Technical Field
[0001] The utility model relates to the technical field of casting, in particular to an alignment tool for scribing on the special-shaped curved surface of medium and large castings. Background Art
[0002] During the inspection of castings, after scribing on the first surface of the casting inspection, scribed lines will be left on the surface of the casting. When the casting is flipped to start scribing on the second surface, it is necessary to align according to the scribed line marks on the first surface, and the height of the thimble is adjusted to ensure that the scribed lines of the casting are perpendicular to the workbench to ensure accurate machining dimensions. In the case of a straight outer wall of a conventional casting, the operation is relatively simple, and a height gauge or the like can be directly used for alignment, and the alignment is relatively easy.
[0003] However, the problem occurs when the outer wall of the casting is a special-shaped surface. When the shape of the casting is complex and the scribed lines are not on the same plane, visual alignment becomes extremely difficult. Due to the lack of a direct reference object, it is easy for the operator to make errors during alignment, resulting in inaccurate alignment of the scribed lines. This will not only cause deviations in the inspection results, but also affect the accuracy of subsequent machining, and further affect the efficiency of the entire production process and the quality of the product. Therefore, a tooling is needed to solve the above problems. Summary of the Utility Model

An adjustment plate is slidably provided on one side of the adjustment block. The support column and the adjustment plate are perpendicular to each other. A line alignment mechanism is detachably provided on one side of the adjustment plate;
[0006] The line alignment mechanism includes a straight surface bracket and an inclined surface bracket. A fixed block is provided on one side of the straight surface bracket. A rotatable movable block is connected by a rotating shaft on one side of the inclined surface bracket.
[0007] Optionally, a chute is opened on one side of the support column. A slider is fixedly connected to the back of the adjustment block. The slider is slidably connected to the inner wall of the chute.

Detailed Description of the Invention
[0021] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0022] Please refer to Figures 1 to 7 , the present utility model provides a technical solution: an alignment tool for scribing the special-shaped curved surface of medium and large castings, including a base 1, a support column 2 and an adjustment mechanism. A support column 2 perpendicular to the base 1 is provided on one side of the base 1. A slidable adjustment block 3 is provided on one side of the support column 2. An adjustment plate 4 is slidably provided on one side of the adjustment block 3. The support column 2 and the adjustment plate 4 are perpendicular to each other. An alignment mechanism is detachably provided on one side of the adjustment plate 4;
[0023] The alignment mechanism includes a straight surface bracket 7 and an inclined surface bracket 8. A fixed block 9 is provided on one side of the straight surface bracket 7. A rotatable movable block 10 is connected to one side of the inclined surface bracket 8 through a rotating shaft.
[0024] The support column 2 is placed on the base 1 and its position can be adjusted to align different positions. The adjustment block 3 can slide on the support column 2, and the adjustment plate 4 can slide on the adjustment block 3. By adjusting the height of the adjustment block 3 and the extension length of the adjustment plate 4, the alignment position can be adjusted. The support column 2 is perpendicular to the operating table. The fixed block 9 on one side of the straight surface bracket 7 is parallel to the support column 2, which is convenient for the fixed block 9 to fit the vertical surface of the casting. The movable block 10 can rotate. By adjusting the angle of the movable block 10, the movable block 10 can be made to fit the inclined surface of the casting, which is convenient for alignment. A sleeve and a top rod are also provided on the base 1. By rotating the top rod, the overall height can be adjusted. When aligning the casting, the heights on both sides of the casting can be adjusted to reduce the alignment difficulty.
[0025] In this embodiment, as a preferred solution, a chute 11 is opened on one side of the support column 2. A slider 12 is fixedly connected to the back of the adjustment block 3. The slider 12 is slidably connected to the inner wall of the chute 11. A first bolt 13 and a second bolt 14 are threadedly connected to one side of the adjustment block 3. One end of the first bolt 13 abuts against the inner wall of the chute 11 to fix the adjustment block 3. An adjustment groove 15 is opened on one side of the adjustment plate 4. The second bolt 14 penetrates into the inner wall of the adjustment groove 15 to fix the adjustment plate 4. The width of one end of the movable block 10 is the same as the width of the inclined surface bracket 8.
[0026] The slider 12 is connected to the chute 11. When the adjusting block 3 is slid, the slider 12 will be driven to slide up and down in the chute 11. When the first bolt 13 is rotated, the first bolt 13 will abut against the bottom of the chute 11, so that the slider 12 is closely attached to the inner wall of the chute 11, thereby fixing the position of the adjusting block 3. One end of the second bolt 14 is threadedly connected to the inner wall of the slider 12. After the second bolt 14 is tightened, the bottom of the second bolt 14 presses on the surface of the adjusting groove 15 to fix the position of the adjusting plate 4.
[0027] In this embodiment, as a preferred solution, a pin hole 16 is provided on one side of the adjusting plate 4. A pin 17 is fixedly connected to one side of both the straight surface bracket 7 and the inclined surface bracket 8. The pin 17 is inserted into the pin hole 16.
[0028] The pin 17 is inserted into the pin hole 16, so as to install the line alignment mechanism on the adjusting plate 4. A notch is provided on one side of the adjusting plate 4, which can reduce the difficulty of disassembly when the line alignment mechanism is disassembled.
[0029] In this embodiment, as a preferred solution, an adjusting bolt 18 is provided on one side of the inclined surface bracket 8, and a friction pad 19 is provided on the surface of the movable block 10. The adjusting bolt 18 abuts against the surface of the friction pad 19.
[0030] The movable block 10 can rotate around one end of the inclined surface bracket 8. When the adjusting bolt 18 is rotated, it will abut against the friction pad 19 on the surface of the movable block 10. After the adjusting bolt 18 abuts against the friction pad 19, the position of the movable block 10 can be fixed to prevent the movable block 10 from rotating.
[0031] In the present utility model, the working steps of the device are as follows:
[0032] 1. Refer to Figure 7 , place the casting on the workbench, use a set of ejector pins at the bottom to adjust the balance on one side, adjust a single ejector pin, and adjust the engraved line left on the first surface of the casting to a state nearly perpendicular to the workbench;
[0033] 2. Adjust the height of the adjusting plate 4 by sliding the adjusting block 3, so as to adjust the height of the straight surface bracket 7 or the inclined surface bracket 8 at one end, so that it aligns with the position to be line-aligned. By sliding the adjusting plate 4, the two can be attached to the surface of the casting, so that the line alignment mechanism can be close to the casting and be more accurate during line alignment;
[0034] 3. Adjust the third ejector pin. When the engraved line on the surface of the casting fits with one end of the line alignment mechanism, the casting is in a vertical state.
