Description

Technical Field

[0001] The invention belongs to the technical field of servo motor protection, and in particular relates to a protection box for a servo motor. Background Art

[0002] Servo motors can control speed and position accuracy very accurately. They can convert voltage signals into torque and speed to drive the controlled object. The rotor speed of the 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 small electromechanical time constant and high linearity. They can convert the received electrical signals into angular displacement or angular velocity output on the motor shaft. They are divided into two categories: DC and AC servo motors. Their main characteristics are that there is no self-rotation when the signal voltage is zero, and the speed decreases uniformly with the increase of torque. Servo motors, as precision drive equipment, are often used in automation equipment, robots, precision instruments and other fields. They need to work stably in various complex environments, including but not limited to environments with dust, moisture, oil, and corrosive substances. Therefore, designing a suitable protective box is crucial to ensure the long-term stability of the servo motor and extend its service life.

[0003] However, during the use of the protective box on the existing servo motor, the servo motor will heat up after working for a long time in the box, and the heat dissipation effect of the servo motor is not good. For example, only water cooling is performed separately, and the speed of water cooling is slow, which will lead to poor heat dissipation effect of the servo motor after heat dissipation; the rotating end of the servo motor will jump when it is rotating, and the rotating end cannot be limited. Summary of the invention

[0004] The embodiment of the present invention provides a protection box for a servo motor to solve the problems in the prior art.

[0006] The present invention adopts the cooperation of multiple heat dissipation structures and limit structures to achieve all-round protection for the servo motor. It can not only effectively reduce the temperature of the motor during use and avoid working failure caused by overheating, but also ensure the safety and stability of the motor during operation.

[0007] A further technical solution is that the first heat dissipation structure includes a circulation pump, a circulation box, a refrigeration cylinder and a refrigeration pipe, the circulation box is located at the bottom of the protective box, the refrigeration cylinder wraps the motor body and the refrigeration cylinder is connected to the protective box, the refrigeration cylinder is a hollow structure, the refrigeration pipe is located in the refrigeration cylinder, the two ends of the refrigeration pipe are respectively connected to the circulation box, the circulation pump is located in the circulation box and connected to one end of the refrigeration pipe, and the circulation box is provided with a refrigeration plate for cooling water.

[0008] According to a further technical solution, the refrigeration tube is a spiral structure.

[0009] A further technical solution is that the second heat dissipation structure includes a bubbler and a heat dissipation cylinder, the bubbler is located in the protection box and below the refrigeration cylinder, the bubbler is connected to the protection box, the heat dissipation cylinder is vertically arranged above the refrigeration cylinder and the top of the heat dissipation cylinder is flush with the protection box, and the top of the heat dissipation cylinder is provided with a plurality of air outlets. The heat in the refrigerant is quickly discharged to the outside, and the refrigeration pipe can also be cooled, so that the heat dissipation effect is better during the use of the motor body, which is convenient for the subsequent use of the motor body.

[0010] According to a further technical solution, a bearing is provided between the rotating end of the motor body and the protective box, and the rotating end rotates on the bearing.

[0011] According to a further technical solution, an oil seal box is provided on the outer wall of the protection box at the position of the bearing, and an oil filling hole is provided on the oil seal box.

[0012] A further technical solution is that the protective limit structure includes a limit screw, which is threadedly connected to the protective box at the bearing, and is vertically arranged. The bottom of the limit screw is provided with a limit half ring rotatably connected thereto, and the protective box is provided with a slide groove for the limit half ring to move up and down, and the rotating end of the motor body rotates on the limit half ring.

[0013] According to a further technical solution, a sound-absorbing sponge is provided in the installation shell.

[0014] According to a further technical solution, a rear wall of the protection box is provided with heat dissipation holes.

[0015] At least one of the above technical solutions adopted in the embodiments of the present invention can achieve the following beneficial effects:

[0016] Firstly, when the protective box of the present invention is protecting the servo motor, the first heat dissipation structure can be used to water-cool the motor body.

DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the specific embodiments of the present invention and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0028] The technical solutions provided by various embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0029] Reference Figures 1 to 6 As shown, an embodiment of the present invention provides a protective box for a servo motor, including a motor body 1 and a protective box 2, wherein the motor body 1 is located in the protective box 2, a rotating end 11 is provided on the motor body 1, the rotating end 11 extends to the outside of the protective box 2 and the rotating end 11 is rotatably connected to the protective box 2, a mounting shell 21 is provided in the protective box 2, a first heat dissipation structure 3 and a second heat dissipation structure 4 for dissipating heat from the motor body 1 are provided in the mounting shell 21, the first heat dissipation structure 3 is arranged around the motor body 1, the second heat dissipation structure 4 is located on the first heat dissipation structure 3, the second heat dissipation structure 4 extends to the outside of the top of the protective box 2, and a protective limiting structure 5 is also provided on the protective box 2 at the rotating end 11, and the protective limiting structure 5 is slidably matched with the protective box 2. The protective box 2 is usually made of corrosion-resistant, high-strength materials, such as stainless steel, aluminum alloy, etc., to resist external physical and chemical erosion.

[0030] When the protective box 2 is protecting the servo motor, the first heat dissipation structure 3 can be used to perform water cooling on the motor body 1. During the water cooling process, the second heat dissipation structure 4 can cooperate with the first heat dissipation structure 3 to better dissipate the heat of the motor body 1, so that the heat dissipation effect of the motor body 1 is better when it is working, and there will be no heating phenomenon that causes the heat dissipation motor body 1 to not work. During use, the protective limiting structure 5 can be used to limit the rotating end 11 on the motor body 1, so that when the rotating end 11 of the motor body 1 shakes or jumps during operation, the position of the rotating end 11 will not be offset and the motor body 1 will not be damaged. Limiting the rotation of the rotating end 11 can ensure the safety and stability of the motor body 1 during operation.

[0031] Specifically, the first heat dissipation structure 3 includes a circulation pump 31, a circulation box 32, a refrigeration cylinder 33 and a refrigeration pipe 34. The circulation box 32 is located at the bottom of the protective box 2. The refrigeration cylinder 33 wraps the motor body 1 and is connected to the protective box 2. The refrigeration cylinder 33 is a hollow structure. The refrigeration pipe 34 is located in the refrigeration cylinder 33. Both ends of the refrigeration pipe 34 are respectively connected to the circulation box 32. The circulation pump 31 is located in the circulation box 32 and is connected to one end of the refrigeration pipe 34. A refrigeration plate for cooling water is provided in the circulation box 32.

[0032] The refrigeration plate can cool the water in the circulation box 32. After the water is cooled, the cold water can be transported to the refrigeration pipe 34 through the circulation pump 31. The motor body 1 is surrounded by the refrigeration pipe 34 to quickly dissipate heat and cool the motor body 1. During the heat dissipation process, the heat is circulated to ensure a better heat dissipation effect.

[0033] Specifically, the refrigeration pipe 34 is a spiral structure; the refrigeration pipe 34 with a spiral structure can increase the heat dissipation area and heat dissipation time, so that the refrigeration pipe 34 has a good heat dissipation effect when dissipating heat.

[0034] Specifically, the second heat dissipation structure 4 includes a bubbler 41 and a heat dissipation tube 42. The bubbler 41 is located in the protection box 2 and below the refrigeration tube 33. The bubbler 41 is connected to the protection box 2. The heat dissipation tube 42 is vertically arranged above the refrigeration tube 33 and the top of the heat dissipation tube 42 is flush with the protection box 2. The top of the heat dissipation tube 42 is provided with a plurality of air outlets 43. There is refrigerant in the heat dissipation tube 42, and the heat dissipation tube 42 can be used for heat dissipation.

[0035] When the refrigerant in the heat sink 42 is dissipating heat, the bubbler 41 continuously generates bubbles into the heat sink 42. The bubbles will drive the heat generated by the refrigerant in the heat sink 42 upward in the process of floating upward. The hot air will be discharged from the air outlet 43 on the heat sink 42 in the process of the bubbles being discharged outward. The bubbler 41 continuously generates bubbles during use, so that the bubbles diffuse in the refrigerant in the heat sink 42, and the heat in the refrigerant is quickly discharged outward. The cooling tube 34 can also be cooled, so that the heat dissipation effect is better during the use of the motor body 1, which is convenient for the subsequent use of the motor body 1.

[0036] When the motor body 1 is cooled, double cooling can be performed to ensure that the cooling effect is better, the heat generated by the servo motor can be effectively dissipated, and the motor can be guaranteed to run at a suitable temperature.

[0037] Specifically, a bearing 12 is provided between the rotating end 11 of the motor body 1 and the protective box 2 , and the rotating end 11 rotates on the bearing 12 .

[0038] Specifically, an oil seal box 22 is provided on the outer wall of the protective box 2 at the position of the bearing 12, and an oil filling hole 23 is provided on the oil seal box 22; the oil seal box 22 can seal and protect the bearing 12 to prevent impurities and debris from flying into the oil seal during long-term use or special operating environments, thereby affecting the rotation of the rotating end 11 of the motor body 1 on the oil seal. The oil filling hole 23 can lubricate the oil seal during use so that there is sufficient lubricating oil on the oil seal for lubrication.

[0039] Specifically, the protective limiting structure 5 includes a limiting screw 51, which is threadedly connected to the protective box 2 at the bearing 12. The limiting screw 51 is vertically arranged, and the bottom of the limiting screw 51 is provided with a limiting semi-ring 52 rotatably connected thereto. The protective box 2 is provided with a sliding groove for the limiting semi-ring 52 to move up and down, and the rotating end 11 of the motor body 1 rotates on the limiting semi-ring 52.

[0040] When limiting the rotating end 11 of the limit motor, the limiting screw 51 is rotated to drive the position of the limiting half ring 52 to move downward in the slide groove, and the position of the limiting half ring 52 is moved downward to the rotating end 11 of the limit motor to resist the rotating end 11, so as to prevent the rotating end 11 from shaking or jumping during the rotation process, affecting the operation of the motor body 1, and after long-term use, the position of the bearing 12 and the rotating end 11 becomes eccentric. After long-term use, the limiting screw 51 can be rotated so that the limiting half ring 52 limits the rotating end 11, which can ensure the safety and stability of the motor body 1 during operation.

[0041] Specifically, a sound-absorbing sponge 6 is provided in the mounting shell 21; during use, the sound-absorbing sponge 6 can firstly absorb and reduce the noise and murmur generated by the motor body 1 during operation, and secondly eliminate the shaking and vibration generated by the motor body 1, thereby preventing the shaking generated by the motor body 1 during operation from affecting the use.

[0042] Specifically, the rear wall of the protection box 2 is provided with heat dissipation holes 24; the heat dissipation holes 24 can discharge the heat generated by the motor body 1 to the outside, so that the heat dissipation effect of the motor body 1 is better when dissipating heat.

[0043] A protective box 2 for a servo motor, in particular, provides a technical solution that can improve the heat dissipation effect of the motor and prevent the position deviation of the rotating end 11 when protecting the servo motor. Specifically, the protective box 2 includes a protective shell and a heat dissipation system, wherein a servo motor is embedded in the protective shell. A plurality of heat dissipation structures, such as a first heat dissipation structure 3 and a second heat dissipation structure 4, are arranged inside the protective shell for water cooling the servo motor. At the same time, a plurality of limiting structures, such as a protective limiting structure 5, are also arranged inside the protective shell for limiting the rotating end 11 of the motor body 1.

[0044] In actual applications, the motor body 1 inside the protective box 2 will generate heat due to factors such as load and temperature, thereby affecting its normal operation. In order to solve this problem, the present invention designs a set of efficient heat dissipation systems, including multiple heat dissipation structures, such as a first heat dissipation structure 3 and a second heat dissipation structure 4. These heat dissipation structures can effectively dissipate the heat generated by the servo motor to ensure that the motor runs at a suitable temperature. At the same time, in order to better protect the servo motor, a limiting structure, such as a protective limiting structure 5, is also provided inside the protective shell of the present invention. These limiting structures can effectively limit the rotating end 11 of the motor body 1 to prevent the rotating end 11 from being displaced due to shaking or jumping during operation, thereby avoiding damage to the motor.

[0045] In the protective box 2 and the working method thereof of the present invention, multiple heat dissipation structures and limit structures are used to cooperate with each other to achieve all-round protection of the servo motor. Not only can the temperature of the motor during use be effectively reduced to avoid failure caused by overheating, but also the safety and stability of the motor during operation can be ensured. Therefore, the present invention can provide users with an efficient and reliable protective box 2 and a working method thereof, which are particularly suitable for application scenarios where the servo motor needs to be protected.
