Description

Technical Field

[0001] The present invention relates to the technical field of servo motor equipment, and in particular to a servo motor protection structure and a use method thereof. Background Art

[0002] The protective structure of the servo motor is mainly used to protect the internal components of the motor from external environmental factors such as dust, moisture and mechanical shock. These structures usually include corrosion-resistant housing, sealing design and heat dissipation system. By effectively preventing pollutants from entering the motor, the motor can be ensured to operate normally under high loads and extreme temperatures, thereby improving the reliability and service life of the motor.

[0003] The servo motor needs to be cooled during its use. During the long heat dissipation process, the outside air will carry a small amount of fine dust into the motor casing.

[0009] Further, a heat dissipation mechanism is arranged in the housing, the heat dissipation mechanism includes a U-shaped circular box fixedly installed on the inner wall of the housing, the rotating shaft penetrates through the U-shaped circular box and is rotatably connected with the U-shaped circular box, a plurality of heat dissipation fan blades are fixedly installed on the outer wall of the rotating shaft, and a plurality of air inlet holes are opened on the front of the housing.

[0010] Further, an arc-shaped hollow block is fixedly installed on the back of the housing, an arc-shaped plate is fixedly installed on the top inner wall of the arc-shaped hollow block, a telescopic spring is fixedly installed on the back of the arc-shaped plate, and an arc-shaped sealing plate is fixedly installed at the end of the telescopic spring, and the arc-shaped sealing plate is slidably connected with the arc-shaped hollow block.

[0011] Further, two strip-shaped limiting sliding grooves are opened on the inner wall of the arc-shaped hollow block, and L-shaped limiting plates are respectively slidably installed in the two strip-shaped limiting sliding grooves, and the ends of the two L-shaped limiting plates are fixedly connected with the arc-shaped sealing plate.

[0012] Further, two transmission mechanisms are arranged in the hollow connecting block, the transmission mechanisms include transmission springs fixedly installed on the inner walls of the hollow connecting blocks, the ends of the trapezoidal tooth plates extend into the hollow connecting blocks and are fixedly connected with the transmission springs, and an L-shaped arc plate is fixedly installed on the outer wall of the housing.

[0013] Further, a plurality of rotating rods are rotatably installed on the front inner wall of the hollow connecting block, a plurality of teeth are respectively fixedly installed on the outer walls of the plurality of rotating rods, the plurality of teeth are all meshed with the trapezoidal tooth plates, the ends of the plurality of rotating rods all extend outside the hollow connecting block, and brushes are respectively fixedly installed at the ends of the plurality of rotating rods, and the plurality of brushes are all in contact with the housing.

[0014] Furthermore, the method of the servo motor protection structure comprises the following steps:

[0015] S1: When in use, start the servo motor, the servo motor drives the rotating shaft to rotate, the rotating shaft drives the hollow connecting block to rotate, the hollow connecting block drives the trapezoidal tooth plate to rotate, the trapezoidal tooth plate will contact the trapezoidal push plate during the rotation process, the trapezoidal push plate will move in the direction close to the servo motor under the action of its inclined surface, the trapezoidal push plate will push the mounting plate to move, the mounting plate drives the fixed sleeve to slide, the fixed sleeve drives the fixed plate to move at the same time, at this time, since the fixed plate moves in the direction away from the trapezoidal push plate, the reset spring will be stretched and deformed, and the cleaning sleeve will scrape the dust falling on the heat sink to the inner wall of the shell when moving, when the trapezoidal tooth plate leaves the trapezoidal push plate, the trapezoidal push plate will be reset under the elastic force of the reset spring, so the cleaning sleeve will form a reciprocating motion, and the dust falling on the surface of the heat sink will be cleaned off during the reciprocating motion of the cleaning sleeve;

[0016] S2: During the rotation of the shaft, several heat dissipation fan blades will be driven to rotate. The rotation of the heat dissipation fan blades will generate a suction force, which will suck the outside air into the shell through the air inlet. At the same time, dust particles in the air will adhere to the surface of the air inlet and cause blockage. At this time, the trapezoidal tooth plate will contact the L-shaped arc plate during the rotation. Under the action of the inclined surface of the trapezoidal tooth plate, the trapezoidal tooth plate will slide into the hollow connecting block. The trapezoidal tooth plate will contact several teeth, and the several teeth will drive several rotating rods to rotate. The rotating rod will drive several brushes to rotate. Since the trapezoidal tooth plate rotates around the shaft, the brushes will clean several air inlet holes on the front of the shell when they rotate.

[0017] S3: As more and more gas enters the shell, the air pressure in the shell increases continuously, and the gas will enter the arc-shaped hollow block through the arc-shaped gap between the arc-shaped plate and the arc-shaped hollow block. The air will push the arc-shaped sealing plate to move away from the shell. At this time, the telescopic spring will be stretched and deformed, and the arc-shaped sealing plate will leave the arc-shaped hollow block. In the process of the arc-shaped hollow block leaving, the L-shaped limit plate will be driven to move at the same time. The L-shaped limit plate will slide along the track of the strip limit slide groove to play a limiting role. When the arc-shaped sealing plate leaves the arc-shaped hollow block, the air will be blown out from the gap between the arc-shaped sealing plate and the arc-shaped hollow block. In the process of the air being discharged from the shell, the fine dust that falls on the inner wall of the shell will be taken away together;

[0018] S4: After the servo motor stops running, heat dissipation air will not be injected into the housing. As the air pressure in the housing decreases, the arc-shaped sealing plate will return to the arc-shaped hollow block under the elastic force of the telescopic spring and the limiting action of the L-shaped limiting plate. At this time, the arc-shaped hollow block returns to a sealed state, preventing external dust from entering the housing through the gap between the arc-shaped hollow block and the arc-shaped sealing plate when the servo motor is not in use.

[0019] The present invention has the following beneficial effects:

[0020] (1) The present invention provides a servo motor protection structure. When the servo motor is started, the servo motor drives the rotating shaft to rotate, the rotating shaft drives the hollow connecting block to rotate, the hollow connecting block drives the trapezoidal tooth plate to rotate, the trapezoidal tooth plate will contact the trapezoidal push plate during the rotation process, the trapezoidal push plate will move in the direction close to the servo motor under the action of its inclined surface, the trapezoidal push plate will push the mounting plate to move, the mounting plate drives the fixed sleeve to slide, the fixed sleeve drives the fixed plate to move at the same time, at this time, since the fixed plate moves in the direction away from the trapezoidal push plate, the reset spring will be stretched and deformed, the cleaning sleeve will scrape the dust falling on the heat sink to the inner wall of the shell when moving, when the trapezoidal tooth plate leaves the trapezoidal push plate, the trapezoidal push plate will reset under the elastic force of the reset spring, so the cleaning sleeve will form a reciprocating movement, and the dust falling on the surface of the heat sink will be cleaned off during the reciprocating movement of the cleaning sleeve, so as to prevent the dust from affecting the heat dissipation effect of the heat sink, resulting in the servo motor not being able to dissipate heat normally and generating high temperature, thereby shortening the service life of the servo motor;

[0021] (2) A servo motor protection structure of the present invention drives a plurality of heat dissipation fan blades to rotate during the rotation of the rotating shaft. The rotation of the heat dissipation fan blades generates a suction force, which draws the outside air into the housing through the air inlet. At the same time, dust particles in the air adhere to the surface of the air inlet and cause blockage. At this time, the trapezoidal tooth plate contacts the L-shaped arc plate during the rotation. Under the action of the inclined surface of the trapezoidal tooth plate, the trapezoidal tooth plate slides into the hollow connecting block. The trapezoidal tooth plate contacts a plurality of teeth, which drive a plurality of rotating rods to rotate. The rotating rod drives a plurality of brushes to rotate. Since the trapezoidal tooth plate rotates around the rotating shaft, the brushes clean the plurality of air inlet holes on the front of the housing when they rotate, thereby improving the cleanliness of the surface of the air inlet holes and effectively preventing the air inlet holes from being blocked by dust.

[0022] (3) A servo motor protection structure of the present invention, as more and more gas enters the shell, the air pressure in the shell continues to increase, and the gas will enter the arc-shaped hollow block through the arc-shaped gap between the arc-shaped plate and the arc-shaped hollow block. The air will push the arc-shaped sealing plate to move away from the shell. At this time, the telescopic spring will be stretched and deformed, and the arc-shaped sealing plate will leave the arc-shaped hollow block. In the process of the arc-shaped hollow block leaving, it will also drive the L-shaped limit plate to move. The L-shaped limit plate will slide along the track of the strip limit slide groove to play a limiting role. When the arc-shaped sealing plate leaves the arc-shaped hollow block, the air will be blown out from the gap between the arc-shaped sealing plate and the arc-shaped hollow block. In the process of air being discharged from the shell, the fine dust that falls on the inner wall of the shell will be taken away together, ensuring that the dust in the shell can be effectively cleaned to prevent the dust from affecting the normal operation of the servo motor;

[0023] (4) A servo motor protection structure of the present invention does not inject heat dissipating air into the housing after the servo motor stops running. As the air pressure in the housing decreases, the arc-shaped sealing plate returns to the arc-shaped hollow block under the elastic force of the telescopic spring and the limiting action of the L-shaped limiting plate. At this time, the arc-shaped hollow block resumes its sealing state, preventing external dust from entering the housing through the gap between the arc-shaped hollow block and the arc-shaped sealing plate when the servo motor is not in use, thereby further reducing the possibility of dust entering the housing.

[0024] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0038] Please refer to Figure 1 - Fig. 9 As shown in the figure, the present invention is a protection structure for a servo motor, including an outer shell 1, a fixed sleeve 2 fixedly installed inside the outer shell 1, a servo motor 3 fixedly installed inside the fixed sleeve 2, and a plurality of heat dissipation plates 4 fixedly installed on the outer wall of the fixed sleeve 2. It further includes:

[0039] A dust removal mechanism 5, which includes two strip-shaped sliding grooves 501 opened on the fixed sleeve 2, a cleaning sleeve 502 slidably sleeved on the fixed sleeve 2, the cleaning sleeve 502 is slidably connected to the two strip-shaped sliding grooves 501, the cleaning sleeve 502 is in contact with a plurality of heat dissipation plates 4, a mounting plate 503 is fixedly installed on the outer wall of the fixed sleeve 2, a limiting sleeve 504 is fixedly installed on the front inner wall of the outer shell 1, a trapezoidal push plate 505 is slidably installed inside the limiting sleeve 504, the end of the trapezoidal push plate 505 is fixedly connected to the mounting plate 503, the front end of the trapezoidal push plate 505 extends outside the outer shell 1 and is slidably connected to the outer shell 1, a rotating shaft 506 is fixedly installed on the output shaft of the servo motor 3, the front end of the rotating shaft 506 extends outside the outer shell 1 and is rotatably connected to the outer shell 1, and a hollow connecting block 507 is fixedly sleeved on the rotating shaft 506. Trapezoidal tooth plates 508 are slidably installed on the left and right sides of the hollow connecting block 507 respectively.

[0040] As Figure 3As shown in the figure, a number of fixed plates 509 are fixedly installed on the outer wall of the fixed sleeve 2. On the front surfaces of the number of fixed plates 509, a number of return springs 510 are fixedly installed respectively. The front ends of the number of return springs 510 are fixedly connected to the inner wall of the front surface of the housing 1.

[0041] The fixed sleeve 2 drives the fixed plates 509 to move simultaneously. At this time, since the fixed plates 509 move away from the trapezoidal push plate 505, the return springs 510 will undergo tensile deformation. When the cleaning sleeve 502 moves, it will scrape the dust falling on the heat dissipation plate 4 onto the inner wall of the housing 1. When the trapezoidal tooth plate 508 leaves the trapezoidal push plate 505, at this time, the trapezoidal push plate 505 will reset under the elastic force of the return spring 510. Therefore, the cleaning sleeve 502 will form a reciprocating movement.

[0042] As Figure 2 shown in the figure, a heat dissipation mechanism 6 is arranged in the housing 1. The heat dissipation mechanism 6 includes a U-shaped circular box 601 fixedly installed on the inner wall of the housing 1. The rotating shaft 506 penetrates through the U-shaped circular box 601 and is rotatably connected to the U-shaped circular box 601. A number of heat dissipation fan blades 602 are fixedly installed on the outer wall of the rotating shaft 506. A number of air inlet holes 603 are opened on the front surface of the housing 1.

[0043] During the rotation of the rotating shaft 506, it will drive a number of heat dissipation fan blades 602 to rotate. The rotation of the heat dissipation fan blades 602 will generate a suction force, which will suck the outside air into the housing 1 through the air inlet holes 603.

[0044] As Figure 6 shown in the figure, an arc-shaped hollow block 604 is fixedly installed on the back surface of the housing 1. An arc-shaped plate 605 is fixedly installed on the inner wall of the top of the arc-shaped hollow block 604. A telescopic spring 606 is fixedly installed on the back surface of the arc-shaped plate 605. The end of the telescopic spring 606 is fixedly installed with an arc-shaped sealing plate 607. The arc-shaped sealing plate 607 is slidably connected to the arc-shaped hollow block 604.

[0045] As the gas entering the housing 1 accumulates more and more, the air pressure inside the housing 1 continuously increases. The gas will enter the arc-shaped hollow block 604 through the arc-shaped gap between the arc-shaped plate 605 and the arc-shaped hollow block 604.

[0046] As Figure 6 shown in the figure, two strip-shaped limit sliding grooves 608 are opened on the inner wall of the arc-shaped hollow block 604. L-shaped limit plates 609 are respectively slidably installed in the two strip-shaped limit sliding grooves 608. The ends of the two L-shaped limit plates 609 are fixedly connected to the arc-shaped sealing plate 607.

[0047] The air will push the arc sealing plate 607 to move away from the outer shell 1. At this time, the telescopic spring 606 will be stretched and deformed, and the arc sealing plate 607 will leave the arc hollow block 604. In the process of the arc hollow block 604 leaving, it will also drive the L-shaped limit plate 609 to move. The L-shaped limit plate 609 will slide along the track of the strip limit slide groove 608 to play a limiting role. When the arc sealing plate 607 leaves the arc hollow block 604, the air will be blown out from the gap between the arc sealing plate 607 and the arc hollow block 604. In the process of air being discharged from the outer shell 1, the fine dust that falls on the inner wall of the outer shell 1 will be taken away, ensuring that the dust in the outer shell 1 can be effectively cleaned to prevent dust from affecting the normal operation of the servo motor 3.

[0048] like Figure 1 and Figure 8 As shown, two transmission mechanisms 7 are arranged in the hollow connecting block 507, and the transmission mechanism 7 includes a transmission spring 701 fixedly mounted on the inner wall of the hollow connecting block 507, the end of the trapezoidal tooth plate 508 extends into the hollow connecting block 507 and is fixedly connected to the transmission spring 701, and an L-shaped arc plate 702 is fixedly mounted on the outer wall of the outer shell 1.

[0049] Dust particles in the air will adhere to the surface of the air inlet 603 and cause blockage. At this time, the trapezoidal tooth plate 508 will contact the L-shaped arc plate 702 during the rotation process, and the trapezoidal tooth plate 508 will slide into the hollow connecting block 507 under the action of the inclined surface of the trapezoidal tooth plate 508.

[0050] like Figure 7 and Figure 8 As shown, a plurality of rotating rods 703 are rotatably mounted on the front inner wall of the hollow connecting block 507, a plurality of teeth 704 are fixedly mounted on the outer walls of the plurality of rotating rods 703, the plurality of teeth 704 are all meshed with the trapezoidal tooth plate 508, the ends of the plurality of rotating rods 703 are all extended to the outside of the hollow connecting block 507, and brushes 705 are fixedly mounted on the ends of the plurality of rotating rods 703, and the plurality of brushes 705 are all in contact with the outer shell 1.

[0051] The trapezoidal tooth plate 508 will contact a number of teeth 704, and the number of teeth 704 will drive a number of rotating rods 703 to rotate, and the rotating rods 703 will drive a number of brushes 705 to rotate. Since the trapezoidal tooth plate 508 rotates around the rotating shaft 506, the brushes 705 will clean a number of air inlet holes 603 on the front side of the shell 1 when they rotate, thereby improving the cleanliness of the surface of the air inlet holes 603 and effectively preventing dust from clogging the air inlet holes 603.

[0052] like Figure 1-9 A method for a servo motor protection structure is shown, and the method steps are as follows:

[0053] S1: When in use, start the servo motor 3, the servo motor 3 drives the rotating shaft 506 to rotate, the rotating shaft 506 drives the hollow connecting block 507 to rotate, the hollow connecting block 507 drives the trapezoidal tooth plate 508 to rotate, the trapezoidal tooth plate 508 will contact the trapezoidal push plate 505 during the rotation process, the trapezoidal push plate 505 will move towards the direction close to the servo motor 3 under the action of its inclined surface, the trapezoidal push plate 505 will push the mounting plate 503 to move, the mounting plate 503 drives the fixed sleeve 2 to slide, and the fixed sleeve 2 drives the fixed plate 509 to move at the same time At this time, since the fixing plate 509 moves away from the trapezoidal push plate 505, the return spring 510 will be stretched and deformed, and the cleaning sleeve 502 will scrape the dust falling on the heat sink 4 to the inner wall of the housing 1 when moving. When the trapezoidal tooth plate 508 leaves the trapezoidal push plate 505, the trapezoidal push plate 505 will be reset under the elastic force of the return spring 510, so the cleaning sleeve 502 will form a reciprocating movement. In the process of the reciprocating movement of the cleaning sleeve 502, the dust falling on the surface of the heat sink 4 will be cleaned off;

[0054] S2: During the rotation of the rotating shaft 506, a plurality of heat dissipation blades 602 will be driven to rotate. The rotation of the heat dissipation blades 602 will generate a suction force, and the outside air will be sucked into the housing 1 through the air inlet 603. At the same time, the dust particles in the air will adhere to the surface of the air inlet 603 to cause blockage. At this time, the trapezoidal tooth plate 508 will contact the L-shaped arc plate 702 during the rotation. Under the action of the inclined surface of the trapezoidal tooth plate 508, the trapezoidal tooth plate 508 will slide into the hollow connecting block 507, and the trapezoidal tooth plate 508 will contact a plurality of teeth 704. The plurality of teeth 704 will drive a plurality of rotating rods 703 to rotate, and the rotating rods 703 will drive a plurality of brushes 705 to rotate. Since the trapezoidal tooth plate 508 rotates around the rotating shaft 506, the plurality of air inlet holes 603 on the front side of the housing 1 will be cleaned when the brushes 705 rotate.

[0055] S3: As more and more gas enters the shell 1, the air pressure in the shell 1 continues to increase, and the gas will enter the arc-shaped hollow block 604 through the arc-shaped gap between the arc-shaped plate 605 and the arc-shaped hollow block 604. The air will push the arc-shaped sealing plate 607 to move away from the shell 1. At this time, the telescopic spring 606 is stretched and deformed, and the arc-shaped sealing plate 607 will leave the arc-shaped hollow block 604. In the process of the arc-shaped hollow block 604 leaving, it will also drive the L-shaped limit plate 609 to move. The L-shaped limit plate 609 will slide along the track of the strip-shaped limit slide groove 608 to play a limiting role. When the arc-shaped sealing plate 607 leaves the arc-shaped hollow block 604, the air will be blown out from the gap between the arc-shaped sealing plate 607 and the arc-shaped hollow block 604. In the process of the air being discharged from the shell 1, the fine dust that falls on the inner wall of the shell 1 will be taken away together;

[0056] S4: After stopping the operation of the servo motor 3, heat dissipation air will not be injected into the outer shell 1. As the air pressure in the outer shell 1 decreases, the arc-shaped sealing plate 607 will return to the arc-shaped hollow block 604 under the elastic force of the telescopic spring 606 and the limiting action of the L-shaped limiting plate 609. At this time, the arc-shaped hollow block 604 restores the sealing state to prevent external dust from entering the outer shell 1 through the gap between the arc-shaped hollow block 604 and the arc-shaped sealing plate 607 when the servo motor 3 is not in use.

7. A method for using a servo motor protection structure, using the servo motor protection structure according to claim 6, characterized in that: The steps are as follows: S1: When in use, the servo motor (3) is started, the servo motor (3) drives the rotating shaft (506) to rotate, the rotating shaft (506) drives the hollow connecting block (507) to rotate, the hollow connecting block (507) drives the trapezoidal tooth plate (508) to rotate, the trapezoidal tooth plate (508) contacts the trapezoidal push plate (505) during the rotation process, the trapezoidal push plate (505) moves in a direction close to the servo motor (3) under the action of its inclined surface, the trapezoidal push plate (505) pushes the mounting plate (503) to move, the mounting plate (503) drives the fixing sleeve (2) to slide, and the fixing sleeve (2) drives the fixing plate (509) At the same time, since the fixed plate (509) moves in a direction away from the trapezoidal push plate (505), the return spring (510) will be stretched and deformed, and the cleaning sleeve (502) will scrape the dust that has fallen on the heat sink (4) onto the inner wall of the housing (1) when it moves. When the trapezoidal tooth plate (508) leaves the trapezoidal push plate (505), the trapezoidal push plate (505) will be reset under the elastic force of the return spring (510), so the cleaning sleeve (502) will form a reciprocating movement, and the dust that has fallen on the surface of the heat sink (4) will be cleaned off during the reciprocating movement of the cleaning sleeve (502); S2: During the rotation of the rotating shaft (506), a plurality of heat dissipation blades (602) are driven to rotate. The rotation of the heat dissipation blades (602) generates a suction force, which draws the outside air into the housing (1) through the air inlet (603). At the same time, dust particles in the air adhere to the surface of the air inlet (603) and cause blockage. At this time, the trapezoidal tooth plate (508) contacts the L-shaped arc plate (702) during the rotation process. Under the action of the inclined surface of the trapezoidal tooth plate (508), The trapezoidal tooth plate (508) slides into the hollow connecting block (507), the trapezoidal tooth plate (508) contacts a plurality of teeth (704), the plurality of teeth (704) drive a plurality of rotating rods (703) to rotate, the rotating rods (703) drive a plurality of brushes (705) to rotate, and since the trapezoidal tooth plate (508) rotates around the rotating shaft (506), the brushes (705) clean a plurality of air inlet holes (603) on the front side of the housing (1) when rotating; S3: As more and more gas enters the housing (1), the gas pressure in the housing (1) increases continuously, and the gas enters the arc-shaped hollow block (604) through the arc-shaped gap between the arc-shaped plate (605) and the arc-shaped hollow block (604). The air pushes the arc-shaped sealing plate (607) to move away from the housing (1). At this time, the telescopic spring (606) is stretched and deformed, and the arc-shaped sealing plate (607) leaves the arc-shaped hollow block (604). When the arc-shaped sealing plate (607) leaves the arc-shaped hollow block (604), the L-shaped limiting plate (609) will be driven to move at the same time. The L-shaped limiting plate (609) will slide along the track of the strip-shaped limiting slide groove (608) to play a limiting role. When the arc-shaped sealing plate (607) leaves the arc-shaped hollow block (604), air will be blown out from the gap between the arc-shaped sealing plate (607) and the arc-shaped hollow block (604). In the process of air being discharged from the outer shell (1), fine dust that falls on the inner wall of the outer shell (1) will be taken away together; S4: After the servo motor (3) stops running, heat dissipating air will not be injected into the housing (1). As the air pressure in the housing (1) decreases, the arc-shaped sealing plate (607) will return to the arc-shaped hollow block (604) under the elastic force of the telescopic spring (606) and the limiting action of the L-shaped limiting plate (609). At this time, the arc-shaped hollow block (604) returns to the sealed state, preventing external dust from entering the housing (1) through the gap between the arc-shaped hollow block (604) and the arc-shaped sealing plate (607) when the servo motor (3) is not in use.
