[0028] To make the technical problems, technical solutions and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0029] like Figure 1 As shown, this embodiment discloses a forging misalignment detection fixture, including a worktable 1. A rotatable clamping device 2 is provided on the worktable 1. A fixing rod 3 is provided on one side of the clamping device 2. The fixing rod 3 is perpendicular to the worktable 1 and fixedly connected to the worktable 1. A long slot 3-1 is fixedly connected to the fixing rod 3. A sliding plate 3-2 is provided in the long slot 3-1. Both the long slot 3-1 and the plate 3-2 are arranged perpendicular to the worktable 1. A measuring component 4 is fixedly connected to the plate 3-2.

[0030] like Figure 2 As shown, the long slot 3-1 includes two U-shaped slot plates 3-1-1 fixedly connected to the fixing rod 3. The two U-shaped slot plates 3-1-1 are respectively arranged on both sides of the slot plate 3-2. The two vertical long sides of the slot plate 3-2 are tightly attached to the inside of the U-shaped slot plates 3-1-1, and both U-shaped slot plates 3-1-1 are perpendicular to the worktable 1. The slot plate 3-2 can slide up and down against the inner wall of the groove of the two U-shaped slot plates 3-1-1, so that the slot plate 3-2 always remains perpendicular to the worktable 1. This ensures that when measuring different height positions of the same forging, the up and down movement of the measuring component 4 is strictly along the direction perpendicular to the horizontal plane, and no offset error occurs in the height direction. In this embodiment, the two U-shaped slot plates 3-1-1 are connected together to form a whole, and the middle position of the connection part of the two U-shaped slot plates 3-1-1 is fixedly connected to the fixing rod 3.

[0031] One of the U-shaped groove plates 3-1-1 is provided with a threaded first fastening bolt 3-1-2. After passing through the U-shaped groove plate 3-1-1, the first fastening bolt 3-1-2 abuts against the vertical long side of the clamping plate 3-2. When it is necessary to move the measuring component 4 up and down, loosening the first fastening bolt 3-1-2 can slide the clamping plate 3-2 up and down. When it is necessary to fix the height position of the measuring component 4, tightening the first fastening bolt 3-1-2 so that it abuts against the edge of the clamping plate 3-2 can fix the clamping plate 3-2 at that height.

[0032] like Figure 2 As shown, the measuring component 4 includes a scale 4-1 and a T-shaped scale base 4-2. The scale 4-1 is slidably disposed in the T-shaped scale base 4-2 perpendicular to the long groove 3-1, and the T-shaped scale base 4-2 is fixedly connected to the plate 3-2.

[0033] In this embodiment, the T-shaped ruler base 4-2 includes an integrally formed horizontal plate 4-2-1 and a vertical base 4-2-2. A sliding groove 4-2-3 is provided within the horizontal plate 4-2-2, penetrating both the horizontal plate 4-2-1 and the vertical base 4-2-2 and perpendicular to the long slot 3-1. The scale 4-1 is slidably disposed within the sliding groove 4-2-3. The vertical base 4-2-2 is fixedly connected to a vertical slider 4-2-5, which is fixedly connected to the locking plate 3-2. The left and right side walls of the vertical slider 4-2-5 slide in contact with the side plates of the U-shaped groove plate 3-1-1.

[0034] A threaded second fastening bolt 4-2-4 is provided on the transverse plate 4-2-1. The second fastening bolt 4-2-4 passes through the transverse plate 4-2-1 and engages with the scale 4-1. Loosening the second fastening bolt 4-2-4 allows the scale 4-1 to move horizontally within the slide groove 4-2-3, while tightening the second fastening bolt 4-2-4 fixes the scale 4-1 within the slide groove 4-2-3.

[0035] like Figures 3 to 5 As shown, the clamping device 2 includes a three-jaw chuck 2-1, which is mounted on a base 2-2. A connecting rod 2-3 is located at the center of the base 2-2 and extends into the worktable 1. An upper bearing 1-1 and a lower bearing 1-2 are mounted inside the worktable 1. The upper bearing 1-1, lower bearing 1-2, connecting rod 2-3, base 2-2, and three-jaw chuck 2-1 are arranged coaxially, with this axis parallel to the long slot 3-1 and the clamping plate 3-2. The outer rings of the upper bearing 1-1 and lower bearing 1-2 are mounted inside the worktable 1, while the inner rings are fixedly fitted onto the connecting rod 2-3, allowing the connecting rod 2-3 to rotate relative to the worktable 1 under the influence of the upper bearing 1-1 and lower bearing 1-2.

[0036] In this embodiment, the three-jaw chuck 2-1 is a prior art technique. Simply put, it includes a cylindrical chuck base, which is mounted on a base 2-2 and arranged coaxially with the base 2-2. Three sliding jaws arranged in a ring are located at the top of the chuck base. These three sliding jaws are slidably connected to the chuck base and are arranged on the same circle, capable of simultaneously sliding towards or away from the center along a ray extending from the center (this circle is coaxial with the base 2-2). The three sliding jaws can also be fastened to the chuck base with bolts. Placing the forging 5 on the three sliding jaws of the three-jaw chuck 2-1 and sliding the three sliding jaws will hold the forging 5 in place. The centerline of the lower die portion of the forging 5 is collinear with the centerline of the base 2-2, and this centerline is parallel to the long slot 3-1 and the clamping plate 3-2.

[0037] In this embodiment, the connecting rod 2-3 is fixedly connected to the center of the base 2-2 by bolt 2-4.

[0038] The operation process of this utility model is as follows:

[0039] First, place the forging 5 horizontally on the three sliding jaws of the three-jaw chuck 2-1, and then slide the three sliding jaws to clamp it at the bottom of the lower die part of the forging 5. At this time, the center line of the lower die part of the forging 5 is collinear with the center line of the three-jaw chuck 2-1 and the base 2-2.

[0040] Loosen the first fastening bolt 3-1-2 and the second fastening bolt 4-2-4. Adjust the height of the scale 4-1 to align it with the upper die of the forging 5. Tighten the first fastening bolt 3-1-2 to prevent the scale 4-1 from sliding up and down. Slide the scale 4-1 horizontally so that it rests against the side wall of the upper die of the forging 5. Manually rotate the forging 5 and measure at different positions. Read the maximum and minimum values ​​of the scale 4-1 reading. The reading of the scale 4-1 is the distance between the measured position of the upper die of the forging 5 and the axis of the lower die of the forging 5. The average of the difference between the maximum and minimum values ​​of the scale 4-1 reading is the misalignment.

[0041] In addition, there is another working method for cylindrical forgings 5 ​​(i.e., both the lower and upper die parts of forgings 5 ​​are standard cylindrical shapes): Loosen the first fastening bolt 3-1-2, slide the clamping plate 3-2 up and down to the required measurement position height of the lower die part of forgings 5, then tighten the first fastening bolt 3-1-2 to fix the position of the clamping plate 3-2, loosen the second fastening bolt 4-2-4, slide the scale 4-1, place one end of the scale 4-1 against the side wall of the lower die part of forgings 5, keep forgings 5 ​​still, loosen the first fastening bolt 3-1-2, slide the clamping plate 3-2 upward, and keep the scale 4-1 always close to the outer wall of forgings 5, moving upward to the side wall of the upper die part of forgings 5 ​​in the same vertical plane. If forgings 5 ​​are misaligned, the scale 4-1 will move horizontally. At this time, the value of the horizontal movement distance of the scale 4-1 can be read with the help of the T-shaped ruler base 4-2. If the forging 5 does not shift beyond the allowable error range, the horizontal movement distance of the scale 4-1 should be within the allowable error range. Similarly, the forging 5 can be rotated at a certain angle and then fixed in place for retesting.
