Abstract
The invention provides an online detecting monitoring system used for a precision machine tool relating to a computer-based automatic detecting and control system. The traditional detecting method relates to off-line detecting and in-situ detecting both of which are static detecting methods carried through under a state that the lathe is stopped; the detecting result and the machining quality can be affected as the difference of environment and clamping a work-piece again. The invention adopts a microscope digital camera technology and a rectilinear sensing camera technology. The signal detected can be compared, amplified and outputted to a terminal control macro-feeding structure in a programmable computer industry controller to adjust the feeding flow and the rotating speed of a motor to reach the goal of precise machining. The invention has the beneficial effects of high automation degree, compact structure and convenient operation.
Description
Technical field
The present invention relates to the computer automatic-detection control field, especially the detection of the precision machine tool in the machining is controlled.
Background technology
Traditional detection means is divided into offline inspection and detection on the throne, all under the lathe halted state, carries out, and be a kind of static detection method, if workpiece sensing is defective, will cause because of clamping again, the error that causes of tool setting again.Offline inspection, detection on the throne are owing to the difference of testing environment also has a significant impact testing result.At existing JVC full-automatic video measuring instrument, can only be as Static Detection, or the detection of autonomous system.Because the lathe geometric error causes the influence that machining accuracy is produced; The error that the main shaft thermal deformation produces during the lathe long-term work; The influence of processing parts self-deformation in process; The alignment error of anchor clamps; When anchor clamps are installed to the card compressive strain of part; The error of anchor clamps self; Process tool uses the back because the error that wearing and tearing cause long-term.This all can not carry out error compensation to the independent detection system, has limited precision machined needs to a great extent.
Summary of the invention
Purpose of the present invention can not only be implemented online detection for providing a kind of in process, and can constitute the precision machine tool on-line detecting system of the error compensation of workpiece with control system.
The technical scheme that realizes the foregoing invention purpose is: on the motion bracket of lathe and column a plurality of video measuring heads are housed, length gauge, temperature sensor, the corresponding processing work information that tracking is measured is delivered to respectively on the control system programmable calculator industrial control unit (ICU), after handling, control system decodes corresponding signal, control horizontal servomotor driver module respectively, servo longitudinal motor drive block and main axle servo motor drive block, laterally servomotor driver module, servo longitudinal motor drive block and main axle servo motor drive block start horizontal servomotor, servo longitudinal motor and main axle servo motor are regulated and machined parameters automatically.
Different angles at motion bracket are provided with a plurality of video measuring heads, are provided with the plane length gauge of beating on motion bracket, are provided with the circular runout length gauge on column.
The present invention makes full use of micro-digital vedio recording technology and straight line sensing technology, adopting micro-digital camera head to carry out dynamic machining follows the tracks of, on the scale display, reflect the amount of feeding, processing dimension, cutter operating mode at any time, the data that obtain by workpiece each point position and micro-digital camera head compare processing, can reflect online shaped position precision, the surface roughness of workpiece on the scale display at any time.Micro-digital vedio recording technology is in the most effective means of X-ray inspection X in Precision Machining and the ultraprecise processing, because of control system adopts the programmable calculator industrial control unit (ICU), by relatively amplifying, export detected signal to terminal control is little advances mechanism, main axle servo motor driver; Regulate the amount of feeding, motor speed, with the shaped position precision that reaches surface of the work, the error compensation of roughness.In Precision Machining and ultraprecise processing, monitor the operation conditions of lathe at any time, and in time regulate duty parameter, carry out the operating mode compensation.The variations in temperature source mainly is reflected in variation of ambient temperature, the variations in temperature that the lathe frictional heat causes, lathe frictional heat source appear at the friction width of cloth (generally not adopting gear transmission chain in Precision Machining and super-precision machine tools) between the bearing friction width of cloth, the rail friction width of cloth, leading screw the friction width of cloth, cutter and the workpiece usually.By variations in temperature, cause that each parts of support lathe, movement parts material stretch, and destroy the lathe nominal situation.Guarantee environment constant temperature, the rub constant temperature of the width of cloth respectively.Error compensation is the means of most economical, modern the easiest solution.Utilize the infrared emanation sensor advantage of precision height, good stability, dependable performance, thermal radiation sensor as the each point frictional heat, the signal that sensor is monitored inputs to control system, by relatively amplifying, export terminal to, control little advance mechanism, main axle servo motor driver, regulate the amount of feeding, motor speed, with the precision that reaches surface of the work, the error compensation of roughness.
The present invention has realized in process implementing to detect, and grasps the mismachining tolerance value and the development trend thereof of workpiece at any time, is input to control system and controls then littlely to enter mechanism and adjust, compensate, and reaches Precision Machining and superlinishing purpose.
The present invention has the automaticity height, compact conformation, easy to operate beneficial effect.

Fig. 1 is used for the structure of the on-line detecting system of precision machine tool and forms schematic diagram for the present invention
Fig. 2 is the control system structured flowchart
The specific embodiment
Now the present invention program is described further by the following example.
As Fig. 1-shown in Figure 2: in the process of feed bracket 1 motion, driving motion bracket 3 moves together, the length gauge 5, the video measuring head 6 that are arranged on the motion bracket are aimed at processed point simultaneously, follow the tracks of and detect the processing operating mode, change along with work piece 9 longitudinal sizes, hoist cylinder 2 is followed processed point by control system and is regulated lifting distance at any time automatically, guarantees that tested pilot is in optimum state.Ball-screw 4 is provided with in order to reduce friction.Different angles are provided with three video measuring heads 6 on the motion bracket, can detect operating mode size, the roughness of work piece 9 in different angles.Be arranged on the plane that length gauge 5 on the motion bracket can detect workpiece 9 and beat, the length gauge 11 that is arranged on the column 10 is to be used for detecting workpiece 9 flatnesses and circular runout.The on-line dynamic balancing head 7 that is arranged on the dynamic balancing support 8 can be according to the dynamic balancing of different workpiece 9 automatic adjustment movement parts.For control system, pass to control system by video measuring head, length gauge, the detected signal of temperature sensor, the programmable calculator industrial control unit (ICU) is after control system is handled, decode unlike signal, pass to horizontal servomotor driving, servo longitudinal motor drive block, main axle servo motor drive block respectively, and then start horizontal servomotor, servo longitudinal motor, main axle servo motor, and regulate machined parameters automatically, make work piece be in optimum state.Because of being implements to detect in process, grasp mismachining tolerance value and development trend at any time, and carry out error compensation control.
