Description

Technical Field

[0001] The invention relates to the technical field of servo electric cylinders, in particular to a servo electric cylinder with a dustproof mechanism. Background Art

[0002] At present, the servo electric cylinder is a device that converts the rotational motion of the servo motor into linear motion through a screw or nut. It integrates servo motor technology, screw transmission technology and precision machinery manufacturing technology. The servo electric cylinder receives external control signals such as pulse signals and analog signals through the control system. These signals specify the target position, speed and acceleration parameters of the electric cylinder. The servo motor rotates according to the requirements of the control signal and transmits the rotational motion to the screw through the coupling. When the screw rotates, it drives the nut that matches it to move linearly along the axial direction of the screw. The nut is then connected to the load through the connecting component, thereby realizing the linear motion of the load.

[0003] In existing servo electric cylinders, scraping is usually used to remove dust and clean the surface of the telescopic cylinder of the electric cylinder to prevent dust from entering the cylinder body during the telescopic movement. However, in the scraping process, the lubricating oil on the surface is also scraped off, resulting in increased wear of the equipment. Summary of the invention

[0004] To achieve the above objectives, the present invention is implemented through the following technical solutions: A servo electric cylinder with a dustproof mechanism, comprising:

[0005] A cylinder body, one end of which is fixedly mounted with a servo motor, and an output end of the servo motor passes through the cylinder body and extends into the interior thereof;

[0008] A cleaning mechanism, which is fixedly mounted on an end of the cylinder body away from the servo motor;

[0009] Wherein, the cleaning mechanism comprises a connecting disk, which is fixedly mounted on one end of the cylinder body away from the servo motor, and a fixed grooved cylinder is fixedly mounted on the outer side of the connecting disk, a connecting swivel is rotatably mounted on the inner wall of the fixed grooved cylinder, and a spiral scraper is fixedly mounted on the inner wall of the connecting swivel, and a blade is arranged on the side of the spiral scraper away from the connecting swivel, and the blade of the spiral scraper is evenly provided with notches, and the spiral scraper cooperates with the connecting swivel, and when cleaning the lubricating oil and dust agglomerates on the surface of the slide cylinder, the notches on the blade of the spiral scraper cooperate with the blade, and the contact between the agglomerates and the spiral scraper causes the connecting ring and the spiral scraper to rotate, and the blade cooperates with the notches during rotation to saw the agglomerates, and the resistance increases after the notches contact the agglomerates, and the dust and oil agglomerates are cleaned with the power of the telescopic movement, thereby improving the cleaning efficiency. The cleaning effect is achieved by the groove, and at the same time, when there is no dust agglomeration on the surface of the slide cylinder, a gap is provided for the passage of lubricating oil to avoid scraping off a large amount of lubricating oil during cleaning, which leads to increased wear. The outer side of the fixed groove cylinder is evenly provided with through grooves, and the end of the fixed groove cylinder away from the connecting disk is fixedly connected to the dust-proof mechanism. An oil suction ring is fixedly installed on the end of the inner wall of the fixed groove cylinder away from the connecting disk, and the inner wall of the oil suction ring contacts the surface of the slide cylinder. During the telescopic movement of the slide cylinder, it rubs against the surface of the slide cylinder. When there is more lubricating oil on the surface of the slide cylinder, it is absorbed and applied to the area with less lubricating oil content, thereby improving the uniformity of the lubricating oil and making the servo electric cylinder run smoother. At the same time, when absorbing the lubricating oil, the dust contaminated therein can be adsorbed to avoid dust aggregation and formation of agglomerations, thereby improving the dust-proof effect. The oil suction ring is made of fiber material.

[0010] Preferably, the dustproof mechanism includes a fixing frame, the fixing frame is fixedly installed on one end of the outer side of the cylinder body away from the servo motor, and a sliding hole disk is fixedly installed on one end of the fixing frame, the outer side of the sliding hole disk is evenly provided with sliding holes, and sliding rods are slidably installed at the sliding holes of the sliding hole disk, and the sliding rods cooperate with the dustproof cylinder. During the working process, the rubber material of the dustproof cylinder is stretched and compressed to wrap the sliding cylinder to prevent it from contacting more dust, thereby improving the dustproof effect. At the same time, the sliding rod surrounds the dustproof cylinder inside to provide protection for the dustproof cylinder. One end is fixedly connected to a fixed plate, the inner wall of the fixed plate is fixedly connected to a sliding cylinder, one end of the sliding cylinder is fixedly connected to a connecting head, the other end of the sliding cylinder is fixedly connected to a transmission mechanism, the outer side of the sliding cylinder is slidably adapted to the inner wall of the cylinder body, and the outer side of the sliding cylinder is in contact with the blade of the spiral scraper, the side of the sliding hole plate away from the fixed plate is fixedly connected to the end of the fixed groove cylinder away from the connecting plate, a dustproof cylinder is fixedly connected between the sliding hole plate and the fixed plate, the dustproof cylinder is located on the inner side of the sliding rod, and the dustproof cylinder is made of elastic rubber material.

[0011] The cam is connected with the drive shaft by the spring, and the cam is connected with the drive shaft by the spring, and the cam is connected with the drive shaft by the spring. The cam is in contact with the inner wall of the cylinder body, reducing the contact area with the cylinder body, reducing friction, reducing friction loss, and improving the service life of the servo electric cylinder. The ball head block contacts the inner wall of the cylinder body through the ball head, and an arc protrusion is fixedly installed on the outer side of the sliding block. The arc protrusion is symmetrically installed on the outer side of the sliding block along the center position of the axis of the screw rod, and the arc protrusion fits the inner wall of the cylinder body. Both ends of the outer side of the sliding block are fixedly installed with outer ring covers, which cooperate with the arc protrusion through the outer ring cover. During the sliding process, when debris is generated by friction between the arc protrusion and the inner wall of the cylinder body, the debris is blocked and restricted by the outer ring covers on both sides to prevent the debris from falling directly into the thread of the screw rod, resulting in obstruction of the contact movement between the threaded ring and the screw rod, affecting the operation of the equipment, and the end of the outer ring cover away from the sliding block is inclined to both sides, and the end of the outer ring cover away from the sliding block does not contact the inner wall of the cylinder body.

[0012] The present invention provides a servo electric cylinder with a dustproof mechanism, which has the following beneficial effects:

[0013] 1. The servo electric cylinder with dust-proof mechanism cooperates with the connecting swivel through the spiral scraper. When cleaning the lubricating oil and dust agglomerates on the surface of the slide tube, the notch at the blade of the spiral scraper cooperates with the blade. Through the contact between the agglomerates and the spiral scraper, the connecting swivel and the spiral scraper are rotated. During the rotation, the blade cooperates with the notch to saw the agglomerates. After the notch position contacts the agglomerates, the resistance is increased. With the power of the telescopic movement, the dust and oil agglomerates are cleaned, and the cleaning effect is improved. At the same time, when there are no dust agglomerates on the surface of the slide tube, the notch provides a gap for the passage of lubricating oil to avoid scraping off a large amount of lubricating oil during cleaning, which leads to increased wear.

[0014] 2. The servo electric cylinder with dustproof mechanism contacts the surface of the slide cylinder through the inner wall of the oil suction ring. During the telescopic movement of the slide cylinder, it rubs against the surface of the slide cylinder. When there is more lubricating oil on the surface of the slide cylinder, it absorbs it and applies it to the area with less lubricating oil content, thereby improving the uniformity of the lubricating oil and making the operation of the servo electric cylinder smoother. At the same time, when absorbing the lubricating oil, it can adsorb the dust contaminated therein to prevent the dust from gathering and forming lumps, thereby improving the dustproof effect.

[0015] 3. The servo electric cylinder with dustproof mechanism cooperates with the dustproof cylinder through the sliding rod. During operation, the rubber material of the dustproof cylinder is stretched and compressed to wrap the sliding cylinder to prevent it from contacting more dust, thereby improving the dustproof effect. At the same time, the sliding rod surrounds the dustproof cylinder inside to provide protection for the dustproof cylinder.

[0016] Fourth, the servo electric cylinder with dustproof mechanism limits the rotation of the sliding block on both sides of the sliding block through the ball head block, ensuring that the sliding block can slide smoothly under the action of the threaded ring and the screw rod. At the same time, the ball head block contacts the inner wall of the cylinder body through the ball head, reducing the contact area with the cylinder body, reducing friction, reducing friction loss, and improving the service life of the servo electric cylinder.

[0017] 5. The servo electric cylinder with dustproof mechanism cooperates with the arc protrusion through the outer ring cover. During the sliding process, when debris is generated by the friction between the arc protrusion and the inner wall of the cylinder body, the outer ring covers on both sides block and limit the debris to prevent the debris from falling directly into the thread of the screw rod, resulting in obstruction of the contact movement between the threaded ring and the screw rod, affecting the operation of the equipment.

Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.

[0028] The first embodiment, as Figure 1 to Figure 2 and Figures 5 and 6 As shown, the present invention provides a technical solution: a servo electric cylinder with a dustproof mechanism, comprising:

[0029] A cylinder body 1, one end of which is fixedly mounted with a servo motor 5, and an output end of the servo motor 5 passes through the cylinder body 1 and extends into the interior thereof;

[0030] The transmission mechanism 4 is installed inside the cylinder body 1, and one end of the transmission mechanism 4 is connected to the output end of the servo motor 5 through a coupling;

[0031] A dustproof mechanism 3, which is used to transmit power to the outside, and is fixedly mounted on the outer side of the cylinder body 1 at one end away from the servo motor 5;

[0032] A cleaning mechanism 2, the cleaning mechanism 2 is fixedly mounted on an end of the cylinder body 1 away from the servo motor 5;

[0033] Among them, the cleaning mechanism 2 includes a connecting disk 21, which is fixedly installed at one end of the cylinder body 1 away from the servo motor 5, and a fixed groove cylinder 24 is fixedly installed on the outer side of the connecting disk 21, and a connecting swivel 25 is rotatably installed on the inner wall of the fixed groove cylinder 24. The connecting disk 21 and the fixed groove cylinder 24 are fixed to the cylinder body 1 through the connecting disk 21 and the fixed groove cylinder 24, and the fixed groove cylinder 24 is fixed to the sliding hole disk 37 to limit the position of the fixed groove cylinder 24. At the same time, the inner wall of the fixed groove cylinder 24 is rotatably installed on the connecting swivel 25, so that the connecting swivel 25 is fixedly connected to the spiral scraper 22. Through the contact between the spiral scraper 22 and the surface of the sliding cylinder 32, the inner wall of the connecting swivel 25 is fixedly installed with a spiral scraper 22. A blade is provided on the side of the spiral scraper 22 away from the connecting swivel 25, and notches are evenly opened on the blade of the spiral scraper 22. Through grooves are evenly opened on the outer side of the fixed groove cylinder 24. During the telescopic movement of the sliding cylinder 32, the spiral scraper The blade of the knife 22 scrapes and cleans the stains on the surface of the slide cylinder 32. At the same time, during the scraping process, the evenly arranged grooves on the blade provide a gap for the lubricating oil on the surface of the slide cylinder 32 to avoid scraping off a large amount of lubricating oil during scraping, causing greater wear when the slide cylinder 32 enters the cylinder body 1. At the same time, when the lubricating oil on the surface of the slide cylinder contacts with dust to form oil agglomerates, the spiral blade cooperates with the grooves. During the contact process, the connecting ring 25 and the spiral scraper 22 are rotated through the contact between the agglomerates and the spiral scraper 22. During the rotation, the blade cooperates with the grooves to saw the agglomerates. After the groove position contacts the agglomerates, the resistance increases. With the power of the telescopic movement, the dust and oil agglomerates are cleaned, and the end of the fixed groove cylinder 24 away from the connecting disk 21 is fixedly connected to the dustproof mechanism 3, and the end of the inner wall of the fixed groove cylinder 24 away from the connecting disk 21 is fixedly installed with an oil suction ring 23, and the oil suction ring 23 is made of fiber material.

[0034] The second embodiment is based on the first embodiment. Figure 3 to Figure 4 As shown, the dust-proof mechanism 3 includes a fixed frame 31, which is fixedly installed at one end of the outer side of the cylinder body 1 away from the servo motor 5, and a sliding hole disk 37 is fixedly installed at one end of the fixed frame 31, and sliding holes are evenly opened on the outer side of the sliding hole disk 37, and sliding rods 33 are slidably installed at the sliding holes of the sliding hole disk 37. Through the connection between the slide cylinder 32 and the transmission mechanism 4, when the servo motor 5 drives the transmission mechanism 4 to move inside the cylinder body 1, the connection between one end of the slide cylinder 32 and the transmission mechanism 4 is used to make the slide cylinder 32 slide on the inner wall of the cylinder body 1. When sliding, the connecting head 35 at the other end of the slide cylinder 32 is used to connect with the equipment to be driven to drive the equipment to move, one end of the slide rod 33 is fixedly connected to the fixed plate 34, the inner wall of the fixed plate 34 is fixedly connected to the slide cylinder 32, one end of the slide cylinder 32 is fixedly connected to the connecting head 35, and the other end of the slide cylinder 32 is fixedly connected to the transmission mechanism 4.

[0035] The outer side of the slide tube 32 is slidably adapted to the inner wall of the cylinder body 1, and the outer side of the slide tube 32 is in contact with the blade of the spiral scraper 22. The side of the slide hole plate 37 away from the fixed plate 34 is fixedly connected to the end of the fixed groove cylinder 24 away from the connecting plate 21. When the slide tube 32 is driven to extend and slide, the fixed plate 34 fixedly connected to the outer side of the slide tube 32 is used to pull the dustproof cylinder 36 when the slide tube 32 is extended, so that the dustproof cylinder 36 is stretched and deformed, so that the dustproof cylinder 36 always wraps the slide tube 32 inside, and when it is retracted, The fixed plate 34 approaches the sliding hole plate 37 to compress the dustproof cylinder 36. In the process of the dustproof cylinder 36 being stretched and compressed, the sliding rod 33 is driven by the fixed plate 34 to slide in the sliding hole of the sliding hole plate 37. While the sliding rod 33 limits the telescopic movement direction of the sliding cylinder 32, the sliding rod 33 surrounds the dustproof cylinder 36 on the inside. The dustproof cylinder 36 is fixedly connected between the sliding hole plate 37 and the fixed plate 34. The dustproof cylinder 36 is located on the inner side of the sliding rod 33, and the dustproof cylinder 36 is made of elastic rubber material.

[0036] The third embodiment is based on the first and second embodiments. Figures 7 and 8 As shown, the transmission mechanism 4 includes a screw rod 41, one end of which is rotatably connected to a bearing 42, the screw rod 41 is rotatably connected to the inner wall of the cylinder body 1 through the bearing 42, and the end of the screw rod 41 close to the bearing 42 is connected to the output end of the servo motor 5 through a coupling, the outer side of the screw rod 41 is threadedly connected to a threaded ring 49, the outer side of the threaded ring 49 is fixedly connected to a sliding block 43, and the servo motor 5 drives the screw rod 41 to rotate through the screw rod 41 and the threaded ring 49. The threaded connection makes it possible for the sliding block 43 to slide inside the cylinder body 1 through the threaded ring 49 when the lead screw 41 rotates. The sliding block 43 is driven by the servo motor 5 to rotate in different directions, so that the sliding block 43 reciprocates inside the cylinder body 1. During the reciprocating motion, the slide 32 is driven to retract and reciprocate through the fixed cylinder 44. The end of the sliding block 43 away from the servo motor 5 is fixedly connected to the fixed cylinder 44. The sliding block 43 is fixedly connected to one end of the slide 32 through the fixed cylinder 44, and the slide 32 is located on the outside of the lead screw 41.

[0037] Support plates 46 are fixedly installed on both upper and lower sides of both ends of the sliding block 43, and ball head blocks 48 are fixedly installed on non-opposite surfaces of the support plates 46. A ball head is provided at one end of the ball head block 48 away from the support plate 46, and the ball head block 48 contacts the inner wall of the cylinder body 1 through the ball head. An arc convex block 45 is fixedly installed on the outer side of the sliding block 43. The arc convex block 45 is symmetrically installed on the outer side of the sliding block 43 along the center position of the axis of the screw rod 41, and the arc convex block 45 is in contact with the inner wall of the cylinder body 1. During the movement of the fixed cylinder 44, the ball head block 48 and the arc convex block 45 are in contact with the cylinder body 1. The inner wall of the cylinder body 1 is contacted to limit the rotation of the sliding block 43, so that the sliding block 43 slides inside the cylinder body 1 according to the threaded connection between the threaded ring 49 and the screw rod 41, and at the same time cooperates with the outer ring cover 47 through the arc protrusion 45. During the sliding process, the wear debris caused by the friction between the arc protrusion 45 and the inner wall of the cylinder body 1 is blocked by the outer ring cover 47. The outer ring covers 47 are fixedly installed at both ends of the outer side of the sliding block 43, and the end of the outer ring cover 47 away from the sliding block 43 is inclined to both sides, and the end of the outer ring cover 47 away from the sliding block 43 does not contact the inner wall of the cylinder body 1.

[0038] When in use, by starting the servo motor 5, the servo motor 5 is connected to the transmission mechanism 4 through the output end, so as to drive the transmission mechanism 4 to run, and by utilizing the connection between the transmission mechanism 4 and the dustproof mechanism 3, the dustproof mechanism 3 is driven to slide relative to the cylinder body 1. Through the precise control of the servo motor 5, the dustproof mechanism 3 can be more controlled to complete the extension and retraction of different distances. At the same time, during the extension and retraction process, the dustproof mechanism 3 cooperates with the cleaning mechanism 2, so that when the sliding telescopic part enters the interior of the cylinder body 1, the surface is cleaned to prevent stains from entering the interior.

[0039] In the dustproof mechanism 3, through the connection between the slide 32 and the transmission mechanism 4, when the servo motor 5 drives the transmission mechanism 4 to move inside the cylinder body 1, the slide 32 is connected to the transmission mechanism 4 at one end to make the slide 32 slide on the inner wall of the cylinder body 1. When sliding, the connector 35 at the other end of the slide 32 is connected to the device to be driven to drive the device to move. At the same time, when the slide 32 is driven to telescope and slide, the slide 32 is fixed to the fixed plate 34 on the outside of the slide 32. When extending, the dustproof cylinder 36 is pulled to stretch and deform the dustproof cylinder 36 so that the dustproof cylinder 36 always wraps the slide cylinder 32 inside. When contracting, the fixed disk 34 approaches the sliding hole disk 37 to compress the dustproof cylinder 36. In the process of the dustproof cylinder 36 being stretched and compressed, the sliding rod 33 is driven by the fixed disk 34 to slide in the sliding hole of the sliding hole disk 37. While the sliding rod 33 limits the telescopic movement direction of the slide cylinder 32, the sliding rod 33 surrounds the dustproof cylinder 36 inside.

[0040] In the cleaning mechanism 2, the connecting disk 21 and the fixed groove cylinder 24 are fixed to the cylinder body 1, and the fixed groove cylinder 24 is fixed to the slide hole disk 37 to limit the position of the fixed groove cylinder 24. At the same time, the inner wall of the fixed groove cylinder 24 is installed on the connecting swivel 25 by rotation, so that the connecting swivel 25 is fixedly connected to the spiral scraper 22. Through the contact between the spiral scraper 22 and the surface of the slide cylinder 32, during the telescopic movement of the slide cylinder 32, the stains on the surface of the slide cylinder 32 are scraped and cleaned by the blade of the spiral scraper 22. At the same time, during the scraping process, the uniformly opened holes at the blade are used to clean the dirt on the surface of the slide cylinder 32. The notch provides a gap for the lubricating oil on the surface of the slide 32 to avoid scraping off a large amount of lubricating oil during scraping, which would cause greater wear of the slide 32 when it enters the cylinder body 1. At the same time, when the lubricating oil on the surface of the slide contacts with dust to form oil agglomerates, the spiral blade cooperates with the notch. During the contact process, the connecting ring 25 and the spiral scraper 22 are rotated through the contact between the agglomerates and the spiral scraper 22. During the rotation, the blade cooperates with the notch to saw the agglomerates. The resistance increases after the notch position contacts the agglomerates, and the dust and oil agglomerates are cleaned with the power of the telescopic movement.

[0041] In the transmission mechanism 4, the screw rod 41 is fixedly connected to the output end of the servo motor 5, so that the servo motor 5 drives the screw rod 41 to rotate. The screw rod 41 is threadedly connected to the threaded ring 49. When the screw rod 41 rotates, the threaded ring 49 drives the sliding block 43 to slide inside the cylinder body 1. According to the rotation of the screw rod 41 in different directions driven by the servo motor 5, the sliding block 43 reciprocates inside the cylinder body 1. During the reciprocating motion, the sliding cylinder 32 is driven to telescope and reciprocate through the fixed cylinder 44. At the same time, during the movement of the fixed cylinder 44, the ball head block 48 and the arc convex block 45 contact the inner wall of the cylinder body 1 to limit the rotation of the sliding block 43, so that the sliding block 43 slides inside the cylinder body 1 according to the threaded connection between the threaded ring 49 and the screw rod 41. At the same time, the arc convex block 45 cooperates with the outer ring cover 47. During the sliding process, the wear debris caused by the friction between the arc convex block 45 and the inner wall of the cylinder body 1 is blocked by the outer ring cover 47.
