Description

Technical Field

[0001] This utility model belongs to the field of cylindrical processing technology, and specifically relates to a support device for processing thin-walled cylindrical cylinders. Background Technology

[0002] Machining the ends of thin-walled cylindrical parts has always been a challenging problem. Due to the excessively thin sidewalls, the parts have poor rigidity and are prone to deformation when subjected to large radial forces. This affects the end machining of the cylindrical parts, resulting in the sample end face flatness, symmetry, and surface finish failing to meet the standards.

[0003] Especially for small cylindrical parts machined on lathes, the roundness of the cylinder can easily change due to stress during machining, thus affecting the final quality of the product. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a support device for processing thin-walled cylinders.

[0005] The technical solution adopted to solve the above technical problems is: a support device for processing thin-walled cylinders, including a mounting cylinder base and a mounting cylinder chamber. A connecting block is installed on the side of the mounting cylinder base, and an arc-shaped pressure plate is hinged to the side of the connecting block. A pressure block is installed on the inner wall of the arc-shaped pressure plate. A mounting groove is opened at one end of the top of the arc-shaped pressure plate, and a connecting plate is hinged inside the mounting groove. A manifold is installed inside the mounting cylinder chamber. One end of the manifold is connected to a rubber air bladder, and the other end of the manifold is connected to an air nozzle with a plug.

[0006] Furthermore, all the connecting blocks are arc-shaped plates and there are four of them. The four connecting blocks are arranged in a ring array on the side of the mounting base. Through the above arrangement, the distribution of the connecting blocks allows the arc-shaped pressure plate to better wrap the parts to be processed.

[0007] Furthermore, the top surface of the arc-shaped pressure plate has a groove that matches the connecting plate at the end away from the connecting plate, and magnets are installed on both the groove and the bottom surface of the connecting plate. Through the above-mentioned settings, the arc-shaped pressure plates can be stably and detachably connected by the properties of the magnets.

[0008] Furthermore, there are four rubber airbags, each a quarter-cylinder in shape. The four rubber airbags are arranged symmetrically on the manifold and extend to the outside of the mounting cylinder. With the above arrangement, the inflated airbags can effectively support the inside of the cylinder, while the uninflated airbags can be easily inserted into the cylinder by deformation.

[0009] Furthermore, a bracket is installed on the side of the mounting cylinder near the air nozzle, and a slot is provided on the side of the mounting cylinder base to match the bracket on the side of the mounting cylinder. The above-mentioned features facilitate the storage and management of the support device.

[0010] Furthermore, a through hole is provided on the side of the mounting cylinder, through which the air nozzle passes, to facilitate connection to an external device for inflation.

[0011] The beneficial effects of this invention are as follows: This invention can apply pressure evenly to the outer surface of the cylinder, avoiding structural damage caused by excessive local stress. The arc-shaped pressure plate is connected to the connecting block by a hinge, and can be stably fixed by the cooperation of the connecting plate and magnet, effectively pressing other components. The rubber airbag can change its shape and size by inflating and deflating, facilitating installation and providing effective support for the inside of the cylinder. Attached Figure Description

[0014] 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.

[0015] like Figures 1 to 4 As shown, a support device for processing thin-walled cylinders according to this embodiment includes a mounting base 1 and a mounting chamber 2. Connecting blocks 9 are mounted on the side of the mounting base 1. These connecting blocks 9 are all arc-shaped plates, and there are four of them. These four connecting blocks 9 are arranged in a circular array on the side of the mounting base 1, ensuring that the entire mounting base 1 is subjected to uniform force in all directions.

[0016] Each connecting block 9 has an arc-shaped pressure plate 3 hinged to its side. The hinged design allows the arc-shaped pressure plate 3 to rotate flexibly and adjust its flip position according to actual needs. A pressure block 4 is installed on the inner wall of the arc-shaped pressure plate 3. The surface of the pressure block 4 is smooth to ensure close contact with other components during operation, providing stable pressure without damaging the surface of the workpiece. A mounting groove is provided at one end of the top of the arc-shaped pressure plate 3, and a connecting plate 5 is hinged inside the mounting groove. Simultaneously, a groove matching the connecting plate 5 is provided at the end of the top surface of the arc-shaped pressure plate 3 away from the top surface of the connecting plate 5, and magnets are installed on both the groove and the bottom surface of the connecting plate 5. When the connecting plate 5 rotates to the position matching the groove, the magnets generate an attractive force, fixing the connecting plate 5 in the groove, thus maintaining the stability of the arc-shaped pressure plate 3 and ensuring effective pressure of the pressure block 4 on the workpiece surface.

[0017] Inside the mounting cylinder 2, a manifold 6 is installed. The manifold 6 plays a crucial role in converging and distributing fluid throughout the system. One end of the manifold 6 is connected to four rubber air bladders 7, each a quarter-cylindrical in shape. These four air bladders 7 are symmetrically arranged on the manifold 6 and extend to the outside of the mounting cylinder 2. This quarter-cylindrical design not only fully fills the internal cavity after the workpiece is machined, but also allows for uniform expansion and contraction during inflation and deflation, ensuring system stability. The rubber air bladders 7 possess good elasticity and flexibility, allowing them to change shape according to changes in internal gas pressure, thereby providing support to the inner wall of the cylinder.

[0018] The other end of the manifold 6 is connected to an air nozzle 8 with a plug. The function of the air nozzle 8 is to inflate or deflate the rubber air bladder 7, while the plug prevents gas leakage when inflation or deflation is not required. A bracket is mounted on the side of the mounting chamber 2 near the air nozzle 8, and a slot is provided on the side of the mounting base 1 to fit the bracket on the side of the mounting chamber 2. Through the cooperation of the bracket and the slot, the mounting chamber 2 can be securely mounted on the mounting base 1. A through hole is provided on the side of the mounting chamber 2 through which the air nozzle 8 passes to ensure that the air nozzle 8 can smoothly pass through the through hole and connect to the manifold 6. The working principle of this embodiment is as follows: When processing the interior of the workpiece, the mounting cylinder 2 is removed from the mounting base 1, and then the mounting base 1 is installed on the rotating shaft of the rotary head. The arc-shaped pressure plate 3 is then flipped so that it presses against the outer surface of the workpiece. During the internal processing of the workpiece, external pressure is maintained to preserve the roundness of the workpiece. After the internal processing is completed, the uninflated rubber airbag 7 on the mounting cylinder 2 is inserted into the inner cavity of the workpiece, the plug is removed, and air is inflated through the air nozzle 8, causing the rubber airbag 7 to expand and form support inside the workpiece, ensuring that the roundness of the workpiece does not easily change during the processing of the outer surface. The above description is only a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model.
