Abstract
Description
Technical Field
[0001] This utility model relates to the field of cylinder machining technology, and in particular to a support device for machining the inner and outer circles of a cylinder. Background Technology
[0002] Cylinder internal and external cylindrical machining is a precision machining method widely used in the machinery manufacturing industry. It is mainly used to machine the inner and outer cylindrical surfaces of various shafts, sleeves, and discs. This machining method has advantages such as high precision, high production efficiency, and simple operation. Therefore, it has been widely used in industries such as aviation, aerospace, automotive, and machine tools. During cylinder internal and external cylindrical machining, a support device is required to ensure the stability and precision of the cylinder.
[0003] A cylinder inner and outer circle machining support device is disclosed in Chinese Patent Publication No. CN220480901U. This cylinder inner and outer circle machining support device, by setting an outer support block, a clamping mechanism, an inner support block and a U-shaped connecting rod, enables the device to clamp the inner and outer circles of the cylinder part, which facilitates the machining of the inner and outer circles. The inner and outer circle clamping components are concentrated in one place, making the clamping operation more convenient and faster.
[0004] However, compared with existing technologies in related fields, there will theoretically be a certain gap between the meshing of gears and racks. This gap is mainly to ensure that the gears and racks will not jam due to thermal expansion or other factors during operation. Therefore, the gap will reduce the transmission accuracy between the gears and racks, affecting the accuracy of motion and repeatability, which will affect the stability of machining the inner and outer circles of the cylinder. Furthermore, the cylinder needs to be rotated and adjusted during machining, but existing equipment requires first releasing the clamping state of the cylinder and then operating the hoisting equipment to rotate and adjust its position. This makes the adjustment process cumbersome and affects the processing efficiency. Utility Model Content
[0005] The purpose of this utility model is to overcome the shortcomings of the prior art, solve the problems mentioned in the background art, and provide a support device for machining the inner and outer circles of a cylinder.
[0006] The purpose of this utility model is achieved through the following technical solution: a support device for machining the inner and outer circles of a cylinder, including a mounting plate, two support components symmetrically arranged on the top of the mounting plate, the support components including a fixed ring fixedly installed on the top of the mounting plate, four movable rods hinged at equal intervals on the outer surface of the fixed ring, and a rolling assembly rotatably provided at the end of each of the four movable rods away from the hinged end with the fixed ring.

The movable ring is slidably connected to the mounting plate by a sliding assembly. A cylinder for controlling the sliding of the movable ring is fixedly installed on the top of the mounting plate. When the movable ring slides towards the side of the fixed ring, the connecting rod will control the ends of the four movable rods to move closer to each other. When the movable ring slides away from the side of the fixed ring, the connecting rod will control the ends of the four movable rods to move away from each other.
[0007] Preferably, the fixed ring has a first movable groove at the position of each of the four movable rods, and the four movable rods are hinged to the first movable grooves through a rotating shaft.
[0008] Preferably, the rolling assembly includes a pin fixedly mounted on the end of the movable rod, and a hard disk and a floppy disk are rotatably mounted on the outer surface of the pin, with the hard disk and floppy disk being fixedly connected.
[0009] Preferably, the outer surfaces of both the hard disk and the floppy disk are formed with arc surfaces, and the positions of the pins on both the hard disk and the floppy disk are provided with rotating holes, with bearings embedded inside the rotating holes of the hard disk.

[0013] Beneficial effects:
[0014] This internal and external cylindrical machining support device, through the setting of a support component and a rolling component, firstly, utilizes the support component to achieve support and limit the rolling component for various cylindrical bodies, while ensuring that there are no gaps between the movable ring, movable rod, and connecting rod after the limit is set, effectively ensuring the stability of the internal and external cylindrical machining. Secondly, the rolling component utilizes the deformation of the floppy disk to achieve self-locking of the hard disk and floppy disk, further ensuring the stability of the cylindrical body during machining, while also allowing the part of the floppy disk in contact with the cylindrical body to return to its normal state, so that the hard disk and floppy disk can rotate, thereby facilitating the rotation of the cylindrical body for position adjustment.

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] Additional aspects and advantages of this invention will be further set forth in the description which follows in conjunction with the accompanying drawings, and in part will be obvious from the description or may be learned by practice of the invention.
[0025] like Figures 1 to 6 As shown, a support device for machining the inner and outer circles of a cylinder includes a mounting plate 1. Two support components 2 are symmetrically arranged on the top of the mounting plate 1. Each support component 2 includes a fixed ring 21 fixedly mounted on the top of the mounting plate 1. Four movable rods 22 are hinged at equal intervals on the outer surface of the fixed ring 21. A rolling assembly 3 is rotatably provided at the end of each of the four movable rods 22 away from the hinged end with the fixed ring 21. A movable ring 23 is provided on the side of the mounting plate 1 near the fixed ring 21. The movable ring 23 is connected to the movable rods 22 via a connecting rod 24. The movable ring 23 slides against the mounting plate 1 via a sliding assembly 4. The movable connection is achieved by fixing a cylinder 5 on the top of the mounting plate 1 to control the sliding of the movable ring 23. When the movable ring 23 slides to one side of the fixed ring 21, the connecting rod 24 controls the ends of the four movable rods 22 to move closer to each other. When the movable ring 23 slides away from the fixed ring 21, the connecting rod 24 controls the ends of the four movable rods 22 to move away from each other. By utilizing the mechanical cooperation between the movable ring 23, the movable rods 22 and the connecting rod 24, the transmission gap can be avoided, effectively ensuring the transmission accuracy of the device and improving the stability of the inner and outer cylinders during machining.
[0026] As a preferred technical solution of this utility model, such as Figure 4 As shown, the fixed ring 21 has a first movable groove 211 at the position corresponding to the four movable rods 22, and the four movable rods 22 are all hinged to the first movable groove 211 through a rotating shaft.
[0027] As a preferred technical solution of this utility model, such as Figures 3 to 6 As shown, the rolling assembly 3 includes a pin 31 fixedly installed at the end of the movable rod 22. A hard disk 32 and a floppy disk 33 are rotatably mounted on the outer surface of the pin 31. The hard disk 32 and the floppy disk 33 are fixedly connected. The outer surfaces of the hard disk 32 and the floppy disk 33 are both formed with arc surfaces. Rotation holes are opened on the hard disk 32 and the floppy disk 33 at the positions corresponding to the pin 31. A bearing is embedded in the rotation hole of the hard disk 32. By using the bearing, the friction force when the hard disk 32 rotates can be reduced, and the stability of the hard disk 32 during rotation can be improved. At the same time, the deformation of the floppy disk 33 can achieve self-locking of the hard disk 32 and the floppy disk 33, further ensuring the stability of the cylinder during processing. At the same time, it can also allow the part of the floppy disk 33 in contact with the cylinder to return to normal. Then the hard disk 32 and the floppy disk 33 can rotate, thereby facilitating the rotation of the cylinder for position adjustment.
[0028] As a preferred technical solution of this utility model, such as Figure 4 As shown, the movable ring 23 is provided with a second movable groove 231 at the end of the connecting rod 24, and the movable rod 22 is provided with a third movable groove 221 at the end of the connecting rod 24. The connecting rod 24 is hinged to the second movable groove 231 and the third movable groove 221 through a rotating shaft.
[0029] As a preferred technical solution of this utility model, the sliding component 4 includes a slide rail 41 fixedly installed below the movable ring 23, and a slider 42 adapted to the slide rail 41 is fixedly provided at the bottom of the outer surface of the movable ring 23. The output end of the cylinder 5 is fixedly installed with the slider 42.
[0030] As a preferred technical solution of this utility model, such as Figures 2 to 4 As shown, both the fixed ring 21 and the movable ring 23 have notches 6 above them. The notches 6 facilitate the insertion and removal of the cylinder from the fixed ring 21 and the movable ring 23.
[0031] The work process is as follows:
[0032] S1, such as Figure 1 , Figure 2 and Figure 4 As shown, during use, the cylinder 5 controls the slider 42 to slide inside the slide rail 41 (at this time, the output end of the cylinder 5 is in the extended state), and then the slider 42 will drive the movable ring 23 to slide to one side of the fixed ring 21.
[0033] S2, such as Figures 2 to 4 As shown, when the movable ring 23 slides to one side of the fixed ring 21, the connecting rod 24 will control the ends of the four movable rods 22 to move closer to each other. At this time, the cylinder can be placed inside the fixed ring 21 and the movable ring 23 through the notch 6.
[0034] S3, such as Figures 2 to 5 As shown, when the cylinder is placed inside the fixed ring 21 and the movable ring 23, the two floppy disks 33 located below will support the cylinder in advance. At this time, the movable ring 23 can be controlled to slide to one side of the fixed ring 21, so that the other two floppy disks 33 press down on the cylinder.
[0035] S4, such as Figure 2 , Figure 5 and Figure 6 As shown, after the cylinder is supported and pressed by the four floppy disks 33, the movable ring 23 can still be controlled to slide towards the side of the fixed ring 21. The connecting rod 24 will control the ends of the four movable rods 22 to move away from each other, so that the parts of the four floppy disks 33 that contact the cylinder will deform. Then the inner walls of the four floppy disks 33 will tightly fit the pin 31, thereby realizing the self-locking of the hard disk 32 and the floppy disk 33, ensuring the stability of the cylinder during processing.
[0036] S5, such as Figures 2 to 6As shown, when the cylinder needs to be rotated, the cylinder 5 controls the slider 42 to slide inside the slide rail 41 (at this time, the output end of the cylinder 5 gradually retracts). Then, the slider 42 will drive the movable ring 23 to slide away from the fixed ring 21, so that the parts of the four floppy disks 33 that are in contact with the cylinder gradually return to normal. At this time, the hard disk 32 and the floppy disk 33 will release the self-locking state, and then the hard disk 32 and the floppy disk 33 can rotate, thereby rotating the cylinder for adjustment.
[0037] S6, such as Figures 1 to 6 As shown, after the cylinder body is processed, the cylinder 5 controls the slider 42 to slide inside the slide rail 41 (at this time, the output end of the cylinder 5 gradually retracts). Then, the slider 42 will drive the movable ring 23 to slide away from the fixed ring 21. The connecting rod 24 will control the ends of the four movable rods 22 to move away from each other. At this time, the cylinder body can be taken out from inside the fixed ring 21 and the movable ring 23.
[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
