The specific embodiment
Below in conjunction with accompanying drawing and preferred embodiment the utility model is described further.
Be illustrated in figure 1 as the utility model embodiment; Described centreless grinding automatic feeding 1 comprises: feed bin 10 is arranged on material fetching mechanism (comprising pusher slide block 8 and material loading wedge 2) on the feed bin sidewall and the feed mechanism (comprising first order pusher compound table 3, second level pusher compound table 4 and deflector chute 5) that is positioned at the end of material fetching mechanism; Control electronic box 6 is used for controlling the power set operation of automatic feeding mechanism, and lathe fixed head 7 is used for automatic feeding is fixed on centerless grinder.Material fetching mechanism is arranged on the sidewall 12 of feed bin 10, is convenient to extract the blank that is stored in the feed bin 10.
In the embodiment of the utility model, the base plate 11 and the sidewall 12 of feed bin 10 complement each other to form v-shaped structure, and wherein sidewall 12 is vertically to be provided with, and base plate 11 is inclined to set, and material fetching mechanism then is arranged on the sidewall 12.The sidewall 12 that vertically is provided be for make material fetching mechanism pushing away when getting blank, avoid pushing a plurality of blanks, and base plate 11 be inclined to set, can make be stored in that feed bin 10 inner blanks slide into material fetching mechanism automatically get material district, the i.e. bottommost of feed bin 10.Among the figure, the base plate 11 double bulkheads of making feed bin of feed bin 10 are convenient to putting into and slide into and getting material district of blank; In the present embodiment, also bulkhead can be set in addition, and base plate 11 links to each other with bulkhead and forms the shaped as frame structure; But the inclination that keeps base plate 11; Like this, both increased the memory space of feed bin, and blank had been slipped into automatically get material district (being the bottom position place of sidewall 12).
Material fetching mechanism comprises: be arranged on the push rod on the feed bin sidewall and be arranged on the pushing head on push rod top; Wherein of Fig. 1, push rod is the material loading wedge 2 of the wedge shape that links to each other with pusher slide block 8 for long block-shaped pusher slide block 8, pushing head, and the cylinder of the bottom of pusher slide block 8 bottom being arranged on feed bin links to each other; Pusher slide block 8 and material loading wedge 2 all are arranged on the sidewall 12 of feed bin 10, sidewall 12 be provided with pusher slide block 8 and material loading wedge 2 to corresponding groove, so that pusher slide block 8 and material loading wedge 2 sink in the groove.Material wedge 2 is shaped as wedge shape, and its wedge shape position protrudes from the surface of sidewall 12, and the upper surface of this wedge shape and sidewall 12 acutangulate setting, can landing so that it can extract blank.Pusher slide block 8 drives material loading wedge 2 and moves up and down under the driving of cylinder, and its stroke upwards can arrive the top of sidewall 12, can reach the bottom of sidewall 12 downwards.Pusher slide block 8 also can be tooth bar transmission, band transmission etc. except by being arranged on cylinder under the feed bin drives, and the preferred cylinder of present embodiment is as power set, because of cylinder structure is simple, and convenient the setting.
Can fix between pusher slide block 8 and the material loading wedge 2, also can among a small circle, rotate, as shown in Figure 2; In the utility model embodiment, material loading wedge 2 is connected with pusher slide block 8 through hinge 21, and; The junction of material loading wedge 2 is positions of skew outside its center of gravity lower direction sidewall 12, and like this, material loading wedge 2 can be in the position that protrudes from sidewall 12 always; When material loading wedge 2 moves down; Receive the blank extruding that is stored in the feed bin example, in the groove of material loading wedge 2 meeting indentation sidewalls, wear and tear thereby avoid material loading wedge 2 to move down in the process.Certainly, a spring or other elastic components can be set also between material loading wedge 2 and the pusher slide block 8, utilize elastic component that material loading wedge 2 is ejected in the grooves, when the extruding that receives blank in the indentation groove.
In addition, the height that material loading wedge 2 protrudes from feed bin sidewall 12 is greater than the radius of blank and less than the diameter of 1.5 times of blanks, so that it can once only extract a blank and also can not drop.In the present embodiment, the diameter of height and blank that material loading wedge 2 protrudes from feed bin sidewall 12 is suitable.
The feed mechanism of the utility model embodiment comprises: the deflector chute 5 that is arranged on feed bin sidewall 12 outsides; Be provided with the compound table of blank being pushed to the two-stage cylinder propelling of centreless grinding on the deflector chute 5, comprise first order pusher compound table 3 and second level pusher compound table 4.The propelling stroke summation of two compound tables can make blank arrive the Working position of centreless grinding.In the present embodiment, first order pusher compound table 3 is to be formed by the cylinder combination that two series connection are provided with second level pusher compound table 4, can certainly use a cylinder to accomplish; But the needed cylinder body length of cylinder itself is longer; Influence taking up room of complete machine, thus a plurality of cylinder tandem compounds can be selected for use, to reduce the shared space of cylinder; Use small-sized cylinder simultaneously, can practice thrift more cost.
In the utility model embodiment; Centreless grinding automatic feeding 1 comprises that also one is used to control the control electronic box 6 of material fetching mechanism and feed mechanism; And be used for centreless grinding automatic feeding 1 is fixed to the lathe fixed head 7 on the centerless grinder; Be fixed to purpose on the centerless grinder and be to make their position relative fixed, improve the accuracy of feeding.
Above content is the further explain that combines concrete preferred implementation that the utility model is done, and can not assert that the practical implementation of the utility model is confined to these explanations.For the those of ordinary skill of technical field under the utility model, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be regarded as belonging to the protection domain of the utility model.
