Description

Technical Field

[0001] This invention relates to the technical field of machining thin-walled, large-diameter ring parts, and particularly to a method, apparatus, and vertical machining center for machining thin-walled hanging rings based on a vertical machining center. Background Technology

[0002] Thin-walled ring parts are a common type of mechanical part. The diameter of typical thin-walled ring parts is mostly within 800mm. The existing machining method is to use a three-axis horizontal machining center to process them. However, it has been found that this method often has the disadvantages of difficult clamping, easy deformation, and the need for multiple clampings, which cannot complete the machining in one clamping and has low processing efficiency.

[0003] Furthermore, with the increasing demands of usage, existing conventional thin-walled ring parts within 800mm cannot meet the needs of users. Therefore, the demand for thin-walled large-diameter ring parts is more urgent, especially the application of thin-walled large-diameter ring parts with a diameter of over 800mm and a wall thickness of 5mm is extremely widespread.

[0004] However, due to the small size of the worktable in a three-axis horizontal machining center, it is impossible to machine such thin-walled, large-diameter ring-shaped parts. Furthermore, the aforementioned defects of three-axis horizontal machining centers also prevent the machining of such thin-walled, large-diameter ring-shaped parts. While existing five-axis machining centers can machine such thin-walled, large-diameter ring-shaped parts, machining on a five-axis machining center presents challenges such as high cost and deformation (thin-wall) during the machining process, affecting the manufacturing quality and production efficiency of the parts.

[0005] Therefore, there is an urgent need to develop a method, apparatus, and vertical machining center for machining thin-walled hanging rings based on a vertical machining center that overcomes the above-mentioned defects. Summary of the Invention

The blank thin-walled hanging ring 2 includes a top 21, a bottom 22, and a middle portion 23. The two ends of the middle portion 23 are respectively connected to the top 21 and the bottom 22. The outer surfaces S211 and S221 of the top 21 and the bottom 22 protrude from the outer surface S231 of the middle portion 23. The vertical machining center 1 is a three-axis vertical machining center. The thin-walled hanging ring machining method uses a thin-walled hanging ring machining device 3 based on the three-axis vertical machining center 1 to process the blank thin-walled hanging ring 2 to obtain a finished thin-walled hanging ring.

The base 31 is mounted on the worktable 11 of the three-axis vertical machining center, and the rotary table 32 is rotatably mounted on the base 31. The thin-walled hanging ring machining method includes: Inner and outer contour machining step S1: Set the blank thin wall hanging ring 2 on the rotary table 32 and fix the rotary table 32 to the base 31 through the first fixing member, and rough mill the blank thin wall hanging ring 2 through the three-axis vertical machining center 1; Outer surface machining step S2: Remove the first fixing member and rotate the rotary table 32 to rotate the blank thin-wall hanging ring 2 to a machining position to align with the L-shaped side milling head 33 of the three-axis vertical machining center 1, and perform fine milling on the outer surface S231 of the middle part 23 through the L-shaped side milling head 33. Inner side machining step S3: Adjust the L-shaped side milling head 33 to align with the inner side S232 of the middle part 23, and perform fine milling on the inner side S232 of the middle part 23 using the L-shaped side milling head 33; End face machining step S4: Adjust the L-shaped side milling head 33 to perform fine milling on the end faces of the top 21 and the bottom 22.

[0029] The inner and outer contour processing step S1 includes: The base 31 is fixed on the workbench 11, and the rotary table 32 is installed on the base 31 and then fixed to the base 31 by the first fixing member.

The positioning pin hole 311 and the positioning part 321 are connected by a positioning pin to lock the rotary table 32 onto the base 31.

[0031] Further, the outer surface processing step S2 includes: The blank thin-walled hanging ring 2 is fixed to the rotary table 32 by the second fastener cooperating with the threaded holes 211 and 221; Remove the first bar cutter 13 and install the L-shaped side milling head 33 on the spindle 12, then install the first bar cutter 13 on the L-shaped side milling head 33; Remove the first fixing component and rotate the rotary table 32 to drive the blank thin-wall hanging ring 2 to the processing position to align with the L-shaped side milling head 33; The outer surface S231 of the middle part 23 is precision milled using the first cutting tool 13 on the L-shaped side milling head 33.

[0032] It should be noted that in this embodiment, the second fixing member is a bolt, which is a preferred implementation. The threaded holes 211 and 221 are connected to the threaded hole 323 of the rotary table 32 by the bolt. For example, when the top is on top, the threaded hole at the bottom is connected to the threaded hole 323, and when the bottom is on top, the threaded hole at the top is connected to the threaded hole 323.

[0033] It is worth noting that, in this embodiment, the threaded holes 323 of the rotary table 32 can be stacked along the circumferential direction, thereby enabling the rotary table to be used for processing more products of different diameters.

[0034] In this embodiment, the outer surface S231 of the middle portion 23 is divided into multiple arc surfaces H1, H2...Hn at intervals. The bottom surface of the rotary table 32 is provided with a groove 322, and the top surface of the base 31 is provided with a slide rail 312. The slide rail 312 cooperates with the groove 322 to allow the rotary table 32 to rotate on the base 31. The step of precision milling the outer surface of the middle portion using the bar cutter on the L-shaped side milling head includes: The first cutting tool 13 is used to perform precision milling on the arc surface H1 corresponding to the machining position; After removing the first fixing member and rotating the rotary table 32 to align the next region arc surface H2 with the processing position, the first fixing member is then installed. The first cutting tool 13 is used to finish mill the next area arc surface H2 corresponding to the machining position until all areas of the arc surface are completed.

[0036] Furthermore, the end face processing step S4 includes: Adjust the L-shaped side milling head 33 to perform fine milling on the end face of the top 21; After removing the second fastener and flipping the blank thin-walled hanging ring 2 so that its bottom 22 faces upward, install the second fastener; Adjust the L-shaped side milling head 33 to perform fine milling on the end face of the bottom 22 to obtain the final thin-walled hanging ring.

[0037] Specifically, the end face of the top 21 includes a top surface S212, a bottom surface S213, and an outer surface S211. After adjusting the L-shaped side milling head 33, the top surface S212, bottom surface S213, and outer surface S211 are precision milled using the first bar cutter 13. After the end face of the top 21 is precision milled, the blank thin-walled hanging ring 2 is flipped so that its bottom 22 faces upward, and then the second fixing member is installed. The end face of the bottom 22 includes a top surface S222, a bottom surface S223, and an outer surface S221. After adjusting the L-shaped side milling head 33, the top surface S222, bottom surface S223, and outer surface S221 are precision milled using the first bar cutter 13.

[0038] It should be noted that in this invention, rough milling refers to leaving a margin after processing the product surface, while finish milling refers to processing the product surface to fully meet the process requirements. For example, if the required wall thickness is 5mm, the wall thickness after rough milling is 8mm, while the wall thickness after finish milling is 5mm, but there may be an error of ±0.5mm.
