Description

Technical Field

[0001] This utility model belongs to the field of servo motor technology, specifically relating to a servo motor that prevents deviation. Background Technology

[0002] Servo motors can control speed and position with extremely high accuracy. They can convert voltage signals into torque and speed to drive the controlled object. The rotor speed of a servo motor is controlled by the input signal and can respond quickly. In automatic control systems, they are used as actuators. Modern servo motors, through their own operation, drive the output terminal to rotate, providing power for the operation of connected components.

[0003] Current servo motors are used by connecting their output to external components, which is a common practice. However, there are some problems in actual use. Specifically, existing servo motors cannot accurately detect the angle and position of the output, which makes it difficult for operators to repair and adjust them in time when the servo motor deviates.

Detailed Implementation

[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0024] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. The present invention provides the following embodiments.

[0025] like Figure 1 and Figure 2 As shown, it is a structural schematic diagram of the anti-deviation servo motor in this embodiment. The servo motor includes a motor body 1, an output shaft 2 and a mounting block 3. The output shaft 2 is installed at the end of the motor body 1, and the mounting block 3 is installed on the surface of the motor body 1.

[0026] The servo motor is installed at the target position, and then the output shaft 2 is connected to the component to be driven. When the motor body 1 is running, the output shaft 2 provides power for the operation of the component. The installation block 3 facilitates the installation and fixation of the motor body 1.

[0027] In this embodiment, a protective mechanism 4 is provided outside the output shaft 2. The protective mechanism 4 surrounds the output shaft 2, and a fixing mechanism 5 is provided at the end of the protective mechanism 4.

[0028] As attached Figure 3 and Figure 4As shown, the protective mechanism 4 includes a fixed bracket 41, an inclined rod 42, and a protective plate 43. The fixed bracket 41 is equidistantly installed on the outside of the output shaft 2. An inclined rod 42 is installed at the end of the fixed bracket 41, and a protective plate 43 is installed at the end of the inclined rod 42. There are four sets of protective plates 43, which surround the outside of the output shaft 2. An actuating component 44 is installed inside the protective plate 43. An alarm 45 is installed on the side of the fixed bracket 41. The actuating component 44 is electrically connected to the alarm 45. A protective ring 46 is installed on the outside of the fixed bracket 41. The protective ring 46 is circular.

[0029] In use, supported by the fixed bracket 41 and the tilting rod 42, multiple sets of protective plates 43 surround the output shaft 2. The protective plates 43 do not directly contact the output shaft 2. When the output shaft 2 is running in a normal state, the protective plates 43 will not affect the operation of the output shaft 2. The protective ring 46 installed outside the fixed bracket 41 provides protection and support for the output shaft 2, preventing external impurities from falling and colliding with the output shaft 2, which could cause the output shaft 2 to tilt or deviate. Subsequently, under the action of the trigger component 44 and the alarm 45, when the output shaft 2 deviates, it will quickly respond and alert the operator that the output shaft 2 has deflected.

[0030] As attached Figure 5 As shown, this is a schematic diagram of the structure of the trigger component 44 in this embodiment. The trigger component 44 includes a pressing block 441, a contact piece 442, and an electrode piece 443. A sliding groove is provided in the protective plate 43. The pressing block 441 is slidably installed in the sliding groove. The contact piece 442 is installed at the end of the pressing block 441. The electrode pieces 443 are symmetrically installed on the inner wall of the sliding groove. The electrode pieces 443 and the contact piece 442 are in pressing contact. A spring assembly 444 is installed on the contact piece 442. The other end of the spring assembly 444 is connected to the inner wall of the sliding groove. A wire is installed at the end of the electrode piece 443. The wire is electrically connected to the alarm 45.

[0031] When the output shaft 2 deflects, the outside of the output shaft 2 collides with the pressing block 441. At this time, the pressing block 441 moves into the sliding groove due to the pressure of the output shaft 2. The pressing block 441 pushes the contact piece 442 to slide inside the sliding groove. The end of the contact piece 442 contacts the electrode piece 443. At this time, the circuit of the electrode piece 443 and the wire connected to the end of the electrode piece 443 is closed. At this time, the alarm 45 sounds an alarm to remind the operator that the output shaft 2 has deflected.

[0032] As attached Figure 3As shown, the fixing mechanism 5 includes an outer frame 51, a fixing seat 52, and a connecting rod 53. There are four sets of fixing brackets 41, of which three sets of fixing brackets 41 are externally mounted with connecting rods 53. The ends of the connecting rods 53 are connected to the outer frame 51. The outer frame 51 is composed of horizontal bars and vertical bars. The horizontal bars are set on the upper surface of the motor body 1, and the vertical bars are symmetrically arranged on the side of the motor body 1. The horizontal bars are connected to the vertical bars, and the fixing seat 52 is installed at the end of the vertical bars.

[0033] In use, the outer frame 51 is fitted to the outside of the motor body 1 by using the horizontal and vertical bars. Then, under the action of the fixing seat 52, the position of the motor body 1 is further locked to prevent the motor body 1 from being misaligned or shifted during use. Then, the fixing bracket 41 is connected to the outer frame 51 by the connecting rod 53 to enhance the stability of the connection between the components.

[0034] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present utility model. It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
