Abstract
The invention relates to a chamfering and perforating tool, which comprises a tool body. A tool bit is provided at one end of the tool body. The chamfering and perforating tool has the characteristics that a tool handle is arranged at the other end of the tool body, elastic components are distributed between the tool handle and the tool bit, and seal assembly is distributed at each of two ends of the tool handle at the same time. Therefore, the machining depth of the tool can be adjusted by effectively utilizing springs which are arranged between the tool bit and the tool handle, so as to make the chamfer sizes at different positions to be basically the same, thereby meeting the machining requirements.
Description
Technical field
The present invention relates to a kind of cutter, relate in particular to a kind of chamfering perforate cutter.
Background technology
With regard at present, for guaranteeing that screw can waltz through installing hole in the installation process, the guiding in the time of when machining, can increasing chamfering as installation in the aperture of installing hole usually.The mode of existing chamfering is to adopt the chamfering that is complementary with the installing hole size to bore mostly.
But; When processed blank distortion does not have rule than big and distortion; Because the working depth of the cutter of setting is certain; It is very big that the chamfering that common chamfering is bored processing tends to show the some places chamfering, and the some places chamfering is very little even do not have this uneven situation of chamfering, can't meet the demands.
Summary of the invention
The objective of the invention is to overcome the above problem that prior art exists, a kind of chamfering perforate cutter is provided.
For realizing a kind of chamfering perforate of the object of the invention cutter, include cutter body, an end of said cutter body is distributed with cutter head, and wherein: the other end of said cutter body is provided with handle of a knife; Be distributed with elastic parts between described handle of a knife and the cutter head; Described handle of a knife two ends are distributed with black box.
Further, above-mentioned a kind of chamfering perforate cutter, wherein, described cutter head is provided with position-limited edge.
Further, above-mentioned a kind of chamfering perforate cutter, wherein, described elastic parts is a spring.
Further, above-mentioned a kind of chamfering perforate cutter, wherein, described black box is an O-ring seals.
Again further, above-mentioned a kind of chamfering perforate cutter, wherein, the terminal contact jaw with cutter body of described handle of a knife is provided with shaft retaining ring.
Adopt technical scheme of the present invention,, can effectively utilize the working depth of spring adjustment cutter, make the chamfering size basically identical of diverse location, can meet the demands owing between cutter head and handle of a knife, be provided with spring.
The object of the invention, advantage and characteristics will illustrate through the non-limitative illustration of following preferential embodiment and explain that these embodiment only provide with reference to accompanying drawing as an example.
Description of drawings
Fig. 1 is the organigram of this chamfering perforate cutter.
The implication of each Reference numeral is following among the figure:
1 cutter body, 2 handle of a knifes
3 spring 4O shape sealing rings
5 shaft retaining rings, 6 cutter heads
The specific embodiment
A kind of chamfering perforate cutter as shown in Figure 1 includes cutter body 1, and an end of this cutter body 1 is distributed with cutter head 6, and its unusual part is: the other end of the cutter body 1 that the present invention adopted is provided with handle of a knife 2.And, be distributed with elastic parts between this handle of a knife 2 and the cutter head 6.Simultaneously, handle of a knife 2 two ends are distributed with black box.
In conjunction with the present invention's one preferred implementation, suitable spacing in order to let the non-blade port end of cutter head 6 that the movement locus of elastic parts is carried out, avoid elastic parts to get loose from cutter head 6, the cutter head 6 that the present invention adopted is provided with position-limited edge.
Further, consider that cutter head 6 can carry out suitable activity under the effect of elastic parts.Specifically, in order to let cutter head 6 under stressed certain situation, can adjust the working depth of cutter automatically according to the distance between blank and the cutter smoothly, make the chamfering size basically identical of diverse location, the elastic parts that the present invention adopted is a spring 3.
Again further, the black box that the present invention adopted is an O-ring seals 4.Like this, can effectively satisfy between cutter body 1 and the handle of a knife 2 and have sufficient sealing, not influence under the movable situation of cutter head 6, prevent to add between the entering handle of a knife 2 and cutter body 1 of dust such as aluminium bits in man-hour, guarantee the activity effect of cutter head 6.And the terminal contact jaws with cutter body 1 of handle of a knife 2 are provided with shaft retaining ring 5, and the end that can effectively prevent cutter body 1 unnecessary rocking occur and influences the processing effect of cutter head 6.Simultaneously,, can also effectively avoid knife bar ejection when spring 3 unclamps, improve processing safety through the existence of shaft retaining ring 5.
From implementation process of the present invention; Make cutter head 6 under the effect of spring 3, carry out contraction-like activity up and down; The stressing conditions of cutter head 6 is certain during this period; Because the distance between blank and the cutter is also confirmed, so the working depth of the automatic adjustment of the elastic reaction of spring 3 meeting cutter, make the chamfering size basically identical of diverse location.
Through above-mentioned character express and combine accompanying drawing to find out, adopt the present invention after owing between cutter head and handle of a knife, be provided with spring, can effectively utilize the working depth of spring adjustment cutter, make the chamfering size basically identical of diverse location, can meet the demands.
Certainly, more than only be concrete exemplary applications of the present invention, protection scope of the present invention is not constituted any limitation.Except that the foregoing description, the present invention can also have other embodiment.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop within the present invention's scope required for protection.
