[0035] To further understand the content of this invention, the invention will be described in detail with reference to the embodiments. It should be understood that the embodiments are merely illustrative and not limiting of the invention.

[0036] Example 1

[0037] like Figures 1-3 As shown, this embodiment provides a milling composite device for machining irregularly shaped thin-walled parts, which includes a device body 100. The device body 100 includes a main frame 110, a machining base 120 is provided at the main frame 110, and a workpiece 130 is provided at the machining base 120. A mounting ring 310 is formed at the machining base 120, and a plurality of external positioning mechanisms 320 for positioning the outer wall of the workpiece 130 are movably provided at the mounting ring 310. The workpiece 130 has a positioning cavity 131, and an internal positioning mechanism 330 is provided at the machining base 120 for penetrating into the positioning cavity 131 to achieve positioning of the inner wall of the workpiece 130.

[0038] This invention discloses a milling composite device for machining irregularly shaped thin-walled parts. By placing the workpiece 130 to be machined 120 into the machining base, and then using an outer positioning mechanism 320 and an inner positioning mechanism 330 to limit the workpiece 130 internally and externally, compared with the prior art, this application fixes the workpiece by means of internal and external limiting clamping. When fixing thin-walled parts, which are relatively easy to deform, it can ensure the stability of clamping and avoid excessive deformation of the workpiece itself.

[0039] Combination Figures 2-9 As shown, in this embodiment, a plurality of first mounting holes 410 are provided through the inner wall of the mounting ring 310. The outer positioning mechanism 320 includes a first column 420 slidably disposed in the first mounting hole 410. The outer end of the first column 420 is provided with a contact member 440 for pressing and fixing the outer wall of the workpiece 130 to be processed. A second column 430 is provided vertically on the outer wall of the first column 420 at the opposite end of the contact member 440. A third column 450 is provided at the bottom of the outer wall of the processing base 120. A spring 460 for pulling the contact member 440 is provided between the second column 430 and the third column 450. A fourth column 470 is provided at the outer end of the second column 430. A plurality of positioning holes 480 are provided through the outer wall of the fourth column 470 along the axial direction. A telescopic motor 510 is provided at the bottom of the inner wall of the main frame 110. A lifting plate 511 is provided at the driving end of the telescopic motor 510. A plurality of fifth columns 512 that penetrate into the positioning holes 480 are provided at equal intervals on the bottom of the outer wall of the lifting plate 511.

[0040] With the above structure, when the workpiece 130 is externally clamped, the third column 450 pulls the second column 430 to move through the spring 460, thereby causing the first column 420 to move toward the workpiece 130. The contact member 440 will fit into the different shapes of the outer wall of the workpiece 130, realizing the rapid pre-fixation of the outer wall of the workpiece 130. At the same time, after the device is pre-fixed, the telescopic motor 510 is started through the control panel, causing the lifting plate 511 to move upward. The fifth column 512 on the lifting plate 511 is inserted into the positioning hole 480, realizing the rapid fixation of the fourth column 470 with different extension lengths, improving the external fixing efficiency of the device.

[0041] Combination Figures 2-7 As shown, in this embodiment, the contact member 440 includes a connector 910 provided at the end of the outer wall of the first column 420. A concave groove 920 is provided at the upper part of the outer wall of the connector 910. A mating part 930 is slidably inserted into the concave groove 920. A connecting hole 940 is provided through the center of the upper part of the outer wall of the mating part 930. Multiple mating parts 930 are engaged and connected. A positioning bolt 950 is provided at the connecting hole 940 for fixing multiple mating parts 930 to each other.

[0042] With the above structure, when clamping and fixing the outside of the workpiece 130 of different thicknesses, the operator will engage the docking part 930 into the concave groove 920 and fix the docking part 930 and the concave groove 920 with bolts. According to the actual use, another docking part 930 will be engaged above the docking part 930 and the two will be spliced ​​and fixed with positioning bolts 950. This changes the height of contact with the outside of the workpiece 130 and improves the applicability of the device.

[0043] Combination Figures 2-7 As shown, in this embodiment, a plurality of second mounting holes 530 are provided through the outer wall of the processing base 120. A threaded post 610 located in the positioning cavity 131 is provided at the second mounting hole 530. A positioning handle 620 is provided at the lower middle part of the outer wall of the threaded post 610. A blocking member 630 for fitting tightly against the inner wall of the positioning cavity 131 is provided on the outer wall of the threaded post 610. The blocking member 630 includes an adjusting plate 710 provided in the positioning cavity 131. A through hole 720 for the threaded post 610 to slide and engage is provided at the adjusting plate 710. A limiting plate 730 with a diameter larger than the through hole 720 is formed at the top of the threaded post 610. A contact ring 740 for contacting the inner wall of the positioning cavity 131 is rotatably provided on the outer wall of the adjusting plate 710.

[0044] With the above structure, after the workpiece 130 is fixed externally, the stop 630 is placed into the pre-opened positioning cavity 131 on the workpiece 130, and the threaded post 610 is inserted into the second mounting hole 530. The stop 630 is fixed to the processing base 120 by the positioning handle 620, thereby achieving internal fixation of the workpiece 130. At the same time, when the workpiece 130 has multiple positioning cavities 131, the operator rotates the adjustment plate 710 so that the through hole 720 is connected to the second mounting hole 530. The adjustment plate 710 is threaded to the first splicing ring 750 and the second splicing ring 760, thereby facilitating the insertion of the threaded post 610 into the through hole 720 and the second mounting hole 530. The limiting plate 730 and the processing base 120 can jointly form the upper and lower limits of the adjustment plate 710.

[0045] Combination Figures 1-7As shown, in this embodiment, the contact ring 740 includes a first splicing ring 750 and a second splicing ring 760 respectively disposed in the upper and lower parts of the adjustment disc 710. An annular cavity 770 is formed on the opposite side of the first splicing ring 750 and the second splicing ring 760. An extension port 771 communicating with the outside is formed through the inner wall of the annular cavity 770. A pressing block 772 is slidably disposed in the extension port 771. The pressing block 772 has a first inclined block 773 that extends into the annular cavity 770. A connection port 780 for communicating with the annular cavity 770 is formed on the top of the outer wall of the first splicing ring 750. A second inclined block 790 is slidably disposed at the connection port 780. The second inclined block 790 is used to squeeze the first inclined block 773 so that the pressing block 772 is displaced.

[0046] With the above structure, the stop member 630 is placed into the positioning cavity 131. By pressing the clamping block 772, the clamping block 772 in the extension port 771 moves towards the inner wall of the positioning cavity 131, thereby fitting against the inner wall of the positioning cavity 131 and ensuring the stability of the positioning of the stop member 630 in positioning the workpiece 130. At the same time, the second inclined block 790 is placed into the connection port 780, and the second inclined block 790 is fixed to the second splicing ring 760 by bolts. During this process, the second inclined block 790 will press against the first inclined block 773, thereby pushing the clamping block 772 to both sides, thereby achieving the clamping between the clamping block 772 and the positioning cavity 131.

[0047] The present invention also provides a working method of a milling composite device for machining irregular thin-walled parts, comprising the following steps: S1: placing the workpiece 130 to be machined into the machining base 120;

[0048] S2: The external positioning mechanism 320 will automatically fit into the outer wall surface of the workpiece 130;

[0050] S4: Insert the inner positioning mechanism 330 into the positioning cavity 131 and connect it to the processing base 120.

[0051] With the above structure, the inner positioning mechanism 330 and the outer positioning mechanism 320 are used to achieve multi-directional positioning of the workpiece 130, ensuring the stability of the device in fixing the workpiece 130.
