Abstract
The utility model relates to a piezoelectric type final motion boring bar. The utility model is characterized in that the deforming boring bar uses integration structure similar to a lever type of an arc notch fulcrum; a driving element uses a piezoelectric element. The product has the advantage of simple structure, small volume, easy manufacturing and preparation, and convenient maintenance and installation.
Description
The utility model relates to a kind of piezoelectric type fine motion boring bar.
Engine is widely used in all trades and professions, in order to improve the efficient of engine, prolongs its life-span, and according to modern plunger designs theory, piston pin hole must be processed into special-shaped shapes such as loud-speaker.For processing profiled piston pin hole, need the boring bar of boring machine to carry out accurate fine motion.The precise jiggle boring bar that adopts at present all is to adopt centrifugal control drive-type or hydraulic drive type both at home and abroad, complicated in mechanical structure, and the installation and maintenance inconvenience, the processing of itself also needs ultraprecise processing, causes expensive price.
The purpose of this utility model is to provide a kind of novel piezoelectric simple in structure, that volume is little, processing and preparing is easy, convenient for installation and maintenance moving boring bar that declines.
The utility model is achieved in that deformable boring arm adopts the plan lever integral structure of arc gap fulcrum, and driving element adopts piezoelectric element, piezoelectric element be positioned at arc gap below.
Below in conjunction with drawings and Examples the utility model is described in detail.
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model user mode schematic diagram.
Consult shown in Fig. 1,2, deformable boring arm 1 adopts the plan lever integral structure of arc gap 2 fulcrums, and driving element adopts piezoelectric element 3, piezoelectric element 3 be positioned at arc gap 2 below.
The main shaft 4 of boring bar 1 with boring machine linked, and main shaft 4 rotations drive boring bar 1 and rotate simultaneously, if boring bar 1 invariant position and workpiece 5 move to boring cutter 6 vertically, then can process a cylindrical hole on workpiece; If boring bar moves up and down according to certain rules, then on workpiece, process a non-cylindrical hole; The rule difference that boring bar moves up and down then can obtain difform hole.
After piezoelectric element applies certain DC voltage, piezoelectric element can direct proportion ground elongation, then boring bar is understood the direct proportion displacement that moves up.By the voltage on the control piezoelectric element, it is upper and lower mobile just can to control boring bar easily.
The utlity model has following advantage: deformable boring arm adopts the arc gap fulcrum to intend thick stick The rod-type integral structure, simple in structure, be easy to processing and installation and maintenance.
