Abstract
The invention discloses a special-purpose drill for hole drilling. The special-purpose drill for hole drilling comprises a drill body and a drill stock, wherein the drill body is fixedly connected with the drill stock; the drill body comprises a depth limiting device and a drill tip arranged in the depth limiting device; the drill tip is provided with a spiral chip groove; the whole drill stock is a cylindrical drill stock; the diameter of the cylindrical drill stock is sequentially reduced gradually from the other end which is far away from the drill body to the tail end of the drill stock so that the frustum-shaped drill stock is formed; the depth limiting device has a thickness limiting structure mainly; a central axis of the depth limiting device serves an axis of the drill tip; and the drill tip penetrates in the whole drill. The special-purpose drill for hole drilling has the advantages that the special-purpose drill for hole drilling comprises the depth limiting device and the drill tip arranged in the depth limiting device, the drill tip is provided with the spiral chip groove, a helical angle of the chip groove is 15-30 degrees, chips can be removed effectively, the probability of scrappage of products is reduced, by the depth limiting device, a required hole drilling depth can be confirmed effectively, wood cannot be pierced thoroughly, and the work efficiency and the work accuracy are improved.
Description
Technical field
The present invention relates to a kind of boring target drill, belong to machining tool field.
Background technology
Drill bit (Drills) goes out through hole or blind hole in order to drilling on solid material, and can to the cutter of existing hole reaming.Conventional drill bit mainly contains fluted drill, chit drill, centre drill, depth drill and cylindrical drill.
In architectural engineering, electric drill is a kind of common tool, and user can be operated by electric power motor, impels drill bit fast rotational, punches, and carries out other operations so that follow-up.In this process, hole depth is an important parameter, specifically need regulate according to real needs.
Drill bit is the cutter that boring is commonly used, drill bit is when holing, mainly through cutter head top, workpiece is cut, by chip area, chip is discharged, if chip can not be discharged very smoothly, the hole inwall bored then can be caused to occur cut, workpiece is even caused to become waste product, during drill bit design, the helical angle of chip area directly affects the speed of its chip removal, the larger chip removal of helical angle is more smooth and easy, but, chip also can be larger to the wearing and tearing of drill bit, helical angle is less, chip removal can be slow, relatively little to bit wear, existing drill bit normally arranges three chip areas, chip area is narrow, so helical angle is usually smaller, chip removal is slow, there is cut in easy causing hole inwall.
What just need some to fix sometimes during timber boring drills through the degree of depth, therefore needs a kind of structure simple, drills through degree of depth convenience and wield instrument, meets the demand in contemporary work.
Summary of the invention
The object of this invention is to provide a kind of boring target drill, effective chip removal can be accomplished, reduce the probability of product reimbursement, and the setting of depth limiting device, can effectively determine required drilling depth, can not wear thorough for timber, raise labour efficiency and the work degree of accuracy.
The technical solution used in the present invention is: a kind of boring target drill, comprise drill bit and drillstock, drill bit is fixedly connected with drillstock, described drill bit comprises depth limiting device and is arranged at the apex point in depth limiting device, described apex point is provided with helical form chip area, and the helical angle of described chip area is 15 ~ 30 °;
Described drillstock whole installation is column type drillstock, and this column type drillstock successively decreases successively to drillstock tail end diameter from the other end away from drill bit, overall formation circular platform type drillstock, described depth limiting device overall structure is: its innovative point is: described depth limiting device is mainly rugosity position limiting structure, apex point for axis, runs through whole drill bit with depth limiting device central shaft.
On this basis, described rugosity position limiting structure is: comprise the limited mouth B being provided with fixed thickness, the length 8 ~ 10cm less of the length of apex point of this limited mouth B.
On this basis, the opening part of described limited mouth B is also provided with postive stop baffle, and this postive stop baffle perpendicular to apex point, and is fixedly connected on the position of the opening part 2 ~ 5cm of distance limited mouth B.
On this basis, described depth limiting device is also provided with deep spiral shape chip area, the helical angle of described deep spiral shape chip area is 30 ~ 45 °.
Beneficial effect of the present invention is as follows:
(1) boring target drill of the present invention, comprise depth limiting device and be arranged at the apex point in depth limiting device, apex point is provided with helical form chip area, the helical angle of chip area is 15 ~ 30 °, can accomplish effective chip removal, reduces the probability of product reimbursement, and the setting of depth limiting device, can effectively determine required drilling depth, can not wear thorough for timber, raise labour efficiency and the work degree of accuracy;
(2) boring target drill of the present invention, rugosity position limiting structure is: comprise the limited mouth B being provided with fixed thickness, length 8 ~ the 10cm less of the length of apex point of this limited mouth B, the opening part of limited mouth B is also provided with postive stop baffle, the wood chip produced when effectively can isolate boring that arranges of baffle plate enters on drill body, this postive stop baffle is perpendicular to apex point, and be fixedly connected on the position of the opening part 2 ~ 5cm of distance limited mouth B, can both ensure to drill through the required degree of depth, can ensure that again the threaded bore of apex point drills through completely, structure is simple, easy to use.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is described in further details.
Fig. 1 is that the present invention holes target drill overall structure schematic diagram.
Detailed description of the invention
The present invention relates to a kind of boring target drill, as shown in Figure 1: comprise drill bit 1 and drillstock 2, drill bit 1 is fixedly connected with drillstock 2, drill bit 1 comprises depth limiting device and is arranged at the apex point 3 in depth limiting device, apex point 3 is provided with helical form chip area 31, and the helical angle of chip area 31 is 15 ~ 30 °; Drillstock 2 whole installation is column type drillstock, and this column type drillstock successively decreases successively to drillstock 2 tail end diameter from the other end away from drill bit 1, and entirety forms circular platform type drillstock,
