Abstract
The present invention provides a kind of auxiliary positioning set of electric screw driver, can guarantee that the cutter head of electric screw driver is axial axially coincident with screw hole location in electric screw driver the turn of the screw, reduce the sliding teeth phenomenon of the turn of the screw, improve the quality of the turn of the screw process.The auxiliary positioning includes positioning sleeve ontology and the inner sleeve that is mounted on electric screw driver, the bottom centre of the positioning sleeve ontology is equipped with the taper protrusion for blocking screw hole location, the middle part of the taper protrusion is equipped with the location hole passed through for the cutter head of electric screw driver, taper location shoulder is equipped between the inner bottom surface and inner wall of the positioning sleeve ontology, the second taper location shoulder is equipped between the bottom surface and side wall of the inner sleeve, the cutter head of the electric screw driver passes through the bottom center of inner sleeve.
Description
Technical field
The present invention relates to hardware machining tool technical fields, and in particular to a kind of auxiliary positioning set of electric screw driver.
Background technique
Currently, in the assembling medium occasion of workshop, it is often necessary to use electric screw driver and carry out the turn of the screw operation.Tradition
Manual electric screw driver, be all not equipped with the structure of positioning, cause in the turn of the screw, the cutter head of electric screw driver it is axial with
The axial direction of screw hole location is not overlapped, and deviation is larger, therefore sliding teeth phenomenon frequent occurrence.And for the product of less set screw
For, a sliding teeth screw hole location can scrap entire product casing, lead to the wasting of resources.
Summary of the invention
The purpose of the present invention is to propose to a kind of auxiliary positioning sets of electric screw driver, can be in electric screw driver the turn of the screw
Guarantee that the cutter head of electric screw driver is axial axially coincident with screw hole location, reduces the sliding teeth phenomenon of the turn of the screw, improve the turn of the screw
The quality of process.
The auxiliary positioning set of the electric screw driver provided according to the present invention, including positioning sleeve ontology and it is mounted on electronic spiral shell
Inner sleeve on silk knife, the bottom centre of the positioning sleeve ontology are equipped with the taper protrusion for blocking screw hole location, the cone
The middle part of shape protrusion is equipped with the location hole that passes through of cutter head for electric screw driver, the inner bottom surface and inner wall of the positioning sleeve ontology it
Between be equipped with taper location shoulder, between the bottom surface and side wall of the inner sleeve be equipped with the second taper location shoulder, the electronic spiral shell
The cutter head of silk knife passes through the bottom center of inner sleeve.
The auxiliary positioning of electric screw driver of the invention covers in use, the bottom surface of positioning sleeve ontology is first placed on product
On the end face of screw hole location, and the bottom centre of positioning sleeve ontology is made to be stuck in the counterbore opening of screw hole location, it then again will be electric
It can start the turn of the screw work in inner sleeve alignment insertion positioning sleeve ontology on dynamic screwdriver；It is interior after inner sleeve insertion
Second taper location shoulder of sleeve is axially bonded with the intrinsic taper location shoulder of positioning sleeve, it is ensured that electric when the turn of the screw
The cutter head of dynamic screwdriver is axial axially coincident with screw hole location, to avoid sliding teeth phenomenon, reduces sliding teeth product rejection rate, mentions
High yield quality.
Further, the bottom edge round-corner transition of the positioning sleeve ontology.Round-corner transition at this can prevent from positioning
Scrape the lacquer painting of flower prod in the bottom surface of set ontology.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of positioning sleeve ontology of the invention.
Fig. 2 is the structural schematic diagram of electric screw driver of the invention.
Fig. 3 is position fixing process structural schematic diagram of the invention.
Specific embodiment
It is for example related each to a specific embodiment of the invention by the description to embodiment below against attached drawing
The shape of component, construction, the mutual alignment between each section and connection relationship, the effect of each section and working principle etc. are made into one
The detailed description of step.
Such as Fig. 1,2,3, the auxiliary positioning set of electric screw driver of the invention, including positioning sleeve ontology 1 and it is mounted on electricity
Inner sleeve 3 on dynamic screwdriver 2, the bottom centre of positioning sleeve ontology 1 are equipped with the taper protrusion 11 for blocking screw hole location, cone
The middle part of shape protrusion 11 is equipped with the location hole 111 that passes through of cutter head 21 for electric screw driver 2, the inner bottom surface of positioning sleeve ontology 1 and
It is equipped with taper location shoulder 12 between inner wall, the second taper location shoulder 31 is equipped between the bottom surface and side wall of inner sleeve 3, it is electronic
The cutter head 21 of screwdriver 2 passes through the bottom center of inner sleeve 3.
The auxiliary positioning of electric screw driver of the invention covers in use, the bottom surface of positioning sleeve ontology 1 is first placed on product
Screw hole location end face on, and the bottom centre of positioning sleeve ontology 1 is made to be stuck in the counterbore opening of screw hole location, then again will
It can start the turn of the screw work in the alignment insertion positioning sleeve ontology 1 of inner sleeve 3 on electric screw driver 2；3 are inserted due to inner sleeve to enter
Afterwards, the second taper location shoulder 31 of inner sleeve 3 is axially bonded with the taper location shoulder 31 in positioning sleeve ontology 1, Ke Yibao
The axial direction with screw hole location of the cutter head 21 of electric screw driver 2 is axially coincident when demonstrate,proving the turn of the screw, to avoid sliding teeth phenomenon, reduces
Sliding teeth product rejection rate improves product quality.
As preferred embodiment, 13 round-corner transition of bottom edge of positioning sleeve ontology 1.Round-corner transition at this, can
To prevent the bottom surface of positioning sleeve ontology 1 from scraping the lacquer painting of flower prod.
