Problems solved by technology
In mechanical drilling, the depth of the countersinking can be controlled by adjusting the stopper on the machine tool. However, in manual drilling, since there is no corresponding positioning device, the depth is completely controlled by the hand, so the depth of drilling and countersinking cannot be adjusted. Control, which affects the quality of the processed parts after subsequent production and assembly

Embodiment Construction
[0024] In order to deepen the understanding of the present invention, the present invention will be further described below in conjunction with the embodiments and accompanying drawings. The embodiments are only used to explain the present invention and do not constitute a limitation to the protection scope of the present invention.
[0025] Such as Figure 1-3 As shown, an adjustable positioning hexagonal shank drill includes a drill bit 1, the straight part of the drill bit 1 is embedded in the center hole of the countersink drill 3, and the stem of the countersink drill 3 is connected successively from right to left. There are a circlip 9, an adjusting sleeve 5 and a limit ring 10, the circlip 9 is clamped on the stem of the countersink 3 through a slot, the adjusting sleeve 5 can slide on the stem of the countersink 3, When the adjustment sleeve 5 moves to the rightmost end, the right end of the adjustment sleeve 5 abuts against the side of the circlip 9, and when the adju...

The invention discloses an adjustable positioning hexagonal handle drill. The adjustable positioning hexagonal handle drill comprises a drill bit; a straight rod part of the drill bit is embedded in acenter hole of a counter bit; a rod part of the counter bit is connected with a snap spring, an adjusting sleeve and a limiting ring in sequence; the adjusting sleeve can slide on the rod part of thecounter bit; when the adjusting sleeve slides to the most right end, the right end of the adjusting sleeve butts against the side surface of the snap spring; when the adjusting sleeve moves to the most left end, the left end of the adjusting sleeve butts against the side surface of the limiting ring; a positioning sleeve is screwed on the outer wall of the adjusting sleeve through a thread; the screwing position of the positioning sleeve is adjusted to obtain a cutting depth of changing a reaming conical surface of the counter bit; the right end of the positioning sleeve is outwards opened ina horn shape to obtain a larger limiting contact surface; and the right end surface of the positioning sleeve is connected with an O-shaped sealing ring. The device not only can realize the drillingdepth positioning, but also can adjust the relative connecting length between the adjusting sleeve and the positioning sleeve to achieve the drilling depth adjustability and to protect the surfaces ofmachined workpieces.
Description
technical field [0001] The invention relates to an adjustable positioning hexagonal shank drill. Background technique [0002] In daily life and industrial production, the processing of countersink holes for countersinking screws is widely used. On the one hand, the countersinking can embed the head of the screw into the profile to ensure the appearance; on the other hand, the countersinking can ensure that the contact surface between the screw head and the profile is a horizontal plane, which can ensure that the screw is always vertical during the screwing process. Downwards, no offset phenomenon occurs. [0003] In order to simplify the processing flow and shorten the processing time, the integrated drill-sink compound tool has been widely used. Common drilling processes are divided into two types: manual drilling and mechanical drilling. In mechanical drilling, the depth of the countersinking can be controlled by adjusting the stopper on the machine tool. However, in m...
