Detailed Description

In order to make the technical means, creation characteristics, achievement purpose and efficacy of the utility model easy to understand and understand, the utility model is further clarified by combining the specific drawings.

It should be noted that, in the present invention, when an element is referred to as being "fixed" to another element, it may be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only and do not denote a unique embodiment.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

Combine fig. 1, 2 to show, the utility model provides a drilling assembly, drilling assembly include with the 1 fixed connection's of main shaft that provides power components of a whole that can function independently drill bushing 10, the one end that main shaft 1 was kept away from to components of a whole that can function independently drill bushing 10 supplies drill bit 20 to plant for the straight hole, and is equipped with lock nut 30 on the components of a whole that can function independently drill bushing 10 of planting drill bit 20 one end be used for with drill bit 20 with components of a whole that can function independently drill bushing 10 locking fixed.

Through the drilling assembly provided by the utility model, one end of the split drill bushing 10 is fixed on the main shaft 1 for providing power, and one end far away from the main shaft 1 is provided with a straight hole for inserting the drill bit 20, and after the drill bit 20 is inserted, the split drill bushing 10 is screwed and fixed through the locking nut 30; that is to say, the drill bit 20 adopts a straight hole engagement and locking and fixing mode of the locking nut 30, compared with the traditional taper hole engagement mode, when the drill bit 20 is replaced, the split drill bushing 10 is not required to be detached from the main shaft 1, the locking nut 30 can be loosened, and the drill bit 20 can be easily taken out; the drill bit 20 to be replaced is reinserted into the split drill sleeve 10, and the locking nut 30 is tightened again. The technical scheme greatly improves the replacement efficiency of the drill bit 20. Meanwhile, as the split drill bushing 10 is not disassembled, and the drill bit 20 adopts the mode of straight hole occlusion and locking and fixing of the locking nut 30, the problem of low concentricity caused by occlusion of a taper hole is avoided, so that the problem of jumping of the drill bit 20 during high-speed rotation is avoided, and the service lives of the drill bit 20 and the split drill bushing 10 are prolonged.

Further, according to the utility model discloses, components of a whole that can function independently drill bushing 10 is kept away from be equipped with a plurality of indents portions 11 on the one end lateral wall of main shaft 1, indent portions 11 extend to the tip that main shaft 1 was kept away from to components of a whole that can function independently drill bushing 10. Through the setting of this indent portion 11, the locking drill bit 20 that can be fast, stable when screwing up lock nut 30 is convenient.

In a specific embodiment of the present invention, as shown in fig. 2, the indentations 11 are circumferentially spaced along the side wall of the split drill bushing 10.

Preferably, the indentation 11 is a strip, and four indentations are uniformly arranged along the circumferential direction of the sidewall of the split drill bushing 10 at intervals.

In a specific embodiment of the present invention, the indentation 11 is spirally arranged along the circumference of the side wall of the split drill sleeve 10. The helically arranged indentations 11 also provide a pre-tightening force during screwing of the locking nut 30, so that the drill bit 20 is well fixed to the split drill bushing 10.

The utility model also provides a glass puncher, the glass puncher adopt above-mentioned drilling subassembly. When the drilling assembly is used for drilling glass, the replacement efficiency of the drill bit can be obviously improved, so that the glass drilling efficiency is improved; simultaneously, because this drilling subassembly has improved the concentricity to higher accuracy when can ensure glass punches.
