Abstract
The utility model relates to a screw lead-in head of a full-automatic or semi-automatic screw locking machine. The screw lead-in head comprises a lead-in head main body, wherein an electric granted mouth channel passing through the main body from top to bottom is arranged in the main body, and the lower end of the electric granted mouth is a screw discharge hole; the side wall of the main body is obliquely downwards provided with a screw feed channel, and the lower end of the screw feed channel coincides with the screw discharge hole; and the electric granted mouth channel is divided into an upper section and a lower section, the inner diameter of the upper section is larger than the inner diameter of the lower section, and the lower section is communicated with the screw feed channel. According to the screw lead-in head, the electric granted mouth channel is divided into two sections, wherein the inner diameter of the upper section is large, and the inner diameter of the lower section is small, so that a space of a crossing part of the electric granted mouth channel and the screw feed channel is reduced, a screw running track is more reliably restrained, the phenomena of screw clamping and rolling over, and the like in the screw running process are eliminated, and the running of the whole machine is more stable and reliable; and in addition, the screw discharge hole is processed from top to bottom, so that steps formed during processing the screw discharge hole are eliminated, the phenomenon of screw clamping is eliminated, and the discharge direction of the screws is better guaranteed.
Description
Technical field
The screw that the present invention relates to a kind of automatic locking filature imports head and improves structure.
Background technology
It is the core that guarantees that the smooth and easy entering of screw is subscribed the position and docked smoothly with the electric screwdriver mouth that screw full-automatic or semi-automatic screw locking machine imports head, and specification requirement is high.It is last inferior thick and the aperture is bigger that existing most screw imports an electric screwdriver mouth passage, screw be in operation occur easily blocking, phenomenon such as upset, cause entire machine not run well.
Summary of the invention
In view of this, the present invention's technical problem that will solve provides a kind of screw turnover screw smooth and easy, the not full-automatic or semi-automatic screw locking machine of bail and imports head.
The present invention adopts following scheme to realize:
A kind of screw full-automatic or semi-automatic screw locking machine imports head, comprises the importing head main body, in main body, is provided with the electric screwdriver mouth passage that runs through main body from the top down; Electric screwdriver mouth passage lower end is the screw discharging opening; Be tilted in body wall and be arranged with the screw feeding-passage, screw feeding-passage lower end overlaps with the screw discharging opening, and described electric screwdriver mouth passage is divided into two sections; The epimere internal diameter is greater than the hypomere internal diameter, and hypomere is communicated with the screw feeding-passage.
As improvement to such scheme; The screw discharging opening is provided with a pair of screw locating clip; Screw locating clip middle part is movably installed in through shop bolt and imports on the head main body; Between screw locating clip top and the importing head main body stage clip is installed, screw locating clip lower inner wall is provided with the semicircle orifice that stops that screw directly drops from the screw discharging opening, and the semicircle orifice on the two-screw locating clip is formed circular port; The circular port diameter has the inclined plane that the downward direction diameter reduces gradually less than the nut external diameter of screw at the circular port inwall.
The present invention is divided into two-part with electric screwdriver mouth passage; The epimere internal diameter is big; The hypomere internal diameter is little, has dwindled the space of electric screwdriver mouth passage and screw feeding-passage crossover location, has retrained the track of screw operation more reliably; Eliminated phenomenons such as screw bail upset in service, made the entire machine operation more reliable and more stable.In addition, the discharging opening of screw is processed from top to bottom, adds formed step in man-hour thereby eliminated the screw discharging opening, has eliminated the bail phenomenon, has also better guaranteed the discharging direction of screw.
Description of drawings
Fig. 1 imports head main body stereoscopic-state structural representation for the embodiment of the invention.
Fig. 2 imports head main body cross-sectional structure sketch map for present embodiment.
Fig. 3 is that the whole screw of present embodiment imports an overall structure sketch map.
Fig. 4 is that the whole screw of present embodiment imports a decomposing state structural representation.
The specific embodiment
Below will combine accompanying drawing and embodiment that the present invention is described in further detail for the ease of it will be appreciated by those skilled in the art that:
The screw of the full-automatic or semi-automatic screw locking machine that present embodiment discloses imports scalp acupuncture existing screw is imported the defective that head exists, and can make the turnover of screw and electric screwdriver mouth more smooth and easy, guarantees the stable operation of machine.
Like accompanying drawing 1, shown in 2.The screw that present embodiment discloses imports head and comprises importing head main body 1, in main body 1, is provided with the electric screwdriver mouth passage 2 that runs through main body 1 from the top down, and electric screwdriver mouth passage 2 lower ends are screw discharging opening 3; In main body 1 sidewall slope to being arranged with screw feeding-passage 4; Screw feeding-passage 4 lower ends overlap with screw discharging opening 3, and wherein, electric screwdriver mouth passage 2 is divided into two sections; The epimere internal diameter is greater than the hypomere internal diameter, and hypomere is communicated with screw feeding-passage 4.This epimere of electric screwdriver mouth passage 2 structural design big, that hypomere is little has been dwindled the space of electric screwdriver mouth passage 2 with screw feeding-passage 4 crossover locations; Retrained the track of screw operation more reliably; Eliminated phenomenons such as screw upset bail in service, made the entire equipment operation more reliable and more stable.
In the present embodiment; Screw discharging opening 3 is provided with a pair of screw locating clip 5; Screw locating clip 5 middle parts are movably installed in through shop bolt 6 and import on the head main body 1; Between screw locating clip 5 tops and the importing head main body 1 stage clip 7 is installed, screw locating clip 5 lower inner wall are provided with the semicircle orifice 8 that stops that screw directly drops from screw discharging opening 3, and the semicircle orifice on the two-screw locating clip 5 is formed circular port; The circular port diameter has the inclined plane 81 that the downward direction diameter reduces gradually less than the nut external diameter of screw at the circular port inwall.
When screw moves to screw discharging opening 3; Clamp screw through screw locating clip 5, screw can freely not fallen from screw discharging opening 3, when the electric screwdriver mouth withstands screw and promotes screw when moving; Screw squeezes opens two-screw locating clip 5, gets into and subscribes the installation that screw is accomplished in the position.
In addition; When screw feeding-passage 4 in adding cost importing head main body 1 and screw discharging opening 3; Can begin to process from the top down from screw feeding-passage 4 import departments; Avoided like this that screw tapping channel 4 adds formed step in man-hour in the existing processing mode, also further eliminated the bail phenomenon, also better guaranteed the discharging direction of screw.
More than be wherein concrete implementation of the present invention, it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to claim of the present invention.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the present invention's design, can also make some distortion and improvement, these conspicuous replacement forms all belong to protection scope of the present invention.
