Description
Technical field
The present invention relates to a kind of use Tiny pore as the wide-belt sander Tiny pore abrasive band position detecting device of detection wide-belt sander abrasive band whether sideslip and control method, belong to wide-belt sander abrasive band controlling organization and manufacture field.
Background technology
CN102814716A, title " a kind of buffing machine abrasive band automatic deviation rectifying mechanism ", including infrared sensor, DC servo motor, eccentric, connecting rod, Worm and worm-wheel gearing and deviation correcting roller；Described infrared sensor, DC servo motor and Worm and worm-wheel gearing are each attached on buffing machine base plate；Described deviation correcting roller coaxial sleeve is on the worm screw of Worm and worm-wheel gearing, and is connected by bearing, makes deviation correcting roller energy on worm screw freely rotatable；Infrared sensor detection buffing machine abrasive band sideslip situation, and offset signals is passed to peripheral control unit；Described DC servo motor is by peripheral control unit control, and DC servo motor output shaft is coaxially connected with eccentric one end, and DC servo motor output shaft band movable eccentric wheel rotates；The described eccentric other end is connected with connecting rod one end bias, and when eccentric rotates, drivening rod swings, and connecting rod swing plane is vertical with eccentric axis；The connecting rod other end is fixed with swinging axle, and swinging axle axis is perpendicular to connecting rod swing plane, drives swinging axle to rotate during connecting rod swing；Described swinging axle is fixedly and coaxially connected with the worm gear of Worm and worm-wheel gearing.Its weak point: use photoswitch to detect position, abrasive band; output signal to controlling organization action and realize function; owing to sander is a kind of high efficiency grinding mode; produce substantial amounts of abrasive dust; machine internal medium is very poor; and the detection environment of photoswitch requirement is higher, therefore often occur because camera lens pollutes the disorderly closedown produced, have a strong impact on the normally use of machine.
Summary of the invention
Purpose of design: avoid the weak point in background technology, designs and a kind of uses Tiny pore as the wide-belt sander Tiny pore abrasive band position detecting device of detection wide-belt sander abrasive band whether sideslip and control method.
Design: in order to realize above-mentioned purpose of design.1, use Tiny pore as the design of detection wide-belt sander abrasive band whether sideslip, be one of the technical characteristic of the present invention.So purpose of design is: wide-belt sander is operationally, high speed rotating grinding is made in abrasive band on sanding head, simultaneously need to make axial swinging back and forth along contact roller, its effect is control band, chip removal, multiple effects such as improvement grinding status, in order to the swinging track in abrasive band is controlled in the range of needs, background technology generally uses photoswitch to detect position, abrasive band, the swing of sanding head is controlled by photoelectric output signal, but owing to sander is a kind of high efficiency grinding mode, substantial amounts of abrasive dust is produced during grinding, this grinding causes machine internal medium very poor, make to require that the photoswitch that detection environment is higher is usually in the contaminated state of Photoelectric Detection in the detection rectified a deviation in sander abrasive band, so often resulting in disorderly closedown, have a strong impact on the normal use of sander.The application uses Tiny pore as detection wide-belt sander abrasive band whether sideslip, it is possible to fundamentally solve this difficult problem, because the compressed air of Tiny pore is at 4-6Kg/cm2, and the power that wide-belt sander abrasive band is produced a large amount of abrasive dust when grinding is far smaller than 4-6Kg/cm2, therefore abrasive dust will not form blocking on the detection path of air-flow, it is ensured that the unimpeded and accuracy of detection in detection path, it is to avoid the generation of the disorderly closedown event that background technology exists.2, the design of gas control plate, is the two of technical characteristic of the present utility model.So purpose of design is: owing to gas control plate is by upper plate, lower plugboard and riser constitute recessed slot, upper plate and the upper and lower opposite face of lower plugboard have gas hole and connect pore, gas hole on the same axis and forms air-flow sense channel with connecing pore, if outside position, abrasive band is in gas control plate correspondence holes, gas control plate is in vent flow state, if when position, abrasive band is between gas control plate correspondence holes, gas control plate is in stuffiness stream mode, the vent flow of gas control plate and obstructed air-flow two states control the work of air amplifier thimble, thus control reversal valve work, yaw cylinder operation is controlled by reversal valve, thus reach a detection and the correction action of position, abrasive band.3, air amplifier pushes the design that reversal valve controls the duty of yaw cylinder, is the three of technical characteristic of the present utility model.So purpose of design is: owing to oscillating cylinder is that fine motion coordinates with broadband sanding head, and the controlled air amplifier of duty of reversal valve and the setting of the duty of reversal valve own, therefore reversal valve can set itself duty according to sanding head duty of rectifying a deviation, thus reach whether block the mechanical order of gas channel according to abrasive band and control the swing orientation of yaw cylinder, thus reach the purpose of abrasive band automatic deviation correction.
Technical scheme 1: a kind of wide-belt sander Tiny pore abrasive band position detecting device, compressed air air delivering pipeline is connected with reversal valve inlet end by threeway one tunnel, one tunnel connects with air blowing pressure regulator valve inlet end, air blowing pressure regulator valve outlet side connects with spilehole inlet end in gas control plate, the gross blow hole inlet end that in gas control plate, the outlet blowout air-flow of spilehole inlet end blasts in gas control plate with spilehole opposite face accepts air-flow, the air-flow of gross blow hole outlet side is connected with air amplifier inlet end by gas circuit, air-flow pushes thimble through air amplifier reinforcement and realizes reversal valve switch motion, in reversal valve, two-way outlet side connects with yaw cylinder intake end respectively.
Technical scheme 2: the detection method of a kind of wide-belt sander Tiny pore abrasive band position detecting device, compressed air air delivering pipeline inlet end is passed through 4-6kg/cm2Compressed air, compressed air is divided into two-way by the threeway in compressed air air delivering pipeline, one tunnel is directly entered reversal valve, another road is to pressure regulator valve of blowing, compressed air is passed through gas control plate through air blowing pressure regulator valve, the air-flow that in gas control plate, gas hole blows out blasts the pore that connects in face in contrast and accepts air-flow, owing to gas hole aperture is less than connecing air vent aperture, the Tiny pore connecing pore acceptance is passed through air amplifier, air-flow forces through air amplifier amplification and pushes reversal valve work on the thimble in air amplifier, reversal valve controls yaw cylinder, yaw cylinder controls sanding head action；If outside position, abrasive band is in gas control plate correspondence holes, gas control plate is in vent flow state, if when position, abrasive band is between gas control plate correspondence holes, gas control plate is in stuffiness stream mode, the vent flow of gas control plate and obstructed air-flow two states control the work of air amplifier thimble, thus control reversal valve work, control yaw cylinder operation by reversal valve, thus reach a detection and the correction action of position, abrasive band.
The present invention is compared with background technology, and one is fundamentally to solve the contaminated state of Photoelectric Detection that background technology exists, and then often results in the generation of sander disorderly closedown phenomenon；Two is in the abrasive band of wide-belt sander is detected, and not only detection sensitivity is high, and rectifies a deviation in time, reliably.
