Detailed description of the invention
As shown in Figure 1, Double-side rounding cutter described in the utility model, comprise handle of a knife 1, knife bar 2 and drill bit 3, knife bar 2 and drill bit 3 are structure as a whole, handle of a knife 1 is provided with deep hole 4 vertically, deep hole 4 diameter and knife bar 2 diameter match, handle of a knife 1 radial direction is provided with through hole 5, screw thread is provided with in through hole 5, through hole 5 is communicated with deep hole 4, handle of a knife 1 lower end is round table-like, drill bit 3 comprises top chamfered section 6 and below chamfered section 7, top chamfered section 6 is in round table-like, below chamfered section 7 is coniform in what stand upside down, top chamfered section 6 and below chamfered section 7 are equipped with chamfering cutting edge, the maximum gauge of top chamfered section 6 is identical with the maximum gauge of below chamfered section 7, the minimum diameter of top chamfered section 6 is identical with knife bar 2 diameter, knife bar 2 surface is provided with scale, knife bar 2 upper end penetrates in deep hole 4, through hole 5 both sides are provided with bolt, bolt penetrates handle of a knife 1 and fixes knife bar 2 with threaded engagement.
In the present embodiment, knife bar 2 side is provided with straight sword 10, can to the sidewall of product along carrying out chamfering, deburring; Below chamfered section 7 lower end of drill bit 3 is set to plane, can avoid causing accidental injury to product surface; The top chamfered section 6 of drill bit 3 and the chamfering cutting edge gradient of below chamfered section 7 are all set to 45 °, can meet multiple chamfer angle requirement fast in process.
During utility model works, handle of a knife 1 is arranged on the clamped one time tool of numerical control machine tool, cutter is according to setting orbiting motion, as shown in Figure 2, when needing the upper surface edge of converted products, the below chamfered section 7 of drill bit 3 is moved to product upper surface side, utilizes chamfered cutting edge 9 to carry out chamfering, deburring work; As shown in Figure 3, when needing the lower surface edge of converted products, for the product of different-thickness, first can loosen the bolt of through hole 5 side, regulate knife bar 2 length between handle of a knife 1 and drill bit 3 with reference to the scale on knife bar 2, make product sidewall be in the empty avoiding district of knife bar 2, effectively prevent sidewall damage, then tight a bolt fixing knife bar 2, and the top chamfered section 6 of drill bit 3 is moved to product lower surface side, utilizes chamfered cutting edge 8 to carry out chamfering, deburring work; As shown in Figure 4, when need the sidewall of converted products along time, first knife bar 2 length between handle of a knife 1 and drill bit 3 is regulated according to above-mentioned steps, ensure that the top chamfered section 6 of drill bit 3 does not contact with product lower surface, then knife bar 2 is moved to product side-walls, utilize straight sword 10 oppose side wall to carry out chamfering, deburring work.The utility model structure is simple, convenient mounting and clamping, flat edge on product can be completed along the chamfering on, lower plane edge and sidewall edge, deburring work on numerical control machine tool, avoid the manual operation that the later stage wastes time and energy, while increasing work efficiency, reduce cost of labor.
