Abstract
The invention relates to a device for detecting the position of a sanding belt of a wide belt sanding machine through micro air flow and a control method. According to the device, the micro air flow is adopted for detecting whether the sanding belt of the wide belt sanding machine deviates. A branch of a compressed air conveying pipeline is communicated with the air inlet end of a reversing valve through a tee joint, and a branch of the compressed air conveying pipeline is communicated with the air inlet end of an air blowing pressure-regulating valve. The air outlet end of the air blowing pressure-regulating valve is communicated with the air inlet end of a small air hole of an air control insertion plate, the outlet of the air inlet end of the small air hole of the air control insertion plate blows air flow, the air flow is blasted into the air control insertion plate, and a large air hole opposite to the small air hole receives the air flow. The air outlet end of the large air hole is communicated with the air inlet end of an air pressure amplifier through an air channel. The air flow is in switching cooperation with the control end of a reversing valve through a centre in the air pressure amplifier, and the two air outlet ends of the reversing valve are respectively communicated with the air inlet end of an oscillating cylinder. The device and control method have the advantage that the problem that due to the fact that a photoelectric detection head is polluted in the background technology, the disorderly closedown phenomenon of the sanding machine occurs frequently is solved fundamentally.
Description
Technical field
The present invention relates to a kind ofly adopt micro-air-flow as detecting wide-belt sander the abrasive band whether micro-air-flow of wide-belt sander abrasive band position detecting device and the control method of sideslip, belong to wide-belt sander abrasive band controlling organization and manufacture field.
Background technology
CN102814716A, title " a kind of polishing machine abrasive band automatic deviation rectifying mechanism ", comprise infrared sensor, DC servo motor, eccentric wheel, connecting rod, Worm and worm-wheel gearing and deviation correcting roller; Described infrared sensor, DC servo motor and Worm and worm-wheel gearing are all fixed on polishing machine base plate; Described deviation correcting roller coaxial sleeve, on the worm screw of Worm and worm-wheel gearing, and connects by bearing, and deviation correcting roller can freely be rotated on worm screw; Infrared sensor detects polishing machine abrasive band sideslip situation, and offset signals is passed to peripheral control unit; Described DC servo motor is controlled by peripheral control unit, and DC servo motor output shaft is coaxially connected with eccentric wheel one end, and DC servo motor output shaft band movable eccentric wheel rotates; The described eccentric wheel other end is connected with connecting rod one end is eccentric, and when eccentric wheel rotates, drivening rod swings, and connecting rod swing plane is vertical with eccentric wheel axis; The connecting rod other end is fixed with swinging axle, and swinging axle axis, perpendicular to connecting rod swing plane, drives swinging axle to rotate during connecting rod swing; Described swinging axle is coaxially fixedly connected with the worm gear of Worm and worm-wheel gearing.Its weak point: adopt optoelectronic switch to detect position, abrasive band; output signal to controlling organization action practical function; because sander is a kind of high efficiency grinding mode; produce a large amount of abrasive dusts; machine intimate environment is very poor; and the testing environment that optoelectronic switch requires is higher, therefore often occur because camera lens pollutes the disorderly closedown producing, have a strong impact on the normal use of machine.
Summary of the invention
Purpose of design: avoid the weak point in background technology, design and a kind ofly adopt micro-air-flow as detecting wide-belt sander the abrasive band whether micro-air-flow of wide-belt sander abrasive band position detecting device and the control method of sideslip.
Design: in order to realize above-mentioned purpose of design.1, adopting micro-air-flow as detecting the whether design of sideslip of wide-belt sander abrasive band, is one of technical characterictic of the present invention.The object of design is like this: wide-belt sander is when work, High Rotation Speed grinding is done in abrasive band on sanding head, need to do axial swinging back and forth along touch roll simultaneously, its effect is control band, chip removal, a plurality of effects such as improvement grinding state, for the swinging track in abrasive band being controlled in the scope needing, background technology adopts optoelectronic switch to detect position, abrasive band conventionally, by photoelectric output signal, control the swing of sanding head, but because sander is a kind of high efficiency grinding mode, during grinding, to produce a large amount of abrasive dusts, this grinding causes machine intimate environment very poor, make to require in detection that optoelectronic switch that testing environment is higher rectifies a deviation in sander abrasive band usually in a Photoelectric Detection contaminated state, so often cause disorderly closedown, have a strong impact on the normal use of sander.The application adopts micro-air-flow as detecting whether sideslip of wide-belt sander abrasive band, can fundamentally solve this difficult problem, because the compressed air of micro-air-flow is at 4-6Kg/cm
2, and the power of wide-belt sander abrasive band a large amount of abrasive dusts that produce when grinding is far smaller than 4-6Kg/cm
2, so abrasive dust can not form obstruction on the detection path of air-flow, guaranteed to detect the unimpeded and accuracy of detection in path, avoided the generation of the disorderly closedown event that background technology exists.2, the design of gas control plate is two of technical characterictic of the present invention.The object of design is like this: because gas control plate is by upper plate, lower plugboard and riser form recessed slot, the upper and lower opposite face of upper plate and lower plugboard has gas hole and connects pore, gas hole and connect pore on same axis and form air-flow sense channel, when if position, abrasive band is in outside corresponding two holes of gas control plate, gas control plate is in ventilation stream mode, when if position, abrasive band is between corresponding two holes of gas control plate, gas control plate is in stuffiness stream mode, ventilation stream and the obstructed air-flow two states of gas control plate are controlled the work of air amplifier thimble, thereby control reversal valve work, by reversal valve, control yaw cylinder operation, thereby one that reaches position, abrasive band is detected and correction action.3, air amplifier pushes the design that reversal valve is controlled the duty of yaw cylinder, is three of technical characterictic of the present invention.The object of design is like this: because oscillating cylinder is fine motion with broadband sanding head, coordinate, and the setting of the controlled air amplifier of the duty of reversal valve and the duty of reversal valve own, therefore reversal valve can be set itself duty according to the sanding head duty of rectifying a deviation, thereby reach the mechanical order of whether blocking gas channel according to abrasive band, control the swing orientation of yaw cylinder, thereby reach the object of abrasive band automatic deviation correction.
