Abstract
The utility model relates to the technical field of machining cutters, in particular to a twist drill. A drill handle is provided with an external thread and connected with a limiting device. The limiting device comprises a supporting part with a central hole and sliding parts detachably connected to the two side wall surfaces of the supporting part, and an internal thread matched with the external thread is arranged in the central hole. According to the twist drill, caution on drilling depth and stopping of excessively-deep drilling can be achieved.
Description
Technical field
The utility model relates to machining tool technical field, relates in particular to a kind of fluted drill.
Background technology
When bit bore, often there is the excessively dark situation of brill.This not only affects the precision of product, when serious, even causes product to produce the damage of irreparability.
Utility model content
The purpose of this utility model is to provide a kind of fluted drill that warning was holed deeply and can be played Intercepting effects that has.
Realize the technical solution of the utility model as follows: fluted drill, comprise spiral bit, and drillstock; Described drillstock is provided with external screw thread, and is connected with stopping means; Described stopping means comprises the support member that is provided with centre bore, and is detachably connected on the sliding part in support member two side walls; In described centre bore, be provided with the internal thread with external screw thread adaptation.
Described sliding part can adopt semicircle.
Described sliding part can adopt rectangle.
Described external thread length is greater than internal thread.
Described sliding part is provided with buffer part by the surface of drill bit side.
The beneficial effects of the utility model are: comprise the support member that is provided with centre bore by stopping means, and be detachably connected on the sliding part in support member two side walls; In described centre bore, be provided with and the internal thread of external screw thread adaptation, realize the spacing of the Twist Drill degree of depth and holed and play Intercepting effects when dark.Can adopt semicircle or rectangle by sliding part, play the obstruction degree that regulates.Be greater than internal thread by external thread length, can realize the fine setting of stopping means.Lean on the surface of drill bit side to be provided with buffer part by sliding part again, in the time that stopping means is encountered workpiece, reduce the friction to workpiece.
Brief description of the drawings
By the detailed description below in conjunction with accompanying drawing, the utility model is aforesaid will be become apparent with other object, feature and advantage.
Wherein: Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model A-A cutaway view;
In accompanying drawing, 1 is support member, and 2 is sliding part, and 3 is bolt, and 4 is external screw thread, and centered by 5 hole, and 6 is internal thread, and 7 is through hole, and 8 is blind hole, and 9 is buffer part, and 10 is drillstock, and 11 is drill bit.
Detailed description of the invention
Shown in Fig. 1-Fig. 2, comprise spiral bit 11, and drillstock 10; Described drillstock is provided with external screw thread 4, and is connected with stopping means; Described stopping means comprises the support member 1 that is provided with centre bore, and is detachably connected on the sliding part 2 in support member two side walls; In described centre bore, be provided with the internal thread 6 with external screw thread adaptation; By the sliding part 2 on stopping means, after fluted drill drill bit pierces object, sliding part will be stuck in aperture place, and realization is spacing to the Twist Drill degree of depth.
Shown in Fig. 1-Fig. 2, on described sliding part, be evenly equipped with through hole 7; Described support member and through hole corresponding position are provided with a blind hole 8, and this blind hole shape size is identical with through hole; Described through hole is provided with the bolt mating with it; Connect by stud, make the relative support member of sliding part removable and detachable; Certainly can also adopt flat key connection etc. to realize sliding part moves and fixing relative to support member.
Shown in Fig. 1-Fig. 2, described external thread length is greater than internal thread, due to external thread length slightly length can finely tune the height of support member.
Shown in Fig. 1-Fig. 2, described sliding part is provided with buffer part 9 by the surface of drill bit side, and this buffer part can be polyurethane buffering post or cushioning foam pad.
Sliding part can adopt the shapes such as semicircle sliding shoe or rectangular slab or circular slab.Support member can be that gripper shoe also can adopt back-up block, and its structure can adopt circle, or square.
The utility model is not limited to described embodiment; those skilled in the art is not departing from spirit of the present utility model openly in scope; still can do some corrections or change, therefore the scope that rights protection scope of the present utility model limits with claims is as the criterion.
