Detailed description of the invention
Below in conjunction with accompanying drawing of the present utility model, the technical scheme in this utility model embodiment is carried out clear, complete
Describe, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole embodiments wholely.
Based on the embodiment in this utility model, those of ordinary skill in the art are obtained under not making creative work premise
Every other embodiment, broadly falls into the scope of this utility model protection.
The structure of the pay-off of the present embodiment is as shown in Figure 1.This pay-off is the position feeding of horizontal parallel parallel duplex
Structure (the most once can send two pieces material 24) simultaneously, pay-off include servo feeding mechanism, guide bar 18, guide head 19,
Passage 20, for storing storage bin hopper 21 and the single choice mechanism 22 of material 24.
With reference to Fig. 2, Fig. 3 and Fig. 4, servo feeding mechanism includes mounting seat 11, feeding servomotor 12, toothed belt transmission machine
Structure, ball screw 16 and ball screw nut 17, feeding servomotor 12 and ball screw 16 are respectively arranged in mounting seat 11,
Ball screw nut 17 is set on ball screw 16, and feeding servomotor 12 drives ball screw by synchronous belt drive mechanism
16 rotate, thus drive ball screw nut 17 to move on ball screw 16.Decision design, synchronous belt drive mechanism includes
One synchronous pulley 13, Timing Belt 14 and the second synchronous pulley 15, the first synchronous pulley 13 is set in turning of feeding servomotor 12
On axle, the second synchronous pulley 15 is set in one end of ball screw 16, and Timing Belt 14 is connected to the first synchronous pulley 13 He
Second synchronous pulley 15.Decision design, ball screw nut 17 is fixed with guide pin bushing 182, mounting seat 11 is fixed with guide post
181, guide post 181 is parallel with ball screw 16, and sleeve 182 is set on 181.One end of guide bar 18 is connected to ball screw
Nut 17, the other end is fixed with a guide head 19.Mounting seat 11 is fixed in one end of passage 20, and the other end is connected to numerical control
The chuck 23 of lathe.Being machined with a guide through hole 201 on passage 20, this guide through hole 201 is on the length direction of passage
Through, passage 20 is also processed an opening 202, this opening 202 is connected with guide through hole 201.Guide head 19 is loaded on guide
In through hole 201, servo feeding mechanism drives guide bar 18 so that guide head 19 moves in guide through hole 201.
With reference to Fig. 5 and Fig. 6, storage bin hopper 21 being machined with blanking channel 211, blanking channel 211 is connected with opening 202, storage
Material 24 in hopper 21 is by sending into material 24 in blanking channel 211 guide material through hole 201.Single choice mechanism 22 is installed on blanking
At passage 211, single choice mechanism 22 includes mounting bracket the 221, first single choice cylinder the 222, first catch the 223, second single choice cylinder
224 and second catch 225.Mounting bracket 221 is fixed on storage bin hopper 21, the first single choice cylinder 222 and the second single choice cylinder 224
Being respectively arranged in mounting bracket 221, the first catch 223 and the second catch 225 are individually fixed in the work of the first single choice cylinder 222
Stopper rod and the piston rod of the second single choice cylinder 224, the first catch 223 and the second catch 225 all can alternately stretch into storage bin hopper 21
Carrying out backgauge in blanking channel 211, wherein the distance between the first catch 223 and the second catch 225 is equal to the width of material 24.
Workflow and principle to pay-off of the present utility model are described in further detail below.
1, pan feeding state: with reference to Fig. 7, feeding servomotor 12 drives guide head 19 to rest at the left end of passage 20,
Second single choice cylinder 224 drives the second catch 225 to stretch in blanking channel 211, and the first single choice cylinder 222 drives the first catch
223 leave blanking channel 211, and a material 24 between the first catch 223 and the second catch 225 drops and enters guide through hole
In 201;
2, feeding waiting state: feeding waiting state is one-level feeding state, with reference to Fig. 8, feeding servomotor 12 works
Drive guide head 19 to move to chuck 23 direction thus promote material 24 to move to chuck 23 direction, when material 24 is pushed to folder
Time at the left side of 23, feeding servomotor 12 quits work, and now material 24 rests on and waits at the left side of chuck 23;
This one-level feeding process is to carry out in the Digit Control Machine Tool course of processing simultaneously, is not take up time process-cycle, the most greatly saves
About time of feeding;
3, feeding puts in place and discharging state: feeding puts in place and discharging state is two grades of feeding states, with reference to Fig. 9, works as chuck
After material 24 at 23 is processed, feeding servomotor 12 task driven guide head 19 continue to move to chuck 23 direction from
And continue to press on material 24 and move to chuck 23 direction, material 24 also promotes the workpiece in front to move simultaneously, the work in last front
Part is pushed out and drops in dump skip, and material 24 is pushed to position simultaneously.
So circulate according to above-mentioned steps.
To sum up, pay-off of the present utility model, it can carry out discharging and feeding automatically, and feeding also realizes while putting in place
Discharging, therefore material switch speed is fast, improves production efficiency;Manually timing is only needed to be positioned in storage bin hopper by material
Realize long-time processing the most automatically, therefore save artificial, reduce cost of labor;Automatically discharging and feeding are carried out, automatically
Change level is high, is advantageously implemented automated production;Lead feeding process smooth and easy stable, do not have the abnormal conditions of jam, therefore
Leading feeding stability might as well.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all at this
Within the spirit of utility model and principle, any modification, equivalent substitution and improvement etc. made, as three station feedings, four stations send
Material, five station feedings or N station feeding, within should be included in protection domain of the present utility model.
