[0022] See Figures 1 - 4, this embodiment provides a large aluminum block blank fixing fixture, including a base 1, on which a clamping device 2 is provided. The clamping device 2 includes a support rod 21, the support rod 21 is fixedly connected to the bottom of the inner wall of the base 1, the top of the support rod 21 is fixedly connected with a fixed block 22, the right side of the fixed block 22 is fixedly connected with a sliding rod 212, the outer wall of the sliding rod 212 is slidably connected with a slider 23, the top of the slider 23 is fixedly connected with a clamping rod 24, the top of the support rod 21 is rotatably connected with a circular gear 25 through a bearing, the front of the clamping rod 24 is fixedly connected with a collar 26, and a rack 27 is fixedly connected to the inner wall of the collar 26. The circular gear 25 and the rack 27 mesh with each other, and the right side of the rack 27 is slidably connected to the inner wall of the right collar 26. A chute 28 is opened at the top of the support rod 21, a connecting rod 211 is slidably connected to the chute 28, the top of the inner wall of the support rod 21 is fixedly connected with a hydraulic cylinder 29 through a connecting block 210, the right side of the output end of the hydraulic cylinder 29 is fixedly connected to the front of the connecting rod 211, and the top of the connecting rod 211 is fixedly connected to the bottom of the right slider 23. A moving groove is opened at the top of the base 1, and the clamping rod 24 is slidably connected to the inner wall of the moving groove.

[0023] When the above equipment is specifically used, by starting the hydraulic cylinder 29, the output end of the hydraulic cylinder 29 drives the connecting rod 211 to move to the left. The connecting rod 211 drives the right slider 23 to slide on the outer wall of the right sliding rod 212. The right slider 23 drives the right clamping rod 24 and the clamping block 4 to move to the left. The left side of the rack 27 on the front is fixedly connected to the inner wall of the left collar 26. The right clamping rod 24 drives the rack 27 on the back to slide in the inner wall of the left collar 26. At the same time, the rack 27 on the back drives the circular gear 25 to rotate counterclockwise during the sliding. The rotation of the circular gear 25 drives the rack 27 on the front to move to the right. The rack 27 on the front drives the left clamping rod 24 to move to the right, realizing the relative movement of the two clamping rods 24 driving the two clamping blocks 4.

Embodiment

[0024] See Figures 1 - 4, on the basis of the first embodiment, an installation device 3 is provided on the base 1. The installation device 3 includes a limit block 32 which is slidably connected to the top of the clamping rod 24. A clamping block 4 is fixedly connected to the left side of the clamping rod 24. A through hole 34 is formed in the left side of the clamping rod 24, and a plug rod 33 is inserted into the inner wall of the through hole 34. A limit plate 31 is fixedly connected to the top of the base 1, and the clamping rod 24 is slidably connected to the outer wall of the limit plate 31. The limit plate 31 is cast in an integrated manner, which improves the integrity, has no interfaces inside, does not have the weakness problems at the interfaces, does not require assembly, can be directly installed, is convenient for production, manufacturing and maintenance, reduces the number of parts and steps in the assembly process, reduces the assembly cost and time, reduces the connection points and joints, reduces the risk of loosening or failure between parts, enhances the structural strength and stability of the overall component, and improves the long-term service life of the product.

[0025] When the above-mentioned device is specifically used, when it is necessary to replace the clamping block 4 with a different shape, the plug rod 33 is removed, so that the limit block 32 slides out from the inner wall of the clamping rod 24, and the clamping block 4 with another shape is replaced. At the same time, the limit plate 31 makes the clamping rod 24 more stable when moving. After removing the plug rod 33 and removing the limit block 32, the clamping block 4 with different shapes can be quickly replaced. This design simplifies the replacement process, improves the flexibility and efficiency of operation. The setting of the limit plate 31 ensures that the clamping rod 24 is more stable when moving, and reduces the vibration or deviation caused by the movement of the clamping rod 24. This improves the fixing accuracy and reliability of the clamping block 4.
