Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0029] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention as claimed, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are intended to fall within the scope of protection of the present invention.

[0030] Example

[0031] like Figures 1-8 As shown, a groove forming device for a thin-walled toothed part includes a pressure claw assembly 6, a support plate 2, an inner forming assembly 5 and an outer forming assembly 4. The thin-walled toothed part 1 is installed on the support plate 2, and the inner forming assembly 5 and the outer forming assembly 4 are respectively arranged at the inner and outer ends of the thin-walled toothed part 1. The pressure claw assembly 6 is arranged above the thin-walled toothed part 1 to support the thin-walled toothed part 1 to prevent the thin-walled toothed part 1 from rotating. The inner forming assembly 5 and the outer forming assembly 4 move relative to each other, and a groove 102 is die-cast on the thin-walled toothed part 1. The thin-walled toothed part 1 and the groove 102 are made by different processing methods. The thin-walled toothed part 1 is directly processed by a CNC machine tool, and then the groove 102 is die-cast by a forming device, which not only ensures the production quality but also greatly reduces the production time of the thin-walled toothed part 1, thereby improving the efficiency of the entire production.

[0032] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 8 As shown, an arc-shaped limit block 3 is provided on the support plate 2, and an empty groove 31 is provided on the limit block 3. The thin-walled toothed part 1 is arranged in the limit block 3. When the thin-walled toothed part 1 is connected in the limit block 3, the tooth top of the thin-walled toothed part 1 fits against the inner wall of the limit block 3, and the limit block 3 has a positioning effect on the thin-walled toothed part 1, so that the thin-walled toothed part 1 can only rotate with the center of the limit block 3 as the axis point, preventing the thin-walled toothed part 1 from sliding on the surface of the finished plate during processing. Several outwardly protruding toothed structures 101 are evenly distributed on the circumference of the thin-walled toothed part 1, and the processing position of the thin-walled toothed part 1 is the empty groove 31 position, that is, one of the tooth structures 101 on the thin-walled toothed part 1 is in the empty groove 31.

[0033] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 8 As shown, a bracket 22 is provided on the support plate 2, and the bracket 22 is provided at a position opposite to the center of the limit block 3. The pressure claw assembly 6 is provided on the bracket 22, and the pressure claw assembly 6 and the thin-walled toothed part 1 are aligned. The pressure claw assembly 6 includes a claw plate 62 and a rotating part 61. The claw plate 62 is provided with a number of telescopic claws that can move toward the direction of the thin-walled toothed part 1. The rotating part 61 is connected to the bracket 22. The claw plate 62 is provided at one end of the rotating part 61. The rotating part 61 can drive the claw plate 62 to rotate. The rotating part 61 adopts a rotating motor, and can also be other structures that can drive the claw plate 62 to rotate. Several groups of telescopic claws are distributed in an arc shape at the lower end of the claw plate 62. There is a large gap between the first telescopic claw and the last telescopic claw, which corresponds to the empty slot 31 of the limit block 3. The distribution shape of the telescopic claws is consistent with the shape of the limit block 3.

[0034] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 8 As shown, the telescopic claw includes a telescopic member 63 and a claw head 64. The telescopic member 63 drives the claw head 64 to rise and fall above the thin-walled toothed member 1. The telescopic member 63 is a telescopic cylinder. The claw head 64 is connected to the shaft end of the cylinder. When the shaft end of the cylinder extends out of the cylinder body, the claw head 64 is driven to descend. When the shaft end of the cylinder extends into the cylinder body, the claw head 64 is driven to rise. The adjacent claw heads 64 are roughly V-shaped slotted structures. The shape of the claw head 64 is the same as the shape of the interval between adjacent toothed structures 101. The claw head 64 is stepped as a whole. The claw head 64 has a ladder-like structure, and the ends of the claw heads 64 can extend into the grooves on both sides of the toothed structure 101. The head end of the claw head 64 is a protruding structure, and the diameter of the end of the claw head 64 is smaller than the diameter of the head end. When the telescopic member 63 drives the claw head 64 to descend and connect with the thin-walled toothed part 1, the head end of the claw head 64 is supported on the upper surface of the thin-walled toothed part 1, and the ends of the claw heads 64 extend into the thin-walled toothed part 1. This structure can prevent the claw head 64 from extending into the thin-walled toothed part 1 as a whole, and can accurately position the thin-walled toothed part 1 and firmly press and fix it.

[0035] When the thin-walled toothed part 1 is placed in the limit block 3, the telescopic part 63 drives the claw head 64 to descend, so that the claw head 64 is stuck in the thin-walled toothed part 1. At this time, the thin-walled toothed part 1 cannot rotate in the limit block 3, and the rotating part 61 is driven to work. The rotating part 61 drives the claw plate 62 to rotate, and the claw head 64 causes the thin-walled toothed part 1 to rotate.

[0036] like Figure 1 、 Figure 2 、 Figure 5 、 Figure 6 、 Figure 7As shown, the outer forming component 4 includes a U-shaped outer forming block 41 and a driving member I42. The outer forming component 4 is arranged at the upper end of the support plate 2, and the outer forming component 4 is aligned with the empty groove 31. The outer forming component 4 is slidably arranged at one end of the thin-walled toothed part 1. The driving member I42 is a telescopic cylinder, and other structures that can drive the outer forming block 41 to slide can also be used. The outer forming block 41 is connected to one end of the driving member I42, that is, the outer forming block 41 is connected to the axial end of the driving member I42. When the axial end of the driving member I42 is extended, it drives the outer forming block 41 to move synchronously toward the thin-walled toothed part 1. When the axial end of the driving member I42 is retracted, it drives the outer forming block 41 to move synchronously toward the driving member I42. The outer forming block 41 is aligned with the tooth structure 101 on the thin-walled toothed part 1. When the outer forming block 41 slides and is connected to the thin-walled toothed part 1, the middle part of the outer forming block 41 is clamped with the tooth structure 101, and the front end of the outer forming block 41 is clamped between adjacent tooth structures 101. A pressure block 411 is protruding from the outer forming block 41, and the pressure block 411 has the same shape as the outer forming block 41.

[0037] like Figures 1-8 As shown, a through hole 21 is provided on the support plate 2, a limit block 3 is provided on the outside of the through hole 21, and the limit block 3 and the through hole 21 are concentrically arranged, the thin-walled toothed part 1 and the through hole 21 are concentrically arranged, and the inner forming component 5 is provided at the lower end of the support plate 2, and the inner forming component 5 includes an inner forming block 51, a limit rod 53 and a driving member II 54, the inner forming block 51 extends into the through hole 21, and the inner forming block 51 is slidably connected to the inside of the thin-walled toothed part 1, and the driving member II 54 is also a telescopic cylinder structure, and can also be other structures that can drive the inner forming block 51 to slide. The lower end of the support plate 2 is provided with a support block 23, and the support block 23 is provided at the outer forming component 4 The lower end is aligned with the inner forming component 5, and a slide groove 231 is provided on the support block 23. The lower end of the outer forming block 41 passes through the support plate 2 and extends into the slide groove 231, and at the right end position of the slide groove 231, a limit rod 53 is set at one end of the inner forming block 51, and the limit rod 53 extends into the slide groove 231, and at the left end position of the slide groove 231, when the outer forming block 41 slides, the outer forming block 41 can only move along the direction of the slide groove 231, and when the inner forming block 51 slides, the inner forming block 51 can only move along the direction of the slide groove 231. The support block 23 limits the movement direction of the outer forming block 41 and the inner forming block 51, making their movement process more stable.

[0038] like Figures 1-8As shown, the inner forming block 51 and the tooth structure 101 of the thin-walled toothed part 1 have the same shape, and the inner forming block 51 is arranged in a W shape, and the middle section of the inner forming block 51 is protruding. When the inner forming block 51 and the thin-walled toothed part 1 are connected, the middle part of the inner forming block 51 is clamped at the position of the tooth structure 101 inside the thin-walled toothed part 1, and the two sides of the inner forming block 51 are respectively attached to the two sides of the tooth structure 101. A groove 52 is provided on the inner forming block 51, and the shape of the groove 52 is consistent with the shape of the inner forming block 51. The inner forming component 5 and the outer forming component 4 are arranged on the same straight line. When one of the tooth structures 101 of the thin-walled toothed part 1 is aligned with the outer forming block 41, the outer forming block 41 and the inner forming block 51 move in relative directions, and the pressing block 411 extends into the groove 52, so that a groove 102 is pressed out on the thin-walled toothed part 1. In this method, the processing of the thin-walled toothed part 1 and the processing of the groove 102 are separated. The structure of the thin-walled toothed part 1 is simple and the processing time is short. The CNC machine tool can first process the thin-walled toothed part 1 and then die-cast the groove 102 through the groove forming device, which greatly reduces the overall processing time of the thin-walled toothed part 1 while ensuring the processing accuracy of the groove 102.

[0039] Working principle: first put the processed thin-walled toothed part 1 into the limit block 3, so that one of the tooth structures 101 of the thin-walled toothed part 1 is at the position of the empty slot 31, drive the telescopic part 63 to work, and the shaft of the telescopic part 63 extends to drive the claw head 64 to move toward the thin-walled toothed part 1. Several claw heads 64 are clamped with the thin-walled toothed part 1, so that the position of the thin-walled toothed part 1 is fixed. At this time, the outside of the toothed structure 101 is facing the outer forming block 41, and the inside of the toothed structure 101 is facing the inner forming block 51, so that the driving part I 42 works, and the shaft of the driving part I 42 extends to drive the outer forming block 41 to move along the direction of the slide groove 231 toward the toothed structure 101, so that the driving part II 54 works, and the shaft of the driving part II 54 extends to drive the inner forming block 51 to move along the direction of the slide groove 231 toward the toothed structure 101. The outer forming block 41 and the inner forming block 51 squeeze the toothed structure 101, so that the pressing block 41 1 is extended into the groove 52, and the shape of the groove 102 is die-casted on the tooth structure 101. At this time, the groove 102 on the single tooth structure 101 is completed, and then the driving member I 42 is reset, the shaft of the driving member I 42 is retracted, and the outer forming block 41 is reset, so that the driving member II 54 is also reset, and the shaft of the driving member II 54 is retracted, and the inner forming block 51 is reset, so that the rotating member 61 drives the claw plate 62 to rotate, and the plurality of claw heads 64 make the thin-walled toothed member 1 rotate synchronously, so that the unprocessed toothed structure 101 is in the position of the empty groove 31, and the telescopic member 63 is driven to reset, and the shaft of the telescopic member 63 is retracted so that the claw head 64 and the thin-walled toothed member 1 are separated, so that the rotating member 61 is reset, and the rotating member 61 resets the claw plate 62, and then the telescopic member 63 is driven to work so that the claw head 64 is reconnected with the thin-walled toothed member 1 to fix it, and the above operation can be repeated to process the groove 102 on the thin-walled toothed member 1.
