Embodiment
Further illustrate technical scheme below in conjunction with the accompanying drawings and by embodiment.
Preferred embodiment one
This preferred embodiment discloses a kind of feed device, is designed for the special-shaped workpiece 2 of both sides bending. The structure of special-shaped workpiece 2 is not limited, as long as both sides carry bending angle.Specifically, above-mentioned workpiece 2 is returned Receive is to include workpiece main body 22 and be fixedly installed on the bending wall 21 of both sides in workpiece main body 22, both sides bending Wall 21 is upwardly or downwardly bent simultaneously, as shown in Figure 2.
As shown in figure 1, the feed device of the present embodiment includes two branch for be arrangeding in parallel and being spaced setpoint distance Bar 1, the both sides bending wall 21 of workpiece 2 is supported with the bending angle of the formation of workpiece main body 22 to be hung on pole 1 and can Slided along pole 1, two poles 1 tilt along set angle, and workpiece 2 slides into bottom from the high-end of pole 1 Skid off.Two poles 1 are not only the sliding rail of workpiece 2, and have the special-shaped workpiece 2 of both sides bending Sequence it is stable be maintained at specific modality i.e. two bending angle down and two bending angles be left-right situs form (and It is non-in tandem) conveyed.
In order to ensure that two poles 1 can support to set form that (two bending angles are down and two bending angles For left-right situs form) enter workpiece 2, exclude with form in tandem enter workpiece 2, set two The distance between axles of pole 1 is more than the width of workpiece 2 and less than the length of workpiece main body 22.
In order to prevent the phenomenon of two or more workpiece 2 stacking, set in the top of two poles 1 There is depression bar 3, depression bar 3 is parallel with pole 1 and is set with pole 1 in convex structure.Workpiece main body 22 is worn Between depression bar 3 and pole 1.Vertical direction between depression bar 3 and pole 1 is set according to the size of workpiece 2 Distance, depression bar 3 can exclude in addition to bottommost workpiece other stack when workpiece 2 occur and stack phenomenon Workpiece.In order to prevent that the setting of depression bar 3 from influenceing entrance and the bottom workpiece 2 of pole 1 of the high-end workpiece 2 of pole 1 Skid off, the two ends of depression bar 3 is shorter than pole 1.
Two poles 1 are under the drive of vibrating device with setpoint frequency and setting amplitude vibration.It is preferred that, shake Dynamic device is the straight device that shakes.Workpiece 2 is slided with the vibration of pole 1 to the bottom of pole 1.The straight device that shakes is set Determine frequency determine workpiece 2 sliding speed, the setting amplitude for the device that directly shakes depending on the quality and size of workpiece 2, Can vibrate workpiece 2.
Preferred embodiment two
This preferred embodiment discloses a kind of vibrating disk.As shown in figure 3, the vibrating disk includes tubular hopper 4 With vibrating chassis 5, tubular hopper 4 is fixedly installed on vibrating chassis 5 and shaken under the drive of vibrating chassis 5 Dynamic, vibrating disk also includes the feed device of preferred embodiment one, and tubular hopper 4 is used to convey to feed device Workpiece 2.By modes such as artificial or mechanical arms into tubular hopper 4 feeding.Tubular hopper 4 is in vibration Vibrated under the drive on chassis 5 and export the rambling workpiece 2 in bottom to feed device, feed device pair Workpiece 2 in unqualified form carries out screening exclusion, bending angle is supported to the workpiece 2 hung on pole 1 steady Surely be delivered at follow-up automatic assembly equipment or following process machinery at.The vibrating disk of the present invention makes workpiece 2 Arrangement it is more neat in order.
Vibrating chassis 5 are that electromagnetic vibration or electric motor type vibrate.The output workpiece 2 of tubular hopper 4 of vibration Mode do not limit, as long as workpiece 2 can be exported.It is preferred that, tubular hopper 4 passes through helical orbit 6 To export workpiece 2.Specifically, helical orbit 6 is arranged on the inwall of tubular hopper 4 and its one end stretches out tubular material Bucket 4, two poles 1 it is high-end in arcuate structure corresponding with the outer wall of tubular hopper 4 and with stretching out tubular hopper One end docking of 4 helical orbit 6.Workpiece 2 is moved along helical orbit 6 from the bottom up of tubular hopper 4, And slip into pole 1 from the end that helical orbit 6 is located at outside.
Because pole 1 can carry out screening exclusion to the workpiece 2 of unqualified form, therefore, the lower section of pole 1 Splicing groove 7 is set.Splicing groove 7 is arcuate structure close to the high-end side of pole 1 and is fixedly connected on tubular material Struggle against 4 outer walls, and helical orbit 6 stretches out the part of tubular hopper 4 and is fixedly installed on inside splicing groove 7.Due to The workpiece 2 being excluded near the low side of pole 1 is less, therefore splicing groove 7 stretches out tubular hopper 4 and sets length , without isometric with pole 1, prevent that vibrating disk is unstable.
The know-why of the present invention is described above in association with specific embodiment.These descriptions are intended merely to explain this The principle of invention, and limiting the scope of the invention can not be construed in any way.Based on herein Explain, those skilled in the art, which would not require any inventive effort, can associate other tools of the present invention Body embodiment, these modes are fallen within protection scope of the present invention.
