Embodiment
Fig. 1, Figure 2 shows that a kind of feed mechanism demonstration teaching aid, comprise the incomplete gear mechanism, RCCR shaft coupling, ball screw framework and the linear slide rail mechanism that are in transmission connection successively; Described incomplete gear mechanism is connected respectively on symmetrically arranged described RCCR shaft coupling by two output terminals of final drive shaft, the output terminal of described RCCR shaft coupling is connected on symmetrically arranged described ball screw framework by shaft coupling 9, and the output terminal of described ball screw framework is connected in symmetrically arranged described linear slide rail mechanism by web joint 12; On described ball screw framework, be provided with a plurality of approach switchs 16, on described web joint 12, be provided with feed table 15.During installation, approach switch 16 can be separately positioned in the end positions of screw rod 10.
Wherein, the engaged wheel 3 that above-mentioned incomplete gear mechanism mainly comprises driving wheel 2 and is meshed with it, one end of driving wheel 2 is provided with motor 1, and engaged wheel 3 is arranged on final drive shaft 7.On described driving wheel 2, be provided with several teeth, remainder is protruding locking circular arc; On described engaged wheel 3, be provided with several teeth, remainder is recessed locking circular arc.Above-mentioned RCCR shaft coupling comprises active rotating disk 5, right angle connecting rod 6 and the driven rotating disk 8 connecting successively; This active rotating disk 5, right angle connecting rod 6 and driven rotating disk 8 can form rotatable and mobile cylindrical pair.Ball screw framework comprises screw rod 10 and nut 11, and screw rod 10 and nut 11 form screw pair.Linear slide rail comprises guide rail 14 and slide block 13, and slide block 13 forms moving sets with guide rail 14.
Wherein, described active rotating disk 5 and driven rotating disk 6 are along being also respectively equipped with a plurality of round open-works on axis direction, two of right angle connecting rod 6 (can arrange according to actual needs a plurality of) is inserted into respectively in corresponding round open-work, so just can form the cylindrical pair that can rotate and move.
In addition, the guide rail 14 in the utility model is positioned at the inner side of screw rod 10, and is parallel to each other with screw rod 10.Final drive shaft 7 and screw rod 10 support by rolling bearing units assembly 4.
Principle of work: motor 1 starts, driving wheel 2 drives engaged wheel 3 to rotate, and according to the requirement of run duration and idle hours, makes the gear teeth that are meshed with driving wheel 2 on engaged wheel 3.When driving wheel 2 and engaged wheel 3 gear teeth enter engagement, the same with gear drive; When the protruding locking circular arc of driving wheel 2 and the recessed locking circular arc portion cooperation of engaged wheel 3, by locking circular arc location, make engaged wheel 3 static.Engaged wheel 3 is connected with final drive shaft 7, final drive shaft 7 and engaged wheel 3 synchronously rotate or stop, coaxial with final drive shaft 7, to be arranged on left and right sides active rotating disk 5 rotates, by right angle connecting rod 6, drive the driven rotating disk 8 of the left and right sides to rotate, driven rotating disk 8 drives again screw rod 10 to rotate, because the nut 11 of the left and right sides is connected with the slide block 13 being arranged on the linear slide rail on both sides respectively, two nuts 11 move as synchronous linear, drive two slide blocks 13 to do synchronous linear motion.Because feed table 15 is installed on web joint 12, so move with slide block 13.
Workpiece is put into feed table 15, and motor 1 starts, and by the mutual motion of each mechanism, transmits, feed table 15 moves forward, when incomplete gear mechanism enters idle hours, feed table 15 arrives first position, by mechanical hand (not shown in FIG.), takes off workpiece; Incomplete gear mechanism enters again run duration subsequently, and feed table 15 continues mobile, and when incomplete gear mechanism enters idle hours again, feed table 15 arrives second position, takes off workpiece again by mechanical hand, realizes thus multiple spot feeding.When feed table 15 enters rearmost position feeding, nut 11 reaches the limit of position, and when the sensitive surface of nut 11 and approach switch 16 is to operating distance, 16 pairs of motors 1 of approach switch send the steering order of shutdown.Mechanical hand takes off after workpiece, motor 1 reversion, and feed table 15 returns, and completes thus a working cycle.
Incomplete gear mechanism in the utility model is simple in structure, easy to manufacture, reliable operation, and engaged wheel run duration and rest time can change in a big way.But engaged wheel has greater impact when starting to enter engagement and depart from engagement, thus general only for low speed, underloading occasion.
Approach switch is a kind ofly without carrying out machinery with moving component, directly to contact and manipulable position switch, when the sensitive surface of object proximity switch arrives operating distance, do not need Mechanical Contact and apply any pressure to make switch motion, thereby provide steering order to drive unit.Approach switch is kind of a switching mode sensor (being noncontacting switch), and the characteristic of its existing travel switch, microswitch has sensing capabilities simultaneously, and reliable in action, stable performance, and frequency response is fast, long service life, antijamming capability is strong.Induction region when metal detection body approach switch, switch just can send rapidly electric instruction, accurate response goes out position and the stroke of motion, be used in general Stroke Control, convenience and the applicable ability to rugged surroundings that its positioning precision, operating frequency, serviceable life, installation are adjusted are that common mechanical formula travel switch institute is incomparable.
