Detailed Embodiments

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0020] To further understand the content of the present utility model, the present utility model will be described in detail in conjunction with the accompanying drawings.

[0021] Combined with Figures 1 - 4 , in this embodiment, a chamfering device for high-precision sheet metal parts processing includes a fixed platform 1. One end of the fixed platform 1 is fixedly connected to a support plate 11. The upper end of the support plate 11 is provided with a mounting plate 12 parallel to the fixed platform 1. One end of the mounting plate 12 away from the support plate 11 is movably connected to a chamfering assembly 2. One ends of the mounting plate 12 and the fixed platform 1 close to the chamfering assembly 2 are both semi-circular structures. The end of the fixed platform 1 close to the chamfering assembly 2 is provided with chamfering limit plates 13 with different diameters. The chamfering limit plates 13 support the sheet metal parts to be chamfered. The chamfering limit plates 13 are arranged on the circumference of the semi-circular structure. For chamfering limit plates 13 with different diameters, the chamfering assembly 2 includes a central support rod 21, a threaded rod 22, a moving pressure block 23, a synchronous pressure block 24, a synchronous plate 25 and a chamfering motor 26. The lower end of the central support rod 21 is movably connected to the threaded rod 22. One end of the threaded rod 22 is movably connected to the moving pressure block 23. When the threaded rod 22 rotates, the moving pressure block 23 will not move along with it. Both sides of the moving pressure block 23 are movably connected to the synchronous pressure block 24. The synchronous plate 25 is fixedly connected to the upper end of the central support rod 21. One end of the synchronous plate 25 is provided with a chamfering motor 26. When the central support rod 21 moves up and down or rotates, it can synchronously drive the threaded rod 22 and the synchronous plate 25 to move.

[0022] In this embodiment, a pressing cylinder 121 is arranged on the lower surface of the mounting plate 12. The pressing cylinder 121 drives the pressure block to move to play a large-range pressing and fixing role on the sheet metal parts to prevent the displacement of the sheet metal parts. An activity hole 122 is opened at the connection position between the mounting plate 12 and the central support rod 21. The activity hole 122 is sleeved with the central support rod 21. The central support rod 21 can rotate or move up and down in the activity hole 122. Bolt positioning holes 123 are distributed around the activity hole 122 on the mounting plate 12. The distribution positions of the bolt positioning holes 123 match the distribution positions of the chamfering limit plates 13. When one end of the synchronous plate 25 is fixed to the bolt positioning hole 123 by a bolt, the position of the synchronous plate 25 is fixed and the central support rod 21 cannot rotate.

[0023] In this embodiment, a positioning bolt meshing with the bolt positioning hole 123 is provided at one end of the synchronization plate 25 away from the chamfering motor 26. The synchronization plate 25 is fixed through the positioning bolt and the bolt positioning hole 123 to lock the position of the synchronization plate 25 and prevent the synchronization plate 25 from rotating.

[0024] In this embodiment, a threaded pipe 211 is penetrated and connected to the lower end of the central support rod 21. The threaded rod 22 penetrates the threaded pipe 211. Outer sleeve pipes 212 distributed in a V shape are arranged on both sides of the threaded pipe 211, and the inside of the outer sleeve pipe 212 is a hollow structure.

[0025] In this embodiment, a guide rod 231 penetrating the moving press block 23 is provided on the moving press block 23. The guide rod 231 is fixedly connected to the moving press block 23. The moving press block 23 moves under the push of the threaded rod 22, driving the guide rod 231 to displace synchronously.

[0026] In this embodiment, a retractable rod 241 in the same direction as the outer sleeve pipe 212 is provided on one side of the synchronization press block 24. The retractable rod 241 is sleeved with the outer sleeve pipe 212. A guide hole 242 matching the guide rod 231 is formed on the synchronization press block 24. When the moving press block 23 moves along the direction of the threaded rod 22, the guide rod 231 moves simultaneously, driving the synchronization press block 24 to displace. Under the restriction of the retractable rod 241, the synchronization press block 24 moves obliquely to increase or decrease the distance between the synchronization press blocks 24 to adapt to chamfers with different diameters. Under the combined action of the synchronization press block 24 and the moving press block 23, the chamfered part of the sheet metal part is pressed to prevent local deformation of the sheet metal part during chamfering.

[0027] In this embodiment, a rotating shaft 261 is provided at the output end of the chamfering motor 26. A vertically arranged electric telescopic rod 262 is connected to the lower end of the rotating shaft 261. A grinding machine 263 is provided at one end of the electric telescopic rod 262. The synchronization plate 25 controls the rotation direction of the chamfering motor 26, driving the chamfering motor 26, the moving press block 23, and the synchronization press block 24 to move to a suitable chamfering limit plate 13 to chamfer the sheet metal part.

[0028] Working process: The central support rod 21 is lifted as a whole, and the sheet metal part to be chamfered is placed on the chamfering limit plate 13 corresponding to the chamfering diameter. The pressing cylinder 121 drives the pressing block to move to fix the sheet metal part. Rotate the angle of the central support rod 21 so that the threaded rod 22 and the synchronous plate 25 both point to the chamfering limit plate 13, and adjust the positions of the moving pressing block 23 and the synchronous pressing block 24 according to the diameter of the chamfering limit plate 13. When adjusting, rotate the threaded rod 22, and the moving pressing block 23 drives the synchronous pressing block 24 to displace. The distance between the synchronous pressing blocks 24 is adjusted to be less than the diameter of the chamfering limit plate 13. Loosen the central support rod 21, and the central support rod 21 moves downward, and fix the position of the synchronous plate 25 through the positioning bolt. Press the chamfering position of the sheet metal part with the moving pressing block 23 and the synchronous pressing block 24. The electric telescopic rod 262 controls the grinding machine 263 to move to the chamfering edge of the sheet metal part, and drives the grinding machine 263 to rotate by the chamfering motor 26 to chamfer the sheet metal part.

[0029] In summary, for the chamfering device for high-precision sheet metal part processing of the present utility model, chamfering limit plates 13 with different diameters are provided, which can chamfer the sheet metal parts with different diameters. At the same time, a moving pressing block 23 and a synchronous pressing block 24 are arranged on the chamfering limit plate 13 to press the chamfering position, which can prevent local deformation of the sheet metal part during chamfering. Moreover, the central support rod 21 drives the threaded rod 22 and the synchronous plate 25 to move at the same time, and the pressing and chamfering positions are adjusted simultaneously, which is convenient for operation and can adapt to various chamfering specifications.
