Description

Technical Field

[0001] This utility model relates to the field of flap wheel technology, and in particular to a flap wheel that can improve overall strength. Background Technology

[0002] A flap wheel is a coated abrasive tool, typically used in conjunction with various automatic, electric, and manual grinding and polishing machines for grinding and polishing operations. It is a safe, efficient, one-piece molded abrasive wheel. With its unique structure and material composition, the flap wheel plays an important role in the grinding and polishing field and is therefore widely used in automobile manufacturing, ship repair, heavy machinery, aluminum alloys, stainless steel and other fields.

[0003] Currently, existing flap wheels often suffer from insufficient overall strength due to design or material selection issues. Traditional flap wheel designs may lack adequate protective structures, making them prone to deformation, breakage, or blade slippage. This can cause the abrasive pads to shift or deform under significant pressure. Furthermore, existing protective structures are often fixed with bolts. Over long-term use, this method can lead to bolt stripping and structural misalignment, reducing the protective effect of the structure. Therefore, we propose a flap wheel with improved overall strength to address these problems. Utility Model Content

[0004] The purpose of this invention is to provide a flap wheel that improves overall strength, solving the problem that traditional flap wheel designs in the prior art may lack sufficient protective structure, making the flap wheel prone to deformation, breakage, or blade slippage. This causes the abrasive cloth to easily shift or deform under high pressure, and existing protective structures are often fixed with bolts. However, this method is prone to bolt stripping and structural misalignment during long-term use, reducing the protective effect of the structure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A flapper wheel with improved overall strength includes a flapper wheel body. Sleeves are vertically symmetrically arranged inside the flapper wheel body. Each sleeve has a mounting plate inside. Each sleeve has a buffer assembly connected to an adjacent mounting plate inside. A pressing plate is provided on the other side of each mounting plate. Two protrusions are symmetrically fixedly connected to the outside of each pressing plate. Each sleeve has a mounting ring inside, and the outside of the mounting ring is fixedly connected to the inner wall of the sleeve. A groove adapted to the two adjacent protrusions is formed on one side surface of each mounting ring. A protective ring is provided on the side of each pressing plate away from the mounting plate.

[0007] Preferably, the buffer assembly includes two damping rods symmetrically arranged inside the sleeve. Both ends of the two damping rods are fixedly mounted with fixing plates. The side of each fixing plate away from the damping rod is fixedly connected to the adjacent side wall of the mounting plate, and the side of the other two fixing plates away from the damping rod is fixedly connected to the inner wall of one side of the sleeve.

[0008] Preferably, the buffer assembly further includes springs sleeved on the outside of the two damping rods, with both ends of the two springs fixedly connected to the adjacent sidewalls of the two adjacent fixed plates.

[0009] Preferably, the two mounting rings have two slots symmetrically formed on the side surface near the mounting plate, and each of the two protrusions has a plug that matches the slot fixedly connected to the side near the mounting ring.

[0010] Preferably, the two protective rings are fixedly connected in a ring array to a plurality of connecting rods on the side surface near the adjacent pressing plate, and the ends of the plurality of connecting rods away from the protective rings are fixedly connected to the adjacent side wall of the adjacent pressing plate.

[0011] Preferably, the outer sides of both sleeves are fixedly connected to the inner annular wall of the flap wheel body, and mounting holes are provided through one side of each of the two pressing plates, one side of each of the two mounting plates, and one side of each of the sleeves.

[0012] This utility model has at least the following beneficial effects:

[0013] The protective ring protects the flapper wheel body from deformation of the abrasive cloth. A connecting rod secures the protective ring to the sleeve, allowing the force exerted on the protective ring by the external environment to be transmitted through the connecting rod and then through the pressing plate and mounting plate to the damping rod and spring, thus buffering the external force and reducing the stress on the protective ring, significantly improving the overall strength of the flapper wheel. This design enables the flapper wheel to maintain a stable shape and performance even under significant pressure.

[0014] This utility model also has the following beneficial effects:

[0015] Press the pressure plate against the mounting plate, aligning the protrusion with the groove and pushing it between the mounting ring and the mounting plate. Then rotate the pressure plate to engage the two inserts with the slots, positioning the pressure plate and mounting ring. Release the pressure plate, allowing the two springs to spring back and push the mounting plate against the pressure plate and mounting ring, thus positioning the protective ring and enabling quick installation and removal of the protective structure. This not only reduces operational difficulty and time costs but also minimizes damage to the flapper wheel itself. The convenient installation and removal method makes maintenance and replacement of the protective structure of the flapper wheel easier and faster, improving efficiency and reducing maintenance costs.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0024] Reference Figure 1-5A flapper wheel with improved overall strength includes a flapper wheel body 1. Inside the flapper wheel body 1, sleeves 2 are vertically symmetrically arranged. Each sleeve 2 has a mounting plate 8 inside. Each sleeve 2 has a buffer assembly connected to an adjacent mounting plate 8 inside. A pressing plate 6 is provided on the other side of the mounting plate 8. Two protrusions 12 are symmetrically fixedly connected to the outside of the pressing plate 6. Each sleeve 2 has a mounting ring 3 inside, and the outside of the mounting ring 3 is fixedly connected to the inner wall of the sleeve 2. One side surface of the mounting ring 3 has a groove that matches the two adjacent protrusions 12. Each pressing plate 6 has a protective ring 4 on the side away from the mounting plate 8. Specifically, the protective ring 4 protects the outside of the flapper wheel body 1, preventing deformation of the abrasive cloth on the flapper wheel body 1. The protective ring 4 is connected to the sleeve via a connecting rod 5. The fixed connection allows the force exerted on the protective ring 4 by the external environment to be transmitted through the connecting rod 5 and then through the pressing plate 6 and mounting plate 8 to the damping rod 9 and spring 10, thus buffering the external force, reducing the force on the protective ring 4, improving the overall strength of the flapper, and facilitating subsequent use. The pressing plate 6 is pressed against the mounting plate 8, aligning the protrusion 12 with the groove and pushing it between the mounting ring 3 and the mounting plate 8. Then, the pressing plate 6 is rotated so that the two inserts 7 engage with the slots, positioning the pressing plate 6 and the mounting ring 3. Releasing the pressing plate 6 allows the two springs 10 to elastically return, pushing the mounting plate 8 to press against the pressing plate 6 and abut against the mounting ring 3, thus positioning the protective ring 4. This achieves convenient installation and removal of the protective ring 4. The use of a quick-release assembly enables rapid installation and removal of the protective ring 4. This not only reduces operational difficulty and time costs but also minimizes damage to the flapper itself. The convenient installation and removal method makes maintenance and replacement of the protective structure of the flapper easier and faster, improving efficiency and reducing maintenance costs.

[0025] Furthermore, the buffer assembly includes two damping rods 9 symmetrically arranged inside the sleeve 2. Each end of the two damping rods 9 is fixedly mounted with a fixing plate 11. The side of each fixing plate 11 furthest from the damping rod 9 is fixedly connected to the adjacent side wall of the mounting plate 8, while the side of the other two fixing plates 11 furthest from the damping rod 9 is fixedly connected to the inner wall of one side of the sleeve 2. Specifically, through the arrangement of the damping rods 9, the damping rods 9 can work in conjunction with the spring 10 to provide a better buffering effect, enabling the sleeve 2 to provide better protection for the flapper body 1 with the protective ring 4, thus providing higher overall strength for the use of the flapper body 1.

[0026] Furthermore, the buffer assembly also includes springs 10 sleeved on the outside of the two damping rods 9. Both ends of the two springs 10 are fixedly connected to the adjacent side walls of the two adjacent fixing plates 11. Specifically, through the setting of the fixing plates 11, the fixing plates 11 can fix the damping rods 9 to the mounting plate 8, so that the mounting plate 8 is stably located inside the sleeve 2.

[0027] Furthermore, two slots are symmetrically opened on the surface of the two mounting rings 3 near the mounting plate 8. Each of the two protrusions 12 near the mounting ring 3 is fixedly connected to a plug 7 that matches the slot. Specifically, through the setting of the plug 7 and the slot, the operator can press the pressing plate 6 into the mounting plate 8 inside the sleeve 2. At this time, the mounting plate 8 presses the damping rod 9 and the spring 10. By aligning the two protrusions 12 on the outside of the pressing plate 6 with the two grooves of the mounting ring 3 and pushing them between the mounting ring 3 and the mounting plate 8, the pressing plate 6 is then rotated so that the plug 7 on one side of the two protrusions 12 is inserted into the slot on one side of the mounting ring 3, thereby positioning the pressing plate 6 and the mounting ring 3. By releasing the pressing plate 6, the two springs 10 lose their compressive force and elastically recover, pushing the mounting plate 8 to press the pressing plate 6, so that the pressing plate 6 abuts against the mounting ring 3, thereby achieving the effect of convenient installation and removal of the protective ring 4. By adopting an innovative positioning method, the protective ring 4 is accurately positioned and fixed. This design ensures the stability and reliability of the protective ring 4 during long-term use.

[0028] Furthermore, multiple connecting rods 5 are fixedly connected in a ring array on the surface of the two protective rings 4 near the adjacent pressing plate 6. The ends of the connecting rods 5 away from the protective rings 4 are all fixedly connected to the adjacent sidewalls of the adjacent pressing plate 6. Specifically, the protective rings 4 and connecting rods 5 increase the overall strength of the device. The protective rings 4 protect the exterior of the flapper wheel body 1, preventing deformation of the abrasive cloth on the flapper wheel body 1. The connecting rods 5 fix the protective rings 4 to the sleeve 2, allowing the protective rings 4 to transmit the force from the external environment through the connecting rods 5. The connecting rods 5 transmit the force through the pressing plate 6 and mounting plate 8 to the damping rod 9 and spring 10, buffering the external force and reducing the force on the protective rings 4. This improves the overall strength of the flapper wheel, facilitating subsequent use. By introducing a reinforcing structure to support and fix the flapper wheel, the overall strength of the flapper wheel is significantly improved. This design allows the flapper wheel to maintain a stable shape and performance even under significant pressure.

[0029] Furthermore, the outer sides of both sleeves 2 are fixedly connected to the inner ring wall of the flap wheel body 1. The inner walls of the two pressing plates 6, the two mounting plates 8, and the two sleeves 2 are all provided with mounting holes. Specifically, the mounting holes facilitate the installation of the flap wheel body 1 on the working position of the polishing machine for subsequent grinding of the material.

[0030] In summary:

[0031] By setting the protective ring 4 and the connecting rod 5, the overall strength of the device can be increased. The protective ring 4 protects the outside of the flap wheel body 1, preventing the abrasive cloth on the flap wheel body 1 from deforming. The connecting rod 5 fixes the protective ring 4 to the sleeve 2, allowing the protective ring 4 to transmit the force from the external environment through the connecting rod 5. The connecting rod 5 transmits the force to the damping rod 9 and the spring 10 through the pressing plate 6 and the mounting plate 8, buffering the external force and reducing the force on the protective ring 4. This improves the overall strength of the flap wheel and facilitates subsequent use.

[0032] Pressing the pressing plate 6 against the mounting plate 8 inside the sleeve 2 causes the mounting plate 8 to press against the damping rod 9 and the spring 10. By aligning the two protrusions 12 on the outside of the pressing plate 6 with the two grooves of the mounting ring 3 and pushing them between the mounting ring 3 and the mounting plate 8, the pressing plate 6 is then rotated so that the insert 7 on one side of the two protrusions 12 is inserted into the slot on one side of the mounting ring 3, thereby positioning the pressing plate 6 and the mounting ring 3. By releasing the pressing plate 6, the two springs 10 lose their compressive force and elastically recover, pushing the mounting plate 8 to press against the pressing plate 6, causing the pressing plate 6 to abut against the mounting ring 3, thus achieving the effect of convenient installation and removal of the protective ring 4.
