Description
Technical Field

[0002] This section merely provides background information related to the present disclosure and may not constitute prior art.
[0003] The scroll compressor is an important component of the air conditioning system of new energy vehicles, and one of its core components is the scroll disk. The machining accuracy of the scroll disk directly affects the performance of the compressor and the efficiency of the entire air conditioning system, so the scroll disk has extremely high machining accuracy requirements. In actual production, higher requirements are also placed on the machining efficiency of the scroll disk.
[0004] The traditional scroll disk processing adopts the V-block positioning method, and the V-block is used to clamp and position the outer cylindrical surface of the scroll disk. The outer cylindrical surface of the scroll disk is not rigid enough, and the scroll disk is prone to slight deformation under the clamping force of the V-block. This deformation will cause the actual axis of the scroll disk to deviate from the theoretical axis, resulting in positioning errors; the short outer cylindrical surface of the scroll disk has a small contact area on the V-block and fewer support points. The scroll disk cannot be evenly stressed during the clamping process, causing the scroll disk to be more easily offset when subjected to external forces; if the angle or surface accuracy of the V-block is not high enough, it will also cause the scroll disk to tilt during the clamping process, causing the scroll disk axis to be non-parallel to the positioning cylindrical surface.

[0015] A scroll disk processing technology, which is performed based on the scroll disk processing system, comprises the following steps: S1. Positioning the scroll on the scroll processing tooling; S2. Install the scroll disk processing tooling on the platform of the five-axis vertical machining center, use the five-axis vertical machining center to process one side of the scroll disk, then use the platform of the five-axis vertical machining center to drive the scroll disk processing tooling to flip 180°, and use the five-axis vertical machining center to process the other side of the scroll disk.

[0019] The technical solution of the present invention has the following advantages: 1. The scroll processing tool provided by the present invention uses an elastic sleeve to wrap and clamp the cylindrical positioning part of the entire scroll, so that the pressure distribution between the scroll and the elastic sleeve is uniform. The elastic sleeve has a large contact area with the cylindrical positioning part of the scroll, and can provide support at multiple points. The position of the scroll during the processing is more stable, reducing the processing error caused by inaccurate positioning. The elastic sleeve will produce a certain self-locking effect during the clamping process, and can maintain a good clamping state even if it is disturbed by external vibration or other external forces.
[0020] The present invention uses a clamping structure to press down the elastic sleeve assembled in the first tapered hole, so that the clamping hole of the elastic sleeve uniformly clamps the cylindrical positioning part of the scroll plate in the circumferential direction, and the scroll plate is uniformly stressed during the clamping process; the axis of the scroll plate after being clamped and positioned is colinear with the axis of the elastic sleeve, and there is no problem of clamping deviation, ensuring that the scroll plate is accurately positioned inside the elastic sleeve. Through precise positioning and uniform clamping force, this tooling can ensure the consistency of the processing quality of each scroll plate, thereby improving the overall quality of the product.
[0021] The present invention can change the clamping force of the elastic sleeve on the scroll by adjusting the force of the clamping structure, so that the tooling can adapt to scrolls of different sizes and shapes, thereby improving the versatility and flexibility of the tooling. In addition, by changing the clamping force of the elastic sleeve on the scroll, it is also possible to avoid deformation or damage of the scroll caused by excessive clamping of the elastic sleeve on the scroll.
[0022] The design of this tool is relatively simple and easy to operate and maintain. The operator only needs to adjust the clamping structure to complete the clamping of the scroll plate, without complicated operation steps, which improves production efficiency. Since the elastic sleeve can clamp adaptively, the clamping process is fast and reliable, reducing the clamping time, thereby improving overall production efficiency.
[0023] 2. The front and back sides of the scroll disk processing tooling provided by the present invention are exposed, and the clamping body is installed on the platform of the five-axis vertical machining center through the zero-point positioning system. After the five-axis vertical machining center completes the processing of one side of the scroll disk, the five-axis vertical machining center drives the scroll disk to rotate 180°, so that the other side of the scroll disk can face the tool, and the tool is used to process the other side of the scroll disk. The present invention utilizes the characteristics of the elastic sleeve and cooperates with the five-axis vertical machining center. When processing the front and back sides of the scroll disk, it is not necessary to disassemble the scroll disk from the tooling and reassemble it, avoiding installation errors caused by multiple installations, realizing double-sided processing of the scroll disk without stopping the machine, and improving the processing accuracy.
[0024] 3. In the scroll processing tooling provided by the present invention, the position where the clamping nut and the elastic sleeve abut against each other is set as a second tapered hole, the position where the elastic sleeve and the clamping nut abut against each other is set as a tapered portion, and the second tapered hole is adapted to the tapered portion. The generatrix of the second tapered hole is perpendicular to the generatrix of the first tapered hole. On the first hand, it can ensure that the clamping force is evenly distributed in multiple directions, which helps to avoid deformation or damage of the scroll due to excessive unidirectional force. On the second hand, when the clamping nut is tightened, the contact area between the second tapered hole and the tapered portion gradually increases, thereby increasing the friction force, making the clamping more stable and maintaining a good clamping state. On the third hand, the cooperation between the second tapered hole and the tapered portion can provide support at multiple points, enhance the rigidity of the entire tooling system, better resist the action of external forces, and further ensure the positioning accuracy and processing stability of the scroll.
[0025] 4. The scroll processing tool provided by the present invention is provided with a plurality of circumferentially evenly arranged gaps on the elastic sleeve, and each gap points to the center of the elastic sleeve. The provided gaps enable the inner diameter of the elastic sleeve to change when the elastic sleeve is placed in the first tapered hole and moves along the first tapered hole, and the elastic sleeve can automatically adjust its inner diameter size during the clamping process to accommodate scrolls of different diameters. Due to the presence of the gaps, the elastic sleeve can distribute pressure more evenly during the clamping process, which helps to ensure that the cylindrical positioning portion of the scroll is evenly and firmly clamped, reducing damage or deformation caused by excessive local force.
[0026] 5. In the scroll processing tool provided by the present invention, a positioning plate is detachably provided at one end of the clamp body relative to the clamping structure. At least one positioning protrusion is provided on the end surface of the positioning plate relative to the scroll, and the at least one positioning protrusion is suitable for positioning the back hole of the scroll so that the scroll is positioned and fixed in the elastic sleeve, thereby ensuring the coaxiality of the scroll and the elastic sleeve, and ensuring the accuracy of the installation of the scroll through the positioning plate.
[0027] 6. The scroll disk processing system provided by the present invention combines a five-axis vertical machining center with a scroll disk processing tooling, and can realize double-sided processing of the front and back sides of the scroll disk without stopping the machine, avoiding installation errors caused by multiple installations of the scroll disk, and improving the processing accuracy and efficiency of the scroll disk.
[0028] 7. In the scroll disk processing technology provided by the present invention, the entire scroll disk processing tooling is installed on the zero-point positioning system and the pallet. The scroll disk blank installed at the automatic line installation station is dispatched by the AGV trolley, manipulator, and MES system to the designated five-axis vertical machining center for processing. The processing machine tool does not stop, which reduces auxiliary time and improves processing efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

These terms may only be used to distinguish one element, component, region, layer or section from another region, layer or section.

For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.
[0035] It should be noted that the "front side of the scroll disk" refers to the side with the profile line. Fig.15 As shown in the figure, "the back side of the scroll disk" refers to the side where the back holes of the scroll disk are arranged. The cylindrical positioning part of the scroll disk is close to the back side of the scroll disk, combined with Fig.16 shown.
[0036] The scroll compressor is an important component of the air conditioning system of new energy vehicles, and one of its core components is the scroll disk. The machining accuracy of the scroll disk directly affects the performance of the compressor and the efficiency of the entire air conditioning system, so the scroll disk has extremely high machining accuracy requirements. In actual production, higher requirements are also placed on the machining efficiency of the scroll disk.
[0037] The traditional scroll disk processing adopts the V-block positioning method, and the V-block is used to clamp and position the outer cylindrical surface of the scroll disk. The outer cylindrical surface of the scroll disk is not rigid enough, and the scroll disk is prone to slight deformation under the clamping force of the V-block. This deformation will cause the actual axis of the scroll disk to deviate from the theoretical axis, resulting in positioning errors; the short outer cylindrical surface of the scroll disk has a small contact area on the V-block and fewer support points. The scroll disk cannot be evenly stressed during the clamping process, causing the scroll disk to be more easily offset when subjected to external forces; if the angle or surface accuracy of the V-block is not high enough, it will also cause the scroll disk to tilt during the clamping process, causing the scroll disk axis to be non-parallel to the positioning cylindrical surface.
[0038] Based on this, the present invention proposes a scroll disk processing tooling. In order to solve the problem that the outer cylindrical surface of the aluminum alloy scroll disk that is precisely processed and positioned is short and lacks rigidity, an elastic sleeve is designed to clamp the entire cylindrical surface of the scroll disk, thus solving the problem of insufficient rigidity and inaccurate positioning of the outer cylindrical surface of the scroll disk.
[0039] Traditional scroll disks use three-axis vertical machining centers to do fine machining on the front and back sides of the scroll disk. After completing the machining of one side of the scroll disk, the scroll disk needs to be removed from the tooling and installed with the other side of the scroll disk facing the machining device to machine the other side of the scroll disk. This causes the scroll disk to be machined multiple times, which can easily lead to installation errors. In addition, there are reference requirements for the front and back sides of the scroll disk during machining. When the scroll disk is clamped again after being disassembled, it is easy to cause different clamping positions and large position errors. The CPK value of the scroll disk's position accuracy is not high under increasingly stringent requirements. The use of a three-axis vertical machining center to machine scroll disks is usually done manually for loading and unloading, and the machining efficiency needs to be improved.
[0040] In order to improve the processing accuracy and efficiency of the scroll disk, the present invention proposes a scroll disk processing tooling, in which the front and back sides of the scroll disk are exposed, and the clamp body is installed on the platform of the five-axis vertical machining center through a zero-point positioning system. After the five-axis vertical machining center completes processing on one side of the scroll disk, the C-axis on the platform of the five-axis vertical machining center can be used to drive the scroll disk processing tooling and the scroll disk to rotate 180°, so that the other side of the scroll disk can face the tool, and the two sides of the scroll disk can be processed by the tool. When processing the front and back sides of the scroll disk, there is no need to disassemble the scroll disk from the tooling and reassemble it, thereby avoiding installation errors caused by multiple installations.
[0041] The specific embodiments of the present invention are described in detail below in conjunction with the scroll disk processing tooling of the first aspect of the present invention, the scroll disk processing system of the second aspect of the present invention, and the scroll disk processing process of the second aspect of the present invention.
[0042] Example 1 It should be noted that the scroll disk processing tooling of the first aspect of the present invention is only a preferred embodiment of the present invention, and the scroll disk of the present invention can be positioned by using the scroll disk processing tooling of the first aspect of the present invention, and can also be positioned by using other tooling.
[0043] Combination Figures 1 to 14 As shown, this embodiment discloses a scroll disk processing tooling, specifically for precision machining of scroll disk parts of scroll compressors for new energy vehicles on a five-axis vertical machining center production line, including a clamping body 1, an elastic sleeve 2, and a clamping structure 3.
[0044] The clamp body 1 is provided with a first tapered hole 11. The outside of the elastic sleeve 2 is adapted to the first tapered hole 11 and is at least partially positioned in the first tapered hole 11. The inside of the elastic sleeve 2 is provided with a clamping hole 21, which is used to position the cylindrical positioning portion 51 of the scroll. The axis of the first tapered hole 11, the axis of the clamping hole 21 and the axis of the scroll are collinear, which ensures the accurate positioning of the scroll 5 in the clamp body, can effectively reduce the positioning error, and improve the position accuracy of the scroll.
[0045] The clamping structure 3 is arranged on the clamping body 1, and the clamping structure 3 uniformly applies force to the end of the elastic sleeve 2 away from the first conical hole, so that the elastic sleeve 2 can move along the first conical hole 11 to adjust the size of the clamping hole 21 of the elastic sleeve 2 and the clamping force of the elastic sleeve 2 on the cylindrical positioning part 51 of the swirl disk.
[0046] The above-mentioned scroll processing tooling uses the elastic sleeve 2 to wrap and clamp the cylindrical positioning part 51 of the entire scroll, so that the pressure distribution between the scroll and the elastic sleeve 2 is uniform. The elastic sleeve 2 has a large contact area with the cylindrical positioning part 51 of the scroll, and can provide support at multiple points. The position of the scroll during the processing is more stable, reducing the processing error caused by inaccurate positioning. The elastic sleeve 2 will produce a certain self-locking effect during the clamping process, and can maintain a good clamping state even if it is disturbed by external vibration or other external forces.
[0047] The above-mentioned scroll processing tooling uses the clamping structure 3 to press down the elastic sleeve 2 assembled in the first tapered hole 11, and the clamping hole 21 of the elastic sleeve 2 uniformly clamps the cylindrical positioning part 51 of the scroll 5 in the circumferential direction, and the scroll 5 is uniformly stressed during the clamping process; the axis of the scroll 5 after being clamped and positioned is colinear with the axis of the elastic sleeve 2, and there is no problem of clamping deviation, ensuring that the scroll 5 is accurately positioned inside the elastic sleeve 2. Through precise positioning and uniform clamping force, this tooling can ensure the consistency of the processing quality of each scroll, thereby improving the overall quality of the product.
[0048] By adjusting the force of the clamping structure 3, the clamping force of the elastic sleeve 2 on the scroll can be changed, so that the tooling can adapt to scrolls of different sizes and shapes, improving the versatility and flexibility of the tooling. In addition, by changing the clamping force of the elastic sleeve 2 on the scroll, it is also possible to avoid deformation or damage of the scroll caused by excessive clamping of the elastic sleeve 2 on the scroll.
[0049] The design of the tooling is relatively simple and easy to operate and maintain. The operator only needs to adjust the clamping structure 3 to complete the clamping of the scroll disk, without complicated operating steps, thereby improving production efficiency. Since the elastic sleeve 2 can be clamped adaptively, the clamping process is fast and reliable, reducing the clamping time, thereby improving the overall production efficiency.
[0050] In some embodiments, the first tapered hole 11 passes through the clamp body 1 so that when the scroll disk is positioned on the clamp body 1, the front and back sides of the scroll disk are exposed. The clamp body 1 is disposed on a zero-point positioning system 7, and the zero-point positioning system 7 is suitable for being connected to a platform of a five-axis vertical machining center so as to process the front and back sides of the scroll disk respectively through the five-axis vertical machining center. The zero-point positioning system 7 includes a positioning disk and a positioning shaft 71, wherein the positioning shaft 71 is perpendicular to the axis of the elastic sleeve 2. A position for connecting with the positioning shaft 71 is provided on the five-axis vertical machining center so that the positioning shaft 71 can be installed thereon.
[0051] In this embodiment, the front and back sides of the scroll disk are exposed, and the clamp body 1 is installed on the platform of the five-axis vertical machining center through the zero-point positioning system 7. The platform of the five-axis vertical machining center has an X-axis, a Y-axis, a Z-axis, an A-axis and a C-axis, wherein the C-axis can drive the scroll disk processing tooling and the scroll disk to rotate. After the five-axis vertical machining center completes the processing of one side of the scroll disk, the C-axis on the platform of the five-axis vertical machining center can drive the scroll disk processing tooling and the scroll disk to rotate 180°, so that the other side of the scroll disk can face the tool, and the tool can be used to process the other side of the scroll disk. This embodiment utilizes the characteristics of the elastic sleeve 2 and cooperates with the five-axis vertical machining center. When processing the front and back sides of the scroll disk, it is not necessary to disassemble the scroll disk from the tooling and reassemble it, thereby avoiding installation errors caused by multiple installations, realizing double-sided processing of the scroll disk without stopping the machine, and improving the processing accuracy.
[0052] In some embodiments, Fig. 9 As shown, the clamp body 1 is provided with a threaded hole 12 connected to the first tapered hole 11. The clamping structure 3 includes a clamping nut 31, which is assembled in the threaded hole 12 and abuts against the end of the elastic sleeve 2 away from the first tapered hole. Fig.10 As shown, a through hole 311 is provided in the middle of the clamping nut 31, through which the scroll 5 can pass. In this embodiment, the clamping structure 3 is configured to perform threaded compression on the elastic sleeve 2, that is, when the clamping nut 31 rotates in the threaded hole 12, the clamping nut 31 can compress the elastic sleeve 2. In the process of clamping the elastic sleeve 2, the force applied by the clamping nut 31 to the elastic sleeve 2 is perpendicular to the axis of the elastic sleeve 2, and thus, in the process of rotating the clamping nut 31, the scroll inside the elastic sleeve 2 will not be affected.
[0053] In some embodiments, the clamping nut 31 is provided with a plurality of clamping grooves 33 around its circumference. Figure 4 and Figure 8As shown, the clamping nut 31 is rotated by the clamping spanner 32, and the clamping spanner 32 is matched with the clamping groove 33. In this embodiment, the clamping nut 31 can be rotated very conveniently by the clamping spanner 32, and after the installation of the clamping nut 31 is completed, the clamping spanner 32 can be quickly separated from the clamping nut 31.
[0054] In some embodiments, Fig.11 As shown, the position where the clamping nut 31 abuts against the elastic sleeve 2 is set as a second tapered hole 312; Fig.12 As shown, the position where the elastic sleeve 2 abuts against the clamping nut 31 is set as the tapered portion 22, and the second tapered hole 312 is adapted to the tapered portion 22. The generatrix of the second tapered hole 312 is perpendicular to the generatrix of the first tapered hole 11. On the one hand, when the clamping nut 31 applies pressure to the tapered portion 22 of the elastic sleeve 2 through the second tapered hole 312, since the generatrix of the second tapered hole 312 is perpendicular to the generatrix of the first tapered hole 11, it can ensure that the clamping force is evenly distributed in multiple directions, which helps to avoid deformation or damage of the scroll disk caused by excessive unidirectional force. On the other hand, when the clamping nut 31 is tightened, the contact area between the second tapered hole 312 and the tapered portion 22 gradually increases, thereby increasing the friction force and making the clamping more stable. Even if it is disturbed by vibration or other external forces during the processing, it can maintain a good clamping state. Thirdly, the cooperation between the second tapered hole 312 and the tapered portion 22 can provide support at multiple points, thereby enhancing the rigidity of the entire tooling system, being able to better resist the effects of external forces, and further ensuring the positioning accuracy and processing stability of the scroll disk.
[0055] In some embodiments, the elastic sleeve 2 is provided with a plurality of gaps 23 evenly arranged in the circumferential direction, and each gap 23 points to the center of the elastic sleeve 2. In this embodiment, the gaps 23 are provided so that when the elastic sleeve 2 is placed in the first tapered hole 11 and moves along the first tapered hole 11, the inner diameter of the elastic sleeve 2 can change, and the elastic sleeve 2 can automatically adjust its inner diameter size during the clamping process to adapt to scrolls of different diameters. Due to the presence of the gaps 23, the elastic sleeve 2 can distribute pressure more evenly during the clamping process, which helps to ensure that the cylindrical positioning portion 51 of the scroll is evenly and firmly clamped, and reduce damage or deformation caused by excessive local force.
[0056] More specifically, the gap 23 includes a first gap and a second gap, the first gap is arranged at the top of the elastic sleeve 2, and the second gap is arranged at the bottom of the elastic sleeve 2, and the first gap and the second gap are evenly spaced and arranged on the elastic sleeve 2.
[0057] In some embodiments, at least one positioning groove 24 is provided on the inner side wall of the elastic sleeve 2, and an elastic collar 4 is embedded in the positioning groove 24. The elastic collar 4 is exposed from the positioning groove 24, supports the elastic sleeve 2, and limits the bottom of the elastic sleeve 2, ensuring that the elastic sleeve 2 does not move in the axial direction during the clamping process and keeps it in the correct position. The elastic collar 4 axially limits the scroll disk, and when the scroll disk is positioned on the elastic collar 4, the axial position of the scroll disk can be guaranteed. In addition, the elastic collar 4 is exposed from the positioning groove 24, which can provide radial support for the elastic sleeve 2, and can prevent the elastic sleeve 2 from excessive deformation or collapse during the clamping process, thereby maintaining its shape and stability. Through the limiting effect of the elastic collar 4, it can be ensured that the elastic sleeve 2 is always at the correct height and position during the clamping process, which helps to improve the clamping accuracy and consistency of the scroll disk.
[0058] Among them, Fig.14 As shown, the elastic collar 4 includes a semi-annular collar 41 and a clamping plate 42. Two clamping plates 42 are provided, which are respectively arranged at the ends of the semi-annular collar 41. The semi-annular collar 41 can protrude from the positioning groove 24 to limit the scroll plate.
[0059] In some embodiments, Figure 6 and Figure 7 As shown, a positioning plate 6 is detachably provided at one end of the clamp body 1 relative to the clamping structure 3. More specifically, at least one pin hole 62 is provided on the positioning plate 6, and at least one positioning pin 13 is provided on the bottom surface of the clamp body 1. When the positioning pin 13 is inserted into the pin hole 62, the positioning plate 6 and the clamp body 1 can be positioned; when the positioning pin 13 is disengaged from the pin hole 62, the positioning plate 6 and the clamp body 1 can be separated. At least one positioning protrusion 61 is provided on the end surface of the positioning plate 6 relative to the scroll disk. At least one positioning protrusion 61 is suitable for positioning the back hole of the scroll disk so that the scroll disk is positioned and fixed in the elastic sleeve 2, thereby ensuring the coaxiality of the scroll disk and the elastic sleeve 2. In this embodiment, before the scroll disk 5 is installed to the elastic sleeve 2, the positioning plate 6 can be installed at the bottom end of the clamp body 1, and the positioning plate 6 is used to ensure the accuracy of the installation of the scroll disk 5.
[0060] As a preferred embodiment, Fig.13 As shown, three positioning protrusions 61 are provided at the top of the positioning plate 6 , and the connecting line of the three positioning protrusions 61 is a triangle. When the three positioning protrusions 61 are positioned with the back holes of the scroll plate 5 , the central axis of the scroll plate 5 is coaxial with the central axis of the elastic sleeve 2 .
[0061] Example 2 It should be noted that the scroll disk processing system of the second aspect of the present invention is only a preferred embodiment of the present invention, and the scroll disk of the present invention can be processed by the scroll disk processing system of the second aspect of the present invention, and can also be processed by other processing systems.
[0062] This embodiment discloses a scroll disk processing system, which is a scroll disk processing system based on a five-axis vertical machining center production line, including a scroll disk processing tool and a five-axis vertical machining center. The platform of the five-axis vertical machining center is suitable for connecting with the scroll disk processing tool during scroll disk processing.
[0063] The scroll disk processing system mentioned above combines a five-axis vertical machining center with a scroll disk processing tooling, and can realize double-sided processing of the front and back sides of the scroll disk without stopping the machine, avoiding installation errors caused by multiple installations of the scroll disk, and improving the processing accuracy and efficiency of the scroll disk.
[0064] The scroll disk processing system further comprises a mounting platform, an AGV trolley, a transfer platform and a manipulator. A tray is placed on the mounting platform.
[0065] The scroll processing tooling is positioned on the tray when the scroll is installed, so that the scroll can be positioned on the tray.
[0066] Since there is a certain distance between the installation platform and the five-axis vertical machining center, in order to realize the automatic transfer of the scroll disk processing tooling with the scroll disk, the present embodiment also provides an AGV trolley, which is used to transfer the pallet and the scroll disk processing tooling on the pallet to the transfer platform. The AGV trolley includes a lifting mechanism and a moving mechanism. When taking the pallet and the scroll disk processing tooling, the lifting mechanism lifts the pallet and the scroll disk processing tooling, and then moves them to the position of the five-axis vertical machining center driven by the moving mechanism. When the AGV trolley moves to the position of the transfer platform, the lifting mechanism descends, places the pallet on the transfer platform, and then the AGV trolley returns to the initial position.
[0067] The transfer platform is set near the five-axis vertical machining center and is used to temporarily store the pallet and scroll plate processing tools.
[0068] The manipulator is used to clamp the scroll disc processing tooling on the transfer platform to the five-axis vertical machining center and install the scroll disc processing tooling on the platform of the five-axis vertical machining center. The manipulator is a common structure on the market, and its specific structure is not described here.
[0069] Example 3 It should be noted that the scroll disk processing technology of the third aspect of the present invention is only a preferred embodiment of the present invention. The scroll disk of the present invention can be processed by the scroll disk processing technology of the third aspect of the present invention, and can also be processed by other methods. For the convenience of explanation, the specific processing process of the scroll disk of the present invention is explained below through the scroll disk processing technology of the third aspect of the present invention.
[0070] Combination Figures 1 to 14 As shown, this embodiment discloses a scroll disk processing process, which is based on a scroll disk processing system and includes the following steps: S1. Position the scroll 5 on the scroll processing tooling.
[0071] Step S1 specifically includes the following steps: The scroll plate 5 is placed in the clamping hole 21 of the elastic sleeve 2 .
[0072] The clamping wrench 32 is clamped into the clamping groove 33 of the clamping nut 31, and the clamping nut 31 is rotated by the clamping wrench 32 to move the clamping nut 31 toward the elastic sleeve 2, thereby squeezing the elastic sleeve 2, and the elastic sleeve 2 clamps the cylindrical positioning portion 51 of the scroll.
[0073] When the elastic sleeve 2 is adjusted to the right position, the clamping wrench 32 is disengaged from the clamping slot 33 .
[0074] In step S1, before placing the scroll plate 5 into the clamping hole 21 of the elastic sleeve 2, a positioning plate 6 is installed at one end of the clamp body 1 opposite to the clamping structure 3; When the scroll 5 is placed in the clamping hole 21 of the elastic sleeve 2, the positioning protrusion 61 on the positioning plate 6 is used to position the back hole of the scroll, so that the scroll can be accurately positioned to the set position in the elastic sleeve 2 each time it is installed; After the scroll 5 is placed in the clamping hole 21 of the elastic sleeve 2, the positioning plate 6 is removed to expose the front and back surfaces of the scroll 5.
[0075] S2. Install the scroll disk processing tooling on the platform of the five-axis vertical machining center, use the five-axis vertical machining center to process one side of the scroll disk 5, then use the platform of the five-axis vertical machining center to drive the scroll disk processing tooling to flip 180°, and use the five-axis vertical machining center to process the other side of the scroll disk 5.
[0076] Step S2 specifically includes the following steps: Combination Fig.16, use a five-axis vertical machining center to semi-finish the back side of the scroll plate 5; semi-finish the first back side hole 53 of the scroll plate 5, finish the sealing groove 56, finish the first back side hole 53, and then finish the second back side hole 54 and the third back side hole 55 respectively; then finish the back side of the scroll plate 5; finish the outer circle of the cylindrical positioning part 51 of the scroll plate 5.
[0077] The scroll plate processing tooling is turned 180° through the platform of the five-axis vertical machining center.
[0078] Combination Fig.15 , use a five-axis vertical machining center to finish the mold line head step 58 on the front side of the scroll plate 5; semi-finish the mold line head 59; use the interpolation method or the development method to semi-finish the mold line 510, and finish the mold line 510; finish the bottom of the mold line.
[0079] In the above scroll disk processing technology, the entire scroll disk processing tooling is installed on the zero-point positioning system and the pallet. The scroll disk blank installed at the automatic line installation station is dispatched by the AGV trolley, manipulator, and MES system to the designated five-axis vertical machining center for processing. The processing machine tool does not stop, which reduces auxiliary time and improves processing efficiency.
[0080] Obviously, the above embodiments are merely examples for clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from them are still within the protection scope of the invention.
