Description

Technical Field

[0001] The utility model relates to the technical field of antenna cover clamping, in particular to a clamping mechanism for antenna cover processing. Background Art

[0002] The radome is a structure that protects the antenna system from the external environment. It prevents the antenna from being attacked by rain and solar radiation in nature when working outdoors, which would reduce the antenna's accuracy, shorten its life and cause poor working reliability. The radome is mostly a cylindrical structure with a hollow interior. During processing, the inner wall surface needs to be cleaned, polished and other treatments to improve its surface smoothness and reduce the corrosion rate.

[0003] After searching, Chinese patent CN220128219U was found and announced, which is a clamping mechanism for the production and processing of antenna covers.

It can be seen that this patent realizes the clamping and fixing of multiple antenna covers of the same specification or multiple antenna covers of different specifications, and a large part of the shape of the antenna cover is spherical, so that the concave surface of the clamping seat in the patent cannot effectively clamp the shape of the antenna cover firmly. For this reason, a clamping mechanism for antenna cover processing is proposed. Utility Model Content

The movable seat 81 is slidably connected to the opposite side of the top plate 1 and the bottom plate 2, and a slide rail 9 slidably connected to the movable seat 81 is fixedly installed on the opposite side of the top plate 1 and the bottom plate 2. The movable seat 81 slides laterally on the outer surface of the slide rail 9. The cross-sectional shape of the slide rail 9 is T-shaped. Limiting blocks corresponding to the movable seat 81 are fixedly installed at both ends of the slide rail 9 to prevent the movable seat 81 from moving out of the slide rail 9 and play a limiting role. The hydraulic cylinder 82 is fixedly installed on the top of the bottom plate 2, and the output end of the hydraulic cylinder 82 is fixedly installed on the movable seat 81 at the bottom. The hydraulic cylinder 82 is retracted to push the movable seat 81 to move laterally.

[0026] In addition, the first movable rod 83 is hinged between the bottom movable seat 81 and the top plate 1, and the second movable rod 84 is hinged between the top movable seat 81 and the bottom plate 2. The lengths of the first movable rod 83 and the second movable rod 84 are equal. The connecting rod 85 is arranged between the first movable rod 83 and the second movable rod 84. The movable seat 81 moves, and under the connection of the connecting rod 85 to the first movable rod 83 and the second movable rod 84, the first movable rod 83 and the second movable rod 84 move to gradually lift or drop the top plate 1, thereby realizing the lifting and lowering of the top plate 1, which is convenient for workers to place the antenna cover workpiece 3 on the top plate 1.

[0027] See also Figure 1-3 A clamping assembly 6 for clamping the antenna cover workpiece 3 is arranged on the fixed seat 4 and the mounting seat 5. The clamping assembly 6 includes a cylinder 61, a rack 62, a connecting shaft 63, a driving gear 64, a transmission gear 65 and a clamping rod 66. The cylinder 61 is fixedly mounted on the side wall of the mounting seat 5, and the rack 62 is fixedly mounted on the output end of the cylinder 61. The extension and retraction of the cylinder 61 can allow the rack 62 to move. A guide rail 7 slidably connected to the rack 62 is fixedly mounted on the top of the top plate 1. The guide rail 7 supports and guides the rack 62, allowing the rack 62 to move along the outer surface of the guide rail 7. The cross-sectional shape of the guide rail 7 is T-shaped.

[0028] In addition, the connecting shaft 63 is rotatably connected in the fixed seat 4, the axis of the connecting shaft 63 is not located in the center of the antenna cover workpiece 3, and the driving gear 64 is fixedly installed at one end of the connecting shaft 63. The driving gear 64 can rotate along the connecting shaft 63, and the rack 62 is meshed with the driving gear 64. The movement of the rack 62 can push the driving gear 64 to rotate along the axis of the connecting shaft 63. Both ends of the top of the rack 62 are fixedly connected with blocks corresponding to the driving gear 64, so that the rack 62 and the driving gear 64 are always in a meshing state.

[0029] At the same time, the transmission gear 65 is fixedly installed on the outer surface of the connecting shaft 63. The transmission gear 65 can rotate with the connecting shaft 63. The transmission gear 65 is externally meshed with the transmission gear 65. The number of the fixed seat 4, the connecting shaft 63 and the transmission gear 65 is four. The clamping rod 66 is fixedly installed between the opposite sides of the connecting shafts 63 on both sides. The uppermost position of the antenna cover workpiece 3 is higher than the uppermost position when the clamping rod 66 moves to a vertical state, which is beneficial for the clamping rod 66 to clamp the antenna cover workpiece 3. The two transmission gears 65 are meshed with each other so that the clamping rods 66 on both sides are close to each other to clamp the spherical surface of the antenna cover workpiece 3, or separate from each other to take out the antenna cover workpiece 3 from between the clamping rods 66 on both sides. The shape of the clamping rod 66 is arc-shaped, which can be adapted to the spherical surface of the antenna cover workpiece 3.

[0030] When this embodiment is in use, the antenna cover workpiece 3 is placed on the top plate 1, and then the cylinder 61 is started, the rack 62 moves, and the driving gear 64 rotates due to meshing. Under the mutual external meshing transmission of the transmission gears 65, the clamping rods 66 on both sides rotate to approach each other and gradually abut against the spherical surface of the antenna cover workpiece 3, thereby completing the clamping work of the antenna cover workpiece 3.

[0031] The beneficial effects of the above embodiments are:

[0032] The clamping mechanism for antenna cover processing is provided with a clamping assembly 6. The clamping assembly 6 uses the rear rack 62 to move, and the driving gear 64 rotates due to the meshing. Under the mutual meshing transmission of the transmission gear 65, the arc-shaped clamping rods 66 on both sides move toward each other, gradually approaching and contacting the spherical surface of the antenna cover workpiece 3. At this time, the antenna cover workpiece 3 is abutted by the two clamping rods 66 above and supported by the top plate 1, thereby effectively clamping the spherical outer surface of the antenna cover workpiece 3.

[0033] In addition, by setting up a lifting component 8, the lifting component 8 allows the movable seat 81 to move after use. Under the mutual movement of the first movable rod 83 and the second movable rod 84 and the connection of the connecting rod 85, the top plate 1 can be lifted or lowered, which is convenient for workers to place the antenna cover workpiece 3 on the top plate 1.
