Abstract
The utility model provides a kind of Tai Wei mechanism of bearing force self-adaptative adjustment, problem to be solved is: when installing the lathe process Model For The Bush-axle Type Parts of fluid pressure type Tai Wei mechanism, when carrying out changing product, artificially must adjust platform tail bearing force, affect the production efficiency of production line.Main points of the present utility model are: it comprises platform tail and top, are toply fixed on platform urosome; Screw and platform tail are connected as a single entity, and screw is fixed on platform tail bottom, and screw coordinates with ball-screw, and servomotor drives ball-screw to rotate by shaft coupling.The beneficial effects of the utility model are: the bearing force of platform tail centre can adjust automatically according to part requirements, is particularly suitable in automatic assembly line, can shorten the productive temp of automatic assembly line, enhance productivity.
Description
Technical field
The utility model relates to a kind of platform tail of machining shaft cover parts lathe, and being specially platform tail bearing force can according to the servo station tail of the change self-adaptative adjustment of processing parts, to adapt to the automated production needs of lathe.
Background technology
The Tai Wei mechanism of current machining shaft cover parts lathe mainly contains two kinds of forms, and one is that overall by Driven by Hydraulic Cylinder, namely platform tail is arranged on the piston rod of hydraulic cylinder for whole tail, and platform urosome moves forward and backward with piston rod; Another kind is whole and trails slide plate dragging movement, and platform tail centre is telescoping structure, is sleeve oil cylinder, is moved forward and backward by HYDRAULIC CONTROL SYSTEM platform tail centre.The platform tail centre bearing force of these two kinds of versions provides by hydraulic coupling.When such lathe process Model For The Bush-axle Type Parts, when carrying out changing product, must hydraulic system pressure be artificially regulated to adjust platform tail bearing force, to adapt to different size part, so both add the non-cutting time of lathe process, the uniformity of part processing precision cannot be ensured again, in automatic assembly line, turn increase the productive temp of production line, affect the production efficiency of production line.
Summary of the invention
For improving working (machining) efficiency, the purpose of this utility model is to provide a kind of bearing force can the Tai Wei mechanism of self-adaptative adjustment, realize lathe process and change the part processing request according to different size in product process, platform tail can adjust automatically to the bearing force of part, ensures the reliability of lathe clamping different size part.
The technical solution adopted in the utility model is as follows: it comprises platform tail and top, it is characterized in that: be toply arranged on platform urosome; Ball-screw is arranged on platform tail bottom, and screw and platform tail are connected as a single entity, and screw coordinates with ball-screw, and servomotor drives ball-screw to rotate by shaft coupling.
The moment of torsion that the control servomotor of servomotor under its PMC control model exports, when the power suffered by servo motor output shaft end arrives setting moment of torsion, servomotor will stop the rotation, and keeps current output torque, and then the bearing force of holding station tail centre.
The beneficial effects of the utility model are: lathe is when processing different size part, the bearing force of platform tail centre can adjust automatically according to part requirements, remove the process of artificial adjustment bearing force from, reduce the non-cutting time of lathe process, ensure the machining accuracy of lathe, improve the automaticity of lathe, be particularly suitable in automatic assembly line, the productive temp of automatic assembly line can be shortened, enhance productivity.

Detailed description of the invention
It comprises platform tail and top 1, is toply arranged on platform urosome 2; Ball-screw 5 is arranged on platform tail bottom, and screw 4 and platform tail are connected as a single entity, and screw coordinates with ball-screw, and servomotor 7 drives ball-screw to rotate by shaft coupling 6.3 is guide rail slide blocks.
Job state: utilize the moment of torsion controlling functions under the PMC control model of servomotor, when the power suffered by servo motor output shaft end arrives setting moment of torsion, servomotor will stop the rotation, and keeps current output torque, and top 1 bearing force is controlled by servomotor output torque.When lathe needs to process different parts, host computer, logistics system or artificially issue task to lathe, lathe by the machined parameters issued calculate current want bearing force needed for processing parts and converse servomotor torque value write relevant parameter in, after clamping work pieces instruction received by lathe, platform tail will move to workpiece direction, until withstand after workpiece arrives presetting moment of torsion, send clamping settling signal, platform tail bearing force just ensures according to the output torque of the servomotor conversed.
