INSTRUCTIONS OF THE INVENTION: TECHNICAL FIELD OF THE INVENTION The present invention relates to the field of manufacturing a finger-type by means of horizontal and vertical directional macro/rolling, in particular, and i. The process of making the scrolls firmly hold the solids and thus processing the scrolls more accurately. [Prior Art] Volume, Figure 2: The scroll processing method of the machine is to take the two sides of the vortex 1 of the wheel type: 'Gu Juan 8 has - disc 8 1, the disc 8 and one The scroll piece 83 is further connected to the reference surface 811, and the adjacent surface of the disk 8 1 and the seat body 8 2 are processed, and then the scroll piece 83 is exposed by the surface of the disk 811. The processing of the scroll piece is performed by adding an implement. However, limited by the thickness of the disc 8i, the contact area of the reference surface 811 and the clip 9 is small, which may cause the w forest to turn over, and the disc 8 is deflected during the processing of the scroll 8 . The phenomenon, which in turn causes the deflection of the wrap 8 3 after processing, it is necessary to know that the accuracy of the flat (4) and the perpendicularity of the wrap 8 is controlled at 8 unmj^, as long as a skew occurs, processing After the vortex sheet 8 3 is easily generated to be larger than the skew in σ 差 差, and becomes a defective product, it is necessary to improve it. Further, if there are pores in the spiral formed by casting, it is easy to produce a defective product after the addition of =, and therefore, the casting of the scroll has been generally used for pressure casting. Spoon method, but the inventor found that the current pressure prayer method still exists for the existence of stomata, so there is still a need for improvement. 1250251 SUMMARY OF THE INVENTION The main object of the present invention is to solve the above problems and provide a scroll processing process for a compressor, which is formed by processing a vertical reference surface and a horizontal reference surface on a disk of a scroll formed by a die casting. Then, the seat body is clamped by the tool and pulled down, so that the horizontal reference surface of the scroll is closely attached to the fixture platform, and is clamped to the vertical reference surface by the clamp, so that the scroll is firmly clamped and fixed, and finally processed. The machine processes the scroll to ensure that the processing surfaces of the scroll can be parallel to the vertical reference plane or the horizontal reference plane, thereby improving the precision of the machining. A second object of the present invention is that the scroll sheet is cast in a secondary pressurization process during casting to increase the strength of the scroll. For the purpose of the foregoing, the scroll processing process of the compressor of the present invention comprises the following steps: Casting: casting a wrap by die casting, the wrap having a disc having a body on each side of the disc And a scroll piece; the machining reference surface: a vertical reference surface and a horizontal reference surface are respectively formed on the outer edge surface of the disk and adjacent to the one surface of the base body, and the outer edge surface of the base body is processed at the same time; And positioning: clamping the seat with a tool and pulling it down, so that the horizontal reference surface of the scroll is positioned on the fixture platform, and the scroll piece protrudes from the fixture; clamping: clamping with a clamp Holding the vertical reference surface, the scroll is firmly clamped and fixed; 1250251 has a high strength in degrees. The scroll casting has a disc 1 having a body 1 1 and a scroll 1 2 on both sides. ^ Machining datum surface: a vertical reference surface 13 and a horizontal reference surface 14 are respectively formed on the outer edge surface of the disc 1 and a surface adjacent to the base body 11, and the outer surface of the base body 1 1 is processed at the same time. In the embodiment, the movable scroll is taken as an example, and a positioning hole 16 is drilled at a position where the horizontal reference surface 丄 4 of the disk 1 corresponds to the starting point of the scroll piece 2 . Pull down the workpiece and positioning: Hold the seat χ 以 with the tool 18, as shown in Figure 2A, and pull it down so that the horizontal reference surface 该4 of the vortex is attached to the fixture platform 2 =, and The fixture platform 2 is provided with a position member 2丄, so that when the scroll is pulled down, the positioning hole 16 can be placed on the positioning member 2丄, and the initial position of the scroll piece can be positioned and vortexed. The sheet i 2 protrudes from the jig platform 2. σ Clamp: Hold the clamp 3 on the vertical datum surface 1 q You sit and the soil is 0.77丄d, so that the wrap is firmly clamped and fixed by the stable wrap, then the machine can be vortexed by 1 J Winding 1 === Each of the working faces of the scroll 12 can be parallel to the vertical or horizontal reference plane. When the thirsty roll is fixed, the work is carried out and 1 P 10/, 8 is clamped and the seat 1250251 1 is pulled down, so that the horizontal reference surface 14 of the wrap is adhered to the jig platform 2, resulting in a vertical positioning force; and when the clamp 3 is clamped to the vertical reference surface 13 , a lateral positioning force is generated. In other words, the present invention applies a bidirectional positioning force to the scroll, so that it can be processed subsequently. In the process, the scroll is surely positioned without the problem that the scroll is deflected due to the processing force, and the processing faces of the scroll 12 can be parallel to the vertical reference plane or the horizontal reference plane, and can conform to High precision requirements. Further, in the casting molding step, the scroll of the present invention is pressurized twice by the shot oil cylinder in the case where the molten aluminum alloy starts to be cooled and shrunk, and 3 to 5 seconds before it is completely crystallized. Therefore, the scroll casting obtained after the secondary pressurization can achieve high strength conditions such as high density, high toughness and high tensile strength. In addition to the above method, the tool body 1 is used to pull the seat body 1 1 to pull it down. The following method can also be adopted: After the step of processing the reference surface, the following steps are performed: Screw hole processing: in the seat The body 1 1 is partially machined with at least one screw hole 15 parallel to the vertical reference plane, as shown in FIG. 2B. The lock lever is: a pull rod 17 is locked in the screw hole 15 to extend a portion of the pull rod 17 out of the seat body 11. Thereby, the pull-down workpiece and the positioning step can be clamped by the tool (not shown) to perform the positioning work, so that the same work can be achieved. 1250251 In the foregoing embodiment, the movable scroll is taken as an example to illustrate the process. In the process of the fixed scroll, there will be a difference in the structure of the fixed scroll (as shown in FIG. 4), because several parts are processed on the seat 4 1 of the fixed scroll 4 in the screw hole processing step. The screw hole 4 5 of the fixed scroll is fixed, so that in the step of locking the rod, one of the screw holes is locked. In summary, the present invention holds the horizontal reference surface of the scroll against the fixture platform by clamping and pulling down the rod with the tool, and clamps the vertical reference surface with the clamp so that the scroll is firmly clamped and fixed. The crucible is formed to form a bidirectional positioning force on the scroll to ensure that each of the processing faces of the scroll can be parallel to the vertical reference plane or the horizontal reference plane, thereby achieving the effect of improving the precision of the machining. Further, the scroll piece is cast in a secondary pressurization process during the casting process to achieve the effect of increasing the strength of the scroll. The above description of the embodiments is intended to be illustrative of the invention, and is not intended to limit the scope of the invention. From the above detailed description, it will be apparent to those skilled in the art that the present invention can achieve the above-mentioned objects, and is in accordance with the provisions of the Patent Law.
