Description
Technical field:
The utility model belongs to frock clamp field, is specifically related to a kind of elongated tool sharpening instrument.
Background technology:
Elongated tool sharpening is a difficult problem for tool sharpening always, because its drill bit is long, for avoiding fractureing in drill bit reconditioning process or cutter radial is beated greatly, need to be fixed elongated tool by special sharpening instrument, and the clamping of existing sharpening instrument to elongated tool is more loaded down with trivial details, be not easy to support elongated tool, and cannot ensure its rigidity in elongated tool sharpening process, its grinding quality is poor, efficiency is low.
Summary of the invention:
The utility model provides a kind of elongated tool sharpening instrument, and its structure is simple, and installation and removal are convenient, and strong adaptability, versatility is good, is convenient to carry out clamping and support to drill bit, can ensure the rigidity of drill bit during sharpening.
Elongated tool sharpening instrument of the present utility model, the technical scheme adopted is: comprise support set, lengthen nut main body and grip shank, the front end lengthening nut main body connects support set, rear end connects grip shank, lengthens and is provided with spring chuck between nut main body and grip shank.
As further improvement of the utility model, support set is carbide alloy support set, and wearability is good.
As further improvement of the utility model, be interference fit between support set and lengthening nut main body, its fit clearance is little, effectively can ensure grinding quality.
As further improvement of the utility model, lengthening nut main body for being threaded, is convenient to assembly and disassembly with grip shank.
As further improvement of the utility model, the front end of spring chuck is fixed on and lengthens in nut main body.
As further improvement of the utility model, the inside of grip shank has through hole, and the shank of elongated tool may extend in grip shank.
The beneficial effects of the utility model are: the utility model to be fixedly clamped drill bit by spring chuck, and carries out conical surface location, its convenient mounting and clamping, and the axiality of clamping is good; Supported by the part to be grinding of support set to drill bit, it supports reliable, can ensure the rigidity of drill bit during sharpening; Support set adopts Hardmetal materials to make, and wearability is good; Support set is interference fit with lengthening nut main body, and its fit clearance is little, effectively can ensure grinding quality.The utility model overall structure is simple, and strong adaptability, can be made into the sharpening instrument of various sizes to adapt to the elongated tool of different-diameter, different length; Its versatility is good, by the direct clamping of grip shank in chuck or hydraulic pressure chuck, is applicable to general-purpose grinder or five-shaft numerical control grinding machine, is with a wide range of applications and space.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention:
With reference to Fig. 1, this elongated tool sharpening instrument, comprises support set 1, lengthens nut main body 2 and grip shank 4, and the front end lengthening nut main body 2 connects support set 1, rear end connects grip shank 4, lengthens and is provided with spring chuck 3 between nut main body 2 and grip shank 4.Support set 1 is carbide alloy support set.Be interference fit between support set 1 and lengthening nut main body 2.Lengthen nut main body 2 with grip shank 4 for being threaded.The front end of spring chuck 3 is fixed on and lengthens in nut main body 2.The inside of grip shank 4 has through hole.
During use, first support set 1 is pressed in an interference fit in the front end of lengthening nut main body 2, grip shank 4 is installed to chuck on grinding machine or hydraulic clip puts, then the afterbody of drill bit is goed deep in grip shank 4, afterwards the head of drill bit passed successively spring nut 3 and lengthen nut main body 2, make partial denudation to be grinding outside support set 1, finally connect and lengthen nut main body 2 and grip shank 4, the meeting holddown spring chuck 3 when lengthening nut main body 2 and tightening with grip shank 4, thus make spring chuck 3 clamp elongated tool.
