Description
Technical field:
The present invention relates to mechanical technique, is the cam gear in a kind of mechanical drive, specifically, is a kind of frequency division ring form series voltage stack driven electronic cam train.
Background technology:
Cam mechanism because of its output movement can in very large range artificially select light, spin in the engineering and use in a large number.But cam mechanism belongs to the higher pair in the mechanical drive, and wearing and tearing are big, and vibration is big, and transmission accuracy is not high.And cam profile be in case after make determining, the characteristics of motion as changing, must manufacture and design cam with regard to unique expression in addition, and the cost height lacks flexible.Occurred electronic cam train at present, useful in the world servomotor directly drives rotating shaft, and by appointment requirement programming Control, rotating shaft drives a cover mechanism and realizes linear displacement to the operation of servomotor.This patent proposes a kind of complete novel electronic cam gear, utilizes piezoelectric pile can realize the accurately flexible principle of trace under electro ultrafiltration, designs frequency division ring form series voltage stack driven electronic cam train.
Summary of the invention:
The purpose of this invention is to provide a kind of no driving member, simple in structure, can change the voltage and the frequency of each piezoelectric pile input current as required, thus flexible change output movement; Strengthened the mechanical motion output quantity; Be not subjected to the effect of shearing force, moment of flexure, moment of torsion when guaranteeing piezoelectric pile work, improved the frequency division ring form series voltage stack driven electronic cam train of functional reliability.
Technical solution of the present invention is: a kind of frequency division ring form series voltage stack driven electronic cam train, it is characterized in that: one group of equally distributed ringwise piezoelectric ceramics heap is arranged, the lower end and the base 1 of first piezoelectric ceramics heap wherein are fixedly connected, and the guide pin bushing that can slide on guide pillar is housed; First piezoelectric ceramics heap links to each other by last gusset with adjacent piezoelectric ceramics heap, and adjacent piezoelectric ceramics also has guide pin bushing, and links to each other by second line of a couplet fishplate bar with adjacent again piezoelectric ceramics heap, according to this, each piezoelectric ceramics pile by about gusset be cascaded; On the guide pin bushing of last piezoelectric ceramics heap, add the mechanical shift take-off lever.
Each piezoelectric ceramics heap described in the present invention is applied with the simple-sinusoidal voltage of selected frequency respectively, and the total displacement after the dilatation displacement of each piezoelectric ceramics heap is the linear superposition of each piezoelectric ceramics heap displacement, is the superposition of finite term fourier series.Each piezoelectric ceramics heap all has electrical control lines, and electrical control lines is connected with converter plant.
Beneficial effect of the present invention is: compare with traditional cam mechanism, directly produce displacement of the lines with piezoelectric pile, as output movement, no driving member, simple in structure, can change the voltage and the frequency of each piezoelectric pile input current as required, thus flexible change output movement; Each piezoelectric pile annular series connection, the stroke linear superposition has strengthened the mechanical motion output quantity; At last, adopt common guide pillar, be not subjected to the effect of shearing force, moment of flexure, moment of torsion when guaranteeing piezoelectric pile work, improved functional reliability.Patent device is expected to substitute the mechanical type cam mechanism in certain engineering field, realizes the electronization and the flexibility of mechanical shift output.
The present invention is further illustrated below in conjunction with drawings and Examples:
Description of drawings:
Fig. 1 is an of the present invention kind of frequency division ring form series voltage stack driven electronic cam train;
Fig. 2 is the stretch-out view around guide pillar of Fig. 1.
Embodiment:
Fig. 1, Fig. 2 have described one embodiment of the present of invention jointly.In this routine Fig. 1, several piezoelectric ceramics heaps 1.1 (arriving N5 for N1 among the figure) evenly distribute ringwise, and wherein lower end and the base among Fig. 2 2.1 of piezoelectric ceramics heap N1 are fixedly connected.Piezoelectric ceramics heap N1 is equipped with guide pin bushing, and guide pin bushing 2.2 can be gone up at guide pillar 2.4 (being expressed as 1.1 among Fig. 1) and slide.Piezoelectric ceramics heap N1 piles N2 with adjacent piezoelectric ceramics and links to each other by last gusset 2.3.By that analogy, piezoelectric ceramics heap N2 also has guide pin bushing, can slide on guide pillar 2.4, and piezoelectric ceramics heap N2 links to each other by second line of a couplet fishplate bar 2.6 with piezoelectric ceramics heap N3.To N5,5 piezoelectric ceramics heaps are cascaded by gusset up and down from piezoelectric ceramics heap N1.Install the mechanical shift take-off lever additional on the guide pin bushing of piezoelectric ceramics heap N5, concentrated expression has reflected total mechanical shift output quantity.To N5, electrical control lines 1.4 is arranged all at each piezoelectric ceramics heap N1, electrical control lines 1.4 links to each other with frequency converter (not drawing among the figure).Frequency converter is made programming Control, and electric controller just applies the voltage of different frequency, different amplitudes to each piezoelectric ceramics heap.On the displacement take-off lever, just produce that each piezoelectric ceramics heap linear superposition forms, satisfy the total displacement that special exercise requires.Because the stroke of piezoelectric ceramics heap is very accurate, and hysteresis is minimum, load-bearing capacity is very big, so the needs in the light textile engineering are satisfied in the displacement of displacement take-off lever 2.4 outputs, as knitting needle accurately send pin, camera accurately transfer silk, the paper precision positioning of printing automatically.
