Abstract
The utility model discloses a control device of a boring machine. The control device of the boring machine comprises a vibrating sensor, a controller and a frequency converter, wherein the vibrating sensor is used for detecting vibration of a boring tool during a machining process; the controller determines whether resonance exists between the boring tool and a machined workpiece according to signals provided by the vibrating sensor and a rotating speed sensor, and regulates output rotating speed of a spindle motor; and the frequency converter receives signals from the controller and drives the spindle motor of the boring machine. According to the control device of the boring machine, the vibration condition of the boring tool is determined through the detection of the boring tool during the machining process, and control signals are output for regulation of the rotating speed of the spindle motor so as to avoid the resonance.
Description
Technical field
The utility model relates to the Machining Technology for Cutting field, is specifically related to a kind of control device of boring machine.
Background technology
Along with rapid development of science and technology, increasingly high to the quality and the performance demands of product.Improving the machining accuracy of product component, promptly is one of approach of dealing with problems.On the good hole of brill, carry out the essence hammer, this method has solved the low problem of boring machining accuracy, and concerning boring, the processing technology that very difficult usefulness is higher is come the further machining accuracy that improves.The traditional processing theory is not often considered processing work, and self vibration is to the influence of machining accuracy in process, and in fact the vibration of this workpiece self has caused the bottleneck that improves the workpiece machining accuracy.
Processing to the hole on the lathe is very general together operation, but after boring finished, majority need carry out right boring processing to the hole of being bored.Especially resemble the hole that perforated has relatively high expectations to axiality and roughness like this and carry out the processing of essence hammer,, more need carry out further smart clang processing it because of its complicated structure.And in the process of carrying out right boring, because in process, main shaft is rotating with fixing rotating speed always; Like this, the rotating speed of rotating shaft itself will produce the vibration of a fixed frequency, and because mostly the hammer stem on the main shaft is ferrous metal with the parts that added; Very approaching of their intrinsic frequency of being had itself; So in the process of parts processing, they very easily cause resonance, thereby; The right boring processing influence in the hole of being had relatively high expectations to axiality and roughness like this in hole especially perforated is very large, thereby is difficult to guarantee the right boring precision in hole.
Summary of the invention
To above-mentioned technical problem; The utility model provides a kind of control device of boring machine, and the utility model is judged the situation of the suffered vibration of boring cutter through boring cutter is detected in process; And export control signal the rotating speed of spindle motor is adjusted, avoid the generation of resonating.
The technical scheme that realizes the utility model purpose is following:
The control device of boring machine, the involving vibrations sensor is used for detecting the vibration that boring cutter receives in process; And
Controller, the signal that this controller provides according to vibrating sensor and speed probe is judged whether boring cutter and work piece resonate, and the output speed of spindle motor is adjusted; And
Frequency converter, this frequency converter receives the signal that comes from controller, and the boring spindle motor is driven.
Adopted such scheme, at first, the utility model is judged the situation of the suffered vibration of boring cutter through boring cutter is detected in process, and exports control signal the rotating speed of spindle motor is adjusted, and avoids the generation of resonating.Secondly; The utility model is through being provided with a plurality of alternative motor speed adjusted values, and when adjustment, controller is selected to adjust with the maximum speed adjusted value of current speed discrepancy; More reasonably rotating speed of motor is adjusted like this, also can be avoided the generation of resonating better.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the flow chart of the utility model;
In the accompanying drawing, 10 is vibrating sensor, and 20 is controller, and 30 is frequency converter, and 40 is speed probe.
The specific embodiment
With reference to Fig. 1, the control device of the boring machine of the utility model, involving vibrations sensor 10 is used for detecting the vibration that boring cutter receives in process; And
And the speed probe 40 that is electrically connected with controller, this speed probe is used to detect the output speed of boring spindle motor.
With reference to Fig. 2, the control method of the boring machine of the utility model may further comprise the steps:
Whether step 5, controller judge current tachometer value less than setting value according to the tachometer value that speed probe provides, if judged result for being, is then returned step 1, if judged result then gets into step 6 for not.
