Embodiment 1, referring to figs. 1 to Fig. 6
As shown in figure 1, a kind of two-way feed device provided by the invention, including cross feed device 100 and length feed
Device 200.
Cross feed device 100 includes the first pedestal 110, the second pedestal 120, the first timing belt 130, the second timing belt
140 lateral driver devices 150 moved with the first timing belt 130 of driving and the second timing belt 140.
Wherein, as shown in Fig. 2 the first pedestal 110 includes casing 111 and case lid 112, casing 111 is the length of upper opening
Square structure, the first timing belt 130, can be by the first timing belts after case lid 112 is fastened on casing 111 in casing 111
130 closings.Two synchronous pulleys 160 are additionally provided with first pedestal 110, two synchronous pulleys 160 are connected by the first timing belt 130
Connect.One of synchronous pulley 160 is fixed on the bottom of casing 111 by support base 170, the synchronous pulley 160 and support base 170
Connected by central axis.Another synchronous pulley 160 is connected with lateral driver device 150, i.e. the energy of lateral driver device 150
The synchronous pulley 160 is enough driven to rotate, so as to drive the first timing belt 130 to move.It is adjustable by the position for changing support base 170
Centre-to-centre spacing between whole two synchronous pulleys 160.
Second pedestal 120 is identical with the structure of the first pedestal 110.Second timing belt 140 is arranged in the second pedestal 120, its
Specific installation form is identical with the first timing belt 130.
The motion of first timing belt 130 and the second timing belt 140 is completed by lateral driver device 150, laterally driven dress
It can be directly servomotor to put 150, i.e., 160 external servomotors of a synchronous pulley in the first pedestal 110, second
160 external servomotors of a synchronous pulley in pedestal 120.That is, the first timing belt 130 and the second timing belt
140 motion is by two Serve Motor Controls.But this type of drive easily causes the first timing belt 130 and the second timing belt
Difference, the feeding for ultimately resulting in cross feed device 100 are unstable for 140 movement velocitys.
Therefore, in this embodiment, it is preferred that, as shown in figure 3, lateral driver device 150 includes the 3rd pedestal 151, double
The drive device 153 of output shaft 152 and second, the second drive device 153 are servomotor, the pedestal 151 of double output shaft 152 and the 3rd
Rotation connection, one end of double output shaft 152 are connected with a synchronous pulley 160 in the first pedestal 110, double output shaft 152
The other end is connected with a synchronous pulley 160 in the second pedestal 120.

Second timing belt 140 moves.Drive the output shaft of the servomotor of the rotation of double output shaft 152 can be directly same with double output shaft 152
Axis connection, i.e. double output shaft 152 are directly connected by shaft coupling with servomotor.But this connected mode can cause double output shaft
There are larger difference, i.e. double output shaft 152 with the moment of torsion suffered by the first timing belt 130 and the link position of the second timing belt 140 on 152
One end away from servomotor farther out twists one end nearer away from servomotor of relative double output shaft 152, it is impossible to ensures
First timing belt 130 is identical with the transient motion speed of the second timing belt 140.Therefore, in this embodiment, it is preferred that, it will watch
The centre position that motor is arranged on the axis direction of double output shaft 152 is taken, servomotor passes through a pair of conical gears 154 and lose-lose
Shaft 152 connects, i.e. the output shaft of servomotor and the right angle setting of double output shaft 152.
The servomotor that driving double output shaft 152 rotates is also secured on the 3rd pedestal 151, and the 3rd pedestal 151 plays solid
Determine the effect of double output shaft 152 and servomotor, the 3rd pedestal 151 can be arbitrary shape.In the present embodiment, to ensure servo
3rd pedestal 151 by external interference, is not arranged to shell structure, the 3rd pedestal by the transmission accuracy of motor and double output shaft 152
151 include matrix 1511 and lid 1512, and matrix 1511 is the rectangular parallelepiped structure of upper opening, and lid 1512 is fastened on matrix
Enclosed construction is formed on 1511.After double output shaft 152 is rotatablely connected with matrix 1511, the main body of double output shaft 152 is located at matrix
In 1511, the both ends of upper double output shaft 152 are located at outside matrix 1511, and the part that the both ends of double output shaft 152 are stretched out is used for and first
The timing belt 140 of timing belt 130 and second connects.Matrix 1511 is provided with the fixed seat 1513 for being used for fixing servomotor, fixed
Seat 1513 is arranged on the centre position of matrix 1511.
In addition, double output shaft 152 can be an overall major axis, can also more short axles compositions.In view of slender axles
Processing is more difficult, in the present embodiment, it is preferable that double output shaft 152 is made up of more short axles.Double output shaft 152 includes first
Short axle 1521, the short axle 1523 of jackshaft 1522 and second, the first short axle 1521 is identical with the length of the second short axle 1523, and first is short
The short axle 1523 of axle 1521 and second is connected by elastic dowel pin shaft coupling 1524 with jackshaft 1522.In installation process, in
Countershaft 1522 is connected by a pair of conical gears 154 with servomotor, and the first short axle 1521 passes through synchronous with the first timing belt 130
Belt wheel 160 is connected, and the second short axle 1523 is connected with the second timing belt 140 by synchronous pulley 160.
As shown in figure 4, longitudinal feeding device 200 includes the first sliding block 220 of the first guide rail 210, the first sliding block 220 and driving
The first driving means 230 of motion, the first sliding block 220 are slidably connected with the first guide rail 210.
As shown in figure 5, the first sliding block 220 includes first connecting portion 221, the connecting portion 223 of second connecting portion 222 and the 3rd,
First connecting portion 221, second is connected and the 3rd connecting portion 223 is sequentially connected, and the connecting portion 223 of first connecting portion 221 and the 3rd is equal
It is vertical with second connecting portion 222.First connecting portion 221 is provided with the first gliding mass 2211, and the lower surface of second connecting portion 222 is provided with
Second gliding mass 2221, the upper surface of second connecting portion 222 are provided with perpendicular connecting plate 2222, set on the 3rd connecting portion 223
There is the 3rd gliding mass 2231.The left surface of second guide rail 260 offers the first chute 211, and the upper surface of the first guide rail 210 offers
Two chutes 212, the right flank of the second guide rail 260 offer the 3rd chute 213.First gliding mass 2211 is stuck in the first chute 211,
Two gliding masses 2221 are stuck in the second chute 212, the 3rd gliding mass 2231 just realizes the first sliding block 220 and after being stuck in the 3rd chute 213
One guide rail 210 is slidably connected.During relative first guide rail 210 of first sliding block 220 slides, the first sliding block 220 will not be with
First guide rail 210 departs from.
The first driving means 230 for driving the first sliding block 220 to move include ball-screw 231 and servomotor 232, servo
The output shaft of motor 232 is connected with ball-screw 231 by shaft coupling.Ball-screw 231 passes through 210 turns of bearing and the first guide rail
Dynamic connection.The screwed hole being engaged with ball-screw 231, ball-screw are provided with the second gliding mass 2221 in first sliding block 220
231 are located in the second gliding mass 2221.
In installation process, 140 equal lateral arrangement of the first timing belt 130 and the second timing belt, 210 longitudinal cloth of the first guide rail
Put, one end of the first guide rail 210 is arranged on the first timing belt 130, and the other end of the first guide rail 210 is arranged on the second timing belt
On 140.When servomotor 232 drives ball-screw 231 to rotate, the first sliding block 220 will be transported along the length direction of the first guide rail 210
It is dynamic.So as to realize the lengthwise movement of the first sliding block 220.
First sliding block 220 is precision-fit with ball-screw 231, and extraneous factor is easy to influence both fit precision,
