Description
Technical field
The utility model is relevant with screw (comprising bolt, screw) feed mechanism, specifically belongs to a kind of slide bar type screw cutting agency.
Background technology
In modern industry is produced, screw (screw and bolt) is one of the most frequently used securing member, and the Automatic Assembly Line involving screw assembling generally all will use screw automatic feed mechanism.In order to improve the operating efficiency of equipment, some apparatus automatization assemblings often arrange a temporary laying mechanism of screw in screw feeding process, this mechanism can remove the dust on screw in feed appliance on the one hand, and then be transported to next mechanism by screw switching mechanism, on the other hand by carrying screw also can reduce the time of delivery of screw in advance, thus enhance productivity.
Fig. 1 is to Figure 4 shows that a kind of existing slide bar type screw cutting agency, and it is mainly as the switching device shifter of between screw conveying glassware and screw tightening mechanism, comprises wire-feeding pipe 4, two guide fingers 2, slide block 1, pedestal 3, blanking seat 5 and silencers 6.Slide block 1 is for having the hollow structure of inner chamber 11, two guide fingers 2 are fixedly mounted on pedestal 3 that (sidepiece of pedestal 3 is formed with vertical block abreast, guide finger 2 one end is fixed on this vertical block, the other end is free state) and the two central axis in same level, slide block 1 is arranged on pedestal 3, two guide fingers 2 laterally run through slide block 1 and are partly arranged in slide block inner chamber 11, and slide block 1 can move on pedestal 3 along guide finger 2.There are bottom pedestal 3 two through holes, one of them through hole is positioned at immediately below wire-feeding pipe 4 and this through hole correspondence is provided with silencer 6, this silencer 6 can as exhaust and the filter of dust accumulation, above the blanking hole 51 that another through hole is positioned at blanking seat 5 and this through hole and blanking hole 51 up/down perforation.
Maximum spacing between two guide fingers 2 is less than the size of screw head, and minimum spacing is greater than the size in lead screw portion, when screw is blown into slide block inner chamber 11 by wire-feeding pipe 4, lead screw portion is positioned between two guide fingers that screw head rests on two guide fingers 2, now slide block 1 is in the first station, as shown in Figure 1.When this cutting agency obtain executive signal need switch time, slide block 1 moves to blanking seat 5 along two guide fingers 2 from the first station under the drive of drive unit (as cylinder, hydraulic cylinder etc.), when slide block 1 move to the through hole of slide block inner chamber 11 and pedestal 3, blanking seat 5 blanking hole 51 through time, slide block 1 is in the second station, as shown in Figure 2.
Move to the process of the second station at slide block 1 from the first station, screw can depart from the support of guide finger 2 and slide into the bottom (now contacting with pedestal 3 bottom screw) of slide block inner chamber 11, then under the drive of slide block 1, screw moves to the through hole above blanking hole 51, fall in blanking hole 51 due to the deadweight of screw self freely falling body, thus realize the effect to follow-up mechanism feed.
This mechanism in use; when screw departs from two guide fingers; as shown in Figure 3; easily cause that screw is beated, seat surface damage and blanking hole coarse; and then the situation causing generation screw to block; so not only add outage rate and the production cost of equipment, but also can cause product scrap phenomenon.In use also often there is the phenomenon having card screw in mechanism's handoff procedure in conventional screw blanking switching mechanism.
Utility model content

Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the utility model is described in further detail.
The slide bar type screw cutting agency that the utility model provides, comprises two guide fingers 2, slide block 1, pedestal 3, blanking seat 5, and slide block 1 to be located at slidably on pedestal 3 and to be had a slide block inner chamber 11.The sidepiece of pedestal 3 is formed with a vertical block, and one end of two guide fingers 2 is fixed on the vertical block of pedestal 3, and the other end is free state.Two guide fingers 2 flatly run through slide block 1, and central axis is in same level, and guide finger 2 part is arranged in slide block inner chamber 11 falls into slide block inner chamber 11 screw 7 with support.Pedestal 3 has a through hole, the central axis of this through hole and blanking hole 51 central axes of blanking seat 5.
In the utility model, distance between the free end (left end in free state) of guide finger 2 and stiff end (being fixed on the right-hand member on vertical block) is greater than the distance between the central axis of blanking hole 51 and the stiff end of guide finger 2, two guide fingers 2 are all formed with an inner fovea part 21, as shown in Figure 7, Figure 8, and inner fovea part 21 is positioned at directly over blanking hole 51, preferably, two inner fovea parts 21 center superposition and be positioned on the central axis of blanking hole 51.Screw 7 in slide block inner chamber 11 moves along guide finger 2 under the drive of slide block 1, when screw 7 moves to inner fovea part 21 place of guide finger 2, screw 7 comes off from guide finger 2, under the effect of self gravitation, fallen into the blanking hole 51 of blanking seat 5 by the through hole of pedestal 3, and then enter in follow-up mechanism.
As shown in Figure 7, the diameter of inner fovea part 21 is identical with the minimum diameter of the minimum diameter of through hole, blanking hole 51, and is all greater than diameter or the full-size of screw 7 head.
In order to ensure that screw successfully falls into follow-up mechanism, the through hole of pedestal 3, blanking hole 51 inwall of blanking seat 5 are all smooth, avoid the situation generation that screw blocks.
In addition, this cutting agency also comprises wire-feeding pipe 4 and silencer 6, and screw 7 is blown in slide block inner chamber 11 by wire-feeding pipe 4, also has a through hole bottom pedestal 3, this through hole is positioned at immediately below wire-feeding pipe 4 and this through hole correspondence is provided with silencer 6, the effect played exhaust and filter.
Operationally, screw 7 is entered in slide block inner chamber 11 by wire-feeding pipe 4 under airflow function in this mechanism, and screw 7 bar portion is positioned between two guide fingers 2, and screw 7 head receives the Kato of guide finger 2, and now slide block 1 is on the first station, as shown in Figure 5.When this mechanism obtain executive signal need switch time, drive unit is (as cylinder, hydraulic cylinder etc.) drive slide block 1 to move to blanking seat 5 along two guide fingers 2 from the first station, meanwhile, screw 7 also inwardly moves at recess 21 place along guide finger 2 under the drive of slide block 1, when screw 7 moves to the inner fovea part 21 place (through hole of slide block inner chamber 11 and pedestal 3 of guide finger 2, the blanking hole 51 of blanking seat 5 is through) time, screw 7 comes off from guide finger 2, fallen into the blanking hole 51 of blanking seat 5 by the through hole of pedestal 3 under the effect of self gravitation, as shown in Figure 6, now slide block 1 is in the second station.
The utility model structure is simple; low cost of manufacture; and can be improved on existing; by lengthening guide finger and form the inner fovea part corresponding with blanking hole on guide finger; thus make screw always by guide finger support until fall to blanking hole from inner fovea part; through millions of time practical applications test, there is not the situation that screw blocks, and then avoid the problem of product rejection and equipment downtime.
Be described in detail the utility model by specific embodiment above, this embodiment is only preferred embodiment of the present utility model, and it not limits the utility model.When not departing from the utility model principle; those of ordinary skill in the art to other embodiments all that the shape of inner fovea part on the length of guide finger and guide finger etc. is obtained by modes such as any amendment, equivalent replacement, improvement, all should be considered as in the technology category protected at the utility model under the prerequisite not making creative work.
