Description

Technical Field

[0001] This utility model relates to the field of flange processing technology, specifically to a flange inner ring installation device. Background Technology

[0002] like Figure 4 The image shows a cross-sectional view of flange 29. The flange has an annular sealing groove 30, and a sealing ring 31 is fixed inside the sealing groove 30. Currently, the sealing ring 31 is mostly installed manually by inserting it into the sealing groove 30. This method is problematic because the sealing ring is prone to falling off, and manual installation is time-consuming, labor-intensive, and inefficient. Utility Model Content

[0003] In view of the shortcomings of the prior art, this utility model provides a flange inner ring installation device to solve the problems mentioned in the background art.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0005] A flange inner ring installation device includes a housing, a rotating column rotatably connected to the housing, a drive mechanism for rotating the rotating column inside the housing, a turntable connected to the upper end of the rotating column, a centering mechanism on the turntable to center the flange, a frame connected to the housing, a hydraulic cylinder mounted on the frame, a pressure block connected to the telescopic end of the hydraulic cylinder, the pressure block being located directly above the turntable, a glue storage tank on one side of the housing, a pump body mounted on the glue storage tank, the inlet end of the pump body being connected to the glue storage tank via a pipe, a first cylinder mounted on the top of the glue storage tank, a lifting plate connected to the telescopic end of the first cylinder, a second cylinder mounted on the lifting plate, a strip-shaped hole on one side of the frame, the telescopic end of the second cylinder passing through the strip-shaped hole and connected to an L-shaped mounting plate, a spray pipe mounted on the mounting plate, a nozzle connected to the lower end of the spray pipe, and the outlet end of the pump body being connected to the spray pipe via a hose, the extension of the first cylinder driving the nozzle to reach above the turntable.

[0006] Preferably, the centering mechanism includes a lead screw rotatably connected to the turntable, a first motor installed at one end of the turntable and connected to the lead screw in a transmission manner, the lead screw having reverse threads on both sides, and a sliding hole on the turntable along the diameter direction. The centering mechanism also includes sliding plates threaded to both sides of the lead screw, the two sliding plates being equidistant from the center of the lead screw, the upper ends of the two sliding plates extending upward from the sliding hole, and the sliding plates being slidably disposed within the sliding hole.

[0007] The above technical solution involves placing the flange on a turntable, then starting the first motor to drive the lead screw to rotate. During the rotation of the lead screw, the two sliding plates move relative to each other. Since the distance from the center of the lead screw to the two sliding plates is the same, the two sliding plates will clamp the flange in the center, thus centering the flange.

[0008] Preferably, the drive mechanism includes a second motor installed in the chassis, a drive shaft connected to the second motor via a coupling, a main gear connected to the drive shaft, and a secondary gear connected to the rotating column, wherein the main gear and the secondary gear mesh.

[0009] The above technical solution involves starting the second motor, which drives the transmission shaft to rotate. Through the cooperation of the main gear and the auxiliary gear, the rotating column rotates, thereby driving the turntable to rotate.

[0010] Preferably, the glue storage tank is equipped with a level gauge.

[0011] The above technical solution allows the volume of adhesive in the storage tank to be observed using a level gauge.

[0012] Preferably, the glue storage tank has an inlet pipe at the top and an outlet pipe at the bottom on one side.

[0013] The above technical solution allows glue to be added to the glue storage tank through the feed pipe and discharged through the discharge pipe, so as to clean the glue storage tank.

[0014] Preferably, the turntable is provided with multiple positioning mechanisms on its periphery, which fix the flange to the turntable. The positioning mechanism includes an extension plate connected to two sliding plates, a third cylinder mounted on the two extension plates, and a pressure plate connected to the telescopic ends of the two third cylinders, with the two extension plates extending relative to each other.

[0015] In the above technical solution, after the slide plate centers the flange, the pressure plate will reach above the flange. At this time, the third cylinder is extended to drive the pressure plate down, which can press the edge of the flange tightly onto the turntable, so that the flange can be further stabilized.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] The flange is placed on the turntable, centered by the centering mechanism, and clamped to ensure stability. Then, the first cylinder extends, bringing the nozzle above the sealing groove on the flange's top surface. Adhesive is injected into the sealing groove through the nozzle. Simultaneously, the drive mechanism rotates the rotating column, which in turn rotates the turntable, allowing adhesive to be injected throughout the sealing groove. After injection, the sealing ring is placed in the sealing groove. The nozzle is then removed from the flange, and the hydraulic cylinder extends, lowering the pressure block. The pressure block firmly presses the sealing ring into the sealing groove, securing it stably. After the adhesive dries, the sealing ring and flange are assembled. This method of sealing ring installation is not only convenient but also ensures a stable fixation to the flange, effectively preventing the sealing ring from falling off.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1

[0025] Please see Figure 1-3 A flange inner ring installation device includes a housing 1, a rotating column 2 rotatably connected to the housing 1, and a drive mechanism for driving the rotating column 2 to rotate inside the housing 1. A turntable 3 is connected to the upper end of the rotating column 2. The drive mechanism drives the rotating column 2 to rotate, thereby driving the turntable 3 to rotate. Specifically, the drive mechanism includes a second motor 18 installed inside the housing, a transmission shaft connected to the second motor via a coupling, a main gear 19 connected to the transmission shaft, and a secondary gear 20 connected to the rotating column. The main gear 19 and the secondary gear 20 mesh. Starting the second motor 18 drives the transmission shaft to rotate, and through the engagement of the main gear 19 and the secondary gear 20, drives the rotating column 2 to rotate, thereby driving the turntable 3 to rotate.

[0026] The turntable 3 is equipped with a centering mechanism to center the flange. Specifically, the centering mechanism includes a lead screw 14 rotatably connected within the turntable, a first motor 15 mounted at one end of the turntable and driven by the lead screw, and the lead screw 14 having reverse threads on both sides. The turntable 3 has sliding holes 16 along its diameter. The centering mechanism also includes sliding plates 17 threaded to both sides of the lead screw. The distances from the two sliding plates 17 to the center of the lead screw 14 are equal, and the upper ends of both sliding plates 17 extend upward from the sliding holes 16, with the sliding plates 17 slidably disposed within the sliding holes 16. When the flange is placed on the turntable 3, the first motor 15 is started, driving the lead screw 14 to rotate. During the rotation of the lead screw 14, the two sliding plates 17 move relative to each other within the sliding holes 16. Since the distances from the centers of the two sliding plates 17 to the centers of the lead screw 14 are equal, the two sliding plates 17 will clamp the flange in a centered position, thus stabilizing the flange.

[0027] The chassis 2 is connected to a frame 4, and a hydraulic cylinder 5 is installed on the frame 4. The extension end of the hydraulic cylinder 5 is connected to a pressure block 6. The pressure block 6 is located directly above the turntable 3. By controlling the extension of the hydraulic cylinder 5, the pressure block 6 is driven to descend, thereby pressing the sealing ring 29 tightly into the sealing groove 28 through the pressure block 6.

[0028] The casing 1 has a glue storage tank 7 on one side, and a level gauge 21 on the glue storage tank 7 to facilitate observation of the glue capacity in the glue storage tank. The upper part of one side of the glue storage tank 7 is provided with a feed pipe 22 for adding glue into the glue storage tank, and the lower part of the glue storage tank is provided with a discharge pipe 23 for discharging waste glue. A pump body 8 is installed on the glue storage tank 7. The inlet end of the pump body 8 is connected to the glue storage tank 7 through a pipe. A first cylinder 9 is installed on the top of the glue storage tank 7. The telescopic end of the first cylinder 9 is connected to a lifting plate 27. A second cylinder 28 is installed on the lifting plate 27. A strip hole is provided on one side of the frame 4. The telescopic end of the second cylinder 28 passes through the strip hole and is connected to an L-shaped mounting plate 10. A spray pipe 11 is installed on the mounting plate 10. A nozzle 12 is connected to the lower end of the spray pipe 11. The outlet end of the pump body 8 is connected to the spray pipe 11 through a hose 13. By operating the first cylinder 9, the position of the nozzle 12 can be adjusted to adapt to sealing grooves of different diameters so that the nozzle 12 can reach above the turntable 3.

[0029] The working principle of this embodiment is as follows:

[0030] Flange 29 is placed on turntable 3. The centering mechanism centers flange 29 and clamps it to keep it stable. Then, the first cylinder 9 is extended so that nozzle 12 reaches above the sealing groove 30 on the top surface of flange. Pump body 8 is then started to draw glue from glue tank 7 and inject glue into sealing groove 30 through nozzle 12. At the same time, the drive mechanism controls the rotating column 2 to rotate, which drives turntable 3 to rotate, so that sealing groove 30 rotates around rotating column 2. Glue is injected into the entire sealing groove 30 through nozzle 12. After glue injection, sealing ring 31 is placed in sealing groove 30. Then, nozzle 12 is removed from flange 29, and hydraulic cylinder 5 is extended to drive pressure block 6 to descend. Pressure block 6 presses sealing ring 31 tightly into sealing groove 30, so that sealing ring 31 is stably fixed in sealing groove 30. After the glue dries, the assembly of sealing ring and flange is completed.

[0031] Example 2

[0032] Based on Embodiment 1, the turntable 3 is provided with multiple positioning mechanisms on its periphery, and the flange is fixed on the turntable 3 by the positioning mechanisms; the positioning mechanism includes an extension plate 24 connected to two slide plates, a third cylinder 25 installed on the two extension plates, and a pressure plate 26 connected to the telescopic ends of the two third cylinders, and the two extension plates 24 extend relative to each other.

[0033] When the slide plate 17 centers the flange, the pressure plate 26 will reach above the flange. At this time, the third cylinder 25 is extended to drive the pressure plate 26 down, which can press the edge of the flange tightly onto the turntable 3, so that the flange is further stabilized.
