Abstract
The invention relates to an equal-normal-rake drill bit with scales. The drill bit comprises a cutting part and a drill handle, wherein the cutting part comprises an outer edge cutting edge and a cutting edge groove, the scales are arranged on the cutting edge groove, a support frame is arranged on the drill handle in a way of going around the drill handle for a circle, two springs are arranged on the support frame, one end of each spring is fixedly arranged on the support frame, the other end of each spring is respectively and fixedly provided with a pointer, the two springs are in parallel arrangement on the support frame, and a transparent protection cover is movably arranged on the outer side of each spring on the support frame. The scales are arranged on the cutting edge groove of the drill bit, in addition, the scales can be clearly indicated through the arrangement of the pointers, in addition, one movable transparent protection cover is arranged at the outer side of each spring, the scales can be seen from the outside of the protection covers, the injury on workers is avoided, in addition, the protection covers are movable, and a part of fine chips can be accommodated. The equal-normal-rake drill bit has the advantages that the structure is novel, and the operation is convenient, the work time is shortened, so the work efficiency is improved.
Description
Technical field
The invention belongs to technical field of tools, relate to a kind of drill bit specifically, especially a kind of with scale and have protective device etc. method Orthogonal Rake Drill.
Background technology
Drill bit 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 etc., but most drill bit can not accurately measure the degree of depth drilled through, particularly the higher object of depth requirements is drilled through to some, if drill through, the degree of depth is large can damage object, if it is little to drill through the degree of depth, then also need secondary to drill through, lose time, if the degree of depth of the viewing boring of user's close together is easy to be spattered wound by carefully cutting of splashing.
Summary of the invention
In order to solve the problem, the invention provides a kind of have scale can more accurate metering drill through the degree of depth and have protection device etc. method Orthogonal Rake Drill.
In order to achieve the above object, the present invention is achieved by the following technical solutions:
The present invention is that one is with the method Orthogonal Rake Drills such as graduated, drill bit comprises cutting portion and drillstock, cutting portion comprises outer rim sword and flute, flute is provided with scale, within one week, support is provided with on drillstock, around drillstock, support is provided with two root springs, and one end of every root spring is fixed on support, and the other end of every root spring is fixedly installed pointer respectively.
Further improvement of the present invention is: two springs be arranged in parallel on support.
Further improvement of the present invention is: on support, the outside of every root spring is movably set with transparent shield.
The invention has the beneficial effects as follows: drill bit of the present invention is provided with scale on flute, and there is pointer clearly can indicate scale, and to have in the outside of spring can be movable transparent protective cover, scale can be seen in the outside of protective cover, can not damage staff, and protective cover is movable, can hold a part and carefully cut.
Novel structure of the present invention, easy to operate, the degree of depth drilled through can accurately be known according to the scale on flute, shorten the working time, thus improve operating efficiency, and the protector of drill bit protects staff from what carefully cut spatters wound.
Accompanying drawing explanation
Fig. 1 is the present invention is structural representation.
Wherein: 1-drillstock, 2-outer rim sword, 3-flute, 4-support, 5-spring, 6-protective cover, 7-pointer.
Detailed description of the invention
In order to deepen the understanding of the present invention, be described in further detail the present invention below in conjunction with drawings and Examples, this embodiment, only for explaining the present invention, not forming protection scope of the present invention and limiting.
As shown in Fig. 1, the present invention is that one is with the method Orthogonal Rake Drills such as graduated, described drill bit comprises cutting portion and drillstock 1, described cutting portion comprises outer rim sword 2 and flute 3, described flute 3 is provided with scale, flute 3 is provided with scale, make staff can know the degree of depth drilled through accurately when drilling through, and do not affect the use of drill bit, on described drillstock 1, within 1 one weeks, support 4 is provided with around described drillstock, described support 4 is provided with two root springs 5, one end of spring 5 described in every root is fixed on described support 4, described in every root, the other end of spring 5 is fixedly installed pointer 7 respectively, pointer 7 clearly can indicate scale, accurate, described two springs 5 be arranged in parallel on described support 4, the spring 5 be arranged in parallel can occur in the both sides of flute, so pointer clearly can point to scale, on described support 4, the outside of spring 5 described in every root is movably set with transparent protective cover 6, can prevent from carefully cutting to spatter hindering staff, and be movable setting between protective cover and described support, even if produce the normal work of carefully cutting and also can not block drill bit in the process of work, be tending towards even etc. the anterior angle of each point on the main sword of method Orthogonal Rake Drill, 1.5-2 can be improved doubly etc. the durability of method anterior angle, torque reduces about 20%.
Drill bit of the present invention is provided with scale on flute, and there is pointer clearly can indicate scale, and to have in the outside of spring can be movable transparent protective cover, scale can be seen in the outside of protective cover, can not damage staff, and protective cover is movable, can hold a part and carefully cut.
Novel structure of the present invention, easy to operate, the degree of depth drilled through can accurately be known according to the scale on flute, shorten the working time, thus improve operating efficiency, and the protector of drill bit protects staff from what carefully cut spatters wound.
