Description

Technical Field

[0001] This utility model relates to the field of hole periphery polishing technology, and in particular to a device for polishing holes in perforated metal sheets. Background Technology

[0002] Among numerous marine machinery and heavy equipment, there are various ways to connect sheet metal. Depending on the performance requirements, different connection methods are needed between sheet metal. The most common performance requirement is sealing performance, and welding is often used. However, some sheet metal can only be connected by riveting or bolting. But as long as riveting or bolting is used, punching will inevitably be produced. In order to ensure the sealing performance inside the punch, the outer surface of the punch needs to be smoothed. Then, the connector and the necessary sealing material are tightly fitted to the outer circumference of the punch. Only after the connection is pressed together can good sealing performance be guaranteed.

[0003] A search revealed a perforated metal sheet hole-peripheral polishing mechanism (authorization announcement number: CN 219837577 U). The mechanism includes a rotating assembly connected to a machine tool spindle, a fixed polishing disc, a movable polishing disc, and a push-expansion assembly. The rotating assembly includes a rotating shaft and a rotating sleeve. The fixed polishing disc includes a fixed seat, a first polishing disc, and a first grinding disc. The movable polishing disc includes a movable seat, a second polishing disc, and a second grinding disc. The push-expansion assembly includes an upper hinge seat, an elastic pull rod, and a lower hinge seat fixed to the outer ring of the rotating sleeve. This perforated metal sheet hole-peripheral polishing mechanism uses a fixed polishing disc and a movable polishing disc to clamp the sheet metal on both sides. The rotating shaft rotates at high speed after passing through the hole, driving the two polishing discs to rotate at high speed to polish the outer circumference of the perforated sheet metal. Furthermore, the movable polishing disc can expand after perforation, directly achieving simultaneous polishing of both sides of the sheet metal, doubling the polishing efficiency and improving overall polishing efficiency.

[0004] Based on the aforementioned technologies, the applicant believes that the technologies cannot simultaneously polish the inner walls and periphery of holes of different diameters, and can only polish the periphery of the holes individually, resulting in low efficiency in actual use. In response to the above problems, we have introduced a hole periphery polishing device for perforated metal sheets. Utility Model Content

[0005] This utility model discloses a hole-periphery polishing device for perforated metal sheets, which aims to solve the technical problem that it is impossible to polish the inner wall and periphery of holes of different diameters at the same time, and can only polish the periphery of the hole individually, resulting in low efficiency in actual use.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0012] In a preferred embodiment, the outer side of the grip is fixedly connected with a rubber layer for anti-slip purposes.

Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. The components of the embodiments of this application described and marked in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0023] Reference Figure 1 - Figure 4A perforated metal sheet hole circumferential polishing device includes a chassis 1. A cylinder 2 is fixedly connected to the top of the chassis 1. The telescopic end of the cylinder 2 extends to the bottom of the chassis 1 and is fixedly connected to a conical block 3. A polishing mechanism is provided on the outer side of the chassis 1. The polishing mechanism includes an adjustment component and a power component, which cooperate with each other. A fixed plate 41 is fixedly connected to the bottom of the chassis 1 in a circumferential array. A sleeve 42 is fixedly connected inside the fixed plate 41. A sliding column 43 is slidably connected inside the sleeve 42. An inner wall grinding plate 46 is fixedly connected to one end of the sliding column 43 that is far apart from each other. A hole circumferential polishing plate 47 is fixedly connected to the top of the inner wall grinding plate 46. A return spring 44 is sleeved on the outer side of the sliding column 43. A compression ball 45 is fixedly connected to one end of the sliding column 43 that is close to each other. The compression ball 45 and the conical block 3 cooperate with each other. The power assembly includes connecting columns 5, which are fixedly connected to the top of the chassis 1 in a circular array. A fixed plate 6 is fixedly connected to the top of the connecting columns 5, and a motor 7 is provided on the top of the fixed plate 6. The output end of the motor 7 is fixedly connected to the top of the fixed plate 6.

[0024] In the above technical solution, considering the inability to simultaneously grind the inner walls and periphery of holes of different diameters, and the limitation to polishing only the periphery, resulting in low efficiency in practical use, the following specific operation is performed to solve this problem:

[0025] Reference Figure 1 - Figure 4 In a preferred embodiment, the telescopic end of cylinder 2 extends downward, thereby driving the conical block 3 to move downward. The conical block 3 then presses down on four extrusion balls 45, causing the four extrusion balls 45 to move away from each other. Consequently, four sliding columns 43 slide away from each other inside the sleeve 42, causing the four inner wall polishing plates 46 to move away from each other until they are in contact with the inner wall of the hole. Then, the hole periphery polishing plate 47 is brought into contact with the top periphery of the hole. The motor 7 is then started, and its output end drives the fixed disk 6 to rotate. The fixed disk 6 drives the base plate 1 to rotate, and the base plate 1 rotates, causing the four inner wall polishing plates 46 and the four hole periphery polishing plates 47 to rotate. Through this polishing mechanism, not only can the periphery of the hole be polished, but the inner wall of the hole can also be polished simultaneously. This adapts to polishing work on holes of different sizes, improving work efficiency. The structure is simple and highly practical.

[0026] Reference Figure 1 - Figure 4In a preferred embodiment, a dust baffle 8 is fixedly connected to the top of the motor 7. A handle 9 is fixedly connected to the top of the dust baffle 8. A non-slip rubber layer is fixedly connected to the outer side of the handle 9. Both the cylinder 2 and the motor 7 are electrically connected to an external controller. The dust baffle 8 can block flying debris, preventing it from affecting workers. The rubber layer increases friction. The controller allows workers to control the opening and closing of the cylinder 2 and the motor 7. The structure is simple and highly practical.

[0027] Working principle: In actual use, the operator first holds the handle 9 and inserts the inner wall grinding plate 46 into the hole to be polished. Then, the cylinder 2 is activated, and the telescopic end of the cylinder 2 extends downward, thereby driving the conical block 3 to move downward. The conical block 3 then presses down on the four extrusion balls 45, and the four extrusion balls 45 move away from each other. Consequently, the four sliding columns 43 slide away from each other inside the sleeve 42, thereby moving the four inner wall grinding plates 46 away from each other until the four inner wall grinding plates 46 are in contact with the inner wall of the hole. Then, the hole periphery polishing plate 47 is made to fit against the top and periphery of the hole. Then, the motor 7 is activated, and the output end of the motor 7 drives the fixed plate 6 to rotate. The fixed plate 6 drives the base plate 1 to rotate, and the rotation of the base plate 1 drives the four inner wall grinding plates 46 and the four hole periphery polishing plates 47 to rotate, thus beginning the grinding and polishing of the inner wall and periphery of the hole.

The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
