Description

Draw material step transformation mechanism
The application is application number: 201110412999.7, the applying date: 2011.12.13, title: the divisional application of " drawing material step transformation mechanism ".
Technical field
The present invention relates to Machining Technology, adjust step pitch in real time specifically by step transformation mechanism, thus change the feeding step number on manufacturing line.
Background technology
Be a kind of common technology of field of machining apart from mapping device, mainly for the production of line draws material function, change corresponding step pitch according to actual needs.
After automatic production line occurs, draw normal needs on material process to change step pitch in real time at some, this operation needs manual operation usually, there is labour intensity large, the series of problems such as production efficiency is low, poor stability.Along with the development of technology, have corresponding step transformation mechanism at some production field, above problem is necessarily alleviated.But in the application process of reality, often there is problems such as shaking, step pitch transduced precision is low, wear and tear in machines is serious, have impact on product design, the continuity of manufacturing line and production efficiency.So step transformation mechanism haves much room for improvement.
Summary of the invention
The object of the present invention is to provide a kind of rational in infrastructure, what can realize the precise transformation of step pitch draws material step transformation mechanism.
Technical solution of the present invention is:
One draws material step transformation mechanism, it is characterized in that: comprise decentralizing device, single two step transform component and draw material spindle unit, wherein decentralizing device comprises connecting rod, and the upper end of connecting rod is connected with eccentric part by bearing, and the lower end of connecting rod walks transform component with list pair and is connected; Described list two step transform component comprises first, second cylinder, and the upper end of first, second cylinder is connected with the connecting rod of decentralizing device by attaching parts, and the lower end of first, second cylinder is connected with rocking bar; The described material spindle unit that draws comprises the rotating shaft be connected with single two rocking bar walking transform component, and rotating shaft loads the frame of fixation, rotating shaft is connected with the link gear rotation of rotating shaft being converted into straight-line motion.
Described connecting rod is divided into interconnective two sections.
Between described attaching parts and connecting rod, reinforced rib is set.
The present invention is rational in infrastructure, have employed the pioneering technologys such as eccentric stiffener, air-actuator, rotating shaft mechanism, further optimal design has been carried out to each composition mechanism in step transformation mechanism, thus define a kind of step pitch transduced precision, novel step transformation mechanism that contextual, production efficiency improve all greatly.
Compared with prior art concrete advantage of the present invention is:
(1) rational Design of Mechanical Structure, alleviates the problem such as shake, wearing and tearing that machine exists in operational process;
(2) adopt the master and slave control mechanism of two cylinder, step pitch transduced precision is higher, and speed is faster, and continuity is better;
(3) have employed rocker mechanism, rotating shaft and link gear, the rotary motion swinging by key drive rotating shaft of rocking bar, by key, the rotary motion of rotating shaft is passed to link gear again, finally be converted into by link gear the straight-line motion drawing material, improve the linear velocity of rotation, enhance the stability of mechanism.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described.
Fig. 1 is basic structure diagram of the present invention.
Fig. 2 is the basic structure diagram of eccentric part in the present invention.
Fig. 3 is the basic structure diagram of single two step transform component in the present invention.
Fig. 4 is the basic structure diagram drawing material spindle unit in the present invention.
Detailed description of the invention
One draws material step transformation mechanism, comprise decentralizing device 1, single two step transform component 2 and draw material spindle unit 3, wherein decentralizing device comprises connecting rod, and the upper end of connecting rod is connected with eccentric part by bearing, the lower end of connecting rod walks transform component with list pair and is connected, described connecting rod is divided into interconnective two sections 4,5, and seals with seal ring 6, nut, 7 pressuring actions, axle 8 coordinates with bearing 9, then is connected with eccentric part, and nut 11 plays the role of fastening; Spring shim 12 plays locking effect; Eccentric part is connected by bolt 14 by with parts 10,13.
Described list two step transform component comprises first, second cylinder 15,16, and the upper end of first, second cylinder is connected with the connecting rod 5 of decentralizing device by attaching parts, and the lower end of first, second cylinder is connected with rocking bar 17; The described material spindle unit that draws comprises the rotating shaft 19 be connected with single two rocking bar 17 walking transform component by key 18, by which, can obtain continuous, efficient rotation process.Rotating shaft loads the frame 20 of fixation, rotating shaft 19 is connected with the link gear 21 rotation of rotating shaft being converted into straight-line motion by key, improves stability and the linear velocity of rotation.
Reinforced rib 22 is set between described attaching parts and connecting rod 5.
