Description

Technical Field

[0001] This invention relates to the field of servo motor protection technology, specifically to an active protection servo motor and its usage method. Background Technology

[0002] Servo motors can control speed and position with extremely high accuracy. They 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 and have characteristics such as a small electromechanical time constant and high linearity. They can convert received electrical signals into angular displacement or angular velocity output on the motor shaft. Servo motors are divided into two main categories: DC and AC servo motors. Their main characteristic is that they do not rotate when the signal voltage is zero, and their speed decreases uniformly as the torque increases.

[0003] The protective structure of a servo motor is mainly used to protect the internal components of the motor from external environmental factors such as dust, moisture and mechanical impact. These structures typically include a corrosion-resistant housing, a sealing design and a heat dissipation system. By effectively preventing contaminants from entering the motor, the motor is ensured to operate normally under high loads and extreme temperatures, thereby improving the reliability and service life of the motor.

[0004] The existing protection structure for servo motors is relatively simple, and can only passively protect the servo motor. It cannot actively replace the protection, thus reducing the protection performance. Summary of the Invention

[0005] The purpose of this invention is to provide an active protection servo motor and its usage method, which has the advantages of active protection for servo motors. It adopts the method of actively changing the protection state to meet the protection needs of different protection operations, thereby improving the protection performance and solving the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an active protection servo motor and its usage method, comprising a servo motor body;

[0007] The top of the servo motor body is provided with a first protective mechanism for external protection, and the bottom of the servo motor body is provided with a second protective mechanism for external protection. The top of the first protective mechanism is provided with a shielding component for protection, and the bottom of the servo motor body is provided with a drive component for switching active protection mode. One end of the servo motor body is provided with a first heat dissipation mechanism for external heat dissipation, one end of the first heat dissipation mechanism is provided with a cleaning mechanism for end treatment, and one end of the cleaning mechanism is provided with a blower mechanism for external heat dissipation.

[0008] The first protective mechanism includes a support component and an elastic component. The support component is disposed on the outside of the servo motor body, and the elastic component is disposed on the top of the support component.

[0009] The second protective mechanism includes a connecting component and a protective component, wherein the connecting component is disposed inside the supporting component and the protective component is disposed outside the connecting component;

[0010] The first protective mechanism supports the shielding component and forms pressure-resistant protection, while the second protective mechanism forms rigid protection. The protection state is changed according to the drive component, and active protection is provided.

[0011] For example, the support component includes a mounting sleeve, which is fixedly mounted on both ends of the surface of the servo motor body. A toothed sleeve is rotatably connected to the outer side of the mounting sleeve, and a first mounting plate is fixedly mounted on the inner side of the toothed sleeve.

[0012] For example, the elastic component includes a mounting block fixedly mounted on the top of a first mounting plate, and a crossbar, a spring, and a damper are fixedly mounted on the inner side of the mounting block, with the spring located outside the crossbar and the damper located below the crossbar and the spring.

[0013] A support plate is fixedly installed at the inner end of the spring, the support plate is slidably connected to the outside of the crossbar, and a movable rod is rotatably connected to the top of the support plate.

[0014] For example, the shielding assembly includes a first connecting seat, which is rotatably connected to the top of the movable rod. A first arc-shaped plate is fixedly installed on the top of the first connecting seat, and a first rotating rod is rotatably connected to the outer side of the first arc-shaped plate. Side plates are fixedly installed on both sides of the bottom of the first arc-shaped plate.

[0015] For example, the connecting assembly includes a second mounting plate, which is fixedly mounted on the inner side of the toothed sleeve. A support column is fixedly mounted on the bottom of the second mounting plate, and a second connecting seat is fixedly mounted on the bottom end of the support column.

[0016] For example, the protective component includes a second arc-shaped plate, which is fixedly installed at the bottom of the second connecting seat. A second rotating rod is rotatably connected to the bottom of the second arc-shaped plate. Plate sleeves are fixedly installed on both sides of the top of the second arc-shaped plate. Through holes are opened on the outer sides of the plate sleeves and the side plates. The plate sleeves and the side plates are sleeved together.

[0017] For example, the drive assembly includes a motor, which is fixedly mounted at one end of the bottom of the servo motor body. The output shaft of the motor is keyed to a shaft, and a gear is fixedly mounted at one end of the shaft. The gear meshes with a toothed sleeve.

[0018] For example, the first heat dissipation mechanism includes a first protective shell, which is fixedly installed at one end of the servo motor body. A rear end shaft is fixedly installed at one end of the servo motor body. The rear end shaft is rotatably connected through the inside of the first protective shell. A key block is fixedly installed on the outer side of the rear end shaft. A first fan blade group is provided on the outer side of the rear end shaft. A keyway is opened on the inner sidewall of the first fan blade group. The key block is located inside the keyway. A first adapter groove is opened at one end of the rear end shaft.

[0019] For example, the cleaning mechanism includes a first mesh plate, which is bolted to one end of a first protective shell. A first adapter block is inserted into the first adapter slot. A fixing rod is fixedly installed at one end of the first adapter block. A second adapter slot is opened at one end of the fixing rod. Connecting plates are fixedly installed at both ends of the outer side of the fixing rod. A brush strip is bolted to the inner side of the connecting plate.

[0020] The blower mechanism includes a second adapter block inserted into a second adapter slot. A connecting shaft is fixedly installed at one end of the second adapter block. A second fan blade assembly is fixedly installed at the outer end of the connecting shaft. A sleeve is provided on the outer side of the second fan blade assembly. A second mesh plate is fixedly installed at one end of the sleeve. A connecting pipe is fixedly installed through the inside of the sleeve. A coiled tube is connected to one end of the connecting pipe. An exhaust hole is opened on one side of the coiled tube. A second protective shell is bolted to the outer side of one end of the servo motor body. A third mesh plate is fixedly installed at one end of the second protective shell.

[0021] A method for using an active protection servo motor includes the following steps:

[0022] S1: When the servo motor is under protection, when the top is subjected to force, it will first contact the first arc plate and several sets of first rotating rods set on its top. Since it is an arc rolling setting, when it is subjected to force for the first time, it will roll off the force due to rolling and arc setting, and at the same time, it will also exert downward pressure on it. At this time, the force transmission is directly from the first connecting seat to the moving rod to push the spring and damper, and the spring and damper constitute a damping spring shock absorber, thereby completing the impact reduction operation.

[0023] S2: When changing the protection state during the active protection process, the motor operates directly, driving the shaft rod through the output shaft and then driving the gear to rotate synchronously. The protection rotation during active protection is completed by the meshing of the gear and the tooth set on the toothed sleeve. At this time, the first arc plate will exchange positions with the second arc plate and the second rotating rod, changing from flexible protection to rigid protection, thus realizing the protection change during active protection.

[0024] S3: When discharging heat from the inside to the outside, the servo motor will drive the rear shaft at the rear end to rotate synchronously while it is working continuously. This will drive the first fan blade group on the outside to rotate synchronously and blow the heat generated inside to the outside to accelerate heat dissipation. At the same time, it will also drive the fixed rod installed at one end of the rear shaft, as well as several sets of connecting plates and brush strips to rotate together. During the rotation, the two sides of the first mesh plate will be cleaned simultaneously.

[0025] S4: When dissipating heat from the outside, the connecting shaft and the second fan blade group rotate synchronously during the rotation of the fixed rod. The second fan blade group blows the external air from the outside to the inside until it enters the sleeve. It is then transported to the coil tube through the connecting pipe and finally discharged through the exhaust hole, increasing the airflow speed outside the servo motor body. At the same time, it blows the heat dissipated by the servo motor body away from the servo motor body.

[0026] Compared with the prior art, the beneficial effects of the present invention are:

[0027] 1. This invention employs an active protection method to protect the servo motor through the coordinated arrangement of the first protective mechanism, the shielding component, the second protective mechanism, and the drive component, thereby improving the protection of the servo motor. The elastic and rigid protection can be switched through a rotatable adjustment mechanism. The coordination between the first protective mechanism and the shielding component achieves elastic and damped impact and pressure resistance, while the second protective mechanism can directly achieve rigid protection, thus meeting different usage scenarios. The active protection is switched through the power output of the drive component during the switching process, and it can be used not only for top protection but also directly for protection on both sides.

[0028] 2. Through the coordinated arrangement of the first heat dissipation mechanism, the cleaning mechanism, and the blower mechanism, this invention achieves the advantages of accelerated heat dissipation and tail-end cleaning, thereby improving the stability and sustainable operation of the servo motor. The first heat dissipation mechanism mainly targets the accelerated discharge of heat from the inside to the outside of the tail end, while the blower mechanism facilitates the diversion of external gas and directs it towards the outside of the servo motor, thereby accelerating the flow rate outside the servo motor and blowing away the heat generated by the servo motor, ensuring that the surrounding heat does not continue to increase, thus improving the heat dissipation effect and efficiency, while also protecting the servo motor.

[0029] Other features and advantages of the invention will be set forth in the following description, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of the invention may be realized and obtained by means of the structures pointed out in the description and the drawings. Attached Figure Description

[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] This invention provides an active protection servo motor and its usage method, including a servo motor body 1;

[0043] The top of the servo motor body 1 is provided with a first protective mechanism 2 for external protection, the bottom of the servo motor body 1 is provided with a second protective mechanism 4 for external protection, the top of the first protective mechanism 2 is provided with a shielding component 3 for protection, the bottom of the servo motor body 1 is provided with a drive component 5 for switching active protection mode, one end of the servo motor body 1 is provided with a first heat dissipation mechanism 6 for external heat dissipation, one end of the first heat dissipation mechanism 6 is provided with a cleaning mechanism 7 for end treatment, and one end of the cleaning mechanism 7 is provided with a blower mechanism 8 for external heat dissipation.

[0044] The first protective mechanism 2 includes a support component and an elastic component. The support component is located on the outside of the servo motor body 1, and the elastic component is located on the top of the support component.

[0045] The combination of support components and elastic components can form elastic damping support and shock and pressure resistant operation;

[0046] The second protective mechanism 4 includes a connecting component and a protective component. The connecting component is located inside the supporting component, and the protective component is located outside the connecting component.

[0047] The cooperation between the connecting components and the protective components enables force receiving and transmission operations, and the impact and pressure can be reduced by rolling force relief.

[0048] The first protective mechanism 2 supports the shielding component 3 and forms pressure-resistant protection, while the second protective mechanism 4 forms rigid protection. The protection state is changed according to the drive component 5, and active protection is provided.

[0049] Preferred;

[0050] like Figure 3 As shown, the support assembly includes a mounting sleeve 21, which is fixedly installed on both ends of the surface of the servo motor body 1. A toothed sleeve 22 is rotatably connected to the outer side of the mounting sleeve 21, and a first mounting plate 23 is fixedly installed on the inner side of the toothed sleeve 22, thus realizing the rotatable connection and supporting the inner components.

[0051] like Figure 3As shown, the elastic component includes a mounting block 24, which is fixedly mounted on the top of the first mounting plate 23. A crossbar 25, a spring 28, and a damper 29 are fixedly mounted on the inner side of the mounting block 24. The spring 28 is located on the outer side of the crossbar 25, and the damper 29 is located below the crossbar 25 and the spring 28. The elastic damping method can reduce the impact and pressure generated on the servo motor and form protection.

[0052] A support plate 26 is fixedly installed on the inner end of the spring 28. The support plate 26 is slidably connected to the outside of the crossbar 25. The top of the support plate 26 is rotatably connected to a movable rod 27, which will be transmitted downward according to the generated impact or pressure, and will reduce the impact or pressure by pushing.

[0053] further;

[0054] like Figure 3 As shown, the shielding assembly 3 includes a first connecting seat 34, which is rotatably connected to the top of the movable rod 27. A first arc-shaped plate 31 is fixedly installed on the top of the first connecting seat 34. A first rotating rod 32 is rotatably connected to the outer side of the first arc-shaped plate 31. Side plates 33 are fixedly installed on both sides of the bottom of the first arc-shaped plate 31, which can directly contact the impact or pressure and change the direction of the object that generates the impact or pressure. By rolling and the arc-shaped setting, the object is deflected, thereby performing preliminary protection work.

[0055] As mentioned above, flexible protection is achieved. When working, objects that generate impact or pressure will directly contact the first rotating rod 32. Since the first rotating rod 32 is rotatably connected to the top of the first arc plate 31 and is designed based on the combination of rotation and arc, its direction can be changed at the moment of contact, thereby reducing the impact or pressure on the components below and achieving initial protection.

[0056] When the remaining impact or pressure continues to be transmitted downward, it will directly press down the first arc plate 31 and the first connecting seat 34, and the first connecting seat 34 will press down the movable rod 27. When the angle of the movable rod 27 changes, it will simultaneously push the spring 28 and the damper 29 outward. The cooperation of the spring 28 and the damper 29 forms a damping elastic protection. The cooperation between the two can form the effect of a shock absorber in the prior art, or similar technical means can be directly used, such as the damping spring shock absorber in the prior art as a replacement.

[0057] Going a step further;

[0058] like Figure 3As shown, the connecting assembly includes a second mounting plate 41, which is fixedly installed on the inner side of the toothed sleeve 22. A support column 42 is fixedly installed on the bottom of the second mounting plate 41, and a second connecting seat 43 is fixedly installed on the bottom end of the support column 42, thereby achieving support and fixing of the required connecting parts.

[0059] like Figure 3 As shown, the protective component includes a second arc-shaped plate 44, which is fixedly installed at the bottom of the second connecting seat 43. A second rotating rod 46 is rotatably connected to the bottom of the second arc-shaped plate 44. Plate sleeves 45 are fixedly installed on both sides of the top of the second arc-shaped plate 44. Through holes 47 are opened on the outer side of both the plate sleeves 45 and the side plate 33. The plate sleeves 45 and the side plate 33 are sleeved together. By directly fixing the connection, the rigid support and protection effects are achieved.

[0060] When the above components are moved to the top or the outside, rigid protection can be achieved. Depending on the required protection method, when under force, the second rotating rod 46 is directly pre-loaded. As mentioned above, this can deflect the generated impact and pressure, reducing damage to the servo motor. Then, the remaining force is directly borne by the second arc plate 44, the second mounting plate 41, the support column 42, and the second connecting seat 43, avoiding damage to the servo motor.

[0061] It is worth explaining;

[0062] like Figure 4 As shown, the drive assembly 5 includes a motor 51, which is fixedly installed at one end of the bottom of the servo motor body 1. The output shaft of the motor 51 is keyed to a shaft 52, and a gear 53 is fixedly installed at one end of the shaft 52. The gear 53 meshes with the toothed sleeve 22, realizing the power output operation when the servo motor is actively switched to the protection state, so as to meet the needs of people's actual use.

[0063] During the replacement, as shown in the figure, the top of the servo motor is elastically protected. When rigid protection is required, the motor 51 drives the gear 53 to rotate directly through the shaft 52. The gear 53 will mesh and drive the toothed sleeve 22 to rotate on the outside of the mounting sleeve 21. Ventilation holes are provided on the outside of the mounting sleeve 21 to avoid blocking the airflow during the rotation and replacement, and to ensure subsequent external auxiliary heat dissipation. Continue to rotate until the second protective mechanism 4 is on top to complete the replacement operation.

[0064] The protection method is not limited to the top protection mentioned above; it can also be rotated to protect the sides. It can be adjusted according to actual needs, and the angle and direction of protection can be changed with the force of rotation until it is in the desired position.

[0065] in;

[0066] like Figure 5 As shown, the first heat dissipation mechanism 6 includes a first protective shell 61, which is fixedly installed at one end of the servo motor body 1. A rear end shaft 62 is fixedly installed at one end of the servo motor body 1. The rear end shaft 62 is rotatably connected through the inside of the first protective shell 61. A key block 63 is fixedly installed on the outside of the rear end shaft 62. A first fan blade group 64 is provided on the outside of the rear end shaft 62. A keyway 65 is provided on the inner sidewall of the first fan blade group 64. The key block 63 is located inside the keyway 65. A first adapter groove 66 is provided at one end of the rear end shaft 62.

[0067] The servo motor has a front shaft and a rear shaft 62. The front shaft is usually connected to the required components and drives them to rotate. The rear shaft 62 is usually equipped with auxiliary components, such as cooling fans. The rotation of the rear shaft 62 can drive the first fan blade group 64 to rotate and dissipate the heat generated inside from the rear end to the outside.

[0068] During operation, the first fan blade assembly 64 can be sleeved on the outside of the rear shaft 62 by sliding the key block 63 and the keyway 65, and then fixed by flange connection. When it rotates, it can drive the first fan blade assembly 64 to rotate synchronously and discharge the internal heat from the inside to the outside.

[0069] at last;

[0070] like Figure 9 and 10 As shown, the cleaning mechanism 7 includes a first mesh plate 76, which is bolted to one end of the first protective shell 61. A first adapter block 71 is inserted into the inside of the first adapter groove 66. A fixing rod 72 is fixedly installed at one end of the first adapter block 71. A second adapter groove 73 is opened at one end of the fixing rod 72. A connecting plate 74 is fixedly installed at both ends of the outer side of the fixing rod 72. A brush strip 75 is bolted to the inner side of the connecting plate 74.

[0071] It can clean both the inner and outer sides of the first screen plate 76 at the same time, preventing dust and debris from entering its working space. The dust from the grabbing brush will be scattered in the air when it is cleaned, and blown to the outside according to the first fan blade group 64 mentioned above. After the first adapter block 71 is inserted into the first adapter groove 66, the fixing rod 72 is bolted to the rear shaft 62 to form a fixed position. During its rotation, it can synchronously drive the inner and outer connecting plates 74 and brush strips 75 to rotate synchronously to complete the rotating grabbing brush cleaning operation.

[0072] Based on the above, after the first adapter block 71 is inserted into the first adapter slot 66, it can be fixed without bolts. When the fixing rod 72 and the first mesh plate 76 are in a through-rotational connection state, the fixing of the first mesh plate 76 can ensure the fixation of the position of the fixing rod 72.

[0073] like Figure 7 and8 As shown, the blower mechanism 8 includes a second adapter block 81, which is inserted into the second adapter slot 73. A connecting shaft 82 is fixedly installed at one end of the second adapter block 81, and a second fan blade assembly 83 is fixedly installed at the outer end of the connecting shaft 82. A sleeve 84 is provided on the outer side of the second fan blade assembly 83, and a second mesh plate 85 is fixedly installed at one end of the sleeve 84. A connecting pipe 86 is fixedly installed through the inside of the sleeve 84, and a coiled tube 87 is connected to one end of the connecting pipe 86. An exhaust hole 88 is opened on one side of the coiled tube 87. A second protective shell 89 is bolted to the outer side of one end of the servo motor body 1, and a third mesh plate 810 is fixedly installed at one end of the second protective shell 89.

[0074] The blower mechanism 8 directs external air to the outside of the servo motor, thereby increasing the airflow around the servo motor and preventing heat buildup. Continuous blowing ensures continuous airflow and removes heat, thus improving heat dissipation efficiency and protecting the servo motor.

[0075] During operation, based on the above, the second adapter block 81 is directly inserted into the interior of the second adapter slot 73, and then connected and fixed through the flange. When the fixing rod 72 rotates, it can drive the second fan blade group 83 to rotate synchronously, thereby guiding the external airflow into the sleeve 84, and then into the connecting pipe 86 and discharged into the coil pipe 87. Finally, it is discharged through the exhaust hole 88. When discharged, it is arranged in a ring and blown towards the outside of the servo motor, increasing the airflow speed of the surrounding air, thereby removing heat and improving heat dissipation efficiency, and forming a protective operation.

[0076] A method for using an active protection servo motor includes the following steps:

[0077] S1: When the servo motor is protected, when the top is subjected to force, it will first contact the first arc plate 31 and several sets of first rotating rods 32 set on its top. Since it is an arc rolling setting, when it is subjected to force for the first time, it will roll off the force due to rolling and arc setting, and at the same time, it will also exert downward pressure on it. At this time, the force transmission is directly from the first connecting seat 34 through the movable rod 27 to push the spring 28 and the damper 29, and the spring 28 and the damper 29 constitute a damping spring shock absorber, thereby completing the impact reduction operation.

[0078] S2: When changing the protection state during the active protection process, the motor 51 operates directly, driving the shaft 52 through the output shaft and simultaneously driving the gear 53 to rotate synchronously. The active protection rotation is completed by the meshing of the gear 53 with the toothed sleeve 22. At this time, the first arc plate 31 will exchange positions with the second arc plate 44 and the second rotating rod 46, changing from flexible protection to rigid protection, thus realizing the protection change during active protection.

[0079] S3: When discharging heat from the inside to the outside, the servo motor will drive the rear shaft 62 at the rear end to rotate together while it is working continuously. This will drive the first fan blade group 64 on the outside to rotate synchronously and blow the heat generated inside to the outside to accelerate heat dissipation. At the same time, it will also drive the fixed rod 72 installed at one end of the rear shaft 62, as well as several sets of connecting plates 74 and brush strips 75 to rotate together. During the rotation, the two sides of the first mesh plate 76 will be cleaned simultaneously.

[0080] S4: When dissipating heat from the outside, the connecting shaft 82 and the second fan blade group 83 are rotated synchronously during the rotation of the fixed rod 72. The second fan blade group 83 blows the external air from the outside to the inside until it enters the sleeve 84 and is transported to the coil tube 87 through the connecting pipe 86. Finally, it is discharged through the exhaust hole 88 and increases the airflow speed outside the servo motor body 1. At the same time, it blows the heat dissipated by the servo motor body 1 away from the servo motor body 1.

[0081] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.

8. A method of using an active protection servo motor, applied to the active protection servo motor according to any one of claims 1-7, characterized in that, Includes the following steps: S1: When the servo motor is protected, when the top is subjected to force, it will first contact the first arc plate (31) and several sets of first rotating rods (32) set on its top. Since it is set in an arc rolling configuration, when it is subjected to force for the first time, it will roll off the force due to rolling and the arc setting, and at the same time, it will also cause downward pressure. At this time, the force transmission is directly from the first connecting seat (34) through the movable rod (27) to push the spring (28) and the damper (29). The spring (28) and the damper (29) constitute a damping spring shock absorber, thereby completing the action of reducing the impact force. S2: When changing the protection state during the active protection process, the motor (51) operates directly. The output shaft drives the shaft (52) and drives the gear (53) to rotate synchronously. The active protection rotation is completed by the meshing of the gear (53) and the toothed sleeve (22). At this time, the first arc plate (31) will be swapped with the second arc plate (44) and the second rotating rod (46), changing from flexible protection to rigid protection, thus realizing the protection change during active protection. S3: When heat is discharged from the inside to the outside, the servo motor will drive the rear shaft (62) at the rear end to rotate together while it is working continuously, thereby driving the first fan blade group (64) on the outside to rotate synchronously, and blowing the heat generated inside to the outside to accelerate heat dissipation. At the same time, it will also drive the fixed rod (72) installed at one end of the rear shaft (62), as well as several sets of connecting plates (74) and brush strips (75) to rotate together, and clean both sides of the first mesh plate (76) synchronously during the rotation. S4: When dissipating heat from the outside, the connecting shaft (82) and the second fan blade group (83) are rotated synchronously during the rotation of the fixed rod (72). The second fan blade group (83) blows the external gas from the outside to the inside until it enters the sleeve (84) and is transported to the coil tube (87) through the connecting pipe (86). Finally, it is discharged through the exhaust hole (88) and increases the air flow rate outside the servo motor body (1). At the same time, it blows the heat dissipated by the servo motor body (1) away from the servo motor body (1).
