Description

Technical Field

[0001] This utility model relates to the field of sealing ring installation technology, and more specifically, to a fully automatic sealing ring installation device. Background Technology

[0002] Sealing rings are elastic ring-shaped components used in many products requiring sealing. Currently, due to the wide variety of sizes and types of sealing rings, most sealing ring assembly on the market is done manually. This involves fitting the sealing ring onto a fixture that enlarges its diameter, manually peeling it off the fixture, and then assembling the sealing ring onto the product. Existing sealing ring assembly methods rely on manual visual alignment, resulting in poor assembly accuracy, increasing the defect rate of assembled products, and are also labor-intensive and inefficient.

[0003] For example, CN210850045U discloses a sealing ring opening mechanism, comprising: a base, parallel pneumatic grippers with left and right sliding claws, a left linear slide rail, a right linear slide rail, a first and second slider slidably connected to the left linear slide rail, a third and fourth slider slidably connected to the right linear slide rail, a first tension spring connecting the first and second sliders, a second tension spring connecting the third and fourth sliders, a left and right track plates arranged separately, four cam followers pivotally mounted on the four sliders, and four opening columns fixed on the four sliders. However, the above mechanism uses a lifting cylinder to drive the base and its components upward as a whole. This requires a high-power cylinder, which is expensive and bulky, making it difficult to arrange rationally. Furthermore, this mechanism has significant limitations in sealing ring installation. For example, when installing ultra-large or ultra-small diameter sealing rings, it is necessary to replace the material plate or adjust the perforations of the opening columns, which is time-consuming, labor-intensive, and has poor applicability. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a fully automatic sealing ring installation device.

[0005] The objective of this utility model is achieved through the following technical solution: An automatic sealing ring installation device includes a frame and a sealing ring installation assembly mounted thereon. The sealing ring installation assembly includes at least a support plate mounted on the frame. A fixed plate is fixedly mounted on the support plate. A set of sliding grooves are evenly spaced on the fixed plate, and the central axis of the sliding grooves is coaxial with the axis of symmetry of the fixed plate. Clamping blocks for holding the sealing ring and lifting blocks for lifting the sealing ring are intersected within the sliding grooves. The clamping blocks and lifting blocks can move towards or away from the center of the fixed plate under the drive of a driving component. The lifting blocks can move upward under the drive of a lifting component to disengage the sealing ring from the clamping blocks.

[0006] Preferably, the driving component includes at least a turntable disposed between the support plate and the fixed plate, the turntable being pivotally disposed on the support plate; the turntable is provided with a set of inclined guide grooves, the central axis of the guide grooves having an acute angle with the axis of symmetry of the turntable; the guide grooves are provided with guide posts, the other end of the guide posts being pivotally connected to the clamping block and the lifting block.

[0007] Preferably, a drive motor is fixedly mounted on the support plate, a drive gear is fixedly mounted on the motor shaft of the drive motor, and a toothed surface is fixedly mounted on the outer circumference of the turntable, the toothed surface meshing with the drive gear.

[0008] Preferably, the groove includes a first groove and a second groove formed on the lower half of the fixed plate, and a small groove formed on the upper half of the fixed plate. The height of the first groove is greater than the height of the second groove, and the width of the small groove is less than the width of the first groove and the second groove, and they are interconnected.

[0009] Preferably, the clamping block consists of a large clamping end and a small diameter end. The width of the large clamping end is equal to the width of the second groove, and the height of the large clamping end is equal to the height of the second groove. The width of the small diameter end is equal to the width of the small groove, and an upwardly protruding baffle is provided on the inner side of the small diameter end.

[0010] Preferably, the lifting block consists of a large lifting end and a small lifting end. The width of the large lifting end is equal to the width of the first groove, the height of the large lifting end is less than the height of the first groove, and the maximum distance that the large lifting end can move within the first groove is greater than or equal to the height of the baffle.

[0011] Preferably, the lifting assembly includes at least a slide rod slidably disposed on the support plate, a cover plate fixedly disposed on the slide rod, a trapezoidal groove corresponding to the slide groove being formed on the lower surface of the cover plate, an equal-height bolt being disposed in the trapezoidal groove, and the other end of the equal-height bolt being screwed into a threaded hole on the lifting block.

[0012] Preferably, a lifting cylinder is fixedly mounted on the support plate, a lifting plate is fixedly mounted on the cylinder shaft of the lifting cylinder, and the slide rod is fixedly mounted on the lifting plate.

[0013] Preferably, a support frame is also fixed on the frame, and a support cylinder is fixed on the support frame. A set of vertically arranged positioning grooves are opened on the outer circumferential surface of the support cylinder.

[0014] Preferably, the bearing cylinder has an internal push plate, and the push plate has external protrusions around its perimeter, with at least a portion of the external protrusions located outside the positioning groove; a telescopic cylinder is fixed on the frame, and the cylinder shaft of the telescopic cylinder is connected to the external protrusions.

[0015] The beneficial effects of this utility model are mainly reflected in: 1. The design is ingenious. The lifting block and the clamping block slide synchronously along the central axis of the slide groove, which can ensure the accuracy of the movement position and the precision of the clamping. At the same time, since the lifting block and the clamping block move synchronously, compared with the rotational movement of the top rod in the prior art, interference and service life can be avoided. In addition, the structure layout is more compact and reasonable, which facilitates the installation layout. Furthermore, the device can be used for the installation of sealing rings of various specifications, making it highly adaptable.

[0016] 2. By transmitting power through the meshing of the drive gear and tooth surface, a constant transmission ratio can be ensured. There is no elastic slippage or sliding phenomenon during transmission, ensuring the synchronization of transmission. In addition, the friction loss during transmission is small, making it suitable for high-precision and high-efficiency mechanical transmission. Moreover, the structure is compact, reducing the space occupied.

[0017] 3. When the turntable rotates, the drive guide column slides in the guide groove, so that the clamping block and the lifting block slide along the central axis of the slide groove on the fixed plate, thereby realizing position adjustment. This adjustment method is stable and reliable, and is easy to disassemble, maintain and repair, which greatly improves work efficiency.

[0018] 4. Compared with existing technologies, this design uses a lifting cylinder that only drives the lifting plate upward, rather than driving the entire structure. This allows for the use of a smaller lifting cylinder, which is smaller in size and easier to arrange. In addition, it is much cheaper than a high-power cylinder, which can significantly reduce enterprise costs.

[0019] 5. The telescopic cylinder extends or retracts, which can drive the outer protrusion to move up or down, thereby adjusting the position of the sealing ring. This adjustment method is simple, convenient, stable and reliable. Attached Figure Description

Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] like Figures 1 to 5 As shown, this utility model discloses a fully automatic sealing ring installation device, including a frame 1 and a sealing ring installation component 2 disposed thereon. The above is a preferred embodiment of this utility model. The frame 1 may also be provided with a snap ring installation component, a snap ring bearing component, and a workpiece bearing component, etc., all of which fall within the protection scope of this utility model.

[0026] In this application, the sealing ring mounting assembly 2 includes at least a support plate 21 mounted on the frame 1. A fixing plate 22 is fixed on the support plate 21. A set of sliding grooves 23 are evenly spaced on the fixing plate 22, and the central axis of the sliding grooves 23 is coaxial with the axis of symmetry of the fixing plate 22. Clamping blocks 24 for clamping the sealing ring 100 and lifting blocks 25 for lifting the sealing ring 100 are intersected within the sliding grooves 23. The clamping blocks 24 and lifting blocks 25 can move towards or away from the center of the fixing plate 22 under the drive of the driving member 26. The lifting blocks 25 can move upward under the drive of the lifting assembly 27 to disengage the sealing ring 100 from the clamping blocks 24. The above design is ingenious. The lifting block 25 and the clamping block 24 slide synchronously along the central axis of the slide groove 23, which can ensure the accuracy of the moving position and the precision of the clamping. At the same time, since the lifting block 25 and the clamping block move synchronously, compared with the rotating motion of the top rod in the prior art, interference and loss of service life can be avoided. In addition, the structure layout is more compact and reasonable, which facilitates the installation layout.

[0027] Specifically, the driving component 26 includes at least a turntable 261 disposed between the support plate 21 and the fixed disk 22, the turntable 261 being pivotally mounted on the support plate 21. A toothed surface is fixed to the outer circumference of the turntable 261, a drive motor is fixed to the support plate 21, and a drive gear 264 is fixed to the motor shaft of the drive motor. The toothed surface meshes with the drive gear 264. Power is transmitted through the meshing of the drive gear 264 and the toothed surface, ensuring a constant transmission ratio and eliminating elastic slippage or sliding during transmission, thus ensuring synchronous transmission. Furthermore, this structure exhibits low frictional loss during transmission, making it suitable for high-precision, high-efficiency mechanical transmissions, and its compact structure reduces space requirements.

[0028] The turntable 261 has a set of inclined guide grooves 262, with an acute angle between the central axis of the guide grooves 262 and the axis of symmetry of the turntable 261. A guide post is embedded in each guide groove 262, and the other end of the guide post is pivotally connected to the clamping block 24 and the lifting block 25. When the turntable 261 rotates, the drive guide post slides within the guide grooves 262, causing the clamping block 24 and the lifting block 25 to slide along the central axis of the slide groove 23 on the fixed plate 22, thereby achieving position adjustment. This adjustment method is stable and reliable, and facilitates disassembly, maintenance, and repair, greatly improving work efficiency.

[0029] In this utility model, the sliding groove 23 includes a first groove 231 and a second groove 239 formed on the lower half of the fixed disk 22, and a small groove 232 formed on the upper half of the fixed disk 22. The first groove 231 and the second groove 239 are intersecting, the height of the first groove 231 is greater than the height of the second groove 239, and the width of the small groove 232 is less than the width of the first groove 231 and the second groove 239, and they are interconnected. The clamping block 24 is composed of a large clamping end 241 and a small diameter end 242. The width of the large clamping end 241 is equal to the width of the second groove 239, and the height of the large clamping end 241 is equal to the height of the second groove 239; the width of the small diameter end 242 is equal to the width of the small groove 232, and an upwardly protruding baffle 243 is provided on the inner side of the small diameter end 242. The lifting block 25 is composed of a large lifting end 251 and a small lifting end 252. The width of the large lifting end 251 is equal to the width of the first groove 231, the height of the large lifting end 251 is less than the height of the first groove 231, and the maximum distance that the large lifting end 251 moves within the first groove 231 is greater than or equal to the height of the baffle 243.

[0030] The lifting assembly 27 includes at least a slide rod 271 slidably mounted on the support plate 21. A cover plate 272 is fixedly mounted on the slide rod 271. A trapezoidal groove corresponding to the sliding groove 23 is formed on the lower surface of the cover plate 272. An equal-height bolt is embedded in the trapezoidal groove, and the other end of the equal-height bolt is screwed into a threaded hole 273 on the lifting block 25. A lifting cylinder 274 is fixedly mounted on the support plate 21. A lifting plate 275 is fixedly mounted on the cylinder shaft of the lifting cylinder 274, and the slide rod 271 is fixedly mounted on the lifting plate 275. Compared with the prior art, this design only drives the lifting plate 275 to move upward, rather than driving the entire assembly. This allows for the use of a smaller lifting cylinder, which is smaller in size and easier to arrange rationally. In addition, compared with a high-power cylinder, it is much cheaper, which can significantly reduce enterprise costs.

[0031] Furthermore, a support frame 3 is fixedly mounted on the frame 1, and a support cylinder 32 is fixedly mounted on the support frame. A set of vertically arranged positioning grooves 33 are formed on the outer circumferential surface of the support cylinder 32. An upper push plate 34 is built into the support cylinder 32, and external protrusions 35 are provided around the upper push plate 34. At least part of the external protrusions 35 are located outside the positioning grooves 33. A telescopic cylinder 36 is fixedly mounted on the frame 1, and the cylinder shaft of the telescopic cylinder 36 is connected to the external protrusions 35. The telescopic cylinder 36 extends or retracts, driving the external protrusions 35 to move upwards or downwards, thereby adjusting the position of the sealing ring. This adjustment method is simple, convenient, stable, and reliable.

[0032] The working process of this utility model is briefly described below: The robotic arm clamps and transfers the sealing ring fitted on the bearing cylinder 32 to the small diameter end 242. The baffle 243 is located inside the sealing ring. At this time, the drive motor starts and drives the turntable 261 to rotate forward through the drive gear 264. The drive guide column slides in the guide groove 262, so that the clamping block 24 and the lifting block 25 slide backward along the central axis of the slide groove 23 on the fixed plate 22, causing the sealing ring to open.

[0033] The robotic arm clamps and transfers the workpiece into the sealing ring. At this time, the lifting cylinder 274 is activated, driving the lifting plate 275 to move upward, so that the lifting block 25 moves upward in the first groove 231, thereby assembling the sealing ring onto the workpiece.

[0034] It should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0035] The detailed descriptions listed above are merely specific descriptions of feasible implementations of this utility model, and are not intended to limit the scope of protection of this utility model. All equivalent implementations or modifications made without departing from the spirit of this utility model should be included within the scope of protection of this utility model.
