Detailed description of the invention
Below with reference to the accompanying drawings and in conjunction with the embodiments, the present invention is described in detail:
As Figure 1-Figure 8 for embodiments of the invention, the double-slider double cam screw feeding transmission mechanism that this embodiment provides, including frame 1, feed mechanism 2, feed mechanism 3 and sweeping through the material mechanism 4, coordinate Figure of description 1-8 that each composition mechanism is described in detail below, the most each Figure of description, in order to see structure and the details of inside more intuitively, simplifies members.
nullAs shown in Figure 1-Figure 3，Wherein feed mechanism 2 includes the screw lifting push pedal 210 that screw 100 is delivered to feed mechanism 3，The top of screw lifting push pedal 210 is inwardly angled domatic，Screw lifting push pedal 210 is arranged on screw storehouse base plate 21，And it is each provided with one in the both sides of feed mechanism 3，As shown in Figure 1，Screw lifting push pedal 210 connects a pan feeding motor 27 making its oscilaltion campaign，Screw lifting push pedal 210 is to slide up and down on the opening that screw storehouse base plate 21 is arranged，And it is arranged on the inner side of screw storehouse base plate 21，Screw storehouse base plate 21 all slopes inwardly in Outboard Sections and the front part of the lifting push pedal 210 of its relative screw，I.e. screw lifting push pedal 210 is positioned at the minimum point of screw storehouse base plate 21，Screw storehouse base plate 21 and stock support 36 and shell not shown in the diagram are assembled into storing screws 100 and each side screw storehouse 211 of；The lifting carriage track 28 for screw lifting push pedal 210 motion it is provided with in frame 1, pan feeding motor 27 drives gear 23 to be connected by mair motor gear 29 with the screw lifting being arranged on feed mechanism 3 both sides, screw lifting drives gear 23 by a straight-bar and the screw lift drive shaft seat 22 of a fixation, connecting and have a lifter cam 25, the lifting slide bar 24 being fixed on lifter cam 25 is slidably connected with the lifting slider 26 being fixed in screw lifting push pedal 210.
Illustrating in conjunction with the above-mentioned structure about feed mechanism 2, the process that feed mechanism 2 completes feeding is as follows:
(1), the screw 100 in screw storehouse 211 is put into, due to the intilted design of screw storehouse base plate 21 so that screw 100 is prone to fall in screw lifting push pedal 210；
(2), after machine startup, pan feeding motor 27 drives mair motor gear 29 to rotate, and mair motor gear 29 drives screw lifting to drive gear 23 to rotate, and screw lifting drives gear 23 to drive lifter cam 25 to rotate；
(3), with reference to Fig. 3, during lifter cam 25 rotates, the lifting slide bar 24 being fixed on lifter cam 25 rotates with lifter cam 25, thus carry out the circular motion in vertical direction, and the change in displacement in vertical direction is acted in screw lifting push pedal 210 by lifting slider 26, screw lifting push pedal 210 carries out moving back and forth of rise and fall along lifting carriage track 28；
(4), when screw lifting push pedal 210 rises to peak, due to inwardly angled domatic, the screw 100 in screw lifting push pedal 210 starts inside landing, thus falls on feed mechanism 3.
Illustrate and complete the process of feeding in conjunction with the above-mentioned structure about feed mechanism 2, screw for both sides lifts how push pedal 210 coordinates and be described as follows: the lifting slide bar 24 arranging both sides presents the angle of certain dislocation when original position, the screw lifting push pedal 210 making both sides completes the raising and lowering of dislocation, i.e. side is when rising, opposite side is decline state or remains stationary as, and i.e. completes alternately feeding.
In conjunction with the above-mentioned description about feed mechanism 2, this feed mechanism 2 is described as follows compared to the beneficial effect of prior art:
(1), the upper spiral shell of both sides dislocation, for the mechanism that spiral shell go up in both sides simultaneously, the time halves, and on one side, spiral shell falls into the probability of feed mechanism 3 and compares with both sides basically identical, so efficiency raising is close to twice；Walk due to screw 100 is linear motion, compared to screw in impeller-type 100 walk be circular motion for, in this mechanism, the frequency of upper spiral shell is higher, and it is shorter i.e. to go up the spiral shell cycle, so in hgher efficiency.
(2) noise that the friction, being different from vibrating-disk between collision and screw 100 and the shell shaking in caused noise, swing type between each screw 100 between vibrating disk and screw 100 in a large number is caused, in this feed mechanism 2, screw 100 is geo-stationary during rising, screw 100 lifts push pedal 210 landing to during feed mechanism 3 being all slow slip, so noise is less from screw storehouse 211 landing to screw lifting push pedal 210 and from screw.
(3), the area of screw lifting push pedal 210 is little, and it is positioned at the extreme lower position in screw storehouse 211, when screw 100 is less, landing to screw lifts in push pedal 210, screw 100 still can be made when rising to peak to fall on feed mechanism 3, and the arrangement machine of impeller-type, when screw 100 is less, although cylinder is constantly rotating, but a small amount of bottom screw 100 can be deposited in the bottom of cylinder, without carrying out bigger rolling along with cylinder, the probability that i.e. screw 100 falls on feed mechanism 3 greatly reduces, so this feed mechanism 2 is when screw 100 is less, still can reach higher upper spiral shell rate.
null(4)、Screw lifting push pedal 210 is each provided with one in the both sides of feed mechanism 3，When in screw storehouse 211, screw 100 is more，Although amassing the screw 100 above screw lifting push pedal 210 also can be more，But during rising again，Screw 100 can an automatic landing part，When arriving peak，Sake owing to tilting starts landing，The screw 100 not falling into screw recess 33 can fall into the screw storehouse 211 of opposite side，Only it is left least a portion of being deposited on feed mechanism 3，Entered the effect of sweeping through the material mechanism 4 also can drop both sides，In the process，Screw 100 circulates，Upper spiral shell probability keeps consistent substantially，Comprehensive with above-mentioned (3)，I.e. adapt to screw more than 100 and few situation，Comparatively speaking，Personnel are needed to put the time interval of screw 100 elongated，Personnel cost reduces.
nullSuch as Fig. 1-Fig. 2、Shown in Fig. 4，Wherein feed mechanism 3 includes stock support 36，The both sides of stock support 36 connect vibrations suspension 31，Stock support 36 is provided with the screw track 32 for carrying screw 100，Screw track 32 includes the screw recess 33 accommodating screw 100，The width of screw recess 33 is more than the lead screw width of screw 100，And less than the screw terminal width of screw 100，Stock support 36 is connected with vibrations double-track cam 34 by vibrations roller 38，Shake double-track cam 34 in the structure with vibrations roller 38 intersection as shown in Figure 4: the two sides of vibrations double-track cam 34 is each provided with a trajectory profile，And vibrations roller 38 is between the trajectory profile on two sides，Distance between the trajectory profile on two sides is always consistent，And for shaking the diameter of roller 38，It it is the visite that the gradient is bigger after wherein trajectory profile is the long slope that the gradient is less；Vibrations double-track cam 34 connects has one to supply its vibrations rotated driving gear 35, and these vibrations drive gear 35 to engage connection vibrations travelling gear 37, shakes travelling gear 37 and connects a screw lifting driving gear 23 making it rotate.
Illustrating in conjunction with the above-mentioned structure about feed mechanism 3, the process that feed mechanism 3 completes feeding is as follows:
(1), the screw 100 in screw lifting push pedal 210 starts inside landing, thus fall on screw track 32, now, the lead screw of segment screw 100 is down, when contacting with screw track 32, fall in screw recess 33, owing to the width of screw recess 33 is less than the screw terminal width of screw 100, so the screw terminal of screw 100 is stuck in screw recess 33；
(2), screw lifting drives gear 23 to be rotated by the drive of pan feeding motor 27, vibrations travelling gear 37 is driven to rotate, vibrations travelling gear 37 drives vibrations to drive gear 35, thus drive vibrations cam 34 to rotate, vibrations cam 34 contacts with the vibrations roller 38 being fixed on stock support 36, thus drives the screw 100 in screw recess 33 to travel forward.
Illustrate in conjunction with said mechanism about the structure of feed mechanism 3 and complete the process of feeding, being described as follows about the proal principle of screw 100 in screw recess 33:
(1), in order to more preferably illustrate, orientation according to Fig. 4, the trajectory profile on the two sides of vibrations double-track cam 34 is respectively designated as front trajectory profile and rear trajectory profile, the visite of trajectory profile after vibrations roller 38 is climbed up, extruding between vibrations roller 38 and vibrations double-track cam 34 produces a thrust backward, now, owing to the gradient is bigger, within the of short duration time, the distance of horizontal displacement is bigger, the thrust produced is more than the stiction between screw recess 33 and screw 100, make to move respectively between screw recess 33 and screw 100, owing to acting on the thrust of screw recess 33 more than the force of sliding friction between screw recess 33 and screw 100, so the distance that screw recess 33 is moved is than screw more than 100 backward；
(2), when shaking the long slope that roller 38 slips into rear trajectory profile, the position that screw 100 falls before the position ratio in screw recess 33 is forward, the i.e. relative screw recess 33 of screw 100 is advanced, simultaneously, there is a thrust forward on the long slope of the front trajectory profile contacted to vibrations roller 38, make to shake roller 38 to move slowly on the long slope that the gradient is less, now, the dynamics acting on stock support 36 is less, it is not enough to offset the stiction between screw recess 33 and screw 100, so screw recess 33 and screw 100 keep geo-stationary, but screw 100 along with before screw recess 33 so that advance,
(1) and (2) in sum, in including the whole cycle of long slope and visite, the mass motion of screw recess 33 be backward motion after move the most forward, its initial position keeps consistent with final position, and screw 100 is less due to the distance moved backward, distance forward is more, so its final position is more forward than initial position, so that screw 100 travels forward slowly.
nullSuch as Fig. 1-Fig. 2，Shown in Fig. 5-Fig. 8，Wherein sweeping through the material mechanism 4 includes the hairbrush 41 being arranged on above screw track 32，Hairbrush 41 is connected with hairbrush pitman shaft 46 by hairbrush connecting plate 42，Tail end at hairbrush pitman shaft 46 connects a brush gear 43，Brush gear 43 is engaged on a brush gear connecting rod 44，This brush gear connecting rod 44 is fan-shaped，Brush gear connecting rod 44 connects hairbrush push rod roller 45，As we can see from the figure，On connecting plate between brush gear connecting rod 44 and hairbrush push rod roller 45 fluted，Coordinate with the limited screw being arranged on side，Thus hairbrush push rod roller 45 is carried out spacing and protection，Connect on hairbrush push rod roller 45 and have a hairbrush cam 47 making it move up and down，Hairbrush cam 47 connects the screw lifting having to make it rotate and drives gear 23.
In conjunction with Fig. 8, as follows about the structure specification of hairbrush cam 47: in terms of four sides of hairbrush cam 47, to be labeled as A, B, C, D, wherein the cross section of A side is semicircle, and rotate centrally disposed for semicircular circle, when making it run with A face, hairbrush push rod roller 45 remains constant with the distance in A face, and wherein the cross section of B, D side is the line segment being parallel to each other, wherein the cross section of C side is the waveform of three semicircle compositions, C1、C2、C3
For the point of respectively three semicircles, C1、C3For two points farthest from the central pivot point rotated, C2For a point nearest from the central pivot point rotated.
nullIn conjunction with the above-mentioned structure explanation about sweeping through the material mechanism 4，The process that sweeping through the material mechanism 4 carries out sweeping through the material is as follows: screw lifting drives gear 23 to be rotated by the drive of pan feeding motor 27，Band electric brush cam 47 rotates，Hairbrush cam 47 band electric brush push rod roller 45 moves up and down，Hairbrush push rod roller 45 drives brush gear connecting rod 44 to move，When the left side of brush gear connecting rod 44 rises or falls along with hairbrush push rod roller 45，Due to lever principle，The right side of brush gear connecting rod 44 drives brush gear 43 counterclockwise or to rotate clockwise，So that hairbrush 41 carries out motion back and forth，Spacing between hairbrush 41 and screw recess 33 is shorter，In the lead screw of screw 100 does not falls within screw recess 33，Screw 100 couches above screw recess 33，The hairbrush 41 moved back and forth is inswept，The screw 100 not falling within screw recess 33 is swept by hairbrush 41，Fall in the screw storehouse 211 of both sides.
Illustrate and carry out the work process of sweeping through the material in conjunction with the above-mentioned structure about sweeping through the material mechanism 4, about being described as follows that hairbrush cam 47 band electric brush push rod roller 45 moves up and down:
(1), as shown in Figure 5, the central pivot point rotated with electric brush cam 47 is arranged on the semicircular center of circle, as when the hairbrush push rod roller 45 A face at hairbrush cam 47, owing to being always maintained at constant from the center rotated, so hairbrush push rod roller 45 remains stationary as, now hairbrush 41 is positioned at the left side of stock support 36, and the description about left side and right side is with stock support 36 as reference in this paragraph；
(2), along with turning clockwise, when the hairbrush push rod roller 45 B face at hairbrush cam 47, the B face of hairbrush cam 47 from the central pivot point rotated increasingly away from so that hairbrush push rod roller 45 constantly rises under the effect of hairbrush cam 47, hairbrush 41 does counterclockwise movement, i.e. moves right；As shown in Figure 6, as the C reaching C face1Time, now hairbrush 41 is positioned at the right side of stock support 36, i.e. completes the left side process to right side, and this is sweeping through the material action for the first time；
(3) as it is shown in fig. 7, then landing is to the C in C face2Time, now hairbrush 41 is positioned at the left side of stock support 36, i.e. completes the right side process to left side, and this is second time sweeping through the material action；
(4), then landing to the C in C face3Time, now hairbrush 41 is positioned at the right side of stock support 36, i.e. completes the left side process to right side, and this is third time sweeping through the material action；
(5), being then return to D face, now hairbrush 41 returns to the left side of stock support 36, i.e. completes the right side process to left side, and this is the 4th sweeping through the material action；
(6), finally, A face is returned to from D face, circulation.
To sum up during (1) to (6), about the design of hairbrush cam 47, produced by have the beneficial effect that: hairbrush cam 47 is during rotating a circle, and hairbrush 41 carries out four sweeping through the material actions altogether, simultaneously because from C1To C2、C2To C3During the time shorter, so speed, the sweeping through the material dynamics of formation is relatively big, so that sweeping through the material result is more preferable.
In conjunction with above with respect to feed mechanism 2, feed mechanism 3, the explanation of sweeping through the material mechanism 4, it is described as follows about the gearing between three mechanisms:
