Description
Technical field
The present invention relates to a kind of abrasive band deviation system for abrasive band grinding machine, particularly about a kind of abrasive band deviation system for abrasive band grinding machine with online real-time automatic deflection adjusting function.
Background technology
Grinding is the process of workpiece being processed with emery wheel, abrasive band or other grinding tool (as oilstone, grinding segment, bistrique and abrasive pastes etc.).Sbrasive belt grinding is as a kind of novel coated grinding process that the title of " universal grinding " and " cold conditions grinding " is arranged in the material surface Precision Machining, it is a kind of high efficiency, low cost, multiduty grinding new method, and it far surpasses conventional wheel grinding technology for the adaptability and the flexibility of various materials and Shape Parts processing.
Use in the milling drum system of sbrasive belt grinding, the tuningout in abrasive band is the content that needs are considered emphatically, its task is to correct the skew of abrasive band on contact wheel of rotation at a high speed, makes abrasive band centering guaranteeing grinding accuracy, and the danger that comes off when avoiding the abrasive band side-play amount excessive.The general method that adopts is to use the tuningout scheme of manual adjusting deviation device, this method is that the adjusting deviation device that can regulate pendulum angle is installed on milling drum, when the operator observes the abrasive band skew, manually change tuningout wheel pendulum angle, thereby realize the tuningout process of abrasive belt wheel.But this method needs operator's manual adjustments, consumes human resources, simultaneously inefficiency.This method also depends on operator's experience and operation skill in addition, and the uniformity of real-time and adjusting and precision are not high, and may the danger that the abrasive band comes off take place owing to the operations of operators error.
Summary of the invention
At the problems referred to above, the purpose of this invention is to provide a kind of belt grinding machine abrasive band automatic deflection adjusting system that can online real-time automatic deflection adjusting.
For achieving the above object, the present invention is by the following technical solutions: a kind of belt grinding machine abrasive band automatic deflection adjusting system, it comprises automatic detection device, automatically deviation-adjusting device, abrasive band and control system, described automatic detection device comprises a fixedly connected central shaft, one is connected centre wheel on the central shaft by bearing, one left side, the right detection taken turns the both sides that are installed in described centre wheel respectively by coaxial bearing, on the two ends of a described central shaft difference fixedly connected one and a left side, a right left side of detecting wheel outer face correspondence, right sensor, a described left side, the output of right sensor connects described control system; Described automatically deviation-adjusting device comprises the tuningout wheel that contacts with described abrasive band, connects described ball-screw, decelerating step motor, a plurality of kinematic pairs and the one group of connecting rod that connects each kinematic pair.
The present invention is owing to take above technical scheme, it has the following advantages: 1, the present invention is owing to be provided with left and right detection wheel with the centre wheel that drives the abrasive band is coaxial, and be provided with left and right sensor, therefore when skew takes place in the abrasive band, the detection wheel that can drive the offset direction rotates, and by the sensor sensing of this side, and be transferred to control system, thus realized detecting automatically with in real time to the abrasive band shift state.2, the present invention is because to have adopted a cover motion principle be that known single closed loop space mechanism carries out online real-time tuningout, so technology maturation, tuningout precision height, and high conformity installs also very convenient.The full-automatic deviation system of the present invention need not artificial participation, has improved operating efficiency, and is safe and reliable, and it can be widely used in the various sbrasive belt grinding processing.

The specific embodiment
Below in conjunction with drawings and Examples, the present invention is described in detail.
As shown in Figure 1, the present invention includes automatic detection device 1, automatically deviation-adjusting device 2, abrasive band 3 and control system.Control system is a common PLC system, and it also controls other function of milling drum except control automatic detection device 1 and automatically deviation-adjusting device 2.
When milling drum abrasive band 3 ran well, abrasive band 3 was positioned on the centre wheel 11, drove centre wheel 11 and rotated, left and right detection wheel 13,14 equal transfixions.When abrasive band 3 occurrence positions are offset, a left side be will touch and wheel 13 or the right wheel 14 that detects detected, and drive its rotation, left sensor 15 or right sensor 16 that this rotation can be rotated a side detect, and this switching value signal in time is transferred to control system, thereby realize detecting automatically with in real time to abrasive band 3 shift state.
As shown in Figure 1 and Figure 2, automatically deviation-adjusting device 2 of the present invention is that a motion principle is a known single closed loop space mechanism, and it comprises tuningout wheel 21, ball-screw 22, decelerating step motor 23, a plurality of kinematic pair A, B, C, D, E and the one group of connecting rod 24,25,26 that connects each kinematic pair.
During automatic deflection adjusting, drive ball-screw 22 by decelerating step motor 23 and turn an angle, make the moving up and down of kinematic pair B that connects ball-screw 22 drive 21 swings of tuningout wheel, reach the purpose of abrasive band 3 tuningouts.When wherein tuningout wheel 21 is swung, connecting rod 24 on the tuningout wheel 21 can be around kinematic pair A swing, this swing causes that connecting rod 25 produces around the swing of kinematic pair B and moves up and down, this swing and move up and down can by kinematic pair D sliding up and down and bar 26 absorbs around the rotation of kinematic pair E.
As shown in Figure 3, the flow process during the invention process automatic deflection adjusting is as follows:
When 1, abrasive band 3 runs well, be in centre wheel 11 centers, neither taking back does not take over yet.When abrasive band 3 is offset left, can contact a left side and detect wheel 13, can contact the right wheel 14 that detects to the right when being offset, after abrasive band 3 touched and detects wheel, detecting wheel will be begun rotation by drive;
If 2 left sides are detected wheel 13 and rotated and will be detected by left sensor 15, and are transferred to control system,, and be transferred to control system if the right wheel 14 that detects rotates and will be detected by right sensor 16;
When 3, control system receives sensor signal, will be according to the yawing moment in abrasive band 3, startup decelerating step motor 23 is just being changeed or is being reversed;
4, the rotation of decelerating step motor 23 will drive the swing position that single closed loop space mechanism changes tuningout wheel 21, thereby cause the skew of 3 positions, abrasive band;
5, when abrasive band 3 was adjusted to the detection wheel that breaks away from the generation skew, this side senser detection signal stopped, and control system stops the rotation of decelerating step motor 23, thereby tuningout wheel 21 stops swinging, and centre wheel 11 centers are got back in abrasive band 3.
Above-mentioned explanation to embodiment just is used for helping to understand method of the present invention and core concept thereof, and should not be construed as limitation of the present invention, and every various equivalent transformations that carry out on basis of the present invention all should not got rid of outside protection scope of the present invention.
