Description
Technical Field
The utility model relates to a low-cost high-efficiency large-aperture chamfering device, and belongs to the technical field of flange production equipment.
Background
The flange is a part for connecting the shafts and is also used for connecting the pipe ends; there are also flanges used on the device access ports for connection between two devices. The connection of the flanges is realized by connecting the two flanges together by bolts through the bolt holes arranged on the flange ring. In the flange production process, since a plurality of bolt holes are formed around the flange, each bolt hole also needs to be chamfered.
At present, for the bolt holes with small and medium diameters of the small and medium-sized flanges, a special conical chamfering drill is generally adopted to chamfer the bolt holes; as for the large-aperture bolt holes of the large flange, due to the fact that corresponding large chamfering drill bits and large drilling machines are not available, chamfering is generally achieved by manually polishing the large-aperture flange one by adopting an electric hand drill, time and labor are wasted, chamfering efficiency is low, potential safety hazards still exist, and machining cost is high.
Therefore, a new approach to large bore bolt hole chamfering is needed.
Disclosure of Invention
The utility model aims to overcome the defects and provide the large-aperture chamfering device which is simple in structure, high in chamfering processing efficiency, low in cost and high in safety.
The purpose of the utility model is realized in the following way:
the low-cost high-efficiency large-aperture chamfering device comprises an annular base sleeved on a drill bit, wherein an annular inclined plane is arranged at the bottom of the base, a shaped groove is formed in the annular inclined plane, and a cutting tool bit is fixedly arranged in the shaped groove; the cutting edge surface of the cutting tool bit is higher than the groove.
Further, the chamfering device is fixedly sleeved at the root of the drill bit cutting section through a bolt.
Further, the cutting bit is secured within the slot by welding or bolting.
Further, the cross-sectional shape of the profile groove matches the profile of the cutting bit.
Further, the cutting tool bit is a high-speed steel tool bit or a ceramic tool bit.
Compared with the prior art, the utility model has the beneficial effects that:
the chamfering device is simple in structure, the annular base arranged at the root of the drill bit synchronously rotates at a high speed along with the drill bit, the cutting tool bit arranged on the base rotates at a high speed along with the base to chamfer and cut the bolt hole, chamfering operation can be completed while the bolt hole is drilled, additional flange carrying, repeated clamping and other working procedures are omitted, a large-scale processing machine tool is not required, manual chamfering is not required, chamfering processing cost is low, chamfering working efficiency of large-scale flange large-aperture bolt holes is greatly improved, and safety is good.

Detailed Description
Referring to fig. 1-2, the utility model relates to a low-cost high-efficiency large-aperture chamfering device:
example 1: the chamfering device comprises an annular base 2 fixedly sleeved at the root of the cutting section of the drill bit 1 through bolts 6, and the bolts 6 are symmetrically arranged on the side surface of the base 2 in a rotating mode; the bottom of the base 2 is provided with an annular inclined plane 3, the annular inclined plane 3 is provided with a groove 4, a cutting tool bit 5 is fixedly arranged in the groove 4 through copper welding, and the cutting tool bit 5 is a high-speed steel tool bit; the cutting tool bit 5 is positioned at a spiral depression between spiral cutting edges of the drill bit 1, and the cutting edge surface of the cutting tool bit 5 is higher than the groove 4; the cross section shape of the groove 4 is matched with the shape of the cutting tool bit 5, and the groove 4 provides support for the cutting tool bit 5 during chamfering cutting;
example 2: the groove 4 is internally provided with a bolt hole, the cutting tool bit 5 is fixedly arranged in the groove 4 through a bolt, the groove 4 provides cutting support for the cutting tool bit 5, the cutting tool bit 5 is a ceramic tool bit, and the rest part is consistent with the embodiment 1.
During working, a proper drill bit 1 and an annular base 2 are selected according to the diameters of the bolt holes; mounting a cutting tool bit 5, and fixedly mounting the cutting tool bit 5 in the groove 4, wherein if the cutting tool bit 5 is a high-speed steel tool bit, a copper welding mode is preferably adopted, and if the cutting tool bit 5 is a ceramic tool bit, a bolt screwing fixing mode is adopted; sleeving a base provided with a cutting bit 5 on the drill bit 1, rotating the cutting bit 5 towards the head direction of the drill bit 1, adjusting the position of the base 2 to ensure that the cutting bit 5 is positioned between spiral cutting edges of the drill bit 1, and fixing the base at the root of a cutting section of the drill bit 1 by using a bolt;
during drilling, the drill bit 1 drills the bolt hole first, then continues to drill downwards, so that the cutting tool bit 5 touches the corner of the bolt hole, the high-speed rotating cutting tool bit 5 cuts the corner of the bolt hole to form a chamfer, the drilling and the chamfer are finished synchronously, the chamfering operation is not required to be carried out separately, repeated flange clamping and flange carrying are avoided, even a large-scale processing machine tool is purchased, and the method has remarkable economic benefit for large-scale flange production.
In addition: it should be noted that the above embodiment is only one of the optimization schemes of this patent, and any modification or improvement made by those skilled in the art according to the above concepts is within the scope of this patent.
