The specific embodiment

Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.

The utility model provides a kind of screw feedway.

With reference to Fig. 1, Fig. 1 is the structural representation of the utility model screw feedway preferred embodiment.

In the present embodiment, the screw feedway comprises the supply guide rail for drive screw, also comprises:

Support 10, this support 10 is used for the support screw feedway, support 10 comprise bottom surface 11, end face 12 and with bottom surface 11 and end face 12 sides 13 connected vertically, in the present embodiment, bottom surface 11 and end face 12 be for be arrangeding in parallel, and side 13 and bottom surface 11 and end face 12 are all vertical and be connected between bottom surface 11 and the end face 12.

Fixed panel 20 is arranged on the top of support 10, be provided with in the bottom surface of fixed panel 20 for the joint pin 21 of support 10, fixed panel 20 is fixed on the end face 12 of support 10 by joint pin 21; On fixed panel 20, optical sensor 22 also is set, it is used for should whether screw being arranged the zone at the area division internal induction that can sense light.

Motor 30 is fixed on the side 13 of support 10, is used for receiving the signal that starts or stops of optical sensor 22 transmissions, and begins to rotate or stop operating according to starting or stoping signal.

Axis 40 is defined as respectively fixed end 41 and supply side 42 with its two ends.Fixed end 41 is fixed on the bottom surface 11 of support 10, and supply side 42 is then passed end face 12 and the fixed panel 20 of support; Be provided with a supply disk 43 for feeding screw at the top of supply side 42, after supply side 42 is passed fixed panel 20, supply with the surface that disk 43 just is positioned at fixed panel 20.

When screw by after supplying with guide rail and being transported on the fixed panel 20, continue to be sent to and supply with on the disk 43, screw is being supplied with that disk 43 is fixed and is being rotated with supplying with disk 43, thereby screw is supplied with in single mode.

The utility model embodiment, the structure of the screw feedway that passes through to provide is when carrying out the screw supply, can make the screw accurate positioning, and owing to changed supply mode, eliminated the screw overlapping phenomenon that produces when supplying with, improved simultaneously the feed speed of screw.

In the above-described embodiments, the screw feedway also comprises:

Binary pair 50, this binary pair 50 also can be used for send starting and danger signal to motor 30, rotate and stop for its control.Be fixed on by its anchor shaft on the bottom surface 11 of support 10, an end of this anchor shaft is connected with the bottom surface 11 of support 10, and the other end is connected with the end face 11 of support 10; On anchor shaft, also be socketed a binary pair disk 51, and be provided with induction groove 52 at binary pair disk 51.

Binary pair photoinduction module 60, be fixed on the side 13 of support 10, it has an open end 61, and the upper and lower faces of this open end 61 contacts with lower surface with the upper surface of binary pair disk 51 respectively, thereby binary pair photoinduction module 60 is nested on the binary pair disk 51; And, carrying out photoinduction by open end 61, it is used for set induction groove 52 on the induction binary pair disk 51, when induction groove 52 turns in the open end 61, then receives danger signal, and this danger signal is sent to motor 30.

In the above-described embodiments, on fixed panel 20, also be provided with the screw positioning port 23 that will position for supplying with screw that guide rail transmits, after screw is sent to fixed panel by guide rail, at first be located by screw positioning port 23; Be provided with the fixed groove 431 that at least one is used for check screw at the edge of supplying with disk 43, when this fixed groove 431 when supplying with disk 43 and turn to the position relative with screw positioning port 23, just screw is fixed on this fixed groove 431, supplies with.In the present embodiment, the quantity of this fixed groove 431 can be set to four, and is equally spaced and is arranged on the edge of supplying with disk 43.

In the present embodiment, set induction groove 52 on binary pair disk 51, it has certain corresponding relation with the fixed groove 431 of supplying with on the disk 43, and namely binary pair disk 51 rotates weeks, by the induced effect of gear, the fixed groove 431 of supplying with on the disk 43 is once switched.

This above-mentioned executing in the example also is provided with a motor gear 31 above motor 30, it is connected with motor 30 by the turning cylinder that is arranged in the motor gear 31, and drives this motor gear 31 rotations by the rotation of motor 30;

Position corresponding with motor gear 31 on axis 40 arranges shaft gear 44 in, and shaft gear 44 is socketed on the axis 40 in this; Middle shaft gear 44 is meshed with motor gear 31, rotates by shaft gear 44 in the rotation drive of motor gear 31;

On the anchor shaft of binary pair 50, be provided with binary pair gear 53 with middle shaft gear 44 corresponding positions, this binary pair gear 53 is positioned at the top of binary pair disk 51, be meshed with middle shaft gear 44, after shaft gear 44 rotated in the rotation of motor gear 31 drives, middle shaft gear 44 just further drove binary pair gear 53 and rotates.

In the above-described embodiments, on fixed panel 20, also be provided with when motor 30 and receive danger signal that optical sensor 22 sends and after stopping operating, be used for blocking the backgauge sheet 24 of screw.

The screw feedway that the utility model embodiment provides, its principle of work is:

Screw is transported to fixed panel 20 by supplying with guide rail, a screw is passed through, and be located by screw positioning port 23, waits for that fixed groove 431 is fixed.When in optical sensor 22 is sensed its sensitive volume, not having screw, optical sensor 22 starts, and sends actuation signal to motor 30, and motor 30 begins to rotate, drive motor gear 31 and rotate, and further rotate simultaneously by shaft gear 44 and binary pair gear 54 in motor gear 31 drives.At this moment, middle shaft gear 44 can drive supply disk 43 and rotate together, when the fixed groove 431 on being positioned at its edge turns to the position relative with screw positioning port 23, by supplying with the effect of guide rail, screw slips into fixed groove 431, and is fixed on the fixed groove 431, at this moment, the screw that to supply with in the guide rail by backgauge sheet 24 blocks, and supplies with being used for;

When fixed groove 431 turned to the relative position of screw positioning port 23, the induction groove 52 on the binary pair disk 51 just in time was arranged in the open end 61 of binary pair photoinduction module 60.When screw on fixed groove 431 when supplying with disk 43 and be rotated further to the sensitive volume of optical sensor 22, optical sensor 22 sends danger signal to motor 30 simultaneously with binary pair photoinduction module 60, motor 30 stops operating, and waits for that screw is extracted.

After this screw is extracted, optical sensor 22 is sensed in its sensitive volume does not have screw, again start, and send actuation signal to motor 30, simultaneously, binary pair photoinduction module 60 also begins to start, and because the induced effect of gear, after triggering disk 51 and rotating weeks, next fixed groove 431 just turns to the position relative with screw positioning port 23 with supplying with disk 43, and next screw is fixed on the fixed groove 431, thereby supply with next time.

Adopt in such a way, because supply mode becomes single supply by the traditional supply in a row of one-tenth, thereby can eliminate the overlapping phenomenon of screw; Simultaneously and since the mode that screw is supplied with by reciprocation type to rotary transformation, thereby improved screw supplying speed; And, adopting the structure of the screw feedway that the utility model embodiment provides, owing to supply with the fixing comparatively stable of disk, therefore, can not occur by impacting or vibrations cause that screw jumps out phenomenon.

The above only is preferred embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure transformation that utilizes the utility model specification sheets and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
