arranged along the center of the limiting plate.

[0009] Furthermore, it should be noted that the connecting column is slidably connected to the inside of the arc-shaped groove, the mounting block is fixedly connected to the right side of the connecting column, the limiting block is fixedly connected to the right side of the mounting block, and the left side of the fixing ring is symmetrically provided with a rectangular groove that matches the limiting block, and the limiting block is slidably connected to the inside of the rectangular groove.

[0010] In a preferred embodiment, the clamping plate is fixedly connected to the side of the mounting block near the center of the limiting plate. There are three connecting blocks, which are symmetrically arranged along the center of the limiting plate, and the clamping plates are staggered between the connecting blocks.

[0011] In a preferred embodiment, the limiting mechanism consists of a fixed post, a ratchet, a handle, and a torsion spring. The fixed post is fixedly connected to the upper part of the inside of the fixed cylinder, the ratchet is rotatably connected to the outside of the fixed post, the handle is fixedly connected above the ratchet, the torsion spring is symmetrically fixedly connected between the ratchet and the fixed cylinder, and the torsion spring is sleeved on the outside of the fixed post. The limiting mechanism is located above the rotating ring.

[0012] In a preferred embodiment, the mounting shaft consists of a rotating shaft body, inserts, and a limiting ring. The inserts are symmetrically and fixedly connected to the left end of the rotating shaft body, and the inserts are adapted to the slots. The limiting ring is fixedly connected to the outside of the rotating shaft body.

[0013] In a preferred embodiment, limiting grooves are uniformly formed on the outer side of the limiting ring and the inner side of the clamping plate.

[0014] Compared with the prior art, the positioning motor shaft provided by this utility model has at least the following beneficial effects:

[0015] (1) By using the installation mechanism, fixing mechanism and limiting mechanism, the installation shaft can be quickly installed on the right side of the connecting sleeve by rotating the rotating ring. No complicated operation steps and tools are required, which improves installation efficiency and saves installation time. The limiting mechanism can accurately limit the rotation direction of the rotating ring during the installation process, ensuring that the installation shaft is installed in place and avoiding problems such as abnormal operation or damage of the rotating shaft caused by installation position deviation or reverse rotation.

[0023] The present invention will be further described below with reference to the embodiments.

[0024] Please see Figure 1-4This utility model provides a rotating shaft for a positioning motor, including a connecting sleeve 1, a mounting mechanism 2, a fixing mechanism 3, a limiting mechanism 4, and a mounting shaft 5.

[0025] Further as Figure 2 , Figure 3 and Figure 4 As shown, it is worth noting that the installation mechanism 2 consists of a fixed cylinder 201, a connecting block 205, and a fixing ring 206. The fixed cylinder 201 is fixedly connected to the right side of the connecting sleeve 1. An annular cavity 202 is provided inside the fixed cylinder 201. An installation groove 203 is provided at the right end of the fixed cylinder 201. A slot 204 is symmetrically provided on the left side of the installation groove 203. The connecting block 205 is symmetrically fixedly connected to the right side of the fixed cylinder 201, and the fixing ring 206 is fixedly connected to the right side of the connecting block 205.

[0026] Further as Figure 2 , Figure 3 and Figure 4 As shown, it is worth noting that the fixing mechanism 3 consists of a rotating ring 301, a ratchet 302, a limiting plate 303, a connecting column 305, a mounting block 306, a limiting block 307, and a clamping plate 308. The rotating ring 301 is rotatably connected to the outside of the right side of the fixing cylinder 201. The ratchet 302 is fixedly connected to the outside of the left end of the rotating ring 301 and is located inside the annular cavity 202. The limiting plate 303 is fixedly connected to the inside of the rotating ring 301. The limiting plate 303 has three symmetrically arranged arc-shaped grooves 304 inside, which are symmetrically arranged along the center of the limiting plate 303.

[0027] Further as Figure 2 , Figure 3 and Figure 4 As shown, it is worth noting that the connecting post 305 is slidably connected to the inside of the arc-shaped groove 304, the mounting block 306 is fixedly connected to the right side of the connecting post 305, the limiting block 307 is fixedly connected to the right side of the mounting block 306, and the left side of the fixing ring 206 is symmetrically provided with a rectangular groove 207 that matches the limiting block 307, and the limiting block 307 is slidably connected to the inside of the rectangular groove 207.

[0028] Further as Figure 2 , Figure 3 and Figure 4As shown, it is worth noting that the clamping plate 308 is fixedly connected to the side of the mounting block 306 near the center of the limiting plate 303. There are three connecting blocks 205, which are symmetrically arranged along the center of the limiting plate 303. The clamping plates 308 are staggered between the connecting blocks 205.

[0029] Further as Figure 2 , Figure 3 and Figure 4 As shown, it is worth noting that the limiting mechanism 4 consists of a fixed post 401, a ratchet 402, a handle 403, and a torsion spring 404. The fixed post 401 is fixedly connected to the upper part of the fixed cylinder 201. The ratchet 402 is rotatably connected to the outside of the fixed post 401. The handle 403 is fixedly connected above the ratchet 402. The torsion spring 404 is symmetrically fixedly connected between the ratchet 402 and the fixed cylinder 201, and the torsion spring 404 is sleeved on the outside of the fixed post 401. The limiting mechanism 4 is located above the rotating ring 301.

[0030] Further as Figure 2 , Figure 3 and Figure 4 As shown, it is worth noting that the mounting shaft 5 is composed of a rotating shaft body 501, a plug 502 and a limiting ring 503. The plug 502 is symmetrically fixedly connected to the left end of the rotating shaft body 501, and the plug 502 is adapted to the slot 204. The limiting ring 503 is fixedly connected to the outside of the rotating shaft body 501. Limiting grooves 504 are evenly provided on the outside of the limiting ring 503 and the inside of the clamping plate 308.

[0031] The clamping plate 308 and the limiting groove 504 on the limiting ring 503 are interlocked to form a tight fixed structure that can withstand large torque and vibration, ensuring that the mounting shaft 5 will not loosen or fall off during operation.

[0032] The solution has the following working process: In use, the middle of the connecting sleeve 1 is provided with a connecting slot for connecting with an external servo motor. The connecting sleeve 1 is connected to the external servo motor through the connecting slot. The insert 502 is aligned with the slot 204 on the right end of the fixed cylinder 201 and inserted to ensure the initial installation of the rotating shaft body 501 and the fixed cylinder 201. Then, the rotating ring 301 is rotated. Since the rotating ring 301 is rotatably connected to the right side of the fixed cylinder 201, the ratchet 302 rotates accordingly in the annular cavity 202. The limiting plate 303 fixed inside the rotating ring 301 also rotates. The three arc-shaped grooves 304 symmetrically opened inside the limiting plate 303 will drive the connecting post 305 slidably connected inside to move. The connecting post 305 drives the mounting block 306 to move. The mounting block 306 then drives the limiting block 307 and the clamping plate 308 to move. The limiting block 307 slides along the rectangular groove 207 symmetrically opened on the left side of the fixing ring 206, causing the clamping plate 308 to gradually approach the limiting ring 503. The limiting groove 504 on the inner wall of the clamping plate 308 and the limiting groove 504 on the outer side of the limiting ring 503 engage with each other, firmly fixing the mounting shaft 5 to the right end of the connecting sleeve 1. At this point, the installation is complete. Simultaneously, the ratchet 402 in the limiting mechanism 4, under the action of the torsion spring 404, engages with the ratchet 302, restricting the rotating ring 301 to rotate only in one direction, preventing it from reversing and causing the mounting shaft 5 to loosen. When reverse operation is required, the ratchet 402 can be disengaged from the ratchet 302 by operating the handle 403.

[0033] In summary: The installation mechanism 2, fixing mechanism 3, and limiting mechanism 4 allow for quick installation of the mounting shaft 5 onto the right side of the connecting sleeve 1 by rotating the rotating ring 301, eliminating the need for complex operating procedures and tools, thus improving installation efficiency and saving time. The limiting mechanism 4 accurately restricts the rotation direction of the rotating ring 301 during installation, ensuring the mounting shaft 5 is properly installed and preventing abnormal operation or damage to the shaft due to installation position deviation or reverse rotation. The clamping plate 308 and the limiting groove 504 on the limiting ring 503 interlock to form a tight fixing structure capable of withstanding significant torque and vibration, ensuring the mounting shaft 5 will not loosen or fall off during operation, thus improving the stability and reliability of the shaft. The reasonable design and tight cooperation between the components of the installation mechanism 2, fixing mechanism 3, limiting mechanism 4, and mounting shaft 5 result in a compact overall structure that occupies little space, facilitating installation and use in various equipment while also reducing the overall weight and cost of the equipment.
