Detailed Implementation

[0019] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0020] like Figure 1-3 As shown, this utility model provides a technical solution: a pneumatic clamping device for anchorages, including a connecting seat 1, a placement platform 2 on the connecting seat 1, the connecting seat 1 and the placement platform 2 are hollow, and a pneumatic telescopic rod 3 is installed inside the connecting seat 1. A rack 17 is connected to the movable end of the pneumatic telescopic rod 3. The rack 17 slides inside the connecting seat 1 and contacts the inner wall of the connecting seat 1. The rack 17 is meshed with a gear 8. By activating the pneumatic telescopic rod 3, the rack 17 is pushed to move inside the connecting seat 1. Due to the meshing connection between the rack 17 and the gear 8, the connecting rod 4 and the rotating disk 9 can rotate, thereby driving the clamping plate 12 to move and clamp and fix the anchorage. The contact between the inner wall of the connecting seat 1 and the rack 17 can limit the rack 17, so that the rack 17 can move smoothly and prevent the rack 17 from deflecting.

[0021] A connecting rod 4 is rotatably connected inside the connecting seat 1. A threaded rod 5 is threadedly connected to the connecting seat 1. One end of the threaded rod 5 is connected to a rotating wheel 6, and the other end of the threaded rod 5 is rotatably connected to a positioning plate 7. An anti-slip pad 18 is connected above the positioning plate 7, and sliding rods 19 are connected to both sides below the positioning plate 7. The sliding rods 19 are slidably connected to the connecting seat 1. The threaded rod 5 pushes the positioning plate 7 to contact the workbench. At this time, the anti-slip pad 18 will be squeezed and deformed, thus making it fit against the workbench to increase friction, prevent slippage, and improve the stability of the fixation. The sliding rods 19 can guide the movement of the positioning plate 7, thereby preventing the positioning plate 7 from rotating or tilting.

[0022] A gear 8 is connected to the connecting rod 4, and a rotating disk 9 is connected to one end of the connecting rod 4. Two sliding grooves 10 are opened on the rotating disk 9. A sliding block 11 is slidably connected in the sliding groove 10. The sliding block 11 slides in the guide groove 13. Limiting blocks 15 are connected to both sides of the sliding block 11. When the rotating disk 9 rotates, the sliding groove 10 will push the sliding block 11, causing the sliding block 11 to slide in the sliding groove 10 and the guide groove 13. Thus, the guide groove 13 guides the movement of the sliding block 11 and the clamping plate 12.

[0023] A clamping plate 12 is connected to the sliding block 11. A fixing groove 14 is provided on the clamping plate 12. The fixing groove 14 is V-shaped, and the connecting seat 1 is J-shaped. By moving the two clamping plates 12 in opposite directions, the anchor placed on the placement platform 2 is clamped and fixed to prevent the anchor from sliding and shifting during processing.

[0024] The placement platform 2 has guide grooves 13 on both sides, and limit grooves 16 are provided on the groove walls on both sides of the guide grooves 13. The limit block 15 is T-shaped and slides in the limit groove 16. When the sliding block 11 moves along the guide groove 13, the limit block 15 will slide in the limit groove 16, thereby limiting and guiding the movement of the clamping plate 12 and preventing the clamping plate 12 from rotating and tilting.

[0025] The working principle of this utility model is as follows:

[0026] The operator places the connecting seat 1 on the workbench with the bent part of the connecting seat 1 close to the edge of the workbench. Then, the rotating wheel 6 rotates the threaded rod 5, causing the threaded rod 5 to push the positioning plate 7 to move. At the same time, the sliding rod 19 slides synchronously on the connecting seat 1, thereby guiding and restricting the movement of the positioning plate 7 and preventing the positioning plate 7 from rotating or tilting during the movement. This allows the positioning plate 7 to contact the workbench, while the anti-slip pad 18 is squeezed and deformed, thus making contact with the table to increase friction and prevent slippage. This allows the positioning plate 7 to clamp the table and fix the connecting seat 1. Then, the anchor is placed on the placement platform 2, and the pneumatic telescopic rod 3 is activated to push the rack 17 to move. The meshing of the rack 17 and the gear 8 drives the connecting rod 4 and the rotating disk 9 to rotate. As the rotating disk 9 rotates, the sliding groove 10 pushes the sliding block 11, causing the sliding block 11 to move along the guide groove 13. This causes the two sliding blocks 11 to drive the two clamping plates 12 to move in opposite directions, causing the clamping plates 12 to clamp and fix the processing anchor for processing operations.
