[0002] Precision metal parts are a common type of mechanical parts. They use modern technologies such as high-precision metal forming technology, precision testing, and automation to process metal materials into metal parts of predetermined design shapes or sizes. They have the characteristics of high processing accuracy, small dimensional tolerance, high surface finish, and other precision features.

[0023] In order to solve the problem that the correction tool is not convenient for fixing metal parts of different shapes, when it is necessary to fix square metal parts, the two groups of hydraulic cylinders 3 can be started to make the two groups of hydraulic cylinders 3 push the two groups of first clamping plates 4 to move toward the center of the correction platform 1 at the same time. When the square grooves at the centers of the two groups of first clamping plates 4 move to the outer wall of the square metal parts, the square metal parts can be clamped and fixed, thereby facilitating the correction of the square metal parts. When it is necessary to fix round or arc-shaped metal parts, the threaded rod 6 can be rotated to make the threaded rod 6 rotate on the inner wall of the nut 9 and gradually move toward the first clamping plate 1. The inner wall of the plate 4 moves, so that the second clamping plate 5 can be pushed to one side through the rotating plate 7. When the second clamping plate 5 moves, it will drive the limiting rod 10 and the limiting plate 11 to move together. By setting the limiting plate 11, the second clamping plate 5 can be prevented from moving excessively to one side, causing the second clamping plate 5 to slide out from the inner wall of the first clamping plate 4, so that one side of the arc of the second clamping plate 5 is pushed out of the inner wall of the first clamping plate 4. Then, the two groups of hydraulic cylinders 3 can be started to push the two groups of first clamping plates 4 and second clamping plates 5 to move toward the center, so that the circular or arc-shaped metal parts can be fixed through one side of the arc of the second clamping plate 5.
[0024] Reference Figure 4-5 The inner wall of the first clamping plate 4 is fixedly connected with a limit block 12, and the limit blocks 12 are provided in four groups and are symmetrically distributed on the inner wall of the first clamping plate 4. A sliding groove 13 is provided at the top of the second clamping plate 5, and the second clamping plate 5 is slidably connected to the limit block 12 through the sliding groove 13.
[0025] By setting four groups of limit blocks 12 on the inner wall of the first clamp plate 4, when the second clamp plate 5 slides on the inner wall of the first clamp plate 4, the second clamp plate 5 can slide on the limit blocks 12 through the sliding groove 13 set on the second clamp plate 5, so that the movement trajectory of the second clamp plate 5 can be limited.
[0026] Reference Figure 4-5 A first protection pad 14 is fixedly connected to one side of the first clamping plate 4 , and the shape of the first protection pad 14 fits the square groove. A second protection pad 15 is fixedly connected to one side of the second clamping plate 5 , and the shape of the second protection pad 15 fits one side of the second clamping plate 5 .
[0027] By arranging the first protection pad 14 on one side of the first clamping plate 4, the square metal part can be protected by the first protection pad 14 when the square metal part is clamped. By arranging the second protection pad 15 on one side of the second clamping plate 5, the arc-shaped or circular metal part can be protected by the second protection pad 15 when the arc-shaped or circular metal part is fixed.
[0028] Reference Figure 1-2A correction plate 16 is fixedly connected to the top of the correction platform 1 . The length of the correction plate 16 is consistent with the length of the correction platform 1 . A scale is arranged on the top of the correction plate 16 .
[0029] By arranging a calibration plate 16 with a scale on the top of the calibration platform 1, when calibrating the metal parts, it is convenient to visually observe the metal parts through the scale on the calibration plate 16, which is beneficial to the calibration of the metal parts.
[0030] Reference Figure 5 A sealing gasket 17 is fixedly connected to the outer wall of the second clamping plate 5 . The sealing gasket 17 is made of rubber. The outer wall of the sealing gasket 17 is in contact with the inner wall of the first clamping plate 4 .
[0031] By providing a rubber sealing gasket 17 on the outer wall of the second clamping plate 5, when the second clamping plate 5 moves on the inner wall of the first clamping plate 4, the sealing gasket 17 can be used to maintain a seal between the first clamping plate 4 and the second clamping plate 5, thereby preventing dust and other impurities from entering the gap between the first clamping plate 4 and the second clamping plate 5.
[0032] Working principle: In order to solve the problem that the correction tool is not convenient for fixing metal parts of different shapes, when it is necessary to fix square metal parts, two groups of hydraulic cylinders 3 can be started to make the two groups of hydraulic cylinders 3 simultaneously push the two groups of first clamping plates 4 to move toward the center of the correction platform 1. When the square grooves at the centers of the two groups of first clamping plates 4 move to the outer wall of the square metal parts, the square metal parts can be clamped and fixed, thereby facilitating the correction of the square metal parts. By arranging a first protective pad 14 on one side of the first clamping plate 4, it is convenient to pass through the first protective pad 14 when clamping the square metal parts. A protective pad 14 protects the square metal part. When the circular or arc-shaped metal part needs to be fixed, the threaded rod 6 can be rotated to rotate on the inner wall of the nut 9 and gradually move toward the inner wall of the first clamping plate 4, so that the second clamping plate 5 can be pushed to one side through the rotating piece 7. When the second clamping plate 5 moves, the limiting rod 10 and the limiting piece 11 will move together. By setting the limiting piece 11, the second clamping plate 5 can be prevented from excessively moving to one side, causing the second clamping plate 5 to slide out from the inner wall of the first clamping plate 4, so that the arc-shaped side of the second clamping plate 5 is pushed out of the inner wall of the first clamping plate 4. Four groups of limit blocks 12 are arranged on the inner wall of a clamping plate 4. When the second clamping plate 5 slides on the inner wall of the first clamping plate 4, the second clamping plate 5 can slide on the limit blocks 12 through the slide grooves 13 arranged on the second clamping plate 5, so that the movement trajectory of the second clamping plate 5 can be limited. Then, the two groups of hydraulic cylinders 3 can be started to push the two groups of first clamping plates 4 and second clamping plates 5 to move toward the center, so that the circular or arc-shaped metal parts can be fixed through one side of the arc of the second clamping plate 5. By arranging a second protective pad 15 on one side of the second clamping plate 5, it is convenient to fix the arc-shaped or circular metal parts through the first protective pad 15. The two protection pads 15 protect the arc-shaped or circular metal parts. By setting a correction plate 16 with a scale on the top of the correction platform 1, it is convenient to visually observe the metal parts through the scale on the correction plate 16 when calibrating the metal parts, which is beneficial to the correction of the metal parts. By setting a sealing pad 17 made of rubber material on the outer wall of the second clamping plate 5, when the second clamping plate 5 moves on the inner wall of the first clamping plate 4, it is convenient to maintain the seal between the first clamping plate 4 and the second clamping plate 5 through the sealing pad 17, so as to prevent dust and other impurities from entering the gap between the first clamping plate 4 and the second clamping plate 5.
[0033] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model should be included in the protection scope of the present utility model.
