Analyze known, the present invention can realize self-feeding, and a people can operate multiple stage simultaneously, improves operating efficiency, reduces labour intensity.Meanwhile, Workpiece length error can also be reduced, bring benefit, and only need common workman to operate.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in further details.
As shown in Fig. 1, Fig. 3, Fig. 4, it is substantially identical and (arrange elevating mechanism without the directive wheel 10-17 of driving mechanism, directive wheel 6-9 that structure is substantially identical that the embodiment of the present invention comprises driving wheel 1-5, structure, realize substrate hold-down function downward or upward, such as directive wheel 8), driving wheel motor 25, cylinder 19, saw blade motor 20, saw blade 23, first limit switch 24, second limit switch 21, the 3rd limit switch 22, cylinder 27, cylinder 29, fixture 30.
Specifically, as shown in Figure 1 and Figure 2, driving wheel 1-5, directive wheel 10-17, directive wheel 6-9 be layout along a rectilinear direction and in double-decker, groove between so many directive wheel, driving wheel utilize provides a mobile platform for long tube 66, as shown in Figure 3, Figure 4, the driving wheel 1-5 in mobile platform then can drive long tube 66 to move.
The structure of each driving wheel 1-5 is substantially identical, and as shown in Figure 4, driving wheel motor 25 rotates for driving driving wheel 1, is connected between driving wheel 1 and the output shaft of driving wheel motor 25 by a major axis 26, and this major axis 26 is erected on a support movably.
As shown in Figure 3, Figure 4, the wheel elevating mechanism of the present embodiment is cylinder 27, cylinder 29 etc., multiple cylinder 27 is connected with the driving wheel 1-5 etc. being positioned at mobile platform upper strata, multiple cylinder 29 is connected by major axis 28 with the directive wheel 6-9 being positioned at mobile platform upper strata, be positioned at directive wheel 6-9 or the driving wheel 1-5 on upper strata to raise or to land, thus compress or unclamp long tube 66.When the piston rod of cylinder 27, cylinder 29 stretches out, long tube 66 is close in the landing of each corresponding driving wheel, directive wheel; During retraction, each corresponding driving wheel, directive wheel then raise, and leave long tube 66.
Fixture 30 is positioned at the middle part of mobile platform, for the long tube 66 that is fixedly clamped.
Saw blade 23 is positioned at above fixture 30, for cutting long tube 66.Saw blade motor 20 rotates for driving saw blade 23, and saw blade 23 is fixed on the output shaft of saw blade motor 20.Saw blade lifting mechanism is cylinder 19, and its piston rod is connected with saw blade motor 20, raises for driving saw blade motor 20 or lands.
In order to improve the automatization level of the embodiment of the present invention, the present embodiment also comprises the first limit switch 24, second limit switch 21, the 3rd limit switch 22.As shown in Figure 1 and Figure 2, the first limit switch 24 is positioned at the front end of mobile platform.In electrical connection, control planning, it is connected with driving wheel motor 25, fixture 30, cylinder 19, saw blade motor 20, when long tube 66 moves to the first limit switch 24, driving wheel motor 25 is out of service, fixture 30 clamps long tube 66, cylinder 19 drives that saw blade motor 20 is landed, saw blade motor 20 starts cutting long tube 66.
As shown in Figure 1, the second limit switch 21 is positioned at below saw blade motor 20, is connected with cylinder 19, and when saw blade motor 20 moves to the second limit switch 21, cylinder 19 starts to raise saw blade motor 20; 3rd limit switch 22 is positioned at above saw blade motor 20, is connected with cylinder 19, and when saw blade motor 20 moves to the 3rd limit switch 22, cylinder 19 is out of service.
In other embodiments, respectively taking turns elevating mechanism, saw blade lifting mechanism also can be oil cylinder, motor etc.
When applying the present embodiment, long tube 66 is put into mobile platform, driving wheel moves down is close to long tube 66 outer wall, long tube 66 is driven to move forward, when moving to the first limit switch 24, be the length of the long tube 66 of required cutting, when needs adjustment Len req, the position of mobile first limit switch 24.
After long tube 66 moves into place, decline such as saw blade 23 grade, starts to cut long tube 66, and the second limit switch 21, the 3rd limit switch 22 move up and down position for what control saw blade motor 20.
In sum, the present invention strictly can set the Cutting Length of long tube, and degree is high automatically, can reduce human cost, reduces labor strength.
As known by the technical knowledge, the present invention can be realized by other the embodiment not departing from its Spirit Essence or essential feature.Therefore, above-mentioned disclosed embodiment, with regard to each side, all just illustrates, is not only.Within the scope of the present invention all or be all included in the invention being equal to the change in scope of the present invention.
