Abstract
The invention relates to a drillings remover for removing drillings attached on the surface when workpieces are drilled by a drill. The drill comprises a clamping part, a drill stem and a head part. The clamping part and the head part are oppositely arranged at both ends of the drill stem; the drillings remover is in a cylindrical structure and comprises a flexible deforming main body, a fixed end and a drillings removing end; the flexible deforming main body is sheathed on the drill stem and can be retracted along the axial direction of the drill stem; the inside diameter of the flexible deforming main body is not less than the outside diameter of the drill stem; the fixed end and the drillings removing end are arranged at both opposite ends of the flexible deforming main body; the fixed end is arranged at one end of the flexible deforming main body close to the clamping part and is fixed on the clamping part; and the drillings removing end is arranged at one end of the flexible deforming main body close to the drill head part and is in a disc-like structure surrounding one circle of the flexible deforming main body. When the drillings remover drills, the disc-like drillings removing end can remove the drillings away and prevents the removed longer drillings from winding on the drillings remover and the drill again. Besides, the invention also provides a drill with the drillings remover.

The specific embodiment
See also Fig. 1 and Fig. 2, a kind of scaper 100 that embodiment of the present invention provides.Debris removal when described scaper 100 is used for drill bit 200 processing works 300.Described drill bit 200 comprises clamping part 210, drilling rod 220 and head 230.Described clamping part 210 and head 230 are relatively arranged on the two ends 221,222 of described drilling rod 220.Described clamping part 210 is processed with cannelure 211 and is used for fixing described scaper 100.
Described scaper 100 is tubular structures.In the present embodiment, described scaper 100 is cylindric.Described scaper 100 comprises dilatation main body 10, stiff end 20 and debris removal end 30.
Described dilatation main body 10 is sheathed on the described drilling rod 220, and can be along the axial stretching of described drilling rod 220.In the present embodiment, described dilatation main body 10 is made by spring steel.Certainly, described dilatation main body 10 also can adopt other elastomeric materials to make, for example rubber, plastics, macromolecular material etc.Length during described dilatation main body 10 full extension approximates the length of drilling rod 220.Described dilatation main body 10 comprises sidewall 11.Offer groove 12 on the described sidewall 11.The internal diameter of described sidewall 11 is D1.The inside diameter D 1 of described sidewall 11 is more than or equal to the outer diameter D 2 of described drilling rod 220.In the present embodiment, the inside diameter D 1 of described sidewall 11 is a bit larger tham the outer diameter D 2 of described drilling rod 220.Described groove 12 both can be many curved grooves of offering around described sidewall 11 circumferencial directions, also can be a continuous helicla flute of offering around described sidewall 11 circumferencial directions.In the present embodiment, described groove 12 is opened on the described sidewall 11 by spirality, and be beneficial to smear metal liquid and can be flushed to described drilling rod 220 easily, and can be so that described dilatation main body 10 elasticity are better.When described drill bit 200 did not adopt smear metal liquid, described dilatation main body 10 also can not comprise groove 12.
Described stiff end 20 and debris removal end 30 are arranged at the relative two ends 13,14 of described dilatation main body 10.Described stiff end 20 and debris removal end 30 are integrative-structures with described dilatation main body 10.Described stiff end 20 is arranged at the end 13 of described dilatation main body 10 near described clamping part 210, and is fixed on the described clamping part 210.In the present embodiment, described stiff end 20 is clamped in the cannelure 211 of described clamping part 210.Certainly, described stiff end 20 also can adopt and be spirally connected or mode such as engaging is fixed on the described drill bit 200.
Described debris removal end 30 is arranged at the end 14 near described drill bit 200 heads 230.Described debris removal end 30 is the disk-like structure around described dilatation main body 10 1 circles.Described debris removal end 30 can be the roughly the same umbrella-shaped structure of shape with described drill bit 200 heads 230, also can be planar structure.In the present embodiment, described debris removal end 30 adopts the planar disc structure.In the present embodiment, the internal diameter of described debris removal end 30 is D3, and the inside diameter D 3 of described debris removal end 30 is more than or equal to the outer diameter D 2 of described drilling rod 220.In the present embodiment, the inside diameter D 3 of described debris removal end 30 is a bit larger tham the outer diameter D 2 of described drilling rod 220.
See also Fig. 2 and Fig. 3, when drill bit 200 is not started working, described scaper 100 is clamped in the cannelure 211 of described clamping part 210 by described stiff end 20.And debris removal end 30 is resisted against on the surface of described workpiece 300, and described dilatation main body 10 is in the full extension state.When drill bit 200 carried out work, described scaper 100 was along with drill bit 200 rotates together, because debris removal end 30 is subjected to stopping of workpiece 300 surfaces, so described debris removal end 30 compresses described dilatation main body 10 during along with the downward drilling of drill bit 200.Drilling cuttings 310 when discharging owing to be subjected to stopping of described debris removal end 30, will be away from drill bit 200.Described debris removal end 30 is designed to disc structure and not only drilling cuttings is arranged, even and drilling cuttings when very long because the large tracts of land of described debris removal end 30, can be so that the drilling cuttings that is arranged can't rewind on scaper 100 and the drill bit 200.
See also Fig. 4 and Fig. 5, a kind of scaper 400 that provides for second embodiment of the invention.The scaper 100 that the described scaper 400 and first embodiment provide is basic identical, and its difference is do not have groove on the dilatation main body 410 of described scaper 400, and this scaper 400 can use under the environment that need not smear metal liquid.When described scaper 400 was worked, its dilatation main body 410 was compressed, owing to do not have groove on the dilatation main body 410, but itself be to make by elastomeric material, so the sidewall 411 of described dilatation main body 410 can limpen in compression.
The debris removal end of scaper provided by the invention its disk-like structure when drilling can with drilling cuttings to around arrange and being wound into again on scaper and the drill bit of preventing to arrange than the jumping chisel bits.
Those skilled in the art will be appreciated that; above embodiment only is to be used for illustrating the present invention; and be not to be used as limitation of the invention; as long as within connotation scope of the present invention, appropriate change and variation that above embodiment is done all drop within the scope of protection of present invention.
