Abstract
The present invention relates to screw is carried out during a kind of mechanical structure field, more particularly, to lock screw the filature dop of correcting.A kind of filature dop, including collet body, described collet body is provided with the feeding channel of the inner chamber for screw is sent into collet body, the driver bit passage pushing for driver bit, the lower end of collet body is radially provided with 3 circular through holes, it is provided with pellet in described through hole, the lower end of described collet body is additionally provided with spring detent, described spring detent is circumferentially distributed along collet body lower end, the lower end of described spring detent exceeds the bottom of described collet body, and the bottom diameter of described spring detent is less than or equal to screw diameter.Compare prior art, the present invention is provided with for by the spring detent of screw correcting using collet body lower end, in screw dropping process, after spiral shell collet body is stretched out in one end of screw, correcting spacing is carried out by spring detent to screw, it is to avoid screw occurs crooked cannot falling in specified screw.
Description
Technical field
The present invention relates to mechanical structure field, especially relate to screw carries out during a kind of lock screw the filature dop of correcting.
Background technology
In a lot of plant equipment assembling field all uses such as machinery, electronics, one kind installed by screw is electric lock screwdriver to screw,
Another kind is special screw locking machine, and electric lock screwdriver needs to put manually screw, and workman locks screw, high labor intensive,
Inefficiency, thus increased production cost；Special screw locking machine occurs that in feeding process get stuck or completely expect shows
As also the screw not having correcting being locked in product, cause scrapping of product.
General screw chuck is simple due to structure, does not possess for being accurately positioned to screw hole position in Handheld screw machine, and
And there is no the function that deep hole positioning lock pays it is difficult to effectively play guide effect to screw when product hole position is combined；Furthermore,
At present being all integrated (as shown in Figure 1) of screw chuck product on the market, that is, dop and Gripper body are whole for one
Body structure, when screw falls in chuck, is susceptible to crooked (as shown in Figure 3), thus askew after causing screw locking
Situation that is oblique or cannot locking.
Content of the invention
The purpose of the present invention is：A kind of filature dop is provided, can be carried out in automatic lock screw using this filature dop
Correcting, prevents screw crooked, it is to avoid train off the problem that screw or screw hole position do not align.For realizing this purpose, the present invention adopts
Use following technical scheme：
A kind of filature dop, including collet body, described collet body is provided with for sending into screw in collet body
The feeding channel in chamber, the driver bit passage pushing for driver bit, the lower end of collet body be radially provided with 3 circular
Through hole, is provided with pellet in described through hole, the lower end of described collet body is additionally provided with spring detent, and described spring detent is along collet body
Lower end is circumferentially distributed, and the lower end of described spring detent exceeds the bottom of described collet body, and the bottom of described spring detent
Diameter is less than or equal to screw diameter.Be to allow screw smoothly to fall, the driver bit passage in collet body with diameter greater than institute
State the diameter of screw terminal, screw continue after pellet fall, fall during, collet body lower end spring detent
Screw can be corrected, it is to avoid screw hold angle.
Further, the upper end of described spring detent is less than or flushes in the lower end of described through hole.
Further, described spring detent forms for phosphorus bronze sheet.The ductility of phosphorus bronze sheet, fatigue durability are all preferable, and its elastic force
Good, dial and insert steadily.
Further, described manhole is evenly distributed along the periphery in described collet body.Through hole is evenly distributed along the periphery,
Ensure that stress equalization in screw dropping process.
Further, described pellet forms point with the screw terminal of screw and contacts.
Compare prior art, and the present invention is provided with for by the spring detent of screw correcting, screw falls using collet body lower end
During, after spiral shell collet body is stretched out in one end of screw, correcting spacing is carried out by spring detent to screw, it is to avoid screw
Generation is crooked cannot to be fallen in specified screw, or crooked situation about squeezing into；Spring-like is made using phosphor-copper, and elastic force is good, both
Can guarantee that correcting in screw dropping process and spacing, avoid problem that is excessive due to elastic force and affecting screw locking simultaneously.

Specific embodiment
With reference to embodiment and accompanying drawing, the invention will be further described.
Embodiment 1
As shown in figure 4, a kind of filature dop, including collet body 1, described collet body 1 is provided with for by screw conveying
Enter the feeding channel 2 of the inner chamber of collet body 1, the driver bit passage 3 pushing for driver bit, under collet body 1
End is radially provided with the through hole 4 of 3 circles uniformly arranged, and is provided with pellet 5, under described collet body 1 in described through hole 4
End is additionally provided with the spring detent 6 being made up of phosphorus bronze sheet, and described spring detent 6 is circumferentially distributed along collet body 1 lower end, described spring
The lower end of pawl 6 exceeds the bottom of described collet body 1, and the bottom diameter of described spring detent 6 is less than or equal to screw
Diameter, the upper end of described spring detent 6 is less than or flushes in the lower end of described through hole 4.
Described pellet 5 forms point with the screw terminal of screw and contacts.
As seen in figs. 5-6, the filature dop of the present invention is when screw falls through pellet 5, the lower end to screw for the spring detent
Guided and positioned, thus avoiding the crooked of screw.
Finally it should be noted that：Above example only not limits technical scheme described in the invention in order to the present invention to be described；
Therefore, although this specification with reference to each above-mentioned embodiment to present invention has been detailed description, this area
It is to be appreciated by one skilled in the art that still the present invention can be modified or equivalent；And all are without departing from the present invention
The technical scheme of spirit and scope and its improvement, it all should be covered in scope of the presently claimed invention.
