A servo electric cylinder with dust-proof mechanism

Abstract

The present invention discloses a servo electric cylinder with a dust-proof mechanism, which relates to the technical field of servo electric cylinders. In the existing dust removal, the surface of the telescopic cylinder of the electric cylinder is dust-cleaned by scraping. However, in the process of scraping, the lubricating oil on the surface is also scraped off, which causes increased wear of the equipment. The spiral scraper cooperates with the connecting swivel. When cleaning the lubricating oil and dust agglomerates on the slide cylinder surface, 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 increases. In combination with the power of the telescopic movement, the dust and oil agglomerates are cleaned, thereby improving the cleaning effect. At the same time, when there is no dust agglomerate on the slide cylinder surface, the notch provides a gap for the passage of lubricating oil, thereby avoiding scraping off a large amount of lubricating oil during cleaning, which causes increased wear.

Description

Technical Field

[0001] The present invention relates to the technical field of servo electric cylinders, and 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 screw axis. 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 from the surface of the telescopic cylinder of the electric cylinder to prevent dust from entering the cylinder during the telescopic movement. However, during 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;

[0006] A transmission mechanism, wherein the transmission mechanism is installed inside the cylinder body, and one end of the transmission mechanism is connected to the output end of the servo motor through a coupling;

[0007] A dustproof mechanism, the dustproof mechanism being fixedly mounted on the outer side of the cylinder body at one end away from the servo motor;

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

[0009] The cleaning mechanism comprises a connecting disc, which is fixedly mounted on one end of the cylinder away from the servo motor, and a fixed grooved cylinder is fixedly mounted on the outer side of the connecting disc, and 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 provided on the side of the spiral scraper away from the connecting swivel, and notches are evenly provided on the blade of the spiral scraper. When the lubricating oil and dust clumps on the surface of the slide cylinder are cleaned, 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 effect. The oil suction ring is fixedly installed on the end of the inner wall of the fixed groove cylinder away from the connecting disk, and contacts with 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 avoid dust aggregation and forming lumps, thereby improving the dust-proof effect. The oil suction ring is made of fiber material.

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

[0011] The outer cover is threadedly connected to the cover by a threaded ring, and the outer cover is fixed with a toothed disc, and the toothed disc is fixed with a toothed disc at a position away from the servo motor. The outer ring cover is inclined to both sides of the sliding block, 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. It has the following beneficial effects:

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

[0014] 2. The servo electric cylinder with a dust-proof mechanism contacts the surface of the slide through the inner wall of the oil suction ring. During the extension and contraction movement of the slide, it rubs against the surface of the slide. When there is more lubricating oil on the surface of the slide, it absorbs it and applies it to the area with less lubricating oil, 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 in it to prevent the dust from gathering and forming lumps, thereby improving the dust-proof effect.

[0015] 3. The servo electric cylinder with a dustproof mechanism cooperates with the dustproof cylinder through a 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 a 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 slides 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 a dust-proof mechanism cooperates 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 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, causing the contact movement between the threaded ring and the screw rod to be obstructed, affecting the operation of the equipment.

[0027] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for purposes of illustration and description and are not intended to be exhaustive or to limit the invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments are chosen and described to better illustrate the principles of the invention and its practical application, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for specific applications.

[0028] The first embodiment, as Figures 1 to 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 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, which is fixedly mounted on an end of the cylinder 1 away from the servo motor 5;

[0033] Among them, the cleaning mechanism 2 includes a connecting disk 21, which is fixedly mounted on the end of the cylinder body 1 away from the servo motor 5, and a fixed grooved cylinder 24 is fixedly mounted on the outer side of the connecting disk 21, and a connecting swivel 25 is rotatably mounted on the inner wall of the fixed grooved cylinder 24. The connecting disk 21 and the fixed grooved cylinder 24 are fixed to the cylinder body 1 through the connecting disk 21 and the fixed grooved cylinder 24, and the fixed grooved cylinder 24 is fixed to the slide hole disk 37 to limit the position of the fixed grooved cylinder 24. At the same time, the inner wall of the fixed grooved cylinder 24 is rotatably mounted 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 slide cylinder 32, a spiral scraper 22 is fixedly mounted on the inner wall of the connecting swivel 25. 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 grooved cylinder 24. During the telescopic movement of the slide cylinder 32, the spiral scraper The blade of the knife 22 scrapes the stains on the surface of the slide cylinder 32 to clean it. At the same time, in the process of scraping, the notches evenly opened on the blade provide gaps for the lubricating oil on the surface of the slide cylinder 32 to avoid scraping off a large amount of lubricating oil when scraping, causing the slide cylinder 32 to enter the cylinder body 1 and cause greater wear. At the same time, when the lubricating oil on the surface of the slide cylinder contacts with dust to form oil lumps, the spiral blade cooperates with the notches. In the process of contact, the contact between the lumps and the spiral scraper 22 causes the connecting ring 25 and the spiral scraper 22 to rotate. During rotation, the blade cooperates with the notches to saw the lumps. After the notches contact the lumps, the resistance increases. With the power of the telescopic movement, the dust and oil lumps are cleaned, and the end of the fixed groove drum 24 away from the connecting disk 21 is fixedly connected to the dustproof mechanism 3. The end of the inner wall of the fixed groove drum 24 away from the connecting disk 21 is fixedly installed with an oil suction ring 23, which is made of fiber material.

[0034] The second embodiment, based on the first embodiment, see Figures 3 and 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 plate 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 plate 37. Sliding rods 33 are slidably installed at the sliding holes of the sliding hole plate 37, and are connected with the transmission mechanism 4 through the slide cylinder 32. 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 made 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 connected to the device to be driven to drive the device to move. One end of the slide rod 33 is fixedly connected to the fixed plate 34, and 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 32 is slidably adapted to the inner wall of the cylinder 1, and the outer side of the slide 32 is in contact with the blade of the spiral scraper 22. The side of the sliding hole disk 37 away from the fixed disk 34 is fixedly connected to the end of the fixed groove cylinder 24 away from the connecting disk 21. When the slide 32 is driven to extend and slide, the fixed disk 34 fixedly connected to the outer side of the slide 32 is used to pull the dustproof cylinder 36 when the slide 32 is extended, so that the dustproof cylinder 36 is stretched and deformed, so that the dustproof cylinder 36 always wraps the slide 32 inside. When it is retracted, 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 on the inside. The dustproof cylinder 36 is fixedly connected between the sliding hole disk 37 and the fixed disk 34. The dustproof cylinder 36 is located on the inner side of the sliding rod 33 and is made of elastic rubber material.

[0036] The third embodiment, based on the first and second embodiments, see Figures 7 and 8 As shown, the transmission mechanism 4 includes a screw rod 41, one end of the screw rod 41 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 screw rod 41 rotates. As the screw rod 41 is driven by the servo motor 5 to rotate in different directions, the sliding block 43 is caused to reciprocate inside the cylinder body 1. During the reciprocating motion, the slide 32 is driven to extend 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 screw rod 41.

[0037] Support plates 46 are fixedly installed on the upper and lower sides of both ends of the sliding block 43, and ball head blocks 48 are fixedly installed on the non-opposite surfaces of the support plates 46. A ball head is provided on the 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 outside of the sliding block 43. The arc convex block 45 is symmetrically installed on the outside of the sliding block 43 along the axis center position 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 inner wall of the cylinder body 1. The inner wall of the cylinder body 1 contacts 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. 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] During use, by starting the servo motor 5, the servo motor 5 is connected to the transmission mechanism 4 through the output end, driving the transmission mechanism 4 to operate, and utilizing the connection between the transmission mechanism 4 and the dustproof mechanism 3 to drive the dustproof mechanism 3 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, and 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 1, the slide 32 is connected to the transmission mechanism 4 at one end, so that the slide 32 slides on the inner wall of the cylinder 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 fixed plate 34 fixedly connected to the outside of the slide 32 is used to make the slide 32 When extended, 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 contracted, 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 fixed disk 34 drives the sliding rod 33 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 on the inside.

[0040] In the cleaning mechanism 2, the connecting disc 21 and the fixed grooved cylinder 24 are fixed to the cylinder body 1, and the fixed grooved cylinder 24 is fixed to the slide hole disc 37 to limit the position of the fixed grooved cylinder 24. At the same time, the inner wall of the fixed grooved 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 groove 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 on the slide 32 when it enters the cylinder 1. At the same time, when the lubricating oil on the slide surface contacts with dust to form oil agglomerates, the spiral blade cooperates with the groove. 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 groove to saw the agglomerates. The resistance increases after the groove position contacts the agglomerates, and the dust and oil agglomerates are cleaned with the power of the telescopic movement.

[0041] The servo motor 5 is connected to the screw rod 41 by the screw rod 41, and 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 1. According to the rotation of the screw rod 41 in different directions by the servo motor 5, the sliding block 43 is reciprocated inside the cylinder 1. During the reciprocating motion, the fixed cylinder 44 drives the slide cylinder 32 to extend and reciprocate. At the same time, during the movement of the fixed cylinder 44, the ball head block 48 and the arc protrusion 45 contact the inner wall of the cylinder 1 to limit the rotation of the sliding block 43, so that the sliding block 43 slides inside the cylinder 1 according to the threaded connection between the threaded ring 49 and the screw rod 41. At the same time, the arc protrusion 45 cooperates with the outer ring cover 47. During the sliding process, the wear debris caused by the friction between the arc protrusion 45 and the inner wall of the cylinder 1 is blocked by the outer ring cover 47.

[0042] Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without making creative efforts should fall within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described and explained in the present invention shall be implemented in accordance with conventional means in the field unless otherwise specified or limited.
