Description

Technical Field

[0001] The utility model relates to the technical field of scroll disk processing, in particular to a scroll disk clamping assembly and a scroll disk processing device. Background Art

[0002] The scroll disk is the main component of the scroll refrigeration compressor that compresses the cooling medium. This type of compressor has good refrigeration efficiency and is widely used in traditional air conditioners and new energy vehicle air conditioners. There are two conventional manufacturing processes for scroll disks: the first is to form a part blank by casting, and then use CNC equipment to clamp and fine-process it in two times. The second is to use a round blank and clamp it directly on the CNC equipment in two times to directly fine-process it into shape. Regardless of which method is used, it needs to be clamped twice on the CNC equipment. The intermediate body formed after the initial structure is processed by the first CNC is as follows: Figure 1 As shown, the intermediate formed after the second CNC processing is as follows Figure 2 As shown, the final scroll disk has the following features: Figure 3 shown.

[0003] During the first CNC machining, the bottom of the initial structure needs to be clamped to perform CNC machining on the top of the initial structure to form a Figure 1 During the second CNC machining, the top of the intermediate body needs to be clamped to perform CNC machining on the bottom of the intermediate body to form the following Figure 2 The intermediate body shown. Since the positions of the two clampings are different and the structure of the intermediate body after the first CNC processing has changed compared to the initial structure, it is difficult to achieve accurate positioning of the two processings during the second CNC clamping process through the straight body feature of the part, especially when clamping the intermediate body, the clamping component is difficult to adapt to the intermediate body after the first CNC processing, resulting in low clamping accuracy of the intermediate body, making the intermediate body easily offset during the second CNC processing, affecting the CNC processing effect. Utility Model Content

[0004] In order to overcome the problems existing in the related technology, one of the purposes of the utility model is to provide a vortex plate clamping assembly, which uses a limiting protrusion to limit and fix the notch, and uses a fastener to fix the limiting through hole. The structure is simple and can achieve stable clamping of the intermediate structure.

[0005] A scroll plate clamping assembly is used to clamp the top of an intermediate body, wherein the intermediate body comprises an outer ring and a scroll cavity located inside the outer ring, and a notch is provided at the top of the outer ring.

[0006] The scroll plate clamping assembly is provided with a placement groove adapted to the outer ring, the placement groove is provided with a limiting protrusion adapted to the notch, the side wall of the outer ring is provided with a limiting through hole, and the side wall of the placement groove is provided with a fastener adapted to the limiting through hole.

[0007] The limiting protrusion in the placement groove of the utility model can be engaged with the notch in the intermediate body to achieve limiting fixation of the notch, and avoid the intermediate body from rotating and other positional deviations inside the placement groove. After the notch is limited by the limiting protrusion, the limiting through hole in the outer ring side wall is fixed by the fastener in the side wall of the placement groove. The utility model uses the limiting protrusion to limit and fix the notch, and at the same time uses the fastener to fix the limiting through hole. The structure is simple, and can achieve stable clamping of the intermediate body structure. At the same time, the outer side of the bottom of the outer ring can be exposed, which is convenient for the second CNC processing of the intermediate body to form a heterogeneous boss on the outer side of the bottom of the outer ring, thereby improving the clamping efficiency and processing efficiency of the swirl disk.

[0008] Furthermore, the vortex chamber includes vortex protrusions spirally arranged in sequence from the center of the outer ring to the outside, the bottom of the vortex protrusion is located at the bottom of the outer ring, and the height of the vortex protrusion is less than the height of the outer ring.

[0009] Furthermore, the top of the vortex protrusion is flush with the bottom of the notch, and the bottom of the notch refers to a side of the notch close to the bottom of the outer ring.

[0010] The height of the vortex protrusion is smaller than the height of the outer ring, which can facilitate the installation of the vortex disk. Correspondingly, when setting the clamping assembly, it is necessary to set it according to the height and structure of the vortex protrusion to ensure that the clamping assembly can fit with the top of the intermediate body and achieve stable clamping of the bottom of the intermediate body. Here, the top of the intermediate body refers to the top of the outer ring.

[0011] Furthermore, the placement groove includes an annular groove and a limiting boss located inside the annular groove, and the annular groove is provided with a limiting boss that is adapted to the notch in the intermediate body, and the top of the limiting boss is flush with the limiting boss; when the intermediate body is placed in the placement groove, the outer ring is located in the annular groove, the vortex boss abuts against the limiting boss, and the notch abuts against the limiting boss.

[0012] By setting the annular groove, limiting protrusion and limiting boss, it can be ensured that when the top of the intermediate body is placed downward in the placement groove, the outer ring is adapted to snap into the annular groove, the notch is adapted to snap into the limiting protrusion, and the vortex protrusion is adapted to snap into the limiting boss, so that the clamping assembly and the top of the intermediate body can be snapped in. On the basis of the above snap connection, the fasteners in the clamping assembly fasten the limiting through holes in the side walls of the outer ring, so that the clamping assembly can be precisely snapped and stably fixed to the intermediate body. Due to the precise snap connection of the annular groove, limiting protrusion and limiting boss to various parts of the intermediate body, it is ensured that the clamping assembly will not undergo relative displacement during the process of clamping the intermediate body, ensuring the stability of the clamping process.

[0013] Furthermore, positioning grooves are provided on both sides of the limiting protrusion in the circumferential direction, and the positioning grooves are located on the side of the annular groove away from the center of the circle.

[0014] The utility model sets positioning grooves on both sides of the limiting protrusion, which can ensure that when the outer ring enters the annular groove, the outer ring side wall at the corresponding position of the positioning groove is clamped, and the intermediate is placed in the placement groove under the clamping action. Similarly, after the intermediate completes the second CNC processing, by clamping the outer side of the outer ring at the positioning groove, that is, using the outer side of the outer ring at the positioning groove as the force point, the intermediate can be quickly taken out of the clamping assembly. Therefore, the positioning groove located away from the center of the annular groove can realize convenient assembly and separation between the intermediate and the clamping assembly, thereby improving the clamping and disassembly efficiency of the intermediate.

[0015] Furthermore, positioning grooves are provided on both sides of the limiting protrusion in the circumferential direction, and the positioning grooves are located on one side of the annular groove close to the center of the circle.

[0016] Furthermore, a positioning protrusion is provided on the outer side wall of the outer ring, and the distance between the top of the positioning protrusion and the top of the outer ring is greater than the distance between the bottom of the notch and the top of the outer ring; the depth of the placement groove is equal to the minimum distance between the top of the positioning protrusion and the top of the outer ring.

[0017] The depth of the placement groove is matched with the height of the outer ring above the positioning protrusion, so that the outer ring can be just clamped in the placement groove and the positioning protrusion is exposed on the outside of the placement groove without interfering with the placement groove and affecting the positioning and clamping of the outer ring by the clamping assembly.

[0018] Furthermore, the fastener includes a fastening through hole and a fastening screw, the fastening through hole passes through the side wall of the clamping assembly, and the fastening screw passes through the fastening through hole and the limiting through hole.

[0019] When the intermediate body is placed in the placement groove, since the fastening through hole and the limiting through hole correspond one to one, the positioning of the notch and the limiting protrusion can ensure that the limiting through hole and the fastening through hole correspond one to one. At this time, the fastening screws are passed through the fastening through hole and the limiting through hole in sequence, and fixed with the fastening nut, so as to achieve the fixation of the intermediate body and the clamping assembly. The fastening through hole and the fastening screw have a simple structure and are easy to install, and can achieve rapid alignment of the fastening through hole and the limiting through hole through the mutual cooperation between the limiting protrusion and the notch.

[0020] Furthermore, the limiting through holes and the notches are staggered, and there are a plurality of limiting through holes, which are evenly distributed along the circumferential direction of the outer ring, and the fastening through holes and the limiting through holes in the clamping assembly are arranged in a one-to-one correspondence.

[0021] The limiting through hole needs to cooperate with the fastening through hole and the fastening screw to fix the intermediate body and the clamping assembly. If the limiting through hole coincides with the notch, the position of the fastening screw is uncertain. Therefore, the limiting through hole and the notch in the intermediate body need to be staggered.

[0022] The second purpose of the present utility model is to provide a scroll processing device, including a scroll clamping assembly as described above.

[0023] The beneficial effects of the utility model are:

[0024] The clamping assembly in the utility model is used to clamp the intermediate after the first CNC processing, so as to realize the second CNC processing of the intermediate to form the final scroll disk; the intermediate includes an outer ring and a vortex cavity located inside the outer ring, the top of the outer ring is provided with a notch, the bottom of the outer ring is used for the second CNC processing, the outer ring is a cylindrical groove structure, the side of the groove opening is the top of the outer ring, the inside of the groove is the vortex cavity, and the outer bottom of the groove is used for the second CNC processing to form a heterogeneous boss. With respect to the intermediate structure, a placement groove adapted to the outer ring is provided in the scroll disk clamping assembly of the utility model. When the intermediate is placed in the placement groove, the top of the outer ring is placed downward in the placement groove. Correspondingly, the limiting protrusion in the placement groove of the utility model can engage with the notch in the intermediate to realize the limiting fixation of the notch and avoid the intermediate from rotating inside the placement groove and other positional deviations. After the notch is limited by the limiting protrusion, the limiting through hole in the outer ring side wall is fixed by placing a fastener in the groove side wall. The utility model uses the limiting protrusion to limit and fix the notch, and uses the fastener to fix the limiting through hole. The structure is simple and can achieve stable clamping of the intermediate structure. At the same time, the outer side of the outer ring bottom can be exposed, which is convenient for the second CNC processing of the intermediate to form a heterogeneous boss on the outer side of the outer ring bottom, thereby improving the clamping efficiency and processing efficiency of the scroll disk.

[0025] The utility model also provides a scroll disk processing device, including the scroll disk clamping assembly as described above, which is used to clamp the intermediate body after the first CNC processing, and at the same time, the notch is limited and fixed by a limiting protrusion, and the limiting through hole is fixed by a fastener, so that the outer side of the bottom of the outer ring is exposed, which is convenient for the second CNC processing of the intermediate body to form an anisotropic boss on the outer side of the bottom of the outer ring, thereby improving the accuracy of CNC processing of the scroll disk.

[0039] Example 1

[0040] like Figure 1-Figure 3 As shown, the scroll disk clamping assembly provided by the utility model is used to clamp an intermediate body for a second CNC processing; the intermediate body is a structure after the first CNC processing, and the intermediate body includes an outer ring 11 and a vortex chamber located inside the outer ring 11, the top of the outer ring 11 is provided with a notch 13, and the bottom of the outer ring 11 is used for the second CNC processing. The utility model defines the structure that has not been CNC processed as the initial structure, defines the structure after the first CNC processing as the intermediate body, and defines the structure after the second CNC processing as the final scroll disk. During the first CNC processing of the initial structure, the clamping assembly 21 is also required for clamping. The clamping assembly 21 corresponding to the first CNC processing is not described in detail in the utility model. The intermediate body formed after the initial structure is processed by the first CNC is as shown in FIG. Figure 1 As shown, the intermediate formed after the second CNC processing is as follows Figure 2 As shown, the final scroll disk has the following features: Figure 3 shown.

[0041] During the first CNC machining, the bottom of the initial structure needs to be clamped to perform CNC machining on the top of the initial structure to form a Figure 1 During the second CNC machining, the top of the intermediate body needs to be clamped to perform CNC machining on the bottom of the intermediate body to form the following Figure 2The intermediate body shown. Since the positions of the two clampings are different and the structure of the intermediate body after the first CNC processing has also changed compared to the initial structure, it is difficult to achieve accurate positioning of the two processings during the second CNC clamping process through the straight body feature of the part. Therefore, the utility model needs to design a clamping assembly 21 that is compatible with the intermediate body to be clamped.

[0042] like Figure 4-Figure 8 As shown, the vortex disk clamping assembly provided by the utility model is provided with a placement groove adapted to the outer ring 11, the placement groove is provided with a limiting protrusion 23 adapted to the notch 13, the side wall of the outer ring 11 is provided with a limiting through hole 15, and the side wall of the placement groove is provided with a fastener adapted to the limiting through hole 15.

[0043] Specifically, the intermediate body includes an outer ring 11 and a vortex cavity located inside the outer ring 11. A notch 13 is provided at the top of the outer ring 11. The bottom of the outer ring 11 is used for the second CNC processing. The outer ring 11 is a cylindrical groove structure. One side of the groove opening is the top of the outer ring 11. The inside of the groove is the vortex cavity. The outer bottom of the groove is used for the second CNC processing to form an anisotropic boss 16.

[0044] Correspondingly, a placement groove adapted to the outer ring 11 is provided in the scroll clamping assembly of the utility model. When the intermediate body is placed in the placement groove, the top of the outer ring 11 is placed downward in the placement groove. Correspondingly, the limiting protrusion 23 in the placement groove of the utility model can be engaged with the notch 13 in the intermediate body to achieve limiting fixation of the notch 13, and avoid the intermediate body from rotating and other positional displacements inside the placement groove. After the notch 13 is limited by the limiting protrusion 23, the limiting through hole 15 in the side wall of the outer ring 11 is fixed by the fastener in the side wall of the placement groove. The utility model uses the limiting protrusion 23 to limit and fix the notch 13, and at the same time uses the fastener to fix the limiting through hole 15. The structure is simple, and can achieve stable clamping of the intermediate body structure. At the same time, the outer side of the bottom of the outer ring 11 can be exposed, which is convenient for the second CNC processing of the intermediate body to form an anisotropic boss 16 on the outer side of the bottom of the outer ring 11, thereby improving the clamping efficiency and processing efficiency of the scroll.

[0045] Example 2

[0046] like Figure 4-Figure 8 As shown, the vortex disk clamping assembly provided by the utility model is provided with a placement groove adapted to the outer ring 11, the placement groove is provided with a limiting protrusion 23 adapted to the notch 13, the side wall of the outer ring 11 is provided with a limiting through hole 15, and the side wall of the placement groove is provided with a fastener adapted to the limiting through hole 15.

[0047] The outer ring 11 of the intermediate body of the utility model is provided with a vortex cavity inside, and the vortex cavity includes vortex protrusions 12 which are arranged spirally from the center to the outside of the outer ring 11. The bottom of the vortex protrusion 12 is located inside the bottom of the outer ring 11, and the height of the vortex protrusion 12 is less than the height of the outer ring 11. The outer ring 11 is a cylindrical groove structure, such as Figure 1 As shown, one end face of the cylindrical groove is open, and the other end face is closed. The utility model defines that one side of the cylindrical groove opening is the top of the outer ring 11, the inside of the groove is the vortex cavity, and the bottom outer side of the groove is used for the second CNC processing to form the anisotropic boss 16. The vortex cavity is provided with vortex protrusions 12 which are spirally arranged from the center of the outer ring 11 to the outside in sequence, and the vortex protrusions 12 are at a certain distance from the inner wall of the outer ring 11, that is, the vortex protrusions 12 and the inner wall of the outer ring 11 maintain a certain gap, and at the same time, the height of the vortex protrusions 12 is less than the height of the side wall of the outer ring 11, where the height is defined as the distance from the top of the vortex protrusion 12 to the bottom of the groove, and the height of the side wall of the outer ring 11 is defined as the distance from the top of the outer ring 11 to the bottom of the outer ring 11.

[0048] The height of the vortex protrusion 12 is smaller than the height of the outer ring 11, which can facilitate the installation of the vortex disk. Correspondingly, when setting the clamping assembly 21, it is necessary to set it according to the height and structure of the vortex protrusion 12 to ensure that the clamping assembly 21 can fit with the top of the intermediate body and achieve stable clamping of the bottom of the intermediate body. Here, the top of the intermediate body refers to the top of the outer ring 11.

[0049] Furthermore, in the present invention, the top of the vortex protrusion 12 is flush with the bottom of the notch 13 , and the bottom of the notch 13 refers to the side of the notch 13 close to the bottom of the outer ring 11 .

[0050] The notch 13 and the vortex protrusion 12 in the scroll plate are designed to facilitate installation and compressor operation. On this basis, the structure of the clamping assembly 21 needs to be designed according to the position and structure of the vortex protrusion 12 and the notch 13 to ensure that the clamping assembly 21 can fit with the notch 13 at the top of the intermediate body, the vortex protrusion 12 and the top of the outer ring 11, and achieve stable clamping of the bottom of the intermediate body.

[0051] Correspondingly, such as Figure 4 and Figure 5 As shown, the placement groove of the utility model includes an annular groove 22 and a limiting boss 24 located inside the annular groove 22, and the annular groove 22 is provided with a limiting boss 23 adapted to the notch 13 in the intermediate body, and the top of the limiting boss 23 is flush with the limiting boss 24; when the intermediate body is placed in the placement groove, the outer ring 11 is located in the annular groove 22, the vortex boss 12 abuts against the limiting boss 24, and the notch 13 abuts against the limiting boss 23.

[0052] That is to say, the shape of the annular groove 22 is adapted to the outer ring 11. In actual operation, the outer ring 11 is a solid structure with a certain thickness, so the annular groove 22 is an annular groove with a certain width, ensuring that when the outer ring 11 is inverted in the annular groove 22, the shape and size of the annular groove 22 are adapted to the outer ring 11. Inverted here means that the top of the outer ring 11 is placed downward in the annular groove 22, so that the bottom outer side of the outer ring 11 can be exposed outside the clamping assembly 21, which is convenient for the second CNC processing of the bottom outer side.

[0053] When the outer ring 11 is buckled in the annular groove 22, the top of the vortex protrusion 12 inside the outer ring 11 abuts against the limiting boss 24 inside the annular groove 22. It can be understood that the placement groove is a cylindrical groove located in the clamping component 21, and a limiting boss 24 with a smaller radius is set in the cylindrical groove. The gap between the limiting boss 24 and the inner side wall of the cylindrical groove is the annular groove 22. The distance between the limiting boss 24 and the bottom of the cylindrical groove is equal to the distance between the top of the vortex protrusion 12 in the intermediate body and the top of the outer ring 11. In this way, when the outer ring 11 is buckled in the annular groove 22, the top of the outer ring 11 abuts against the bottom of the annular groove 22, and the top of the vortex protrusion 12 abuts against the limiting boss 24.

[0054] At the same time, a limiting protrusion 23 is provided in the annular groove 22, and the shape and position of the limiting protrusion 23 are adapted to the notch 13 in the intermediate outer ring 11, and the top of the limiting protrusion 23 is flush with the top of the limiting protrusion 23. It is ensured that when the outer ring 11 is buckled in the annular groove 22, the limiting protrusion 23 abuts against the side wall of the notch 13 in the outer ring 11. Since the bottom of the notch 13 is flush with the top of the vortex protrusion 12, the limiting protrusion 23 and the limiting boss 24 are set to have the same height, which can ensure that the vortex protrusion 12 abuts against the limiting boss 24, and the notch 13 abuts against the limiting protrusion 23.

[0055] The shape of the notch 13 in the present invention is also fully compatible with the shape of the limiting protrusion 23. For example, when the notch 13 is a U-shaped notch 13, the shape of the limiting protrusion 23 also corresponds to a U-shaped structure, ensuring that the limiting protrusion 23 fits and abuts against the bottom side wall and the end side walls of the notch 13 in the outer ring 11.

[0056] By setting the above-mentioned annular groove 22, limiting protrusion 23 and limiting boss 24, it can be ensured that when the top of the intermediate body is placed downward in the placement groove, the outer ring 11 is adapted and snap-fitted with the annular groove 22, the notch 13 is adapted and snap-fitted with the limiting protrusion 23, and the vortex protrusion 12 is adapted and snap-fitted with the limiting boss 24, so that the clamping component 21 and the top of the intermediate body can be fitted and snap-fitted.

[0057] On the basis of the above-mentioned clamping, the fasteners in the clamping assembly 21 fasten the limiting through holes 15 in the side walls of the outer ring 11, so that the clamping assembly 21 can achieve precise clamping and stable fixation of the intermediate body. Due to the precise clamping of the annular groove 22, the limiting protrusion 23 and the limiting boss 24 on various parts of the intermediate body, it is ensured that the clamping assembly 21 will not undergo relative displacement during the process of clamping the intermediate body, thereby ensuring the stability of the clamping process.

[0058] Furthermore, positioning grooves 26 away from the center of the annular groove 22 are provided on both sides of the limiting protrusion 23 in the circumferential direction of the utility model.

[0059] Here, the circumferential sides refer to the circumferential direction of the annular groove 22. The two sides of the limiting protrusion 23 are provided with positioning grooves 26 away from the center of the annular groove 22. Figure 4 and Figure 5 As shown. The function of the positioning groove 26 is to facilitate the placement of the intermediate. When the intermediate is placed in the placement groove, if the annular groove 22 is adapted to the outer ring 11, it is necessary to clamp the bottom of the outer ring 11 and place it in the annular groove 22. During the movement of the intermediate, the intermediate is prone to sliding, or as the outer ring 11 penetrates into the annular groove 22, the position of the intermediate subject to the clamping force gradually decreases, which is not conducive to the clamping of the intermediate. The utility model sets positioning grooves 26 on both sides of the limiting protrusion 23, which can ensure that when the outer ring 11 enters the annular groove 22, the side wall of the outer ring 11 at the corresponding position of the positioning groove 26 is clamped, and the intermediate is placed in the placement groove under the clamping action. Similarly, after the intermediate completes the second CNC processing, by clamping the outer side of the outer ring 11 at the positioning groove 26, that is, the outer side of the outer ring 11 at the positioning groove 26 is used as the force point, the intermediate can be quickly taken out from the clamping assembly 21. Therefore, the positioning groove 26 located away from the center of the annular groove 22 can realize convenient assembly and separation between the intermediate body and the clamping assembly 21, thereby improving the clamping and disassembly efficiency of the intermediate body.

[0060] In order to facilitate the processing and formation of the positioning groove 26, the utility model can also simultaneously set positioning grooves 26 close to the center of the annular groove 22 on both sides of the circumferential direction of the limiting protrusion 23. When the intermediate body is placed in the placement groove, the positioning groove 26 close to the center of the annular groove 22 will be covered by the outer ring 11, such as Figure 6 As shown, only the positioning groove far from the center of the annular groove 22 is located outside the outer ring 11. The positioning groove 26 near the center of the annular groove 22 and the positioning groove 26 far from the center of the annular groove 22 form a symmetrical structure. After the annular groove 22 is formed, the expansion structure can be used to expand both sides uniformly, which can improve the forming efficiency of the positioning groove 26.

[0061] Example 3

[0062] like Figure 4-Figure 8 As shown, the vortex disk clamping assembly provided by the utility model is provided with a placement groove adapted to the outer ring 11, the placement groove is provided with a limiting protrusion 23 adapted to the notch 13, the side wall of the outer ring 11 is provided with a limiting through hole 15, and the side wall of the placement groove is provided with a fastener adapted to the limiting through hole 15.

[0063] In this embodiment, a positioning protrusion 14 is provided on the outer wall of the outer ring 11, and the distance between the top of the positioning protrusion 14 and the top of the outer ring 11 is greater than the distance between the bottom of the notch 13 and the top of the outer ring 11; when the intermediate is placed in the placement groove, the positioning protrusion 14 is located on the outside of the placement groove.

[0064] The positioning protrusion 14 is located on the outside of the outer ring 11 near the bottom, that is, the positioning protrusion 14 is located below the notch 13. The positioning protrusion 14 is provided to facilitate the positioning and installation of the scroll plate in the compressor. In view of the existence of the limiting protrusion 23, the position of the positioning protrusion 14 also needs to be considered when designing the clamping assembly 21 to ensure that the limiting protrusion 23 does not interfere with the placement groove. Correspondingly, the utility model sets the depth of the placement groove to be equal to the minimum distance from the top of the positioning protrusion 14 to the top of the outer ring 11. That is to say, when the outer ring 11 is placed upside down in the placement groove, the top of the positioning protrusion 14 is flush with the top of the placement groove. Figure 6-Figure 8 shown.

[0065] The depth of the placement groove is adapted to the height of the outer ring 11 above the positioning protrusion 14, so that the outer ring 11 can be just clamped inside the placement groove and the positioning protrusion 14 is exposed on the outside of the placement groove without interfering with the placement groove and affecting the positioning and clamping of the outer ring 11 by the clamping assembly 21.

[0066] Furthermore, the fastener of the utility model comprises a fastening through hole 25 and a fastening screw 27, wherein the fastening through hole 25 passes through the side wall of the clamping assembly 21, and the fastening screw 27 passes through the fastening through hole 25 and the limiting through hole 15. There are a plurality of limiting through holes 15, and the plurality of limiting through holes 15 are evenly distributed along the circumferential direction of the outer ring 11, and the fastening through holes 25 and the limiting through holes 15 in the clamping assembly 21 are arranged one by one.

[0067] When the intermediate body is placed in the placement groove, since the fastening through hole 25 and the limiting through hole 15 correspond one to one, the positioning through hole 15 and the fastening through hole 25 can be ensured to correspond one to one through the adaptation positioning of the notch 13 and the limiting protrusion 23. At this time, the fastening screw 27 is passed through the fastening through hole 25 and the limiting through hole 15 in sequence, and is fixed with a fastening nut, so that the intermediate body and the clamping assembly 21 can be fixed. The fastening through hole 25 and the fastening screw 27 have a simple structure and are easy to install, and can achieve rapid alignment of the fastening through hole 25 and the limiting through hole 15 through the mutual cooperation between the limiting protrusion 23 and the notch 13.

[0068] Furthermore, the limiting through hole 15 and the notch 13 described in the utility model are staggered, and the limiting through hole 15 needs to cooperate with the fastening through hole 25 and the fastening screw 27 to achieve the fixation of the intermediate body and the clamping assembly 21. If the limiting through hole 15 coincides with the notch 13, the position of the fastening screw 27 is uncertain, so it is necessary to set the limiting through hole 15 and the notch 13 in the intermediate body to be staggered.

[0069] As a specific embodiment, in the present invention, four fastening through holes 25 can be provided in the clamping assembly 21 , and the four fastening through holes 25 are evenly distributed at intervals of 90°.

[0070] The outer ring 11 of the intermediate body of the utility model is provided with a vortex cavity, which includes vortex protrusions 12 spirally arranged from the center to the outside of the outer ring 11, the bottom of the vortex protrusion 12 is located inside the bottom of the outer ring 11, and the height of the vortex protrusion 12 is less than the height of the outer ring 11. At the same time, in the utility model, the top of the vortex protrusion 12 is flush with the bottom of the notch 13, and the bottom of the notch 13 refers to the side of the notch 13 close to the bottom of the outer ring 11.

[0071] Correspondingly, such as Figure 4 and Figure 5 As shown, the placement groove of the utility model includes an annular groove 22 and a limiting boss 24 located inside the annular groove 22, and the annular groove 22 is provided with a limiting boss 23 adapted to the notch 13 in the intermediate body, and the top of the limiting boss 23 is flush with the limiting boss 24; when the intermediate body is placed in the placement groove, the outer ring 11 is located in the annular groove 22, the vortex boss 12 abuts against the limiting boss 24, and the notch 13 abuts against the limiting boss 23.

[0072] Furthermore, in order to facilitate the assembly and classification between the intermediate body and the clamping assembly 21 , positioning grooves 26 away from the center of the annular groove 22 are provided on both sides of the circumference of the limiting protrusion 23 of the utility model.

[0073] In order to facilitate the one-step forming of the positioning groove 26 , the utility model can also provide positioning grooves 26 close to the center of the annular groove 22 on both sides of the limiting protrusion 23 in the circumferential direction.

[0074] Example 4

[0075] The difference from Example 3 is that the placement groove in the clamping component 21 is a hollow structure, and the limiting protrusion 23 and the limiting boss 24 that are the same as those in Examples 2 and 3 are arranged in the hollow structure. At the same time, since the placement groove is a hollow structure, the annular groove 22 in Examples 2 and 3 is an annular through hole structure.

[0076] In this structure, the fastening screw 27 can pass through the clamping assembly 21 and the outer ring 11 and be exposed in the hollow position, which is convenient for installing and fixing the fastening screw 27 and the fastening nut.

[0077] In this structure, the limiting protrusion 23 is provided with a positioning groove 26 away from the center of the annular groove 22 and a positioning groove 26 close to the center of the annular groove 22 on both sides of the circumference. At this time, both the positioning groove 26 close to the center of the annular groove 22 and the positioning groove 26 away from the center of the annular groove 22 can be used as a force point for the outer ring 11 to clamp the outer ring 11 and facilitate its placement in the placement groove.

[0078] It is the same as structural embodiments 2 and 3 and will not be described in detail here.

[0079] The utility model also provides a scroll disk processing device, including a scroll disk clamping assembly as described above, which is used to clamp the intermediate body after the first CNC processing, and at the same time, the notch 13 is limited and fixed by a limiting protrusion 23, and the limiting through hole 15 is fixed by a fastener, so that the outer side of the bottom of the outer ring 11 is exposed, which is convenient for the second CNC processing of the intermediate body to form an anisotropic boss 16 on the outer side of the bottom of the outer ring 11, thereby improving the accuracy of CNC processing of the scroll disk.
