Description

Technical Field

[0001] The present invention belongs to the technical field of scroll processing, and in particular relates to a scroll processing method. Background Art

[0002] like Figure 1 and Figure 2 The figure shows a scroll blank, which includes a scroll plate 1 with a circular plate-like structure. The middle part of the surface of one side of the scroll plate protrudes outward to form a boss with a cylindrical structure. A circular bearing hole 2 is provided in the middle position of the end face of the boss. Six annular holes 3 are evenly provided along the circumferential direction of the boss on the surface of one side of the scroll plate, and a special-shaped hole 4 is provided between any three adjacent groups of annular holes. In addition, the outer circumferential surface of the scroll plate partially protrudes outward to form three evenly distributed process overlap blocks 5, and a positioning hole 6 is provided on one of the process overlap blocks. A vortex plate 7 with an overall spiral belt structure is provided on the surface of the other side of the scroll plate, and a sealing groove with an overall spiral structure is provided along its spiral direction on the outer end face of the scroll plate.

[0003] In the prior art, when processing the above-mentioned scroll, the following steps are usually included: 1. Rough turning the scroll end face and outer circle using a CNC turning center; 2. Rough milling the scroll profile and outer circle arc using a machining center; 3. Turning the bearing hole and annular hole using a CNC turning center; 4. Fine milling the scroll profile, sealing groove and chamfer using a machining center; 5. Turning the process overlap block and chamfer using a CNC turning center; and finally, inspecting and packaging for storage. The existing processing technology has the following disadvantages: 1. It needs to be clamped on different processing equipment, with many clamping times, wasting processing time, resulting in low processing efficiency, and multiple clamping processes, resulting in reduced processing accuracy; 2. It is necessary to design process overlap blocks, which requires more materials when manufacturing the blank, resulting in material waste, and a larger amount of processing is required in subsequent processing.

[0004] Therefore, how to provide a scroll processing method that can improve processing efficiency, reduce processing costs, and better ensure precision has become a technical problem to be solved by those skilled in the art. Summary of the Invention

[0005] In view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by the present invention is: how to provide a scroll machining method that can improve machining efficiency, reduce machining costs, and better ensure precision.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0007] A scroll processing method comprises the following steps: a. obtaining a scroll blank, wherein the scroll blank obtained in step a comprises a scroll plate of a circular plate-like structure, wherein the middle portion of one surface of the scroll plate protrudes outward to form a circular boss, a circular bearing hole is provided in the middle portion of the end face of the boss, six annular holes are provided on the outer side of the boss on the surface of the scroll plate and evenly along its circumferential direction, and a special-shaped hole is provided between any three adjacent pairs of annular holes; and further comprises the following steps: b. completing clamping with one surface of the scroll plate and the outer circumferential surface as a clamping reference, and rough-machining the scroll plate. The outer end face, spiral surface of the scroll plate and the surface of the scroll plate; c. The outer end face of the scroll plate processed in step b and the outer circumferential surface corresponding to the scroll plate are used as the clamping reference to complete the clamping, and the other surface of the scroll plate, the outer circumferential surface of the scroll plate, the bearing hole, the annular hole and the special-shaped hole are processed; d. The outer circumferential surface of the scroll plate and the other surface of the scroll plate processed in step c are used as the clamping reference to complete the clamping, and the outer end face of the scroll plate, the spiral surface of the scroll plate and the surface of the scroll plate are semi-finished and finished, and the processing of the sealing groove is completed; e. Inspection and packaging are carried out for storage.

[0008] In this way, in the above-mentioned scroll processing method, the scroll blank obtained does not require a process overlap block compared to the scroll blank in the existing processing technology, so that when the scroll blank is manufactured, the material demand can be reduced and costs can be saved. It also eliminates the subsequent step of removing the process overlap block, thereby reducing the amount of cutting required and making the design more reasonable. In addition, in the existing processing technology, after obtaining the scroll blank, there are fewer processing steps and only three clampings are required. Compared with the existing process, the number of clampings is reduced, which can save time and improve processing efficiency. Secondly, in this processing technology, the clamping datum for the latter time is obtained from the previous processing, which makes the clamping positioning more accurate and the processing accuracy higher.

[0009] As an optimization, in step a, the scroll blank is obtained by casting.

[0010] In this way, it is more convenient to manufacture the scroll blank and the manufacturing cost is lower.

[0011] As an optimization, in step b, one surface of the scroll plate is used as the positioning surface, and the outer circumferential surface of the scroll plate is used as the clamping surface for clamping.

[0012] In this way, when clamping, the scroll can be clamped more conveniently, and the clamping operation is more convenient. Further, in step b, a vertical three-jaw chuck is used for clamping.

[0013] As an optimization, in step c, the outer end surface of the swirl plate is used as the positioning surface, and the outer circumferential surface corresponding to the swirl plate is used as the clamping surface for clamping.

[0014] In this way, when clamping, the outer end surface of the scroll plate and the outer circumferential surface corresponding to the scroll plate obtained in the previous step are used as the clamping reference, which makes clamping more convenient and can improve the clamping accuracy. Further, in step c, a floating three-jaw chuck is used for clamping.

[0015] As an optimization, in step d, the other surface of the scroll plate is used as the positioning surface, and the outer circumferential surface of the scroll plate is used as the clamping surface for clamping.

[0016] Thus, when clamping, the other surface of the scroll plate and the outer circumferential surface of the scroll plate obtained in the previous step are used as the clamping reference, which makes clamping more convenient and improves the clamping accuracy. Furthermore, in step d, a film chuck is used for clamping.

[0017] As an optimization, steps b, c, and d are all processed using a CNC machining center.

[0018] In this way, processing can be completed on the same equipment, saving equipment and eliminating the need for transporting and transferring workpieces. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] In this way, in the above-mentioned scroll processing method, the scroll blank obtained does not require the process overlap block 5 and the positioning hole 6 compared with the scroll blank in the existing processing technology, so that when the scroll blank is manufactured, the material demand can be reduced and the cost can be saved.

In addition, in the existing processing technology, after the scroll blank is obtained, the processing steps are fewer and only three clampings are required. Compared with the existing process, the number of clampings is reduced, which can save time and improve processing efficiency. Secondly, in this processing technology, the clamping datum of the latter time is obtained by the previous processing, which makes the clamping positioning more accurate and the processing accuracy higher.

Specifically, in step c, a floating three-jaw chuck is used for clamping.

[0032] In the embodiment, in step d, the other surface of the scroll plate is used as a positioning surface, and the outer circumferential surface of the scroll plate is used as a clamping surface for clamping.
