[0017] To more clearly and in detail illustrate the objective technical solution of this utility model, the present utility model will be further described below through relevant embodiments. The following embodiments are merely illustrative of the implementation methods of this utility model and do not limit the scope of protection of this utility model.
[0018] Example 1
[0019] like Figures 1-3 As shown, a correction device for a circular casting includes an upper pressure member 2 and a lower pressure member 1. The upper pressure member 2 and the lower pressure member 1 are joined together to form a circular cavity. Four reset mechanisms 3 are symmetrically arranged on both sides of the cavity on the lower pressure member 1. Each reset mechanism 3 includes a spring sleeve 31 and a reset spring 32. The lower pressure member 1 is provided with four cross-shaped reset cavities 11 to accommodate the reset mechanisms 3. The reset cavities 11 are perpendicular to the upper surface of the lower pressure member 1. The spring sleeve 31 can be placed inside the reset cavity 11. A limiting plate 33 is provided on the outer side of the spring sleeve 31. The limiting plate 33 is engaged in the side cavities of the reset cavity 11, and the thickness of the limiting plate 33 is shorter than the height of the side cavities, so that the spring sleeve 31 can move up and down. The reset spring 32 is located inside the spring sleeve 31 and is in a compressed state. The upper pressure member 2 is provided with four positioning holes corresponding to the spring sleeve 31.
[0020] The circular cavity of the calibration device is made according to the standard dimensions of the circular casting. The casting to be calibrated is placed in the cavity of the lower pressure member 1, aligned with the spring sleeve 31 and the positioning hole, and the upper pressure member 2 is closed. The calibration device is placed on the machine tool, and pressure is applied to the upper pressure member 2 by a hydraulic press. The return spring 32 is compressed and contracts, and the spring sleeve 31 is compressed and returns to the positioning cavity 11. The casting is squeezed into a perfect circle that matches the circular cavity. The casting is removed, and under the reaction force of the return spring 32, the spring sleeve 31 springs upward, and the device is reset.
[0021] Example 2
[0022] like Figure 4 As shown, the reset mechanism 3 also includes a limiting post 34 and a limiting plug 35. The reset spring 32 is sleeved on the limiting post 34. The outer diameter of the limiting plug 35 is adapted to the inner diameter of the spring sleeve 31. The limiting plug 35 is provided with a limiting channel 351. The limiting post 34 is inserted into the limiting channel 351. The reset spring 32 is located below the limiting plug 35.
[0023] The return spring 32 moves steadily up and down along the limiting post 34, which is inserted into the limiting channel 351. The return spring 32 moves up and down against the limiting plug 35. The outer diameter of the limiting plug 35 is adapted to the inner diameter of the spring sleeve 31, thus restricting the up and down movement of the limiting plug 35 and further stabilizing the linear up and down movement of the return spring 32.
[0024] The limiting plug 35 is a frustum shape, smaller at the top and larger at the bottom. This reduces the contact area between the limiting plug 35 and the spring sleeve 31, resulting in less friction and less wear.
[0025] The circular cavity extends through both sides.
[0026] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
