The switch mechanism using at present generally only can be realized the switching (linear road and left bend or right bend) of two circulation lines, switch structure comprises track, track is arranged on movable frame, movable frame is arranged with roller, roller coordinates with the guide rail on fixed frame, utilize motor to drive movable frame to roll along guide rail, thereby the track on movable frame is moved to another position from a position, to realize the orbital docking with this position.The mode that adopts cylinder or electric cylinder and movable frame to be connected and directly to drive movable frame to roll along fixed frame guide rail, the precision of guiding is not high on the one hand, on the other hand, the piston rod of electricity cylinder or cylinder drives stroke limited, and can not realize optional position stop action, thereby can exist the orbital docking position on movable frame accurate not, automatic carriage fault rate in circuit handoff procedure is high.
Utility model content
The purpose of this utility model is: a kind of automatic carriage track switch shifter is provided, can realizes accurately the switching between track and track, improve merging precision between track and track.
For achieving the above object, the technical solution adopted in the utility model is: a kind of automatic carriage track switch shifter, comprise movable frame and fixed frame, on described movable frame, be provided with track, between described movable frame and fixed frame, be provided with linear guide portion, the direction that driver train drives movable frame to limit along linear guide portion with respect to fixed frame moves, described driver train comprises rack and pinion drive mechanism, and the length direction of the tooth bar in described rack and pinion drive mechanism is parallel with the moving direction of movable frame.
Compared with prior art, the technique effect that the utility model exists is: between movable frame and fixed frame, linear guide portion is set, the direction that movable frame is limited along linear guide portion moves, thereby can improve the guiding accuracy of movable frame, in the process that described movable frame moves along the tooth bar in rack and pinion drive mechanism, the stroke distances of tooth bar is far longer than the stroke of cylinder piston of the prior art on the one hand, the cooperation of wheel and rack can realize stopping arbitrarily of track on the other hand, this installs, and not only guiding accuracy is high, stroke distances is also large, can effectively guarantee the merging precision between track and track.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is front view of the present utility model;
Fig. 3 is the upward view of Fig. 2;
Fig. 4 is the left view of Fig. 2.
The specific embodiment
1 to Fig. 4 by reference to the accompanying drawings, and the utility model is further described:
A kind of automatic carriage track switch shifter, comprise movable frame 10 and fixed frame 30, on described movable frame 10, be provided with track, between described movable frame 10 and fixed frame 30, be provided with linear guide portion, the direction that driver train drives movable frame 10 to limit along linear guide portion with respect to fixed frame 30 moves, described driver train comprises rack and pinion drive mechanism, and the length direction of the tooth bar 51 in described rack and pinion drive mechanism is parallel with the moving direction of movable frame 10.
Shown in Fig. 1, between movable frame 10 and fixed frame 30, linear guide portion is set, the direction that movable frame 10 is limited along linear guide portion moves, thereby can improve the guiding accuracy of movable frame 10, in the process that described movable frame 10 moves along the tooth bar 51 in rack and pinion drive mechanism, the stroke distances of tooth bar 51 is far longer than the stroke of cylinder piston of the prior art on the one hand, the cooperation of wheel and rack 51 can realize stopping arbitrarily of track on the other hand, this installs, and not only guiding accuracy is high, stroke distances is also large, can effectively guarantee the merging precision between track and track.
Concrete, shown in Fig. 2, described linear guide portion comprises linear bearing 41 and the guide rail 42 cooperatively interacting, described linear bearing 41 is arranged on movable frame 10, described guide rail 42 is arranged on fixed frame 30, the length of described guide rail 42 is parallel with tooth bar 51 length directions, and this guide rail 42 is line slideway, and linear bearing 41 can be realized the directional tagging to fixed frame 30 accurately.
Further, tooth bar 51 in described rack and pinion drive mechanism is fixedly installed on movable frame 10, gear 52 is connected with motor 53 rotating shafts in driver train, motor 53 is fixedly installed on fixed frame 30, thereby electric machine rotation drives the movement of tooth bar 51, and then the direction that movable frame 10 is limited along linear guide portion with respect to fixed frame 30 moves.
Further, on described fixed frame 30, be provided with read write line 61, on described movable frame 10, be provided with coded scale 62, described coded scale 62 holdings are in the read-write end of read write line 61, and formation coordinates along the mobile of coded scale 62 length directions, the chi length direction of coded scale 62 is parallel with the length direction of tooth bar 51, with coded scale 62 and read write line 61, obtain the location information in movable frame 10 moving process, thereby make more accurately movable frame 10 arrive the position of setting, and then the track on movable frame 10 is docked with trapped orbit accurately.
