Problems solved by technology

[0005] The purpose of this invention is to provide a split-type chamfering sleeve, assembly method, and chamfering drill bit. The technical problem to be solved is: if the matching gap between the inner diameter of the chamfering ring and the drill rod is too large, the working surface will jump greatly, and the Causes chipping of the inner chamfer in the hole; if the matching gap between the inner diameter of the chamfer ring and the outer diameter of the drill bit is too small, it will cause difficulty in assembly, and it will be difficult to implement when the chamfer ring needs to be adjusted

Embodiment Construction

[0047] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0048] Such as figure 1 with Image 6 As shown, the split-type chamfering sleeve includes two or more arc-shaped chamfering pieces 1.1.1 and a clamping ring 1.2, and two or more arc-shaped chamfering pieces 1.1.1 An annular chamfering ring 1.1 is formed; the chamfering ring 1.1 is set on the drill pipe 2.2, the clamping ring 1.2 is set on the chamfering ring 1.1, and the chamfering ring 1.1 is fastened to the above the drill pipe 2.2.

[0049] The clamping ring 1.2 is set on the chamfering ring 1.1, and the chamfering ring 1.1 composed of two or more chamfering pieces 1.1.1 is fastened on the drill pipe 2.2, so that the split chamfering set can be assembled and adjusted smoothly. Simple and easy to implement, the f...

Abstract

The invention relates to a spliced chamfering cover, an assembly method and a chamfering drill bit. The spliced chamfering cover comprises two or more circular-arc-shaped chamfering pieces and a hoop,and the circular-arc-shaped chamfering pieces form an annular chamfering ring; and a drill stem is sleeved with the chamfering ring, the chamfering ring is sleeved with the hoop, and the chamfering ring is fastened on the drill stem. Compared with the prior art, the spliced chamfering cover is easy to assemble and adjust, the fit clearance between the chamfering ring and the drill stem can be reduced through the fastening function of the hoop, runout of a working surface is reduced, and it is ensured that an inner chamfer of a machined glass hole is accurate in shape and free of edge breakage.

Description

technical field [0001] The invention relates to the technical field of glass processing, in particular to a split-type chamfering sleeve, an assembly method, and a chamfering drill bit. Background technique [0002] Glass holes are generally drilled with a diamond drill bit, and chamfered with a chamfering sleeve. The prior art method: a combined diamond chamfering drill bit is used, the chamfering sleeve is fitted on the outer wall of the drill bit working ring, and the drilling and chamfering at both ends of the glass are completed at one time by using a pairing method. This method has the following problems: First, the inner diameter of the chamfering ring is larger than the outer diameter of the drill bit, which inevitably forms a certain amount of clearance with the drill bit, and the working surface of the chamfering sleeve assembled on the drill bit cannot ensure coaxiality and runout requirements with the drill bit. The occurrence of eccentric work causes chipping a...
