The accompanying drawing explanation
below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Fig. 1 is structural representation of the present invention;
Fig. 2 is control schematic diagram of the present invention;
Mark in figure, 1 is left frame, and 2 is right frame, and 3 is back shaft, and 4 is linear bearing, and 5 is left socle, and 6 is right support, and 7 is vertex of a cone head, and 8 is the material pipe, and 9 is the feed screw nut, and 10 is screw mandrel, and 11 is motor, and 12 is scrambler, and 13 is cylinder.
Embodiment
Following non-limiting examples is for illustrating the present invention.
Embodiment: as depicted in figs. 1 and 2, a kind of shaftless material jacking mechanism with the wide addressing system of material, comprise left and right frame 1,2, this left and right frame 1,2 is provided with two horizontal back shafts 3, these back shaft 3 axle smooth surfaces, be socketed with four linear bearings 4 on it, linear bearing 4 can slide vertically on back shaft 3, and linear bearing 4 also is connected with respectively left socle 5 and right support 6.This left and right support 5,6 is the del structure, is provided with vertex of a cone head 7 on its structure, is placed with material pipe 8 between two vertex of a cone heads 7.
Also be connected with feed screw nut 9 on left socle 5, feed screw nut 9 coordinates with being with externally threaded screw mandrel 10 machineries, this screw mandrel 10 by bearing fit on left frame 1, and with back shaft 3 keeping parallelisms, the one end is connected with motor 11 by belt pulley, this motor 11 is fixedly connected on left frame 1, at the end of motor 11, also is provided with scrambler 12.
Also be connected with cylinder 13 on right support 6, the through hole that the piston rod of cylinder 13 is provided with through right support 6, be fixed on right frame 2.
As optimal way, this motor 11, scrambler 12 are connected by signal with the controller that the wide addressing system of this material is provided with respectively, this cylinder 13 connects Pneumatic valve by pipeline, and this Pneumatic valve is connected by signal with controller, and controller is connected by signal with man-machine interface; This controller is the PLC controller, and this motor is stepper motor, and this scrambler is incremental encoder, and this cylinder is the double-acting type cylinder.
The course of work of the present invention is: before the wide addressing system of this material is used, the relative position the unknown on back shaft 3 of left socle 5 and right support 6, therefore need to first determine the position of left socle 5, then take left socle 5 as benchmark, determine the relative position of left and right 5,6 supports.This controller sends control signal to motor 11, motor 11 drives screw mandrel 10 rotations by belt pulley, screw mandrel 10 drives left socle 5 by feed screw nut 9 and make relative traveling priority on back shaft 3, when left socle 3 is gone to limit on the right-right-hand limit position, controller sends reverse control signal to motor 11, makes left socle 5 oppositely move to limit on the left position; In this process, the scrambler 12 of motor 11 rear ends also and then rotates, and sends count pulse to controller, and the range data of controller movement on back shaft according to count pulse quantity and left socle 5, can determine the now position of left socle 5 on back shaft 3.Then according to the specification data of expecting pipe 8, defeated feeding pipe 8 width parameters on man-machine interface, controller sends control signal to Pneumatic valve, and Pneumatic valve provides the control source of the gas to cylinder 13, cylinder 13 promotes right support 6 and relatively moves left on back shaft 3, and right support 6 is close to left socle 5.When vertex of a cone head 7 clamps material pipe 8, right support 6 stops mobile, and left socle 5 and right support 6 interaction fixed supports play material pipe 8.
Because scrambler 12 can be converted into count pulse to the rotation angle displacement, each pitch of the upper outside threaded portion of screw mandrel 10 is also determined value, and by certain conversion relation, the rapid pulse of using tricks rushes the straight-line displacement that quantitaes left socle 5 moves on back shaft 3.For expressing clearly this conversion relation, especially exemplified by example, illustrate: establish left socle 5 when limit on the left position, this encoder to count pulse is 1000, motor 11 electric rotation, when left socle 5 moves right to limit on the right-right-hand limit position, this encoder to count pulse is 10000; Calculate left socle 5 these sections by meter and move distance for 500mm, use again (10000-1000): 500=18, numerical value 18 means that the every generation 1 mm displacement of left socle 5 just needs 18 count pulses, suppose that now count pulse is 2520, calculate 2520:18=140, numerical value 140 means that left socle 5 produces the 140mm displacement to the right.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any modifications of doing within the spirit and principles in the present invention, be equal to and replace and improvement etc., within all should being included in protection scope of the present invention.
