[0025] Example

[0026] Depend on Figure 1-4 Provided is a finishing clamping device for ductile iron castings, comprising a base 1;

[0027] A rotating shaft seat 3 is rotatably provided on the base 1 and a positioning seat 4 is rotatably connected to the rotating shaft seat 3;

[0028] The end of the positioning seat 4 is threadedly connected with an adjusting bolt 5;

[0029] The sides of the positioning seat 4 and the positioning platform 2 are penetrated by connecting bolts 6, and tension springs 7 are connected between the two connecting bolts 6 on the same side;

[0030] Two positioning pads 10 are arranged on the upper end surface of the base 1 . There is a gap between the two positioning pads 10 , and two positioning blocks 11 are arranged on the upper end surface of each of the two positioning pads 10 . The four positioning blocks 11 are arranged in a rectangular distribution.

[0031] In this embodiment, in actual use, the ductile iron casting can be initially fixed by the movable limit of the four positioning blocks 11, and it can be suitable for the clamping and positioning of ductile iron castings of different sizes. At the same time, the user can move up by rotating one end of the positioning seat 4, and then control the end of the adjusting bolt 5 to contact the upper end of the ductile iron casting until the end of the adjusting bolt 5 is tightly against the upper end surface of the ductile iron casting, so as to achieve the secondary limit of the ductile iron casting, and finally complete the clamping and installation of the ductile iron casting. Compared with the clamping method in the cited document, through the movable limit of the positioning block 11 and the upper limit of the adjusting bolt 5, the overall structure of the processing clamping device of the present application is simple, and the clamping of small-sized workpieces is more stable, and the overall practicality is strong.

[0032] Specifically, refer to Figure 1-3 The positioning block 11 is arranged in an L shape, and the four positioning blocks 11 are distributed in a rectangular shape and arranged opposite to each other. Two sets of lead screw guide rails 12 are arranged on the lower end surface of one of the positioning pads 10 .

[0033] In this embodiment, in actual use, the provided lead screw slide 12 can be used to linearly adjust the position of one of the positioning pads 10, and the user can use the lead screw slide 12 to adjust the distance between the two positioning pads 10 according to the length of the ductile iron piece; when the distance between the two positioning pads 10 is adjusted, the user places the ductile iron piece to be clamped between the four positioning blocks 11. At this time, the preliminary limiting of the ductile iron piece can be achieved through the limiting between the four positioning blocks 11. At the same time, by adjusting the distance between the positioning pads 10, the clamping and positioning of ductile iron pieces of different sizes can also be achieved. The overall structure is simple and easy to use.

[0034] Specifically, refer to Figure 1-3 A limiting block 8 is protruding from the side of the positioning seat 4, and the limiting block 8 is arranged in a rectangular shape.

[0035] In this embodiment, the limit block 8 is used to limit the positioning seat 4. When the limit block 8 is restricted, the positioning seat 4 can be positioned on the positioning platform 2 to avoid autonomous movement.

[0036] Specifically, refer to Figure 1-4 A rotating shaft 91 is rotatably provided on the side of the positioning platform 2 , and a limiting plate 9 is rotatably provided outside the rotating shaft 91 . A triangular notch is formed at the end of the limiting plate 9 , and the triangular notch is engaged with the limiting block 8 .

[0037] In this embodiment, in actual use, the set rotating shaft 91 can be used to limit the limit plate 9, and at the same time cooperate with the limit plate 9 to rotate. When the limit plate 9 rotates and disengages from the limit of the limit block 8, the limit block 8 set at this time can drive the positioning seat 4 to rotate; when the user rotates one end of the positioning seat 4 to move upward, and then controls the end of the adjusting bolt 5 to contact the upper end of the ductile iron part, and rotates the adjusting bolt 5 until the end of the adjusting bolt 5 is tightly against the upper end surface of the ductile iron part. At this time, the adjusting bolt 5 can be used to complete the upper limit of the ductile iron part, and cooperate with the positioning block 11 to further complete the clamping and limiting of the ductile iron part.

[0038] Specifically, refer to Figure 1-4 The lead screw guide rail 12 includes a guide rail seat 121 arranged on the upper end surface of the base 1, a lead screw 122 is rotatably arranged inside the guide rail seat 121, a slider seat 123 is slidably engaged with the outside of the lead screw 122, and the slider seat 123 is connected to one of the positioning pads 10.

[0039] In this embodiment, through the installation between the slider seat 123 and the positioning pad 10, when the screw rod 122 rotates, it is limited by the bottom of the slide rail seat 121. At this time, the slider seat 123 engaged with the outside of the screw rod 122 can move in a straight line along the travel range of the screw rod 122, thereby driving the installed positioning pad 10 to move synchronously until the distance between the two positioning pads 10 is adjusted.

[0040] Specifically, refer to Figure 4 Two side limit rods 124 are also provided on the slide rail seat 121. The two side limit rods 124 are respectively arranged on one side of the slider seat 123 and penetrate the slider seat 123. One end of the screw rod 122 penetrates the slide rail seat 121 and is connected to the shaft handle 125.

[0041] In this embodiment, the rotating shaft handle 125 can be used to manually drive the screw rod 122 to rotate, thereby realizing the position adjustment of the slider seat 123. The side limit rod 124 can cooperate with the slide rail seat 121 to limit the bottom of the slider seat 123, thereby realizing the linear movement of the slider seat 123. In the preferred design, the rotating shaft handle 125 can also be replaced by a motor drive to realize automatic spacing adjustment.

[0042] The utility model is a finishing clamping device for ductile iron castings:

[0043] Step 1: When the user needs to position the ductile iron casting, the distance between the two positioning pads 10 is adjusted according to the length of the ductile iron casting; by rotating the shaft handle 125, the screw rod 122 is rotated along with the shaft handle 125, and at this time, the slider seat 123 engaged on the screw rod 122 is laterally limited by the two side limit rods 124, so that the slider seat 123 engaged on the screw rod 122 can move linearly along the stroke range of the screw rod 122, and the position of one of the positioning pads 10 can be adjusted by rotating the two sets of shaft handles 125, thereby completing the adjustment of the distance between the two sets of positioning pads 10;

[0044] Step 2: After the spacing between the two positioning pads 10 is adjusted, the user places the ductile iron part to be clamped between the four positioning blocks 11. At this time, the ductile iron part is initially limited by the limiting between the four positioning blocks 11. Then the user rotates the limiting plate 9, and through the rotation of the rotating shaft 91, the limiting plate 9 is separated from the limiting of the limiting block 8. At this time, the positioning seat 4 set can be rotated on the positioning platform 2 at one end. The user moves one end of the rotating positioning seat 4 upward, and then controls the end of the adjusting bolt 5 to contact the upper end of the ductile iron part, and then rotates the adjusting bolt 5 until the end of the adjusting bolt 5 is tightly against the upper end surface of the ductile iron part, so as to realize the second limiting and tight contact of the ductile iron part, and finally complete the clamping and installation of the ductile iron part.
