[0001] The utility model relates to the field of mechanical processing tools, in particular to a processing device for special-shaped workpieces. Background Art
[0002] As we all know, jigs and tooling are widely used in the field of mechanical processing technology and manufacturing. The use of jigs and tooling in the processing of disassembled heads will achieve twice the result with half the effort. It not only saves the time for clamping and alignment, but also provides firm and reliable positioning accuracy and reduces processing costs. However, this type of disassembled head is difficult to process without tooling clamping. The pressure plate and screw rod do not have a good fulcrum, which makes it difficult to press and press firmly. In addition, it is difficult to process the surface, drill holes and make pin holes of the large and small flanges of the head in one clamping, which is time-consuming and laborious. When processing in batches, it is even more difficult to ensure the accuracy of all disassembled heads, resulting in the inability to assemble into a complete head in the later stage, resulting in waste and increased costs. The disassembled head requires the same high accuracy for each split body, and ordinary processing methods cannot guarantee the accuracy requirements at all. Summary of the invention

DETAILED DESCRIPTION
[0011] In the figure, the utility model is provided with a tire plate 1, which is placed horizontally, and two side upright plates 2 are perpendicular to the tire plate 1 and aligned with the two sides of the tire plate 1. The side hexagonal screw 4 is vertically screwed on the side upright plate 2 to adjust the left and right positions of the split head. The side hexagonal screw 4 is screwed with a side locking nut 3 to lock and fix the side hexagonal screw 4. The tire fixture fixing plate 5 is installed at an angle of 25° with the tire plate 1 on the top of the two side upright plates 2 to lock the inner surface of the head to provide support. Four inner hexagonal screws 6 fasten the tire fixture fixing plate 5 and the top of the side upright plate 2 together. Four upper hexagonal screws 8 are vertically screwed on the tire fixture fixing plate 5 to support the inner surface of the head. The upper hexagonal screw 8 is screwed with an upper locking nut 9 to lock the upper hexagonal screw 8 to prevent the placed head from loosening. Two positioning pins 10 are installed at the lower part of the top of the side vertical plate 2 to position the tire fixing plate 5 to prevent it from sliding down. The positioning pin 10 is at an angle of 65° with the horizontal plane of the tire plate 1. The support screw rod 14 is vertically screwed on the tire plate 1. The support screw rod 14 is screwed with a nut 15 to lock the support screw rod 14. A pressure plate 13 is fixed to the top of the support screw rod 14. A gasket 12 is mounted on the hexagonal screw 11. The hexagonal screw 11 is screwed into the screw hole of the pressure plate 13. The hexagonal screw The lower end of 11 is vertically screwed on the tire plate 1, the hexagonal screw 11, the gasket 12, the pressure plate 13, the support screw rod 14, and the nut 15 are the pressure plate assembly for pressing the small flange of the head. The tire plate 1 on the inner side of the pressure plate assembly is installed with a front jack through a front jack fixing seat 17, and the front jack fixing seat 17 plays a supporting role. The front jack screw 18 is screwed with a front jack locking nut 16, and the front jack locking nut 16 is used to lock the front jack screw 18 to prevent loosening. The front jack screw 18 pushes the small flange of the head to adjust the horizontal alignment and support of the head. The tire plate 1 below the tire fixing plate 5 is fixed by the rear jack Four rear jacks are installed on the fixed seat 19, and the rear jack fixed seat 19 plays a supporting role. The rear jack locking nut 20 is screwed on the rear jack screw 21, and the rear jack locking nut 20 is used to lock the rear jack screw 21 to prevent loosening. The rear jack screw 21 plays an adjusting and supporting role. The top ends of the four rear jack screws 21 are respectively provided with a first arc surface reference block 22, a second arc surface reference block 23, a third arc surface reference block 24, and a fourth arc surface reference block 25. The first arc surface reference block 22, the second arc surface reference block 23, the third arc surface reference block 24, and the fourth arc surface reference block 25 are in contact with the outer surface of the head to support the head.
[0012] When in use, first install the tire plate 1 horizontally on the workbench of the machining center, align the tire plate 1 and press it on the workbench so that the tire plate 1 moves parallel to the X-axis and Y-axis of the machine tool and perpendicular to the Z-axis. Lift the workpiece 7 onto the first arc surface reference block 22, the second arc surface reference block 23, the third arc surface reference block 24, and the fourth arc surface reference block 25, so that the first arc surface reference block 22, the second arc surface reference block 23, the third arc surface reference block 24, and the fourth arc surface reference block 25 are in contact with the outer arc surface of the head. At this time, adjust the front jack fixing seat number 17 and the front jack screw 18 under the small flange of the head so that the jack is in contact with the small flange of the head. Install the tire fixture fixing plate 5 on the two side vertical plates 2 and position it with two positioning pins 10, then use four hexagonal screws 6 to press the tire fixture fixing plate 5, and then install the four upper hexagonal screws 8 and the four upper locking nuts 9 so that the ends of the screws are close to the inner wall of the head. Use the dial indicator and machine tool action to align the end cap. First, adjust the side hexagonal screws 4 on both sides to push the side of the end cap, so that the extreme positions of the two ends of the large flange on the end cap are equal, that is, the left and rear are aligned, and use the two side locking nuts 3 to lock the side hexagonal screws 4 on both sides; then adjust the front jack screw 18 to push the bottom of the small flange of the end cap, use the dial indicator to check the leveling of the top surface of the large flange of the end cap, and tighten the jack with the front jack locking nut 16, and then make the first arc surface reference block 22, the second arc surface reference block 23, the third arc surface reference block 24, and the fourth arc surface reference block 25 completely fit the outer surface of the end cap, and tighten them with four rear jack locking nuts 20 to prevent loosening caused by vibration during processing. Use the dial indicator to check whether the upper plane of the small flange of the end cap is flat, and finally use the four upper hexagonal screws 8 to force the inner surface of the end cap and tighten them with the upper locking nuts 9. The pressure plate assembly can press the small flange of the head to process the large flange plane, inner circle, drill hole and pin hole of the head. When processing the small flange of the head, the pressure plate assembly should be removed first, and then the small flange plane, inner circle, blank cut, drill hole and pin hole are processed. The parts can be disassembled only after qualified inspection. After the cutter is aligned, batch processing can be carried out.
