DETAILED DESCRIPTION

[0028] like Figures 1 to 9 As shown, a bevel nut processing tool of the present invention includes a nut conveying track 1, a feeding component 2, a material dividing component 3, a bevel milling component 4, a drilling component 5, a bevel hole chamfering component 6, a tapping component 7, a lower chamfering component 8 and a material shifting component 9 which are sequentially arranged from the front end to the rear end of the nut conveying track 1, and the nut conveying track 1 is installed on the processing platform, and the nut conveying track 1 is arranged horizontally, with the extension direction of the nut conveying track 1 as the longitudinal direction, and the blank of the bevel nut 10 passes through the above-mentioned equipment in sequence, and the blank is subjected to the processing processes of feeding, dividing, bevel milling, drilling, hole chamfering and tapping respectively to form a finished product. Of course, correspondingly, a proximity switch is installed on each station, so that the process can be carried out effectively.

[0029] The feeding assembly 2 of the present invention adopts existing equipment and is used to convey the blank of the nut to the dividing assembly 3 through the action of the vibrating plate. The feeding assembly 2 conveys the blank of the bevel nut 10 to the nut conveying track 1 after the dividing assembly 3 divides the material, and performs machining operations on the nut conveying track 1. The bevel milling assembly 4 is used to machine the bevel of the bevel nut 10, and the bevel of the bevel nut 10 of the present invention deviates from the conveying direction of the nut. The drilling assembly 5 is used to drill the bevel nut 10 from bottom to top, avoiding the slipping problem caused by the contact between the drill bit and the bevel when drilling from top to bottom, and can effectively improve the processing efficiency.

[0030] The chamfering assembly 6 of the present invention is used to chamfer the upper opening of the hole, the tapping assembly 7 is used to tap the chamfered nut 10, and the lower chamfering assembly 8 is used to chamfer the lower opening of the hole. The chamfering assembly 6 can be adapted to the chamfering according to the inclination of the inclined surface, and the uniformity of the chamfering angle can be ensured. The material shifting assembly 9 is used to push each group of chamfered nuts 10 on the nut conveying track 1, so that each group of chamfered nuts 10 can be moved along the nut conveying track 1 to the processing position of each processing assembly, which can ensure the continuity of processing and effectively improve the efficiency of processing.

[0031] In this embodiment, the bevel hole chamfering assembly 6 includes a first support 11, a first telescopic device 12, a first slide 13, a first mounting plate 14, a first motor 15, a swash plate 16, a column sleeve 17, a compression column 18, a piston column 19, a spring 20, a chamfering rod 21, a rotating body 22 and a rotating support frame. The first support 11 is fixed on the processing platform, and the first support 11 is located on one side of the nut conveying track 1. The first slide 13 is vertically slidably installed on the first support 11, and the slide can slide vertically. The first telescopic device 12 is fixed at the upper end of the first support 11, and the output end of the first telescopic device 12 is connected to the first slide 13. The first slide 13 provides power for moving up and down through the first telescopic device 12.

[0032] Furthermore, a first mounting plate 14 is fixed on the first slide seat 13, and the first mounting plate 14 is parallel to the horizontal direction. The first motor 15 is mounted on the first mounting plate 14; the output end of the first motor 15 is vertical and connected to the swash plate 16, and a plurality of column sleeves 17 are evenly mounted on the lower surface of the swash plate 16 along the circumferential direction. The column sleeve 17 is hinged to one end of a compression column 18, and the other end of the compression column 18 is slidingly sealed in a through hole opened in a rotating body 22. The rotating body 22 is rotatably connected to the first mounting plate 14 through a rotating support frame, and the other end of the through hole is slidably connected to a piston column 19. The compression column 18 and the piston column 19 are connected by a spring 20, and the cavity separated by the compression column 18 and the piston column 19 is filled with hydraulic oil. The piston column 19 is fixedly connected to a chamfered rod 21, and the lower end of each chamfered rod 21 is in a plane parallel to the inclined surface of the bevel nut 10. When the first motor 15 is started, the first motor 15 can drive the swash plate 16 to rotate, so that the column sleeve 17 drives the compression column 18 to rotate around the center line of the rotating body 22. When the compression column 18 rotates, due to the change of the axis, the compression column 18 can continuously compress the cavity between the compression column 18 and the piston column 19. The spring 20 provides recovery and limiting functions, so that the compression column 18 can drive the piston column 19 to move through the hydraulic oil, and the piston column 19 can drive the chamfering rod 21 to move, so that the lower end of each chamfering rod 21 can always be guaranteed to be parallel to the inclined surface of the bevel nut 10, and the length of each chamfering rod 21 extending into the hole when the axis moves is consistent, thereby ensuring the accuracy of the chamfering processing.

[0033] The present invention uses hydraulic oil to link the compression column 18 and the piston column 19, which can effectively ensure the flexibility of the chamfered rod 21 during axial movement and reduce damage to the bevel nut 10 during movement.

[0034] In this embodiment, the rotating support frame includes an inner rotating ring 23, an outer rotating ring 24, a supporting ring 25, a support rod 26 and a suspension rod 27. The inner rotating ring 23 is coaxially fixed to the outside of the rotating body 22, the outer rotating ring 24 is rotatably matched with the inner rotating ring 23, the outer rotating ring 24 is connected to the supporting ring 25 through the support rod 26, one end of the suspension rod 27 is fixedly connected to the supporting ring 25, and the other end of the suspension rod 27 is vertically fixedly connected to the first mounting plate 14. By setting the above manner, it can be effectively used to support the rotating body 22 to ensure that the rotating body 22 can rotate smoothly.

[0035] In this embodiment, a number of abrasive particles for chamfering are installed on the outer surface of the chamfering rod 21, which can facilitate the chamfering rod 21 to chamfer the upper opening of the hole. The lower end of the chamfering rod 21 forms a rounded corner, which facilitates the chamfering rod 21 to penetrate into the hole of the bevel nut 10 and reduce damage to the bevel nut 10.

[0036] In this embodiment, the processing tooling also includes a nut limiting assembly 28, which is installed on the side of the nut conveying track 1 corresponding to the bevel hole chamfering assembly 6. The nut limiting assembly 28 includes a limiting clamp 29, a second telescopic device 30 and a second support 31. The second support 31 is fixed on the side of the nut conveying track 1, and the second telescopic device 30 is installed on the second support 31. The output end of the second telescopic device 30 is connected to the limiting clamp 29, and the outer end of the limiting clamp 29 forms a limiting groove 32 for limiting the bevel nut 10. By setting the nut limiting assembly 28, the front and rear sides of the bevel nut 10 can be limited when the bevel nut 10 is chamfered, which reduces the shaking of the nut and ensures the processing accuracy. The blank of the nut is hexagonal as a whole. Since the conveying channel of the nut conveying track 1 can limit the bevel nut 10 in the horizontal and vertical directions, the nut limiting assembly 28 can limit the bevel nut 10 in the longitudinal direction, which effectively ensures the stability of the bevel nut 10 during processing.

[0037] In this embodiment, the material distribution assembly 3 includes a guide rail 33, a third support 34, a third telescopic device 35, a longitudinal push plate 36, a fourth support 37, a fourth telescopic device 38 and a transverse push plate 39. The guide rail 33 is connected to the processing platform through the third support 34, the guide rail 33 is connected to the output end of the feeding assembly 2, the third telescopic device 35 is fixed to the side of the guide rail 33, and the third telescopic device 35 is connected to the longitudinal push plate 36. The fourth telescopic device 38 is connected to the processing platform through the fourth support 37, and the output end of the fourth telescopic device 38 is connected to the transverse push plate 39. The transverse push plate 39 pushes the bevel nut 10 at the end of the guide rail 33 to the entrance of the nut conveying track 1 in the transverse direction, and the longitudinal push plate 36 pushes the bevel nut 10 to the nut conveying track 1 in the longitudinal direction. After the blank on the feeding assembly 2 enters the end of the guide track 33, it can be limited by the entrance end of the nut conveying track 1. At this time, the transverse push plate 39 is started to push the bevel nut 10 at the end of the guide track 33 horizontally to the entrance of the nut conveying track 1, and then the bevel nut 10 is pushed longitudinally to the nut conveying track 1 by the longitudinal push plate 36. The bevel nut 10 can be divided, which effectively ensures that each group of bevel nuts 10 is processed in an orderly and spaced manner.

[0038] In this embodiment, the bevel milling assembly 4 includes a fifth support 40, a fifth telescopic device 41 fixed on the fifth support 40, and a second motor 42 connected to the output end of the fifth telescopic device 41. The output end of the second motor 42 is connected to the milling disc 43 through a coupling. The plane of the milling disc 43 is parallel to the bevel of the bevel nut 10, which is convenient for processing the bevel of the bevel nut 10.

[0039] In this embodiment, the material-digging assembly 9 includes a sixth support 44, a sixth telescopic device 45 is installed on the sixth support 44, the output end of the sixth telescopic device 45 is connected to a bracket 46, a seventh telescopic device 47 is installed on the bracket 46, the output end of the seventh telescopic device 47 is vertically connected to a support plate 48, a plurality of material-digging plates 49 are evenly installed on the upper side of the support plate 48, and a material-digging groove corresponding to the material-digging plates 49 is formed on the lower side of the nut conveying track 1. When the sixth telescopic device 45 is extended and retracted, each material-digging plate 49 can be controlled to push the bevel nut 10 in the longitudinal direction, so that the bevel nut 10 can smoothly enter the next station.
